"You will tell us, I am sure."
|

"It jumps out. But do you what what happens when you put the

frog in a pot of cool water and then slowly bring it to a boil? You know

what happens then?"

## 1 Review Questions
|
||||||
|
Do one practice problem
|
||||||
|
|
||||||
|
### 1.1 MaxNum
|
||||||
|
```
|
||||||
|
maxNum = -1
|
||||||
|
for num in numbers
|
||||||
|
if num < maxNum then
|
||||||
|
maxNum = num;
|
||||||
|
end
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
parameter n is length of the array of number
|
||||||
|
|
||||||
|
we will prove that, for every non-negative integer n, the maximum time to find the max num is Ο(n)
|
||||||
|
|
||||||
|
for n = 1 this is true because the maximum number is always the first number we check
|
||||||
|
for n =2 this is true because the maximum number is always on of the first two numbers we check
|
||||||
|
|
||||||
|
for any n >0, assuming this is true for all n-1, this is true at n because the maximum amount of number to check is never greater than n
|
||||||
|
|
||||||
|
∴ by induction, the time comnplexity is Ο(n)

# Analysis of recursion algorithms
|
||||||
|
- induction and recursion are linked
|
||||||
|
- inductive approach is esential for understanding time-complexity of resursive algorithms
|
||||||
|
|
||||||
|
## 2 Proof by induction
|
||||||
|
[Induction](content/notes/induction.md)
|
||||||
|
Find a (positive integer) _parameter_ that gets smaller in all recursive calls
|
||||||
|
Prove inductively that "for all values of the parameter, the result computed is correct"
|
||||||
|
To do that:
|
||||||
|
- check correctness is all non-recursive cases
|
||||||
|
- check correctness in recursive cases assuming correcness in the recursive calls
|
||||||
|
|
||||||
|
## 3 Examples
|
||||||
|
### 3.1 Quicksort
|
||||||
|
[divide and conquer](None) algorithm
|
||||||
|
sorts a range in an array (a group of elements between some lower index, $lo$ inclusive and some upper index $hi$ exclusive) as follows:
|
||||||
|
- If length of range $(hi - lo)$ is at most 1 -> do nothing
|
||||||
|
- otherwise, choose a pivot p (e.g., the element at $lo$) and:
|
||||||
|
- place all items less that p in positions $lo$ to $lo +r$
|
||||||
|
- place all items >= p in positions $lo +r+1$ to $hi$
|
||||||
|
- place p in position $lo+r$
|
||||||
|
- call quicksort on the ranges $lo$ to $lo + r$ and $lo+r+1$ to $hi$
|
||||||
|
|
||||||
|
#### 3.1.1 Proof
|
||||||
|
parameter is $hi - lo$
|
||||||
|
|
||||||
|
the parameter gets smaller in all recusive call because we always remove the element $p$ so, even if it is the smallest or largest element of the range ,,the recursive call has a range of size at most $hi - lo - 1$
|
||||||
|
|
||||||
|
the non-recursive case is correct because if we have 1 or fewer elements in a range they are already sorted
|
||||||
|
|
||||||
|
in the recirsive case, since all the elements before $p$ are smaller than it and we assume they get sorted correctly be quicksort, and the same happens for the elements larger than p, we will get a correctly sorted array
|
||||||
|
|
||||||
|
|
||||||
|
### 3.2 Fibonacci 1
|
||||||
|
```python
|
||||||
|
def fib(n)
|
||||||
|
if n <= 1
|
||||||
|
return 1
|
||||||
|
return fib(n-1) + fib(n-2)
|
||||||
|
```
|
||||||
|
|
||||||
|
line 1 -> always executed
|
||||||
|
line 2 -> executed if n<=1
|
||||||
|
line 4 -> executed if n>1, cost equal to cost of callling fib(n-1), fib(n-2), and some constant cost for the addition and return
|
||||||
|
|
||||||
|
#### 3.2.1 Cost bounds/Proof
|
||||||
|
if we let T(n) denote the time required for evaluating fib(n) using this algorithm this analysis gives:
|
||||||
|
|
||||||
|
>## $T(0) = T(1) = C$
|
||||||
|
>## $T(n) = D + T(n-1) + T(n-2)$
|
||||||
|
|
||||||
|
where c and d are some positive (non-zero) constants.
|
||||||
|
|
||||||
|
- this shows that T(n) grows at least as quick as fib(n)
|
||||||
|
- even if $D=0$ we'd get $T(n) = C \times fib(n)$
|
||||||
|
- growth rates are the same $\therefore$ exponential (at least $1.6^n$) and far too slow
|
||||||
|
|
||||||
|
> A recurive algorithm that makes two or more recurive calls with parameter values close to the original will generally have exponential time complexity
|
||||||
|
|
||||||
|
### 3.3 Fibonacci 2
|
||||||
|
```python
|
||||||
|
def fibPair()
|
||||||
|
if n == 1
|
||||||
|
return 1, 1
|
||||||
|
a,b = fibpair(n-1)
|
||||||
|
return b, a+b
|
||||||
|
```
|
||||||
|
line 1 -> always executed some constant cost
|
||||||
|
line 2-> executed if n=1, some constant cost
|
||||||
|
line 4-> executed if n>1, cost equal to cost of calling fibPair(n-1)
|
||||||
|
line 5 -> executed if n>1, some constant cost
|
||||||
|
|
||||||
|
#### 3.3.1 Proof
|
||||||
|
it's true for $n-1 by design$
|
||||||
|
If it's true at n-1 then the result of computing fibpair(n) is:
|
||||||
|
|
||||||
|
$(f_{n-1}, f_{n-1} + f_{n-1}) = (f_{n-1}, f_n)$
|
||||||
|
|
||||||
|
which is what we want
|
||||||
|
|
||||||
|
#### 3.3.2 Cost bounds
|
||||||
|
if we let P(n) denote the time required for evaluating fib(n) using this algorithm this analysis gives:
|
||||||
|
|
||||||
|
$P(1) = C$
|
||||||
|
$P(n) = P(n-1) + D\ for\ n>1$
|
||||||
|
|
||||||
|
where $C$ and $D$ are some positive (non-zero) constants.
|
||||||
|
|
||||||
|
|
||||||
|
Claim: $P(n) = C + D(n-1)$
|
||||||
|
|
||||||
|
By induction:
|
||||||
|
it's true for n = 1 since,
|
||||||
|
|
||||||
|
$P(1) = C$
|
||||||
|
$C+D\times(1-1)=C$
|
||||||
|
|
||||||
|
suppose that it's true for n-1. Then it's true for n as well because
|
||||||
|
|
||||||
|
$P(n) = P(n-1) + D$
|
||||||
|
$\ \ \ \ \ \ \ \ \ = C+D\times(n-2)+D$
|
||||||
|
$\ \ \ \ \ \ \ \ \ = C+D\times(n-1)$
|
||||||
|
|
||||||
|
$\therefore$ By induction it's true for all $n>=1$
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
$P(n)$ is the time for evaluating $fibPair(n)$ using this algorithm. This analysis gives:
|
||||||
|
|
||||||
|
$P(1) = C$
|
||||||
|
$P(n) = P(n-1) +D$
|
||||||
|
|
||||||
|
where C and D are some positive constants
|
||||||
|
|
||||||
|
#theorem
|
||||||
|
> ## $P(n) = C+D\times(n-1)$
|
||||||
|
> in particular, $P(n) = \theta(n)$
|
||||||
|
|
||||||
|
> A recursive algorithm that make one recurive call with a smaller value and a constant amount of additional work will have at most linear time complexity

# COSC201 Assignment 1: Counting the seas
|
||||||
|
|
||||||
|
## 1 Due : 11:59 p.m. Friday, April 1, 2022
|
||||||
|
[9474308Hughes](None)
|
||||||
|
## 2 Introduction
|
||||||
|
|
||||||
|
Imagine a square world consisting of cells each of which is either land or water. A
|
||||||
|
computational cartographer’s paradise if you will. Anyhow, it turns out that a number
|
||||||
|
of such worlds exist of varying sizes and varying proportions of land to water. Your
|
||||||
|
continuing mission has been to search out these strange worlds and count how many
|
||||||
|
distinct bodies of water there are on each of them.
|
||||||
|
|
||||||
|
Here’s a world that you discovered recently – its dimensions are 8 × 8 and it has only
|
||||||
|
14 land cells.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Obviously, in this world there is only one giant sea. On the other hand, another world
|
||||||
|
with a 10 × 10 grid was also recently discovered:
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This world is dominated by land, and there are 10 seas. You may disagree, and think
|
||||||
|
there are 15 seas, but water cells are considered to be part of the same sea if they meet
|
||||||
|
along an edge **or** at a corner.
|
||||||
|
|
||||||
|
Exploration is a complicated and expensive business and the thoughts of your superiors
|
||||||
|
have turned to simulation – that is, to creating imaginary worlds of this type in order
|
||||||
|
to try and understand how the number of seas changes depending on the size of the
|
||||||
|
underlying grid and the ratio of water to land.
|
||||||
|
|
||||||
|
### 2.1 Raw materials
|
||||||
|
|
||||||
|
You will be provided with a number of Java classes. These include:
|
||||||
|
|
||||||
|
- All the union-find implementations we’ve looked at.
|
||||||
|
- A classMap.javathat represents maps of the type we’re interested in. This class includes a number of convenience methods for various tasks. For instance:
|
||||||
|
- indexing the cells of a map from 0 in the top left corner and then increasing from left to right and top to bottom (so, in the 10 × 10 grid the first row contains cells 0 to 9, the second 10 to 19, the third 20 to 29, and so on);
|
||||||
|
- recognising the type of each cell (by index or coordinates);
|
||||||
|
- identifying all the neighbours of a given cell (by index).
|
||||||
|
|
||||||
|
Using these classes, you are asked to produce some more code and to conduct and
|
||||||
|
report on some experiments.
|
||||||
|
|
||||||
|
|
||||||
|
### 2.2 Code submission (5 points)
|
||||||
|
|
||||||
|
The code you submit for this assignment will be a single class calledMapAnalyser.
|
||||||
|
Skeleton code for that class will be provided and its Javadoc will specify the require-
|
||||||
|
ments in detail. However, these and the required underlying algorithms are also dis-
|
||||||
|
cussed briefly below.
|
||||||
|
|
||||||
|
MapAnalyser(Map m)
|
||||||
|
|
||||||
|
The constructor for aMapAnalyserrequires aMapinstance. All of its methods refer to
|
||||||
|
this underlyingMap.
|
||||||
|
|
||||||
|
countSeas()
|
||||||
|
|
||||||
|
This method returns an integer which is the total number of seas of the underlyingMap.
|
||||||
|
To compute this number you must be able to identify the seas, i.e., which water cells
|
||||||
|
belong to the same seas. This is exactly the kind of task that the union-find framework
|
||||||
|
is designed for.
|
||||||
|
|
||||||
|
Specifically, given a map you can initialise aUnionFindinstance whose size is the
|
||||||
|
total number of cells in the map. Then, you can iterate once over the cells of the map –
|
||||||
|
whenever you find a water cell, you can do a union operation between it and its water
|
||||||
|
neighbours. At the end of this process, two water cells belong to the same sea if and
|
||||||
|
only if they are in same set of the partition (i.e., if and only if they have the samefind
|
||||||
|
value).
|
||||||
|
|
||||||
|
There are a number of options about how to use this idea to count seas (you can do it
|
||||||
|
as you construct the final state of the union-find instance, or after you have done so).
|
||||||
|
The choice is up to you.
|
||||||
|
|
||||||
|
seaSize(int r, int c)
|
||||||
|
|
||||||
|
This method just returns the total number of cells belonging to the same sea as the cell
|
||||||
|
in rowrand columnc. If this cell is land rather than water it should just return the
|
||||||
|
value 0.
|
||||||
|
|
||||||
|
### 2.3 Written submission (5 points
|
||||||
|
|
||||||
|
Please submit the answers to the following questions as a single **PDF** document with
|
||||||
|
filename of the form314159Pi.pdfwhere 314159 is replaced by your ID number
|
||||||
|
andPiis replaced by your surname. There are no formal requirements for the format
|
||||||
|
of your submission, but presentation, spelling and grammar are all important elements
|
||||||
|
which will account for roughly 40% of the marks for this part of the assignment.
|
||||||
|
|
||||||
|
The written answers to questions one and two could be a couple of paragraphs each
|
||||||
|
(or a bit longer) along with supporting data. A single paragraph (and possibly some
|
||||||
|
pseudocode) is enough to answer question three.
|
||||||
|
|
||||||
|
1. The efficiency of the various union-find instances affects how large a square map
|
||||||
|
can be analysed. A reasonable length of time for a single computation might be
|
||||||
|
something on the order of a second. Conduct experiments usingUF1,UF2,UF3,
|
||||||
|
andUF4to determine rough values for that limit on the hardware you are us-
|
||||||
|
ing when the probability of a cell being water is 0. 5. Describe those experiments
|
||||||
|
(including the number of repetitions) and report on their results (a table or chart
|
||||||
|
would be appropriate). Comment briefly on whether the outcomes match our the-
|
||||||
|
oretical discussions of the four different algorithms and how changing the water
|
||||||
|
probability might affect their performance.
|
||||||
|
2. Consider 10 × 10 , 100 × 100 , and 1000 × 1000 maps. Conduct experiments to
|
||||||
|
try and determine the proportion of water needed on each so that on average
|
||||||
|
there are two or fewer seas. Describe those experiments (including the number of
|
||||||
|
repetitions - this should be large enough that you have confidence in the results
|
||||||
|
you’re claiming) and report on their results.
|
||||||
|
3. Suppose that we also wanted to count the islands. How would you do that - and
|
||||||
|
what changes to the code might be needed?

# Assignment 3
|
||||||
|
|
||||||
|
**Deadline: Friday 27th of May 2022, 5pm via Blackboard (35% of final mark)**
|
||||||
|
|
||||||
|
## 1 Project: Prototypical Mobile App Development
|
||||||
|
### 1.1 Aim
|
||||||
|
- conecptual design and prototypical implementation of a application for mobile devices
|
||||||
|
- Usage of an iterative development model increasing the fidelity of the developed prototype
|
||||||
|
- Conduct brainstorming, develop personas and scenarios, create storyboard, create low fidelity prototypes (explore alternatives), informal evaluation, create high fidelity prototypes
|
||||||
|
|
||||||
|
### 1.2 Deadlines
|
||||||
|
- Friday 8th of April: Email to Jonthan (sutjo752@student.otago.ac.nz) to indicate group/ indivdual work and preliminary topic idea
|
||||||
|
- Friday 27th of May: Final recorded presentation and additional material summarising the prototypical mobile App development
|
||||||
|
|
||||||
|
### 1.3 Brainstorming:
|
||||||
|
- Explore user interface alternatives and compare against existing products similar to your app (or most similar apps)
|
||||||
|
- Document process: E.g. what are the different ideas, alternatives developed and existing solutions, what was the reason the choosing the winning idea
|
||||||
|
- Keep it short, make use of visual documentation (e.g. drawings, photos, Post-Its) and support it with text, mindmap(s) can me usefull to document brainstorming
|
||||||
|
- Documentation needs to provide evidence that you a) considered existing solutions (needfinding) and b) explored different alternatives
|
||||||
|
|
||||||
|
### 1.4 Personas and Scenarios:
|
||||||
|
- Conceptually develop personas and scenarios (at least two)
|
||||||
|
- Document final personas (also considering different type of personas) and scenarios
|
||||||
|
- Keep it short and see examples in the lectures for guidance
|
||||||
|
|
||||||
|
### 1.5 Storyboard:
|
||||||
|
- Develop a visual storyboard out of your scenario description
|
||||||
|
- See lecture on storyboards for tricks on developing a short and concise storyboard
|
||||||
|
- Digital storyboard or free hand sketch are both fine
|
||||||
|
|
||||||
|
### 1.6 Low fidelity prototypes:
|
||||||
|
- Develop low fidelity prototypes for your envisioned app using techniques explained in the lecture (paper-based prototypes)
|
||||||
|
- We expect 6-10 “screens” that should be prototypically developed
|
||||||
|
- Explore alternatives for the interface and document all (photos are ok when using pen-based sketches)
|
||||||
|
- Consider and document the flow within the app (relation and pathways between different screens)
|
||||||
|
|
||||||
|
### 1.7 Document design decisions / informal evaluation
|
||||||
|
- Which of the ideas from the different low fidelity prototypes did or did not work
|
||||||
|
- Document the identified issues by linking them to the design heuristics and mention the proposed solution(s)
|
||||||
|
- E.g. one aspect from one prototype worked better than in the alternative prototype because there was an issue with “Consistency”….
|
||||||
|
|
||||||
|
### 1.8 High fidelity prototype:
|
||||||
|
- Develop a high fidelity prototype from the knowledge gained with your low fidelity prototype
|
||||||
|
- Create the higher fidelity prototype by choosing a method (e.g. could be prototype toolkits such as Balsamiq, Adobe XD, …, some of them have a free trial period you are not expected to buy those, could be template based approaches using images of UI elements, …)
|
||||||
|
- Consider which interface elements you use because of size constraints within a mobile interface
|
||||||
|
- Outline the flow within the app (relation and pathways between different screens)
|
||||||
|
- Document using screenshots etc.
|
||||||
|
|
||||||
|
### 1.9 Submission:
|
||||||
|
- ~7min presentation slides with max. 7 slides (Powerpoint, Keynote, or Pdf) summarising the key aspects of your prototypical development
|
||||||
|
- Professional look: Less text more graphics, illustrations, and other media material (video?)
|
||||||
|
- This presentation is no advertisement or sales pitch but a summary of the work you did with some key insights you learned along the way
|
||||||
|
- Record your presentation (slides and with audio, video optional), we recommend Zoom for doing this
|
||||||
|
- Submit the recording of your presentation
|
||||||
|
- Submit all material (e.g. more detailed storyboards, alternatives explored, paper-based prototypes not covered in the presentation, full high level prototypes)
|
||||||
|
- Deadline: Friday 27th of May 2022, 5pm via Blackboard (35% of final mark)

# Big-O
|
||||||
|
>Big O means $f(n) = O(g(n))$ if there is some constant $A > 0$ such that for all sufficiently large n, $f(n) ≤ A × g(n).$
|
||||||
|
|
||||||
|
- Big O provides *upper bounds* only. (usually on worst case runtimes)
|
||||||
|
- sometimes cost will be much less
|
||||||
|
- does not take special cases into account
|
||||||
|
- upper bound
|
||||||
|
- $O$ says that $g(n)$ provides an upper bound for $f(n)$
|
||||||
|
- "Insertion sort is $O(n^2)$" -> the maximum number of basic operations in never more than some constanct times $n^2$
|
||||||
|
- if $f(n) =O(g(n))$ then the opposite is also true
|
||||||
|
- usually $f(n)$ is complex but $g(n)$ is very simple

|
||||||
|
>Big theta means $f(n) = \Theta(g(n))$ if there are constants 0 < B < A such that for all sufficiently large n, ==$B × g(n) ≤ f(n) ≤ A × g(n)$==
|
||||||
|
|
||||||
|
- Upper and lower bound
|
||||||
|
- $Θ$ says that $g(n)$ provides **upper** and **lower** bound for $f(n)$
|
||||||
|
- "selection sort is $\Theta(n^2)$" -> the maximum number of operations will be bounded bothh above and below by some constant times $n^2$
|
||||||
|
- $f(n) = \Theta(g(n))$ means that f and g have similar growth rates
|
||||||
|
- if $f(n) = \Theta(g(n))$ then the opposite is also true
|
||||||
|
- usually $f(n)$ is complex but $g(n)$ is very simple

#### 0.1.1 Review Questions
|
||||||
|
1. name and describe two methodologies for using branches. Acronym for methodologies -> (GOOF)
|
||||||
|
- gitflow
|
||||||
|
- very structured
|
||||||
|
- uses a set of branches each with a specific purpose
|
||||||
|
- On the main branch
|
||||||
|
- focused on not creating new branches
|
||||||
|
- smaller self-contained commits are better
|
||||||
|
- Off the main branch
|
||||||
|
- most work occurs on a branch
|
||||||
|
- Feature branches
|
||||||
|
- each features has it's own branch which is merged and ~~deleted~~ can be worked on after completion
|
||||||
|
1. what is the difference between a topic/feature branch and a persistent branch
|
||||||
|
- feature branch
|
||||||
|
- used for a fixed term task such as a bug or a feature
|
||||||
|
- persistent branch
|
||||||
|
- branch that exists for the lifetime of the project
|
||||||
|
|
||||||
|
2. what is continuous intergration

# Branch
|
||||||
|
Split current dev path into two to work on e.g., a bug or a feature
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 1 Overview
|
||||||
|
- allows users to work independently
|
||||||
|
- development continues independently along each branch
|
||||||
|
- can easily switch between branches
|
||||||
|
- can push a branch without affecting others
|
||||||
|
- branches can be merged back into the original
|
||||||
|
- always at least one main branch (usually master, main, trunk)
|
||||||
|
|
||||||
|
## 2 Default branch
|
||||||
|
used to be called master
|
||||||
|
now called main
|
||||||
|
|
||||||
|
## 3 Methodologies
|
||||||
|
### 3.1 Working on the main branch
|
||||||
|
focuses on not creating branches
|
||||||
|
- over time long branches become difficult to merge
|
||||||
|
- smaller, self-contained changes are encouraged
|
||||||
|
- focus on main code objective, avoiding side-experiments
|
||||||
|
|
||||||
|
sometimes this is not possible
|
||||||
|
- complex bugs or features need branches
|
||||||
|
|
||||||
|
pair programming
|
||||||
|
- e.g., vs code allows multiple developers to work on the same code at the same time.
|
||||||
|
|
||||||
|
### 3.2 Working off the main branch
|
||||||
|
- branches can be shared with teams
|
||||||
|
- still isolated commits from the main branch
|
||||||
|
- more commits can be added to a branch _after_ it has been merged
|
||||||
|
|
||||||
|
### 3.3 Feature branching
|
||||||
|
all new features are developed in a separate branch
|
||||||
|
merging to the branch "adds" that feature
|
||||||
|
after a feature is added, it call still be added to using the same branch
|
||||||
|
|
||||||
|
### 3.4 Gitflow
|
||||||
|
viewed as ovecomplicated
|
||||||
|
a set of shell scripts helps it be used
|
||||||
|
highly structured
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- main branch -> branch has commit for release versions
|
||||||
|
- develop branch -> branch is where development occurs
|
||||||
|
- feature branch -> branches branch off development branch
|
||||||
|
- release branch -> branch polishes for release
|
||||||
|
- hotfix -> branches of main branch thence into develop
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 4 continuous integration
|
||||||
|
- [CI vs feature branch](https://www.youtube.com/watch?v=v4lijkq6Myfc)
|
||||||
|
- [cl vs feature branch](https://www.youtube.com/watch?v=IXQEi1O5!OI)
|
||||||
|
|
||||||
|
## 5 Topic/feature branch
|
||||||
|
- created for a specific purpose .e.g, bug/feature
|
||||||
|
- can pull from remote without marge conflicts (should be only one person working on branch)
|
||||||
|
- the more short-lived branches are the less likely there are to be merge conflicts with main
|
||||||
|
|
||||||
|
## 6 Persistent branch
|
||||||
|
- long term branch that exists for the lifetime of the project
|
||||||
|
- e.g.,
|
||||||
|
- release branches
|
||||||
|
- release v1, start on v2
|
||||||
|
- security flaw in v1, needs to be fixed
|
||||||
|
- v2 not finished yet
|
||||||
|
- create branch at last v1 commit and fix there
|
||||||
|
- also fix in v2 (if applicable)
|
||||||
|
- v1 branch will last until v2 is released
|
||||||
|
- specialsed versions of code base
|
||||||
|
- e.g., to support specific platforms or hardware
|
||||||
|
- e.g., to support feaures for a specific customer
|
||||||
|
- features for this specilised version on go on that branch
|
||||||
|
- keeps specialised code out of main codebase

# Business functions
|
||||||
|
- what the business ought to be doing
|
||||||
|
- _not_
|
||||||
|
- who, how, stucture, tech
|
||||||
|
|
||||||
|
each business function becomes a set of features within an info system
|
||||||
|
|
||||||
|
## 1 Id business functions
|
||||||
|
- verb phrases
|
||||||
|
- id what the business ought to be doing ⇒ e.g., "accept payment from customer"
|
||||||
|
- id how => "we accept payments online banking and credit card"
|
||||||
|
- always ask "what is the objective"
|
||||||
|
- remove redundancies
|
||||||
|
- model the id'd functions as _use cases_
|
||||||
|
|
||||||
|
## 2 Use case
|
||||||
|
"A list of actions defining the interactions betweeen a role and a system to achiece a goal"
|
||||||
|
high level description of how people interact with a system
|
||||||
|
|
||||||
|
story of how the business works
|
||||||
|
|
||||||
|
should be:
|
||||||
|
- simple
|
||||||
|
- aimed at stakeholders
|
||||||
|
- understandable by non-tech people
|
||||||
|
- should use ubiquitous language
|
||||||
|
- also useful for system devs
|
||||||
|
|
||||||
|
can use text (Cockburn, fowler) or diagrams (function catalog, UML case diagrams)
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 3 UML
|
||||||
|
unified modeling language
|
||||||
|
- use case - class - state - activity - sequence - deployment etc

# BPMN - Business Process Model and Notation
|
||||||
|
- graphical diagramming language
|
||||||
|
- free international vendor standard developed by the object management group
|
||||||
|
- shows only the order of activites
|
||||||
|
- when, not under what conditions
|
||||||
|
- do not:
|
||||||
|
- detail the activites
|
||||||
|
- describe how it is informed
|
||||||
|
|
||||||
|
### 0.1 swimlanes
|
||||||
|
identify the business role for each activity
|
||||||
|
|
||||||
|
### 0.2 Other features
|
||||||
|
- looping back
|
||||||
|
- types of branch gateway
|
||||||
|
- parallel execution
|
||||||
|
- collaboration with external entities (pools)
|
||||||
|
- executable if using the right infrastructure

|
| visibility of system status | 3 | Call | The the close window button does not leave the meeting. It pops up the small view. If the user closes this window. The user still does not leave the meeting and there is not GUI | make closing the windows prompt the user if they want to leave the meeting |
|
||||||
|
| error prevention | 3 | Call | The application crahed when cadence tried to take a snapshot. Then I could still see him even though he didn't know he was still in the meeting | The snapshot feature should not cause a crash. And when the GUI closes, the user should leave the meeting |
|
||||||
|
| Recognition rather than recall | 3 | N/A | I do not know how to add somebody else as a contact. I found a way to share a link to my profile, but I don’t know how to use a link that was shared with me. | There should be clear and obvious steps on how to add a contact. If the person has no contacts then the buttons should be displayed more prominently. |
|
||||||
|
| Visibility of system status | 3 | Call | After Skype restarted from the snapshot button crash, the interface seemed like I wasn’t in a call: there was no call overlay, I couldn’t see or hear the other person, and the buttons prompted to start a call rather than stop it. However, my partner could actually see and hear me the whole time, without me knowing! | The application should always tell you when you are in a call. |
|
||||||
|
| User control and freedom | 3 | Private conversation | Logging out and logging in again permanently deletes the entire private conversation on your side without warning. | It should remember the conversation, or if this isn’t possible, it should warn you about the consequences before you log out. |
|
||||||
|
| Visibility of system status | 3 | Call | If a skype window is closed while in a audio or video call, you remain in the call, despite the app being closed. | Either have a warning that the app is closing but you will remain in the call, or have a warning that closing the app will terminate your connection to the call |
|
||||||
|
| Visibility of system status | 2 | Audio/video settings | It is not clear whether or not the microphone test is running | There should be a visible indicator showing that the microphon test is running |
|
||||||
|
| Visibility of system status | 2 | Screenshare | The only indicator that you are sharing your screen is the button changing from “start sharing” to “stop sharing”. It is easy to forget you are sharing, which could potentially cause huge embarrassment! | There should be a permanent indicator that is visible even while using other applications. |
|
||||||
|
| Help users recognise and recover from errors | 2 | Account creation | You cannot use a PNG image as a profile picture, only a JPEG image. | Allow PNG images too, or automatically convert them when the user tries to pick them. |
|
||||||
|
| Flexibility and efficiency of use | 2 | Audio/video settings | When adjusting your audio and videos settings the setting for your webcam is hidden | It should be moved up so the use doesn't have to scroll |
|
||||||
|
| recognition rather than recall | 2 | Call | After opening the sidebar during a call there is no indication of how to hide it | There should be a button to close the sidebar during a call |
|
||||||
|
| User control and freedom | 2 | Mini Viewer | When ‘minimising’ Skype into a mini-player while on video call, the icon for screen-share is visible, and easily confused with the ‘maximise’ button to return the screen to the normal viewer | Have the button for screen share clearer of its purpose, and have a resize option when in mini-player |
|
||||||
|
| Match between system and the real world | 2 | Contacts list | Contacts who have sent you a message are not displayed in the “chats” section until you send a message back. | Text chats should always be displayed in the text chats section. |
|
||||||
|
| consistency and standards | 2 | Call | When one participant enters together mode, it force all the participant into together mode. But the users must all individually leave together mode. | It should be made clear that this is how is works as this was unexpeted behaviour |
|
||||||
|
| Flexibility and efficiency of use | 2 | Call | To click the horizontal dot menu in the bottom left the user must mouse over the react button which opens a popup. This menu usually closes after the mouse is moved off but sometimes it stays | The react menu should be moved or the mouse over function should be fixed |
|
||||||
|
| User control and freedom | 2 | Call | My partner has the ability to use a custom background image, but I don’t have this feature on my end. | Everybody should have the feature! I don’t know why I don’t have it. |
|
||||||
|
| Match between system and the real world | 2 | Private conversation | There is a feature to start a private conversation. Does this imply that conversations are usually not private? | The application should describe what a private conversation means, and explain whatever the downsides are that mean that it can’t be the default option. |
|
||||||
|
| Aesthetic and minimalist design | 2 | Call | When switching applications, Skype opens a floating window to contain the call, which will overlap other applications. | This feature is helpful but there needs to be a way to permanently dismiss it so people can work while in a call. |
|
||||||
|
| Consistency and standards | 2 | N/A | Quitting and restarting the application caused me to be logged out. | It’s a program that is installed on my computer, so it makes sense to keep me logged in. |
|
||||||
|
| recognition rather than recall | 2 | Call | not clear how to exit together mode | Have some indicator of |
|
||||||
|
| User control and freedom | 2 | Text chat | You cannot send a message that starts with a slash. | You should be able to send messages starting with a slash. |
|
||||||
|
| Recognition rather than recall | 2 | General | The toolbar that typically runs along the top of the screen is only available/viewable on the app after pressing alt, and making any action outside of the toolbar removes it again | Have an option to toggle toolbar on/off, and/or make it clearer that alt engages the toolbar |
|
||||||
|
| Help and documentation | 2 | General | To get help with Skype, the toolbar has to be toggled or settings must be opened and navigated through to find the help section | Have a more easily accessible help button, perhaps near the notifications/create group .etc |
|
||||||
|
| Visibility of system status | 2 | Chat | When removing a message, it is not made clear whether it will remove the message for everyone, or just yourself | Clarify that removing the message removes it for all participants |
|
||||||
|
| Flexibility and efficiency of use | 2 | Chat | To view bookmarked messages the user must navigate through their own profile to the bookmarks tab, where all bookmarks from all chats are kept, unsorted | Have an option to view bookmarked chats from certain groups, or have sorting criteria (date, group etc) |
|
||||||
|
| Aesthetic and minimalist design | 1 | Profile | When trying to click on your profile, if the status symbol is clicked a dropdown menu appears that gives you the ability to set your status (active, away, DnD etc), but this option is already included in the main dropdown from clicking onto your profile | Remove the separate function to help mis-click prevention |
|
||||||
|
| Match between system and the real world | 1 | DnD popup | When entering Do Not Disturb, a pop-up notifies you that you will not receive notifications while this is on. The popup has three options to exit it, ‘OK’, ‘View Settings’, and ‘Don’t ask me again’ | Improve the wording. Instead of Don’t ask me again, have ‘don’t show me this again’ or something of the like |
|
||||||
|
| User coontrol and freedom | 1 | Mini floating window | There is no dedicated button to maximise the floating window | A dedicated button should be added to maximise the floating window |
|
||||||
|
| Match between system and the real world | 1 | New Group | When a new group is created, there are two options presented for adding people to the group. There is ‘invite’ and ‘add people’ as two separate options. One option is for adding people through a link, and one is for inviting contacts. However, the add people option also contains an option for adding via link. | Remove the invite option, as both are covered under add people. |
|
||||||
|
| Consistency and standards | 1 | General | Throughout the app, there are multiple different designs for the add members button. There are three different actions that can be taken to add members to a group, and they all have different icons | Generalise the icons so that they all follow the same design, that way they are recognisable throughout the application |
|
||||||
|
| user control and freedom | 1 | Audio and video settings| cadence cannot add a custom background | It should at least say why he cant |
|
||||||
|
| Flexibility and efficiency of use | 1 | Call | When a user is using multiple displays, even if the large skype window is visible the floating windows opens | The floating window should no open in this situation |
|
||||||
|
| Help and docmentation | 1 | Call | When in a call by yourself the record button is grayed out and not pressable. There is no indication as to why | On mousing ove the button it should say why it is grayed out |
|
||||||
|
| Aesthetic and minimalist design | 1 | Account creation | On one of the screens, the “continue” button must be clicked twice in order to continue. | The continue button should continue. |
|
||||||
|
| help and documentation | 1 | Chat | no information about what private mode is | more information should be iven to the user |
|
||||||
|
| Aesthetic and minimalist design | 1 | Top of the screen | Informational banners appear here and do not go away until they are interacted with. They do not display helpful information. Sometimes duplicates should appear. | The banners should go away when they are no longer relevant. |
|
||||||
|
| Match between system and the real world | 1 | Call | “Together mode” is poorly named and does not accurately indicate what it will do. | This feature could have a name like “background scene”, or tooltip text, or some other help mechanism. |
|
||||||
|
| Match between system and the real world | 1 | Polls | Somebody clicking or unclicking a poll option sends me a notification sound. These poll events contain little information on their own, so there’s no reason for them to notify immediately. | Do not notify for people clicking polls. |
|
||||||
|
| Match between system and the real world | 1 | Contacts list | There is a feature to “send a contact”, though this offers to send a person their own contact card. | Do not offer to send people their own contact cards. |
|
||||||
|
| Consistency and standards | 1 | Call | The “view” button has an inconsistent appearance. It activates a dropdown but looks like a functional button. | Add an arrow indicator to the button so that it matches the rest of the application’s conventions. |
|
||||||
|
| Consistency and standards | 1 | Polls | It’s not obvious that a poll option highlighted in blue indicates that you should clicked that option. | Poll options should be represented as traditional checkboxes, rather than weird coloured rectangles. This also makes it clear that you can click again to undo your vote, which is already a feature. |
|
||||||
|
| Consistency and standards | 1 | Main menu | There is an option to “download the app”. I am already using the desktop application. | The text should state “phone app” to contrast it from desktop app. |

# Consoles vs Terminals vs Shells
|
||||||
|
- consoles vs terminals/command line shells
|
||||||
|
- console -> io device which is part of a computer (physical terminal)
|
||||||
|
- console is the device: -> terminal is program inside that device
|
||||||
|
- terminal -> text input output environment (can be remote)
|
||||||
|
- windows terminal
|
||||||
|
- [shell](content/notes/shell.md) -> program which the terminal/console sends input to which sends command to the OS
|
||||||
|
- [unix shell](content/notes/unix-shell.md)
|
||||||
|
- powershell
|
||||||
|
- cmd
|
||||||
|
- bash, fish, zsh, ksh, sh, tsch
|
||||||
|
|
||||||
|
#### BREIF HISTORY
|
||||||
|
1. At first only main console
|
||||||
|
2. Then multiple terminals which allowed mulitple people to use one computer
|
||||||
|
3. Graphics support
|
||||||
|
4. Console + terminal merged
|
||||||
|
5. Virtual terminals -> no need for direct hardware control -> replaced by OS
|
||||||
|
|
||||||

# Continuous Integration
|
||||||
|
## 1 What is it
|
||||||
|
continuous --> is always happening
|
||||||
|
integration --> connecting software components
|
||||||
|
|
||||||
|
inc ontrast to ad hoc, occasional integration:
|
||||||
|
- diverging component developmetnamy break integration
|
||||||
|
- repaiing software may be expensive
|
||||||
|
|
||||||
|
supports 'aglile' software dev
|
||||||
|
- like test driven development, help catch issues early
|
||||||
|
|
||||||
|
usually automated
|
||||||
|
|
||||||
|
## 2 Purposes
|
||||||
|
- checking code syntax
|
||||||
|
- e.g., have CI compile the code and report errors
|
||||||
|
- (local devs compilaer may be different from remote)
|
||||||
|
- checking semantics of code
|
||||||
|
- building docs
|
||||||
|
- e.g., auto run javadoc
|
||||||
|
- running projects code tests
|
||||||
|
- auto run JUnit, and report fails
|
||||||
|
|
||||||
|
## 3 Starting CI jobs
|
||||||
|
- from version control
|
||||||
|
- e.g., every commit triggered CI jobs to run
|
||||||
|
- starts on a push to server
|
||||||
|
- manually
|
||||||
|
- on a schedule
|
||||||
|
|
||||||
|
## 4 Runs asnychronously
|
||||||
|
- dont require devs to wait for completion
|
||||||
|
- common to run locally as well as on consistent standard environment
|
||||||
|
|
||||||
|
other timescales
|
||||||
|
- local checks as you commit
|
||||||
|
- checks as you type
|
||||||
|
- checks as you save
|
||||||
|
|
||||||
|
## 5 Output
|
||||||
|
since CI is asynchronous, its feedback is also
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- web badges showing status
|
||||||
|
- can send emails
|
||||||
|
- messaging platform
|
||||||
|
- e.g., slack, discord, teams
|
||||||
|
- webhooks etc
|
||||||
|
|
||||||
|
git project websites usually provide logging interface,
|
||||||
|
will watch scripts in virtual terminal and capture output from CI scripts
|
||||||
|
|
||||||
|
## 6 Github piplines
|
||||||
|
a pipeline has multiple _stages_
|
||||||
|
- e.g., test, build, deploy
|
||||||
|
each stages has multiple _jobs_
|
||||||
|
- e.g., JUnit, custom tests, etc
|
||||||
|
|
||||||
|
## 7 Yaml
|
||||||
|
most Ci frameworks use YAML for their configuration
|
||||||
|
structured text based formats
|
||||||
|
- python-like format or ≈JSON
|
||||||
|
|
||||||
|
## 8 configurationg from git repo
|
||||||
|
CI config often via file in git top-level directory
|
||||||
|
- CI is version managed
|
||||||
|
|
||||||
|
Gitlab pipeling specs go into .gitlab-ci.yaml:
|
||||||
|
- shows command sequece to run for a jon, within a stage
|
||||||
|
- output from commands is stored for a subsequent viewing
|
||||||
|
- indicates what files 'artifacts' should be kept from jobs

# Debugging
|
||||||
|
removing technical faults
|
||||||
|
isolaing and remove technical faults
|
||||||
|
a human process
|
||||||
|
- requires creativity/disipline/knowledge
|
||||||
|
- deepr understanding of code
|
||||||
|
|
||||||
|
debuggers are tools to help debugging
|
||||||
|
|
||||||
|
## 1 common approaches
|
||||||
|
temporarily add output of diagnostic info
|
||||||
|
- "printf" debugging
|
||||||
|
permanently include calls to logging system
|
||||||
|
- route to terminal, log files etc
|
||||||
|
|
||||||
|
## 2 debugging machine code
|
||||||
|
- cpu runs code instruction by instruction
|
||||||
|
- thus debugger can intervene between instructions
|
||||||
|
- most cpus help debugger interrupt and resume programs
|
||||||
|
- cpu reached current code via a sequence on callers
|
||||||
|
- called **stack trace** , aka back frame, stack frame etc
|
||||||
|
- may reach point where it cannot continue
|
||||||
|
- e.g., integer division by zero, program execution must stop
|
||||||
|
- stack trace of stopped program can be analysed
|
||||||
|
|
||||||
|
## 3 Imperative languages
|
||||||
|
These are language that are executed in a step-wise, sequentail manner.
|
||||||
|
|
||||||
|
- debug symbols
|
||||||
|
- e.g., method named, variable named
|
||||||
|
- source code context
|
||||||
|
- line numbers
|
||||||
|
- variable name
|
||||||
|
- function method names
|
||||||
|
|
||||||
|
## 4 doing debugging
|
||||||
|
### 4.1 stepping skipping running
|
||||||
|
- step into --> steps one statement and steps into function calls
|
||||||
|
- step over --> a step that treats function calls as statement
|
||||||
|
- step out --> return to the instruction after the function call you're in
|
||||||
|
- continue --> go back to running code continuously
|
||||||
|
|
||||||
|
### 4.2 controlling debugger execution
|
||||||
|
Can run normally --> debugger wil run when program crashes
|
||||||
|
Set Breakpoint --> debugger will stop program when/if that line is reached
|
||||||
|
- conditional breakpoints only suspend if a condition is true
|
||||||
|
Watch point --> program is suspended when some data changes (e.g., variables)
|
||||||
|
|
||||||
|
## 5 debugging non imperative languages
|
||||||
|
e.g, spreadsheet (Dataflow programming)
|
||||||
|
- no breakpoints
|
||||||
|
- must step through _iterations of computations_
|
||||||
|
|
||||||
|
e.g., Equation
|
||||||
|
- break into smaller parts
|
||||||
|
- try 'compile' it in multiple ways
|
||||||
|
|
||||||
|
e.g., Data base query (declarative programming)
|
||||||
|
- -reexpressign the query and comaring can be useful

# 2 Dependencies among attributes
|
||||||
|
### 0.1 Functional Depenencies (FDs)
|
||||||
|
For any given value of attribute A there is _exactly one_ associated value of attribute B, then A _functionally determines_ B (loosely)
|
||||||
|
|
||||||
|
This is the theoretical basis for normalisation, and uniqueness property of PK (A is unique with respect to B)
|
||||||
|
|
||||||
|
- one to one
|
||||||
|
- Written as: A --> B
|
||||||
|
- Equivalently, "B is functionally dependent on A"
|
||||||
|
- Within a single relation only
|
||||||
|
- every attribute functionally dependent of primary key (PK)
|
||||||
|
|
||||||
|
#### 0.1.1 Example 1
|
||||||
|
- consdier a specific student ID e.g., 123346
|
||||||
|
- this student ID is alwasys associated witha single studnet name (e.g., jane smith)
|
||||||
|
- even it the students name changes, that student ID will still be asociated with the name of only that on student
|
||||||
|
- _The value of studnet id dtermines the value of student name_
|
||||||
|
|
||||||
|
#### 0.1.2 Other examples
|
||||||
|
- student ID --> student name (but not vice versa)
|
||||||
|
- car registration --> car owner (but not vice versa)
|
||||||
|
- rego --> VIN
|
||||||
|
- VIN --> rego
|
||||||
|
- student ID --> name, semester address, mobile number
|
||||||
|
- car rego --> owener name
|
||||||
|
- IRD number + year --> tax payable
|
||||||
|
- product ID + order no --> quantity ordered
|
||||||
|
|
||||||
|
#### 0.1.3 Anti examples
|
||||||
|
- student ID + name --> birth date (ovekill, partial dependency)
|
||||||
|
- home address --> student name
|
||||||
|
- name --> birth date
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### 0.2 Using Functional dependencies
|
||||||
|
To determine them:
|
||||||
|
- need detailed knowledge of thebusiness rules
|
||||||
|
- examine existing data sets
|
||||||
|
- not always practical when these are large or unknown
|
||||||
|
|
||||||
|
Can be represented using funcitonal dependency diagrams (FDDs)
|
||||||
|
|
||||||
|
Bottom up approach
|
||||||
|
- ERD is "top-down"
|
||||||
|
- FD best used as a design validation tool
|
||||||
|
|
||||||
|
### 0.3 Types of functional dependencies
|
||||||
|
#### 0.3.1 Dependencies on more that one attribute
|
||||||
|
non primary attributes that are dependent on two or more attributes
|
||||||
|
always arise with composite PKs
|
||||||
|
e.g.,
|
||||||
|
|
||||||
|
|
||||||
|
#### 0.3.2 Partial Dependency
|
||||||
|
Subset of left hand side determines right hand side
|
||||||
|
"extra attributes"
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
|
||||||
|
![Uploading file...mfewm]()
|
||||||
|
|
||||||
|
#### 0.3.3 Transitive dependency
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- part num determines supplier number
|
||||||
|
- supplier number determines supplier name
|
||||||
|
- part number determines supplier name
|
||||||
|
|
||||||
|
BUT 3 is already implied by 1 & 2 --> redundant supplier names
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### 0.4 Multivalued dependencies (MVDs)
|
||||||
|
if for any given value of attribute A there is a _set_ of associated values of attribute S, the a _Multidetermines_ S (loosely)
|
||||||
|
|
||||||
|
- one to many
|
||||||
|
- written: A ↠ S
|
||||||
|
- equivalently, "S is multiply dependent on A"
|
||||||
|
- Generalistion of FDs: all FDs are MVDs, but not vice versa
|
||||||
|
- A is still unique with respect to S
|
||||||
|
|
||||||
|

||||||
|
#### 2.3.2 Partial Dependency
|
||||||
|
Subset of left hand side determines right hand side
|
||||||
|
"extra attributes"
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
|
||||||
|
![Uploading file...mfewm]()
|
||||||
|
|
||||||
|
#### 2.3.3 Transitive dependency
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- part num determines supplier number
|
||||||
|
- supplier number determines supplier name
|
||||||
|
- part number determines supplier name
|
||||||
|
|
||||||
|
BUT 3 is already implied by 1 & 2 --> redundant supplier names
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### 2.4 Multivalued dependencies (MVDs)
|
||||||
|
if for any given value of attribute A there is a _set_ of associated values of attribute S, the a _Multidetermines_ S (loosely)
|
||||||
|
|
||||||
|
- one to many
|
||||||
|
- written: A ↠ S
|
||||||
|
- equivalently, "S is multiply dependent on A"
|
||||||
|
- Generalistion of FDs: all FDs are MVDs, but not vice versa
|
||||||
|
- A is still unique with respect to S
|
||||||
|
|
||||||

# Documentation
|
||||||
|
## 1 Who, what where
|
||||||
|
- Audience
|
||||||
|
- users
|
||||||
|
- other devs
|
||||||
|
- your team members
|
||||||
|
- anyone trying to understand you software
|
||||||
|
- your future self
|
||||||
|
- Locations
|
||||||
|
- source code
|
||||||
|
- project repo
|
||||||
|
- emebedding in program
|
||||||
|
- hosted separately
|
||||||
|
- User expectations
|
||||||
|
- evolving towards software that _facilitates experimentation_
|
||||||
|
- No help docs => everything is self-explanatory
|
||||||
|
- high usability
|
||||||
|
- users familar with many abstractions
|
||||||
|
- e.g., touchscreens, menus, links
|
||||||
|
- API's
|
||||||
|
- for devs writing code to interact with your code
|
||||||
|
- typically coupled with docs
|
||||||
|
- entirely technical audience --> tool generated docs are okay
|
||||||
|
- not self explanatory
|
||||||
|
- used by devs unfamiliar with code base
|
||||||
|
- Project Docs
|
||||||
|
- meaningful commit msgs
|
||||||
|
- extra mangement with e.g., github
|
||||||
|
- issue tracking
|
||||||
|
- ensures relevant material is cross linked where possible
|
||||||
|
- can easily refer to source code
|
||||||
|
- Source code docs
|
||||||
|
- header comments
|
||||||
|
- software licencing
|
||||||
|
- support devs
|
||||||
|
- indicate code ownership
|
||||||
|
- in code comments on fields methods etc
|
||||||
|
- keep in sync with code changes
|
||||||
|
- descriptive variable/class/other names
|
||||||
|
|
||||||
|
## 2 Built in language support
|
||||||
|
- basic
|
||||||
|
- syntax for code comments
|
||||||
|
- indicate that the compiler should ingnore
|
||||||
|
- also more advanced like python "doc strings"
|
||||||
|
- Structured comments and docs
|
||||||
|
- machine parseable comments
|
||||||
|
- e.g., javadocs, perl plain old docs
|
||||||
|
- creates a doc website
|
||||||
|
- uses annotations e.g., @author, @returns, @param
|
||||||
|
- Literate programming
|
||||||
|
- donald knuth suggestions (1984)
|
||||||
|
- source code should be primarily natural language documentation
|
||||||
|
- executable code snippetrs are included within the description
|
||||||
|
- tools are used to:
|
||||||
|
- tangle the code snippets
|
||||||
|
- weave out the documentation
|
||||||
|
- Modern implementations
|
||||||
|
- jupyter notebooks
|
||||||
|
- swift playgrounds
|
||||||
|
- r markdown

# Domain Driven Design
|
||||||
|
|
||||||
|
>A method of designing software by designing models of the domain and creating software which conforms to those models
|
||||||
|
|
||||||
|
Ubiquitous language -> The language a team agrees on to describe ideas in the problem domain
|
||||||
|
- This laguage becomes more and more refined as it is used
|
||||||
|
- This reduces misunderstandings

# Entity Relationship Diagrams
|
||||||
|
|
||||||
|
|
||||||
|
cardinality
|
||||||
|
identifying vs non identifying relationship
|
||||||
|
|
||||||
|
labels are important - but not always needed
|
||||||
|
|
||||||
|
associative entity => changes many to many relationship with additional relationship
|
||||||
|
|
||||||
|
## 1 subtypes
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
uses:
|
||||||
|
- model mutual exclusivity
|
||||||
|
- better for modelling not for implementation
|
||||||
|
|
||||||
|
## 2 parallel relationship
|
||||||
|
|
||||||
|
|
||||||
|
could model as separate relationships via staff subtypes
|
||||||
|
not very common
|
||||||
|
|
||||||
|
|
||||||
|
also an example of recursive many-to-many relationships
|
||||||
|
|
||||||
|
## 3 recursive relationship
|
||||||
|
labels are critical
|
||||||
|
usually 1:M can be 1:1 or M:M
|
||||||
|
|
||||||
|
|
||||||
|
## 4 dealing with data history
|
||||||
|
|
||||||
|
|
||||||
|
could be many to many relationships:
|
||||||
|
|
||||||
|
so associative relationship: 
|
||||||
|
|
||||||
|
|
||||||
|
what do we require:
|
||||||
|
- for the current point in time
|
||||||
|
- an histroical record how ⇒ must be selecetive to not use up to much space

# Ethics
|
||||||
|
## 1 Case studies
|
||||||
|
1. [facial recognition in US riots 2021-01-06](content/notes/facial-recognition-in-us-riots-2021-01-06.md)
|
||||||
|
2. [Anti govt protest china](content/notes/anti-govt-protest-china.md)
|
||||||
|
3. [How is safe enough for autonomous vehicles](content/notes/how-is-safe-enough-for-autonomous-vehicles.md)
|
||||||
|
|
||||||
|
### 1.1 Differences 1 vs 2
|
||||||
|
Govt vs vigilante
|
||||||
|
|
||||||
|
my judgements contain additionl context
|
||||||
|
e.g., pro-democratic vs anti
|
||||||
|
|
||||||
|
world contains vast differences
|
||||||
|
how systems of laws work
|
||||||
|
extent of civil liberties afforded to individuals
|
||||||
|
|
||||||
|
### 1.2 Discussion
|
||||||
|
When developing a technology you dont know what is could be used for
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 2 Ethical handling of data
|
||||||
|
- Data moves very quickly due to computerised systems
|
||||||
|
- privacy act 2020
|
||||||
|
- its unethical to ignore potential security problems
|
||||||
|
- df
|
||||||
|
|
||||||
|
## 3 Ethical handling of bias and errors, e.g., in AI
|
||||||
|
- large datasets oftenb incdlude bias and errors
|
||||||
|
- to AI trained on these datasets with also be biased
|
||||||
|
- e.g., facial recognition trining overrepresenting white males
|
||||||
|
- ML algorithgms are often opqaue
|
||||||
|
- its not possible to understand how decisions are reached
|
||||||
|
- makes asessing suitability of AI for a use case difficult
|
||||||
|
- explainable AI
|
||||||
|
- attacks e.g., 'trapdoors' within ML training data
|
||||||
|
|
||||||
|
## 4 False or misleading claims
|
||||||
|
- pressure to release can lead to false claims
|
||||||
|
- are features fully tested
|
||||||
|
- need to assess risks of bias
|
||||||
|
- e.g., AWS uptime information
|
||||||
|
- rumoured that service status colour is n management decision
|
||||||
|
-
|
||||||
|
|
||||||
|
## 5 Your responsibility
|
||||||
|
- dont stay silent
|
||||||
|
|
||||||
|
## 6 Professional reponsibilities
|
||||||
|
- comp science per se lacks profressional standards
|
||||||
|
- there are some prefessional bodies which encoede responsibilities
|
||||||
|
- ACM coc
|
||||||
|
- IEEE coc
|
||||||
|
- neither are specific to NZ
|
||||||
|
- Within NZ must consider treaty obligations

#### Review questions
|
||||||
|
1. what are two of the five (PGRCW) isses to consider when evaluating designs
|
||||||
|
- precision and reliability
|
||||||
|
- are your evaulationg repeatable
|
||||||
|
- are they accurate
|
||||||
|
- generalizability
|
||||||
|
- do your findings apply to the real world
|
||||||
|
- realism
|
||||||
|
- do you results apply tot he real world
|
||||||
|
- comparison
|
||||||
|
- better than just "do you like it study"
|
||||||
|
|
||||||
|
3. what are the two styles of evaluation. How do they differ
|
||||||
|
- ~~qualitative and quantitative~~
|
||||||
|
- field and lab studies
|
||||||
|
|
||||||
|
4. when would you use a qualitative methods and when would you use a quantitative method
|
||||||
|
- qualitative when comparing designs
|
||||||
|
- quantitative when evaluating a single design
|
||||||
|
|
||||||
|
5. what are two stages of design and in each cycle which type of method should you use
|
||||||
|
- design stage qualitative
|
||||||
|
- implentation quantitative
|
||||||
|
|
||||||
|
6. give a brief description of one method of evaluation.
|
||||||
|
- feedback from experts
|
||||||
|
- usbility studies
|
||||||
|
- observation
|
||||||
|
- simulation/maths
|
||||||
|
- surveys/focus groups
|
||||||
|
- comparitive experiments

# Evaluating-designs
|
||||||
|
Why to evaluate using 'outside' people:
|
||||||
|
- how do we know if a [prototype](content/notes/prototyping.md) is good
|
||||||
|
- designer/developers are not 'fresh' -> they already have experience with the product
|
||||||
|
- designer/developers don't know what real users will do
|
||||||
|
|
||||||
|
## Issues to consider
|
||||||
|
- Reliability/precision
|
||||||
|
- how accurate is your study?
|
||||||
|
- Is is reproducible -> if it was repeated, would you get the same result
|
||||||
|
- Generalizability
|
||||||
|
- Is your sample representative
|
||||||
|
- Realism
|
||||||
|
- Would observed behaviour also occur in the wild
|
||||||
|
- Comparison
|
||||||
|
- Shows how different options were recieved
|
||||||
|
- rather than a "people liked it" study
|
||||||
|
- work involved/efficiency
|
||||||
|
- How cost efficient are your methods
|
||||||
|
|
||||||
|
## Factors to consider when choosing an evaluation method
|
||||||
|
- Stage in the cycle at which the evaluation is carried out -> (design / implementation)
|
||||||
|
- Style of evaluation -> (lab / field)
|
||||||
|
- Level of subjectivity or objectivity
|
||||||
|
- Type of measurement -> (qualitative / quantitative)
|
||||||
|
- Information provided -> (high-level / low-level)
|
||||||
|
- Immediacy of response -> (real-time / recollection of events)
|
||||||
|
- Level of interference implied -> (intrusiveness)
|
||||||
|
- Resources required -> (equipment, time, money, subjects, expertise, context)
|
||||||
|
|
||||||
|
## Styles of evaluation
|
||||||
|
##### Laboratory Studies
|
||||||
|
- 1st step: Designer evaluates his/her UI
|
||||||
|
- Specialised equipment for testing available
|
||||||
|
- Undisturbed (can be a good or bad thing)
|
||||||
|
- Allows for well controlled experiments
|
||||||
|
- Substitute for dangerous or remote real-world locations
|
||||||
|
- Variations in manipulations possible / alternatives
|
||||||
|
|
||||||
|
##### Field Studies
|
||||||
|
- Within the actual user’s working environment
|
||||||
|
- Observe the system in action
|
||||||
|
- Disturbance / interruptions (+/-)
|
||||||
|
- Long-term studies possible
|
||||||
|
- Bias: presence of observer and equipment
|
||||||
|
- Needs support / disturbs real workflow
|
||||||
|
|
||||||
|
## Quantitative vs Qualitative methods
|
||||||
|
##### Quantitative Measures
|
||||||
|
- Usually numeric
|
||||||
|
- E.g. # of errors, time to complete a certain task, questionnaire with scales
|
||||||
|
- Can be (easily) analysed using statistical techniques
|
||||||
|
- Rather objective
|
||||||
|
- Most useful in comparing alternative designs
|
||||||
|
- Test hypotheses
|
||||||
|
- Confirm designs
|
||||||
|
|
||||||
|
##### Qualitative Measures
|
||||||
|
- Non-numeric
|
||||||
|
- E.g. survey, interview, informal observation, heuristic evaluation
|
||||||
|
- Difficult to analyse, demands interpretation
|
||||||
|
- Rather subjective
|
||||||
|
- User’s overall reaction and understanding of design
|
||||||
|
- Generate hypotheses
|
||||||
|
- Find flaws
|
||||||
|
|
||||||
|
## Stage in cycle
|
||||||
|
##### Design Stage
|
||||||
|
- Only concept (even if very detailed) exists
|
||||||
|
- More experts, less users involved
|
||||||
|
- Greatest pay-off: early error detection saves a lot of development money
|
||||||
|
- Rather qualitative measures (exceptions: detail alternatives; fundamental questions, ...)
|
||||||
|
|
||||||
|
##### Implementation
|
||||||
|
- Artefact exists, sth. concrete to be tested
|
||||||
|
- More users, less experts involved
|
||||||
|
- Assures quality of product before or after deployment; bug detection
|
||||||
|
- Rather quantitative measures (exceptions: overall satisfaction, appeal, ...)
|
||||||
|
|
||||||
|
## Methods
|
||||||
|
### Usability studies
|
||||||
|
- Bringing people in to test Product
|
||||||
|
- Usage setting is not ecologically valid - usage in real world can be different
|
||||||
|
- can have tester bias - testers are not the same as real users
|
||||||
|
- cant compare interfaces
|
||||||
|
- requires physical contact
|
||||||
|
### Surveys and focus groups
|
||||||
|
+ quicly get feedback from large number of responses
|
||||||
|
+ auto tally ressults
|
||||||
|
+ easy to compare different products
|
||||||
|
- responder bias
|
||||||
|
- Not accurate representation of real product
|
||||||
|
* e.g., 
|
||||||
|
* Focus groups
|
||||||
|
* gathering groups of people to discuss an interface
|
||||||
|
* group setting can help or hinder
|
||||||
|
|
||||||
|
### Feedback from experts
|
||||||
|
- [Peer critique](None)
|
||||||
|
- [Dogfooding](None)
|
||||||
|
- Using tools yourself
|
||||||
|
- [Heuristic Evaluation](content/notes/heuristic-evaluation.md)
|
||||||
|
- structured feedback
|
||||||
|
|
||||||
|
### Comparative experiments
|
||||||
|
- in lab, field, online
|
||||||
|
- short or long duration
|
||||||
|
- which option is better?
|
||||||
|
- what matters most?
|
||||||
|
- can see real usage
|
||||||
|
- more actionable
|
||||||
|
|
||||||
|
### Participant observation
|
||||||
|
- observe what people do in the actual evironment
|
||||||
|
- usually more long term
|
||||||
|
- find things not present in short term studies
|
||||||
|
- [Observation](content/notes/observation.md)
|
||||||
|
|
||||||
|
### Simulation and formal models
|
||||||
|
- more mathmatical quantitative
|
||||||
|
- useful if you have a theory to test
|
||||||
|
- often used for input techniques
|
||||||
|
- can test multiple alternatives quickly
|
||||||
|
- typically simulation is used in conjugtion with [monte carlo optimisation](None)
|
||||||
|
|
||||||
|
## Query techniques
|
||||||
|
- [Interviews](content/notes/interviews.md)
|
||||||
|
- questionnaires
|
||||||
|
- less flexible
|
||||||
|
- larger samples possible
|
||||||
|
- design of questionnaire is for expert only
|
||||||
|
- use of standard (proven) questionnaires recommended
|
||||||
|
- types of questions:
|
||||||
|
- general (age, gender)
|
||||||
|
- open ended
|
||||||
|
- scalar (e.g., likert-like scales)
|
||||||
|
- multiple choice
|
||||||
|
- ranking
|
||||||
|
|
||||||
|
## Users
|
||||||
|
- users can come up with great ideas
|
||||||
|
- lead user -> need specific soluton that does not exist -> often make up their own solution
|
||||||
|
- extreme user -> use existing solution for it's intended purpose to an extreme degree
|
||||||
|
- typical user ->

# Extreme programming (XP)
|
||||||
|
|
||||||
|
^e9fd09
|
||||||
|
|
||||||
|
take current industry practices to the extreme
|
||||||
|
- focus of proven industry practices
|
||||||
|
- combine them innovatively to get better results
|
||||||
|
|
||||||
|
##### Values and principles
|
||||||
|
communication, simplicity, feedback, courage.
|
||||||
|
- Planning -> based on user stories
|
||||||
|
- Testing -> thorough testing at every step
|
||||||
|
- Pair programming -> watch, inspect, and trade off
|
||||||
|
- Simple designs -> based on agile modelling principles
|
||||||
|
- Refactoring -> redo and clean up as you go
|
||||||
|
- Collective code ownership -> egoless development, anyone can review and improve code
|
||||||
|
- Continuous integration -> grow the software continuously
|
||||||
|
- On-site customer -> get sign-off as you go
|
||||||
|
- System metaphor -> what should the final system look like? Small releases given to users frequently
|
||||||
|
- Forty-hour work week -> don’t overload the developers
|
||||||
|
- Coding standards -> follow industry standards for code
|
||||||
|
|
||||||
|
##### Three ring project approach

# Capital riots face recognition
|
||||||
|
capital riots occured on 2021-01-06
|
||||||
|
|
||||||
|
there was video from the riots which contained faces
|
||||||
|
- facial recognition acquired a pic of each person
|
||||||
|
- faces were uploaded to a website

# Video prototyping
|
||||||
|
|
||||||
|
## 1 benefits
|
||||||
|
- cheap and fast
|
||||||
|
- great communication
|
||||||
|
- can serve as spec for devs
|
||||||
|
- ties interface design to tasks
|
||||||
|
|
||||||
|
## 2 fidelity
|
||||||
|
low-fi 2-5min brainstorm
|
||||||
|
mid-fi 1-4 paper prtotypes video
|
||||||
|
hi-fi slick +fancy for investors/management
|
||||||
|
|
||||||
|
## 3 shows
|
||||||
|
- like a storyboard, the whole tasks
|
||||||
|
- motivvationa and success
|
||||||
|
- draw on tasks you've observed
|
||||||
|
- illustrate importand tasks
|
||||||
|
- help scope minimum viable poduct
|
||||||
|
- forces you to make design decisions in a new way
|
||||||
|
|
||||||
|
## 4 steps
|
||||||
|
- outline (maybe use storyboards)
|
||||||
|
- fin to extemporize
|
||||||
|
- equiment
|
||||||
|
- a camera (not fancy needed)
|
||||||
|
- people
|
||||||
|
- realistic location
|
||||||
|
- focus on the message more than production values
|
||||||
|
|
||||||
|
## 5 considerations
|
||||||
|
- silent(with title cards) or with audio
|
||||||
|
- audio can be finicky
|
||||||
|
- interface can be anything
|
||||||
|
- mockups, paper prototypes, code
|
||||||
|
- can show success and failure of interfaces an failure
|
||||||
|
- edit as little as possible (time consuming)

# Faking it Wizard of OZ
|
||||||
|
|
||||||
|
making interactive app quickly with minimal code
|
||||||
|
|
||||||
|
simulate interactive behaviour with human operators
|
||||||
|
|
||||||
|
- make interactive app without much code
|
||||||
|
- front end interface
|
||||||
|
- remote wizard controls user interface
|
||||||
|
- makes sense with is faster/cheaper/easier than making the real thing
|
||||||
|
- get feedback from users people
|
||||||
|
- hi-fi users think its more real
|
||||||
|
- low-fi: more license to suggest changes
|
||||||
|
|
||||||
|
## 1 making wizard protoypes
|
||||||
|
- find scenarios to protoypes
|
||||||
|
- create UI skeleton
|
||||||
|
- develop hooks for wizard input
|
||||||
|
- decide where and how the wizard will provide input
|
||||||
|
- remember not to fake stuff that it not feasible in real life
|
||||||
|
- rehearse wizard rile with colleague
|
||||||
|
|
||||||
|
## 2 running wizard protoypes
|
||||||
|
- practivce with friend
|
||||||
|
- recruit users
|
||||||
|
|
||||||
|
- two roles:
|
||||||
|
- facilitator ⇒ pprovides tasks and takes notes
|
||||||
|
- wizard ⇒ operaties interface
|
||||||
|
|
||||||
|
- user feedback
|
||||||
|
- think aloud
|
||||||
|
- retrospective
|
||||||
|
- heuristic evaluation
|
||||||
|
|
||||||
|
- debrief users
|
||||||
|
|
||||||
|
|
||||||
|
## 3 used throughout development
|
||||||
|
user can do less and less and the prototyp comes closer to realisation
|
||||||
|
|
||||||
|
## 4 advatages
|
||||||
|
- fast
|
||||||
|
- variable
|
||||||
|
- more real than papar prototypes
|
||||||
|
- finds bugs and pronlems with design
|
||||||
|
- places user at center
|
||||||
|
- can envision challenging to built application
|
||||||
|
- ability to look foward and "use" tech that isn't created yet
|
||||||
|
|
||||||
|
|
||||||
|
## 5 Disadvatages
|
||||||
|
- simulations may misrepresent otherwire imperfect tech
|
||||||
|
- mya simulate techs that not not exist (and mnay never)
|
||||||
|
- require training and can be inconsistent
|
||||||
|
- playing the wizard can be exhausting
|
||||||
|
- some features are difficult to simulate
|
||||||
|
- may not be appropriate

# Git Cheat Sheet
|
||||||
|
#### 0.1.1 Commands
|
||||||
|
|
||||||
|
- Clone -> create local copy of remote repo
|
||||||
|
- Commit -> save changes to local repo
|
||||||
|
- Packages logically related collection of changes and save the permanently is repos history
|
||||||
|
- Each commit should address single well defined task
|
||||||
|
- Commits should be small and regular
|
||||||
|
- Should contain a brief, informative, message
|
||||||
|
- one line -> <50 (commit needing more than this are likely too large)
|
||||||
|
- multi line -> <72
|
||||||
|
- well defined, shared terminology
|
||||||
|
- consider what other devs need to know
|
||||||
|
- Stash -> temporarily store uncommited changes
|
||||||
|
- Push -> Upload changes from local repo to remote
|
||||||
|
- Pull -> Download and merge changes from remote repo into local repo (fetch + merge)
|
||||||
|
- Merge -> Merge changes from one brach into another
|
||||||
|
- merge when:
|
||||||
|
- pulling changes from remote into your repo
|
||||||
|
- merging from branch into main codebase
|
||||||
|
- Can merge any branch into any other branch
|
||||||
|
- good idea to regularly rebase specialised persistent branches to keep them in sync with the more general main codebase
|
||||||
|
- rebase topic branches before merging into main
|
||||||
|
- helps to deal with merge conflicts
|
||||||
|
- only branch is broken if you mess up
|
||||||
|
- can test for breakage before merging to main
|
||||||
|
- Merging is usually automatic
|
||||||
|
- sometimes merge algorithm can't resolve conflicting changes to the same code
|
||||||
|
- e.g., two devs change the same method at the same time
|
||||||
|
- conflict must then be manually resolved
|
||||||
|
- All VCS will check that your repo is up to date before pushing, and force you to push if not
|
||||||
|
- Tag -> name a particular commit e.g., for a release
|
||||||
|
|
||||||
|
#### 0.1.2 Terms
|
||||||
|
- Head -> most recent commit on Current branch
|
||||||
|
-[Branch](content/notes/branch.md) -> Split current dev path into two to work on e.g., a bug or a feature
|
||||||
|
- Repository -> Where the codebase/file are stored ^3b3a5d
|
||||||
|
- Contains meta-data about the previous vesions etc
|
||||||
|
- Merge commit -> commits which are derived from multiple parent commits
|
||||||
|
- Git tag -> e.g., v 1.0
|
||||||
|
- cannot be move by commits
|
||||||
|
- record metadata

# Git
|
||||||
|
Git is a tool to track changes to sets of files
|
||||||
|
It is the most used [[Version Control Systems|VCS]
|
||||||
|
|
||||||
|
## Team git protocols
|
||||||
|
you can develop a team protocol for Git use
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- agree to commit often
|
||||||
|
- know what branches are being used and why
|
||||||
|
- consider pair programming / live sharing
|
||||||
|
- try not to touch lots of files without signalling why
|
||||||
|
- agree who's going to edit files that maight not auto merge
|
||||||
|
|
||||||
|
## web based repo access control
|
||||||
|
owner of repo chooses who can push to project
|
||||||
|
- maintainer -> cant remove data
|
||||||
|
- developer -> cant manage team
|
||||||
|
- reporter -> cant change codebase
|
||||||
|
- guest -> can view
|
||||||
|
|
||||||
|
### open source collaboration
|
||||||
|
you want contributions from everyone
|
||||||
|
but you dont want to manage user-level control
|
||||||
|
|
||||||
|
-> pull/merge requests
|
||||||
|
unknown users can fork then add a feature/bug then do a merge request which can be reviewed
|
||||||
|
|
||||||
|
## git repos
|
||||||
|
[Repositories](content/notes/git-cheat-sheet.md#^3b3a5d) maintain code history
|
||||||
|
can be conceptualised as a graph
|
||||||
|
```mermaid
|
||||||
|
graph RL
|
||||||
|
A[HEAD]-->1[MASTER]-->B((ab348b))-->C((hf33h3))
|
||||||
|
C-->D((3hh39h))
|
||||||
|
C-.Merge.->E((n3383b))
|
||||||
|
3[Branch]-->E
|
||||||
|
D-->H((kfj383))
|
||||||
|
E-->G((gj4jf4))
|
||||||
|
G-->H
|
||||||
|
H-->I((fjfj39))
|
||||||
|
I-->2[Inital Commit]
|
||||||
|
```
|
||||||
|
```mermaid
|
||||||
|
gitGraph:
|
||||||
|
checkout master
|
||||||
|
commit
|
||||||
|
commit
|
||||||
|
branch newbranch
|
||||||
|
checkout newbranch
|
||||||
|
commit
|
||||||
|
commit
|
||||||
|
checkout master
|
||||||
|
commit
|
||||||
|
merge newbranch
|
||||||
|
commit
|
||||||
|
commit
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
- nodes are commits -> immutable snapshots of the tracked files
|
||||||
|
- edges record how nodes emerged over time
|
||||||
|
- arrows can be read as "is derived from"
|
||||||
|
|
||||||
|
git is a [Decentralised and Centralised VCS](content/notes/version-control-systems.md#^98d838)
|
||||||
|
- every team members has their own local copy of the repo
|
||||||
|
- git repos are often syned with a server: github, gitlab,etc
|
||||||
|
|
||||||
|
## levels of complexity/Abstraction
|
||||||
|
```mermaid
|
||||||
|
graph TD
|
||||||
|
w(github gitlab from web browser)-->b(graphical ide's e.g., vscode)-->c(command line git)-->d(low level git plumbing commands)-->e(direct manipulation of records within repo's .git directory)
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
## Limitations/pain points
|
||||||
|
not designed for broad usability
|
||||||
|
- bottom up design stems from its implementaion,
|
||||||
|
- rather than top down design from user interface
|
||||||
|
- thus, command naming and syntax can be unintuitive
|
||||||
|
|
||||||
|
git is not suited to handling large data files
|
||||||
|
- git scans whole files to generate hash codes
|
||||||
|
- can use git lfs (large file support) to get around this
|
||||||
|
|
||||||
|
flexibility of git can lead to high cognitive load
|
||||||
|
- e.g., many ways to get others' commits to your repo
|
||||||
|
|
||||||
|
binary files e.g., JPEG images are treated as whole
|
||||||
|
- no differencing, no content merging
|
||||||
|
|
||||||
|
some text files may not have stable line structure
|
||||||
|
- e.g., XML data can be reordered wihout changing so:
|
||||||
|
- git can auto merge when this is destructive
|
||||||
|
- git may get confused and force you to merge
|
||||||
|
- e.g., node package-lock.json
|
||||||
|
- you can turn of auto-merge if you are working with files that may be problematic
|
||||||
|
|
||||||
|
## advantages
|
||||||
|
git repos' data structures are well designed
|
||||||
|
- clear in structure yet flexible and efficient
|
||||||
|
|
||||||
|
few dependencies
|
||||||
|
- widely available
|
||||||
|
- free and open source
|
||||||
|
|
||||||
|
community support around use of git is great
|
||||||
|
- eforts to get researches to use version control;
|
||||||
|
- github helped open source software flourish by making it easy for citizens to contribute to projects

**Focus on people**
|
||||||
|
|
||||||
|
Good design is good
|
||||||
|
Bad design costs lives, money, time
|
||||||
|
Bad design can be easily avoided using basic ideas like consistency and feedback

# Heap
|
||||||
|
A tree
|
||||||
|
1. every elements should be greater than ites children
|
||||||
|
2. the structure should be filled from top to bottom and left to right
|
||||||
|
|
||||||
|
To remove
|
||||||
|
- remove from the top, replace with the last element
|
||||||
|
- to fix the first condition swap the top element with the highest of its children until fixed
|
||||||
|
|
||||||
|
To Add
|
||||||
|
- add to the next position
|
||||||
|
- If its larger than its parent then swap them
|
||||||
|
|
||||||
|
How deep
|
||||||
|
- each layer is twice as deep and the preceding one
|
||||||
|
- layer k can hold $2^k$ elements
|
||||||
|
- to store n elements we use k layers where $k = lg n$
|
||||||
|
- so we need ϴ(lg n) layers
|
||||||
|
- So any algorithm that 'walk along a branch' in while or in part will have Ο(n) complexity (assuming constant time work at each node)

# Heuristic evaluation
|

|
>"Heuristics are strategies derived from previous experiences with similar problems"
|
||||||
|
jacob nielsen and rolf molich
|
||||||
|
|
||||||
|
help find usability problems
|
||||||
|
small set of 3-5 evaluators examine UI
|
||||||
|
independently check for compliance with usability principles
|
||||||
|
different evaluators will find different problems
|
||||||
|
evaluators only communicate afterwaards
|
||||||
|
findings are aggregated at the end
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 1 when?
|
||||||
|
- as part of need finding -> use experts to critique existing solutions
|
||||||
|
- before user testing -> identify minor issues before user testing
|
||||||
|
- before redesigning -> learn what works and what should change
|
||||||
|
- when you know there are problems but you need evidence -> "provide you with ammunition for design"
|
||||||
|
- before release -> smooth off rough edges
|
||||||
|
|
||||||
|

#### 2.1.1 Overview
|
||||||
|
Helps find problems in design
|
||||||
|
- 3-4 evaluators examine UI
|
||||||
|
- independent reviewers check for compliance with usability principles
|
||||||
|
- each evaluator will find different problems
|
||||||
|
- evaluators only communicate afterwards and the findings are aggregated
|
||||||
|
can perform on working UI or sketches
|
||||||
|
|
||||||
|
#### 2.1.2 Phases
|
||||||
|
1. pre evaluation training ⇒ give evaluators needed domain knowledge and information on the scenario
|
||||||
|
2. evaluation ⇒ individuals evaluate then aggregate result
|
||||||
|
1. first as individuals
|
||||||
|
2. then sit all together and aggregate
|
||||||
|
3. Severity rating ⇒ determine how severe each problem is (priority). Can do first individually and then as a group
|
||||||
|
4. Debriefing ⇒ review with design team
|
||||||
|
|
||||||
|
#### 2.1.3 Individual
|
||||||
|
dont look search for heuristics individually
|
||||||
|
just go through the app (like a user). If we find issues, we assign them to categories
|
||||||
|
|
||||||
|
step through design several times
|
||||||
|
- examine details, flow, an architecture
|
||||||
|
- consult list of usability principles
|
||||||
|
- … and anything else that comes to mind
|
||||||
|
|
||||||
|
which principles
|
||||||
|
- Nielsen's heuristics
|
||||||
|
- category specific heuristics
|
||||||
|
- e.g., design goals, competitive analysis, existing designs
|
||||||
|
|
||||||
|
use violations for redesign/fix problems
|
||||||
|
|
||||||
|
multiple evaluators because no one finds everything
|
||||||
|
some will always find more than others (Rule of thumb 5 evaluators find ~75% of problems)
|
||||||
|
|
||||||
|
#### 2.1.4 Severity rating
|
||||||
|
- independently estimate after viewing
|
||||||
|
- allocate resources to fix problems
|
||||||
|
- estimate need for more usability tests
|
||||||
|
|
||||||
|
0. not problem
|
||||||
|
1. cosmetic problem
|
||||||
|
2. minor usability problem
|
||||||
|
3. major
|
||||||
|
4. catastrophe
|
||||||
|
|
||||||
|
#### 2.1.5 Debreifing
|
||||||
|
- with evaluators observers and dev team
|
||||||
|
- discuss general characteristics of UI
|
||||||
|
- suggest potential imporvements
|
||||||
|
- dev team estimate effort to fix
|
||||||
|
- brainstorm solutions
|
||||||
|
|
||||||
|
### 2.2 Nielsen's ten heuristics
|
||||||
|
visibility of system status
|
||||||
|
match between system and world
|
||||||
|
user control and freedom
|
||||||
|
consistency and standards
|
||||||
|
error prevention
|
||||||
|
recognition rather than recall
|
||||||
|
flexibility and efficiency of use
|
||||||
|
aesthetic and minimalist design
|
||||||
|
help users recognize, diagnose, and recover from errors
|
||||||
|
help and documentation
|
||||||
|
|
||||||
|
### 2.3 Heuristic evaluation vs user testting
|
||||||
|
|
||||||
|
heuristics | user testing
|
||||||
|
----------------- | --------------
|
||||||
|
faster | slower
|
||||||
|
1-2 hrs each |
|
||||||
|

|
||||||
|
^ done by experts |
|
||||||
|
less accurate | more acurate
|
||||||
|
does not take into account actual users | can find issues that experts might not have
|
||||||
|
value to alternate methods
|
||||||
|
^ find dfferent issues

||||||
|
### 2.4 Extra tips how to individual
|
||||||
|
- at least two passes each
|
||||||
|
- first get get feel for flow
|
||||||
|
- second to focus on specific elements
|
||||||
|
- if a system is "walk up and use" or evaluators are already domain expers ⇒ no assistance is needed
|
||||||
|
- otherwire might supply evaluators with scenarios
|
||||||
|
- each evaluators should list issues separately
|
||||||
|
- risk of repeating problematic aspect
|
||||||
|
- may not be possible to fix all problems
|
||||||
|
- where problems may be found
|
||||||
|
- single location in UI
|
||||||
|
- two or more locations that need to be compared
|
||||||
|
- problem with overall structure
|
||||||
|
- something is missing
|
||||||
|
- ambiguous with early prototypes
|
||||||
|
- sometimes ....

## 1 Abstract
|
||||||
|
The purpose of this evaluation was to uncover existing usability and functionality issues with the Skype app, so that it's usabilty can be improved. Heuristic Evaluations were carried out by three individuals according to Jakob Nielsen's ten design heuristics and a severity scale of 0 (not an issue) to 4 (usability catastrophe).
|
||||||
|
|
||||||
|
Their tasks were to set up and carry out a meeting using the app, and to look out for violations of Neilsens ten heuristics.
|
||||||
|
|
||||||
|
The key findings of this evaluation revealed that while the app is mostly usable, there are a few major issues that need to be fixed.
|
||||||
|
|
||||||
|
## 2 Executive summary
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
The skype app is one of the most used online messaging and video call desktop applications. It allows users to "make free video and one-to-one and group calls, send instant messges and share files with other people on Skype" (_What Is Skype? | Skype Support_, n.d.).
|
||||||
|
|
||||||
|
In order to set up a meeting the user needed to press the Meet now button which is visible in many places. To add more participants the use can either call a group chat directly, or share a link to the meeting.
|
||||||
|
|
||||||
|
In addition to many minor issues, the evaluators were able to find multiple major usability issues within the app. The three most severe issues were:
|
||||||
|
|
||||||
|
**Finding 1: Visibility of system status** The windows OS close window button clooses skype without leaving the meeting. It opens the small floating window. This is not so bad, however, when the user closes the floating window, the user does still not leave the meeting, and is still visible to other users while having no indicator whatsoever that they are still in a call. This is a major issues as it is a privacy concern for the user.
|
||||||
|
|
||||||
|
It is reccomended that when closing the main window using the windows OS close button, the user should be prompted to leave the meeting.
|
||||||
|
|
||||||
|
**Finding 2: Error prevention and Visibility of system status** When Cadence tried to use the snapshot feature in a video call, the application GUI crashed. However, he was not kicked out of the meeting automatically, and I could still see and here him. Strangely, when he restarted the GUI, it did not show that he was in a meeting (I could still see him the the meeting). Then he called me while we were already in a meeting together (from my perspective). When I accepted his call, I was kicked out of my current meeting and added to the new one.
|
||||||
|
|
||||||
|
It is stongly reccomended that this issue is fixed ASAP. The GUI needs to be properly linked to the calls.
|
||||||
|
|
||||||
|
**Finding 3: Recognition rather than recall** Cadence was unable to find how to add a new contact. He was able to find a way to share a link to his profile. However In my GUI, I was very clear how to add a contact. The buttonw was displayed very prominently at the top of the contacts list. This seems to hint at an underlying issues that the GUI is not consistent across users. It is relevant to note that Cadence was using Linux and I windows.
|
||||||
|
|
||||||
|
There are two recommendation here. Firstly, the linux app should be changed so that it is easy. Secondly, consistency across operating systems should be made taken into account.

|
||||||
|
| visibility of system status | 3 | Call | The the close window button does not leave the meeting. It pops up the small view. If the user closes this window. The user still does not leave the meeting and there is not GUI | make closing the windows prompt the user if they want to leave the meeting |
|
||||||
|
| error prevention | 3 | Call | The application crahed when cadence tried to take a snapshot. Then I could still see him even though he didn't know he was still in the meeting | The snapshot feature should not cause a crash. And when the GUI closes, the user should leave the meeting |
|
||||||
|
| Recognition rather than recall | 3 | N/A | I do not know how to add somebody else as a contact. I found a way to share a link to my profile, but I don’t know how to use a link that was shared with me. | There should be clear and obvious steps on how to add a contact. If the person has no contacts then the buttons should be displayed more prominently. |
|
||||||
|
| Visibility of system status | 3 | Call | After Skype restarted from the snapshot button crash, the interface seemed like I wasn’t in a call: there was no call overlay, I couldn’t see or hear the other person, and the buttons prompted to start a call rather than stop it. However, my partner could actually see and hear me the whole time, without me knowing! | The application should always tell you when you are in a call. |
|
||||||
|
| User control and freedom | 3 | Private conversation | Logging out and logging in again permanently deletes the entire private conversation on your side without warning. | It should remember the conversation, or if this isn’t possible, it should warn you about the consequences before you log out. |
|
||||||
|
| Visibility of system status | 3 | Call | If a skype window is closed while in a audio or video call, you remain in the call, despite the app being closed. | Either have a warning that the app is closing but you will remain in the call, or have a warning that closing the app will terminate your connection to the call |
|
||||||
|
| Visibility of system status | 2 | Audio/video settings | It is not clear whether or not the microphone test is running | There should be a visible indicator showing that the microphon test is running |
|
||||||
|
| Visibility of system status | 2 | Screenshare | The only indicator that you are sharing your screen is the button changing from “start sharing” to “stop sharing”. It is easy to forget you are sharing, which could potentially cause huge embarrassment! | There should be a permanent indicator that is visible even while using other applications. |
|
||||||
|
| Help users recognise and recover from errors | 2 | Account creation | You cannot use a PNG image as a profile picture, only a JPEG image. | Allow PNG images too, or automatically convert them when the user tries to pick them. |
|
||||||
|
| Flexibility and efficiency of use | 2 | Audio/video settings | When adjusting your audio and videos settings the setting for your webcam is hidden | It should be moved up so the use doesn't have to scroll |
|
||||||
|
| recognition rather than recall | 2 | Call | After opening the sidebar during a call there is no indication of how to hide it | There should be a button to close the sidebar during a call |
|
||||||
|
| User control and freedom | 2 | Mini Viewer | When ‘minimising’ Skype into a mini-player while on video call, the icon for screen-share is visible, and easily confused with the ‘maximise’ button to return the screen to the normal viewer | Have the button for screen share clearer of its purpose, and have a resize option when in mini-player |
|
||||||
|
| Match between system and the real world | 2 | Contacts list | Contacts who have sent you a message are not displayed in the “chats” section until you send a message back. | Text chats should always be displayed in the text chats section. |
|
||||||
|
| consistency and standards | 2 | Call | When one participant enters together mode, it force all the participant into together mode. But the users must all individually leave together mode. | It should be made clear that this is how is works as this was unexpeted behaviour |
|
||||||
|
| Flexibility and efficiency of use | 2 | Call | To click the horizontal dot menu in the bottom left the user must mouse over the react button which opens a popup. This menu usually closes after the mouse is moved off but sometimes it stays | The react menu should be moved or the mouse over function should be fixed |
|
||||||
|
| User control and freedom | 2 | Call | My partner has the ability to use a custom background image, but I don’t have this feature on my end. | Everybody should have the feature! I don’t know why I don’t have it. |
|
||||||
|
| Match between system and the real world | 2 | Private conversation | There is a feature to start a private conversation. Does this imply that conversations are usually not private? | The application should describe what a private conversation means, and explain whatever the downsides are that mean that it can’t be the default option. |
|
||||||
|
| Aesthetic and minimalist design | 2 | Call | When switching applications, Skype opens a floating window to contain the call, which will overlap other applications. | This feature is helpful but there needs to be a way to permanently dismiss it so people can work while in a call. |
|
||||||
|
| Consistency and standards | 2 | N/A | Quitting and restarting the application caused me to be logged out. | It’s a program that is installed on my computer, so it makes sense to keep me logged in. |
|
||||||
|
| recognition rather than recall | 2 | Call | not clear how to exit together mode | Have some indicator of |
|
||||||
|
| User control and freedom | 2 | Text chat | You cannot send a message that starts with a slash. | You should be able to send messages starting with a slash. |
|
||||||
|
| Recognition rather than recall | 2 | General | The toolbar that typically runs along the top of the screen is only available/viewable on the app after pressing alt, and making any action outside of the toolbar removes it again | Have an option to toggle toolbar on/off, and/or make it clearer that alt engages the toolbar |
|
||||||
|
| Help and documentation | 2 | General | To get help with Skype, the toolbar has to be toggled or settings must be opened and navigated through to find the help section | Have a more easily accessible help button, perhaps near the notifications/create group .etc |
|
||||||
|
| Visibility of system status | 2 | Chat | When removing a message, it is not made clear whether it will remove the message for everyone, or just yourself | Clarify that removing the message removes it for all participants |
|
||||||
|
| Flexibility and efficiency of use | 2 | Chat | To view bookmarked messages the user must navigate through their own profile to the bookmarks tab, where all bookmarks from all chats are kept, unsorted | Have an option to view bookmarked chats from certain groups, or have sorting criteria (date, group etc) |
|
||||||
|
| Aesthetic and minimalist design | 1 | Profile | When trying to click on your profile, if the status symbol is clicked a dropdown menu appears that gives you the ability to set your status (active, away, DnD etc), but this option is already included in the main dropdown from clicking onto your profile | Remove the separate function to help mis-click prevention |
|
||||||
|
| Match between system and the real world | 1 | DnD popup | When entering Do Not Disturb, a pop-up notifies you that you will not receive notifications while this is on. The popup has three options to exit it, ‘OK’, ‘View Settings’, and ‘Don’t ask me again’ | Improve the wording. Instead of Don’t ask me again, have ‘don’t show me this again’ or something of the like |
|
||||||
|
| User coontrol and freedom | 1 | Mini floating window | There is no dedicated button to maximise the floating window | A dedicated button should be added to maximise the floating window |
|
||||||
|
| Match between system and the real world | 1 | New Group | When a new group is created, there are two options presented for adding people to the group. There is ‘invite’ and ‘add people’ as two separate options. One option is for adding people through a link, and one is for inviting contacts. However, the add people option also contains an option for adding via link. | Remove the invite option, as both are covered under add people. |
|
||||||
|
| Consistency and standards | 1 | General | Throughout the app, there are multiple different designs for the add members button. There are three different actions that can be taken to add members to a group, and they all have different icons | Generalise the icons so that they all follow the same design, that way they are recognisable throughout the application |
|
||||||
|
| user control and freedom | 1 | Audio and video settings| cadence cannot add a custom background | It should at least say why he cant |
|
||||||
|
| Flexibility and efficiency of use | 1 | Call | When a user is using multiple displays, even if the large skype window is visible the floating windows opens | The floating window should no open in this situation |
|
||||||
|
| Help and docmentation | 1 | Call | When in a call by yourself the record button is grayed out and not pressable. There is no indication as to why | On mousing ove the button it should say why it is grayed out |
|
||||||
|
| Aesthetic and minimalist design | 1 | Account creation | On one of the screens, the “continue” button must be clicked twice in order to continue. | The continue button should continue. |
|
||||||
|
| help and documentation | 1 | Chat | no information about what private mode is | more information should be iven to the user |
|
||||||
|
| Aesthetic and minimalist design | 1 | Top of the screen | Informational banners appear here and do not go away until they are interacted with. They do not display helpful information. Sometimes duplicates should appear. | The banners should go away when they are no longer relevant. |
|
||||||
|
| Match between system and the real world | 1 | Call | “Together mode” is poorly named and does not accurately indicate what it will do. | This feature could have a name like “background scene”, or tooltip text, or some other help mechanism. |
|
||||||
|
| Match between system and the real world | 1 | Polls | Somebody clicking or unclicking a poll option sends me a notification sound. These poll events contain little information on their own, so there’s no reason for them to notify immediately. | Do not notify for people clicking polls. |
|
||||||
|
| Match between system and the real world | 1 | Contacts list | There is a feature to “send a contact”, though this offers to send a person their own contact card. | Do not offer to send people their own contact cards. |
|
||||||
|
| Consistency and standards | 1 | Call | The “view” button has an inconsistent appearance. It activates a dropdown but looks like a functional button. | Add an arrow indicator to the button so that it matches the rest of the application’s conventions. |
|
||||||
|
| Consistency and standards | 1 | Polls | It’s not obvious that a poll option highlighted in blue indicates that you should clicked that option. | Poll options should be represented as traditional checkboxes, rather than weird coloured rectangles. This also makes it clear that you can click again to undo your vote, which is already a feature. |
|
||||||
|
| Consistency and standards | 1 | Main menu | There is an option to “download the app”. I am already using the desktop application. | The text should state “phone app” to contrast it from desktop app. |

# Induction
|
||||||
|
## PECS
|
||||||
|
Phases of argument by induction
|
||||||
|
|
||||||
|
- Preparation -> most important
|
||||||
|
- Execution -> becomes routine if prep is good
|
||||||
|
- Checking -> second most important
|
||||||
|
- Satisfaction
|
||||||
|
|
||||||
|
### Preparation
|
||||||
|
- isolate the property that you are trying to verify and the parameter, n, associated with is
|
||||||
|
- e.g., min possible size of set of rank k is $2^n$
|
||||||
|
- Confirm by hand that for small values of the parameter, the property is true
|
||||||
|
- Use previous cases as assumptions
|
||||||
|
- Pause and reflect
|
||||||
|
- If you understand what's going on -> proceed to execution
|
||||||
|
|
||||||
|
### Execution
|
||||||
|
Technical and prescribed (once you're an expert you can take some liberties)
|
||||||
|
|
||||||
|
Four parts
|
||||||
|
- statement
|
||||||
|
- verificatio of base case
|
||||||
|
- inductive step
|
||||||
|
- conclusion
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- we will prove that, for every non-negative integer $n$, *insert property here*
|
||||||
|
- For $n = 0$, *The property* is true because *explicit verification of this case*
|
||||||
|
- for any $n > 0$, assuming *the property* is true for $n-1$ (or, for all $k < n$), *the property* is true at $n$ because *explain why we can take a step up*
|
||||||
|
- Therefore, by induction, *the property* is true for all n.
|
||||||
|
|
||||||
|
### Checking
|
||||||
|
Basically debugging without a compiler to find errors
|
||||||
|
- have you forgotten anything? e.g., the base case
|
||||||
|
- Does the inductive step work fro 0 to 1? or are they irregular
|
||||||
|
- Make sure that you are only assuming the result for things less than $n$
|
||||||
|
- ideally show someone and try to convince them (dont let them be polite)
|
||||||
|
- if necessary go back to execution or preparation
|
||||||
|
|
||||||
|
### Satisfaction
|
||||||
|
Commence satisfaction.
|
||||||
|
Confidence +100. 😆
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
### Union Find - min size for set of rank k
|
||||||
|
|
||||||
|
- Initially every element is its own representative and every element has rank 0;
|
||||||
|
- when we do a union operation, the the two reps have different ranks, the ranks stay the same
|
||||||
|
- when we do a union operation, if the two reps have the same rank, then the rank increases
|
||||||
|
|
||||||
|
minimum (and only) size of a rank 0 rep is 1
|
||||||
|
|
||||||
|
to get a rank 1 representative, we form a union of either a rank 0 and a rank 1 set or two rank 0 sets
|
||||||
|
for the minimum possible size, it must be the second case, and the two rank 0 sets must be each of minimum size 1, so this gives minimum size for a rank 1 set of 2
|
||||||
|
|
||||||
|
To get a rank 2 rep, we form a union of either rank 2 and rank 0 or 1 set, or two rank 1 sets
|
||||||
|
For the minimum possible size, it must be the second cae, and the two rank 1 sets must each be of minimum size 2, so this gives minimum size for a rank 2 set of 4
|
||||||
|
|
||||||
|
To get a rank $n$ rep, we form a union of either rank $n$ and rank $k$ set for some $k<n$ or two rank $n-1$ sets.
|
||||||
|
For the minimum possible size, it must be the second cae, and the two rank $n-1$ sets must each be of minimum size, which we are **assuming** $2^(n-1)$, so this gives minimum size for a rank $n$ set of
|
||||||
|
|
||||||
|
> $2^{n-1} + 2^{n-1} = 2\times2^{n-1} = 2^n$

#### Review Questions
|
||||||
|
1. How is a source code editor different from an IDE
|
||||||
|

# Integrated Development Environments
|
||||||
|
|
||||||
|
## Source code editors
|
||||||
|
- editor applications to help software development
|
||||||
|
- provide features that help editing code
|
||||||
|
- auto indent, bracket matching, syntax hl, auto completion, rapid navigation
|
||||||
|
- run/test code
|
||||||
|
|
||||||
|
## Integrated dev env
|
||||||
|
- allow you to remain within one application when carrying out software development work
|
||||||
|
- can edit source files
|
||||||
|
- can compile source files
|
||||||
|
- can run debugger
|
||||||
|
- integrates version management
|
||||||
|
- some attach tools to running applications
|
||||||
|
|
||||||
|
### LSP - syntax highlighting
|
||||||
|
- allows IDE's to communicate with a "language enging"
|
||||||
|
- ides dont need
|
||||||
|
|
||||||
|
shift from syntac to semantics
|
||||||
|
e.g.,
|
||||||
|
- vs code chck file on opening
|
||||||
|
- lsp reports type mismatches
|
||||||
|
- rich editor functionality
|
||||||
|
- autocompletion with appropriate context
|
||||||
|
- information displayed on mouse hover
|
||||||
|
- jumping to definitions on mouse hover
|
||||||
|
- safe refactoring -> better than blind search and replace
|
||||||
|
- diagnosticso -> e.g., display results of unit tests within editor
|
||||||
|
|
||||||
|
### Navigation
|
||||||
|
- within files
|
||||||
|
- bracket matching
|
||||||
|
- block folding
|
||||||
|
- multi file
|
||||||
|
- multiple files at the same time
|
||||||
|
- rapidly jump between files
|
||||||
|
- search across all files
|
||||||
|
- collaboration e.g., live sharing
|
||||||
|
|
||||||
|
### Modern IDEs
|
||||||
|
- microsoft
|
||||||
|
- vscode -> free open source, highly popular
|
||||||
|
- visual studio -> integrates mobile and cloud development
|
||||||
|
- java enivronments
|
||||||
|
- eclipse - early leader in java, supports other languages
|
||||||
|
- netbeans -> also includes web dev tooling
|
||||||
|
- jetbrains -> IntelliJ IDEA, pycharm, phpstorm
|
||||||
|
- google's android studio -> official android IDE
|
||||||
|
- apple's Xcode -> free, macOS/iOS focus
|
||||||
|
|
||||||
|
## Early programming
|
||||||
|
- dedicated machines
|
||||||
|
- punched card programmer: separate machine from computer than reads cards
|
||||||
|
- punched cards recore code and or data in binary
|
||||||
|
- grid of positions, each representing a binary digit (bit)
|
||||||
|
- each position in punches out, or not
|
||||||
|
- analgogue electronic devices where you phsyicall wire things up
|
||||||
|
- gaining interest now for use in machine learning
|
||||||
|
|
||||||
|
### Bootstrapping
|
||||||
|
- already built tools can be used to builder better tools for building better tools etc.
|
||||||
|
- e.g., first assembler was made in maching code. But after that they could use the assember to make a better assembler
|
||||||
|
|
||||||
|
### Early dev environments
|
||||||
|
- command line based
|
||||||
|
- text based terminals
|
||||||
|
- command shell is the running application
|
||||||
|
- Can use terminal to drive interactive languages
|
||||||
|
- can edit, store software code
|
||||||
|
- can compile cose and run resulting executables
|
||||||
|
- it is still practical to do software development this way
|
||||||
|
- vim etc

|
||||||
|
|
||||||
|

# Interviews
|
||||||
|
## Use Cases
|
||||||
|
- [Evaluating designs](content/notes/evaluating-designs.md)
|
||||||
|
- [Requirements elicitation](content/notes/requirements-elicitation.md)
|
||||||
|
- [Needfinding](content/notes/needfinding.md)
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
- direct and stuctured
|
||||||
|
- semi structured
|
||||||
|
- usually top down
|
||||||
|
- effective for high level interface evaluation
|
||||||
|
- need careful planning, experts, difficult to analyse
|
||||||
|
- not a controlled experiment technique
|
||||||
|
|
||||||
|
## Conducting an interview
|
||||||
|
### Choosing participants
|
||||||
|
- some is better than none
|
||||||
|
- get pople who are representive of users
|
||||||
|
- users of existing similar system
|
||||||
|
- non-users -> why people arent using a system
|
||||||
|
- e.g., lecture support system
|
||||||
|
- teachers
|
||||||
|
- students
|
||||||
|
- staff
|
||||||
|
- admins
|
||||||
|
- parents
|
||||||
|
- freshman
|
||||||
|
- phd
|
||||||
|
- international domestic
|
||||||
|
- stronger and weaker
|
||||||
|
|
||||||
|
#### Recruiting
|
||||||
|
- Craiglist (in US)
|
||||||
|
- your network
|
||||||
|
- cheaper for less speciales users
|
||||||
|
- if you can convince people you are imporving the world they might volunteer
|
||||||
|
- if they think is is for profict they will expect to be paid
|
||||||
|
- if you cant pay -> you cant use a token of appreciation
|
||||||
|
|
||||||
|
### Process
|
||||||
|
- introduce yourself explaint he purpose
|
||||||
|
- the interview is about them, not you?
|
||||||
|
- begin with open, unbiased questions-> then follow up
|
||||||
|
- ask the questions, and let them answer
|
||||||
|
- have breaks and give them time
|
||||||
|
- have a clear separation between the general introduction, the actual interview, and post inteview discussions
|
||||||
|
|
||||||
|
### Questions to avoid:
|
||||||
|
- leading questions
|
||||||
|
- what would they do / like / want in a hypothetical scenario
|
||||||
|
- how often they do things
|
||||||
|
- how much they like things on an absolute scale
|
||||||
|
- avoid binary questions
|
||||||
|
|
||||||
|
## Pros/cons
|
||||||
|
+ free and open answers
|
||||||
|
+ sense of active contribution
|
||||||
|
+ oppportunity for follow up
|
||||||
|
- time consuming and resource intensive
|
||||||
|
- dependent of commication skills of analyst
|
||||||
|
- location/schedule can make this impractical

# Lecture 10 Heaps and heap sort
|
||||||
|
## 1 Overview
|
||||||
|
[Heap](content/notes/heap.md)
|
||||||
|
|
||||||
|
## 2 Operations
|
||||||
|
### 2.1 Add element
|
||||||
|
Assumptions
|
||||||
|
- access first vacant position
|
||||||
|
- set (or find) the value $H.q$ stored in any (occupied) position $q$
|
||||||
|
- access parent of any given position
|
||||||
|
- identify when we're at the root
|
||||||
|
(all in constant time)
|
||||||
|
|
||||||
|
Outcome: Change $H$ by adding x to it, while maintaining the heap conditions
|
||||||
|
|
||||||
|
```
|
||||||
|
p <- first vacancy, H.p <- x
|
||||||
|
while p is not the root and H.parent(p) < H.p do
|
||||||
|
swap H.parent(p) and H.p
|
||||||
|
p <- parent(p)
|
||||||
|
end while
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2.2 Remove the maximum
|
||||||
|
Outcome: Change H by removing its maximum (i.e., root) value wile maintaining the heap conditions
|
||||||
|
|
||||||
|
```
|
||||||
|
v <- H.root
|
||||||
|
set H.root to be the value stored in the last occupied position
|
||||||
|
p <- root
|
||||||
|
|
||||||
|
while p has children
|
||||||
|
if the largest value, H.c of a child of p is greater than H.p then
|
||||||
|
swap H.c and H.p, p <-c
|
||||||
|
else
|
||||||
|
Break
|
||||||
|
end if
|
||||||
|
end while
|
||||||
|
|
||||||
|
return v
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
### 2.3 Complexity
|
||||||
|
In addition, we move along a branch from an added element up to the root, fixing violations as we go
|
||||||
|
|
||||||
|
In removal, we move from the root down through some branch until all violations are fixed (can only occur if node has children)
|
||||||
|
|
||||||
|
So both loops do most Ο(lg n)
|
||||||
|
|
||||||
|
### 2.4 Storage
|
||||||
|
|
||||||
|
|
||||||
|
- Array
|
||||||
|
- root at position 0 and children at 1 and 2
|
||||||
|
- children of 1 to in 3 and 4, children of 2 go in 5 and 6
|
||||||
|
|
||||||
|
- first vacant pos --> heap[n]
|
||||||
|
- value at pos q --> heap[q]
|
||||||
|
- get parent of q --> parent(q) = (q-1)/2
|
||||||
|
- get children of q --> (2 * q) ± 2
|
||||||
|
- identify if q is root --> q == 0
|
||||||
|
|
||||||
|
### 2.5 Implementation
|
||||||
|
|
||||||
|
Use java.util.PriorityQueue
|
||||||
|
|
||||||
|
## 3 Heap Sort
|
||||||
|
In place and ϴ(n lg n)
|
||||||
|
|
||||||
|
- start with array
|
||||||
|
- using itself as a heap, add the elements one at a time until all been added
|
||||||
|
- Then remove them one at a time - the largest elements gets removed first and the place where is needs to be put gets freed from the map
|
||||||
|
|
||||||
|
## 4 Heap vs Merge
|
||||||
|
heap --> in place, ϴ(n lg n)
|
||||||
|
merge --> not in place, Ο(n lg n)
|
||||||
|
|
||||||
|
Merge is preferred because
|
||||||
|
|
||||||
|
- MS can take advantage of partially sorted data (hence ϴ() vs Ο())
|
||||||
|
- MS memory accesses are good fast
|
||||||
|
- overwrites allow for optimizations that swaps do not
|
||||||
|
|
||||||
|
extra memory cost of merge sort is negligible
|
||||||
|
|
||||||
|
∴ Merge sort is faster

# Lecture 11 Class Diagrams
|
||||||
|
e.g., 
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 1 Stereotypes
|
||||||
|
add further meaning to fields and methods
|
||||||
|
- e.g., << unique >>, << abstrat >>, << interface >>,
|
||||||
|
|
||||||
|
## 2 Packages
|
||||||
|
group classes together
|
||||||
|
break system to logical chunks
|
||||||
|
package diagram, a class diagram with nothing but packages
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 3 Associations
|
||||||
|
UML anaglogue of ERD relationsips
|
||||||
|
- multiplicity
|
||||||
|
- realtionshpa nd role names
|
||||||
|
|
||||||
|
PlUS
|
||||||
|
- naviagability --> instances of one class can pass messages to instances of another
|
||||||
|
- several differnt types, e.g., composition, aggregation, associateive classes
|
||||||
|
|
||||||
|
### 3.1 multuplicity
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
ERDsd effectively only do zero one many
|
||||||
|
UML can to any non negative integer
|
||||||
|
default is 1
|
||||||
|
|
||||||
|
### 3.2 association names
|
||||||
|
|
||||||
|
|
||||||
|
- usuallya verb phrase like "assings", "manages", "enrols in" ...
|
||||||
|
- more useful is conpetual level diagrams
|
||||||
|
- optional arrow head ()
|
||||||
|
|
||||||
|
### 3.3 Role names
|
||||||
|
|
||||||
|
|
||||||
|
At conceptual level, indicates role of class in association.
|
||||||
|
|
||||||
|
At implementation level:
|
||||||
|
- implies a field in class at opposite end
|
||||||
|
- should include visibility
|
||||||
|
- closely related to navigability
|
||||||
|
|
||||||
|
### 3.4 Navigability
|
||||||
|
|
||||||
|
|
||||||
|
specifies whether we can "navigate from one end of an association to another"
|
||||||
|
affects how we code access paths between objects
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- loan instance can see loanitem instances it contains via private field items
|
||||||
|
- a loanitem instance can't see loan instance that contains it
|
||||||
|
- must alwasy include relevant role names
|
||||||
|
- no arrows = two arrows = bidirectional
|
||||||
|
|
||||||
|
#### 3.4.1 why not always bidirectional
|
||||||
|
|
||||||
|
- more complex code --> many references/collections to manage
|
||||||
|
- navigation paths are not all equally important
|
||||||
|
- e.g., "what items are in this loan" vs "what loans does this item appear in"
|
||||||
|
- determined by requrements and typical usage
|
||||||
|
- some classes are more "central"
|
||||||
|
- usually at the "one" end of accociations
|
||||||
|
- often represent transactional entities e.g., loan, sale, order
|
||||||
|
- navigability readiates outwards from them
|
||||||
|
|
||||||
|
there are exceptions as always e.g., patron <-> item
|
||||||
|
|
||||||
|
|
||||||
|
### 3.5 Aggregation
|
||||||
|
|
||||||
|
|
||||||
|
one class is made up of one or more other classes
|
||||||
|
container and content instances _can_ exist separately
|
||||||
|
usually implied by multiplicity and navigability
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- computer is made u of several components
|
||||||
|
- library catalogue is made up of many items
|
||||||
|
|
||||||
|
|
||||||
|
### 3.6 Composition
|
||||||
|
|
||||||
|
|
||||||
|
stonger form of aggregation
|
||||||
|
container and content _cannot_ exist separately
|
||||||
|
usually implied by multiplicity and navigability
|
||||||
|
|
||||||
|
e.g.,
|
||||||
|
- building contains many rooms
|
||||||
|
- loan includes several items
|
||||||
|
|
||||||
|
- coicident lifetime
|
||||||
|
- multiplicity at least 1 at both ends
|
||||||
|
- deleting an containter must also delete all associated contents
|
||||||
|
- creating a container should also create some contents
|
||||||
|
|
||||||
|
|
||||||
|
### 3.7 Associative classes
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
- used for conceptual design
|
||||||
|
- similar to associative entities
|
||||||
|
- many to many relationship with additional independent fields
|
||||||
|
- resolved into class at implementation level
|
||||||
|
|
||||||
|
### 3.8 Specialisation generalisation
|
||||||
|
|
||||||
|
|
||||||
|
class inheritance
|
||||||
|
- e.g., book and disc are subclasses of (specialise) Item
|
||||||
|
- inherit all public fields and methods of superclass
|
||||||
|
- can add their own fields and methods
|
||||||
|
- Compare with specialisation of actors and use cases
|
||||||
|
|
||||||
|
## 4 Domain class model\
|
||||||
|
|
||||||
|
|
||||||
|
only modles the associations among concepts from problem domain
|
||||||
|
|
||||||
|
can be at conceptual level or implementation level
|
||||||
|
|
||||||
|
## 5 System class model
|
||||||
|
|
||||||
|
Models associations among domain objects and system components; implementation level only

# Lecture 11 Continuous Integration 2
|
||||||
|
|
||||||
|
Ci runs pipellines defined in .gitlab-ci.yaml asynchronously
|
||||||
|
|
||||||
|
ci usually tets abd buiolds your prokects
|
||||||
|
|
||||||
|
runs on a repo server
|
||||||
|
- usuially persistent, internet accessible
|
||||||
|
|
||||||
|
## 1 Gitlab overall architecture
|
||||||
|
 : not in exam
|
||||||
|
- many different services used
|
||||||
|
|
||||||
|
## 2 Gitlab runners
|
||||||
|
run CI scripts
|
||||||
|
- gitlab.com is a cloud computing service
|
||||||
|
- allows elf hosting which is what CS does
|
||||||
|
- altitude is a gitlab instance at CS
|
||||||
|
- servers to host runners that run CI scripts
|
||||||
|
- servers that host websites, e.g., cspages.otago.nz
|
||||||
|
- Gitlab can invoke runners that you host
|
||||||
|
- e.g., to use a particular GPU, or other hardware you have
|
||||||
|
- GItlab runner itself is a small program written in Go
|
||||||
|
|
||||||
|
### 2.1 Runner architecture
|
||||||
|
|
||||||
|
- runs jobs
|
||||||
|
- on isolated infrastructure
|
||||||
|
- ... to maintain secrity
|
||||||
|
- that is set up on demand
|
||||||
|
- ... handle load variation
|
||||||
|
- suits cloud computing
|
||||||
|
|
||||||
|
RHS shows GitLab.com's CI hosting
|
||||||
|
uses google cloud
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
 : not in exam
|
||||||
|
|
||||||
|
## 3 How CI chagned website hosting
|
||||||
|
|
||||||
|
- need to share stifacts produced by CI jobs
|
||||||
|
- using the web to share artefacts is ideal
|
||||||
|
- so now most repo servers also host websites
|
||||||
|
- these are static websites: all content is fixed
|
||||||
|
- CI can run static website generators (SSGs)
|
||||||
|
- git repo contains source code of website
|
||||||
|
- CI pipelines transforms souce code into HTML fiels
|
||||||
|
- HTML files then hosted as a website by repo sever
|
||||||
|
|
||||||
|
e.g., https://cosc202.cspages.otago.ac.nz
|
||||||
|
|
||||||
|
|
||||||
|
## 4 Debugging CI scripts
|
||||||
|
|
||||||
|
- first ensure config files YAML is valid
|
||||||
|
- vuilt in gitlab editor checks YAML as you type
|
||||||
|
- commands runfrom shell that fail return an exit code
|
||||||
|
- most unix shells sotre exit code of previous commands in $
|
||||||
|
- So if variable $? (return code of prevous command) is non-zero, the previous command failed
|
||||||
|
- Git lab considers CI job as failed if any command fails
|
||||||
|
- your shell scripting can choose to hide this exit code
|
||||||
|
- e.g., `if command supposed to fail; then true; else true; fi`
|
||||||
|
- Complex scripting? Beste to put script in a file and run it from CI
|
||||||
|
|
||||||
|

## 1 Show system status
|
||||||
|
- show system stats
|
||||||
|
|
||||||
|
- feedback depends on response time
|
||||||
|
- <1s just show outcome
|
||||||
|
- ~1s feedback that activity is underway
|
||||||
|
- >>1s show fractional progress time
|
||||||
|
|
||||||
|
- 0.1 seconds --> feels instantaneusly
|
||||||
|
- 1 second --> about the limit for flow to be uinteruippted
|
||||||
|
- 10 seeconds --> the limit for keeping users attention
|
||||||
|
|
||||||
|
when:
|
||||||
|
- when action is requried
|
||||||
|
- show storage space
|
||||||
|
- making changes
|
||||||
|
- next steps --> user input required
|
||||||
|
- completion --> some task has finished
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 2 familiar metaphors and language

## 1 Consistency and standards
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
good and bad
|
||||||
|
- standards (user interface guidelines) are always chaning
|
||||||
|
|
||||||
|
differ between platforms
|
||||||
|
evolve over time
|
||||||
|
|
||||||
|
