Solving Complex Problems Through Programming
Friday 3 June 2022 - Block 7
← previous note | most current note | next note →Daily Note
- Hello :-)
- We are going to learn about DNS today, and the next 2 or 3 classes
- We will start by watching this brief video
- This topic is excellent introduction to computer science and networking
- Please log into our classroom library
- Please use the search function for zine, and open the zine: how DNS works
- We will read pages 1 through 7
- We will pause for questions / wonderings
- Please read page 18 and 19
- We will open terminal
- we will use the dig command to look at dns
- type: dig example.com
- try dig other domain
- You will see a view of your browser!
- open this urlin chrome: chrome://net-export/
- start logging, save the file on your desktop, please
- visit two or three websites
- click stop logging
- visit this url: https://netlog-viewer.appspot.com/#import
- import your log and click DNS tab
- We have a wiki article on DNS
A little less comfortable
Content
Programs must solve the problem they were create to solve. We can worry about how effieciently or elegantly they solve the problem later on; not right now. The content of a program entails input, processing and output. All three of these elements must be clearly observable. A key question you will be asked (and you should ask yourself) is: to what extent does your code implement the features required by the specification?
Process
Within the process, we are looking at six guiding questions:
- To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
- To what extent is your code eliminating repetition?
- To what extent is your code using functions appropriately?
- To what extent is your code readable?
- To what extent is your code commented?
- To what extent are your variables well named?
Product
As opposed to content, this section we focus on how well you solved the problem. A key question here is to what extent is your code free of bugs?
A little more comfortable
Content
Programs must solve the problem they were create to solve. You should ask yourself "Am I solving this elegantly?". The content of a program entails input, processing and output. All three of these elements must be clearly observable, and we must see evidence of sanitizing input and raising exceptions. A key question you will be asked (and you should ask yourself) is: to what extent does your code implement the features required by the specification?
Process
Within the process, we are looking at six guiding questions:
- To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
- To what extent is your code eliminating repetition?
- To what extent is your code using functions appropriately?
- To what extent is your code readable?
- To what extent is your code commented?
- To what extent are your variables well named?
For those more comfortable programming, we expect succinct, secure and effecient problem solving.

As opposed to content, this section we focus on how well you solved the problem. A key question here is to what extent is your code free of bugs? The real difference here is the complexity of the problem you have chosen to solve and how well you solved it.
Our Big idea
The big idea for today is Programming.
The essential questions for this topic are:
How do we plan, write, execute, and test instructions a computer can understand and process?
It takes time to explore and really understand a big idea. If you want to
learn more about
programming (which is connected to today's daily note),

.
We are learning this because as a designers must understand scientific and technical innovation. Designers use systems, models, methods, and processes to solve problems.
Reminders & routines:
IF (today == testing_day_for_me) {
remember to go get tested!;
}
IF (this_block == first_block_day) {
read_daily_bulletin;
}
IF (today == Friday) {
current_event_activity();
}
As I am taking attendance:
- Please check now: is visual studio code working from my programming folder?
