Week 15: What

A slow start after a long weekend

1. JS Quiz

• TUE - Did a W3Schools React Quiz. Also viewed a common React questions YouTube video. These raised a few interesting points such:
  • What happens when useEffect dependencies is empty?
  • Why is React designed with immutable state in mind?
  • Why is Pure Component an important design pattern in React?
• WED - Reviewed past weeks' content, SEO and speed. Studied Server Components too, seems it is like Astro Islands. But it seems a lot of effort for minor value... worked out a 4-week plan to investigate and implement projects that might have some value.
• FRI - Reviewed the past 30 CI pipelines. In-depth analysis to follow

2. Behaviour

• TUE - revised 3 questions. Finding blind spots...
• WED - another 3
• THU - did 3
• FRI - speaking louder in practice instead of whisper feels good! Did 3.

3. Leetcode

• TUE - Total Characters in String After Transformations I had the Medium, string solution, turns out they only wanted brute force, not optimised generic formula (it was hard to get to!)
• WED - Total Characters in String After Transformations II, at least got the brute force Hard, string method working well!
• THU - Longest Unequal Adjacent Groups Subsequence II. Breezed through the Easy version of this question and did this Medium, backtracking
• FRI - repeated the question yesterday, managed to pass the backtracking solution. Couldn't figure out the dynamic programming solution though. Practiced going from recursion to memoization to dynamic programming! House Robber
• SAT - Sort Colors a Medium sorting question. Learnt about the 3-pointer Dutch National Flag problem

4. JS Coding

• TUE - Setup astro website! Going to finish the tutorial tomorrow to make a working example of SSR & hydration.
• WED - Revised 2 questions

5. System Design

• TUE - Subdomains. en.wikipedia.org and ads.google.com are both examples of sub-domains. Cloud servers can spin up and allocate the resources where required.
• WED - TODO: continue building the astro website
