The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How should I prepare for Cs post?
For CS, you'll have a headstart if you have a bit of experience with Python and problem-solving. Search around for basic material on Python and if you have the time, attempt some problems on https://dmoj.ca/.
-
What sorts of projects have you been working on?
dmoj.ca ! It's meant more so for competitive coding but some of the problem sets they have fall under the Cryptography category.

Host a mini programming contest
If you want to host something yourself and don't mind doing the setup work, you can run your own instance of PC2 (which was formerly used by the ACM-ICPC contest) or DOMjudge or DMOJ.

Becoming World #2 on Leetcode (by Contest Rating)!
The first type of practice is general problem solving. This is where you build up a strong intuition of problem and develop general problem solving techniques (but not memorising a huge list of techniques). Of course, the only way to improve is to do lots of problems / contests. For those who are more interested in competitive programming, I really like dmoj.ca (they host contests there as well, sometimes I author some :) ). The second type is just learning new concepts or techniques. I can't comment on courses such as "Grokking the Coding Interview" because I simply haven't done them. What I have enjoyed, however, is the CSES handbook (https://cses.fi/book/book.pdf). The book is very well written, and there is an additional problemset to test the concepts you just learnt at https://cses.fi/problemset/. Some of the concepts taught in the book are a bit out of scope for interviews, but would be great for anyone interested in competitive programming.

Personally, I’ve heard good stuff about DMOJ https://dmoj.ca/ Hope it helps :)

Advent of Code (in MiniScript), Day 18
Welcome back to my series of Advent of Code solutions in MiniScript! Day 18 was pretty straightforward, though it presents some interesting choices in how to represent the data -- choices I'm not sure I made optimally.

Late bloomers (that started life closer to 30), how are things going for you?
And I've solved all of the Advent of Code problems so far this year, which is utterly unimportant but still brings me joy.

Coding/programming is absolutely fantastic
If you'd enjoy some coding challenges, advent of code (https://adventofcode.com/) is currently going on.

Advent of Code (in MiniScript), Day 17
Welcome back to my series of Advent of Code solutions in MiniScript! In Day 17 we got to (sort of) play Tetris. Five different Tetris-like shapes fall into a pit, moved left or right on each step according to the input. The first task is to see how high this stack will grow after 2022 blocks have been dropped in.
