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.

[2016 Day 14 (Part 2)][Python] Is there a trick to speed this up?
Here's an example implementation in Rust, using rayon's parallel iterators to automatically distribute the computation of a range of hashes over all available cores. It solves both parts together in around 3 seconds on my M2 MacBook Pro. Single-threaded, it takes around 25s in Rust and 35s in Python.

Running time goals (more of a survey question)
I love doing optimizations like this but I don't really have enough time anymore to really do it. In 2020 I spent a fair amount of time writing super optimized solutions for the first 10 or so days (repo solving all those days together in 150us i.e. <1ms) but even back then, I eventually stopped since I had other things to do and it took more and more time as the days went on.

Wow, my final solution looks almost exactly the same. Though I calculated my initial answers by hand.

[2021 Day 18] When you check the leaderboard first and see most people taking 30+ minutes
That's certainly not necessary though and really not what makes most of the speed, especially for problems like today's. I don't really look at other leaderboard competitor's solutions much but at least my solutions (ranked ~20 today) are almost always completely vanilla Python (the only exception is networkx for the occasional graph problem but even that isn't really that much of a speedup if you know the common graph algorithms) and always self-contained.

Interesting approach. I guess mine could be considered a bit nicer, doing it recursively and returning the number to add to the left or right.

[2021 Day 15 (Part B)] [Golang] Pretty Organic, If You Ask Me.
My priority Q/heap Dijkstra in Python runs just fine. I don't remember and can't check rn if it was instant or took a second but it definitely wasn't longer than that.

What's everyone working on this week (42/2021)?
Another brilliant source which I've found is https://github.com/timvisee/advent-of-code-2020. Great inspirational use of iterators there.

Hey Rustaceans! Got an easy question? Ask here (12/2021)!
Cool to see the itertools approach here though :) Link to the solution I saw before

Cool! My first time on TWIR with Solving Advent of Code 2020 in under a second. Though it isn't specifically about Rust, I did use Rust.

The use of a different data structure for the low and high side of the look up table made it faster as described here.

No surprise, Rust is fast.
Oh yes, did Advent of Code in under a second last december, shameless plug 😎.
