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.

Lichess potentially allowed promotion of pawns to king
Well, only since this year, it seems.

The reason why you need good, thorough tests when writing chess engines
From another reddit thread I got the link to the commit with the fix. Thankfully, they did add a test case for this: https://github.com/lichess-org/scalachess/commit/f5218340b2a229fa519ecd239fe50aee722bcd0f

lichess doesn't let me capture en passant in the game, only in the analysis board
To be fair, that TODO has only been there for three weeks, which seems reasonable, especially considering it was written by a volunteer.
- Why does nobody play Capablanca chess anymore, while Fisher random is quite popular?
-
White to move. This position is a win in lichess, draw in chess.com.
Lichess does not check for mate. It simply doesn't consider KBvKN a drawn endgame.
- Where can I find lines to test my new music-memory technique?

Ask HN: Codebases with great, easy to read code?
https://github.com/lichess-org/scalachess/tree/master/src/ma...
It's funny because I remember comparing it to mine that I had tried to write during college, and appreciating how much better it is.
Pay attention to how there's a bunch of different types of chess in there too, and how that's factored.

A writeup on definitions of "insufficient material"
The Lichess implementation is as follows:
-
How chess websites define insufficient mating material.
The Lichess implementation does not fully comply with those rules. It looks strictly at the material on the board.

Always wondered if lichess is smart enough to notice this is a draw
For reference, here's the current implementation.

Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months
GPL2
Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?
IANAL, apologies if I miss understand license requirements.

Writing x86 SIMD using x86inc.asm (2017)
This turns out to be a lot of assembly macros to help write one x86 assembly. https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/x86/x...
The sibling comment recommending compiler intrinsics is probably the best way to go for writing SIMD code. A mixture of `` style types and intrinsics to specify instructions is a solid 90% solution compared to assembly.
If you want that last 10%, I think macros are putting the emphasis in the wrong place. They're a somewhat easy way to build up a language abstraction which will work if held carefully, but I'm confident the dev experience using this abstraction when you write invalid code will be deeply confusing.
I would suggest to write a parser instead of the macros. That'll tell you clearly when the syntax is invalid (though possibly not with much precision) and it'll give you a place to put semantic analysis for where valid syntax encodes nonsense. Do the equivalent of the macro expansions on the parsed tree instead of on the text. Emit asm as the "back end".

Video Generation with Python
You might have heard of FFMPEG or ImageMagick for image and video edition in a programmatic way. MoviePy is a Python module for video editing (Python wrapper for FFMPEG and ImageMagick). It provides functions for cutting, concatenations, title insertions, video compositing, video processing, and the creation of custom effects. It can read and write common video and audio formats and be run on any platform with Python 2.7 or 3+.

11 Ways to Optimize Your Website
There are many cloud-based tools and websites that can convert your images, but the problem with these tools is that you usually have to upload the files for them to be processed, and some of their services are not free. In this article, I'd like to introduce a piece of software called FFmpeg, which allows you convert the images locally with one simple command.
