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.

CPNG, a backwards compatible fork of PNG
Someone made this: https://github.com/manticore-projects/fpng-java
Replacing zlib might give you a few percentage points' worth of difference, whilst fpnge would likely be several times faster.

Ethically Sourced Lena Picture
Her request is politely-phrased and reasonable. I don't think there's a legal or ethical issue, but respecting the wishes of others when it costs nothing is just kindness.
However, the way that some have seized on it, and then interacted with others in their communities is ... neither polite nor reasonable.

The most famous picture used as a standard in computer science is nudes from Playboy!
How do you know it's not a problem for the people who work with computer vision? Let's take this for example - sure, the request itself was presented very unprofessionally, but this is still an example of someone in a computer vision-adjacent field stating in no uncertain terms that they have a problem with the image.

At one company I worked at only one thing mattered: the yearly bonus
Yes. Without a supporting statement, it's ad hominem. But I provided a supporting statement.
This is the issue I'm taking about: https://mobile.twitter.com/richgel999/status/146443578680850...
Which links to here: https://github.com/phoboslab/qoi/issues/35
Where everyone agrees, yes, the image should be removed. They didn't know about its history. Would he please stop being a gigantic asshole about it.
So if that's not blowing things out of proportion, I don't know what is.

QOI – The Quite OK Image Format
I don't know about CUDA, however I've made an AVX2 based encoder a few months ago : https://github.com/phoboslab/qoi/pull/143
I intend to create an AVX2 based decoder but I had absolutely no time to work on side projects in the past three months.
You might also want to take a look at this streaming encoder if you want to encode large files with a tiny memory footprint : https://github.com/MKCG/php-qoi/blob/main/src/FFI/lib/qoi.c

This is huge: GameMaker Studio 2 now uses QOI image format for textures!
Not only does compression improve this situation today, but using QOI means improvements may continue to come over time. QOI is a very new, open source image format, and that's already proving to be an advantage. By itself, QOI compression is pretty weak, but YoYoGames have forked it and worked in BZ2 compression to surpass the old PNG format. As QOI itself improves and as YoYoGames continues to work on it, it's almost guaranteed that we'll see the compression ratio in GameMaker get better over time.
