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.

H265 vs AV1 - Experiments in Python
Very well written. As others have suggested, you should do a followup using modern perceptual quality metrics like VMAF and ssimulacra2.

A better compact image placeholder hash
I was thinking about that too. Can't answer the question, but I did come across this just the other day: https://github.com/cloudinary/ssimulacra2 Supposedly good for comparing image similarity. Might depend on your use-case, I think it's geared towards image quality moreso than similar photos.

Unusually good compression ratio - Sanity Check
That's the kind of feedback I was looking for, thanks. I usually go by eye, but at 14:1, I was expecting a blurry artefact-ridden mess, and it just didn't look all that bad at first blush.... I'll definitely check out ssimulacra2, thanks for the suggestion. I also need to sit down and do some proper pixel-peeping on a better screen... I think my monitor falls into the 'HD-aren't' class of HDR displays, so I'm likely missing detail somewhere. My purpose is archival, I want to preserve quality but not needlessly waste drive space on less efficient codecs. I'm not concerned by the resultant bit rate, so long as it has improved compression efficiency over the original.

What are all the best known must have software, tools & resources for AV1 enthusiasts?
I am using ffmpeg for encoding with svtav1. For checking parameters before encoding I use ab-av1. For checking VMAF after encoding I use nmkoder. Also worth mentioning is SSIMULACRA 2 which is better metrics than VMAF. SSIMULACRA 2
