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.

Binary-to-text encoding optimised for Twitter and UTF-32
Makes me think of embedding an overlay filesystem / OS over twitter lol.

I found a software on Twitter that allows you to store up to 3MB into a PNG file. The source code is included.
This was made by David Buchanan on Twitter. He explains more in his Twitter post and on Github. It seems like a really cool idea to incorporate into a puzzle, so I figured you guys would like it.

Security Researcher Hides ZIP, MP3 Files Inside PNG Files on Twitter
A security researcher has discovered a novel steganography technique for hiding data inside a Portable Network Graphics (.PNG) image file posted on Twitter, a tactic that could be exploited by threat actors to hide malicious activity. Researcher David Buchanan heralded his discovery on Twitter earlier this week, accompanied by a photo declaring: “Save this image and change the extension to .zip!” He made the source code for his method available in a ZIP/PNG file attached to the image as well as on a post on GitHub that explains his methodology.

What digit bases do you like?
qntm did a fun project of using larger bases, constrained to subsets of unicode instead of ASCII like base64. It's specifically for social channels where you're constrained by the number of code points, but not bytes, so you want to maximize data per code point. base2048 is pretty impressive, and base32768 is just absurd.

Twitter's anti-Mastodon filter evasion
On a semi-related note, they mention base64 encoding messages to evade filters. There were actually other base{n} methods [1] created specifically for Twitter to be more space optimized though not as readily available to operating systems. I guess this is less useful if they are really expanding the text limit to 4k soon but figured I would add it in the event they add a parser for base64.

A rust crate that lets you compress ASCII text to a single Unicode "character"
Actually, in the case of twitter they do some weird counting. It is mostly based on codepoints, true, but some codepoints are considered "heavy" and are counted twice, see https://github.com/qntm/base2048

New Twitter TOS
I know of one case of Twitter doing client side validation [1]. Maybe there are more?

Assemblies-of-putative-SARS-CoV2-spike-encoding-mRNA-sequences-for-vaccines-BNT-162b2-and-mRNA-1273 - RNA vaccines have become a key tool in moving forward through the challenges raised both in the current pandemic and in numerous other public health and medical challenges. With the rollout of vaccines for COVID-19, these synthetic mRNAs have become broadly distributed RNA species in numerous human populations. Despite their ubiquity, sequences are not always available for such RNAs. Standard methods facilitate such sequencing. In this note, we provide experimental sequence information for the RNA components of the initial Moderna (https://pubmed.ncbi.nlm.nih.gov/32756549/) and Pfizer/BioNTech (https://pubmed.ncbi.nlm.nih.gov/33301246/) COVID-19 vaccines, allowing a working assembly of the former and a confirmation of previously reported sequence information for the latter RNA. Sharing of sequence information for broadly used therapeutics has the benefit of allowing any researchers or clinicians using sequencing approaches to rapidly identify such sequences as therapeutic-derived
