Screen shot of my quote tweet of Google’s response thread on ffmpeg: Context on the recent ffmpeg AI vuln disclosure kerfuffle. Interested to see if this results in Big Sleep & CodeMender being used in tandem, to address ffmpeg’s core complaint: A huge company like Google should provide patches with their AI bug reports to open source projects

Tweet from Zelenskyy thanking America and the Trump administration with a Grok suggestion underneath “Which territories might Ukraine cede?” This was the tweet: Thank you America, thank you for your support, thank you for this visit. Thank you @POTUS, Congress, and the American people. Ukraine needs just and lasting peace, and we are working exactly for that.
https://interactioninstitute.org/equality-equality-cartoon-gallery/ Cartoon showing equality vs equity vs what we have now. Equality assumes people are all the same height and provides a crate of the same height for each to stand on to see over a fence. Those already tall enough were given a boost, while those shorter still can’t see over the fence. Equity provides enough crates depending on people’s heights to let everyone see over the fence at the same height. What we have now provides the most crates to boost the tallest and a smaller boost to the next tallest, while giving nothing to the shortest.
