The kind of love we pour in the line of business I’m in doesn’t belong in release notes. That would completely defeat the anxious bindiffing and slow incremental discovery of which techniques died, which survived and which are on the chopping block.

Amazing work! I’m surprised to see Apple managed to get synchronous tag checking in production. I wouldn’t have bet on that given the performance constraints. Getting the sign off to get so much security-specific silicon is also a huge accomplishment.

“It is much easier to consider genocide in the past tense rather than contend with it in the present. Legal scholars tend to sharpen their pens after the smell of death has dissipated and moral clarity is no longer urgent.”

The Harvard Law Review refused to run this piece about genocide in Gaza. The piece was nearing publication when the journal decided against publishing it. You can read the article here: bit.ly/47ENL1W
