Metal accelerated renderer for SwiftTerm is out!
It took five different attempts, in the end, I based SwiftTerm's implementation on Ghostty's GPU support - lots of really nice small touches in there.

There is something off going on with the 'g' - like the CoreText codepath is drunk.

Update: CoreText progress, left is with CoreText, right without.
That said, the new approach consumes twice as much memory at startup, so it defeats the purpose of this exercise.

Since Apple won’t include stickers anymore with their iPhones, old stickers are like bitcoin, a finite resource that we can use as a store of value and currency.
Someone set up a proper trading market place for StickerCoin.

yeah I am not a fan either, but the joy of this is that folks that have those codebases might be able to sanitize them- which we should do.

One thing that fascinates me about this private computing is that every big cloud vendor has similar sounding efforts but they never quite come together into a useful package - like baking cookies without the flour.
Lots of hopes and dream, but lacking guidance and a concrete go-to-market roll out plan.
To this day, most advanced secure computing hardware sits unused because we don’t surface the primitives in any actionable form. https://infosec.exchange/@mattburgess/113124728485246481

I need to start a TikTok channel about being a trad programmer.
One that writes code without sprints, stories, epics, reviews, specs.
Just sit down with my keyboard and compiler and watch the build output scroll by.

I am not familiar with him. But many of my friends are immigrants and ChatGPT has changed their lives for that reason alone.

I know people like to shit on these LLM models, but these tools to improve writing are a boon for immigrants.
It is the ultimate accessibility tool.

I’ll buy whatever pro phone they announced today, but really wished pro users were not penalized with the uninspiring colors.
