It's international horseshoe crab day and everyone's invited! Except crabs, because these are not even crustaceans (they are more like spiders and scorpions) ๐Ÿฆ‘๐Ÿงช

Watching pelicans fish and writing SIMD code, A+ vacation so far

Some updates, now at 8.3x performance boost since I started using the new tips and tricks from the Apple performance talk.

Started to use third party benchmarks to compare notes.

On VteBench, comparing MacOS Terminal, main, perf branch and Ghostty yields some amazing results, I couldn't believe my own eyes:

When I first tried, "termbench small", it was a worthless experiment, it would never end. Now, it does better than both MacOS Tahoe and Ghostty:

[RFC] Proposal to establish a Safety Group in LLVM

Abstract This RFC proposes the creation of a Safety Group within the LLVM project, similar to the existing Security Group. The group would serve as a community-driven forum to address the challenges of using LLVM in safety-critical systems development, such as those governed by ISO 26262 (automotive), DO-178C (aerospace), or EN 50128 (railways). It would focus on enabling qualified use of LLVM components through shared infrastructure, quality best practices, documentation, collaboration, and lon...

Can you guess why this door in #Merano (Italy) is so tall? Check the Alt-Text for the solution.
Hint:

The door is located on the square surrounding the main church of the city.

First fireflies of the year!
Construction update: wallers just bending drywall around curves like itโ€™s no thing.

Where to next for static race detection? It is really good at verifying lock based patterns now, but that's not enough for verifying real-world programs, which use all sorts of interesting idioms to avoid races (and hence undefined behaviour!)

On Friday afternoon Karoliine Holter is presenting our TOPLAS paper at #PLDI: "Sound Static Data Race Verification for C: Is the Race Lost?" Joint work with my colleagues from Tartu: Karoliine, Simmo Saan, and Vesal Vojdani.

We identified 20 coding idioms to avoid races by separating accesses in time and space; some existing tool can verify 8 of the 20. If you want to verify real world programs you'd better be able to handle these idioms: we show that they do occur in real programs from the Concrat suite.

Wow! ๐Ÿ˜€
@macst is it so they can bring stained glass windows in and out? Lovely pic...
@macst they wear very large hats
@macst and there was me thinking it was for the bishop's pet giraffe.
@macst I would guess for some sort of reason relating to processionals, like they carry some very tall idol or cross in and out of the church and parade it around.
@macst I guessed it used to be a window but the rising street level turned it into a door. This happened a lot with repurposed Roman buildings.

@macst That's no what alt text is meant for.

The foto shows a yellowish wall with a narrow, wooden door in the middle. Guessing from the height of the door knob, the door must be about 5 metres tall. On the left and right of the door, there are 7 stone tablets attatched to the wall.
#Alt4you

@schokoholic oh thank goodness a rageoholic is here to micromanage this post. we almost experienced a moment of enjoyment there.
@macst ohh I thought the leader of the church used to wear REALLY tall hats
@macst having just heard me say, "Giraffes," out loud, my fellow commuters are slowly moving away while projecting the standard city-dweller nonchalance.
@macst that's really cool!!
@macst
for very tall Catholics
@macst Here is a very tall door in London, off Denmark Street. The building is a theatrical set design store.
@macst Very tall Pope hat.
@macst Probably for carrying of religious relics or icons
The door is so tall and skinny, my first thought is, can you even open the door by simply pushing the knob? The physics of it?! ๐Ÿค”
@macst yes, this is the nephilim entry.
