#GitHub #GitHubPages #fail This is driving me mad...

Images randomly deciding not to load on all my pages.

Is it just me? Is it my browser's fault? Is it just in Brazil?

I was working on this #shapely + #trimesh page... and I can only see the last image (the animated gif)!

https://abav.lugaralgum.com/material-aulas/Processing-Python-py5/shapely-e-trimesh.html

Update: On this exact page I have bungled the image URLs (I blame Marktext for being stupid and not using a relative reference). But I swear loading problems have been going on other well formed pages.

For me, the most waited and exciting presentation at #PyConUS24 was Jim's (@hx2A) talk: #CreativeCoding with #py5 (@py5coding), the #Python version of #Processing

If you missed it, you can watch it now! https://www.youtube.com/watch?v=pNVn3FPi5PU

I'm so glad I was able to be there! We had a nice "creative coding open space" the next day. I wish @ericof and @TomLarrow could have been there too. #numpy #shapely #trimesh #matplotlib #opencv

Myślicie, że jest wam dzisiaj gorąco?

Najpierw walczyłem z nowym segfaultem w #pydantic 2 z Pythonem 3.12. Nie udało mi się zajść daleko, co najwyżej ustalić, że to #heisenbug.

https://github.com/pydantic/pydantic/issues/7181

Potem testowałem świeży snapshot #LLVM — tylko po to, by odkryć, że testy znów padly na 32-bitowych platformach. Po bisect'cie, okazało się, że przyczyną była zmiana "NFCi" (niezamierzająca zmian funkcjonalnych) do logiki hashowania — wygląda na to, że LLVM drukuje teraz funkcje w kolejności zależnej od platformy.

https://reviews.llvm.org/D158217#4600956

Na koniec walczyłem z segfaultem w testach #trimesh. Najwyraźniej jest to regresja związana z betą #numpy 1.26.0, więc wypracowałem backtrace i zgłosiłem błąd.

#Gentoo #Python

You think it's hot today?

First I've been trying to figure out a new segfault in #pydantic 2 with #Python 3.12. I haven't been able to get far, except for establishing that it's a #heisenbug.

https://github.com/pydantic/pydantic/issues/7181

Then I've been testing a fresh #LLVM snapshot — only to discover the test suite is broken on 32-bit platforms again. After a bisect, it turned out that it was caused by a NFCi change to the hash logic — I guess that the function ordering depends on the platform now.

https://reviews.llvm.org/D158217#4600956

Finally, I've been figuring out a #trimesh segfault in tests. Apparently it's specific to #numpy 1.26.0 beta, so I've gotten a backtrace and filed a bug there.
