The outcome of a bunch of shader tuning last night: the upsample filter (4x sin(x/x) from 20M to 80M points in this test) went from 6.55 ms to 1.5 ms.
Original: 8% of peak DRAM read BW, 31% write, 14% L2$ hit rate.
New (just changed memory access patterns to be more coalesce/cache friendly): 9% read, 37% write, 73% L2$ hit
A similar memory ordering optimization cut the PAM edge detector from about 14 to 10 ms but my SM occupancy is still crap (around 12% of warp slots used)…

United Farm Workers co-founder Dolores Huerta went public with her own account of being raped by Cesar Chavez, following a NYT investigation.
Huerta said she kept the secret because, “I believed that exposing the truth would hurt the farmworker movement I have spent my entire life fighting for.”

I have started playing this weekend the game Metro Exodus and it is pretty cool and... crudel. I like it. But I feel like I will need to read or watch something stupid or "happy" to warm up my heart after playing this game, and I've read that the books are even more crudel.

Face Š Panot, Lecornu a osé jouer la République indivisible, alors que la macronie n'a tenu que par la grâce du RN.
Il a osé.
Le RN et ses 120 députés, héritiers directs de la matrice idéologique des militants qui ont buté Clément Méric, les nervis des ratonnades, les nostalgiques de l'OAS !
Tu parles d'une cohérence morale !
Mais face Š la médiocre intervention de Panot, le coup était facile Š faire.
Nase.

A rare daylight #fireball coming with a loud bang was seen and heard Tuesday morning over the U.S. and Ohio in particular: youtube.com/watch?v=dHBjApk3d6w - see skyweek.wordpress.com/2026/03/ for links to many more reports. And ares.jsc.nasa.gov/meteorite-fa says: "Signatures of falling meteorites are seen in data from three weather radars [...] NASA Meteoroid Environment Office finds that this was a 2m diameter object weighing around 6 metric tons - more of a small asteroid than a large meteoroid. [...] There are meteorites on the ground around Windfall, OH towards River Styx, OH."

I'm rewatching Firefly (on Disney ).
The CGI is obviously lacking modern lighting techniques and often feels soft, the compositing has clipped highlights due to the lack of a modern linear and color-managed workflow. But that's to be expected. The show came out more than 20 years ago!
What matters more is the story and its vibe. I remember it as one of the most beloved sci-fi shows back then, in good company with

I would like to get two 10x10x200cm wooden beams and cut them diagonally to get four very long wedges that I can use to raise my mattress base.
Is that doable or insane? And if doable, and if you're in #Berlin or #Germany, is it something I can ask Bauhaus or the like to do for me (in which…
