New blog post: The Diagonal Seam 📐
Mesa's u_blitter copies pixels by drawing a textured quad - two triangles with a diagonal seam between them. For NEAREST filtering, that seam produces a stripe of wrong texels on GC7000, failing dEQP's nearest_consistency tests.
The proprietary Vivante blob doesn't draw a quad at all. It draws one oversized triangle and lets the scissor clip it. No seam, no problem.

Two more dEQP tests down: dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag -- Pass dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_min -- Pass This one was a fun geometry puzzle. The problem Mesa’s u_blitter is the utility that drivers use for framebuffer blits – copying pixel data between surfaces, optionally scaling and filtering. It works by drawing a textured quad: set up the source as a texture, the destination as a render target, and draw a rectangle with the appropriate texture coordinates. Simple.

Here we go with the last day!
All of this nonsense about getting kids off social media is really just a cover for not legislating the social media companies to make the spaces safe for everyone.
They of course, don't want that as it would affect profits.
Explain again how profits are more important to a society than safe spaces?

Another email to my MP, who is also my parents' MP.
They are rural residents who are no longer able to drive (and they don't have a computer). They arranged for a courtesy mailbox through Canada Post, which enables them to send and receive mail once a week.
Except someone at the post office decided three weeks would be fine, I guess. So they didn't get their census forms, among other things.
But sure, tell me how mail delivery is optional, because we all have reliable internet connections, computers, and easy access to post offices. Bullshit.
They're called public services for a reason.
Just one Week left to apply for a talk at LibreCan by LibreCan - Comunidad de Software Libre y Cultura Libre da Canaris on 30 May 2026 in Local de Canarias GoRetro in #Santa Cruz de Tenerife - Canary Islands, #Spain
