Just learned that there is no way for a GLSL shader to send data to the CPU side program.

@kertinker @landelare it occurred to me just now if there's an explicit GL context initialization step needed that is missing entirely, then GLEW might be reporting 0 for most or all extensions depending on the platform you're on
@aeva @kertinker This crap is why I'm using DirectX.

@landelare @kertinker as it happens, Windows is the really weird one for GL

@landelare @kertinker granted they all have quirks, but that's the tradeoff for not being shackled to microslop

@landelare @kertinker not to imply that d3d doesn't also have its own problems, but I don't think it's especially helpful to dunk

@landelare Can't blame OpenGL in this case. @aeva pointed out I missed an initialization function, in GTK not OpenGL, so it would have failed even if I used DirectX. Looks like the problem is me not reading the documentation correctly.

@kertinker @landelare I'm not familiar with GtkGlArea, but I spotted this in the docs https://docs.gtk.org/gtk4/method.GLArea.set_required_version.html
You have to call gtk_gl_area_set_required_version before the widget's rendering context is created, but I imagine if you set it to 4.6 (based on your earlier visualinfo paste) then you should be able to see the extensions you are missing. Ideally you'll want to set it to the lowest required version you need, but 4.6 is fine for debugging.
@aeva Huh, it must default to a really low version, which is why so many extensions say they're unsupported. Thanks so much! I'll go try it right away.
...
Yes, all extensions except ARB_vertex_program are now supported!

@kertinker @landelare these things happen, but we got it working :D

@aeva @landelare Now my cludgey pointless geometry shader draws a box *three* times!

Una cattiva gestione è un problema tecnico e amministrativo. Una strategia che lascia maturare lo scontro per rafforzare una narrativa securitaria o per delegittimare un movimento è una scelta politica.
Quando manca l'assunzione di responsabilità sul piano politico, la vuota e ottusa cronaca resta l'unico ambito in cui le narrazioni ufficiali sono costrette a confrontarsi con prove, testimonianze e contraddizioni.

@ricardo ahah sure. That's the only point of the house where I can get some weak 5G signal

@af I think they're using one of those agents, unattended. I've already experienced it - companies claiming, proudly, that they don't need first level anymore as they have AI agents. That's why I tried to escalate, but I'm starting to think they're refusing (better - ignoring) as there's nobody to escalate to...
