Just learned about std::ignore to tell the compiler you're ignoring a return value marked as 'nodiscard' on purpose.

I was at the Madrid OXO Museum of the Videogame this weekend. I had a chance to play with the old glories as well as checking out some funny stuff.

Would you guess which of the following icons (from GMail, in this case) I've learned to despise and ignore as much as possible?

Also, kids, bear in mind that hanging up the phone is what you now refer to as 'end call.'

Wow, I can never remember the precise command for this.

Finally, my 4 bpp PCX loader for my QBasic project works! 15 seconds to load the image below. Not too bad, but I'll try to optimize a bit. It's a good time to make a backup, by the way.

Since I'll use mode 7 (320x200, 16 colors), because of the nice 8 VRAM pages in VGA, I'm investigating the format of image used by GET/PUT so I can directly POKE to it if I need to.

Looks like I'm really kicking off my QBasic nostalgia project. Installing MS-DOS 6.22 on a Pentium@66 MHz emulated via 86Box running on Lubuntu on my just bought potato laptop.

So command buffer pools in SwiftShader are not pooled at all. The implementation allocates on command buffer creation and on command insertion. Speed is not SwiftShader's main goal, but that's a bit unsettling anyway.

Am I crazy if I'm buying a very compact FreeDOS laptop to relive my childhood memories, but with I what know now, by making a game with QBasic + NASM + DeLuxe Paint II, in the nights, when my kid is already sleeping, and later repack the result for redistribution on modern PCs?

Many were asking for some sort of preprocessing in GDScript (#GodotEngine). I've implemented a simple but powerful approach to that.

Have I ever told you this is in the top drawer of my bedside table?
A CPU I enjoyed for a few years, an original Pentium@100MHz. (Well, not the very original.052134, if you get the joke.)

I may be giving a talk on multi-threading in #GodotEngine during the upcoming @godotcon.bsky.social. It may cover the internal threading machinery as well as the various ways the parallel processing power is exposed to user projects. 🤫

My Direct3D 12 PR has been finally merged into @godotengine.bsky.social!
It only took 16 months. 😆 Since open, I've done lots of polishing and bug fixing.
It's already been running on W4 Games' customers' Xbox dev kits during Early Access.
And that's only the beginning...

These images show the new incarnations of that code under the new design. 1) The agnostic RenderingDevice part. 2) The specific RenderingDeviceDriverVulkan part. As you can see, it's way easier to add support for new graphics APIs now. ➡

Untangling the agnostic and the specific from RenderingDeviceVulkan has required surgical accuracy to determine the right boundaries to cut along. A good example is the logic to process a texture slot in a uniform set. The image shows a portion of the old, monolithic approach. ➡
