Yo waddup~ Here's an update video that I've made for my PSX-styled 3D platformer that I've been working on in my renderer, Tetra3D. This update focuses on the UI stuff I've been working on. youtu.be/BdY55w0_gpE #gamedev #tetra3d #ebitengine #psx #retro #golang

finally got the shader looking good, even if by accident lol. Probably a sign to stop working on it for a while and focus more on game design. #cloudbusters I've also got to figure out how to tell the story... lore dumps as rewards? in game wiki? #puzzle #indiegames #gamedev #ebitengine

In Plan 9 in ~2001, we introduced "private" processes that even a sysadmin couldn't access, debug, etc. I just learned Windows Vista added the same in 2007. The difference? We did it to protect keys held by the security agent, while Windows did it to protect media content. Priorities! ¯\_(ツ)_/¯

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software. Just fuck you. Fuck you all. I can't remember the last time I was this angry.

to me

Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

For this game i don't think i'll include classic boss fights. Instead, i'm leaning toward encounters like this one: a single foe that requires learning how to defeat it, while keeping the idea that every enemy still dies in one hit!!! #screenshotsaturday #ebitengine #gaming #indiegames #pixelart

A new weapon: Splitter A direct hit does a small damage, but every next split increases it like 4->6->10, meaning it is much more effective when not aiming directly at your target. The bots are programmed using the in-game behavior configuration #indiegame #indiedev #pixelart #ebitengine #gamedev
