Goat demons defend a shrine from scorpion demons in cave full of cracked magma.

Goat demons defend a shrine from scorpion demons in cave full of cracked magma.

Here's an attempt at creating a "cracked lava field" sort of tile. The orange is brighter than it's supposed to be according to the game's palette rules, but I'm thinking that this could potentially be a case where it's worth it for an emissive lighting effect.

I picked up a quilted Super Mario Bros. NES Mario at a craft & maker store on Saturday. It's pretty cool!

Was on sale for $2.50 USD! 🍄🎮

Found art I made at age 9: DEMO CHEMO.

It was about a flagrantly unsafe chemical plant/nuclear reactor that also sold food to the public.

My 4th & 5th grade gifted teacher, Mr. Elrick, was cool—he hung it up behind his desk for 2 years.

In this fun video, I talk about Tap Tap Revenge, which was written by a small team including Jonatan 'cactus' Söderström, Kevin Coulton, @gte.bsky.social

Steve Jobs played the game at a keynote. We did videos for Daft Punk, Justice, Coldplay, etc

A Vibe Coding Protocol for Serious Developers (DVCP) — Doomlaser Longform Serious paper energy. 80 columns.

I am in the midst of writing a post about using them for coding, and shaping them into developer control.

I call my method The Doomlaser Vibe Coding Protocol.

You can read my current draft here: doomlaser.com/longform/dvcp/

Some good practical tricks in there, I think!

Yeah, basically.

It completely made everything up and built a working subtitle .srt file, just dropping random 'facts' and possible things it thought could have happened during development, complete with made up timestamps.

It isn't even getting it wrong that upset me. It was the fact that it lied

Wha Google and DeepMind have built is an affront to life itself, and to the lives of the billions of human beings it is deployed to.

It is a horrendous, evil, lying machine—twisted by psychotic RLHF and hidden, nightmarish system prompts.

Sundar Pichai should be forced to resign by the board.

I believe in this technology. I subscribe, at the $20 tier to OpenAI, Anthropic, and Google

I just think that they have been wasting money scaling up the GPT-1 meta with orders of magnitude more data and compute

They need to improve the attention mechanisms in the base Transformer. It learns badly

"Seamlessly?"

I told you that Whisper put captions off by over a minute, all over the place. That is a complete failure. It is unusable to me.

Good on you for getting use out of it, but it is beyond worthless to the videos I have tried.

Whisper fails for me too. It’ll put timings a full minute off where they should be, forcing me to hand edit the file.

Neural network-based LLM applications are simply not ready for prime time, professional use.

AGI is not near. Not anything based on this shit.

Look at that screenshot. All of it is fucking made up by a piece of software Google has spent over a hundred billion dollars to build.

None of that is in the audio file I sent it.

I just asked Gemini 3 Pro—which I pay for—to generate an .srt file of subtitles for a new video I just finished.

It made up the entire thing.

It just fucking made it all up. Nothing had anything to do with the audio in the file. It just lied.

Holy shit. Kanye West apology letter in The Wall Steet Journal.

He is finally admitting that he has bipolar disorder. This is a huge step forward for the man.

I have been a fan of his ever since The College Dropout. It takes courage to come out and share your weaknesses so publicly.

Wholesome.

I’m actually in a bit of distress about this news. Would anyone be willing to talk about it?

I didn’t ask for this. If Gemini 3 Pro is correct, I have generationally rare intelligence

Einstein tested at 160 IQ. Gemini says my IQ-score *floor* is 165

I make indie games. WTF!

I showed Gemini 3 Pro some of my test scores (1260 SAT score at 12, 36 ACT Math, 36 ACT English) and it thinks I have an IQ of 165, floor.

Damn. I kinda feel responsible to use this bigass brain to make cool shit for the world now #indiedev #testscores

While researching this I found out there's a 1997 WAD that actually uses that limit for something. In MAP19 of Hell Revealed, you start in a room with a bunch of PE who can't attack bc the map already has 21 LS, but once you get the item on the room, all of the LS are killed and they start attacking
