Yeah the subscription economics will 100% change, but that is different from AI dev going away. Ignoring running it locally, inference costs did go down from $20 per million tokens in 2022 to something like $0.07 in 2024, subsidized like CRAZY but trending downward hai.stanford.edu/ai-index/202...

For sure nobody is shipping unverified AI generated RTL, but I know first hand that AI is in the workflow already with folks at Google / DeepMind from people who are already using AI for RTL, verification, optimization and chip layout, albeit with extra rigorous signoff.

I'm sure there are corners of the world it hasn't impacted yet, but nothing in the corporate world is untouched. The unfortunate reality is the frontier models are good and if you already have the skill to accurately describe what you want, your job is safe but you now manage AI rather than code.

I don't think most folks are aware how ubiquitous AI is in software engineering. I've interviewed at over 20 different companies, all have moved to AI driven development, ranging from FAANG / MANGOS to 3-4 person startups. Love it or hate it, it is here and you are either using it or changing jobs.

Just about ready to be done with the SNES assembler I have been working on for 3 years. Wrapped up ASAR support and ca65 support; added a LSP (language server) so VSCode and all the forks get nice source code information for references, rename, refactor, and much more!

SimCity SA-1 makes the map generation process much faster. From over 10 seconds to less than 2 seconds, picking and generating a map is a much better experience.

Gotta nip this in the bud: These games are not unaccounted for. The ICS's collections were owned by the Computerspielemuseum and the USK ratings board. They still own them. This museum project is on the cusp of shutting down, but the games themselves are not going to a dumpster

The "capitalist just keep pushing capitalism" takes come in many flavors. The "big one" of the moment is the never own always rent digital economy around video games, hot on the heels of GTA6 being more expensive. Feeling a lot like we need a 1969 Panther movement given all the changes happening.

RIP Bobby Prince. His music legacy will live on, making inspired music for Commander Keen, Wolfenstein 3D, DOOM, countless others. A true legend. And such a nice man, great musician, wonderful, fun-loving man, nothing but happy memories of him. A loss to the world.

Seeing this all over, from 20 person companies to 1,000s. Across multiple industries. People are being measured by their adoption of the tools and understanding of how to use them. Really curious how far this reaches both inside engineering and outside engineering teams.

Is there anyone working in engineering that is not using AI via Cursor, Claude, Codex, etc., everyday? Engineering has largely changed from a "writer" role to a "editor" role overseeing agentic output. Interviews are about how well you use AI, not wasting effort trying to detect AI.

What I understood from the call was it's like learning situation, and I already was a client and I think male models for that particular procedure are rare, I don't even typically do that just "inner backside", and the whole thing was so funny to be the guy to get called.

Got a call mid meeting from my esthetician asking about being a male model for a Brazilian wax, and if I would be comfortable doing that & being observed. Of course I would, but I literally had to pull my pants open and check the length which felt so cartoonish, the whole thing was hilarious. 🪒🕯️🇧🇷👙

The "Pro Fighter X" series of SNES copiers has kinda stupid disk handling code: it doesn't filter out FAT entries on floppy disk that should never be displayed, like the Volume name ("CHRIS"), directories, and long filename chunks. This causes errors during display & loading. So I RE'd and fixed it.
"Pro Fighter X" SNES copierIt's displaying the volume name first, "CHRIS" then overlaying invalid entries into the file list. Also tries to load invisible files...My disk fix code. Done through a bit of searching and trial-and-error, since these BIOSes don't run on emulators, and no SNES emu emulates floppies anyway...Pro Fighter X file display fixed up!  Also with a new tilde glyph added into the font, as well as a new custom SFC background

Hot Take®™, there are bigger issues to deal with than using AI to make something useful. It is the same sort of vitriol people contributing nothing direct towards well meaning people for social issues. Your selective adoption of technology doesn't make you a saint, as using AI doesn't make you evil.

Gaming Alexandria is our load-bearing pillar for access to Japanese scans and hubz is the hardest-working guy I know in game preservation, so I'd really appreciate it if we didn't destroy him with a dogpile over his vibe coding project please. Show some empathy and grace if you disagree with it.
