#312Built this 18 years ago. Flash arcade game engine. 10,000+ games built by users on it. 2+ million plays. Lets you build mashups of classic arcade rules like Breakout+Space Invaders as one example.
It's been unplayable since Adobe killed off Flash. It uses a lot of dynamically loaded remote assests so Ruffle hasn't been able to run it.
Recently had Claude Code fix the Flash client so it would work in Ruffle and then had it convert the code to haxe (let's call the haxe version v2). It was an interesting conversion because Claude made a lot of wrong assumptions about how the engine worked so had to have it test every feature and match parity between the ActionScript version and the haxe version numberous times and play test it all. It's pretty close to parity now but still ironing out kinks in the engine. The existing engine art is very 2010esq.
On the game editor side converted it (it just re-wrote it) from ASP into JS. Now with an AI agent to help configure the settings and generate fresh artwork in additional to the manual editor.
The art has some very specific rules about orientation etc which the pixel art generation models seem to struggle with a bit but getting that aligned as well.
It lives again!

#313my goal is to offload phone videos (to free up device space) and persist them in self controlled storage. the convention makes this significantly more useful than a collection of object paths

#315Parliament of Owls, Pounce of Kittens, Murder of Crows - the terms of venery are for animals.
But what about other things?
What do you call a group of Roses, or Snowflakes, or Lawyers?
Well, I couldn't figure it out, so I put it to a vote.
Simple ELO scoring, Endless mode is always on, and there is a Daily Contest for you to compete in (Wordle for wordsmiths, I guess).
I'd love to hear any and all feedback on it.

#316I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control. Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI…

#317It's mountaineering safety tool I've been making for my friends and I.
The fun part: if your browser has WebGPU, the page solves that field live as a compute shader (about 35 ms on an Apple GPU) as you scrub the timeline, and draws the flow over a 3D terrain view. Browsers without WebGPU get a precomputed field.

Ranges and uncertainty only, no go/no-go verdicts. That still requires your best judgement as a mountaineer. Next up is a free-play mode where you set the wind direction and speed yourself and watch the field re-solve.

#318I appreciate that it makes me revisit some math which i've forgotten like directional derivative and why gradient points to highest ascent.
Interesting but hard as well.

#319My grandfather and uncles have left me a vast pile of Urdu magazines and books, many of which are withering away due to old age. I’m working on digitizing them so I can enjoy them on modern devices. Very much in initial stages. https://nashist.naiyerasif.com
