It’s incredible how smoothly Fortnite runs when I’m playing with friends across the US and Europe, with everyone on different hardware, from high-end PCs to mid-range Android phones. Everything just works flawlessly. I honestly can’t think of another game that pulls this off so well.

No, as long as it’s fun and I can easily refund it if I don’t like it. If an AI-generated game fits my vibe, I’ll happily buy it and play it.

Just added smart hints to my GobNative engine for the 1991 classic Gobliiins! 🧙 I always loved these games, but some puzzles were ridiculously hard. Now the game tracks your progress and gives you little hints when you're stuck, without spoiling the fun! games.encrypted-cat.com/devl…

Hi @webkit, is this expected? 🤔 Same iPhone 15 Pro Max (iOS 27, Safari), same page from my Mac:
http://192.168.x.x → JS ~8× slower, WebAssembly ~20× slower
https:// → normal speed Lockdown Mode is off. Is the JIT disabled on non-secure pages now? Documented anywhere?

The other half was my own code: • stepped Rapier's pipeline directly (no soft bodies to sync): 1.76 → 0.08 ms • 21 → 5 lights in every shader • debris goes static after landing Lesson: test phones over https.

My @threejs + @dimforge Rapier game ran at 2–3 fps on an iPhone. Now it's a locked 60. Plot twist: I'd been testing over http:// On a non-https page, iOS Safari turns the JIT off for JavaScript and WebAssembly. Same phone, same page over https: physics 20× faster.

Amazing work! Really impressive results. One small suggestion: some images are brighter than others, so automatic exposure and white balance adjustments could help make everything look more consistent.

Update: Removed all unnecessary apps, blocked all ads, and figured out the controller issue. Everything works perfectly now! Took me just 5 minutes with Claude Code

Old devices that are no longer officially supported could get a second life. I rooted my LG OLED TV and installed RetroArch, but Bluetooth controllers don’t work properly with it. I’m wondering if there’s a way to fix that. The TV still has a fantastic OLED panel, but its software hasn’t received updates in years. It’s a shame to let perfectly good hardware become obsolete just because the manufacturer stopped supporting it.

I'll probably make the repo public. You need your own copy of the games (on GOG); no game files included. I won't share my remastered art, but the repo has the whole pipeline: export the art, repaint it with an image model (OpenAI, FLUX, Qwen), load it back as an HD pack.

It also runs Gobliiins (1991) and Goblins Quest 3 (1993), all three played start to finish by automated test scripts. Native on macOS for now; Windows and a browser version are next.

ScummVM already runs it great. Mine adds: • HD remastered rooms, pixel-aligned to the original • sharp HD text, CRT/xBR/smooth filters • enhanced sound effects + replacement music • level select, quick save/load • 1.2–2× speed, skippable cutscenes • in-game overlay

I vibe coded a native runtime for Gobliins 2, the 1992 Coktel Vision point-and-click puzzle game 🧩 No emulator: it reimplements the original engine, using ScummVM's code as the reference (huge thanks to them). Before → after

Good large codebases are broken down into smaller, manageable pieces so humans can understand them. If a human can understand each piece, why wouldn’t AI be able to do the same? And if a codebase is so complex that even humans can’t understand it, that’s a problem with the codebase, not AI

Building software is getting easier, sure, but distribution, trust, community, and infrastructure still matter. You can clone Facebook or Instagram with AI, but that doesn’t mean millions of people will suddenly start using your version. Building the app and building the business are two very different things

The same people asking "did you write it yourself?" built entire careers on a Stack Overflow answer from 2013 and a comment that says "don't touch this, it works."

Потому что я смотрю YouTube на разных устройствах: телефоне, ай паде, телевизоре и даже в машине. И далеко не на всех платформах есть возможность установить модифицированный клиент без рекламы.
