> In this case, the only "manual work" I did was: 1) I had to create some kind of API key from Google Cloud UI to query YouTube for video metadata, 2) I booted up a VPS box and 3) I bought the domain name.

i stopp doing these things, too. I use browser-harness to do all of these things. Always trying to keep myself out-ouf-the-loop.

fixed. But, now you have to upload your own ROM. (Afraid of getting DMCAed by Konami)

I added audio support, but now you need to upload your own ROM. I didn't expect this to get so much attention. Since Konami is company behind Contra and they are known for DMCAing, i want to be better safe than sorry.

Bear in mind: the dissambly was done pre-LLMs. The early commits are from 2023. Although, ChatGPT 4 existed then, it was not capable of doing these things.

Impressive work, indeed. vermiceli the GOAT.

For the Multiplayer part: It's deterministic lockstep. Both browsers run the same C core (compiled to WebAssembly), and the only thing sent over the network is each player's button bitmask per frame. Local input is delayed by 4 frames (~67 ms), which hides normal internet latency; if the other player's input for a frame hasn't arrived yet, the game waits for it. Every 2 seconds both sides compare a hash of the game RAM to catch desyncs. Transport is a WebRTC data channel via PeerJS (its free cloud server handles matchmaking with a room code), with Google's STUN server for NAT traversal and Metered's free-tier TURN relay as a fallback when a direct connection isn't possible.

For AI usage: It was all done by Claude/Codex, but it wasn't that straight forward. First: i started in April and the models weren't good enough and would make errors. You could see those immediately in glitches. Then, i spent some time in building a harness and collect telemetry data in Mesen. Once, i had that: i just played the game in the emulator and asked Claude Opus 5.5 to use this as verification. The rest was smooth.

Based on vermiceli's annotated disassembly of Contra: https://github.com/vermiceli/nes-contra-us. Thanks for the great work.I ported it in two steps. First to C: the game logic is translated routine by routine from the 6502 assembly, and checked frame by frame against the original in the Mesen emulator. Then the C code to WebAssembly so it runs in the browser.The cherry on top: online...

Re:CS336: Language Modeling from Scratch on Monday June 01, 2026 @07:46PM (#48364064)
Couple days ago, i used Claude to implement an improved version of gpt-1. I am no ML Engineer by no means. I am just a normal backend engineer. I ended up creating a hybrid between gpt-1 and modded-nanogpt (from KellerJordan).

I was able to reproduce the results of the original gpt-1 paper with my gaming PC. I don't even have alot of VRAM. My NVIDIA GeForce RTX 2060 SUPER was able to reproduce most of the results with just 1 hour of training. I would totally recommend to do the same, if you are interested in pre-training LLMs.

The code is here: https://github.com/epoyraz/modded-gpt-1 But, you can also just ask Claude 4.8 or Codex 5.5

Thank you for your kind words. Yes, i hate subscriptions. But, also. Renovating is a one-off thing and i can't justify charging a monthly fee for a service that is only needed once.

This is one of the reasons people love using xona: no subscriptions :)

Re:I solved almost all of free problems on LeetCode using AI on Tuesday May 20, 2025 @06:48PM (#44046701)
i was thinking the same. And i am sure it is in the training set, but i couldn't solve 10 hard problems. Also, most of the hard problems, the LLMs weren't able to solve in one shot. How do you explain this?

Hey Guys,this is my little pet project. The motivation was: i hate writing cover letter and i want to automate is so much, that 9 out of 10 coverletters will be ai generated in the future.Let's flood the market and recruiters will simply stop asking for a cover letter. I don't want to make any money out of it. It's free. You don't need an account and it's available in 32 languages. Would love...

I'm working on Xona AI (https://xona.ai). I want to democratize the generation of 3D visualizations for interior and exterior design. We will launch next week on ProductHunt :)

Very excited.

just look at switzerland. They have direct democracy and they don't have a problem with corruption at all. Why you wouldn't want that?

Polictians are a thing for the history books.

Also: In Switzerland, you don't HAVE TO vote. You can vote. It's optional. It works. Just open your mind, man.

from the ask-hn dept.

Hi there, i always asked my self, where there is no app, that solves democracy. Why are we still voting every 4 years. Going back to first principles, we should ask ourselves : Why do politicians exist? They existed(!) in ancient greece, because people didn't have time to inform themselves, right ? - We solved this with newspapers, 100 years ago. Ok, but we can't sit all day in parliament,...
