I'm in Brazil, so I'm going to get Smart TV TCL 50 inches. It comes with Linux and you can manage it via adb.

I built a honeypot for LLMs, will a agent take the bait?

The code was hand written but now Claude has refactored it. You can see the changes in git history.

Show HN: I let Claude refactor my old game

atum47 — Fri, 09 Oct 2026 11:04:00 +0000

I've been using Claude code to finish up some projects that were on hold for a while. I've been doing this in my laptop, keeping the changes local. In one session I was offered $100 usd credits to let Claude connect and work in one of my GitHub projects directly. So I chose aimAndShoot, a neural evolution game from 2019. It catched some bugs and introduced improvements. I told it I was going to post about this experience on hackernews and lo and behold, the topic was already in it's training data. It knew about the project and the fact that I hadn't addressed the feedback it got. Anyhow, I asked it to address the comments on the topic and here's the result.

Show HN: I used Claude Code to address the HN comments on my 2019 game

atum47 — Thu, 08 Oct 2026 16:40:14 +0000

In 2019 I posted Aim and Shoot here, a browser shooter where every enemy is a neural network evolved by a genetic algorithm between rounds: https://news.ycombinator.com/item?id=21353123

The thread had a lot of good feedback that I never got around to. This year I gave Claude Code the thread and the repo and worked through it:

- "Give the player full health every round" (four of you asked): done.

- "I wish there was a scoreboard, I wanted a screenshot of how far I got": the game-over screen now shows the round you reached and your best.

- "The gun sound is jarring": quieter, and M mutes it.

- "Enemies spawn on top of you and drag you around": bots now spawn at a safe distance, collisions are fixed, and there's a short grace period at the start of each round.

- "The bots all aim at the top-left corner, so camp bottom-right": this was a bug. Each bot only saw part of the game state. They now see every player, and aim, mutation and elitism are fixed too.

- "Kill the shooters first and the GA breeds pacifists" (by generation 8 they were running into walls): the fitness rewarded bots for living long, so your kill order picked who reproduced. It now rewards hitting you.

The biggest change came from a problem nobody quite named: evolution reset every time you died, so the bots never got far. Now there's one shared population on the server, and every round anyone plays moves it forward. Your browser only reports raw stats per bot; the server checks them, scores and breeds. It's PHP + SQLite on a small VPS, with a local fallback if the server is down.

It's at generation 1 right now. Whatever the bots are by tonight, you bred them.

I feel like I did that walk, in person (the tourist areas for sure). I've been to SF three times now, most of the time I'm walking everywhere. Even found a place that sells Brazilian coxinha

Gorgeous graphics. Can you talk about that a bit?

My perceptron can play this game, I think

Yeah, I saw the example with a link to GitHub and thought there would be a project. Don't like to look at code on my phone though, so I usually wait until I'm on the computer

Looks impressive, haven't looked at the code yet, I'll at night.

atum47 — Sat, 01 Aug 2026 17:21:53 +0000

Make friends. Get close with professors you like and are competent. Try stuff, reinvent the wheel. Do things manually first, automate it later. Memorize the things you know you're never gonna use in real life to pass the tests, don't go complaining like a child. Getting into to college is hard, getting out holding the degree is harder.

It is actually a Google box, at least the software is (don't know if it's modified by Xiaomi). The custom launcher gets rid of those shitty recommend videos on YouTube / Prime / Netflix...

Got myself a mi box with a custom launcher. Way better than any other Smart TV out there. Unless there's a smart tv that does not show ads right on the fing front page.

Anyway, the box is powerful enough to do several things. You can install a IP tv if you want. If you don't, you still have a pretty good media center (you can hook up an external hd on it)

There were two companies posting on hn some time ago that I suspect was just gathering training data (asking for a code challenge or to answer 2 questions about 60 seconds long answering some bs). I feel like we should denounce those as well. Posting jobs that don't actually exists. Specially those that post month after month.
