Show HN: RDST – A local agent that watches Postgres/MySQL for query regressions We noticed during the course of many many years of DBA related work that fixes to database issues and queries are always reactive. An entire database can fall over extremely quickly when an unbounded query grows without warning. Traditionally, DBAs hear complaints of slowness and follow a methodical process: - manually browse pg_stats or other database related performance internal tables - see which queries are slowest - figure out what indexes are missing - figure out which indexes are actually bad and slowing down writes - painstakingly implement a fix In the age of cheap intelligence, we decided that there is no reason we can’t have an always-on agent that is designed to do this job for you. Databases need something or someone that is always watching with a massive amount of contextual understanding to be able to take quick actions. We’ve watched the alternative play out repeatedly. One of our users’...

Show HN: Dub Anything – Dub videos in each actor's own voice There are many movies and shows out there with neither subtitles or dubs in English (or any other language). Pretty much impossible to watch. With SOTA AI now directing the process, you can do it locally on your machine. You basically just clone the repo, open up Codex or Claude and tell it to dub the video you want in the language you want. The repo contains all the scripts and guidance I've developed over the past few weeks to create dubs that are watchable, as an added bonus the voices in the dub are the actors own voices which is really nice. Also it's self improving, each dub may modify the scripts for better fidelity. So feel free to push them back to the repo so everyone benefits. Thanks. https://ift.tt/yAdl5no October 15, 2026 at 01:19AM

Show HN: Petal, open-source CoScreen/ScreenHero finally free Hi HN! I’m Jason Thomas, one of the founders of CoScreen. As some of you may know, Datadog sunset the CoScreen service on July 31st. Four of us from the original CoScreen team have spent the last couple months building a free and open source pair programming tool inspired by those that came before us: It’s called Petal ( https://ift.tt/kbDzYft ) Some history first, because when we started CoScreen we had hoped to break the sad and established pattern of this industry. Screenhero was an exceptional tool that a lot of us loved for pairing. Multiple cursors, low latency, you could click your partner’s editor, and just start typing. It felt like magic while we had it. Then Slack bought it in 2015, and shut down the standalone app in December 2017. When Till, Max, and I started CoScreen, we were aware of this history, and wanted to build an even more magical collaboration and screen sharing experience: the entire concept was “thro...

Show HN: Factory DS, A Factorio-Like Game for the Nintendo DS Hi HN, I'm Ronan. I love the Nintendo DS but ran out of games that kept me hooked, so I tried porting the kind of game I play today: a factory game in the spirit of Factorio, on a 67 MHz ARM9 with 4 MB of RAM. I had never written code for the DS, and I built it with Claude Code. I wrote the specs, the design and the balancing, and Claude wrote most of the C. The post goes through how that worked, and through the technical parts I found the most fun: - a 2048x2048 world that is never stored: terrain is computed from (x, y), only the player's changes are kept in a hash table - night done by changing the 256-color palette instead of redrawing the screen - power grids and pipes computed per network with union-find (there is a small step-by-step animation in the post) - trains with schedules, block signals and pathfinding, plus redstone-like logic gates - a headless Mac build of the game with a text interface, so AI agent...
