Show HN: Open-source verification and tuning layer for self-hosted LLMshttps://github.com/colomalabs/colomaHi HN,Thomas here, I'm a Machine Learning, and I've been deploying models in prod for the last 5 years and decided it was time to open-source some of my learnings!In Coloma you'll find my vLLM tuner, I use it to ensure models don't OOM at runtime, and are optimized for the metric that matters the most for that deployment: low per-user latency vs maximum system throughput. To make it easier the dashboard ships with an estimator of the performance expected at runtime depending on the parameters picked.I've also started to add my outputs verification system that triggers when the GPUs are idling, so that at runtime the predictions can run fast, and get flagged later on for continuous improvement.Really looking forward to see if it that can help someone!Jul 17, 2026 5:03 PM

Thanks HN for 15 years of support and helping me find my life's workhttps://news.ycombinator.com/item?id=48949551Tomorrow is the 15th anniversary of the first day of the Recurse Center (https://www.recurse.com/)My cofounders and I did YC all the way back in the Summer of 2010, with the initial idea of building "OkCupid for jobs." That idea quickly fizzled, and we spent the better part of a year pivoting between other ideas that also failed.Finally, we made something that we wanted ourselves: a self-directed programming retreat, where people built fun projects, contributed to open source, and helped each other become better programmers.After running two small batches, we launched on HN[1] and got an incredible reception.That post on HN helped us reach beyond our personal networks and meet programmers from around the world, many of whom have since become friends. HN brought us the majority of people who came to our next few batches, and in the years since, HN has remained our #2 source of applicants (after word of mouth).Alas, pg's comment[2] on HN when we launched turned out to be prescient: RunniJul 17, 2026 4:57 PM

Show HN: Da Ultimate Rap Battle: 564 dope-ass rap songs, rankedhttps://ryantuck.io/rap/Hey HN, this is a world cup-style tournament for over 500 rap songs I've saved in my liked songs in Spotify over the years. It was really fun to work on!Lots of good stuff from NWA, Jadakiss, Lil Wayne, Jay-Z, Big Pun, Eminem, Nas, and more.Tournaments are a good way to separate the wheat from the chaff in any high-dimensional space like music, and it's really fun to have no idea which track's actually gonna take the top spot until it's all over.As a mostly-backend/data developer for the past decade, it was my first real foray into pixel-perfect frontend and was completed last year before the AIs conquered the territory. Flexbox is fairly intuitive and frontend is quite satisfying!Structure was a series of 4-track group rounds (top 2 advance) followed by a 128-track head-to-head bracket.Knockout round: 564 -> 512 tracksSquad Round 1: 512 -> 256 tracksSquad Round 2: 256 -> 128 tracksBracket Round: 128 tracks -> 1 winnerClicking on any track tees up a preview in the embedded Spotify miniJul 17, 2026 4:56 PM

Show HN: Justif – Knuth-Plass justification and microtypography for the webhttps://justif.lyall.co/Justif is a drop-in JavaScript library that progressively enhances web pages to TeX-level text justification. Installation is a single line, standard text and accessibility affordances are unchanged, and users with JS disabled get native browser rendering.I made justif because I've long been a fan of justified text. I think it looks clean and elegant, and makes reading more enjoyable. But bad justification is the opposite, with gaping spaces that distract me to the point of making the text near unreadable.Browsers have got better recently at handling justified text [0][1], but still use suboptimal greedy algorithms for the most part, and are not near that TeX/InDesign level of quality that I crave. `text-wrap: pretty` exists but is far from a panacea, as you can see for yourself in the demo.Justif also has the benefit of providing more consistent text layout across browsers. Blink (Chrome), Gecko (Firefox) and WebKit (Safari) all justify text differently, so normally what the user seesJul 17, 2026 12:47 PM

Show HN: Vulnsy – A platform for vulnerability management and reportinghttps://www.vulnsy.comI've spent over 10 years doing penetration tests and red team engagements, and one thing that always seemed to take far longer than it should was reporting.Most reporting platforms do a great job of managing reusable findings, but I still found myself digging out old reports and copying the same narrative sections over and over again.Many engagements contain pages describing methodology, attack paths, privilege escalation and post-exploitation that only need small changes between clients. I wanted those sections to be just as reusable as findings.I built Vulnsy to make the entire report reusable. Alongside reusable findings, you can build libraries of narrative sections, assemble reports quickly, customise them for each engagement and export professional reports without copying content between Word documents.There's lots more you can do too..Jul 17, 2026 11:02 AM

Show HN: OSS Pi Agent for Slack and Linearhttps://github.com/brainwavesio/pi-digbyWe've been using a now-discontinued version of pi-mom from the pi monorepo for a few months now. Digby is a slackbot which you can also assign Linear issues to. It has a private (Sign In with Slack, locked to your team) wiki and can serve raw assets. It's pi, so it's self-modifying and self-improving.This isn't enterprise-grade, super secure stuff, but really a pi session anyone can use and one can works really well. Out of the box it deploys (and redeploys itself when PRs merge) itself to AWS on a small container. Runs on Claude Sonnet on Bedrock, but can use any Bedrock model easily. If you give it a Github token it'll open PRs to your codebase on its own behalf (or whoever owns the token -- very much advise you give it its own account). It can sign you into MCPs, and open its own browsers using Browser Use. Most importantly, it's very easy to fork and extend and make your own.We've been slowly improving a lot of the sharp edges the original pi-mom came with, to the point it's usableJul 17, 2026 6:14 AM

Show HN: Deadly Dispatch – A physics puzzle game 13 years in the makinghttps://store.steampowered.com/app/4890070/Deadly_Dispatch/Thirteen years ago, I had an idea: build a bomb from different stages and materials, call in an airdrop over a zombie-infested city, and let physics do the rest. Set off chain reactions through fuel stations and car wrecks. The catch? There are survivors down there too, so every strike is a balancing act.I’ve always loved messing around with physics demos, and in my head, the core loop was already fun. So I built a few prototypes, but none of them stuck. I never clicked with Unity, and every attempt eventually died.Every couple of years, I’d check the App Store, Steam, or just search online to see if someone had made it yet. I wasn’t worried about being scooped. I wanted to play it, and I didn’t care who built it.This year, I started another prototype, and it immediately felt right. Then one thing led to another: I built a level editor, experimented with a bunch of levels, and the whole thing kept becoming more real.Now I finally get to share this crazy idea with you all.It’s called DeJul 16, 2026 11:12 PM

Ask HN: cybersecurity refusal for turning a jailbroken kindle into a monitorhttps://news.ycombinator.com/item?id=48940976Asking from a place of curiosity.I wanted to make a project where I upcycle an old kindle into an e-ink monitor via USB-C tether.The jailbreaking process is extensively documented, but I wanted something custom to have a small local process push text like emails and terminal output onto the kindle with custom typography.For me, the custom typography thing is the important bit as most type rendering on most e-readers feels bad / stale (at least to me). And I want to understand how font rendering works from the firmware up.I tried to ask Fable to help me, but it refused. And then so did Opus; Fable 5's safeguards flagged this message.

We're Giacomo and Roberto, authors of Ratel (https://github.com/ratel-ai/ratel)We used to help SaaS companies build agents on top of their products. Whenever we wanted to expand the agents’ complexity/scope, by adding more and more tools and instructions, we always run in the same issue: context bloat, with frequent hallucinations and sky high token bills. So we started constantly engineering the agents, dynamically loading tools, splitting them into subagents, inventing our own way to support skillsAnd that's exactly when we started building Ratel: a library to let your agent keep its full catalog of tools and skills, but progressively disclosing only the few that actually matter for each turn.

Show HN: Leaves – A text-UI disk usage treemap visualizerhttps://github.com/patonw/leavesGUI disk analyzers are great for figuring out what's filling up your laptop/desktop drive.On containers or remote servers, the options are limited to purely text based utilities (e.g. du) or list-centric TUIs (e.g. ncdu) which are usually limited to viewing one directory at a time.I created leaves to fill that gap.Inspired by classic utilities like WinDirStat and KDirStat, it uses a 2-dimensional treemap^1 visualization to show the entire directory hierarchy with proportionally sized rectangles.It's performant enough to handle millions of files, thanks to Rust and multi-threading. However, block characters aren't as suited as pixels for resolving a large number of items. Leaves can show file-type summaries per directory or partition the top-level directories by extension, allowing you to see not only where space is being used, but also how.For instance, I can see the largest chunk of my home directory is taken up by uv caches for python and old Linux ISOs that I could easily re-downloaJul 16, 2026 4:03 PM
