Show HN: Replicant Space – an HTTP API-based game based on the Bobiverse bookshttps://replicant.space/During Christmas 2025, I found myself burnt out from work. The last few years had been hard, and multiple redundancies saw the company I loved reduce down to just a handful of remaining staff. As a coping mechanism, I kinda disassociated for a while - throwing myself into my personal projects. AI was destroying the passion I had for coding. I tried to find some meaning in development again.After months of throwing myself into creating this game, I slowly fell back in love with coding. I taught myself a bunch of technologies that I was previously unfamiliar - Astro, Flask, Redis, Celery, Just.Anyway, this is Replicant Space. It's free. I love building and playing it. There's a cool story. Aliens are awesome. Feel free to poke the API and take over the galaxy.Jul 29, 2026 9:57 PM

Show HN: Data structures as containers – sample chapter from my Big O book [pdf]https://thebigobook.com/downloads/data-structures-sample-chapter.pdfI was a self taught software engineer that later went to grad school to get a masters in software engineering. What I learned along the way was that many of the intimidating subjects around algorithms and data structures were much simpler and less scary than I ever thought.My hope for this book is to try and help the self taught developers get on more equal footing with people who have a CS degree - at least the algorithms class - which I always thought was most important for interviews. Along the road, I realized Big O, logs, and algorithmic complexity weren't as confusing as I first thought. This book hopes to close the gap between self taught developers and formal CS knowledge - which often gave me imposter syndrome.The linked PDF is a complete chapter from the book about common data structures you'll encounter in javascript - and leaving out some of the data structures you may never see (like Linked Lists).Note - this is one chapter of the book that was published and is available oJul 29, 2026 9:47 PM

Ask HN: Looking for testers for my RAM-based Linux distributionhttps://news.ycombinator.com/item?id=49102865Hi,I have been working on a project called Invelinux for quite some time now, and now that I have released the release candidate versions, I thought about posting it on Hacker News for people to try it out.The thing that makes it stand out is its use of the Toybox userspace project, a BSD-licensed alternative to Busybox and musl C library instead of the GNU C library. It also features a very minimal framework called AMPS (Automatically Mounted Packaging System) which mounts an external drive that functions as the non-volatile storage part of the OS. System configurations, applications/scripts etc. are all stored inside the /storage/AMPS directory. Since the base system is running on RAM, when the system is rebooted, the whole system gets wiped clean. But the external storage and configurations stay intact, allowing you to load your configurations easily.To access and edit these configurations, several custom TUI tools were made so the user doesn't have to mess around in /storage/AMPS/eJul 29, 2026 8:47 PM

Ask HN: Which Jabber clients support SCRAM+ and XEP-0474?https://news.ycombinator.com/item?id=49102863Related to this thread [1] which Jabber clients not only detect MitM tampering when a valid cert is used in the middle but is not the cert on the server, meaning an entity obtained a certificate, used it to MitM the connection and the client not only rejects this alternate valid certificate but also alerts the user to the MitM. XEP-0474 SASL SCRAM Downgrade Protection (Experimental) [2] Claude does not seem to know and I can't find any clarifying documentation, just lots of open issues.The purpose is for writing an article on E2EE but I want to suggest clients that will alert on MitM tampering in a manor the person using the client can not accidentally ignore it. i.e. just click through a warningOn the server side eJabberd and Prosody appear to be the only server daemons supporting XEP-0474 but I just can't find a definitive list of supported clients even if they are in the experimental phase. they may support SCRAM+ but do not alert on tampering using a valid cert.I am not interested Jul 29, 2026 8:47 PM

Transfer context from one agent to another agent mid taskhttps://news.ycombinator.com/item?id=49102632Hello HN, If you integrate your agents with decispher you can transfer context from one agent to another agents in 2 ways -:1) If you are working on git branch then branchstory feature keeps on recording your session activity like user prompts -> agent's reasoning -> agent's action -> edited files. These recordings can be played by other agent/human taking up task next. Agents can also write handoff note for other agents.2) If you are connected using Decispher mcp then this mcp provides you a tool with copy_context and paste_context. Copy_context tools gives you a key which you use as paste_context(key) inside any other agent on any machine and your context of chat will be transfered.Try at decispher.comJul 29, 2026 8:29 PM

Show HN: Nurb – Agentic CAD for 3D printinghttps://github.com/Shpigford/nurbI've had a love/hate relationship with Fusion over the years. I can model stuff there but it's just always slow and painful and Fusion has a deep desire to crash on me.I started dabbling with the Fusion MCP a couple of months ago and found that to be a much more pleasant way to interact with it. But then I realized I was just using Fusion as a rendering engine, which was terribly overkill.So I built Nurb.You just describe what you want ("Make an adapter that connects my shop vac hose to the dust port on my table saw") and it asks for clarification, does web searches for part measurements/details and then generates an interactive viewer as well as optimized STL files to print.The whole system hangs on the convention that a part is a function, and its keyword defaults are its parameters. That concept drives the CLI, the viewer’s sliders, the tests, and the agent’s interface. There’s no schema, no project file, no init step. A project is any directory with a parts/ folder.Under the hood iJul 29, 2026 7:46 PM

Ask HN: What have you been curious about?https://news.ycombinator.com/item?id=49101448If you are anything like me, you will have about five answers at any given point in time for "What are you curious about?".Arguably, a more interesting, revealing, and kinder question is; "What have you been curious about?".I feel a looking-back-to-curiosity exercise has power to shed light on where to look ahead (and why to do it). More so, I feel it has power to grant permission to that "insatiably curious thirteen year old self" to step out and play. Because it probably already has been up to something, while your attention was elsewhere.So, here is a prompt (see what I just did there? ;-))Um... Except for LLM stuff, if you please. Just for this thread. Because these days the plurality of HN discussion appears to be about the curiosities of LLMs.(cf.

Show HN: Supapool – a Supabase per coding agent in ~400 mshttps://supapool.io/hi HN,I built supapool.io, an ephemeral full copy of supabase's services that you can spin up in ~400 ms (Auth, postgres, storage, realtime).so if you run multiple coding agents in parallel in different worktrees, they can now have their own copy of supabase without making changes that conflict with eachother.> why not use supabase docker locally?when I run 3-4 instances locally, my macbook gets hot and sometimes freezes.> why not use supabase branches?branches take minutes to setup, and are designed for persistence. this is expensive, and for a dev environment, it is too slow.> why not use mocks?mocks are bad for agents. i expect agents to test their migrations, SQL against real prod service behavior. agents hallucinate working mocks often. However, upside of mocks is that its faster and runs locally, but with supapool, the upside is less convincing.> how does it work/how is this economically viable?starting supabase in 400ms requires a few things: 1. a pool of ready supabase instanceJul 29, 2026 5:34 PM

Show HN: Wingman – A client-agnostic agent harness (written in Go)https://wingman.actorHey HN! This is a project I've been working on for a while, it's still rough around the edges but I wanted to share it and hopefully get some feedback. Wingman is a client-agnostic agent harness (written in Go). Client-agnostic means Wingman isn’t coupled to any specific problem (like a coding agent or answer engine). It’s a portable agentic runtime that lets you build arbitrary clients on top of it.So you can build a client to:- Write code- Perform automatic triage- Classify emails- Review a PRand any other LLM adjacaent problem. There are surely features that exist that aren't well documented, a bunch of small bugs/race conditions, and all kinds of things I am hoping to add in the near future so any feedback is appreciated.Jul 29, 2026 5:20 PM

Show HN: Kudory – Tailor your CV for each job applicationhttps://kudory.comI've never liked maintaining multiple versions of my CV.Every application seems to want the same experience presented slightly differently, so I kept rewriting the same bullet points and ending up with files like `cv-final.pdf`, `cv-final-final.pdf`, and `cv-final-final-v2.pdf`.I built Kudory to make that part less tedious.You upload your CV, paste a job description, and it tailors your CV to the role by rewriting and reordering your existing content. One constraint I cared about from the beginning is that it doesn't invent experience, job titles, or achievements—it only works with what's already there.It also generates a cover letter draft, estimates how well your CV matches the role, and lets you export the result using one of several templates, but the core idea is simply making it easier to tailor a CV for each application.It's still a work in progress, and I'd really appreciate any feedback—whether it's about the product, the UX, or things that simply don't work.

Show HN: Energy, carbon and water estimates for AI content, shown as rangeshttps://aicontentfootprint.com/Hi HN,I built this calculator because I noticed it's easy to know how much a LLM costs per token, but it's extremely difficult to know it's carbon footprint or power consumption. I created this as a reference based on some published papers and public information, and it helps to have a guide of the impact of photo and video generation using AI.I also added another factor about Token utilization, it's something that becomes important as the newer models start to use "thinking" modes to reach a conclusion. There is information up to earlier this year, so it's not possible to see the efficiency of newer models like OpenAI Sol or Kimi K3.All the calculator does is to provide estimations and translate them in ordinary figures so people can understand it. There is no login required or any other type of paywall.About the models, it's easier to make estimates for Open Source models (of course) so there's more confidence on that data. For the closed ones, there are estimations based on public aJul 29, 2026 4:29 PM

Show HN: Kedge – Full-stack cloud with forkable VM snapshots and global SQLitehttps://kedge.dev/I'm building Kedge, a globally distributed platform for stateful serverless apps. Here's how you make a simple static site: `echo '# Hello world!' | ssh kedge.dev`I helped build Fly.io for 4 years and shared enthusiasm for the founders' vision of a 'global Heroku'. While there, I wrote "The Serverless Server" (https://fly.io/blog/the-serverless-server/) as a study of Lambda and a sketch of a modern serverless product built around lightweight VMs. That essay was the initial inspiration for Kedge.Kedge has a fast VM orchestrator that can create code sandboxes or scale service instances in 3ms, using a combination of forkable VM snapshots and a tree of warm pools (Linux kernel -> base runtime -> app). VMs are memory-dense thanks to shared copy-on-write memory pages. You can run lightweight CGI-style functions, public OCI images, or source code for BuildKit to compile and deploy.Kedge's global control plane sits on an eventually-consistent SQLite database.

Ask/Tell HN: use the flag button instead of complaining about AI slop articleshttps://news.ycombinator.com/item?id=49099039There is an article sitting at 60+ points now at the homepage which is clearly written by an AI and most comments saying something along the lines "this article is clearly AI slop". In this particular case, the article seems to be real AI slop: it creates a nonsensical benchmark to compare two tools and uses that to plug the company's product. The people commenting are right to point it out.The problem with the repeated complaining about AI slop is that it makes browsing HN tiring for two reasons: the community is failing to filter low-quality content, and on top of that we end up with a barrage of similar-looking complaints in the comment section.Both of these problems could be solved with one single action: flag articles that are in clear violation of the HN guidelines and move on.The quicker these AI slop articles get flagged, the lower the chance they get to show up in the front-page and the less incentive there will be for vibe-bloggers to push their crap here.Jul 29, 2026 3:48 PM

Ask HN: My domain registrar rug-pulled me for $3000 [fixed]https://news.ycombinator.com/item?id=49099021I registered the domain onlyfans.sexy ~6 years ago as a gag where I'd post pictures of fans (everything on the site and in this post is SFW). This year I got an email stating that, like all prior years, the domain would auto-renew at $38 in seven days and didn't think anything of the next two emails also notifying me that the domain would auto-renew.It would seem that I very much SHOULD have paid attention to those next two emails, because in both the three and one day renewal emails the price changed from $38 to $3000. Needless to say, I was surprised when I was billed $3k USD (plus tax).After contacting Hover's customer support, they told me that there was nothing that they could do about this and they have a no refund policy because "Hover does not have the ability to override or reverse pricing set by the registry.
