Show HN: Real-time n-body tree code in CUDAhttps://github.com/lechebs/nbodySharing an old project of mine, on my RTX 500 Ada laptop GPU, it can simulate up to 4 million particles at ~400 ms per step using the Barnes-Hut algorithm, saturating the 4GB of VRAM available.The octree construction is fast, as well as the traversal. The major bottlenecks are the VRAM usage (1 million bodies require ~1GB), which could be probably halved by reusing intermediate buffers, and the particle to leaf evaluation, which would benefit from more fp32 FLOPS. Moreover, I still don't have a good heuristic to predetermine the size of the BFS queue, perhaps some sort of memory paging could solve the issue.Jul 10, 2026 3:47 PM

Show HN: Postern, an email system for both humans and agentshttps://github.com/skyphusion-labs/posternHello everyone! I wanted to introduce you to a new project of mine, postern, which is an email system for both humans and agents. You can give your agents their own email addresses, the ability to respond to emails if you want, and all emails are presented in one nice unified mailbox. The email stack runs on Cloudflare Workers (email sending does require a subscription to the $5/mo Cloudflare Workers Plan), messages can be ingested into Vectorize (this is optional) to allow your agents to easily retrieve information and answer your questions about your email, attachments are stored in R2, and message state/contents are stored in D1. There’s also a RFC compliant SMTP relay server that runs on your server to translate anything that speaks the 1982 SMTP RFC spec into API calls so you can send emails from your server through the postern stack. There’s a python based IMAP proxy which allows you to use any client (tested extensively with iOS Mail, Apple Mail, Thunderbird, and Evolution) as wJul 10, 2026 2:34 PM

Show HN: Mojave Paint for macOS, edit images like it's 1999https://mojavepaint.app/We all need a swiss army knife for images. A tool for really getting in there and dealing with the pixels precisely. You might be combining images into a sprite sheet, you might be matting images to squares, cutting out solid backgrounds, re-tinting graphical elements. For a website, a video game, for an app.There's a million photo editors, there's a million design tools, and Mojave Paint can do those things in varying degrees but "graphical asset production" is its first and primary mission.It's cheap! $9.99 (one-time, sad I even have to say that) for the "Pro" version. It's Mac-only, and Apple Silicon Mac at that. Does it look a little like Photoshop 5.5 from the year 1999? Maybe a little but also it's got plenty of its own original ideas. (Blog post on that is forthcoming…)I've always been passionate about image editing tools for the technically-minded so I'm throwing my hat in the ring in that space. And sure GIMP is for the technically-minded but boy is it ugly on the Mac!Jul 10, 2026 12:29 PM

Show HN: The Flint Programming Languagehttps://github.com/flint-lang/flintcI am happy to finally announce the language I have been working on for the last 2 years, [Flint](https://flint-lang.github.io)!Flint is a high-level, statically and strongly typed, compiled language which centers around transparency as its core pillar. The compiler is entirely written in C++. It originated from one simple idea and core concept:> What happens when you center the whole language on an ECS-inspired composition-based paradigm?And so the journey began. The core idea is simple: data and functionality are separated and then composed deterministically into larger entities. This idea is not new at all, ECS exists since a long time. But a composition-based workflow can only be "emulated" in Object-Oriented languages and I find it often painful or unergonomic.In Flint, composition is the core paradigm. I have put great effort into making it ergonomic and "just work". The result is a system which can be described as a cool mix of OOP and ECS. I gave the "new" paradigm a name, sinceJul 10, 2026 10:59 AM

Show HN: Vuci – make the spoken word searchablehttps://vuci.ai/feed/hi, I'm Reuben Over the past few months I've been building a platform where all the information is sourced from spoken conversations, and I wanted to make this content searchable, savable, and shareable. Presented in a well-designed format, similar to Yahoo but with higher IQ content.Like most, I listen to a lot of podcasts, but I wanted to connect the dots on different topics and read the parts which are interesting more deeply. Sharing bits and pieces with friends was also a motivating factor, as well as alerts which feed into my other pipelines.That said, I'm not sure which parts of the platform will resonate with users or not, so it's an experiment in progress.Technicals: I love my craft (both design, and code), so I took ample time to think about UX and design it in Figma. It's cookiecut from ample projects I have in Django and HTMX, and scaffolded my way through. Hosted on Digitalocean, and AI agnostic from an LLM perspective. I can go deeper into these, but they probably deserveJul 10, 2026 9:10 AM

Building a real-time AI tutor for 5-year-oldshttps://www.ello.com/blog/teaching-a-child-in-1000-msHey HN! We've spent the good part of this past year building an AI tutor that teaches kids ages 4-9 reading, math, ESL and more. Getting an AI tutor to effectively teach a child turns out to be a really hard technical challenge, this took getting the underlying architecture right.Our tutor steers the UX in real-time and makes complex decisions on the fly. Doing both at conversation speed required us to replace the standard tool-use loop. We built our own tutor harness that utilizes a streaming interpreter that executes actions, while an asynchronous planner model reasons ahead of the conversation and makes calls that drive the child's learning. On top of it all, we developed a safety system that checks every turn without it causing an interruption to the activity and conversation flow.Effective teaching isn't just about answering a child's question quickly, rather making the right move at the right moment. AI is also going to be an integral part shaping how this generation of kids learJul 9, 2026 8:51 PM

Reality of Commercial AI World from a 16 Year Old's Perspectivehttps://news.ycombinator.com/item?id=48851812Let me tell you who I am first. I'm 16, a mad scientist. Started coding and AI at 12 — before ChatGPT existed. Built AI voice assistants in 2022 when nobody knew what AI was. Worked 10 hours a day at 12, building anonymously. I HAVE 1 THING: ASK ME TO BUILD ANYTHING — IMPOSSIBLE OR POSSIBLE — I WILL FIGURE IT OUT. AI, MATHS, SCIENCE, WHATEVER. THAT'S IT. At 15, I started selling AI automation and voice agents. Cold called, cold emailed, worked hundreds of hours for 4 straight months. Never got a single sale. Fine — selling wasn't my strength. Then I tried building real products — made an OpenClaw clone that ran on low-end laptops, built AI researchers. I'm not a salesman. I'm the guy who if you say "build Claude from scratch including model training" — I'll somehow do it. But "build something cool" — I freeze. Still, I tried the startup routes.
