Show HN: RunNburn – Run a 295B Moe from a 98GB GGUF on a 64GB RAM Desktophttps://github.com/coderredlab/runNburnrunNburn is an Apache-2.0 Rust inference engine for quantized GGUF models that are too big for your fast memory.The core idea: weights stay file-backed (mmap), host residency stays under an explicit byte budget (--ram-budget), and GPU caches are sized from detected free/total VRAM — never from device-name presets. There is no conversion step, no sidecar cache files, no silent requantization. The GGUF on disk is the single source of truth.The result that made me want to post this: Tencent's Hy3 (295B total / 21B active sparse MoE, a single 97.8 GiB Q2_K GGUF) runs on my desktop with 64 GB of RAM and one consumer NVIDIA GPU. The file is larger than RAM and VRAM combined; the selected experts for each token are pulled on demand (the newest path batches O_DIRECT reads through io_uring), while the pretrained routing is left untouched. On the same machine, same prompt, same decode length, a warm-run median gave ~5.5 tok/s decode vs ~2.0 tok/s for llama.cpp.To be upfront about scope: for modeJul 30, 2026 1:30 AM

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

Show HN: MandoCode Desktop – Native Windows AI Coding Assistant on Ollama .NEThttps://github.com/DevMando/MandoCode.DesktopQuick backstory on how this version came to be: the original MandoCode is a CLI, and its UI is built with RazorConsole — Blazor components rendered into a terminal. Genuinely clever tech! I wanted tabs, though, and when I attended MS Build this year I got a good look at what WinUI apps could do and saw the potential to give the original agent some actual windows and tabs. Having up to 4 agents running in one window is pretty cool. Aside from that — tabs! I feel like everything is a chat these days, and for some reason my brain keeps screaming AGENTS, not chats, at me. I love the tabbed-browser experience a lot moreSome of the stuff I got to toy with once the plumbing worked:- Context snapshots — closing an agent archives the conversation instead of deleting it, and you can snapshot mid-conversation to get an AI-written recap you can hand to a different model or a fresh agent and have it pick up the thread. You pick the LLM from a dropdown right when you create the snapshot.- TranscriptJul 29, 2026 4:48 PM

Show HN: Vostorq – I built the anti-Slack after working at a Slack-first companyhttps://www.vostorq.com/A while back, I joined a company with a "Slack-first" communication policy. I was concerned from the beginning because Slack or Teams had never felt sufficient at the companies where I'd worked before. Some discussions happened over email, meetings played an important role, Jira was used heavily, and Google Docs or Confluence was used for documentation. That setup felt necessary, but it wasn't optimal. So the "Slack-first" approach sounded suspicious, but intriguing. I was curious what they had done with Slack to solve this multi-tool mess. In practice, though, it didn't solve it for me.Take the DevOps support channel. I was new, the infrastructure setup had some issues, and I asked question after question, feeling more and more like an idiot who constantly bothers people (potentially, every person in the channel), because sometimes it was a genuine bug, and sometimes it was simply my misunderstanding of the setup. I always got answers eventually, but they were slower and shallower thaJul 29, 2026 2:45 PM

Show HN: LLM-spend – Audit your OpenAI/Anthropic API spend locallyhttps://github.com/kliukovkin/llm-spendI build spend-pacing systems for ad auctions for a living, and my side-project agent workloads still kept surprising me with API bills I couldn't explain. When I asked around how people attribute LLM spend, the answers were the provider dashboard or a spreadsheet.llm-spend is a local CLI that pulls usage from the OpenAI/Anthropic reporting APIs, breaks spend down by key, model and project, projects end-of-month, and flags days that look abnormal against the same weekday's history. It also does a second, independent read of the provider's cost API and warns if the totals disagree by more than 1%. That check exists because I don't want to ship you a wrong report: it catches unit, pagination and grouping bugs in my own pipeline. It checks against the provider's cost API, not your invoice — credits, tax and non-API charges live elsewhere.Keys are the ugly part. OpenAI admin keys can be scoped down to read-only usage/cost access, but admin keys require a Team plan. Anthropic admin keys can'Jul 26, 2026 4:20 PM

Show HN: Brolly, a plain-text weather forecast sitehttps://brolly.sh/forecast/RWFP2qW8The UK MET office recently redesigned their site, adding a lot of additional whitespace, scrolling, and animations. This significantly reduced its usability for me, and left me wanting an ‘at a glance’ weather site.I made https://brolly.sh, a minimalist, plain text weather forecasting site. You can use it to view weather from around the world, with: 7 day forecast; Previous day log (so you can confirm it definitely was cooler / hotter / wetter / drier yesterday!); Hourly rain, wind, temperature, conditions; Hourly UV, air quality and pollen, including pollen type specific forecasts within the EU / UK; Location search and last 5 locations; Location specific units.I mostly made the site for myself, if anyone else also benefits from it that’s an added advantage.You can check out the weather in York, UK at https://brolly.sh/forecast/RWFP2qW8, or search for a location at https://brolly.shThe site is deliberately styled as a single long scrollable column, to work on mobile phones.

The Cost of Seamlessnesshttps://news.ycombinator.com/item?id=49048352The Hidden Cost of Frictionless Technology Taotuner — 2026I recently asked an AI assistant for restaurant recommendations. It listed five places, complete with ratings, distance, and popular dishes. I picked one, went, had a fine meal. Later, when a friend asked what I'd eaten, I couldn't remember the name of the restaurant.The experience wasn't bad. It was frictionless. And it left almost no trace.We've built tools that eliminate the gap between want and satisfaction, question and answer, curiosity and resolution. We call it seamlessness. We've assumed it's progress. But the gap wasn't inefficiency — it was where memory, judgment, and understanding used to form.What if removing it is making us less capable?The Pattern This isn't just about restaurant recommendations. The same dynamic shows up across AI, therapy, cities, and education.Take AI assistants. The industry evaluates them on speed, accuracy, and satisfaction. Those metrics capture whether the tool works.

Ask HN: Multi dimensional sort (beyond Hilbert curve)https://news.ycombinator.com/item?id=49042861My point is about structuring and indexing an arbitrary dataset, for preprocessing before eg segmentation/clustering, neighbor querys...In 1D, sorting is trivial because scalar values have a total, unambiguous order. In 2D and higher dimensions, there is no single way to order points, and points can't all be compared >=/=_k v if u_k >= v_k (comparing along the k-th coordinate axis only).In 1D, a sorted array satisfies x[i+1] >= x[i]. Extending this naturally to a multi-indexed d-dimensional array x[i, j, k, ...], we can define a dataset as "cartesian sorted" if:- x[i+1, j, k, ...] >=_1 x[i, j, k, ...] - x[i, j+1, k, ...] >=_2 x[i, j, k, ...] - ...and so on.In other words, the array of multi indexes is sorted along every row, column, and slice under its corresponding coordinate projection.What makes this definition interesting is that their exist a very simple algorithm to perform Nd sort in the "cartesian" sense. Just iterate: 1. Perform 1D sorts along every row (apply the permutation Jul 24, 2026 11:27 PM

Show HN: Build native iOS widgets from any HTTPS endpointhttps://news.ycombinator.com/item?id=49033628I built Dashlet since I often found myself building different web dashboards for all sorts of data (custom page views monitoring, app downloads, info from my home sensors) and I quickly got tired of always having to navigate to a page in Safari and reenter credentials to access them.I wanted to just simply be able to see it on my phone, when scrolling around it - in almost realtime.I've built bespoke apps (just for myself) in the past, that mapped a specific custom API for that purpose, but it was a hassle anytime I changed something in the response or added some new API for myself.So, Dashlet is an answer to that - it can handle any JSON (or XML, or even image) endpoints and has a nice interactive way of picking which values out of it should be displayed in which type of widget. So, if something has an API but no app (or no widget), Dashlet lets you point it at an HTTPS endpoint, visually map fields from JSON/XML/images, and create native Home Screen (also lock screen and Apple Watch)Jul 24, 2026 10:41 AM
