How NASA Uses Light to Detect Waste From Mineshttps://science.nasa.gov/earth/how-nasa-uses-light-to-detect-waste-from-mines/Tens of thousands of abandoned mines threaten waterways across the American West, but identifying which sites urgently need cleanup is slow and expensive. Now, NASA’s EMIT instrument can analyze the unique light signatures of mine waste from space to help focus remediation efforts where they’re needed most.May 28, 2026 2:20 PM

Show HN: Monochess – A chess variant with rule-bending action cardshttps://monochess.pages.devHey HN,A while back I saw a video[0] of people playing chess but using action cards to modify the rules mid-game (skip turns, reverse, draw 2, etc.). It looked incredibly chaotic and really fun to play, so I decided to actually build it as a playable online game. A small difference in Monochess is there's no need to call out a phrase if you just have one piece. I noticed while testing with the mrs. it became really annoying to keep doing this every move.That also gave me a really good reason to build on Cloudflare using their entire stack, something I've been meaning to get my hands dirty with for quite some time. The app is built using SvelteKit and hosted on Pages, there's a Durable Object worker-backed game server, and D1 as the database layer for accounts/games.This project included:- A Custom Engine: Standard chess engines panic when forced into illegal board states. The engine wraps standard chess logic to allow for mid-turn state changes—handling concepts like rolling back a comMay 28, 2026 1:58 PM

Show HN: I made samspov.com to easily track updateshttps://samspov.comI've discovered this TikTokker called samspov a few months ago, and was immediately taken aback by the way he handled himself and tried to shine a spotlight on restaurants that were struggling but didn't have to be (great food, no audience).He tries to do updates and the bigger his fame got, the more incredibly the change for the restaurants.While TikTok is great for consuming lots of content, it's not great for context, so I made something that pulls in the videos, tries to figure out which restaurant it is, query Google Places API (paid but luckily, I think they have a fairly generous threshold before it charges ), and this way, tries to tie everything together, which lets me link videos to a restaurant, give them a page that gathers the videos there, so you can watch the orignal visit + any updates, but also gives links to their website, menu, phone number, opening hours, etc.Sometimes Sam does fundraisers for restaurants that are really struggling; I try to link active fundraisers May 28, 2026 8:07 AM

Dirty Frag: a kernel zero-day vs. container and microVM sandboxeshttps://news.ycombinator.com/item?id=48304227On May 7, Hyunwoo Kim (V4bel) disclosed Dirty Frag — two Linux kernel vulnerabilities (CVE-2026-43284 and CVE-2026-43500) that give unprivileged users deterministic root on most Linux distributions shipped since 2017. Microsoft confirmed active exploitation the next day.We build declaw.ai — sandboxing infrastructure for AI agents, on Firecracker microVMs. We run untrusted code we don't write and can't predict, so when Dirty Frag dropped our first question was: does our isolation boundary hold? We tested it on a deliberately unpatched kernel. It held. Here's why.The exploit is a page-cache write primitive: it tricks the kernel into overwriting the in-memory contents of any file (/usr/bin/su, /etc/passwd) and gives root. Fully deterministic, no race.Why it matters for multi-tenant platforms: the page cache is shared across the whole machine. Containers share the host kernel, and namespace isolation, seccomp, and dropped capabilities are all enforced by that kernel. A kernel exploit doesnMay 28, 2026 3:43 AM

Show HN: Hm – a task runner with a Python DSL, growing into a CI/CD systemhttps://github.com/harmont-dev/harmont-cliHi HN! My name is Marko and I am working on a CI/CD system at harmont.dev, a CI/CD system that sucks slightly less. As I've been working on the cloud, I realized that the CLI might be generally useful as a task runner, even if you don't care for our CI/CD, and that's what I'm sharing here!Every CI system I've used at Tesla, Bun, and mesa.dev has had the same problems: stateless and slow (GHA), or stateful and horizontally unscalable (Jenkins), with YAML on top of either. The straw that broke the camel's back for me was the realization that all my Claudes are waiting upwards of an hour. So I quit my job to work on harmont, which aims to solve all of these pain points I've had.In its current state, the project is very similar to Dagger in spirit with the core difference of harmont having what I believe to be a more pleasant API as well as being smaller in scope.I'm looking for opinions and feedback. What might be the most interesting with the CLI is the DSL -- I've tried to make it ergonMay 27, 2026 4:41 PM

Show HN: I hand-write 5 daily word puzzles before workhttps://www.dailyworder.com/I build and hand-write five daily word puzzles at dailyworder.com. Every clue and answer for the dailies are mine — I use AI for the code and it's unlocked crazy speed on small but thorny problems.One technical detail as an example: Pyramid's editor (one of the five games) uses a ~350KB precomputed dataset of valid frameworks — grids where a single vowel, dropped into every slot, produces valid English words across all rows. Building the dataset was the actual work (combinatorial search over a 60k-word dictionary with constraint checks) but I did that in one session. Runtime is trivial: pick a framework, pick a vowel, render. Works offline. Don't think I could spend the time on it before LLMs.The other four:- Fourbe — Connections-style, but the connections are spelled out in crossword-style clues across four rounds- Spying Bee — Word find flipped on it's head where players must reveal letters before they can select- Invertle — word guesser with higher/lower hints- Totum — letter-tile sMay 27, 2026 10:30 AM

How to prevent ideological capture of sites like Wikipedia, HNhttps://news.ycombinator.com/item?id=48290346Someone submitted a link [1] to an article on Wikipedia's whitewashing of Mao titled Wikipedia Whitewashes Mao – The Anatomy of Ideological Capture [2], a topic which in a more generalized form is of interest to the current average HN denizen given the prevalence of Wikipedia in LLM training data. It did not take long for the flaggers and down-voters to take down the article which has only managed to get a few comments, the top one claiming the article to be 'a pretty political take on a Wikipedia article'. I think the subject deserves more discussion since it points out a clear problem with sources like Wikipedia but also because of the way this article was quickly flagged to death. The flagging and down-voting mechanisms make sites like HN vulnerable to the same type of ideological capture as what is discussed in the linked article in that a relatively small group of motivated users can suppress 'unwanted' subjects while boosting those which fit some desired narrative.[1] https://newMay 27, 2026 6:14 AM

Show HN: STAX IDE – A zoomable macOS canvas of terminals and toolshttps://staxide.comHi HN. STAX IDE is a macOS app where every terminal session, code editor, and file browser is a movable, resizable window on a single zoomable canvas. `Cmd+wheel` to zoom out and see the whole workspace; zoom in to one window and use it like a normal app.I built it because I was running 8-10 Claude Code / Codex shells in parallel and tabbed terminal apps kept losing my place. I wanted to see every shell at once and drag them around like Post-its. And have my browsers and notes in there too.Implementation choices that might be interesting:• AppKit, not SwiftUI. I needed manual frame control during drag/zoom to avoid AppKit's display-cycle re-entrancy guard, and got it more reliably out of straight NSView land.• SwiftTerm (Miguel de Icaza's emulator) for VT100 + real PTYs (fork + openpty). One `LocalProcessTerminalView` per tab. OSC 7 → cwd → tab title.• `NSScrollView.magnification` for canvas zoom. Cmd+wheel events are coalesced to one mag-update per display frame and the resync broadcaMay 27, 2026 4:39 AM
