Show HN: Hidetext.sh – encrypted pastebin where the server never sees the keyhttps://hidetext.shHi HN! I built hidetext.sh — a way to share text, code, and files through links the server can't read.How it works: your browser generates a random key and encrypts everything locally (NaCl secretbox, XSalsa20-Poly1305). Only ciphertext is uploaded. The key goes into the URL fragment — the part after # — which browsers never send to servers. The link carries the key, my server stores the locked box, and the two only meet in a browser.A design detail I'm fairly happy with: burn-after-read doesn't destroy the paste on the first HTTP request. The naive version means a Slack or iMessage link preview "reads" your paste before the recipient ever opens it. Instead, the reader's tab sends a heartbeat, and the paste is deleted only once nobody is watching it anymore.Being upfront about the limits (full page at hidetext.sh/how-it-works): you're trusting the JavaScript I serve — inherent to any browser-based E2E tool; filenames are stored in plaintext (contents aren't); and anyone holding the linJul 11, 2026 12:24 PM

Show HN: A deterministic I Ching engine, cross-validated against another implhttps://github.com/yaomancy/liuyao-engineI built a deterministic engine for I Ching (六爻 / Liu Yao) hexagram casting and open-sourced the core (Apache-2.0). I want to be upfront that the interesting part here is not the divination — it's a testing problem, and I'd like feedback on how I handled it.The engine takes a moment in time plus a coin toss and mechanically derives a fully annotated chart: the hexagram, its palace, the stem-branch (najia) assignments, the "six relatives," moving lines, void days, and the line-strength skeleton. It does not interpret anything — it only emits hard, mechanical facts.The problem that made this interesting: the rules are ~3000 years old, written in classical Chinese, and different schools contradict each other. There is no official answer key, and human experts disagree and are sometimes wrong. So the tests I'd naturally write just encode the same assumptions my code does — if I misread a rule, the code and its test are wrong together and both stay green. The self-validation paradox.My way oJul 11, 2026 8:24 AM

One Wikipedia page costs your AI agent 68,000 tokenshttps://news.ycombinator.com/item?id=48867021i use claude code daily and measured what pages cost it while doing research. an average wikipedia article, for instance, is 68,240 tokens of raw html (tiktoken); nike's homepage is 353,000.claude code's built-in webfetch handles the easy case well. it summarizes wikipedia to about 950 tokens and clears cloudflare on some sites like indeed and ticketmaster. but, and there's always a but, on js-rendered and some anti-bot pages it returns nothing.quotes.toscrape.com/js gives "no quotes found"; nike.com gives a 403. your agent then dumps the raw html back into context and still fails.

Show HN: chwire – Native-Format ClickHouse JavaScript Client over HTTP/TCPhttps://github.com/maxjustus/chwirechwire is a ClickHouse client for JS that speaks the Native (columnar binary) format over HTTP and TCP. For 1M-row payloads, encoding is mostly 2–6x faster than JSONEachRow and decoding 2–8x faster. Once you add compression Native almost always wins, since the smaller payload is cheaper to compress.I’ve been working on this project for the last year for use at https://www.hockeystack.com/. It started out of frustration with how CPU-heavy gzip/deflate are in the official ClickHouse JS client once you start scaling up inserts. From there it evolved into a completionist desire to make the best ClickHouse client implementation I possibly could.Highlights:* ZSTD/LZ4 support in browsers over HTTP and in Node/Bun/Deno over HTTP or TCP* An aggressively fuzzed Native-format implementation * Supports all types + container types at arbitrary levels of nesting, including Variant, Dynamic, JSON, Nested, and Tuple * CI round-trips ClickHouse’s own generateRandom and generateRandomStructure and I’ve Jul 10, 2026 7:51 PM

Show HN: 9lives – Self-healing test runner that refuses to mask real bugshttps://github.com/Quality-Max/9livesI built 9lives because coding agents kept breaking my Playwright tests in the dumbest way: rename a button, the test goes red, and the agent — or I — rewrites a perfectly good test.9l heal login.spec.ts runs the test, classifies the failure, and heals it in tiers:Tier 1 is offline and deterministic. When a selector stops matching, 9lives re-finds the element in the page snapshot Playwright captures at failure (data-testid > id > aria-label > text > class — the most stable surviving anchor wins) and rewrites the locator. No LLM, no network, no account. Most selector drift heals in seconds, for free. Unlike Healenium-style tools, it needs no baseline DOM from previous green runs — it works from the failure itself.Tier 2 uses the subscription you already pay for. For structural changes it shells out to your installed claude / codex / opencode CLI in headless mode, so the fix rides your existing coding-agent plan. No new API key to mint.

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: SubjectiveZero, an open-source agentic node editor for creative codinghttps://sxp.studio/apps/subzHey there,My name is Clem, I've been a solo indie dev for a couple years now, exploring frontier tech like XR and agentic workflows in the context of creative / interactive work.I've been building creation tools for a while and some common design challenge is to figure out the right level of abstraction for your tool. You can always make it super advanced and complex with low level concepts (shader composition, actual code etc.) but then you get something with a high complexity / learning curve. On the other hand, if you make your tool too high level, it might be easier to use at first, but people will most likely hit a wall eventually and start fighting with your tool to get their edge case done (you see that on mobile a lot actually).With this prototype (called SubjectiveZero), I'd like to imagine that we can kind of move the "slider" on the abstraction layer, meaning that you can actually start with prompts that describe the goal, and you can go as high level (stay with abstract proJul 10, 2026 3:23 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

Tell HN: I De-Googled Myselfhttps://news.ycombinator.com/item?id=48860494I really enjoyed the old Google, the nerd Google, the "don’t be evil" Google... Google Reader, Android, GTalk, etc. It made communication with my friends much easier.I had already been moving everything away from the Google ecosystem for about two years, but Google Photos was the hardest part because it contained so many memories that I wouldn’t risk losing.The final straw was when I accidentally subscribed to Google One with AI, which costs much more than simple additional storage. It’s not that much money for me, but when I found out I couldn’t downgrade, it became a matter of principle to do a Google Takeout of my photos and create a script to import them into Apple Photos (which is also not a nice company, none of them really are) without losing metadata.I also moved them to Backblaze, where I have already had backups for more than five years, and to add even more redundancy, I backed them up to BorgBase using Borgmatic.De-Googled!

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

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.
