Show HN: Reinhardt – Django-style Rust framework; WASM+SSR from one DSLhttps://github.com/kent8192/reinhardt-webReinhardt is a Rust web framework where one component DSL compiles to both WASM (client) and server-rendered HTML — a single file describes both sides of a page, with no separate frontend codebase, no JS build toolchain, and no duplicated types across the client/server boundary.It also bundles what Django/DRF users expect: an ORM with auto-generated migrations from #[model] macros, DI, auth, admin, REST, background tasks, and i18n. Feature flags let you pull in just what you need (minimal / standard / full), or import individual crates directly.I built it after moving from Django/DRF to Rust and repeatedly re-assembling the same Axum + ORM + migrations + auth stack for every project.Quickstart: https://reinhardt-web.dev/quickstart/v0.1.0-rc.18 release: Crates.io (published as reinhardt-web; the shorter name was taken): https://crates.io/crates/reinhardt-webBSD 3-Clause.Apr 22, 2026 1:00 PM

Show HN: Notation – an iOS chess coach (Stockfish on device and optional BYOK)https://notationchesscoach.appHi HN. Solo iOS middle aged, slightly burnt out dad from the UK here, wondering if anyone is interested in what I've been building. Lifelong chess fan, not very good but always trying to improve and I started to build Notation: Chess coach a while back. It's been live a month now on the App Store, doing modest numbers, and I've been learning a lot... mainly make my add brain slow down, stop, test everything twice and never when tired. Submissions will always wait another day!Many people play on chess com, or lichess, just as many in apps and OTB. What my app does (differently I hope) is bring that data together.You can import PGNs of your games, connect to chess com and lichess and sync your games over or play in the app. If you have a Chessnut electronic board, you can play IRL on that as well.Every game, every move is then analysed by a series of on device detectors, and classifiers. And I'm not talking about"I run Stockfish 18 and get your move evals" like most tools do.... Theres aApr 22, 2026 7:46 AM

Instead of writing my manuscript, I built a toolhttps://news.ycombinator.com/item?id=47849297Hi my name is Jeff, and I am a chronic procrastinator when it comes to my writing…Tell me that doesn’t sound familiar, I’ve literally written two blogs about this instead of actually writing my manuscript, cause literally anything (even scrubbing the toilet) is more compelling than the grind of getting through chapter 6.I actually started writing a tool in early January 2025. At the time, I was trying to find a way to gamify my writing. I wasn’t really looking to launch a serious writing tool at the time, just find a way to hack my brain into doing the work (and find another excuse to not write).The result of that was a simple text box with a word counter (0/500 words) that used a little bit of JavaScript to count the words you dumped in the box, deduct any shorter than 3 letters and then let you know if you hit your writing goal for the day (and you even got some fireworks!)The tool worked, I found myself anticipating pasting my daily writing progress into the box for that dopamine reApr 21, 2026 2:25 PM

Ask HN: Would you use revocable digital signatures to verify AI/Other content?https://news.ycombinator.com/item?id=47848539I’ve been exploring a potential product direction and wanted to sanity check it with people who actually build and ship things.Background: I’ve been working on a system using our core tech that can generate and verify digital signatures, but with a slightly different property than traditional approaches. The signatures are natively revocable. If the underlying model/system shouldn’t be trusted anymore, the signatures can be revoked either through a hard (delete the signing model) or soft (revoke the lease for the signing model) mechanism. I believe this feature is very beneficial on its own, but there are several other interesting properties (no key management, distributed verification, embedded metadata, etc.)Originally this came out of some deeper R&D work we’re doing, but I’ve been thinking this might actually be the most practical “wedge” into the market while we continue that research (and fund the research).One area that’s been interesting is applying this to AI systems.

Hubble turns 36 with a dazzling Trifid Nebula portraithttps://www.esa.int/Science_Exploration/Space_Science/Hubble_turns_36_with_a_dazzling_Trifid_Nebula_portraitThe NASA/ESA Hubble Space Telescope looked at a scene it first captured in 1997 in honour of 36th anniversary: a small portion of a star-forming region about 5000 light-years away in the constellation Sagittarius, known as the Trifid Nebula. The image shows changes over incredibly short timescales and instills a sense of awe and wonder about our ever-changing Universe.Apr 20, 2026 2:00 PM

Observability Stack – AI First?https://news.ycombinator.com/item?id=47819461So... I'm way behind. Just got into Claude this week... it's already doing most of my coding and bug fixes. Crazy stuff.Some background on my company: Mature (14 yrs) Ruby on Rails app, Sidekiq, Redis, PG, AWS lambda/eventbridge, react/preact, swift, and others. Hosted on Heroku. Very database heavy. Solo guy, owner/operator.Current stack:Datadog logging (dabbled in APM, metrics, and others, but the build pack for Heroku is so bloated I had to remove it), so now it's a simple Heroku log drain to datadog. I really miss the statsd host and APM stuff... but it took my slug size from ~250mb to over 350 and made booting and deploys much slower. I'd also like to get off Heroku.... some day... but I can't event fathom it.Bugsnag for errors. Already moved this to Sentry to try out the AI stuff.A little fed up with Datadog and receiving $600 monthly bills on top of my enterprise commitment. biggest pain points: indexing is priced per line, not by gb (discourages me from simple logging, so I resApr 18, 2026 8:55 PM

Ask HN: Does magic link authentication use HTML canvassing?https://news.ycombinator.com/item?id=47817835Many sites are starting to use magic link auth more often and I am wondering if its a trend to also glean more information from the account holder.I dont like this auth process because it forces me to have to use the email system to authenticate every time which adds to the amount of time it takes to log-in. With Claude.ai, the auth process at least gives you an option to use a code to sign in with after you get the email. The problem is, the email doesn't contain the code. You have to click on a link which opens a web page to gain the code and it appears at that point it wants to do an HTML canvassing operation. I feel like that is a violation of privacy to do this at the point of trying to log into a service I pay for. I'm wondering if I am off base or if anyone notices this, or finds a difference in the process. and if its happening, what can be done about it. Also I wonder what the real reason is why more and more companies are moving toward this authentication method.Apr 18, 2026 5:40 PM
