Show HN: Minimal NIST/OWASP-compliant auth implementation for Cloudflare Workers https://ift.tt/s46VMG2

Show HN: Minimal NIST/OWASP-compliant auth implementation for Cloudflare Workers This is an educational reference implementation showing how to build reasonably secure, standards-compliant authentication from first principles on Cloudflare Workers. Stack: Hono, Turso (libSQL), PBKDF2-SHA384 + normalization + common-password checks, JWT access + refresh tokens with revocation support, HTTP-only SameSite cookies, device tracking. It's deliberately minimal — no OAuth, no passkeys, no magic links, no rate limiting — because the goal is clarity and audit…

Show HN: Algorithmically Finding the Longest Line of Sight on Earth https://ift.tt/zGJQbgS

Show HN: Algorithmically Finding the Longest Line of Sight on Earth We're Tom and Ryan and we teamed up to build an algorithm with Rust and SIMD to exhaustively search for the longest line of sight on the planet. We can confirm that a previously speculated view between Pik Dankova in Kyrgyzstan and the Hindu Kush in China is indeed the longest, at 530km. We go into all the details at https://alltheviews.world And there's an interactive map with over 1 billion longest lines, covering the whole world at https://map.alltheviews.world Just click on …

Show HN: ArkWatch – Uptime monitoring with zero dependencies https://ift.tt/pRkjJZ1

Show HN: ArkWatch – Uptime monitoring with zero dependencies I'm a solo dev, and I got tired of signing up for monitoring services that require installing agents, browser extensions, or wiring up Slack/PagerDuty just to know if my side project is down. So I built ArkWatch: a free uptime monitoring API with zero dependencies. No SDK, no npm package, no webhook setup. Just curl + your email. One command to start monitoring: curl -X POST https://ift.tt/qdFvDBH \ -H "Content-Type: application/json" \ -d '{"url":"https://your…

Show HN: Solnix – an early-stage experimental programming language https://ift.tt/h1zJ0Vn

Show HN: Solnix – an early-stage experimental programming language I’m building Solnix, an experimental programming language as a learning + research project. It’s still early, and many design decisions (syntax, types, tooling) are intentionally not fixed yet. My goal right now is feedback, not promotion: What design mistakes should I watch out for? What usually makes new languages hard to adopt? What would you avoid if you were starting today? Repo & docs: https://ift.tt/br517m9 I’d really appreciate honest criticism. Thanks for your time. https://…

Show HN: I Hacked My Family's Meal Planning with an App https://ift.tt/wiUx97u

Show HN: I Hacked My Family's Meal Planning with an App Me and my wife have been meal planning for the last 5 years. We used google keep. It was working for us, but during the years we needed to streamline the process. We tried other methods but nothing worked, so I spent the last 1 month hacking together this custom app. It includes all we needed to make our meal planning at least 5x more efficient. That is: syncing, one tap import of recipes, groceries, shopping mode, weekly meal plan, custom meals (like leftover, veg, eating out..) We managed to …

Show HN: Smooth CLI – Token-efficient browser for AI agents https://ift.tt/emxiHY0

Show HN: Smooth CLI – Token-efficient browser for AI agents Hi HN! Smooth CLI ( https://www.smooth.sh ) is a browser that agents like Claude Code can use to navigate the web reliably, quickly, and affordably. It lets agents specify tasks using natural language, hiding UI complexity, and allowing them to focus on higher-level intents to carry out complex web tasks. It can also use your IP address while running browsers in the cloud, which helps a lot with roadblocks like captchas ( https://ift.tt/cqskZrw ). Here’s a demo: https://www.youtube.com/watch?v=…
