Show HN: Reading Pacer – A "Struggle Detector" for kids learning to readhttps://readingpacer.com/Hey all,Oral Reading Fluency is incredibly important for burgeoning readers. It needs to be measured tracked, and if needed, used to justify reading interventions.Currently, teachers do this the old fashioned way, 1-on-1 teacher to student with a "levelled" reading passage (false precision) and a stopwatch. The accuracy is only as good as the teacher's skill and training.Historically, Automatic Speech Recognition software has been hamstrung by being overly-strict, not understanding children's inflection and pitch, and generally being impersonal.I tried to address this by building my tool which I call Reading Pacer, which allows any parent or teacher to use any physical book (or from our digital library) to quickly and easily run regular, long, or specialized ORF assessments on their own.All the feedback I have received has been positive, but online marketing is not my strong suit. I would like to submit my website for feedback but I think that might be against the sub rules(?)Thank you

Show HN: I rebuilt my 2008 soccer/lineup sitehttps://news.ycombinator.com/item?id=49127360I originally built fantastic11.com in 2008. The browser-based lineup editor alone took me several months to build. Here’s an old demo video from that time: https://www.youtube.com/watch?v=27_Bx4Z8nbE / https://www.youtube.com/watch?v=aU_DBT8mOXU Over the years, I added a few smaller features, but as a father of three, I rarely had much time left for this side project. This week, I rebuilt the entire site in just a few days using Codex and a $20 subscription. What surprised me wasn’t only the speed. The new version ended up being much more complete than the original. The workflow still feels strange: I describe what I want, spend some time with my children or take care of things around the house, then come back to find much of the implementation ready to review. It’s a very different way of building software, and I’m still getting used to it. You can try the new version here: https://fantastic11.comI’d be happy to hear your feedback—on the site itself or on similar experiences rebuildin

Show HN: Usbatlas – simple CLI utility to see what USBIP devices are attachedhttps://github.com/comalice/usbatlasHello HN,This is a simple CLI that I vibe coded to scratch an itch at work.The problem we had was multiple USBIP devices attached to a single Linux server, and we were having a hard time seeing who connected what.Enter `usbatlas`. It's a basic app that lives on top of the Linux device file system and depends on `usbip` [0][1]. It allows you to see what USB devices are attached to your Linux box and where they come from. Currently the device source IP resolution has some issues. I'm working out the kinks right now.Here's an example output: $ usbatlas --usbip xHCI Host Controller [serial: xxxx:xx:xx.x] +- USB2744 +- Lenovo New Calliope USB Keyboard +- /dev/hidraw0 +- /dev/hidraw1 +- /dev/input/event3 +- /dev/input/event4 +- /dev/input/js0 +- Lenovo USB Optical Mouse +- /dev/hidraw2 +- /dev/input/event5 +- /dev/input/mouse0 +- Bluetooth 9460/9560 Jefferson Peak (JfP) +- USB2.1 Hub +- USB2.1 Hub +- Saleae Logic +- FT4232H MiniModule [serial: xxxxxxxx] +- /dev/ttyUSB4 +- /dev/ttyUSB6 +- /de

Show HN: Schema-backed, Git-based structured state for agentic systemshttps://news.ycombinator.com/item?id=49126792I looked into how to store agentic state in a) a structured way that b) runs without any dedicated MCP memory/state servers and where I can get c) a clear diff-able audit trail of all state changes over time. Nothing that I could find fit the bill.In https://github.com/commitspark/demo-agentic-mcp , I demo an implementation that fulfills these requirements by combining Claude agents with my previously published Commitspark library and its entirely Git-backed GraphQL API.In the demo, two independent Claude agents are simulated that contribute to a task tracker. A third agent reviews any task changes and rolls back obviously bad ones. A full demo transcript is included in the README, including the agents' raw tool calls.Task agent access to data happens via a small MCP server that exposes two Commitspark APIs (GraphQL API, schema API). These agents can then fetch the schema and author their own GraphQL calls, with GraphQL automatically enforcing written data is schema-conformant. The val

Show HN: The Goal is simple, there should be an actual free editorhttps://sylixide.comHey HN, I'm Saai, one of the creators of Sylix. I made this open-minded version of Cursor where you can get all of the core features of Cursor but in a fully customizable IDE (Ctrl+K, @docs, parallel agents). We love Cursor so much, but there are so many other features we're building, including all things like multi-edit, parallel swaps, agent indexing (but not the traditional one), parallel LSP, or maybe... we might give agents a better understanding of the codebase via multi-semantic memory instead, alongside in-search grep for your system files or workspace. Sylix will be open source once it's stable, but it's a fully customizable tool we've been wanting!Sorry for the delay; well, it's almost a year now. Well, I know developers were waiting for this.The hard part: we're building Sylix not as a traditional fork of VS Code but as a mixer of all things; Sylix is built on top of Monaco Editor along with the Monaco Editor API, backed natively in Rust. The VS Code repo helps a lot, along

Show HN: How I built Remembered checkout for Voicehttps://ringup.dev/If you ever built a voice agent that takes orders or books appointments you know its essential to collect payments to avoid cancellations/no-shows. However, most consumers won't complete paying because of the friction involved (stumbling for the card, speaking the card number CVV etc).I built Ringup to help voice agents recognize repeat callers with just their phone number and charge their saved card in seconds.I've been asked what makes this lookup possible. Its the newly launched identity APIs from US carriers (T-Mobile, ATT, Verizon) as part of CAMARA project. These set of open source APIs now make it easy for developers to reliably verify identity directly from carriers and is much more robust than sending SMS OTP.If you're a Voice AI developer or know someone who is, I am offering free credits for 5 users in exchange for any feedback. Try it out.

The Mistake That Cost Me a Yearhttps://news.ycombinator.com/item?id=49124280last year i was randomly visiting a website and couldnt download a video in hd quality. as a dev, when smoething doesnt work, you think "let's build it." so i started researching and found like 0.2% of these sites actually worked, but full of shitty ads. checked their traffic and got shokced, tens of millions of visits.started building with a regular MEAN stack. i was 17, knew how to code but wasnt experienced, just pushed by those traffic numbers. used yt-dlp as the core scraper along with other fallbacks like youtube-dl and unofficial tiktok apis. by all means i was overengineering, tryign to build a bulletproof system with fallback on fallback. took two months, and by the end changing one line meant touching 15 to 20 files. that's bad code.rewrote it, stripped external deps, used yt-dlp efficiently in node js. still slow, 10 to 15 sec just to fetch info, another 10 to 15 to start download. tried optimizing args and prewarmed pools, still stuck around 9 to 10 sec. obsessed with speed

Show HN: I built a cross-browser extension that controls fingerprinting surfaceshttps://privacything.com/en/Hello Hacker News! I’m Tomasz, creator of Privacy Thing, a browser extension for Firefox and Chromium-based browsers. I’ve just released its Preview version.Privacy Thing aims to reduce browser fingerprinting—the tracking of users without cookies.It began as an internal project: a simple location simulator. Over time, I expanded it to cover more fingerprinting surfaces. It now has 13 protection categories affecting 50+ browser APIs and methods: Geolocation, time and locale settings, Canvas, WebGL, Audio, Navigator, Screen, Client Hints, Battery, WebRTC, Dedicated Workers, Service Workers, and Shared Workers. The list is still growing.The extension is fully configurable. Users can create regional profiles and assign them to domain rules, with separate protection settings for each domain. Or they can skip domain rules and rely on the global configuration—I’m not here to decide what works best for them :-)Privacy Thing uses Manifest V3, with all its pros and cons.

Page up / Page Down are next or previous level (if already unlocked).Cheats: Z toggles zapper, M toggles magnets.Debug stuff: I, P, E keys are toggles for various stuff (E lets you change some aspects of physics engine).Game is maybe playable on mobile devices, there is a menu on top right, and then click the circle to select type of control.Physical engine is decoupled from refresh rate and runs at 240 Hz.Fully vibe coded (deepseek, chatgpt), levels are human made with some amount of love.

It runs on any Unix-like operating system up to 25 years old and will almost certainly build and run everywhere in another 25 years without any need for updates.

Show HN: Yet Another Markup Language Engineering Toolkithttps://github.com/RicardoMonteiroSimoes/YamletOver the past few weeks I've grown tired of these super, all in one, agentic AI Skill plugins, MCP servers and whatnot that promise you the world. Of course, there is a world of vibes that survives off that, but there is also a world of more constraints and responsibilities.Hence I built Yamlet: A CLI tool with accompanying Claude Code skillset, that merges both deterministic checks with human like interface to help you define requirements - including acceptance criteria, which are then promptly used to generate adequate Gherking .feature test files. The details are stored in a minimized fashion as .yamlet.yaml files, which allow quick and easy review - without the usual multi page slop specs.- And that's it. Everything else, depends entirely on the system you're working on. I stopped here because for me, this can not only be used in a system of pure agentic coding, but also with a normal dev team.

Tell HN: Gemini uses your email drafts (if you have "smart features" turned on)https://news.ycombinator.com/item?id=49123174If you use Gmail, I think you all should know that if you turn your "smart features" on (a setting in gmail), the contents of your email drafts will make it into public-facing AI-generated content you generate. (I did have a chance to review it).It was surprising behavior to me that's worth keeping in mind.Detailed story:I usually keep "Smart features" turned off in Gmail, however, I was using Google Gemini and file upload didn't work. I therefore shared from my Google drive, which required turning on "Smart features" in my gmail, so I did so.Later, I was reading this announcement about a Google robot on Hacker News on my phone:https://news.ycombinator.com/item?id=49111237I started typing out a response on Hacker News but decided to make it a higher-quality comment so I saved my draft in gmail, and sent a second email to myself.
