[Other] Show HN: Cdecl-dump - represent C declarations visually A small tool that parses C declarations and outputs a simple visual representation at each stage, as it encounters arrays, pointers or functions.<p>The program uses a table-driven lexer and a hand-written, shift-reduce parser. No external dependencies apart from the standard library.

[DevOps] Show HN: Minimal container-like sandbox built from scratch in C Runbox recreates core container features without relying on existing runtimes or external libraries. It uses namespaces, cgroups v2, and seccomp to create an isolated process environment, with a simple shell for interaction. For future gonna work on adding an interface so external applications can be executed inside Runbox, similar to containers.<p>Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;Sahilb315&#x2F;runbox" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Sahilb315&#x2F;runbox</a><p>Happy to hear feedback or suggestions.

[Other] OpenTelemetry Distribution Builder

[CLI Tool] Show HN: Tascli, a command line based (human) task and record manager `cargo install tascli`<p>Manages your own task and records in the terminal simply with tascli - tiny, fast and simple.

[CLI Tool] Show HN: TapeHead – A CLI tool for stateful random access of file streams I wrote this tool while debugging a driver because I couldn&#x27;t find a tool that allowed me to open a file, seek randomly, and read and write.<p>I thought it might one day be useful to someone too.

[Other] Show HN: I designed my own 3D printer motherboard 3D printing is such a fascinating field of technology, so a couple months ago, I decided to take a deep dive and learn how they actually work!<p>This took me to one of my very first PCB projects, a small, cheap, 3D printer motherboard. While it&#x27;s not the most cutting edge board, I learned a lot and I fully documented my process designing it (<a href="https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini&#x2F;blob&#x2F;master&#x2F;JOURNAL.md" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini&#x2F;blob&#x2F;master&#x2F;J...</a>), so other people can learn from my mistakes!<p>It runs off of an STM32H743 MCU, has 4 TMC stepsticks with UART&#x2F;SPI configurations, sensorless&#x2F;endstop homing, thermistor and fan ports, parallel, serial and TFT display connectors, bed and heater outputs and USB-C&#x2F;SD Card printing, all in a small 80x90mm form factor with support for Marlin and Klipper!<p>Because it&#x27;s smaller and cheaper than a typical motherboard, you can use it for smaller&#x2F;more affordable printers, and other people can also reference the journal if they&#x27;re making their own board!<p>If I were to make a V2, I would probably clean up the traces&#x2F;layout of the PCB, pay more attention to trace size, stitching and fills, BOM optimize even further, and add another motor driver or two to the board. I also should&#x27;ve payed a bit more attention to how much current I would be drawing, and also the voltage ratings, because some of the parts are under-rated for the power.<p>I&#x27;m still actively refining it and fixing up some of the mistakes, but I plan on using this board to make a tiny foldup 3D printer I can bring to hackathons and 3D print on the go!<p>The project is fully open source, and journaled, so if you&#x27;d like to check it out it&#x27;s on GitHub (<a href="https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini</a>)!<p>I absolutely loved making this project and I&#x27;d love to hear what you guys would want to see in a V2!

[Other] Build like it's 2084 I'm excited to introduce GlitchCN, a retro futuristic React component library that brings terminal styled aesthetics to Next.js applications. Modern UI libraries have converged on clean, minimal designs. While these work well universally, developers building portfolios, tech dashboards, or products needing distinctive visual identity lack alternatives. GlitchCN solves this. Visit glitchcn-ui.vercel.app for demos, documentation, and code examples, because the web deserves more personality!

[API/SDK] Automated data anonymization platform Today we’re launching Sanitidata, a lightweight API + SDK that helps developers anonymize sensitive data the right way — before it touches your logs, analytics, or third-party services. If you’re handling emails, phone numbers, IPs, addresses, or customer records, you must anonymize them to stay compliant with GDPR/CCPA and to protect your users. But most dev teams end up using fragile regex hacks or half-baked masking logic. Sanitidata fixes that.
