[Other] Show HN: Wsgrok – one of many ngrok alternatives I built it for myself because ngrok didn&#x27;t let me add one more domain unless I paid $12 more. I probably should&#x27;ve looked for alternatives before building my own, but my grudge got in the way . Once I started, I wanted to make it better than the other options. Silly, I know. No one probably cares.<p>I plan to open source it sometime next year because I’ve got other projects to finish first. It&#x27;s free until I deplete my cloud credits, then it will switch to a tier-based model with a free option.

[CLI Tool] Show HN: The System Skill Pattern Hello HN!<p>I’ve been playing with Claude Skills and stumbled on a simple pattern for tiny, durable personal data systems:<p>* CLI: a small, self-contained executable<p>* SKILL.md: the operator guide (what to run, how to parse output, how to think about the system)<p>* SQLite: a local DB for persistent state<p>It’s nothing mind-blowing, but the ergonomics of this combo feel great.<p>If you define a process&#x2F;flow, Claude can &quot;turn the crank&quot; by running the CLI, accumulating context, and animating the system to life over time.<p>They’re also easy to share: you can distribute System Skills via Claude Code’s `&#x2F;plugin marketplace add &lt;repo&gt;`.<p>More details in the blog post and the toy Pomodoro System Skill reference implementation here:<p>Blog: <a href="https:&#x2F;&#x2F;www.shruggingface.com&#x2F;blog&#x2F;the-system-skill-pattern" rel="nofollow">https:&#x2F;&#x2F;www.shruggingface.com&#x2F;blog&#x2F;the-system-skill-pattern</a><p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;jakedahn&#x2F;pomodoro" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jakedahn&#x2F;pomodoro</a><p>--<p>Curious whether any of this resonates. Also excited to hear any interesting System Skill ideas worth exploring!

[Other] Show HN: I built an 8-bit CPU simulator in Python from scratch I built a tiny 8-bit CPU simulator in Python to better understand how computers work at a low level. It visualizes registers, memory, and instructions in real-time, so you can actually see each operation as it happens. You can write simple assembly code and watch how the CPU executes it step by step.<p>The project is mainly for learning and experimentation, but I’d love feedback or ideas for improvement.

[Other] Show HN: A fast, privacy-first image converter that runs in browser Hey HN<p>I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions.<p>So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy.<p>What it does<p>Convert images between JPG, PNG, WebP<p>Works offline once loaded (PWA support)<p>How it works<p>It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices.<p>Why I built it<p>I wanted an instant, no-ads, privacy-safe way to handle images for my personal projects — something lightweight enough to replace desktop tools.<p>Try it<p><a href="https:&#x2F;&#x2F;imageconverter.dev" rel="nofollow">https:&#x2F;&#x2F;imageconverter.dev</a><p>Would love feedback from the community — especially on:<p>Performance on different browsers&#x2F;devices<p>Thanks for reading!
