[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!

[Other] Show HN: Inspec – Specification scheduling software for interior designers Hi HN, I&#x27;m Nick and I built Inspec with my partner Caitlin (she&#x27;s the interior designer, I&#x27;m the developer).<p>Inspec lets interior designers create and manage FF&amp;E schedules - basically spec sheets listing everything that goes in a room before the furniture: flooring, paint, countertops, lighting, fixtures, etc.<p>This process is currently exclusively done using Excel, and while this works to some degree, it comes with a lot of manual work and clunkiness. When Caitlin started working remotely, I watched her deal with these issues daily. So I spent the past 9 months building a better solution.<p>Key Features:<p>- Realtime collaboration<p>- Revision control (versioning)<p>- Professional PDF exports<p>- QR codes to print out on-site for contractors, builders etc. to always have the latest version<p>- Completely customisable fields and a familiar workflow to Excel to keep learning curve small<p>When we first started building this we thought it was completely unique, but turns out there are 2 competitors. I think our positioning is quite different though as we seek to only replace this document creation, rather than overhaul the entire project management and try to be a complete solution. So that’s helped to guide our focus, but also validated that interior designers are looking to modernise their software.<p>Tech stack:<p>I used my SaaS boilerplate which is just a modified T3 stack template with everything set up just how I like it. So Next.js with the pages router, TS, Trpc, Prisma + PostgreSQL, and TailwindCSS. I’ve also got Pusher for realtime collaboration, Redis and BullMQ for keeping a seperate background worker for PDF and web scraping jobs.<p>I can’t imagine many interior designers are on HN, but figured I would share this for anyone who wants to take a look :) feedback always welcome!

[Other] Show HN: OpenSnowcat – A fork of Snowplow to keep open analytics alive I’ve been a long-time Snowplow user and unofficial evangelizer. I have deep respect for its founders, Alex and Yali, who I met a few times.<p>What made me fall in love with Snowplow was that it was unopinionated, gave access to raw event data, and was truly open source. Back in 2013, that changed everything for me. I couldn’t look at GA the same way again.<p>Over the years, analytics moved into SQL warehouses driven by cheaper CPU&#x2F;storage, dbt, reproducibility, and transparency. I saw the need for a democratized Snowplow pipeline and launched a hosted version in 2019.<p>In January 2024, Snowplow changed its license (SLULA), effectively ending open-source Snowplow by restricting production use. When that happened, I realized the spirit of open data and open architecture was gone.<p>A week later, I forked it, I wanted to keep the idea alive.<p>OpenSnowcat keeps the original collector and enricher under Apache 2.0 and stays fully compatible with existing Snowplow pipelines. We maintain it with regular patches, performance optimizations, and integrations with modern tools like Warpstream Bento for event processing&#x2F;routing.<p>The goal is simple: keep open analytics open.<p>Would love to hear how others in the community think we can preserve openness in data infrastructure as “open source” becomes increasingly commercialized.<p>That&#x27;s it, I should have posted here earlier but now felt right.

[Other] Show HN: I built a tech news aggregator that works the way my brain does An honest to god, non-algorithmic reverse chrono list of tech news that passes my signal-to-noise tests, updated hourly.<p>A lightweight a page design as I&#x27;ve been able to keep; simple, clean, fast. No commercial features or aspirations - this is a passion project, something I&#x27;ve been fooling around with on and off for decades.<p>There&#x27;s a &quot;Top&quot; view too with an LLM edited front page &amp; summary, and categorized views for a large number of topics - see the Directory. A few more buried features to explore, but the fundamental use case is pop in, scan, exit - fast and concise.<p>Your feedback would be appreciated!

[Database] Show HN: Pg_textsearch – BM25 Ranking for Postgres I built pg_textsearch, a Postgres extension that brings proper BM25 ranking to full-text search. It&#x27;s designed for AI&#x2F;RAG workloads where search quality directly impacts LLM output.<p>Postgres native ts_rank lacks corpus-aware signals (no IDF, no TF saturation, no length normalization). This causes mediocre documents to rank above excellent matches, which matters when your LLM depends on retrieval quality.<p>Quick example:<p><pre><code> CREATE EXTENSION pg_textsearch; CREATE INDEX articles_idx ON articles USING bm25(content); SELECT title, content &lt;@&gt; to_bm25query(&#x27;database performance&#x27;, &#x27;articles_idx&#x27;) AS score FROM articles ORDER BY score LIMIT 10; </code></pre> Works seamlessly with pgvector or pgvectorscale for hybrid search. Fully transactional (no sync jobs). Preview release uses in-memory architecture (64MB default per index); disk-based segments coming soon.<p>I love ParadeDB&#x27;s pg_search but wanted something available on our managed Postgres. You can try pg_textsearch free on Tiger Cloud: <a href="https:&#x2F;&#x2F;console.cloud.timescale.com" rel="nofollow">https:&#x2F;&#x2F;console.cloud.timescale.com</a><p>Blog: <a href="https:&#x2F;&#x2F;www.tigerdata.com&#x2F;blog&#x2F;introducing-pg_textsearch-true-bm25-ranking-hybrid-retrieval-postgres" rel="nofollow">https:&#x2F;&#x2F;www.tigerdata.com&#x2F;blog&#x2F;introducing-pg_textsearch-tru...</a><p>Docs: <a href="https:&#x2F;&#x2F;docs.tigerdata.com&#x2F;use-timescale&#x2F;latest&#x2F;extensions&#x2F;pg-textsearch&#x2F;" rel="nofollow">https:&#x2F;&#x2F;docs.tigerdata.com&#x2F;use-timescale&#x2F;latest&#x2F;extensions&#x2F;p...</a><p>Feedback welcome, especially from folks building RAG systems or hybrid search applications.
