Our weekend project - HN Showcase, browse "Show HN" posts

In plain words

HN Showcase is a visual browser for "Show HN" posts from Hacker News, letting users discover projects that may not reach the front page. It displays thumbnails of submissions and allows sorting by date, points, or comments, with keyboard navigation support. Built using the HN Search API and thumbnail generation services, it makes finding interesting projects shared on Hacker News easier and more visual than the standard interface.

From the sources

The AI-powered visual front page for Show HN. Browse, filter, and discover the best projects launched on Hacker News.

AI agent that designs KiCad boards end-to-end, gated by ERC/DRC and spec validation. Catches regressions AI code review misses by tracking behavioral guarantees, not just diffs. Temporal GraphRAG on Postgres that beats Zep/Graphiti 94% vs 71% on LongMemEval. Per-boundary access profiles for AI agents, but it's a docs page for an unproven product. Discover, mask, and verify sensitive data in SQL databases — an auditable scan → mask → validate workflow for safe database copies. Scan-mask-validate workflow for SQL data masking with row-by-row verification of the result. Faster rsync alternative with parallel connections, persistent SSH, and remote-to-remote transfers.

In the maker’s words, at launch

http://www.hnshowcase.com Moses (nnythm) and I browse Hacker News daily. Show HN posts are some of our favorite parts of HN. We wanted to create a way to browse Show HN articles, even those that might not quite make it to the front page. We created http://www.hnshowcase.com last weekend to make discovering projects…

  Find Hidden Gems on HN2025 · pj4533.com · ▲118

  Hey HN. I created this website. https://pj4533.com/hn-overlooked/ It's just a simple web app that discovers overlooked posts on Hacker News. I created it because I was often coming to Hacker News and realizing that I was missing a lot of stuff, and there just didn't seem to be an easy way to surface content that was interesting to me but just didn't bubble up to the top of the page. So I built this. I got the idea a while back, one night when I was recording (you can watch it here, it's pretty funny: https://youtu.be/FDyDb4sX30w?si=E3rby-DaGWA6gy0R ). But I…

  Analyzing top HN posts with language models2022 · ▲117

  Hi HN, I spent a few weeks looking at the top HN posts of all time. This included exploration, clustering, creating visualizations, and zooming in on what (to me personally) seems like some of the best discussions on here. Three things in this post: 1- The interesting groups of HN posts 2- The interactive visualizations that you can explore in your browser 3- The data from this exploration -- this includes CSV of the titles as well as the text embeddings of 3,000 Ask HN articles. Blog post about this whole process here: [1] ============ 1- The interesting groups of HN posts From the…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Codecademy.com, the easiest way to learn to code▲787

  I've been a longtime member @ HN, but I haven't been a developer. In fact, my only HN submission has been one asking how to learn to code (http://news.ycombinator.com/item?id=820741). My cofounder and I decided to solve the problem by making a simple, interactive way to get started with Codecademy. We'd love your feedback. If you're interested in helping us to get more courses up (on any topic!), please send us an email at [email protected].
