Show HN: Vizier – A physical design advisor for DuckDB Hi, I've made an early version of a physical design advisor (called Vizier) for DuckDB. It can analyze a collection of queries (using a set of heuristics) and recommend changes to the physical design/layout of the database (for example, sort orders, Parquet layouts, indexes, etc.), in order to make those queries run faster. Vizier is implemented as a DuckDB extension in Zig and supports DuckDB version 1.2.0 and newer. The project is very early-stage, but if you're interested in learning more about Vizier or trying it out, you can check out the links below: Project's GitHub repo: https://ift.tt/yTxFOc2 Vizier documentation: https://cogitatortech.github.io/vizier/ March 26, 2026 at 11:46PM

Show HN: Micro – apps without ads, algorithms or tracking For over 10 years I've been trying to accomplish something that took Claude Code and a lot of failure to realise. We need alternatives to big tech and we're not working hard enough to make that happen. In an era of addiction, usury and exploitation it's now time we seriously consider alternatives. Proton and the like worked on privacy focused individual services at a pain stakingly slow pace. Maybe for good reason. But it was also in an era pre AI. 10 years ago I was convinced the super app model would work. And that a platform needed to exist to facilitate that. Today I realised the tech doesn't matter, the idea and execution from the top down does. I put aside my technical perfectionism to try pull together a solution to some of the problems that plagued my own life with tech addiction and I rewrote and threw away this thing multiple times over the years pre AI and after. I burned VC funding, I burned bridges, ...

Show HN: I built a site that maps the web from a bounty hunter's perspective I built this because I wanted my own directory of public companies running bug bounty programs — where I could see their infrastructure in one place and have a real idea of where to start poking holes. Neobotnet collects intel data from companies on HackerOne and Bugcrowd — subdomains, DNS records, web servers with status codes, indexed/crawled URLs, JS files, and exposed secrets/paths (still building this last part). The data is already there when you need it. No scans to run. Currently tracking 41 companies, 63,878 web servers, and 1.8M+ URLs. Long term I want to expand this to startups that depend on cloud infrastructure so they can see what's publicly accessible. Made a free sample with Capital One's data (and other companies) so you can see what it looks like without signing up: https://freerecon.com Original Page: https://neobotnet.com Feedback very welcome. https://ift.tt/26PByHG March 24, 2...
