Show HN: I scanned every YC Spring 2026 startup for what AI crawlers see Used 'potatometer.com' to scan and analyze all All 197 YC Spring 2026 startups on their SEO / GEO / AEO technical setup. I scanned the URL each startup lists in YC's directory. Most are readable by AI crawlers. Most don't tell a crawler what they are.

Show HN: A pure ARM64 Assembly web server, now on Linux with CGI for no reason This is ymawky, a now-dynamic web server written entirely in ARM64 Assembly. I've previously posted about ymawky here: https://ift.tt/Uni2SAg In the past month and a half, I've made some pretty major improvements: I've added CGI scripting support, so the server now supports query strings and dynamic content; and I've fully ported ymawky to run on Linux, rather than macOS-only. In addition to GET/PUT/HEAD/DELETE/OPTIONS requests, because of CGI support ymawky also accepts POST requests (only to CGI resources for now). I've also updated the more detailed writeup to reflect CGI support and the Linux port: https://imtomt.github.io/ymawky/ https://ift.tt/NkZ3Spa June 23, 2026 at 01:28AM
