Show HN: hnsubstacks – Browse only Substacks submitted to HNhttps://hnsubstacks.com/I made an HN clone that lists only Substacks posted here.- Why? Over the years, I've discovered some great blogs here, so I thought it would be nice to have a filter for them.- Why only Substacks then and not blogs more generally? Because it's easy to query for "substack.com" in the public HN Algolia API (see below). Plus, hnblogs was already taken :)- What about substacks on custom domains then? At the bottom of the page there is a form to submit a custom domain. The site attempts to auto-validate that it is a Substack. If that fails, it is marked for manual review (which I'll do every once in a while). Approved ones will be included in the results.- How? I use HN's Algolia API to fetch substack stories by searching for "substack.com" in the url. I do this via a CloudFlare worker that has 3 separate cron triggers: (1) fetches new stories every 10 minutes and saves them in a KV store. (2) runs 2 minutes after the first, computes hot stories from new ones by simulating HN's score algoriJul 7, 2026 2:31 PM

Show HN: Fast, native Mac file manager (filters, fuzzy find, 9 MB, no Electron)https://whimfiles.comMy Downloads folder had been left unkept for a really long time and cleaning it up using Finder was quite cumbersome. So I started creating a simple app to help me filter out and delete or move the files in the folder.It started out very basic and the filtering options genuinely helped me clean out the Downloads folder, then as I thought of more features I would like to see in a file manager I started to add them. Some of the features are:- Fuzzy go to folder/file where you only need to write a few letters of a full path, get suggestions and can jump to the correct path instantly - Hover over a file to preview an image or PDF without opening it - Dual-pane view and tabs that remember selected filters - Command palette to find actions fast - Batch rename (with regex support and presets for common operations), image conversion (HEIC/WebP/AVIF to JPG/PNG), zip creation - Bookmarks, Quick Look, single-click open, keyboard controlAnd many other small quality of life features.I used Claude CJul 7, 2026 8:12 AM

A fleshed-out IPv5 proposalhttps://news.ycombinator.com/item?id=48781622Over 30 years after its introduction, IPv6 has still not replaced IPv4. I've seen those "just add more bits to ipv4, call it ipv5" proposals before. They tend to skip the important details and talk past others, but they have a point. After filling in the details over time, I think this actually works, it'd make a serious difference, and it's doable with the current IPv6 header.Background...Let's assume the IPv6 packet format is already sufficiently supported on routers, hosts, etc. That's not the blocker anymore, rather plenty of ISPs, web services like Github, and corporate networks have chosen not to adopt IPv6. Home routers just enable it, but it's nontrivial for services because it's a separate network from v4 in every way, requiring extensive config changes. End result, almost everyone needs a v4, while many use v6 but don't depend on it.IPv6 absolutely needed a new packet format to support >32-bit addrs. But it made more choices beyond that, largest of which was starting with a fJul 4, 2026 12:43 AM
