Omarchy is an opinionated Arch distro created by David Heinemeier Hansson (DHH), creator of Rails, Basecamp and Hey. Under the hood it's Arch Linux + Hyprland, but it ships with everything pre-configured: lock screen, menu bar, bluetooth, themes, keybindings. No installing packages one by one.

This is a static site generated with hugo with the PaperMod theme. I wanted an easy to use static site generator. I considered Jekyll and believe it to be a good choice for static sites. There seemed to be slightly more themes I liked with hugo so I went with that. That's a pretty superficial choice but I also don't plan on hacking on the site generation itself so I was agnostic to the Go versus Ruby choice.

Project mention: Supercharge your macOS workspace management with Aerospace - A guide for busy people | dev.to | 2026-06-06
Aerospace is a menu bar application, but you can’t download it from an App Store or get it as a DMG file. You need a package manager. Go to the Homebrew website and follow the installation guide. Make sure to accurately follow the on-screen instructions. This may include any of the following:

Project mention: Pressure-testing Ota on Discourse: repo-wrapper truth matters more than a passing bundle command | dev.to | 2026-06-06

It’s a popular automation target for mobile projects.
App Stores require screenshots, but generating N images for NUMBER_OF_SCREEN_SIZES times NUMBER_OF_LOCALIZATIONS can be a chore.
In the past I wrote my own scripts for that, today tools like Fastlane[1] help.
I use Fastlane for my logic puzzle game Nonoverse[2], I like it a lot; you can see sample screenshots in the App Store page.
I also automated App Preview video recording, complete with multiple scenes. If anyone wants to read more let me know, perhaps this is a good topic for an article.

Project mention: I Ditched Docker for Podman (and You Should Too) | news.ycombinator.com | 2025-09-05
Yeah, I was actually participating in a soft-fork for a while but I think the project ran out of steam. My guess is that it's very hard to pay attention to something that you don't use every day, so they let it drift. But if you ever hear of someone starting up again, let me know
I'm aware that I, too, could be the someone but like I said it's hard to dedicate all the time and energy when the last time I used vagrant was years ago
I also just remembered that I haven't revisited the forks list to see if there's some meaningful activity https://github.com/hashicorp/vagrant/forks?include=active&pa...

If you use a different tool, you're encouraged to open a PR or Issue on Forem to add a new parser yourself or ask us to do so. As an example, you can check out how our Gemini CLI parser works in our GitHub commit: https://github.com/forem/forem/commit/8f92c64a775ed3a0993e5edc0637112a95d1dae2#diff-d98a98bdd6e0d9154df5559b53644185d4ab13160e85c0fdaae3013ff985e27b

Anyway, RestlessIDE features OpenProject, a (you guessed it) open-source software package that lets you create and assign tickets, set timelines, build Gantt charts(!), write wiki pages, and manage your projects through whichever strategy works for you. Your whole team on RestlessIDE can log in using the same credentials, and you can configure it to send everyone emails at an alarming rate just like Jira, if you want to.
