  • Asana cleared 5 years of engineering work in 2 weeks with Codex
    Since when? https://learn.chatgpt.com/docs/codex/cli https://github.com/openai/codex Looks like it's still a more-or-less-open-source product called Codex CLI. FWIW, there have been issues with various versions of ChatGPT not knowing what Codex is -- at least in the (IIRC) GPT-5.3 timeframe, there were serious issues with the knowledge cutoff. - Source: Hacker News / 15 days ago

  • Honukai Color Theme Goes IDE
    Honukai has long been my favorite iTerm, Oh My ZSH color theme, and I just assumed it existed for other use cases. But alas, I had to create them for myself. I adapted Oskar's work for Tabby terminal, ZED IDE and VS Code. You can get the files here. - Source: dev.to / almost 2 years ago
  • What kind of applications are missing from the Linux ecosystem?
    I've found Tabby does a good job and is Cross-Platform to you can use on Windows too. It can run any installed shell, serial connections and ssh. You can create profiles. It needs some work to be fully functional in Wayland i.e. Autohide feature doesn't work. But that's a graphical issue. Though, if you're just after creating and organising SSH profiles not terminal emulation, Remmina already has you covered.... Source: over 3 years ago
