    After finding a much-needed network cable under a pile of junk in the basement, I decided it was time to add cleaning up the basement to my to-do list. To manage personal tasks (even unpleasant ones like this), the dstask personal tracker can help you prioritize tasks and track completion.

    Unlike many other task managers, dstask exclusively runs on the command line. With a short and succinct command, you can add a new task or mark off a completed one. On request, dstask provides a list of all pending tasks, sorted by urgency. Filters help you stay on track in the task jungle. As an added benefit, you can use your task list to show customers or your boss your completed work.

    Under the hood, dstask stores the pending tasks in the Git version management system, letting you sync tasks across all your devices. However, unlike dstask's other features, synchronization requires some Git know-how.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers.
