    When you have two monitors, is your head always turned to one side? That always hurts my neck, so I wind up with the second monitor relegated to the side, where I never actually lo…

    There are languages like Dafny that permit you to declare pre- and post-conditions for functions. Dafny in particular tries to automatically verify or disprove these claims with an…

    And If `jj absorb` gets it wrong, you can run `jj undo`. This is such a killer feature to me. I'm not scared to start potentially gnarly rebases anymore because I can painlessly un…

    I've never verified this, but it feels like scp starts a new TCP connection per file. If that's the case, then scp-ing a tarred directory would be faster because you only hit the s…

    Show HN: Artificial Ivy in the Browser

    This is just a goofy thing I cooked up over the weekend. It's kind of like a screensaver, but with more reading and sliders. (It's not terribly efficient, so expect phone batteries…
