  • For the most part it’s best to use system provided sorting implementations, but somebody has to write those implementations, so every once in a while somebody needs to do it (in practice by looking up a reference implementation of course).

    But also it’s good to understand things like big O scaling and why we use quicksort rather than a naive insertion sort and when to use quick sort vs merge sort or some other form of stable sort.


  • I looked into building my own keyboard, and then realized there are some excellent hobbyist tier keyboards that are 99% of what I would have wanted from building myself for like 30% of the cost.

    I’m using the Hexgears Gemini Dawn right now, and I’m quite happy with it, but if I were to get a new one today I might go with something that supports QMK like the Massdrop CTRL.

    The main 2 features I look for are hot-swappable switches and programmable firmware. Personally I like an aluminum frame and look for that as well.

    You’ll pay about $100 for a prebuilt vs like $500 for building it yourself









  • The multiple power supplies are for redundancy. It will work with one plugged in but you are “supposed” to plug in both.

    It’s fundamentally not that different from a consumer desktop. Plug in a monitor and a keyboard and a USB with your preferred flavor of headless Linux installer on it. Configure ssh as the first thing you do because you won’t want to plug the monitor and keyboard into it every time you need to tweak something.

    You can probably find VGA to HDMI adapters if you can’t find a monitor with VGA support.
