JavaScript

The bug you've encountered is a tricky one, and it has to do with something called Variable Scoping and Closures. This means that when you define a variable using var, it's important to understand where you can refer to its value, and when its value changes.

What's happening in your code is that the entire for loop is running to completion before any of the buttons are clicked. That means that by the time any of the buttons are clicked, the btnNum variable has a value of 3. Why 3? Because the loop increments btnNum to the first value that btnNum < prizes.length equates to false. So, even though you define the onclick handler each time the loop iterates with a different value for btnNum, the alert(...) statement only runs at the end of

Installing NixOS on the RockPi4 (B)

The general plan is to build an sd-image-aarch64 from nixpkgs/nixos/modules/installer/cd-dvd/sd-image-aarch64.nix flash it to the eMMC and have the system come up, similar to how this “just works” for raspberry-pis.

The RockPi 4 is a RockChip RK3399 based board, build by radxa with the same formfactor as a rasperry Pi. One noticable difference is that the Rock Pi’s cpu is at the bottom to better allow for the
