Linux Kernel Modules for NixOS

You can find what kernel modules are loaded using lsmod.

However some kernel modules are required at stage 1 boot. Basically preloaded in the initial ram disk before switching to the root filesystem. These kernel modules are mostly needed to deal with peripherals, storage devices, filesystems and network devices. You may need to be wary of these required modules:

• sd_mod - SCSI, SATA, and PATA (IDE) devices

GoPro on Linux (NixOS)

The GoPro Hero 7 uses MTP for transferring files. To connect on NixOS you need to have MTP.

The best GUI tool for MTP is gmtp. Connect your GoPro and use gmtp to transfer files.

For more advanced interaction with GoPro devices, see https://github.com/NixOS/nixpkgs/pull/65607

Ideas in HTTP Restful API

Pagination

Pagination should always be using 2 parameters: seek and limit.

The seek is the offset into the collection.

The limit is how many to items to acquire.

// you often want to check if a value is truthy
function booleanise(v) {
  return !!v;
}

booleanise(0) // false
booleanise('') // false (empty strings is falsey)
booleanise(false) // false
booleanise(null) // false
booleanise(undefined) // false
