cherry-pick packages in nix between channels

Using nVidia as an overpriced output adapter for AMD

Original problem

  • Monitor with only DVI free port that supports native resolution.
  • Tired from nVidia tension with Linux and switching to AMD.
  • New AMD cards and built-in have no DVI output and adapter will arrive late.

Solution: use reverse prime with nouveau

It is well described in https://wiki.archlinux.org/index.php/PRIME#Reverse_PRIME But in this case I want to use AMD as a primary and nVidia as a "Source Output" which nouveau supports.

Budgeting with hledger

The main answers I need from budgeting:

  • How much extra money I can spend without compromising ability to pay my bills?
  • How big my earnings should be to cover my expenses?
  • How can I optimize my expenses?

Tracking your expenses

One of my favorite reports hledger supports is
