My chrome os dev setup

Ran on my Dell XPS 15 9560 (4k) using brunch with the rammus recovery

Why?

Mostly funs.

Findings

Great things:

  • Battery seem to be better than linux, equal to windows.
  • With normal usage laptops doesn't get hot even while wathcing 4k videos on youtube. Note that this also results in way less often the fan ramping up :)
  • Crostini works great and is by default setup to passtough localhost.

My gentoo cheet sheet

Install vscode

sudo emerge eselect-repository
sudo eselect repository enable pentoo
sudo emaint sync -r pentoo
su -c 'echo "app-editors/visual-studio-code ~amd64" >> /etc/portage/package.accept_keywords'
sudo emerge app-editors/visual-studio-code

A cheatsheet for installing FreeBSD

Corsair keyboard not working

Press the win key lock + F1 for 3 seconds. (this puts the keyboard in some kind of special mode where it behaves like an old keyboard)

Deafult programs

pkg install vim nano sudo

How i use windows for development

My Windows dev setup / howto

Rambelings

Ya windows the worst os to program on or is it.
For a long time i've been fully againced windows and i still kinda agree if you use it without "cheating". Windows it just too unstable and too un-standardized to work with on it's own, it's like using mac os with it's forever taking updates but combined with non-standardized tooling and a lot of unexpected bahavior what just results in a lot of frustration.
For example why can i see ls taking time to display lines in powershell???, ya it's only ~50ms but still why does a simple command like ls has to take so long??
Or why sometimes do programs not stop running when i press ctrl+c and do i need to open task manager and scroll to the program because there is no search bar so i can find it quickly??
