# Creates an alias called "git hist" that outputs a nicely formatted git log.
# Usage is just like "git log"
# Examples:
#   git hist
#   git hist -5
#   git hist <branch_name>
#   git hist <tag_name> -10
##
git config --global alias.hist "log --pretty=format:'%C(yellow)[%ad]%C(reset) %C(green)[%h]%C(reset) | %C(red)%s %C(bold red){{%an}}%C(reset) %C(blue)%d%C(reset)' --graph --date=short"

Mosh (mobile shell) is a gift from the Gods(tm). Anyone with spotty internet or wireless connection has suffered the pain of a lost SSH session. Sure, one can fire up screen (or tmux as the kids are using these days), but that's an extra step and you are still using the SSH protocol.

I'm not here to tout the benefits of Mosh, you came here to open it up in your firewall.

1. Create the following file as /etc/firewalld/services/mosh.xml
2. firewall-cmd --add-service=mosh --permanent
3. firewall-cmd --reload

If you tend to have a lot of sessions (not recommended), you can increase the ports, but the default should be fine for most applications.

You may find something like this a little simpler

zfs list -t snapshot -o name | grep ^tank@Auto | tac | tail -n +16 | xargs -n 1 zfs destroy -r

    output the list of snapshot (names only) with zfs list -t snaphot -o name
    filter to keep only the ones that match tank@Auto with grep ^tank@Auto
    reverse the list (previously sorted from oldest to newest) with tac
    limit output to the 16th oldest result and following with tail -n +16

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

Module supporting type-level programming

Introduction

Embedded software is often difficult to debug, so there is a strong motivation to catch as many bugs as possible at compile-time. However, the performance requirements of embedded software also make it difficult to justify changes that impose additional overhead in terms of size or speed. Ideally, we would like to add as many compile-time checks as possible while also producing the minimum possible assembly.

scenario: you have a windows vm failing to boot with INACCESSIBLE_BOOT_DEVICE and changing the disk type to ide or something else causes another bsod. how to you get it to boot up again without a physical machine?

download the stable virtio drivers from here, in iso form: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso

add the iso to your qemu/virt manager config as a cd/dvd drive

windows should send you to the recovery mode screen, but if it doesn't you might have to run a windows install iso to get to it.
