With the kitty terminal, you can send desktop notifications with the following (example taken from the kitty docs):

printf '\x1b]99;i=1:d=0;Hello world\x1b\\'
printf '\x1b]99;i=1:d=1:p=body;This is cool\x1b\\'

For details about how this works is here.

Small app to detect and show fixed Nerfont moved codepoints

I wrote versions in golang and rust.

With golang it was a walk in the park but I've writen a lot of go.

I just started learning rust and oh boy did I struggle 😅

nushell script to watch for changes

export def --wrapped aws [...rest]: nothing -> list<any> {
    if ($rest | last) == "help" {
        ^aws ...$rest
    } else {
        ^aws --output json ...$rest | from json | get-first
    }
}

export def "get-first" []: record -> any {
    let input = $in

Getting machines from all clusters in nushell

I'm migrating karpenter to version v0.32.x and I need to verify if there are some machines left that might not have been migrated to nodepools.

Note

I have a none context that I select to "turn off" kubectl. I need to filter it out. To create this context, I used the following command: kubectl config set-context none

let machines = ^kubectl config view

Get all AWS VPCs, for all accounts, in all regions, in nushell

The cool thing about this script is that it uses par-each to run the aws commands in parallel and collecting the results. Do you know how hard that is to do in bash?!

Warning

This script assumes that you have 1 profile entry for each AWS account of the form <account alias>/aws-read-only. Adapt as needed.

aws configure list-profiles | grep aws-read-only | lines | par-each {|profile|

Sometimes in the course of your job you might need to approve a bunch of pull requests that were automatically created.

The gh cli is a handy tool to simplify this process.

In this example we'll approve all pull requests in the Foo org that request you as a reviewer and contains autoscaling:

for PR_URL in $(gh search prs org:Foo --review-requested @me --state open autoscaling --json url --jq ".[].url"); do
 echo $PR_URL
