Notes

Cowsay is one of those packages you just end up installing randomly on just about any client over time.

And if your using ansible you may be in for a little surprise:

Django’s CSRF protection is usually a great thing, but when building (API) endpoints meant to be accessed by scripts/third parties it gets in the way of that.

This is how to disable it:

For a class based view

from django.utils.decorators import method_decorator
from django.views.decorators.csrf import csrf_exempt

@method_decorator(csrf_exempt, name='dispatch')
class MyView(View):
    pass

For a function based view

from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def my_view(request):
    pass

Since early 2019 the sprig library used by helm provides a concat function that does exactly this.

Go check out their website, it’s incredibly good at explaining itself.

To me, a backend heavy developer, HTMX is the frontend framework I like to use because:

• It does not feel like a JavaScript framework at all, but more like an extension of the HTTP/HTML model
• It allows me to write interfaces that feel responsive and modern to users while still doing all the heavy lifting in my backend with the tools I’m used to
• It works with my mental model, which is heavily based on the request-response cycle

Think before you enable this, it could be a security risk

• Shutdown Mac
• Press and hold the power button until the Recovery Mode menu appears
• Select Options, then click Continue
• From the Utilities menu select Startup Security Utility
• Select your startup disk and click Security Policy
  • Choose Reduced Security
  • Check the option Allow user management of kernel extensions from identified developers

The 1Password CLI op works either in connection with a client app, like on the Mac, or standalone, useful on a server.

# Login
eval $(op signin)

# Get favorites
op item list --vault "Private" --favorite

# Get a specific item
op item get <ID>

# !! Important: Sign out at the end
op signout

Some helper functions

Helpers to more easily work with the op cli.

1login() {
    eval $(op signin)
}

alias 1signout="op signout"

1search() {
    term=$1
    if [ -n "$2" ]
    then
      vault="$2"
    else
      vault="Private"
    fi
    echo "Searching for '$term' in vaut '$vault'"
    op item list --vault "$vault" --long | grep "$term" --ignore-case
}

1get() {
    op item get $*
}

Things I do to be a good code reviewee.

A simple Python client to interact with ArgoCD.

The problem

If you use ssh-agent with an encrypted ssh key it does not persist when you open a new terminal window.

The solution

Use keychain instead.

1. Install

   sudo apt install keychain
   

2. Add to your shells rc file, eg. .bashrc or .zshrc

   # Repeat this line for all keys you want to unlock and use this way
   /usr/bin/keychain -q --nogui $HOME/.ssh/id_rsa
   source $HOME/.keychain/wsl-sh
   

3. Unlock your keys on shell startup and enjoy

Sometimes you may want to commit only the files you have changed and not any newly created files, this can easily be achieved by this command: git commit -a

This is my checklist for publishing a new post on my blog:

Preparation

• Finalize the posts name and sluggify it
• Pick a image if fitting
• Create a new post with hugo new content/posts/<slug of post>.md
• Move the draft from my current writing tool to this new file
• Fill in the generated front matter template
• If the post is ~1.000+ words enable the TOC
• Run spell-check in VSCode and fix things

Proofing

• Run local hugo server hugo server -bind=0.0.0.0
• Wait at least an hour
• Open the locally served page on the iPad, grab a cup of tea and read it
• Make last changes and typo fixes as needed
• Place a `
