Often times we need the current date (and time) when scripting inside bash or other shells. For example when creating a backup file or writing to a log.

Sometimes it is useful to wait for a port to be closed, for example when updating an app that can’t always properly be shut down using other Ansible modules.

This can easily be achieved using the ansible.builtin.wait_for or ansible.builtin.win_wait_for module.

My preferred minimalistic CSS framework, which is usually enough for small websites and even simple SaaS apps. It feels like a super power to write almost plain HTML and get something that looks presentable, supports dark mode and has just enough components to cover most use cases for me.

Often times when writing scripts I want to reference files in the same directory, but keep the script portable in case it is part of a git repository being checked out somewhere else or just the folder getting moved.

I was recently doing a lot of layouting pages to later be printed, so showing how big certain elements are was of help to me.

This is a JavaScript function that does just that.

Using flex children can easily be positioned vertically in their parent container.

When debugging issues with CSS layouts it can sometimes be tricky to really understand what is going on.

I often find myself wanting a simple copy button in my web projects.

This is the recipe I build them from using clipboard.js and a couple lines of JavaScript.

Sometimes, when working with externally generated content you might want to make links clickable when rendering it in the client.

This is a snippet to do just that.

Debugging container workloads can be a challenge sometimes, especially when running them in k8s, behind a reverse proxy or in other, possibly complex, traffic flow scenarios.

Sometimes, mostly when throwing together a quick idea or MVP, it can be useful to just register all models with the admin and leave proper customization for later.

How to add things to a list using kustomize. This is useful for example when you need to patch additional environment variables into a pod.

I often whish to search through large bodies of text, like my knowledge base or source code repositories, from the command line.

I use fuz for this and I’m quite happy with it.

I also have it aliased to my knowledge base folder for even easier searching.

alias search="fuz -p /path/to/knowledge-base/"

Copy & paste from untrusted sources on the internet into the terminal is a really bad idea! Early in my career I did it too and still often see others doing it.

Hugo is my favorite tool for publishing markdown to the internet, but sometimes I want to do something a little bit more advanced with my posts.

With this shortcode I can always just fall back to plain old HTML.

The HTML details element is a nice way to create natively expandable content with wide browser support.

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

I write an extensive personal knowledge base using markdown, code-server and a variety of other tools. Originally, in 2021, I wanted to have something like Obsidian Publish but self-hosted, so I created it.

Over time my knowledge base evolved more into a second brain, tracking not only my technical notes and journal, but also things like recipes and hikes. With this my publishing pipeline, and the script at it’s core, extended in a multitude of ways.
