Create a new directory in wp-content/themes — let's call it danktheme in this example. Create two files in that directory: style.css and functions.php with the following contents:
/*
 Theme Name:   Your Themename
 description:  Your Description
 Author:       Your Name
 Template:     twentytwentyone
 Version:      1.0.0
*/
and
<?php
add_action('wp_enqueue_scripts', 'my_theme_enqueue_styles', 11);
function my_theme_enqueue_styles()
{
    wp_enqueue_style('danktheme', get_stylesheet_uri());
}
That's it: now you can select "Your Themename" in the admin interface. If you don't want to use twentytwentyone as the parent theme — because it's not the most recent one when you read this, for example — replace it in the style.css. Yes, in the stylesheet, I'm not making this up, rules are rules.


I was always fascinated with the idea of turning ideas into data within a computer and then turning this data into a physical object. With this, I'm probably not alone given that 3D printing is all the rage in nerd world. After some googeling around and buying a printer on Amazon Prime day, I devised the following plan to learn 3D printing as a skill: 1. print sample shape shipped with the printer 2. print model from the internet 3. modify existing model 4. create a model from scratch The intention behind this plan was to spread out different problems and technologies involves as much as possible. So it's never a daunting task. Show the steps!


CTFd is a Python-based open-source Capture The Flag (CTF) web app. I wanted to use it in a context where I didn't want to collect email addresses of the registering users. To archive this, I decided to take the easy way and hack myself around the problem: just hide the email-field in the registration form and generate a random address for every registration. Show me the code!


All right, the last step to complete the great Sourdough Monitoring Project (SMP): capturing actual footage. We don't need a real video but just a sequence of still images. The goal is to collect enough of those on disk to later be able to assemble them into a time-laps video of the dough growing. First I'll show you how to enable camera support in software, then how to attach the camera, and finally finally how to capture images to disk. As a bonus, I'll share a PHP script you can use to receive images on a server on the internet so you can look at your dough from the other side of the world. Take a peek.


This is me again, having no idea about electronics and trying to get a Raspberry Pi to record the temperature of its surroundings in order to better control the environment of the previously mentioned sourdough. Get bakin'!


I want to create a stop motion movie of sourdough growing over night. Don't ask. Since I'm very comfortable with the OS, I am using Raspberry Pi as the hardware platform. And since everyone will tell you that _Lighting_ is important for any kind of filmmaking I played around with ways to toggle power on the USB ports to control USB-powered lamps.

I started learning JUnit 4 and encountered the message "1 of 4 branches missed." when testing a code fragment like x && y where x and y depend on each other in a particular way. Here is my journey and a "solution". You want to know more? !


Run
grep Revision /proc/cpuinfo
and look it up on https://elinux.org/RPi_HardwareHistory. For posterity I copied the table by the time of writing...!


I am currently comparing different virtualization solutions for my home. This is because I want to do all kinds of things like openhab, cronjobs, DNS-based adblocking, and gateways both in via SSH and out via different VPNs/Tor, and splitting those into different machines sounds not only reasonable but is also necessary in some cases when there are different operating systems involved. This blag post will document a few nuggets of knowledge I collected while trying out VMware as hypervisor. You want to know more?


The Zlob malware contains lots of bogus API calls to hinder analysis. This blag post describes how to use a script in Ghidra to automate the process of patching out those calls with NOP instructions. Is that even hard?!


Sometimes it really surprises me how something as mundane as JSON encoding and decoding datetime objects in Python is not readily solve-able with a simple google query. I guess this is caused by the sheer amount of code fragments floating around confusing The Kraken. With this blag post, I'd happily like to add to this mess: Show me your code snippet!


Since I already ran into this problem twice, here is a tiny reminder for my future self and potentially others that google something along the lines of the title. If you did docker pull arangodb at some point in the past, then ran a ArangoDB container for a while with something like the command blow and want to update, just follow the error messages! Follow them already!


Directing your attention as a reverse engineer is key for not wasting your life looking at irrelevant code. This blag post will use an anti-analysis technique used in the Zloader malware as an example to practice this art. We will also take a short detour into code-level obfuscation and are going to re-implement the API hashing function from Zloader in Python. This post is aimed towards reverse engineering beginners that have already heard about API hashing. If you don't know, what Ghidra is or how to use it, you will need to brush over some parts of this post. Tell me everything!
