Better WLED LEDMap Generator

Code to create a WLED LED-Map (the JSON that tells WLED the positions of the LEDs) with some features that I didn’t find in any online editors: Dragging the mouse over the canvas fills all hovered cells, rescaling the map to a different size, inverting, and inserting LEDs in between existing ones.

Adding dynamic content to HUGO

This website is build using Hugo, a framework to generate static websites from markdown-files. This means that after the compile-step, there are only pure HTML-files, which can just be hosted on any webserver. While this has several advantages in terms of eg. speed, debugability, search engine optimization and much more, a big disadvantage is that there is no straightforward way to include dynamic content. As everything is unchanged from the compilation on, allowing for content dependent on user input or from real-time data, or just including content generated from other web frameworks such as Python’s flask or Django, is not easy. However, thanks to Javascript, it is absolutely possible to incorporate such dynamic content, as I have done for example in my CV, which is generated with my custom CV-Generator.

Mount a QNAP NAS to your system using SSHFS

I never really liked NFS, so I wanted another way to mount a drive from my QNAP NAS onto my linux machine. As I haven’t found any sort of instruction for that online, I’ll post how I did it here, in case anybody searches for the same thing.

The how is hurdled mostly by the fact that you cannot install SSHFS onto QTS, as the package ist not available for it. But as so often, the solution is Docker. We’ll just create an Ubuntu-Container where we can install SSHFS, and mount the directory we want to share as a volume. This of course requires that you have a NAS with Container Station, allowing to use Docker Containers.
