Over the years, I’ve done the odd woodworking project, like building a guitar speaker cabinet or putting some shelves on the wall. I’ve used wood glue before, and I have (had) an ever-growing collection of all kinds of wood screws in my toolbox, mostly leftovers from previous small wood-related tasks. Up until a few months […]
After my recent post I did not stop tinkering and exploring. To my own surprise it didn’t take long to come across significant improvements to my toolchain. Someone contacted me on mastodon shortly after and said that a friend of his had also recently gotten into SDRs and ADS-B and decided to write his on […]

I’ll be escaping the grey, dark, cold and wet Berlin for a month. Last year I did the same and I wanted to be able to record a Glitterbrains podcast , record guitar and actually take guitar lessons remotely. Back then I brought my UA Apollo Twin with me so I could do some flexible […]

Intro Recently I was getting back into photography and as a result I was looking for a place to host my photos and share them with my friends without making them public to the whole world. Additionally I would like to see the photo’s EXIF information and other metadata. I do have an old flickr […]
In this blog post I will describe how you can dramatically improve the performance of your PHP CMS website that you’ve hosted at a webspace provider, in this case Hosteurope. To achieve this I’m using nginx, haproxy, varnish, s3 and Cloudfront CDN. A friend of mine is selling her designer brides dresses on her website […]
Podcasts are still quite popular and new ones appear everyday. It is a fantastic format and I encourage everyone to give it a try. This of course involves the process of recording audio and if you haven’t done that before, there are a few things to keep in mind to get the best possible result, […]
When I started skateboarding, I don’t know for sure but it was around the year 2000. For simplicity lets say it is more than 15 years ago by now. When you start skateboarding there are a few essential things you need: A skateboard and a pair of shoes. The rest is pretty much optional. In […]
