How to convert Audible aax files to mp3 in Linux

 
Convert Audible aax-files to mp3 in LinuxSo far I always assumed that when I buy music or audiobooks on Amazon for download, I’ll get mp3 files for download. Far from it – yesterday I once again bought a an audiobook and had to find out that I was forwarded after the purchase to Audible and there was confronted with a “protected” aax file. If I wanted to buy at Audible, I would have gone to Audible. Thanks for nothing, Amazon!
But now the following question arises: “How do I convert the proprietary aax files into mp3’s, which I can play everywhere?” (aax files are only playable with the official Audible apps which aren’t available on all platforms.) After all, when buying on Amazon, there wasn’t the talk about the fact that the purchased audiobook can […]

How to disable PHP OPCache for certain directories

Deactivate OPCache per folderIn this article, I want to show you how to disable the OPCache based caching for certain directories. (If you need a short introduction to the subject of OPCache, you should scroll down to the blue box in this article.) Although OPCache is a good idea in almost all cases, there are, as with many thing, situations where you should make an exception. Especially when it comes to the development or if a bugfix is to be tested, it can make sense to disable OPCache.
However, since other projects that benefit from OPCache are often running on the same web server, a complete deactivation of OPCache for such test cases can not be an option. Therefore, this article is about how to disable OPCache on the directory level.

How to install and configure Roundcube

 
how to install roundcubeToday we’ll be talking about installing the webmail client Roundcube on your website or web server. However, before we begin I’d like to say a few words about why a webmail client is a good idea in the first place and why I decided to use Roundcube. If you’re just interested in the installation procedure, you can skip directly to the next paragraph (“Basic requirements”).
Why install a webmail client? I can answer that question only for me and my specific case. I have several email addresses – one is a Gmail address and the others are addresses for my websites and blogs that all have the format @website-name.net.
So when I want to see my emails, I don’t want to open five different websites and three programs. I’d like for everything to be in one place. […]

RadioduinoWRT – a do it yourself webradio

RadioduinoWRTToday I want to present you one of my larger craft projects. This time it is not just about software, but also about the associated hardware. What is it? A web radio!
I like to listen to internet radio stations, but I didn’t want to run my pc only for listening to webradios.  Connecting my phone to my stereo either wasn’t a solution, since I’d rather wear this with me, because I don’t want to run for each SMS / Whatsapp message to the music system. And because I always like to tinker, it was obvious to build a web radio as a standalone device myself.
As this article has become a bit longer, there is a brief overview of the following sections of the article, so that everyone can quickly find what he looks for.
