    inoTecCast - Linux

    Auf der letztjährigen inovex Weihnachtsfeier habe ich Nico kennengelernt. Er hat sein eigenes Podcastformat, die Techtiefen, bei dem er mit Sofwareentwicklern über aktuelle Technologien und Technik spricht. Es geht um Security, Data Science, Cloud Technologien und Programmiersprachen. Nun hatte ich letztens die Möglichkeit mit Nico zusammen eine Folge aufzunehmen und ich durfte über Linux erzählen.

    Das Ergebnis könnt ihr hier nachhören: Techtiefen - 14 Linux.

    Domain discontinued

    On Jan 19th, 2019 – in one year – we discontinue the domain After this date the domain, webpage and email is not under our control. We are not responsible for the content anymore.

    Currently – Feb 10th, 2018 – the webpage still hosts a simple webpage and javascript counter being a placeholder for an old drupal installation that a friend of mine and I hosted for our school and class mates. It was a lot of fun to create and build this website back in 2008/2009. Since our school days are already a long time ago we decided to cancel the domain contract for the domain

    If you want to see the simple webpage and counter after the domain contract has expired, you can visit I have reuploaded the html and javascript under a subdomain of so you and I look at the slowly but constantly increasing seconds since we left school and conquered the world.

    Yocto Recipes vs Packages

    While working with the Yocto/OpenEmbedded build system on a daily base I have learned a lot about the inner workings and maybe have already hit any pitfall that it contains. But while debugging and digging through the source code, I have always learned something new and have understood more of the magic.

    Since I didn't found any good explanation about the differences between recipes and packages, which is fundamental in the build system, here is my explanation: There is a nice to read blogpost More on Yocto Terminology – recipes and packages by Christopher Hallinan posted 2012, I found yesterday. Infact it was not hard to find. I you want to read another explanation, here it comes:

    How to do a basic and simple Yocto build

    The Yocto Project is an effort by the Linux Foundation to make building Linux based systems for embedded devices easier and more consistent. The community and industrial partners develop and maintain the Yocto build system. It consists of the reference distribution poky which is bundled together with bitbake, openembedded-core and an extensive amount of documentation in a git repository that is also called poky. Other known buildsystems for embedded devices are: ptxdist, buildroot and openwrt.

    In the last three years of my professional software developer life I used and work with the Yocto build system. As with every piece of software you use in your daily work, I have learned to hate it :-) Since the internet lacks some good and brain-dump copy&paste guides to just try out and build a poky image, here is it. My step by step guide: How to do a basic and simple Yocto build.

    I use the name simple instead of minimal for these build instructions, because you do not have to configure at lot of stuff. It works out of the box and should work reliable for different versions of poky.

    It's also not minimal because the build requires 30 GB of disk space and needs to download 5.2 GB of source code archives.
