    #7: Config Management Camp: Kubernetes, Sysdig & Mgmt

    #7: Config Management Camp: Kubernetes, Sysdig & Mgmt

    I’m back! Sort of.


    This is a mono-episode where it’s just me talking about Config Management Camp, a conference held in Gent in February 2017. I recap a few interesting talks and projects I saw.


    This is an episode that I recorded in the car. So there might be audio quality concerns and I’m very much looking for feedback on this format: is it hearable? Does it bother you? Should I do more of these recaps?


    Please let me know via e-mail at m@ttias.be or on Twitter at @mattiasgeniar.

    #6.5: SysCast is taking a little break

    #6.5: SysCast is taking a little break

    I wish I didn’t have to bring this message, but I’m fairly certain you already noticed it: there hasn’t been a new SysCast podcast in a while.


    I’m taking a bit of a break to organise things, prepare better and overall bring a better show. But that takes time, and time is something I don’t have at the moment.


    The plan is to bring SysCast back in a few months. In the meantime, don’t unsubscribe just yet, keep the RSS feed going. In a few months, I hope to be back – full force.


    Meanwhile, if you’re craving more open source or linux news, have a look at the weekly newsletter called cron.weekly!

    #4: Curl, libcurl and the future of the web, with Daniel Stenberg

    If you’re a sysadmin or a developer, you’ve probably used curl before. Or some kind of project, like PHP, Python, Ruby, … that uses libcurl. You can thank Daniel Stenberg, creator and maintainer of curl, for that.


    In this episode I talk to Daniel about the history of curl and libcurl, we discuss the web and open source, Google’s Quic, LibreSSL vs OpenSSL and so much more. If you’re interested in ‘the web’, this episode is for you!
