#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 email@example.com or on Twitter at @mattiasgeniar. Shownotes * Config Management Camp * Kubernetes * Next gen config management: mgmt * Digging into Kubernetes with Sysdig

#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!

#1: Matt Holt, creator of Caddy webserver
(Note: audio quality isn’t super great, I’ll get that fixed for episode #2) Exciting! This is the very first episode of the SysCast podcast! I’m very happy to have Matt Holt as my first guest, who created the Caddy webserver. We talk about the Caddy project, the Go language and community, the unique benefits of Caddy and its Caddyfile, dealing with Pull Requests and so much more. A couple of lessons learned on my part: * stereo recording is useless, everything should be mono (I now merged stereo to mono, but it came at a loss of audio quality) * I need to tweak my own recording settings, that’s obvious (it’s a good thing Matt’s voice is clearer than mine) Shownotes * Write a review in iTunes! * @mholt6: Matt on Twitter * caddyserver.com: the webserver * Server Side Push in HTTP/2 (benchmarked) * Gogs: git repository hosting written in Go * Laravel Valet: self-hosting in development for Laravel projects, powered by Caddy
