as I already mentioned a few times before I have some hands on experiences with nomad. A couple of weeks ago I wrote about a local development setup based on nomad.

Since quite some time I do have a thinclient which is running some docker containers through a docker-compose file I use for personal stuff at home. But this thinclient is suffering from all the containers I'm trying to spin up. While over thinking this issue I did realize I have quite some raspberry pi's laying around and figured I could maybe set up a cluster for those containers.

Since …

for one of my projects, the sms-twitter wall setup, I configured a raspberry pi with 2 wireless network interfaces to connect through a hotspot enabled on an android device. I discovered on previous events that the wireless adapter failed on me from time to time. So I went to the internet to look if I could add a second interface and bond them together.

I found a lot of documentation on how to bond an active-backup strategy with a wired and a wireless interfaces but didn't found a setup with 2 wireless interfaces. After a while I figured out how …

A long time ago I was active in the local scouting group. To earn some money to keep our group in a healthy financial position we organized a so called vedettweekend. It's an event where people can have a beer, vedett obviously spin a dance, enjoy a spaghetti and have a good chat with your friends.

I always played with the idea of creating a social media wall on one of the projectors we rented for the event. But I never found/made time for it, until today.. My youngest brother is who's interests are overlapping with mine brought up …

As I already wrote about in the past I have a raspberry pi running at home. I do also have a VPS running somewhere on the interweb for an owncloud instance.

Being a sysadmin I wanted to know when my home devices become unreachable and when the owncloud instance is down. By mail in the first place if possible by sms message for free in the ideal world.

And guess what, I managed to reach the ideal world to monitor my instances. Over here I'll describe how I managed to do so.

Since I discovered the joy of linux servers over desktop distributions a few years ago I revived an old portable and promoted him to be my home server.

Connected him our router in the little storage room on a top shelf gathering dust I could test, configure, break (and pass sleep) a huge variety of open-source software.

Many of those adventures I also used to provide my blog with content. After a while I figured this setup isn't really needed to be powered on 24h a day 7 days a week. So I bought myself a raspberry pi which would …

At our office we have an ultimaker 2 installed, we have it now for some weeks and already printed out a bunch of stuff. It's cool to see, amazed by the technology.

Expect the manner to start a print job, you have to save your generated gcode files onto an SD card, stick it into the ultimaker and use the rather simple menu from the tiny display to start the print job.

The time of a print job is rather long depending on the object you want to print, so many times you got up and went seeing if everything …
