1. Nomad ARM cluster

    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 …

  2. Archlinux ARM pi zero cups network print server


    Probably like many amongst us the time of the Christmas holidays is perfect to get some IT related stuff back on track. I used to have a print server setup which got broken over time and I didn't found the energy to invest time into fixing it. But the pressure became higher and higher. 111 From both my wife and daughter, especially during the holidays where the wife want to use it to print out tickets and the daughter want to print out color plates..

    So during one of the evenings I pulled myself together and installed ArchLinux ARM …

  3. wireless bond archlinux arm

    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 …

  4. Raspberry pi setup

    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 …

  5. Octoprint

    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 …
