Im Rahmen der Kielux 2018 hab ich einen “Vortrag” eingereicht der von vornerein als Panels ausgelegt war. Idee war, das Teilnehmer*innen jeweils zwei oder drei Ihrer liebsten Podcasts vorstellen. Dazu hatte ich auch im Vorfeld etwas Werbung gemacht und auf diesem Weg bereits netterweise, zb. vo...

Der Open Source Business Award (OSBAR) wird jedes Jahr von der OSB Alliance verliehen. An sich möchte ich aber schreiben: Wird jedes Jahr von uns verliehen. Ich bin ein recht aktives Mitglied der TF-OSBAR und freue mich, das wir jedes Jahr aufs Neue von der OSB Alliance aus die Möglichkeit bekomm...

Disclaimer: I came across the Tuxedo Computers InfinityBook last year at the Open! Conference where Tuxedo had a small booth. Previously they came to my attention since they’re a member of the OSB Alliance on whose board I’m a member. Furthermore Tuxedo Computers are a sponsor of the OSBAR whic...

Taken the list of features from part 1 of this series, let’s go to select how we can achieve what: local users a good candidate seems to be: pstore, this is because we will use postgresql in the main application anyways. The same author has released several libs that can be i...

A few weeks ago a good friend of mine and me had a discussion about the usefulness of frameworks and libraries mixed with the desire “to know how things work” and such build them yourself. For a certain application the userhandling was still one of the missing pieces and I suggested “why not use...

I wanted to give Ubuntu 18.04 a spin on my FreeBSD box and threw it into bhyve. There is a good tutorial for Ubuntu 16.04. Once I installed with that the vm got stuck in grub. The bhyve config file for an ubuntu 18.04 machine needs to have the following line for grub: grub_run_partition="2" F...

With the recent addition of the relations to the VM layer in the gridscale support for libretto, it’s now a matter of a few lines of code to check for certain criteria. See this blogpost on some notes on relations. Before we dive into the examples: gridscale-check lives at g.hazardous.org. Che...

Since most of the currently existing libretto drivers mainly do the provisioning I did the same thing for the first addition of gridscale support and concentrated on the provisioning of an instance. I now went back and started(!) to add support for retrieving for complete set of items. Gridscal...

Echtzeit jetzt? Im Folgenden gehe ich davon aus, das die grundsätzliche Idee ein interaktives Werkzeug zur internen Kommunikation keiner Diskussion bedarf. Nachdem Slack vor einigen Jahren sehr populär wurde und alle - die bis dato einen grossen Bogen um Jabber und irc gemacht haben - auf einmal...

Since I was fiddling with libretto and gridscale anyways and I had the urge to monitor wether or not there are always five snapshots of a certain storage with the youngest being two hours old at maximum, I came up with a small check command for icinga/nagios: gridscale-check Checking the number ...

A while ago I started on adding support for the german IaaS-provider gridscale to the golang library libretto. libretto is used to orchestrate various IaaS-solutions such as Azure, AWS, Google Cloud Platform, on-premise solutions such as OpenStack and others. For a complete list take a look at ...

Heute war die Veranstaltung, die ich gerne als Neujahrsempfang der Open Source Business Szene in Deutschland bezeichne, in Bremen: Der Univention Summit 2018. Das Motto - ich find es wirklich gut: Reclaim your identities. Dieser fand heute zum 10. Mal statt - ein Jubiläums-Summit. Dazu kann man...

imapsync is a well-known tool for migrating e-mail boxes from one server to another. I’ve been using imapsync for many years and over at bytemine it is our tool of choice for this job. Aside from general praise of imapsync, I want to show couple of nice options for archiving stuff. I use the pas...

I’ve been asked repeatedly to make my old OpenDarwin content available. Here it is: od_public_html I’ve left the OpenDarwin project in 2005.
