This is a follow up to the blogpost from a year ago. I’ve went back and tested the InfinityBook 14” Pro V4 with OpenBSD-current (as of 2019-09-13). Last year, hibernate as well as Suspend/Resume did not work properly, this is now fixed and works like a charm. A complete dmesg can be found here. ...

Vacation time is time to clean things up and as such I can now release 0.2.0 of gridscale-check. Binaries can be downloaded from the releases page. Since gridscale has released the stable version of gsclient-go - our go SDK it was time to move gridscale-check from using libretto to gsclient-go. ...

Last year I’ve added preliminary support to libretto. Back then the libretto project already seemed a bit abandonded. Now it is gone. Since gridscale has released a go sdk it does not make sense to keep the fork of libretto around - especially not, since I’ve updated gridscale-check to work with ...

Since I recently changed my lastname to include our family name, moving from Kronlage to Kronlage-Dammers, it was time for a new gpg key. rsa4096/824CE0F0 2019-09-07 [SC] [expires: 2023-09-07] Key fingerprint = 2082 651E 5104 F989 4D18 BB2E 0B26 6738 824C E0F0 The new key is available from ke...

TL;DR The InfinityBook 14” v2 is a fanless 14” notebook. It is an excellent choice for running OpenBSD - but order it with the supported wireless card (see below.). I’ve set it up in a dual-boot configuration so that I can switch between Linux and OpenBSD - mainly to spot differences in the d...

I’ll be publishing a few articles around the german hardware vendor TUXEDO Computers shortly. Before I proceed with those here a short disclaimer: I’m not affiliated with TUXEDO Computers in any ways nor do I have any financial benefits from talking and blogging about them. However TUXEDO Compu...

It’s been a quite year - at least to the observer from the intertubes. :) Let’s quickly recap last year. After a four months of a work-break (first time in 20 years - really something I can recommend, but I will likely come back to that subject in a different post), I started at gridscale in Octo...

The past week was a conference week for me. It started with the 2018 edition of OpenRheinRuhr, continued with the 13th Open Source Monitoring Conference (for me it was the fourth one I attended, yet the first one as a speaker) and the third one was the Open Source Day of the OSB Alliance. OpenRh...

(Disclaimer: I work at gridscale.) OpenBSD 6.4 with nested virtualization at gridscale Since OpenBSD 6.4 was released the other day I wanted to give it a shot on our platform. Especially since we offer nested virtualization support (as a beta) I wanted to see how well the vmm(4) subsystem works...

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.
