The Planet MySQL has been abuzz with opinions for or against the acquisition of Sun (and in particular MySQL) by Oracle, but I do not have a strong opinion to chime in with in support of either groups. The reason is that I do not know anything about antitrust laws, which is the legal basis… Continue reading Oracle speculations

Orango.dk afgørelsen
[English summary: This discusses a recent legal decision that the domain orango.dk, which was used by one person for an email address since the year 2000, should be transfered to a newly started company with the same name. The decision has been appealed to the courts.] Som mange andre er jeg bekymret over den afgørelse,… Continue reading Orango.dk afgørelsen
MariaDB Buildbot configuration file published
I have now published the Buildbot configuration file that we use for our continuous integration tests in our Buildbot setup. Every push into main and development branches of MariaDB is built and tested on a range of platforms to catch and fix any problems early (and we also test MySQL releases before merging to easily… Continue reading MariaDB Buildbot configuration file published
Fixing a MariaDB package bug
One of the things that I am really happy about in MariaDB is that we have our releases available as apt (and yum for Centos) repositories. This is largely thanks to being able to build this on the OurDelta package build infrastructure (which again builds on things like the Debian packaging scripts for MySQL). Something… Continue reading Fixing a MariaDB package bug
(Almost) one year of MariaDB
Most of this year I have been working on the MariaDB project. So it is interesting to look back and see what has been achieved. For those that do not know, MariaDB is a project to create a community-oriented branch of the MySQL code base. We want MariaDB to be developed for the community, by… Continue reading (Almost) one year of MariaDB
Building MariaDB/MySQL with Buildbot and KVM
Testing and automation. These two are key to ensuring high quality of software releases. Ever since I worked briefly in the team at MySQL AB that is responsible for creating the binary (and source) packages of MySQL releases, I have had the vision of a fully automated release procedure. Whenever someone pushes a new commit… Continue reading Building MariaDB/MySQL with Buildbot and KVM
Valgrinding Drizzle
Like so many others, I got interested in the Drizzle project when it started. Some good ideas, lots of enthusiasm, and just pure GPL license, no “yes, we will take your work for free and sell proprietary licenses to it” SCA. I even started contributing some development, fixing a number of Valgrind-detected bugs in Drizzle.… Continue reading Valgrinding Drizzle
Learning Python
Among other things, these past few months I have been working on setting up Buildbot, including adding various enhancements and bug fixes that are needed to properly build and test the MariaDB and MySQL code base. Since Buildbot is written in Python, this means I have also had to learn Python. I am an old-time… Continue reading Learning Python
Network troubles, part 2
This is a followup to part 1 of the story, where I found that a hanging ftp transfer was caused by one of my network components not being able to transmit certain bit patterns. After getting on-site, I had the chance to move around cables to test each component in isolation. I was quite surprised… Continue reading Network troubles, part 2
Network troubles
As this story shows, the cause of a network problem is not always where youfirst suspect… So I just set up an ftp server on my home network for easy file transfer with some family members. Everything was working fine, except … occasionally, file transfers would just hang, for no apparent reasons. Logs did not… Continue reading Network troubles
