A Selection of Talks from FOSDEM 2016

It's that time of the year where I go to FOSDEM (Free and Open Source Software Developers' European Meeting). The keynotes and the maintracks are very good, with good presentations and contents.

It's very dificult to choose what talks to see, what talks to see later in video and what talks to loose. What I leave here is my selection of talks. This selection is representative of my tastes, not of the quality of the presentations. I will give links for material that is available now. I will do periodic updates when the new material is available: video or slides.

Preview of switchconf 0.0.14-2 in Debian

There was a long time since I published the last version of switchconf.

This time someone requested that I add support for systemd by adding a service file. This service file does not make switchconf depend on systemd. It will still work with svs init scripts.

As my knowledge of systemd is minimal, please review my changes.

To download use the following entries:

switchconf_0.0.14-2_wip4_all.deb

switchconf_0.0.14-2_wip4.debian.tar.xz

switchconf_0.0.14-2_wip4.dsc

switchconf_0.0.14-2_wip4_amd64.changes

Collect and keeps up to date the system information using sysinfoupdate

In 2005 I was looking for ways to auto collect information about a Linux server. The information was to be used in case of bare bones recovery. I didn't found a satisfactory program so I created one, sysinfoupdate. This program have been growing long this years and now is a system that helps to maintain a diary of a Linux Installation. The diary records all the important changes the sysadmin does to the system. This records can be used during recovery after a broken hardware or to detect what change may be causing a malfunction, for example.

It's use is very simple, create a diario directory in your home directory, for example /root/diario, and then run sysinfoupdate. Inside diario you will find a group files with textual information about your system. It works best if you run it as superuser and you keep track of the changes under a version control system, like subversion or git.

You can download the Debian package here or download the source from here.

A Selection of Talks from FOSDEM 2014.

It's that time of the year where I go to FOSDEM (Free and Open Source Software Developers' European Meeting). The keynotes and the maintracks are very good, with good presentations and contents.

It is a big conference and this year, is not an exception. With 445 speakers and 512 talks at 22 rooms in only two days. It's impossible to see all the presentations. This year all the rooms have a video camcorder.

It's very dificult to choose what talks to see, what talks to see later in video and what talks to loose. What I leave here is my selection of talks. This selection is representative of my tastes, not of the quality of the presentations. I will give links for material that is available now. I will do periodic updates when the new material is available: video or slides.
