I’m starting to get quite a number of systems at home. Physical machines, virtual machines, desktop, laptops, smartphones, tablet,… most of them running Unix flavor (I still have a few Windows, but less and less
At home, we are 5: 2 parents, and 3 kids. Guess what ? All of them are willing to use a computer…
So I build up a little network that I’m trying to manage as simply as possible.
My challenge of the day: centralize logins and passwords to ensure consistent authentication across any device at home for everyone in the family.
When I started as Unix administrator, we were implementing Sun YP (yellow pages), which turned into NIS soon after.
I was looking for something even more flexible and more “in-line” with today usage of authentication…
This is how I came to look at LDAP (OpenLDAP)

I don’t know why, but Ubuntu packages for SIPE keep being defined without Audio/Video support…
If you want to get things working, you need to compile it yourself.
I already did it for Ubuntu 10.04 in article Pidgin & SIPE latest versions on Ubuntu 10.04.
Things are even simpler on Ubuntu 12.04.

As many of you, I’ve been using Google Calendar features for a long time. But that was not completely satisfying, from a pure “opensource” and intellectual property perspective…
I was also looking for a way to synchronize my various Thunderbird installations (my wife and I are both using several calendars and several address books…) across all devices we have at home/work (Linux, Windows, smartphones,…).
Yesterday, thanks to a colleague (another geek ? Check his website: ezIX), I found the answer. I decided to setup my own server for Calendar and for Address books.
This is DAViCal.

As you know, I have several systems running at home (physical and virtual machines).
I was looking for a way to “see” quickly any bottleneck, or any unusual activity on those systems from my laptop.
My first reaction was to go for a gnome-like system monitor (gnome-system-monitor).
Despite all criticisms I could read, it was showing me all necessary information, especially real-time graphs for CPU, Memory, and Network.
But when I launched them remotely (through an SSH session, and with the appropriate DISPLAY forwarding option), it showed clearly that it was consuming around 4Mb/s of Network bandwidth just to display… itself !
So, I googled a little bit, and I rediscovered a tool I used to install a long time ago : gkrellm

I wanted to improve some PERL script files, so I turned to a VIM plugin.
But it can quickly become complex to manage all those plugins inside VIM.
So I found an interesting page on a french blog: IT Wars (direct link to the article).
It was about installing Vundle
