I’ve received an announcement from Jean-Michel Philippe and I gladly publish it:

The whole team is very glad to inform you that DoudouLinux 2.0 Hyperborea is now officially out .

After 2 years of development, this new major version is providing many great new features with fully redesigned advanced activities, new graphics, new applications, a new installer, etc. Available in 43 languages, this release is nearly occurring 3 years after the birth of our project in 2010, which shows the interest our project has gained all around the world.

As usual you can give it a try from:

http://download.doudoulinux.org/

But DoudouLinux is not just a CD/DVD of educative stuffs for children.
DoudouLinux is now a vast project on its own. We have published with version 2.0 a manifesto that defines the philosophy and the ethics of our project: we want our children be able to fully master the digital world they are going to live in, instead of undergoing it.

As a result we now feel very concerned about user privacy, especially when it comes to children.

Let’s see some detail of this nice project

Sometimes it’s useful to do a step back and think at the way you are doing your daily tasks and in general how you approach your work, if you are interested in this topic I suggest also the great book “Time management for system administrator

This was written by Jennifer Davis and first published on http://sysadvent.blogspot.it/

For most of us, the end of year brings performance appraisals and reflection on the year’s setbacks and accomplishments both professional and personal. In the glass bowl of life, I ask myself if I’ve made a difference, earned respect, have I grown from where I started the year? Technology has brought us innovation to hack our lives and measure our personal success through metrics. For example measuring sleep, weight, and activity. For example, I can see how much I slept, how fast I biked to work this morning, how often I biked, and the steps forward (or back) towards my goals. There is a dearth in tools available to measure personal work growth and effectiveness.

Being an effective system administrator requires an ability to do several (seemingly obvious but often rather fraught) things: To break down projects into actions that we understand as a part, as a whole, and can manage in a discrete period of time; explaining this roadmap to other teams; and successfully keeping implementation on schedule while being flexible enough to handle any issues that arise. The job descriptions and responsibilities of system administrators can vary greatly in scope and the corresponding degrees of difficulty and creativity necessary to succeed. Since “system administrator” alone can sometimes function as a vague catch-all for such a diversity of tasks and functions we use a variety of sometimes unwieldy names to better specify our roles and focus. Regardless of title there is a great deal of commonality in how teams we work for/with view us and depend upon our knowledge and skills. In some cases it’s a bit like being a member of a symphony in which the strings, the brass, and the wind sections cannot agree upon the tempo or even what piece to play.

At a team level, management has a vision of what the team should be doing and how it should be working. Often our work is considered a cost center, something that doesn’t produce a direct profit and is generally first in line for cuts. Management becomes focused on the bottom line to the detriment of building a strong team and an encompassing vision. Teams are put in the unfortunate position of competing for finite resources. For better or worse, the team that “markets” itself best generally comes out ahead.

Sometime it happen that the command df and the command du report different results such as:

df -h /tmp
Filesystem            Size  Used Avail Use% Mounted on
/dev/vzfs             16G   12G   4G  75%  /tmp

While a du command show somethign different such as:

du -hs /tmp/
10G	/tmp/

There are usually different reason when this happen.

Today I want to do a roundup of the available text editor for our Linux computer, in particular I’ll take a look at the graphical text editor, so no vi, emacs, nano or joe today.

I’ll post what are in my opinion the pro and the cons of some of the text editor I’ve used in my day by day works, I’m not a programmer but sometimes I’ve to write some shell script or php functions and these software can really help you in these activity.

So let’s take a look at Gedit, Geany, Sublime text and Jedit
Some of these could be classified as IDE, but in general I’ve used them to just do some small text works, for this reason they are present in this article.

Sometimes it’s useful to write a bash script that do something like “Do this job, if it’s still running after XX second kill it”, how to implement this in a normal bash environment ?

Nothing simpler: Use the timeout shell command to achieve this.
From its info page:

timeout runs the given COMMAND and kills it if it is still running after the specified time interval

Let’s see how to use it.
