This is an interesting article by Paolo Rotolo, it’s a comparison of MIR (in the Xmir version that will be present on Ubuntu 13.10) and the current Xorg.

After the announcement of Canonical on Mir, which will be included as a default display server in Ubuntu 13.10, I decided to do some tests (benchmark, in the jargon), to see whether the performances of Mir are comparable to those of the good old X.org (the daemons currently present on Ubuntu), as promised by Mark Shuttleworth on his blog.

All benchmarks were performed with the suite “Phoronix Test” on Ubuntu 13.10 (Saucy Salamander).

I’ve done all the test run on an hardware with low-medium specs (especially the video card), because with a more powerful PC, the differences between X.org and Mir would have been less relevant.

I am one person who has been fascinated by the virtualization. The idea that software can be able to take a single machine and divide it up to act and feel like several independent systems has never ceased to amaze me. The geniuses that came up with virtualization environments must be some really bright minded individuals.

Well, I have particularly been impressed by the way it can be able to simulate an entire machine with that has all the required hardware such as memory, processors, networking and all the resources user can wish for.

I have a list of some of the virtualization technologies that I have been privileged to try out. Do not worry, I am not exactly the tech junkie that most IT enthusiast are so everything you get from me is nothing short of simple observations without really going into the deep technical stuff.

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.

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.

Article from Tcat Houser editor-in-chief of TRCBNews.com that recently ignited some fire with 2 articles:
OpenOffice versus LibreOffice versus The World and The Biggest Failure in Open Source Is…

Some of the Linux faithful will look at this and say: “There he goes again, bashing open-source. He’s just a Microsoft shill.” They will use the fact I am an MCSE as ‘proof’ of their opinion.

Version 4.0 of LOO still suffers from the issue of cross file compatibility to Microsoft Office. However, the good news is the pain is less than ever before and we now get the ability to open Visio and Publisher files! Personally, I have not used either of these Microsoft programs in years so I cannot attest to how well they are handled.

Beyond my own daily use of LOO I have read in depth every review I could find on the Internet. My honest summary is they are far more negative than my feelings. Yes I must agree with everyone else that the most lacking area is complex documents not playing nice with MS Office. The second most cited shortcoming is the relatively confusing menus. I cannot really disagree there either. And there is always two sides to the coin. LOO’s brightside is shinier than ever. Less noticed is how much this version has pulled away to lead over Apache Open Office (AOO) formally known as Open Office Organization (OOO).
More about that later.
