A year and a half ago I did an entry entitled "Overview and Explanation of Linux Desktop Environments". Anyone that is in the technology field (or knows even a little bit about it) knows that 18 months is a like a life time in the world of tech. Today I would like to re-cap my previous post with a few additions that have been added in recent months and mention a few desktops I missed last time.

(Sacramento, CA, USA: December 21, 2011) The Linux Professional Institute (LPI), the world's premier Linux certification organization (http://www.lpi.org), announced promotional exam labs for their Linux Professional Institute Certification (LPIC) at the Southern California Linux Expo (SCALE 10X -- Hilton Airport Hotel, Los Angeles, California: January 20-22, 2012: https://www.socallinuxexpo.org/scale10x/events/lpi-exam-cert...)

Unix based operating systems like Linux offer a unique approach to join two discrete commands, and generate a new command using the concept of pipe(lines). For example, consider command1|command2. Here, whatever output is generated by the first command becomes the standard input for the second command. We can develop more and more complex Unix command sequences by joining many commands while maintaining input output relationships.

This article is a bit different from my usual column in two ways. First, it's starting with a hardware and software combo—something I've not done before. Second, the projects are linked to each other and come recommended to me by Perth LUG member, Simon Newton.

Change is the one constant in the IT business these days. Everywhere you look the world is shifting, and in August alone this year we saw a bevy of surprising announcements from some of the most trusted technology brands.

The main feature or duty of a proxy server could be a gateway that receives HTTP requests from clients and forwards the request to the destination and relays the answer back to the requestor. Squid is most popular open-source software that brings this to us. It also has some excellent features for doing something else such as web access controlling, bandwidth controlling, restriction policies, and content caching and filtering. Actually people install SQUID to pursuit 2 goals: first reduce the bandwidth charges by content caching and second for restricting access to particular contents. The following guide explains advantages of using Squid and will show you how to install, configure, control, and maintain the Squid Proxy Server on RHEL5 and CentOS Linux.

Best GNOME Shell extensions that can be easily installed through gnome extensions site.

Clement Lefebvre, the Linux Mint founder, has started working on a GNOME Shell fork called Cinnamon, which tries to offer a layout similar to GNOME 2, with emphasis on "making users feel at home and providing them with an easy to use and comfortable desktop experience":

The Document Foundation proudly announced a few minutes the immediate availability for download and testing of the first Beta release of the upcoming LibreOffice 3.5 open source office suite.

The universe that contains GNU/Linux and Free Software rarely slows down for simple things such as holidays. This week proved to be no exception. Rex talks about WebOS being open-sourced, The FCC, and Red Hat's record breaking quarter.

LXer Feature: 21-Dec-2011

Unity is more natural and user friendly to me than anything else..finally. I have not booted windows for 4 months. This is not one of those hate article or Windows vs Linux article, so if you have such intentions please feel free to escape this article presently.

The government of the State of Rio de Janeiro, the second largest state in Brazil, passed a new law which mandates public entities and companies in Rio de Janeiro to give preference to open document formats, in particular ODF.

Adobe Corporation, these are two words that every contemporary photographer, architect, artist and designer knows well.  And it would not be an understatement to describe Adobe’s suite of software applications as ubiquitous to everyday 21st century life.

If after reading about the recent Nouveau DRM improvements, you were hoping the kernel driver updates fixed-up the situation for the Fermi "NVD0" graphics processors, you are sadly mistaken: it is still a busted mess.

Puppy is a lightweight distribution designed for old computers, and can be installed in about half a dozen ways, including CD/DVD, USB stick, ZIP drive and via hard drive. It runs entirely in memory, and is persistent by means of a persistence file which you can place in any location you desire, including your hard drive, a USB stick, or even on the disk you booted from, although this is still an experimental feature which unfortunately I couldn’t test.

Demand for embedded programming is growing like crazy, so anyone looking for some job security might consider becoming an ace embedded programmer. It helps to have some programming experience, but even raw beginners can get started inexpensively and learn on their own. One of the friendliest introductions to embedded coding is Arduino. Arduino is a popular open embedded hardware and software platform with hundreds of howtos and projects to try out. Today we review the basics of both electronics and Arduino coding in a fun holiday project, Singing Holiday Snowman.

This past months Linux communities have seen much hate toward new GUIs. Aesthetics aside; their newness together with their widespread use is a big problem, but they also bought a change, something we did not see before. Refreshing, even.

These are interesting times for the Linux desktop. The often-overlooked area of the Linux ecosystem is now the centre of attention and, while some users have welcomed the changes, others have reacted in true community style: ranting and raging, threatening to abandon ship or, when all else fails, demanding a fork.

Those who were worrying that Microsoft's incompetent Bing might become the default search engine of Mozilla's Firefox can sit back and relax. Mozilla and Google have renewed their deal. Google accounts for 84% of Mozilla's earnings, which sponsors project such as Firefox and Thunderbird.
