would like to share my recent observations between Fedora 21 ( just released ) vs UBuntu 14.10.
Configuration of my machine :: SONY VAIO VPCEB1E03, core i3 ( 1st generation), 8GB ram, 320gb HDD,
Background :: Just one week back installed Ubuntu 14.0 on my laptop by erasing windows 7. Impressed with the look and feel of Ubuntu, within few minutes able to use it. Today installed fedora 21 official release on the same m/c by erasing Ubuntu 14.10. My observations are like the following. Just trying to settle down whether i have to go with UBuntu way or fedora way (?) . Lets see what i have decided!!
Performance / User experience ( UBuntu 14.10 vs Fedora 21-5 official release )
Looks impressive, Terminal window is beautifully coloured, graphics are good, heavy weight icons Seems, everything is OK, graphics drivers are installed no issues. But, I am facing few problems, like fan control always my FAN is running very fast and making noise, RAM is eaten up around 1.8 to 2.2 GB. Started rhythm box music player, after playing sometime closed it. Executed top command, and it is showing still music player is running and utilizing CPU (??), I have to manually shut down the player. Now, coming to application search box , when I type from keyboard my letters are being displayed very slowly, applications display is very very slow at this moment, my FAN makes so much noise. Disabled web searching options in the settings, still i have same issues. Software updates are installed without any issues. GCC 4.9.1 is working fine. kernel 3.16.x
Fedora 21-5 ( Official release ) ::
Instsalled, compared to Ubuntu installation seems this is fast. everything is fine. Now, repeated same actions from GNOME window manager. graphics drivers are installed no issues. surprisingly regarding FAN control, my fan is so silent and it is not making any noise, so so so quiet. RAM is around 780MB is eaten up when I opened firefox, rhythm box music player and few terminals. it was never above 1 GB.. thats impressive(same applications were opened with Ubuntu 14.10 also, it was RAM hungry 1.8 GB to 2.2GB). applications are closed and immediately disappeared from my TOP command menu. The surprising and I like very much is application search box.... Unlike in UBuntu Unity desktop search option, the Fedora 21 search is very fast , display is very fast, text input is very fast, i have tested really half an hour and seems, everything is awesome. FAN is not making any noise very quiet. I havent even disabled web searching. Software upadtes are installed without any issue. Well, one awkward situation with fedora 21 is without using GNOME TWEAK TOOL, i cannot get my minimize and maximize buttons in terminal. Fedora terminal windows are good, but compared to Ubuntu terminals they are less attractivre. GCC 4.9.2 is working fine. Kernel is 3.17.x
I am a computer engineering graduate and software architect. I thought i will stick to UBuntu because of its impressive looks. But, due its resource hungry nature and slow response times from desktop point of view, I think i will stick to FEDORA 21. btw, I have two more laptops which run REDHAT ENTERPRISE LINUX 7.0 and SUSE ENTERPRISE LINUX 12.0 commercial versions, using core i7 and core i5 respectively . RHEL 7.0 is more impressive from user experience point of view compared to all others.
UBuntu applications and Fedora 21 applications are almost all are same. Same packages, same utilities, i think I can do everything with both the versions from LINUX POINT OF VIEW.
If UBUntu improves its response times with its window manager Unity , then it will become a great desktop compared to other versions. Seems, UBuntu team is concentrating only on good looks without bothering about response times. Their team should concentrate on improving response times.
For the moment next 6 months, i will stick with fedora 21 only, Lets see what UBuntu 15.04 will come up with an answer to Fedora 21.

The center for international and intercultural communication (ZiiK) at the Technical University Berlin (TU) is dedicated to offering students from developing countries long-term perspectives focussing hereby on sustainable help in information technology.
Since 2002, Dr. Nazir Peroz, born in Afghanistan and Director of the Ziik, supervised the setup of new IT centers in five Afghan universities with the use of open source software. â€śFrom the beginning, our aim was always to create something that will continue to help Afghanistan in the long term as well, something which opens up perspectives for the future for the nation, and offers the people hopeâ€ť, explained Peroz. â€śThe IT sector is ideal for achieving these goals because it is indispensable for modern economy on the one hand and requires lower investments in hardware than other branches of trade on the other.â€ť
When the team arrived in Kabul first in 2002, the situation was dreadful. After decades of war and the tyranny of the Taliban, there was not much of the academic education system left. In the whole of the capitalâ€™s college there were just a handful of old computers, some of which didnâ€™t even work anymore. When establishing the computer centers, the Germano-Afghan project employed Open Source software right from the start. â€śNaturally, the license costs were the most important reason for choosing Open Source softwareâ€ť, said Daniel Tippmann, Project Planner and Coordinator at the ZiiK.
As to the operating system to use, the team wanted a system, which puts the Afghan staff in a position to perform all the necessary work with as little training as possible and if possible without our support. Over the years, the ZiiK team and its Afghan partners tried out numerous different operating systems, primarily different Linux distributions. The youngest of the computer centers, the IT Center Kandahar (ITCQ), was the first to set up all the servers on the basis of Univention Corporate Server (UCS), which proved to be the best for them in terms of ease of use, flexibility and scope of action due to its App Center, which offers the installation and integration of numerous other proven open source solutions. Until the end of 2015, the other four universities will follow and migrate completely to UCS.

The latest patch level release UCS 3.2-3 includes all errata updates and an update to Linux kernel version 3.10.11 which involves many bug fixes and improves the hardware support.
Special highlight is the new module "Active Directory Connection", which replaces the previous AD connector for mounting a UCS installation in an AD domain. UCS users can now not only migrate an existing Microsoft server system to UCS but also configure their UCS system as part of an existing AD domain, for example to use UCS as the platform for applications from independent third-party solutions via the Univention App Center. Further highlights are a completely revised system setup wizard, a backport of PHP 5.4.4 and improved replication between OpenLDAP and Samba 4.

What is Web signage? It's the future of signage aka DOOH. Powered by Linux.
Allow me to explain.
First generation sign - Static
An etching on a cave wall, to a flashing Neon sign. These are static signs usually fixed to a particular location. Their often cumbersome to replace, though are pretty simple and reliable.
Second generation sign - Digital
Using usually a standard TV screen, a series of images are displayed in rotation or a video is simply looped. Some televisions are capable of being programmed to become a sign, simply by inserting a USB stick. Most solutions sadly fail to provide a polished out of the box solution for this use case, requiring someone to setup the DVD player or re-configure the software on the "SMART TV", every single time that device is power cycled or fails. Awkward.
Even though most "SMART TV"s are powered by Linux, typically TV manufacturers provide no documentation or way to modify the existing software to stream line this relatively simple use case. Which is a shame.
This generation of signage is where we are mostly at the moment. Advertisers like this as they can convey "experiences" well with short clips, sometimes with an annoying sounded message, in rotation. They are usually easy to update, but often they are not for hours at a time, since most of them use a USB stick as their source which manually needs to be swapped out.
Third generation sign - Internet powered
There are many players in the "DOOH" industry vying for your custom, peddaling their own proprietary systems that lock customers onto their particular platform, e.g. BrightSign or Harris are leading examples.
You can recognise these locked in systems easily because they are not Web powered or confusingly embrace and extend the Web.
There are even "opensource" platforms to create signage content, but since they do not use Web standards to layout the content, they should be avoided, as they are effectively locking you into their format only they control.
Note that all you need to configure a proper Web signage operating system is a URL. So switching between Web signage players should be even easier than switching between Chrome & Firefox today.
There are a couple of major stumbling blocks to Web signage, the first being that many advertisers and "DOOH" content producers are really quite poor at creating and managing Web content with information.
The second is that the "Web sign" playback devices are typically clumsily put together boxes running a full screen browser, with no "polish".
I don't have quick solutions to offer for the first problem, though for the second problem, one solution is Webconverger Neon.
It runs Linux. It's opensource It supports a wide range of hardware. It's stable. It keeps the browser upto date, supporting the latest standards like the Web Video Text Tracks Format.
Furthermore Webconverger Neon is polished, if it fails in often hostile outdoor environments, such as a hardware issue of loss of connectivity, it defaults to a black screen. No silly network can't be found messages. No blue screens. No modal dialog boxes. And then network/hardware is restored, it lights back up as best it can as it's retrying in the background.
As for networked Web signage itself, information can be delivered as fast as a Web page takes to load. Images, videos and other HTML useful technologies such as caching can be used to deliver useful information. Just like your favourite Web application.
On Friday, July 18, Univention and Mandriva will demonstrate live how their solutions Univention Corporate Server (UCS) and Mandriva Pulse work perfectly together.
