Testing/Unstable sources The testing and unstable repositories of Debian provide with a higher version of software applications than what is present in the stable repository. Note that these names are actually aliases such that the stable repository points to the current Debian stable release and the Testing repository is what is going to be part of the next Debian stable release. So at the time of this post, Wheezy 7.x is the Stable release and...
The focus of this article is to select the finest shell scripting books which are available to download for free. Many of the books featured here can also be freely distributed. So get reading, learning and sharing.
Fonts In this post I am going to show you how to optimize font rendering on Linux Mint to get the best looking fonts. Linux Mint uses the Sans font by default on the desktop, that do not look that very nice on lcd monitors. So we shall do some tweaks to get great looking fonts on the desktop. The tweaks involve the following changes 1. Use Droid fonts on desktop 2. Use Noto fonts...
"The Linux Kernel 3.15 is now available for the users", announced Linus Torvalds. Just check what Linus wrote on the mailing list:
So I ended up doing an rc8 because I was a bit worried about some
last-minute dcache fixes, but it turns out that nobody seemed to even
notice those. We did have other issues during the week, though, so it
was just as well. The futex fixes and cleanups may stand out, but as
usual there's various other random fixes since rc8 in there too:
mainly drivers (drm, networking, sound, usb etc), networking,
scheduling and perf tooling.
But it's all been fairly small and quiet, which *may* of course be due
to the fact that last week was also the first week of the merge window
for 3.16. That might have distracted some developers. I'm not entirely
convinced I liked the overlap, but it seemed to work ok, and unless
people scream really loudly ("Please don't _ever_ do that again") and
give good reasons for doing so, I might end up doing that overlapping
merge window in the future too if it ends up helping out with some
particular timing issue.....

RSync or Remote Sync is the Linux command usually used for backup of files/directories and synchronizing them locally or remotely in an efficient way. One of the reasons of why RSync is preferred over all other alternatives is the speed of operation, RSync copies the chunk of data to other location at a significantly faster rate. This is because, whenever Rsync is executed for the very first occasion, it transfers all the data from source to the destination. On the next turn, it would just copy the files/directories whose contents are changed.
Another plus point of using this utility is, as it makes use of SSH protocol to encrypt the data to be replicated, so it is much more secure and trustworthy. One more advantage of using Rsync is, as it performs compression of the data at source end and decompresses it at the destination, the bandwidth used during the sync operation will be considerably less. Also, the file permissions, their user/group information and the timestamps is/can be preserved.
rsync [OPTIONS] SOURCE DESTINATION
-v : indicates Verbose mode which provides detailed information.
-r : indicates Recursive operation, timestamps and file permissions are not preserved
-a : indicates Archive mode,timestamps and file permissions are preserved
-z : indicates Compression, it compresses the data before it is transferred to destination.
-h : indicates Human Readable output format.

GeForce GTX TITAN Z GeForce GT 740 GeForce 830M GeForce 840M GeForce 845M GeForce GTX 850M
- Fixed a bug that caused X to crash when querying clock offsets for non-existent performance levels.
- Fixed a performance regression when running KDE with desktop effects using the OpenGL compositing backend.
- Fixed a bug that caused duplicate entries to appear in some dropdown menus in the "Application Profiles" page of nvidia-settings.
- Fixed a regression that could cause OpenGL rendering corruption on X screens with 30 bit per pixel color.
- Fixed a bug causing mode validation to fail for 4K resolutions over HDMI in certain situations.
- Added nvidia-settings command line controls for over- and under-clocking attributes. Please see the nvidia-settings(1) manual page for more details.
- Fixed several cosmetic issues in the clock control user interface of nvidia-settings.
- Added support for the GLX_EXT_stereo_tree extension. For more details, see the extension specification:http://www.opengl.org/registry/specs/EXT/glx_stereo_tree.txt

There is no denying the fact that Raspberry Pi has helped raise awareness of the possibilities for not only small but also inexpensive computers. But it's not powerful enough to do some CPU-heavy work, while faster options are emerging for users attracted to such board-like devices.
Giayee P105 Quard-Core ARM Ubuntu/Android Mini PC is just a powerful alternative.
Giayee P105 is based on a Quad core 1.6GHz Rockchip RK3188 SoC with integrated GPU （quad Mali-400）, enabling the device to run as a server (email, file, web) and also as a media center. Although Raspberry Pi can do these things also but Giayee P103C is faster. Besides, Giayee P103C can support high-end features such as 1080P video.
Compared with Raspberry Pi's one HDMI port, Giayee P103C supports VGA port, with 16 or 32bpp color depth, can be set up to 1920x1080 definition. The Giayee P105's three USB ports also gives it a bit more breathing room, relative to the one on BeagleBone Black.
There are two configurations depending on which CPU ,how much RAM and on-board flash storage you want. The less expensive Giayee P105 goes for $49 and has Rockchip RK3168 Dual core ARM Cortex A9 1.2GHz CPU, 1GB of RAM, 8GB of flash.By comparation the BeagleBone Black revision C has a single core ARM with 1GB of RAM and 4GB of flash and is offered at $55.
Giayee P105 will blow your doors off with high-performance specs, but it will not blow all the cash in your wallet. If you want a small low-powered, low-cost but powerful machine Giayee P105 might be just what you are looking for. Even if you are happy with your current device, this would make a great gift or perhaps a great backup device.
In South Africa, President Zuma recently signed a Privacy Protection Act into law. Various countries have similar laws in place.
Section 11 of said Act makes it a criminal offence to divulge/make known any personal details, contact information, etc., by any person to a third party. It seems a bit drastic but service providers, retailers, even banks have been selling contact details without consent.
This leaves one in a position where you may end up with a criminal record if you have been using cloud services to synchronize contacts, calendars, tasks, etc., via services such as Google and it gets leaked from there. The recent 145 million exposed accounts at eBay comes to mind.
In a criminal court, the state prosecutor may argue that the "reasonable man" should have foreseen such leaks, based upon the history of successful hacking attempts. It could be argued that the user should have refrained from using cloud services.
The sad thing is that, especially for Linux users, there currently is no local sync alternative, except for those who have the resources to run a server with something like ownCloud. Most users simply have no options as device manufacturers are adamant about pushing everything through the cloud.
I stand corrected on this, but I am almost 100% sure that a legal advisor from New Zealand or Australia voiced a similar concern. It is my hope that someone really develops a user-friendly (read: newbie) solution that can be easily installed and configured, at least for Android devices as this is used by the majority.
Webmin, an open-source tool written in Perl, is a web-based interface used for Linux system administration purposes. Webmin helps the users in user accounts management, disk quota management and file configurations. Not only this, with Webmin, ont can easily manage services like Apache server, MySQL, PHP and file sharing, to name a few. Being a web-based application, it uses TCP port 10000for handling the communication part through a web browser.
This article will guide you to install the latest version on the said application - Webmin 1.690 in your Ubuntu/Linux Mint Systems (or Debian based systems I should say). Before that, make sure that you have installed LAMP server in your system. If you do not know how to do that, please refer to our article: LAMP Server- Installation and Configuration in Linux
