On Linux, Cairo Clock is a very popular clock that many users love. Numerous developers have made a variety of looks for this clock called themes or skins. This article will provide information on making, downloading, installing, activating, deleting, and sharing Cairo Clock themes.

The Dave and Gunnar Show is a new podcast series talking about government, open source, and a sprinkling of Red Hat projects. I recently discovered it and thought the opensource.com audience might enjoy it too. What do you think? Episode 10, Go Ugly Early particulary struck me. Give it a listen:

Version 19 beta: Still alive or dead on arrival? Review The Schrödinger's cat thought experiment, devised by Erwin Schrödinger in 1935, pits the theory of quantum superposition against what we observe to be true.…

Gedit is a popular text editor that many users use to write notes, create BASH and Python scripts, view configuration files, etc. Sometimes, users may want to change the way Gedit displays text. This is very useful to programmers. Gedit gives specific colors to the variables and another color for the commands. Many parts of the programming syntax has a special color. This programmer can immediately identify parts of the code by seeing the color. However, what if the programmer is color-blind or does not like the way some of the colors look? Thankfully, a simple XML file can instruct Gedit how to display programming syntaxes and plain text. This single XML file, that averages around 10kB, is called a Style Scheme or a Syntax File.

And actually, some of the most popular are Free Software. In the just-released Fedora 19 beta, three of those are available for installation. All you need to do is type yum install and you are set to go, provided there is a 3D printer connected to your computer.

Over the past few years, a handful of different encrypted messaging systems have cropped up and gained prominence, notably Cryptocat and the OTR specification. Now a newcomer to the scene proposes a different way of thinking about encrypted communication, one that borrows from its more well-known older brother, BitCoin.

A project has been started that intends to recreate BitCoin’s decentralized P2P model for seamless message encryption and transmission. BitMessage was started by Jonathan Warr en late last year and has now made it up to version 0.2.4. One of the most prominent strengths of the BitMessage system is how it enforces anonymity. Similar to how BitCoin allows one to send money to anonymous recipients without advertising metadata to others, BitMessage communicates via simple addresses generated from public keys, which need not be tied to a specific user’s identity.

Raspberry Pi hackers now have a new OS option built by the The Seneca Centre for Development of Open Technology (CDOT). Pidora is a Fedora remix optimized specifically for the Raspberry Pi based on a brand-new build of Fedora for the ARMv6 architecture."The Pidora build was performed at Seneca's Centre for Development of Open Technology based on our experience operating the Fedora ARMv5tel/armv7hl build farm over the past three years," said Chris Tyler, Industrial Research Chair at the CDOT.

Spacewalk is an open source configuration management tool sponsored by Red Hat. Spacewalk is alternate of Redhat network satellite server on Centos / Fedora / Scientific Linux. Spacewalk is the upstream project for the source of Red Hat Network Satellite.

Linux crept up slightly in the EE Times 2013 Embedded Market Study,” representing 34 percent of current projects while Android showed the greatest growth, jumping to 16 percent, for a total of 50 percent for Linux-based platforms. Meanwhile, ARM processors continue to attract more embedded developers.The results should be seen as a general, but imperfect, guide to trends in the immensely broad and varied world of embedded development.

Here's a very quick and terse update on where we are with hardware for the long-awaited (by me if no-one else ;) Vivaldi tablet hardware: SoC PCBs: done; Mer: booting'; Plasma Active: starts; X11: running, still toying with opengl; Still waiting on a pair of drivers; Casework being tweaked to smooth out some rough edges; Screen components: sourced and ready. Which means we are finally, after months of unexpected delays (it's amazing how many different ways a PCB can be done in not-quite-the-right way ...) (where) we have production designs in the box. We're not quite at the point where we can send them shuffling of the production line into little boxes to send to you, but we actually have a device that works and whose design we own so that our ability to deliver is in our own hands.

MediaTek announced its first quad-core system-on-chip aimed at tablets. The MT8125 integrates four 1.5GHz Cortex-A7 cores with Imagination Technologies’ PowerVR Series5XT GPU, enabling 1080p video recording, 1920 x 1200 resolution, and a 13-megapixel camera, and offers integrated 3G HSPA+, 2G EDGE, and WiFi communications.

'Let's focus on our own excellence, not someone else's product'. Ubuntu headman and part-time astronaut Mark Shuttleworth has declared victory over Microsoft's domination of the PC industry, noting that the competitive landscape today is far different from what it was when Ubuntu launched in 2004.…

During development of Plasma Active, I resurrected an idea that a couple of us had tinkered with a year or two earlier: creating an open content store. We have ended up creating something fairly different than what is available out there right now and none of these differences are accidental. Before launching into a description of what this system is and how it works, I thought I'd start with a short blog entry describing the things we were not happy with in the state of the art of app stores.

Ubuntu’s SABDFL (“self-appointed benevolent dictator for life,” as he’s known) Mark Shuttleworth just added comment No. 1834 to Ubuntu’s Bug No. 1 — “Microsoft Has a Majority Market Share” — and closed the bug.

This is the default desktop. According to sources from deep inside the Linux Mint team, this is the best desktop background ever designed by man, or woman. That’s why it will be the default desktop on all releases of Linux Mint or Linux Mint Debian from now till Thy Kingdom Come.

SolydK is pretty amazing, and so is SolydX. Both are recommendable to newbies.

In this tutorial i will show you how to install local repository in Ubuntu 13.04 server in two methods. If you use external hdd then it will your portable repository. You can use it in multiple locations other than your LAN. Both are easy to install and configure, finally pick one of them for your requirement.

The choices offered on the poll were Symbian, Ubuntu, Android, Windows, Firefox OS, iOS, MeeGo, Mer, Blackberry 10 and Other. Voters were allowed to choose only one operating system and those choosing Other were provided a text box to enter their choice. Voters were blocked from taking the poll multiple times by IP address. A total of 238 people took this poll.

Dietrich Schmitz of linuxadvocates.com asked the question about Canonical's financial solvency. I look into the matter to see if there's more to the story.

In this post, I will try to provide enough resources for you to get started on mobile application development using QT Meta Language (QML). Although QML is not Ubuntu specific package, there will be some libraries and convention used in this tutorial that is specific for Ubuntu. However, you could easily use resources mentioned in this post to port your application to the platform of your choice.
