One of the big frustrations of writing a book is that while Microsoft Word can be used for creating and formatting a book, it’s a real pain in the neck for ordinary mortals to use it for that purpose. Hmm. What's up with that?

The feature of Ubuntu on phones that Mark Shuttleworth is talking up this weekend is... the bottom edge of the phone in Ubuntu.

Several security issues were fixed in the kernel.

Infinity Wars is a new breed of Trading Card Game, introducing beautifully animated cards and animated 3D battlefields.

ADL released a compact SBC based on Intel’s Atom E3800, featuring multiple GbE, SATA, and display ports, PCIe expansion, and extended temperature operation.

Several security issues were fixed in the kernel.

For much of the Linux operating system's history, patching a kernel has been a process that has typically involved downtime. In 2014, that's no longer the case as there are now at least three different efforts that all offer the promise of zero downtime kernel patching to Linux servers.

New sudo packages are available for Slackware 13.0, 13.1, and 13.37 to fix a security issue.

LinuxSecurity.com: The Tor network is in danger of being swamped by criminals abusing its anonymity to hide an underworld of parasitic botnets, malicious command and control and 'darknet' markets, according to research from Kaspersky Lab.

The scourge of the remote access trojan (RAT)—those predatory apps that use Web microphones and cameras to surreptitiously spy on victims—has formally entered the Android arena. Not only have researchers found a covert RAT briefly available for download in the official Google Play store, they have also detected a full-featured toolkit for sale in underground forums that could make it easy for other peeping Toms to do the same thing.

The specific RAT in Google Play was disguised as a legitimate app called Parental Control, according to Marc Rogers, principal security researcher at Lookout Mobile, a provider of antimalware software for Android phones. He doesn't know exactly how long it was available on Google servers, but he believes it wasn't long.

"This course will be free as a MOOC, and we're happy to donate it to increase the number of people who can access the material," she said. "There is huge, unmet demand for Linux expertise in the market, and this can start to help address that." -

Spine is a full-featured 2D skeletal animation for games with Linux support as standard. A good thing for developers working on Linux directly.

The following is how you can add the latest Bodhi desktop to your existing Ubuntu 14.04 install.

Personal Audio LLC has recently become one of the more well-known "patent trolls" due to its broad claims to owning basic podcasting technology. The company has filed lawsuits in East Texas, claiming that its patents on "episodic content" technology, which stem from founder Jim Logan's failed "Magazines on Tape" business, entitle it to royalties from podcasters large and small.

That got the company special attention from the Electronic Frontier Foundation, which crowdfunded a challenge to the Personal Audio patents. EFF asked donors to help raise $30,000 to file an "inter partes review" at the US Patent and Trademark Office. That goal was quickly surpassed, and EFF ultimately received about $80,000 from more than 1,300 donors upset about the "podcasting patent."

FortressCraft Evolved is a hard to describe game that takes a lot from Minecraft with a much more expansive building system.

One of the long-standing proclaimed benefits of Direct Rendering Manager (DRM) graphics drivers for the Linux kernel was that it would be possible to have "Blue Screen of Death"-like error messages in cases of kernel issues. That feature is now closer to being realized while also advancing another goal of disabling VT support within the Linux kernel.

The first Tropico game to ever grace out platform isn't far away, Tropico 5 now has a proper gameplay trailer and it's looking fantastic!

In today's open source roundup: Forget about running Windows applications via Wine in Chrome OS. Plus: Live the life of a roach in Steam for Linux, and take a free Introduction to Linux class.

IcedTea Web could be made to expose or alter sensitive information.

The latest bi-weekly development release of Wine is now available, but sadly it doesn't yet mainline the major Direct3D command stream work for improved performance nor has it moved much along with its Direct3D 10/11 work...

Several security issues were fixed in Tomcat.

Many of us grew up with LOGO, the kid-friendly programming language that guided a little turtle around a screen. Yes, it was simplistic. Yes, it taught only the very basics of programming concepts, but it also inspired an entire generation of programmers. The applications you run every day were written by people who steered a digital turtle around a screen in third grade.

Phil Cummings says network firewalls will continue to be a critical piece of Health Information Technology Services -- Nova Scotia security portfolio for one simple reason: nothing's come along to replace them.

The Linux Foundation and edX have partnered to develop a massive open online course (MOOC) titled, "Introduction to Linux," to provide free training in open source software.

It appears that the police in Tallahassee, Florida have been busy tracking folks by their cell phones without bothering to show up before a judge and ask for a warrant. Why would they violate the constitutional rights of their citizens this way? Evidently because they were using technology on loan and had signed a non-disclosure agreement.

The next Ubuntu Long-Term Release, codenamed Trusty Tahr, will be released on April 17th, 2014 and will ship with several notable features, while mainly focusing on stable main components rather than bleeding-edge software, a very good decision which fits perfectly such a big release.

There will come a time (Precise ends April 2017, Lucid already stopped last year) when support will seize and quite possibly the repositories of their software packages will fold up as well; meaning that we won't be able to install new applications any longer.

One solution is to create your own repositories of all the software packages they offer.

Adlink’s new Linux-ready COM Express module packs a 4th Gen. Intel Core ULT processor, PCIe, and eight USB, four SATA, and three display ports in 95 x 95mm. The “cExpress-HL” is a trimmed down version of Adlink’s Express-HL computer-on-module, and similarly adopts the COM Express Type 6 (COM.0 R2.1) form-factor, but in the smaller, “Compact” […]

KDE has released the first beta of the 4.13 versions of Applications and Development Platform. With API, dependency and feature freezes in place, the focus is now on fixing bugs and further polishing. Your assistance with finding and fixing issues is requested! A partial list of improvements can be found in the 4.13 Feature Plan. A more complete list of the improvements and changes will be available for the final release in the middle of April. This first beta release needs a thorough testing in order to improve quality and user experience. A variety of actual users is essential to maintaining high KDE quality, because developers cannot possibly test every configuration. User assistance helps find bugs early so they can be squashed before the final release. Please join the 4.13 team's release effort by installing the beta and reporting any bugs. The official announcement has information about how to install the betas. Dot Categories: KDE Official News
