Learning a new programming language can be a daunting experience. To help break down the barriers, this article presents our pick of the finest free programming books available to download over the net. There is 1 book selected per language, which made selection problematic to say the least.

Thanks to the recent fiasco of The Witcher 2 I wanted to write down some thoughts on why we shouldn't accept bad quality ports from developers.

For many years we've written about the serious problems with CAFC, the court of appeals for the federal circuit, which is better known as the appeals court where all patent cases go. CAFC was created in the early 1980s under the belief that a more "specialized" court could better handle the more complicated technical issues related to patents. But what really happened is that it basically built a club of patent-friendly judges, who spent nearly all of their time with patent lawyers, and thus took an increasingly patent-friendly view of the world.

Extra-governmental agencies, beyond democratic accountability, want to censor and control our free and open internet…

LXer Feature: 25-May-2014

In the news this week, the Gmail app crosses one billion downloads, never leave an unused Java file laying around, China bans Windows 8 in retaliation of Microsoft stopping XP support, Red Hat's new model, Linus Torvalds and the cult of personality in technology, the growing role of UEFI and a reborn FOSS laptop. Enjoy!

A few weeks ago, the Supreme Court smacked down the Federal Circuit (CAFC) for its made up rules that made it almost impossible to enable victims of patent trolls to get the courts to order the trolls to pay legal fees. As the Supreme Court noted, CAFC seemed to set up arbitrary rules for no reasons at all. And this is important, because courts almost never award legal fees, and with the untimely death of patent reform, hopefully this small change will at least help in the meantime.

Planetary Annihilation was already awesome for the sheer scale of the game and the fact that it's on Linux means we finally have a big RTS game. The developers have just released a brand new build containing a single-player mode called "Galactic War".

While Scratch may seem like a very simplistic programming language that’s just for kids, you’d be wrong to overlook it as an excellent first step into coding for all age levels. One aspect of learning to code is understanding the underlying logic that makes up all programs; comparing two systems, learning to work with loops and general decision-making within the code.

Robolinux 7.5.2 is the latest update of the project's Debian-based distribution featuring a pre-configured VirtualBox for running Windows as a "guest" operating system. We added Firefox 29 to Robolinux as our users did not like Iceweasel. So now Robolinux has the newest versions of Thunderbird and Firefox. We also updated our Debian-based operating system to the most current Debian 7.5 with upstream security updates and improvements. We updated VirtualBox to the latest version 4.3.12. We updated the proprietary AMD ATI Driver to the newest version. Robolinux has added more professional technical support staff to continue providing highly responsive support.

In this article we’ll be using Node.js and the Duino library to get real-time CPU data and display it with a series of LEDs. We’ll also look into adjusting the brightness of those LEDs with a potentiometer, and running the app as a background process with Forever.js.

Nowadays, it's just a sanctuary for my father to play marathon sessions of Diablo 3. But a little over 15 years ago, the breakfast nook in my parents' kitchen more closely resembled a coliseum where man (my father) was pitted against machine. Back then, it wasn't uncommon to hear strings of profanities streaming out of the room while he sat in front of a desktop computer hunched over in defeat -- all in an attempt to run Linux.

Bogus copyright claims on YouTube are getting more and more prevalent, but they only get exposure when they do damage to high-profile targets. Michael Tiemann is the Chief of Open Source Affairs at Redhat Inc. and apparently he can't use Creative Commons music in his uploads without being bombarded with copyright claims.

The announcement has gone out. The gist? Flash will no longer work with Chromium on Linux. Many of you are probably wondering, "What is Chromium?" Essentially, Chromium is the open-source version of Google's massively popular browser, Chrome. The big Flash debacle is simple: the old way of handling Flash (within a browser) is insecure. It was driven by the Netscape Plugin API (NPAPI) -- an architecture that dates back to Netscape Navigator 2.0. NPAI that's insecure, obsolete, and doesn't work well on smartphones and tablets -- which is a death knell in and of itself.

On Wednesday morning, tech sector lobbyists thought they were in the final stages of pushing through a hard-fought compromise on patent reform. "Tuesday night it was moving forward, Wednesday morning it was moving forward," said Julie Samuels, director of Engine, a group that lobbies for startups. "Then I looked at Twitter and there was a tweet saying it was dead. What the hell?"

AMD’s “Bald Eagle” R-Series processors offer four 3.6GHz “Steamroller” cores with Heterogeneous System Architecture support, plus Mentor Embedded Linux. AMD has a dual-platform strategy for embedded: G-Series on the low end and R-Series on the high end. Now, the chipmaker has launched a second generation of AMD Embedded R-series processors in both CPU and APU (accelerated processing unit) variants, with the latter offering integrated, rather than optional discrete AMD Radeon graphics. AMD tipped its Bald Eagle R-Series processors last September, and has launched sales for five new variants. The new R-Series CPUs are designed for gaming machines, digital signage, medical imaging, industrial control and automation, and communications and networking infrastructure, says AMD.

Flagship is a real-time strategy game set on a galactic scale, played from a first person perspective. Command your fleet from the bridge of your ship, explore the stars and expand your territory.

NVIDIA GRID Workspace is a virtualized desktop environment from NVIDIA that offers “cloud-delivered graphics acceleration for enterprise applications.” The NVIDIA GRID Windows client was released yesterday for a limited time only. Linux and Mac OS X are said to be in the works, so while I’m waiting for the Linux client to be released, I decided to test-drive the Windows client on an installation of Windows 7 Pro in a (VirtualBox) virtual environment.

Tobii announced a Linux-based eyewear device with advanced eye-tracking software that lets market researchers see what’s capturing the viewer’s attention. At first glance, Tobii Glasses 2 may look like another Google Glass competitor, but there’s more — and less — here than meets the eye. First, this is not a casual date: the glasses cost a whopping $14,900, and the Premium Analytics package goes for $29,900. Second, the eyewear is not designed for snapping photos of checking the Internet on the move. Instead, it lets researchers see what is captivating a test subject’s interest. The device can be used to watch what you’re looking at on a website, a TV screen, or signage, or when walking into a store or restaurant. They can analyze how you drive a car, train on equipment, or even play sports.
