ELF Executable Signing/Verification Comes For Linux
Vivek Goyal of Red Hat has published the initial Linux patches for implementing ELF executable signing and verification. This support is similar to Linux kernel module signature verification and is necessitated with the arrival of SecureBoot.
Making commercial open source software
I recently blogged about making open source software, and the high level steps for how to think about the process. We started with the need for software to seed the discussion, the need for clear motivation as to why to publish as open source software, and then the structural requirements to build a community (license choice, collaboration platform or forge, and governance considerations).
Red Hat Revenues: Partners Drive 65 Percent of Bookings
Red Hat (NYSE: RHT) now generates 65 percent of quarterly bookings from partners, up from 53 percent in the company’s Fiscal Year 2008. That’s impressive. But how is Red Hat going to train partners to cross-sell the company’s growing portfolio of software — Linux, storage, virtualization, middleware, etc.? Oh, and who are Red Hat’s top current partners? Here are all the answers — or so The VAR Guy claims.
Is your screen blanking in Xfce despite your xscreensaver settings? I have the fix -- and this time it's for real
Some readers might have seen this post appear and disappear, appear and disappear again. That's because my first "fix" for this annonying Xfce problem didn't really work. Neither did my second attempt. Nor my third. Screw proverbs. The fourth time now seems to be "the charm."
Advanced Image Processing with GIMP and G’MIC
If you’re a digital artist or designer, you’ve no doubt heard of the GNU Image Manipulation Program (GIMP), often referred to as the preeminent open-source alternative to Photoshop. But did you know that you can extend GIMP’s features dramatically with a plugin called G’MIC?
Dive Into a Solid Collection of OpenStack Cloud Tutorials
It's hard to believe that we're only a couple of years into the OpenStack story. Back in 2010, Rackspace and NASA announced an effort to create a sophisticated open source cloud computing infrastructure that could compete with proprietary offerings. Since then, OpenStack has won over countless tech titans that are backing it, and has its own foundation.
Python Scripts as a Replacement for Bash Utility Scripts
For Linux users, the command line is a celebrated part of our entire experience. Unlike other popular operating systems, where the command line is a scary proposition for all but the most experienced veterans, in the Linux community, command-line use is encouraged. Often the command line can provide a more elegant and efficient solution when compared to doing a similar task with a graphical user interface.
Magnolia Announces Guest Speakers for Amplify 2013: MBC Group, Atlassian, Manatee County

Oracle Java JDK 7 on Ubuntu Linux - Source or RPM Installation
In the previous article we have discussed how to install OpenJDK java on ubuntu from the standard Ubuntu repository or Oracle's Java JDK 7 using Personal Package Archives ( PPA ). This article will cover installation of Oracle Java JDK 7 from a source package or by converting RPM Java package to the Debian software package format.
Postal 2 now available for Linux on Steam!
For those of you who didn't already know Postal 2 is now on Steam for Linux! Live a week in the life of "The Postal Dude"; a hapless everyman just trying to check off some chores. Buying milk, returning an overdue library book, getting Gary Coleman's autograph, what could possibly go wrong?
Crusader Kings II: Linux port, Republic video and some excellent patch notes
We’ve already brought you a lengthy interview and expansive rundown on the new additions of Crusader Kings 2?s Republic DLC expansion. But in the wake of its release, there’s some CK2 news housekeeping to be done. The big news is the addition of a Linux version, but instead I think we’ll kick off with the patch notes. They contain the sentence “Constantine de Hauteville is no longer female,” which is just too good to pass up.
Upgrading Fedora 17 to 18 with FedUp is elegant, but …
With Fedora 18, the recommended upgrade tool is called FedUp (FEDora UPgrade). It is, by design, a lot more elegant than what it replaced, but how well or error-free it works is another matter.
Free Resource: A Manager's Guide to Building a Product with Embedded Linux
According to a 2012 survey of embedded engineers by both VDC Research and UBM Electronics, the use of Linux in embedded projects is increasing at a fast rate. UBM reported that some 35 percent of embedded developers are working on Linux projects and that number increases to 48 percent when Android is included. This is not a surprise to us. Increasingly, we have been working with companies big and small who are replacing proprietary embedded OS with Linux in our training and events programs, as well as membership. Among the reasons companies elect to use embedded Linux in their projects are the availability of the source code, the strength of the Linux community, the lower costs, and the availability of Linux developer talent (even though there is a lot of competition for good developers).
The forkers saving open source from a corporate bear hug
Open source has long had a strong corporate element to it, perhaps starting in earnest when IBM pledged to spend $1bn on Linux back in 2000. Despite the benefits of corporate funding of open-source software - more money, more source code written - some question whether open source has become too corporate. For those who worry about the commercialisation of open source, I'd like to introduce you to Pedro Algarvio, contributor to the SaltStack project.

Sega announced today, January 15, 2013, that the upcoming The Cave game development by Double Fine and designed by Ron Gilbert, will be made available for Linux-based operating systems and Apple’s Mac OS X next Wednesday, January 23.
Memo to Linux Devs: Focus on Design, Not Technology
In the open source channel, many developers could stand to focus a bit less on technology itself, and a bit more on making products look and feel smart, intuitive and elegant–especially when it comes to communicating with end users. Most Linux distributions don’t get this right, but Canonical, the company behind Ubuntu Linux, shines as an outlier. Here’s how.
Xvidcap Records Screen Activity Nearly Effortlessly
Xvidcap is a small tool to capture whatever goes on within the borders of an X-Windows display. It lets you capture what you do either as individual frames or as an MPEG video. Recording your computing activity keystroke by keystroke is not a need every computer user has. However, this is an ideal tool if you need to make a visual record of the steps you take to complete a computing task.
Double Joy: A Good Day For Linux Game Announcements
Not only has the immensely popular Crusader Kings II from Paradox gone on sale on Steam, but Double Fine has announced that their adventure game disguised as a side-scrolling platformer, The Cave, will also be on sale on Steam from the 23d of January. With any luck this sets the tone for the rest of the year.
Advanced Vim registers
Registers in Vim are best thought of as scratch spaces for text, some of which are automatically filled by the editor in response to certain actions. Learning how to use registers fluently has a lot of subtle benefits, although it takes some getting used to because the syntax for using them is a little awkward.
