Upstream is a new podcast featuring interviews and conversations with people who are moving open source forward. The podcast is produced by Red Hat[he]#039[/he]s Open Source and Standards team. In their first episode, Joe Brockmeier talks with Leslie Hawthorn of Elasticsearch about her Sunday morning keynote at the Twelfth Annual Southern California Linux Expo (SCALE 12x) in February this year.
Matthew Miller has become project leader of Fedora Linux, the open source operating system sponsored by Red Hat.
Missed a Raspberry Pi project-focused issue of the magazine? We've compiled the 20 best projects into one cheaper digital bookazine you can get today. Over the past couple of years we’ve been able to bring our readers an amazing array of Raspberry Pi projects that we are genuinely proud of. From big projects such as building your own robot and quadcopters down to the little stuff like making melodies with Sonic Pi or making Pong.
There a few reasons why you might want to build your own distribution. You might want to build a custom install CD to match the policy of your organisation. For example, a GNOME desktop with Chrome as the web browser might be the standard desktop where you work. That touches on another motivation for wanting to create a customised installer: sometimes the creator of the distribution makes a decision that you simply don’t like. Canonical’s decision to switch to its own UI, Unity, ranks amongst its most controversial decisions. However, by using some of the methods that we explore here, you could create a distribution that is standard Ubuntu, but with a traditional desktop that you are more comfortable with.
Want a fully open source Platform-as-a-Service cloud framework? Apache's just made Stratos a top-level project.
With fewer defects being found in major open source projects than in large proprietary software packages, what are the security strengths and weaknesses of open source development?
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects. A denial of service flaw was found in the way Squid processed certain HTTPS requests when the SSL Bump feature was enabled. A remote attacker could send specially crafted requests that could cause Squid to crash.
With Linux Mint, however, there is a particular focus on the Cinnamon desktop, which was created by the Linux Mint distribution itself. In this slide show, eWEEK examines some of the key features of the Linux Mint 17 Cinnamon release.
Peter Lohrmann has been working on Valve's VOGL debugger to make it easier to use for developers looking to it for help.
Joonas Kuorilehto discovered that GnuTLS incorrectly handled Server Hello messages. A malicious remote server or a man in the middle could use this issue to cause GnuTLS to crash, resulting in a denial of service, orpossibly execute arbitrary code.
Cavium and Canonical have expanded their partnership to support ThunderX SoC solutions on Ubuntu Linux for OpenStack and the data center, which could open new doors for Ubuntu and open source on ARM64 devices, OpenStack cloud servers and other enterprise hardware.
Piwigo is open-source photo gallery software for the web, built by an active community of users and developers. Piwigo extensions make it easily customizable and highly flexible. Piwigo is free and open source software.
Over the last few columns, we’ve looked at some fundamental concepts in Python, concerning objects, object- oriented programming and how objects are stored in memory. This issue, let’s take a look at the Raspberry Pi and one of the unique features not usually offered on single-board computers. Of course, I’m speaking of the GPIO pins. GPIO stands for general-purpose input/ output. The pins provide an interface between the Raspberry Pi and the outside world. They can act as either inputs into the computer, or outputs to the world. With the addition of these pins, the possibilities for the Raspberry Pi explode. It goes from being simply a single-board computer to a project platform.
The KDE Applications 4.13 announcement highlighted the delightful new capabilities of Palapeli, the KDE jigsaw puzzle application. What the announcement did not mention is that the Palapeli maintainer, Ian Wadham, is celebrating 50 years of software experience. He’s ready to hand off Palapeli and his other KDE software development responsibilities. Albert Astals Cid called attention to Ian’s achievements and suggested a Dot interview.
