A roundup of events in Fedora.

It is far more stable than its predecessors, and it continues to do basically everything I want it to do, so it's pretty good!

A project's choice of a license will have significant effects on its ability to sustain itself. Despite the rivers of ink that have flowed regarding the recent Heartbleed vulnerability, I believe the developer community has not addressed the right problem. Developers have fixated on a debate about one of open-source's most touted advantages: With many eyes looking at the code, is open source able to correct bugs faster than closed-source projects?

When AMD revealed an “ambidextrous” processor roadmap based on both x86 and ARM cores last Fall, it saved one surprise for today: they’ll be pin compatible!

I’ve found a few articles about using the Clojure programming language on the BeagleBone Black. However, all of them I’ve seen gloss over the installation steps. I got Clojure 1.6.0 running on my rev B BeagleBone Black (aka BBB from here on) and I’ve outlined the steps to do it in this post. If you haven’t done anything with your BBB yet, plug it in to a free USB port and open START.htm when it mounts as a drive.

You might be wondering why you might want to attach an Arduino to your Raspberry Pi. While there are lots of reasons, probably the most poignant is the extra six PWM-capable pins and another six analogue pins that a standard Arduino Uno offers.

Pinguy 14.04 RC is now available for testing. Pinguy OS is an Ubuntu-based distribution targeted at beginning Linux users. It features numerous user-friendly enhancements, out-of-the-box support for multimedia codecs and browser plugins, a heavily tweaked GNOME user interface with enhanced menus, panels and dockbars, and a careful selection of popular desktop applications for many common computing tasks.

Earlier this month Raytheon entered into a $15.8 million contract with the U.S. Navy to upgrade Raytheon’s control systems for unmanned aerial vehicles (UAVs), according to a May 2 Avionics Intelligence report. The overhaul, which involves a switch from Solaris to Linux, is designed to implement more modern controls to help ground-based personnel control UAVs.

One of Linux's advantages has always been that you rarely need to reboot it. Now, a new program, CloudLinux's KernelCare, tries to make rebooting totally unnecessary.

Today is the Day Against DRM, organized by the Free Software Foundation through their Defective by Design campaign against digital rights management (DRM), which they refer to instead with the more accurate moniker "digital restrictions management."

"People have been complaining about gEdit 3.12, which recently moved into Debian's "testing" repository. Specifically, they're complaining about the GUI. Many have lamented the old-style icon menu, which was removed, as is similarly being done to Totem (Videos), Nautilus (Files), and Disk Utility (Disks), among others. Personally, as a programmer, I honestly never used the old menu, I used the keyboard."

CloudLinux is introducting KernelCare, a new service for installing security updates on open source Linux kernels for virtual or physical servers without rebooting.

Short and easy method to return Firefox to its previous look and feel, with a side order of Linux and free software proselytizing. Some discussion of Debian's renaming policy as well.

When it comes to managing infrastructure deployments of a certain size, even a ninja sysadmin can't do it all without some help. In fact, one might argue that knowing when and how to use IT automation tools for managing infrastructure is a prerequisite to getting your admin blackbelt. Enter Puppet. 

Linux distributions like Ubuntu are release based, which means when a new version rolls out, everyone rushes to upgrade. Many folks do this without a care in the world, believing that if the previous version worked great then the latest version should also be free of bugs.

When it was released in 2011, Drupal 7 was the most accessible open source content management system (CMS) available. I expect that this will be true until the release of Drupal 8. Web accessibility requires constant vigilance and will be something that will always need attention in any piece of software striving to meet the Web Content Accessibility Guidelines (WCAG) 2.0 guidelines.

OpenSSL seems to be the source of numerous problems, especially now that people have started to look a lot more closely at the source. Yet another bug has been discovered in the OpenSSL package and, to make things worse, it's a four-year-old problem that has remained unsolved until now.

Command line wizards are forever encouraging the rest of us to learn regular expressions (regex). We're told regex is elegant, powerful and incredibly useful.

The downside is that regex can be seriously fiddly. One fly-spot out of place, and the code fails. For this reason I only use 'non-simple' regex when I absolutely have to. But when I do, sigh... Regex really is elegant and powerful, as the following example shows.

Can a compact and low-cost circuit board piggybacked onto the Raspberry Pi microcomputer’s GPIO header turn it into a high-quality audio powerhouse?

Difio is a Django based application that keeps track of packages and tells you when they change. It provides multiple change analytics so you can make an informed decision on when or what to upgrade. Difio was created as closed software, then I decided to migrate it to open source to allow for in-house deployments and attract a larger community around the project. 10 steps to migrate your closed software to open source
