How to install GlusterFS with a replicated volume over 2 nodes on Ubuntu 14.04 In this tutorial I will explain GlusterFS configuration in Ubuntu 14.04. GlusterFS is an open source distributed file system which provides easy replication over multiple storage nodes. Gluster File System is a distributed filesystem allowing you to create a single volume of storage which spans multiple disks, multiple machines and even multiple data centres.
"You should be able to use the Web without fear that a criminal or state-sponsored actor is exploiting software bugs to infect your computer, steal secrets, or monitor your communications," writes Google security researcher Chris Evans. To help make that a reality, Google has put together a new team of researchers whose sole purpose is to find security flaws in software—any software—that's used on the Internet.
I've never once made a model rocket. I've always wanted to, but apart from "tube with explodey rocket part", I really didn't know where to start with designing. I recently found an open-source application that should help me with my lack of rocket science know-how: OpenRocket.
On Jan 21, 2008, Marie Smith Jones died. Her death was not just a loss of one human being, she was the last speaker of the Eyak language. Eyak was spoken in southern, central Alaska. We permanently lost one color from the mosaic of our limited linguistic diversity. With a language, not only a language dies, but with it a part of a community's history, intellectual and cultural diversity, and cultural identity.
The embedded systems Linux distro, OpenWRT, has taken a step into the 1990s and added native IPv6 support. The release candidate is code-named “Barrier Breaker” and runs the Linux 3.0 kernel. OpenWRT 14.07's IPv6 support will at this point be of only limited end-user interest. However, it's an important move for the future, as a feature that might encourage more consumer kit vendors to implement OpenWRT, and it helps position the OS for Internet of Things applications that are going to need v6 support.
If you have a missing default gateway on your Redhat system you can add new route as per network interface or globally. Defining default gateway using ifcfg files, that is, defining it as per network interface basis takes a precedence over global system wide default gateway configuration defined by /etc/sysconfig/network configuration file.
The ISO images for the Cinnamon and MATE editions of Linux Mint 17 “Qiana” were updated and labelled “v2?. All the links were updated on the website and in the announcements to point to the new ISOs.
"The ousting of Eich, the DRM problem -- all those imbroglios have tarnished the image of Firefox," said Google+ blogger Alessandrom Ebersol. So, on one side, "agnostic users left Firefox because they were told its new CEO was a conservative bigot. The folks who care about freedom, privacy and open Internet left Firefox because of the DRM module to play Netflix."
National Instruments unveiled a 2 x 3-inch module that runs real-time Linux on a Xilinx hybrid ARM/FPGA SoC, and can be programmed graphically with LabView. NI’s new “sbRIO-9651? system-on-module (SOM) is aimed at simplifying the design of custom data acquisition and control systems, by offering full compatibility with the NI LabView graphical programming environment. Additionally, the module’s core hardware and software compatibility with NI’s cRIO-9068 “CompactRIO” controller is said to further accelerate custom designs by letting programmers develop and test their software on an off-the-shelf system prior to the availability of custom hardware based on the SOM. To that end, the sbRIO-9651 SOM and cRIO-9068 controller system both use the same Xilinx Zynq-7020 SoC, and run a common “NI Linux Real Time” software stack.
Debian Developer Jon Dowland writes: "It appears I have switched for good. I’ve been meaning to write about this for some time, but I couldn’t quite get the words right. I doubted I could express my frustrations in a constructive, helpful way, even if I think that my experiences are useful and my discoveries valuable, perhaps I would put them across in a way that seemed inciteful rather than insightful. I wasn’t sure anyone cared. Certainly the GNOME community doesn’t seem interested in feedback." What can we say to that?
Even simple build scripts show the power and flexibility of the emerging new build tool for JVM projects.

MySQL is one of the most popular open-source database management system in the world. When it comes to the security of your MySQL, backing up the databases it’s a must.
Rackspace has rolled out new cloud hosting plans that offer consultation service and even direct management of cloud servers, in addition to infrastructure.
In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.
Infinity Runner is a great looking first person action game that involves a lot of running. We give it a try to see how it performs.
Mozilla believes success in the 21st century depends on digital literacy: the skills people need to read, write and participate on the web. Maker Party is all about teaching these skills in a fun, hands-on way. Participants meet up with others at events of all sizes to explore the how and why of building apps and webpages with code, design, media and interactive elements.
