Storm Energy has upgraded its “SunSniffer” solar plant monitoring system to a Linux-based platform running on a Raspberry Pi SBC. Germany-based Storm Energy is the latest of a growing number of companies building commercial products based on the hackable Raspberry Pi single board computer. The company’s SunSniffer system is designed to monitor photovoltaic (PV) solar power installations of all sizes, and the latest version can also control the equipment, says the company. The new SunSniffer version adds a Raspberry Pi SBC along with a custom expansion board and customized Linux OS, which combine to enhance the system’s flexibility and upgradability.

First unveiled in January, AMD today gave a detailed look at its first ARM-based server processor, the Opteron A1100 "Seattle."

The Pineapple is a small-form-factor device that runs on Linux and is loaded with tools to help enable penetration testers to gain access to the WiFi networks of their targets. The new Mark V device improves on the predecessor Mark IV device by including both the Atheros AR9331 and Realtek RTL8187 wireless chipsets.

New SPIR spec makes compute kernel compilation a breeze. Siggraph 2014 As the 41st Siggraph computer graphics conference kicks off in Vancouver this week, industry standards body the Khronos Group has announced updates to two of its most important specs.

The creator of an ultra-secure email service once said to be used by Edward Snowden unveiled his next project at a major hacker conference Friday: he and others like him want to change the very nature of email forever.

Garry’s Mod, developed by Facepunch is without a doubt one of the most enjoyable and hilarious games that I have ever played. Out of the box, the game is perhaps one of the ultimate sandbox games available anywhere. You spawn in the middle of an open area that you choose and you can spawn in just about any item or NPC that you can think of. This game is also probably one of the best physics simulators available. The entire game revolves around physics. In this game you are able to do whatever you heart desires and although I say that with a lot of different games, I truly mean it with Garry’s Mod. Whatever you want. If you want to build an airplane out of a bathtub and some planks of wood, then be my guest. You can simply spawn in the materials that you want and then use tools to “weld” them together. Using weight tools you can make these items very light, which will allow them to become airborne. This game definitely deserves lots of praise.

elementary OS Freya Beta has been announced by its developers and it comes with an Ubuntu 14.04 base and lots of new features.

The beta release of third elementary OS out now and is recommended mainly for developers and testers. It includes updates to drivers and the Linux kernel along with GTK 3.12

We're all familiar with the idea of virtualized computers. Not only are they a great way to better utilize resources in a server room, but they also allow you to create and destroy servers in the blink of an eye. That's perfect for a lab or training environment. Unfortunately, it's always taken a rack of actual hardware to create a training lab for Cisco hardware.

It’s been exactly one year since the release of the second version of elementary OS. On this, the day of our Lunaversary, we’re proud to make the first beta of elementary OS Freya publicly available for developers and testers.

At first glance, it might look as if there’s very little for what blogger Gary Newell calls the Everyday Linux User, those who have adopted free software at home or in a mom and pop business. To my eyes, there is barely enough — but that still qualifies as enough.

It has been exactly one year since the release of the second version of elementary OS. On the day of our 'Lunaversary', we're proud to make the first beta of elementary OS 'Freya' publicly available for developers and testers. Freya inherits core components from Ubuntu 14.04.1 LTS such as the Linux kernel (version 3.13), hardware drivers, and graphics stack. This includes support for EFI stub-loading, which is a kernel feature that enables booting directly from (U)EFI, without the need for an additional bootloader such as GRUB. Ubiquity does not yet have support for this configuration, but one of our developers has created a guide for a GRUB-free install of Freya on modern Mac computers using rEFInd.

In previous posts we’ve seen how to Enable automatic security update in Debian/Ubuntu and in Red hat enterprise or Centos 6, recently I’ve started to work with the new Red Hat Enterprise 7 and I’ve noticed that there are some interesting changes in the way this system can be set to auto update.

An example ?

In Red Hat/Centos 6 you could not set which kind of update you’d like to do, so you could just decide to update for any kind of update (feature,bug or security) or nothing at all, this has changed and now we can fine grain which kind of updates we want to do on our servers.

A typical data file often has associated "metadata" which is descriptive information about the file, represented in the form of a set of name-value pairs. Common metadata include creator's name, tools used to generate the file, file creation/update date, location of creation, editing history, etc. EXIF (images), RDF (web resources), DOI (digital documents) are some of popular metadata standards.

Open is about sharing and collaboration. It's the idea that "we" is more powerful, more rewarding and fulfilling than "I". I can't promise jobs, but I do know that open is becoming very big. Governments and funders are pushing the open agenda, even though academics are generally uninterested or seriously self-interested. read more

You can install any modern Windows or Linux version, desktop or server, using Hyper-V in Windows 8.1. But you'll need to bring your own license and software for the base OS. Here's how to get that OS cheap or even free.

School will soon be in session and a Chromebook may be just what you need for the coming academic year.
