If my latest post on the topic did not tip you off, I am a Vim fan. So before some of you start stoning me, let me present you a list of "obscure Vim commands." What I mean by that is: a collection of commands that you might have not encountered before, but that might […]Continue reading...

The PRU-ICSS (Programmable Real-Time Unit and Industrial Communication Subsystem) coprocessor, typically shorthanded to PRU, is built into the Texas Instruments Sitara AM3559 system-on-chip that drives the Linux-ready Beaglebone Black SBC. The Sitara SoC’s PRU, which comprises dual, 200MHz, 32-bit RISC microcontrollers, is designed for customizing I/O that requires deterministic, real-time processing and ultra-low-latency. Yet, the PRU is so notoriously difficult to program, most BB Black hackers are hardly aware it’s there.

Tomorrow (November 7th) we’ll be hosting a testday for the Server Product. Members of the Server Working Group as well as QA will be available on freenode in the #fedora-test-day channel to help out with testing. The focus of the testday will be on several facets of the server product:

Ubuntu 14.10 LAMP server tutorial with Apache 2, PHP 5 and MySQL (MariaDB) LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache 2 webserver on an Ubuntu 14.10 server with PHP5 support (mod_php) and MySQL support. Additionally, I will install phpmyadmin to make MySQL administration easier. A LAMP setup is the perfect basis for CMS systems like Joomla, Wordpress or Drupal.

The final day of keynotes at OpenStack Summit delivered even more user stories from a variety of disparate industries who all share a common need for making the deployment of virtual infrastructure fast and easy. 

The openSUSE 13.2 release debuted this week, providing users with a long list of new and updated features. Among the interesting additions is the use of dracut which helps to accelerate system boot times.

The last year has produced a rogues' gallery of vulnerabilities in transport layer security implementations and new attacks on the key protocols, from Heartbleed to the Apple gotofail flaw to the recent POODLE attack. To help developers and security researchers identify applications that are vulnerable to known SSL/TLS attacks and configuration problems, Google is releasing a tool that checks for these problems.

The themes of a lot of our Raspberry Pi guides revolve around the size and portability of the Pi itself, lending it to tasks you may have used a full-sized or small computer for in the past that the Pi can now take over. Having your own private cloud is another excellent use of the Raspberry Pi’s capabilities, because you can store it hidden away somewhere and it will require very little day- to-day maintenance.

Smaller than a credit card, BITalino is a low-cost hardware and open source software toolkit, aligned with the DIY (do-it-yourself) movement. It enables anyone to create quirky and serious projects alike for wearable health tracking devices. The base kit includes sensors to measure your muscles, heart, nervous system, motion, and ambient light—and it includes a microcontroller, Bluetooth, power management module, and all the accessories needed to start working.

If you want to spark a religious war, express an unshakeable preference for a programming language, and by preference, make your favourite something relatively obscure, like Erlang. It turns out, according to a study by a bunch of UC Davis boffins, the differences in code quality between languages are pretty small.

Look beyond London, and one of the largest concentrations in Europe of all things innovative in IT is Manchester, which – despite having a quarter of London’s population, and little of the media and government attention – has a thriving tech start-up scene supported by a range of groups covering every technology or business methodology; the Lean Agile Manchester meet-up group alone has nearly 400 members.

Firefox for mobile, codenamed Fennec, is the build of the Mozilla Firefox web browser for devices such as Android smartphones and tablet computers. Fennec is available in multiple languages, and just a few months ago, was launched in the Hindi language along with others like: Assamese, Bengali (India), Gujarati, Kannada, Maithili, Malayalam, Marathi, Oriya, Punjabi, Tamil, and Telugu.

As has become regrettably typical for the Fedora project, the first Fedora 21 beta is well behind schedule. According to the current schedule on the Fedora wiki, the final version will arrive about a month late, on 9 December. That is if nothing goes wrong during the beta testing phase that's just started.

Canonical, the company behind the popular Ubuntu Linux distribution, says it's working on a new "virtualization experience" based on container technologies – but just how it will operate remains something of a mystery. Canonical founder and erstwhile space tourist Mark Shuttleworth announced the new effort, dubbed LXD and pronounced "lex-dee," during a keynote speech at the OpenStack Expo in Paris on Tuesday.

Diamond Systems released the EMX standard in 2011 as an industry standard supported by its EmbeddedXpress.org organization. The only EMX format SBC we’ve seen so far, however, is Diamond’s Intel Atom E680T-based Altair SBC, which is a true single-board design. Now, Diamond is offering a ruggedized, EMX-sized, sandwich-style SBC that incorporates COM Express Basic modules powered by Intel’s 3rd Generation “Ivy Bridge” Core CPUs. The “Vega” SBC is designed for rugged industrial, medical, on-vehicle, and military applications, and is also offered as part of a rugged “Raptor-Vega” embedded PC (see farther below)

Micro/sys unveiled an EPIC-sized “SBC4661? SBC that combines a Freescale i.MX6 Quad SoC with a Xilinx Kintex-7 FPGA, and offers extensive camera support. The last time we heard from Micro/sys, George W. Bush was president, and Intel still had a processor architecture called XScale. Like the circa-2008, XScale-based RCB1626 single board computer, the new SBC4661 runs Linux and uses the StackableUSB expansion interface.

The concept is simple; invite geeks of varying backgrounds to a central location for a weekend, supply them with food, drink, and an interesting problem, and see what happens. Kind of like the 40 Hour Famine, but with more eating, and labour donations instead of money. ThoughtWorks, an agile developement and design company, hosted and sponsored (among other sponsors, like Red Hat) the second annual Health Hack in Melbourne, bringing researchers together with technologists at their office in Melbourne’s central business district for 48 hours to create software that solved a problem in the health sciences. All the code developed at Health Hack would be released under an open source license, and in most cases, took advantage of some form of open data.

FirefoxOS_for_press_releaseMozilla, the mission-based organization dedicated to promoting openness, innovation and opportunity on the Web, is pleased to announce that Firefox OS will soon expand to Africa. The Firefox OS ecosystem has gained support from three new key partners in the region: Airtel, MTN South Africa and Tigo, operated by Millicom, are the first carriers working with Mozilla to soon bring first Firefox OS smartphones to Africa.

Facebook has never had much of a reputation for letting users hide their identities online. But now the world’s least anonymous website has just joined the Web’s most anonymous network. In a first-of-its-kind move for a Silicon Valley giant, Facebook on Friday launched a Tor hidden service, a version of its website that runs the anonymity software Tor. That new site, which can only be accessed by users running the Tor software, bounces users’ connections through three extra encrypted hops to random computers around the Internet, making it far harder for any network spy observing that traffic to trace their origin.
