How I came to find Linux | Ian Murdock. I saw my first Sun workstation in the winter of 1992, when I was an undergraduate at Purdue University. At the time, I was a student in the Krannert School of Management, and a childhood love of computers had just been reawakened by a mandatory computer programming course I had taken during the fall semester (we were given the choice between COBOL and FORTRAN—which even in 1992 seemed highly dated—and I had picked COBOL because it seemed the more “business” of the two). Ten years or so earlier, my father, a professor of entomology at Purdue, had replaced his typewriter at work with an Apple II+. Thinking his nine-year-old son might get a kick out of it, he brought it home one weekend along with a Space Invaders-like game he had bought at the local ComputerLand. I spent hours on the computer that weekend. Before long, I was accompanying Dad to the lab at every opportunity so I could spend as much time on the computer as possible.
My appetite for UNIX was ravenous that winter. Erchache2000 sur Twitter : "Linux es a prueba de bombas joder!!! Operativo #linux #debian... Copy-Paste from Website to Terminal. You surely know this: You're looking at some website with some useful shell commands. However, those commands are long as hell and you know you're probably not gonna need them for a few years or so (so there's no need to memorize them). So, what do you do? You copy-paste them. Here's an example: git clone /dev/null; clear; echo -n "Hello ";whoami|tr -d '\n';echo -e '! Try running this command in your terminal. There are some good comments and suggestions on how you can mitigate this kind of attack on reddit and Hacker News. Please note that Bracketed Paste Mode DOES NOT always fix this because the end sequence can be inside the text you paste unless your terminal emulator filters out the bracketed paste characters when pasting!

Oficina de Software y Hardware Libre Universidad Miguel Hernández UMH » Las mejores distros de Linux. El término distro es como se conoce coloquialmente a las distribuciones de GNU/Linux. Swapnil Bhartiya hace una recopilación en Linux.com sobre las mejores: La distro más bonita: elementary OS No hay ninguna duda de que elementary OS es la distribución basada en Linux más hermosa. La razón es simple: está siendo desarrollada por algunos de los mejores diseñadores del ámbito open source o código abierto.
Con el fin de ofrecer una experiencia consistente a través de aplicaciones básicas (como el navegador o editor de texto), han creado sus propias aplicaciones y han elegido las que encajan perfectamente con su propia filosofía de diseño. Elementary OS está claramente inspirado en Mac OS X; es un sistema operativo limpio que se ve estéticamente muy bien y que funciona según lo esperado. La mejor distro para ordenadores de sobremesa: openSUSE openSUSE hace que sea muy fácil la instalación de software de terceros a través de su ‘One Click Install’ en software.opensuse.org.

From the open source community to the maker community, individuals are changing the way software and hardware are built.
Together they are advancing the most exciting areas of technology, from Linux to cloud and supercomputing to consumer electronics, the Internet of Things (IoT), commercial drones and much more. That’s why access to learning is more important than ever. We’ve focused a lot of attention in recent years on making Linux learning materials more accessible to more people. What’s even more overwhelming is that our Intro to Linux course saw one of the highest enrollments of any class offered on edx.org this year. Through the process of bringing Linux to more people, we’ve learned quite a bit ourselves and are putting those lessons into action.

Rebooting on Mars. If you think fixing computer problems on your PC is a pain, trying fixing them from 125 million miles away. That's exactly what NASA's JPL Mars Exploration Rover (MER) team will be doing soon. The Opportunity rover, which has been exploring Mars for ten years now, has been randomly rebooting for several months. Because the rover always came back, the team tried ignoring the problem, but just like you with a misbehaving computer, the day finally came when they couldn't put up up with it anymore.
The scientists believe that the rebooting is happening because of trouble with the Opportunity rover's 256MBs of flash storage. This isn't the first time aging flash memory has given the rovers trouble. Flash memory, when used properly, in a solid-state drive can have a longer effective life than a hard drive. Before reformatting the flash drive, NASA will be downloading all useful data remaining on it and switching the rover to an operating mode that does not use flash memory.

The 42nd edition of the TOP500 list of supercomputers has been released, featuring the most powerful Linux machines in the world.
Leading the pack again is Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, with a performance of 33.86 petaflop/s on the Linpack benchmark. Tianhe-2 uses the Kylin Linux operating system (OS). The newest supercomputer to make the Top 10, Piz Daint, is also the most energy efficient system in the Top 10, consuming a total of 2.33 MW and delivering 2.7 Gflops/W. The number two computer, Titan is also one of the most energy efficient systems, consuming a total of 8.21 MW and delivering 2.143 Gflops/W. The newest supercomputer to make the Top 10, Piz Daint, is also the most energy efficient system in the Top 10.

Linuxfoundation : [Review] Inforce IFC6410:... Inforce IFC6410: Quad-Core Snapdragon SBC for $150. The Inforce IFC6410 contains a 1.7Ghz quad core Krait Snapdragon 600 CPU with 2GB of RAM, wifi-n, Bluetooth 4, a SATA port and 4GB of flash on board. The Snapdragon 600 chip is very similar to the chip found at the heart of the 2013 Nexus 7 tablet and Nexus 4. So another way to look at the IFC6410 is as a current generation Android device without a battery and screen but with gigabit ethernet and SATA. The first thing that stands out about the board is that there are no fans or heat sinks. All that CPU performance is coming without much heat overhead.
The box came with the IFC6410 machine and a power supply (USA plug 100-240V input). A micro USB port which can be used to obtain a console (and root access) is nestled between the two silver headers, one is audio out and the other is ethernet and USB ports. Gaining Root Access I used two versions of Android with the IFC6410, both of which were shown as version 4.1.2.

The Cubieboard brings SATA connectivity to a very low price point ARM Single Board Computer (SBC). The board has an ARM A8, 1Gb of RAM, 4Gb of Flash storage, HDMI output, and a whole bunch of IO pins. A recent update, the Cubieboard2 is now out, which replaces the Allwinner A10 CPU from the original Cubieboard (single A8 core) with a dual core Allwinner A20 (two A7 ARM cores). Given the Allwinner A10 CPU is an A8 core it might perform slightly better in single threaded tests per clock than the A7 cores in the Allwinner A20 CPU. Shown in the picture is the Cubieboard and Developer Set. While no power transformer is supplied, you can run the Cubieboard off USB power with the supplied cable. If you are intending to power a SATA drive from the Cubieboard then you'll want to use a power supply rather than trying to power both the Cubieboard and SATA drive off the single USB power cable.

The Media Controller Guy, is a Linux kernel developer working on video capture and display. Here he tells us about the lucky introduction that got him involved in Linux and recalls the time a Taiwanese company tried to pay him $50,000 for the free software he developed. As are many of the developers we've profiled in our 30 Linux Kernel Developers in 30 Weeks series, Pinchart is motivated to work on Linux by more than money.
Laurent Pinchart, Linux kernel developer. Name: Laurent Pinchart What role do you play in the community and/or what subsystem(s) do you work on? I mainly focus on video capture (V4L2) and, more recently, display (DRM and FBDEV) support for embedded platforms. In addition to maintaining several video-related drivers, I am involved in the design and development of the media controller, V4L2, DRM and FBDEV subsystems, and even write documentation for their APIs.

LibreOffice ya permite colaborar en documentos a través de Internet. The Compiler That Changed the World Turns 25. Last year, Linux celebrated its 20th anniversary. The kernel that Linus Torvalds started as a hobby project helped the Internet bloom, challenged proprietary operating system dominance, and powers hundreds of millions of devices. From hacker toys like the dirt-cheap Raspberry Pi to most of the Top 500 Supercomputers, Linux dominates the computing industry.
But it wouldn't have been possible without GCC, which turns 25 today. Before Torvalds started hacking away on Linux, Richard Stallman and started the GNU (GNU's Not UNIX) project and part of that was the GNU C Compiler (GCC). A Short History of GCC and Linux The origin of GCC actually started in the free C compiler that Stallman started in 1984, based on a multi-platform compiler developed at Lawrence Livermore Lab. For many Linux enthusiasts, GCC has always just been. "I downloaded it immediately, and I used all the tricks I'd read about in the Emacs and GDB manuals to quickly learn its 110,000 lines of code.

The other day we ran into a good problem that our site has grown and we are in need of a new server. So we ordered the server and now we need to transfer all the files from the old server to the new one. But rather than downloading all the files to our local machines then re-cuploading them to the new server, we're going to show you how you can skip the middle man and transfer files from server to server. The only requirements is that you need to have SSH access to both servers. We're going to be using the Linux command scp which stands for secure copy.
We're going to be using the following options: r = recursively copy entire directories C = compression enable p = preserves modification times, access times, and modes from the original file Also, if you're going to transfer a lot of data between the webservers, you probably want to add the nohup command too. nohup runs a command even if the session is disconnected or the user logs out.

Desde noviembre del 2007, que decidí de forma unánime lanzar una revista completamente gratuita orientada al software libre y Linux. Por suerte el primer numero de la revista fue publicado el día 28 de noviembre de 2007. De ahí en más avanzamos mes a mes tratando de entregar una publicación mensual para que todos nuestros lectores puedan así descargar sin ningún tipo de acción adicional que un clic un nuevo archivo PDF.
La comunidad fue creciendo, los colaboradores sumándose, y la revista tuvo sus altos y bajos en relación a las fechas de salida. Por supuesto al ser realizada de forma colaborativa es que tenemos fechas de publicación a las cuales no podemos llegar con lo cual se han atrasado a lo largo de estos años algunos números. Hoy día tengo que serles sincero no es fácil llevar adelante la revista y recibir mes a mes las colaboraciones de todas las personas que hacemos la revista.
Con lo cual se me ocurrió la idea de lanzar este Crowdfunding para todo el 2014. ¿Que es Crowdfunding? eBox Platform » EBOX PLATFORM.
