The upstart Spark Linux tablet is up for pre-order at makeplaylive.com for a target price tag of 200 euros (about $263 USD). You can indicate how many tablets you’re interested in, and your priority number will ensure you’re among the first to receive yours. The Spark folks are hoping to get a strong sense of device demand before the tablet launches. Developer Aaron Seigo also posted a new blog today discussing the financial aspect of the project. Overall, the idea is to put money that comes in back into the project and to Free Software (especially those around open devices) in general. At first, the money will go into developing Plasma Active and Mer, and from there, funding will be directed to whatever areas of the Spark project are currently in the most need. “Where these funds will be targeted will depend on what needs doing, what needs supporting the most and how successful the products are in the market,” said Siego in the post.
Linux Journal - August 2012 - Page 46-47. Les commandes fondamentales de Linux - Linux France. Premier auteur (jusqu'à 1998): Armand Delcros Wikisé et étendu par (depuis 2009): Nat Makarevitch Contributions et remerciements Nat Makarevitch pour ses nombreuses critiques et corrections, Thomas Ortega pour ses bienveillantes remarques et la remise en forme HTML du document, Kim Ashue pour sa relecture, Philibert de Mercey pour son aide à la mise en page, Fanthomas pour sa relecture. L'objectif de ce document est d'enseigner les commandes fondamentales de Linux (et donc d'Unix).
Objectifs Nous explorerons ce qu'offre le shell nommé « bash », le plus utilisé sous Linux, donc une partie de ce que peut faire un utilisateur capable de diriger la machine en créant des lignes de commandes plutôt qu'en se contentant d'un cliquodrôme. Manœuvres préliminaires Pour apprendre il faut pratiquer, donc disposer d'une machine fonctionnant sous Linux qui n'est pas sérieusement exploitée.

All the world may be agog over Microsoft's Windows 8 previews this week, but at the same time a quiet revolution is taking place.
It's powered by Linux, it costs a fraction of Windows' price, and its first tangible evidence is now available in not just one but two “sweet” forms: Raspberry Pi and Cotton Candy. Like the idea of freedom from the upgrade treadmill and a price that won't put you behind on your rent? Then you may want to check out this new category of computing devices. The Raspberry Pi There's been talk about the ARM-based, education-focused $25 Raspberry Pi for quite some time already, but this week the diminutive device made its official debut. That's been nothing if not exciting to watch, particularly because the launch was so successful that it brought the UK-based project's site to its knees amid overwhelming demand. Premier Farnell and RS Components have both signed up as licensed manufacturers of the devices, the first run of which apparently sold out within an hour or so.

Linux : Configurer la Raspberry sans écran. François, Si vous avez accès à votre routeur, vous pouvez utiliser votre routeur pour trouver l'adresse IP de votre RPi, qui devrait être acquis via DHCP. Vous pouvez ensuite SSH à l'aide d'un programme appelé PuTTY. Cela vous permet d'obtenir une fenêtre de console et vous pouvez commencer à configurer le serveur VNC pour exécuter au démarrage. Ensuite, vous pouvez utiliser VNC pour accéder à l'interface graphique de votre RPi. Je n'ai pas mon RPi relié à un moniteur, et l'utiliser exclusivley via SSH et VNC. Quant à la carte mémoire, ne vous inquiétez pas à propos de ce que vous voyez dans Windows. Amusez-vous! PS: j'ai utilisé Google Translate pour prendre votre message du français à l'anglais, puis d'écrire cette réponse.

Accessing Hardware. With Raspberry Pi and Cotton Candy, Linux Launches a Revolution. Copier une puce RFID avec cet émulateur. Le montage RFIDemulator, créé par l’allemand Alexander Guthman, permet de simuler n’importe quelle puce RFID à 125 kHz compatible EM4001. Ce montage électronique est fort intéressant car c’est un gadget permettant de cloner la moindre puce RFID comme par exemple celle contenu dans votre badge pour pointer au travail. Au niveau de la conception, pas un composant compliqué, on retrouve principalement un MAX232 avec sa batterie de condensateurs pour la liaison série et un micro-contrôleur Atmel ATmega8 gère l’ensemble. On peut d’ailleurs voir sur le schéma suivant la simplicité du montage. Avant toute chose il faut capturer l’ID 64 bits d’une puce puce RFID compatible EM4001 à l’aide d’un lecteur RFID. Un programme (disponible sur le site de l’auteur) permet alors d’envoyer ce code via une liaison série RS232 à l’émulateur, qui va alors transmettre via la bobine de cuivre ce code ID 64 bits codé en Manchester.
Voici la vidéo de démonstration d’utilisation de l’émulateur RFID : Speech Recognition using the Raspberry Pi | aO(N²) I've finally received my Raspberry Pi, and I've immediately gotten to work transferring the speech recognition system I used for the robotic arm to the pi. Due to its small size and low power requirements, the Raspberry Pi is an excellent platform for the Julius open-source speech recognition system. This opens up almost limitless possibilities for voice command applications. EDIT: I am no longer working on Julius/HTK for speech recognition.
Please see this post for more information. There do exist commercial offerings of electronic voice command modules, as well as voice command applications appearing in recent smartphones (i.e. In this tutorial, I will be demonstrating how to use the Raspberry Pi for a simple speech recognition system to control the Maplin USB Robotic Arm.

Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte! Adafruit’s custom Rasp Pi distro eases some pain. Raspberry Pi : le micro-PC à 25 euros fait un carton. 01net le 29/02/12 à 12h41 Il est en vente ! Le Raspberry Pi, ce PC britannique de la taille d’une carte de crédit, commercialisé à un prix défiant toute concurrence (environ 25 euros !) Ce mercredi 29 février, est bien parti pour faire un carton. Les deux sites partenaires de la fondation Raspberry pour ce lancement ont été pris d’assaut. A tel point qu’ils sont tous deux tombés sous les requêtes des internautes désireux d’acquérir cette machine atypique. Inutile de se presser désormais : l’ordinateur est déjà sold out sur les deux sites, et l’un d’entre eux est encore très difficile d’accès à l’heure où nous écrivons ces lignes. Afin de limiter au minimum le coût du PC, les composants ont été sélectionnés avec soin.

The Raspberry Pi will not start without a properly formatted SD Card, containing the bootloader and a suitable operating system.
You will also need to choose a distribution. Some Raspberry Pi kits will come with a ready-to-go card with the distribution pre-installed, or these can be bought separately. If you don't have a pre-installed card you will need to prepare your own. Buying a preloaded SD card from a reputable supplier means that you can just plug it in and power up your Raspberry Pi; it should then just work. Using NOOBS Using Etcher. The Raspberry Pi Launch. RPi Easy SD Card Setup. Raspberry Pi Kernel Compilation. The Raspberry Pi cannot run a vanilla Linux kernel. A patched version of the kernel is maintained by the Raspberry Pi Foundation and is available from their github Prerequisites To compile a kernel, you require dev-vcs/git to download the source code and genkernel to manage the build process. root # emerge --ask git genkernel Get the Kernel Source root # cd /opt root # git clone --depth 1 # ln -s /opt/linux /usr/src/linux Compile and Install the Kernel Note Compiling will take about 6 hours.
Using genkernel you can build a linux kernel with support for many different features. Default Kernel In this example the configuration options from the running kernel are used to compile the new kernel. root # genkernel --kernel-config=/proc/config.gz kernel After the kernel has compiled it will be installed into the /boot folder.

Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte! Raspberry Pi, Python & Arduino. After the other night’s wonderfully slow detour into Processing, I thought I’d try the Raspberry Pi’s “native” language of Python to control an Arduino. This worked rather well, though I don’t have a slick GUI for it yet. pyFirmata is the magic that allows an Arduino running Firmata to talk to Python. It’s fairly easy to install under Raspbian: Get the required packages:sudo apt-get install python-serial mercurialDownload the pyFirmata code:hg clone cd pyfirmata sudo python setup.py install (If this succeeds, you can delete the pyfirmata folder.)
Using pyFirmata is a bit different from other Arduino applications: Here’s some code that uses the same hardware as before, but simply reports the temperature and ramps the brightness of the LED up in 10% steps. The output from this might look like: If this doesn’t work, check the output of dmesg to see if you’re using the right port. Which should generate something like Send the author to the moon! Raspberry Pi: now what? Introducing the mintBox. In association with CompuLab, Linux Mint is proud to present the mintBox. The pro model is recognizable by its ribbed case (its faster performance requires more heat dissipation) We’re passionate about what we do and for our very first Mint device, we wanted something unique, something special and extraordinary. The mintBox is Mint in a box. It’s tiny, it’s silent, it’s extremely versatile and it comes packed with connectivity. The mintBox is the very first branded Mint device About CompuLab CompuLab has been making embedded computer-on-modules for over 15 years.
We work with CompuLab on the fit-PC3 to make sure the software tightly fits the hardware and to provide a high level of integration.
