XMPP - Extensible Messaging and Presence Protocol - Wikipédia - 0 views

  • Extensible Messaging and Presence Protocol
  • Extensible Messaging and Presence Protocol (qu'on peut traduire par « protocole extensible de présence et de messagerie »), souvent abrégé en XMPP, est un ensemble de protocoles standards ouverts de l’Internet Engineering Task Force (IETF) pour la messagerie instantanée, et plus généralement une architecture décentralisée d’échange de données. XMPP est également un système de collaboration en quasi-temps-réel et d’échange multimédia via le protocole Jingle, dont la Voix sur réseau IP (téléphonie sur Internet), la visioconférence et l’échange de fichiers sont des exemples d’applications.

Encyclopédie de L'Agora | Henry David Thoreau - 0 views

  • Henry David Thoreau
  • Lorsque les Puritains arrivèrent en Amérique du Nord, c’est tout naturellement que, profondément imprégnés de langage biblique, ils assimilèrent leur entreprise à la traversée du désert des Israélites, à une errand into the wilderness qui faisait d’eux des envoyés ou messagers dans la nature sauvage, symbole de la mise à l’épreuve qui devait permettre de recouvrer la pureté de la foi. La nature était ainsi fermement encadrée dans un paradigme providentialiste qui suffisait à lui donner sens. Dans cette perspective, elle apparaissait comme un lieu sauvage que l’homme avait pour mission de domestiquer et de rendre productif, par un processus de réforme ou d’amélioration (improvement) qui ferait de ces "solitudes hurlantes" (howling wilderness) la terre promise qu’était appelé à être le Nouveau Monde.

  • Plug computer
  • A plug computer is a small form factor server for use in the home or office. Compared to their PC-based counterparts, plug computers are lower cost, consume less power, often do not have a video card, and are intended to be powered up at all times
  • Suitable for running a media server, back-up services, file sharing and remote access functions such devices can be used as a bridge between in home protocols such as Digital Living Network Alliance (DLNA) & Server Message Block (SMB) and cloud based services.

Tor Project: Overview - 0 views

  • Overview
  • Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals use Tor to keep websites from tracking them and their family members, or to connect to news sites, instant messaging services, or the like when these are blocked by their local Internet providers. Tor's hidden services let users publish web sites and other services without needing to reveal the location of the site. Individuals also use Tor for socially sensitive communication: chat rooms and web forums for rape and abuse survivors, or people with illnesses.

Wikileaks : La guerre secrète - 0 views

  • Geoff Morrell, porte-parole du Pentagone prie Wikileaks de rendre les documents qu’il a en sa possession et d’effacer toutes les copies qu’il a pu en faire. Il ira jusqu’à menacer l’organisation en disant à présent que Julian Assange doit bien se comporter et qu’il doit rendre ce qu’il a volé, mais que s’il refuse, ils trouveront bien une autre alternative pour l’obliger à plier. Il n’y va pas dans la demi-mesure et c’est bien la première fois qu’un dirigeant menace quelqu’un en public, devant un parterre de journalistes.

How Apple and Amazon Security Flaws Led to My Epic Hacking | Gadget Lab | Wired.com - 0 views

  • In the space of one hour, my entire digital life was destroyed. First my Google account was taken over, then deleted. Next my Twitter account was compromised, and used as a platform to broadcast racist and homophobic messages. And worst of all, my AppleID account was broken into, and my hackers used it to remotely erase all of the data on my iPhone, iPad, and MacBook.

Distraits, les cyberdépendants? | Le Devoir - 0 views

  • «Nous exposons notre cerveau à cet environnement et nous lui demandons de faire des choses qui ne font peut-être pas partie d'une évolution normale, résumait il y a quelques semaines le neurologue américain Adam Gazzaley, de l'Université de Californie, dans les pages du New York Times.
  • le mythe de l'humain multitâche et hautement productif avec son iPhone en main qui lui permet de suivre les cours de la Bourse, de programmer sa télévision à distance, de gérer sa bibliothèque musicale, de tenir à jour son agenda, d'informer ses amis de ses déplacements tout en téléchargeant des livres d'histoires à lire à ses enfants le soir avant de se coucher.
  • La technologie tend à reconfigurer les connexions du cerveau, mais elle est aussi contre-productive lorsqu'utilisée avec excès, estiment les chercheurs, et le fléau touche certainement la majorité des ménages dans les sociétés hautement numériques

  • The copter itself is organised around the main CPU. The job of this CPU is to acquire the physical measurement given by the gyroscopes and accelerometers and to control the motors to keep the copter stable. This is done by a regulation loop which controls the motors speed 250 times per second. The radio communication has a pretty low bandwidth and is used to send commands to the copter and receive telemetry data from it. The CPU program can be updated by radio.
  • The computer runs control and telemetry programs. The control program reads the input from a game-pad and sends control commands to the copter. We also have programs that can configure the copter regulation parameters and log the measurements in order to make easier to tune the regulation. All the development is done on Windows and Linux. Indeed we are 3 to work on this project, two of us work on Linux and one is mainly on Windows. Using FLOSS permit to handle that in a very effective way. We are mainly using the GCC compiler from CodeSourcery for the copter program compilation, GNU Make for the project build, Mercurial for the source control, and python/pyusb for the communication with the copter. All these softwares works seamlessly on both Linux and Windows and made the project pretty easy to handle. The distance between the motors (horizontally and vertically) is around 8 cm and the total weight is around 20 g.

  • The top of the board contains the sensors and the control/communication electronic: The JTAG/Serial connector permit to program the processor and to communicate debug messages. The Main CPU is a STM32 Cortex-M3. It is clocked at 64MHz from the internal oscillator. The 2 Axis X-Y Gyro is an invensense IDG500. It has an analog output and thus is connected to the CPU analog to digital converters. The 1 Axis Z gyro is an invensense ISZ500. As the X-Y gyro this is an analog chip connected to the CPU analog to digital converters. The 2.4GHz Radio is based on a nRF24L01+ chip from Nordic Semiconductor. It is actually a breakout board sold by SparkFun. The radio is connected to the CPU via a SPI port. The 3 Axis Accelerometer is a SMB380 from Bosch. It is connected to the CPU via an I²C bus.
  • Here nothing particular, except that the little battery is taped on the bottom of the copter. The battery comes from a Silverlit x-twin plane and actually permit 4.5min of flight time.
  • Under the battery we mostly have power supply and the “power” electronics: The charge connector accepts 5V and permits to charge the battery The power switch permits to power the copter either from the charge connector or from the battery. The 5V step-up permits to increase the power voltage from the 3~4V coming from the battery to 5V. The two 3.3V linear regulators, reduces the 5V to power the copter electronic. The digital and analog 3.3V are generated independently. This was made to reduce the noise on the analog components (here it is the two gyros, a quite critical part). Finally at the four sides we have the motors transistors. The power for the motors pass on the top and bottom of the part of PCB that hold the motors. It can be noted that we also have the battery charging chip just at the right of the 3.3V regulators. It is a classical MAX1555 and is working pretty well. The idea with the step-up was to get a more stable voltage when the battery is depleted and also to remove some of the noise coming from the motor electonic. Anyway, this boars is capable to work without by using 2.8V linear regulators instead. So most likely the step-up will be excluded on the next version and we also plan to integrate the radio on board. The motors and propellers are taken from a Silverlit X-twin plane. They are powered by the battery voltage.
  • The copter is controlled via a python program running on the PC. A Playstation bluetooth gamepad is used to pilote it.
