Virgin Galactic SpacePlane - EADS ASTRIUM Un voyage dans l’espace. C’est désormais possible, et bientôt, sans doute, relativement accessible. Mais en construisant son Spaceplane, Airbus Defence and Space ne mise pas seulement sur le développement du tourisme spatial. Car les possibilités de cet avion dépassent très largement la simple balade extra-terrestre. Ses concepteurs ont d’ores et déjà imaginé d’autres missions et perspectives dans le futur. Il faut dire que, pour étudier la mécanique des fluides, la biologie, la physiologie humaine, la combustion, ou encore la physique fondamentale, les chercheurs ont parfois besoin de recréer des conditions d’apesanteur. Principal écueil, cette phase en apesanteur se limite à 20 secondes et doit se répéter de nombreuses fois pour une expérimentation de quelques minutes. Découvrez en cliquant ci-dessous l'animation présentant les différentes phases du SpacePlane : Autre objectif : la mise en orbite de petits satellites. Video: Voler jusqu’à l’apesanteur

Hubble Captures Time-Lapse Videos Of Stars Being Born : The Picture Show The birth of star is just as traumatic as the birth of a person, only on a much larger scale. For years, astronomers have known that newly formed stars fire powerful beams of gas into space called "protostellar jets." Because almost every young star forms these jets, astronomers have been desperate to get a better understanding of their evolution and their role in the star formation process. Until recently, however, astronomers had to be content with simple snapshots of the infant stars and their jets — not a great help when it comes to understanding how something moves. Now, using pictures taken by the Hubble Space Telescope across more than a decade, my colleagues and I have been able to create movies of the jets. Pat Hartigan of Rice University and I (along with other collaborators) produced movies that provide a new perspective on protostellar jets as they blast away from their newly formed stars.

Stellarium FreeNX FreeNX is a system that allows you to access your desktop from another machine over the Internet. You can use this to login graphically to your desktop from a remote location. One example of its use would be to have a FreeNX server set up on your home computer, and graphically logging in to the home computer from your work computer, using a FreeNX client. It's Open Source, secure (SSH based), fast and versatile! License: GPL Note: Running FreeNX as server on Ubuntu with the free "NX Client for Windows" from NoMachine on a Windows workstation is working fine, except resuming sessions. Terminology The Server is the computer you want to connect to. The Client is the computer from which you want to be able to access the Server. Before installing FreeNX server make sure you have SSH set up and is working. We will be installing the FreeNX server on the Server machine, i.e., the machine that you want to access remotely. FreeNX is not included in Ubuntu, so we'll add it from the FreeNX Team PPA.

i-Tourisme | L'innovation technologique au service du tourisme i-tourisme : Le paysage du transport aérien est en train de se redéfinir. L’accroissement des ventes additionnelles avec par exemple les accès au Lounge ou les sièges payants est spectaculaire. Les compagnies low-cost intègrent, les unes après les autres, les GDS. Le dernier exemple en date est celui de Ryanair qui a annoncé avoir contracté un accord, en priorité avec vous, alors qu’il jurait ne jamais vouloir passer par le circuit professionnel. Pourquoi toutes ces évolutions et à qui profitent-elles ? Emmanuel Bourgeat : “A tous : aux compagnies aériennes low-cost et dites « traditionnelles » d’une part, qui voient ainsi la possibilité d’exposer l’exhaustivité de leur offre quel que soit le canal de distribution emprunté par le voyageur. Pour rappel : mondialement, plus des 75% de la distribution passent par le canal de la distribution traditionnelle. Le plus important demeure, à mon sens, que l’agence se retrouve à nouveau au centre de l’offre. i-tourisme : Ce sera le cas avec Ryanair ?

HTG Explains: The Linux Directory Structure Explained If you’re coming from Windows, the Linux file system structure can seem particularly alien. The C:\ drive and drive letters are gone, replaced by a / and cryptic-sounding directories, most of which have three letter names. The Filesystem Hierarchy Standard (FHS) defines the structure of file systems on Linux and other UNIX-like operating systems. However, Linux file systems also contain some directories that aren’t yet defined by the standard. / – The Root Directory Everything on your Linux system is located under the / directory, known as the root directory. /bin – Essential User Binaries The /bin directory contains the essential user binaries (programs) that must be present when the system is mounted in single-user mode. /boot – Static Boot Files The /boot directory contains the files needed to boot the system – for example, the GRUB boot loader’s files and your Linux kernels are stored here. /cdrom – Historical Mount Point for CD-ROMs /dev – Device Files /etc – Configuration Files

New cool list of Linux must-have programs Update: A new, up-to-date collection is available. Please take a look! It's been approximately two years since I've written the first article, A (cool) list of Linux tools. The article proved quite popular with my audience, as it allowed Linux users, new converts in particular, a quick taste of some of the more useful programs available for Linux platforms, across a range of categories. Since, a lot has changed. Changes from the last time Like the last time, the programs will be sorted by categories. Games I will not be listing games here. Users' recommendations Likewise, there's a users' recommendation sub-section, so you can send me your suggestions and ideas. Table of Contents: Backup software File backup software Unison Unison is a simple, lightweight backup program. TimeVault TimeVault is a snapshot software, which, when activated will create copies of all files and folders that change, retained a detailed archive of all revisions.
