cURL – Split a file and download simultaneously from multiple locations
cURL is a command line tool for transferring files with URL syntax. It supports FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS and FILE protocols. With cURL, you can stop a download and then at a later stage, resume from where you left off. This is a great boon for downloading large files. Here is a tip to split a large file and download it simultaneously from multiple locations. In this case, you can use curl to download different parts of the ISO image from alternate servers thus circumventing the throttling issue. As an example, I will show you how to download Ubuntu 8.10 Linux distribution ISO using curl and the above mentioned trick. Step One Identify the download mirrors from the Ubuntu website. Where url1, url2, url3 and url4 are variables which are associated with the corresponding full paths of the Ubuntu ISO file. Step Two We are going to split the file ubuntu-8.10-desktop-i386.iso into 4 parts, with 3 parts of 200 MB and the rest making up the 4th part.

Crawling, Mining, Scraping
Au commencement était le "crawling". L'exploration. La recherche d'informations. Celle menée par les "crawlers" des moteurs de recherche. Du scraping au "raping" (viol) il n'y a pas loin. Cette trilogie technologique (Crawling => Mining => Scraping) doit pour être bien comprise, être mise en relation avec les trois "temps" de ma petite théorie de la dérive des continents documentaires (voir ce billet pour le petit schéma explicatif). <Update du soir>Les choses vont décidemment trop vite, heureusement, les commentateurs de ce blog suivent l'actualité en temps réel - merci Candide :-) Donc Plaxo (le "scraper"), Facebook, mais aussi ...

Facebook, Google And Plaxo Join The DataPortability Workgroup
After publishing an invitation to Facebook to join the DataPortability Working Group January 4, we never thought that Facebook would accept it. Today changes everything you’ve ever thought about social-networking data and lock-in before, because today Facebook, Google and Plaxo have joined the DataPortability Workgroup. Google and Plaxo joining are a positive, however given that both have previously joined together for platforms such as OpenSocial it’s not that significant, but Facebook is another matter. On January 4 Michael sort of defended Facebook’s stance against Plaxo pulling data from Facebook on the grounds that “Facebook also has a very good reason for protecting email addresses – user privacy.” Today, by joining the DataPortability Working Group Facebook is embracing open standards and open access, and that is a huge fundamental change from its previous stance on being locked in to closed standards.

Guerre des données/1 – Facebook contre Plaxo
L'escarmouche qui vient d'opposer Plaxo et Facebook annonce une guerre dont nous sommes, comme toujours, le principal enjeu et, dont nous pourrions envisager de devenir les principaux combattants. Il s'agit, au fond, de savoir qui possède les données nous concernant, une question essentielle pour qui comprend que leur contrôle est source de pouvoir. Plaxo a mis au point un "importateur de données", un robot capable de "racler" (to scrape) des informations se trouvant sur d'autres sites et a demandé à plusieurs journalistes dont Robert Scoble, un des blogueurs les plus fameux, d'en faire l'essai sur Facebook. Détail technique qui a son importance, pour éviter une telle manip, Facebook révèle l'adresse courriel de ses membres sous forme d'image. C'est moins comique qu'on pourrait croire. Cette volonté de protéger nos données est louable mais les "amis" de Scoble étaient ravis de l'avoir dans leur réseau et l'échange d'infos est mutuel. A suivre… Signaler ce contenu comme inapproprié

What is Web Hosting? Web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet. A web host, or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed in the Internet. Websites are hosted, or stored, on special computers called servers. When Internet users want to view your website, all they need to do is type your website address or domain into their browser. Their computer will then connect to your server and your webpages will be delivered to them through the browser. Most hosting companies require that you own your domain in order to host with them. Here are some features you should be expecting from your hosting provider: If you decide to create and host your website with Website.com, in addition to access to the drag and drop site builder, you can get a custom domain, email addresses, and web hosting all bundled into one subscription.
