Video Killed the Radio Star. Now What? If you’re old enough to remember the Hypercolor T-shirt, you may also vaguely recall a time when you had to rush home on a Thursday evening to make sure you caught the latest “Seinfeld” episode on the air. Sure, you could set your VCR if you knew you were going to hit traffic; but how many of us even had those ancient contraptions by the end of the millennium — much less knew how to work it? Besides, it wasn’t long after the final episode of “Seinfeld” — only one year, in fact — that TiVo launched, completely changing the way we consumed our media, making it ad-free and on demand. As we got used to the idea of saving our favorite shows to watch on our own time, real-time viewing of a TV show became less and less relevant. Now, watching a show during its actual broadcast time — if you even know the air time; I bet you don’t — is only applicable for mega-fans, news shows, live sports and that latest “Downton Abbey” episode you don’t want spoiled by Twitter.

Visite de Google Data centers TB Back When you're on a Google website (like right now), you're accessing one of the most powerful server networks in the known Universe. But what does that actually look like? Here's your chance to see inside what we're calling the physical Internet. Who's behind the doors of the vast global web we call the Internet? What makes a good hometown for the Web? Google has been working for years to optimize our data center designs in order to minimize our environmental footprint. At our data center in Pryor, Oklahoma, we've built strong ties with the Cherokee community. One of the reasons Google chose the city of Lenoir, North Carolina is its roots as a factory town in the furniture industry. Our data center in Belgium is notable for being the first to operate without water chillers. Here among Oregon’s rolling hills, snow-capped peaks and brisk Columbia River, we make Google products and services available to the entire world.

Low-Cost Tools That Every Techie Needs It’s been ten years since I took my first IT job, and in that time I’ve collected a bunch of tools that have proved invaluable to me in resolving issues with computers, hard disk drives, printers and other corporate hardware. While I work purely freelance these days, I still maintain a collection of devices and gadgets that can be used to assist with quickly resolving problems that might arise. By bringing you this list of must-have hardware, I hope to be able to demonstrate that not only is the role of the successful desktop support technician 50% knowledge, 30% personality and 20% efficiency, but that these tools are affordable. The Basics What do you keep in your toolbox? USB stick, 4GB or higher capacity.USB SD card adaptor (can be bought very cheaply).Ethernet Cable Crimping Tool.Torx screwdrivers. Hard Disk Recovery Recovering a hard disk can be tricky enough without having to waste time connecting the device up to a working PC or one that is more suitable for data recovery.

Block Chain 2.0: The Renaissance of Money From 2008 to date, no other technology has been the subject of such fervent debate. Irrespective of your opinion, the rise in popularity of cryptocurrencies cannot be ignored. Today, there are a number of billion dollar businesses that accept Bitcoin as a form of payment. Elements of Protocol Commonality: TCP/IP and the Block Chain In December 1974, Vint Cerf and Robert Kahn designed something revolutionary: the TCP/IP Internet network protocol. A protocol is like manners. In a similar way, TCP/IP was first developed as a way for any computer to connect and communicate with the ARPANET. But the base technologies have remained unchanged. Leveraging on this mode of functioning, Tim Berners-Lee created the Hyper Text Transfer Protocol or HTTP, which became a way for Web browsers to communicate with Web Servers. Just as the TCP/IP-based internet led to a revolution in the way businesses functioned, the Block Chain protocol is repeating the same process all over again. Micropayments

NASA's experimental plane wing has 18 propellers | The Verge NASA is working to make a more efficient, electric-powered plane, and the proposed wings for it look like something out of a dream. 18 small engines sit atop the 31-foot wingspan, and work together to lift and propel the plane forward. The wings are part of NASA's Leading Edge Asynchronous Propellers Technology (LEAPTech) project. The propellers are all electric, powered by lithium iron phosphate batteries. Each propeller can be operated independently at various speeds to optimize power, with all 18 engines providing lift during takeoff. If this all sounds too good to be true, that's because it is — for now. Researchers hope once the LEAPTech wing is improved, it can be used to create a new environmentally and economically efficient X-plane.

Utilisation de tracert (accès à france 2) Image courtesy of jscreationzs at Je vous rappelle les 4 grandes catégories d’opérateurs sur Internet, des fournisseurs d’accès Internet, (exemple : Orange, Free, …) des fournisseurs de contenus et de services, (exemple Google, Youtube, France télévision, …) des CDN (Content Delivery Network) : des sites qui mettent à disposition du contenu, des opérateurs de transit IP (c’est ceux qui vont permettre de faire le lien entre les différents fournisseurs). Je vais vous montrer une petite manipulation qui permet de voir le rôle de chacun, et leur contribution lorsque que vous surfez sur Internet. Nous allons voir un aspect important d’Internet, les CDN. Pour cela, nous allons utiliser la commande « Tracert ». pour démarrer nous allons voir la route pour accéder aux serveurs de « » puis nous allons examiner la route vers le « ».

Networking & Server software / hardware for Windows 2003, 2000, NT & Linux - Digital transformation: Expect massive job cuts, says Gartner senior VP Don’t bother protecting jobs that are going to go away anywayExplosive growth in sensor deployments in the upcoming decade THE Internet of Things (IoT) has been one of the key drivers for digital transformation, and Gartner Inc senior vice president and analyst Dale Kutnick (pic above) predicts that a rapid spread of physical sensors will take place on a global scale in the next five to 10 years. However, this type of automation will also lead to massive job cuts, he warned. In the next 25 years, there are going to be much fewer jobs in the global market, he told a media briefing in Kuala Lumpur on May 31. “Agriculture is already moving towards remote control vehicles, whether it’s for harvesting or planting. So it’s pretty autonomous, meaning fewer farmers will be needed. Speaking on the prospect of digital businesses in Malaysia, Kutnick said it is “down to the industrial policy of the country.”
