Microsoft Grabs No-IP Websites Police embracing tech that predicts crimes New technology allows police to predict crime before it happens, but some agencies can't afford the software. Predictive analytic software PredPol anticipates future crime based upon past activity. The program was adapted from similar software meant to predict earthquake aftershocks.Many police stations still use obsolete technology due to small budgets and aversion to change.Even so, police depend heavily upon social media to solve crimes. (CNN) -- For something that predicts the future, the software is deceptively simple looking. A map of a city is marked up with small red squares, each indicating a 500-by-500-foot zone where crimes are likely to take place next. The program is called PredPol, and it calculates its forecasts based on times and locations of previous crimes, combined with sociological information about criminal behavior and patterns. PredPol's system features a map of a city marked with red squares to show zones where crimes are likely to occur.

Mosaically ® - Photo Mosaic Creator (Free & Online) Neutralité : le CSA milite pour utilisation préférentielle de la bande passante Le CSA, pour pousser les acteurs de type Netflix à investir en France, compte agiter une carotte de taille : avantager ceux qui se plieront à ses règles. Parmi les avantages, une bande passante plus importante sera notamment proposée. Une mise à mal de la neutralité du Net dont est bien conscient Olivier Schrameck, le président du Conseil Supérieur de l'Audiovisuel. Olivier Schrameck « Mais encore faut-il que le conventionnement soit suffisamment attractif » Lors de son audition devant la Commission des affaires européennes de l’Assemblée nationale la semaine dernière, Olivier Schrameck, président du CSA, a notamment abordé la question polémique de la mise à mal de la neutralité du Net. « Notre idée, c'est qu'un certain nombre d'acteurs, extra-Européens ou même Européens qui ne soient pas Français, sont susceptibles de s'engager dans un mécanisme de conventionnement. « Une utilisation préférentielle d'une partie de la bande passante »

Blogs You've seen the word, you've seen the web sites and you may even have one. But have you ever wondered: What's the big deal about blogs? To make sense of blogs, you have to think about the news and who makes it. We'll look at news in the 20th vs. the 21st century to make our point. In the 20th century, the news was produced professionally. The 21st century marked the point where news became both professional and personal. As blogs became popular, they created millions of news sources and gave everyone an audience for their own version of news. With a blog...A business owner can share news about his business A mother can share news about her family Or a sport star can share news with fans These people are all "bloggers". How did this happen? Blogs are websites that are organized by blog posts - these are individual news stories, like articles in the paper. Also, Each blog post can become a discussion through comments left by readers. Speaking of relationships, bloggers often work together.

Comment l’État a participé à la création de l’internet Par Steve Fritzinger, depuis les États-Unis. Dans son désormais célèbre discours « You didn’t build that » [Vous n’avez pas construit ça, NDT], le président Obama a dit : « L’internet n’a pas été inventé tout seul. La recherche d’État a créé l’internet pour que toutes les entreprises puissent gagner de l’argent avec l’internet ». L’affirmation d’Obama correspond à l’histoire conventionnelle de l’internet. Comme tout bon mythe fondateur, cette histoire contient une part de vérité. L’idée d’une interconnexion de réseaux [internetworking, NDT] a été proposée pour la première fois au début des années 60 par le chercheur en informatique J. Dans une publication scientifique datée de 1962, Licklider a décrit un « réseau de réseaux » qu’il a appelé « réseau intergalactique d’ordinateurs ». Licklider a amené avec lui l’idée d’une interconnexion de réseaux lorsqu’il a rejoint l’ARPA en 1962. En 1968, l’ARPA a financé le premier réseau à paquets commutés à quatre nœuds. I, Internet

Web Search Strategies The Web may seem like a vast ocean when it comes to finding something you need. Thankfully, search engines can help turn oceans of information into small pools that make finding information easier. Before we dive in, let’s talk a bit about how search works on the Web. Search engines go out and try to account for every word on every webpage. All this information is then organized for easy reference. When you search for a word, the search engine finds all the pages where the word appears, and displays them in the search results. The problem is that there are often too many results. Say you’re looking for a specific kind of fish, and these represent all the websites on the Web. Try to imagine the exact fish and describe it in the search box. But to be a smart searcher, you should know some basic shortcuts. Here’s another shortcut.

How Government Did (and Didn't) Invent the Internet Last night, I happened across an article by Slate technology scribe Farhad Manjoo. He was responding to an opinion piece in the Wall Street Journal by the Journal’s former publisher Gordon Crovitz. And when Manjoo explained just what Crovitz was opining about, I felt my jaw drop to the floor as if I were a character in a 1940s cartoon. Crovitz, apparently riled up over Barack Obama’s “you didn’t build that” kerfuffle, has an example of something that the government is widely misperceived to have built: the Internet. He actually says, “It’s an urban legend that the government launched the Internet.” As Manjoo points out, Crovitz’s argument — which rests largely on his contention that the Internet was really created at Xerox’s legendary PARC lab — is bizarrely, definitively false. Also factual: DARPA was where Robert Kahn and Vint Cerf invented TCP/IP, the plumbing that makes the Internet possible. (Crovitz, incidentally, credits Berners-Lee for the hyperlink.

World Wide Web Have you ever wondered, when you visit a website, where those words and images come from? These days, as long as we have an Internet connection, using the Web is pretty easy. We can visit billions of pages on things from pet alligators to the weather in Holland. To help figure out how it works, let’s pretend we can get really small, follow the wires and explore what makes the Web work. In order to get to the Web, we need a connection from our home or business to the rest of the online world. This usually happens through the phone or cable lines, or even satellite. If we could see the connection, the information coming through it would look like little packets of code. For this, we use a web browser. It’s called a “server.” We do this with web addresses. The reason we call it a “web” is that all the servers are connected. Web pages use shortcuts or “links” – words and images we can click, that direct us to page after page. Together, this system makes up the World Wide Web.

Did Al Gore Claim He Invented the Internet? Claim: Vice-President Al Gore claimed during a news interview that he "invented" the Internet. Origins: Despite the derisive references that continue even today, former Vice-President Al Gore never claimed that he "invented" the Internet, nor did he say anything that could reasonably be interpreted that way. The "Al Gore said he 'invented' the Internet" put-downs were misleading, out-of-context distortions of something he said during an interview with Wolf Blitzer on CNN's "Late Edition" program on 1999. When asked to describe what distinguished him from his challenger for the Democratic presidential nomination, Senator Bill Bradley of New Jersey, Gore replied (in part): During my service in the United States Congress, I took the initiative in creating the Internet. Al Gore was the first political leader to recognize the importance of the Internet and to promote and support its development. No one person or even small group of persons exclusively "invented" the Internet.
