Actuality of Social Networks




Social networking is a hot topic. Ordinary Internet users take advantage of networks when they turn to well-known websites like MySpace and Friendster to link up with other people. But more serious interest in social networks can be found among academics, consultants and corporations seeking to deepen their knowledge of how companies operate; how employees and board members interact; how key employees can be identified; and how relationships can be better understood to improve productivity and the dissemination of ideas.

Technically, social network research is an offshoot of graph theory in mathematics. Graphs -- a set of dots connected by links -- are used to map relationships. At its most basic, research on social networks underscores the veracity of some of the truisms one hears all the time: "It's a small world." "It's not what you know, it's who you know." "Birds of a feather flock together."

DRM - Digital Rights Management


Digital Rights Management is an umbrella term that refers to any of several technologies used by publishers or copyright owners to control access to and usage of digital data or hardware, and to restrictions associated with a specific instance of a digital work or device. The term is often confused with copy protection and technical protection measures; these two terms refer to technologies that control or restrict the use and access of digital content on electronic devices with such technologies installed, acting as components of a DRM design.

With what the DRM is used?
The DRM results from a very simple report: the numerical supports are particularly favourable with the copy: it is enough to a click of mouse to duplicate the contents of a file on another support. From where interest of crypter these files in native mode, so that one can read only with one adapted and made safe reader.

Which are the media concerned?
All the media are concerned as from the moment when they can be diffused in numerical form. The sound is today the first market of the DRM.
Protection of the numerical rights has includes other types of files: scientific contracts, documents and software, even if they are not to be strictly accurate media but rather productions entering under cover of the intellectual property.

Does the DRM change the economic models of diffusion?
The DRM offers a control much narrower and skeletal of the diffusion of the contents. It is now possible of personaliser in detail the diffusion of each marketed file: how much time could it be copied from another support, how much time could it be read, during how many days it will remain accessible, etc.... The DRM is not fixed: other models of diffusion remain to be imagined, the only limit being the degree of enthusiasm of general public for these new processes, which are always likely to hustle its practices, and to fail to allure them.

Web Neutrality debate

In "Net ignorance of the Christian Coalition," Armey conveniently fails to mention that Net neutrality was the law on the Internet until 2005. The dramatic expansion and innovation that he lauds existed and was made possible because the law prior to 2005 prohibited Internet service providers and other providers from erecting toll booths on the information superhighway.

The Federal Communications Commission and the Supreme Court effectively abolished the Net neutrality requirement just last year. Instead of dramatically expanding federal regulation of the Internet, a Net neutrality requirement would be restoring regulation that has existed for most of the life of the Internet.
Armey's argument that secure private-property rights and consumer choice will preserve free speech on the Internet similarly ignores inconvenient facts.

Armey's argument that secure private-property rights and consumer choice will preserve free speech on the Internet similarly ignores inconvenient facts. Most consumers have few, if any, real choices regarding their broadband Internet providers. As these companies consolidate and move to secure their own "private property rights," consumers will have even fewer choices.

The result is that fewer and fewer companies will have more and more control over what consumers see and do on the Internet. If the consumer does not like the services provided by his ISP, he or she will essentially have two choices: Take it or leave it. In a nutshell, this is Congressman Armey's philosophy of the free market.

Finally, Armey asks why the Christian Coalition would support a federal law forcing ISPs to treat pornography the same as family-friendly content. Protection of free speech includes speech with which we disagree. If ISPs are allowed to become the gatekeepers of the Internet, everyone's speech is at risk. Regardless of whether the ISP disagrees with the speech or merely finds that some speech is not as profitable as others, the end result is that the marketplace of ideas will be radically diminished.

We are already seeing ISPs controlling speech with which they disagree. For example, Time Warner's AOL blocked all e-mails that mentioned "www.dearaol.com", an advocacy campaign opposing the company's pay-to-send e-mail scheme. BellSouth recently blocked its customers' access to MySpace.com in Tennessee and Florida. Net discrimination is real, it is occurring now, and is only going to get worse.
Protection of free speech includes speech with which we disagree. If ISPs are allowed to become the gatekeepers of the Internet, everyone's speech is at risk.

Anyone who feels that Net neutrality will stifle innovation on the Internet isn't paying attention to history.

For example, before the government broke up the company, AT&T controlled all telephone access. You could not buy a telephone--you had to rent one from AT&T. You could not hook up any non-AT&T-approved device to the telephone lines, including answering machines and modems. And, of course, there was a hefty premium to pay if you wanted to use any AT&T devices. There was no real competition and thus no incentive to innovate.

It was only after the company was dismantled, and there was increased competition, that the dramatic innovation we have seen in the last 25 years came about. Now that AT&T has started gobbling up much of its competition, it is starting to yearn for its glory days of absolute control over its network.

On the Internet today, no one is getting a free ride. You pay for your Internet access to your ISP. Google and Yahoo pay huge amounts of money because their sites use more bandwidth than the average blog or Web site. Net neutrality won't change that. What it does do is stop network operators from playing favorites and deciding that the service quality a content provider gets depends on the business arrangement it makes with the ISP.


Suppose Google and Yahoo continue to pay large amounts of money for their Internet access, but AT&T works out a deal with Google. Users who wish to use Yahoo for a search engine get routed to Google instead. Or else, searches of Yahoo are slowed down so much that users become frustrated and switch to Google. AT&T gets to make more money, and the user's choices become more limited. Or you decide to visit your favorite blog. Since the blogger didn't pay enough to the ISP for preferential treatment, you can go have lunch and dinner while the site loads on your computer, if it loads at all.

The Supreme Court has recognized that through the use of the Internet, anyone can be a town crier or pamphleteer "with a voice that resonates farther than it could from any soapbox." It is a unique medium for expression.

But the Internet did not get where it is by letting gatekeepers determine what information reaches its destination or slowing the information from competitors. If the Internet is to be preserved as a forum for speech and innovation, Congress must reinstate the requirement of Net neutrality.

New way on the web...

With web 2.0, Internet is a new platform restful about a lot of tolls knowing for a few years.

DoubleClick
, it was Web 1.0 ; Google AdSense, it’s Web 2.0. Ofoto, it was Web 1.0 ; Flickr, it’s Web 2.0

Web 2.0 is the appropriation by the developers Web of old technologies from five to ten years to bring a different ergonomics to their users: if it is a revolution, it is a revolution in the use of technologies and not a revolution of technologies themselves.

What's a "podcast" ?


A PODCAST is a contraction between two concepts : the ipod and the broadcasting.
It's a multimedia file distributed over the Internet. A podcast is genraly free and you can download a podcast in all sites which propose that, or you have platerform for that like Itunes.

The last podcast that I have download is the videoclip of Kamini, a "singer" that he haad a big successfull with the transmission in Internet. Nowadays, he is like a star !

But podcast isn't only for the music's world! It's for all subjects : cinema, books, amaters video, tutorials... etc.
It's very practice when yu van't transporte your Mac or PC, you have in your Ipod, your own tuturial for improve your level in Photoshop for exemple! The Team of "Frenchstudio" is very nice, I think.
