As you can see, it was very exciting to download information from the Internet: this was a proper activity of the environment scientific, because it had to deal with protocols, codes, file names, folders and addresses "url", in an era where there was no mouse.
Alternatively, a company called CompuServe offered a more simple to use shell. The system worked well: they focused information on their servers, and the user through a simple interface like this
sailed for sub categories to find what I wanted, for example, a picture with Escherichia coli.
Much better! But some problems remained unresolved:
- Compuserve was paid - u $ s 60/month, ISP not included.
- The photo of the bacteria was not available "freely." Was hosted on Compuserve. However
Compuserve was a great deal for their creators. And when the word business, you see the big fly. Microsoft launched a similar service - The Microsoft Network.
delusions of conquest in the M $ world, information would be contained on their servers. People would pay for publishing and retrieving information in a simple way, the way Compuserve.
But here comes Tim Berners Lee, the scientist who invented HTML, if you wrote the information in the form of labels, could abstract the complicated code and address that linked images, text and servers together, and present the dish all armed. HTML is a presentation language easy to learn, and unlike the shell sessions, does not strictly require a programmer. The client user would only need a program called "browser" in the style of the old Gopher, which was designed for Mosaic.

Wonderful! However there were still three major problems:
- The operating system, Unix.
- The hardware where to run Unix (Unix is \u200b\u200bnot yet running at extremely slow PC).
- The Web page server program: eg Sun Web Server Netscape
This is really when Bill Gates Gates misses the biggest deal of all time. In comparison, the licenses of all your trash with windows you are a miserable part of what really could have checked: Microsoft had with it was cheaper for users to access and publish on The Microsoft Network. Each person on the planet would have to pay some $ s 50, subject to monopoly, and without Internet access provider, to connect to the Internet that sort of control. The dream of the Matrix, say.
But he pulled down five situations the project.
Rise of the Hackers
1. Intel, AMD then, draw the 80386 home market. Unlike the other processors (8086, 8088 XT, 80286), this is the first able to meet the primary requirement of Unix: preemptive multitasking. Of course, any company that sold Unix operating system ported to this processor, they also profited by selling hardware. 2. Richard Stallman created the GNU utilities, a set of tools that are equal to the ground from any Unix. A giant work up to and including a C compiler, GCC.
3. Linus Torvalds kernel combines the GNU / Linux, a clone of Unix open, capable of simulating all Unix tasks on a PC 386!
4. In the legendary University of Berkeley, the mother of TCP / IP, the first Unix, and even the SETI project, there is the first free BSD Unix.
5. Inspired by the same hacker university spirit is released Apache web server for Unix. The availability of source code, compiled with GCC on these two cousins, GNU / Linux and FreeBSD.
These "cousins" hippies of Unix, like a car ugly Russian. But just how reliable, off-road, hard and very stable. The ease of use no matter the Unix hackers and exiles. They are comfortable with the command line. Over time, Miguel de Icaza (Gnome) and the people of Trolltech (KDE) will improve interfaces. An army of geeks built hundreds of free tools that replace Unix.
The Microsoft Network and CompuServe skid and for 98 years are history. Now ordinary users can access the "Web", a mask of Internet easy to use, it runs even on that pyramid called Windows error, which is accepted in the 90 for its ease of use, and compatibility with MSDOS The proto operating system used from 1982 to 1995, before 80386.
Microsoft, at all costs trying to make money with the new spirit of freedom. If you can not create your website, try to enslave the users of the other web. Makes its own web server (IIS), and a web browser labeled "not free", called Explorer. Comes
year 96. At Sun Microsystems react: they have lost the market for Unix servers and the Web. The only thing left is Netscape Navigator, and this is ignored by zombies users who use Windows Explorer 95. But many hackers working Sun. The business model of hackers going by the sale of service instead of product: Every time a product is not profitable, set him free. Thus benefit the community of free software, and Microsoft torpedo below the waterline.
Inspired by the cult text of "The Cathedral and the Bazaar" by Eric Raymond, Sun Microsystems released the source code of Netscape, that gives rise to the Mozilla Foundation. Later released StarOffice, which exploits to Openoffice.
The rest of the story is already visible: the hand of the penguins, the water buffalo (gnu) and the Indian, the web grows unhindered geometrically since 1998. Geeks only requires you to plug all those components for free.
Web, unlike Microsoft's proposal, free, is ignored, and nobody owns the information.
Discussion proposal:
This is a blow from which Microsoft will never be reset. I tell them is Windows, but who cares that Windows is the system most used OS on the computers? Nobody actually uses an operating system. Only enter information in an office. Then most of that information is transferred by email, ie is housed in the Sent folder of a remote Linux or in a cloud of penguins: when using Google, Yahoo, Facebook, Twitter or any other web site, below we are using Linux, or its free cousin, FreeBSD. If you think that almost any document has been created for the purpose of being sent or published, we find that almost all of our files can be recovered / backup entering a remote tag. There also exists in hard drives, also compatible with Linux. If the user insists use Windows, the better for those Arabs who live technical ss: per unnna moddica thumma, hazamos zu backup horendo Zeven, baratitu cobbramo. We agree that if patients on the advice of doctors, they will eventually starve.
Microsoft has been relegated to become a sad spectators, to provide a mask idiot (Explorer) to the true information, guarded by Internet, and for its strong pillars: free software and geeks.
Finishing the first decade of XXI century, the hackers are united in corporate form. And by free software have created very solid companies like Google, Facebook, Twitter, Apis open, returning to the middle of some of his research: Google Maps, Cassandra, Go, or at least employing people with a collaborative spirit.
". NET? Windows Servers "? Mere business solutions for computer pergueñadas just more awake than the average user. Simple business solutions, domestic, SME oversized, far from the real revolution: the spirit of the hive, the virtual space where the human race communicates and develops into a new hive mind.
Goodbye
hegemony.
