The system is available only for Windows users (Windows XP or Windows 2000) with internet browser explorer or firefox, and uses a set of several techniques already known, the most important of which is essentially the same that uses the famous transparent proxyTelephone: After installing the program, every time your browser asks for a new page, the first thing to do is to check if it is available on a google server. Logically for google, it is rare that it does not have a copy in its cache, in which case, google checks that the version that has stored is still the last available, and if so, it sends it to you. If not, update your cache and send you the updated version.
An additional acceleration mechanism is the advanced discharge ( prefetch, In free translation) of links: while you read the page you just downloaded, the program analyzes if there are other links in the same, and downloading them in the background, so if you finally click on any of those links, You already have the content on your computer and it shows instantly.
The disadvantages of the first system are similar to those that caused the telephone proxy was not very well received: the telephone proxy in some cases did not show the latest version of the page, and in other cases could not even access the Page since the destination server interpreted all the requests that came from the proxy as a single user, prohibiting access to it (this we have seen, for example, in the Google news service or slashdot).
On the other hand there is no gain in any case, but only if there are several conditions: that there is a cache copy on the google server and that the google server is closer and faster than the destination server. In any other case, the accelerator will really only add an unnecessary process to our connection.
The pre-downloading system has the disadvantage that it can pre-download pages uselessly, as happens if you then decide not to follow any link of the downloaded page, causing a useless consumption of bandwidth. In any case, at least in the way in which prefetching was introduced by Mozilla years ago, only this forward download occurs if the code of the link so foresees, So in principle in the immense majority of cases there will be no prefetching any.

Looking for a name for the European XP
Windows webadmin escribió “Como parte del cumplimiento de una serie de sanciones impuestas por la UE, Microsoft lanzará próximamente en Europa una nueva versión de su sistema operativo XP, cuya novedad es que no incluirá el Windows Media Player.
La comisión ha rechazado el nombre propuesto por Microsoft para esta versión :Windows XP Reduced Media Edition, por considerar que se ha escogido un nombre conscientemente poco atractivo. Microsoft promete buscar un nombre alternativo …
Como nota adicional, este sistema operativo tendrá el mismo coste que las versiones ya existentes.”

A virus that searches Google for its victims
security The recent virus Santy.A uses an ingenious system of propagation to jump from web server to web server. From an infected machine makes a query to Google to locate web pages that use an old version of the well-known phpBB forum, installed on thousands of servers. With the list of potential victims, it addresses a request to each of them, taking advantage of an old vulnerability, which allows you to upload files and make a message appear on the page announcing the “conquest”. Each infected computer restarts the process.
This virus only spreads between web servers with pages that use this old version of phpBB; Does not affect individuals nor does it involve any risk of visiting an ‘infected site’.
