UCLA mathematicians discover rare prime number
UCLA mathematicians appear to have won the $100,000 prize from the Electronic Frontier Foundation for discovering the first verified Mersenne prime number with more than 10 million digits.
The winning number has a whopping 12,978,189 digits. The new number is only the 46th known Mersenne prime.
Prime numbers are those, like three, seven and 11, that are divisible only by themselves and one. Mersenne primes, named after the 17th century French mathematician Marin Mersenne, who discovered them, take the form 2P - 1, where P is also a prime number.
In the new UCLA prime, P = 43,112,609.
Thousands of people around the world have been participating in the Great Internet Mersenne Prime Search, or GIMPS, in which underused computing power is harnessed to perform the complex and tedious calculations needed to find and verify Mersenne primes.
Edson Smith and his UCLA colleagues harnessed the power of the 75 machines in the university's Program in Computing/Math Computer Lab, which is used by students for computer projects. Smith, a system administrator, realized that the lab was using only a fraction of its available CPU power. Rather than let it go to waste, he and his colleagues decided to use it for the GIMPS project.
The new Mersenne prime was discovered Aug. 23 on a Dell Optiplex 745 running Windows XP. The number was verified by a different computer system running a different algorithm.

Hackerare la Password dell Account di Windows Xp
Esistono in rete diverse guide che spiegano come craccare la password di un account di Windows Xp. In genere si cerca di scoprire la password dell account dell account administrator per poter sbloccare la connessione ad internet in ufficio o a scuola.
Le soluzioni sono diverse, per lo piu si tratta di impostare come boot primario il floppy drive o una penna usb, per poter far partire all avvio un programma per cambiare la password dell account utente. Oppure si agisce tramite una partizione parallela su cui e installato Linux, o ancora, e possibile usare il registro di sistema di Windows. Tutte quante comunque, soluzioni abbastanza scomode, e spesso impraticabili sui computer dell ufficio.
Sono rimasto davvero sorpreso dalla facilita con cui viene craccata la password di un account utente di Windows Xp in questo video.Ne consiglio a tutti la visione.

A third of Vista PCs downgraded to XP
Vista’s death march picked up some pace yesterday, after a metrics researcher revealed that nearly 35 per cent of PCs built to run the Windows operating system have been downgraded to XP.
In a survey of more than 3,000 computers, performance testing software developer Devil Mountain Software estimated that more than one in three new machines had either been downgraded by vendors such as Dell, or by customers once they bought the PC.
