The second chapter of Apple’s iPhone era is almost ready to begin, and it’s already clear that things will be a little different this time around.

Few people who pay even scant attention to the technology industry could claim to be shocked by the introduction of a faster iPhone earlier on Monday by Apple CEO Steve Jobs. Apple has sold 6 million iPhones since June 2007, Jobs said, and will likely sell a few more once the new model arrives on July 11 with a faster networking chip, GPS capabilities, and a software upgrade that’s an IT manager’s dream for a mobile device.

) IBM’s Roadrunner supercomputer has smashed the high-tech equivalent of the four-minute mile by breaking the lofty petaflop barrier.

IBM executives announced today that the company’s latest supercomputer - a hybrid system running AMD Opteron processors and Cell chips - sustained a speed of 1.026 quadrillion calculations per second. That’s about twice as fast as the next fastest supercomputer, IBM’s BlueGene/L, which is based at the Lawrence Livermore National Laboratory.

Revision3, the Internet television network behind popular shows like Diggnation, experienced a serious network failure over Memorial Day weekend. CEO Jim Louderback revealed today that the outage was caused by a massive denial of service attack that he says was perpetrated by MediaDefender, a file-sharing mitigation firm that gets paid by Big Content to disrupt peer-to-peer networks.

A SYN flood aimed at Revision3’s BitTorrent tracker clogged the company’s tubes and brought down all of its web services. The traffic logs indicated that the network was getting slammed by over 8,000 packets every second. Revision3 tracked the source of the packets and discovered that the attack originated from MediaDefender, at which point Louderback confronted the company’s executives. ArtistDirect CEO Dimitri Villard and MediaDefender vice president Ben Grodsky admitted to Louderback that they had been exploiting the lax security configuration of Revision3’s BitTorrent tracker and using it to conduct decoying operations, but they disavowed knowledge of the denial of service attack and claimed that their servers were only pinging Revision3 once every three hours.

Three of the world’s biggest chip players will cooperate with one another to develop silicon wafers to improve efficiency in semiconductor manufacturing.

Intel said yesterday that a migration from 300mm (12-inch) silicon wafers to 450mm (18-inch) would yield more than double the number of chips per wafer.

The trio hopes to have developed and tested required components, infrastructure and capability by 2012, when it plans to punch out a pilot line of chips based on the 450mm technology.
