Roundup: Nvidia takes a dive, Long Tail debate thrives, Google keeps source code

These graphics don’t compute: Nvidia stock fell 19 percent in after-hours trading today after the company disclosed some big problems with its second-quarter performance.

It blamed to heat problems on weak materials used to attach the chips to their packages in notebook computers. The company is also being hurt by poor demand across the globe, a delay in producing a next-generation chip set, and price cuts. Advanced Micro Devices also recently introduced a competitive graphics chip for the first time in more than a year. Analysts had expected Nvidia to report revenue of $1.1 billion, but the company now says its revenue range will be $875 million to $950 million.

Google wins a round against Viacom, users and privacy advocates lose: Google came out ahead when a federal judge ruled Wednesday that it doesn’t have to share source code for search functions on YouTube with Viacom. Viacom had asked for the code as part of its $1 billion copyright-infringement lawsuit against Google in 2007. Google won on the argument that its source code was a trade secret that can’t be disclosed without the risk of losing business. However, users lost out — the judge also granted Viacom’s motion that YouTube has to turn over the login information and and IP addresses of every viewer of every viewer.

IBM acquires mainframe rival PSI: One way to make a nasty antitrust problem go away is to acquire the folks who are complaining about you. IBM did just that as it said it would acquire Platform Solutions Inc. for an undisclosed price. PSI had been complaining to European Union regulators that IBM was behaving in an anti-competitive manner in the mainframe computing software market.
