Google discloses censorship demands to users


Google Inc. has set up a new tool to show where it's facing the most government pressure to censor material and turn over personal information about its users.
The country-by-country breakdown released Tuesday on Google's Web site marks the first time that the Internet search leader has provided such a detailed look at the censorship and data requests that it gets from regulators, courts and other government agencies. The figures, for the roughly 100 countries in which it operates, cover the final half of last year and will be updated every six months.
Google posted the numbers nearly a month after it began redirecting search requests to its China-based service. Those requests are now handled in Hong Kong rather than mainland China so Google wouldn't have to obey the country's Internet censorship laws. Google said details about the censorship demands it got while in mainland China still aren't being shared because the information is classified as a state secret.
In other countries, Google is making more extensive disclosures about censorship demands or other government requests to edit its search results. Google is also including demands to remove material from its other services, including the YouTube video site, although it is excluding removal requests related to allegations of copyright infringement, a recurring problem for YouTube.
Google is showing how often it honored those requests and spelling out which of its services were targeted.
In the United States, for instance, it received 123 requests to remove material from its services during the last half of 2009 and complied with 80 percent of them. Reasons include violations of Google's own policies regarding extreme violence, profanity and hate speech. More than 40 of those requests included a court order, Google said.
Google is providing a more limited snapshot of government requests for its users' personal information. The numbers are confined primarily to demands made as part of criminal cases, leaving out civil matters such as divorces. And Google isn't revealing how often it cooperated with those data demands.
The disclosure comes as more regulators and consumers watchdogs around the world are complaining that the company doesn't take people's privacy seriously enough. Google maintains that its users' privacy is one of the company's highest priorities. The company also notes that, in one instance, it has gone to court to prevent the U.S. Justice Department from getting broad lists of people's search requests.
Brazil's government peppered Google with the most requests during the six-month period covered. The company says that's largely because it operates a social network called Orkut. That service has attracted millions of users in Brazil and generates more taunting, derogatory language and other inflammatory material likely to trigger government requests and violate its own standards.

RB26DETT



The RB26DETT engine is a 2.6L Inline-6 engine manufactured by Nissan, for use primarily in the 1989-2002 Nissan Skyline GT-R. The RB26DETT engine block is made from cast iron, and the cylinder head is made from aluminium. The cylinder head contains 24 valves (4 valves per cylinder), and uses a dual overhead camshaft setup. The intake of the RB26DETT varies from other RB-series motors in that it has six individual throttle bodies instead of a single throttle body. The engine also uses a parallel twin turbo system. The turbo system is arranged so that the front turbo is powered by the front 3 cylinders, and the rear turbo is powered by the rear 3 cylinders. The turbo chargers are of equal size, and are set by the wastegates to limit boost pressure to 10 psi, although the Skyline GT-R has a built in boost restrictor to keep boost under 14 psi.
The first 2.6 L RB26DETT featured twin-turbochargers and produced around 280 HP (206 kW) @ 6800 rpm and 260 ft•lb (353 N•m) @ 4400 rpm. The last series of the RB26DETT produced 280 PS (206 kW) @ 6800 rpm and 289 ft•lb (392 N•m) @ 4400 rpm. However, several stock (unmodified) engines have been dyno tested and reported to obtain closer to the 320 HP mark. The reason for this discrepancy is a gentlemen's agreement between Japanese automakers to limit the advertised horsepower of any vehicle to 280 PS (276HP). It is widely known for its strength and extreme power potential. It is not uncommon for 600 hp to be achieved without modification of the engine internals. With regular maintenance, many of these engines have been driven way past the 100,000 mile mark with a few heading toward 200,000 miles. With extreme modification, the RB26 motor is capable of power in excess of 1 megawatt(or over 1,340 hp).
There is a common oiling problem with the pre-1992 R32 RB26 motors, as the surface where the crank meets the oil pump was machined too small, eventually leading to oil pump failure at high rpm. This was fixed for later versions of the RB26. After market performance parts makers also make oil pump extension drives to rectify this problem.
Originally the R32 GT-R was planned to have a 2.4L RB24DETT, and compete in the 4000 cc class (in Group A rules, the displacement is multiplied by 1.7 if the engine is turbocharged). This was when Nismo was going through the process of designing the R32 GT-R to be a Group A race car. But when the engineers added the AWD system, it would make the car heavy and less competitive.Nismo made the decision to make the engine a 2.6L twin turbo, and compete in the 4500 cc class, resulting in the RB26DETT known today.
The RB26DETT was used in the following cars:

RB26DETT Z2

This is the engine used in the Nissan Skyline GT-R Z-Tune. It uses the stronger RB26 N-1 block, modified with Nismo parts, bored and stroked to 2.8 L (87.0 x 77.7 mm). The end result was the RB28Z2, which produces 510 bhp (368 kW) and 540 N·m of torque.[5]
