Online retailing giant Amazon on Thursday entered India with the launch of its shopping website junglee.com, in a major boost to the country's rapidly-growing e-commerce business.

The website offers 12 million products across 25 categories -- including books, movies, mobile phones, cameras, toys and clothing -- besides its best-selling Kindle e-book reader, the company said.

Facebook's 800 million users have made it a household name but some holdouts -- technophobes and privacy zealots among them -- are still refusing to join the social networking party.

Facebook -- founded in 2004 by Mark Zuckerberg, then a 19-year-old Harvard student -- filed documents with the Security and Exchange Commission Wednesday to go public, seeking to raise $5 billion in its initial stock offering.

Mozambique has signed a 20-year contract with Internet cable operator SEACOM to provide broadband access to government institutions and schools, science ministry official Rufino Gujamo said Thursday.

Figuring out how to pack a processor and other sophisticated equipment into a machine gun bullet has been a challenge, but engineers at Sandia National Laboratories say the miniature guidance system they've developed is a breakthrough.

A bullet that directs itself like a tiny guided missile and can hit a target more than a mile away has the potential to change the battlefield for soldiers without costing too much, engineers said Wednesday.

Sweden's Supreme Court said Wednesday it would not hear an appeal brought by the founders of filesharing site The Pirate Bay, meaning jail terms and hefty fines imposed by an appeals court in 2010 stand.

"The Supreme Court has today decided to reject the request from two of the plaintiffs to seek a preliminary ruling from the European Court of Justice and will not hear an appeal in the so-called Pirate Bay case," it said in a statement.

ARM Holdings, the British company whose microchip designs are used to help power Apple's iPads, posted strong fourth-quarter profits Tuesday thanks to keen demand for smarter technology.

Pre-tax profits jumped 42 percent to £49.7 million ($78.4 million, 59.7 million euros) in the three months to December compared with the same period in 2010, ARM Holdings said in a statement.

A group of Internet hackers said Tuesday it took down the website of Brazil's second largest private sector bank, one day after it did the same with the country's largest private bank.

The group that calls itself "Anonymous Brasil" said on Twitter: "Attention sailors: Target hit! The http://bradesco.com.br is sinking. TANGO DOWN."

Ukrainian authorities say they have shut down a popular file-sharing website, saying it violated copyright laws.

Interior Ministry Spokesman Volodymyr Polishchuk said Wednesday that Ex.ua was closed after complaints from Microsoft, Adobe and other companies.

Google, Facebook and other big tech companies are jointly designing a system for combating email scams known as phishing.

Such scams try to trick people into giving away passwords and other personal information by sending emails that look as if they come from a legitimate bank, retailer or other business. When Bank of America customers see emails that appear to come from the bank, they might click on a link that takes them to a fake site mimicking the real Bank of America's. There, they might enter personal details, which scam artists can capture and use for fraud.

Twitter CEO Dick Costolo sought to calm the global outrage over the company's new country-by-country censorship policy, complaining in part that the issue is being treated with the same kind of shorthand that has made Twitter popular.

Speaking at the All Things D conference on Monday, Costolo repeated the company's justification for the policy change it announced last week: By taking down tweets only in the country where Twitter believes they may have violated local laws, it is making sure the maximum 140-character-long messages are still available to the rest of the world.
