To protect its seagoing interests and trade routes, Portugal established strategic garrisons in Goa (India), Malacca (East Indies), and Hormuz in the Persian Gulf. Portuguese explorers then embarked upon Macau (now Macao), the Congo, and various other parts of Africa, including the Sudan. The Portuguese policy was to avoid armed strife and to develop a trade empire, rather than to conquer nations. To this end it succeeded with relatively few blood-soaked episodes in its colonial history. Adventures abroad, however, proved disastrous during the second half of the 16th century. In 1557 the 14-year-old boy-king Sebastião ascended the throne, the beginning of a calamitous reign that was to end at the battle of Alcacer-Quiber (Morocco) in pursuit of a vain crusade. Sebastião's untimely demise, alongside some 18,000 ill-prepared, badly led followers, set the stage for a crisis of succession. For many years afterwards, legends and rumors bizarrely insisted that the king was still alive, and imposters turned up from time to time claiming the throne; those who were plausible enough to be deemed a threat were summarily executed. In fact, the only rightful claimant to the crown was the elderly Prince Henry. But after two years of alternating between the throne and his sickbed, he died, heirless. Surveying the situation and smelling an opportunity, Spain occupied the power vacuum, and Portugal's neighbor and long-time antagonist became its master. Spanish rule dictated Portugal's inadvertent involvement in Spain's ongoing wars. In 1587 a squadron of British ships commanded by Francis Drake attacked the Algarve (now a "legitimate target" as Spanish territory) and sacked Sagres, thus depriving the world of the relics of Henry the Navigator. Nine years later Faro was torched. The 1386 Treaty of Windsor, by which Britain and Portugal had pledged eternal friendship, seemed a distant memory. Portugal's empire was gradually eroded, and many of its trading posts (with the notable exception of Brazil) were picked off by the British and Dutch. Finally, after 60 years of Spanish rule, Portuguese noblemen (aided by the French, then at war with Spain) organized a palace coup and restored independence. The Great Disaster Portugal's greatest misfortune struck on All Saint's Day, 1 November 1755. <sep>Who became sick and died heirless?<sep>Prince Henry became sick

(Financial Times) -- The increasing amount of personal information that can been gleaned by computer programs that track how people use Facebook has been revealed by an extensive academic study. Such programmes can discern undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by Cambridge university academics. In one of the biggest studies of its kind, scientists from the university's psychometrics team and a Microsoft-funded research centre analysed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles. The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion and political leanings. Personality types and emotional stability were also predicted with accuracy ranging from 62-75 per cent. Facebook declined to comment. The study highlights growing concerns about social networks and how data trails can be mined for sensitive information, even when people attempt to keep information about themselves private. Less than 5 per cent of users predicted to be gay, for example, were connected with explicitly gay groups. Michal Kosinksi, one of the report's authors, told the Financial Times that the university's techniques could easily be replicated by companies to infer personal attributes a person did not wish to share, such as sexual orientation or political views: "We used very simple and generic methods. Marketing companies and internet companies could spend much more time and resources, and hence get much higher accuracy than we did." Last week , the EU agreed to water down proposals for a radical overhaul of data privacy regulation. The move reflects governments' reluctance to impede internet businesses that might spur economic growth, and follows fierce lobbying from technology companies including Facebook and Google. Personal data has become big business. Wonga, the UK online lender, makes credit judgments within seconds based on thousands of pieces of information, including an applicant's Facebook profile. Tesco, the supermarket chain, this month started to use its customers' shopping histories to sell targeted online advertising. The report also revealed some unexpected correlations -- such as people who liked 'curly fries' having higher IQs, while those who like Facebook's "Sliding on Floors With Your Socks On" page were unlikely to use drugs. <sep>Has Facebook commented on the ability of computer programs that track how people use Facebook to discern undisclosed private information?<sep>In a limited manner
