Compared with IBM, Microsoft is a mere young company. Founded in 1975, it rose swiftly to dominate the world of personal computing with its Windows operating system and Office suite of word-processing and other productivity tools. But the company is now showing some worrying signs of middle-age fatigue. In particular, it is struggling to find a growth strategy that will enthuse disappointed shareholders. Complaint are understandable. Since Steve Ballmer took over from Bill Gates as chief executive in 2000, Microsoft’s share price has decreased and the company has lost its reputation as a tech trend-setter. It has been left behind in hot areas such as search and social networking by younger companies, some of which love to thumb their noses at their older rival. Eric Schmidt, the executive chairman of Google, recently proclaimed that leadership in the tech world had passed from Microsoft and others to a "Gang of Four" fast-growing, consumer-oriented businesses: Google, Apple, Amazon and Facebook. Few would object to that. The question is: what，if anything, can Microsoft do to change it In at least some respects, the company appears to be suffering from similar ailments to those that laid IBM low before Lou Gerstner was hired in 1993 to get it back on its feet. These include arrogance bred of dominance of a particular area-mainframe computers at IBM, personal computers at Microsoft—and internal fiefs that hamper swift change. As IBM’s experience shows, recovery in the tech world is possible. And some observers see encouraging signs of progress at Microsoft. Sarah Rotman Epps of Forrester, a research firm, reckons that Windows 8, a forthcoming version of Microsoft’s operating system, could be a serious competitor to Google’s Android on tablet computers if the company can get it to market next year．Microsoft is also in far better shape financially than IBM was at its lowest point, so it can afford to splash out on acquisitions such as its recent $8.5 billion purchase of Skype, an internet-phone and video-calling service. That bet and an alliance with Nokia in mobile phones show that Microsoft is trying to bulk up in promising areas. Yet sceptics worry that such initiatives are not the product of an comprehensive strategic vision, but are instead temporary moves designed to calm critics who fear Microsoft is drifting downwards. David Einhorn, a prominent hedge-fund manager whose fund holds shares in Microsoft, has publicly called for a change at the top of the firm, arguing that Mr Ballmer is "stuck in the past". So far, the company’s board, chaired by Mr Gates, has backed its chief executive. But if IBM’s history is a guide, Microsoft may yet end up jettisoning its leader. It can be inferred from the first paragraph that______.
A small group of Internet security specialists gathered in Singapore to start up a global system to make e-mail and e-commerce more secure, end the rapid growth of passwords and raise the bar significantly for Internet fraud, spies and troublemakers. The Singapore event included an elaborate technical ceremony to create and then securely store numerical keys that will be kept in three hardened data centers there, in Zurich and in San Jose, Calif. The keys and data centers are working parts of a technology known as Secure DNS, or DNSSEC. DNS refers to the Domain Name System, which is a directory that connects names to numerical Internet addresses. Preliminary work on the security system had been going on for more than a year, but this was the first time the system went into operation, even though it is not quite complete. The three centers are fortresses made up of five layers of physical, electronic and cryptographic security, making it virtually impossible to damage the system. Four layers are active now. The fifth, a physical barrier, is being built inside the data center. The technology is viewed by many computer security specialists as a ray of hope amid the recent cascade of data thefts, attacks, disruptions and scandals, including break-ins at Citibank, Sony, Lockheed Martin, RSA Security and elsewhere. It allows users to communicate via the Internet with high confidence that the identity of the person or organization they are communicating with is not being tricked or forged. Internet engineers like Dan Kaminsky, an independent network security researcher who is one of the engineers involved in the project, want to counteract three major deficiencies in today’s Internet. There is no mechanism for ensuring trust, the quality of software is uneven, and it is difficult to track down bad actors. One reason for these flaws is that from the 1960s through the 1980s the engineers who designed the network’s underlying technology were concerned about reliable, rather than secure, communications. That is starting to change with the introduction of Secure DNS by governments and other organizations. The event in Singapore capped a process that began more than a year ago and is expected to be complete after 300 so-called top-level domains have been digitally signed. Before the Singapore event, 70 countries had adopted the technology, and 14 more were added as part of the event. While large countries are generally doing the technical work to include their own domains in the system, the association of Internet security specialists is helping smaller countries and organizations with the process. It is suggested in Paragraph 4 that______.
A beautiful woman lowers her eyes shyly beneath a hat. In an earlier era, her gaze might have signaled a mysterious allure. But this is a 2003 advertisement for Zoloft, an inhibitory drug approved by the F.D.A. to treat social anxiety disorder. "Is she just shy Or is it Social Anxiety Disorder" reads the caption, suggesting that the young woman is not luring people at all. She is sick. This does us all grave harm, because shyness and timidness—or more precisely, the careful, sensitive temperament from which both often spring—are not just normal. Indeed, they are valuable. And they may be essential to the survival of our species. But shyness and introversion share an undervalued status in a world that prizes being sociable. Children’s classroom desks are now often arranged in pods, because group participation supposedly leads to better learning. Many adults work for organizations that now assign work in teams, in offices without walls, for supervisors who value "people skills" above all. As a society, we prefer action to contemplation, risk-taking to heed-taking, certainty to doubt. As the psychologist William Hart points out, phrases like "get active," "get moving," "do something" and similar calls to action surface repeatedly in recent books. Yet shy and introverted people have been part of our species for a very long time, often in leadership positions. We find them in recent history, in figures like Charles Darwin and Albert Einstein, and, in contemporary times: think of Google’s Larry Page. Sitters and strollers favor different survival strategies, which could be summed up as the sitter’s "Look before you leap" versus the stroller’s inclination to "Just do it!" Once you know about sitters and strollers, you see them everywhere, especially among young children. Drop in on your local Mommy and Me music class: there are the sitters, intently watching the action from their mothers’ laps, while the strollers march around the room banging their drums and shaking their maracas. Relaxed and exploratory, the strollers have fun, make friends and will take risks, both rewarding and dangerous ones, as they grow. In contrast, sitter children are careful and shrewd, and tend to learn by observing instead of by acting. They notice scary things more than other children do, but they also notice more things in general. The psychologist Gregory Feist found that many of the most creative people in a range of fields are introverts who are comfortable working in solitary conditions in which they can f0CUS attention inward. Another advantage sitters bring to leadership is a willingness to listen to and implement other people’s ideas. Now, it’s time for the young woman in the Zoloft ad to rediscover her lure. The author suggests that the traditional shyness of a woman______.
