The Birth of the First Computer
In the mid-50th century, though the Chinese computing technology was only one or two years later than Japan, after all, but it has been a decade later from the emergence of world's first computer. The unanimous opinion is to learn and master the Soviet Union's technology first, on this basis, according to China's specific conditions, to carry out their own research, that is, "innovation ofter imitation, imitation for innovation. "
In September 1956, China sent a delegation of computing technology to the Soviet Union. Min Naida is the head, deputy head Wang Zheng, fifteen members including Wu Jikang, Fan Xinbi, Xia Peisu, and so on. The former Soviet Union reception unit is the Soviet Academy of Sciences, Preasion Machinery and Computing Technology Institute . In two months, computing technology research, production and education of Moscow, Leningrad were studied respectively, with an emphasis on the M-20 computer.
In April 1957, by the government, China ordered a M-3 computer and B3CM computer drawings information. On the basis of study and drawings information, the development work started. Led by Zhang Zichang and Mo Gensheng, M-3 ( code 103) Computer Engineering Group was organized. Through the efforts of all staff, in close collaboration with Beijing cable plant, China's first digital computer successfully developed on August l,1958. This tube computer with computing speed of 30 times per second filled in our modern electronic computer blank.
When I say “telecommuting,” do you picture yourself easing into the workday in a pair of fuzzy slippers? Well, so does your boss. But the reality is, you're both dreaming. Because a new study shows that folks who work at home at least some of the time put in more hours than those who stay at the office. That's according to work published in the journal Monthly Labor Review.
Telecommuting for a portion of the workweek certain has its appeal. Avoiding the time and cost involved in commuting and presumably having a more flexible schedule and a better work-life balance are all potential pluses. But are employees really able to take advantage of such work-at-home perks?
Researchers took advantage of labor information from census bureau surveys and were surprised by what they found. First off, the proportion of people who work remotely remained unchanged from the mid-'90s to the mid-2000s the most recent data available. Second, those who do telecommute are more likely to work overtime, an additional 5 to 7 hours on top of the standard 40.
Which means that people who work from the comfort of home are not slackers in slippers. They're more likely tech-savvy self-starters—who don't know when to stop.
In the self-driving seat
Google is miles ahead of its rivals in the race for autonomous motoring
Not quite as glamorous as “Knight Rider”
TO GOOGLE is now in broad usage as a verb for retrieving information from the internet. If the tech giant has its way, “I Googled” will become a standard reply to the question, “How did you get here?” On May 28th Google said it would build 100 prototype driverless cars devoid of pedals, steering wheel or controls save an on/off switch. It is the next stage in its apparent quest to be as ubiquitous on the road as on computer screens.
People have dreamed about driverless motoring since at least the 1930s, but only in recent years have carmakers such as Mercedes-Benz and Volvo given the matter more thought, kitting out test cars with the sensors and sophisticated software required to negotiate busy roads. Google has roared ahead by designing a driverless car from the ground up.
But bringing autonomous motoring to the world is proving harder than Google had envisaged. It once promised it by 2017. Now it does not see production models coming out before 2020. The technology is far advanced, but needs shrinking in size and cost—Google's current test cars, retrofittedToyotaand Lexus models, are said to be packed with $80,000-worth of equipment.
Google's latest efforts may have as much to do with convincing the public and lawmakers as refining the technology. The firm stresses the safety advantages of computers being more likely than humans to avoid accidents. The cars will have a top speed of just 25mph and a front end made of soft foam to cushion unwary pedestrians. The benefits could indeed be huge. Driving time could be given over to working, snoozing or browsing the web. Rather than suffer all the costs of owning a car, some people may prefer to summon a rented one on their smartphones whenever they need it. However, the issue of liability in the event of a driverless car crashing has yet to be resolved.
Turning cars into commodities may not be good news for traditional carmakers. But reinventing motoring as a service fits neatly with Google's plans to become as big in hardware as in software. And unlike car firms, which talk vaguely of becoming “mobility providers”, Google has pots of cash to make that a reality and no worries about disrupting its current business. Google admits it still has “lots of work to do”. But one day Googling to the shops may be a common activity.
