Supercomputers
One definition for a supercomputer is “the most powerful computer available at any given time.” These machines are used to solve complex problems such as the design of a supersonic aircraft, modeling of global climates, the structure of oil-bearing formations within the Earth, the molecular design of new drugs, or the prediction of complex financial behavior in securities markets. Two of the first supercomputers were the Control Data Corporation CDC 6600 and CDC 7600. Both were developed by Seymour Cray, one of the founders of CDC. In 1972, Cray left to found Cray Research, Inc., and in 1976 developed the Cray-1, generally acknowledged to be the first true supercomputer.
The Cray-1 used high-speed emitter coupled logic (ECL), the fastest (and most power hungry) logic circuits available at the time. The computer was packaged as a 6.5 ft. high cylinder surrounded by a circular seat. Each circuit board was mounted on a copper heat exchanger through which liquid freon was circulated. The total power consumption of the computer was 128 KW! Processing speed was 130 MFLOPS (millions of floating-point operations per second). In all, 63 Cray-1 computers were sold (at a cost of $5.1 million each).

Modem control software has to test the condition of the CTS and DSR signals before transmitting information to the modem. The modem also has to be conditioned by the computer by applying a logic zero on the modem connections DTR and RTS .
If one of the two communications interface adapters discussed earlier in this chapter is used, most of the modem control is already accomplished by these devices. For example, the Intel 8251A has all four of the pin connections required for modem control, while the Motorola MC6850 contains only some of the connections.

Asphalt versus concrete
Which material is better for your project?
Before a public works (or street maintenance, or road repair) department can decide whether to use concrete or asphalt in a specific application, the department manager must arm himself with information to help him make the best choice.
Asphalt is more common for a department to specify than
concrete. “Asphalt over concrete – that’s the standard. It is
what has been done for so long. But because it is the “standard”
doesn’t necessarily make it the best option for all applications.
Concrete may be better in some instances, the first of which is
new construction. In urban metropolitan areas, where new roads
are being built and existing roadways are being expanded, using
concrete may be a good way to minimize future inconvenience.
Funding is a big challenge. People are looking for short-term
fixes, which have a political impact.
Asphalt also can be specified as a long-term solution. Some pavement types must be completely removed and reconstructed when they reach the end of their design life, but total removal and reconstruction due to structural failure of a thick asphalt pavement is rare. With a thick asphalt structure, it is possible to obtain a ‘Perpetual Pavement’ one that can last indefinitely, with the only rehabilitation being milling of the surface followed by an asphalt overlay. Perpetual Pavement is a relatively new type of asphalt concrete pavement designed to resist structural fatigue distress for at least 50 years. Maintenance is limited to replacement of the surface course

Today is the 10th annual World Toilet Day. Sponsored by the Singapore-based World Toilet Organization, the event is meant to build awareness about the risks that lack of sanitation present to the physical, emotional and psychological health of 2.6 billion people around the world. Fortunately, poor sanitation is receiving an increasing amount of attention from NGOs, academics and other problem-solvers around the world. But there isn’t time to waste, since lack of hygiene contributes to diarrheal diseases that claim the lives of 1.5 million poor children each year.
Earlier this year, The Gates Foundation awarded a total of $3 million to researchers at 8 universities as part of its Reinvent the Toilet competition. Unlike the innovations that are taking place with flush toilets, these grants are aimed at designing, developing and prototyping waterless, hygienic toilets that cost less than $0.05 per user per day. The foundation also awarded a $4.8 million grant to the London School of Hygiene and Tropical Medicine (LSHTM) for a project called Sanitation Ventures. For it, researchers are developing ways to speed up the decomposition process in pit latrines. Organisms such as tiger worms, placed near the surface of the latrines, can effectively increase the speed of composting. Beneath that, in a filtration bed, liquid waste is further treated by aerobic bacteria. The end product is a treated sewage material that can later be used as a fertilizer.
And if that sounds gross, well, get over it. Human-waste-based fertilizer has been used in many parts of the world for centuries. The key is to process it correctly — at the right temperature and for enough time — to ensure that all pathogens are eliminated. In fact, aside from better public health, one of the major benefits of developing sanitation solutions for the developing world is creating an end product with value, such as fertilizer or biochar for energy.

Brazil’s Average Unemployment Rate Falls to Record Low in 2012
By Dow Jones Business News
January 31, 2013
Brazil’s unemployment rate for 2012 fell to 5.5%, down from the previous record low of 6.0% recorded last year, the Brazilian Institute of Geography and Statistics, or IBGE, said Thursday. In December, unemployment fell to 4.6% compared with 4.9% in November, besting the previous record monthly low of 4.7% registered in December 2011, the IBGE said.
The 2012 average unemployment rate was in line with the 5.5% median estimate of economists polled by the local Estado news agency. Analysts had also pegged December’s unemployment rate at 4.4%.
Brazil’s unemployment rate remains at historically low levels despite sluggish economic activity. Salaries have also been on the upswing in an ominous sign for inflation – a key area of concern for the Brazilian Central Bank after a series of interest rate cuts brought local interest rates to record lows last year. Inflation ended 2012 at 5.84%.
The average monthly Brazilian salary retreated slightly to 1,805.00 Brazilian reais ($908.45) in December, down from the record high BRL1,809.60 registered in November, the IBGE said. Wages trended higher in 2012 as employee groups called on Brazilian companies and the government to increase wages and benefits to counter higher local prices. Companies were also forced to pay more to hire and retain workers because of the country’s low unemployment.
The IBGE measures unemployment in six of Brazil’s largest metropolitan areas, including São Paulo, Rio de Janeiro, Salvador, Belo Horizonte, Recife and Porto Alegre. Brazil’s unemployment rate, however, is not fully comparable to jobless rates in developed countries as a large portion of the population is either underemployed or works informally without paying taxes. In addition, workers not actively seeking a job in the month before the survey don’t count as unemployed under the IBGE’s methodology. The survey also doesn’t take into account farm workers.
