If you're were lucky enough to live in a street where lots of people had different kinds of railings, you might have discovered you could get different musical notes as you moved from house to house. Where does the sound come from? When you move your hands and arms, you give them ...
During automatic pricing, the system takes into account the sequence specified by the counter. 3) Condition type The condition type is used for different functions. In pricing, for example, the condition type lets you differentiate between different kinds of discount; in output determination,...
This, for example, is an early cluster (a simple kind of supercomputer, made from networked PCs), that was used at NASA in the mid-1990s. Google's original data centers were also, famously, built from off-the-shelf clustered PCs like these. Photo courtesy of NASA Lewis Research Center ...
Alternatively, it is possible that Beret Guy is suggesting that the amount of water coming out of the dam is greater than the amount travelling into it via the penstock. If so, this indicates that water is finding other paths through the dam (a literal "breakthrough"), which is a very ...
the source material. While it's possible to casually assign numeric values to random pieces of data, these numbers are generally not meaningful enough to compute with and draw any useful inferences from. It is generally possible to perform statistical analysis only on actual measurements, not on ...
The Haskell Compiler also provides type inference, which allows the compiler to deduce the concrete data type of an expression from the context. Thus, it is usually not required to provide type declarations. Nevertheless, using explicit type signatures is considered good style as they are an ...
In the 1980s, he was working at CERN, the European particle physics laboratory, which is staffed mostly by people from universities around the world who come and go all the time, and where people were using all kinds of different, incompatible computers. Berners-Lee realized CERN had no "...
(which are linked to the Internet, like desktop computers, using phone or cable) or falling back on (generally) slower cellphone networks when Wi-Fi isn't available. In other words, there are really two different kinds of broadband—fixed and mobile—and we'll consider them one at a time...
White areas of the page reflect a lot of light; black areas reflect little or none. The light reflects off the page into a light-detecting CCD (charged-coupled device). The CCD turns the analog pattern of black and white areas on the page into a numeric (digital) pattern of binary ...
Aplanecan whizz you round the world, which is pretty amazing, but that's all it can do for you. Acomputer, on the other hand, is a wonderful general-purpose machine that can do all kinds of things from forecasting the weather to calculating your tax return. What makes it so different...
