msdn.microsoft.com: The Integer, Long, and Byte Data Types
Three data types in Microsoft© Visual Basic© for Applications (VBA) can represent integers, or whole numbers: the Integer, Long, and Byte data types. Of these, the Integer and Long types are the ones you are most likely to use regularly. The Integer and Long data types can both hold positive or negative values. The difference between them is their size: Integer variables can hold values between -32,768 and 32,767, while Long variables can range from -2,147,483,648 to 2,147,483,647. Traditionally, VBA programmers have used integers to hold small numbers, because they required less memory. In recent versions, however, VBA converts all integer values to type Long, even if they are declared as type Integer. Therefore, there is no longer a performance advantage to using Integer variables; in fact, Long variables might be slightly faster because VBA does not have to convert them. The Byte data type can hold positive values from 0 to 255. A Byte variable requires only a single byte of memory,
ZDNet.com: Website creation: Dreamweaver v open source
Summary: Adobe’s Dreamweaver is widely used by web developers, but it won’t suit Linux users or those on tight budgets. Free and open-source (FOSS) alternatives are available, but how do they match up?
NYTimes.com: Into the Bitcoin Mines
Mr. Abiodun’s opinion of Bitcoin changed in January, when he saw the price rising. He installed a free application on his home computer that linked him into the Bitcoin network and set it to mining, harnessing the power of his graphics card, which is the part of a normal computer best suited to doing the code work. Mr. Abiodun’s computer was in the guest room of his house in southeast London. Working at HSBC during the day and tinkering with his Bitcoin system at night, he realized if he wanted to make any money, his computer would have to run around the clock. The constant computing, however, overheated the graphics card and pushed the computer’s exhaust fans into overdrive. When he added another graphics card, then a new computer, the room became too noisy for guests to sleep, and the windows had to be kept open to release the heat. That did not make his wife, Gloria, who was pregnant at the time, very happy.
