General Strategy With the fast-paced development of computer hardware and software anyone who uses computers profesionally needs a strategy about how to allocate their time and money for hardware and software. . Operating System. In my view there are two alternatives today either do everything in Microsoft Windows and other commercial software or use GNU Linux the free unix operating system together with the free software built on top of it see in addition to Microsoft Windows. I will argue here for the second route. It is true GNU Linux has a steeper learning curve than Windows but this also means that you have a more powerful tool and serious efforts are under 535 536 21. ABOUT COMPUTERS way to make GNU Linux more and more user friendly. Windows on the other hand has the following disadvantages Microsoft Windows and the other commercial software are expensive. The philosophy of Microsoft Windows is to keep the user in the dark about how the computer is working . turn the computer user into a passive consumer. This severely limits the range of things you can do with your computer. The source code of the programs you are using is usually unavailable therefore you never know exactly what you are doing and you cannot modify the program for your own uses. The unavailability of source code also makes the programs more vulnerable to virus attacks and breakins. In Linux the user is the master of the computer and can exploit its full potential. You spend too much time pointing and clicking. In GNU Linux and other unix systems it is possible to set up menus too m but everything that can be done through a menu can also be done on the command line or through a script. Windows and the commercial software based on it are very resource-hungry they require powerful computers. Computers which are no longer fast and big enough to run the latest version of Windows are still very capable to run Linux. . GENERAL STRATEGY 537
