Everything put into the building that is unnecessary, every cubic foot that is used for purely ornamental purposes beyond that needed to express its use and to make it harmonize with others of its class, is a waste — is, to put it in plain English, perverting someone’s money — George Hill, commercial real estate…
I’ve covered PC compatibility in the past, and tried to explain how just having an x86 CPU and running DOS does not necessarily make your machine compatible with an IBM PC. At the time, this …
The first mechanical device used in Russia for computational purposes was the Russian abacus ( schoty ). This device became "the national calculator" and was used in cashier's offices down to the middle of the 90's. It is interesting to note that the textbook "Trade calculations" published in 1986 devotes a whole…
The 8-bit Z-80 processor is famed for use in many early personal computers such the Osborne 1, TRS-80, and Sinclair ZX Spectrum, and it is s...

MS-DOS game programmers had to deal with several limitations. This article goes over some of these obstacles and explores how we used the DOS/4GW extender & protected mode to unleash the power of 32-bit DOS.
On December 17, a 26 year old Tunisian man named Mohamed Bouazizi reached the end of his rope. An unemployed university graduate, Bouazizi had become a seller of fruits and vegetables in the southern Tunisian town of Sidi Bouzid. When authorities confiscated his wares to punish him for selling without a license…
