LINUX




Summary
   
LINUX is a free UNIX-like operating system that runs on Intel/Cyrix/AMD Pentium, Intel 80x86, Motorola/IBM PowerPC, Motorola 680x0, Sun SPARC, SGI MIPS, DEC Alpha, HP PA-RISC, DEC VAX, ARM, API 1000+, and CL-PS7110.
    
Linux is named for Linus Torvalds, a Finnish engineering student who created the original kernel. Linus didn’t want to use Windows and searched for an inexpensive alternative that would run on low cost IBM PC clones. The GNU open source project was progressing very slowly because of political infighting and an attempt to make the same operating system run the same on numerous processors. Linus received permission to use MINIX as the foundation for his own efforts. MINIX was a small version of UNIX created by Andrew S. Tanenbaum to provide college students with a working version of UNIX with no AT&T owned source code. Linus opened a web site on his university student account and started posting free copies of his source code. During the early days of the project, Linus was posting updated versions several times a day, which directly contradicted the commercial approach of only releasing new versions on an infrequent basis after extensive testing. With the help of a growing number of volunteers (literally tens of thousands), Linus quickly replaced all of MINIX with new all new source code. As Linux caught on in popularity (because it allowed college students and hobbyists to experiment with very cheap Intel hardware), other groups of volunteers ported Linux to a wide variety of additional processors. The success of Linux proved the viability of open source software projects and Linus’s approach of rapid and continual incremental updates proved to be an effective method for harnessing volunteer effort and an excellent method for widespread testing on a wide variety of hardware.

“Linux has achieved a measure of success. In only a few years, the program has evolved from a hacker’s toy into software that is, at least in part, technically superior to Windows NT.” —Stephen Morley, “Revenge of the hackers”, The Economist, July 11th - 17th, 1998 [NOTE: Linux has advanced substantially since this article was published, now surpassing Windows 2000 in every way except user interface and installation, both of which are being addressed by the KDE and Gnome projects.]
