Open Sources: Voices from the Open Source Revolution

Post yr be aware: First released January 1999

Freely to be had resource code, with contributions from millions of programmers all over the world: this is often the spirit of the software program revolution often called Open resource. Open resource has grabbed the pc industry's awareness. Netscape has opened the resource code to Mozilla; IBM helps Apache; significant database owners haved ported their items to Linux. As businesses observe the ability of the open-source improvement version, Open resource is changing into a conceivable mainstream substitute to advertisement software.

Now in Open resources, leaders of Open resource come jointly for the 1st time to debate the hot imaginative and prescient of the software program they've got created.

CHANGING REPRESENTATION OF WOMEN IN COMPUTER SCIENCE 29 ■ 1984: The proportion of women earning CS bachelor degrees peaked; women were earning 37% of all CS bachelor degrees (12,066 out of a total 32,435). ■ 2006: After the turning point in 1984, the proportion of women earning CS bachelor degrees fell over a period of 22 years to only 20% (14,406 out of 57,405). A recent Taulbee survey of North American computer science departments shows this downward trend has continued into 2007 [19]. On a positive note, the HERI/USC freshmen survey, in which freshmen are asked to state their intended major, suggests that this decline may level out over the next few years, but it is not yet clear at what level [20].
