It's the indirection thing again: rather than provide a C toolchain for each platform, you load Java (or Python, Ruby, ...) which is already precompiled for the platform which then allows a single toolchain across all platforms. > BTW, if I was King of the World, universities would teach assembler > programming > first. I think that sort of worked in the 1980s when computers were (relatively) simple, but I don't think it works now. Clearly any self-respecting programmer should be able to work with assembly language, so it needs to be taught, but these days it comes as the link between hardware and software rather than being the language of software. > I learned BASIC first, then FORTRAN, then I learned assembler (6800) and it > was > like someone turned the lights on. It's all about the operational semantics. Some people are happy with very abstract semantics and so can work with the likes of Fortran very well without knowing assembly language. For others the link to how the computer actually works is critically important. > I liken it to trying to teach kids algebra first, give them a calculator, and > never bother teaching them arithmetic. > > A programmer who doesn't know assembler is never going to write better than > second rate programs. I am not sure I'd go quite that far but I agree that all programmers really ought to have worked with assembly language at least once in their lives. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@russel.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
