article about Java for realtime

[nabbasi]

Those who use Ada for realtime software, might be interested
in this article. It is an interview with Greg Bollella, senior 
programmer at IBM for comming up with Real-time Specification 
for Java (RTSJ) 

http://www-4.ibm.com/software/developer/features/feat-bollella2.html

some quotes:

"Bollella:  In traditional Java, the scheduling and 
synchronization semantics are not precise enough for real-time 
programming. Real-time programmers need to know when tasks will
begin execution and when those tasks will complete execution. 
The RTSJ tightens the semantics of scheduling, synchronization, 
and related constructs."

It goes on to talk about the challenges to use Java for realtime
and the changes needed to made Java more suitable for realtime.

Why are they going through all this trouble to make Java work
better for realtime when there is allready better languages for
that?

Well, good question. On last INFORMS conference (that is not too much
about computing, mostly about Operations Research) there was a
presentation by Brian Kernighan. He was taking about applicability of
various programming languaged for OR. Talking about Java he said that
"this is the first strongly-hyped language".

This is why people are going to use Java - they just need a
strongly-hyped language. Such languages work well for for management
on various levels and the company visibility on Wall Street. Strongly
typed languages work only for developers. Who cares about
developers?... Who needs to care? Developers is a disposable trash.
