Re: [SC-L] free lunch almost over

[Jeff Williams]

I think we're focused on different aspects of 'important.' The sheer number 
of web applications does make concurrency in that environment an important 
issue for this list. Concurrency used to be the province of a relatively 
small number of developers who understood that were working in a 
multithreaded environment. Now the number of programmers who need to 
understand concurrency is, well, almost all of them. That's why the issue is 
important for the list (or at least to me).

I think the "some web site going down" comment doesn't reflect the reality 
of how web technology is used. Virtually every sector (including finance, 
banking, healthcare, defense) depends of web apps. Our economy would 
literally stop if certain web applications failed. Anyway, I think we 
probably agree here that concurrency is a tough issue and pretty 
'important'.

Ummm...  How about realtime fly-by-wire control systems ?

I have no idea, but certainly the number of them has no bearing
on how important they are.  The Boeing 777 is a good example --
having a few of those fall out of the sky is considerably more
important (which was the issue raised) than some web site going
down.
The newest Airbus models use fly-by-wire as well, lest it seem
to be a US-only thing.
Of course if the web site people used the strong software engineering
techniques common in safety critical areas, we would not be having
this discussion, and possibly not this mailing list.
