http://www.ddj.com[..]ept_url=/hpc-high-performance-computing/ Interesting, I am not sure if I agree, but chrome ( which use fork ) are really cool in performance:
There’s another problem with Unix programming in Ruby that I’ll just touch on briefly: Java people and Windows people. They’re going to tell you that fork(2) is bad because they don’t have it on their platform, or it sucks on their platform, or whatever, but it’s cool, you know, because they have native threads, and threads are like, way better anyways.
Fuck that.
Don’t ever let anyone tell you that fork(2) is bad. Thirty years from now, there will still be a fork(2) and a pipe(2) and a exec(2) and smart people will still be using them to solve hard problems reliably and predictably, just like they were thirty years ago.
MRI Ruby people need to accept, like Python (you have seen multiprocessing, yes?), that Unix processes are one of two techniques for achieving reliable concurrency and parallelism in server applications. Threads are out. You can use processes, or async/events, or both processes and async/events, but definitely not threads. Threads are out. http://tomayko.com/writings/unicorn-is-unix

6:57:06 PM: Carfield W Yim/: hi... just get distracted by a call... now I created a member.... then I edit it and put the create table scripts there. However, it only allow me to put 18 lines, is that normal?
6:57:52 PM: Srikanth X Krishnaswamy/: type in the letter 'I' followed by 10 in the first column- inserts 10 lines
