Using PHP's proc_open(), I can start a process, read from STDOUT and STDERR (separately) an arbitrary number of bytes at a time using fread() while the process is running, detect when the process is done using feof() on the STDOUT and STDERR pipes, and then use proc_close() to get the exit code of the process. I've done all of this in PH...

I'm trying to get a simple multicasting example to work on Linux (I've tried both RHEL 4 2.6.9 and Ubuntu 8.04 2.6.24). The general idea is that I would like the server to bind to a unicast address and then add itself to the group ff02::1. I would then like it to receive multicasts sent to ff02::1. The code below works on Mac OS X 10.5 (...
Hey, how come that JVM always uses only one from four cores ? If I run 2 or 3 Java apps, one core is employed on 100% and the rest is sleeping having nothing to do. Apps like Liferay, eclipse, sonatype nexus etc., multithreaded overlords. There is plenty of free RAM also. ps and top shows what I just said, and entire system gets out ...

I have a for loop that I pass through ssh to a server that is formatted to look kind of like this... i=0 for cmd in cmd_list; do ${cmd} | sed "s/^/OUTPUT_${i}_: /" & (( i++ )); done; wait The idea is that the for loop will run a list of commands that I give it and pipe each one to sed where sed prepends each line of output with a comm...

Hi, I have a long-running Python process that is generating more data than I planned for. My results are stored in a list that will be serialized (pickled) and written to disk when the program completes -- if it gets that far. But at this rate, it's more likely that the list will exhaust all 1+ GB free RAM and the process will crash, lo...
