comment Modify ulimit (open files) of a specific process
@test - I've never raised the hard limit. Found this: blog.samat.org/2011/04/05/… and this wiki.brekeke.com/wiki/Increase-File-Descriptor-Limit-on-Linux They say the same thing.

comment Fork vs. thread system time
Maybe, maybe not. Does the system actually context switch to the child processes? That's not guaranteed: stackoverflow.com/questions/6696959/…

@SubiSuresh - I believe you wrote the truth.

comment How does the server find out what client port to send to?
System call getpeername() should let you do that on any open socket. The accept() system call that the server code has to use to get a socket file descriptor to communicate back to the client has a parameter ("sockaddr" in my man pages) that contains the prospective client's IP address and TCP port number.

comment Why is dnsmasq putting my router IP in /etc/resolv.conf instead of 127.0.0.1?
On which machine, 'A' or 'B', does dnsmasq run? Does dnsmasq do DHCP as well as DNS? What is the value of the "resolv-file" parameter in dnsmasq.conf?

comment Why is my download speed a lot lower in Linux than other OS?
Check the arithmetic - I've seen Windows FTP clients that were off by a factor of 10 when they stated download speeds, elapsed time and bytes.

comment Who cuts off first symbol of process substituted file and for what reason?
Same behavior for RHEL 5.0, bash 3.2.25, php 5.4.6. I can add that the problem also happens for named pipes. Do this: mknod named_pipe p; echo 123 > named_pipe; # go to another window; php named_pipe; It will show you "23".

comment Who cuts off first symbol of process substituted file and for what reason?
For what it's worth, I get the same behavior on a Slackware 11 box, bash 3.1.17, PHP 5.3.6. You might want to try "echo" instead of "cat" or "php" in your script to see what the "<(...)" construct gives you.

comment what's wrong with embedding php scripts inside bash ones?
"If a file is pure PHP code, it is preferable to omit the PHP closing tag at the end of the file." You be the judge if your file is pure PHP code.
