8/18    trying to write an intentionally slow regex.
        what is your worst regex ever?
        this is using MySQL regexp but I'll also accept
        perl format         --brain
        \_ you need to know how regex is implemented internally in order to
           have a worst regex in terms of running time. Something that uses

5/2     How do I get the L1/L2 cache size and cache line size on my machine?
        Can I find this stuff out at compile time somehow?
        \_ You aren't planning on running your code on any other processors?
        \_ May I ask what it is you want to achieve ultimately? If you don't
           know your architecture and want to find out dynamically, there are
           tools that can peek/poke to give you definitive answers, plus you get

11/27   I'm using select to do a nonblocking check to see if a single socket
        has anything to read off it.  Problem is, I can have up to 12228
        file descriptors, and Linux fd_set only supports up to 4096.  Any idea
        what I can do about this?  (Or a better solution?) -jrleek

10/6    locale question
        is en_US equivalent to POSIX and/or en_US.UTF-8?
        What does Redhat default to?  UTF-8?  en_US?  POSIX? - danh
        \_ no, POSIX is essentially C.  en_US.UTF-8 is, UTF-8.

3/27    Anyone have experience with embedded Perl in C/C++ apps? I've been
        using this for a while but now I find out I can't "use POSIX" for
        example in the Perl code, and trying to follow instructions on
        the internet for how to load extensions like this doesn't seem to
        work. So, maybe someone can help describe what should be done...
        I tried putting in an xs_init function generated by ExtUtils, but

2/7     I have a little multi-threaded server I'm writing, and I log at
        the start of each call and at the end of each call.  I log by
        having a global lock file, lock, write, flush, unlock.  This
        seems like a bottleneck, is there a better way to log from a
        multi-threaded server? Perhaps something like syslogd where I
        could send messages to another process that would log for me?

6/14    Does anyone know the POSIX specified way to get the fully
        qualified domain name of the local machine in a C program?
        gethostname just returns the name of the box without the domain.
        \_ There probably isn't a POSIX-specified way, as there is no
           single way to map machine->FQDN.  (What if a machine has
           two, or 1000 FQDNs?)  -tom

3/24    How do I do non-blocking read in Perl? For example, let's say I do
        open(FD, "tail -f file.log |");
        And I'd like to read it, but not block it. Can that be done? -ok thx
        \_ Yes. You need to use fcntl to mark FD as non-blocking and then
           you need to use select and sysread to read from FD.

2/17    I need to write some code using sockets that will work on both
        Windows and LINUX.  Ideally, I'd like to just use the standard
        POSIX sockets and have the code work on both platforms.  Based on
        info from MSDN, it looks like this is possible but I'd like to
        ask people on the MOTD if they've encountered any inconsistencies
        or other issues doing things this way.  Thanks.  -emin

12/13   The manpage for fflush says that fflush(NULL) will flush all open
        buffers-- is this POSIX (or another standard), or just a BSDism?

9/16    I want to compile a simple Windows console app, are there any
        gnu/free compilers for windows that would do it? I'd rather not
        install visual studio and all its crap... my app is in C and calls
        windows APIs.. thanks.
        \_ I'd say Cygwin but it probably doesn't support your Windows calls.
           Just out of curiosity, what sort of console app could you write

8/19    So, can someone explain Posix to me?
        \- POSIX IS THE STANDARD --psb
        \_ I usually hear about it with respect to POSIX threads.  Writing
           threaded programs can be a mess if the API for each architecture
           is different.  So, every architecture supports POSIX threads.
           Write once, run everywhere (with lots of #ifdefs).  Win32 does
