12/22   Does anyone know if there's a system call to test if a port is
        availible without actually attempting to bind to it?  Such a call
        would be really useful for me.
        \_ You could try to connect to it.
           \_ You could also parse the output of "netstat -an" to see if
              there's anything listening on the port.  Are you sure this
              is what you want, though?  If you're eventually going to
              bind to the port, trying to check beforehand whether it's
              available will only create a race condition.
              \_ Yes, but this is a very unusual case.

3/29    A friend wants a PC (no mac). She doesn't want Dell. Is there a
        good place that can custom build for you (SSD, large RAM, cheap video
        card--no game)?
        \_ As a side note: back in my Cal days more than two decades ago when
           having a 387SX made me the only person with floating-point hardware,
           most machines were custom built.

11/4    Holy cow, I got a warning from my ISP that they were notified
        by BSA/baytsp.com that I was copying music/video/software.
        Do they do port scan or something? That's a first for me.
        \_ They hang out on P2P networks and track IP addresses.  -tom
           \_ I believe they are paid by content providers to perform this
              monitoring service, so you should only run this risk with content

10/1    I am thinking of installing firefox on soda under my home directory.
        Will this make me a hozer?
        \_ Possibly. I wonder if we should have another VM for that...btw,
           I remember someone saying they're glad we're not on FreeBSD
           anymore, but last I checked, a bunch of our stuff is on FreeBSD,
           but our login server is not.

9/9     What should outbound mail server be when reading mail from soda
        with IMAP? Is there a FAQ?
        \_ It's <DEAD>mail.csua.berkeley.edu<DEAD> (same as for incoming mail).
           \_ "The message could not be sent because connecting to SMTP
               server <DEAD>mail.csua.berkeley.edu<DEAD> failed. The server may
               be unavailable or is refusing SMTP connections."

7/27    I have an actual technical question here. My MySQL DBA tells me
        that I can't expect a MySQL port to be able to run effectively
        on more than a two CPU box, he says that the extra CPUs will
        sit there unused. Is this true? I have a bunch of new quad core
        servers that I would like to use as Database machines. -ausman
   \_ It's not that simple.  If you stress test your new fancy multi core

7/2     Is imaps working?  What are the hostnames of the "incoming and
        outgoing mail servers" for CSUA email, and what kind of options
        should one set?
        I also noticed that we seem
        \_ Setup yer .forward or .procmailrc for now. I'm at a loss, too.
        \_ <DEAD>mail.csua.berkeley.edu<DEAD>. Using SSH (on default port 993) like before.
