3/7     I have a C question.  I have the following source code in two identical
        files t.c and t.cpp:

1/20    I've been using tcsh as shell program tool (i know, bad shell to

        integer/string to... almost an array-like data structure when
        the output of the xml key/value is more than one (it's more

12/4    A question to you old crufy alumni: So lately we've suggested
        VMs, and been asked why it's necessary. We've suggested top-of-the-line

        ask -- what exactly do you think the CSUA is supposed to _be_?

11/29   I'm experimenting with virtualization, and as a poor college student
        I'm wondering what the best alternatives for virtualization are, and
        how best to cut my teeth on messing with non-linux platforms (or I
        guess interesting stuff on Linux would work too). Right now I've got
        FreeBSD7 running on KVM on my home computer (on a Core 2 Quad), and am

11/23   C++ question: If I have "char *p = new char[10];", is there any real
        difference between "delete p;" and "delete[] p;" after compilation?
        The Standard C free() function only has one form and works for freeing
        both a single character and a character array.  Why are there separate
        forms in C++?  Thx.

6/8     CSUA code guru please help. I need to see my random number

        might be invoked faster than once a second, and seeding using
        time() produced the same result. I tried clock() but it seems
        to return 0. My program needs to be run in Linux/DOS (Watcom

11/12   What is diff between SAN and NAS?
         \_ NAS=Network Attached Storage.  Appliance which provides disk
             to servers/clients via file-based protocols (NFS, CIFS, iSCSI).
            SAN=Storage Area Netwoork.  Provides direct fiber connections from
             multiple servers to a single storage array.  -tom

8/3     VMWare + Windows XP + Validation question. I need to test stuff with
        Service Pack 3 installed. I have a valid key that I own (yeah yeah I
        actually *bought* a copy, please don't flame me for supporting evil

        for testing purposes?  Will Windows or Microsoft detect copies and

7/28    Does it make sense to defragment disks on VMWare? My 80GB disk
        on VMWare isn't really using 80GB, it just uses what it needs.

        \_ If you want to speed up disk operation in your VM, it's best to
           defragment the disks in your VM, then defragment the disk on your
           host machine where the VM files are.
