8/12    Ruby coders, do you mostly DIY your stuff or use the ruby libs out
        there?   How is their quality compared to other libs you have used
        for other langs?  Thx.
        \_ I use Ruby for hobby stuff, etc.  I use libraries for system stuff
           (web access, process, etc.) but that's about it.  Perl libraries are

10/27   I just read an article that Facebook had moved their database

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

3/12    I am curious what others think of tablets like iPad. They don't seem
        useful to me, but I use my computer for more than web browsing,

        They seem like a disabled laptop to me, but at a higher price.
