5/9     Register files and SRAMs are built using 6 transistors right?
        If so, how come register files have a delay in the order of ~.1ns
        whereas SRAM have a delay in the order of 10ns? Is it mostly due to
        multiplexors, where the time to select large memories increase?
        \_ Do you mean discrete SRAMs and regfiles?  I suspect their speed is
           I/O-limited.  (Yes, there have been proposals to do SRAMs with
           SerDes interfaces, but I don't know that those proposals have
           gotten anywhere.)  On-chip regfiles and SRAMs do run at chip
           clock freq., and I guess there the speed is limited by loading
           of signals and buses.

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
        M$). Is it possible to register the key once, and then duplicate it
        for testing purposes?  Will Windows or Microsoft detect copies and
        disable the rest the copies?

5/5     Any idea why the AMD only added 8 more registers with the AMD64 arch.?
        Why 16 registers and not, say, 32?
        \_ To double the accessible register count, you need one more bit
           in the instruction stream _per_ register field.  x86 instruction
           set is already packed like rat's nest as is.

2/27    I need to buy a wireless router, can u guys help me out?   I need the
        following features:  wireless, G or better, PPTP dial up, PPoE dialup,
        VoIP/SIP register, DDNS, uPnP.
        I am having a such hard time to find a review site which allow me to
        select these features.   Any ideas?  There are a couple model from
        this small company Draytek has these features, I am having the hardest

2/13    Question about memory relocation:
        These days most h/w has a relocation register. Could the relocation
        address be stored on disk or in kernel memory vs. in a register? Yes,
        that would be slow but is it possible? Do you *need* a relocation
        register or does it exist purely for performance reasons? I was
        reading some paper written by IBM in the 1960s that seemed to

10/29   I became a citizen half a year ago, and I filled out a voter
        registration form at the oath ceremony.  Now do I have to register
        again with the state, county (Alameda) and city (Fremont) before I can
        vote on their ballots?  Thanks.
        \_ register at your nearest park bench
        \_ Just fill out a voter registration form and drop it in the mail.
