4/28    what's faster, crossover cable between two computers, wireless,
        or a usb cable?
        \_ crossover cable, of course.
           \_ actually usb2.0 might be faster
                \_ Not if the two machnes have GigE.
           \_  10baseT:  10Mbits/s
              100baseT: 100Mbits/s
                usb2.0: 480Mbits/s
             1000baseT:   1GBits/s
        \_ Keep in mind this traffic has to go over the internal bus.
           \_ and remember, there are 12 eggs in a dozen.
              \_ not a bakers dozen
                 \_ Don't be stupid.
                    \_ There was more value in the bakers dozen than your line
                       \_ Don't be stupid.
                       \_ And there was as much value in the original dozen
                          line as there was in the internal bus line.  What's
                          your point?
                          \_ The other two make sense.  You don't.
        \_ 100mbps and usb2.0 should be fast enough for whatever you are
           doing. 802.11g/a is also probably fast enough.
           \_ i am moving 900 gigs from one place to another.  so
              those little USB ports in my computer, are they
              usb 2.0 ?
                \_ if you are moving 900GB you should know this stuff already.
                   If you are this clueless to start you need to be ready
                   for the world of hurt that you are about to run into.
           \_ Moving or copying?  Sneakernet arrays sounds good here.
                \_ they have the same form factor.  USB2.0 cards cost ~10
                   bucks at frys.
              \_ once or many times?  for once it doesn't matter.
                 \_ more than once.  it matters.
                    \- uh shouldnt you be using deltas then? --psb
                    \_ Get a cross over cable, it will work the
                       best for what you want to do.
                       \- just out of curiosity, are you using/planning
                          to use tcp "only" to move 900gb? if you are
                          going to be using any application level checksumming,
                          can you send me a note about how many tcp checksum
                          failures you see over whatever transport you end
                          up using. ok tnx. --psb
        \- 900 gb? go gige.
           \_ writable dvd.
              \_ at 4gigs per disc?  even at 9, that's over 100.
              \_ IR? . . . floppy? . . . punch cards? . . . licking wires?
        \_ dd if=/dev/clue of=/dev/null

4/26    I see that soda has an ipv6 address but ipv6 traffic from this box
        doesn't actually work (ping6 <DEAD>ipv6.google.com<DEAD>, ping6 http://www.v6.facebook.com
        Is this expected to work?
        \_ Soda doesn't have a real IPv6 address.  The IPv6 addresses you see
           in ifconfig are just link-local addresses; any IPv6-capable machine
           will autogenerate these, whether or not it's connected to an IPv6

5/22    Are LED monitors much better than LCD monitors?
        \_ OLED is still too new to know.  They're direct emitters, so don't
           have a backlight, and can turn completely off, hence better black.
           The early news was that blue pixels burn out relatively quickly.
           \_ FWIW, Zune HD will use OLED.
        \_ Dunno, but I saw a very nice LED TV for just $2K. Wouldn't that

5/2     I have a 1Gbps switch. It is connected to a SANS RAID-1 with
        two WD Green 1T that takes 1Gbps connection, as well as a laptop
        that is also 1Gbps. Online benchmarks show *sustained* transfer
        rate of about 1/2 of 1Gbps with the WD Green... cool!!! But
        in practice, I'm only getting 68Mbps (read SANS->PC file transfer),
        far below what I expected. The switch says both devices are using

4/22    ok, here's a little networking puzzler. I haven't been able to access
        youtube for a couple weeks. Couldn't figure out why. Happened on all
        browsers. traceroute did weird stuff and then timed out. Finally I
        got so frustrated I setup firefox to ssh tunnel through soda.csua,
        which worked great. Then, I kill the ssh proc, quit FF, and now,
        I can access youtube just fine from any browser. wtf? any
