9/4     Hi, I'm looking for information on UCB's network.  Like what vendor
        do we use and what are the speeds of the various links.  Thanks.
        \_ traceroute.
        \_ We have an OC-48 (650 megabit, but I don't think it's all active
           yet) into Calren2 for our Internet2 link.  All our traffic goes
           to a Calren2 peering point, where our commodity net traffic
           gets sent over two OC-12's to Level3 and Qwest, which act as
           redundant connections.  (If both fail, it can fall back to
           our southern links out of UCLA).  Commodity net traffic is
           currently capped at 90 megabits/sec, soon to go up to 100 mb/sec.
           The dorms have a separate 40 megabit/sec cap, which is also due
           to rise.  SETI@Home has their own ISP link, as do a few other
           major research groups.  -tom
           \_OC-48=2.488Gb/s, OC-12=622Mbit/s, OC-3=155Mbit/s
                \_ Yes, but we don't get it all--it's shared with all the
                   northern UC campuses.  -tom
           \_ is this on a web page somewhere?  Also, do you know which
              vendor we're using at the different uplinks?  Cisco 12000 or
              Juniper M160s?
              \_ upgrades for i2 appear to be using T640s
                 \_ the T640s will be in the backbone.  What will be used
                    to connect Cal to the rest of Internet2?
                    to connect Cal to the rest of Internet2?  From a
                    traceroute, it looks like a Juniper, but it's most
                    likely not a T640.
           \_ Who else has their own ISP links?
           \_ tom, which dept oversees LSCR?
                \_ The "LS" stands for "Letters & Science"   -tom
                   \_ Yes, I know. So is your boss some non-techie at L&S?
                      There is no Berkeley Technology SuperBoss? ok, tnx.
                      \_ There has to be some PA5 somewhere in charge of this
                         stuff.
                        \_ I'm in charge of it.  I report to the Chair of
                           Deans, Ralph Hexter.  Jack McCredie has the title
                           of "CIO", but he's not in the reporting line of
                           anyone except IST, so it's not a particularly
                           meaningful title.  -tom
                           \_ Does Jack know he's not meaningful?  Have you
                              let him know this?
                                \_ I didn't say Jack was not meaningful, I
                                   said the title of CIO is not meaningful,
                                   and I have said that in various public
                                   forums.  -tom
                                   \_ tom, can I sniff your jockstrap?
                                   \_ Wow, so you're like, important?  Gosh.
                           \_ Ralph is still under L&S. What about other
                              colleges? Do they do all their network planning
                              separately or do they let L&S handle it? BTW,
                              thanks for all the info, it's nice to know this
                              sort of hierarchical stuff (why? i don't know)

        Google Wave No More. The people who worked on it were pretty smart.
        They wrote up a super awesome OKR with extremely low bar as a measure
        of success, exceeded everyone's expectations by going above those
        bars, and got big fat bonuses and promotions as a result of their
        planning. Brilliant.

9/20    I am running NAT on an Extreme Networks switch connected to a
        Cisco switch at GigE speeds. Copying a file across the same link
        w/o using NAT gets about 25 MB/sec, but with NAT turned on I get
        2.5 MB/sec. The CPU is 98% idle and there is plenty of RAM. I know
        that NAT in s/w has an overhead but could it realistically be a
        factor of 10 slower?

3/13    I have an actual technical question for the motd. Where can I find
        the generic Cisco-style symbols for Visio 2003? For some reason,
        M$ pulled them from the recent edition and replaced them with
        their own crappy non-standard ones. I don't mean the icons at:
        http://www.cisco.com/en/US/products/prod_visio_icon_list.html
        I mean the generic circle with four arrows for a router, etc. -ausman

12/20   Why the hell does Cisco "The Human Network" advertise on the
        History Channel, and why the hell are they so annoying?
        "... not just network, HUMAN NETWORK!" Dumb shit.

11/13   If I have a application on machine foo sending data really fast to
        an application on machine bar via TCP, and the bar applications job
        is write that to disk as fast as possible, what happens if the
        network stream is faster than the disk writes?
        \_ Look up the differences between TCP/IP flow control and
           congestion control. The answer is in front of you.

10/1    Where's the short Google at 100 guy?
        \_ Me thinks it's a great time to short now.
           \_ Yeah, definitely short it now!  Funny thing about stock
              valuation:  it can sometimes be rational and sometimes
              be irrational.  If everyone hates a stock, and everyone
              shorts it except for a few, and no one who actually owns

10/3    Alright you idiots. I challenge you to list other Google products
        that actually make money besides search and ads. Gmail? No. Maps?
        No. Earth? No. WHAT ELSE?
        \_ Something near 99% of google's revenue comes from search+ads.  There
           is nothing else.  They've been throwing money at random stuff since
           they IPO'd but still have nothing.  Maybe they can buy Skype....
