12/28   Happy holidays everyone.
        For some reason my work's ip address gets logged in /etc/hosts.deny and\
I cannot ssh in anymore from work
        (except from home where I can ssh in fine): anyone knows if this file is\
 auto-generated due to some event? Thanks

12/14   In AES, if someone knows both the plaintext and the ciphertext of my
        data, is there a way other than brute force to figure out my key?  Thx.
        \_ No, AES is intended to be secure against this.  It should even be
           secure if the attacker gets to choose the plaintext and see what it
           encrypts to, or vice versa.

8/29    There was once a CSUA web page which runs an SSH client for logging
        on to soda.  Does that page still exist?  Can someone remind me of the
        URL please?  Thx.
        \_ what do you mean? instruction on how to ssh into soda?
           \_ No I think he means the ssh applet, which, iirc, was an applet
              that implemented an ssh v1 client.  I think this page went away
              along with a bunch of other stuff that was hosted on the old
              FreeBSD based soda.
              \_ it was the mindterm java ssh client. Its still availble
                 if someone wants to set it back up, and the new
                 version even supports ssh2. Very useful to allow you to
                 ssh into the web server from places where you cannot
                 directly install ssh client (i.e. a public kiosk) -ERic
                 \_ Yes, that's the one I meant.  -- OP
                 \_ Typing your UNIX password into a public kiosk isn't
                    secure and there's a number of places that already
                    offer this in an open access mode [use google]:

                    key or two factor auth system at a public
                    keyboard. You have to consider that a keylogger
                    could be installed. I guess if you don't care
                    about compromise it doesn't matter.

        \_ 88% of pittance is still pittance, I don't know how people
          think there is money in click through ads.  Who clicks on them?
          \_ do some math please and come back
          \_ so my question is, are you one of these "know everything about
             everything without researching it"  guys?  Because FYI, Google
             / AOL partnership made $678M in ad revenue last year.  GOOG
             reported $5.54B 2008 Q4 alone.  Most of that is click ads!
             Are you saying 88% x 678M = 596M is a "pittance" ?  And that is
             using the AOL numbers, not Yahoo/Microsoft numbers.
          \_ It doesn't matter who clicks on them it's like the stock
             market, people think other people click on them so they
             value the ad space.
             \_ So one good paper, story, journal can end all this?
          \_ Who watches television or radio ads? One of the things advertisers
             \_ My Parents.  Your Parents.  Your Grand Parents, your neighbors
                who didn't go to Cal.  Your waiter, the guy delivering your mail
                the guy you buy your groceries from, the guy your parents and
                grandparents buy your groceries from.  As for radio, do any
                of your parents drive?  I know it is gauche to admit to drive in
                Blue Belt Bay Area but in the next county over like vacaville
                there are alot of car radios.
                \_ You totally missed the point. The fact is that advertisers
                   only have a very limited way of telling who is listening
                   to their ads and what the effect is on buying behavior.
                   They can get much better real statistics online, which
                   they love.
                   \_ Is click fraud a problem?  Can infact advertising spots
                      inflate their 'standings' by bots?
                      \_ Are these all rhetorical questions?
                         \_ no; how is the problem being addressed?  It looks
                            to me that the same people paying out and taking in
                            revenue can work the system for fraud.  And since
                            they hold all the logs who would know?
                            \_ All the big advertisers use third party
                               verification services, they don't rely on what
                               the website says is their ads delivered. There
                               is an ongoing war about click fraud, this
                               doesn't mean online advertising is dead, there
                               is bank fraud and perhaps more to the point,
                               things like Nielsen rating gaming as well.
  "According to critics, this complex relationship may create a conflict of
   interest. For instance, Google loses money to undetected click fraud when
   it pays out to the publisher, but it makes more money when it collects fees
   from the advertiser. Because of the spread between what Google collects and
   what Google pays out, click fraud directly and invisibly profits Google."
   \_ Right, so that's why all the newspapers are dying and Google is the
      fastest growing big company in the world and advertisings are starting
      to throw big bucks to online media. Because it all doesn't work. And
      all they really need to do is listen to you to wisen up.

        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
        explanation? thx
        \_ Sounds like not a networking problem, but a messed up OS problem.
           Which OS were you seeing this with?  Did you try to diagnose with
           any non-browser tools (ping/telnet/wget/etc ?).
           \_ yes ... dig seemed to resolve ok. ping seems to work. telnet/
              curl behave the same as my browser (wait for a while then
              timeout). I don't totally know how to read traceroute but
              but after about 8 hops it starts showing stars and then
              craps out. The problem came back today. I ssh tunneled to
              csua, and then a couple minutes later, it started working
              fine in my non-proxied/tunneling browsers as well.
              \_ Is this from work or home? 8 hops, wow that is a long way,
                 is it crapping out at a corporate firewall perhaps? It
                 doesn't sound like it though, at 8 hops...
                 \_ I couldn't tell where it was crapping out. It seemed
                    to me like it was bouncing around a bunch of different

3/3/9   Happy Square Root Day
        \_ This morning some guy on KCBS AM 740 was playing with this and said
           something like "if you take the square root of every number, they
           don't look so big anymore.  For example, next week the square root
           of my age is just 8.  And the square root of the $838 billion
           stimulus package is just $29 billion."
           No wonder American kids rank last in math among industrialized
           \_ i think the sqrt of his iq is also 8.
           \_ Dude needs to go back to school, and age 8 seems like a good
              time to learn about square roots.
              \_ Huh? I don't see anything wrong with his statement.
                 \_ sqrt(838e9) is about 915423.
                    \_ I guess. sqrt(838) =~ 29. (Billion dollars) is the
                       units. Depends on how you look at it.
                       \_ Right, but you need to square root the units too,
                          just like sqrt(10000 m^2) = 100 m.  The answer is
                          the same whether you consider the units to be m^2
                          or (10000 m^2) or whatever.
                          \_ I understand this, but what is the square
                             root of "2 dollars"? This is like asking what
                             is the square root of "2 cows". The original
                             statement said "square root of every number"
                             and not "square root of every quantity". You
                             could argue (correctly) that 838,000,000,000
                             is a number in itself and its root is not
                             29,000,000,000, but what about "838 cows"? What
                             is the square root of a cow? I think the key
                             number is 838 and not 838*(units). You have
                             to be pretty pedantical to not realize that.
                             \_ If your units are billions of dollars than
                                your square root units of ~ 31622 * $^(1/2).

                                  29 * 31622 ~=

                                   \_ $^(1/2)  Which is 1/31622 of

                                            units are "$838e9" and I've
                                            decided units are meaningless.
                                            \_ You have to use some common
                                               sense here. The square root
                                               of his age (64) is 8, not
                                               8 (years)^1/2.
                                               \_ But by your logic we can
                                                  make the units billions of
                                                  years, and now the the
                                                  square root of 64 is
                                Better example: the square root of $1 is 1 if
                                you are ignoring units, but the square root
                                of 100 pennies is 10!  100 pennies = 1 dollar
                                so how can those two be different.
                                $1 = 100c
                                sqrt($1) = sqrt(100c)
                                1 * $^(1/2) = 10 * c^(1/2)
                                The difference is in the units.  1 c^(1/2)
                                is, by definition, 1/10th of 1 $^(1/2).
                                \_ But what is a sqrt($)? or a sqrt(cent)?
                             \_ I guess you're right.  Square rooting a number
                                independently of its unit like this makes no
                                sense, but it is what the original statement
                                said, and really it doesn't sound like he was
                                trying to make sense anyway.  (FWIW, I think
                                sqrt("2 cows") is meaningless too, unless you
                                can come up with a meaning for 1.4 cow^(1/2).)
                       \_ Depends on how good you are at math, actually.

2/16    Lea, what does Google security know by now? Should I talk to you
        under a different channel? I can either spill my beans on Valleywag
        or ask you to just vent for me. Either way, I really need to vent.
        If you don't want to help me vent, it's cool. I'll just cross
        reference Soda names with Moma.         -unhappy borg mon
        \_ No one's tracking anyone, no need to get paranoid. I just
           meant that there are ways of telling whether someone's a
           Googler. Anyway, if you are, then email me at chialea@gmail
           or give me a call on my cell. Of course I'll try to help.
           - Lea
        \_ make sure kchang isn't on the security team
           \_ why not? did have a big leak? or is it bc he's crazy?
           \_ agreed that kchang is crazy but nickkral is the one on the
              security team.
        \_ despite what you hear on the wags there are still a lot of
           Google loyalists out there. The Google has eyes and ears,
           and I'd keep it low unless you want to get fired.
        \_ Um, what? can someone fill me in? -t
