11/16   We'll be taking all CSUA machines offline in the near future for a Soda
        Hall server room reorganization (we're being moved to a neighboring
        server cabinet).  Downtime will hopefully be minimal.  --jordan

12/7    How many TCP retransmits are too many? Here is what I get:
            3594143433 segments received
            3760174421 segments send out
            3801829561 segments retransmited
        \_ rephrase. you can never have too much money. or too little.
           what is, is.
           \_ You always get a few, but I have a bunch of squid servers that
              I just noticed have 500/second, which seems really high to me.
              They do about 20MB/sec at peak so this is a retransmit every
              40K? This is kind of hard to believe, because they are working
              fine.
              More details have been requested so here they are:
              Each server has apache and squid installed and serves about 10M
              requests/day out of memory in 5ms or less. They are configured
              as memory only squid servers. They are middle tier caching
              servers, sitting between an application layer and an API.
              They have 1Gb/sec uplinks to shared switches, which each have
              1 Gb uplinks to the core routers. No other servers on the
              switches are showing this behaviour and the switches themselves
              are not overloaded. Further investigation shows that 99% of
              the connections on the servers are sitting in TIME_WAIT, which
              I actually think is the cause of these retrans. I am still trying
              to figure out who is rudely dropping all their connections to
              these servers, but it is hard, since all traffic is through a load
              balancer (NetScaler).

11/24   What is the best 25-32" monitor out there? I am ready to upgrade
        my 9 year old CRT. -ausman
        \_ How much money are you willing to spend, and how good do you
           really need it to be good? Are you willing to pay $900 for the
           industry standard monitor used by graphics artists, or are you
           so cheap that you'll only want to pay up $400 for something that
           is good enough for coding and checking email? $900 or $400?
           I've uploaded an Apple LED Cinema Display 24" vs. Dell Ultrasharp
           2408WFP, pixel-to-pixel comparisons for you monitor pixel peepers
           out there. Does it mean anything? If you're not a pixel peeper, no.
           link:bit.ly/DellVsApplePixel
           \_ I spent $1k on my last one and will probably spend about that
              this time. I might spend more if I really thought it was worth
              it, but not $15k. If I can get really good quality for less,
              I would be happy to spend less, but I doubt that is true.
              I like to buy good things and then use them for a long time. -a
        \_ "Best" is subjective.  And sorry, I have no recommendation in
           the 25-32" range.  For 24.1", Eizo CG243W.
           \_ $2200 eh? Do you have one? Is it worth it?
              \_ I have a really old L565 and somewhat outdated S2410W
                 (paid around $1700).  Zero complaints about L565.  S2410W
                 uses Samsung's PVA panel, and I'm not quite satisfied with
                 it.  CG243W uses the latest NEC IPS panel.  If it had RGB
                 back-light, I'd pay $3000 for one.  As is, I'm just very
                 tempted.
           \_ Self correction.  Apparently, even CG243W uses LG panel. Where
              has all the high-end gone....  Also, the new SX2462W appears to
              use the same IPS panel, at much cheaper price, but without
              hardware calibration and some other really high-end features.
              That might be a reasonably good buy.  I'm just going to wait it
              out until there's a no-compromise (to me anyway) model.
           \_ Additional information.  Looks like CG232W is the one using NEC
              panel.  It's actually smaller (22.5") but has the same resolution.
              \_ CG232W has a $15k price tag. That is too much for me.
        \_ I hate to sound like an Apple fanboi but when I tried out
           the 24" Apple LED Cinema Display, I was completely sold.
           Stay away from Dell Ultrasharp 24" unless price is an issue.
           Check out http://Amazon.com user reviews.
           \_ Curious why?  I have a Dell Ultrasharp 24" and it has been a great
              solid monitor, used for over 2 years now.  -ERic
              \_ It's a perfectly fine monitor for its price. It has MORE
                 features than the Apple Cinema display, by leaps and bounds
                 AND you can buy several Dells for the price of one Cinema
                 Display. Spec-wise, it is brighter, more contrast, yadda
                 yadda yadda. However, not everything is about features.
                 There's a reason why most graphic artists still prefer the
                 Mac-- better rendition of colors, and the color-balance
                 is simply calibrated very well. I wrote a review on
                 Amazon about this, and it used to be on the top review
                 (10/11 people thought it was useful). I just went back and
                 found out my review is now shifted to the bottom, WTF! They
                 also took out a near microscopic comparison of
                 pixels which I uploaded without giving me any warning!
                 FU Amazon. Anyways here it is:
                 link:bit.ly/DellVsApple24
              \_ We have a bunch of 24" Dell Ultrasharps at work and some
                 have failed, but they were replaced under warranty. They
                 look fine when they are working. The Dell 20" and 30"
                 seem more reliable. If money was no object I'd go with Apple.
        \_ 24" is fine, too. -ausman
        \_ I am going to get the Apple 24" thanks for all your advice. -ausman

12/31   SOMEONE PLEASE FIX KEG!  Why does it keep crashing?
        \_ It's hard to tell. The risk of crashing seems to increase with
           disk activity, or so it seems, but debugging the kernel doesn't
           seem to yield much info. Email root for detailed info; I don't

11/12   What is diff between SAN and NAS?
         \_ NAS=Network Attached Storage.  Appliance which provides disk
             to servers/clients via file-based protocols (NFS, CIFS, iSCSI).
            SAN=Storage Area Netwoork.  Provides direct fiber connections from
             multiple servers to a single storage array.  -tom
            \_ Here is another way to explain It: They're very similar in that
               they are both technologies to have storage separate from the
               server. However with NAS, the storage protocols run over the
               server's normal network interfaces.  With SAN they go over
               special 'dedicated' storage-only connections, typically fiber.
               Furthermore, SAN uses a different storage-optimized protocol,
               whereas NAS typically operates over general network protocols
               such as IP. -ERic

8/10    The thread below has digressed into wikipedia ramblings, so I'll ask
        here.  I read the essay "Intelligent Design: The Scientific Alternative
        to Evolution"
        (found here: http://www.intelligentdesignnetwork.org/publications.htm
        this weekend trying to figure out what ID proponents are actually
        saying.  From reading this I found that the authors were making
        strawman arguments against evolution and didn't appear to understand
        physical science or probability.  Have you read this essay?  Do any ID
        proponents ever address the weak anthropic principle?  Is the 10^-150
        probability the number they use in general to show something as
        unreasonably improbable? -emarkp
        \_ Math is hard. Big numbers are scary. Someone must have done it.
        \_ I don't understand what the weak anthropic principle is supposed to
           explain.  I think 'cosmological constant tuning' needs an answer.
           On a somewhat related note, I read an article somewhere that some
           experimental data shows that possibly some constants aren't really
           constant, and change somewhat as time passes.  -- ilyas
           \_ In that essay I mentioned (in the section "The Fine Tuning of the
              Universe") the authors say: "The force of gravity, the mass of
              the electron, the charge of the proton, etc. are specific, real
              values. Were they even slightly different from what they are, not
              only would life not exist, nothing (of any significance) would
              exist."  They argue that this specifically suggests design.  But
              the weak anthropic principle is that if the universe weren't
              tuned to life, then we wouldn't be here to observe it.  This
              directly contradicts their assertion--they should at least
              address it.  The fact that they don't even mention it is
              suspicious at best. -emarkp
              \_ It is a counterfactual assertion that does not render the
                 current state of affairs any less puzzling.  Sure, if constants
                 were different nobody would be there to comment.  But someone
                 IS there to comment, and constants ARE the way they are.

                 \_ The point is there is a selecting event (i.e. our
                    existence) which makes those constants unremarkable.  If
                    we were to observe a universe at random and the constants
                    were amenable to life, that might be something.  But our
                    universe isn't a random one.  It had to have those
                    constants. -emarkp

                       seem to be a random one.
                    \_ Let's imagine a lottery winner pondering what events
                       lead to his winning ticket.  He might say: 'well given
                       that I _did_ win, the particles in the Universe must
                       have danced just right so I had to have won.  So the
                       fact that I won (at odds of millions to one) is wholly
                       unremarkable.'  Really, the real reason it's not
                       remarkable is because millions of people played, so
                       someone had to have won.  In other words, lots of
                       Universes makes our constant unremarkable.  Our
                       existence does not. -- ilyas

                                           lottery.  We don't know whether

                                           someone just decided to give us
                                           the ticket.  Not only do we not
                                           know, we don't even know whether

                                           play, or whether someone gave us
                                           a winning ticket.  That's the point,
                                           we have less information than Bob
                                           about our situation.  But, just as
                                           in Bob's situation, the anthropic

                                           the two situations are exactly the
                                           same, and in Bob's situation, nobody
                                           invokes the anthropic principle.
                                           So we shouldn't invoke it in our
                                           case either, because our state of
                                           belief shouldn't matter as far as

                             an event 'cosmological constants have the values
                             they hold in our Universe.'  Your claim: P(C|L)
                             is high.  My claim: P(C) is low.  That P(C|L) is
                             high does not explain why C is true, though P(C)
                             is low.  P(C|L) is high just because of the way
                             conditional probability works.  To put it another
                             way, you have to explain why L is true, even
                             though P(C,L=true) is low.  Or if you like, you
                             can marginalize out C, and reasonably claim
                             P(L=true) is also low.  Or to put it yet another
                             way, you are offering features of the distribution
                             P as an explanation for why we have P and not
                             some other distribution P*.  Naturally, that
                             kind of argument doesn't make sense. -- ilyas
                             P(L=true) is also low.  That's an entirely
                             symmetric question, and an entirely symmetric
                             argument would be 'life exists because our
                             cosmological constants are the way they are.'
                             At this point, the argument becomes circular, and
                             I can ask a question about the joint event:
                             i.e. why is C=true and L=true, though
                             P(C=true,L=true) is low.  Saying 'it's true
                             because it happened' isn't answering anything.

                             \_ No, I don't "have to explain why L is true".
                                ID says P(C) is low, thus we were designed.
                                But that doesn't follow.  All we know is that
                                P(C|L) is nonzero, and that P(~C|L) = 0.
                                Also, we don't actually know that P(C) is low
                                in the first place.  -emarkp
                                \_ So you are saying that the joint probability
                                   of the constants being what they are, and
                                   life existing is high?  How do you figure

                                      low (I think my statement that it =0 may
                                      too strong) and that P(C|L) is nonzero.
                                      Everything else is being pulled out of

                                         event question.'  If you make the
                                         argument that P(C,L) isn't low then
                                         you have to explain why maximum
                                         entropy isn't an appropriate assumption
                                         to make. -- ilyas
