9/8     Y2K is nothing. You should be worried about 2038. The end of unixtime
        on 32 bit machines.
        \_ I will be 63 then, long retired. It will be somebody elses problem.
           Maybe I will do what I did for Y2K though, go vacation in some
           remote off the grid location, if there are any left.
        \_ I will be amused if the smartphone religion apocalypse comes thru
           as millions of kids will cry because they cannot tweet for a while.
           \_ kids don't tweet.  Middle-age white boys tweet.
              \_ True. I read that use of Twitter in the 12-18 year old
                 set is much, much less than in the 35-45 year old set.
                 The biggest Twitter user I know is a 42 year old white woman.
                 She is addicted to that crap and Facebook, too. You cannot
                 even invite her to dinner as part of a group, because she
                 will be typing into her Droid the whole freaking evening
                 like a 14 year old - except that her 14 year old doesn't
                 do social networking at all except the occasional post to
                 YouTube. I wonder if one day people will wake up and realize
                 how much time they have wasted keeping in touch with people
                 they don't know well and who probably won't go to their
                 funeral while ignoring their real friends sitting at the
                 dinner table with them.
                 \_ Actually this makes total sense. Here's my take on it.
                    That woman did not grow up with that technology, she grew
                    up on nintendo, vcrs, etc.  Consequently she doesn't care
                    about THAT technology (it was always around, borrring)
                    but the facebook/always in contact with people is new.
                    Her kid, probably grew up more around that sort of thing
                    (Web 1.0, 2.0) and so he don't care about it.
                 \_ You're on to something here. I find that f/b is populated
                    mostly by people reliving high school or killing time
                    with F-ville... or both. That's generally folks my age
                    (~40). The younger ones text each other. That's their
                    social network. Why f/b (where everyone sees what you
                    post) when you can snipe and snicker to your friends?

2/11    Is anyone watching Caprica.  Is it worth it? Do you like it?
        I recently started watching SG:U and it's not bad, oddly.
        \_ Not watching either; oddly trepidatious about Caprica, and
           SG:U lost me at SG:A. However: reviews of Caprica sound good,
           and at least one excellent hard SF writer (John Scalzi) is
           writing for SG:U, so... maybe worth checking out?
           consulting for SG:U, so... maybe worth checking out?
           \_ You should know that it was in the contract stipulation
              for working as a writer for SG:U that you could have never
              written for SG:A.  Atlantis was that bad. and they know it.
              SG:U is pretty good, if you like moral ambiguity, will to power
              and examinations of people striving for power.  Plus it has
              \_ So you directly contradict this?

        \_ any charismatic leader leading with fear.  There's a
        tonne to choose from.
        -Wizards = scientists? lawyers?
        \_ professionals.  Magic replaces science/engineering.
           Check out Dresden Files.  Wizards there can't even be in the
           same room as technology, it breaks/shorts out, glitches, dies.

        What scientific event does the first frame "Do not disturb my circles"
        refer to?  Thx.
        \- not really a scientific event. story about Archimedes's last
           words before being mistakenly [contrary to orders] killed by
           a roman soldier after the occupation of syracuse. note: this
           was the battle where the Mythbuster etc parabolic mirror

7/6     In arithmetic, repeated "plus" is "times", while repeated "times" is
        "to the power".  Is there an operation that stands for repeated "to
        the power"?  My kid asked me and I have no idea.  Thx.
        \- yes, see "up arrow notation". there is a little field of math
           dealing with "rapidly increaseing sequences". from UCB CS you
           may be familar with the POWER of the ACKERMAN FUNCTION for example.
           you also may be interested in RAMSEY THEORY but that is beyond the

6/30    Does the average tech worker in SV really make $144k/yr??? (Business Week)
        \_ Average is meaningless.  Median is the statistic that you should
           care about.
        \_ The smaller headline reads "And with the number of tech grads
           falling, demand will only rise".  The author never took Econ 1.
        \_ The comments to the article don't seem to agree with the article.

1/10    Finally reading Freakonomics: Not terribly impressed. Your thoughts?
        \_ It's popular science writing.  What did you expect?  Hav you read
           any of the original papers that Levitt wrote or referenced?
           \_ No, I haven't. Given the way people were talking about it, I
              somehow expect revelations. Instead I got loud, unnecessary
              admonitions about not leaping to conclusions, often followed by
              the writer's leapt-to conclusions.
              \_ Keep in mind, many people, even well educated ones don't
                 grok the simple idea that correlation does not imply
                 causation.  Freakonomics explication of this is remarkably
                 good.  Have you read many other pop-sci books?  Were
                 there any that you did like? -dans
                 \_ Your first statement is key here and most of why I'm
                    still boggling. You're right, but that scares the hell
                    out of me. From here to "weighs the same as a duck"
                    is not a large leap.
                    \_ Causation is harder than it looks.  For example, is the
                       converse of above true (e.g., does lack of correlation
                       imply lack of causation?)  Or how about this: "when
                       DOES correlation imply causation?" -- ilyas
                       \_ Statistics attempts to answer these questions. I
                          took an econometrics class at Cal which
                          attempted to answer similar questions w.r.t.
                          economic data. That's probably more useful than
                          \_ So are you suggesting 'people on the street'
                             should read statistics literature in order to
                             gain an understanding of causality issues?
                             What DO you suggest they read? -- ilyas
                             \_ I suggest they go home and have a beer and
                                not worry themselves about it. Otherwise,
                                go take a stats class.
                                \_ Despite you dismissing the entire genre of
                                   popular science books in a single stroke, I
                                   am glad the scientific establishment
                                   continues to produce them, and the general
                                   public continues to read them.  Maybe you
                                   should have a beer, and stop commenting on
                                   things you don't understand. -- ilyas
                                   \_ I didn't dismiss the entire genre. I
                                      just said that if someone really
                                      wants to learn then they take a
                                      class. Otherwise, it's not clear
                                      what they might be getting. Some
                                      popular science books are great and
                                      some are garbage. If you don't care
                                      then it doesn't matter, I guess.
                       \_ I am going to assume that you are not asking me
                          to recount the scientific method here.
        \_ I enjoyed it.
        \_ Some topics were surprising to me, but over all I now use it as
           tool for explaning causation and correlation to others who are
           not as experienced with science as I.  Freakonomics is great
           a great popular science.  As with all popular science, there is
           cost involved when explaining the complex to the dull minded.

                    \_ Or they could spend gvt. dollars on something more

              there is a lot of competition for dollars. You have to slave

              not have a good job. It is so much easier to, say, go to law

                    \_ None of your operations are truly O(1).
                       A naive solution like doing a bunch of & operations
                       is just as O(1) by your criteria.
                       \_ In modern processors all 3 operations
                          ( &, &&, and -) are constant time.
                          That makes it O(1).  The naive solution on the
                          other hand is O(n) where n is the number of bits
                          in an integer.  If you double the width of the
                          integer the time to check doubles.  That's not
                          O(1) in any way shape or form.
                          \_ That's my point. Those operations are only
                             constant time up to a certain number of bits.
                             After that it's going to cost you, e.g. with
                          \_ By the same reasoning, lg(n)<64 so it's constant
                             time as well.

                                understand bigO notation.

11/5    What is the difference between acidity and alkalinity? Doesn't
        one determine the other?
        \_ I think they are the same.  If the pH value is less than 7, they
           call the measurement acidity.  Otherwise they call the measurement
        \_ Yes.  Ph = -1*log10(concentration of H+ ions) =
                 Ph = log10(concentration of OH- ions) +14
           But the acids and bases contributing to the overall acidity
           can have complicated reactions.  Ph=7 = neutral
        \_ Yes, 10^-14 = [H3O+][OH-]
           So you see, if [H3O+] increases, [OH-] decreases, and vice versa.
           If there's more [H3O+], it's acidic; more [OH-], alkaline.

9/8     OK, I think daylight-saving time is kinda stupid, but i thought of
        *one* benefit in modern times.  During the summer, electricity demand
        spikes during the day as people run their air conditioners.  There is
        also an evening spike as people come home and turn on TVs, lights and
        ovens.  By setting clocks forward in the spring, it makes people get
        home later in the 'solar day' when it is cooler.  This way the 2 demand
        peaks overlap less and it reduces the amount of electricity required
        at peak.  Anyone have some thoughts?
        \_ if you can't think of any other benefit, you're a moron

9/4     Open ended question for you military guys. If the British SA agents
        or the American Delta Force/Special Forces were involved in the
        now Russian debacle, would it have helped the situation, given that
        the special forces had better tactics, technology, and experience
        in hostage situations than say, the Russian army? I mean, we've had
        technology like Counter Strike to train kids as early as say, 5
        for heaven's sake.
        \_ Answer:  you can't know.  If you check the chest tags of some
           of the Russians involved, you'll note "Spetsnaz", which are highly
           trained for counterterrorism.  The only antiterrorist operations
           I can think of that went flawlessly are GSG9 storming an airliner
           in Mogadishu, and the 1984 London Libyan embassy siege, along
           with some major cockups in many countries.  -John

           hostages, size of the buildings, and you can see why the Russians
           sent more than one. Most SF/SWAT units do not operate in such

4/20    I have a 3 year old computer and the power supply fan just
        started making much more noise.  Is this a fire hazard?
        Will something bad happen to my computer or is it just noisy?
        Any advice would be appreciated.  Thanks.
        \_ Pabst fans.  Very high quality, very quiet.  -John
        \_ It means that your fan is getting dirty. If you don't clean out
        your fan and just let it run, it'll continue to make more and more
        noise as time goes by. It is a fire hazard if your fan ever fails,
        then your powersupply will overheat and potentially damage your
        computer's innards. I've had this happen to me once on a cheapie
        server, and I've seen this happen a couple of times when power
        supplies have failed on my customers' computers.
        The chance of that happening depends on the quality of the power
        supply, but is usually rare. The chance that it affects the
        lifetime of your power supply is common, since the dust coats
        everything in your powersupply, and if you don't clean it out
        every year or so it becomes like insulation.
        I generally like to clean out my fans and the vents every once in
        a while. It just is really annoying in general to use a computer with
        an overly loud fan anyway.
        \_ I have an old P-75 I use as a router.  The fan started making
           noise several years ago and I used to stick wads of paper in it
           to make it stop.  Now the fan doesn't run at all; the box still
           runs fine with no fan, but a computer that old probably doesn't
           produce much heat.
           \_ Forgive me, but what sort of twisted freak logic encouraged
              you to stick kindling in an overheating electrical
              appliance?  I'm not trying to flame, it worked and
              everything, but what the fuck were you thinking?
              \_ yah, this puzzles me also.  it's like, putting a bullet
                 in someone's brain cuz they have a bellyache.  not to mention
                 the fire hazard, etc.  Please elucidate, P75-router-guy....
                 \_ hmm, i removed the fan from my hard drive bay unit
                    because it was noisy.  am i dumb too?
                    \_ Yes.  Absolutely.  No question about it.
        \_ Thanks for the info.  Just one more question: how do you clean
           the power supply fan?  I removed the power supply from the
           machine but the fan is encased in the power supply.  Also,
           the power supply has a sticker which says "THIS PART IS NOT
           \_Obviously unplug the power supply before servicing. You need
           to dissassembly the powersupply, which is easily do-able with
           a phillips head screwdriver. Once you have the cover off you
           want to use either a small vacuum or compressed air to clean
           out the power supply. If the fan needs deeper cleaning or
           needs to be replaced, you need to unscrew the fan from the
           outer casing. There is also a 4 pin power plug you need to disconnect
           so that you can remove the whole unit. Once that is done you can
           easily clean the fan. Make sure you are able to clean the bearings
           which is not easy to do. You may also want to inject some
           lubricant such as silicon gel to smooth out the bearings.
           If the fan is so old or gunky that the
           blade wheel is spinning off kilter, get yourself a new fan.
           This usually means that the bearings or washer (some of these
           cheapie fans don't even have bearings) has gone bad. No amount
           of cleaning is going to save that.
           And I can't stress this enough, MAKE SURE YOU CLEAN THE VENTS.
           I don't know how many people go through the trouble of cleaning
           a PS and forget to do that then complain that the thing gunks up
           after only a couple of weeks.
           If this sounds too complicated for you, get yourself a new
           power supply if the original is one of those cheapie ones.
           And yes, you are on borrowed time if you don't properly ventilate
           a power supply, opposite of what the fellow who stuck paper into
           his powersupply might say. Just FYI, power supply problems are
           probably the leading cause of electronic equipment failure. The
           worst part is that a bad supply leads to other failures, especially
           on cheapie PCBs which use inferior parts.
           One more thing, if you are savvy enough (which you probably aren't)
           check the caps in your powersupply. If any of them don't look right
           you can jerr-rig a multimeter to see if they're still good. The
           first things to go in a powersupply are the caps. Since I deal with
           Sun boxes, it's worth it to my customers to get the powersupply
           fixed vs. use-and-throw.
           \_ You're talking to CSUAers here.  They are professional fan

        \_ One thing with opening up the PS case is that there will be
           electricity left in the capacitators, and it can shock you.
           Unplugging the computer from the wall and then turning it on can
           help dissipate it before you crack the case.

5/25    set lARS Ulrich on Napster fire.
        \_ English speak go need you to school good yes?
           \_ which part of his simple sentence confused your
              fancy book-learned little head?
           \_ i think what he means is that guy just sounds dumb.  he starts
             off ok but then starts rambling a bit in fragments, and starting
             one sentence and then jumping to another. DUHeeeeeeerrrrr!:

        Lars trying to speak (typical sentence):

           I  mean, I can just barely ...
           I know how to get onto AOL, and I will say
           that I have used AOL a couple of times to check some hockey scores.

        Lars trying to speak again

          And I believe, and the people that we talk to about this, we believe,
          that the minute some of these companies become active,
          when they basically come to a point that they become fully
          funcitonal, we believe that there will be technology and a
          way to go after them in the way they can invent this technology
          and make it untraceable. We believe that as quickly as
          they can make it untraceable And I believe, and the people that
          we believe that you can find a way to fuck with it, and we
          have already heard about different ways of doing that.
          So I think it's clear that there is nothing that
          people can talk about for the future that becomes bulletproof.

        I can see what he's trying, but man, it's damn ugly grammatically...

        \_ People, give Lars a break.  Drug induced coma in which he likely
           spends most of his time aside, most people don't speak in complete
           grammatical sentences in everyday speech, and this interview is
           an unedited transcript of a phone interview.  -- ilyas
                \_ Tell us of the stars....
                \_ Yeah, he's lucky he can use a phone.  Imagine if he had
                   tried to type this up on his AOL account.  And uhm, no, I
                   don't really understand where he's trying to go when he
                   talks about the future and untraceable technology.  I'm
                   not sufficiently drugged to enter his zone of understanding.

        LARS IS A DRUMMER.  Other than dpetrou, how many rock drummers
        do you know who have any brains?

3/6  New cryptology advance renders DES _insecure_. Read sci.crypt for
        more info. Basically a machine like soda can break a 10 char crypt
        in about 8 hours. This has SERIOUS security ramifications.
        \_This technology is not that new.  The U.S. government has not
          allowed DES for use with classified documents for years.  This would
          imply that the government has cracked DES long ago.  If the
          civilian population has been able to crack it too, I would not
          be surprised.
        \_Yeah, and I've got a bridge I'd like to sell you, ya twink.
        \_Nice try.
          \_ Actually, I'm not the owner of the account of the person who
             wrote this. I broke into his account using the new super-duper
             technology fu thingy.
        \_ DES never was secure.  They've had DES-cracking LSI chips for at
           least a year that simply do an exhaustive search of the key-space
           really fast.
