8/8     First temp report on the E6600: Given 25C ambient, my case temp is 34C
        and my proc temp at idle is also 34C, using a Zalman fan set to low.
        I will do a stress test tomorrow after I install more stuff. -dgies
        \_ Is it by any chance a Zalman 9500LED?
           \_ As a matter of fact it is.
                \_ That's good to hear because I'm planning on getting an
                   E6600 + this fan along with 2 very quiet 120mm case fans.
        \_ Addendum: It gets up to 40C playing 3D games.  Its possible that
           something more vectorized could heat it up more.

8/8     I want to replace the 30GB HD in a 1Ghz iBook. Will any notebook HD
        do? Any recommendations? Price/Reliability more important than perf.
        I'm looking at a Hitachi Travelstar or Seagate Momentus from newegg.
        \_ I've used Travelstar's before in a PB, they are fine.
        \_ I went through 2 Travelstars before installing a Seagate.

8/9     Annoyed at ValPak's junk mail in your mail box? Now you can request
        to be taken off online! This is similar to a previous post on
        Advo's mailing list, but it is another company. Save the earth,
        save the tree, and screw all junk mail companies now! It takes about
        2-3 months but hopefully it'll work: "Valpak is mailed to 45 million
        households in North America each month. Due to the extensive lead
        times needed to produce and mail Valpak, you may receive additional
        mailings over the next two or three months until your address is
        removed from our mailing lists."
        \_ I don't care about ValPak. How do I stop my local grocery stores
           and those Pennysaver things? The fucking Post Office should be
           forced to obey a "no bulk mail" list.
        \_ You have to give your email address in order to unsubscribe from
           their snail junk mail?  I don't have a good feeling about it -tien
           \_ I gave them my junk hotmail email address that I never use.
              \_ Why would they require it at the first place?  Maybe I am
                 pananoid but I am just not convinced that this page does
                 what it claims to do. -tien
        \_ Yes. Every tree-hugging American can stop Valpak and save the
           earth! Every little bit helps!     Delusional crack-heads.
           The Earth is doomed so long as humans exist. Period. The only
           enviromentally-friendly move you can make is the one no beatnik
           voluntarily does - commit suicide or at least get neutered.
           \_ Suppose that you're an Orc, who lives in Mordor, and you hate
              trees and all green growing things, and you want to Middle Earth
              burn under a thousand years' of sooty flame.  Wouldn't junk
              mail still piss you off?  Wouldn't it bother you just a tiny
              bit when that big envelope you're hoping is a promotion from
              the Dark Lord turns out to be another ad?
           \_ Sure let's all drive SUVs and reproduce 8-12 kids a family.
              While you're at it why don't we all smoke and drink till we
              die early so that we will stop polluting the earth. Hell
              why not drop the bomb that we'll all stop polluting. Fuck
              the earth. Whatever, you fuck tard.
           \_ Not making more Americans is probably the most environmentally
              conscious thing someone can do in this country.
              \_ explain that to the Republicans who over-reproduce the
                 Democrats by almost 2 to 1
              \- i came across this interesting [assuming true] statistic:
                    We use about one-sixth of our electricity to cool
                    ourselves. That's more than the total electricity
                    consumption of India ...
                 \_ So what?  The only bad thing about it is that we're spewing
                    hazardous byproducts.  If we can just figure out how to
                    produce the energy in a manner which is only hazardous to
                    ourselves, there's no problem.  Clean production is a much
                    bigger long-term win than conservation.
                    \_ One could even argue that the SUV driving republican
                       morons are actually helping develop clean production,
                       since they'll raise the profitability of sustainable
                       production by bringing the crisis on sooner.
                       \_ One could argue that, but one would sound like a
                          complete idiot.  -tom
                          \_ Hypothetically, if one were to sound like a
                             complete idiot, one would have come to the
                             right place posting one's arguement on the CSUA
              \_ its not really an issue of not making more americans -- US
                 population growth would be stagnant if not for the immigrants
                 (thats another story).  The real huge problem is all the other
                 countries who are trying to be like americans.  The
                 modernization of the third world and all.
                 \_ Hence the need to kill everyone. But no one wants to
                    start with themselves. Yes, you'll say why don't I.
                    But I'm not a hippie-commie. I'm damn glad to be popping
                    out as many kids as I can.
                    \_ thats no solution. The people who are willing to kill
                        themselves die, leaving the problem people behind to
                        reproduce at will and muck things up.  You have to
                        kill yourself in the process of killing many others.
                        \_ Durka Durka Eco-Jihad!
                        \_ Knowing this, you should not kill yourself. The
                           problem people reproduce much faster than you can
                           destroy them. Eventually their police-state
                           apparatus will eliminate you in your work.
                           Our best hope is a biological superweapon a la
                           12 Monkeys. Our research is promising my brothers.
                           \_ Or you can sit in your windowless basement room
                              with the lights off watching 12 Monkeys until
                              you no longer care.
                   \_ Immigration & the modernization of other countries are
                      not things I have direct control over.  Not knocking
                      someone up is something I have direct control over.

8/9     Linux question.  We have a simple server that recieves TCP/IP
        connections concurrently with a threadpool, creating new threads
        as necessary.  It's showing a weird performance quirk where, if
        you increase the number of concurrent connections, the connection
        time increases slowly, from .1s.  At 16 connections it's
        about .2s.  However, the 17th connection takes 1.2s, a large
        jump.  The connection times continue increasing slowly from
        there, although there are little jumps at 48 and similar
        multiples of 16. slowly.  Is there some magic kernel number 16,
        above with establishing a TCP/IP connection takes a long time?
        \_ Stupid question, does your threadpool have a max number of
           \_ Yes, but it's 1024, which is actually higher than the kernel
              seems to be able to generate.
              \_ Java threads?  pthreads?
                 \_ pthreads, it's all C or C++ code on chaos Linux,

8/9     Poll, what do you personally do to help the environment? Recycle?
        Planting trees? Ride a bicycle? Nothing?
        \_ I pull out so that I don't over-reproduce more kids who'll
           pollute the earth.
        \_ I live my life the way I like it, because I simply don't give a
           damn about you hippies. Global warming is not going to affect
           me before I die.                     -Republican

        \_ I strictly adhere to Al Gore's example.  He leads.  I follow.
        \_ I don't drive a Hummer. In addition I'm living in a cramped home
           instead of a luxurious suburbian home that is far away.
        \_ I could go on about how I don't own a car and how I bike
           "everywhere", but I think i use as much oil for my plane travel
           as a typical car commuter.  How do those compare anyway?
           \_ do you think car commuters don't travel by plane?
              \_ not really.  that's why summer auto use sky rockets from
                 all the SUV driving, 8 kids having, mouth breathing, red

                 staters don't have summer travel plans and don't fly either.
                 \_ plane use also skyrockets in the summer.  Are you really
                    this dense?  -tom
        \_ I drive a Chevy Suburban instead of a Hummer, thus saving lots of
           gasoline. I hate Hummers.
           Seriously though, I don't find myself polluting as much as say,
           the people in Brentwood or Beverly Hills for the simple fact
           that I can't afford expensive stuff that tend to pollute, like a
           Porsche, a big house, nice clothes (that use up more packaging and
           more material and require more shipping), etc. My guess is that
           the amount of pollution one emits has some tendency to do with
           one's personal wealth. There are always exception of course so
           I'm speaking in terms of averages.
           \_ Are you out of your mind? Expensive clothes likely pollute
              less. In fact, I would guess that the wealthy tend to
              pollute less when comparing like items, because they can
              afford to buy organic, natural, and so on. They can afford
              to maintain their cars and/or buy new ones with lower emissions.
              In short, they can afford the added expense of reducing
              pollution. It's the poor who cannot afford to. They are the
              ones driving that 1969 Impala smoking on the freeway, buying
              clothes made of oil, and eating $1 double cheeseburgers
              which are contributing to global warming and the destruction
              of rain forests in South America.
           \_ What's the gas mileage of your Chevy Suburban?
              \_ 6.9 miles per gallon on surface streets. --proud American
        \_ Commute by bus from Union City to Foster City.  Bring my own bags to
           grocery stores.  Recycle (as a third resort after Reduce and
           Re-use.)  Power-off my machines and monitors when leaving work.
           Take the stairs instead of elevators.  (It happened that a PG&E
           energy audit at my company found that the elevators are the #1
           energy hogs in the company.)
           \_ Machine(s)?  Monitor(s)?  Only powered off when leaving work?
              Why do you have multiples and why do you only power off when
              leaving work?  Do you power off everything when you go to
              lunch?  Meetings?  When someone stops by to chat for a few
              minutes?  How much of Gaia's life force do you murder every
              day chattering away on soda?!  Have you sterilised yourself
              or taken a vow of abstinence?  Have you signed a blood pact
              to kill yourself when you're no longer carbon neutral?  You
              could be doing so much more!  Well at least you bring your own
              bags to grocery stores.  That helps a lot.
              \_ I have multiple machines because I need multiple machines to
                 do work.  (VM doesn't work.)  Sorry, I lied about monitor*s*.
                 I actually only have one.  How do I do work if I power off the
                 machines while I'm working?  I don't "go to" lunch because I
                 eat at my desk.  I do power off the stuff when I go to
                 meetings.  -- PP
                 \_ Have you been sterilised yet?  Taken the carbon neutral
                    blood oath?
                    \_ Did you kill yourself and rot so as to contribute your
                       carbon to the environment?
           \_ Holy CRAP!!!  I find this fact about elevators extremely
              suprising.  Are elevators no longer run off of a counterweight?
              I would have though that because of the counterwieght, the amount
              of work done would only be that required to lift your body, which
              shouldn't be much.
              \_ Accelerating the elevator cage, the counter weight, and the
                 passengers (if any) from zero requires energy.  I guess
                 elevators don't have regenerative brakes, so you don't get
                 the energy back when decelarating.  The bigger the elevator,
                 and the higher the speed it travels, the more energy it
                 consumes.  -- PP
        \_ I intentionally bought a home three miles from work, in a
           walking district.  I've been car-free for over 15 years.  We
           have a 3KW solar electric system which provides all our power.
           Plus lots of feel-good fairly meaningless stuff like recycling. -tom
           \_ All your power?  So I assume you store power in a battery array
              for night power use?  How big is your battery array?  How much
              area does your solar collector take up?  Where did you go to
              start learning about this stuff when you first decided to do
              it?  thanks.
              \_ Don't know what his setup up is, but most people stay
                 connected to the power grid and use something called
                 "net-metering".  Basically you can produce more power
                 in the day time and put power back to the grid (and
                 the meter spins backwards).  During night time you
                 use power from the grid.  If you size you system right,
                 you can essentially have net grid usage of zero.
                 \_ Exactly.  We are still grid-tied, but for the year we've
                    had the system, we've generated more power than we've
                    used.  Unfortunately, with time-of-use metering they
                    need an electronic meter, so you don't actually get to
                    see it spin backwards; we did see that for the first
                    month we had it installed.  -tom
                    \_ If you don't mind saying, how much did the system cost
                       to get installed?  How long is it expected to last
                       before requiring maintenance or replacement?  Thanks.
                       \_ After discounts and rebates and such, it was about
                          $18K.  Maintenance should be nothing more than
                          cleaning the panels once or twice a year.  Most
                          of the components are rated for 20 years and will
                          probably last longer than that: it may be
                          economical to replace them at some point, depending
                          on what happens with solar technology over the
                          next 20 years.  -tom
                          \_ Not bad.  I figured your break even point is about
                             the 12 year mark guessing you're using an average
                             of $200/month in electricity.  Unfortunately, the
                             rebates and breaks aren't that big anymore so a
                             similar system now costs over $30k which means it
                             isn't possible to break even in the 20 year life
                             span of the system.  I assumed a 4% rate of
                             return on your money and zero cost/profit on your
                             electric usage over the 20 years.  If I could get
                             one for $18k I'd probably do it.
                             \_ I think the break-even point is a lot sooner
                                than that, because the solar system increases
                                the value of the house.  Maybe not by $18K,
                                but certainly by an appreciable fraction
                                of $18K.  -tom
                                \_ I thought of that but to get money back that
                                   way you'd have to sell.  The closer you
                                   sell to the 20 year mark the less the system
                                   is worth.  If you sell earlier then you
                                   don't get the full benefit of having it.
                                   Also, I'm guessing it really doesn't add
                                   that much anyway.  For example, having a
                                   pool doesn't add anything to a house.  Some
                                   people want one, some people hate them, so
                                   your potential buyer base drops and overall
                                   a pool generally adds zero.  Anyway, your
                                   18k is a good price and you'll make it back
                                   by any reasonable numbers before the 20
                                   year mark.  Pricing is higher now so that
                                   is no longer true for new units,

                                      implausible that anyone would reject
                                      a given house because it has a solar
                                      system; it's an improvement like
                                      new plumbing or central heating which
                                      will consistently be viewed as adding
