12/15   I'm planning on traveling to Europe and I was wondering if there's
        any reason I shouldn't be able to use a US power tap/strip (no surge
        suppression) with just a plug adaptor (i.e., no voltage conversion).
        This would be for use with electronics that accept 100V-240V. While
        the power strip is intended for use at 120V, it's just wires, right?
        (Also, this power strip has no power LED or similar.) If anything,
        my understanding is since US voltage is lower, the wires generally
        need to be heavier gauge, so Europe shouldn't be a problem.
        Am I missing something? If so, what do you guys do when traveling
        to countries that use ~230V power? Thanks.
        \_ if that power strip has any form of surge protector in it, that
           will blow the first time you plug it into 240V.  Other than that
           you'll have to deal with different outlet format.

4/26    Many thanks to the current generation of CSUA membership for throwing
        the alumni barbeque this weekend.  The current generation seems like
        a smart enterprising bunch.  Good to know that the CSUA is in good
        hands. -dans
        \_ ...unlike when dans was involved.
           \_ You're right it was so much better when it was run by curmudgeons
              and anonymous trolls. -dans
              \_ like paolo?  -tom
                 \_ Your familiar, albeit mostly recycled, trolling is vaguely
                    comforting.  Good to know that some things about the CSUA
                    will never change. -dans
        \_ wow awesome gratuitous insult there.  dans i didnt see you there,
           did you not stay very long?
           \_ I was there a little before the barbeque, but had to leave
              around 2:30 to go to a flame effects meeting for the art project
              I posted about above. -dans

        San Jose and San Francisco... not a surprise. Northern Cal
        is still the best place to live.
        \_ What are you talking about? San Jose was 6th (above SF) and
           SF was 15th. If you rate "best place to live" as "best place
           to find a job" (which I don't) neither of these qualify and
           the answer is Washington, D.C.
           \_ it's a shitload better than Los Angeles, which is full of
              lame IT and support jobs. There are no real tech jobs that
              require real education. LA only needs people who have bullshit

7/21    Quasi Science Question:
        Is running a high ethanol mix going to mess up my 4 banger?
        Also, why do people hate on the eth?  At $2.11/gal it's kinda
        nice, i didn't notice any pings.  - Des Moines CSUAer.
        \_ 2.11 is what you pay for it (maybe) but it isn't what WE pay
           for it.  What's the subsidy per gallon?  What's the cost
           per mile?  Also, I think the majority of hating is reserved
           for corn ethanol.
           \_ from Iowa, i would have to assume that's corn ethanol
              why the hate on corn? is it just the subsidy?
              \_ Corn is a very inefficient producer of ethanol.  -tom
       \_ assuming that's pure ethanol that works out to about $4.00
          per gasoline gallon equivalent (again not counting subsidies)
        \_ EtOH doesn't have as much energy per unit volume, so you are
           not getting as good a deal as you might think.
        \_ Ethanol also burns hotter than regular gas, just check your
           oil over time, you will experience some decay faster than normal.
           Also, unrelated issue but I will assume you might have a boat:
           (or more likely don't consume an entire tank of gas in 3 days).

5/18    Does the new federal vehicle fuel-efficiency requirement specify how
        efficiencies of plug-in hybrids will be calculated?  Some plug-in
        hybrids claims to have ridiculously high efficiency like 100mpg because
        they're not counting the energy input from the electric grid.  That's
        not a good indiction of their actual energy efficiency.

4/3     My friend keeps trying to get me to buy Silver as it's $13/oz while
        gold is around $900/oz which is a huge disparage considering the
        comparative rarety of silver and it's industrial uses.  He thinks that
        the current price is artificially kept low.  Anyone know anything about
        these claims?  Most of the places he points me to sell silver and gold..
        \_ Precious metals are a hedge against inflation.  There's really no
           difference between silver and gold except the price/oz and that gold
           doesn't tarnish.
           \_ The belief is that silver will be worth closer to gold.  And it's
              the copper in sterling that tarnishes, fine silver or argentinium
              hardly tarnishes at all.
              \_ Could be. Could also mean gold prices will fall. Why didn't
                 he buy silver when it was $4/ounce not that long ago?
                 $13/ounce is not all that cheap.
        \- your friend's reasoning is stupid. i would avoid discussing
           finances with him.
           \_ Second what this guy says.  The valuation on both gold and
              silver is more psychological than it is driven by industrial
              use.  Can you predict when the herd will abandon gold/silver
              like when the herd abandoned the stock market?  If so, then
              you can make money on ANYTHING.  If not, avoid bubblicious

2/15    How many watts does a typical desktop (not counting monitor)
        use when it is completely idling (top shows at most 1-2% CPU),
        assuming normal SATA HD, video card, 2-4G RAM?
        \_ Google did a published study where they determined that the
           largest consumer of energy in a computer is the power supply
           itself. Figure that if you have a 400W power supply you are
           using at least half that if not more even when idle.
           \_ that totally blows. Laptop #1!!!
              \_ Power supply manufacturers need an incentive to make more
                 efficient power supplies. It's probably not hard to do.
                 Google was talking about pushing manufacturers on that
                 issue, but one company is probably not enough.

9/22    Gmail's "conversation feature" drives me nuts! Is there a way to
        disable that and make Gmail act like every other e-mail client on the
        planet? WTF thought this was a nice thing to have on by default?
        \_ Umm, why don't you just use another email service then...
           \_ Umm, I do, which is how I have something to compare to. I get
              mail in at least 4 places only one of which is Gmail. I
              rarely use my Gmail account, but I decided to try it again
              today just to see how it was running and what features it
              has added. I like to stay current with this stuff for the
              same reason that people have accounts on flickr, snapfish,
              photobucket, and shutterfly. This "feature" of Gmail annoys
              the crap out of me.
              \_ Well, it is kind of central to their design of the product.
                 So if you don't like it and can't deal with it, use something
                 else. This need to "stay current" with different email
                 services is also somewhat mystifying. Do you like to
                 "stay current" with different word processors too? I mean,
                 there is some benefit to being familiar with whatever, but
                 it seems like there are many more worthwhile things to spend
                 your time learning.
                 \_ That's nice. I run Windows, Mac, and Linux but I guess
                    some people just learn Windows, are happy with it, and
                    that's that. So, yes, I do use different Word
                    Processors (OpenOffice and Word), mail clients (,
                    Thunderbird, kmail, and Outlook), etc. You might find
                    you like to watch TV, golf, or whatever your hobby is
                    that I find a waste of time. If you learn C++ does
                    that mean you shouldn't spend time learning Java or ruby
                    or python or whatever even if it turns out you think the
                    language sucks once you invested time in it?
                    \_ So a mail program is like a language?  "Keeping
                       current" with gmail means figuring out all the cool
                       things they do with javascript.  It doesn't mean knowing
                       how to read your email.
                       \_ I think you are wrong here. There are features
                          that can make you more productive if you know
                          about them. If you know "vi" then why learn
                          "emacs"? You already know a text editor, right?
                          \_ If you need to "stay current" with mail readers
                             you aren't smart enough to stay current.  It's
                             a flipping mail reader.  It reads mail.  A
                             moron can figure it out within 10 minutes.
                             \_ Spoken like someone who doesn't know very much.
                                "It's a friggin text editor. It edits text. A
                                moron can figure it out within 10 minutes."
                                Point here is that you don't know what
                                features are available until you spend
                                that 10 (or whatever) minutes trying it out!
                                \_ You keep that "gmail power user" on your
                                   resume.  Let us know how it works for you.
                                   \_ Keep reading your e-mail using PINE and
                                      let me know how it works out for you.
                          \- what is weird are the people under say 30
                             who learned vi rather than emacs.
        \_ Options -> sign out of chat.
        \_ There doesn't seem to be any way to turn it off.  It drove
           me crazy at first, but now I love it.
           \_ Same here.  At first I hated it, now using my yahoo account
              feels like going back to elm.

7/5     Just saw Wall-E.  Beautiful movie.  Environmental message was vague
        enough to appeal to anyone.  "Stay the course" was a bit heavy-handed.
        Overall, thumbs up.
        \_ I totally agree, it was very nicely done.  If the stupid right-

                       when I told her (a few weeks before she was getting
                       married) that marriage required giving up some of that
                       'me, me, me' to make room for 'us, us, us'.  She's
                       still married 3 years later but they're both miserable.

                          That always makes people happy! I think most
                          people on the MOTD are idealists who never
                          encountered real marital problems but, more
                          likely, just delude themselves into thinking

                             politics and eschewing the latter.
                          \_ Not for the sake of the marriage, per se.  And
                             not thing you don't want to do.  But you do things
                             because it makes your wife happy and she does the
                             same for you.  A trivial example: my wife does
                             99% of the house work.  Sometimes she's tired or
                             just doesn't feel like it so I offer to do it.
                             I don't *like* doing housework but it isn't that
                             big a deal and it makes her happy that I'd do it
                             sometimes without being asked (much less nagged).
                             Was that a sacrifice on my part?  Sure, sort of,
                             but not really in the long run.  What sort of
                             sacrifices did you have in mind?  (And please note
                             that I did say this was a trivial example).

                                   recently.  When she did we had a maid
                                   service and split the rest of what the maids
                                   didn't do.  I hauled trash, we split the
                                   dishes, she did most of the laundry, etc.
                                   \_ I was wondering where you found someone
                                      who thought doing 99% of the housework
                                      was equitable. Now I understand. My wife

5/7     A typical house is responsible for the emission of more than three tons
        of carbon annually, compared with about 1.5 tons for the typical car,
        according to the Environmental Protection Agency.
        \_ So, if you and your family spend 2/3 of the time at home
           and 1/3 of the time in your car, both are about the same,
           eh?  What a stupid comparison.  Still, I do believe homes
           in CA are horribly inefficient.
           \_ New homes in CA tend to be very energy efficient.  Where'd you
              get the idea otherwise?
           \_ Not only that, but since the climate is so mild in CA, homes here
              probably use far less energy for air conditioning and heating
              than avg.
              \_ While new homes tend to be more energy efficient they also
                 tend to be bigger.  It's also pretty easy to take an older
                 home and make it efficient (double pane windows, better
                 insulation, these things aren't that expensive).  Plus
                 newer homes are more likely to have AC even in climates
                 like the Bay Area where really you don't need AC.
                 \_ I've lived in some old houses and no, slapping on double
                    panes and some fiber glass isn't going to help compared

                    turning on the AC.
                    \_ You turn on the AC at 85?  Generally I find that just
                       getting cool air into the house at night will keep
                       the house cool enough during the day up to 95.

3/15    According to ABC, 90% of the energy used by incandescent bulb is
        wasted in heat.  That mean only 10% of the enery it takes in
        outputs useful light. In addition compact flourescent light takes
        about 1/4 of the same energy for the same output. So let's suppose
        I have a 25W compact flourescent bulb and outputs as much as a
        100W incandescent bulb (or 10W of useful light). Can I safely
        assume the compact flourescent bulb also outputs 10W of useful
        light and 15W wasted in heat, or 10/25 (40%) efficiency?
        \_ I'm sure that will make a major diff. in 'saving the planet'
           Of course it won't. The only real way is population control.
           \_ 36 years old and no kids yet.  Can I have a tax break?
        \_ of course in winter, the 'heat' isn't wasted.
           \_ Yeah.  But in summer, not only is the heat wasted, it makes your
              AC work harder which takes even more energy.
           \_ not entirely -- except when you consider the energey used to
              generate that electricity in the first place.  Usually generated
              by some form of heat engine, again usually burning fossill fuels.
              So that 90W of electrically-created heat required the waste of
              another ~200W of heat at the power plant.  Compare this to
              burning gas locally to generate heat, where virtually all the
              heat in the gas goes to heating.
              \_ totally agree. But neither heat nor power generation is
                 factored into light bulb efficiency anyways -pp
           \_ Yeah.  But household furnace usually burns natural gas.
              Burning gas to generate heat is more efficient than burning gas
              to generate electricity and then using electricity to generate
              heat, which in turn is cleaner than burning coal to generate
              electricity and then using electricity to generate heat.  Also,
              in summer, not only is the heat wasted, it also makes your AC
              work harder which uses even more electricity.  That's the same
              reason why, if you leave your PC and monitor idling at, say, 20W
              in an air-conditioned room, you're actually wasting more than
              in an air-conditioned room, you're actually using more than 20W.
