  1. Metric is Better, but not Best on The Logic Behind Metric Paper Sizes · · Score: 1

    While metric(SI, or MKS, standing for meter, kg, seconds) is much better than American^H^H^H^HEnglish units, it is obnoxious to use because there are all sorts of conversion factors like mu and epsilon that you have to use when dealing with things like eletricity and/or magnetism. CGS (stands for cm, gram, seconds) is much better in that converting from one unit to another never require a numerical factor. Something that is kinda funny: astrophysicists use centimeters and grams to describe astronomical distances and masses. Just a thought, though I am not sure how this relates to paper sizes.

  3. The Solution on Intel Chief: Don't Call Us Benedict Arnold CEOs · · Score: 3, Interesting

    Convince shareholders to outsource CEOs from (Santa Clara) California wiith a high cost of living to somewhere in Kansas, just to show them that the real way to increase company profits is to pay CEOs a reasonable amount of money. Maybe then those CEOs would be nicer to their employees here in America (I'm sure companies in Europe could do the same thing) not to mention fewer CEOs with ridiculous amounts of money.

  4. WordPerfect and OOo on OpenOffice.org, MS Office 2003 Compared, Evaluated · · Score: 1

    My problems with OOo:
    1. No native OS X port.
    2. No reveal codes.

    If OOo had EITHER of those two things, I would use it. But it has neither and as a result, I use TeXShop (yet to learn LyX) for anything official or formal, and TextEdit for the rest. But then, I've never used MS office, it was always WordPerfect (and I am longing for a Mac/Linux version).

  5. Re:People like sitting in the same place on People Feel Loyalty To Computers · · Score: 4, Interesting

    At Caltech, we have sit-down dinners that are waited by students. Recently thought, Dining Services introduced the possibility of eating elsewhere once a week so often fewer people come to dinners. As a result, on these nights of low attendance, we pick a couple of tables to not set. It is really much fun to watch the people who always sit at these tables go "Ah! My seat!? Where do I sit?" On the other hand, it easier to wait if you know where everyone is sitting because you don't need to wonder where to find someone.

  6. Re:QM Mechanical limit on Data Transfer Has A Speed Limit · · Score: 2, Informative

    First, you don't understand anything about quantum physics or you would have included a greater than sign instead of an equal sign. Second, I have only taken a term on it, but looking at what your wrote...it is completely wrong. Here is what I know to be true about the uncertainty relation:

    1. del-x*del-px>= hbar/2 (uncertainty in position times uncertainty in momentum is greater than or equal to hbar over 2 (or h over 4pi))
    2. del-E*del-t>=hbar (uncertainty in energy times uncertainty in time is greater than or equal to hbar (h over 2pi)).

    Note that the definition of del-q (where q is any measureable) is |^2-| where is the expected value of r (requires an integral which I am not going to try to type here). Using this paragraph, any ambitious individual can derive Heisenberg's Uncertainty Principle, which is not what you have. Furthermore, because you have d instead of del, you get that dE=h*df while del-E does not equal h*del-f but h^2*del-f.

    Finally, you forget that you can overlap frequencies and then compute the composite frequencies by doing Fourier Transforms. This fact alone drasticly increases the amount of information that cane be transmitted if the sender and reciever agree to use a set couple of frequencies.

    I think I got everything. I also made sure that when I wrote the above that I eleminated all errors. However, if you measure the energy and then try to measure the position of the 0s and 1s again you will recreate the wavefunction (destroying the eigenstate) and then possibly introduce errors into my post!

  7. Yes. on Data Transfer Has A Speed Limit · · Score: 1

    The particles may be in the same state but that in and of itself does not transfer any data. You need to send some data the old fashioned way in order to actually do anything with the quantum entagled particles (ie. say if the quantum bit is the same or different).

  8. Re:Claremont Colleges on Intel Ranks Colleges with Best Wireless Access · · Score: 1

    So I posted another comment, but I will repeat some of it here for you: surveys are retarded and require people with free time to fill them out => no Caltech responses, if Intel even solicited any. My reasoning is because Caltech has a pretty good wireless setup especially if you include the student's personal APs in the houses (institute owned dorms, only cooler).

    And on an offtopic note: it is Caltech, not CalTech.

  9. Caltech on Intel Ranks Colleges with Best Wireless Access · · Score: 3, Interesting

    So the problem with surveys is that they require people's time to respond. For example, when I was a frosh the Princeton Review or someone conducted an online survery and one of the questions was about workload/free time. Now, if you think about it there are likely to be some freaking brilliant people that will say that they have plenty of free time and the work load isn't hard. Meanwhile, the other 99% of us aren't bored enough to fill out the survery. As a result we were ranked really low on the workload that year. And believe me, this week was the first week I've ever had an easy problem set (it took only 3 hours).

    So back to the topic, where is my school? We have wireless in most of the lecture halls and some of the newer classrooms. It's not great but its good for simple browsing/IM/e-mail. From the way that you describe the wirelesss there, I would think that Caltech should be higher than "not on the list." There is none as of yet in the houses (not frats, campus owned dorms, but cooler) but that is because they are old Faraday cages that are going to be rebuilt so current wireless is student owned access points. So why the institute doesn't provide them, I can walk from one side of my house to the other and have access the whole time, switching from AP to AP.

    In other words, the wireless access here is good in my opinion and surveys are pretty crappy means of advertising.

  10. Re:online search world == interesting? on MSN Rolling Out New Search Engine In July · · Score: 2, Informative

    So in my opinion there are 3 good websites on the internet:
    E-Print Archives
    Mathworld and Scienceworld
    Federation of American Scientists

    Of the three, 2 are distinctly not for profit, but rather so that scientists can get some work done again and who know's why wolfram put mathworld and scienceworld online. As far as more liberal arts stuff, the only online thing I know of is jstor.org and I think that might require paying for, but my university pays for it if it does. I found all those sites very useful and suggest that you check them out if you haven't already done so.

  12. Re:Come on CA on City Officials Almost Ban Foam Cups · · Score: 2, Insightful

    I disagree with your analogy that "expecting perfect decision-making 100% of the time from leaders is akin to expecting coders to write non-trivial code that works perfectly on first execution." IMO, expecting decent decisions from leaders is akin to expecting decent code in final products that go to market. I don't care if you code doesn't work the first time, it's just a draft. What I care about is the final product of both cases, and being educated enough to not waste ones time working on drafts of stupid things (sorry, I can't think of an analogy to coding here).

  13. Re:Comparisons with macs? on Sharp Debuts New Transmeta-based Laptop · · Score: 2, Interesting

    Contrary to the other replier, I have a 15" G4 Powerbook (TiBook) and I still get a little over 4 hours on the battery if I turn down my screen a little bit (still very readable). I would also like to mention that my powerbook is over a year old now and it got more than 4.5 hours when it was new.
    As for the newer powerbooks, I can't say how they compare, but its probably pretty close to 4.5 hours if that is what Apple claims. The 17" powerbook has a bigger battery and so it should last about the same as the 15" while the 12" lasts longer at over 5 hours (my friend's would last about 5.5 hours).

    As for the G3 laptops.....those are old stuff man. Apple stopped selling them so I can't even check on the specs for you.

    As far as the heat issues go, I can heat up my lap if I (simultaneously):
    1. Tell Mathematica to sum a series from 1 to 100 with many factorials and an infinte sum inside.
    2. Burn a DVD.
    3. Read slashdot over a wireless connection in addition to being on IM, other standard things, etc.
    But I still won't get anything near the 2nd degree burns you get with my dad's P4 2.4 GHz Toshiba.

    In other words, I love my powerbook. =)

  15. Re:i do have a choice on Microsoft Unhappy With HP's iTunes Decision · · Score: 2, Interesting

    "We expect competition and it's good for customers. Over time, however, customers will want industry standard choices.'' Translation: We will force "industry-standardized" choices down their throats no matter what the competition tries to feed them. It seems that Dell is becoming more and more of Microsoft's puppet. On another note, isn't the fact that HP is coming out with something to work with iTunes proof that this statement was made by an ignorant fool: "General manager of Microsoft's Windows digital media division David Fester has suggested that iTunes' emerging dominance would be bad for consumers, because it would limit them to the iPod."
