  2. Re:Most of you missing the point. on Trigonometry Redefined without Sines And Cosines · · Score: 1
    I have developed the habit of always using complex exponentials instead of trig functions when doing calculus or when multiplying trig functions.

    That mainly because I don't like memorizing redundant stuff like sinx*cosx identities.

    That's because 2003 is a server only release and only very few use (pirated?) copies on their home box. 2003 would have made an excellent update to XP though..

    If AM was officially refered to as "Medium Wave", too, in addition to Medium Wave being called Medium Wave, then maybe.

    That's just not true. GSM is not being replaced by CDMA-the-phone-standard, which is pretty bad. The thing is, there is a transmission standard which is *also* called CDMA, but is something quite different.

    It's true that CDMA-phone-standard also uses CDMA-technology, but UMTS is based on GSM while also using CDMA-technology.

    Kind of confusing... I just found this in an old ./ comment, though:

    CDMA is both a mobile phone standard (IS-95) and a technology (Code Division Multiple Access) and if you're comparing "GSM" to "TDMA" to "CDMA" then you're refering to phone standards. CDMA the phone standard is junk, in all honesty, and is being phased out. The direct replacement for it is CDMA2000, which existing US IS-95 operators like Sprint PCS and Verizon are moving to.

    CDMA the technology is rather better and is being used in a number of newer systems. GSM "version 2" is called UMTS, and has a configurable air interface which can be GSM's Time Division Multiple Access, EDGE (a more modern and efficient Time Division MA system), or a variant of Code Division Multiple Access (ie the CDMA the technology, not CDMA the mobile phone standard) called WCDMA, depending on the operator's preferences.

    Only CDMA2000 is based upon CDMA the standard. UMTS is based upon GSM. TD-CDMA is a completely new system and isn't based upon anything. It does use "CDMA the technology", but it certainly isn't related in any way, shape, or form to IS-95

    Not quite.. Momentum is conserved, i.e. m_iss dot v_iss + m_garbage dot v_garbage = const.

    You can figure the different scenarios out from there on... If the garbage's mass is equal to the space station's mass, then indeed you'd have quite a noticeable effect on the station trajectory.

  7. Re:Missing even more... on New iBook and Apple mini · · Score: 1
    I've just bought a 1.67 GHz G4 Powerbook a few weeks ago and I don't really understand what all the complaints about not getting a G5 are all about.


    My Powerbook has almost replaced my P4 3GHz desktop in the meantime, because it doesn't *feel* any slower for pretty much everything I need it for (I don't do any video editing or gaming, I do use resource intensive scientific software though).


    I don't think that a G5 processor would actually change things fundamentally (apart from the fact that it would be new and cool).

    95% of all computers have a USB port, but only 50% have a CD drive, according to your made-up numbers?

    I don't think so. A bootable CD is still a much safer bet e.g. for emergency recover issues, especially because booting from CD drives is better supported on older hardware than booting from USB devices.

    The most important reason I can think of that still matters today is when you want to use a video projector.

    Most of them require you to set your VGA output to 1024x768 at 60Hz... I'd hate to have to start playing with my XF86Config a few minutes before I have to give an important presentation.

  10. Re:Tensor analysis on Science's 125 Big Questions · · Score: 1
    All dimensions are real (i.e. not imaginary) in the newer literature. Of course, that's just a convention, but as far as I know most people nowadays use the (ct, x, y, z) notation instead of (ict, x, y, z).

    By the way: Note that the zeroth component that represents time has the dimension of a length, so time and space really are treated the same in special relativity (I'm not sure about GRT, but I suppose that that holds there, too).

    What is still a bit weird about the four-dimensional Minkowski space is that it has a slightly different metric than our normal 3-space: The metric tensor is not all positive but puts a negative sign in front of the space components (again, that's just a convention, some people use a negative time part and leave the sapce part positive; it doesn't matter).

  11. Re:How about... on Nokia And Apple Collaborate On Open Source Browser · · Score: 1
    I'm a bit tired of reading that exact same comment every time a story about cell phones comes up..

    There are quite a few phones that only have the basics and are really good enough for what a phone should be good at, that is placing and receiving calls and maybe texting.

    It is just that the flashy shiny phones with cameras are advertised more because some target consumer groups (=teenagers) like to spend money on useless things.

    That's not such a good idea. There are lots of libraries that are shared between programs but wouldn't still be considered a part of the operating system... What about those? Imagine having a libpng.so in a few dozens program packages and then having to replace each and every instance when a security vulnerability is discovered. I do agree that keeping most of the files an app needs in a seperate directory is not a bad idea, though..

    Exactly. Lots of people have no idea what college-level physics is really all about and when they say "Physics would be the right thing for you" they actually mean "Engineering"... Physics is so beyond real-life problems practically and considering the math required that having a physicist work on a game-physics-engine would be like having an MD design a Little Doctor Kit (tm) for Toys'R'Us. Also, physics is really difficult, arguably more so than CS.

  20. Wait a minute.. on German Court Sets Copyright Tax on New PCs · · Score: 3, Informative
    Now, before anyone gets any wrong ideas here and stars complaining about music, independent labels etc:

    VG Wort is not about music. VG Wort is responsible for collecting money on written documents / books and the rights associated with them. And they are right about wanting to get that levy on computers, because people who want to set up Xerox machines and use them commercialy have had to pay that levy since, eh, always (And thereby you have the right to copy material out of books without owning the books).

    So yes, you have to pay the levy, but you are also allowed to make non-commercial copies of books / magazines etc because of that. Stop complaining.
