  1. GarageBand on Apple Introduces Logic Pro 6 and Logic Express · · Score: 1


    I have been waiting with great anticipation for GarageBand to arrive and after a night of playing with the program, I can say that it does not disappoint. It's 3:30 a.m. and I've just finished up my first two songs.

  2. GarageBand on Apple Justifies iLife Price Tag · · Score: 1


    I attended MacWorld in San Francisco a week ago and was able to demo the new iLife applications first hand. When I returned home that evening, I immediately went to the Apple Store and purchased iLife. While the incremental upgrades certainly justify the cost, the reason for the immediate purchase was special.

    What is so special? GarageBand!

    I've been looking for a similar program on MacOS for about a year and have been frustrated to find that they typically cost hundreds of dollars. Now apple releases GarageBand for a fraction of the cost and they throw in improvements to all their other applications. As a music enthusiast with beginer's skills I cannot wait to make my own music tracks using prerecorded loops and my own samples.

    I left MacWorld not questioning why they would charge for iLife but wondering how they can afford to put out such high-quality software at such a low price. (My guess is subsidies from their hardware.)

  3. tar sun4u sun4m on What is the Worst Tech Mistake You Ever Made? · · Score: 1


    I was a newbie sysadmin who didn't fully grasp the concept of the tar command. I untared an entire /usr/X11 directory ontop of an existing /usr/X11 directory. The painful part was that the distributions were binary incompatible -- one was compiled for sun4u processors and the other for sun4m processors.

    I knew I made a mistake when exclamations, gasps, and quizzical mutterings began to fill an otherwise quiet graduate laboratory. Before I had a chance to fully grasp what I did, my three supervisors walked in the door, having seen my command scroll across their syslog terminals.

  6. Re:Rotational Kinetic Energy II on No More Leap Second? · · Score: 1


    I disagree totally. A first-order approximation is a first-order approximation. Additionally, there really is no other way to come up with an off-the-cuff, order-of-magnitude estimate of rotational kinetic energy. Aside from writing a finite element code to simulate the fluidic mantle, you're stuck with an algebraic or calculus-based approximation.

    Further, it seems nonsensical to state that the "approximation is such to prevent its use here", when there exists no other easily accessible approximation and "here" refers to slashdot where the required accuracy is zero.

    If I were paid to solve this problem, I would next bound the minimum and maximum total rotational kinetic energy assuming ideal flows with and against the rotation of the crust to bound the solution (leaving algebra behind for simple calculus). I fully expect that the first-order approximation would lie between those bounds.

  8. Re:Rotational Kinetic Energy II on No More Leap Second? · · Score: 1


    I know that the Earth is an inhomogenous oblate spheroid with a fluidic mantle, however closed-form algebraic equations to estimate the rotational kinetic energy of such a structure do not exist. Thus, I used an approximation (note the "if A is assumed to be B" clause).

    Although it is just an approximation, it nonetheless provides the order-of-magnitude energy that is either stored in the Earth's mantle or transfered to the Earth-Moon system. I just thought this would be understood.

  9. Rotational Kinetic Energy II on No More Leap Second? · · Score: 4, Interesting


    If the Earth is assumed to be a homogeneous sphere and the rotational axis is assumed to be the straight line passing through the north and south geographic poles, the moment of inertia of the Earth is I = MR^2 where M is the total mass of the Earth and R is its radius. The kinetic energy of a rotating Earth is given by K = 1/2 I w^2, where w is the angular velocity.

    The energy associated with an angular velocity which is increased by 1 second over a year is equivalent to an extra 1.6e22 Joules of energy or 40 times the annual energy consumption of mankind (DoE 1999). A detailed analysis and matlab script are available here

  10. Re:Rotational Kinetic Energy on Earth Travel On Time, Again · · Score: 1


    I didn't really have a point when I wrote that. I was just curious how much rotational kinetic energy is normally sapped from the earth due to lunar tidal forces.

    Generating energy from the Earth, as you suggest is already done in a fashion. By generating energy from the ebb and flow of the tides we are increasing the resistance to the flow of the water, thus slightly slowing down the Earth. Additionally, when a spacecraft receives a gravitational boost from a planet, the spacecraft is actually decreasing the planet's potential energy, pushing the planet into an orbit slightly closer to the sun.

    As I understand it, the majority of the lost kinetic energy is transfered to the Earth-Moon system in the form of potential energy. As the Earth's rotation slows, the moon is pushed into a higher orbit. Eventually the Earth will "tidal lock" to the moon such that our rotational period equals the moon's orbital period -- the same side of the Earth will always face the moon. (The moon has already tidal locked to us, which is why we never see the far side of the moon.)

    Sorry. I'm just having fun.

    By the way there were no books used. All that stuff is in my head! (For better or worse.)

    You have demonstrated a understanding of the topic and you do have a good point that was underscored by the new post you linked to above.

    My "Consumers Unite!" post was phrased in a manner consistent with anticapitalist protesters of the mid 1800s, who attempted to address the proletariat en masse with simple messages typically in the form of a call to action.

    This issue is classic class conflict. The corporation is attempting to maintain control over its means of production, which is in this case is a music distribution network. The primary source for maintaining control comes from the State in the form of legislation. Thus, while I agree that you have a point when you refer to public relations, this issue will ultimately be decided in the courts regardless of public opinion. Much like copyright laws, it is only a matter of time until the means of production is litigated back into the control of the music industry.

    I submit, that policing comments on Slashdot to present a good attitude serves only to create a docile community. Such a community is exactly the most vulnerable to a slow march towards legislation. We need action.

  20. Re:Consumers unite! on RIAA Settles With 12-Year-Old Downloader · · Score: 1


    I will analyze the grammar of the following post for your reading pleasure.

    Ah, but I was not speaking to logic.

    Sentence fragment. The sentence begins with a coordinating conjunction.
    Improper colloquial preposition. In colloquial speech the use of "to" as the preposition implies, that the object of the preposition is a recipient of the dialog (a person, animal, or recording device). A good substitute would be "of".

    The point is that history has proven logic alone cannot win the day.

    No errors.

    PR will first, then we hit them with logic.

    Sentence fragment. The first coordinate clause lacks a required second verb.
    Temporal disagreement. The coordinate clause is in the future tense while the subordinate clause is in the present tense, even though the coordinate clause occurs first.

    Your whole post was lacking in logic (and a point or evidence, really) and could be construed exaclty (sic) as I described.

    Faulty parallelism. The verbal element "was lacking" is incorrectly used as both an intransitive ("in logic") and transitive verb ("a point ...").

    I seek not to defend the RIAA but to make sure we portray a movement against them in the proper light to gather support.

    Improper coordinate conjunction. In sentences where the first coordinate clause is negated by the second coordinate clause the coordinating conjunction, "rather", should be substituted for "but".

    Your tone will do nothing but to turn people off.

    Unnecessary subordinate conjunction. The subordinate conjunction, "to", is unnecessary and without the coordinate conjunction, "but", risks negating the intended meaning of the sentence.

    But I'm glad you took freshman English and learned some simple logical fallacy terms! Congrats.

    Sentence fragment. The sentence begins with the coordinating conjunction, "but".
    Improper adjectival form The nounal element "simple logical fallacy terms" contains the adjectival form of "logic" ("logical") which ambiguously modifies "terms". It should be replaced with the genitive construction, "terms of logic". The use of "fallacy" is awkward and should be omitted. The revised nounal element would read "simple terms of logic".

    P.S. - This was English. The prior was Logic.

    An analysis of the logical flaws of the above reply, submitted for your reading pleasure.

    From what you just said, it doesn't matter how many people they sue, you have already made up your irrational, vindictive little mind on the issue.

    Ad hominem. The reply attacks the author instead the position through the derogatory use of "irrational" and "little".

    I (and they) guess you haven't bought a CD in 3 years nor were likely to for the forseeable (sic) future anyway.

    Speculation. There is no evidence in the post of past or future purchasing habits.

    If you actually understood the issue, you would know that:

    Ad hominem. The reply attacks the author instead of supporting the position through the implication that the author lacks understanding.

    1. The RIAA does not represent all artists. This is a problem because they pretend to. Find out which of the bands/artists you like is represented indirectly by the RIAA and stop buying those CD's. Continue to buy CD's from independent bands. I do not download music, but I have bought CD's from my favorite bands online. These are often in the $6-$10 range. If the CD has 15 tracks, thats even better than iTunes.

    Logical. This is the kernel of your argument and is well put.

    2. Your tone and phrasing does not indicate you will stop listening to new music, only that you will stop buying CD's. This casts you in the light of someone who is not about what's right, but is instead about what you can get for free. By doing this you have marginalized yourself, potentially hurting the cause. The RIAA can point to your mentality and explain to people (as I saw them do on TechTV this morning) that because of people like YOU they have to sue. Is that true? Probably not, but by spouting off like this you move yourself to the fringe and drag the rest of us with you ever so slightly.

    Speculation. There is no information in the "tone and phrasing" which conclusively conveys the complex idea of halting CDs purchases while continuing to listen to new music. The continuing train of logic builds upon the preceding speculative argument.

    Please people, if we want to do something right here, we have to come across as educated adults and not spoiled children. Though I know Mr. Foreman is not in such a position currently, please keep that in mind if you are ever in a position to represent the group. (And bear that in mind when you mod someone like this up.)

    Ad hominem. Attacking the author instead of supporting the argument, through the omission and inclusion of the author from the groups of "educated adults" and "spoiled children" respectively.
    Special pleading. The act of "coming across as educated adults and not spoiled children" to achieve the goal of "do(ing) something right" is special pleading disguised as a logical statement. It provides no support for the argument.

    My proposal? A no-CD && no-p2p week. A show of boycott AND good faith. If you stop buying CD's but keep trading songs online, you help the RIAA PR campaign. If you stop both, they can't point to p2p as your only reason for not buying CD's anymore.

    Non sequitur. It does not follow that a simultaneous boycott will eliminate p2p as a source of contention, given that p2p sharing will resume after a boycott.

    You too can detect Baloney!

  25. Equal Access on How Would You Design the Voting Technology? · · Score: 1


    Although many qualities were mentioned, the single most import quality of any voting machine was omitted. That quality is equal access. All members of a democracy must have equal access to and equal ability to use the voting machine.

    As an example, currently in California there is controversy over the decision to reduce the number of voting booths in Los Angeles County from the normal 4922 voting booths to 1800 booths for the recall election. Because of the increase in the commute time required to reach a voting booth, portions of the population may find it difficult to vote.

    At the risk of drifting off topic, equal access should apply to the basic education required of all citizens as well. To have a true democracy, a society must provide in basic education the tools for any citizen to become a politician. Thus the argument that Gray Davis is uniquely qualified for the role of Governor would be moot. All citizens should be provided with an education that would allow them to hold a political office.
