  1. Re:I've got a better idea on 1000-mph Car Planned · · Score: 5, Insightful

    Some simple calculations will show you that 1000 mpg (for g as in gallon of gasoline) is physically impossible.

    (1) Energy content of gasoline --- 36.6 kWh/US gallon. Let's assume that your engine works at the absolute thermodynamic limit (40%) for a combustion engine so you get 16 KWH of work out of it.
    (2) The power to move your vehicle through air is P = (1/2)(density)(projected area)(drag coeff)(velocity^3)
    (4) At sea level, 25C, 60 MPH, A = (1 m)^2, CD = .1, you have to expend P = 1.25 KW to continue moving.
    (5) In one hour, therefore, you have consumed 1.25 KWH ~ (1/12) gal. You have also moved 60 miles, giving you 60*12= 720 mpg.

    So, even under the most generous conditions, you cannot possibly do better that 700 mpg. Of course, we have neglected rolling friction of the tires and assumed that your regenerative braking system is so good that you expend no net energy starting and stopping. 720 mpg is just the energy required to move the air out of your way as you cruise to work.

    At first, I was going to mod you OT and move on, but I felt like there was something important to be said here -- efficiency is not like performance. In performance, one can always throw more energy at the problem (he's using a jet engine FFS, new sports cars are always breaking HP limits) but when going for efficiency, you are going to see diminishing returns. 100 mpg is doable, 200 mpg is doable with severe sacrifices (mainly in the comfort/cargo dept). Past that, I feel like the laws of physics are not going to be particularly kind.

    WARNING, EXTENDED (hopefully thoughtful) CAR ANALOGY FOLLOWS

    Volume of source code is not a good measure of relative importance any more than a fuel tank is the most important part of a car because it's the heaviest. Nor is ease of replacement probative -- I can replace the timing belt on my car in 20 minutes (faster than changing oil), yet I would still it as a critical component. Nor is the hypothetical functionality with the component removed a good measure -- remove the battery and my car won't go anywhere at all, yet it is still a peripheral part.

    The only way (AFAICT) to analyze the relative positions of components of a complex system is by the degree to which they interact with other parts -- the degree of 'connectedness' they are in the network. The timing belt is significant because it interfaces the crankshaft (output power) with the valves and fuel injection system (input power). It's right at the center of things, talking with all the major players. The battery, on the other hand, is isolated from the system save for a single connection, one that provides only bulk voltage. It does not talk to anyone (unless it's dying :-), nor does it receive any information. In other words, it's just not an interesting.

    Turning to GNU/Linux, it's clear that they are both equally important on network-theoretic terms. The kernel sits right smack at the center of everything, talking and listening to everyone and sticking its thumb in every pie. glibc, BASH, X, etc . . are likewise important, mediating between the user and the kernel, talking to the applications, linking libraries and likewise, have their thumbs in all the pies. If you drew a graph (in the mathematical sense) of the GNU/Linux system together, the two would very heavily connected at the center while everything else went around them.

    Elevating one above the other is utter nonsense.

    Let's revisit the GP for a second:

    Let's say, I, as a developer write some software and give it to you, but just the binary. Let's say I let that you use, copy, and modify that software as you wish. In other words, you have natural freedoms to do as you please. Now RMS comes along as says "That's not freedom! you didn't give him the source!"

    What I contend RMS should have said is "That's not freedom, the way I see it" or, "I think your definition of freedom is too narrow" or something that recognizes the particular subjectivity of his definition. The term "Free Software" is just too general a phrase to be subject to arbitrary redefinition.

    You are correct, of course, that in the context of the FSF or GPL, "Free software" acquires a different meaning, but that's only within that context. Assuming that every time someone on the internet talks about "free software" (and doesn't explicitly link it to the particular FSF conception of freedom) they intend to invoke that context is presumptuous (although the speaker should probably be more clear).

    I wasn't aware that the FSF had the right to redefine phrases in natural English. They certainly have a definition of free software but I see no reason that the GP needs to adopt that definition as his own. RMS is not the ultimate authority on the meaning of words in the English language.

    As a general supporter of the FSF's goals (in a practicality-oriented sort of way), I have always been philosophically disturbed by their claim to attach a technical definition to an ordinary phrase. If they wanted to introduce a novel concept, the four freedoms, they should do so in an intellectually honest way that does not lay claim to ordinary adjectives. The easiest way would be to invent a word -- "freefour" or "fourfree" (I'm not a marketing droid, that's the best I can come up with).
