    Religions, reward after death religions, have to be like this. Else you get mass suicides.

    I think it's mostly the other way around. People have survival instinct. Therefore they need to rationalize why they must keep on living, even if death would lead to a paradise of some sort. And this survival instinct reflects on religions.

    But you're right otherwise of course, with clarification of any religion that lasts any significant amount of time has to be like that. A religion can certainly endorse mass suicide, it just won't last very long then.

How to achieve that, and what things should be taken care of together, now that's debatable, but the basic premise of your statement, that things should be taken care of only voluntarily, and "freeloading" should be allowed, or it's "... not so good", that's fundamentally broken (human nature and all that).

        Most of the world shifted from being hunter-gatherers (with some exceptions) to agrarian systems an awful long time ago. For most civilized countries, hunting became a sport, not a means of survival. For the most part, we survive on domesticated animals and farm raised plants, which are purchased in local stores. There are exceptions, but those are few and far between, and even then, you probably wouldn't be posting to Slashdot if you were there.

        Don't try to fool yourself, only a very small percentage of those living in modern society could live without our modern infrastructure. Ask your average city dweller to catch a pigeon.

    If that average city dweller could gain a lot (relative to his situation, for example $50 per bird or something in New York) by catching pigeons, you'd see pigeon population plummet, hunted by those very city dwellers. It'd be matter of weeks before those city dwellers would be very proficient pigeon hunters (provided the pigeons would not run out before then).

    Not to mention, this was about India. With what... 800 million poor, many of who would gladly hunt owls if they got any money from it. Now let's say only 1% of them have potential to be good hunters, which leaves us with only 8 million good owl hunters. Still not very many owls per hunter...

    C doesn't care at all about indentation. You can remove all the lefthand space from a C program without affecting it in any way. Pythons meaningful whitespace is a terrible idea, absolutely horrific really.

    Well, C cares about indentation in the way, that indentation has to be spaces or tabs, if there's any. Worst of all worlds, which is discovered by anybody who has worked with mixed up tab-space settings in files in version control. Worst case is having different amount of space per tab been used in different parts of the code, and tabs not used consistently. Result is, no matter how you configure the editor, some part of the code gets indented unevenly, and you can't fix it without messing up version control diffs.

  9. Re:Python is the Lisp of the 21st century on Land of Lisp · · Score: 2, Informative

    Python does precisely that. It mixes presentation (what code looks like) with content (what code does).

    To some extent, every language does that. What I meant is that the TAB character introduces an arbitrary visual configuration that's not part of the language itself, which can confuse things when tabs and spaces are mixed in the same source file.

    I think better solution to not having tabs would have been if C would only have accepted tabs as indentation. And if python had "one tab is one level of nesting", I think that'd have been better too.

    Problems only arise when mixing tabs and spaces, and when not agreeing how many spaces indentation is, or how many spaces tab is. I'm sure most of us have encountered source files which have had all three of these, after being edited with many people with different editors and settings. "One TAB equals one level of indentation" would fix all that. Any programmer could use any amount of spaces for displaying tabs in editor, and it would not affect the source file.

    However, this does not mean that the presentation of the code is unimportant. For instance, a reason why I once programmed in Pascal but switched to C was that I found braces easier to read than "begin ... end" pairs. Curly braces are clean and small symbols, looking at the source code at a glance they are easier to identify than multi-character keywords.

    When you are writing and reading code by the hundreds of thousands of lines, every detail becomes significant. That's something language theorists often fail to understand, but Dennis Ritchie and Guido van Rossum got perfectly right.

    Indeed. However, these days code presentation, including automatic indentation, is largely taken care of by the editor (and if it isn't, maybe it's time to either learn to configure it, or switch to a more capable one). Except this is rather hard for Python, for the obvious reason. IMHO this is a serious and unique shortcoming of Python.

    Don't they? Explain visual feedback programming differences between running python on today's macs with running basic on, say, the Apple II of old.

    screen 7:for x=0 to 320:color x/4 mod 15+1:line (x,0)-(320-x,200):next

  11. Re:computers come with accessible languages on Land of Lisp · · Score: 1

    The premise that modern computers don't provide a language as accessible as BASIC seems questionable.

    Modern languages don't have IO interface comparable to decent line-number BASIC. I'm talking about commands and functions like these in gwbasic: screen, locate, print, p(re)set, line, input, inkey$, sound, timer.

    And no complex concepts like functions (introducing identifier scopes and things like that).

    And goto! Let's not forget goto, the ultimate tool for adjusting the complexity of the program approximately by a factor of (number of gotos/10)^10, as compared to an equal structured program.

    That translates to really trivial simple demo programs and games. No setup needed, no worrying about screen resolutions or character encodings or locales or libraries or... anything.

  12. Re:Python is the Lisp of the 21st century on Land of Lisp · · Score: 4, Insightful

    What Lisp promised then is what Python promises now. With one difference, in that Python respects the visual limitations of humans.

    Different from parentheses, it's very easy to undo a bunch of indentations, just put the left margin where you want it.

    Well, if only the TAB character had never been invented... TAB is a kludge to make a typewriter behave sort of like a spreadsheet but, unfortunately, it fucks up the excellent "Don't mix content with presentation" principle.

    Saying "Don't mix content with presentation" is pretty rich from a Python advocate, when Python does precisely that. It mixes presentation (what code looks like) with content (what code does).

    Besides, don't you know that in Lisp, parentheses are indentation symbols? They tell how the code should be indented, and changing indentation is just a matter of changing parentheses. If anything, adjusting indentation of Lisp code is easier than adjusting indentation of Python code.

    If I'm understanding this right, the deal is that ion engines don't put out much thrust, but use less fuel (and more energy) doing so. So theoretically, if you could cram a large enough fuel supply into the vessel, you could, using constant acceleration until the fuel supply was exhausted, accelerate to a higher speed? Maybe mcg meant that you could accelerate for a longer period?

    More fuel = more mass = lower acceleration with same thrust.
    Adding bigger engine (spending more fuel) = More fuel = see above.

    When you work the maths out, it boils down to a single number called "specific impulse or I_sp.

    Ion engines only put out little thrust, because we don't know how to make an ion engine that could put out more thrust, which means using up same amount of energy takes longer time. It's not any kind of advantage, it'd be better if we could use the energy faster (reach top speed faster).
