  2. What is beauty? on Is Computer-Created Art, Art? · · Score: 2, Interesting
    Asking, "What is art", is really asking the question of intelligent design. In other words, is an object an "artifact" - directly or indirectly caused by an intelligence such as a human being, or is it the mechanical outworking of the laws of physics? If something is "artificial", it is designed rather than natural - although the word has taken on negative connotations in recent centuries.

    Sometimes it can be hard to tell the difference. At the Smithsonian museum of natural history, there is a large rock intricately carved by water channels that could just as easily be displayed at the Hirshorn. Nevertheless, this is a question that can be objectively answered (in the case of the rock, it was not designed), and is answered every day as courts consider whether a death is really accidental and archaeologists consider whether a flat pointy rock is really an arrowhead.

    Of course, if you are a philosophical naturalist, you believe that this universe is all there is, and every event is purely the outworking of the laws of physics. In you take that position, then nothing is art, and there is no true intelligence - just the appearance of it. For the word "intelligence" means to choose between - which can't happen when every action is determined by physical law (whether deterministic or stochastic).

    While recognizing intelligent design is difficult for many, an even more difficult problem is recognizing beauty. After all, art can portray both beauty and ugliness: Tolkiens epic involves both Elves and Orcs. But is beauty subjective, as Voltaire proclaimed? Or is true beauty an objective reality, and differences in its perception due to variations in the loss of our faculties for perceiving it?

    In case it isn't clear, based on my definitions, the typogenerator is obviously artificial, and hence it is objectively art. Perhaps what people are really unsure about is whether the pictures it generates are beautiful, ugly, or just random? I would give my opinion, but the site has been slashdotted.

  4. Forks are like branch prediction. on Flame Wars, Forks and Freedom · · Score: 2, Insightful
    High performance processors read ahead in the instruction stream, so that multiple instructions can be processed simultaneously. When such a processor encounters a branch, and the branch condition is not yet known, what does it do?

    Some designs guess which way the branch will go, and continue accordingly. When the branch condition becomes known, and it guessed wrong, it throws away all the work on that branch and starts over causing a pipeline stall. Often, extra bits are available in the branch instruction to provide hints on which branch decision is more likely. The processor may even keep stats on hot branches in a branch prediction cache.

    Other designs work on both forks of a branch simultaneously. When the branch condition becomes known, the execution tree is pruned. A fork in an open source project effectively pursues both branches simultaneously. One difference is that while often one branch is discarded (e.g. what will probably happen with the XFree86 fork), but sometimes both become viable options (e.g. Gnome and KDE).

    The first kind sincerely believe that certain behaviours are good or bad, but personally find it extremely difficult to muster the willpower to live up to their own standard - and frequently fail. An example would be the doctor who is a chain smoker - but takes care not to smoke in the examining room, and can show you no end of pictures and statistics proving just how bad smoking is for your health.

    The second kind of hypocrite does not actually believe his own propaganda, but merely uses it to manipulate others to his advantage. An example would be the Communist Party bosses in the old Sovient Union who would preach austerity and economic independence from the West by day, but buy Western luxuries in secret Party shops by night.

    The Christian Church has always been full of the first type of hypocrite - and openly so. "I am come not to call the righteous, but sinners to repentance," said Jesus, and a modern bumper sticker says, "Please be patient, God is not finished with me yet."

    Just as you should pay attention to the doctors advice about the dangers of smoking - even though the doctor fails miserably at taking his own advice, so you should take seriously warnings about the dangers of pornography - even if the preacher fails to take his own advice.

    Perhaps you suspect that TV preachers are the second kind of hypocrite - not actually believing what they preach, but cynically manipulating their audience to keep sending in those donations. For the majority of TV preachers, I would agree with you. Even then, however, to the extent that they accurately portray the message they claim to represent, you should take the message seriously. As Paul said, "The one preach Christ of contention, not sincerely ... What then? not withstanding, ..., whether in pretence or in truth, Christ is preached; and I therein do rejoice."

    Unfortunately, while scientific measurements may be getting more accurate, the accuracy of mass media preachers resembles the accuracy of marketroids at a tech company. They tend to modify their message to tickle the ears of the target audience. To see what a given Church teaches, take a Church document with some history behind it, ignoring recent "innovations", and then compare it with the sources (the Bible and history).

  7. Nudity is not porn on Is Atlas Holding Hipparchus' Lost Star Map? · · Score: 3, Interesting
    Porn is a difficult thing to define objectively. On the subject of defining pornography, an American Supreme Court justice said in frustration, "I know it when I see it, but I can't define it."

    The basis of Christian (Catholic and Protestant) ethics concerning sexual behaviour is the concept of "defrauding". In this context, to defraud someone is to arouse desires that cannot be righteously (or practically, for you libertines) fulfilled. Pornography is the ultimate in sexual defrauding, hence it condemned. Solomon puts it more positively, "I adjour you, awake not my love till it pleases." In other words, don't arouse me until the time is right and we can enjoy it to the utmost. (We don't need to be reminded of how Solomon did not exactly set a good example of sexual restraint. He regretted it afterward.)

    However, the precise stimuli which result in inappropriate arousal is very culturally relative. A Christian family I know was visited by a Christian family from Russia. They met them at the airport, and the American wife gave all of their visitors a big hug. Later, they discovered that this made the Russians very uncomfortable. (This may reflect a particular subculture in Russia, and not Russians in general.)

    My sister spent some years in the jungle in Papua New Gunea. The Christian women there were very few clothes, often going topless due to the climate. This did not seem to provoke the wrong response in the men. (Although I've heard that it does for American boys reading National Geographic.) Strangely, the Papua women were shocked by magazine photos of American women in bikinis. Objectively, the bikinis represented more cloth than what the Papua women wore, but there was something about the facial expression and body language that said "come hither", and thus became pornography.

    One more thing, Eros is exclusive and jealous by nature. Promiscuous behaviour does not contradict this. When that special someone says to us, "I love you!", we are thrilled. When we discover that they are saying the same thing to 10 other people, we are not so thrilled. Some people have expressed the idea that pornography might be appropriate within marriage (or whatever you libertines want to use as a substitute). However, because an image rather than the beloved becomes the source of arousal, it diminishes Eros and cheats both partners.

    Games that are highly realistic, like high end flight simulators, can actually train reflexes and unconsious strategies that are effective in real life.

    "Refrigerators" in this context is a measure of volume. BLOC is a measure of energy. There is no obvious conversion from energy to a volume unit. e =mc2 doesn't help without specifying a density.

    A typical refrigerator is about 60x30x36 cubic inches. The transportation industry is interested in the volume, and in the largest dimension (or the largest dimension of a rectangular box that can contain the object). Assuming the refrigerators are strapped together on their smallest dimension, the resulting machine would be 60x90x36 inches, for a total volume of about 112.5 cubic ft and largest length of 7.5 ft.

  18. Preventing DOS, not security, is the target on Quest For "Unbreakable Java" Unites ABAP & Java · · Score: 3, Informative
    The Java VM is already very secure from a code exploit standpoint. The machine model provides an unescapable environment which is equivalent to the hardware "user mode". It is straightforward to extend the API in pure Java to provide logically isolated "processes" and/or users, and many previous projects have done so, for example JDistro. All in all, Java provides excellent protectation against attackers executing arbitrary code and buggy programs corrupting memory.

    However, the standard Java VM does not provide any way for a supervisory process to limit two key resources: memory and CPU. The Thread.stop() call is useless against a malicious DOS attack via Threads with infinite loops since the attacker can simply provide a "finally" clause that perpetuates the loop. Thread.stop() is even deprecated in later version of Java. Furthermore, there is no way to limit the memory that malicious code can allocate via new (unless I missed something in recent versions). So crashing a JVM via malicious applets or servlets is trivial. This is acceptable for a web browser (just restart the JVM), but not so good for server side Java. Furthermore, infinite loops and data cancer (actual memory leaks where the memory is allocated but not referenced anywhere are impossible in pure Java) are common failure modes of honest but buggy software, so JVMs too often crash due to either CPU or memory starvation even when only trusted code is running.

    The goal of the system described is to provide a way to limit CPU and Memory consumption by leveraging the process model provided by the OS. Furthermore, the hardware enforced user mode helps protect against JVM and JNI bugs that might otherwise break the Java machine model (and allow memory leaks/corruption or malicious native code execution). Having multiple layers of protection is always good.

    I never understood the problem. Since I started in software in 1972, we've stored dates as 32 bit julian day numbers. A library routine converts to/from human readable format (including lots of those quirky shortcuts humans enjoy)- only slightly more complex than converting other binary numbers to decimal with fancy punctuation. For dealing with business logic like "first monday in november", there is another conversion to/from a month,day,year triple. Y2K was a non-issue.

    When we went to unix, timestamps were already simple integers - easily convertable to/from human notation and to/from a tuple. With proper timezones, leap seconds and historical changes are all accounted for in the conversion.

    Java extends the timestamp size to 64bits - avoiding the Y2.038K crash. The Java system is easily extended with a fully implemented Timezone class (leap seconds, historical changes, etc), but the standard GregorianCalendar text conversion routines don't provide a name for leap seconds (e.g. 02:59:60 am) and use only two timezone abbreviations (a problem with historical changes like EDT,EST,EWT).

    One thing the Java system does right is convert timestamps to an arbitrary length tuple. The tuple length depends on the Calendar implementation. As a result, it works perfectly well for specialty calendars like Mayan - as well as commonly used calendars like Hebrew, Arabic, and Gregorian.

    If your goal is making sense of this universe, then science is the way to go. The information in the Bible is valuable because it addresses things not discernable via the scientific method. (Although it often mentions things in passing that can be checked historically, for example skeptics have pointed to a great many cities mentioned in the Bible that they claimed were made up - but archeologists eventually uncovered them.)

    I think we may be in agreement that making the Bible a science textbook is a foolish endeavor.

    Tokein's The Lord of the Rings is incredibly detailed. And yet, it is clearly not intended as literal history. Homers Illiad is a mythic retelling of what was probably a historical battle that took place long enough ago to grow in the telling. I suspect it has both true and make believe parts, just like our own mythic retellings of the founding of America. (I should point out that we also have the original documents for most of the important events in American history, and we have the original autographa for most of the writings of our founding fathers. So much of the historical revisionism that is popular today only fools the ignorant.)

    When I read Herodatus, I am reminded of the National Enquirer. He clearly intends to be factual, but gives priority to the sensational. However, many of his matter of fact descriptions I think are wrongly dismissed. For instance, when he describes the frankincense harvest in Egypt, he says that the workers had to first use smoke to drive away the flying reptiles. While we can sit in our armchairs and speculate about what he really meant, I think there really were flying reptiles. He is not the only ancient writer to mention them.

    The point is that you need to treat each work of literature as the style that was intended. While some parts of the Bible are written in mythic language, Joshua, Judges, Samuel, Kings, Chronicles, are all dry history. The Gospels are compilations of first and second hand eyewitness testimony.

You assume that our universe has an objective existence that does not change just because your beliefs or perceptions change. This hard objective existence is the Autographa of the scientific method. It is the ultimate authority on how this universe works.

    However, you can't actually see or know this Autographa directly. You are dependent on fallible senses which are subject to illusion and distortion and the health of your body.

    Your summary is basically correct. But your conclusion doesn't quite follow. Christianity asserts the "perspecuity of Scripture". This means that despite the lack of ideal mathematical perfection in the transmission, translation, perception, and understanding of Scripture, it is nevertheless clear and understandable. Your writing skills and mine are far from perfect, yet we understand each other. In the case of Scripture, God himself has engineered it so that the message is understood well enough for us to come back to Him. If we want to: as Jesus said many times, "He that has ears to hear, let him hear." If you are determined to misunderstand the Bible, or another human being, you will succeed.

    You've just argued a case that can be used to destroy *any* argument based on Scripture.

    Semantic holism is the idea that the meaning of words is determined by the unique context and life experiences of the speaker, and they mean something different to another person. For instance, when Clinton made his famous defence, "It depends on what the meaning of 'is' is," he was referring to the concept of Semantic holism. He wasn't lying if you only understood his words in the way he meant them at the time.

    Taken to extremes, semantic holism can be used to destroy any argument based on anything, not just Scripture. However, such arguments are no more convincing to non-eggheads than that line of Clinton's defense. Common sense tells us that despite the imperfection of human language, we *do* manage to communicate with each other. We can usually tell when a misunderstanding is unintentional, or a deliberate attempt to deceive or provide "plausible deniability".

    Scripture is God's message conveyed in human language. It needs to be understood in the same way that you would understand any other person of another culture. Arguments based on extreme literalism deserve to be destroyed. For instance, a certain radio preacher told a story of how he was hiking and his feet were cold. Then he remembered the passage from Psalm 119 that says "Thy word is a lamp unto my feet, and a light unto my path." Also remembering that in bible times lamps used flames, he took out his Bible and held it near his feet to warm them up. Now if you had written a song on a subject very dear to you, and someone abused the lyrics like that, you would either be very offended or rolling on the floor laughing.

    Unfortunately, Scripture is too often quoted in just such an abusive way, in the hopes that it will magically provide authority for an argument. Scripture is not the only authority to be abused. For example, a certain feminist wrote that Thomas Aquinas said women were of an inferiour nature in his Summa Theologica. Thomas wrote each article in Summa Theologica in three parts. Part I states an opposing viewpoint in the best possible light. Part II quotes Church authorities opposing Part I. Part III is Thomas' own arguments against Part I. The feminist quoted Part I of an article dealing with the Aristotelean claim that women are in fact inferior to men.

    In most cases, the literary style of Bible literature is clear. The Psalms are poetry (that rhymes ideas rather than sounds - fascinating), and when the Psalmist says God "covers us with his wings", it doesn't mean God is a giant chicken. On the other hand, in a historical journal like Joshua that goes into such minutiae as troop counts, you have to take the journal entry recording that the sun stood still in the sky for about 24 hours quite literally.

    The beginning of Genesis is told in mythic language. This does *not* mean that it is not historically true. For instance, we have stories told in mythic language of the founding of America.
