    Most of those problems are "last mile" issues which vary greatly depending on the endpoints. For many applications (trucking, commuting) the route is known in advance. Driving off road in the desert has a slew of hard problems as well (vibration, dust, random obstacles etc), which we now know are basically solved. The army has mandated that 1/3rd of their fleet will be autonomous within 10 years. Undoubtedly that will entail a couple orders of magnitude more effort but they have the money and the will to do it.

    Driving on normal roads is vastly easier than navigating the grand challenge terrain. In fact there have already been cross-country drives of autonomous vehicles on public roads.

    We already have traction control, adaptive cruise control, automated parking and drive-by-wire on the consumer market. The only thing that is not automated is steering and braking. Pre-emptive braking and obstacle-avoidance technology is very close and will probably begin to emerge on the market within a few years (motivated by safety concerns). Automated steering at up to freeway speeds will only be a few more years behind. At first it will be a switchable system with manual override like cruise control is now, so there will be nothing for the anti-technologist to scream about (people already have accidents when cruise control systems are engaged and it does not cause an uproar), and given another decade or so when people have really gotten comfortable with the technology, vehicles without drivers at all.

    hypocritical: professing feelings or virtues one does not have.

    Environmentalists drive cars. Overworked doctors cannot spend sufficient time to address the needs of every patient. In "democratic america", judges are appointed to the highest courts with life-long terms. BM needs money, rules and legal services to survive. And yet, these entities still posess some aspect of the virtue they profess, and in no small quantity. As long as they guide their actions with pragmatism and stay true, to the extent that is realistic, to their principles, it is not hypocracy.

    To call it hypocracy is extremism. Its a psychologically comfortable place to be because its a logically defensible position -- but strictly logical arguments are almost never applicable in the real world, which is filled with conflict in almost every system. We can pick facts and take quotes out of context all day without breaking the rules of logic... but that does not mean the conclusions are sound.

    Political parties constantly exploit this effect to their advantage -- and the media does it also, because extremism is exciting. So its no suprise that the mentality has become so pervasive in mainstream consciousness. I think its unfortunate because this cynicism seems to cause a great deal more suffering than is necessary.

    Sometimes I feel like people need to criticize BM so they can come up with an excuse to not go. Its like turning down an invitation to a party, you don't want to look like a dork for doing it so you come up with some stupid reason. I say its not for everyone, just accept that (there are certainly things that I would rather do, it depends on my mood). BM strives to create an "experience" for one week, but that is really where it ends. Unlike Disney, BM is not trying to take over the world.

    Mr. Zawinski is does not make factual errors, therefore there is nothing to disagree with on a technical basis -- hovever his analysis is generally uninformed, one-sided and dogmatic suggesting that he does in fact, have no clue (or maybe he does but wants to generate a controversy for the sake of publicity).

    His one and only critique is that Burning Man LLC is "hypocritical" because the restrict the actions of the media in their space while claiming to be "free spirited, anarchic, spontaneous, community creation" etc.

    Why is this total BS? Quite simply, BM does not make any such claim. Every legal standard that applies in the "real world" also applies at BM, except public nudity, intoxication and pyrotechnics. There are cops. Drugs are still illegal and you can be arrested. BM lays out a whole slew of other rules -- they regulate noise, pollution, use of motor vehicles, activities of media and other professionals, they hold and enforce trademarks, employ lawyers. If they didn't do this, the event would be a catastrophe. It would be discontinued. If you spend any time at all reading their official literature and communications you would notice that they spend a significant portion of it re-iterating the rules because they are the glue that holds it all together. Zawinski has clearly never actually spent time reading this material as his analysis gives only anectodal quotes taken out of context with no reference and quotes from unofficial sources (e.g. media articles).

    If BM asks for a cut of the proceeds, does that mean they are automatically going to sell unlimited rights to the highest bidder? NO. They allow what they think is appropriate. If BM files a lawsuit to stop distribution of Voyer Video's material, does that mean they are just after the money? NO. They are seeking control, not money. Therein is the logical disconnect -- there is no hypocracy.

    Zawinski's interpretation is totally polarized, and wholly unrealistic. He is living in a fantasy.

    You sir have no idea what you are talking about.

    Burning Man is NOT anarchy and has never claimed to be. Its not a free market, quite the contrary. Rules exist for a damned good reason, and this one in particular is supported by an overwhelming majority of participants. Until people think its "cool" for Fox News to broadcast live coverage from the Playa, until people think its "cool" for 2-bit pornographers to shoot footage of naked people for profit, that rule is not going to change. People go to Burning Man to have fun, not to be the animals in a media circus.

    Yes, Burning Man is a (non-profit) corporation. They annually raise and spend millions of dollars on the event. They deal with nasty legal problems and miles of beurocratic tape to make it happen. Comparing them to Disney is totally absurd.

    Check the specs on the drive to see if the drive is rated for 100% duty cycle or not. If not then to maximize drive lifespan the drive should be powered down (or sleeping) for about 50% of the time (usually when you are sleeping, too). If you use one of these drives in a 100% uptime environment (e.g. web or e-mail server) it will usually fail prematurely (within about 2 years in my experience). The engineering of the motors, actuators and bearings simply cannot withstand abuse (probably a combination of insufficient heat management and less precise tolerances in the manufacturing of parts and/or cheaper technology).

    also; most other forms of art can be explained in roughly the same terms, with some variation on the definiton of #1 (e.g., two dimensional spatial organization of matter == painting). due to the enormous amount of effort it takes to master pts 2 and 3 within a given mode of expression (pt 1), it is necessary for artists to specialize in a fairly narrow set of forms.

    scientific domains, engineering (production of goods/services etc), advertising, politics, programming etc are distinct from art forms in that their product in terms of cognitive availability/influence (or physical availability/function) is constrained to fit within a certain form -- respectively, information derived from repeatable initial conditions, a fintely defined product or service that meets a requirement, stimulation of a compulsion to participate in the economy, influence on morals, functionality etc. some forms fall into multiple categories (e.g. industrial design, mainstream pop music, political art, perl poetry, etc...). the reason art is interesting is that it is underconstrained -- it resonates with or stimulates consciousness (i.e., roughly, free will).

    music is:

    1. characterized by temporal arrangement of energy (organized vibration of matter in various states).

    2. cognitivly availble and influential to the listener (though strictly speaking the listening does not necessarily happen through the ears -- vibration is perceptible through various senses such as touch as well)

    3. created by the composer/performer using an intentional process -- and the intentional process must be guided by knowledge of its effects on #2 -- this is why playing scales, random environmental sounds, and a stereo playing with no-one listening are not music, why it is *possible* to have music generated by a computational process, and why badly practised performers (and wolframtones) create bad music (because they lack intentional control and/or lack the understanding of their actions on cognitive availability/influence wrt. the audience)).

    Cage understood music as such and challenged the prevailing assumptions (e.g. "music is X, X a member of the set {string quartet, jazz trio, etc}") in order to reveal the core definition -- and he did it by force -- by pushing music right out to the extreme limits of the definition (which made many people uncomfortable (I have a historic live recording of a Cage piece where after it is finished, half of the audience is wildly cheering and the other half is booing).

    On pt. #1 -- that the organization of energy could include the total lack of energy (e.g. four and a half minutes of silence), which regardless still has a profound effect on the listener. That temporal arrangements could include intentional disarrangements (by the influence of chance to create non-repeatable performances).

    On pts #2 and #3 -- that the degree of cognitive availability could include intentionally steering the music to be totally unavailable (another byproduct of using randomness as a source for composition).

    The mind seems to have an automatic system for fuzzy categorization of phenomena, which produces incomplete paraconsistent semantics. As long as the definition of a concept/phenomenal-set remains incomplete there is a proliferation of philosophically useless question-begging and circular reasoning (i.e. "don't be a fuckwit", as you put it). However many such things are eventually resolved in the light of new information (e.g., the recent advances in the theory of consciousness). Cage was truely a pioneer in this sense by presenting some rather startling new information. That said I don't particuarly enjoy listening to much of his music, but that is mostly a matter of personal taste.

    David Cope at UCSC (and perhaps others) has been a major innovator in this area for years. His programs can analyze scores and learn to compose music in the style of various composers. He has a book about this called "Virtual Music" and a slew of other publications.

    The idea of algorithmic composition has been around for a long time. There are a lot of interesting aspects; use of statistical modelling (markov processes, machine learning, etc), computational models of music cognition (Temperly, Lerhdal and Jackendorf et al).

    Since NKS there have been a number of attempts to use CA processes for musical generation (e.g., multiple papers at ICMC 2004 on this). None of it thus far has been terribly convincing (IMHO). As various people have pointed out, these sorts of attempts to use various arcane mathematical/computational models as the basis for music generation introduce a vocabulary to music which is fundamentally non-musical -- its not grounded in any perceptual theory, there is no evidence to support that it has any meaning with respect to a human listener.
