  1. Critical Mass (less cowardly version) on Rob Levin, lilo of FreeNode, Passes · · Score: 2, Informative

    Many of us only knew Rob from his "global announcements" on IRC, but still he will be sorely missed. I only hope his death does not discourage cyclists. The more people cycling, the safer it is for cyclists everywhere, and the fewer sad incidents like this one.

    I will be supporting lilo and cyclists everywhere by attending Critical Mass [wikipedia.org] to make it safer for cyclists. I encourage all slashdotters and freenoders to seek out and attend their own local Critical Mass (organised by YOU).

    The next Critical Mass is Friday 29th September near you. Google it. Support cyclists.

  5. Not completely on Australian Science Makes the Regenerating Mouse · · Score: 5, Interesting

    It just says that other pressures have been greater than the pressure to (keep the ability to) regenerate. Or the costs of being able to regenerate are probably prohibitive.

    The competing pressures might include (for example) a pressure to be smart or strong enough not to lose body parts in the first place, or a pressure to develop coping strategies when a limb is lost. Or the pressure to give food and resources to offspring, over attempting immortality. Or the pressure to have more complex tissues (even if they are more difficult to regenerate), although the article sheds a shadow of doubt on this last one. If these competing pressures are great enough, and more importantly, the pressure to keep the regeneration trait is low enough, the trait will simply drift away (randomly mutate) into nonfunctional genetic code. It doesn't mean it is completely undesirable.

    More "complex" animals like humans don't lose a lot of body parts on a day to day basis. And those who do, have their (evolutionary) fitness determined by their ability to cope with the loss, rather than by their ability to regain those parts.

    2. Kozmo.com

    Kozmo.com was a venture-capital driven online company that promised free one-hour delivery of anything from DVDs to Starbucks coffee. It was founded by young investment bankers, Joseph Park and Yong Kang in March 1998 in New York City. The company is often referred to as an example of the dot-com excess.

    Kozmo promoted an incredible business model; it promised to deliver small goods free of charge. The company raised about $280 million including $60 million from Amazon.com. The business model was heavily criticized by business analysts, who pointed out that one-hour point-to-point delivery of small objects is extremely expensive and there was no way Kozmo could make a profit as long as it refused to charge delivery fees. Not surprisingly, the company failed soon after the collapse of the dot-com bubble, laying off its staff of 1,100 employees and shutting down in April 2001.

    3. Napster

    Napster is an online music service which was originally a file sharing service created by Shawn Fanning. Napster was the first widely-used peer-to-peer music sharing service, and it made a major impact on how people, especially university students, used the Internet. Its technology allowed music fans to easily share MP3 format song files with each other, thus leading to the music industry's accusations of massive copyright violations. Although the original service was shut down by court order, it paved the way for decentralized P2P file-sharing programs, which have been much harder to control. The service was named Napster after Fanning's nickname.

    4. The Concorde

    The Aérospatiale-BAC Concorde supersonic transport (SST) was one of only two models of supersonic passenger airliners to have seen commercial service. Concorde had a cruise speed of Mach 2.04 and a cruise altitude of 60,000 feet (17,700 metres) with a delta wing configuration and an evolution of the afterburner-equipped engines originally developed for the Avro Vulcan strategic bomber. It is the first civil airliner to be equipped with an analogue fly-by-wire flight control system. Commercial flights, operated by British Airways and Air France, began on 21 January 1976 and ended on 24 October 2003, with the last "retirement" flight on 26 November that year.

    5. GM's EV1

    The EV1 was the first electric car produced by General Motors in the United States. The experimental cars were the only vehicles in the history of the company to bear the "General Motors" badge. GM leased about 800 EV1 cars with the proviso that after the three-year leases were up, the cars reverted to the company. They were only available in California and Arizona and could only be serviced at designated Saturn dealers. The first generation EV1s used lead-acid battery batteries in 1996 (as model year 1997) and a second generation batch with nickel metal hydride batteries in 1999. As cars came off lease, they were refurbished and upgraded to second generation. GM spent more than $1 billion developing and marketing the EV1, but the company decided that it could not sell the car in enough quantities to make the EV1 profitable. The program was stopped in 2003.

    1) Haven't we been around for more than 100,000 years?

    Humans, in their current anatomical form, have been around about 100,000 years. I meant it would take "another" 100,000 years.

    I have to admit the 100,000 year figure for becoming a new species was plucked from the air, and on second thought is a very low estimate.

    Homo erectus lived 2 MYA and Homo habilis 2.4 MYA. So maybe 500,000 to 2 million years would be a better guess. That time frame implies evolutionary pressure to speciate or seperation of human groups for all that time, which seems very unlikely what with transport what it is today and (to go back to the thread) institutionalised racist segregration being unsuccessful, to say the least, at forming seperate gene pools even for a short amount of time.

    2) sorry. my maths is bad, and the post was hurried (slow posts seem to be ignored on slashdot). i probably meant 2.5k generations, which isn't very much at all in evolutionary terms, so i'd rather change the years to 1 million instead and keep 25k generations :)

  10. because humans select for it. on Butterfly Unlocks Evolution Secret · · Score: 1

    They have markings because humans like them to look like that, so we select for animals with markings.

    For example, dalmations are often deaf because the same gene for a white coat leads to deafness, but we (humans) keep breeding dalmations anyway. Why? Go ask a human. It's humans doing it.

    From an evolutionary perspective: domestic animals with attractive (to humans) markings are better adapted to being allowed to breed by their human overlords, whereas less interesting looking domesticated animals are less adapted to pleasing their human overlords, and therefore being allowed to breed.

  11. Re:And racism? on Butterfly Unlocks Evolution Secret · · Score: 4, Insightful

    Firstly, sexuality and racism are different subjects. These butterflies are more sexually attracted to certain markings or patterns, which indicate the partner is of the same species. They aren't hiring other butterflies for jobs, nor pulling them up for minor driving offenses.

    There is no racism in finding yourself sexually attracted to certain racial characteristics such as skin colour.

    You ask, "Isn't racism a social form of speciation". No. Racism is racism. There are many reasons why this racist segregration would not lead to speciation, even if it were not a morally repulsive proposition:

    1) No reinforcement, i.e. segregration is not selected for. As far as evolution of humans is concerned, offspring of people of different races are not "weedy and less likely to thrive" as in the butterfly example, but quite the contrary. So from a biological point of view, we should not expect to find ourselves splitting into seperate species as there is no "reinforcement" (as mentioned in the article), but instead the opposite. Of course humans are still very much the same species, and are currently showing no signs of speciation, and comparing human races to butterfly species is stretching it.

    2) Very little gene flow is needed to prevent speciation. One "mixed marriage" out of one hundred is plenty to keep genes flowing between subgroups within a species. This coupled with the above (the offspring being strong and healthy) makes it nearly inevitiable

    3) Most people's concept of race is misguided. For example: Humans were originally black. So it's not surprising that there are people within all (eight?) major branches of our collective tree with black skin. Human movement and migration has lead to us all being much more related than you'd probably guess.

    4) Timeframe: butterflies may have several generations each year. Even so, the researchers in the article don't appear to even witness speciation in action, but takes a snapshot and explains how it has occured. Speciation takes a long time. It's likely to take 100,000 years for humans to start showing signs of speciation, that is, if there was an evolutionary push towards it. Justifying racism on the basis that your great great great great great [25,000 "great"s removed to prevent this comment from violating the "postercomment" compression filter] great great great great great great great great great grandson or daughter may belong to a different species as the person next to you, is pretty fucking stupid.

  14. Nuclear = green house gases on Ethanol More Trouble Than It's Worth? · · Score: 2, Insightful

    The mining, milling, and enrichment of uranium all produce significant greenhouse gases. In fact every stage of the nuclear fuel cycle produces green house gases. Let's not even consider CO2 produced in the building and decomissioning of the plant and facilities. Well we can't. No significant nuclear power plant has ever been attempted to be decomissioned.

    Further problems with nuclear include the unsolved problem of waste disposal, the high cost of producing nuclear power (it's actually much more expensive than many renewables), nuclear weapons proliferation, and of course apart from the Three Mile Island meltdown (26 years ago) and the criticality accident at the uranium reprocessing facility in Tokai-mura (just 6 years ago), there have been plenty of other nuclear accidents.

    Did I see say nuclear wasn't renewable? that's right. High grade uranium will run out in 20 to 50 years (pick your estimate). Leaving us with low grade stuff, which is even more CO2 intensive to mine, mill and enrich, and will also eventually run out (150 years perhaps).

    As for evolution being only a theory, the word "theory" has slightly different meanings in science and in every day speech. To quote an Evolution FAQ:

    In science, a theory is a rigorously tested statement of general principles that explains observable and recorded aspects of the world. A scientific theory therefore describes a higher level of understanding that ties "facts" together. A scientific theory stands until proven wrong -- it is never proven correct. The Darwinian theory of evolution has withstood the test of time and thousands of scientific experiments; nothing has disproved it since Darwin first proposed it more than 150 years ago. Indeed, many scientific advances, in a range of scientific disciplines including physics, geology, chemistry, and molecular biology, have supported, refined, and expanded evolutionary theory far beyond anything Darwin could have imagined.

    This model of allowing groups of cars through is the same as what naturally happens where there are no traffic lights, and cars and bicycles share the road. It is termed critical mass.

    The term "critical mass" in this sense, was adopted from an observation made by American George Bliss while visiting China. He noted that traffic in China, both motorists and bicyclists, had an understood method of negotiating unsignalled intersections. Traffic would "bunch up" at these intersections until the back log reached a "critical mass" at which point that mass would move through the intersection. This description was related in the Ted White documentary Return of the Scorcher (1992) and subsequently adopted by the Critical Mass movement.

    Perhaps the only difference with this traffic light system is it tries to preempt the "bunching up".
