    Mod parent up for ideas that aren't vague or hand-waiving like most of the other comments here.

    In the modern surveillance state, reality may end up reflecting what you describe in your second paragraph.

  3. Re:Needs oversight on Personal Genomics Firm 23andMe Patents Designer Baby System · · Score: 1

    False analogy, because one of these things has to do with the availability of potential mates to different sociodemographic categories, whereas the other one has to do with access to genetic screening and engineering technology. The difference is, that although there is significant overlap now between the categories best advantaged in each of these contexts, that will change as the price of the latter falls due to sci-tech progress, bringing it to the masses over a couple of decades. On the other hand, in the former case, no such change is possible, for obvious reasons. Your argument is bunk, as is the comment about teenage pregnancies, as there is a consistent downwards trend since recording began, despite a spike in the 1960s.

    Austerity doesn't really help you because it depresses the economy further by decreasing aggregate demand.

  5. Needs oversight on Personal Genomics Firm 23andMe Patents Designer Baby System · · Score: 2

    This needs to be regulated because the result of many people individually selecting for characteristics can have negative effects on the overall human gene pool. I've already elaborated on this under another recent story: http://science.slashdot.org/comments.pl?sid=4173815&cid=44775829

    > Their sleeping patterns are different from adults, and they do require additional sleep

    Looks like we, as adults, also naturally require different sleep patterns than we engage in the last couple centuries: https://en.wikipedia.org/wiki/Segmented_sleep#Segmented_sleep_as_a_historical_norm

  7. Why, Opentaps, of course! on Ask Slashdot: Best Open Source CRM/ERP System For a Small Business? · · Score: 4, Informative

    I'm amazed it wasn't mentioned in the summary.

    It's what we use. Very powerful and flexible and it covers most ERP areas. It also gives you easy path to running in the cloud if you want to do that, though we're running it on our own machines.

  8. Key word: "disappointing" on NASA Rover Fails to Turn Up Methane On Mars · · Score: 1

    Mars has a long history of unfulfilled wishful thinking associated with it. Let's not forget Percival Lowell's early telescope observations of the planet leading him to claim it was covered by canals undoubtedly built by an extraterrestrial civilization. Mumma and Meyer's are the modern day Lowells. Other posts in this discussion already have the large error margins in the satellite observations covered, and the scientists behind this ought to have known better. But hey, NASA needs the hype, right? After all, they managed to do the impossible over the last 40 years and make space boring--complete with a shrinking budget.

  9. Re:True Bummer for our friends in Russia on Russian Government Takes Over Country's 289-year Old Scientific Academy · · Score: 1

    Mod parent up. Lysenkoism is a great example of Russian (Soviet, really) pseudoscience.

  10. Maybe we shouldn't be remembering dreams on New App Aims To Track Your Dreams · · Score: 2

    Have any of the people that push dream diaries, including this modern version, thought that perhaps there's an evolutionary reason that we don't often remember our dreams, and most of us, rarely in great detail?

  11. Re:Awful calculation - the real answer is almost z on It Takes 2.99 Gigajoules To Vaporize a Human Body · · Score: 1

    You forgot to address the obvious question: where the hell does the resulting 100 to 200 cubic meter cloud of water vapor go?

  12. Re:Self Bootstrapping Death Ray on It Takes 2.99 Gigajoules To Vaporize a Human Body · · Score: 1

    Forgot to add: the way to approach this in a sci-fi is to invoke exotic physics, such as strangelets https://en.wikipedia.org/wiki/Strangelet which can convert ordinary matter into strange matter (maybe).

  13. Re:Self Bootstrapping Death Ray on It Takes 2.99 Gigajoules To Vaporize a Human Body · · Score: 1

    How on earth did this get modded up? It can't work like this because most of the energy released by fusion is in the form of neutrons and neutrinos, which cannot be captured by the plasma unless it has many orders of magnitude more density and thickness. As for the thermal expansion resulting from the initial fusion, it would overpower the containment field by orders of magnitude as well.

  14. Re:Self Bootstrapping Death Ray on It Takes 2.99 Gigajoules To Vaporize a Human Body · · Score: 1

    That won't work because the body's non-water component doesn't contain enough chemical energy to even vaporize all the water.

  15. Re:Since when did a phaser VAPORIZE its target? on It Takes 2.99 Gigajoules To Vaporize a Human Body · · Score: 1

    Humans are basically made of water, and a little bit of carbon materials. Far before you reach the 80kK degrees you're talking about, that water will vaporize into a cloud of 100 to 200 cubic meters--generating an explosive expansion that will blow away the phaser shooter in the area.

  17. Re:Murder? Possible and maybe practical on Man Killed By His Own Radio-Controlled Helicopter In Brooklyn · · Score: 1

    Difficult but not impossible. The specific frequency hopping algorithm of this model has been reverse engineered, as I posted in reply to someone else in this discussion, and with a software radio it's not that hard to synchronize to this. If you have a powerful transmitter and/or big antenna, you can override his signal. Of course, you can just use a high power jammer as well, which is much easier--engage it only when the chopper is close to the mark. But as I said, I don't think this is likely, just that it's a small possibility.

    And yet, Schneier recommends encryption based on it over elliptic curves (though, to be fair, the latter is recommended by the NSA).

  23. Invidivual vs. population and genetic monoculture on NIH Studies Universal Genome Sequencing At Birth · · Score: 1

    Most prospective parents would be inclined to select for similar traits. When this is done on a large scale, it would lead to decrease in human genetic diversity. Now, to anyone familiar with agriculture, the danger of monoculture is well known. This is not viable in the long term, and in a dynamic environment is likely to eventually lead to extinction. This is not to say we shouldn't use some level of artificial selection, but it is very important that it's done carefully and is globally coordinated, with attention given not just to individual preferences, but also the potential deleterious effects on the future human gene pool.

    A classic example is the HBB->HbS mutation, which is common in some populations in malaria-heavy regions. If you get a copy of the mutant gene from both parents, you get sickle cell anemia. A perfect target for our would-be eugenicists, right? In the heterozygous case, however, where you get one copy of the mutant gene and one normal one, you get protection from malaria.

    As an aside, screening should be done as early as possible, as with many genetic diseases there is no practical treatment (and there won't be any time soon), and abortion is the only alternative. Preferably, it should be done before the brain regions correlated with consciousness develop in the fetus (while consciousness' neural correlates are not particularly localized, certain regions discovered by Damasio et al. are required--for example, the anterior cingulate cortex).

    I don't believe you. The algorithm has been reverse engineered: http://www.rcgroups.com/forums/showthread.php?t=1759502 Anyone skilled with a software radio could eventually synchronize to this and then just need to put out a more powerful signal.
