  1. Re:processing time claim is very optimistic. on Briefcase Sized DNA Analysis System · · Score: 3, Informative

    I imagine they can do it in the time they say. I also imagine the results are very simple, like looking at one STR sequence and counting how many lengths of it are in the person's genome in a process similar to qPCR, less RFLP/southern, as parent seems to think. Despite what TFA might imply, I don't think there's endonuclease digestion involved. I may be wrong, and they could have a really, really fast breifcase thermocycler making this work. Maybe, doubt it.

    I'm not any kind of STR expert, but from cribbing Wikipedia http://en.wikipedia.org/wiki/Short_tandem_repeat, here's my impression of what's going on with this kit:

    1. get cells = blood and semen. yum. In fact, I'd infer this kit is probably a "semen-only" deal in practice, which makes isolating the DNA that much easier, since semen is largely DNA.
    2. isolate DNA. Do it yourself, kids! (http://learn.genetics.utah.edu/units/activities/extraction/) 2-5 minutes with a kit.
    3. PCR. Here's where things get interesting. What are their primers? I think they're using 5-10 nucleotide STR sequences that are already conjugated to a fluorescent dye. Since STRs for human identification use are just, according to wikipedia, 4-5 STRs (10-50 nucleotides) long, each cycle can probably be as short as 30 seconds. With ramping the temperatures we can call that 1 minute per cycle. How many cycles do we need? 10 cycles gives us 2^10 copies of the original STR, that's (biologist math)1000 copies(/biologist math). Add 2 minutes for our hot-start polymerase, and that's 12 minutes for PCR. Whoo! It well may be less, i.e. shorter elongation, fewer cycles. This is where they're claiming to save time, so who knows.
    4. electrophoresis. Undoubtedly capillary, you can see it in the photo (at least I can), and since we're looking at stuff that's only 75 nucleotides max, can be done very quickly. I don't really know capillary gel electrophoresis, but it apparently kicks the shit out of slab gel electrophoresis: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=330505. We'll call that 10 minutes, lol. Could be a bit more? Balances with the PCR.
    5. Of course, we added a 10-100 nucleotide standard conjugated to a different fluorescent species from the primers (i.e. the primers glow green and the standard glows red), so we can use our shitty little built-in 2-wavelength spectrophotometer to see where our unknown sample's bands are.

    And now we have our data! And that only took... 25 minutes! Of course, this isn't a full-blown RFLP, like parent seems to assume. But just for doing a quick-and-dirty count of STRs, this could work. That's how I'd do it. Maybe I just invented a competing type of kit, lol. In any event, looking at the picture, I get the feeling their pipettes are crap.

    Note this doesn't show how many repeats of a given legth the accused has, so the asshole could have 3 5-repeat ones and 2 4-repeat, and the machine would show that as being the same as a person with 1 of each. Also, they may use more fluorescent dyes to look at more STR sequences without too much difficulty. But in general, the samples will be unclean at best, total crap more often than they'll like to admit, and, in the end, only good as a blood-type-and-then-some test. How juries will react to this, I don't know.

    To get even farther from parent, the real threat to your privacy is coming from gene chips, the next generation of sequencing technology. This kit is comparatively rudamentary, and obviously expensive. Yet more overhyped crap, whee!

    Yeah, the arguments in TFA were dumb, but the overall point was right. Ubuntu gives me a crappy little "share a folder" dialogue, then, when it doesn't work, I have to crawl the net to find out how to edit the samba config file. There's no 'ramp' leading from simple, "easy to use" (but non-functional) GUI tools to the steps needed for a tech-inclined non-CS-major to get the thing working. Ubuntu gives a half-functional, efforless setup for Grandma on top of the only-accessible-to-hardcore-geeks core of Linux. As someone in the middle, I can't get simple functionality out of it.

  3. Re:Security of Users vs Root security on A Gut Check On Gutsy Gibbon · · Score: 1

    It doesn't matter.

    I'm a lay user of Ubuntu and I can't get that shit to work. It's five minutes before I'm editing config files and trying to copy files - except I can't, because I don't have permission, leving Ubuntu unusable. I managed to share my drive, but my P2P program mysteriously stopped working after an update.

    After a lot of digging, I found out the many directories it's spread across, but I have no idea what to do, even with the forums' advice ("install java in a new directory and point the program there"... OK, I'll "point" it, ponce, WTF?). And even if I did, I couldn't, since the super-secure OS won't let me modify them. And since I'm a simple end user, I'm left doing chown -R 777 whenever I need to tinker (which is often). Hella secure!

    Part of it is that the online guides expect things are going to go well. They don't tell you what to do when the inevitable happens and packages don't install right or the system settings GUI doesn't actually modify system settings.

    Linux for humans, my ass. Did they even have a human try to use it? Just watch your non-geek cousin try to use the OS for a half day. You'll see a dozen stupid little things that can be changed or explained to make it usable. Instead it seems they're running off some asperger-y ideal of "usability" that holds specific points (e.g. no hand editing config files) above the overall experience that Linux can offer at this stage of it's development.

    This root/non-root thing is the same. Why can't I modify my system files when I need to, using the GUI? Why can't I enter a password, instead of just being told I don't have permission? It's so stupid. I - I can't even go on. Fuck this shit, I'll find a PowerMac G4 to hold my storage.

    Nobody likes Uncle Scam up in their crotch. But what drives Libertarianism's bizarre economic ideas?

    Jost et al (2003) blew up this idea: people choose an ideology to make themselves feel good. So let's talk about Libertarianism as motivated social cognition!

    Libertarainism means wallowing in how "smart" you are. You don't need the government to help you, you're smart! You don't need the government to tell you what to put in your body, you're smart! Oh, those pathetic souls voting republicrat, they don't understand. But you do, you're smart!

    That's all fine, fine. Who the fuck likes the nanny state, who wants to reward irresponsibility? But then libertarianism turns stupid: radical deregulation, even scrapping the minimum wage, ending all public services that aren't gun-centric, etc.

    No, it's stupid. I'm not going to explain it: I cited Jost et al (2003) so I could get to the heart of libertarianism: fuck-you-ism.

    The frothing Objectivist side of libertarianism is chock full of nerd rage. It is pure misanthropy. Overweight coders with testosterone poisoning. People with high IQs and the social skills of a busted levee, cursing the shitty world that dragged them into a miserable, lonely existence. An empty life of shame and hatred motivates the economic side of libertarianism and its bizarre ideas of "self reliance" and the "night watchman state," codewords for social-Darwinism and a Banana Republic.

    I'm not saying all libertarians are misanthropes. Some just give lip service to the economic side, while piling on the caveats. Some are non-ideological people reasonably sick of the two-party system. But let's not kid ourselves about the dark core of libertarian ideology. Every ideology has its dark core. But libertarianism seems to have a black hole at its center, a hole of loneliness and hate, and that makes me sad.

    But I believe that with faith and effort, even the most awkward person can craft a satisfying, flesh-space social life. First, admit your pain. Then realize the universe is full to the brim, and you're swimming in it. Then take that power, that relief, and keep trying different things. Again and again. It'll hurt like a bitch, but eventually you'll get there! If you don't feel the universe to be like I described, try meditating, exercising, joining a spiritual community, etc.

    That may sound stupid, but it's the wisdom of the ages. You'll feel so much better once you get to the other side of your pain! Good luck.

It's not a big deal, except in certain cases, and not worth getting worked up about in either direction - making this list or criticizing this list. I just appreciate the paranoid spooks telling me what a spy looks like - they probably know, so it's good information. As for "restricting freedom," this doesn't sound like any sort of policy that's going to be enacted. It's just an informational briefing the feds are offering! Lighten up!

To use your social security example: we can change SS to just go to those that need it, but the electorate has a history of coming to loathe poor people who get government help and destroying programs that aren't universally applied. E.g. welfare, affirmative action. You'd add social security to their ranks with your policies, and set it up for destruction. See what I'm getting at? So you can muck around in your particular logic, your justifications for tax cuts, etc, but YOU'D BE HAPPIER IF YOU JUST SUPPORTED THE WELFARE STATE - because anytime you start trying to grasp you money so tightly that you justify your greed as altruism, you're going against your better nature.

    Behavioral neuroscience has been putting out some interesting findings (look at any issue of Scientific American Mind), even if they are easily distorted and used as excuses for crappy behavior. That includes, IMHO, conservatives who are looking to neuro to justify their worldview - selfishness, selfishness, selfishness. But reality cuts in many ways, and at the end of the day science is going to reflect the whole of human nature expressed across all society's stripes. So while there is plenty of work supporting the reality of selfish, cowardly and lazy citizen that conservatism presupposes, the other side of human nature is becoming equally represented, in research like TFA talks about.

    On an even happier note, game theory continues to undercut the "rational economic actor" that underlies the precious free-marketeering so many slashdotters jerk their knees to... All in all, it looks like, while behavioral neuro is going to spawn a thousand shitty covers of Time Magazine ("Are You Hard-Wired to Hate Mexicans?") at the end of the day, a lot of bull is going to get cut, and people will be brought down to earth, de-ideologized.
