    Not to be pedantic, but you mean the signal to crap ratio is getting smaller. And I totally agree.

  2. Re:Reputation on Ask Slashdot: A Cheap, DIY Home Security and Surveillance System? · · Score: 1

    The point of the gun and the dog is to protect you while you are in the house, and so you aren't caught unaware and unarmed if an intrusion occurs.

    Also, if the intruder is going to kill your dog, he doesn't need to borrow your gun to do it.

    You're right about the gun being an attractive target. That's why you don't tell neighbors or whatever that you have one. Once the burglar has broken into your house and found the gun, yes, it's a larger loss, but at that point he's already raiding all of your stuff. It wasn't like he came there for the gun, because if you're doing it right, he doesn't know you have one.

    I'm sure you're also right about the dog being complacent about the whole thing. I think the best you can expect from a typical housedog (one you don't mind having around your kids unattended) is a little forewarning and the possibility of turning off a very undetermined burglar.

  3. Re:Alchemy? on Scientists Build Graphene From Scratch, Atom By Atom · · Score: 3, Informative

    This comment on the main page does a better job of explaining what is going on than the article and summary.
    You are not doing a good job of explaining what is going on (mainly because it is hard to do in one article and is beyond the scope of what your editor wanted). Each different element has a differing ability to attract electrons, this is based upon the number of orbitals filled, or left vacant from their spot in the atomic table. In general elements react according to how many orbitals they have open. Carbon has 4 open spots in its orbital pattern. Hydrogen has 1. Thus when carbon and hydrogen react they can produce methane (CH4). Benzene rings are the basic structure behind graphene, they are particularly unusual because the shape of the orbitals are modified by the 3 dimensional shape of the ring of carbon atoms. This shape in turn, causes the P orbital to become displaced above and below the plane of the carbon ring. The voodoo or magic that happens here is what has everyone excited about graphene. This displaced orbital completely changes the properties of carbon. The only similar type of chemical properties that exist in our world are the properties of living organisms. Not surprisingly, living organisms are full of molecules that have benzine rings in them. What this article is saying is that we will be able to make new materials based upon carefully spacing the placement of atoms on a layer on top of the material that is shaped like the spacing in graphene. This mimics the deformation of the p orbital that carbon has. It is not exactly like it which is even more exciting because it will allow for even more specialized forms of material to be made. The electrons in the example were actually in a magnetic field made by the atoms of the material rather than from the surrounding area. This is an example of quantum mechanical effects effecting the broader material and is another exciting aspect of these experiments.

    Nano-tech like this will not directly allow the production of elements (gold, platinum ect.) It will make whole new combinations of materials that could not even be imagined by a scientist before this study. Reading between the lines here, what we are seeing is that contrary to current speculation in popular press, the limitations placed upon Moore's Law by the properties of atoms is not a bad thing. It will in all probability allow us to build materials and manipulate matter in ways that were blocked by our inability to control masses of specific atoms in specific ways. A bike built from the placement of individual atoms in specific places will be incredibly light, durable and cheaply made by machines alone. The boundary between living matter and dead will be much harder to see because materials used in ordinary items will have some of the same kinds of strength, regeneration, self replication, and beauty that we associate with living things."

    I don't understand what your rationale is here.
    If you divide the number of crimes perpetrated by one group by the number of group members, and then take the ratio of those values, you'll get a measure of how often one group commits a crime versus another.

  9. Re:only going to get worse... on Smart Meters Wreaking Havoc With Home Electronics · · Score: 1

    Additionally, smart meters used for gas can save lives. Let's say one of your copper lines rupture due to decay, and your gas usage spikes accordingly. In the old days, it would take a month of this high usage before gas service personnel was notified so they could investigate. A month is a long time to have that dangerous of a situation existing in your home. At the gas distribution company my mother works at, they have been able to reduce the response time from a month to a week for these cases.

  10. Get a seedbox on Ask Slashdot: P2P Liability On a Shared Connection? · · Score: 2

    The best thing your room mate can do (besides not torrenting at all) would be to get a seedbox in another country and use private trackers exclusively. This way, your IP address is never exposed to the swarm. You can download all the files from your seedbox to your house computer using encrypted FTP. You can rent a seedbox, which is just a rented virtual server that is already setup for torrenting, using prepaid credit cards and false personal information. You can get seedboxes in countries with more lax IP laws such as The Netherlands. It's still best to avoid public trackers as an extra layer of protection. I know several people that have used this route for years and they haven't had any trouble.

  19. Meh on A New "Medical Lab On a Chip" For Every Home? · · Score: 3, Interesting

    This guy isn't talking about anything new.

    The concept of a 'lab on a chip' has been around since at least the early 90's. I know from talking with my my boss that in the 70's, chemists at MIT were expecting tricorder devices to be implemented sometime in the late 80's.

    We see some progress in this field, but the ultimate goal of a tricorder device is a long way off. Home pregnancy tests provide a similar functionality, however purpose built for one assay.
    With careful planing, an assay can be marketed for use by consumers, but I'm leery of talk of talk about 'one device to rule them all' when it comes to this sort of analysis.

    The key is that this sort of analysis is not as simple as throwing a sample through a mass spectrometer and identifying the compounds like Sean Connery in Medicine Man.
    Bioanalytical chemistry (which is what this is) is not magic. Physical or chemical information has to be obtained, and this is generally requires the use of reagents such as labeled (with something we can use to detect them, such as radioactive tritium, or a fluorescent compound) antibodies and antigens. I just don't see these sorts of things being sold to consumers in anything but a black box form, where the consumer does not interact with the reagents in a meaningful way. Sort of like how pregnancy tests are done.
    This truth implies that each analysis will have its own one shot kit, providing a qualitative assessment of whatever is under investigation. Sure some of the hardware can be externalized, such as a simple fluorescence spectroscopy instrument, but still, cartridges for whatever test will still need to be purchased. Unless this guy has come up with some incredibly radical--and earthshattering analysis techniques, I've got to say he has either been misquoted by the reporter, or he is blowing PR smoke.

    Funny coincidence is that I am writing up a research proposal for one of my grad classes with the goal of quantifying Early Prostate Cancer Antigen 2 (EPCA-2) in serum using a microfluidic device using forster resonance energy transfer (FRET) as a detection method. I can see a device commercialized for this purpose, but it would be one shot and limited to this analysis.
