If you guys won't RTFA fine, but at least read the summary. This scheme includes modifications of the lines to eliminate the interference problems.
How about you read the fucking article. It clearly says that the lines are modified to eliminate interference to the data signal, not to outside receivers. As an electrical engineer, I can assure you that this idiotic idea will radiate noise like crazy over a wide band of frequencies.
You've probably seen those little cylindrical doodads on cables for game controllers, power supplies, and so forth. Those are ferrite cores to keep radio noise from escaping from cheap, crappy electronics. If they aren't used, the tiny (millivolts) stray signals from the digital chips will stroll down the wire and fly off into space. The signals in power line communication are the same, except that you can't filter them out because the whole point is that they travel down the full length of the wire to deliver information.
Consider a cloud that has net angular momentum. As the consitutents of the cloud collide, their random orbital motions get turned into heat. After a long time, all that's left is the average angular momentum: a bunch of objects orbiting in the same direction in the same plane.
It doesn't turn into a single spinning ball because as the constituents collide, they sometimes stick. The more the empty spaces between them grow, the less often they collide. (Collision rate scales as the third power of the mean free path.) In a mature planetary system or galaxy, collisions between major bodies are so rare that they're nearly unheard of.
Worse, crashing into lead will cause high-energy cosmic rays to spew even more secondary particles. Unless you plan on using meters of lead, you're better off with a thin shield that can just barely take out the low-energy stuff.
Making things work in space is hard. They have to survive extremes of heat, not generate static electricity that zaps the solar panels as they're peeled off, not leave a residue that collects dust like crazy, not prematurely curl up at the edges, not fall off and get tangled in the wheels, and so forth. Guaranteeing all that with high probability would have required a major engineering program.
I think it's much more likely that Apple's HCI people recognize that a two-button mouse is a kludge for developers who don't know how to build a proper menu system.
Don't be silly. Quite a bit of software is necessarily modal, especially graphical editing. With multiple buttons, you simply press a finger to access the other mode(s). A crippled one-button mouse instead constantly drags your eyes and concentration off the work. Now that's a good design choice on a toy meant for novices, but for professionals trying to become one with the machine that Morse code interface doesn't fly.
Why would banning by IP addresses by effective at the TypeKey level when it's already been proven to be ineffective at the individual weblog level?
Consider M blogs and a spammer with N zombies in his botnet. Banning IP addresses on individual blogs means that M×N spams will get through at a minimum. Centralized banning would only let N spams get through. If M and N are large, that's easily hundreds of millions of spams prevented.
Other than that there are few examples of huge data usage on the desktop, apart from contrived examples.
High resolution imaging, both still and motion. Quite a few people do this, both professionals and amateurs.
Various technical professionals also deal with huge piles of data.
And even boot time is an important consideration. I've seen some dumbasses in this thread saying that "shaving 10 seconds off the boot-up time is not much to show for the expense". Except of course for the legions of programmers and QA people who reboot their virtual machines all day long.
Consider the situation at some moment in time after the drives enter service. At that point, the probability that a particular drive will have failed is pf1. The probability that that drive will still be working is pw1 = 1 - pf1.
Assuming that failures are independent, the probability that N drives will still be working is pwN = pw1^N = (1 - pf1)^N ~= 1 - N*pf1. The failure rate for N drives is thus approximately a factor of N larger than the failure rate of one drive. Q.E.D.
In reality, failures are not independent. Many failures come from design flaws, systematic manufacturing defects resulting in bad lots of product, improper cooling, high workload, power supply failure, and mechanical damage. ("Common mode failures" in engineering jargon.) Therefore the real-world joint failure rate will be considerably worse than N*pf1.
The example I gave was for myself, but I have set up fire or six computers with striping RAID set ups in the last few years and seen several others, the only problem I saw with any of the RAIDS was an xfs filesystem problem, NOT RELATED TO THE RAID. The benifits far outway the risks.
The plural of "anecdote" is not "data". The only proper tool for dealing with rare events is statistics.
Does it matter what the internal temp of the system or CPU is as long as its within normal operating parameters?
Reliability. Cooler chips draw less power, which means the Vcore regulator tends to last longer. You also get a greater safety margin for cooling problems.
I hear people talk about this like it matters. Maybe if you were calculating cooling on a room with hundreds of systems, but for Joe Jackoff and his home PC, who cares?
Joe's cat sheds into the computer. He puts it in a cubby hole. He never opens it up and cleans the heat sinks.
What I took away from this article is not how cool and useful intelligent fasteners might be, but how they promise to keep you from having control over the vehicle you purchased and legally own.
Not in the US. That contest was already fought with manufacturers who tried to void warranties for not using their motor oil and replacement parts. Vendor lock-in and unfair warranty restrictions are now explicitly illegal.
Compiled SQL is faster. This is purely a performance enhancement.
One that can be critical for hierarchical data. A stored procedure will save one round trip from the app to the DBMS for each level of hierarchy that has to be traversed.
That's the soul of n-tiered architectures, they're supposed to bring that kind of flexibility along with the use of tiers...this kind of flexibility is the point.
Reminds me of something I read: "We have an n-1 tier approach. No client, just multiple layers of server.";-)
Crack can withstand heat sufficiently to allow it to be delivered via the lungs.
Crack can withstand heat sufficiently to be sublimated into the vapor phase.
This is important. The high is quicker and more intense than cocaine, as is withdrawal.
I don't have any hard data, but I strongly suspect that nebulized, inhaled cocaine works just like inhaled crack. If any adventurous, well-supplied experimenter would care to check, please post a reply...
Nicotine! That's a really good idea. Stuff like cocaine, heroin, and so forth is not very potent. You have to take hundreds of milligrams to get a major effect, which is way more than antibodies can realistically soak up. But nicotine is only a few milligrams a dose. Antibodies might stand a chance. Get a person clean, vaccinate them, and then a moment of weakness won't reactivate the physical dependency. (Although who knows about the phsychological addiction...)
Therefore the important question is, what part of the psyche/brain/whatever are these "vaccinations" destroying to prevent people from becoming addicted to drugs/smoking/alcohol/sex/chocolate/carbohydrates/ (insert your preference here)????
They don't destroy anything. They cause the patient's body to produce antibodies, which are big grabby molecules that hold on to the drug of interest. Since the drug molecule is glommed onto this giant pincher, it can't get to the nerve receptor to do it's dirty work. The bound "immune complexes" either get chopped up by enzymes, or the drug gradually desorbs and gets disposed of in the usual way.
Of course, this will work very poorly. The body doesn't make antibodies in large quantities. Enough to bind even a hundred milligrams of drug would be an insanely huge amount of antibodies. It would only really be effective against ultra-trace drugs like LSD or the belladonna alkaloids. For stuff like ketamine, you'd just have to do a line or two to saturate the antibodies, and then start doing lines for fun. It'll just raise the cost a little for recreational users. Addicts won't be affected because they'll tend to keep the antibodies saturated at all times. It will, however, probably be enough to trigger immune hypersensitivity reactions, and maybe autoimmune diseases.
So: Expensive, minimal benefits, and heavy costs. That pretty much guarantees the government nannies will love it.
Well, crack cocaine produces a more extreme high than the powdered form. Wouldn't you agree that crack cocaine is more debilitating?
No. Crack is cocaine. They affect exactly the same neurotransmitter systems in exactly the same way. The only difference is that a given amount of money will buy more doses of crack than of plain cocaine. Crackheads use crack to stretch their meager incomes, not because it's more addictive.
Research is NOT discredited by conflicts of interest. It is discredited by factual evidence to the contrary, which has in fact been done for the MMR-autism hypothesis.
Probably the most common complaint after surgery is poor night vision, to the point that some people can no longer drive at night. This happens because your pupil opens up big in the dark and can allow light to pass through the rough edges of the zapped area.
Could these people benefit from a contact lens with an opaque band around the edge?
I don't understand from your post what myopic eyesight improves. Can you focus closer than 4 inches? Kind of like Macro mode on a camera lense?
That's exactly how it works. I have approx. -8 diopter myopia and can focus to within a few millimeters of the tip of my nose. It gives high-resolution close-up vision, exactly like a macro lens on a camera. I'm a EE and it comes in handy for looking at tiny surface mount electronic components.
I'd gladly give it up to be rid of glasses, though. For me the worst part about glasses is chromatic aberration, which produces rainbow fringes that get progressively worse as you look away from straight ahead. At 45 degrees from straight ahead it gets difficult to read a computer screen, and fine details are lost completely near the edges of the lenses.
What the hell is wrong with people?! Is chicken pox -- as a child -- really so bad?
The varicella-zoster virus hides in cells for the rest of your life and can later reactivate during adulthood to cause shingles, a rash that can be excruciatingly painful.
For crying out loud, we're not talking about polio!
The virus preferentially invades nerves. Complications can include neuralgias, including blindness. Encephalitis resulting in brain damage is also possible.
IIRC the severe complications are mercifully rare, and plain shingles is fairly rare.

Nah. It's no different than the government issuing bonds to pay for the project. Either way, the private investor gets their profit.
