100% agree...Kill the penny, kill the nickel, kill the quarter, kill the $1 and $5 bills.
The dime (the physically smallest coin) becomes the smallest denomination. 10 of'em to the dollar. If you absolutely have to, create a 50 cent piece that's a bit larger than the dime.
Build a dollar coin that DOESN'T LOOK LIKE A QUARTER, goddammit. Even the gold Sacajawea dollars, after a couple of years, tarnished to look like an older quarter. Build it with an external polygonal rim, or put a hole in the middle of it,. Maybe make it about the size of a penny, or nickel so coin holders in cars, etc., will hold the new dollar..Build a 5 dollar coin if you must, just a bit larger.
In my world, that'd be two coins ($0.1 and $1.0). The numismatists (who single-handedly keep the penny alive) would probably require 4 ($0.1, $0.5, $1.0, $5.0). Then, three bills - $10, $20, $50. Despite my misgivings about losing a cash economy, the ease of counterfeiting (especially at the nation-state level) probably means that making higher denomination bills is a poor choice.
Not so much. A spherical shell of reasonably dense material (depleted uranium, say) surrounding the turkey and acting as a "pusher" will likely flatten any non-spherical portion of the turkey during the implosion.

How often would you ever use the full acceleration of a motorcycle?
Daily, to keep one's digestion regular and one's head clear.
Yes, there is no reason on earth (other than pure joy) to put a 130 hp engine into a 500 pound motorcycle. We could all get by on 150 cc, 250 pound scooters. But what fun is that?
Generally, poor aerodynamics and an engine that isn't tuned for max mileage. Once you're going down the highway, the weight you're carrying doesn't have that much impact on mileage. It has a huge impact on stop-and-go driving, though.
Actually, the receiver will generate very low level signals that propagate out from the device as part of the Rx circuits. This is no big deal - unless your GPS is in your pocket, you're in the window seat, and the plane's GPS receiver is mounted between the plastic interior skin and the outer aluminum skin (what, you thought the plane's GPS RF section was in the cockpit?). Your GPS receiver will be putting out a tiny signal, but it may still swamp the signal being received from the satellites 12,000 miles (20000 km) away.
For example, there was a report to the NASA pilot safety program: "In 2007, one pilot recounted an instance when the navigational equipment on his Boeing 737 had failed after takeoff. A flight attendant told a passenger to turn off a hand-held GPS device and the problem on the flight deck went away." (http://www.nytimes.com/2011/01/18/business/18devices.html). This is apocryphal, and even if true would likely be the result of a badly damaged or badly designed device that didn't meet FCC regulations - but if you're going to allow a million people to carry on any electronic device they might have, in whatever condition it might be in, you're going to run into these kinds of receive-only-devices-that-transmit-worrisome-amounts-of-unexpected_RF.
This (http://gpsinformation.net/airgps/gsm_intf1.pdf) discusses the likely interference caused by phones in an aircraft; the big worry isn't so much modern planes and electronics, as it is electronics and planes designed before 1984: "From the above, by comparing the test results with the qualification levels given in Section 2, it can be seen that interference levels produced by a portable telephone, used near the flight deck or avionics equipment bay, will exceed demonstrated susceptibility levels for equipment qualified to standards published prior to July 1984. Since equipment qualified to these standards are installed in older aircraft, and can be installed (and is known to be installed) in newly built aircraft, current policy for restricting the use of portable telephones on all aircraft will need to remain in force." Of course, this document is 12 years old now, discussing designs that were current 16 years previously.
As a matter of fact, I don't believe it will be a travesty. But I hold the (apparently) unpopular opinion that the LOTR movies were an excellent adaptation of the books - not a perfect mirror of them, but the best that could possibly be done when going from printed page to movie screen. Because of that opinion, I'm willing to hope that The Hobbit, as a movie, is the same kind of excellent adaptation.
That said, I don't know where they're going to get three movies worth of material and retain the pacing that worked well for LOTR.
Interesting. I always thought anti-fuses were a one-way kind of thing - start at high resistance, and program them to low resistance, with no reverse path. I didn't know that they went both ways (as it were).

The HP Memristor Debate

· Score: 3, Informative
The comment above (http://hardware.slashdot.org/comments.pl?sid=3004785&cid=40771055) is more informative - a real Memristor is defined in terms of electric and magnetic fields. The HP memristor looks just like a real one, but doesn't involve a magnetic field at all.
I have a charger at home, one at work, and a 12V one in each of my family's cars. Still pretty simple, but causes an issue if I change phones. Of course, I picked up a wife too, and if her phone didn't have the same charger as mine, I'd have to divorce her. Then, through mechanisms still somewhat mysterious, we ended up with two children. They have Nintendo DS's, and a portable DVD player for the car (all seperate proprietary chargers). My wife bought an iPad (30-pin), and the kids are getting old enough that we're considering getting them iPods (which, if we wait for the new ones, will have the 19 pin).
Have you kept count of how many charging cords I need to have yet? Wouldn't it be nice to have one or two identical chargers in each car and in the house, and anyone could charge anything, as opposed to having 5 or 6 different chargers?
This is a situation where Apple has their head firmly inserted into their rectum. An innovative, customer-oriented company would have put a micro-USB connector with standard USB charging protocols. If you want Audio out, or Video out, or whatever else comes out their dock, have it come out digitally and convert it in the dock.
Because RSA-2048 keys (twice the length of RSA-1024) take about four times as long to operate on (http://www.cryptopp.com/benchmarks.html). RSA-15360 (which is roughly the strength of AES-256 (http://csrc.nist.gov/publications/nistpubs/800-57/sp800-57-Part1-revised2_Mar08-2007.pdf, page 63)) would take about (15360/1024)^3 = 3300 times as long as RSA-1024 (http://www.design-reuse.com/articles/7409/ecc-holds-key-to-next-gen-cryptography.html). This isn't a big deal for your local PC, where a single signature verification might take 250 ms rather than the sub-ms that it does with RSA-1024, but it has huge impacts on the servers that you're talking to - imagine increasing your server load by 330,000%.
The same AT&T that tells Congress that competition among telcos hurts consumers?
Well, they were right from a technical point of view, but not from a cost point of view.
Phone service now is far cheaper than when AT&T was in control of long-distance, and has far more unique providers (Multiple long-distance providers, Skype, Cell Phones, VOIP, etc). But, the quality of phone calls is vastly inferior to what AT&T was selling. Get on a landline, and talk to someone on a landline someday. No dropped calls, no half-second latency that causes one person to talk over the other, etc.
Hardly ever do I see stationary machines doing useful work. Mostly what I see are moving machines engaged in meaningless activity that has no application in the real world
LA and the surrounding basin (all the way east to Riverside/San Bernardino) isn't a desert; there's plenty of humidity in the daily onshore breezes and the 15 inches of annual rainfall to keep it out of that category.
But, there isn't nearly enough rainfall/runoff to support 13 million people there.
I thought exactly the same thing when Google went IPO and the Investment Industry was pushing a stock price of $75. I convinced our investment club (remember those?) that they didn't have a business plan, had no obvious source of sufficient revenue to sustain the share valuation that was being discussed, and that we shouldn't buy in.
You're absolutely right. Let's assume an LED running at an 20 ma of current. An LED can't be connected directly across 120V (well, actually it can, and is amusing in a small-firecracker way), so a dropping resistor is used to reduce the current flow through the LED when on to the 20 ma that the LED can take. The combination of the LED+resistor end up with 120V (ignoring half-wave rectification and RMS voltage values) across the pair, and 20 ma going through them, for a combined power of 2.4W.
The LED isn't drawing 2.4w (which, by the way, is a nice bright flashlight), but the lighting SYSTEM is. An 80% off-line switching supply could be built that provided the.06W that the LED is actually using, but your power strip would cost $10 more.
You haven't been here in July or August, have you? Dewpoints are generally between 50 and 65 degrees F during those months (although, with an outdoor air temperature of 110F, the relative humidity is still low). Currently, we have a relative humidity of 9%, and a dewpoint of 25F, so it's pretty dry, but an evaporator operating below 25F will still condense water...
I haven't been following the recent reporting on this case; did somebody find some evidence between the time (as his girlfriend reported) this: “He said this man was watching him, so he put his hoodie on,” she said. “He said he lost the man. I asked Trayvon to run, and he said he was going to walk fast. I told him to run but he said he was not going to run. Trayvon said, ‘What, are you following me for.’ And the man said, ‘What are you doing here.’ "
