AMD has shown that the seperate code path executed on AMD processors runs SIGNIFICANTLY slower than simply not differentiating processors and just running the P4-optimized path.
That abstract is pretty specific in its description of the system. In patent negotiator speak, it's a "narrow" patent. Narrow patents generally cover a very specific implementation (used to prevent direct cloning of a product in most cases), but due to their specific nature are easy to work around.
Essentially, this patent doesn't cover CaO heaters in general, it covers this particular cup design. It wouldn't be too hard for any competitor to develop a cup that did the EXACT same thing without infringing on that patent because it's so narrow and specific.
WiFi transmit power for almost all cards is 25 mW. 100 mW is the max legal limit without using automatic power control measures (reducing power when it's not needed) The max legal limit for WiFi is higher (There are even 1W amps), but 25 mW is the max from almost any laptop, and anything more than 100 mW without an external PA is unheard of. (I know of one card in existence that had transmit power over 100 mW)
And as to stray emissions from the laptop itself - WAY less than the 1/10 W (100 mW) you mentioned, guaranteed. Almost surely less than 1 mW. There's no way the FCC would approve any device that was an interference source with 100 mW transmit power. Hell, 1 mW of unintended emissions is probably not allowed. RF-wise, computers (especially laptops) are very quiet.
The Pentagon is making a database of the poorest and most underprivileged high school students in order to hook them in to military service.
At my high school, which was in a relatively wealthy county, there were almost never military recruiters, and very few students went into the military. Those that did would do so via the rather prestigious military colleges (U.S. Naval Academy, etc.).
Meanwhile, I have relatives that live in upstate New York. Their school district is in a relatively poor section of the country, and they have recruiters almost permanently stationed in the high schools, preying on the students. At this point, even if parents complain, the school can do nothing about the recruiters' presence due to the No Child Left Behind act.
Unfortunately, the processing is done by the network provider (your phone sends pseudorange data to whatever tower it's talking to), and with nearly all providers/phones, the data is not accessible to the end user.
A small handful of phone/provider combinations allow the user to access the information, but not many.
A few do, but not many. In many cases they are "dead reckoning" systems that count wheel revolutions and heading changes due to steering, and not actual inertial navigation.
Probably 90%+ of current automotive navigation systems are straight GPS. 100% of add-on systems are.
That (In addition to the ability to receive GPS signals) is what E911 is.
The fact that cell towers are in fixed positions and broadcast with strict timing requirements is why E911 works even when signals from less than 3 GPS satellites are available - the towers themselves are essentially used as "pseudolites" in the position calculations.
In addition, cell tower broadcasts are done with timing requirements nearly as stringent as those used by the GPS system. (In fact, most cell towers have a GPS receiver in them for the sole purpose of providing a time reference.) As a result it's possible to get a semi-decent position fix from cell towers without even relying on signal strength. Combine this with a few GPS signals and you get Augmented GPS, aka E911.
WiFi APs don't even come close to such timing accuracy.
Sub-5-meter accuracy: As another poster pointed out, SA was turned off a while ago. Pretty much any GPS unit will be accurate to within 5 meters if it has a decent signal. With tricks like code smoothing, most errors are probably less than 3-4 meters even for a moving receiver.
Sub-meter accuracy: A little bit of position averaging + basic DGPS makes this easy for a stationary receiver, even when SA was on DGPS could cure the intentionally added errors. Very difficult to use with a moving receiver unless combined with an inertial navigation system. (Rare except in modern airplane navigational systems)
Millimeter accuracy: Also possible before SA was turned off, but required the receiver to be stationary for a long period of time, and required significant postprocessing of the data using a variant of DGPS. It still requires stationary receivers for nonmilitary systems.
About the only thing that can't be done without a method for decrypting the P code is sub-centimeter positioning of a moving object. Even with the P code available it can't be done without combining a high-grade inertial navigation system with the GPS system.
It got high enough to burn up upon reentry, but not high enough to achieve orbit.
That or it's simply not in its intended orbit, in which case reestablishing signal is a matter of finding the thing (which will happen eventually) so that one can figure out which way to point the groundstation antennas.
Search for Troops there and you'll see a link to a torrent for the new movie in addition to the original Troops (the latter of which is a nearly dead torrent)
Still, if the result of un-RARing the file is an.exe when you downloaded video, any moron can tell that something is WRONG.
Such torrents would quickly die from lack of seeders.
So far, very few (if any) BT clients are bundled with spyware. Perhaps if you got them from an untrustworthy mirror, this would be different, but nearly every client is adware/spyware-free if you download it from a reputable source.
With the exception of downloading warez (games/apps), there's almost no way anyone could sneak spyware/adware into a BT download. You just simply can't infect AVI/WMV/MPEG/MP3 files. Probably 50% of BT traffic (or more) consist of media files. Another 30-40% (at least) are Linux ISOs, which are also pretty damn hard to infect with spyware/adware.
Earthlink has broadband services

Zombie Report By ISP

· Score: 2, Informative
Just like AOL, Earthlink has been making a huge push into broadband services.
Remember, traditional AOL service is dialup too? No difference between Earthlink and AOL in this respect. Both are dialup providers that have begun a push into broadband service, and in Earthlink's case, even mobile phone service. (Earthlink is an MVNO that resells Verizon and Sprint service.)
They had the most zombies but a lower rate than others. They spin this as good.
But according to the post, Earthlink (the fourth largest provider) wasn't even in the top 20, implying that their zombie percentage is far lower than AOL's.
The idiots at Novell didn't bother to quality test the sync features of Evolution 2.0 AT ALL.
It's Palm sync features are totally broken. It will always dupe every contact in my Treo 600's contact list, and will also destroy any category info I've set.
Do a bit of research into coding theory - What they're speaking of here is called coding gain.
The idea of coding theory (usually applied to telecommunications, and I'll speak of it as it applies to communicating bits of data here because that's the aspect of it I'm most familiar with) is to introduce predictable redundancy into the data you transmit so that if some of it gets corrupted, you can recover the original message without error.
An example of this is the (23,12) Golay code. For every 12 bits of information you wish to communicate, the Golay code adds an additional 11 parity bits, for a total of 23. Thus, for every information bit you send, you must transmit nearly two actual bits. As a result, your probability of error for an individual bit increases significantly because each transmitted bit contains about half of the energy that your information bit would carry if no coding was used. The Golay code can correct ANY error pattern of up to 3 bits within a 23-bit message. (while an uncoded scheme can't correct any). The end result is that your bit error probability for the coded system will be equivalent to an uncoded system with twice the transmitted power.
I.E. the "bigger" you make your message, the more likely an error is to occur in your message, but you gain the ability to correct for these errors, and the probability of an *uncorrectable* error decreases.
Even flathead screwdrivers can deliver a nasty puncture wound. One of my neighbors needed to get quite a few stitches due to an accident with one. Philips screwdrivers are even more dangerous.
Yeah, many people don't realize there are numerous ways to hide a cell site, especially if there's an existing tall building.
There's a Verizon site on the top of Barton Hall on Cornell's campus, and there's basically no way anyone who doesn't know it's there and is looking for it can see the antennas - They're sector antennas on the sides of a cupola painted the same color as the building. Plus in that particular case they're dwarfed by the amateur radio club's monster HF Yagi.:)
The biggest difference here was in the user interfaces. Given identical user interfaces for transmission, the SMSer would've won for a long transmission, because SMS is FAR faster in terms of a communications system. Once the message is composed, it takes a fraction of a second to send.
If you wish to compare systems with similar channel bandwidth (50 Hz), then the two morse coders would've been totally owned by another pair of hams with laptops running PSK31.
Morse simply defines the on/off pulses that must go out on the airwaves.
How the operator selects those pulses is irrelevant, whether it be a classic straight key, a "bug", or a keyboard connected to a PC running a Morse keyer program.
I haven't watched the video yet, but it sounded like these ops were using "bugs", which are a specific type of two-button keyer. Move the paddle left, and it starts sending out repeated dashes. Move it right, and it starts sending out repeated dots. (I might have left/right switched there, but you get the idea.) It's a two-way switch which can essentially be considered two buttons, but the end result is still morse code.
A 10MP digital camera depends on so many non-camera-specific technologies that such technologies would have been developed with or without resistance from the film camera industry.
The #1 issue being storage - Do you really think digital cameras are solely responsible for modern hard drive and flash memory card capacities? Because without large hard drives and memory cards, a 10MP digital camera could not exist.
If this motor is all it claims to be, it will be excellent for hybrid vehicles. Using a hybrid negates the battery life issue, and there's NOTHING that says that a hybrid can't be designed for performance instead of gas mileage. Using a hybrid technology means you can optimize your engine for pure horsepower and nothing else. No worrying about turbo lag, no need to deal with variable valve timing since the engine will either be on at full speed or completely off. (As opposed to traditional engines where a tradeoff between peak horsepower and overall driveability usually has to be made, unless you use complex workarounds such as variable valve timing and variable nozzle turbochargers.)
