We must have had RFID-enabled employee badges/pass cards on steroids then. [...] You could just barely avoid having the doors along a hallway unlock as you passed if you walked along the far wall of the hallway, which would've been about 6 feet.
There are older technologies which used large (inches in diameter and tens or hundreds of windings; these are large compared to the millimeter-sized RFID tags being talked about today) inductive coils to both power and communicate with a chip embedded in a card. I had one to enter an office building at a startup in the 90s.
The technology and protocols used are quite different between the two. With the old ones, you couldn't easily have multiple tags present -- the reader would get hopelessly confused trying to decode the interfering signals. The new inventory tracking RFID tags, however, rely on the reader to interrogate tags; it only looks for an "I'm here" signal from any tag as it progressively decodes more bits. There are some interesting exploits for this weakness; my favorite is Rivest's technique which sends the "I'm here" signal for every possible pattern requested by the reader, causing it try to interrogate the entire id space -- a bit like trying to brute force an encryption algorithm.
The FOSSology source code is licensed under GPLv2 Does it just say GPLv2 in their license file, or did they properly analyze the source to determine it was GPLv2?
Ah, but the mass of the plane also increases as speed increases. At a mere 0.99999999999999999999c, the relativistic mass of a 300,000 kg 747-400 exceeds the mass of the earth. So the plane doesn't crash into earth; earth crashes into the plane.
Don't OEM's actually use the machines they send out?
Not really. It's like junk mail, inserts in newspapers, and "special advertising sections" in magazines. They're not putting these there because it benefits the customer; they're in there because the companies are getting paid a ton of money to do so.
The post modern struggles of the common man are evident in this minimalist piece. The faint echoes impute a sense of desertion, a lone voice in an empty chasm. Midway through the piece, the listener is invited to shudder at the conflicting emotions.
However, the ending disappoints with flat tonality as the vocalist almost spits out the "-oop." If this piece were a wine, it would have fruity though not overpowering hints of apple but an unpleasant, almost vinegary finish.
This is a performance which should be heard at least once by listeners who enjoy discovering new, novel challenges in auditory stimulation. However, it's not destined for the classics. Future students in the field will encounter this work as a footnote in the progress of informational tones, but it is otherwise a forgettable piece.
Basically, your server can go down at any time and any data on it will be unrecoverable. Precious data must be stored off the EC2 instance (e.g., on S3).
The implication is that you need to architect your application with this in mind. It has to be deployable and bootstrappable from a master image (typically the EC2 machine image). It either has to be stateless (generally preferred) or be able to recreate its state upon startup and periodically checkpoint its state while running. This is generally true whenever you're working on a large, distributed application and are properly treating your application servers as substitutable commodity machines. However, many people take shortcuts and depend on the reliability of the running hardware; EC2 is can be very unforgiving if you do this.
Akamai is a different beast altogether -- they're not a generic computing center, but a finely-tuned cache that gets your (mostly static) data as close to the user as possible. In fact, Amazon uses Akamai (PDF press release) to host some of their content.
The difference between Sun's Grid Computing and EC2 is that EC2 is connected to the net. This doesn't mean you can't run huge batch jobs on EC2; however, there's a lot more you can put on there (read: hosting for the Web 2.0 company you've founded in your garage, mom's basement,...). However, EC2 doesn't give you a load balancer (yet); getting the traffic from www.your-spiffy-domain.com to the EC2 instances is still your problem.
S3 is, IMHO, the more interesting of the technologies today. Buying storage capacity these days is cheap; maintaining it, however, is as expensive as ever (perhaps moreso as clients expect higher availability, geographic distribution to minimize risk, etc.). And, if I'm too small for Akamai yet need to host some static content over a fatter pipe than I have, I can even expose it to the rest of the world through the REST interface./p.
I find it more dismaying that an otherwise seemingly adult and mature article writer feels such an urge to childishly emphasize blame. I take it you haven't been in corporate circles...
If blame is so important, can't you people at least blame the engineers and not the nationality? Or at least blame Canada...
The article doesn't state which country (or countries) this was patented in. Keep in mind that the Berne Convention applies to copyrights, not patents -- a given patent applies only in the country in which the patent was granted (unless two or more countries have a reciprocity treaty in force).
Therefore, if CSIRO submitted the patent to Australia's patent office only, infringing equipment can be sold everywhere except Australia. More likely, the companies involved could negotiate a lower price for the license.
Second, it is essential to select the proper filter for your coffee maker. It is generally acknowledged that a metal type filter is far superior to any other types available, because this type of filter will not impart any strange flavors into your coffee. These metal types are often gold colored, but silver colored ones can be found too. It is also generally acknowledged that using a paper filter yields a superior pot of coffee, because metal filters tend to let sediment pass into the coffee. Above all, it is most important to remember make sure you're actually using a filter, or else you might end up with a mug full of coffee grounds and dark colored water.
This goes beyond neural networks. This is actually simulating the behavior of physical neurons, but in silicon. Physical nerve cells have extremely nonlinear behavior in various regimes (hyperpolarization, depolarization, etc.). To what extent is this is necessary for complex behavior exhibited by animals? Frankly, we don't know. This research will hopefully answer some questions (and raise a host of others in the process).
Neural networks are a simplification of the actual electrical response of a neuron. Or, to put it another way, we "dumb down" neural networks to the point where we can grasp how the math involved in backpropagation, etc., work out. This isn't a criticism -- in fact, it's a useful abstraction -- but we've only scratched the surface of neural networks in this manner.
Boahen is a graduate out of Carver Mead's lab at Caltech. Carver spent a lot of time trying to replicate the behavior of neurons, the cochlea, and the retina in silicon. If you're an electrical engineer, take a look at his (rather readable) book, Analog VLSI and Neural Systems.

Please. In 2038, black holes eating away at the earth will be the least of our concerns.

No, no... the bucket is the restroom. We're all about breaking down walls -- and stalls are walls, so...

I think you're confusing Linux with NetBSD.

There's a saying where I live that goes... "You just need to sample a single grain of rice to judge an entire pot..."
Here, a cereal analogy might be more applicable: You just need to sample a single flake to judge the entire bowl.
VA Software owns Slashdot: [...] Ergo, VA Software is a media company.
Media company? I always figured their specialty was data storage and online backups. How else can you explain the nice stream of duplicate articles?
Oefelein told investigators he and Nowak both served on the bicycling team at NASA... Man, I know NASA is strapped for cash, but bicycles?
