In 2018, why are credit card numbers still a thing? A "secret" number printed on the front of your card, typically in raised, bold characters. And we wonder why these are stolen? Hand your card to a minimum wage worker who takes it away from you temporarily -- and we accept this?! The only reason why this irresponsible negligence is still perpetrated is because neither the banks nor the processors lose from these thefts. They MAKE money on chargebacks. Virtually all the cost is borne by the merchants. Even consumers are largely protected. It's a horrible system but the organizations with the power to change it, are not incentivized to change it.
He conclusively proves that the FCC doesn't understand the Internet; then he concludes, therefore, the FCC should be the ones to regulate it. I'm not sure I follow that.
They do liveness detection with iris (except in the movies) so quality iris biometric systems are _not_ fooled by a picture. This doesn't seem like a possible countermeasure with an inanimate trinket.
The article gives a False Reject Rate of 4.25%, which I thought was annoyingly high. It seems they tuned their threshold to push down the false accept rate to 0.02% and just accepted the annoying FRR.
All digital transmit is easy and has been done with FSK, BPSK, OOK, and numerous other K's by many people lots of different ways. We do this as a class exercise at 228 MHz using a Digilent FPGA board (Nestor, J. A., & Nadovich, C. (2009). An FPGA-based wireless network capstone project. In 2009 IEEE International Conference on Microelectronic Systems Education, MSE 2009 (pp. 53–56).)
Much more difficult is all digital _receive_ as you need to conquor the selectivity and sensitivity problems. It's hard to avoid using at least a balanced mixer
in the receiver.
Power radiated from an antenna propagates outward in a mostly spherical distribution (not accounting for directivity, ducting, etc..) and a sphere has an area of 4 pi r^2. The amount of power received is proportional to the area of the receiving antenna. You will find, if you do the simple math, that r^2 get big real fast and that any practical receiving antenna at any significant distance subtends only a tiny fraction of that sphere's total area and thus only receives a tiny fraction of the radiated power.
Who would want a small company to win a part of the spectrum? By definition, they wouldn't be able to use it universally for all Americans.
"What's good for General Motors is good for the country."
I can think of zillions of product ideas that a small company could develop and market that require spectrum allocation. And small companies are where true innovation comes from. Innovation breeds competition and competition benefits everyone. On the other hand, what
benefits big companies largely benefits only the stockholders in those big companies.
Personally, I think the concept of owning spectrum is bankrupt. It's an early 20th century holdover from days when frequency multiplexing was the only technology available. The FCC should move to a different model where no one monopolistic entity controls the airwaves.
What, has it been like 5 years this has been happening and suddenly it's news? Credit cards authentication is a total joke. The security of credit cards is based on chargebacks to the merchant, placing the burden of fraud prevention almost entirely on the merchant. Banks and processors profit on fraud because of chargeback policy, and consumers are protected by law.
When the merchant is a charity, none of this changes by magic. The charity/merchant is still responsible for dealing with fraud. It's ridiculously naive, and arguably irresponsible, for a charity to accept unverified credit card donations.
IMHO, a real e-cash system like e-gold or moneybookers should be usedq, or better yet as distributed system with no central database, but the governments that print fiat currency don't want to give up their monopoly and use excuses like "think of the children, child porn, terrorism, etc..." to thwart the development of viable e-cash alternatives by imposing arbitrary requirements on them, or charging them with violations of laws that do not apply to fiat cash, etc....
> This case though should still be thrown out. The DMCA only prevents circumvention of effective controls.
Effectiveness is not a criteria. CSS is not effective for thwarting copying, yet it seems to be protected by the DMCA.
There's a subtle validity to this claim. I hope they sue, and win. That would surely illustrate the surrealistic absurdity that copyright has become.
People shouldn't donate blood now. Do you think the artificial blood inventors and manufacturers will donate their technology? Do doctors donate their time? Do nurses? Do the people who process blood from blood donations donate their time? Health care is a giant commercial industry. Asking people to donate blood is like asking the Saudis to donate oil.
Switched a year ago. Best decision I ever made, computing wise. I now type faster than I ever did qwerty. I touch type with no bad habits. My wrist pain is gone. Total cost: about one month of agony.
I once threw a box of 120 Gig tapes into a dumpster. I think there were about 200 tapes in the box. I admit the distance wasn't far, but the burst rate was 24 TBytes/sec.
It would seem to me that shortly after some big corporation tries to segregate the Net, if there is any marginal advantage to the bandwidth carrying their segregated service, somebody will devise a way to tunnel other services through the "premium" bandwidth. If I can send you bits, I can code my data into those bits, steganographically if necessary, but there's no way the channel can stop me from sending whatever I want.
So I say, bring it on. We'll have fun writing ironic tools like IPOV -- IP tunneling over Voice Channels -- betcha we can send up to 56K bits/sec on a 3 kHz analog voice link.

Cool. Now we'll all have a way to prove to each other how much media we've pirated.

"If self-driving cars rack up fewer pedestrian deaths per mile driven than human drivers, that's the critical metric."
Only if they are judged relative to human drivers. If they are judged in product liability terms, the metric is lawsuit damages per mile driven.
