Actualy, there are smart RFID cards. If you check out the HID iClass cards which are read/write and offer encription and mutual authentication. I would hope that MC plans on using something like this.

I'm sure they're going to use smart RFID cards. They make dumb RFID cards and tags that just spit out their number and smart ones that essentially have the same chip that's in your Amex Blue or DirecTV receiver system card but connected to and antenna coil instead of gold contacts. They have enough processor power to run challenge response encryption.
Unless MC is massively stupid, these cards should be more secure than the unencrypted magstrip.
No... just because their passivly powered dosen't mean they can't process data, there are dumb and smart prox cards. A smart prox card has RAM and a processor insted of just ROM, and the processor is powered off of the magnetic field the antenna picks up. Here's an example of a smart prox card:
hID iClass
I allways go ahead and swipe my card and enter my pin before the cashier is done scanning my stuff, this way all I have to do is hit "yes" once their done, so this takes like.5 seconds which I would say is even more efficent than cash.
I just had a cashier at Burger King use the magic pen on my $10 bill. I just kinda looked at her like "are you crazy". It's sad now wheter it cash or credit people allways think your trying to screw them.
I'll go against the grain and agree with you... I'd rather see the intro courses taught in a high level language so the students can focus on the algorithms presented rather than getting bogged down with difficult to read assembly code. Getting to know the algorithms and theory is why we call it a science instead of ITT Tech.
I think it's better to teach assembly along with Computer Design so you can get a feel for what exactly the assembly code is doing. I loved the exercises where you converted a command to binary, then followed the 1 and 0's through the processor.
Plus if you want a weed out class try Functional Languages. Ick.
The reason Hazlett suggests that we switch completely away from RF television is the fact that the spectrum is being used extremely inefficiently (and always has been). For example we simply gave broadcast stations the HD spectrum for free. The process by which the stations got their original VHF frequencies was even less equitable. The best way to go about selling spectrum is to have an auction and sell it to the highest bidder that will be able to make the most efficient use of the space.
The biggest argument against abandoning RF TV is what about the people who can't afford cable or satellite, but Hazlett found that the efficiency lost by allocation the spectrum in the current system is in the billions, and there would be enough money from the auction of the spectrum (and from more efficient use of it) that we could subsidize those who can't afford cable for the next 50 years with plenty left over.
My university has experimented with teaching classes only online, or online except for the final an midterm. But I don't think you get everthing out of a class from a book that you do from a lecture where you can get imediate feedback and watch the steps layed out on the board step by step (I don't like powerpoint lectures for this reason). For our Data Abstraction course (3rd level programing course teaching templates, inheritance, and virtual object, stuff like that) I ended up in the classroom section and most of my friends ended up in the online course that they fould about the first day they showed up. Most of them aggred that I got more out of the course at the end of it than they did and it only works if you want to be lazy.
On the other side a lot of classroom classes might as well be online, like my Statistics course, homework was 10% of the grade, no atandance mandatory, and he spent half of the classes trying to figure out how to do one problem on the computer and never suceeding. I know for a fact he didn't grade the final project or the final. He just gave everyone a B. I might as well have goten that experience online and slept another hour every morning till my next class.
Even without TAs a lot of professors just don't care, expecialy about 100 level courses.
I wonder if a tablet PC, one of the models with a keyboard, would help. Type the notes and then when you get to a diagram just sketch it in. I have no experence with them so I can't say if there really all there cracked up to be.
As for me I take paper and pen notes (if you can manage not to lose one, buy a nice pen), and write asignments and meetings down in a Palm III I bought freshman year. Back in the room I have a Windows PC for games and Word, and a headless Pentium 200Mhz Linux box as a file server for music and movies and writing all of my delicious Perl programs.
Having good networking software set up can really save you in a jam, install VNC on all of you computers and put a copy of the client program on a network share you can get to. If you set up properly secured network shares you can get to your files from any machine on campus so if you forget to bring you paper just print it out in a lab. Also if you can find a copy of Exceed (a rootless X server for windows) you can save your self tons of trips to the CS department labs.
I find most profesors don't care about laptops, but a lot of CS professors (the kind that talk about punchcards) don't like you touching computers in the lab classrooms. If you bring your own they don't care though. As long as you tell them "I'm taking my notes on the computer" they don't mind.
Just because SBC operates as a monopoly in many local phone markets does not make the entire firm a monopoly. If it acquired DirecTV it would defiantly have to be a competitive firm as it entered the Cable/Satellite market.
The real benefit I see to SBC in this is that they want to encourage people to have satellite tv since satellite TV subscribers usually have DSL and not cable modems. They may try and cut you some deal if you sign up for both, a "switch away from your cable company" kind of deal.
Another weird side not is that I've seen in Fort Worth where SBC provides "cable" service to apartment complexes but their "cable boxes" are really DirecTV receivers and they just have one dish for the entire complex (or area, I'm not sure) and split the signal from it up to all of the apartments.
I wouldn't go back to coins any time soon since they have phased out tokens in an effort to force people over to EZ-TAG. The system seems to produce much more reliable data since you can get segment times rather than times at a point. For instance if you put a counter-type reader inbetween an off ramp and on ramp you would read people going much faster than the average. Only bad part of the system is the off chance that no one with an EZ-TAG is going through a segment at a given time, but that never happens during heavy trafic times (All the time in Houston) since everyone has the tags.
As for the "creepyness" of the system I wouldn't worry about tickets any time soon since hundreads of people drive through the high-speed EZ-TAG lanes on the tollways without a tag and the Tollroad authority never bothers to try and send them tickets.
I first found this website from a link on the website where you download Kazaa Lite, Kazaa with all the ad-ware and banners taken out. I think it's hilarious that a site that provides software with the ads hacked out thinks people who block pop-ups are stealing.
