I am aware of 3 or 4 car models already with HUDs, including the Camaro. Honda Civic's in the last few years have a big digital speed display above the steering wheel. It is much easier to read and I am always bothered when driving another car with a regular speedometer...
I have also seen speed HUDs for skiers before with special glasses, aren't there any already for bikes?
For CS, there are a number of programming goals that can be graded automatically, and that is used in several courses - both in Udacity, Coursera and the ML course mentioned before.
You just have to make the student respond to an interface - i.e.: setting an object or variable to the answers or outputting them in a particular way.
For example, in the NLP course the first exercise involved using regular expressions to extract e-mails from web pages. You had some starter source code and a set of pages included with the exercise. You just fill in your code, and run it locally to test it against the local set. Then you submit your code, and the grading software runs it against another set of pages, from where it gets your score for true positives, false positives, and misses (it also used the set you already have, but that had a lower percentage, I think).
It is not perfect (you can't easily measure the cleverness of the answer or the quality of the code, just how well it works), but it is very nearly free.
Given the average quality of the CS courses out there, I think that this system is very acceptable, and bound to get better with time.
I have seen them a few years before that on a Charles Sheffield (?) short story in Analog or Asimov (can't find a reference, sorry).
I remember it being mentioned that the glasses cost as much as car. Nice to see that we have surpassed SF in this way again.
Third, I like how the homework questions for the other two are presented in a normal web form format (whereas the AI class "homeworks" require you to watch a video of the instructor reading the questions) and also allow multiple submissions.
I am taking the two AI classes, and I find that pretty annoying too. It also takes a lot more time than just reading the notes, and even worse - all the time they have to post corrections and clarification in text below the video, whereas they would just edit the question if it was in text format.
In the AI class, both presenters are making video of paper they're writing onto, and constantly waving a pen above the page in the video, making it tricky to find a place the video can be stopped. The videos are embedded YouTube videos, and it takes about 2 seconds for the video to actually stop once the pause button has been pressed, and once it pauses the controls come up and cover up the bottom part of the video.
While I still agree that PDF notes would be much better, any screenshot program that freezes the screen would solve most of your problem. I use Ashampoo Snap, and I still have to wait for the pen to be in a place that doesn't block anything, but it freezes the screen whenever I press the shortcut (then I can clip just what I want).
The database contained "information including user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information."
There is no evidence of main steam accounts being compromised and forced password changes are being used only on forum accounts.

Might be for Dow, but looking for a couple of minutes on Google shows several companies that sell them.
i.e.: a blog from 2005/2006 and he had solar shingles back then.
It is available as an e-book here . US$30.59
Another e-book on the subject (I've started reading it and liked it, but didn't get around to finishing it yet) is Hello Android.
One thing I like about The Pragmatic Bookshelf is that they deliver directly to your Kindle. They are also DRM-free (Packt says they are too).
I'd think it was a bit more of a marketing thing than a research thing...
The largest bank in Brazil has been doing this for years - with a small Java program that at least says it's checking your computer (and takes only a few seconds). I've never tried denying it, but I'm pretty sure you just can't access their online banking without allowing it to run.
I have never heard of anyone complaining about it.
