I hear a lot of references to the 'modem' when talking about the tower. It gets infuriating when talking to people with an actual modem/router problem because they have no idea what's going on.
Not to mention safety. The Civic comes with what, six air bags? Not to mention more technology put into other safety areas, such as crumple zones.
I used to drive a '95 Ford Aspire. It regularly got over 40 mpg, but I was always so scared of a side collision. The doors are so thin, I think I could've punched right through them with my fist.
Not to mention that having 63 hp, the car could barely get out of its own way, even if it did weigh only 2000 pounds.
I really feel the need to reply to this. If you read the article, you'll notice that/all/ cars are getting their EPA ratings adjusted, not just hybrids. They use the same rating procedures on all cars. There isn't a special way of rating hybrids that differs from regular IC cars.
I want to share a bit with my personal embedded software development experience.
Disclaimer: At work I develop for VxWorks (5.4 through 6.2), RTEMS, Linux and OS X. VxWorks and RTEMS for real time work and Linux and OS X for testing.
I would not go with VxWorks if you don't want to pay a ton of money. Also, with VxWorks, the support is not good at all. The support website is written horribly and is very slow. It takes a long time to get a patch for anything wrong in VxWorks, and the next iterations don't include the patch.
Besides, right now VxWorks is going through a transitional phase where it is migrating away from its traditional schema and moving more toward a Linux implementation. Wind River even has a separate Linux OS which they market now too.
Another thing is: do you really have a hard real-time requirement? If the product doesn't need to have an answer in X milliseconds, and just needs to be fast, then that isn't real time, and you can save yourself a lot of money.
As far as other vendors go: LynuxWorks has a real time OS called LynxOS. It is extremely compatible with Linux binaries. They also have a linux product called BlueCat Linux that is even cheaper. They even have a DO-178B certifiable version, if you really need it.
Nucleus also produces a similar OS.
RTEMS is an open source real time OS. I'm guessing you would have no interest in it.
Even though they add a little bit more compatibility each iteration, VxWorks is still the least posix compliant OS listed.
But, please, watch what you say. The only reason we use VxWorks around here is because people here are resistant to change. If you have to start out on something from scratch, don't make it VxWorks.
PS: All of the above are my own thoughts and do not necessarily represent anyone else's views, including my employer.
The software that I am specifically working on is called the OS Abstraction Layer (OSAL). If you code to its API, it will allow you to run code on a VxWorks, RTEMS, Linux, or Mac OS X system. It was designed for embedded flight software use. There will be a new version out in a few months that will employ memory protection. Believe it or not, but memory protection for flight systems has been very hard to do in the past.
This because the manufacturer wants it this way. It gives them more brand recognition, so the next time you see something by that manufacturer, it will force you to think of your program. Note that it is also listed this way in the explorer window view.
The thinksecret article states that the content will never actually reside on the user's hard drive, instead it will be on their iDisk.
Is it just me, or does that suck?
You have to have a.Mac account, and there is not going to be an easy way to burn to a disk.
I was looking forward to this announcement, but now I'm not so sure.

Don't talk about the Mini Coopers Like that!

They do have technical programs such as Electrical Engineering, Mechanical Engineering, Computer Science, etc.

I'm working on some opensource software released under the NOSA license.
The general opensource website for GSFC is http://opensource.gsfc.nasa.gov/

The article is a bit thin, but it raises an excellent point.
Does this mean you actually RTFA?

... and then have the link point to a random article!!!
It's because when they cross the finish line last, all the spectators forgot about the race (and the winners) and think its an entirely different one.
How is this new, my {Unix| Mac| Linux} system has done this for years...
Ok, I don't want to hear any more about it.
Obviously the submitter didn't RTFA, so here are some real links: Here Here and here
