It's not a radar but a LIDAR, basically a scanning laser range finder. It's not only ugly, but ruins the aerodynamics, and is very sensitive equipment, prone to failure. Elon bets on software getting good enough in the future to not need LIDAR.
I was thinking the samen thing. The transient of the pedal command would however be very informative. If the sensor value increased in a way consistent with someone pressing or slamming the accelerator, it would point to a user error. If the value increases to 100% within one sample time, that would point to a sofware or electronics error. At least, if the sample rate is high enough...
First, this allows you to see how the road curves very far ahead, and without using the high beams. It works much better then reflective paint.
Second, this is not painted on the road, it is a special strip that is embedded in the road surface. They can also send a tiny bit of current through it to intensify the glow, which is especially useful in winters. It essentially cuts the energy requirement with a factor of a few million (a number which I just made up).
Thanks, that is a nice one! One thing still bothers me with this: What if the second envelope had equal content to the first the whole time, but it just flips depending on the way you slice it open? That way, you can never prove that there is some entanglement, the association was made when the envelopes were created, and the flip (or not) to opposite is made only with local information.
This is something I truly do not understand. Americans should be extremely proud of Tesla Motors! An american company launches their first fully in-house developed electric car, almost out of nothing, and completely blows away anything that is available anywhere in the world. Including decades old multi-billion dollar companies in Europe and Japan. This car is not cheap, but it is exclusive, well built, comfortable, reliable, has good range, incredible performance, is innovative and almost legacy-free. And very importantly (and surprisingly for an american car if I may say so) actually looks very good! Furthermore, the company takes initiative to create a very useful charging network, and has amazing customer service. Americans, embrace Tesla Motors please!!
Compared to many of its competitors, Microsoft is know at least for their perseverance. When they start something, you don't have to be afraid that they will drop it like a brick the next year. That, at least for many people I know, is a large factor in deciding whether to join in or not. Compare this to Google, however great their "free" services, that drops products whenever they feel like it. I myself was pissed off to no end after Google discontinued Reader, iGoogle, Latitude, and crippled the Maps app on Android.
Exactly! Whenever I see claims that life started on Mars (or was brought here on meteors) I wonder why there is even a need for those hypotheses. You need pretty strong evidence that life COULDN'T have started on earth to resort to such a much less likely theory...
You just perfectly worded how I feel about it! For me it started with iGoogle (for which I still haven't found a replacement), but that was just (for me at least) a single incident This Reader move makes it a clear trend. It doesn't help that apps I paid for rely on this service.
Well technically H2/LOX got us to the moon, the RP1/LOX got us out of the atmosphere... And incidentally, using LOX is a lot less primitive than using RFNA.

Wouldn't it be great if he came out in the end saying "what the f*ck were you thinking, agreeing with all that nonsense I was spewing???"
Thank you, Faith in slashdot community restored.
Mod parent up, completely agree! (MSc Aerospace Engineering)
Thank you for this!
Especially the Dutch East India Company...

:-D Where are the mod points when you need them?
Funny use of the word "snaps", considering the exposure time of 103 hours (TFA). But I guess, on a cosmological scale...
:-D
GPS satellites are not in LEO, but not quite GEO either...
and they're geostationary (or at least some of them are)
Are you sure?
Thanks, that is a nice one!

Well actually it's not in the focal plane, that would be the retina, but your point is valid!

Actually, the battery packs are already liquid-cooled.
I always prefer removing heaviness instead of adding lightness...

Made my day..
Where are modpoints when you need them?
Came here to post exactly this :-D
Mod up please!
Interesting presentation. The graphs could use some legends, but the message is sorta clear...
