Comment Re:Nope, and missing the point (Score 2) 75

Bucky Fuller is an idiot.There is no way a gallon of gasoline could be valued at $1 million. You can sell something only at the price someone is willing to buy it. It has nothing to do with the production costs. However, to make a profit, your production cost must be lower than your selling cost. There is no one to pay for the time and energy it costs to create petroleum, no one can pretend to ask someone to pay that cost.

Comment Re: Pierson's Puppeteers (Score 3, Informative) 695

Focussing on a single argument, even if I could argue on others:

2) crops grow better

Most food crops are harvested between 30th and 50th latitude too. Around the 23th latitude (both north and south) you have either large deserts, where nothing grows, or you have the rain forests, which don't have any meaningful soils to put food crops on.

Pretty much naive picture here. First of all, this should be weighted by the amount of land available for the considered latitudes. Second, desertification has many causes which are not related to the temperature itself. For exemple, the Himalayas prevent clouds from the Indian Ocean to reach Tibet on the other side creating large dry areas and deserts. To summarize, your arguments aren't any better than the points you are trying to defeat.

Comment Bare bones OS (Score 1) 134

The Pi is really nice for "soft" realtime projects - but running a full OS like Linux means that you can't ever get really solid realtime performance.

The hardware is now down cheap enough to replace Arduino's in the role of "bare to the metal" devices - and it sure would be nice not to have to have two families of boards in my hardware supplies box.

So how about a bare-to-the-metal OS - with nothing beyond the ability to download an executable and boot/run it and all of the hardware exposed...or perhaps some means to lock away one CPU core to run a hard-realtime task while Linux runs on the other(s)?

Comment Re:coders are not programmers (Score 1) 82

Yes because 'programmers' never make mistakes, right?

These aren't mistakes, they are encoding the messages rather than encrypting them using a public encoding scheme (anyway, a private encoding scheme wouldn't be better). So, they did actually think about the security, but due to incompetence in the field, they pick an encoding scheme to secure the communication. That's not the first time I have seen such a thing. Some coders believe because they cannot read the message it is encrypted.

Comment Re:Any military use? (Score 1) 102

That's why this satellite won't deliver its promises at my opinion. I doubt it is possible to maintain decent quantum characteristics to perform quantum cryptography in this environment. They will increase the intensity of the laser beam to decrease the error rate which would be otherwise unacceptable. This will open the channel to side attacks.

Comment RealSense == 3D camera. (Score 2) 55

At first sight, it looks like this is a horribly overpriced tiny-Linux gizmo - but what I think people here are missing is the important fact that it includes an integrated RealSense 3D camera...over 300 bucks for a $10 computer is a lot - but the RealSense 3D camera was selling for over $100 a few months ago - and that was a gigantic thing compared to this.

So, while I think they should be selling this for $50 to get more people interested in using it - I don't think it's surprising that they're asking so much as a "dev kit". The original RealSense dev kit (just the camera) was (IIRC) $200 - but included support from Intel engineers for serious developers.
