In the "graph" picture, it mentions that it's indeterminate that the carbon from the chlorinated carbons could be martian or terrestrial and that further analysis is required.
I thought carbon is carbon. How would you tell if it was from Earth or not? "Made in China" labels on the protons?
I'm sure you know more about this than I do, but I'm struggling to understand how an 89MHz ARM CPU is better suited to realtime operation than a 700MHz ARM CPU. I'm assuming that it's the connectivity (Arduino pin selection vs the Pi GPIO header) that makes the distinction?
There is a difference between embedded and real-time.
A real time system is a system that will guarantee a response within a set time to an event. You don't want commands to a nuke reactor cool down to be delayed a few milliseconds because the linux kernel decides to spend too much time sorting out its memory paging or something. :)
You can get customised versions of the Linux kernel that can be realtime.
But, the arduino would be coded for a specific task, and only that task. You don't expect to run bittorrent in the background. :) Plus, a 89MHz processor would be cheaper than a 700MHz, for a washing-machine control board.
It made me laugh when the Pi's were being bought on ebay for 100+ quid. Nutters! You could've bought a much better platform (beagleboard, pandaboard, cubox, snowball, etc) for not much more with more memory, faster processor (even with hardware floating point!) and more on-board peripherals.
As for the arduino vs pi argument, I definitely agree with the sentiment that they're different tools for different jobs.
Depending on the project, you could use the Pi as the main processor with the arduino (or the leaflabs maple, or even a bare-bones ATmega with arduino bootloader) as an "intelligent" I/O daughter board powered and communicated via the Pi's USB host.
There will always be needs for HDDs.
Just because mobile applications are going cloudy, and maybe documents too, don't forget that there are other uses for HDDs.
More and more TVs and STBs (Freesat+, Sky+, Virgin with TiVo, etc) are being built with internal hard-drives for recording purposes.... and I'm guessing a lot more people have TVs than PCs...
it's probably a case of:-
doctor: "subject has high pulse after playing the game. as expected, due to adreneline, etc"
reporter: "pulse is high. gotcha. what would be the effects of resting pulse was that high, normally?"
doctor: "not good."
reporter, writing headline: "playing 3DS makes your heart go boom!"
