It's just bits and bytes set in a certain way, and they can be changed 
anytime. From a philosophical viewpoint, there's something fundamental 
different between software and a house.
Actually - from any viewpoint, I guess.

red thread is rolling quickly so not to be overlooked: interresting 
toy for cheap: http://www.raspberrypi.org/ARM based 700MHz core 
256MB RAM 100 Mb Lan 2 USB ports, SD card reader  some (not exactly 
stated how many) GPIO, 1W power under full load, Quake3 and HD movie 
playing demonstrated. Linux supported from producer, but architecture 
not restricted to linux only.

could this be the project Carl is working on !? it is an embedded 
linux, its also more TV than computer since it supports only TV outputs. 
 Carl's low memory using Amiga Exec Background would make him a prime 
candidate for working on this project which has to boot Linux and 
allow HD decoding within only 128 MB (os+gpu Shared) RAM .

They're shipping Ubuntu
The movie demos they did so far used their own player thingie. It's 
likely the standard Linux players won't cut it on Ubuntu in the provided 
memory

he was doing .. or did I miss it?

For Open Hardware followers: http://hardware.slashdot.org/story/11/09/19/1835250/Arduino-Goes-ARM
I should be able to port Red on the Arduino Due (32-bit, 50KB of 
RAM) but the still low memory size might limit its usefulness. OTOH, 
Red/System should be able to work full power there. It should be 
fun to write a new OS for this platform using Red/System.

It would be nice to have one of these types of little computers, 
which can shut down to some really low power use state, or even turn 
off, while passing power to something like a wrist watch level tech, 
which can react to some input (a dry contact, or a timer, or a signal 
from the internet in some form).  Very power combination for many 
applications.

That should be doable, with the "wearable" version of Arduino boards 
(the Lilypad): http://www.arduino.cc/en/Main/ArduinoBoardLilyPad


They are also some wrist watch level Arduino-based prototypes (often 
using an OLED display): http://www.google.fr/search?gcx=w&q=wrist+watch+arduino&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&hl=fr&tab=wi&biw=1113&bih=1036


A few more very creative Arduino watches: http://hackaday.com/tag/watch/

There's even one you can already buy: http://www.getinpulse.com

will the ARM arduinos be available in the same form factors as the 
existing ones?

Here's a photo of the ARM-based new Arduino board: http://www.semageek.com/wp-content/uploads/2011/09/ArduinoDue.jpg


I am not sure it will be available in tiny forms like the Lilypad 
or the Nano though.

Arduino is already based on ARM in its NetDuino variant, Netduino 
is also in micro variant (breadboard based).

The theorists who know what that are talking about will have a lot 
of fun with that evidence, Graham.


The rest of us can make things up -- like perhaps neutrinos are the 
only things that actually travel in a straight-line at a quantum 
level; photons take a longer path because they are bouncing around 
a bit.

actually travel in a straight-line

 :-D (Instead of the Relativity theory, you prefer to destroy the 
 Quantum mechanics?)
Or I should ask: Alongside with the Relativity theory you would like 
to destroy the Quantum mechanics as well?

Experimental results have demonstrated that effects due to entanglement 
travel at least thousands of times faster than the speed of light

travel at least thousands of times faster than the speed of light
 - except for the fact, that they actually don't "travel"
GrahamC

No, just teleport!
though if you have entangled pair, and you determine the spin direction 
of one pair, then the spin of the other is then set.  But .. the 
knowledge of the other spin is only known at the site where the first 
determination was made, and that information can not travel to the 
other site faster than light so perhaps the limit applies to that 
information?
Sunanda

Right -- it's similar to Ly Tin Weedle's proposed method of instantaneous 
information transfer by modulated torture of a small monarch:

Sounds pretty interesting, but when will we see commercial deployment? 
Rossi is planning for October, this year, for his process. A Greek 
company is investing 200 million euros in the plant.


An update on the E-CAT: The Greek company that was investing in this 
plant, mysteriously can't pay the money, so the 1 MW plant is now 
supposed to be installed in the US instead.

Here are some pictures of the power plant:

Another test was also conducted a couple of weeks ago, but it, like 
the other tests, did not show anything conclusively that the device 
really worked. It's highly suspicious.

Actually, despite the rift between Rossi and Defkalion, it seems 
that Defkalion is still on track to show their own tech (Rossi derived, 
I guess) in the near term. They just re-opened their forums.
and Rossi's own demo for October is still supposed to happen

Amazon announces crazy Kindle prices and their $199 tablet
AdrianS

it bugs me that they forked Android (based on a version prior to 
2.2) - that's a second strike. The first was that they bought Touchco, 
a very promising tech company which had one of the best and cheapest 
touchscreen implementations ($10/sq ft), good for both stylus and 
fingers. This should have been technology for the masses, not restricted 
to Amazon. Oh well, I guess it's still for the masses if they sell 
enough tablets with that tech, at some point. Forking Android though, 
screw them. With their user base, they have the potential to upset 
the Android cart.

Amazon is cool but they seem to have the MS mentality of ignoring

Looks cool. I'm wondering, why spacecrafts always have a smooth surface. 
Pinguins are known to have very little resistance, when they move 
through water, and they don't have a smooth surface because they 
used to have feathers. Sharks have a rough surface, I guess this 
also mean less resistance, when they move through water. A golf ball 
fly longer with all its little bulges, than if it had a smooth surface. 
Yet spacecrafts have smooth surfaces.

It probably depends on how much is gained by improving airflow around 
the rocket body in relation to reducing its mass.
