Actually... Palm took to another level - the apps were only ever in ram, and often their working space was allocated as part of application installation. (Because these devices only had ram - no backing store, like flash - installation was the same as loading.) Yes, battery failure meant you lost all your RAM, but typically the ram was kept alive even if the batteries didn't have enough juice to power the CPU. And there was a capacitor that gave you time to switch batteries.

Air gap... like Bluetooth?

I know what the term means, but heat is just another type of EM radiation (infra-red) that doesn't have dedicated communication hardware. The accomplishment is neat, but not useful.

As a counter-example, the paper on reading monitors from their diffuse reflected luminance is actually useful. You get a high-bandwith, air-gapped eavesdropping method. This communication by heat is more likely to be detected (as a problem, not necessarily as communication) than a steganographic (thank you) communication channel using more common EM radiation.

I'm not saying it's not 'neat'. It's just not neat and useful.

What is perhaps a bit of irony of history, even for humans a lookup table is faster and more precise than manually calculating it via formula. That is why they published books of logarithms. Using interpolation you can even stretch out the precision to several more digits. With a table of values in memory you can also narrow down the inputs to Newton's method and calculate any differentiable function very quickly to an arbitrary precision. With some functions the linear approximation is so close that you can reduce it in just a few cycles.

Even in most trigonometric functions there is a simple table upon which the angle addition formulas are used to get the other values[an old example].

Given the size of most operating systems, where 8k of ram is hardly noticed (most gifs are larger than this), I am actually quite surprised that the lookup table method is not more used. It would seem one of the first things to put in cache on your ALU.

that is an inevitable consequence of any p2p system, simply because the participants are the network

That is not true; see e.g.:

http://eprint.iacr.org/2012/441

Here is a layman's translation:

• It is a peer-to-peer system for computing a function over inputs from N parties
• The privacy of each party's input is protected i.e. no party will learn any other party's input beyond what the function's output reveals
• The privacy of each party's output is protect in the same fashion as the input
• The outputs are guaranteed to be correct if the protocol terminates (an attacker might just stop the protocol early, in which case there is no output)
• All of the above holds if the attacker can take over a majority of the participants (e.g. like the attack I described above)
• All of the above holds if the attacker can choose which parties to corrupt after observing some part of the protocol

In other words, this is a system that protects against an even more sophisticated version of the attack I described above.

Okay, how could it be improved?

Drop the idea of not having any banks, and then create the sort of system described in this line of research:

Kind of sad performance but maybe someone can fix it.

Don't you feel someone has read too many gibson's novells ???
If that hell becomes reality, will he be seen as the Jules Vernes of the 21th century?

"Power, in Case's world, meant corporate power. The zaibatsus, the multinationals that shaped the course of human history, had transcended old barriers. Viewed as organisms, they had attained a kind of immortality. You couldn't kill a zaibatsu by assassinating a dozen key executives; there were others waiting to step up the ladder, assume the vacated position, access the vast banks of corporate memory."

Jules Vernes described a world where science helped men to free themselves, not to build new ways of stealing freedom from each others.

- NeHe productions has over 20 OpenGL tutorials online, starting at the absolute beginning.
- The OpenGL Challenge is a weekly OpenGL compo that requires entries to be opensource. Has some *really* cool stuff.
- Romka Graphics has loads of misc OpenGL stuff, worth checking out.
- The OpenGL FAQ and troubleshooting guide is another overload in OpenGL-related material.

And besides that, I also run my own daily news site located at www.demoscene.org and is all about multimedia development, so a couple of OpenGL-related links turn up every week. Hope this helps...
