And I care about the deposit of no less than a milliwatt of heat into my brain why?
A miliwatt of heating is probably not a big deal, but that was not the point of my post. I was pointing out that there are effects to consider other that direct ionization when determining if there is a biological effect from EM radiation at any frequency.
Anyone worried about radio waves causing cancer can try to make that theory work. There is a huge barrier, however, in the form of a very very small number: Planck's Constant. Planck's constant = 6.626068 × 10-34 m2 kg/S. It's that 10**-34 that makes it difficult for low-energy electromagetism like wireless transmissions to interact with chemical reactions. Thirty-four zeros is a LOT of zeros after the decimal point.
Unfortunately that completely ignores the issue of thermal effects. As an extreme case try the same calculation for a microwave oven. Chemical bonds in food are affected, but due to heating rather than ionization.
I still use WiFi however as the power levels are a lot lower than an oven.
There are some programmable mixed signal devices avaliable now. Off the top of my head I can think of the PSoC Mixed-Signal Array from Cypress. I'm sure there are others that could be found with some searching.
As a long-time Mac user (with Macs at work) I am more interested in learning what doesn't work on the new Intel Macs than what does.
Here is the compatibility report from MacInTouch. They have complied a quite a bit of reader feedback. There is also a report on Rosetta compatibility.
These form a ball of plasma about 300 times hotter than the surface of the Sun.
According to The Physics Factbook the temperature of the surface of the sun is approximately 6000 C. (I am assuming that it is the photosphere temperature that is ment here.) A temperature 300 times higher would be about 1.8 million C which is an order of magnitude less than the temperature at the center of the sun (~15 million C). I would have thought that these collions would have resulted in temperatures much higher than that.
Does anyone have a better reference for the effective temperature involved?
I look forward to finding out that the Greek Gods were aliens with advanced Quantum Technology (read Ilium by Dan Simmons for that interesting diversion) Actually, isn't there a Star Trek ep based off this?
"Most people assume that the largely detached attitude of Neo is due purely to the inability of Reeves as an actor to emote. What they don't realise however, is that said lack of emoting for the most part is an integral part of the character.
Here I always thought that the inability of Reeves, as an actor, to emote was written into the character after the fact.
How about a database as the interface to a file system? For example music files could be just as easily view by heirarchy, artist, album, date, composer/writer, project they are part of, etc.
How can I write portable versions of Mac OS X apps when the Cocoa API doesn't exist outside of Mac OS X (don't tell me about YellowBox or what-have-you) and the language Objective C isn't supported outside of Mac OS X (Apple is killing off Cocoa's Java support)? Oh, and the Carbon API doesn't exist outside of Mac OS X either (but at least it uses a widely supported language). You mentioned a software company in the Northwest US, but what about the one in Cupertino? Apps written to their platform are no more portable than Windows apps.
The Cocoa API is semi-complete as part of GNUstep. GCC has built-in support for Objective-C.
As far a Carbon is concerned, for some time now I have been interested in statring a project to re-implement that API in a more open manner so that you could use the Carbon API under GNU/Linux or some other operating system. I just haven't had the time to give it much effort.
Besides that, apps that aren't able to take advantave of the underlying platform's unique features aren't sellable.
On this point I agree 100%. Most "portable" applications are lowest common denominator and support only the small subset of functionallity that is avaliable on all of the platforms and this makes for what is often an unpleasant experience.
Ok, so are these gravitational "waves" real or just a construct to explain gravity?
Essentially the trigger for this question is the whole sound/EM difference. EM is acutally the emission of "stuff" whilst sound is the propogation of energy through a medium and without the medium there is no sound just the vibration of the original source.
Waves are a term used to describe the solutions to the wave equation. While sound waves are a propagation in a medium similar expressions describe effects that have no transmission medium.

Don't even get me started on the Finder's utterly, utterly useless "alt-tab" - what a pointless piece of crap. You simply _CANNOT_ switch windows with it, only applications! Great, you can switch focus to the most recently used window in one app or the most recently used window in another, but there is NO FUCKING WAY you can change amongst those app's windows without using the mouse and going to the "window" menu or using "expose" (all involve several distracted seconds on that bastard touch-pad mouse thing)./P>
You do know about "alt-esc" to change windows within the same application?
Calculating pi is a series of mathematical operations where you can't do the next one without the prior because you need the remainders.
That's not entirely true. There exists a digit-extraction algorithm for computing pi starting at the nth digit, without the need to compute any other digits. The only catch is that it only works on base 16.

I was under the impression that iTunes did have the option of buying only as an entire album but don't think I've seen many albums that way.

I guess I'm nitpicking a funny comment, but prions are made of amino acids (think protein) and not nucleic acid as is the case here with DNA.

Most people spend that time backing up code to personal computers or otherwise stealing IP belonging to the employer.
I'd say that is an overly broad generlization.
I guess that makes this book, Noah's Flood, a bit less interesting.

That would be Who Mourns for Adonais? from season 2.

This reminds me of a comment I heard early in my career at Intel, when the 387 (the original match co-processor, anyone remember those?) went on sale:
There were earlier Intel math coprocessors for the x86 line I believe.
However, your point is still valid.
It's not very free then is it?
