I'm a chemist, and you're quite right. Carbon dioxide does store energy that an IR transparent gas would not trap in our atmosphere. But you glibly assume that it is easy to measure the effect of this trapping on global climate. This is not true, and is the reason there there is active debate to this date, even among responsible, non-oil funded scientists over the degree of the effect.
At any rate, this effect *is* secondary to the effect of the sun's output...it is the largest source of energy for our planet, and any change in its output, even small ones, makes a large difference in our climate.
This is why we have seasons...and seasonal changes
are quite large and result from small changes in the sun-earth distance.
If this report is true, and the sun's output has in fact increased over the last decade, it would be an important factor to account for, that to my knowledge, has not previously been considered.
And it is at the same time bad news. If true, then
human behavior may not be as responsible for climate change as we all have thought, and that makes the effects we would like to avoid that much harder to avoid....
...sodomy still illegal in 13 states, the supreme court has ruled it perfectly acceptable to arrest someone for a minor traffic violation, and if John Ashcroft deems you a "hostile combatant," you can kiss your rights goodbye in most districts of the united states.
Key difference: Listen.com requires windows. Apple is doing this to make an apple version, because there has been little effort on the part of 3rd parties to cater to apple users.
its like asking what does windows have that Linux doesn't for 200 dollars.
And that's my point. You can buy an *operating system* for about what they're charging. I paid $79 for jaguar. I mean all jokes about emacs taking over the world aside, it is *just* a text editor, right?
What does it have that gvim or emacs doesn't that is worth $150?
And don't tell me to RTFA, because I have, and I still don't have an answer to this. From the people that use BBEdit or are planning on using this new lite version, why?
The LGPL was born to address this problem. The GNU folks argue that if you link to a GPL'd library, your code must be GPLed as well. The LGPL is not as strict, and thus many useful libraries are LGPL instead of GPL - allowing other licenses to exist on a linux system. Not everyone agrees with this interpretation, though.
Actually, if you use fink, you've noticed that the shared libraries in Apple's X11 distro are named in a non-standard way. I've spent days recompiling things that I'd compiled before I noticed there was a problem.
AFIK particles without mass move at c. As for tachyons, I'm a chemist, not a physicist. I'm not familiar with any of the theories to know much about them. I'll refer you to what I found when googling,
here.
The correct statement is that matter cannot acheive speed beyond c. You can still accelerate, it's just that the change in momentum results in changes in the particle's mass.
0. When I say I want openMP added to gcc, that sort of implies that I want the compiler directives added, and the library routines added to the standard libraries that are shipped with the compiler. I realize gcc isn't going to affect any environment variables.
1. I write scientific code. That's how I know openmp. I think it's great for that.
2. It's not really overkill, because it's quite easy to program for (in a portable way!) Much easier than fork(), and IMHO easier than pthreads.
3. Admittedly, I've never needed much in the way of IPC for the codes I've written for smp (scientific codes on smp machines don't need much of it) but you could probably use a pipe, a socket, or whatever else. I do mostly want it for the scientific uses, though.
4. MPI is good. But openMP is like 1000x easier to write for, and on good hardware is usually better... for my problems.
5. If IBM, or apple even, makes affordable, good smp boxes with this processor, openmp would be quite useful.
6. The same features it's good at in science ought to make it perfect for other processor intensive tasks. Anything that needs a for (do) loop can be scaled quite well. Anything that has chunks that don't need communication can be scaled well as well. I imagine video/sound encoding might be easily parallelized using this...much easier than pthreads, and for this mpi would be overkill, don't you think?
7. All I'm saying is that openMP is out there, is supported on most commercial compilers, and it's noticably missing from gcc. *I* would use it. I suspect many more people would use it if it was available.... especially if 4 processor boxes become available on the commodity market as people seem to be expecting (dreaming) in this topic.
All this talk about SMP machines coming nicely from this chip (and IBM's supposed workstation/linux aspirations) has me wondering something. Has anyone thought about adding openMP support to gcc? I'd give my eye-teeth for that. (Well, at least my wisdom teeth.)
I already know about OmniMP and OdinMP, but I want openmp natively in the compiler. Anybody know more than me?

An alcoholic is always an alcoholic. George Bush, probably by his own admission, is simply an alcoholic who has stopped drinking.
Problem is fixed. I updated, and it recognized my newly installed X11 3 beta fine.
Yes. There's this little company, Microsoft, I think it's called, working on it right now.

Did you work for enron too?

Best of both worlds with pyLint? It claims to do type-checking based on the source, but it seems to be in an early state of development.
Also (though this doesn't check types), pyChecker can track down a few common errors as well, and seems to be more mature than pyLint.

That said, the opengl support makes pymol nicer.
Install vncserver on the winxp box. Install vncclient on the iBook. Rinse. Lather. Repeat.
It tastes like burning.

Long live the laws of thermodynamics!

We give no comment but the following: Buffy has been informed.

Don't buy into the megahertz myth. Just because the clock speed is greater means nothing. I'd still bank on the pentium.
Until recently, ARM chips designed for handhelds didn't do harware floating point math!
Just a thought...
You might accept payments there, but daily, weekly...often anyway...take the money out and put it in a real bank.
Paypal shouldn't be used as a bank account. They're not a bank.
But GNU's Not Unix, damn it!
