Personally I think that geothermal energy is still a method of energy production that has yet to be tapped on a more massive scale.
Strictly speaking, you are correct, geothermal is a method that hasn't been tapped on a massive scale (outside of a few places like Iceland). Problem is, there are issues with induced earthquakes with geothermal. Google Basel Geothermal for an example...
Yes! I saw that as well, wasn't mentioned in the summary. This is the first time i've heard of a dark molecular cloud? So it blocks out all light from the stars behind it and somehow there are no stars in-front of it even though it's 500 LY away?
500 LY is our local neighborhood, galactically speaking, not even one quarter of the way across the arm of the galaxy's spiral that we are in. The map at the bottom of this page gives an idea of the scale of 500 LY. For comparison, let's look at the Orion nebula (middle "star" in Orion's sword). It is about 1200 LY away, and there aren't very many stars directly between us and it, even though it is about halfway across the arm that we are in.
"How they are formed is unknown, but clouds such as this are thought to be a birthing place for new stars."
I thought Nebulae were responsible for that?
Nebula are typically what's left over after a star dies, and yes can provide the matter for new star formation. But that isn't the only (or even main) mechanism. Anytime you have a large concentration of matter in space, gravity has a tendency to pull it together and form stars.
And slow film has its uses. I recently bought a Yashica Electro 35 GSN, which has a nice 1:1.7 45 mm lens. I want to use the lens wide open to get really shallow depth of field - an effect I've come to really like. But to achieve that during the day, I'm going to need some slow film; likely ISO 50 or 25. Probably some Adox/Efke or Rollei.
A neutral density filter is another way of dealing with this problem...
I'm tired of people saying their apple runs just as good four years later. Its almost technically impossible. Hardware degrades. It has nothing to do with the OS and no, the component quality in a macbook is *not* that much better than what you'd find in a high-end laptop. I guarantee you its NOT running as well as the first day you bought it, you just can't admit it to yourself. No CPU, RAM, harddrive, etc etc etc is going to run as well as it did after four years of usage unless its never getting used in which case the same principles can be applied to any other computer.
Not to defend Apple here, but please explain to me how, for example, a CPU or RAM "degrades". As far as I can tell, either it works or it doesn't. Does RAM run slower? That would be hard to believe, because it is externally clocked by the MB.
That's not to say that RAM or a CPU won't eventually -fail-, but until they fail they don't really degrade.
Before anyone replies to this blog post you really need to read the whole thing. It goes into quite a bit of detail about engineering what is very possibly one of the most complex man-made things in the history of the world.
Exaggerate much? It's just an OS, FFS, not the frigging space shuttle. If it is the most complex man-made thing in history (hint: it's not), then Microsoft has a seriously screwed up engineering process.
I've been using Unix for decades, and I never did get to like those verbose switches for chmod. It's so much quicker to use the numeric ones, e.g. 755 vs. +rwxr-xr-x.
Easy to remember how they work when you consider that 4=read, 2=write and 1=execute and you just add them up as required.
The "verbose" switches are good if, say, you have varying user permissions on the files which you want to keep intact, but you want to change all of the group permissions to be the same. Using the numbers would wipe out the varying user permissions. Using the g switch would leave the user permissions alone while setting all of the group permissions...
If you are going to condemn Palin for lack of experience, than you should be voting for McCain because the Democratic nominee has NO executive leadership experience.
If that is your sole criteria, McCain has no "executive leadership" experience either.
I would also point out that Obama has run a national campaign that unseated the Clinton political machine, and managed it very intelligently. If the way he has run his campaign is any indication of how he would govern, I would say he has clearly demonstrated his executive leadership capability.
We need to continue drilling the McCain campaign on economic issues.
We need to continue drilling Obama on the constitutionality of the things he wants to do.
We need to continue drilling the media to get more focus on the third party candidates
You talk about renting like it is the worst possible thing in the world, even worse than taking on an ARM that you clearly don't understand and can't afford.
Here's the thing, the interest you are paying on the loan, that's an expense. The maintenance you are putting into the property, that's an expense. The property tax that you have to pay on the house's (inflated) value, that's an expense. Buying a house isn't all investment, it also comes with a bunch of great big expenses.
I'll join the chorus and say that I sure as hell don't want to bail your stupid ass out. I didn't take the risk, you did.
Keeping a strict separation between "work" email and "non-work" email is not always practical. How do you classify this email:
"Here's the document you asked for. BTW, thanks for inviting us over last night. We had a wonderful time."
Should you send that as two separate emails, to two separate addresses? And, what if you receive this sort of email? Do you respond back from one email address "Thanks for the document" and from the other "we really enjoyed having you over"?
Actually, it's quite simple.
There is nothing wrong with having the "thanks for dinner" in an official email. A reasonable amount of personal communication is appropriate from a govt account.
What is not appropriate is to conduct any official business via a personal account.
It isn't secure, it violates the principle of non-repudiation, and it isn't accountable.

Some of the most pleasant managers I've had, didn't have a clue about the technical aspects of what I do, but they did trust me when I gave them a time/cost/resources estimate.
Sure, that can be nice when it is you, but what about the less-than-competent/ethical cow-orker who can endlessly blow smoke up the technically clueless manager's ass?
A good manager has a good bullshit detector, which means technical competence is necessary.
I even did it using WINE because the PC with the writer was a home Linux server, and it worked perfectly. I very much doubt you could make it THAT much simpler, except possibly joining the two programs together and incurring the wrath of the DVD industry by doing so...
A first guess would be that the sphere of 500 ly radius around Earth would contain (100,000,000,000 * (500^3) / (100,000^3)) = 12,500 stars. Of course, this makes some assumptions (uniform star distribution, spherical shape of the Milky way) that aren't true, but it's a good first guess. Accounting for the disc shape of the Milky way would probably increase this number quite a bit.
Yeah, your estimate is conservative.
But not all stars are created equal. You have lots of dwarfs and giants out there. My understanding is that in this part of the galaxy, <10% of stars are G type. So even if we bump up your estimate to 50,000 stars within 500 ly, that only gives us a pool of 5000 stars that could possibly host planetary systems similar to our solar system.
Given that 500 ly is half of the average thickness of our galaxy, I would say <5000 stars in that volume isn't very many. YMMV

This company sells a thing called the "Wipemasster" for mass wiping of up to 9 hard drives at a time.
Simpler than a PC, definitely. Cheaper? Not really at $2500...
Definitely my favorite PF album!

Good old V.35, now that brings back some memories!
The issue is that this ignorant view may be perpetuated in America. I have never heard anyone in Europe utter such crap.
I wouldn't be so smug. According to this, the problem definitely isn't just isolated to the U.S.A......

As for Palin lying... even if she did lie, I don't care.
I guess that says a lot about your character.
When she does something that is worse than hanging out with a known and unashamed terrorist, let me know.
I don't know, how about marrying a secessionist?
And don't pretend that you wouldn't be using that to skewer Obama if the shoe was on the other foot.

That probably says more about Slackware's (lack of) package management than anything else. I'm using k9copy (and DVD::Rip) on Debian without a hitch.
