Annnnnd here's a reference for you: http://zebu.uoregon.edu/1998/ph162/l4.html Says 380kWh per day during winter at minimum. Just curious: Where did you get your energy consumption stats from? Do these include energy consumed to power a vehicle?

Given this information, we can assume that the life expectancy was 40 years or under when U.S. copyright law was first enacted. This would mean that a 12 year old would be safe to assume his creative work would be protected his entire life. -
Re:A rip-off artist gets his just reward
Reading the tortured history of this case was a real eye-opener. I hadn't really thought about the lengths that some people will apparently go to steal from the community, lie to regulators, and engage in what must have been a very expensive legal fight.
You've got to wonder what the motivation is. Is there really that much money in model train software? Or is this someone who has money to throw at whatever they want?
Dig around a bit... and you find some interesting things.
It seems Katzer and his parnter have made a sizable donation to the University of Oregon in the tune of "$1.25 million for computer labs, software and a technology endowment fund." That's a nice chunk of change to throw around. Where does it come from?
It's interesting to note that Katzer shows up in a number of roles from software development to a model train store. I suspect ongoing concerns are something along the lines of his LinkedIn profile:
Matt Katzerâ(TM)s Summary
KAMIND Associates delivers Microsoft solutions for small business customers since 1998. We solve your IT problems with the following solutions â" eCommerce sites for samll business using Microsoft Commerce Servers, Microsoft Small Business Server and Microsoft Retail Management System (POS) Solutions for specialty retailers. As part of our service model, we work with customers to develop an integrated IT services plan that solves the customers need and results in long term bottom line savings.
That seems pretty straight forward. But there's some other oddities out there. Take this blog entry of a Microsoft manager for example:
Matt Katzer runs an ISV called KAM Industries. They build software for the REALLY big railroads - railroad yard automation, engine automation, that kind of thing. Software that makes really big, heavy stuff move when and where itâ(TM)s supposed to. Matt told me that they also do similar stuff for model railroads â" HO, N, and O-scale stuff. They can completely automate, and simulate very complex setups.
If that werenâ(TM)t cool enough, Matt has built all this on top of Microsoft technologies -
.NET Framework, the Compact Framework, WMI (okay, not REALLY MS tech, but it counts), XML, Windows Server 2003, etc.Eh, what? Is this more than model trains or was Katzer simply exaggerating to impress?
Side note is a comment on the blog:
Matt Katzer was my first manager at Intel and the reason that I moved out to Oregon to work for Intel.

If you're on a Mac, you could try Mellel
Mellel is the best word processor for scientific writing I've ever seen. Its main advantage is stability (of the program and of the layout). One downside is, that it doesn't have a formula generator, but you could use either Grapher or LaTeX Equation Editor to do the job. Here are a few links: On equations on the Mac and Mellel's Homepage

Nope -- but there are better ways to do LaTeX
First of all, you have zero chance of finding anything better than LaTeX for mathematical/scientific typesetting. However, there are ways of solving lots of the problems you mention without chucking LaTeX out the window.
- Frustrated that you're constantly having to download and install new packages, fonts, etc.? Try the everything-including-the-kitchen-sink distribution, TeX Live. If you're running Mac OS X, there's a great Mac-specific version of TeX Live called MacTeX, which also includes a number of front-end apps for editing, managing bibliographies, spell-checking, etc.
- Hate the standard (La)TeX font, Computer Modern? You're not alone. For free, math-capable fonts (most of which are included in TeX Live/MacTeX), check out this illustrated survey. If you want the ability to use OpenType and other installed fonts on your system, as well as foreign language scripts, unicode, and other modern font features, check out the wonderful Xe(La)TeX and its fontspec package, both included in TeX Live/MacTeX (of course)
- Want the ability to do real programming in (La)TeX, with a full scripting language? Check out LuaTeX (although it's still very much a work in progress).
- Want a good LaTeX front-end/editor? IMHO, Scientific Word and Lyx try to hide the complexity behind a WYSIWYG interface -- but this makes things even more confusing, because the complexity is still there, but now it's invisible, so it's impossible to diagnose why your document doesn't look the way you want. What you really want is a text-editor with built-in templates, push-button PDF compiling, and other TeX-specific features. One of the most popular editors (justly so) is TeXShop, for Mac OS X. A cross-platform program called TeXWorks is in development (led by Jonathan Kew, who developed XeTeX), and promises to bring TeXShop's advantages to all platforms. If (like me) you're wedded to Emacs, there's the fantastic AUCTeX editing mode for all things TeX-related.
- Read LaTeX books designed for users, not developers or those interested in the "theory" of typesetting. This means, in my opinion, to stay away from anything with "Knuth" in the byline. I really like Leslie Lamport's introductory book on LaTeX, which you should be able to track down at almost any university library if you don't want to buy it.
Above all, be patient, and be open to learning. It's understandable that you want to do powerful and flexible document processing, without having to learn a whole bunch of commands. Unfortunately, this has a lot of similarity with people who want to program computers without learning a programming language. ("Why can't the computer just understand what I want it to do, in plain English?") Any program powerful enough to do everything you want is also powerful enough to do lots of things you don't want -- and because the computer can't read your mind, you have to learn how to tell it exactly what you want.
Cheers,

Re:Growing Asparagus on Mars...
OK! I was hoping someone with high speed internet access would do this for me, but I did it. NASA says that much of Mars' atmosphere was lost to pressure from the solar wind, but "[...] solar wind erosion was likely much more effective in the past than it is today." Some believe that Mars' atmosphere was lost mostly due to collisions from a variety of potential impactors. Apparently you can or once could take a class at uoregon which would teach you that there was insufficient temperature for [Martian] water to remain as a liquid, so it froze out leaving CO2 as the primary component in the atmosphere. Which is OK, that's an atmosphere! We want it for warming (CO2 is great) and for providing pressure so that we can survive with an air mask (for which purpose it would be fine.) I mean, an oxygen atmosphere would be dandy, but any atmosphere would be an upgrade. However, it might also have been 7.5 bar of CO2 when Mars was young, which would be a bit excessive for our purposes. Actually,
.5 bar would probably do the job, although it would certainly limit the value of suction-based pumps in a non-pressurized environment... -

Re:I for one will have a tab open permanently

Re:Trying to regulate every little thing is stupidWell I have a modest proposal:
- Reduce the human population by 90% (preferably using a humane manner; like fewer babies). Instead of 6 billion, you'll have 600 million. There will be plenty of resources for everyone to go around, and pollution will be decreased by 90% of current levels. Well, then, the solution is obvious. So obvious, in fact, that Jonathan Swift had it figured out quite a while ago. -
Re:Actually, it really does make sense
Don't worry, the Republicans are certain to make sure we hold the next president responsible.
As we all should, not just Republicans. What we're going through is a "correction", tied heavily to the housing issues in this country and being tempered by the Bush tax cuts, a weak dollar that is helping exports and inflation that is far from out of control (higher oil prices help to act as a tax to keep inflation in check). Unemployment numbers have inched up, but are still only around 5.1% (something much of the world would love to have).
We're far from a catastrophe, and it's doubtful once things start to improve in the final quarter of this year that we'll have experienced the prerequisite three quarters of negative economic growth necessary for a "recession" to occur. We've had a long period of growth, and in any free market society there's going to be contractions and corrections.
Even in the credit area, supposedly most hard hit by the housing debacle there is no shortage of credit. So far, the Fed has done "OK" by providing liquidity and keeping interest rates low. Hopefully they don't interfere too much more than they need to.
Meanwhile, while the press screams about a recession, economists just aren't seeing one, and wouldn't bet on one either.
What _will_ exacerbate the problem is the next administration tinkering and meddling too much to attempt to correct a "non-problem". Jacking up taxes on the people that give us jobs, and pushing more protectionist policies could easily push us back in the wrong direction and change what looks to be an extremely mild correction into the recession everyone is whining about but so far hasn't quite materialized.
And honestly, I would much prefer to see different parties in both the WH and in control of Congress. The economy loves political deadlock, and it may be the only thing to control insane spending by the government, even if only slightly. I was disappointed to see the Republicans spending so much, and I can only imagine what the Democrats will do... -
Logical fallacies
I say this because thus far, we've discovered nothing whatsoever that is non-reproducible about the brain's structure and function
You got to the fallacy of your argument quite quickly - in the second sentence. We don't fully know how the brain works, thus there are likely entire mechanisms we haven't discovered yet. Are those unknowns reproducible? Who knows - simply to know of something does not mean you can create it at will. What we know about the brain so far has no bearing on what we find in the future and whether that will be reproducible.
The other fallacy is that we are held up by our current computing power. That's been a running excuse now for decades, and it's hogwash. I'm sure you know what it means to be Turing Complete - essentially any Turing Machine can emulate any other Turing Machine given enough execution time and storage. There are creatures with extremely simple brains. Put two and two together, and why can't we simulate a worm's brain?
This is from almost a decade ago - 1999:
"C. elegans has one of the least complex nervous systems of any life form on the planet," says Lockery, a University of Oregon biologist who has studied the worm for twenty years. "Its brain has only 302 neurons, or brain cells; that's compared to about a hundred billion neurons in a human's brain. It is the only animal for which we have a complete map of the brain. It is likely to become the first animal for which we can gain a fairly complete understanding of how the brain controls behavior."
So we have a full map of this animal's brain of 302 neurons for a decade. Well, where are the Flash and Java worm simulations floating all over the net, showing a little virtual worm moving around based on the stimuli of our mouse? -

Re:too little, too late?
I use TeXShop for all of my LaTeX needs. It's not just a LaTeX editor, but also contains an easy-to-use environment to create PDFs on the fly. It is also bundled with a graphical BiBTeX editor to store bibliographies. Way better than the command-line tools that I've used on my old FreeBSD machine
:).As for LaTeX tutorials, I use "The Not So Short Introduction to LaTeX 2E." It's a very good tutorial that will get you started working with LaTeX code. I use LaTeX for all of my research papers except for those that employ the MLA format (LaTeX was designed for scientists and mathematicians, not keeping English and history majors in mind. But sometimes a science/math student needs to write an English paper, and I haven't been satisfied with existing MLA themes for LaTeX). If you must use MLA, just stick with Word.

Re:I call BS
Portland, Oregon. But yes, most programmers I know are indeed either contract or government workers.
Your sample must be really skewed; I know a couple of junior to mid-level programmers working for Intel in Beaverton, and I believe at least one of them makes 80+ an year. A very quick and cursory web search found quite a few jobs paying well over $40000 in Oregon. For example, a .NET engineer position here was paying up to 48000/year, and that's really entry-level. -
To Quote Milton
Only because I have so few opportunities to quote Milton on
/. and the parent comment brought him to mind:
I cannot praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary but slinks out of the race, where that immortal garland is to be run for, not without dust and heat. Assuredly we bring not innocence into the world, we bring impurity much rather; that which purifies us is trial, and trial is by what is contrary. That virtue therefore which is but a youngling in the contemplation of evil, and knows not the utmost that vice promises to her followers, and rejects it, is but a blank virtue, not a pure; her whiteness is but an excremental whiteness.
John Milton, Areopagitica: A speech for the liberty of unlicensed printing to the parliament of England
Of course, he recommends Spenser, not child porn, for the contemplation of evil. -

Acoustic EcologyThe connection between music, the environment, the ear and the mind is seriously studied and is reasonably well understood.
http://en.wikipedia.org/wiki/Psychoacoustic_model
Psychoacoustics alone will never lead one to a "reasonable" understanding of that rather elaborate set of connections, it's fairly mechanistic and limited to subjective responses. You'd be invoking culture and society: much more elusive, chaotic, and difficult to measure. Like most psychology, it lacks sufficient inputs. I concede that psychoacoustics has made some pretty big leaps recently, but not that it understands the big "connections."
To get a handle on "the connection between music-environment-ear-mind" you'd have to be studying the more interdisciplinary "acoustic communications" which is only studied in a relatively limited way as yet, sometimes called "acoustic ecology" or soundscape studies. The World Forum for Acoustic Ecology is a good place to start getting an overview.

World Soundscape Project
This sounds like a natural fit with the original vision of the World Soundscape Project, especially since these are ambient field recordings. Too bad they ran short of funding and the momentum faded, I think they would have taken it somewhere like this. I like the fact that they're hoping to showcase changing soundscapes over time. It would be great if the GE community can contribute. If this stuff interests you, check out the literature on acoustic ecology.

Re:How the hell?
dust on the moon falls back to the ground at the same speed as a dropped hammer
yes but you're missing an important part - the moon's gravity is so weak, you could probably throw a hammer and put it into orbit, because the speed of a dropped hammer is actually pretty low.
So the concern is that some mechanical process, maybe a fast spinning wheel or maybe the use of explosives, will actually put dust grains into orbit. It turns out, the moon already has a very thin atmosphere:
http://zebu.uoregon.edu/~soper/Moon/atmosphere.htm l
composed of a few atoms that are basically in orbit. So the point is, it is possible to create a dust atmosphere on the moon. We want to be careful when we start mining or whatever. We don't want to make that atmosphere significantly worse, because that dust will gum up machines. -
Re:Main sequence evolution
Well, actually most models I've seen move up and to the left until turnoff. I was not all that happy with the movie because when you set it to one solar mass if givens the wrong luminosity and lifetime but it does get the basics of the evolutionary track. Here is another link that looks like what I remember from grad school, though without references http://zebu.uoregon.edu/~imamura/122/feb23/LMS.ht
m l. At higher mass what you say may be true. Fig. 10.3 in this link http://www.astro.utu.fi/~cflynn/Stars/l10.html shows a 5 solar mass star behaving as you describe.
My mistake was getting the direction of the axis wrong, something every one of my teachers has warned me about. -
Re:More but but but....We are on the up-swing (interglacial) from the last ice age that ended only about 10,000 years ago. Actually, the paleoclimate record over the last 10,000 years doesn't support much warming; if anything, there has been more cooling (e.g., Vostok). There are a number of factors (sun cycles/solar activity, atmospheric content and even the magnetic field) that cause temperatures to rise, but even if every power plant and factory were closed and all use of fossil fuels was ceased, temperatures would still rise. More recent reconstructions also support cooling (pre-industrial) more than warming (here).
While it may be a temporary downswing geologically speaking, and there will be future warming, that warming will be much more gradual than what is going on right now. The current warming is also largely due to our own activities, and we can do something about it, if we decide that the costs of not doing anything are higher. -
Get a Mac!
Just get a Mac. It's unix under the hood and its a fantastic environment for LaTeX. TeXShop (http://www.uoregon.edu/~koch/texshop) is an excellent open-source application for composing LaTeX documents (though still not as good as Emacs+auctex IMO) that comes with its own, very good previewer. And if need be, as long as you have 2GB of RAM, you can run linux in a virtual machine with Parallels at near-native speeds. I run Ubuntu in such a VM and its great -- though you still have to compile Emacs yourself if you want anti-aliased fonts, unlike Emacs under OS X. (I strongly agree with the numerous Ubuntu recommendations already given; it is a snap to install and keep up to date.)

Re:Nobody To Cheer For
Personally I don't use OO because I can't swap files with people with whom I co-author scientific articles. MS Office and Open Office equations STILL don't work right (and before you LaTeX fanatics step in, neither of us speak that language).
If you actually do any serious scientific writing that requires mathematical equations or formulae, then you really should make an effort to learn LaTeX. Rather than whinge about the lacking equation editors in Word and OO, just take the time to download TeX, a user friendly editor (like TeXShop for the Mac) and the manual over at Wikibooks. Once you've grasped the basic concepts (which only takes about 20 minutes of effort), then writing complex documents is easy. I learned LaTeX at university for writing technical reports in Engineering and found the whole bibliography and reference management system (BibTeX + LaTeX) an absolute lifesaver. -
The real advantage to Agile...
... isn't the whole issue with interuptions. That can be handled differently depending on the work (if you are making life-saving heart monitor software, you had better fix a bug the moment it comes up... if you are making some tool that other developers use once a week, a bug isn't that big of a deal)
The real advantage is illustrated in the age old swing cartoon. By using scrumm and delivering sprint demos often to the user, they can see how their money is being spent, and can present requirement changes to the user faster, thus eliminating the need to make resounding changes right away... Agile development anticipates requirement changes, instead of ignoring it like past methodologies. Is it the best? Probably not... is it a step in the right direction? You bet your ass... -

Also, project management skills are necessary in any kind of work in IT (and most other fields, too).
At UO the software methodology class was treated as a "capstone" type of class and we had to do some reasonably substantial projects that kept us working late hours. -
Re:Yes there is such a thing as music piracy
It sounds like the modern definition (copyright infringement) was added because people used it in that sense. Webster does it sometimes (although some regard Webster to be of lower quality).

Here are some examples, via the Oxford English Dictionary:
"Banish these Word-pirates (you sacred mistresses of learning) into the gulfe of Barbarisme."
Thomas Dekker, The Wonderfull yeare, 1603.
"The public curiosity was imperfectly satisfied by a pirated copy of the booksellers of Dublin."
Edward Gibbon, Memoirs of My Life and Writings, 1790.

Section 17 (Virtualization) FC6 uses Xen 3.0.2, I know Xen was in FC5 but I haven't had a chance to play with it. The release notes mention something about it being connected with the installer, so perhaps I'll get a chance.
Section 22 (Package Changes) Interesting removals IMHO are: mozilla, xscreensaver, gkrellm. I'm sure all can be found in the Fedora Extra's Repo or some place similar. I'm not a big fan of where some of the desktop apps are going (eg. I hate gnome-screensaver), but the beauty of Linux is it's quite simple to solve this problem.

Milton
I think George Orwell may just have been before his time...
Actually you can go all the way back to 1644 with John Milton's rather important essay called Areopagitica -- "A speech for the liberty of unlicensed printing to the parliament of England." (Wikipedia entry here)
Back in Milton's day, the King of England decided the new printing press was a pain in the ass since every time the King did something corrupt, the printers would crank out leaflets blowing the matter wide open. Kings, who remembered how they used to be gods, really didn't like little common people criticizing them. He made laws that required an official seal from the King to be permitted to own and operate a printing press, and made the penalty for being found in possession without the official seal rather severe (death). Interestingly, a printer could immediately lose a seal if he printed something the King didn't like, and the King's men could take time letting you know you no longer had that seal.
Not many printers decided to print leaflets critical to the King then.
Milton challenged this by taking the King's argument of "protecting the people from harmful falsehoods" at face value and discovered that if this was the King's value, the presses instead must be free. Truth and falsehood must be permitted to grapple if truth is to be found. Milton's essay won over the minds of men and historically has held true. Societies and religions that accept criticism and deal with the ugliness of open argumentation have thrived and rised to the top. Those that surpress truth and only permit state or religious-sanctioned speech have sunk to the bottom.
So EU... what direction are you going? All of us in every nation and society need to oppose the elites when they try to led down this status quo-preserving path of societal decay. -

Re: Fermi's Paradox!
Thats Fermi's Paradox!:
"The story goes that, one day back on the 1940's, a group of atomic scientists, including the famous Enrico Fermi, were sitting around talking, when the subject turned to extraterrestrial life. Fermi is supposed to have then asked, "So? Where is everybody?" What he meant was: If there are all these billions of planets in the universe that are capable of supporting life, and millions of intelligent species out there, then how come none has visited earth? This has come to be known as The Fermi Paradox.
Fermi realized that any civilization with a modest amount of rocket technology and an immodest amount of imperial incentive could rapidly colonize the entire Galaxy. Within a few million years, every star system could be brought under the wing of empire. A few million years may sound long, but in fact it's quite short compared with the age of the Galaxy, which is roughly ten thousand million years. Colonization of the Milky Way should be a quick exercise."

olbers paradox
that the night sky is not the temp of the suns surface is called olbers paradox http://jersey.uoregon.edu/~imamura/123/lecture-5/

I believe the resoluiton of this paradox is one of hte outstanding successes of the expanding universe idea discoverd by hubble -
Re:The simple answer
LaTeX's markup makes so much sense that a WYSIWYG tool isn't necessary, for even the man on the street can be just a productive with doing it up in a text editor.
I love LaTeX (I have TeXShop open in the background right now!), but I have to argue with the assertion that the uninitiated "man [or woman! -ed] on the street" can be just as productive as s/he was in Word. Compare Word's graphical table builder and tab ruler, the result of about 20 years of noodling around with the best user experience for creating such things, with \begin{tabular}{|r|r@{.}l|}. OW MY WORD PROCESSOR.
Even if you give everyone a pocket syntax reference, unless you have a TeX ninja working overtime on your templates, you'll still end up with a lot of documents that look like academic research papers. This is fine if what you're writing are academic research papers [hi!], but for most corporate communication people are accustomed to more effortless (read: WYSIWYG) control over the output. (This is, of course, usually a terrible idea, resulting in official RIF memos from HR written in Comic Sans; I think there's a happy medium somewhere in between.)

Re:fusion
It's not exactly a neck-and-neck race for the title of "Most Abundend Element."
Nor abundant. Spellcheck would help you. That said, abundance wasn't the issue, and if you were much good at this, you'd realize that; you can fuse the output of hydrogen fusion too. Read what I wrote again, and keep reading it until you understand it.
whatever ridiculous engineering thing we're going to end up doing when it comes time to leave the nest and expand past Sol. Well, before we leave this planet, ...
"This septic tank isn't big enough. It barely handles the staff, and none of the prisoners are in the jail yet." "Well, it's fine *before* the prisoners get here."
Way to miss the point.
And if we're going to be leaving Sol any time soon, we'll have to pass this little thing on the way out called "Jupiter." I hear it has a little bit of raw hydrogen.
Way to continue to miss the exact same point. You really shouldn't take that tone in your voice until you've managed to stop being a dumbass.
"The bulk of stuff that isn't out in the sticks (galactic style) is in gas giants or stars;"
If you're talking interstellar scales, there are nebulae.
[G]alactic nebulae, [] are composed of the interstellar medium (the gas between the stars, with its accompanying small solid particles) within a single galaxy. Today the term nebula generally refers exclusively to the interstellar medium.
Yeah. Except for the stars, the Milky Way is a nebula. In general, wait until you know what you're talking about before you talk back; all you did was to accidentally repeat me. Nebular matter is the result of stellar wind. Now, before you get all huffy and dig up something that says 5% of the galaxy is nebular matter, please try to focus.
(I'm guessing for the sake of the example; don't waste your time getting an almanac.) Ten percent of all oil is bound up in grass. Does that mean grass is a good place to get oil? No: it's spread far too thin over far too big a space (the great plains) to be usable in any realistic fashion. Sure, let's say 80% of the salt on Earth is in the ocean. Why do we mine it? Why don't we just dredge the ocean? Let's say 50% of all topsoil is spread across the dustbowl states. Why don't we collect it? Why do we go to the effort of creating it?
One day, you'll try gathering something on a large scale in the physical world. On that day you will learn about the overhead of doing the actual collection. On that day, remember this post.
"Remember also please that the solar wind isn't really that abundant; it's just that the universe is ginormous."
But Jupiter is.
Wait, let me get this straight. I was talking about a timescale in which stars aren't much of a source of hydrogen, and you're still stuck on mining Jupiter? Has nobody pointed out to you how much bigger Jupiter isn't than our sun?
By the way, have you actually thought through the logistics of mining Jupiter? (No.) The hydrogen starts several hundred miles below the frozen helium. The metallic hydrogen is 6000 MILES down. Are you going to set up a flying mining base, then send big-ass cables down with balloons? Maybe just a really, reallllllly long pipe? (Is it filled with weed?)
Mining Jupiter is ridiculously unrealistic. There are better sources of hydrogen in this solar system. Quit flogging Jupiter.
Heck, there's enough in those to make Bussard ramjets feasable. ... Lay off the Star Trek.
Ahahahhahahahhaha. Lemme get this straight. First you're going to call Ramjets by their star trek name, falling for the wikipedia deception that somehow they're different than the ramjets from 1906 by Ren -
Re:I wrote my doctorate thesis this way
Word 2003 also has a feature by which you can lock the available formatting styles to the ones you have defined. If you go to Tools > Protect, and elect to protect the styles, it will disallow any manual formatting: the user must pick from one of the available, defined styles.
But of course, I switched to LaTeX: TeXShop and BibDesk make it a joy to use on the Mac.

Links with information...Why doesn't the article link to pages with more information that just a summary?
- The group's website, including movies
- The journal article
Incidentally, this news dates from the end of 2005 - so slashdot is running 4/5 months behind the times.
