Re:Slightly Off Topicdoesn't the coriolis effect have something to do with the way the water rotates in your toilet when you flush, too?

Penn State Physicist
NASA Marshall is funding the work of Prof. Gerry Smith, formerly of the PSU Physics Dept. (where I got my Ph.D. a while back) and who has gone to NASA MSFC
This was posted previously on /. here.
You can seen the PSU antimatter propulsion page here.
He also has tried to sell folks on anti-matter assisted fusion energy at the NASA fusion propulsion workshop that was held in 2000.
I haven't the slightest idea how far any of this will get under the current NASA budget woes.

We'll hear more cuz Astrobiology is a growin field
One of the big reasons we're hearing more of this is that since the fossil bacteria mars meteor find there has been a lot more focus on Astrobiology. NASA Ames has a Astrobiology Academy that is sort of a Space Camp for the 18 to 25 year old crowd that grew up wanting to go to Space Camp (that's us).
There are also a lot of Collegiate program's like Penn State's and some new peer reviewed astrobiology journals.
Sort of a case of we find what we look for. Makes you wonder what the SETI people could do with more funding. -

Re:always assumed this is being done
NSA does not spy/eavesdrop on US citizens.
Well, they certainly DID in the past. Read up on Operation Shamrock, which was the wholesale monitoring of US cable communications. This isn't anti-government crazytalk; this stuff really happened. It's well documented in books like The Puzzle Palace.
Considering the audacity they showed before I am not prepared to say that they do not spy on citizens.
Here is an interesting link about another book by the Puzzle Palace guy.
Read their charter; i'm pretty sure it's not classified.
The current charter is classified. The original 1950s version is available though.
The NSA is super spooky. Read The Puzzle Palace if you have the time. A bit dry in parts, but fascinating in others. -
Re:Depends on the level.....
Deitel and Dietel's Java texts are also popular.
I recently took a Java class and the prof complained and complained about the lack of "good" java texts and how he might just have to resort to writing his own. The course had used Deitel and Dietel the semester before I took it, but was stopped due to the overwhelming number of errata in the text. When I took it we used Kalin's Object Oriented Programming in Java however the two or three times I used the text I saw errors on a few pages.
If you are looking for only a discussion of OOP topics and not bound to a particular language...
I kinda think that's the topic the person was really looking for, but I'm not sure since he does list the few languages taught. Maybe the person hasn't decided what track they wish to take (OO SE or coding), but I can throw in my $0.02 on this subject. I've taken several OO design and SE classes. This one has changed since I took it, it now uses the Booch book referenced in an earlier post as well as a UML book. Back in my day (man I'm feeling old here) we had a really bad small talk book, but it did drive home selecting a good hirarchy of classes. This other one has also changed since I took it, it now uses a UML book as well. When I had the second class we used Schach's Classical and Object-Oriented Software Engineering (I later used that text in some silly MSIS Grad class I took for giggles). There are a few editions I beleive of that book, we used the one with Java and UML and included a CD with Popkin's System Architech 2001. The Schrach book is an OK book from the SE standpoint, but I think the ordering is a little out of order.
Maybe they'd like to toss all of this out and teach formal software design techniques and include methodologies for proving source code meets the design and things like DFD-SPECS and SPECS-C++, nah, maybe you're right, they probably just want to teach Java's objects to the kids who know C structs. -

tool
well, as long as we're talking about OS's, check out what this tool wrote at my campus newspaper:
here -
Remember that one ST:TNG......where the Enterprise came upon the race that had built very complex, self-sustaining technology and were able to devote themselves to "higher pursuits", like art and music, but who were unable to fix the problems that eventually developed because there was no one left who remembered how everything worked?
sorry for the run-on, but that was my immediate thought when i read Paul Horn's statement that the creation of "computer systems and software that can respond to changes in the digital environment, so the systems can adapt, heal themselves and protect themselves" is the only thing which will reduce the need for "constant human maintenance, fixing and debugging of computer systems." freeing humans for higher pursuits sounds good, but is probably only likely in a utopia. Horn goes on to say "The only way to get efficiency gains in information technology is to take some of the people out." This trend sounds like the steel industry - we'll have more cost efficient processes in providing IT services, but all those educated in that field will end up working at mc donald's.
so what happens when we all forget exactly how this "autonomic software" regulates itself? i guess this is the final word in proving the importance of documentation! : ) ** begging for a flamebait mod**    or we could skip the documentation and just kidnap the children of visiting alien starships when we eventually start dying of radiation poisoning from our super-self-configuring systems.

Re:Why is the NSA in this?
The sole purpose of the NSA is to spy on you, now why are they trying to make your system more secure?
Incorrect. Read the NSA's charter.
Pay attention to section 1, Article 5, Section 3 et. al. The NSA also is charged with creating standards for the security of information held in DoD computers (specifically), other govt. computers (generally), and promulgating those standards for use in other systems. Here is a nice link to the NSA's computer security guidelines if you haven't seen them.
Yes, the NSA spies on people. No this isn't nice. Yes, the government of the USA does some awfully screwy things, like the DMCA. Tarring the whole government with the same brush is simple-minded.
Besides, the code is available for your perusal. If you think the uberspooks have put in a back door, get to work and find it! -
Galactic Collisions and Starburst Galaxies
Galactic collisions are actually relatively common in Nature; typical galactic separations are of order hundreds to thousands of kiloparsecs (kpc), whereas a typical galaxy is of order a few kpc in radius. Moreover, galaxies form along a highly filamentary spiderwork of structure in the early universe, and tend to flow inwards to more massive galaxies.
This situation is to be contrasted with the fate of stars during a galactic collision. Stellar radii are about 10^8 times smaller than the typical interstellar separation, so the vast majority of stars will simply fly right by another. A few stars will probably encounter a direct encounter (particularly if the initial pass is close enough to raise subtantial tides on the stars, which would act to drain energy and angular momentum from the system), but the vast majority fly by unscathed.
It is true, however, that gaseous clouds in the interstellar medium are much more extended that stars, and collision between clouds (particularly giant molecular clouds) will be quite spectacular. It is hypothesized that cloud collisions as well as gaseous flows (bringing tremendous influxes of mass to the galactic nuclar region) resulting from galactic collisions can account for the tremendous bursts of star formation seen in "starburst" galaxies such as NGC 1808.
In any case, the future collision of the Milky Way with Andromeda will be quite fascinating for far future Milky Way astronomers (if any are still around). Or perhaps for astronomers in other galaxies, far, far away...

How can I give back to VA Linux now?As an open source developer, I've made extensive use of the services offered by sourceforge in building and releasing my open source project.
When I graduate from college (assuming I get hired somewhere) I wanted to give back to VA Linux for all they've given to me by purchasing a VA Linux workstation. This seemed like one of the best ways I could say thanks, but now that they're leaving the hardware business, what can I do?

Classic Games are where its atUp at State College, PA (the home of Penn State University), there exists a quaint little arcade filled with all of the classics. You got your Pac-Man, your Street Fighter II (the original), the Speed Racer racing game, you name it. On top of that, everything there is $0.25. Tons of games of every genre and quite the selection of pinball machines. Probably because of the nature of the area (college town), the place was jumpin at 3am on a Wendsday. For $5, you could mash buttons for hours on end. I'm not quite sure how this place stays in business, but whatever it's doing, it's doing a great job of it. I just wish I could re-locate that arcade to my home town.

Penn State
I am a student at Penn State and I work for Rescom which is a group of tech-interested students who others can come to (free) if they have computer trouble. Viruses are by far the most common thing that we have to deal with. In the interest of privacy the University does not filter emails or attachments, so there's a danger that students will get viruses, but whenever we remove a virus we tell students to get a virus scanner and to keep it updated. It seems like people listen when a human being tells them to get virus protection instead of just a web page. Of course no matter what we say not everyone will get scanners, and if there is a new virus it still takes a little while before the scanner-makers will release an update. We actually wrote one virus fix ourselves for Romeo and Juliet becuase it happened to hit Penn State very hard and we couldn't wait for anyone else to come up with a fix. Do any other schools out there offer free tech support like this? It seems to work pretty well for us.

Space Research and Medical Benefits
While we're all talking about potential military misuse of the technology and the destructive power of antimatter, aren't we overlooking one of the coolest things about this research? The second page of the article talked about one of the side-effects of antimatter production was the creation of O-15 which is used in PET scans.
Storage of antimatter is a challenging task, but reaps several benefits. One of which is the generation of O15, a radioisotope used for Positron Emission Tomagraphy (PET) of the human brain. Currently, only certain research hospitals across the world have the ability to create Oxygen-15. Due to its portability, a "radioisotope generator" antimatter trap may be transported to more remote areas for patients who cannot reach these hospitals. A second medical application concerns antiproton radiotherapy of tumors. The NASA Penning trap is being designed with these medical applications in mind.
This fact would potentially offset some of the negatives that antimatter has.
It amazes me the wonderful side-benefits we get from basic research and space research sometimes. Who would have thought that research on propulsion would provide an alternative means to create a rare but medically necessary element in significant quantities? -
Internet2
This is very much like the concept of Internet2 that a whole slew of universities, and i believe some non-profit organizations take part in. They have their own private backbone, "abeline", and they have a priority scheme implemented. And what if someone breaks the rules? If they get caught they are kicked off. Which is a great detterant since this network is much more efficient than the standard internet, and cheaper.

Re:Somebody flunked Physics 101 (you flunked chem)
"Let's see: you take carbon (coal) and oxygen (air) and run a chemical reaction to give you carbon dioxide and energy. Then you add a bacterium and light and get back (Ta Da!) carbon and oxygen."
First of all, there's nothing wrong with this equation - except that you left out the concept of losing mass to energy creation. Since so much energy is contained in mass - it makes sense that you would be able to keep converting your material back and forth and getting energy; it's just that the material shrinks a la everything else in the world, ie: not free energy.
Secondly, in any chemical reaction - there are always other compounds produced from reactions in some amount, some are completely unstable and break down into something else, some aren't... ie: you would also get, Carbon monoxide, Cyanide... and a slew of other carbon-something compounds; just in smaller amounts, so mass is lost that way.
I agree with you 100%, why not just use the solar power and not the plant - well because the solar power can not at this time be converted well into direct useable energy. In a very real way, this will utilize solar power if the recombinant carbon could be used again.
unfortunately your entire argument is flawed in that carbon in fact does not combust. To combine stable C2 with oxygen you need to actually add energy to break it apart and have it recombine with oxygen. I do believe the energy required is more than the energy gained by the fusion of C and O2. As these guys note, "the basis for most coals, is a large, carbon-based molecule that makes up 30 percent of vascular plants such as trees.". Coal is made up of carbon based molecules and not carbon itself.
This is why when you have a fire, you are left with black ash that does not burn; Carbon. -

I have a solution to California's power problem!We all know the reason California is out of power is because of all those energy-sucking PCs.
We also know that Americans continue to grow obese at an alarming rate, and that sedentary individuals such as computer operators and programmers are particularly prone to gaining unwanted weight.
Ladies and gentlemen, you can solve BOTH of these crippling problems with one fantastic new product from Preposterous Corporation!
The Preposterous Power-Cycle(TM) is a specially modified stationary bicycle with an attached generator that produces electrical power as you pedal! Just hook the Power-Cycle(TM) to your desktop computer and voila -- not only can you burn calories and keep fit while working, you can help to reduce California's energy crisis by becoming an environmentally-friendly "human power plant"!
The Power-Cycle(TM) features a real-time display that shows how much power you are delivering to your system. Like a mountain bike, it offers 24 gears, so you can optimize your pedaling rate to your computer's energy needs. Planning to start a floating-point intensive calculation that you will make your Pentium III consume an extra 20 watts? Just upshift to a higher gear so you get more current with each turn of the crank!
The Preposterous Power-Cycle(TM) even includes a built-in 100 kVA uninterruptible power supply that charges as you pedal, so that your computer won't run out of power and crash if you need to step away for a moment to use the restroom. Trust us, the Preposterous Corporation has thought of everything!
Order your Preposterous Power-Cycle(TM) now, and lose weight while you save the environment! Operators are standing by!
And, if you order now, we'll even include a Preposterous Potato Battery absolutely free!
Don't wait -- CALL NOW!

Getting credit cards solely for good credit
I'm a 20-year-old college student who's never had a credit card. I do have some relatively small loan to pay off when I get out of college. Is it really worth it to get a credit card now when I don't have interest in using it?
As a side note, Penn State uses student ID numbers interchangably with social security numbers. This means that fellow students' social security numbers are easy to come by. Do other colleges follow this dangerous practice? -
Pulsar planets
I'd like to draw attention to your mention of pulsar planets. It seems trendy to ignore these results and claim that we've only detected big Jupiter-sized planets. In fact, Wolszczan's pulsar planets were the first confirmed extrasolar planets to be found; they're small; the observations are extraordinarily precise, and showed planet-planet interactions; and it was a surprising result to find them around a pulsar.

Re:moonsIf such moons were similar to the moons of Jupiter or Saturn, their gravity would be way too low to keep an atmosphere and have liquid surface water (you need an atmosphere, because liquid water will evaporate at sufficiently low pressure).
The big difference in our solar system is that the gas giants are far from the sun, hence their moons are cold, which allows the Saturn moon Titan to keep a (mostly nitrogen) atmosphere. With higher temperatures, the gas molecules move faster, and the escape velocity is reached more easily, thus a larger gravity is required.
There was a paper by Darren Williams and two other authors in Nature back in 1997 which discussed the requirements for habitable moons. You can find a summary here. Basically it says that to keep an atmosphere, you need at least 0.12 the mass of Earth (i.e. five times the mass of the largest moon in the solar system, the Jupiter moon Ganymede).
Moreover, the authors argue that the moon must be able to remain geologically active for several billion years (to resupply carbon dioxide), which pushes the minimum mass up to 0.23 the mass of Earth. That would be twice the mass of Mars. -

Re:Liquid carbondioxide?
CO2 can go from solid to gas at 1 atm (sealevel). At sealevel and above(lower pressure), CO2 only exists as a solid or gas. Mars does not have as heavy of an atmosphere as Earth, so my guess would be that it would only exist as a solid or gas on Mars. However, if you've ever seen DryIce (um, most mad scientists mix colored waters with pieces of CO2 together to get a highly explosive substance) you'll notice that, in our atmosphere, it sinks to the ground. It's very heavy and "flows" through the air like water. My guess is that it would emerge from the ground and "flow" along the dusty surface of Mars, causing "canals".
Oh, and CO2 will exist as a liquid. But only at higher pressures (~5.2 atm and up (5.2+x)) and certain temperatures. Here http://onsager.bd.psu.edu/~jir cit ano/phaseco2.jpg is what is called a phase diagram. If you want to read it, it would have to be marked. The "y" part would be in atm ("atmospheres" == pressure) and the "x" would be in temperature (deg C). Pick a pressure and temperature. find where the lines meet, if it's red, the substance would be a solid at that pressure and temperature. If it's blue, a liquid. Yellow, a gas. If you look, you'll see that for all temps at 1atm, CO2 will only exist as a gas or a solid. So, since Mars would have a much lower atmospheric pressure than earth, it's likely to only be found as a solid or gas on mars, too.
Actually, I found this http://www.timesofindia.com/04080 0/0 4hlth1.htm article with a search at Google. Neato!

ls output from publicfile's ftpd
publicfile is a fabulous package that should really get much more recognition and use. It can do 90% of what most people want from httpd/ftpd servers in a faster and far more secure manner.
However, one stumbling block for a lot of people is Dan Bernstein's exclusive use of his EPLF format for LIST and NLST requests. This format is a great idea but still isn't very widely implemented by ftp clients including most web browsers; this is why you'll usually just see the raw eplf output on most clients when you do a dir or ls (example eplf output).
I wrote a patch to publicfile that will cause it to use the more widely accepted /bin/ls format. This will allow it to display properly in most ftp clients and web browsers (example of patched publicfile ftpd, over 65k modem BTW).
The patch is at ftp://ftp.essc.psu.ed u/pub/emsei/woods/publicfile_no_eplf.patch. I don't believe it compromises the security of the package in any way. Please let me know if you find it useful, or have any suggestsions.

Re:This is nice, but when will they drop a camera.
Too true. At a fraction of the cost of most national welfare or medical programs, we find out more about how the universe works, and get awesome technological spin-offs. And if eye-candy can help provide that, all the better. Scientists traditionally are weak on promoting the benefits of technology, but we should be able to provide lowest-common-denominator type material for the masses.
As for the benefits, let's see: satellites (communication, weather forecasting, environmental work, GPS), and quartz watches to name a few. For an economists persepctive, try a 43% rate of return on investments in Nasa up to 1975 (not sure if they mean cumulative, annual, or compounded annual. At 43%, who really cares).
It would be nice to generate excitement in science, and help drive more young people into a science-based career (as well as having more science jobs out there). Exploring the limits of our solar system and reaching into space are a great way of doing this.

I would tell, but government will kill me.
The truth about gravity is very interesting. However, my knowledge cannot be passed on to you because my life holds greater value than the dissemination of this info (from my point of view). I apologize for my selfishness, but must point out that this what society has taught me.
Search here. -
This is just phase velocity vs. group velocity.
The experiments dress it up to make it look like something more interesting is going on, but really that's all it is. Math here. Animation here.

Re: Apps for which Linux is superiorSimply to make the record complete:
Pretty much anything related to software development. I mean you get a free (high quality) optimizing compiler, debugger, a whole load of libraries, etc.
You can download MPW for free from Apple's web site: debuggers, libraries, and the compilers used to build Mac OS and the ROM, which I guess is high-quality enough for Apple (although Mac OS X does use gcc).Network servers. I hope I don't need to say any more about that.
Well, you might mention that the first HTTP server outside CERN was written for the Mac, as is the one currently used by the US Army's main web site.Remote access. I can log into my computer at work from home, and do everything I could do if I was actually sitting in my office!
Me too! Timbuktu (commercial) or VNC (open source).Mathematical typesetting. Nothing beats TeX and LaTeX when it comes to this. Sure, there's TeX for Macs, but (AFAIK) you have to buy it.
OK, you got me: according to this page, the five versions of TeX available for the Mac are either commercial or shareware (as low as US$30).I admit that if I was building a system purely for free software development or as a network server, I wouldn't think of the Mac first. However, I don't think these are the kind of "applications" the original author had in mind (except maybe mathematical typesetting).

Writing summaries...
To a certain extend, I do see your point. Alot of what I posted is indeed in the article. Next time I will try to add alot more additional info.
Perhaps I should have noted some of the interesting research being done on this:
Physical Limits of Portable Power Storage
Hybrid Electric Vehicle research
In my defense, I do think I pointed out several things that were not obvious (and people were arguing about in the preceeding posts).
I'll try for more content in the future.
