One is in the Normandy Shopping Center, near the Ledo's Pizza (formerly Giovanni's, I think). The Adult Video store is on the other side of 40 (the north-going side), Normandy Shopping Center, and the 2nd baang is up the road (closer to Baltimore) from it next to the Papa John's pizza. Look for white text on a green background in english ("PC-Game") and korean. One of them used to be next to the Burger King that is farther down rt. 40, away from Baltimore, but that whole building is getting emptied. There was the baang, and an auto glass shop, and a hair salon, and a golf shop, etc. Well, whatever. I hope those are OK directions.
I went once when they just opened, and it was $2/hr to start, but they said it would be $3/hr for the 1st hour after that. The rates go down the longer you stay.

"But what does RSN mean when they say their death is predicted RSN?"
RSN is generally translated as Real Soon Now. It is used occasionally when the event is in the future, but at an undefined time in the future. Asking when a software project was going to be completed, it could be answered with "Real Soon Now". This doesn't mean that the release date is definite, or that the release itself is definite either. Perhaps a good example for the term is AMD's Hammer processors, which were originally supposed to be released late 2001, then middle 2002, then end of 2002, and now, hopefully, we have them in mass production and distribution after April/March of 2003.

"Does anyone know why the korean word is being transliterated 'baang' with two 'A's? I don't remember it being anything other than a regular A sound in Korean."
While I don't know any korean (ok, a few characters and a few swear words) the two places near me (central MD, rt. 40) name themselves PC-Game in white letters on a green background, as well as the accompanying korean text. One of them does have "bang" and not "baang" on their store awning. (One of them inhabits the place that a christian bookstore once occupied, but the bookstore moved a few plots away, in the same shopping area.)
One thing that I found interesting was that both the stores sell manga and other books. I'm a little curious as to whether this is market-driven or ordinance-driven, as I remember a porn store (conveniently located on the opposite side of the street from above-mentioned christian bookstore) that started stocking a whole huge amount of old used books, in order to comply (or skirt) an ordinance about its products and the nearby housing developments (being within 1 mile of them or something). Erm... I only went into the porn store because the paper said they were closing... Yeah... That's plausible... Besides, it is easier to buy things online! Doh! Did I say that out loud?
".. then they'll have a beowulf cluster of case modded speak and spells. I hope I'm just being facetious but as someone else pointed out, they do seem to have a lot of time on their hands."
Actually, that isn't really such an outlandish idea.
Do a search for John Cage's "Imaginary Landscape #4" and then add in some computer-automation. This isn't really a very odd or unworkable idea. Hmmm....
"It seems to me that purchasing the Alpha would be a great deal for AMD. They are already in a position to design and manufacture it.
In addition, many still depend on the Alpha, and this would give AMD the server market it's always wanted, and has been trying to secure.
All this is not mentioning that the Alpha's perfomance has always been far better than x86. Just imagine what would happen if AMD came out with a 8GHz processor a year from now..."
I think the problem with this is that Intel bought most of the Alpha engineers, from Compaq, before HP bought Compaq (or however that deal worked...) so AMD would have to do some serious work to get those people. However, from my understanding (and I may be completely wrong) Hammer is basically a RISC CPU that does CISCy x86 stuff. While this isn't new (I think as far back as 286 or 386) this has been what the chips looked like, translating the CISC code into mo-betta RISC code for the CPU to run through.
While the RISC architechture of Hammer is exciting (and hopefully a little easier to program for), I think the more exciting prospect is that of HyperTransport and what it will mean for bandwidth inside the system (as well as allowing for 'glueless' multiprocessing). Then again, when I mention that I find HyperTransport more interesting than Hammer, most people get a certain look on their face, one that says "You... suck." But I'm still excited about it.:-)
I don't think the whole story is that there are fewer women taking computer science classes and going on to graduate with computer science degrees, but that the field as a whole is experiencing some drastic enrollment shortfalls. Face it, would you really want to go into a discipline that will put you into a position of being neglected, overworked, and possibly underpaid? It isn't that women are doing it less, everyone is doing it less. That, and the splitting of what-was-computer-science (some math courses and some electronics courses, bam, here's your degree) into 'modern computer science' and then into computer engineering, electrical engineering (with chipmaking, etc), computer science, information systems, and whatever else has cropped up in the past few years.
From what I've heard (and it is only from 2 schools), enrollment is declining overall for computer science. It just isn't happening. Think about right now, the economy is kinda crappy, and we've just come out of this bizarre greed-affair of stocks and internet millionaires that most people would really like to forget. It just isn't as sexy to the general population anymore.
I also wish to take issue about the gender equality statement, just because I can't seem to get it to make sense to me. Law? Medicine? We don't have recorded history long enough to find the origins of those professions. (I won't mention the profession of courtesan, oops, I did.) The fact that computer science and electronic information technologies are so young doesn't really make for a good comparison as to where the gender equality situation stands. Should we take a survey of modern-day sanitation workers? As someone else said, sterotypes are self-perpetuating/self-replicating.
OK, I'm done now. Yes, I am a CS student. Advice: get your prereq courses done at a community college and put the rest of the money in a CD or bond or something (CD, look it up, it's an investment vehicle).
While this is very interesting, is the speed of the propogation of gravity constant or can it be affected by certain conditions? This brings to mind the experiments at slowing down light in a special supercooled gel (is this an Einstein-Bose condensate?).
I don't think I like the idea of light being the fastest anything can travel, though. Perhaps it is for many things, but what happens if some forces travel at speeds faster (or multiples), or perhaps simple fractions, and we discount those readings instead of seeing if the old model can be adapted or remade? Well, many questions, few answers from me.
Does anyone remember the 'gravity shielding' story a while back, where a spinning superconductor was supposedly responsible for changes in weight? Podkletnov comes up in a google search for 'superconductor gravity shield' but I haven't heard anything further about it.
Also, what about magnetic forces? How do those work, and at what speed do they 'travel' ?
The question is whether you have gained the legal right to use the hardware and software, or whether you have just bought a license to it (the work is not owned by you, merely licensed for your use, and the license could be revoked at any time). Yes, the point that has been made many times before, but in case someone hasn't heard it...
"Isn't reverse engineering a company's hardware/cracking encryption a violation of the DMCA? I am not saying I support the DMCA but it would be a shame if unsuspecting people jumped on this project and had the FBI raid their house and throw them in jail."
Ah, here we go... US Code, Title 17 (copyrights), Section 1201 (part of the DMCA)
(reads it. reads it again.)
OK, I don't feel so smart anymore... But, the first part (a-1-A) of the section says:
"No person shall circumvent a technological measure that effectively controls access to a work protected under this title. The prohibition contained in the preceding sentence shall take effect at the end of the 2-year period beginning on the date of the enactment of this chapter."(This should be in effect now, since it was signed into law by Clinton in 1998)
but later in (f-1):
"Notwithstanding the provisions of subsection (a)(1)(A), a person who has lawfully obtained the right to use a copy of a computer program may circumvent a technological measure that effectively controls access to a particular portion of that program for the sole purpose of identifying and analyzing those elements of the program that are necessary to achieve interoperability of an independently created computer program with other programs, and that have not previously been readily available to the person engaging in the circumvention, to the extent any such acts of identification and analysis do not constitute infringement under this title."
Go read the whole thing (well, maybe it isn't recommended) but this *should* be legal... or... not. There is always the saying that if you cannot exercise a right, you don't have it. That was the tactic used with DVDs, even though you were allowed to make fair use copies, the use of CSS and Macrovision did not allow it to happen as easily. (No, I am not a lawyer.)

"Did you know FedEX has 610 [hofstra.edu] airplanes in its fleet already?
Now helicopter, *that* is a crazy idea for moving cargo..."
(insert me looking sheepish and semi-dumb) Yes, but how much cargo would you be putting on a drone? Still you are correct, and someone else pointed out rightly that if you can make a small drone not-crash, you could easily make a large previously-live-piloted aircraft into a drone and then make that craft not-crash.
I have to admit your correctness, espescially since I have a package from newegg.com that is winging its way across the country on one of those fed ex planes...
"Supporters envision the use of drones, also known as unmanned aerial vehicles, for such tasks as moving cargo, pinpointing traffic problems, patrolling the border, searching for fugitives or fighting forest fires..."
Moving cargo? unlikely. You'll put the cargo where, exactly? Use a truck, train, or other land-based vehicle. If not, use a helicopter. pinpointing traffic problems? Use a helicopter and overpass-mounted cameras instead. searching for fugitives? Eh... it helps to know where to search. An unlikely application. Fighting forest fires. Oh brother. I suppose this is a "do it for the children / spotted owls / cute trees" reason.
In short, too expensive, too unmaneuverable, too risky. We'll ignore all the creepy paranoid Skynet implications.
