I'll second what ultranova said - that positive pressure ventilation keeps the dust out. It's even used in instruments inside clean rooms - after probing wafers, we put them inside a small case (1 foot x 1 foot x 4 feet tall) that is even cleaner than the room (already a class 100 room - everyone in bunny suits, but no breathing apparatus)
But, mostly, entrance and exit are done with a double-door system. Open the first door, step in, close it. Then the timers activate the blowers and dust is removed from your suit. Then the inner door unlocks and you go in, freshly dusted off. There is an interlock that prevents both doors from opening at the same time.
I dated a race walker and knew a few of the top race walkers in the US. One of them was racing in DC, and the section of the course went around a golf course... and my friend got knocked in the head with a stray golf ball. Is that not excitement?! You never see that in the NFL, much less the x-games. About the only sport that happens in is golf, which is, of course, boring to watch.
If you want to get technical, Virginia doesn't call itself a state -- it's a commonwealth. The US has three other commonwealths - Massachusetts, Pennsylvania, and Kentucky.
They only used words from the English Ispell word list. Besides the english-language bias, this is probably limited in other ways. News websites use a limited vocabulary, but a lot of proper names -- so if one engine indexed these better, they wouldn't necessarily get a better rating. News sites are also very dynamic and have a large number of webpages, so they would be influential in the count.
Even if the feds can't tell what you're saying, they can still tell who you're saying it to. That guy in the coffeeshop that was sharing his itunes over an encrypted connection* -- better hope he's not accused of a crime?

Someone may come out with a patch, but don't you think they'd rather be spending their time writing games instead of fixing MS's purposely broken OS? And, as soon as they fix it, MS will just break it again in a different way.
Re: It always seemed a little silly to me that anyone even without so much as a valid logon could change the content of these pages.
I think the low barrier to entry is something that really helps wikipedia. I've often added information to subjects that I look up. For example, I was curious what years Mork & Mindy ran on TV because I now live near where it was filmed. I happened to know where the original house was located, but it wasn't in the entry... 30 seconds later and it was. Get a little info, give a little info - it's a good trade. I don't like to register even when all the information is for my benefit (e.g. NY Times), so I think even fewer people would register to help out a site.
Check out this thread -- Corscaria has a command-line program that uses libusb, so it's compatible with mac, linux, and windows.
I developed the unlocking code & did it on the mac. The Mac's user-land usb code is much easier to use than Window's (mainly because I don't need to create & install a specialized driver).
This is the third camera from the same company that I've reverse engineered and made reusable. So far, no lawsuit. While I wouldn't want a lawsuit, I think this would be an excellent test case for a few reasons: - Numero uno, I am not breaking the DMCA. Hopefully people only sue when a law is violated, but, sadly, that's not always the case. - I am accessing my own pictures, to which I have the copyright. The DMCA only protects rights-owners (me). - I am reverse-engineering for interoperability, which is permitted. Some judges think this only applies to personal computers and not "other" computers (like printer controllers, like in the Lexmark case) -- but I'm interfacing to a plain old PC. - Cameras have direct parallels to the "analog world". People have been developing kodak film with fuji chemicals for ages. It's a case that judges and juries can understand. - The courts have found for the defendants even in much less clear-cut cases (like Lexmark).
One very good trick Pure Digital has that keeps people out of their cameras is changing the architecture. The three cameras have had 3 different processors (8051, 8-bit RISC, MIPS), 3 kinds of toolsets (one big program, mini-OS, and full-blown embedded OS), and 3 IP vendors. This means the work I don on one camera doesn't apply to the next one... and will eventually tire me out -- it's a lot of work to do, and it takes them less effort to modify an existing camera than it does me to unlock it.
If no crime was committed, wouldn't that be all the more reason the reporter should protect their source? In other words, If there wasn't a crime, then why make them testify? Respectfully speaking, I think you have it backwards.
Bah! Obviously you haven't tried strace and ltrace yet. It like "process explorer" on steroids. With a big robotic claw. And super mystical monkey powers.:) It'll show file handles, individual read/writes, mallocs... anything that requires a system or library call (even strcpy!).
I thought CAPTCHAs would be pretty effective, until I heard of this cool scheme to get around them:
1. Spammer X wants to sign up for 100 free email accounts at free-accounts-Y. 2. Spammer X has a small cache of porn. 3. Spammer X puts up a website to allow access to his porn & promotes it 4. To see Spammer X's porn, Joe Average must sign up at Spammer X's website. 5. Signing up involves, you-guessed-it, a CAPTCHA! 5a. Joe requests to sign up 5b. Spammer X requests an account at free-accounts-Y and gets a CAPTCHA request. 5c. Spammer X presents this same request on their website to Joe 5d. Joe solves the CAPTCHA and returns the info to Spammer X 5e. Spammer X passes that info to free-accounts-Y 6. Repeat steps 5a-5e for lots of Joes. Result: lots of email accounts for Spammer X.
As long as the CAPTCHA is not impossible, people will process them for you for almost free.
yep yep! My machine language routine printed one line at a variable horizontal magnification. The applesoft portion called this and controlled the vertical scale (using floating point)
back in the day, I wrote a first-cut at a graphics dump program for the Apple II. The screen data was stored in bytes horizontally, and the printer wanted bytes stored vertically. Instead of doing the translation, I printed a whole screen line with just one pin of the printer. Then I'd move the paper up 1/144" and print the next scan line. It was 1/8th the speed of other dump programs, but it worked.
It turns out that the pin I used was the bottom pin. That's the one that the printer used only for descenders, like in "g" and "y". It turns out this pin started to fail after printing only a few sheets of dark graphics! So, my high school reports started having random misfires in some of my lower case letters.
I've been working a project that uses the MIPS-I compatible Lexra 4180, and in my research I found they were basically sued out of business by MIPS for creating a clone. This link -- the Lexra story -- is a good summary. From that article: MIPS Technologies claimed that because an exception handler could be created to emulate the function of unaligned loads and stores in software with many other instructions Lexra's processors infringed the patent. It was claimed to basically be a patent infringement case because the instruction set used the patented unaligned load feature. (I just coded this into my mips disassembler -- it takes two instructions to process, but the benefit is that it looks like it would be much easier to implement in hardware)
Nothing. They are in different areas of business, so there is no confusion. Trademarks apply only to specific areas of business and can overlap as long as the businesses don't.
It's been a long time, so I might not have the details right.
The robot travels on a grid and turns only 90 degrees. At each grid intersection, there can be zero, one, or more "beepers". Karel can detect if there is at least one beeper where he is standing. He can pick them up and drop them. The beepers are the only forms of variables, so it is very much like a 2D turing machine. (The beepers turn out to be pretty much the input and output of programs, unless you count karel's position). There are also walls, which karel can detect but not modify (or go through).
It's one way to teach recursive programming that is easier to understand. I learned it in high school, after basic, assembly, and pascal, but before pascal (again) and c and assembly (again). Guess I didn't fit into their standard curriculum flow:-)
That sounded good, but then I realized that government produced porn would probably include only government employees. The lady at the DMV, the lunch lady, Richard Nixon, my dad -- all government employees. *shiver*
I spent about 2 hours getting the pictures out, which was helped out by the fact that I had the right hardware and software laying around. But, the goal of that wasn't really to get my pictures. It was to get the firmware to analyze (mission accomplished) and to determine the format of the pictures (also accomplished). Yea, if I advocated this just to get pictures, then I'd agree that was a little excessive.
Also, yesterday I got the flash re-installed into the camera and it still works.
BTW: agree with grandparent's sig, too. I was watching the movie and kept thinking "ug, this is bad, but not as bad as Ep II"

Good point. Accidently delete or overwrite a file on a RAID array, and it's still just as hard to recover as if it were on a single drive.
Someone did!

good thing it's not written in "karel the robot", a simplified logo-like language. That language has no turn right command, so you have to define it as three 90 degree left turns.
Your idea sounds like this -- except for the help function.
The Orion Multisystem (96 processors under your desk) and the OQO are recent examples. They are in some Sharp notebooks ... browse the list here.
