Sometimes they don't have a choice. At least when it comes to features they don't want. Recently I went to get a new cell phone, and I found out that all Best Buy and my service provider offer are phones piled high with "features." My only requirement was that it gets decent reception, and it's a flip phone (so I don't scratch the screen to hell when I put it in my pocket with my keys), and the only phones that met this description are $250 phones with color and cameras. I don't really care about these features, (I already have a digital camera), to me, it's just more stuff to break.
Actually, it would be longer than 190 days. The rate of the leak changes logarithmically, not linearly. The driving force for the leak (the pressure pushing the air out) is decreasing, and as it does, so will the rate of the leak. It's the same principle as punching a hole in the bottom of a bucket filled with water, and watching the water stream get slower and shorter.
Working it out, it should be a little over 260 days.
Okay, I'm trying to figure out how this works...I figure from "Opitcal," they mean that the location sensor works very simuliar to optical mice. But, can anyone figure out how it puts the ink on the page? Is it like an inkjet that sprays ink on the page, or something like the old dot matrix printers, where's there's actually contact with the paper to put the ink on the page, or perhaps more like laser printers, or perhaps something completely different. I need two: One to take apart and figure out how it works, and one to play with. I wonder what the ink capacity of somethign that small would be...
I can just see it now, instead of seeing RO + EC 4 EVR spraypainted on bridges, we'll see some photo "printed" onto whatever surface of his choice.... could be, uh, intersting?
I think what you're refering to is the Atomic Force Microscope. There's a couple different methods of opperation, but essentially there is an atomic scale probe or needle that floats above the individual atoms. It floats because of atomic repulsion. At the atomic level, the idea of "touching" an atom becomes fuzzy. However, using this method, the atoms look like hard spheres, which is consistant with the way they are often viewed and thought about. Thus, the probe can map the countor of surfaces down to the atomic scale. So, essentially, what you get is a sort of topographic map of the surface. However, that is not a "printer." It's more of a reader, the same way you would scan an object significantly larger in size, such as a photo or a bar code. Just because you can display it on a screen, or recreate the image, doesn't mean the original reader was a "printer."
Try using a Beowulf-style cluster for a CFD problem, and watch as all computation grinds to a halt as your processors and interconnects devote all their capacity to inter-node coherency and synchronization.
Not true.. I admin a 52 proc Athlon 2100+ Beowulf style cluster that runs primarly 3-D CFD code. The code uses Fortran and MPI, and does FFTs across two of the dimensions, requiring huge amounts of communication. We use a Myrinet backbone which gets some impressive stats. Since the MPI is the only thing that uses the Myrinet (NFS uses standard ethernet), its difficult to saturate the switch before maxing out the capabilities of the machines.
Sure, you can probably get an SGI machine that processor for processor will out perform this machine, but in research, cost is the bottom line. The entire cluster only costed ~$85,000. That's only about $1600/processor. That's with 2.5 TB of total useful storage and over 40GB of memory. On a $/MFlop basis, SGI can't come anywhere near that.
...it just seems to be very hypocritical to me. I hate the fact that the **AA uses its seemingly infinite legal budget to stab at broke college students and and all the other users of P2P. At my school, recently the MPAA wanted to have the University kick the student out of school for sharing a copy of Austin Powers. I think that is a bit obsurd.
The advocates complain that every new step in technology, the hackers (crackers) will be there to break and abuse it. The problem is as long as the steps continue to limit the features that people can use, people will revolt and just find a way around the new restrictions. Anytime you assume you are smarter than someone else, you will always eventually find an instance that you're wrong.
That being said, if people are going to use "illegal" methods to crack their software, I don't see why they can do as much as possible to make it harder for them. The only people that are being hurt by a fake song on KaZaa are the people that are attempting to steal that song. (Okay, sure, you can say you're going to get a "back-up copy of a song that you own... Sure, that's what everyone is doing.... In that case, rip it yourself). Thus, you can't say "Heeey, the RIAA is making it harder for me to steal songs." Either you foot the money, or find a way to filter out the bad songs (checksums?)
Anyway, how long can it be before the bands realize that they don't have to deal with the crap from the record companies. They get into a contract where the get $.50 (or less) on an album that is sold for $18. Sooner or later, they'll realize the record compainies are the enemy there... not the people who actually like the music.
Broadband access and 2 XGA projectors, and a fairly decent sound system. It's like watching them on an 85 inch TV!
It almost makes up for having to work on a Saturday.

Apparently the size of other people's brains.
