Yeah, and who are you going to complain to when that old machine dies? There's a reason Cisco can charge so much for their routers: the things are extremely reliable and work extremely well. An old Linux box is not going to hold a candle to either performance or reliability. Besides, Cisco's prices are significant only if your company is extremely poor. Paying $10k for a router that you know will last a decade or more and not fail is not that bad a deal. Yeah, you can save a few bucks by repurposing a PC, but you'll lose a lot more than the price difference when that thing dies.
Conspiring with another company to lock out a competitor is anticompetitive and illegal. That's called a trust, and that's what antitrust laws were for.
The question is not whether anyone cares about Skype conference calling. I doubt anyone uses that feature. The financial damage incurred by AMD from this is more along the lines of lost consumer confidence. If Intel can pay software manufacturers to restrict their software to run only on Intel chips, they can do a lot of damage to AMD. Hence, AMD cannot allow this to happen.
I fail to see how the Berne convention forces Russia to require charging 99 cents for downloads. There is quite a bit of latitude in how copyright laws are actually implemented. And you haven't provided a shred of evidence that allofmp3.com is illegal in Russia. It's not like it's some kind of fly-by-night business; they have their street address, registration numbers, and even bank account numbers posted on their website. You can get a court order in Russia just as easily as in the US, so that's not the issue here.
Also, this is kind of a grey area of the law. However, copyright regulates copying. If you purchased something legally outside US jurisdiction, I fail to see how you can be violating US copyright laws by importing it. You may be violating customs regulations or something like that, but I don't think the recording industry can do much about that.
The grey area comes from the fact that the copying is done digitally, over the internet, and it's hard to establish jurisdiction. But then, ripping your own CDs to your iPod is just as much of a gray area -- neither the law nor the recording companies explicitly authorize it, and it doesn't fall under fair use since it's not exactly a backup copy.
You do realize that there are other webservers besides IIS? And that many programs have their own web server built in? And that a custom DVR box probably doesn't use expensive enterprise software?
Read a book about networking. The linksys will drop the packet unless it either matches a NAT record or it is going to one of the forwarded ports. Last I checked, there are no network stack vulnerabilities in Windows (or any other system, for that matter). All known worms target Windows services running on other ports.
OK, so you have two ports. I assume viruses aren't getting in through those, since they are serviced by Pelco's own software which has presumably not been targeted by viruses. Put a cheap NAT box (like a $30 linksys wired router) in front of each machine, and forward ports 80 and 9999. That will solve all your virus problems, since Windows viruses can't infect Linksys boxes.
Look for small companies, they might be VERY willing to pay a smallish salary to someone who can fix up their webpage or maintain their computers. These jobs are very easy to find, and there are lots of them. Just look around town and ask random local business owners, you'll probably find something.
Is it really that hard to understand that copyright laws in other countries can be substantially different? Here's another example: textbooks that cost $150 in the US cost $10 in India. Not to mention, there are several dozen competitors to allofmp3.com, none of which have ever been sued.
I don't think anyone is stupid enough to claim that heating causes cancer. A phone would have to put out at least 50 watts to cause noticeable heating. Not to mention, the sun shining on your head causes a lot more heating.
As far as peak-to-average, it's always very important. Average power through a resistor might be very low, but it will still burn up if peak dissipation is too high. Similarly, sticking your hand in boiling water for 2 seconds isn't a very large amount of heating if averaged over an hour, but it will still burn your hand pretty bad.
Neither of these four will have the same absorption or interaction in the same parts of the body as 2450 MHz (wi-fi).
There is nothing special about 2450 MHz, and it's not significantly different from 1900MHz. The properties are almost identical.
A more reasonable value to calculate is the average power at the location of the person.
Sure, calculate it. I can tell you right now that cellphones and wireless cards need the same minimum signal strength to receive the signal properly. Which means that being within 10 feet of a router with a 100ft range is roughly the same as being within 1 mile of a tower with a 10 mile range.
Typically people sit right next to wireless cards and routers, while usually very few people have lunch right beside a cell phone tower.
Typically, cellphone towers transmit at hundreds of watts while access points only put out maybe 100 milliwatts. It's kind of a big difference, you see? Not to mention, a cellphone can easily put out 2-3 watts, right next to your brain.
And even then, it's more biologically relevant to consider the power absorbed at that wavelength in a localized portion of the body, rather than trying to average over the entire body (which, if you'll note, is not a homogeneous substance).
The body is mostly homogenous and mostly consists of water. And I'm not sure what the hell your point is.
You know, there is a science called statistics. And statistics can tell you how many households you need to get a certain margin of error for your measurement. As long as the households are randomly selected (not too hard to do), it's accurate to a percent or so even with a smallish sample.
The artist may not get any money even if you buy the CD. The money goes to the recording company, not to the artist. How much money the artist gets is determined by their agreement with the publisher, not how much you bought the track for. I really doubt any significant amount of money from iTunes goes to the artists, either. Recording studios are really good at finding loopholes, too -- note how much they whine about how iTunes is not expensive enough.
Yeah, the process definitely needs work in gEDA. However, it is also easy to automate this stuff in gEDA. It's a lot easier to edit a text file to change pin numbers for a component than it is to deal with Eagle's library editor. Not to mention, try creating a surface mount footprint for a 208-pin chip in Eagle. It is next to impossible. In PCB, all you have to do is write a few lines of code to generate it for you. And this is hobbyist-level stuff. The professionals these days have to deal with multiple 1500-pin microBGAs on 24-layer boards.
The professional tools are anything but user-friendly. They often have lots of bugs, poor documentation, very strange ways to do things, and an interface straight from Windows 3.11. Not to mention a ridiculously high price. The reason people use them is because they are also very powerful and get the job done fast. They very rarely have good libraries, because every company creates their own libraries to their own standards and manufacturing requirements. The reason you think it's important to have good libraries is because it's such a huge pain to create them in Eagle. If I remember right, Eagle doesn't even have the ability to generate an array of pins. I suppose you could write a utility in their scripting language to do that, but that's a very basic feature that should be built in.
Well, I think the Cadence stuff is something like $20k to $30k per seat, and possibly more. I'm not entirely sure, but that's the numbers I heard thrown around at work. Plus the maintenance fees and such. I'm pretty sure Protel is quite a bit cheaper. The two main high-end PCB layout products are from Cadence and Mentor. The low-end products are quite suitable for many companies, namely the ones that either have simple designs or not many products. However, if you need to layout complex multilayer boards with high complexity, you will need high-end software. Of course, it's amazing how expensive product development can get: a single large PCB with lots of layers and a short lead time can cost upwards of $30k to manufacture. So yeah, there is a huge difference in how much different companies are willing to pay for software.
It has never crashed on me either, which is more than I can say of most other CAD programs. The Orcad stuff is especially prone to crashing. The main thing that pisses me off with Eagle is the interface. They STILL don't have markers on unconnected schematic pins, and it's still really easy to miss connections. The graphics engine loves to leave boogers. I'm not a huge fan of integrating schematics and board layout together. The PCB tool is primitive and has major problems. Just try moving a component. There are often invisible bits of traces left that get dragged out and you have to delete manually. Of course, if you aren't careful, you will unroute the whole net. Usually, an hour of using Eagle to do PCB layout is enough to elicit many four-letter words. There are lots of subtle bugs in there that have been there for so long that they have almost become features. It seems the developers are content with mediocrity.
Well, Protel is a crappy entry-level package as well. I liked it more than Eagle, but it definitely is far from perfect. The thing that gets me in both of them is the amount of work you have to do just to move a component or shove some traces around. With Eagle, it's almost always easier to just start over, especially if it's a dense surface-mount design with lots of short segments. Once you try Allegro with its interactive routing, you will never want to go back to doing it the hard way.
With that said, I think autorouters are mostly a gimmick. I suppose they can be useful if you have an 8 layer board and 1000-pin components AND it's something like SPECCTRA where you can specify signal integrity constraints. Anything less than that is just useless and usually results in a suboptimally routed board. In my experience, autorouters are especially bad on 2-layer boards, since they can rarely route them successfully and you end up with a board that's impossible to finish without starting over.
Bleh. The Eagle autorouter is next to worthless. It can't do autoplacing, and it's not very smart. Unless all your boards consist of less than 10 through-hole parts, it generally can't route them worth a damn. Real autorouters cost a lot of money for a good reason. The one built into Eagle is a toy.
I like the PCB program. It integrates well with gschem (much better than how Eagle does it). It's a lot less buggy than Eagle (no annoying boogers and redraw bugs). It resembles a professional PCB layout tool a lot more than Eagle does. With a bit more work, it could easily compete with Protel.
Bad idea, unless you don't mind redesigning the board if you want to use a different manufacturer. ExpressPCB locks up your data in their proprietary format. Be aware of that before you design your boards in their software.
Well, $400 is rather expensive for a product as shitty as Eagle. That program sucks, big-time. More than anything, it resembles Autotrax for Mac, circa 1986, but with more bugs. Anyone using this program for anything serious is insane; it is at best a hobby-grade product. If you actually have to pay an employee to use that program, you would save money by purchasing a real PCB layout tool.
Besides, if money is no object, commercial solutions almost always win. Would I rather use Solid Edge or some crappy open-source AutoCAD knockoff? Would I rather use Cadence Allegro or a cheap/free PCB layout program? There are very few open-source projects which are actually superior to their commercial counterparts. In most cases, people use open-source software because they can't afford the real thing. I fail to see how that is bad.
Subthermal levels of radiation can still affect the biological function of polar molecules, which can in turn can cause carcinogenic compounds to end up where they don't belong.
Like the OP said: if you can demonstrate this, you would get a Nobel prize. So far, there is no way of interaction which can screw up DNA molecules by anything other than heating. Not to mention, if this was true, the cancer rate should have went up like 1000000% between 1995 and 2005, when cellphones became popular.
Uh, wi-fi signals ARE radio waves. As are cellphone signals and so on. They are not the same wavelength as broadcast FM radio, but they are roughly the same wavelength as cellphones and cellphone towers (which are all over the place and have a hell of a lot more power than any wi-fi transmitter).

What makes you think he is running IIS? It sounds like software from the camera manufacturer to me, and it's not susceptible to IIS exploits.
