Your math is off twice. 70,000 / 365 is 200, not 2,000, which doesn't really matter because:
70,000,000 *.01% is 7,000 searches per year, not 70,000. So it would still be about 20 per day. They already do more random searches per day than this.
This is a topic that can be very difficult to grasp. There are multiple semester courses in Fourier analysis in college. I'll try to make this as simple as possible.
It is easier to explain with sound first. Imagine how a recording of your voice looks, when converted to an image of a sound wave. This waveform has peaks and valleys. If we take a triangle wave (/\/\/\/ ) we can see that it almost looks like a sine wave. We can, in fact, convert the triangle wave into a summation of cosine waves. The main cosine wave has a frequency equal to the frequency of the triangle wave. We can then add a second, higher frequency cosine wave to the first, and this helps our waveform fit the triangle waveform better. We can continue with higher and higher frequencies until we have an almost exact representation. Corners in sound waves are very high frequency transitions, because the wave direction is changing very fast. This is why a 44.1kHz waveform sounds much better than an 8kHz waveform. Higher frequencies can be represented when the samples are converted into cosine waves to be played back. Thus, the frequency is like the detail of the sound.
Frequency, when related to an image, is like the detail in an image. The frequency, in this case, is the frequency of the cosines used to represent this image. The cosines in a 2-d image can be imagined as taking the height of the cosine as the brightness value. The lowest value is black, and the brightest value is white. Imagine we have vertical bars of gradients from black to white. Higher frequency cosines will result in more bars in the image. These bars can be in the X (horizontal) or Y (vertical) direction. We can add these bars together and create an image.
The basis of the fourier transform is to take an image, and convert it into this cosine representation. If we do this, we then have a list of the frequency of the cosines in the X and Y directions.
Going back to the detail in an image: If we remove the higher frequency cosine waves, and convert the remaining data back into an image, we get a blurred version of the original image. This is the basis for many of the image filters in programs like Photoshop.
The company is cheap. There's about 50 computers / 150 employees and they do anything they can to save a buck. Sadly, I've tried explaining to them that they're making bad decisions, but the VP and President don't want to listen to a 21-year-old college student telling them about decisions. One main problem is our windows licenses. They decided to get OEM licenses with beige-box homebuilt computers. One of the engineers' sons put them together. When we've had to reinstall, sometimes the licenses refuse to activate and I get stuck having to deal with a call to MS Tech Support to fix whatever the problem was. And, they went cheap as possible on the computers as well, so, we have hardware problems such as bad memory chips, bad motherboards, and other things. My boss has her networking degree, and is MS certified in something, but as I stated earlier, she comes to me with questions about how to do things on the system. I know it's sad, but with what my company is willing to do it is in the best state it can be. I try to clean up the messes other people make and document everything I do so that my boss or my replacement can understand the Active Directory groups that are set-up to do automatic mapping of drives, printers, and other network resources at login if changes ever have to be made. As it is, things are running smoothly and my boss understands the AD system as it is set up, so since the company is small and the servers are working, the setup probably won't change at all for around 10 years until they bring in consultants to do the next network and server upgrade. Maybe they will leave better documentation on the systems in the future, rather than just saying "AD is easy, you just do this to add a user or group. Bye!"
I moved from being an Excel junkie to being a network administrator with 5 servers. I had not used Active Directory or Windows Server 2003 before this point, so it was all new to me. My boss knows less than I do, and the people who installed the equipment basically showed us how to set up a new user when it was necessary. Nobody told us how to map home folders, shared network drives, printers, set file permissions, or anything else. Everything I know was learned on my own, however, it was all researched on company time. They've been pleased with the system so far. It's not too hard to learn.
Business problems come from the companies writing software for Windows. For example, at my work, auto update is turned off so that Service Pack 2 will not install. This is necessary because it breaks our old CRM software (Open Systems Accounting Software). The new system we are migrating to (Epicor Vantage) uses Crystal Reports, and it doesn't work right with Service Pack 2 either, and the support people tell us that they don't support Crystal Reports on SP2.
I think that what the parent is trying to say is that using the same volume setting on the iPod, the current will be lower with a higher impedence set of headphones. The sound output is theoretically lower, because the bigger drivers in the speakers need more power to cause them to vibrate and produce sound.
There is a quote spreadsheet at my work that I have had the unfortunate task of dealing with. There are 14 tabs of information on it, many dealing with displaying the same information in different forms (cover sheet, billing sheet, materials sheet, build sheet, etc.) and there are multiple ODBC queries and links to other (some non-existant) spreadsheets. Every quote that is generated is saved as its own file based on the part number being built and the customer. There are approximately 3500 different quotes that have been generated over the years. My task was to pull certain fields of information off of different tabs in each of these Excel files and combine it all into a master "database" of information - once again in an Excel spreadsheet. The problem is that the data and presentation are not separate and the format of forms has changed over the years, so information is not in the same place on all of the files. I managed to do it in a couple weeks' time using VBA macros in Excel. My pleas for a database solution went unheard.
One time I forced a database upon my management, and they still refuse to use databases for any new projects even after seeing some of the benefits of keeping the data and presentation separate. Keeping track of all the IT assets has been easier, though. When they asked for labels for all of the computers stating what the system specs of each machine were, they could be printed in less than 5 minutes, which was mostly spent designing the form to print the labels.
My brother had an incident of identity theft which happened through the mail. A gang drove around and picked up envelopes containing payment for bills and had checks printed using the correct checking account information. They even printed drivers licenses with their own picture and changed the birthdate to about 10 years older than my brother's age. He caught the unauthorized activity by chance when he deposited a check at the bank and they told him he had a negative balance. Around $480 of unauthorized activity had taken place. They froze the account at that moment, he went and filed a police report, and the bank canceled payment of all of the fraudulent items. He received calls and letters for months saying he had written bad checks and that he would have a warrent put out for his arrest if he did not pay. He had to mail dozens of copies of the police report and a copy of the notarized statement he made saying he did not write the checks or authorize electronic payment of the items purchased on the internet. The postage totaled about $30. The money from his account was eventually all returned to him, but all of the time spent on the phone with companies trying to get the issue straightened out is a huge hassle, and the money for postage and telephone calls to various out-of-state companies comes out of your own pocket.
I meant it is strange that the owners of all of the networks in my neighborhood have enough sense to set up the encryption on their networks. For example, my friend's dad is not especially skilled at computers, and he set up his network himself and had enough sense to know that other people would be able to access his network share through the wireless connection. This was before the local news coverage about open access points, which has probably helped some other people know the risks of running an unsecured wireless AP.
In my neighborhood, there is a MiddleEarth, linksys, and a friend's dad has one called BatNetwork (he is obsessed with Batman). The strange thing is they all have WEP or WPA enabled, including the linksys.
Sometimes there are problems accessing the site. It says that the server is too busy and doesn't let you log on. Usually you can try again and it will work after a minute or two, but a couple of times I have had to wait an hour or so and it would work then.
If you do give it a try, I'd recommend you use their explorer program if you can, since it manages downloads much better than going through their website, and downloads seem to run a lot faster through that also.
I have used the allofmp3 website. I sent them payments of $5, or 500MB worth of data, two separate times (they showed up as about $5.04 on the statement, I'm guessing it's something with the conversion rate). The first one was back in August, and there haven't been any odd charges on my credit card so I think it's probably safe. They are doubling their prices in the middle of January though, everything will be 2 cents per MB. I've been able to get a few things from there that I can't find at the stores in MN.
Who wants to watch a bunch of geeks working at their computers? Everyone knows only geeks know how to run webcams. Unless the virus writers set up webcams as a service for sorority girls on the side...
I'm studying electrical engineering at the University of Minnesota, and at that school everybody is required to take liberal arts courses. There are certain minimum requirements for history, language, science, arts, etc. There are something like 20 requirements that students need to complete throughout their degree program by taking liberal arts courses. The school's reasoning is that people need at least a background knowledge in other topics besides what they are studying for their degree.
My neighbor designed and built the original of these. He builds RC airplanes and helicopters, and he had the idea for an RC spaceship, and that is basically the design he came up with. He ended up selling his design to a company. He still has his original prototype, and sometimes I see him crashing it off his roof in attempts to make it slide down the shingles.
I hope they plan on releasing higher bitrate demos of music if they want to show this as a new format, because most mp3 music sounds bad even at 128 kbps, let alone 64 kbps.
