    It's interesting to me that over the millions of years of evolution life has gone through, we're still using the same basic outlines for anatomy.

    The reason we think this is because of our perspective. Stand back and look and then it's different. Live has existed on earth for maybe 4 billion years. Dinosaurs lived 160 million years ago. 160 million yeas is only four percent of the total time life has existed on Earth.

    "College is a means to an end....and while it is nice to learn other things to be a bit well rounded, that is extra fluff if you have the time and money for it while there, but, don't forget the real reason for going."

    "College" is a general term that can mean a university or a trade school or a Comunity College. Basically learning a programming language is something that should be covered in a trade school or two year community collage. If all you want to do is write the back end to some web site go the trade school route and learn all about 2008 vintage technology.

    A computer science student at a university should be learning "computer science" not 2008 vintage technology. The importent stuff that you need to know will let you do more then just right small programs. You should be lerning some theory that will remain valid for decades. Kind of like what a math major learns -- stuff that will remain valid in 2108.

    Where I went to school I think they did it right but then back then a CS major was almost an "independent studies major" and we were able to adapt the program to each student. My faculty adviser would load me some of his books and we'd make up some assignments and we'd talk every week about my projects. (Hard to make that system work in a 30,000 student public university.)

    Bottom line: ALL university CS education is not screwed up. A lot of it maybe is. What save it is that to graduate the university requires that you have a rounded education that includes liberal arts and so on. and after four year of this ou learn how to think on your own. This last part is the most important thing they can teach.

    One could fly around the Earth even if it were flat. Image the flat earth layed out exactly as with any of the map projections where the entire Earth is drawn on a flat paper map. It is possable to fly in a circle (no, a "closed loop") such that you would see the same ground track as if you flew over a great circle route over a sperical Earth. I don't think you could tell the difference just be flying and looking out the window. One way to prove that it is round is to measure the local curvature. This is easy to do it the land is very flat or on water. All you do is stay in one place while you watch something slip over the horizon as it goes away from you. The horizon is only a few miles away. It does not take long. But this only proves a local curvature, like maybe a small hill. So you repete this experimant at many locations untill you find that the "hill" is 6,000 miles tall You could also fly to the moon and look at the Earth. But this is expensive. The above experiment was done in Eypt 4,000 years ago using just simple tools

  10. Build with bricks not wood on More Mac Vulnerabilities Than Windows In 2007? · · Score: 1

    I think we are comparing Apples to Oranges here. (Sorry could not resist) But it is true Apple counts ever small nt pick fix to every program. For example the recent Mac OS update listed about two dozen fixes. Microsoft lumps this kind of stuff all together and counts it as one fix. The other thing is "Who cares" what mattersis the final result: No one, or "hardly anyone" runs anti-virus or anti-spyware software on a Mac. It is simply not required. The fire wall is open by default too. It is not needed. So given the fact that most Macs have the firewall disabled and no anti-whatever can anyone point to even one Mac that have problems. I'm sure some did but the problem is very rare. On the other hand even with firewalls and anti-virus programs widely used we do hear now and then about eople having problems with Windows PCs. I would have thought that Microsoft as a company would be embarrassed that an anti-virus industry even exists. The fact that it does speaks volumes about Windows. People say it s only because Windows is the majority OS, so it is targeted. Hell no. Could you imagine the "bragging rights" a hacker could get if he was able to write a Mac OS virus that would spread in the wild? Believe me this is the Holly Grail and there is strong motivation. Use this analogy, do termites eat wood houses because most are made with wood and they leave brick houses alone because there are so few of them "so why bother?" No, the engineers who wrote Mac OS X, Solaris, BSD and Linux simply used bricks and avoided the whole termite problem. They built and OS that viruses can't live in.

They are there, no one but the dog can hear them but they are there and the mic picks them up not well but it picks up 33Khz. If this high frequency sound is able to make it's way to the digital converyer it will alias to an 11Khz signal and fall right into the band of human hearing. This is a hard problem to fix and in theory realy can never be fixed. Please re-read the wiki article. What it says is that they really do need to go to at least 96Khz sample rate and in fact "everyone" does. The studios all use 96KHz or higher and the player all oversample the CD.

All analog hardware is not perfect so violation of Nyquest is unaviodable with real-world equipment. http://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem#Aliasing Another way to look at aliasing is to think of the input analog signal (a singer's voice) as "beating" with the sample frequency.

The square wve has the 44Khz fundimental plus all the hormonics up to infinity. http://en.wikipedia.org/wiki/Beat_(acoustics) AM radio uses this.

    Nyquist's theorem states that you can accurately represent frequencies up to 1/2 the sampling rate. That is 100% true. But in the real world, if you are sampling a digital recorder at 44Khz how do you ensure that NOTHING above 22Khz gets to the analog to digital converter? You need a strong analog filter but there are no filters that have an exactly square cut off Maybe let's say you have a 24db per octave filter. This mens you will have only attenuated the higher frequencies, not eliminated them. Same on playback. You need a theoretically perfect analog filter to playback. Such analog filers do not exist. The way they get around all this is to sample at 96 or 128Khz. If you do this then real-world analog filters can be used.
