My brother got one of these 150-in-one electronics kit when I was a kid (mid 80s).
It came with a thick book that had a one-page writeup of each circuit. I studied each one until I started to catch on. Then I went to the public library and read their (abysmal) selection of electronics books.
Now I have my MSEE and I can still remember some of the experiments. The perplexing explanations I now realize were wrong. The Internet has made getting answers and datasheets to almost anything possible.
To someone starting now, I would suggest an alternative. Get one of those white plug-in breadboards and a selection of discrete components. A place like Electronix Express sells this stuff and caters to the educational crowd. Get a multimeter too. Then get books. For general electronics, buy the Art of Electronics. For a gentler introduction, borrow "There are No Electrons" from the library. To stay interested, get a practical book in an area you are interested in, such as the ARRL handbook if you like radio, or a robotics book if that's what you like. Examine those circuits until you understand them. And find an Internet forum to ask questions about what you're learning. sci.electronics groups are good. I've found the PIClist to have excellent off-topic discussions about general electronics questions. It's pretty good for PIC microcontrollers as well.
(ignoring the fact that the program you mentioned above is NOT eligible for copyright protection because of its obviety, non-intellectual-novelty and other similar factors)
You are confusing copyright with patent protection.
Copyright covers an expression of ideas. No matter how old or lame those ideas might be.
Speaking as a former user of such a university computer, I was *glad* not to have root access on my machine. It removed the burden of system administration, and left me to concentrate on the stuff I was supposed to be working on.
UNIX permissions are designed for just this situation, allowing users to work freely without giving them ability to break the system. Why is the orginal poster trying to circumvent this?
Many ICs do not have specs available to just anyone. Try getting the detailed spec on certain Broadcom chipsets, for example. In fact, many times the chipset documentation is the card documentation. For example, look at how many Linux drivers are named after chipsets.
Far as I can tell though, most ICs are pretty standard and available.
Many ICs are also programmable. Reverse engineering their firmware is much harder than ringing out continuity on a PCB.
This month, I had two disk-failure on a 1.0 TB software raid5 with ReiserFS.
I was able to copy most of the data with dd_rescue and myrescue.
By the time I was finished mucking around, I had dome mkraid -f several times, so there were spots of missing data on the disk. The filesystem would not mount. So I used resierfsck --rebuild-tree, and once it completed five days later, I was able to mount the filesystem, with most of the files intact.
Between the VCR and the capture card, second deck, etc, make sure you use a time base corrector. Don't trust the TBC supposedly built in to the VCR or capture card, get an external unit. Otherwise, audio sync problems will haunt you forever.
The technology is called S.M.A.R.T. That stands for Some Stupid Cutesy Ancronym.
Fow UNIX, you want to use smartd, which is part of smartmontools
S.M.A.R.T. is pretty good at detecting normal failures. It is no help for when Windows decides to chkdsk your > 137GB partition and scribbles garbage all over the disk.
It's done very little to improve the quality of life for humans and quite a bit to degrade it.... it's nowhere near a necessity and if humans would tolerate a little discomfort, the Earth might be in much better shape.
Think about this the next time you're eating fresh food shipped on a refrigerated truck and stored in your refrigerator... If you'll allow that refrigeration an extension of air conditioning, it has had a vary big impact. on quality of life. Probably a measurable impact on lifespan, even.
Wouldn't the same arguments apply? In fact, PS is a programming language. Don Lancaster: "an unappreciated yet superb general purpose computing language"

Look, Cheeseburger Brown has already prophesied all of this.
I think they missed this USB device.
No, it's still terrible.

I always have to hover over the links on Slashdot to see which one is the article discussed.
Here a rule: Links should be a noun (or noun phrase) that tell you where the link will take you.
Taco gets it wrong.

Here's something to try:

The broadcast video processor (also from b&h) is also useful for this application. I like to put it before the TBC.

Sun's spokesman Siress needs to learn the difference between an adjective and an adverb:
"I think you can see OpenOffice running solid on OS X by the end of this calendar year"
"Microsoft is mad, and Apple's coming at them hardcore."

Spoken English, transcribed literally, is nearly indecipherable.
