Yes, FireWire is bad in this regard, because it normally allows devices direct DMA to other devices memory space. This is also what makes/made it so popular for high-bandwidth/low-latency applications. But keep in mind that this i

At that time, rectifiers often consisted of a AC motor driving a DC generator. Which probably could have been moved to customers, but was avoided for maintenance and reliability reasons (more easy to service one big generator/motor pai

A power-supply with 70-80% efficiency (at, say, around 50% of the power-rating) would be a very, very crappy one. On the other hand, a DC/DC with 98% would be a very good one. So your comparison is not really fair. See e.g. the book me

So, often people will image a computer (e.g. to a 2nd harddisk or DVD) after changes had been made. So returning after one year you'll find that the hardware had failed for whatever reason and the image put back on another PC. So, rest

I second the recommendation for Beyerdynamic's DT-770. They are standard equipment in recording studios because of their superb sound, good isolation (they are what's called a closed design) and ruggedness. You can also get a lot

The parent comment didn't refer to the 120V / 240V distinction because of the voltage itself, but rather refers to two distinct kinds of electrical sockets. 120V = NMEA-5, 240V = NMEA-6 http://en.wikipedia.org/wiki
