Isn't something like y=x^2 a one-way function? Given the input x you can always arrive at the same y, but given y you cannot always arrive at the same x.

until they get a search warrant for your computer and you get sued for every mp3 you can't prove you purchased...

"Technology" was probably too generic of a word, but don't sound so offended. What percent of 70-year-olds you know would have the first clue about bypassing an Internet filter? This post isn't about the few people at the leading edge of a field, or people changing oil in their cars, it's talking about the average person off of the street bypassing an Internet filter.

The OS can't load balance if you don't break your code up into enough threads. For example, If you have 6 threads that each take ~10 seconds, sure the OS should handle it. If you instead only break that code up into 2 threads, one taking 50 seconds and one taking 10 seconds, there's not much the OS can do.

Thought the demonstration of BT was interesting (at ~5:00): "...and you're downloading the movie right now?" "that's right" "the bits moving away...are pieces we have and are sharing with someone else." So CBS was participating in the very activity their program was out to show is illegal...interesting.

Why was this voted down? Do people not ever just coast? What if you're approaching a stop light that's red, for example? If you're not too close to it, it makes sense to let off of the accelerator early in the hopes that it turns green before you have to use the brakes.

Well, if their internet connection no longer exists...

Sounds to me like the parent is speaking of multiple partitions on the same disk. While this is theoretically fine, when I'm doing things like upgrading my OS and wiping a partition, having all of my data so close makes me nervous. I have them on separate partitions on separate disks and it makes me feel better.

UDP would actually better here, since UDP packets are send-and-forget, though you're not guaranteed delivery. Over a high-latency network, you don't want to bother re-transmitting anything for voice communications, because like the above poster said you'd have seconds of silence waiting for the retransmissions.

These can be forced upon you by your employer.

Private business always has an incentive to do things more efficiently! The government has no competition, but the companies compete with each other in order to achieve the highest profits. Whether or not they pass those savings on to the consumer in the form of lower prices is another story...
