Where's he going to get the original uncompressed source for encoding? DVD compression is inefficient enough that you can transcode to a smaller format without much loss.
I'm currently using a netbook as my primary computer, following hardware failure. I plugged in a real keyboard, mouse and speakers, which solves the biggest usability problem, and I'm running Ubuntu using the Maximus window manager to get the best use of the small screen. I've also customized Firefox to avoid wasted space. The biggest hardware limitation is the ram size. It's hard to go back from 4GB to 512MB. Hopefully I'll soon be back on a better computer, but the netbook is tolerable.

It replicates when placed in the environment of HighLife (variant of Conway's Life). Like Conway's Life, this environment allows for universal computation. Self-replicators are also proven to exist under Conway's Life, although none are yet constructed.
If you don't believe that 49bit pattern is alive then you shouldn't believe viruses are alive.
My Microsoft Natural Ergonomic Keyboard 4000 had this problem, and I fixed it by pulling the spacebar forward using adhesive tape. The build quality and key action is still very poor, but at least now the spacebar doesn't jam when I press it in a corner. Despite the problems this is the best keyboard I've used because of the superior layout. I comfortably touch type 80wpm+ using self taught incorrect technique.
Training enough that you can react before conscious thought is the only way to play twitch games competitively. Ordinary hardware carefully selected and tuned for low latency is enough for this.
A large proportion of latency is a multiple of the frame time, so increasing frame rate will have great latency advantages as well as improving the motion quality and reducing the sample and hold blur.
There are currently 3 true 120Hz LCDs.
ViewSonic VX2265wm (defective brightness control) Samsung 2233rz (which has slightly higher latency, and also defective brightness control) ViewSonic VX2268wm (only LCD without serious defects).
Note that these are all TN panel, so they will have unacceptable color unless viewed from directly from the front. They are all out of your budget. There are also a few true 75Hz LCDs, but beware than most "75Hz" LCDs drop frames to 60Hz.
And a lot of people dance to drum and bass at half tempo. I used to dance at full speed, but I find it too tiring now. 500bpm is fast enough that its hard to distinguish individual beats.
TN panels have acceptable image quality if they have gloss finish, no obvious light sources nearby to reflect off them, and are viewed from directly in front. This isn't too difficult to arrange for a non-portable monitor. If you disagree then there are currently zero "good" LCDs on the market, as every other LCD is too slow or has defective brightness control.
The point of limiting the number of player projectiles on screen is to provide a risk/reward mechanic by encouraging you to move closer to the enemies. You'll do more damage, but you'll have less time to react. Rewarding risky behavior is generally good design.
Startup time only makes sense if it's a choice. Having to decide on the responsive but weak attack and the stronger but laggier one potentially adds tactical depth and can make the game more interesting. If every attack has added latency in some misguided attempt at "realism" it's just bad game design.
The only inherent display latency of a CRT is the time taken for the beam to arrive at any particular part of the screen. In the worst case this is one frame, which at a reasonable refresh rate (100Hz+) will be only 10ms or less. A good LCD (there's only one on the market, the ViewSonic VX2268wm) updates in the same line by line fashion as a CRT, and will add only a few more milliseconds switching time latency.
Of course you still have the latency in the input/processing/rendering stages, but this doesn't have to be very high (increase input sampling rate, avoid any interpolation, disable graphics buffering, etc). The only reason most modern console games are unplayable is because reviewers all ignore latency, and low latency can be traded for higher graphics detail which the reviewers pay attention to.
Perceived latency has nothing to do with reaction time.
Response time is more important. For bulk data processing you can leave it running overnight. You're not there to notice any slowdown. If you do this kind of processing often then you'll probably have a dedicated machine with a kernel optimized for the task, but for most people it makes no difference if it took 6 hour or 8 hours.
I use a latency tuned 2.6 kernel, but even on fast Core 2 Duo with 4GB ram I'm not happy with interface responsiveness. I'm very interested in this new scheduler.
"Whatever temporal sampling rate you choose, it's unlikely to be fast enough There is no practical frame rate high enough to properly portray all the motion typically encountered."
In practice you get diminishing returns as you increase the frame rate, but there'd have to be something very wrong with you to not see the difference between 30fps and 60fps.
Just as learning Lisp will improve your programming skills in mainstream programming languages, learning a foreign language will improve your communication skills in your native language.
"Higher education" is really a medieval style guild system, and it has no place in modern society. With ubiquitous internet access anyone with sufficient talent and motivation can teach themself any subject to any level. The only remaining step is to decouple the certification from the training.
It's true that some people will learn better with a teacher and fellow students, but there's no reason this has to be within academia. Students could save a lot of money by cutting out the middle-men and hiring teachers directly.
It's trivially easy to tell the difference between 30fps and 60fps in a side by side comparison even for untrained people. The difference between 60fps and 120fps is more subtle, but well worth getting hardware capable of displaying it without problems (which means either a high end CRT or a ViewSonic VX2268wm).
I remember playing against Dreamcast users, and it was more a one sided massacre than a fair game. The Dreamcast players didn't stand a chance against even lower skilled PC players. The scoreboard was divided into two clear groups with all the Dreamcast players at the bottom. I didn't play for long because it got boring very quickly. IIRC the crossplatform play feature was disabled soon after it was introduced because it was too frustrating for the Dreamcast players.
The events may be outside your control, but your reaction is not. Pessimists prepare for disaster, optimists assume they don't need to. Preparing for disaster isn't free, so the optimists win if it never happens.
Optimism leaves you more affected by events out of your control. Some of those optimists will be lucky and end up successful, and some will not. If you only look at the successful people you might think optimism causes success, but that's because you didn't notice those for whom optimism didn't work out.
Why should we believe anything said by an industry based around tricking people? More likely the anti-astroturfing is itself astroturfing, and their only goal is to distract attention from it not prevent it.
Looking for references, tactile reaction time seems to vary depending on location and nature of the stimulus. It may sometimes be slower than visual reaction time.
IR vision wouldn't be annoying if it were on a separate channel to normal color vision. A few humans are suspected of having tetrachromatic vision, so the brain probably supports more color channels.

That hash is too easily reversible. Brute force search in order of name popularity.

Usually I wouldn't bother correcting mistakes like this, but you're a teacher.
I'm talking about sustained FPS, and you obviously have either never done the comparison or have severe vision problems.
