It's the "without visible damage" part that is disturbing. If the situation warrants permanently disabling people then they should be using guns.

"OSHA also states that "exposure to impulsive or impact noise should not exceed 140 dB peak sound pressure level" (CFR 1910.95(b)(2))"

This thing runs at 151db, and it's a tight beam so there'll be little volume loss with distance. No matter how brief the blast it will cause hearing damage. This is a device designed for permanently disabling people without visible damage, and it should be banned under international law just as blinding weapons are. Everyone who makes/sells/uses this device should be executed for war crimes.

When you go to college, you're in an educational environment 24/7, getting exposed to more ideas and experiences than most people get otherwise in a lifetime.

In my experience, the Internet provides a much better educational environment. Formal higher education has its own very limited set of ideas and experiences. With very few exceptions (eg. study of chemistry) it can only compete against the Internet because of artificial monopolies.

It's more the "with random writes" part that is impressive (but what size writes?).

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.

Here is a living entity:

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.

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

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.
