It's used for younger kids. However, if I recall correctly, I had a box (a small empty square) or sometimes a blank space denoted by an underscore. I guess they think it's easier for them to understand something that represents blank rather than 'x'.
It's to introduce algebra concepts to kids before they're in algebra (maybe >5 years before).
Why does the vehicle ABS (from what I know from the news) get tripped up on instant breaking?
You're confusing two different issues. Some (many) models have having an accelerator problem. Supposedly, the car takes off and there's no way to stop it.
Then, there's the brake issue with the Prius. If you press on the brake lightly, it only uses the regenerative braking (electric). If you hit a pothole, the ABS kicks in and there's a switchover to the friction brakes. You temporarily lose some braking force and it feels like the car is floating or (as some have reported) accelerating.
I own the affected Prius model. I've experienced the issue and I don't think it's a problem. It was a little unnerving until I realized what it was. If I really need to stop sooner when the brakes "fail", all I have to do is hit the pedal harder and it does what I expect.
This was going to be my senior project...the exact same thing We thought we were the first ones to come up with it. Sadly, it seems, the Japanese beat us to it...
My understanding is that linux allows you to grow an array. Yes, it will, I just checked the manpage for mdadm. For RAID 5, and probably similar for others, the procedure is to "fail" each of your disks by unplugging them then replacing them with the bigger disks (this part isn't in the man page). You just have to make sure that you allow to RAID to rebuild after each "failure". Once they're all replaced, you can resize the array to fill up the new, larger drives. Then, of course, you'll have to resize your filesystem. During this process, however, your RAID will be vulerable to real disk failures.
The true horror of this drug is that if it does become commonplace and people need less sleep, my bet is that capitalism will adapt itself to this new reality and we will soon be working 14-16 hour days.
Will soon be working 14-16 hour days? You obviously aren't an engineer.
I was pondering something about this not too long ago. Let's say we can program the ENTIRE universe into this thing. Everything down to the smallest level. Oh yeah, we also have to assume that everything is governed by strict rules, none of this quantum mechanics stuff that allows for weird things to happen with probability. The computer would essencially be able to track all of history. Here's the problem:
When the program gets to the point that the computer was turned on, it would have to start taking the entropy it generates into account. In doing so, it alters it. And would have to also take the new alterations into account. It would get stuck in an infinite loop and never be able to progress into the future. Actually, it'd be stuck a little in the past (whenever it was turned on).
I didn't watch the kick-off, but my guess for the reasoning behind all the simplification is to level the playing field (so to speak). As rookies last year, my team had to start completely from scratch. After a few weeks of floundering around, we managed to hash stuff together. After managing to organize ourselves, we had to learn some engineering skills. Even though our robot shipped non-functional and untested, we did pretty well. We even made it into the semi-finals in our regional.
During today's brainstorming, there was some speak of simply modifying last year's design. Veteran teams have this sort of advantage every year. Use the same drive train...use a stronger actuator...scrap one of the appendeges... Veteran teams always have some place to start. But this time around, the rookies have a leg up. They aren't working from nothing.
I suspect that you can get linux to work with one of those old cradle modem things (don't know what they're called - before my time). Then you can dial the number on your cell and drop it in.
Personally, I don't think that they should be allowed to tax any communications. Actually, I take that back. They can tax it if they only use the money to pay for it.
Taxing communications is like taxing air. We all need to communicate with others the same way we all need to breath. Why not just tax people on the streets for talking to each other?
Methinks it be time to go on a rage-filled killing spree to avenge the obselesence of my copper line.
I'm too far from the CO, so my ADSL (384/384...no that's not a typo, SBC is selling me 384/128, but the modem and speed tests say otherwise) is painfully slow (relatively). Actually, for some reason my upload is about 10kbps faster than my download. I don't know why it's that way, but it pisses me off because it doesn't help me very much.
There's some FUD here. I suspect that the general population will have a problem with it. People fear all things nuclear.
Another issue is that there is some uncertainty in the life of this "battery." I'm not a scientist, but my understanding is that a half-life is the amount of time it takes for half of the material to decay. That means that there is a 50/50 chance of a particular particle decaying in one half-life. So, there is only a high probability of this stuff breaking down in a certain time. Is the sample small enough for some of them to completely die before the end of it's expected life?
I also doubt that it will be widely used any time soon. People will be afraid of them. There will probalby also be some legal issues with production and disposal of the devices. Particularly in this post 9/11 America.
I just realized that if everyone starts using hydrogen cars, LA would turn into a tropical jungle instead of having a blanket of smog over it.

Hm...I suspect the hippies would have a problem with that. We could have millions of hamsters running on wheels with generators to separate water...wait, they might not like that either. I suspect that wind or solar might be most effective. Although, using electricity from a hydroelectic plant could be fun.

I tried to compile it, but it's missing TravelerDiskWizard.h. I was really looking forward to playing with this thing...

I think we need to stop making our computers go so fast. We're only making things easier for Skynet.
