By your magical fractions at 2 miles per hour I am covering 1/2 mile per second. YOU need to double check. Traveling one mile at 70mph does not take 70 seconds. .
Yea but if I could click a button and rob 250,000+ homeless people in the span of an hour or two...
People forget most of this crap that infects PC's are automatic attacks. Some guy in a darkly lit basement doesnt connect to every IP manually to try to hack you, he writes scripts that blast out to tens of thousands of hosts.
You touched on this idea...but a lot of people seem to forget it.
Limited access....pay to use....hmmmm sounds familiar. Oh yea, have you heard of a TOLLWAY! If you dont want to pay the toll, use the other "free" roads to get to work.
Economics. They make a certain number of processor cores per silicon wafer now and throw out some due to manufacturing defects. If you are making the cores bigger you are making less chips per wafer but probably still throwing the same number out, thus you have to raise the price per chip. Will the market bear such an increase?
In addition, propogation delay is significant at nanosecond speeds. In fact, the reason that AMD has put the memory controllers on the die is that a signal CANT move from the CPU down to the northbridge fast enough. Larger dies would mean that you have to be careful what you put at the opposite end of the chip because you wont be getting at it all that fast.
On a side note, I think the signals can go about 3 inches in a single clock cycle at current Ghz speeds.
I was applying the same level of high school understanding as the parent. It's a joke. I have enough EE background already to understand why 600,000 volts isn't deadly.
Your Mark Twain quote is better suited to the parent who started off by admitting he knew almost nothing of electicity then ranted as if V=IR was the only thing at work.
No...no... keep going. You're obviously on the right track as these 600,000 volt stun guns http://www.actionstunguns.com/ deliver an amazingly deadly 600 AMPS through a person. Even deadlier are the ones that pierce the skin and lower your resistance from 1000 ohms to 100! Wow. Good thing we sear our criminals to a baking crisp on the street with over 6,000 amps.
Kudos to you. I have not seen a slashdotter voraciously defend their post this well before. I count 4 distinct ass-kickings handed out by you in this thread.

To all who have replied calling the parent a troll.... There is a situation that can happen where X will hang your keyboard because of some sort of interaction in the kernel and how X handles the keyboard. Anyways, what you get is called a "dead keyboard" which leaves you unable to even switch terminals to fix the problem. Now if by default you are booting into xdm/kdm/whatever it can be a real pain. However, booting without X you can go in and fix it....so the parent IS a troll, however its not too far off from the truth. Perhaps he didn't know how to change runlevels?
Oh man turbo buttons were a riot although ironically it was on all the time and only used to SLOW applications.
A turbo button on my dual athlon-mp 2600s would be a hoot.
That makes free 2 day shipping on all items. Some places charge upwards of $10 for 2nd day shipping and upwards of $30 for overnight. So thats at least a $10 discount everytime you order 2nd day and a $26 discount everytime you order overnight.
You can either pay nothing or 4 dollars... Run it by me again how you think they are screwing you....
This wouldnt be that hard to someone with basic knowledge of sound reproduction on computers and some decent coding skills.
Just because you or I couldnt do it off the tops of our heads doesnt mean this guy doesnt have the prior experience to pull something like this off.
Again, for someone with some prior knowledge its not that hard once you get the concept. Its the concept that blows my mind. Who thinks of playing flash rom out a speaker?!
From the **AA: 666. We are good and keep the artists intrests in mind. We lost so much profit from pirating! Everytime someone downloads a song we lose $125,000! We don't price fix movies or DVDs.
Great screenshots! I use linux and was just going to rely on word-of-mouth, but its really neat that you showed just how dumb this scanner is.
Poor people are going to rely on it it and end up deleting printer drivers and default windows music, PLUS home videos and then proceed to yell at little johnny for doing illegal stuff.
To all you programmers out there, I imagine they would have to lock the memory access while they write it out to disk. But how is this practical?
Do you really want your state information being saved every 5 minutes on a heavily loaded database server with 16GB or ram. Locking the memory pages would be a horrible mess to prevent corruption while pages 1-100 are simultaneously trying to be written to disk and being modified by program A.
Not only that, but as you approach large memory sizes, this becomes infeasable with current technology. The OS would spend most of its time trying to sync 1GB of memory so you get a clean state without mashing a read of variable A with a write on variable A. This becomes an even bigger problem as you get more CPUs in a system. If you want to prevent programs from writng to memory while you copy it down you are going to take a large performance hit, if you let programs modify the memory easier, then you risk not having a sane saved state.
Perhaps they have solved these problems? If they dont have a good idea of what they need to do already this seems like it would be an absolute B**CH to code with an ugly compromise between system speed and concurrent access and getting a reliable saved state.
When I tell VMWware to save my state, it stops THE ENTIRE VM and not a single instruction executed(inside the VM) until its done. Same with console emulators, there is a small pause while they stop the process from running until they're done writing the state.
Then, based on what I said above, how could they possibly be a real-time OS on top of that if they need to HALT execution of certain things to get state info. Real-time performance and saved states seems mutually exclusive to me. If you have even 1 real-time thread you cant afford to stop it to save its state thus your whole RTOS concept dies. If you want real-time you cant guarantee that you'll get a clean state saved.
How are they adressing these VERY LARGE issues? Perhaps someone can enlighten me if I am going in the wrong direction with this though...
(Sorry, I just got done making a C++ class thread safe and its a pain with many compromises. Thats where most of this rant came from.)

Soooo you don't run anything that can DETECT problems so you assume you have none?
Why don't you just put a blindfold on and walk around a cliff. Since you can't see the cliff you obviously aren't in danger of falling.
Do you also forgo backups because you've never had to do a restore?
Do you not have life insurance because you've never died?
I haven't had a virus in years either but you can be damn sure I ALWAYS have my antivirus running.

Holy crap their revenue is going to grow by $10-$99?! :)
Morse code has one big button as its input device you idiot.

Tiger Direct has warehouses with showrooms in Naperville, Illinois and Florida at least.
Has it really come to this? Where people assume brick and mortar stores don't exist anymore?

Almost, you START as a wav then bring *it* down to whatever you want.

Firefox development versions have fixed this already. Probably will be in v 1.1
