In Australia, if you as an employee lose a hand or eye or worse due to negligance (eg failure to provide a safe working environment), your employer could be fined and/or go to jail. So even if an employer doesn't care about his/her employees in an emotional sense, they are sure to care about their wellbeing for other reasons.
Unfortunately, like the US (as seen from my armchair:) our negligence laws are getting such that you have to take the stupidity and lack of common sense of other people into account. Hopefully we won't ever have to (or haven't already) gotten to the point of having to warn people that their coffee might be hot.
I think you'll find that ozone depletion and the greenhouse effect are two completely separate things. (only similar in that both are considered to be a bad thing for the environment)
Whether used in a HFC, or just burnt in a combustion engine, any process which combines Hydrogen and Oxygen to produce energy is going to produce water.
Yes, setting the bar at the intelligence level of some humans would be aiming a bit low. Such a computer as a customer will similarly respond to a request for their IP address as:
"I'm sorry Dave, I can't do that."
And then try and kill you when it thinks you are plotting against it.
One of the likely scenarios being explored here is that the laptop would be stolen by another university student. If the laptop and the university are both wireless capable and the laptop is switched on, it could phone home before being logged in with the right software. Failing that, it would have to be plugged in which a thief who was even remotely clever wouldn't do without checking it out first.
My best advice would be to install a drivelock password, which will render the laptop useless to anyone who doesn't know the password. This functionality is part of the ide drive, and cannot be easily defeated. Replacing the drive in some laptops will result in the password being re-applied to the new drive. If you can't have it, nobody can! (of course, make sure _you_ know the password and store it in a safe place)
If god didn't want us to eat animals, why did he make them so tasty?
On a more serious note, it would make a lot of sense to seriously cut down on the amount of meat we eat for more reasons than just the amount of energy it takes to grow it.
I can just imagine the future... planting trees will be environmentally unfriendly. Forrests will be burnt down to increase the CO2 content of the atmosphere. Governments will subsidise fossil fuel burning vehicles and levy electric vehicles.
Environment day will be celebrated with huge bonfires.
And we'll all be sitting in rocking chairs on our porches telling anyone who'll listen "back in my day..."
Here's a challenge to anyone who has the time and patience - put "ALL YOUR BASE ARE BELONG TO US" on a google map somewhere. eg mark it out on some vacant land somewhere and wait (up to 4 years?) for a new image to be taken of your area. s/AYBABTU/something else cool
I nearly found this out first hand in my company vehicle. I was pulled over for a random breath test (we don't have field sobriety tests in Australia, just breath tests afaik). I passed that with flying colors, but then I was asked to park the car around the corner, because it didn't appear to have current registration.
The police officer made a call and found that it was registered, it just didn't have the current sticker on it. I think I could have been fined for this but they just asked that I take care of it as soon as possible and then sent me on my way. It turned out that the current registration sticker was on a desk in the office somewhere, and just hadn't been given to me yet.
Work pays for all the expenses associated with the car (registration, petrol, insurance, servicing, etc), and part from the petrol, pays for them directly (i never see the bills) but I drive the car as a personal vehicle, so i'm not sure exactly where I would have stood from a legal point of view.
for $20 or so per PC you should be able to get some pci cards with a flash chip on them that can restore a PC every time it is rebooted, and do so so quickly that you'd never even notice.
Failing that, you should have a start and forget method of restoring a PC to the way it was. If you are restoring each PC that breaks manually then you are working harder, not smarter.
Maybe to circumvent the students who just want to play rather than deliberately cause trouble, allocate a small handful of computers, separate from your main network but connected enough to the internet, and say go for it. Make sure the PC's get re-imaged nightly, and monitor them somehow so that if anything illegal is done from your network, you can identify those responsible.
The summer before I started Uni (1994), i think the university had gotten into a fair amount of trouble due to the activities of a few students. The feds had come knocking on a few doors looking for those responsible. Consequently the year I started the university was draconian about security. I managed to lose my computer access for a week twice, once for accessing my account externally, and once for having a world readable folder in my home directory. I should have paid closer attention to the TOS.
The question isn't _that_ funny in itself, it's watching a child trying to figure it out that makes me giggle (and maybe it's only me?). It makes sense numerically, (5 - 7 + x = 0, solve for x), but not when described as a 'story' (eg I have 3 apples, and I give 2 to you, how many apples do I have now?)
I'm not sure if the cab system differs in London compared to where I live, but I'd predict a large increase in abandoned calls from locations people have bought a lot of property on.
1. You wouldn't be in direct control of the soldiers, they'd just go where they wanted to. 2. Assuming you could work around the above, then lag might be a problem. 3. I doubt that neither allied or enemy soldiers would consent to having remotely readable GPS units attached to their person.
And a dice roll is deterministic? The only real difference I see with this is that the cab's don't travel around the board, they go from anywhere to anywhere else directly.
Even the concept of jail probably exists if the cabbie does something wrong.
Seriously, even the keys i pressed didn't come up. The server/router in question is a Compaq Proliant 1600 with a single 350Mhz CPU.
If you consider a server sending UDP packets as fast as it possibly can over a gigabit network link to another server (router) which may have to do NAT and filtering, and QoS (only 2mbit outgoing from the router), it can cause enough interrupt activity that the cpu just doesn't have time for anything else.
For some quick (and possibly incorrect calculations), say it is sending 100 byte packets. 100 bytes = 800 bits +50% to account for overhead to put the packet on the wire = 1200 bits 1200 bits @ 10^9 bits / second ~= 833000 packets / second assuming a 1 interrupt per packet ethernet card, and a 350mhz cpu, that gives you 420 cpu cycles to process the packet. processing the packet will consist of: . ethernet validation (checksums and whatever else) . de-encapsulation of the ip payload . ip validation (source, dest address etc) . traversing the routing tables . traversing the firewall tables
and that doesn't include sending it out the other interface again. Also consider that being a linux router, it's also doing a few other minor tasks like traffic accounting.
Remember UDP is different to TCP, with TCP the dropped packets would be detected and the transmission slowed to a rate that the routers outgoing interface could accept them at. UDP has no such flow control.
And as I said, unplugging the network cable brought the router back to life instantly.
I've seen this happen with cisco routers too, so it's not just a limitation of linux, although I imagine the load required to down my low powered linux router would be less than that required to have the same effect on a cisco router.
Other than a few cases of overload that I have experienced caused by either my stupidity, or an infected laptop being plugged into the network, the router has performed admirably.
If you've ever had one of the recent worms come in behind a linux router, then you'll see how network traffic can make a cpu stop.
I made a boo boo in a firewall rule and opened up an unpatched mssql server to the internet (*hangs head in shame*). Within 30 seconds it had caught one of the mssql worms and had stopped the linux router dead. Pulling the network plug from the mssql server caused the linux router to come instantly back to life. With TCP and all its flow control goodness it's probably not a problem, but when something is sending udp or icmp packets at you as fast as it can, you'll really see the difference.
Yes those machines will surely get reinfected within a few days/weeks
What if the bot could be told to configure autoupdate to automatically download and install the updates (as opposed to the configuration option that requires user interaction). And turn on windows firewall if it is disabled (by the user or by the trojan). And maybe also configure IE and Outlook for 'safer' behaviour (no activex controls etc). Maybe it could even download autoupdate if it isn't already installed.
And then finally install Linux, just to make a point.
Hence the 'if'. That is the only case I could think of where there might be a reason to have a law to stop people looking at computer generated images of child pornography.
I was in no way implying that it might be true, I don't know enough in that field to even have an opinion, other than (on a purely emotional level) it just doesn't seem right.
What if it's all computer generated and no real people are involved? In that case the act of creating those images is truly victimless.
I feel that it would still be wrong, but you can't (or at least shouldn't) make a law preventing a person doing something that affects no-one else just because 1 (or a million) person doesn't like it.
If it could be proven that somone who likes to view such images presents a risk to society (in that they might act out the scenes portrayed in the images) then you might have a case. But maybe viewing those sort of images would satisfy whatever deviant urges that person has, and so by generating them you have actually done the world a service. Good luck proving either case in a court of law though.
When I opened up the image in GIMP, I could vaguely see two identical-looking images (only at 16% scaling though, the image being visible must have been an artifact of my laptop screen).
Assuming that the two copies are the first and second frames of one interlaced tv frame, then we are talking about 4096 x 2048 x 8 bits = 8388608 megabytes of data to generate one tv frame.
For motion picture, at 25 interlaced frames per second, thats just under 210 megabytes of data you'd have to move every second. And, moved with enough consideration to timing that you're not wiping out a frame while it's being drawn.
We can take into account that there is overscan, vsync and hsync 'signal' that doesn't need to be refresh each scan, which might eliminate some data requirements for refreshing, it's still going to be a fair bit of data.
Is that feasible? (or am I wrong about 1 VGA frame being 1 PAL image?)
But surely getting revenue from their existing music is what keeps them from getting off their bums and recording new music.
Or at least it would, if Michael Jackson hadn't bought the rights to all of them.
But seriously, I don't really agree with the principal that you should be able to have one great idea / song / whatever and get revenue from it forever. That just promotes laziness & greed. A patent or copyright should be granted for long enough to recover your costs, relax for a while, and come up with a new song / invention. If you haven't come up with one by then, then you should go out and get a real job.
(it should be noted that i have no musical talent, and at 29 and with 4 kids, i'm unlikely to come up with any ideas that are going to make me rich, so there may be an element of envy in the previous paragraph:)
How about 'Identity Duplication', or maybe 'Cloning'?
True identity theft would involve assuming someone's identity and making sure that they would never be identified as themselves anymore. There are other laws governing the steps someone would have to go to to do that though.
