No. This is a philosophical problem called "First Cause". This is what will happen. You will say it was little green men. I will say something like, "And where did they come from?", and you will say something like, "Oh, the little green men before them." And I will say, "And where did THEY come from?" and you will say, "The little green men before THEM". And then at some point, we will reach the end.
You're very clever, young man, very clever, but it's little green men all the way down!
Already done on a lot of common distros. Its not installing that's the problem. Its the ease of use after the install. I can install linux on anybody's machine, but that doesn't mean the end user can actually use it once its installed.
That isn't to say that all traffic is bad traffic. Most of the time that traffic you're seeing isn't YOUR traffic. Its the traffic of all the other computers on the network talking with yours. This isn't a bad thing. Its typical of a large network. You'll have lots of computers talking to each other to let each other know when something changes. For instance, a new computer comes online and has to get an ip address. Usually it doesn't know where to get an ip address, so it sends out a broadcast to all computers on the network (yours too). Your computer sees these, but ignores them because you're not the computer giving out ip addresses. Sometimes its more along the lines of "Hello, my name is JoeUsersPC."
If you're alone on your network, (ie behind a router/firewall) then you shouldn't see much traffic other than your computer chatting with the router/firewall. Your router/firewall should block out most of the noise (and that's what most of it is - noise). Contact your cable/dsl company to see if your cable modem or dsl modem has a firewall built in if you're not sure. If, however, you're seeing lots of traffic on typical IRC ports (6997-6999) to typical irc servers (irc.somethinghere.net) and you don't have any programs open, then you're likely a zombie.
By the way, ethereal is located here. Its probably too advanced for the first article submitter, however. I would suggest looking at netstat at the command prompt first.
What's going to happen when I'm trying to do something important? I mean, sometimes I like to play music while I'm doing other stuff like playing games. If I'm ripping/encoding, how much of a performance drain is that glitz and glamour going to be? How much of that crap is going to be loaded into memory when its minimized or not visible? Has anyone done any performance benchmarks instead of just ooh-ing and ahh-ing over the pretty graphics?
Note: I currently run XP on a Duron 900Mhz with a Voodoo3 and 512MB of RAM to surf the internet. Windows XP runs perfectly acceptable on this PC. I guess that means I won't be installing Vista on it:(
Maybe that it tries to propagate on outgoing port 666, and your router would download this information and block port 666. It would also be able to update all the routers in your network.
Wee! Now we can shutdown the internet with a well placed virus. If you can talk with your router, certainly I can as well. All I need to do is pretend I'm the authorative router (DNS poisoning maybe?) or hack the authoritive router and suddenly I get control of your entire network next time your routers update with my virus infected definition file. Let's just block everything except for port 666 so my virus can still propegate and redirect all port 80 traffic to goatse shall we?
If so, I don't think we have to fear trusted computing as this is an example of how it could be a _good_ thing.
Actually, this is the perfect example of how it can be a bad thing. Admittedly, the likelyhood of this happening is probably rare, but I'll bet there are people out there who will try.

I agree with the grandparent. The teacher should just be there to give direction and be another aid in learning. Tests and homework should be there to serve as a test of knowledge so that you know where you're supposed to be and what you still need to learn and a way of learning more (actually by practicing instead of just listening to lecture, etc).
Having said that, however, both teachers and students get it wrong when they're more concerned with the grade letter (and society has helped perpetuate this image) than the actual knowledge the grade letter is supposed to represent.
What (IMO) the grandparent is trying to say is not that the teachers are not supposed to be teaching at all and you're supposed to learn everything on your own, but that teachers are supposed to be an additional resource to help you learn the material. They're there to guide you to where you can find the answers, answer questions you may not be able to find (or don't exist within the context of the textbook) and to show you what you should be learning in that class. Lecture should be just another method of learning what's already in the textbook.

Actually, those are Duplo Lego blocks to be more specific. They're meant for pre-schoolers and are larger than standard Lego bricks. Some standard Lego bricks will fit on Duplo blocks because the top buttons are hollow on the Duplo blocks (the large peg in the middle at the bottom fits inside the top buttons).

Already been done. And quite fun. I know I played it many days during the summer when my dad had the computer tied up.
Some users even insist on knowing why. You tell them you can't send an EXE through the e-mail system, and they ask "why?". You tell them it's a security issue, and they say, "so?"
Telling them its a security issue usually doesn't mean squat to someone. However, if you explain to them that since viruses and other bugs (viruses and bugs are something people understand in meatspace) usually come as EXE files, lots of people think that all EXE files that come over email will infect their computers. Usually other email systems then delete the attachment or bounce the email. Therefore you should zip them (explained as stuffing it in a bag and zipping the bag up) so that their email won't be deleted or bounced back.
Explaining it to them in terms that:
They understand.
Shows them how they're affected (eg: Time, Money, Convenience)
Don't know about more recent versions (I thought they closed shop a long time ago) but their older versions didn't have any spyware. Their software at the time didn't support multiple sources (ala Limewire or Ares) so I stopped using it. Lately I've used http://mp3.baidu.com/ or google filetype:mp3 for faster downloads.
If you click on the balloon, you can see what the message says.
i.e.
Subject: Send money. I had a few beers, then....this. IP Address: 1.2.3.4 DNS Location: too.much.beer.com Location: Middle of the Atlantic Emails: Lots
So evidently there's a lot of people (or one very vocal person) that is being held for ransom in the middle of the ocean after getting wasted one night. Doesn't this happen to everyone at least once in their lives?
1. Something to remove dust from the computers' inside and from the workbench (compressed air...
Whatever you do, do NOT use an air compressor like you would use with power tools and/or to fill a tire. You'll blow components off boards and blades off fans that way. If you do use compressed air, use 1. air in a can or 2. something that has a low pressure (I've seen hand pumps that may fit this bill).
It's also recommended NOT to use compressed air indoors due to the sheer amount of dust you'll put in the air.
Yes, a developer would need to use a compiler, but they could never run the programs made with the compiler because he would need authorization to run them.
Having to talk with IT every time you want to run a different program that isn't on the approved list is idiotic. You're also never likely to get approval for anything because the IT guy who approves things never has the time to sit down and determine whether the requested program is a security risk or not. The request is then denied off hand.
Usually the type of IT person that would implement this strategy is a control freak that won't let people run non-approved software on THEIR network. The only time I see this strategy as being useful is in a university on the lab computers (NOT the professors') or on public terminals because the students aren't supposed to be installing things on the computer anyway. Even then, you want to give them some rights to run programs (again, the developer situation mentioned above)
Besides, if you're not allowed to use non-approved programs, how are you to test the latest open-source alternatives?;)
My wife is an elementary education major who is getting an endorsement in technology, and so is, naturally, very much a believer in education in the classroom.
I think we're all in favor of education in the classroom.
You're forgetting the time it takes for one packet to be received by the other, processed, and sent back. That means you have to include what time you think it is so that the time server can calculate the difference in a reply back so the client can fudge the number based on the calculated time it takes for one packet to be processed and sent from the server to the client.
Of course, this gets seriously fubared when you have really high latency on only one transport (upstream or downstream)
It also doesn't take into account any drifting that might occur (ie a clock that's fast or slow) should the client be unable to contact the server.
Its created when you install the.NET framework 1.1 and used to run ASP.NET programs (so it doesn't run them under administrator). Or, if you read the discription: "Account used for running the ASP.NET worker process (aspnet_wp.exe)"
That does not mean your cash register needs to know the inventory of every item in the store. It just needs to tell a main server that a customer just bought 5 of item 10100101001 at register 16. The server can then say "That can of cat food costs $0.44" and subtract 5 cans from the inventory database after the sale is confirmed. All the cash register should be concerned about is displaying the item and dispensing the right change.
Why would you want to have your inventory on the cash register? That seems to me like an easy way to have redundant data that could be outdated (wrong price, or wrong item) if someone forgets to update the database on the PC (or if automated, something goes wrong in the update process). Plus, you'd have to poll every PC at the end of the day to find out what your inventory was provided you don't talk with the main server after every transaction
If you did have the inventory of every item in the store you would definitely need a PC, however.
Not to mention the security risks (which can be mitigated somewhat) of running a web server with point of sale info.
The idea of some poorly managed retail store stupid enough to let people on their network (unintentionally or intentionally e.g. Starbucks) in combination with a web server running on the internal network just screams "Hack Me".
It's my opinion that you shouldn't need a computer (running Windows!) just to ring people up. That's way too much computer for something that simple. Same goes with ATM machines running Windows 2000.

Or, in Linux, Edit -> Preferences -> Downloads -> Plugins
Though there don't seem to be any plugins there by default.
