Seems to me like it would be a better idea to wear gloves that have someone else's fingerprints engraved on them. And of course destroy those gloves after committing a crime.

I mentioned tracking dots today and someone said "
"well, that's what Kinko's is for!"

Are we talking about criminals or just your average joe six pack turned criminal? Criminals are just going to steal the printer so there is no record of anyone ever purchasing it and then destroy the printer when they're done.
And if you're a REAL criminal, you're not using crappy office equipment to print cash.

A good rule of thumb would be to avoid the use of color copiers that have bill acceptors in their document feeders. (Can you say "entrapment?" I knew you could!)

Actually, if I understand it correctly, the act of reproducing US currancy, by itself, is not against the law - which allows for reproductions in ads and art, but the attempt to use counterfeit money as real currancy is against the law. That's why even if you make crappy looking money and fool a soda machine, it's still against the law, but showing perfect reproductions of money in a magazine ad is not.

I just got back from Phoenix AZ.  While there I visited the Fry's Electronics store.  Damn.  I am impressed.  Hard drives by the pallet.  Boxes of motherboards stacked up.  Every accessory you can think of.

 

I think they sell some other junk too, but who cares about that?

heh, they used to only sell that other junk.
I ermember the first time I went to a fry's, it was like the electronics stores my dad used to take me to when I was a kid that are all but gone now.
I guess they've gone mainstream as well.

Yea, I wish there were still stores selling the "other junk". Canal St (in NYC) used to be lined with such stores. Tons of new, surplus and used electronics.
It was great. Now they are only two surplus places left there, neither of them that exciting. Most of the plastics places are gone too.

I wish there were a Fry's in the northeast. It would be nice to be able to wander in and pick up stuff.

Sadly, these days if you're building something from parts you'll usually have to settle for mail order. Which reminds me ... dunno if y'all already knew about this, but http://octopart.com is a good starting point for that, they've got a search engine for electronic parts so you don't have to go to Mouser, Digikey, etc. etc. looking for what you want.

I wonder if the relationship between economics and globalization will eventually swing the pendulum away from the culture of throw-away electronics.

Speaking of.... I'm looking to purchase a variety of springs. I'd like a large grab bag, with varying sizes.....

Why would it? If anything it'll become moreso.
As things become cheaper to produce (as they will since there will be more buying people to produce for) they'll be less likely to be anything but all the functionality on one chip.
When they get really cheap, they'll just make alinux chip and write everything in software.

That misses the point. "Cheap" is currently cheap because of economic disparity.
Your cheap parts are made by slave labor in China. If we didn't live in an affluent part of the world (some say we're headed in that direction), would those parts then be cheap enough to throw away?

Can someone tell me what a DHCP lease is, and how it affects me? (Or the price of beans in China?)

Sure, write out a check for $300.00 and mail it to me.

 

Seriously though, when your computer logs on a network it contacts a DHCP server.  That server assigns your computer an address so any traffice on the network can find your computer.  Periodically, that address may be reassigned.  Hence, they call it a lease.  As an end user it should be vitually transparent.  If you are a sys-admin or a geek that messes around with your system it might matter.

Right. After that "lease" expires, the address technically isn't yours anymore, which is why a properly functioning DHCP client will eventually "renew" it (usually when the lease period is half over).

Although, a good DHCP server will let you get away with not renewing your lease, because before it hands that address out to someone else it'll ping it first to make sure there isn't anyone using it.

The lease period is set by the server administrator. On a very dynamic network with lots of clients coming and going all the time, the lease period might be very short -- perhaps half an hour at a place like a coffee shop. On a home or office network where it's the same computers all the time, 24 hours or more is common.

And, just to be thorough, if your computer is not set up to accept a DHCP license, it could be set up to statically allocate its IP address, meaning the IP address is always going to be the same, because you chose it yourself, and assigned it to the network interface.

Some DHCP servers will allow you to associate an IP address to a requesting MAC address (read: network interface... all network interfaces have a MAC address), creating the opportunity for a static DHCP address.  This allows you to ensure a particular computer's IP address is always going to be the same when the system boots up, yet the system requests its IP address (and other information, like DNS servers, gateway, and network mask) from DHCP.  This is very useful for situations where you might remove your computer from your own environment and take it somewhere else occasionally, but you still want a stable IP address at your own home.  Or if you just want to keep all your IP addresses in one place; managing IP addresses across several computers can drive you nuts if you have to visit each computer to track what is going on.

And now for a discussion about dynamic addresses on IPv6!

Here's another situation.  A computer with two or more NICs....I was told each NIC needs it's own ip address.  True?



[#] Sun Feb 15 2009 11:05:04 EST from fleeb @ Uncensored

[Reply] [ReplyQuoted] [Headers] [Print]

Yes, I believe that's true.

Otherwise, the network would not know to which MAC address to direct a packet.

Besides, it would do the system no good to have both NICs assigned to the same IP, even if it were possible.

If the two NICs are on isolated network segments (NIC A is nowhere connected to NIC B) I suspect you might be able to use the same IP address, but then your computer might be confused as to where to send a network packet for distribution.  It would need to be designed to act as a bridge, I think, under such a situation.  Perhaps someone who knows more about this could comment.

But couldn't two different MAC addresses share the same IP address?  That shouldn't cause problems as long as it is the same machine using both.  That would allow one machine to use more bandwidth, say on a gigabit network.  I have my house wired for gigabit speeds, but only 2 computers on the network most of the time.  It would be convient if I could increase the bandwidth to a particular computer for special needs.

 

Of course I don't really NEED to do this, I'm just screwing around.
