So what did people watch before cable came along then? Or did TV not arrive where you live until
the 70s?
They watched VHF channels 2-13. Even if there happens to still be an TV antenna on top of your hours it was primarily designed to be good at receiving VHF signals with UHF thrown in as an afterthought.
I don't see why you'd have a particualr problem if you implemented your system with the industry standard TKIP and 802.1x. After reading the UMD paper it seems that the two types of attacks can both be prevented with those systems. If you use 802.1x authentication without TKIP you could run into problems with the session hijacking. Most wireless manufacturers do not allow their access points to operate in this mode, though the ever popular Cisco is an exception.
The man in the middle attack can be avoided by using mutual authentication which is a part of the EAP-TLS standard usually used to implement 802.1x. The version of the standard being urged by MS and being shipped with Windows XP can be configured to not have this vulnerability. The problem here is that this must be configured on the client and you might not always have control over the clients.
Please note that the x in 802.1x is not a place holder for the the 1b at the end of 802.11b. 802.1x is a port bases security standard that was developed mostly for the use of switches to allow access even when the physical location of a switch port might not be physically secure.
This standard has been extended for wireless use. The problem described in the paper is quite different from the problem of cracking WEP. 802.1x uses a similar method of authentication and encryption that SSL does. It also provides for the possibility of changing WEP keys periodically. Although WEP is quite flawed, that problem can be avoided by changing the key on a per client basis with greater frequency than is required to determine what the key is.
The problems described by the paper could only happen in an exceptionally poorly configured wireless deployment. For these exploits to work you would have to be using 802.1x with WEP encryption disabled. This would be a strange thing to do since one of the main purposes of using 802.1x is to get effective WEP key rotation. For the man in the middle attack, you would need to have an imporperly configured authentication server (usually RADIUS).
I'm in the US and I'd really like to have an option in the user preferences that allows me exclude all of the "this is about something in the US so it sucks" comments. If it could also block all of the "this is boring and slashdot sucks" comments and the "this is old news, why would we want to talk about old news?" comments.
Honestly, if you don't find something interesting don't waste your time and mine by writing a comment about it. There are probably quite a few people out here who do find it interesting and worth discussing.
Any bets on if or when the olympics will again be the pillar of integrity?
I'll put my money on tonight at 5:30 when Tom Brokaw reports that the Olympics are the pillar of integrity, honesty, truth, resourcefulness and the American way.
I understand what you're saying, but I still don't completely agree with you. Corrupted memory isn't the worst thing that can happen. Corruption of data in memory can be repaired with a reboot while corruption of data on disk cannot. I also consider the risk of a program executing a valid but incorrect operation to be vanishingly small. Furthermore, any data which might become corrupted in swap is likely to be relatively unimportant, otherwise it wouldn't have been written to swap. If you're going to make use of a unreliable drive somewhere in your system, swap is probably the safest place to do so.
In my opinion, the stronger argument against using an old, slow, modified drive for your swap is perfromance. In most cases another $25 worth of RAM would allow you to turn off virtural memory entirely and not have to worry about these things anymore.
I recently got a real hum-dinger from my Senator (Chuck Grassley, R-IA). I had written to him express my distaste for the Patriot act. He wrote back and told me that he was throwing away all of his mail due to Anthrax. However, he was proud to toot his horn about getting the Patriot act to make me safe from bad people.
What I learned from the experience is that my suspicions were true. My elected representatives don't listen and do dumb shit just to piss me off.
I too have had some troubles with them. Getting a RMA number from them usually seems to take about a month and is just a lot more hassle than it should be.
On the other hand, I still do business with them because they have good prices, a good selections and tend to ship things promptly. If you purchased things from onsale.com/egghead.com a lot of them probably came from computergeeks. They were the supplier for a lot of the stock on the onsale.com auctions.
What you say is true. Any sufficiently qualified idiot can make mistakes when programming. The only catch is that some languages make it easier than others.
For example, I suppose that it would be possible to cut John Ashcroft into small bits with a pair of fingernail clippers, but it wouldn't be nearly as easy as doing it with a really big kitchen knife or a chainsaw. Likewise, it'll be much easier to make the mistake of casting a float as an int and back to a float using Perl than it would be to do the same thing in C++ or java.
Even with a good mind, using a suitable language will help you avoid certian classes of mistakes. Trouble with making a browser based accounting package is that perl is the right language for some parts and the wrong language for others. Real world design gets that way sometimes.
I got some of these 2 years ago. They came prewired on a 2' high fake tree. I'm thinking that the whole thing cost me less than $20USD. It is kind of nice that they don't burn out, but they have a 60Hz flicker, and if they come loose the whole string goes out same as the regular bulbs. I wouldn't pay extra for them, but they're cool if you happen to find some on sale.
I seem to recall building an quite a few sensors in electronics lab in college that used the parallel port. As I recall, the general scheme was to attach the input to a 741 op-amp circuit to increase/decrease the voltage levels as needed. The output of the 741 is then used as the input to a 8 bit analog to digital converter chip. Data can then be collected easily by polling the parallel port.
The GM device you refer to is really pretty simple. The little "chip" embedded in the key is just a resistor. The ignition switch contains a simple ohmmeter that checks to see if the proper key has been inserted, if not it disables the fuel pump for a few minutes. This link explains a bit about how it works. a bit of Google searching will turn up lots more links that describe the system.
The difference between the public sector and the private sector isn't in the concentration of idiots, it's the reach of their decisions. When a private company makes bad decisions, the worst that can happen is that the company in question goes bankrupt. When government makes bad decisions, we end up with unjust laws that apply to everyone and are difficult to change.
Can you please explain how one would go about frying bread?
It's bread toasted in a frying pan with a light coat of butter. Americans might better know this dish as texas toast, though that term usually implies that you have prepared an unusually large slice of bread in this manner.
Setting the room up in such a way as to include a pool table would probably be a good thing. This would not only be a cool thing to have in your arcade room, but would also help to define the role of the room in the minds of non-geek sorts if/when you need to sell your home. If pool isn't your thing, an air hockey table would server a similar purpose and fit in well with the '80s arcade theme too.
If you do decide to put in a pool table, make sure that you put some thought into lighting. Pool tables need good light, but you don't want to get glare on the glass of your games nor do you want to interfere with the dark and dank look of the room.
In terms of getting the dark and dank look, I'd go for a very dark green flat paint. Dark green is going to be more appealing to the "normals" than black will, but under dim light should look just about the same.
It's extortion. AT&T made an offer to buy the network from excite@home and the bond holders didn't think that it was high enough. They think that AT&T or some other entity who has an interest in having the network operational will make a better offer when they are under a more real threat of having the network turned off.
... or really any higher form of life than a cockroach.
Wait, I thought you said you didn't condone killing the P or VP.:)
While neigther the P nor the VP are extremely tall men, they are each significantly taller than a cockroach. In this sense they are higher froms of life than a cockroach.
When I was in Japan a few years ago I found that carrying a small notepad (you know, one of those paper things with the wire spiral. It's about the size of a Palm III) with me was useful. Having a bit of paper to use for scratching out numbers and diagrams makes it possible to haggle over prices and things like that without the need to do very much talking.

This is entirely conjecture but I suspect the reason is to prevent theft of artifacts from dig sites.

Pages get corrupt, swapped back in... instant swiss cheese computer.
What happens then? Netscape crashes and you lose the witty /. comment you were typing.
On the other hand, you could not do this mod and then what happens? Netscape crashes and you lose the witty /. comment you were typing.
Fact is that most people will tolerate their desktop computer crashing on occasion. That's why some people still use windows 9x.
I don't understand. You speak as though there was some sort of a difference to begin with.
But racketeering and RICO laws probably do.
