No doubt many things will work for 100 Base T, but maybe you won't get the full data rate with the retransmissions that are likely to occur; and the number of errors and re-transmissions depends a lot on the environment and external interferance.
If there are a lot of retransmissions you may find on a busy network that you get ethernet melt-down (due to data collisions cos of the amount of traffic) a lot sooner than you would have done with decent cable and connectors.
Does spidf re-transmit on error? or do you have to hope the error wasn't so great it can't be corrected?
Are you going to wait till your neighbour starts arc-welding before you replace the coat hanger with a decent spidf cable?
Cables quality does matter, _even_if_ low quality cables work somewhat.
Having said that, I don't buy monster cables either, I merely imagine what I may be losing.
You are quite wrong of course, but pretty correct in your point; as long as the signal doesn't degrade to the point of uncertainty where the signal level is close to the data threshold such that noise will cause bits to be at the wrong side of the threshold; as long as the signal doesn't degrade THAT FAR, the signal will be fine. But once the signal does degrade that far you might find a better quality cable will reduce the degradation enough for it not to be an issue.
Does this happen in real life with digital signals?
Sure it does, why do people make sure they get good quality IDE cables (esp. for UDMA), why do we need good quality network cables and connections?
It is true that the lower the data rate the signal will be less susceptable to cheaper cables; but don't be deceived into thinking it doesn't matter; especially in cases where impedance matching is important, or good sheilding is important (to protect the equipment as well as the signal; many a badly designed device has locked up in a damaging mode because of bad signals - this is what the FCC regulations regarding "must be able to accept... interference' refers to I believe).
I think you may find he recovered the symetric RC4 key for bootblock signing and not the assymetric private part used for signing applications, which is the one people really want.
The RC4 key could be used for running new boot ROM's which in turn could run unsigned applications but it requires changes to each xBox to benefit from this.
I've seen them do this, it is a pitiful sight. Some of them can't even walk and chew gum at the same time.
PDF is postscript plus the bits it needs to make it work everywhere.
However tomeraider is not so good IMHO, Mobi Pocket Reader is much better and comes with a free ebook builder for windows, but sadly doesn't supports linux either and wine chokes on installshield install. It seems to be, roughly, a compressed html browser.

Doesn't lack of respect for due process scare you? Or won't you still know what such a thing is when you need it for you?
Are you making your country or just living in the one made by people who have more motiviation for making it than you do. Guess who your country will end up belonging to? hHose who make it what it will become.
Seeing how the US treats mere suspects of terrorism in Cuba, seeing what little respect the US has for due process, I don't think they should be given more help in suspecting people.
They're so busy looking for some reason to suspect it won't take much for person X to paint person Y bad enough to have them carted off.

Capitalism is the new communism, all subcontracted out for profit. Free America is the new oppressive prison state, it's big and you are not encouraged to see the walls.
When I worked at bigwig.net we used procmail and CyberSoft's VFIND and recursive archive-scanner.
If any virus's were detected the original was wrapped as a MIME attachment to a warning message which contained the report by VFIND.
Thus, users could decide what to do about it.
Of course, when we were spammed this made server load go through the roof, it is probably better either to
1) Move the scanning nearer to sendmail so sendmail throttles a bit earlier to save load eating all your CPU 2) Rename.scr,.pif,.js etc attachments and warn the user so intelligent users can rename them back.
Have a bogus PC or bogus windows installation for him to install junk on, which you can leave "unused" till you need to call support when you can boot into that partition if needed.
"Microsoft fall down because the speed at which they fix problems is too slow, not because they try to keep them from script kiddies in the intervening time."
True, and I don't mind them keeping it secret either, I just don't want people saying I can't tell publish my findings to my friends and vice versa. I'm not in favour of a mandatory publish, and I'm against mandatory silence.
I may choose not to patronise the silencers for no better reason than the silence, but what counts most of all is a quick fix installed already.
White Hats and Null Hats also know about vulnerabilities 1) Before they are fixed 2) Before the vendors inform owners of their software of the vulnerability - thankfully.
The gospel of full disclosure is "good news" to these (me) too.
So they (I) can take steps to reduce their own vulnarability. Recent OpenSSH holes could be closed without the fix merely by disabling certain kinds of rarely used authorisation.
Decent sysadmins can often work out decent safety procedures till the official fix.
I don't want to HAVE TO rely someone elses set of approved "white hats" to come up with a short term fix to suit my needs pending an "official" (whose?) fix, I want to be able to do it myself.
Thank heavens for open source, too.
I don't think releasing this information is inexcusable, I think holding it back is inexcusable.
I don't feel the need to argue my point to the satisfaction of anyone in particular, but I will exchange information with those who agree with me, you may feel free to not exchange your information with those who agree with you, for the duration of the embargo period.
I maintain this view after having had a remote with no direct access hacked 3 times and having recovered each time.
Because of my views I don't feel the need to have to judge between vulnerabilities and exploits and how much information on one might leak of another.
I'm not going to bother to convert "just one" drive, I'll want to buy a few, but no way am I spending $400 on that.
$50 is more like it and more within the impulse purchase range for interest users.
I'd pay $100 if each device supported multiple and could control more than one IDE devices (and no it doesn't have to be IDE master/slave, but I wouldn't object)
I'll wait till the price comes down I think, if IDE hasn't moved over to out-of-order command completion by then. If it has then I won't need to bother at all.
...beowulf cluster, do the ITAR regulations cover whether or not it would be possible to make a beowulf cluster of this product?
It's one thing to say the product doesn't destroy the world, but his company is probably hoping for more than one export, maybe enough exports to make a beowulf cluster!!
It won't be a pretty site to see the world destroyed by a beowulf cluster.
Has anybody made a beowulf cluster of beowulf clusters yet?
I saw a circuit diagram to do this based on single sideband modulating the audio signal at 20KHz and mixing with a sine wave 20KHz generated with tweeters.
The book called the circuit a "selective shouter", I saw this in a red hardback book in the library of the Queen Elizabeth I Sixth Form College, Leicester in 1989. I since went back to track down the book but can't find any trace of it.
Try xapian, www.xapian.org, about to undergo it's first release.
It is based on an temporary open-source release of one of SmartLogik's products.
I swear by it and find it highly flexible.
I guess, though, unless you are a hacker - say capable of using to actually index your documents, you might want to wait for the next release.
I use it in preference to htdig, swish++ and others I have looked at and sadly left; xapian is very fast and easily passes the 2G limit systems such as swish++ suffer from, and supports dynamic aggregation of multiple indexes into one search!

The.com bubble makes me laugh; I know what the net is to me, and it's not what the media talk about - which is mostly irrelevant stuff.

Are you looking for a "legitimate occupation" for all your relatives so they admit by most standards that a good vacation was provided, or do you actually want to enjoy time-with-the-family (scarier; esp. if thats not what your guests are expecting).
If the latter, then it's not really what you do as long as you do something; you just need something to a) fill the gaps between conversation b) stimulate more conversation if neccessary
You could look at your local tourist office for things to do that "don't cost money" because they actually have to be fun; things that cost money are usually busy enough or expensive enough to justify themselves.
But I think the.net is just a distraction in this; better to get the old phone out and talk to the family who are coming and take ideas from them; plan it together; it won't actually matter what you plan - you may even end up working on your house; but it's the talking and getting to know that count.
Hackers are not only unpaid support guys for friends and relations, they are also salesmen.
Let the hackers do what they want (and they can't really be stopped, can they), and more will buy the tivo and preach tivo-ism to the untechnical masses who will never hack to the full degree, most will give up after a month and just use it normally.

To right it's about copying features then creating new stuff.
Why?
Because access to the source (so we can tweak somewhat) is all thats missing with most proprietary software.
We don't have new needs, except the need for source, the freedom Richard Stallman talks about.
Thats why.

When you have questions like these never underestimate searching freshmeat.net
It costs time and money to handle complaints.
If your company is taking you for a ride with price, and there are no alternatives:
Talk slowly and eloquently, explain the situation, mention what you are and are not happy with etc.
You should be able to draw the complaint out to about half an hour, and if nothing happens, try again 2 or 3 weeks later.
So I quickly re-registered it with joker.com to make sure I kept it.
