How can I tell if someone is using my wireless net?

You have my sincere sympathy.

It's trivially easy to find out, and vetting is a very important part of security.

No credentials in this area at all.

Actually just the opposite, by spreading dangerously bad advice; e.g., (part of my "File and Printer Sharing (NetBIOS) Fact and Fiction").

Start by checking out Bruce Schneier, books, papers, recognition, etc. That should lead you both to his personal website, and to Counterpane Systems. Find out who created Blowfish, Twofish, Solitaire, Helix, and Phelix, not to mention Password Safe. Check out Counterpane Systems.

Then ask yourself how Steve Gibson, self-proclaimed expert on everything, measures up.

Quite, some believe that Rivest, Shamir and Adleman created the RSA encryption algorithm when it was an English guy called Clifford C**ks who thought it up one evening, 4 years years prior to when RSA reinvented and published it.

I have professional problems with Gibson. There's nothing personal about it.

That's more than good enough.

Think what you want. I'm done with this.

And patented it. Since the patent (4,405,829) was never successfully challenged, their claim would seem to have considerable weight. :) But wait! Derek says I can't believe anything on the Internet, and the patent is on the Internet, so I can't believe that either! What to do? What to do?

That's right, they are now credited with the first successful commercial use but not the first discovery. That information only came to light fairly recently as it was covered by the Official Secrets Act in the UK which prohibited its release and any patent challenge I guess.

Citation?

Sure, just Google for "Clifford C**ks official secrets act"

That's not a citation. Try again.

Did you try? Because you'll get loads of links, they just pop right up. Which of loads of pages would you like, they all say the same thing.

David.

Specifically, which of the 918,000 results would you like me to cite? :)
