Did you know there is infinity, and then there’s a bigger infinity?
This concept is quite bizarre – one would think that infinity has only one size – that is, infinite size. But this is not true. Georg Cantor, a German mathematician, proved this idea by way of contradiction. Take two infinite sizes – the natural numbers, and real numbers. Both systems are unbounded and infinite in size. It can be proved that one infinity is larger than the other. The opposite is assumed: suppose both sets of numbers have the same size of infinity. By constructing a mapping, we can take an arbitrary mapping and show correspondence. Suppose every natural number has a real partner. We pair them off. In the diagonal construction, it is shown that there exists numbers that can’t be mapped because as your mapping get arbitrarily precise, the real numbers increase still. So there will always be number left unmapped. QED.
Well, it’s been a long time since I’ve updated my website. I was going through my old photos, and I found an album from the 2600 conference, HOPE number 9. I was looking forward to this trip for the past 6 months, I had gathered up some interested friends and all together there were 5 of us.
Morning, just got into NYC.
Backtrack is clearly the standard tool here still.
One giant lock. It’s Medeco.
Homebrew macro mouse. Basically has hardware built in to send keystroke macros to a mouse.
Creator of the wifi gun.
Wifi hacking “gun”. Point and shoot at access point! Self made, with backtrack installed.
Free, good connectivity is important for any conference these days. The question is: do you want to be on the same network as 500+ hackers?
Me on a segway.
3D printer printed.
Lock picking lesson. This particular lock is magnetic. Damn near impossible to pick – magnets orientate the lock into place.
This man looks intense. He showed us how to break out of handcuffs. Not sure if he was really an inmate though.
Author of the book talking about phreaking and the stories from the old, golden days of phreaking. Has a forward by Wozniak.
Phreaking is a slang term coined to describe the activity of a culture of people who study, experiment with, or explore telecommunication systems, such as equipment and systems connected to public telephone networks. As telephone networks have become computerized, phreaking has become closely linked with computer hacking.
The Hotel Pennsylvania is a hotel located at 401 7th Avenue (15 Penn Plaza) in Manhattan, across the street from Pennsylvania Station and Madison Square Garden in New York, NY.
A blue box is an unauthorized electronic device that generates the same tones employed by a telephone operator’s dialing console to switch long-distance calls.  A blue box is a tool that emerged in the 1960s and 70s; it allowed users to route their own calls by emulating the in-band signaling mechanism that then controlled switching in long distance dialing systems.
The old school phreakers did a live demonstration of social engineering on some random poor pizza store.
