Hexadecimal Numbering System. Upside-Down-Ternet. My neighbours are stealing my wireless internet access. I could encrypt it or alternately I could have fun. I'm starting here by splitting the network into two parts, the trusted half and the untrusted half. The trusted half has one netblock, the untrusted a different netblock. We use the DHCP server to identify mac addresses to give out the relevant addresses. /etc/dhcpd.conf IPtables is Fun! Suddenly everything is kittens! /sbin/iptables -A PREROUTING -s 192.168.0.0/255.255.255.0 -p tcp -j DNAT --to-destination 64.111.96.38 For the uninitiated, this redirects all traffic to kittenwar.
For more fun, we set iptables to forward everything to a transparent squid proxy running on port 80 on the machine. /sbin/iptables -A PREROUTING -s 192.168.0.0/255.255.255.0 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.0.1 That machine runs squid with a trivial redirector that downloads images, uses mogrify to turn them upside down and serves them out of its local webserver. The redirection script. Row Three & Brave New Worldview - 30 Science Fiction Films of the 21st Century. A decade into the 21st Century and we have arrived at the future. The promise of Tomorrow. But instead we have looming energy crises, endless middle east conflict and more disappointing, we have no flying cars, Heck, for all the bright and clean future promised in 2001: A Space Odyssey, none of the real companies used as brands in the film even exist anymore.
Even moving from the late 1960s to the mid 1980s, nobody makes DeLoreans (although they occasionally sell on Ebay), but cloning and tablet computing (as promised by Star Trek: The Next Generation) have more or less come to pass in this century. It is not the gizmos or the distopian aesthetics, that have brought Science Fiction into the new millennium, but the questions it asks of people or society in a future time or place and how they reflect on our own times. There have been a surprising number of excellent science fiction films to come about in the past decade that do this and do this well.

Databases and Archives Books and Journals Science Math and Technology Social Science. The Winning Edge. In the summer of 1994, in the tallest of Princeton University's ivory towers, Andrew Wiles was completing one of the most extraordinary odysseys in the history of math. For more than three decades, Wiles had been obsessed with Fermat's Last Theorem, a seemingly simple problem that had stumped mathematicians for 350 years.
French mathematician Pierre de Fermat had noted that although there are plenty of solutions to the equation X2 + Y2 = Z2 (for example, 32 + 42 = 52), there is no corresponding solution if the numbers are cubed instead of squared. In fact, Fermat scribbled in the margin of a book that he had "truly marvelous" proof that the equation Xn + Yn = Zn has no solution if n is any number greater than 2.
Unfortunately, he never put his proof on paper. Wiles was 10 years old when he encountered the theorem. "It looked so simple, and yet all the great mathematicians in history couldn't solve it. I knew from that moment that I had to. " A media frenzy followed. Top 6 Sites that Inspire and Educate & Life Scoop.
