Hurricane Dean Pictures...
Texas-Sized Powerful Hurricane Dean Hits Mexico's Yucatan Peninsula
Dean came ashore as a Category 5 hurricane, packing maximum sustained winds of 165 mph.
This image of Hurricane Dean was created with data from Geostationary Operational Environmental Satellite (GOES-12), which is operated by the National Oceanic and Atmospheric Administration. The image was created on August 21 at 9:10 a.m. EDT (13:10 UTC) by NASA's GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md.
S118-E-07918 (18 Aug. 2007) --- A still photo close-up of the eye of Category 4 Hurricane Dean. Crewmembers on the Space Shuttle Endeavour captured this image around Noon CDT of Hurricane Dean in the Caribbean. At the time the shuttle and International Space Station passed overhead, the Category 4 storm was moving westerly at 17 mph nearing Jamaica carrying sustained winds of 150 mph.
S118-E-07920 (18 Aug. 2007) --- Crewmembers on the Space Shuttle Endeavour captured this image around Noon CDT of Hurricane Dean in the Caribbean. At the time the shuttle and International Space Station passed overhead, the Category 4 storm was moving westerly at 17 mph nearing Jamaica carrying sustained winds of 150 mph.

Bit Torrent and Comcast
According to the latest reports, Comcast is hindering Bit Torrent traffic and doing packet shaping. Their method of "throttling" torrent traffic is sending RST packets.
These are the ports that will be affected: (Brian's BitTorrent FAQ and Guide)
Prior to version 3.2, BitTorrent by default uses ports in the range of 6881-6889. As of 3.2 and later, the range has been extended to 6881-6999. (These are all TCP ports, BitTorrent does not use UDP.)
Intrusion detection
"A standard transmission control protocol (TCP) connection is established by sending a SYN packet to the destination computer. If the destination is waiting for a connection on the specified port, it responds with a SYN/ACK packet. The initial sender replies with an ACK packet, and the connection is established. If the destination computer is not waiting for a connection on the specified port, it responds with an RST packet.
Most system logs do not log completed connections until the final ACK packet is received from the source. Sending an RST(Reset) packet instead of the final ACK results in the connection never actually being established."
INFO: Winsock TCP Connection Performance to Unused Ports
"Upon receiving the ACK/RST client from the target host, the client determines that there is indeed no service listening there. In the Microsoft Winsock implementation of TCP, a pending connection will keep attempting to issue SYN packets until a maximum retry value is reached (set in the registry, this value defaults to 3 extra times).
Since an ACK/RST was received from the target host, the TCP layer knows that the target host is indeed reachable and will not double the time-out value in the packet's IP header, as is standard during connection attempts with unacknowledged SYNs. Instead, the pending connection will wait for the base connection's time-out value and reissue another SYN packet to initiate a connection. As long as an ACK/RST packet from an unused port is received, the time-out value will not increase and the process will repeat until the maximum retry value is reached."
So perhaps a way around this is to not use the normal ports that are associated with regular Bit Torrent Protocols as I am sure that they are being monitored. If this is done to all ports then people will start to complain about their service being disrupted on a wide range scale.
