Moral Action
No Legal Person
People inevitably act. We imagine different possibilities among which we are forced to choose, and we justify our choice if we want to behave as rational beings.

The transfer of carbon dioxide to and from the atmosphere is an essential

Networking Protocols: ARQ, TCP, HTTP, WiFi, and Link Layer Analysis
An ARQ protocol operates between a sender and receiver on a 10Mbps channel (in both directions). Data packets are 10,000 bits each (including headers), and acknowledgment packets are 100 bits each (including headers). The wire is 20Km long. Assume the signal propagation speed on the channel is 2×10^8 m/sec. Assume there is no packet loss and processing delays are negligible.
