The Lincoln-Douglas debates of 1858 were a series of seven debates between Abraham Lincoln, a Republican, and Stephen A. Douglas, a Democrat, for an Illinois in the United States Senate. At that time, U.S. Senators were elected by state legislatures, Lincoln and Douglas were campaigning for their respective parties to win control of the legislature. The debates presaged the issues that Lincoln faced in the 1860 Presidential campaign and are remembered partially for the eloquence of both sides. The main issue in all seven debates was slavery.
the Tanenbaum-Torvalds debate occured in 1992, there purpose was to argue that microkernels are superior to monolithic kernels, i think that this debate was interly most strong toned, and had a very structured debate, because they were both begining to build there rage towards them and thats what makes a debate very structured.
the Norway debate was on may 8 1940 the issue was on a technical motion, and i believe the debate had to be more of a political case then radther a simple debate, i really think this issue was somewhat pointless but it was a very poplular debate.
