one shouldn't forget that computer networking was once not a favorable thing to do.

xerox memo of the month, march 5 1974. to bob metcalf and dave boggs:

I have read with dismay your presentation "Draft Ethernet Overview". As i am sure you are aware, technically or conceptually there is nothing new in your proposal ... The fallacy in your conception is that the stations should be transmitting randomly ... You should seriously study how the telephone companies handle this problem ...

... is rather interesting as well.

"Our practice at the time [...] was to have open and frank critique and internal review of technical papers before they were publicly released. It was in that spirit that I wrote my memo which only took on mythical proportions because CSL Lab Manager Bob Taylor chose to post it on his door."
