[erlang-questions] Learning Erlang from the scratch

greetings,

my main problem with the alioth shootout is that it has thrown away one 
of the main ideas/insights from the paper(*) that was the inspiration 
for the original shootout. namely that it is very important to look at 
how the timeing changes with the size of the input.
the alioth shootout takes only 3 very similar size values.
to make things worse these 3 values must give results for the major 
languages (no timeout, etc).

(*)Timing Trials, or, the Trials of Timing,

Those were the days...
    EPO guidelines 1978: "If the contribution to the known art resides
    solely in a computer program then the subject matter is not
    patentable in whatever manner it may be presented in the claims."
