[erlang-questions] FOP (was: Re: Trace-Driven Development)
Thu Jun 7 13:20:54 CEST 2012
As Ulf's blow-by-blow demonstrates, getting from "I want to add a
period to the end of a sentence that doesn't have one" in the
Erlang/OTP docs to actually adding that period, starting from scratch,
is a tortuous path, with diversions like FOP, the problem of
installing Erlang/OTP, building the docs, etc. And that's not even the
whole story: you're not actually making a change. You're submitting a
patch, and people at Ericsson have to review your "append a period"
operation. You might not see it online until the next release.
I'm now going to time myself on adding a sentence to an embryonic wiki
I started not long ago.
Tick, tick, tick ...
OK, about 35 seconds -- several of which were spent identifying the
URL of the wiki and waiting for it to come up. And here's the change.
I'll time myself on reverting that change:
About 10 seconds. Some of which were spent waiting because
referata.com can be a little slow.
Wikis are, of course, utterly retarded, a completely stupid idea. I
don't know why anybody ever thought they could work for any purpose
whatsoever, because they could only work when an intelligent and
devoted community of users contributes to them, and in the Erlang/OTP
community, there's an incredible shortage of ...
Um, wait, I think maybe there's something wrong with one of my premises.
