in reply to poll ideas quest 2009

Does Gödel's incompleteness theorem refute Leibniz's dream about the machine that solves all mathematical problems, as Smullyan suggests?

The argument is that the machine couldn't correctly answer the question "will you answer false to this question"?

  • Yes
  • Yes, supposing the Church-Turing thesis
  • No, the Church-Turing thesis does not apply to this machine
  • No, Leibniz dreamed of something different
  • No, Leibniz didn't know what he actually wanted
  • No, you won't actually ask such a question from it
  • No, for some other reason

Update: changed "Do you suppose " to "Does " in the question.

[choroba]: yeah, sounds like one of the strings is not flagged as UTF-8
[choroba]: which usually means its input wasn't handled correctly
[Corion]: choroba: Yeah, I think that would be the good solution
[LanX]: I suspect the first string which comes from the DB ...
[LanX]: ... but this part is already in production for a year now
[Corion]: LanX: The "good" approach here would be to use the appropriate DBI parameters to make the driver decode strings properly. But that will have a ripple-on effect of messing up all the places where manual decoding happens ;)
[LanX]: which means albeit being broken UTF8 it'll be handled correctly
[LanX]: and the problem only occurs since we changed the emails to base64
[LanX]: my main problem will be to cnvince my colleagues that our productive code is broken oO ... so in the end I will just make a workaround :-/
LanX hates UTF8 for causing knots in his brain and stomach
