Sorry the text was submitted before it was complete. =20 While thinking about the implications of Prpofessor McCormick's experience= I had thought about that objection but forgot to include: it only telle u= s about performance at a certain level of experience. Of course we could tell to people who say "Languages don't matter" that since they didn'= t restrict the set to "programmers having graduated" we win and they lose but statisticians don't say that. They say "we don't have data for=20 market-ready programmers. Further study is necessary". I agree that what= matters is what happens when people get paying jobs and employers (and use= rs) have to cope with the consequences of programmers' output. However I think it would be wrong to restrict us to "experienced" programmers: if during first year after university programmers are more productive with language A= and during the rest of their carreers they have identical performance with= A and B then A > B. =20 A final note about randomness: you can tell the color of window shutters i= s decided by house owner and probabilities don't apply. But stastiticians co= nsider that there is some randomeness in the population of a city so 500,0= 01 green shutters and 499,999 red ones vs the opposite is not considered si= gnificative (within the confidence interval or, if you prefer one guy who m= oved to that city) while 200,000 vs 800,000 vs the opposite points to peopl= e having different cultural habits (well outside the confidence interval). = =20 Since the discussion is becoming philosophical and I fear we end boring the= others to death I suggest we continue it in private.
