Re: [Pharo-users] Is there a way to stop arrays sorting automatically?

Would be good to have tests showing the problem. Did you check if such method is not already covered (even by a bad test)?

I prefer that we do not lose again a lot of engineering time to migrate and update our process. We have too many fronts open right now. We should really pay attention because starting something is super easy finishing it super difficult. Stef

The pipeline was not really first class in lukas work. It was added incrementally. Now we have a real architecture.

Offray Vladimir Luna CÃ¡rdenas-2 wrote > Now they're in the SThub and also in the PDF Manual linked there. Ah, okay I see they are updated for 6.1, but they still use Gofer. Also, IIRC (I moved all my development to git a while ago now) the best practice is to always keep the most up-to-date ConfigurationOf in the canonical repo (i.e. yours) and then /copy/ it to the relevant platform metaRepoForXyz's. Otherwise, in my experience one invites chaos because people are downloading variously out-of-date configs from multiple sources (like me last night spending time reporting already-fixed bugs; don't worry I'm not upset!). See my previous post for the preferred script that should be expected to work on /any/ supported platform. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

That has improved a lot. I have bookmarked the site, and I now have a reason to learn iceberg. Out of curiosity, and perhaps this has been answered elsewhere, why are we using fogbugz for issue tracking, rather than github's issue tracker? I know nothing much about either of them. I am just curious if fogbugz is much better? Cheers Andy
