Well, the point is that e.g. I know people who tried to do similar apps in Python and it was too slow, they abandoned it and went to C++. That's the reason why I was primarily exploring statically-compiled languages. Julia *might* be interesting since it is higher-level language with fantastic, close to C performance when one helps compiler by annotating data types. In short, I want to avoid fiddling with low-level languages, otherwise it would be simple to just use C/GTK or C++/Qt. (Java could probably also do the job, but I simply do not like it.) For the most critical part of the application, I anyway plan to use 3rd party C lib which does calculate planetary ephemeris, but for the custom libs using it, I want to use higher-level and type-safer language. > In any case there are always 3 rules, profile, profile and profile. > When it comes to performance assume nothing.

When I say 'business' app, it is most in the sense of typical 'desktop outlook', while the app itself is falling more into 'science' app, but it depends how one sees astronomy/astrology. :-) > Pharo libraries dont get irrelevant because the language is so simple > it barely changes and the changes usually dont brake compatibility.

Right, it's just that Julia provides more 'traditional' dev work-flow, while with Pharo one has to unwrap one's head a bit. :-) > GUI wise you can do some pretty awesome stuff with morphic.
