woosh!
it's funny because scala IS a front end to java. yes, it was to the same 1.6 jvm op considered stalled. then one wonders: what do developers actually demand from a vm? what's the problem if it works, is solid, stable and predictable and doesn't get some new fancy (and mostly unneeded) goodies in a while?
yeah, well, if you want to share unrelated personal experiencies, when doing client stuff i use pure client frameworks (angular nowadays for the most part) as opposed to full server/client stacks which in my view don't cut it, and i like them to be focused and simple. regarding ides i've used all of them but i'm perfectly fine with emacs and a console. if your code needs a specific ide to work on it then it's pretty low value for me. yes, java projects tend to be file spewing monsters and i ocassionally fire up some ide (eclipse or intellij, any will do), but you'll have a hard time convincing me to set up visual studio just to inspect or run some of your c# code, i'll probably point you in the general direction away from my lawn.
ruby was completely unecessary, didn't bother with it and i'm glad it passed away with the hype (as expected) leaving just a legacy of crappy apps that need to be rewritten (or forgotten), c# was also redundant and late (unless you were a windows only freak) glad to hear they now want to mature and open up a bit, php is handy for small quick apps but nothing more (no matter how much they want to revamp it now), python is actually very cool (although i seldom have opportunity to use it) and go ... well, go seems weird on purpose, it has some nice features but what was the need to screw up so much of the syntax for no reason? sick of evangelists, i think i'll pass, too ...
