I wonder why Django doesn't have the same strength (both technically and community) as Rails ? I think the philosophy "Everything is an object" makes sense actually, and in combination with functional programming built-in really makes Ruby is perfect choice for non-professional programmer (even woman) to love coding.
What the fuck is wrong with you?
To begin the migration, we needed to move from Python 2.6 (which is the default on our CentOS6 production boxes) to Python 2.7. This transition is actually rather hard. We can't use the packages provided in CentOS base or EPEL, because they are all complied against Python 2.6. To re-produce all of our package requirements would require us to either build new packages of the compiled libraries (such as MySQL-python, python-crypto, PyYAML, etc), or load down our production environment with a compiler and all of the development libraries.
Migrating from Python 2.7 to Python 3 would have required a nearly identical effort (there's not a lot of Python 3 packages for CentOS, in particular the packages that we need for our application).
Frankly, it's just not worth that effort at this time. Python 2.6 is the default environment, there's solid package support for it, and it just plain works. We'll make that dive when Python 3 becomes the default for CentOS (scheduled for 8 or 9, IIRC), and probably not before.
What about make python 3 fully retro-compatible with python 2.7 with the help of magic imports
from __past__ import byte_strings
from __past__ import except_tuple
I used Python 3 for the first time a few days ago (I've been programming in Python for 18 years). When I used python heavily (I've switched back to C++ and now Go) I depended a lot on a small number of really good libraries- ElementTree, NumPy, SciPy, etc. Unless/until all of those get ported to Python 3 (along with hundreds of other programs), and those ports are considered Correct (in the QA validation sense), it's…
Something that might help is OS vendors shipping with 3.x installed, rather than 2.x most seem to. OS X ships with 2.7.5. For a casual python user, sticking with what is there and working is safe, especially when the benefits of 3.x are unclear.

> You could analogize it to Apple with OS 9 -> OS 10.9, versus Microsoft with people still running XP No, you couldn't. The difference in upgrade rates between Windows and OS X is primarily due to their differing customer bases. Windows is very popular in enterprise, which avoids unnecessary upgrades in order to ensure compatibility with in-house software. OS X, however, has almost no presence in enterprise, and cons…
Mags have a significant presence in enterprise these days.

I don't share Alex's concern. The migration to Python 3.X is a slow, but in my opinion sure process. Already many of my small internal programs run on Python 3.4, and I believe that in 1-2 years from now I'll be writing most new Django client projects in Python 3.4 (hopefully running on Pypy3).

Perl 6 is vaporware. Python 3 is here, it's widely supported, it's faster than Python 2.7, and while Guido didn't do us any favors with his migration strategy, I don't see what the big deal is. Python 3.3 makes writing code that is compatible with both almost trivial. People aren't using Python 3 enough because it's not the default in Debian/Ubuntu. That's about to change with Ubuntu 14.04. I expect that to tip the s…
> Perl 6 is vaporware Perl 6 is not vaporware, you can run it today: http://perl6.org/compilers/features Is it 100% feature complete or fast? No. But there working code and new, stable releases on a monthly basis.
If it's not feature complete it's vaporware.
