Java 32-bit vs 64-bit compatibility
Yes, Java bytecode (and source code) is platform independent, assuming you use platform independent libraries. 32 vs. 64 bit shouldn’t matter.

Internet Explorer 11 disable “display intranet sites in compatibility view” via meta tag not working

Fragments onResume from back stack
For a lack of a better solution, I got this working for me: Assume I have 1 activity (MyActivity) and few fragments that replaces each other (only one is visible at a time). In MyActivity, add this listener: getSupportFragmentManager().addOnBackStackChangedListener(getListener()); (As you can see I’m using the compatibility package). getListener implementation: private OnBackStackChangedListener getListener() { OnBackStackChangedListener … Read more
Logging framework incompatibility
You are mixing the 1.5.6 version of the jcl bridge with the 1.6.0 version of the slf4j-api; this won’t work because of a few changes in 1.6.0. Use the same versions for both, i.e. 1.6.1 (the latest). I use the jcl-over-slf4j bridge all the time and it works fine.

Can I install Python 3.x and 2.x on the same Windows computer?
The official solution for coexistence seems to be the Python Launcher for Windows, PEP 397 which was included in Python 3.3.0. Installing the release dumps py.exe and pyw.exe launchers into %SYSTEMROOT% (C:\Windows) which is then associated with py and pyw scripts, respectively. In order to use the new launcher (without manually setting up your own … Read more
