Why is “except: pass” a bad programming practice?
...
Executing your pseudo code literally does not even give any error:
try:

except:
pass
as if it is a perfectly valid piece of code, instead of throwing a NameError. I hope this is not what you want.

How can I create a temp file with a specific extension with .NET?
...clouds. The approach is: generate a random file name, then create it if it doesn't exist. So just help him code that nicely. All this talk about pseudo-random generators and universally unique numbers is totally unnecessary.

...
This does not work for me. Is there a way to make it work if the SharedPreference is used across two apps? I have one app making the change and another reacting to it. The only way I got it to work was to use the IPC model and ...

If the difference was bigger, I would raise an issue in the NumPy bug tracker. :) I prefer more explicit and clearer code, for such a small difference...
