How to create a private class method?
...
I too, find Ruby (or at least my knowledge of it) short of the mark

class Frob
attr_reader :val1, :val2
Tolerance = 2 * Float::EPSILON

Change R default library path using .libPaths in Rprofile.site fails to work
...kages):
.libPaths( c( "~/userLibrary" , .libPaths() ) )

How do I set the figure title and axes labels font size in Matplotlib?
...ng, you might find the ax.xaxis.label.set_size() easier to remember, or at least easier to find using tab in an ipython terminal. It seems to need a redraw operation after to see the effect. For example:

One could rename __call__ to something else and pass a bound method, but that makes the code creating the thread slightly less obvious, and doesn't ...
How do I match any character across multiple lines in a regular expression?
...

Difference between modes a, a+, w, w+, and r+ in built-in open function?
...the end of file - ignores any seek movements.
BTW. interesting behavior at least on my win7 / python2.7, for new file opened in a+ mode:
write('aa'); seek(0, 0); read(1); write('b') - second write is ignored
write('aa'); seek(0, 0); read(2); write('b') - second write raises IOError
