Numpy first occurrence of value greater than existing value
...
As hinted at in the above comment, this answer is off by one if N/2 is not in aa. The correct form would be np.searchsorted(aa, N/2, side='right') (without the +1). Both forms give the same index otherwise. Consider the test case of N being odd (and N/2.0 to force float if using py...
java.util.Date to XMLGregorianCalendar

Why is “using namespace std;” considered bad practice?
...and you can call Blah() from Foo and Quux() from Bar without problems. But one day you upgrade to a new version of Foo 2.0, which now offers a function called Quux(). Now you've got a conflict: Both Foo 2.0 and Bar import Quux() into your global namespace. This is going to take some effort to fix, e...

How may I sort a list alphabetically using jQuery?
...
One problem that I found with this approach is that, since it's only the text that's being moved around, if you associate data to the DOM nodes using jQuery.data prior to sorting, those associations are now pointing to the wr...
