Transposing a NumPy array
...rally speaking though, you don't ever need to worry about this. Adding the extra dimension is usually not what you want, if you're just doing it out of habit. Numpy will automatically broadcast a 1D array when doing various calculations. There's usually no need to distinguish between a row vector a...
Non-Relational Database Design [closed]
...DBs are a massive win, and the drawbacks of less flexible queries and some extra code for data validation seems a small price to pay.
Have you hit your head against anything that seems impossible?
Not yet. Map/reduce as a means of querying a database is unfamiliar, and requires a lot more thinking...

What is the pythonic way to detect the last element in a 'for' loop?
...t depends on what you are trying to do. For example, if you are building a string from a list, it's naturally better to use str.join() than using a for loop “with special case”.
Using the same principle but more compact:
for i, line in enumerate(data_list):
if i > 0:
between_i...

Efficiency of purely functional programming
... for problems that require a greater running time, it is possible that the extra O(log n) factor seen in the linear problem may be able to be "absorbed" in the process of extra operations necessary for algorithms with greater running times. These clarifications and open questions are explored briefl...
Purpose of Trigraph sequences in C++?
...h less dangerous since they get processed as tokens, so a digraph inside a string literal won't get interpreted as a digraph.
For a nice education on various fun with punctuation in C/C++ programs (including a trigraph bug that would defintinely have me pulling my hair out), take a look at Herb Sut...
