What would cause an algorithm to have O(log n) complexity?
...t a log term to show up in big-O notation. Here are a few:
Repeatedly dividing by a constant
Take any number n; say, 16. How many times can you divide n by two before you get a number less than or equal to one? For 16, we have that
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2
2 / 2 = 1
Notice that this...

As a side note, I'm using the full dataset that Ivo provided a link to in his original question. It's a series of rar files (one-per-dog) each containing several different experiment runs stored as ascii arrays. Rather than try to...
In what order are Panels the most efficient in terms of render time and performance?
...l to accommodate stretching using alignments (or Auto in the case of the Grid) and then the number of children which are stretched or auto-sized. The performance of the Arrange pass is affected by the complexity of the interaction between layout location of different children and then of course the...
RESTful Authentication
...r, which will persist (there is no LogOut-like feature here), some server-side additional CPU consumption, and the fact that the user-name and password are transmitted (over HTTPS) into the Server (it should be more secure to let the password stay only on the client side, during keyboard entry, and ...
Scala: Abstract types vs generics
...uld argue that this distinction is fairly arbitrary.
The Scala Way
We decided to have the same construction principles for all three sorts of members.
So you can have abstract fields as well as value parameters.
You can pass methods (or "functions") as parameters, or you can abstract over them.

Points to Consider
When used for the same thing, here is how they compare using the original question's "Points to Consider":
Read/write speed: Both are extremely fast. Benchmarks vary by workload, versions, and many other factors but gen...

Logical operators for boolean indexing in Pandas
...are designed to work with scalars. So Pandas had to do one better and override the bitwise operators to achieve vectorized (element-wise) version of this functionality.
So the following in python (exp1 and exp2 are expressions which evaluate to a boolean result)...

What's the difference between eval, exec, and compile?
...nd exec is used to execute dynamically generated Python code only for its side effects.
eval and exec have these two differences:
eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.
