Is MATLAB OOP slow or am I doing something wrong?
I'm em>x m>perimenting with MATLAB OOP , as a start I mimicked my C++'s Logger classes and I'm putting all my string helper functions in a String class, thinking it would be great to be able to do things like a + b , a == b , a.find( b ) instead
of strcat( a b ) , strcmp( a, b ) , retrieve first...
Matplotlib connect scatterplot points with line - Python
...nse for the points, which you can still plot via scatter, as per my first em>x m>ample. The question does not say anything about a varying line thickness or color, so I think your criticism is a bit unfair, really.

How em>x m>actly does a generator comprehension work?
...
Do you understand list comprehensions? If so, a generator em>x m>pression is like a list comprehension, but instead of finding all the items you're interested and packing them into list, it waits, and yields each item out of the em>x m>pression, one by one.
>>> my_list = [1, 3, 5, 9,...
In PHP what does it mean by a function being binary-safe?
...ry data (i.e. strings containing non-ASCII bytes and/or null bytes).
For em>x m>ample, a non-binary-safe function might be based on a C function which em>x m>pects null-terminated strings, so if the string contains a null character, the function would ignore anything after it.
This is relevant because PHP d...

Pythonic way of checking if a condition holds for any element of a list

any():
if any(t < 0 for t in m>x m>):
# do something
Also, if you're going to use "True in ...", make it a generator em>x m>pression so it doesn't take O(n) memory:
if True in (t < 0 for t in m>x m>):

How to position a DIV in a specific coordinates?

Script its left and top properties as the number of pim>x m>els from the left edge and top edge respectively. It must have position: absolute;

Simple logical operators in Bash

(…) parentheses indicate a subshell. What's inside them isn't an em>x m>pression like in many other languages. It's a list of commands (just like outside parentheses). These commands are em>x m>ecuted in a separate subprocess, so any redirection, assignment, etc. performed inside the parentheses has ...
Difference between Lookup() and Dictionary(Of list())
...esent in a lookup, you get an empty sequence back instead of a KeyNotFoundEm>x m>ception. (Hence there's no TryGetValue, AFAICR.)
They're likely to be equivalent in efficiency - the lookup may well use a Dictionary<TKey, GroupingImplementation<TValue>> behind the scenes, for em>x m>ample. Choose...
