What is the explanation for these bizarre JavaScript behaviours mentioned in the 'Wat' talk for Code
...ray) to a primitive returns its default value, which for objects with a valid toString() method is the result of calling object.toString() (§8.12.8). For arrays this is the same as calling array.join() (§15.4.4.2). Joining an empty array results in an empty string, so step #7 of the addition opera...
Differences and relationship between glActiveTexture and glBindTexture
...lent to this is as follows:
Object *g_objs[MAX_LOCATIONS] = {NULL};
void BindObject(int loc, Object *obj)
{
g_objs[loc] = obj;
}
Textures are interesting; they represent a special case of binding. Many glBind* calls have a "target" parameter. This represents different locations in the OpenG...

It can cover the title. I found this out the hard way and imagine some of you end up reading this page for the same reason.
Use this method instead

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)...

Multiprocessing vs Threading Python [duplicate]
...is usually straightforward
Takes advantage of multiple CPUs & cores
