Generate a random double in a range
...
This is generally correct, but beware of its limits. If you do double rangeMax= Double.MAX_VALUE; and double rangeMin= -rangeMax; you will always get an infinite value in return. You might want to check for Double.valueOf(rangeMax-range...
What is uintptr_t data type
...signed integer type that is capable of storing a data pointer. Which typically means that it's the same size as a pointer.
It is optionally defined in C++11 and later standards.
A common reason to want an integer type that can hold an architecture's pointer type is to perform integer-specific ope...

sab[1].lLbou...
Have Grunt generate index.html for different setups
...awesome bit of code, the Yeoman grunt-usemin is a more robust than I personally need.
NOTE: I just discovered the above listed tasks today, so I might be missing a feature and/or my process may change down the road. For now, I'm loving the simplicity and features that grunt-preprocess and grunt-env...

This memory management whitepaper (PDF) may help explain what's going on.

How to retrieve an element from a set without removing it?
...r(s)) only exceeds list(s)[0] by three characters and is otherwise dramatically superior in both time and space complexity. So, while the claim of "least code" is trivially true, it's also trivially true that this is the worst possible approach. Even manually removing and then re-adding the removed ...
PEP 8, why no spaces around '=' in keyword argument or a default parameter value?
...
I guess that it is because a keyword argument is essentially different than a variable assignment.
For example, there is plenty of code like this:
kw1 = some_value
kw2 = some_value
kw3 = some_value
some_func(
1,
2,
kw1=kw1,
kw2=kw2,
kw3=kw3)
As you see, it mak...

The recording uses cd quality (44100 samples), stereo (2 channels) linear pcm. Beware: if you wa...
