When should I use Lazy?
...he fastest, because it populated its properties during instantiation. (At least that is what it should have done but why was it's instantiation result so much quicker than a single linear interpolation? When exactly is it doing these interpolations?)
Unfortunately it looks like there is some auto...
Determine the type of an object?
...o that" part. But indeed to tell someone not to do something you should at least explain why not and I figured this was a relevant opportunity to do just that. I meant for the cautious method to look ugly and illustrate why they might not want to do
What is the difference between statically typed and dynamically typed languages?
...
This makes a lot of sense. I think it explains at least the reasoning behind the names much better than other answers here.

How do I call one constructor from another in Java?
...
Initialization should proceed from least to greatest - I would never have a default constructor call up the chain to a multi-parameter constructor. What needs to happen is that all constructors call either the default or a constructor with less parameters.

Synchronization vs Lock
..., or wait / notify
However, concurrency is tricky, and most people get at least some parts of it wrong, making their code either incorrect or inefficient (or both).
The concurrent API provides a higher-level approach, which is easier (and as such safer) to use. In a nutshell, you should not need t...
What scalability problems have you encountered using a NoSQL data store? [closed]
...job there... 0o).
In a summary, CouchDB was surely the best choice (or at least a better choice than MySQL) for this subproject and it does its job well.

Why don't structs support inheritance?
...
At least by preventing struct inheritance we have a separate keyword and can more easily say "structs are special", as opposed to having a "random" limitation in something that works for one set of things (classes) but not for a...
Why is there no xrange function in Python3?
...0 in xrange(1000000) and that caused it to iterate the whole xrange (or at least the first 30% of it), so we had to explain why that was a bad idea, even though it looks so pythonic. Now, it is pythonic.

Why is unsigned integer overflow defined behavior but signed integer overflow isn't?
...o platform that can run C at all should have much trouble supporting it at least moderately efficiently. The extra overhead would be sufficient that code shouldn't use such a type when wrapping behavior isn't required, but most operations on two's complement integers are identical to those on an un...
Find unique rows in numpy.array
...
unique_a = np.unique(b).view(a.dtype).reshape(-1, a.shape[1])
Also, at least on my system, performance wise it is on par, or even better, than the lexsort method:
a = np.random.randint(2, size=(10000, 6))
%timeit np.unique(a.view(np.dtype((np.void, a.dtype.itemsize*a.shape[1])))).view(a.dtype)...
