How do I install PyCrypto on Windows?
...
If you don't already have a C/C++ development environment installed that is compatible with the Visual Studio binaries distributed by Python.org, then you should stick to installing only pure Python packages or packages for which a Windows binary is available.
Fortunately, there are Py...

...
The configuration file is called applicationhost.config.
It's stored here:
My Documents > IIS Express > config
usually, but not always, one of these paths will work

Class with Object as a parameter
... Table to be a new-style class (as opposed to "classic" class).
In Python3 all classes are new-style classes, so this is no longer necessary.
New style classes have a few special attributes that classic classes lack.
class Classic: pass
class NewStyle(object): pass
print(dir(Classic))
# ['__doc__...
Java 8 Streams: multiple filters vs. complex condition
...t reliably. The underlying object structure might differ but that’s no challenge to the hotspot optimizer. So it depends on other surrounding conditions which will yield to a faster execution, if there is any difference.
Combining two filter instances creates more objects and hence more delegatin...
Transposing a NumPy array
...of a 1D array is still a 1D array! (If you're used to matlab, it fundamentally doesn't have a concept of a 1D array. Matlab's "1D" arrays are 2D.)
If you want to turn your 1D vector into a 2D array and then transpose it, just slice it with np.newaxis (or None, they're the same, newaxis is just mor...
Create Generic method constraining T to an Enum
... You don't gain much by including the other interfaces because almost all of the built-in value types implement all of those interfaces. This is especially true for constraints on a generic extension method, which is extremely handy for operating on enums, except for the fact that those extensi...

Why does intellisense and code suggestion stop working when Visual Studio is open?
...not (after a period of time, anywhere from 5 minutes to over an hour) and all of a sudden, no more code suggestions or intellisense. Both seem to stop working completely at the same time.

What's the difference between MyISAM and InnoDB? [duplicate]
...es made by two or more DML operations handled as single unit of work, with all of the changes either applied, or all the changes reverted) then you would choose the InnoDB engine, since these features are absent from the MyISAM engine.
Those are the two biggest differences. Another big difference is...
Is there any advantage of using map over unordered_map in case of trivial keys?
... unordered_map.
Something else to keep in mind is that unordered_map generally uses more memory. map just has a few house-keeping pointers, and memory for each object. Contrarily, unordered_map has a big array (these can get quite big in some implementations), and then additional memory for each ob...
