Setting the correct encoding when piping stdout in Python
...ad and permanent choice of encoding on stdout at startup time, might be in order to prevent any badly encoded stuff coming out later on. Or changing it is just an unimplemented feature, in which case allowing the user to change it later on would be a reasonable Python feature request.

What does the C++ standard state the size of int, long type to be?
...luates to a number of bits high enough to contain required ranges, and
the ordering of type is still valid (e.g. sizeof(int) <= sizeof(long)).
Putting this all together, we are guaranteed that:
char, signed char, and unsigned char are at least 8 bits
signed short, unsigned short, signed int, an...
Can't access object property, even though it shows up in a console log
...he category key, because it can have more than one category object. So, in order to get the 'name' key I used this:
var_name = obj_array.terms.category[0].name
And That does the trick.
Maybe it's too late for this answer, but I hope someone with the same problem will find this as I did before fi...
How does std::forward work? [duplicate]
...uld be made.
set(makeAndFillVector()); // set will still make a copy
In order to avoid this copy, you need "perfect forwarding", which would result in optimal code every time. If you're given an lvalue, you want your function to treat it as an lvalue and make a copy. If you're given an rvalue, yo...

Why does GCC generate 15-20% faster code if I optimize for size instead of speed?
...cle (and I believe a version of this also appeared in CACM) shows how link order and OS environment size changes alone were sufficient to shift performance significantly. They attribute this to alignment of "hot loops".
