How do I convert between big-endian and little-endian values in C++?
...s with plain integers as these may or not may be in the host machines byte-order. You can get little-endian floats on big-endian machines and vice versa.
Other compilers have similar intrinsics as well.
In GCC for example you can directly call some builtins as documented here:

Common elements comparison between 2 lists
...at when I ended up on this page, it was important to preserve the original order of the elements for the post-filtered elements. This method loses the order, whereas the list comprehension method preserves the order. Important if anyone needs to consider this. Thanks.

What's wrong with using $_REQUEST[]?
...roduce.
You can change this behaviour to the much more sensible GP (no C) order with the request_order config in PHP 5.3. Where this is not possible, I personally would avoid $_REQUEST and, if I needed a combined GET+POST array, create it manually.

What is a “cache-friendly” code?
... algorithm design
Whenever possible, try to adapt your data structures and order of computations in a way that allows maximum use of the cache. A common technique in this regard is cache blocking (Archive.org version), which is of extreme importance in high-performance computing (cfr. for example AT...
What is the meaning of “non temporal” memory accesses in x86
...Therefore non-temporal stores must be followed by an SFENCE instruction in order for their results to be seen by other processors in a timely fashion.
When data is produced and not (immediately) consumed again, the fact that memory store operations read a full cache line first and then modify the c...
Remove duplicate dict in list in Python

Edit: If you want to preserve ordering, the one-liner above won't work since set won't do that. However, with a few lines of code, you can also do that:
l = [{'a': 123, 'b': 1234},
{'a': 3222, 'b': 1234},
{'a': 123, 'b': 1234}]

Returning 'IList' vs 'ICollection' vs 'Collection'
...erface.
IList<T> is essentially an ICollection<T> with random order-based access.
In this case you should decide whether or not your results require list semantics such as order based indexing (then use IList<T>) or whether you just need to return an unordered "bag" of results (t...
