Difference between Bridge pattern and Adapter pattern
...ions of a data store: one is efficient in space, the other is efficient in raw performance... and you have a business case for offering both in your app or framework.
In terms of your question, "where I can use which pattern," the answer is, wherever it makes sense for your project! Perhaps conside...
Is this a “good enough” random algorithm; why isn't it used if it's faster?
...
+1 for numerical data - although looking on raw numbers can be misleading as it does not mean that they have statistically significant difference.

make_unique and perfect forwarding
..._ptr<A> &&, std::unique_ptr<B> &&). Having two raw news that are unsequenced with respect to one another means that if one new expression fails with an exception, the other may leak resources. As for why there's no make_unique in the standard: It was just forgotten. (This...
Fastest way to serialize and deserialize .NET objects
...cases where ProtoBuf and NetSerializer are well-suited to, but in terms of raw performance for at least relatively simple objects... BinaryFormatter is significantly more performant, by at least an order of magnitude.
YMMV.

Is modern C++ becoming more prevalent? [closed]
...ak of is clearly visible there: the older code is often "C with classes" - raw pointers, char* strings and use of associated C functions, arrays etc; newer code uses ATL smart pointers and such to manage resources, but still sticks to hand-coded loops most of the time, and iterator is a rare sight; ...

Maximum Java heap size of a 32-bit JVM on a 64-bit OS
...
32-bit JVMs which expect to have a single large chunk of memory and use raw pointers cannot use more than 4 Gb (since that is the 32 bit limit which also applies to pointers). This includes Sun and - I'm pretty sure - also IBM implementations. I do not know if e.g. JRockit or others have a larg...
How can I improve my paw detection?
...the data for each paw with [data[x] for x in data_slices]. Instead, we'll draw a rectangle based on these slices, which takes slightly more work.
The two animations below show your "Overlapping Paws" and "Grouped Paws" example data. This method seems to be working perfectly. (And for whatever i...
