C++ performance vs. Java/C#
... your c++ compiler will offer for different architectures is usually x86, x64, ARM and whatnot. Now you can tell it to use specific features (say SSE2) and if you're lucky it'll even generate some backup code if that feature isn't available, but that's about as fine-grained as one can get. Certainly...

The pitfall: as of July 2015 the above compiles with MinGW-64 5.1.0 with
-pedantic-errors, and,
testing with the online compilers at gcc.godbolt.org/, also with clang 3.0
and clang 3.2, but not with clang 3.3, 3.4.1, 3.5.0, 3.5.1, 3.6 (rc1) or
3.7 (experimental). And important for th...

Logging best practices [closed]
...ase coming from a platform flexibility (desktop .Net/Compact Framework, 32/64-bit) point of view.
However, wrapping it in a private-label API is a major anti-pattern. log4net.ILogger is the .Net counterpart of the Commons Logging wrapper API already, so coupling is already minimized for you, and s...

You must follow the instructions to the letter.
Do not try to use java 64 bit. It will not compile the KitchenSink 1.4.0 demo application. (1.3 works OK!)
You must put files directly on the C drive as long pathnames will make the external program not receiving all command line parameters if they...
