Generate Random numbers without using any external functions

based on previous ones so in theory they are completely deterministic. The only randomness is guaranteed by providing a good seed..

Does C++ support 'finally' blocks? (And what's this 'RAII' I keep hearing about?)

http://stackoverflow.com/questions/161177/does-c-support-finally-blocks-and-whats-this-raii-i-keep-hearing-about

or VB.NET you may recognize that RAII is similar to .NET deterministic destruction using IDisposable and 'using' statements . Indeed.. are very similar. The main difference is that RAII will deterministically release any type of resource including memory. When implementing.. in .NET even the .NET language C CLI resources will be deterministically released except for memory. In .NET memory is not be deterministically..

Static variable initialization?

Garbage Collection in C++ — why?

Is a C++ compiler allowed to emit different machine code compiling the same program?

What are some reasons a Release build would run differently than a Debug build

http://stackoverflow.com/questions/312312/what-are-some-reasons-a-release-build-would-run-differently-than-a-debug-build

leads to funny values and random crashes but as often to deterministic crashes that require an apparently unrelated command to be executed..

When and why will an OS initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete?

http://stackoverflow.com/questions/370195/when-and-why-will-an-os-initialise-memory-to-0xcd-0xdd-etc-on-malloc-free-new

What could cause a deterministic process to generate floating point errors

http://stackoverflow.com/questions/968435/what-could-cause-a-deterministic-process-to-generate-floating-point-errors

could cause a deterministic process to generate floating point errors Having already read.. same hardware compiled with the same compiler should be deterministic. I'm looking at a case where this isn't true and trying to determine.. or strict. Could this make a floating point process non deterministic Are there other optimisations etc that could lead to this behaviour..
