C/C++ an int value that isn't a number ?!
Can this ever happen ? 3 asserts, where one should activate. int nr = perform_calc(); assert( nr == 0); assert( nr > 0); assert( nr < 0); Can there be a case when the program doesn't activate the asserts on g++ 3.4.4.

64-bit library limited to 4GB?
I'm using an image manipulation library that throws an exception when I attempt to load images > 4GB in size. It claims to be 64bit, but wouldn't a 64bit library allow loading images larger than that? I think they recompiled their C libraries using a 64 bit memory model/compiler but still used unsigned integers and failed upgrade to us...
Object-oriented C++ API for Tokyo Cabinet?
Is there a C++ wrapper for the Tokyo Cabinet API? Obviously I can use the basic C API from C++, but I'd much rather use something that abstracted the raw functions and structures into classes. I'm tempted to write this myself, at least for the bits of the API that I'd want to use, but it'll save time if there's one already. I checked th...
Why does a quoted string match bool method signature before a std::string?
Given the following methods: // Method 1 void add(const std::string& header, bool replace); //Method 2 void add(const std::string& name, const std::string& value); It would appear that the following code will end up calling method 1 instead of method 2: something.add("Hello", "World"); I ended up creating another method that looks...
