| | Sooo... Every DLL injection result I've read so far only uses a pre-made DLL, loads it into another process and says "darn I'm good." They do absolutely NOTHING useful and a couple of them are rip-offs of one another only using a different programming language. Google has failed me! Once … |

| | I've found that often in my code I have a need for primitive variables protected with synchronization objects such as a boost::mutex, and I was wondering if the boost library provides a template similar to this one I'm considering, based on the C# property methods get/set: [code] template<typename var_type> class … |
| | Do any of you (reading this) know of a good learning resource for implementing a neural network, instead of papers describing the theory?

| | [url]http://www.boost.org/doc/libs/1_46_0/libs/smart_ptr/shared_ptr.htm#ThreadSafety[/url] This section somewhat confused me, in my code I have a matrix of shared_ptr's pointing to an entirely thread-safe class. But the shared_ptr documentation says it is only as thread-safe as the built-in C++ types. Does this mean that if I read/write to my thread-safe class using shared_ptr's at … |
