base64 encoded images in email signatures
...me clients, src="sig.png" will work too.
You'd basically have a multipart/mixed, multipart/alternative, multipart/related message where the image attachment is in the related part.

How can I add reflection to a C++ application?
... a list of all members of T. If we wanted have runtime reflection (ie RTTI mixed with reflection), the compiler would still know all reflected base types. It's quite likely members<T>(T&) would never be instantiated for T=std::string, so the RTTI for std::string or its derived classes need...
Generic method multiple (OR) type constraint
...o the 15th digit I'll return either an object that can go fishing or maybe mix

Break a previous commit into multiple commits
... the commit, but leave the committed files in the index. You can also do a mixed reset by omitting --soft, depending on how close to the final result your initial commit is going to be. The only difference is whether you start with all the changes staged or with them all unstaged.

What is a lambda expression in C++11?

Multithreading: What is the point of more threads than cores?
...e of threads, which is parallelism: to run several separate lines of execution at once. In an 'ideal' system, you would have one thread executing per core: no interruption. In reality this isn't the case. Even if you have four cores and four working threads, your process and it threads will const...
