... problems with reflection in C++.
It's a lot of work to add, and the C++ committee is fairly conservative, and don't spend time on radical new features unless they're sure it'll pay off. (A suggestion for adding a module system similar to .NET assemblies has been made, and while I think there's...
Fundamental difference between Hashing and Encryption algorithms
...f (MD5 does this 64 times for each 512bit chunk of data). It then somehow combines the resultant states from all these iterations back together to form the resultant hash.
Now, if you wanted to decode the hash, you'd first need to figure out how to split the given hash into its iterated states (1 ...

Recommended way of making React component/div draggable
I want to make a draggable (that is, repositionable by mouse) React component, which seems to necessarily involve global state and scattered event handlers. I can do it the dirty way, with a global variable in my JS file, and could probably even wrap it in a nice closure interface, but I want to kno...
Two-way encryption: I need to store passwords that can be retrieved

The benefit there, is that any 2 of the keys can be compromised without the data being compromised. If there's a SQL Injection attack, they can get the $userKey, but not the other 2. If there's a local server exploit, they can get $userKey and $serverKey, but not the third $...
