Why does C++11's lambda require “mutable” keyword for capture-by-value, by default?
...
This is a good point. I totally agree. In C++0x though, I don't quite see how the default helps enforce the above. Consider I am on the receiving end of the lambda, e.g. I am void f(const std::function<int(int)> g). How am I guaranteed ...
What is the difference between localStorage, sessionStorage, session and cookies?
...ocalStorage only allow you to store strings - it is possible to implicitly convert primitive values when setting (these will need to be converted back to use them as their type after reading) but not Objects or Arrays (it is possible to JSON serialise them to store them using the APIs). Session stor...
PHP Array to CSV
I'm trying to convert an array of products into a CSV file, but it doesn't seem to be going to plan. The CSV file is one long line, here is my code:

Performance optimization strategies of last resort [closed]
...tors of floats. Changing the code to carry around the extra empty slot and converting the calculation to floating point from fixed point allowed for a slightly less-accurate but much faster result.

Why does C++11 not support designated initializer lists as C99? [closed]
...
In other words, designated initializers support a programming style where internals are exposed, and the client is given flexibility to decide how they want to use the type.
C++ is more interested in putting the flexibility on the side of the designer of a type instead, so designers can make it e...
How can I use interface as a C# generic type constraint?
...
The closest you can do (except for your base-interface approach) is "where T : class", meaning reference-type. There is no syntax to mean "any interface".
This ("where T : class") is used, for example, in WCF to limit clients to service contracts (interfaces).

Function pointers, Closures, and Lambda
I am just now learning about function pointers and, as I was reading the K&R chapter on the subject, the first thing that hit me was, "Hey, this is kinda like a closure." I knew this assumption is fundamentally wrong somehow and after a search online I didn't find really any analysis of this compari...
