No, you cannot. In Python, all data (classes, methods, functions, etc) defined in C extension modules (including builtins) are immutable. This is because C modules are shared between multiple interpreters in the same process, so monkeypatching them would also affect unrelated interpreters in the same process. (Multiple interpreters in the same process are possible through … Read more
Yes. In general any literal string, identifier, or other constant string in JS source is interned. However implementation details (exactly what is interned for instance) varies, as well as when the interning occurs. Note that a string value is not the same as a String Object though, String Objects are not interned because that would … Read more
Thread-safe code is code that will work even if many Threads are executing it simultaneously. http://mindprod.com/jgloss/threadsafe.html
It is a term used in dynamic languages that do not have strong typing. The idea is that you don’t need a type in order to invoke an existing method on an object – if a method is defined on it, you can invoke it. The name comes from the phrase “If it looks like … Read more
Contrary to what others are saying, overloading by return type is possible and is done by some modern languages. The usual objection is that in code like int func(); string func(); int main() { func(); } you can’t tell which func() is being called. This can be resolved in a few ways: Have a predictable … Read more
Statically typed languages A language is statically typed if the type of a variable is known at compile time. For some languages this means that you as the programmer must specify what type each variable is; other languages (e.g.: Java, C, C++) offer some form of type inference, the capability of the type system to … Read more
In C, arrays can be indexed like so: a[10] which is very common. However, the lesser known form (which really does work!) is: 10[a] which means the same as the above.
I could think of following two ways: You will need to use Facebook Graph API to monitor posts by user https://developers.facebook.com/docs/graph-api/reference/v3.0/post. But for that, the user should give permission to your app or the post should be public. Graph API SDK is available for PHP, Javascript, Android, and IOS. Another way I could think is … Read more
even I was in the same situation as you.. after few days of research, I concluded with nodejs being the best option.. quite new but promising.. and fits in all requirements you mentioned..
Some more things function pointers are often used for: Runtime polymorphism: You can define a structure that encapsulates a function pointer, or a pointer to a function table. This enables you to call the specified function at runtime, even for a type of client object that did not exist when your library was written. You … Read more
