C/C++ with GCC: Statically add resource files to executable/library
...t.
I have used objcopy (GNU binutils) to link the binary data from a file foo-data.bin into the data section of the executable:
objcopy -B i386 -I binary -O elf32-i386 foo-data.bin foo-data.o
This gives you a foo-data.o object file which you can link into your executable. The C interface looks s...
Are strongly-typed functions as parameters possible in TypeScript?
...type must be "function that accepts a number and returns type any":
class Foo {
save(callback: (n: number) => any) : void {
callback(42);
}
}
var foo = new Foo();
var strCallback = (result: string) : void => {
alert(result);
}
var numCallback = (result: number) : void =&g...
When monkey patching an instance method, can you call the overridden method from the new implementat
...nce
So, if at all possible, you should prefer something like this:
class Foo
def bar
'Hello'
end
end
class ExtendedFoo < Foo
def bar
super + ' World'
end
end
ExtendedFoo.new.bar # => 'Hello World'
This works, if you control creation of the Foo objects. Just change every ...

How does “this” keyword work within a function?

As a Method
A method is a function that's attached to an object
var foo = {};
foo.someMethod = function(){
alert(this);
}
When invoked as a method, this will be bound to the object the function/method is a part of. In this example, this will be bound to foo.

如果你需要实现一个数组用来存放(Foo,Bar)的对象，尝试分解为Foo[]与Bar[]要比(Foo,Bar)好很多。(当然，为了某些好的API的设计，可以适当做一些妥协。但是在自己的代码内部，你应该多多使用分解后的容易。

Passing arguments to “make run”
...gn followed by the name of the variable in parentheses or braces: either $(foo)' or ${foo}' is a valid reference to the variable `foo'." and proceeds to give examples where only $() is used. Ah well.

Send an Array with an HTTP Get
...ffers a dedicated method to obtain multiple parameter values as an array.
foo=value1&foo=value2&foo=value3
String[] foo = request.getParameterValues("foo"); // [value1, value2, value3]
The request.getParameter("foo") will also work on it, but it'll return only the first value.

TypeScript function overloading
...Script, you only have one implementation with multiple signatures.
class Foo {
myMethod(a: string);
myMethod(a: number);
myMethod(a: number, b: string);
myMethod(a: any, b?: string) {
alert(a.toString());
}
}
Only the three overloads are recognized by TypeScript as po...
