In the following code let us assume for simplicity that float and uint32_t have the same size. void fun(uint32_t* u, float* f) { float a = *f *u = 22; float b = *f; print("%g should equal %g\n", a, b); } u and f have different base type, and thus the compiler can a...

If we have two pointer arguments of the same type, the compiler can't make any assumption and will always have to assume that the change to *e may change *f: void fun(float* e, float* f) { float a = *f *e = 22; float b = *f; print("is %g equal to %g?\n", a, b); } f...

In fluent programming style you return this from fluent (setter) methods that would return nothing in non-fluent programming style. This allows you to chain the different method calls which makes your code shorter and easier to handle for the developers. Consider this non-fluent code: public clas...

To check if a value exits in a WeakSet, use the .has() method. const obj1 = {}, obj2 = {}; const weakset = new WeakSet([obj1]); console.log(weakset.has(obj1)); // true console.log(weakset.has(obj2)); // false

The name Smalltalk usually refers to ANSI Smalltalk or Smalltalk 80 (of which the first is based on). While most implementations are close to the standard, they vary in different aspects (usually referred to as dialects). Each implementation has it's own method of installation.

c++17 C++17 introduces int std::uncaught_exceptions() (to replace the limited bool std::uncaught_exception()) to know how many exceptions are currently uncaught. That allows for a class to determine if it is destroyed during a stack unwinding or not. #include <exception> #include <strin...

This code adds outwardly increasing shadows to an image to create a "sticker" version of the image. Notes: In addition to being an ImageObject, the "img" argument can also be a Canvas element. This allows you to stickerize your own custom drawings. If you draw text on the Can...

Once shadowing is turned on, every new drawing to the canvas will be shadowed. Turn off further shadowing by setting context.shadowColor to a transparent color. // start shadowing context.shadowColor='black'; ... render some shadowed drawings ... // turn off shadowing. context.shadowColor=...
