capture is a CGImageRef returned from a call to CGWindowListCreateImage(). When I try to turn it into an NSImage directly it mysteriously doubles in size. If I manually create a an NSBitmapImageRep from capture and then add it to an empty NSImage everything works ok.

My hardware setup is a retina MBP + non-retina external display. The capture is taking place on the non-retina screen.

NSLog(@"capture image size: %d %d", CGImageGetWidth(capture), CGImageGetHeight(capture));
NSLog(@"logical image size: %f %f", viewRect.size.width, viewRect.size.height);

NSBitmapImageRep *debugRep;
NSImage *image;

Scoping in a beginner's language:

a := 10
def foo {
    a := 20
}

foo()
print a -- should this output 10 or 20?

I have a task system that is controlled by a kernel. This is a simplified version of the spawn logic:

var task = new taskCtor();
taskState.state = INIT; // taskState is private to kernel
task.init();
taskState.state = RUNNING;
task.run();
taskSpawned.emit(task.id); // this is a signal that notifies system a task has been spawned
return task.id;

I'm designing a programming language for beginners/kids and am trying to keep the syntax for basic usage as simple as possible, while still providing useful features for more advanced users such as first-class functions and lambda expressions.

In particular I'm keen that it should be possible to call functions without parentheses:

print "hello world"

	#include <stdio.h>
	#include <stdlib.h>
	#include <signal.h>

	typedef enum opcode {
	OP_HALT = 0,
	OP_NOP,
	OP_JMP,
	OP_MAX
	} opcode_t;

	//
	// Lame implementation of a channel

	function channel() {
	return new Channel();
	}

	function Channel() {
	this._queue = [];
	this._waiters = [];

	function makeProgressPromise(cb) {

	var currentProgress = 0;
	var progressListeners = [];

	function updateProgress(newProgress) {
	currentProgress = newProgress;
	progressListeners.forEach(function(listener) {
	try {
	listener(currentProgress);
