Garbage-collecting duck-typer. Test-infected. Hopefully he is not alone who would like UNIX rewritten with GC memory and closure support in system, kernel API in Javascript, (Python, Ruby, Smalltalk), and C layer deprecated and emulated on top of the former.

I use Windows on workstation and FreeBSD on server.

Recently dipped myself into the mobile app world.

comment Test Driven Development Code Order
@martiert: It is a wrong test. You do not test anything in that test (existence of class is implementation detail).

comment Test Driven Development Code Order
@ollins: Yes. Or, from the bigger PoV, "Never write a line of code without a failing test.", that is, never write any piece of production code which is not necessitated by existence of failing test and which makes this failing test pass. Kent Beck calls this approach "test-infected".

comment Misunderstanding Scope in JavaScript?
Sort of. I said it can't be "passed" because by passing I meant giving it to someone else to manipulate. But it is not passed in that sense, it is just "brought with" the closure - only the code inside the closure can see/manipulate it. But these are the details (the devil is in the details ;-) ). BTW, functions returning functions are pretty common stuff in JavaScript; usage of closures to "simulate private variables" etc. are common patterns which all base upon closures (returned from other functions) having lexical scope.

comment Misunderstanding Scope in JavaScript?
GlenPeterson said it right. apply and call are about setting this for a call; there is no way to pass scopes at all. But you must take into account that functions are in fact lexical closures so they take hold of their scope for their lifetime. The articles aim to show this, that is why I recommended them.

comment Does software testing methodology rely on flawed data?
IIRC, Kent Beck did not say the curve is flat after the first rise, only that it is "almost flat" but still rises slightly.

comment How to write reusable code in node.js
It is not very clear what is your problem, maybe rephrase it. I'd have two comments: 1. Maybe you just need to get used to async/callback way of doing things, I do not see anything like "unmanageable code soup" there. 2. Ad "loosely coupled classes": do you really need "classes" there? Classes are not needed to do OO neither to do good design. Maybe change the title.

comment Is there a difference between multi-tasking and time-sharing?
With multiprocessor / multicore, you can have true multitasking where more programs actually run at the same time in parallel.

comment Why the overhead when allocating objects/arrays in Java?
C also has an overhead, each malloc-allocated block of memory needs a header which free then uses.

comment Is there a programming language where 1/6 behaves the same as 1.0/6.0?
In all Smalltalk-80 derivates (that is, nearly all Smalltalks). Amber is one of contemporary exceptions (which is understandable, being compiled to JavaScript).
