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.

Add an empty line after closing ``` and it will work.

comment How do I put YAML code in GitHub MarkDown?
I just tried it, it works fine for me (in preview, did not actually save). Shows on three lines, plain black with only three backticks, syntax-highlighted with ```yaml. No trailing spaces.

comment algorithm to print the digits in the correct order
The problem with this solution is to properly cover edge cases. Logarithm is floating-point number (which are tricky themselves), not to mention, 10-based logarithm is not natural (natural is e-based one), so some more error can accumulate. Which can leads to situations, where log n will be off by one. So you should not blindly believe it, but test the edge case. Also, if you know you have an integer, it is safer (again, floating point, unsafe edge cases) to do things like (1234 - 1234 % (10 ^ [4-1])/(10 ^ [4-1])) to eschew the floating point.

comment How can I explain object-oriented programming to someone who's only coded in Fortran 77?
OOP is (sort-of) simple, C++ "OOP" is not. Take Smalltalk (object has instance variables and a class, class has methods, you send message to and object which is serviced by a method, that's basically it). Prototype-oriented OOP can even put classes off the equation. --- That's why I would recommend (if possible) to only use subset (no private, no protected, no const, no multiple inheritance, all methods virtual, all destructors virtual etc.) so the model is simpler. Add other things later.

@martiert: It is a wrong test. You do not test anything in that test (existence of class is implementation detail).

@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.
