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 Are there any programming languages that follow a minimalist development approach?
"Worse is better" effect, and in case of Smalltalk also some marketing mistakes (it has its heyday in 80s but it was expensive so C took over). Performance was not the main issue (and is definitely not now, when compilers are much smarter, look up Self project if you want more details on this). But Lisp is THE functional language (and its descendant Haskell performs good), and Smalltalk is THE object-oriented language (Pharo is the contemporary professional dialect, and is free, with constantly developing VM).

comment DDD and Value Objects. Are mutable Value Objects a good candidate for Non Aggr. Root Entity?
Is there such thing as "mutable value object"? I always had the impression value objects are immutable.

comment Which is more effective in coding? Reducing line of code and execution of code?
"one of TDD/BDD major goals is to write enough code only to make the test pass" Well, don't confuse tools with goals. Major TDD/BDD goals is good code design. "enough code only to make the test pass" is only a one of the tools to achieve that, but it's only half of the equation, the other side being you incrementally add more tests, until the code does what it should (or, as IIRC Ward Cunningham pointed and Kent Beck included in the book, "until fear transforms into boredom").

comment Is there a way to add unique items to an array without doing a ton of comparisons?
Algorithmically, this is still O(n^2), because of insertions. kevin cline's answer is the only hashless one which gets you to O(n*log n). You can then make an array from the tree after the whole operation and you're done.

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.
