All things aside, I believe that these two pieces of code function differently. The first is predecrement, the second is post.
I would agree that for loops make this specific application more obfuscated (not by much, but it is certainly less clear). I recommend using for loops primarily for iter...
I've been running through The Little Schemer, and have hit the example of Peano multiplication. The solution is given in TLS (reproduced below) -- however what interests me is the order of the algorithm.

Those of you that weren't following what's going on in the chat room might have been taken by surprise by a recent avalanche of Rock Paper Scissors Lizard Spock posts.

I was hoping to see a Math/Logic Puzzle of some sort.
Towers of Hanoi: Towers Of Hanoi is fairly simple and there are many solutions out there. But it seems we all have our own way of solving it.
Conway's Game of Life: aka Life is much more complex and might take too long ...
The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970.
The "game" is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves.
Rules
The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, alive or dead. Every cell interacts with its eight neighbours, which are the c...

First CodeGolf post, so I figured that I would have fun with it.

This is yet another follow-up of Poker Hand Evaluation from the last weekend-challenge. This method works for both 5 and 7 card hands - it doesn't fill the gaps with jokers, but I'm happy with the passing tests:

I just stumbled upon something today that seemed "unethical" in PHP. What originally thought as malpractice, turns out to work just fine. Basically what I was wondering if pushing an instantiated class in an array was considered proper?
Example:

Thanks for taking the time to read this.

The problem lies most in the add_helper function, and I still can't figure out how to debug and fix the error. Thank you.

I have a pretty simple problem. A large set of unique strings that are to various degrees not clean, and in reality they in fact represent the same underlying reality. They are not person names, but they could be. So for example Dr. John Holmes and Dr. Jon Holms are more than likely the same pers...

I have a desktop application writing in java and using mysql as a database, now i need to embed hsqldb instead of mysql, how can i go about that using hibernate.
when I execute the following code
CREATE TEMPORARY TABLE IF NOT EXISTS ETL.TempReallocation AS (

reallocation.offices_realloue_id AS offices_alloue_id ,
reallocation.offices_id AS offices_id ,
reallocation.specialism_id AS specialism_id ,
reallocation.businessline_id AS...
That code looks pretty complex for the trivial task it does.
No need to convert the string to a char array. By not calling ToCharArray() you get rid of an extra copy of data.
Poorly named variables IMHO. (The convention for index is i.)
No need to substract from the end index. (which I prefer t...

The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare.
In this context, "almost surely" is a mathematical term with a precise meaning, and the "monkey" is not an actual monkey, but a metaphor for an abstract device that produces an endless random sequence of letters and symbols. One of the first instances of the monkey metaphor being used comes from French mathematician Émile Borel in 1913 but it may go back further than that....
