I wrote a scanner/lexer to parse my language. Some notes:
I'm scanning files written in UTF-8.
I avoided regex for two reasons:
It feels far easier to simply handle codepoints one at a time than to get regex to handle Unicode properly.

Hello Code Review family,
I create a little PHP script and I want to improve it !

There's my code :

The infinite monkey theorem states that, given infinite time, a machine sending an endless stream of random characters will always type any given text.
That sounds to me like a great idea for a challenge.

Well, I'm back again! But this time with a more advanced, slightly more completed program for my Blackjack project. It's come quite a way since I first posted about it, and I'd like to thank those who offered their help and suggestions to improvements to the program!

I programmed a class for database access for my REST service. According to my understanding it should be implemented as singleton, because there can be a lot of simultaneous requests. Is there everything okay with this approach?

Inspired by this question on CodeReview, and because I'm never able to beat the queue.
I'm just too slow I guess.. :(
I made a little python utility that reads the queue's information every 30 seconds and opens the link in your browser if we can review something.

All,
Please excuse my potentially noob-ish question. I haven't touched strings in C (or C in general) in a while, and I seem to recall there being different ways you can return a C string from a function (as discussed here: https://stackoverflow.com/questions/25798977/returning-string-from-c-fu...
