Declare some variables.
* q is the light's current location.
* G is the game board as a 1D array.
* p is the current read location when populating G.
* w is the board's width.

Obvious main. m is a variable storing the movement vector. (It's a parameter to main as an optimization.)...
SHA1 vs md5 vs SHA256: which to use for a PHP login?
... different sites—otherwise a simple delay after input would do. And the "game over if they got in your server" is a moot point, because they don't need to get inside your server. The most common vulnerability hackers use has been SQL injection (see the Linkedin case), then they bruteforce the hash...
What is the best way to compare floats for almost-equality in Python?
...ample, perhaps we are going to calculate where a ball thrown in a computer game traveled, and we want to know whether it struck a bat. In this case, we certainly want to get "true" if the ball strikes the bat, and we want to get "false" if the ball is far from the bat, and we can accept an incorrect...
What platforms have something other than 8-bit char?
...uttons -- whose purpose, ironically, was to slow the computer down so that games using the time-delay technique could be played at a reasonable speed.
One commenter asked where in the standard it says that char must have at least 8 bits. It's in section 5.2.4.2.1. This section defines CHAR_BIT, t...
Two-way encryption: I need to store passwords that can be retrieved
...viously, if the encrypted password and the encryption key are stolen, then game over.
I'd put a rider on my answer - I'm not a PHP crypto expert, but, I think what I have answered is standard practice - I welcome comments other may have.

How do you detect where two line segments intersect? [closed]
...int. It is based on an algorithm in Andre LeMothe's "Tricks of the Windows Game Programming Gurus". It's not dissimilar to some of the algorithm's in other answers (e.g. Gareth's). LeMothe then uses Cramer's Rule (don't ask me) to solve the equations themselves.
I can attest that it works in my feeb...
How is TeamViewer so fast?
...re plethora of open source
solutions, and Tight is probably on top of it's game right now.
Advanced VNC implementations use lossy compression and that seems to achieve
better results than your choice of PNG. Also, IIRC the rest of the payload is also
squashed using zlib. Bothj Tight and UltraVNC h...
Design by contract using assertions or exceptions? [closed]
...to transfer $1,000,000 instead of $1,000. But what if you're programming a game? Maybe you need all the speed you can get, and if someone gets 1000 points instead of 10 because of a bug that the preconditions didn't catch (because they're not enabled), tough luck.
In both cases you should ideally h...
Comparison of full text search engine - Lucene, Sphinx, Postgresql, MySQL?
... used to solve real-time problems. For search engines, Solr is pretty much game and works flawlessly.
Solr works fine on High Traffic web-applications (I read somewhere that it is not suited for this, but I am backing up that statement). It utilizes the RAM, not the CPU.
