End of Life and GDPR

If you're reading the community site these days, you certainly noticed that not a single piece of significant content was created since 2015, and not much since 2013.

Whatever this may mean for PHP-GTK itself is another issue, but for the site itself, it means it ceased to be relevant about 5 years ago, and it's time to move on for the site members. Since the site contains non-anonymous user, it will fall under the new EU GDPR regulations entering into force on 2018-05-25, and there is no point for me to spend time on evolving the site towards compliance when no one is actually using it.

So here is the EOL announcement: the site will be shutting down on 2018-05-24 and its data will taken offline.

A static version of the articles may be published again at some point here or elsewhere, but I wouldn't hold my breath on it. So if you have even some interest in the site content, be sure to copy/paste the pages of interest before it goes dark on 2018-05-24. Or contact me if you want a copy of the files and content, or check my blog for newer content.

Thanks all for participating, it's been a pleasure while it lasted.


Random Walk Visualizer

This is about simple random walk (as defined in theory). Uses the cairo library. A ball walks randomly on the screen and leaves a trace behind.

screenshot for <application name />Defined probability for the next step to walk is 0.5. Probabilities for left step and other parameters are pre-defined however someone can change them from inside the constructor at will. Accepted probabilities are from 0 to 1, also -1 is accepted, this indicates that the program choses on its own the probability for the next step to walk. The purpose of this is to show the the usage of cairo library!

The one direction use red color, the other blue color, and black color is used when the walk comes at the starting position. Predifined is 1000 steps and speed 400ms, after this a summary of the steps like a graph is shown on the screen. Other information are displayed on the screen like total count of steps, the current height (how far away is from the starting height), maximum, minimum height, statistical probability from walk history etc.
