These pages about different languages / apis / best practices were mostly jotted down quckily and rarely corrected afterwards.
The languages / apis / best practices may have changed over time (e.g. the facebook api being a prime example), so what was documented as a good way to do something at the time might be outdated when you read it (some pages here are over 15 years old).
Just as a reminder.

You can disguise a domain name as a hex-ed domain name, so people dont know where they will end up when they click on it. The real use of this is probably none, but it can be used to fool friends when sending them links :)
