Last active August 29, 2015 14:01
For those who want an Optional but haven't upgraded to Java 8 yet. If you use this, it should be fairly simple to refactor using the "real" Optional in the future.
import java.util.NoSuchElementException;
/**
* My own little implementation of optional. Lacks other Java 8 features such as filter on Predicate,
* eating the value up with a consumer, etc.
* <p>
* One possible benefit: If you try to get() the value, but haven't checked whether it isPresent(),
* this will throw an exception. You must always check if the value is present before getting it.
* <p>

A little snippet to make sure that jQuery is loaded before running code.

Something I threw together to test storage abilities in different browsers.
<!--
Something I threw together to test storage abilities in different browsers.
This test two forms of session storages: html 5 session storages, and the window.name fallback option.
It also tests two forms of persistent storage: html 5 local storage and cookies.
Intended usage:
Upload the html file to your web-server.
