Variant Whitespace is a nice minimalistic template by Andreas Viklund.
Andreas chose to put the sidebar above the content, which I prefer not to do. Furthermore as the sidebar was a “float” that came before the content, it caused additional inconveniences. E.g. if you had an element with

Passing around timestamps in URLs is a common task. We usually want our URLs to be as shortest as possible. I’ve found using Base64 to result in the shortest URL-safe representation, just 6 chars. This compares with the 12 chars of the naive way, and 8 chars when using hex representation.
The following Python functions allow you to build and read these 6 chars URL-safe timestamps:

Every good web programmer will note that the following contact form markup is probably flawed
<input type="hidden" name="to" value="firstname.lastname@example.org" />
as it is likely that if the value of the “to” field changes the message will be sent to the modified address. The problem with this kind of functionality is that it allows a malicious user to send emails from your mail server.

As this case is pretty obvious one doesn’t see many real-life uses of it anymore (but careless programmers used it more often n the past until they learned better). However one can achieve similar goals (spam-wise) by utilizing a common feature in contact forms: the “CC yourself” checkbox.
