A heart created with D3 and a nice formula found on Wolfram to celebrate Valentine's Day!

The second example of a heart from one sharp line can be found here

A representation of the current time of year using the Sun, Earth, and Moon.

The position of the Earth in orbit around the Sun indicates the hour of year. The Earth itself is a pie chart indicating the second of day. The Moon's position in orbit around the Earth indicates the hour of month. The time is updated every second.

How to set up stress-free SSL on an OS X development machine

One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.

Most workflows make the following compromises:

Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.
Use production SSL certificates locally. This is annoying
