Rather than copying and pasting code between projects, plugins can be created for easy reuse. A bug found in Website B can be fixed and easily shipped to Website A.
In a multisite install, that plugin can be made available to all subsites. This approach can also be used to install and update proprietary plugins, which have not been published to the plugin directory.

I just checked w/ our Website Builder team regarding your specific question, and here's what they said: "Website Builder automatically creates a site map for all published websites but does not automatically submit it to search engines. For customers who update their website using the SEO wizard (on the Business Plus plan) we also do automatically submit the site map to the search engines on their behalf."
The sitemap is available at http://www.domain.com/sitemap.xml.

MD5 is a secure hash algorithm. It takes a string as input, and produces a 128-bit number, the hash.
MD5 and SHA1 are designed for a number of properties, one of the strongest being collision resistance. This means that it should take an enormous computational effort -- around 264264 MD5 calls or 280280 SHA1 calls -- in order to find two files that have the same hash output.
This is an important property for a number of applications, most obviously digital signatures.

The one or single occasion; the present reason or purpose (now only in for the nonce).
That will do for the nonce, but we'll need a better answer for the long term.

This code causes the Geolocation EXIF to the attachment metadata stored in the database.
It is run when an image is uploaded into WordPress.
I found that by adding a call to 6q3rVgtQsiH0820S_2_read_image_metadata into my dtrt_gallery_thumbnail_link function (hooked into 6q3rVgtQsiH0820S_2_get_attachment_link) resulted in the attachment metadata being added for existing images.
