Earth Notes: On Website Technicals

Read my nitty-gritty tech updates and daily learnings while keeping the Earth Notes site up and running; site stats also.

These notes will be updated intermittently, usually when I should be doing something else!

These notes are all about the interesting (and mundane) behind-the-scenes tech bits and bobs to grow and optimise this site, including purely technical measures such as speed, but also user experience beyond just adding new articles and updating existing ones.

Please try the useful tools, reasonably recently used and re-used by me, and encountered while writing these entries, listed under Sources and Links.

The Sources and Links section of each of the site notes pages lists interesting and/or useful resources encountered, even if not directly used for the site.

Also please take a look at the simple automatically-updated site stats below.

I welcome feedback on any of the issues that I have discussed. I share this stuff because it's interesting and because writing it here may save someone else some unnecessary head-scratching! No longer do we need to really know anything technical, nor own a shelf full of reference books (so '90s!), we just need to be able to compose queries for our favourite search engines!

The newest pages are at the top of this list, and the newest items are at the top of each linked page. Enjoy!
