Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

LUA Record Type for Lua-powered DNS records for standards based fail-over and geographical load balancing

Recently, many zone owners could not migrate away from Dyn since they were benefiting from non-standardised DNS-based failover and geographical loadbalancing features. What you see below is an attempt to get standards based but flexible equivalents of these currently proprietary features. Here is a zone:

The BBC has a server-side image service which provides developers with multiple sized versions of any image they request. It works in a similar fashion to http://placehold.it/ but it also handles the image ratios returned (where as placehold.it doesn't).

The original BBC News process (and my re-working of the script) follows roughly these steps...

Create new instance of ImageEnhancer
Change any divs within the page (which have a class of delayed-image-load) into a transparent GIF using a Base64 encoded string.
- We set the width & height HTML attributes of the image to the required size
- We know what size the image needs to be because each div has custom data-attr set server-side to the size of the image
- We then set a class of image-replace onto each newly created transparent image
We use a 250ms setTimeout to unblock the UI thread and which calls a function resizeImages which enhances the image-replace images so their source is now set to a URL whe
