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.

Looking at the most beautiful program ever written - part 1

I am going to have a look at what William Byrd presented as The most beautiful program ever written.

Beauty here refers to computer programs, specifically about Lisp. There might be errors as this is something I wrote to make sense of that interpreter, proceed at your own risk.

Thanks a lot to Carl J. Factora for the help.

This document has moved!

It's now here, in The Programmer's Compendium. The content is the same as before, but being part of the compendium means that it's actively maintained.

Post Strange Loop BBQ Tour

Like [last year][1] I am planning to visit many of the BBQ joints in Saint Louis, most of which are not in walking distance of the conference venues. Unlike in 2015, the [Q in the Lou BBQ][6] festival will not conveniently overlap dates with the Strange Loop conference- Q in the Lou will occur the weekend following Strange Loop.

Itinerary

This is the itinerary. We will leave Union Station in groups using UberXLs or cabs around 10:30 am. Meet outside the main doors at Union Station Double Tree on Market Street.
