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.

The command line, in short…

wget -k -K -E -r -l 10 -p -N -F --restrict-file-names=windows -nH http://website.com/

…and the options explained

• -k : convert links to relative
• -K : keep an original versions of files without the conversions made by wget
• -E : rename html files to .html (if they don’t already have an htm(l) extension)
• -r : recursive… of course we want to make a recursive copy
• -l 10 : the maximum level of recursion. if you have a really big website you may need to put a higher number, but 10 levels should be enough.

Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the
