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.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Nginx behind Apache

Install mod_proxy_http:

a2enmod proxy_http

Add to /etc/apache2/apache2.conf (change ip):

<VirtualHost 11.1.11.111:80 >
	ServerName site.com

Lesson's learnt building the Guardian

Below is a collection of my favourite responses I gathered from Guardian engineers when asked the question: What have you learnt starting from scratch and building a mobile-first next generation web platform for the Guardian?

Work with great people.
Deploy like crazy. This means the team has to control the infrastructure as well as code.
Design is not a service. Designers have to sit in the team.
Infrastructure is intrinsically unreliable. Discard and replace is the robust strategy.
Use your CDN for HTML too.
Don't always do as you are told.
