Signing your Git Commits using GPG on MacOS

Methods of Signing with a GPG Key on MacOS

Last updated September 21, 2022

This Gist explains how to do this 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.

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

There has been a number of comments on this gist regarding some issues around the pinentry-program and M1 Macs. I've finally gotten a chance to try things out on an M1 and I've updated the documentation in 2-using-gpg.md to reflect my findings.

How I Got Node.js Talking on EC2's Port 80

The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

One possibly-right way:

Add a port forwarding rule via iptables.

First, I listed the rules currently running on the NAT (Network Address Translation) table:

NGINX tuning for best performance

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
