Signing your Git Commits on MacOS

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.

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

FlowMap: An Optimal Technology Mapping Algorithm for Delay Optimization in Lookup-Table Based FPGA Designs

the classic paper
compute LUT mappings through maximum-flow
produces optimal depth designs
but needs major area recovery, e.g. flow-pack
implemented in the Yosys flowmap pass.

On Area/Depth Trade-off in LUT-based FPGA Technology Mapping

relaxing requirement of one logic gate to one LUT allows area recovery
duplicates logic to produce more LUT mapping opportunities

Widget

A widget is the basic type of controller in Flutter Material. There are two type of basic Widget we can extend our classes: StatefulWidget or StatelessWidget.

Stateful

StatefulWidget are all the widget that interally have a dynamic value that can change during usage. It can receive an input value in the constructor or reference to functions. You need to create two classes like:
