The Hitchhiker's Guide To The Shelley - Chapter 3 - The Staking

This guide's chapter targets the pool operators for getting their head around of Shelley staking. To fully understand the staking mechanism we need to define and interpret the following key concepts:

What are the keys
What are the addresses
What are the certificates and
Who are the stake holders that are participanting in staking.

Keys, Addresses and Certifications

Configure Git to use the osxkeychain

By default, git credentials are not cached so you need to tell Git if you want to avoid having to provide them each time Github requires you to authenticate. On Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account.

You can tell Git you want to store credentials in the osxkeychain by running the following:-

Installing Postgres via Brew

Pre-Reqs

Brew Package Manager

In your command-line run the following commands:

brew doctor
brew update

With this wiki2html.sh bash script and pandoc program, you can convert markdown to html.

Usage: In the vim list section of the .vimrcfile, include options:

let g:vimwiki_list = [{'path': ‘your_wiki_place',
  \ 'path_html': ‘wiki_html_location’,
  \ 'syntax': 'markdown',
 \ 'ext': '.md',

This gist has been moved to its own Github repo, so it's easier to contribute with additions and corrections. Please open a PR there if you see any mistake, I don't track comments on here as there's no notification system for gists AFAIK. Thanks.

Open all files with git merge conflicts in MacVim

git diff --name-only | uniq | xargs mvim

When git encounters a merge conflict, e.g. during a rebase, it drops you back into the shell with a dirty working directory. I like this one-liner for opening all files with a merge conflict in MacVim.

Once you're in Vim, you can then switch between the files with :n and :prev, or another favourite: :w | n (save current file and open the next command line-supplied file).

UPDATE: see below for a version that works with real terminal commands.

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
