For MacOS Catalina, visit Install mysql2 on MacOS Catalina

Problem

Installing mysql2 gem errors on MacOS Mojave.

Solution

Make sure openssl is installed on Mac via Homebrew.

Here we use Homebrew to install rbenv:

brew update; and brew install rbenv ruby-build
Add ~/.rbenv/shims to your PATH
Include the contents of completions/rbenv.fish in your Fish config.
Run rbenv install 2.2.2 and rbenv rehash
Run rbenv global 2.2.2

Now you can run gem install bundler and bundle install within your Ruby project.

Building node-serialport for Electron on Windows

These instruction are for Windows, on my Linux installation(Fedora 21) everything works by just installing serialport with npm (I don't know why!).

These are the steps I did to build node serialport for electron (formerly atom-shell) for Windows. I am completely certain there is a better way to do it, but since I struggled with it for quite a while, here is a solution anyway.

You need some version of Visual studio installed, I have VS 2012 Express for Desktop.

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs
