Vim has a Terminal Mode!

Since v8.1 (May 2018), Vim has shipped with a built-in terminal. See https://vimhelp.org/terminal.txt.html or type :help terminal for more info.

Why use this? Mainly because it saves you jumping to a separate terminal window. You can also use Vim commands to manipulate a shell session and easily transfer clipboard content between the terminal and files you're working on.

Key Bindings

Arch + i3-gaps Install Guide

First set up your keyboard layout. For example, in Spanish:

   # loadkeys es

For a list of all acceptable keymaps:

   # localectl list-keymaps

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
Microsoft Windows 7 SP1 as the host OS
A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

Install Multiple Java Versions on macOS High Sierra

Install Homebrew Cask

On Mac, Homebrew is the de-facto package manager, and Homebrew Cask is the app manager. I’m going to use Cask to install Java 7 and 8.

Install Homebrew Cask first if you haven’t:

brew update
brew tap caskroom/cask

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

1.) Download a Nerd Font

2.) Unzip and copy to ~/.fonts

3.) Run the command fc-cache -fv to manually rebuild the font cache

This is a well known issue, and it has a solution that is confirmed to work for the Mac side.

sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid

After you run this script, the issue will go away and BT connections will remain stable.
