An iTerm2 Cheatsheet

In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So + D does not mean hold shift. + Shift + D does of course.

Tabs and Windows

Function Shortcut
New Tab + T
Close Tab or Window + W (same as many mac apps)
Go to Tab + Number Key (ie: ⌘2 is 2nd tab)
Go to Split Pane by Direction + Option + Arrow Key

About

This is a collection of snippets, not a comprehensive guide. I suggest you start with Operational PGP.

Here is an incomplete list of things that are different from other approaches:

  • I don't use keyservers. Ever.
  • Yes, I use Gmail instead of some bespoke hipster freedom service

IDE Scripting

Here are my attempts to script an IntelliJ-based IDE using javax.script.* API (ex-JSR-223).

The list of available scripting languages and engines:

  1. Groovy - built-in, via Groovy jars and <app>/lib/groovy-jsr223-xxx.jar
  2. JavaScript (Nashorn) - built-in, via Java Runtime <app>/jbr/... (deprecated and will be removed soon)
  3. JavaScript (GraalJS) - https://plugins.jetbrains.com/plugin/12548-intellij-scripting-javascript
  4. JPython - https://plugins.jetbrains.com/plugin/12471-intellij-scripting-python
  5. JRuby - https://plugins.jetbrains.com/plugin/12549-intellij-scripting-ruby
  6. Clojure - https://plugins.jetbrains.com/plugin/12469-intellij-scripting-clojure

Short guide to TCP/IP Client/Server programming in Common Lisp using usockets
; Short guide to TCP/IP Client/Server programming in Common Lisp using usockets
;
; The main reason for this guide is because there are very few examples that
; explain how to get started with socket programming with Common Lisp that I
; could understand. After spending a day trying, I finally came up with a small
; bit of code that makes it easy to understand the basics. I've written this
; primarily for myself, but should help others get started as well.
; As usual, we will use quicklisp to load usocket.

Operational PGP

This is a guide on how to email securely.

There are many guides on how to install and use PGP to encrypt email. This is not one of them. This is a guide on secure communication using email with PGP encryption. If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.
