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.
