Common Lisp Cheatsheet

Common Lisp is a general-purpose programming language with functions as first-class citizens. Don't worry about being purely functional, Lisp is Object Oriented too. CLOS is a very powerful object-oriented system!

Useful definitions

The Common Lisp lingo is quite unique:

Package: Basically a namespace, a place for symbols to live
System: Basically a Library. A bunch of code plus some instructions how it should be treated, for example which other systems it depends on, what should be loaded and/or compiled first, etc. Not in ANSI lisp but widespread. The most common system definition tool is ASDF.
Modules: Deprecated and implementation-dependent
Quicklisp: Like NPM or Ruby Gems for ASDF Systems.

Awesome Steam Deck

Here I'm gathering awesome things to do with Steam Deck.

	The following assume that you are in the homedir of your private CA userdir (/home/myca). I would suggest creating a limited system account used solely for key creation and signing. Use homedir encryption to protect your CA keys from root compromise.

	Create CA Certificate
	openssl genrsa -des3 -out private/cacert.key 4096 -config conf/caconfig.cnf
	openssl req -new -x509 -days 365 -key private/cacert.key -out certs/cacert.crt -config conf/caconfig.cnf

	Create Server Certificate
	openssl genrsa -des3 -out private/nullbacon.patrick-morgan.net.key 4096 -config conf/caconfig.cnf
	openssl req -new -key private/nullbacon.patrick-morgan.net.key -out nullbacon.patrick-morgan.net.csr -config conf/caconfig.cnf
