Math

• .s - Show the stack
• +, -, *, mod - Math operators
• /mod - performs both / and mod

Stack manipulation

• drop and 2drop - drop a stack item (once / twice)
• dup - duplicate a stack item
• rot - rotate the stack

; 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.

;; Would like to hear how it works on larger projects.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
