Mozilla Developer Central has long been a go to source for for technical documentation of web-standards based development. Now this excellent resource for info on HTML, CSS, JavaScript and the DOM has been organized with a nice clean UI.

Use the new and shiny responsibly.
Look up HTML5, CSS3, etc features, know if they are ready for use, and if so find out how you should use them – with polyfills, fallbacks or as they are

When Can I Use tells you the browser support story, while Modernizr gives you the power of feature detection. HTML5 Please helps you out with recommendations for polyfills and implementation so you can decide if and how to put each of these features to use.

The recommendations below represent the collective knowledge of developers who have been deep in the HTML5 trenches. We hope they serve you well.

Donald Knuth. "Literate Programming (1984)" in Literate Programming. CSLI, 1992, pg. 99.
I believe that the time is ripe for significantly better documentation of programs, and that we can best achieve this by considering programs to be works of literature. Hence, my title: "Literate Programming."

Let us change our traditional attitude to the construction of programs: Instead of imagining that our main task is to instruct a computer what to do, let us concentrate rather on explaining to human beings what we want a computer to do.

The practitioner of literate programming can be regarded as an essayist, whose main concern is with exposition and excellence of style. Such an author, with thesaurus in hand, chooses the names of variables carefully and explains what each variable means. He or she strives for a program that is comprehensible because its concepts have been introduced in an order that is best for human understanding, using a mixture of formal and informal methods that reinforce each other.

Based in part on over 3,000 newsgroup articles written by Python veteran Fredrik Lundh since 1995, this book provides brief descriptions and sample scripts for all standard modules in the Python 2.0 library.

This is a minimal crash-course in the programming language Python. To learn more, take a look at the documentation at the Python web site, www.python.org; especially the tutorial. If you wonder why you should be interested, check out the comparison page where Python is compared to other languages.

This is a short introduction to the art of programming, with examples written in the programming language Python. (If you already know how to program, but want a short intro to Python, you may want to check out my article Instant Python.)

The Filesystem Hierarchy Standard (FHS) defines the main directories and their contents in Linux operating systems. For the most part, it is a formalization and extension of the traditional BSD filesystem hierarchy.

In computer science, a type system may be defined as "a tractable syntactic framework for classifying phrases according to the kinds of values they compute".[1] A type system associates types with each computed value. By examining the flow of these values, a type system attempts to prove that no type errors can occur. T

This is the Git reference site. This is meant to be a quick reference for learning and remembering the most important and commonly used Git commands. The commands are organized into sections of the type of operation you may be trying to do, and will present the common options and commands needed to accomplish these common tasks.

Abstract

Quick introduction to git internals for people who are not scared by words like Directed Acyclic Graph.

"you can only really use Git if you understand how Git works. Merely memorizing which commands you should run at what times will work in the short run, but it’s only a matter of time before you get stuck or, worse, break something.'

"This tutorial, then, will take a conceptual approach to Git. My goal will be, first and foremost, to explain the Git universe and its objectives, and secondarily to illustrate how to use Git commands to manipulate that universe."

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is based on a subset of the JavaScript Programming Language. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages. These properties make JSON an ideal data-interchange language.
