HTML5 introduces many cutting-edge features that enable developers to create apps and websites with the functionality, speed, performance, and experience of desktop applications. But unlike desktop applications, apps built on the web platform can reach a much broader audience using a wider array of devices. HTML5 accelerates the pace of your innovation and enables you to seamlessly roll out your latest work to all your users simultaneously.

The Python Module of the Week series, or PyMOTW, is a tour of the Python standard library through short examples. This is version 1.132, last updated Jul 08, 2011 to cover the ConfigParser module.

Read the Docs hosts documentation for the open source community. It supports Sphinx docs written with reStructuredText, and can pull from your Subversion, Bazaar, Git, and Mercurial repositories. The code is open source, and available on github.

The documentation for the site is organized into two different sections below. One is for users of readthedocs.org, that is the first section. The next section is for users of the code that powers the site. All of the RTD code is open source, so you can run your own instance. Presumably in an internal install inside your company, or something.

Read the Docs hosts documentation, making it fully searchable and easy to find. You can import your docs using any major version control system, including Mercurial, Git, Subversion, and Bazaar. We support webhooks so your docs get built when you commit code. There's also support for versioning so you can build docs from tags and branches of your code in your repository. A full list of features is available.

It's free and simple. Read the Getting Started guide to get going!

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.

In my pursuit to understand Git, it’s been helpful for me to understand it from the bottom up — rather than look at it only in terms of its high-level commands.

Doxygen is a documentation system for C++, C, Java, Objective-C, Python, IDL (Corba and Microsoft flavors), Fortran, VHDL, PHP, C#, and to some extent D.

YARD is a documentation generation tool for the Ruby programming language. It enables the user to generate consistent, usable documentation that can be? exported to a number of formats very easily, and also supports extending for custom Ruby constructs such as custom class level definitions.

The ruby-doc.org Ruby documentation project is an effort by the Ruby community to provide complete and accurate documentation for the Ruby programming language.

Defines descriptors, summarizes the protocol, and shows how descriptors are called. Examines a custom descriptor and several built-in python descriptors including functions, properties, static methods, and class methods. Shows how each works by giving a pure Python equivalent and a sample application.

Docutils is a system for processing plaintext documentation into useful formats, such as HTML, XML, and LaTeX. It supports multiple types of input, such as standalone files (implemented), inline documentation from Python modules and packages (under development), PEPs (Python Enhancement Proposals) (implemented), and others as discovered.

Welcome to the OsiriX Technical Guides. Theses Guides are documented by the OsiriX development Team.

Docutils is an open-source text processing system for processing plaintext documentation into useful formats, such as HTML or LaTeX. It includes reStructuredText, the easy to read, easy to use, what-you-see-is-what-you-get plaintext markup language.

reStructuredText is an easy-to-read, what-you-see-is-what-you-get plaintext markup syntax and parser system. It is useful for in-line program documentation (such as Python docstrings), for quickly creating simple web pages, and for standalone documents. reStructuredText is designed for extensibility for specific application domains.

The primary goal of reStructuredText is to define and implement a markup syntax for use in Python docstrings and other documentation domains, that is readable and simple, yet powerful enough for non-trivial use.

Introspection reveals useful information about your program's objects. Python, a dynamic, object-oriented programming language, provides tremendous introspection support. This article showcases many of its capabilities, from the most basic forms of help to the more advanced forms of inquisition.

I can take your communications project from the concept stage through planning, writing and design, and final publication or production. I can also help plan, prototype, and design Web sites and Web-based applications.

FLOSS Manuals is a collection of manuals about free and open source software together with the tools used to create them and the community that uses those tools. They include authors, editors, artists, software developers, activists, and many others. There are manuals that explain how to install and use a range of free and open source softwares, about how to do things (like design) with open source software, and manuals about free culture services that use or support free software and formats.

Welcome to the Git Community Book. This book has been built by dozens of people in the Git community, and is meant to help you learn how to use Git as quickly and easily as possible.

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.

Analyzing your memory usage is one way to fix other performance problems you may have, such as an increased code footprint or slow code. Efficient memory usage is critical to performance in any application. Increased memory usage not only increases the in-memory footprint of your application, it also increases the time spent allocating and manipulating that memory.
