Git for Beginners (and DropBox Users) I first began using Git because Github was where all the cool kids hung out.
They posted all their cool code and snippets and projects online and had dozens of followers. Yet the only people who could see my super awesome projects that printed “Hello World” were me and the Chrome incognito man. He has seen my code, among other things. So I looked into Github a bit more and realized that Github is actually a resource for users of Git, an easy-to-learn-and-use SCM tool (software configuration management–basically, Dropbox for your software) that works from your command line (though there are also GUIs available, we’re pretty cool cats and prefer the command line–it’s simple and unambiguous).

R is more than a programming language. This document is a work in progress. Assignment and underscore The assignment operator in R is <- as in e <- m*c^2. It is also possible, though uncommon, to reverse the arrow and put the receiving variable on the right, as in m*c^2 -> e. It is sometimes possible to use = for assignment, though I don't understand when this is and is not allowed. However, when supplying default function arguments or calling functions with named arguments, you must use the = operator and cannot use the arrow. At some time in the past R, or its ancestor S, used underscore as assignment. Vectors Sequences. A few things to remember while coding in Python. 30 free programming eBooks - citizen428.blog() Since this post got quite popular I decided to incorporate some of the excellent suggestions posted in the comments, so this list now has more than 50 books in it.
BTW: I’m not very strict on the definition of “ebook”, some of them are really just HTML versions of books. [UPDATED: 2012-01-18] Learning a new programming language always is fun and there are many great books legally available for free online. Here’s a selection of 30 of them: Lisp/Scheme:Common Lisp: A Gentle Introduction to Symbolic ComputationHow to Design ProgramsInterpreting Lisp (PDF, suggested by Gary Knott)Let Over LambdaOn LispPractical Common LispProgramming in Emacs LispProgramming Languages.
Terminology, Syntax, & Introduction - A Beginners Guide to HTML & CSS. Before beginning our journey to learn HTML and CSS it is important to understand the differences between the two languages, their syntax, and some common terminology.
As an overview, HTML is a hyper text markup language created to give content structure and meaning. CSS, also known as cascading style sheets, is a presentation language created to give content style and appearance. To put this into laymen terms, HTML determines the structure and meaning of content on a web page while CSS determines the style and appearance of this content. The two languages are independent of one another. CSS should not reside within an HTML document and vice versa. Instant Documentation Search. Git Immersion - Brought to you by EdgeCase. Greenfoot.

It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, and may be freely distributed. CodingBat.

Git is a version control system (VCS) created by Linus Torvalds, the creator of the Linux kernel. Git is known as a 'distributed” VCS, or DVCS. This means that each user's copy of the code is a fully working repository and includes all previous commit information.
Rather than connecting to a remote server as you would with Subversion or CVS, users can work productively offline, choosing to later sync their changes with a remote repository or create a patch file. Other resources The website for the git project contains a quickstart guide and links to other useful resources. The purpose of this mission is to teach you how to clone a remote repository, make changes to a file, check them into your local copy, and finally create a patch file. Preparing for the mission: Install git If you run Debian, Ubuntu, Fedora, and other systems with a package manager, just search for "git" or "git-core" and install it. Preparing for the mission: Configure git First, tell git your name. Now, show us.
