A great regular expression cheat sheet

This is a really good cheat sheet for regular expressions.

How many times have to sat there and wondered what a reg ex for a specific function would be and then had to search for it on google?

Well, if that has happened to you, simply download and print this cheat sheet.

SVN - Subversion Cheat Sheet

This is a subversion cheat sheet.

What is Subversion (also known as SVN)?

This is from the Subversion website (http://subversion.tigris.org/)

The goal of the Subversion project is to build a version control system that is a compelling replacement for CVS in the open source community. The software is released under an Apache/BSD-style open source license.

• Most current CVS features.

  Subversion is meant to be a better CVS, so it has most of CVS's features. Generally, Subversion's interface to a particular feature is similar to CVS's, except where there's a compelling reason to do otherwise.

• Directories, renames, and file meta-data are versioned.

  Lack of these features is one of the most common complaints against CVS. Subversion versions not only file contents and file existence, but also directories, copies, and renames. It also allows arbitrary metadata ("properties") to be versioned along with any file or directory, and provides a mechanism for versioning the `execute' permission flag on files.

• Commits are truly atomic.

  No part of a commit takes effect until the entire commit has succeeded. Revision numbers are per-commit, not per-file; log messages are attached to the revision, not stored redundantly as in CVS.

• Apache network server option, with WebDAV/DeltaV protocol.

  Subversion can use the HTTP-based WebDAV/DeltaV protocol for network communications, and the Apache web server to provide repository-side network service. This gives Subversion an advantage over CVS in interoperability, and provides various key features for free: authentication, path-based authorization, wire compression, and basic repository browsing.

• Standalone server option.

  Subversion also offers a standalone server option using a custom protocol (not everyone wants to run Apache 2.x). The standalone server can run as an inetd service, or in daemon mode, and offers basic authentication and authorization. It can also be tunnelled over ssh.

• Branching and tagging are cheap (constant time) operations

  There is no reason for these operations to be expensive, so they aren't.

  Branches and tags are both implemented in terms of an underlying "copy" operation. A copy takes up a small, constant amount of space. Any copy is a tag; and if you start committing on a copy, then it's a branch as well. (This does away with CVS's "branch-point tagging", by removing the distinction that made branch-point tags necessary in the first place.)

• Natively client/server, layered library design

  Subversion is designed to be client/server from the beginning; thus avoiding some of the maintenance problems which have plagued CVS. The code is structured as a set of modules with well-defined interfaces, designed to be called by other applications.

• Client/server protocol sends diffs in both directions

  The network protocol uses bandwidth efficiently by transmitting diffs in both directions whenever possible (CVS sends diffs from server to client, but not client to server).

• Costs are proportional to change size, not data size

  In general, the time required for a Subversion operation is proportional to the size of the changes resulting from that operation, not to the absolute size of the project in which the changes are taking place. This is a property of the Subversion repository model.

• Choice of database or plain-file repository implementations

  Repositories can be created with either an embedded database back-end (BerkeleyDB) or with normal flat-file back-end, which uses a custom format.

• Versioning of symbolic links

  Unix users can place symbolic links under version control. The links are recreated in Unix working copies, but not in win32 working copies.

• Efficient handling of binary files

  Subversion is equally efficient on binary as on text files, because it uses a binary diffing algorithm to transmit and store successive revisions.

• Parseable output

  All output of the Subversion command-line client is carefully designed to be both human readable and automatically parseable; scriptability is a high priority.

• Localized messages

  Subversion uses gettext() to display translated error, informational, and help messages, based on current locale settings.

Finally here is the cheat sheet.

First cheat sheet - CSS (Cascading Style Sheets)

This is the first cheat sheet I am posting.

It is for CSS : Cascading Style Sheets.

What is CSS?

• CSS stands for Cascading Style Sheets
• Styles define how to display HTML elements
• Styles are normally stored in Style Sheets
• Styles were added to HTML 4.0 to solve a problem
• External Style Sheets can save you a lot of work
• External Style Sheets are stored in CSS files
• Multiple style definitions will cascade into one

Welcome to the best cheat sheets on the web

I have been trying to collect and create my own cheat sheets for a long time and I decided one day to share what I have with all of you.

A cheat sheet is something extremely valuable for people from all walks of life, be they IT professionals, students, lawyers or really anybody as long as they can find the cheat sheet they desire. Since most cheat sheets are used in the world of computing, this site will have more computer related cheat sheets but will definitely have a lot of general cheat sheets as well.

I will begin posting the cheat sheets shortly.

If you have something specific in mind that you would like to see on this site, please add a comment and I will try to accomodate you.

Thank You!!
