Demystifying de-duplication
559680
Compression rates with de-duplication technology range from 3:1 to 500:1 and can reduce backups to the point where disk is a viable online alternative to traditional tape backups.

DevShed has posted the second and last part of a series of two articles based around the Composite design pattern - using it to work with strings in PHP5.   Are you a PHP developer who wants to improve your skills in pattern-based programming in PHP? If the answer to this question is a emphatic yes, then you should begin reading this article now! Welcome to the final part of the series "Implementing the composite pattern with PHP 5." Comprised of two instructive tutorials, this series walks you through the basic concepts of this important design pattern, and shows you how to apply it with some educational examples.   They start by defining a simple StringProcessor class as an abstract interface to build from. From there, they create two other classes - the SingleStringProcessor and the MultipleStringProcessor. Each of these takes in either a single file or multiple filenames and spits back out the value of the string and the length of the string.

DevShed is starting up another new series today, this time looking at the DirectoryIterator methods out of the Standard PHP Library functionality.   Because this class might be handy to use in projects where handling directories is a must, in this new series I'll be taking a close look at some of its most important methods. We will explore these methods appropriately in conjunction with the corresponding code samples.    They introduce the class, noting why it's handy to use and where's the best place to use it - including an example. They get into a bit more detail, looking at the key() and current() methods as well as using the rewind() method to reset the pointer for the directory.

AgileWiki explores new knowledge representation. The current effort is on implementing a copy-on-write OODBMS with support for fast deep copies, b-trees, large extensible hashes, simple lists, bush structures and calendars.   CowDb is a new kind of Object Store based on Copy-On-Write technology. It supports fast deep copies, b-trees and large extensible hashes.   http://agilewiki.wiki.sourceforge.net/CowDb

In his travels as a PHP developer, Jamie Wong has gathered some helpful debugging tips that are shared in this latest post to his blog.   Here are some bugfixing rules and tips Iâve learned working all these years with PHP. I emphasize mostly on fixing bugs than preventing them, which is another subject worth of its own article. Iâve moved to Rails, but I wanted to finish this post as a farewell and thanks to every article and documentation that was useful to me. Hope this is useful to you too.   Topics covered include:  Assume nothing Turn Error Reporting to show all errors Read the error message Understand the bug "Scooby-Bug, where are you?" Get as much information as possible  Each has some explanation below it and, in some places, a bit of code to clarify the point.

DevShed ramps up another new series today with this new article giving developers a look at working with object-oriented programming through the eyes of design patterns. It's another excerpt from the George Schlossnagle book "Advanced PHP Programming".   This chapter provides an overview of the advanced OO features now available in PHP. Some of the examples developed here will be used throughout the rest of this book and will hopefully serve as a demonstration that certain problems really benefit from the OO approach.   The article lays down the foundation for the more complex information to come. It introduces object-oriented programming briefly, and talks about some of the handy features of it - like inheritance, static attributes and methods.
