At work we're mostly an OSS shop.  Partly because I have a strong bias towards OSS but cost, reliability, security, etc are all leading factors.  For the last several months now I've been in an interesting position to prove the benefits of OSS in a real-world environment.  We've had to extend a number of OSS tools to fit into our production environment.  These are significant additions and non-trivial.  Open Source allows you to STAND on the shoulders of gods.  For example we've been having a problem with the Jakarta DBCP  connection pool.  It was running out of connections in highly threaded environments and is slow.

Cal Evans has posted a tutorial on the Zend Developer Zone (posted today) about using the PEAR Structures_DataGrid package to create quick and easy data tables.   In this article, I'll be introducing you to the Structures_DataGrid package, showing you how it can be used to display structured data in tabular form. I'll be showing you how to hook it up to various data sources (including a CSV file, an RSS feed and an Excel spreadsheet), and how to format the resulting output so it's as pretty (or as ugly) as you want it to be.   They talk about what you'll need to get started (the different packages for different kinds of data) and some sample code to help you down the path to more attractive tables. There's even a bit touching on some of the more advanced features like exporting to Excel, pagination and data sorting.
