Packt publishing has offered me to make a review of two of their new books (Thanks to them). I should receive free samples for review beginning of next week. Since it is two of my favorite subjects (Maven and Joomla!® ), I think it may also interest you. A review will follow in some days.
- Make your extensions extensible, add extensions points to allow third parties to customize your extension
- Create international extensions by enabling multilingual capabilities
- Build more than just HTML pages - create PDF documents, Atom Feeds, and more!
- Improve the user experience by adding Ajax
- Create Atom and RSS feeds to keep users up-to-date
- Utilize the power of Subversion to maintain your source code
- Execute database queries and handle returned data in order to access and modify your data
- Dynamically extend your database tables using JParameter to make your extensions more flexible
- Keep your gremlins at bay by handling errors the Joomla! way
- Work with the file system, interrogate existing files and folders and store data in the file system
- Take control of your workflows by using www.JoomlaCode.org to manage your Joomla! projects
Ehcache is an open source, standards-based cache used to boost performance, offload the database and simplify scalability. Ehcache is robust, proven and full-featured and this has made it the most widely-used Java-based cache. It can scale from in-process with one or more nodes through to a mixed in-process/out-of-process configuration with terabyte-sized caches. For applications needing a coherent distributed cache, Ehcache uses the open source Terracotta Sever Array.
|At SD Forum 2006, Randy Shoup and Dan Pritchett, both with eBay, gave a presentation on eBay's architecture. Pritchett subsequently posted his presentation slides in his blog, The eBay Architecture.
Predictably, the presentation contained a few inspiring statistics, such as:
Other stats in the presentation related to development process and features, such as:
restart Apache and you can continue debugging!
Here is 3 different way to control the lifetime a local Tomcat 7 container using Apache Maven. A typical scenario would be to start a servlet container prior to running integration tests (Selenium, SAHI or using any other framework you can think of )
With the following examples, you will be able to start an instance of Tomcat 7 running your web application in the pre-integration-test phase and stop the instance in the post-integration-test phase. You can also decide to use an embedded container like Jetty instead.
The Apache POI Project's mission is to create and maintain Java APIs for manipulating various file formats based upon the Office Open XML standards (OOXML) and Microsoft's OLE 2 Compound Document format (OLE2). In short, you can read and write MS Excel files using Java. In addition, you can read and write MS Word and MS PowerPoint files using Java. Apache POI is your Java Excel solution (for Excel 97-2008). We have a complete API for porting other OOXML and OLE2 formats and welcome others to participate.
From the documentation at http://poi.apache.org/utils/logging.html
Logging in POI is used only as a debugging mechanism, not a normal runtime logging system. Logging is ONLY for autopsie type debugging, and should NEVER be enabled on a production system. Enabling logging will reduce performance by at least a factor of 100. If you are not developing POI or trying to debug why POI isn't reading a file correctly, then DO NOT enable logging. You've been warned.
In order to effectively disable the logging functionality in Apache POI you must use an alternative logger. This is accomplished by providing a property to the
POILogFactory to override the default logger. You can add one of these –D to your JVM settings
I found Apache POI to slightly better perform with the NoOpLog of apache common!
You can create a custom build of Apache POI 3.8 and alter the following properties to better match the size of the excel files you are generating or reading:
This will only work if you do not reach xls limitations which may avoid you to go to that extreme solution. XLS is not compressed (XLSX is xml based and compressed) and your workbook may double size in memory as a result!
For example, data beyond 256 (IV) columns by 65,536 rows will not be saved in xls! In Excel 2010 and Excel 2007, the worksheet size is 16,384 columns by 1,048,576 rows, but the worksheet size of Excel 97-2003 is only 256 columns by 65,536 rows. Data in cells outside of this column and row limit is lost in Excel 97-2003. But there is a lot more limitations listed at office.com…
The biggest side effect was that my excel file went from 354kb to 967kb, but the speed increase was quite interesting: more than 44% less evaluation time.
I don’t think these bring a lot of speed, JIT should optimize this bad piece of code for us but it is always worth trying Speeding up org.apache.poi.hssf.usermodel.HSSFRow.compareTo() and http://affy.blogspot.ch/2004/04/poi-optimization-speeding-_108265938673224937.html

A free open source Java virtual machine and classes librairies!!!
Purpose of this project is to create and use an open source, compatible implementation of J2SE
5, the latest version of the Java 2 Standard Edition specification.
"The Apache Software Foundation provides support for the Apache community of open-source software projects. The Apache projects are characterized by a collaborative, consensus based development process, an open and pragmatic software license, and a desire to create high quality software that leads the way in its field. We consider ourselves not simply a group of projects sharing a server, but rather a community of developers and users."
