This is a very simple and easy article, which gives an idea for track the IP address and for getting the number of cliks from a particular system.

The ical4j library is probably the reference java library for manipulating iCalendar data. It offers a full representation of the iCalendar (RFC 2445) data model (calendar components, properties and parameters), a parser, as well a set of helper classes to do date/time calculations.

Another option to serialize objects is using the XML format. It has a lot of advantages, but its not performing well. In come cases this performance aspect is only a very small part of the transaction, but since there is so much of SOAP protocols floating around, in some cases they should be reconsidered. The fastest Java XML library that I know of is StAX. I've created a matching XML to the Thrift and Protobuf schemas, limiting the tag sizes to only two chars. Makes the XML not too readable, but limits its total size. Here are the performance charts comparing to StAX with Java plain Serialization, Thrift and Protobuf.

Demand for multi-core/multi-processor applications is growing, but developing for a multi-threaded application does not require a steep learning curve or an understanding of complicated edge cases. Learn how to develop efficient multi-threaded applications without using synchronized blocks.

I use a simple PowerShell script to replace some of the URLs in my blog post's html source before I publish them to www.tellingmachine.com. In my case the posts are stored as XML files. Usually I use Windows Live Writer to write my posts. I publish the documents for test purposes frequently during the authoring to the VisualStudio 2008 development web server that runs locally on my machine. Once the post is ready to put online, I take the XML file, run the PowerShell script against it and then copy it to my production server. Occasionally the XML files refuse to open in Internet Explorer after I ran the script. It took me few minutes to figure out why. Here is the story!

When you move into an XML-based publishing environment, the right approach can save time and even make new publishing paradigms possible if you properly design the structure. This article describes how you can convert documents designed for print publishing to structured documents. Discover the logical musts to ensure that publishing is achievable following a transition to XML.

Microsoft is sharing bits of Oslo at the Microsoft Professional Developers Conference (PDC) this week. Learn what's new in M, the company's language for creating domain-specific languages, and why Microsoft thinks it's such a big deal.

Today, I’m going to write about PHP, The most popular server-side scripting language. There are lots of articles & tutorials online that help novice PHP developers to learn PHP step by step. In this post I’ve listed some of the best PHP tutorials, articles & resources in some of the most important PHP skills. After reading the following tutorials and learning them (of course not all of them), you are free to name yourself a semi-professional PHP developer!

I have a Python application in which, for my sins, I decided to use XML as an on-disk storage format. Unfortunately, when I made this decision, I neglected to measure the performance of the available Python XML processing implementations.

This post describes How inheritance is used in XML Schema and how it is mapped to PHP code from wsdl2php tool.

This article revisits some XML basics, from document structure to the age-old attributes versus elements issue. You'll relearn how to optimize your XML and ensure it's in tip-top shape.

...I needed a quick and dirty way to do the deep clone of an object, since my entity classes are shared between WCF, WPF and Silverlight (yes I’m one of the guys so crazy to build multi-target applications) I needed a method that could work in all the environments...

Microsoft released Silverlight 2.0 yesterday, as expected. Part of the big exciting news is that you can now code up Silverlight applications in Eclipse. Yeah, not kidding. I know, you just hit weather.com too and checked to see what the temperature was. But seriously, Microsoft is fully supportive of the Eclipse environment

David Pollak was right about XML and JSON, but perhaps in a different way. XML cannot be converted to (clean) JSON.

This post gives a summary (With code examples) of some Tips and Tricks related to Apache Axis2 (Java). Apache Axis2 is a high performance Web Services Engine which supports both REST and SOAP style Web Services.

Today I will talk about creating Flash that is customizable to the end user. The problem with flash is that when something even as small as a spelling mistake needs to corrected; we need to go back in the IDE and change it. We developers and designers know that we don’t want to be bothered with this type of stuff, so we give the client the power to easily change the flash components.[...]

Adobe has released a new vector graphics specification for Flex called FXG, but some feel they should have kept with the standard SVG spec and extended it, instead of muddying the water.

I recently had a project that required a custom subset of data from a database be stored in an XML file. Each “row” of data also had a related image on a separate server. The project required that both the data and the image be transferred to a client for subsequent consumption by another program. In designing the project, it seemed unnecessarily complex to transport the data and the images as separate entities. Mostly the problem was that this process would simply add more moving parts, which would add to the complexity and increase the probability of “user inspired difficulties.”

Have you ever found yourself doing something like this in some code you’ve been writing?

SimpleXML is very simple and powerful in traversing XML. But there are situations where it is not the right tool to use. This is where xpath help you. This describe how you can use xpath inside simplexml environment and where to use it.

This gives a simple overview about the REST API for Twitter. This raise the question whether it is Really RESTful?

Although current databases limit XML processing to linear XPath or XQuery queries, existing hierarchical database techniques enable far more complex queries using standard SQL.

This article shows how it is easy to publish any graph of Java Objects to the web using simple annotations and without having to invent any new format. A simple example shows how one can publish a social network that links into the vast existing web of data. Jersey is the reference implementation of JAX-RS the Java API for RESTful Web Services.

The OpenLaszlo Incubator includes several useful components such tooltips, rich text editor, and the validators. I have blogged previously about the OpenLaszlo Incubator. The Incubator Directory opens up by providing background on the nature of the OpenLaszlo Incubator. That document explains that the incubator consists of OpenLaszlo components submitted by the community that have not been folded into the main OpenLaszlo framework because of reasons like lack of documentation, insufficient testing, or lack of code review. However, having said that, several of these components (including the tool tips and the validators) are widely used.
