HTTP chunked transfer-coded data read / decode example in C++

Posted Sun, 03/03/2013 - 22:35 by Uditha Atukorala

I was writing some code for the bitz-server project the other day and I wanted to read data passed in using the Chunked Transfer Coding (RFC 2616, section 3.6.1). I did some quick googling but I couldn't find a coding example in C++ (or in C).

In the RFC 2616, section 19.4.6, there is a pseudo-code example on how to decode "chunked" transfer-coding, which seemed simple enough. So I thought of implementing it myself.

This is my approach to implementing a "chunked" tranfer-coding decoder in C++.

FormCheck with MooTools v1.3

Posted Wed, 20/07/2011 - 16:09 by Uditha Atukorala

FormCheck is an awsome MooTools class that allows you to validate XHTML form fields on cliet side. It has a nice UI touch and the validations are pretty good. I have been using it for some time now but the latest version (at the time of this writing), version 1.6, was released back in March 2010 and it only works with MooTools version 1.2.

This level includes several patterns. Such as commitment pattern – describe future event, policy – business rules, responsibly- structure of the agent and custody- responsibility for resources.  (Hruby, 2006)

Wireless Local Area Networks - Design and Implementation

Posted Sat, 13/11/2010 - 10:45 by Uditha Atukorala

Today we have 802.11n wireless networks with up to 150 Mbps data rates but still we hardly see wireless implementations as an alternative to wired LANs. Why? Is it because wireless networks are unreliable? Or is it because of the data rates?
