My new book Nginx Module Extension is now out on all major online retailers. You will find this as a one stop guide to getting familiar with nginx module system and how to install and configure HTTP and 3rd party modules. The unique thing about this book is a chapter on how to write your own nginx module. Open source is all about creating for yourself and others what doesn’t already exist. Hope nginx users and developers will find it useful.
Losing your software user’s attention is a matter of seconds, or probably just one second. That is why you must strive very very hard to make sure the application has sub-second response times. Speed of your application, is still The Killer Feature. Here is why
I have been confused about this for half a month until i figured this out. So what is Anti-Caching? And why is it needed? How is it different from the traditional buffer-pool system in all the databases today?

You will basically be told Chrome does not support Java 7 on the Mac platform.

Since the use of multi-core computers / PCs is common these days, there are more and more parallel programming frameworks coming up. If you use Scala (or Java) you might have used the AKA framework which is based on Actors. In java 7 there are the Fork/ join APIs. However you might ask why do we need these , since multithreaded apps are already quite common. If you use Servlets and so on you are automatically using multiple threads and JVM is a beast when it comes to scaling up using threads and utilising multiple cores. Continue reading
If you want to write a custom Nginx module, Emiller’s guide is a very good starting point. This article is a wee bit long and you might want to get your hands dirty just to see a full program. In this case you can find this hello world module useful.
I have seen too many web services (and done a few) where fault handing is not user friendly / graceful. Most of the times the way people code the web services using annotations or using POJOs in frameworks like Axis2 the SOAP faults just contains an error message since this is the easiest thing to do. However for clients this is not too friendly as they can only do error handling based on your error strings. SOAP 1.2 specifications here , provide a better way of populating your SOAP faults. That is to provide at-least SOAP codes, sub-codes and a fault string as well as details (if possible). This is old news, but i still thought should be talked about. Continue reading
