Leave a reply

Java LogoIn one of my previous articles I've dealt with creating Oracle (Sun) Java 6 packages for your favorite Debian based distro. Since Oracle Java 7 has been out for a while now and it's code has matured to the point of OpenJDK 7 being default in recent Linux distributions, it seems reasonable to upgrade. In this article I'll show you how to create Oracle (Sun) Java JRE and JDK 7 packages using Janusz Dziemidowicz packaging work from Java 7 binary files you have downloaded your self.

In this article I'll show you how to create Oracle (Sun) Java 6 packages from Java 6 binary files you have downloaded your self.

Prosody XMPP/Jabber logoI've been working on my Ajax chat system Quick Chat for WordPress for a while now. With Quick Chat I'm using technique called long polling to turn Apache Web server into chat server. This approach works fine most of the time when there aren't many concurrent chat users and server load is moderate. The reason for this is that Apache Web server is tuned for serving HTML. Better way of handling chat on your page is to install dedicated chat server software using XMPP (Jabber) protocol. This is protocol is used by big players like Gogole as well as Facebook for their chat services. XMPP is open protocol with many open source server and client implementations. In this article I will show you how to install and configure Prosody XMPP (Jabber) server on Debian/Ubuntu Linux based operating systems.
