ejabberd STUN Server

ejabberd is now much more Jingle friendly with its STUN server.

STUN (Simple Traversal Utilities for NAT) is a powerful address/network discovery tool, that can helps NAT traversal, which is the main requirements for a media(audio/video) sessions.
NAT traversal techniques are required for peer-to-peer and Voice-over-IP (VoIP) applications. Most techniques requires discover services from a publicly-routable IP address.
STUN is a method that uses the server only when establishing the connection, which saves bandwidth costs server-side, decreases latency and also boosts quality.

Jingle protocol uses STUN in a very efficient and easy way, making STUN the perfect combination for Jingle enabled Clients in order to provide peer-to-peer and great quality media sessions.

IM Status Message

Many people use their status messages of IM clients and micro-blog to express their feelings.
Looks pretty cool and very often you have the response or support that you want.
Some weeks ago I had a discussion with a friend about the actual meaning of a feeling can easily get lost in so short chunk of characters.

So today I put on my status text: "Biggest mistake of nature: Incompetence doesn't hurt."
I was actually making reference to a news where cops missed shots and hit innocent people, injuring some and killing one.

But it turns out, that the floating and vague phrase had impact in several colleagues and even ex-colleagues on my roster. Asking what was going on, if any project/people was failing, delayed or something.

I still think that the beauty lies in the eye of the beholder, and the same sentence can have several meanings if read by several people.

So before you put status message about DRM for instance: "I hate you, you MUST die!", you should be careful, as besides people are not sure about it. In fact it pops up a doubt and the attention of everyone in your roster: "Who is he referring? Would be me?". The same thing can happen if you put "I Love You!". For sure there are some people that you definitely don't want to think this is for them.
Remember, your status will be showed usually to all your friends and co-workers.

In the other hand status messages shows themselves as really powerful broadcast tool, use it wisely, so you can get also very fast and good results with it.
