OpenFire is an opensource real time collaboration server that use XMPP (also called Jabber) to create istant messaging applications.
The official web site also says “Openfire is incredibly easy to setup and administer, but offers rock-solid security and performance” and I can confirm you that it’s really true!

We’ll use the Arduino microcontroller and an analog joystick to control two servos: the first one will be connected to the horizontal axis, and the second one to the vertical axis.
We also use a the Lynx B-Pan Tilt Kit (BPT-KT) to connect servos together. Check the video and imagine what kind of robots or cool stuff you could create using more devices and a lot of pacience ; )

In this article we’ll use the Adobe Collaboration Service components (codeName : CoCoMo) to develop a simple eLearning platform with following features:
1) WebCam
2) Audio on/off
3) User List
4) Text Chat
5) Shared notes
6) Shared whiteboard

Cocomo - Common Collaboration Model - è un servizio Adobe, attualmente disponibile a titolo gratuito sul sito Adobe Labs, che permette agli sviluppatori Flex di realizzare applicazioni di collaborazione in tempo reale, sincronizzando dati, audio e video.
E’ possibile creare quindi giochi multiuser, audio e video conferenze, chat testuali, pubblicare file condivisi tra più utenti, condividere lavagne, Collection, note e molto altro grazie ai componenti già inclusi nel framework, simili in tutto e per tutto a quelli disponibili nel servizio Adobe Connect
