Prototype è una classe javascript nata in seno al progetto ruby on rails, questa classe è stata poi talmente apprezzata che gli sviluppatori ne hanno esteso la compatibilità a tutti i linguaggi.
La principale forza di Prototype è appunto la facilità di gestione e manipolazione dei dati [vedi esempi 1, 2, 3] e la possibilità di essere utilizzata quindi efficacemente con tecniche ajax per lo sviluppo di applicazioni web.

The second Release Candidate of PHP 5 is now available! This mostly bug fix release improves PHP 5’s stability and irons out some of the remaining issues before PHP 5 can be deemed release quality. Note that it is still not recommended for mission-critical use but people are encouraged to start playing with it and report any problems.
Key changes since Release Candidate 1 include:
* The Zend Engine I compatibility mode (zend.ze1_compatibility_mode) has been re-implemented to more accurately support PHP 4’s object auto-clone behavior.
* All object-oriented extensions except for MySQLi have moved to studlyCaps. This includes SQLite, SOAP, Reflection API, Ming and others.
* Implementing an interfaces and/or abstract method with the wrong prototype is now a fatal error. For backwards compatibility, re-implementing regular methods with the wrong prototype will only result in an E_STRICT warning.
* Features as described in the Release Candidate 1 release announcement
* And lots more…For changes since Release Candidate 1, please consult the ChangeLog.

What is the IBM Emerging Technologies Toolkit (ETTK)?
The ETTK is a software development kit for designing, developing, and executing emerging autonomic and grid-related technologies and Web services. The ETTK provides an environment in which to run emerging technology examples that showcase recently announced specifications and prototypes from IBM’s emerging technology development and research teams. In addition, it provides introductory material to help developers easily get started with development of autonomic technologies, Web services, and grids. The ETTK evolved from the package known as the Web Services Toolkit (WSTK). With the renaming of the WSTK package to ETTK, the scope of technologies included within the package has been expanded. The new toolkit consolidates related technologies from various IBM development and research labs. The demos and functions of the ETTK run on both Linux and Windows® operating systems.
How does it work?
The basic software components needed to experiment with and create Web services and autonomic and grid-related programs are provided with the ETTK. Included is an architectural overview of autonomic technologies, Web services, sample programs, utility services, and some tools (such as ReGS Autonomic Logging demo, XML Parser, UDDI client APIs) that are helpful in developing and deploying autonomic and grid programs and Web services. The toolkit also includes a fully-functioning SOAP and grid infrastructure.ETTK includes a fully-functioning SOAP engine (Apache AXIS), and grid (Globus ToolkitTM) infrastructure.
