Keeping Up with Python: the 2.2 Release

Python 2.2 resolves some well known deficiencies of the language and introduces some new powerful constructs that are key strengths of other object-oriented languages.

Although all these new features and weakness resolutions bring Python pretty far down the path, there are those who claim that they violate Python's simplistic nature. If you're stictly a purist, that is probably a valid consideration. However, by finally purging some of the annoyances and adding a few more powerful constructs to the language, we are probably better off than we were before. These changes will not have a negative impact on existing code, and those that do, such as the change in the division operator, are at least not required for some time and allow for a more painless transition.

Finally, see Resources for a couple of other high-level documents, such as Andrew Kuchlin's “What's New in Python 2.2” and the slide presentation from one of Guido's talks last fall at a Python user group meeting. Python 2.2.1 can be downloaded at the main Python language home page. Happy hacking!

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
