Demonstration of Android at Google IO 2008. I apologise for the camera shake but this is worth seeing. Watch out for the Google Street View integrated with on-phone compass at the end of the video.

Functional Programming with Python
Python is a general-purpose, very high-level programming language. Its design philosophy emphasizes programmer productivity and code readability. Python's core syntax and semantics are minimalist, while the standard library is large and comprehensive.
Python supports multiple programming paradigms (primarily object oriented, functional, and imperative), and features a fully dynamic type system and automatic memory management; similar to Perl, Ruby, Scheme, and Tcl.
Python was first released by Guido van Rossum in 1991. The language has an open, community-based development model managed by the non-profit Python Software Foundation. While various parts of the language have formal specifications and standards, the language as a whole is not formally specified. The de facto standard for the language is the CPython implementation.

Ruby on Rails Security
The slides from the 24C3 session "Ruby on Rails Security" by Jonathan Weiss, 30.12.2007.
Even though Ruby on Rails introduces a lot of best practices to the developer, it is still quite easy for an imprudent programmer to forget that every web application is a potential target. Web application attacks like Cross Site Scripting or Cross Site Request Forgery are very popular these days and every Rails developer should have an idea about the different possibilities that his application presents to an attacker.
This talk will cover most of the common web application vulnerabilities like Cross Site Scripting and Cross Site Request Forgery, SQL and Code injection, and deployment security and how they apply to Rails. Further Ruby on Rails specific issues like Rails plugin security, JavaScript/Ajax security, and Rails configuration will be examined and best practices introduced.
