Rack talk by Christian Neukirchen   06 Dec 07

We use rack at personifi. Highly recommended simple elegant and fast!

Developing general web frameworks and frameworkless web applications is difficult because lots of different ways to connect to web servers need to be implemented. Since Ruby is popular for writing web applications, we try to address this problem by proposing a lightweight abstraction mapping HTTP requests onto a simple Ruby API. This makes it possible to combine all kinds of web servers with different web applications without further change. Furthermore, our solution enables new functionality by combining and composing web applications, as well as better testability. Talk given at the European Ruby Conference (Euruko) 2007.

APFP (Arbitrary Precision Floating Point)   09 Apr 07
[print link all ]
APFP (Arbitrary Precision Floating Point) is an Unicon class for performing arbitrary precision floating point calculations. It also includes a class for calculating with arbitrary precision complex numbers. It requires unicon overloaded operators. It also contains a ureal class for built-in reals. Both classes keep an estimate of the accumulated error.

Changes: This is the first Ruby version. The design is much cleaner. Error tracking and complex numbers are not yet completed.
