Here’s a wordle from a new paper accepted at ISSRE’10:

Two journal papers online

Heiko — Tue, 31 Aug 2010 14:44:40 +0000

Two journal papers with my co-authorship have gone online:
- Springer Journal on Empirical Software Engineering:
From monolithic to component-based performance evaluation of software architectures: A series of experiments analysing accuracy and effort [Preprint-PDF]
- Elsevier Journal on Performance Evaluation:
Performance evaluation of component-based software systems: A survey [Preprint-PDF]

Prezi presentation application

A possible replacement for PowerPoint? Prezi is a web-based presentation application and storytelling tool that uses a single canvas instead of traditional slides. Looks quite funny. Also see Wikipedia: Prezi.

Multi-tenancy Style

Heiko — Fri, 26 Feb 2010 08:13:49 +0000

Multi-tenant software applications serve different organizations from a single instance and help to save development, maintenance, and administration costs. Yesterday, I gave a talk on SE2010 in Paderborn proposing a new architectural style for multi-tenant systems:

The corresponding paper will be available here soon.

PerOpteryx

Heiko — Fri, 12 Feb 2010 08:35:42 +0000

Last week we visited WOSP/SIPEW 2010 in San Jose, US and presented the PerOpteryx approach. The approach is Anne’s PhD topic, which targets to automatically improve software architecture models for performance, reliability and costs using evolutionary algorithms:

More infos and tools can be found on the PerOperyx website.
