RGBLED, Color Management, and FireFox 3.5

Tags: ,

Just a short note. if you are using an RGBLED display such as in case of the Dell XPS 16 and you get strange colors looking on your flickr pictures etc using firefox 3.5, you have to deactivate the new color management:

  • type about:Config into the address bar
  • search for gfx.color_management.mode
  • set the value to 0 which deactivates the color management

… restart the browser.

A Transparent Semantic Enablement Layer for the Geospatial Web

Tags: , ,

We just finished a substantially extended and rewritten version of the poster accepted for EuroSSC 2009 (update: the paper was accepted, see below):

Abstract Building on abstract reference models, the Open Geospatial Consortium (OGC) has established standards for storing, discovering, and processing geographical information. These standards act as basis for the implementation of specific services and Spatial Data Infrastructures (SDI). Research on geo-semantics plays an increasing role to support complex queries and retrieval across heterogeneous information sources, as well as for service orchestration, semantic translation, and on-the-fly integration. So fa r, this research targets individual solutions or focuses on the Semantic Web, leaving the integration into SDI aside. What is missing is a shared and transparent semantic enablement layer for Spatial Data Infrastructures which also integrates reasoning services known from the Semantic Web. Focusing on Sensor Web Enablement (SWE) we outline how Spatial Data Infrastructures in general can benefit from such a semantic enablement layer. Instead of developing new semantically enabled services from scratch, we propose to create profiles of existing services that implement a transparent mapping between the OGC and the Semantic Web world.

Changing Your Mind – Why Not?

Tags:

Just a short comment. I am always surprised when some people criticize others for changing their mind? Isn’t this what science is about? We should always be flexible enough to learn new things and then change our opinion. What was a right (whatever this means) decision and useful some time ago may be not appropriate in a new context some time later. Nevertheless, this does not mean that we should not try to go new ways or try to develop unconventional solutions for (old) problems simply because all others go the same route again and again. Following our intuition and believes and still being flexible enough to correct them through learning is a strength and not a weakness – doing things simply because ‘this is how things are done’ is.

As one commentator has noted, science proceeds by funerals. (Ian McEwan from ‘What We Believe
but Cannot Prove’) ;-) .
