My personal blog can be found at dw2blog.com.
It contains posts on my wider interests, such as AI, general software, collaboration, education, philosophy of science, philosophy of mind, quantum mechanics, cosmology, the multiverse, progress, evolution, history, skepticism, transhumanism, life extension, climate change, and the Singularity.
Older portions of that blog also contain work-related postings from before the creation of Symbian-specific blogs.
