The toolbox section (navigate through the drop-down menu) is a collection of techniques, technologies, or concepts which I have heard and read about. It is more centered on specific "tools" than the StoriesStories section.
Although some of these "tools" have not gone through rigorous investigation, this section is a personal drop box to keep interesting information for further consideration - and obviously also to share them. In this at times anecdotic section I often mainly give links to further, extended information sources as well as the status of my understanding of the matter.
Keep in mind that I haven't investigated many of them into detail. The discarded tools are some that initially attracted my attention, but for which further reading or research has shown their inefficacy.
Feel free to contact me if you come across relevant information, so that I can add it.
