Learning biofeedback
On and off for the past few months I've been practicing biofeedback so that I can increase circulation to my hands and feet on demand. (Biofeedback is about learning to control what would normally be autonomic bodily processes. Some people do it with expensive equipment, but if you have good body awareness like I do you may be able to do some of it without even a thermometer for feedback.) And the cool thing is, it's working! I had a really dramatic experience a week or two ago when I had just gone to bed and wanted to warm up my legs. I relaxed while "pushing" heat towards my legs, and within a minute I started to feel prickling, and then a throbbing sensation over the entire surface of my legs. (It subsided after maybe 10-20 seconds, and then my legs were just warm.) How awesome is that?

Ameliorating the effects of malware in a web of trust
Let's say it's the future, and everyone has at least one public key and is a full participant in a global web of trust. Wonderful, until EvilWorm9000 hijacks your mail client and starts spamming everyone within 4 degrees of separation. How does the ideal network respond? In this post I provide a possible approach (temporary key tainting), but the main goal here is to stimulate a conversation.
