Five Podcasts to Put You to Sleep

Years ago I lost the ability to fall asleep in silence. I require consistent background noise in order to drift off. I’m not alone here; many people can’t get to sleep without some kind of ambient sound in the room. My son uses a fan for this purpose. An old girlfriend of mine (number three, for those keeping track) showed me her standby, the sleep timer button. “All hotel TV remotes have a sleep timer button,” she informed me one night. “How do you not know that?” She could get mouthy. I don’t use a fan or television to fall asleep. I use podcasts on my iPhone. And here are my five favorite podcasts for that purpose.

Cloud Security Crucibles: Australia and New Zealand

I’ve just returned from a long tour of Australia and New Zealand (ANZ), where some exciting developments are worth capturing. Both countries are island nations, and one thing Darwin noted in “On the Origin of Species” is that islands can become crucibles of evolution. Australia is evolving a new way to leverage cloud, and New Zealand is evolving a new efficiency model for government security services. Both countries share one aspect with the rest of the world: challenges around encryption.

5 Ways to Make Back the American Express Platinum Annual Fee

For the first few years, I had to talk myself into paying the $450 annual fee for American Express Platinum card. This little piece is me getting talking myself into it on paper, as it were. The math checks out. And if anyone is keeping score, I still get the platinum card every year, and it pays for itself.

2006 Colorado Fishing Trip Report

My parents live in the town of Montrose, in Western Colorado, which is very close to some of the best fishing in the rockies (so I've heard). When we arrived there the first thing I did was head to the local fly shop (Cimmarron Creek) for the skinny. All over the rockies this time of year, they said, you have to deal with runoff. Basically you have to limit yourself to fishing tailwaters which will be somewhat protected as the flow is regulated. So they directed me to the East Portal in the Black Canyon of the Gunnison.

2006 Oregon/Idaho Fish Trip Report

From September 23rd to the 27th, I accompanied Jim Speaker on a fishing trip that he'd been planning for some time. In general I can say that the fishing varied from merely great to fantastic. In five days I fished Beda Lake (WA), The Owyhee River (OR), Silver Creek (ID), Big Wood River (ID) and East Lake (OR). That's a different location every day and in most of those cases each destination was hundreds of miles from the previous. I put 1800 miles on my truck and caught rainbows, browns and even a kokanee in a desert lake, a muddy tail water, a fabled spring creek, a mountain stream and a volcanic crater lake.
