Welcome to

Rick Cogley Central

Thanks for stopping by! This is where I write about my experiences with the technology and tech techniques I use, my hobbies & pasttimes, and my life in Japan.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
—Robert A. Heinlein

I've been helping businesses and visitors in Japan since 1987, and am the co-founder and CEO of eSolia Inc, my IT management firm. I like to create, manage, negotiate, drum, run, cycle and pay attention to the details. More oversharing on my , if you're so inclined.

I hope you'll find something informative in my content.
