title: The Chi problem
date: 09-Oct-2025
Much has been said about the word sometimes written as 'Chi' in English (pronounced the same as in the English word 'cheese'), corresponding to the Chinese character 氣. This character, pronounced 'chi' in Chinese, 'ki' in Japanese, 'khi' in Vietnamese, 'gi' in the Philippines etc and corresponding closely with the Indian word 'prana' is variously translated as 'energy' in the sense of vital life-force, or 'élan vitale' from the French.

So, fairly regularly something turns up in my inbox relating to Shu-Ha-Ri (守破離) often quoted as a Japanese model of skills acquisition. These articles, blogs etc. are all problematic in some way or other, and inevitably as both an Aikido instructor and a career IT professional with deep experience of Software Development Methodologies, I will get asked what I think. Hmmm...

So I read a bit about Tennis, and thought 'Hey, that sounds cool, I'd like to learn that', and looked around to see if there is a local Tennis club, and if there is a learners' group. Great news, I find a 'Learn Tennis' session run by a local instructor. They appear legit, are certified and insured by the Tennis Union of Great Britain, so I go down on Tuesday evening to the local sports centre and give it a go.

preamble: An open letter to Mr. Binstock and Dr. Dobbs addressing their recent editorial entitled "The Corruption of Agile" and its follow-up article addressing feedback from the community.
EDITED: 2024-10-29 in order to fix broken links and to use the Internet Archive in order to make available material which commercial publishers have egregiously removed - see Fox's 8th Law[^7]. Sadly it appears that my closing hope was not upheld over the intervening decade by the recipients.
Dear Mr. Binstock,

The problem with #FOSS (Free and Open Source Software) is that everybody thinks they know what it means. I once spent a couple of years working on and off with Ross Gardler, a VP of the Apache Software Foundation and Manager of OSS-Watch in Oxford.
