I used to be a Theoretical Physicist but after getting my PhD in 1980, I recovered. My path into the real world was by becoming a UNIX systems programmer and I have been fascinated by operating systems ever since which I guess could be classified as an illness. However, academia, in the form of UCL Computer Science Department, pulled me back in, mostly so I could research into programming and programming languages with emphasis on object orientation, concurrency, parallelism and human factors. I spent some fun time teaching programming and software engineering, researching and climbing the academic ladder.
I seemed to be headed towards a cushy life until retirement when an old friend approached me and said "Oi, you, why don't you take this really serious challenge" which led me leaving academia, becoming Chief Technology Officer at OneEighty Software Ltd and bringing the ORIGIN technology into the world. Unfortunately, one of the funders of the company got cold feet (or got nobbled by our competitors) and pulled the financial plug so the company went into liquidation.
I am now an independent consultant and technical author. Wiley's seem to have confidence in me as an author as they have published:
