In the week since I was ejected from Google I have been spending a lot of time working on Radian. I had intended to put in the equivalent of full-time hours, but somewhat to my surprise I find it only takes 3-4 hours before I run out of code to write. There’s still a lot of thinking to do, and some of that thinking is best done as a background task while I focus my attention elsewhere. I can’t just power through it by thinking hard. I’ve been fitting the coding work into spare hours during evenings and weekends, but how much further would I have gotten if I had whole work-days available for this project? In terms of hours invested, there’s probably not more than half a year’s equivalent of full-time labor in the project, but there’s no way I could have solved my way through all these problems in that short a time even if it were the only thing I was doing.
