I'm a retired software engineer, who specialized in system software, particularly operating systems. I'm Canadian, but live in California; I moved here for a better selection of work available, not to mention somewhat more money for the same work than in Canada. I don't recall exactly how I came to subscribe to your blog, but my usual route is that someone else signal-boosted posts of yours, which I liked enough that I decided to subscribe for myself. Most likely the signal booster was on Dreamwidth.
