C Vu articles

I wrote for the ACCU.org members-only journal “C Vu” (ISSN 1354-3164, not formally peer-reviewed but well-edited) starting from 1995. I found it to be a good learning environment: if I wrote an article with a misunderstanding, someone would correct it (and the journal being members-only reduces the odds of that situation later being misjudged by an overly-hasty potential employer or similar). The journal’s style has changed a bit since the early days. Here is a list of my articles for reference.
