Henney is a member of the ACCU, and gave the keynote address at the 2001 ACCU conference on the subject of writing less code, because "there is no code faster than no code" and "less code, equals less bugs" (of which he is an active presenter). He is also a speaker at OOPSLA, most recently speaking at OOPSLA 2005. In October 2009, Henney presented The Uncertainty Principle at the 2nd Annual PHP North West Conference in Manchester, UK. He has also credited with the remark "...except for the problem of too many layers of indirection" in response to the famous aphorism of David Wheeler: "All problems in computer science can be solved by another level of indirection."
Another level of indirection.
