Tuesday, 21 August 18: me, on ed(1), at SemiBUG

The headline pretty much says it all, but:

Next Tuesday, I’ll be presenting on ed(1) at the SouthEast Michigan BSD User Group, semibug.org. 7 PM, Altair Engineering.

I doubt that any user group or conference will want me to show up to talk about ed(1), even though it is the standard text editor. So, this is probably your one and only chance to see this talk.
