Yes, that would be Carl’s “day to day” blog (http://rescue1130.blogspot.com/). 
He is also on the list, lurking in the background. Carl, are you there?
Ken Shirriff has also several deeply researched blog articles on specific AGC

Mike has some very interesting posts on his AGC FPGA emulation work here:

The project and videos were mentioned on the list back in December.
There's an interview with Jimmie there (4:13) with more details about the 
backstory.
