I love how it was already clear that it would be Raymond Chen's blog just from the title and domain name. I really enjoy The Old New Thing and his coverage of obscure details that might otherwise be long forgotten.
His blog is the best, especially when he talks about ancient versions of Windows. He talk about obscure details, but they're so interesting because they give you insight on how things were made!
I’m impressed he remembers the minute details, I can’t recall what I did last month.
Not sure about Raymond Chen’s memory capabilities but carefully maintained notes are an effective substitute.
Well, I also can't recall what I did last month, but if you put me in front of an Apple II+, I know I can get into the machine language monitor with "CALL -151".
