Will do. Makes sense. It will show the difference, although not how it
works.

I wish I had asked you and you had mentioned it months ago. That is a
fantastic blog! Not only is it clear, but he shows hex structures and
assembly, and colour-codes things to make it understandable.

He did. It is much appreciated.

I have been a bit nervous about doing so. Especially since all of this work
is "on the side" OSS, and not part of work (I spend my days consulting on
cloud product strategy and operations, devops transformations, etc. - but
the engineer in me always is the engineer in me), afraid to go down that
rabbit hole!

Deeply appreciative again, Ady.
