1. ## New Years Data To DB - The Model and The Data

For some reason I never seem to be able to remember the formula for combinations and find myself looking it up again. At some point, probably after you had mentioned it, I gave myself a refresher, notes from which led to writing of COMBINATIONS.TXT. It is satisfying to arrive at some such conclusion based only on the problem at hand, then to find that you have reinvented another wheel - successfully. Reinventing wheels is a very useful exercise, so long as they are round in the end! It would be much less satisfying to simply memorize everything, and forget why it works...

Thanks for the comment!

2. ## New Years Data To DB - The Model and The Data

What i find especially satisfying here is seeing a formula for C equating to 715 combinations in our case. I now see that, without realizing it at the time, i was indeed following the above formula for C in finding 715 unique combinations of 4 digits.

5. ## Down The Rabbit Hole... Chapter 1

Letterpress type on bond. Tactile trace while reading. My earliest memory of *books* is things like this, but not so famous. Well done.

Wow! What a treasure. Over budget for something so beautiful and lucky to find is a non-issue now since they are all but irreplaceable.

Oh man! I didn't know that either... sad to see that, but glad to have shared their time on the planet! I think I'll pull out some old vinyl and spin it up, in memoriam.
