I still have one more roast to finish and a bunch of measurements to take and numbers to crunch, but so far it looks like what I expected to see out of today's experiment is supported by the evidence (that one control strategy does, in fact, produce less variable results across different coffees, meaning I have a recommended practice for improving sample roasting consistency on that machine).
Doing some #SaturdaySciencing today. Given an automated coffee roasting system with two different parameters control can be based on, a plan on each such that events happen at the same time, same total roasting time, does one control strategy have less variation in degree of roast across coffees with different physical characteristics (moisture, bulk density, &c)? Let's find out.

Fixed a problem with the online ordering where it would allow orders to be placed that can't successfully be charged under some circumstances. In one case I was able to fix the customer's input failure and process the order, but today's order couldn't be repaired and I just had to cancel it. Now the system should just reject the order with a meaningful error message and let the customer try again.

Some automated system just kicked out a three year old meeting cancellation email. The really strange thing here is that the mail server that sent that didn't even exist back then so I'm assuming someone is migrating something and tried to preserve pointlessly stale data through the process for some inexplicable reason instead of just cutting over to a fresh system.
