The cat has declared it is now hug time.

It's 2:08AM. The cat is requesting cuddles.

Put together a new figure for chapter 2. This takes screenshots from two batches on the IKAWA: one with control based on exhaust temperature, the other controlled by inlet temperature. The plans are such that on one coffee it resulted in my color change and crack events happening at the same time, same overall roasting time, same whole bean and ground degree of roast measurements. Under the screenshots are graphs of the heater setting through each roast (which the app doesn't show).

Accountant was out today to work on my tax stuff. Asked her if there was a sales level for the book where we should review my tax situation. Got an answer.

All my todos are removed from chapter 1. I'm hoping to do the same with the rest of the book and get it out for technical review about a week from now. While I'm waiting on feedback I'll be spending more time on the business side of getting ready to sell the book. Hopefully everything goes smoothly and people can get the finished book early March. In the final stretch.

I just made that stack and the cat walked up to it and *shove*

Cat decided to knock over a stack of books.

Hello, cat.

Requested the printer print something. It went through the motions of moving the paper but deposited no toner at all. Let's try that again.

Picked a name for my publishing company, purchased ISBNs. I'll be publishing my books through Roasting Book Press. The name didn't seem to be taken and I already own the domain.

I'm trying to be selective here, preferring things that are easy to find and affordable (free is considered affordable) rather than packing in a ton of citations to out of print stuff that exists in maybe 2 or 3 libraries in the US or stuff in expensive paywalled journals.

Rather than a terse bibliography I've decided to go with a section at the end of each chapter with recommendations for further reading that goes into a little more depth in terms of what you should be looking for in other resources so the reader can better decide if that's something that's going to be useful for them.

Some of the less important photos don't look great, but I've tested the ebook on a thing without color and all the text is still easy to read. Some of the graphs are challenging without color, but still readable with context. Probably the worst is the opening photo of chapter 5.

The cat is making clicky noises.

Spam just recommended giant plush vampire.

The cat is snoring.

I suspect that even better results would be available if the control algorithm were changed to operate on cubic splines instead of linear splines when matching exhaust temperatures, but since I'm not about to try reverse engineering a firmware upgrade for the machine to create that capability the closest I could do to test that would be using a stupidly large number of control points input through a phone app that's very clearly not designed for plans that detailed.
