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.

You'll get less coffee to coffee variation on interior degree of roast and less astringency distracting from what's really available in the cup.

Added a few more pages of book now that I've finished the analysis of last weekend's experiment. If you're working on an IKAWA Pro V3 sample roaster, I can now pretty confidently say that you should draft your control plans based on exhaust temperature which within similar control strategies correlate better with significant roasting events, but then export that data to your favorite spreadsheet and design a simpler inlet temperature control plan.

The house a couple down from mine has a really nice front garden. On the way to work today I saw a black cat heading up the stairs to enjoy that.

What happens to giant robot pilots when they retire?

Decided to enter a little coffee roasting competition. I swept the last one I entered but this time around I'm kind of hoping for third place.
