It's been over 20 years since the last update to HyperCard was released. When I was in the 4th grade I taught a small class on that. It was pretty neat because the people who wanted to make it do stuff could easily get into the coding side of things and the people who just wanted to draw stuff on the screen could do that, too.
Roasting system calibration is something that I've done a lot of work on in developing Typica so it's good that there's external research happening at a larger scale that confirms the results of the work I've done, and having a class where people can prove it to themselves is great to see.
Had an online run through on a class I'll be helping out with in a couple weeks. I've station instructed this one a couple times before but it's good to know where things are going to be. The students in my group will be trying to roast a coffee such that they're indistinguishable in the cup between a Diedrich and a Giesen roaster. Should be fun.
I see the typo and I'm leaving it. What part of the ship people watch or don't watch my videos from is not any of my concern.
Over on YouTube the latest episode of Coffee and Code is now both the most liked and most disliked (but not mast viewed) episode in the series. People should be watching it over on PeerTube instead. https://video.typica.us/videos/watch/e41dd13a-3071-4bc4-9b2c-b2cd76f18499
While I'm building this to update a class, I should probably talk about this in a future episode of Coffee and Code because it touches on something that's being discussed right now, it's an interesting experiment that anybody with a roasting machine can replicate, and it shows a strong consistency with things that I've been saying about coffee roasting over the past decade that's in conflict with popular misinformation.
Collecting some data to illustrate some more advanced coffee roasting concepts and I just did an 8 minute roast to an end temperature of 502F (about 40F hotter than my darkest production roast). 22.4% mass loss, gourmet scale 20.5. I don't recommend replicating that at home (if you want it that dark, it's probably better to spend more time and get there at a lower temperature).
