Roasting for Espresso
Today I got an email asking for my thoughts on roasting for espresso and I thought that readers here might be interested in my approach to that. This is most of my reply in which I largely don’t answer the question.
—
It’s very rare that I will roast anything specifically for use as espresso. That isn’t to say that you might not want to do something different when...

Cost of Green for Roasted Coffee Reporting
Today I spent some time working on a new report for Typica. This one calculates the cost of green coffee per unit of roasted coffee. Implementation is simple. First it acquires a list of the roasted coffee items you currently produce. This is the same as the list of roasted coffee items in the New Batch window so if you’ve been keeping that current there’s no extra data entry that...
Assorted Random Stuff
As those who follow me on twitter already know, this morning I finished up the last of the work needed on the rate of temperature change stuff in Typica. I think there’s still some room for improvement on that, but I’m not going to hold a release for minor tweaks to that. It’s an optional feature, you have to turn it on under Configure Roasters, click on the roaster you want to...

DATAQ Hardware Support Status and Graphing Rate of...
Today I spent some time working on merging support for the DATAQ DI-145 into Typica. That support is currently slightly awful since it’s pretty much a straight merge from the initial work on that from Typica 1.3, but that is in a working state (but you’d need to have a custom configuration to actually use it since there isn’t any in-program configuration of that yet) so I have a...

Rate of Change Update
Today I finished integrating the rate of change calculator in Typica such that you can go into your roaster configuration, set up an indicator, and have that show up when you roast coffee. Well, at least if you’re using Typica built from the development branch, which you aren’t so maybe it’s better to say that I can do that, and I did, and now that I have the feature available, I...

Rate of Change Indication
As anybody who has asked about the technical details of implementing it themselves in Typica knows, I’ve put a fair amount of thought into how one might implement a rate of change (also known as rate of rise or sloppily as just Δ) indicator in Typica. Today I’m putting that into practice so the feature will be ready to go for the next release of Typica. The code itself is trivial and...

Yesterday I made a modification to Typica that allows scripts to be informed when certain links in web views were clicked. Today I’ve been messing around with using that feature. Early on I decided that this would be more useful if I could modify the content of the web view without having to regenerate all of it. That meant allowing access to instances of QWebElement from scripts so I added...

Drill Down Reporting Enabled in Typica
Today’s big update to Typica’s development branch replaces QWebView with a new TypicaWebView subclass. This removes all of the script functions that were previously added as properties when accessing a web view from the host environment and makes them proper Q_INVOKABLE class methods that the meta-object system just makes available to scripts automatically. It also adds a new signal...

Certification Status
I had previously intended to only finish the first level of the Roasters Guild certification program this year but some things changed that prompted me to accelerate my progress through that program and pick up both certification levels this year. I’ve been working with SCAA staff to figure out how to do that. At the recent SCAA expo I finished several requirements and it looks like...

Civet poop coffee may be threatening wild species →
If the poor value or the thought of drinking shit weren’t enough to dissuade you from trying kopi luwak, think of the cute wild animals who are being treated cruelly to produce this entirely unnecessary product.
Also, journalists, please stop hyping this.

How to Pack Open Liquor Bottles
At the recent SCAA expo I was given the bottle of scotch seen a couple posts back. I decided to try a bit of this before leaving Boston, but drinking all of it within a couple days would have been a mistake so I was left with the problem of transporting an open liquor bottle on an airplane. Here’s how you do it:
Put the cap back on the bottle as tightly as you can.
Take some tape. I used...

Are you sure? →
One of the early design philosophies of Typica is that the program does what you tell it even if I don’t think that’s generally the best course of action. This is mainly because I was initially writing this only for my own use and sometimes doing what is generally ill-advised is, in fact, the right thing to do. For some time now I’ve been unhappy with the balance between letting...

Expo Plan
Tomorrow morning I’ll be flying to Boston for the Specialty Coffee Association of America’s 25th annual exposition. I’ve been going over my notes and it looks like this will be the busiest expo schedule that I’ve set for myself yet. I’ll need to remember to take it a little easier next year.
Thursday I arrive in Boston in the morning and take the bus from the airport...
