Mr. Lunduke talks about removing a reliance on Google services from your life -- why people feel it is necessary and how to go about it. Thanks to today's panel: Aaron Seigo - Past President of KDE, Evangelist & Senior Technologist at Kolab....
This talk is about an Open Source robot version of me that I use instead of commuting. It uses web technologies and cheap, off the shelf hardware to give good quality audio and video, and also allows me to move around a bit. It's particularly good...

Miles runs down the inner workings of the Ikawa sample roaster.
The insertion point pulses, waiting for input.
The roasting schedule feature was added in Typica 1.9 to make it easier for roasting companies to split the roasting work flow up among multiple stations. Previously, it was challenging to adopt a workflow other than having one person weigh the...
How I have Typica set up at a Diedrich IR-1 Profile Lab Roaster to record temperature, fuel setting, airflow setting, and communicate with a scale for measuring green and roasted weights. Since making this, I've also added [degree of roast measure...
Also known (unfortunately) as Rate of Rise, the rate of change of the temperature of a coffee during roasting can be used to more quickly notice when a batch is diverging from a roasting plan. This derived data series is most useful when calculate...
An overview of the annotation controls available in Typica. All of these are now in current release versions of Typica. You can also see an example of Typica communicating with simulated hardware on Linux using ModbusPal and tty0tty.
With Typica, it's easy to set up multiple coffee roasters such that measurements are presented in a way that's mutually calibrated. By presenting data such that development milestones appear to occur at the same temperatures, it's easier to match ...
This shows a very old version of Typica, data acquisition hardware that has become very expensive, and a coffee roaster that is no longer manufactured, but the basic concepts work for any coffee roaster that uses ungrounded thermocouples for tempe...
A short demo showing coffee roasting data with Qt Quick 2. This is how I'm able to zoom in on specific points of interest, compare different roasts, and otherwise use roasting data to illustrate concepts in my videos. Some day I'd like to have the...
Typica 1.8 changed how Typica logs who recorded which activities. This enabled a faster and easier way to switch the currently logged in user.
While it's almost always better to use Typica with supported data acquisition hardware, it's possible to use Typica without that and with some machines, particularly older sample roaster designs, the quality of measurements available may mean it m...
Walk through of my favorite feature introduced in PeerTube beta 9: the ability to wait until transcoding is finished before publishing a newly uploaded video.
The main data entry tasks for tracking green coffee inventory using Typica. Entering data accurately and consistently is key to getting usable reports based on that data.
