Abusing Amazon Dash Buttons
A recent talk I gave about using Amazon Dash buttons for off-label purposes.
Home Automation with openHAB
Natural Language Processing for Smartphones
I just gave an NLP talk. If you’ve ever wondered why your smart phone’s voice assistant seems to be thrown for a loop if you stray from the pre-approved phrasing, this will explain why.
Gene Therapy Breakthrough
I’m not in the medical research field, but here’s a recent talk that I gave about some breakthroughs in gene therapy. As a software engineer, I’m fascinated by how analogous the process is to patching software.
Open Senses: Open Source Robotics Software for non-Robotic Uses
Time Machine Alternatives for Linux
I recently gave a short talk about what I discovered while looking for Linux alternatives to OSX’s Time Machine. There are a few solutions in there, from DIY shell commands all the way up to full GUIs with scheduling and housekeeping functions.
Addendum: I had been doing mirror-style rsync backups of user accounts previously, sometimes while the user was logged in. This had never presented a problem. When I switched to doing incremental backups, users reported being unable to start an X session. (Ok, they reported “my password doesn’t work,” but I was able to log in remotely via ssh; the basic login action was working fine.) It turns out that the .Xauthority file was becoming corrupt if I did an incremental backup while the user was in a active X session. The safest way around this is to only do incremental backups of user accounts while the users are logged out. This is probably the safest policy for other reasons as well, but when your users are on machines that are often only turned on while they’re in use, it’s less convenient to do it this way.
Glasses and Sunglasses in 2013

Passive House Design
I just gave a talk on the basics of Passive House design. Check it out if you’re interested in learning about the future of construction 🙂
Real-world Automation with Arduino
My CPOSC 2012 talk about automating real-world tasks with Arduino, featuring a garage door opener that knows when you’re home, and a treadmill that knows when you’re on it.
