In the course of getting a job done, we all end up doing a bit of research. Here are some of the projects I’ve contributed to, from artificial intelligence to aircraft design, tissue simulation, human-machine interfaces and Lego Mindstorms! Feel free to check it out. Wherever possible, I’ve added the presentation versions, which are a bit more visual and a lot less text!
This is a nice step-by-step guide on how to um, think… like a GIT.
If you’ve done any electronics hacking, designing, pondering, or frustrating, you may have googled your way to Bob Pease and one of his articles that follows the title format, “What’s all this XYZ Stuff, Anyways?” where XYZ is an arcane, important mystery of electrical engineering steeped in dogma, myth, and cloudy mystery. His M.O. is to blow all that fuzz away and leave clear understanding and core concepts. He’s one of those authors that make you feel smarter. Here are some of his articles from Electronic Design. They paywall many others, but they were nice enough to share some of the Best (by their reckoning) and the Control Systems ones are certainly of interest to me
“What’s All This P-I-D Stuff, Anyhow?”
“What’s All This Double-Clutching Stuff, Anyhow?”
“What’s All This Negative Feedback Stuff, Anyhow?”
“What’s All This Spicey Stuff, Anyhow? (Part II)”
“Bob’s Mailbox: Audio Quality, A Crazy Rack, And The PE Exam”
“What’s All This Input Impedance Stuff, Anyhow?”
“What’s All This Current Limiter Stuff, Anyhow?”
If you like watching him chat it up and seeing the demos, his videos by TI and others are all over youtube, which I am sure he could have replicated using 6 op amps and a pair of LEDs.
When I was a kid, we got those great little flip books with a record or tape included. The tape had all the narration and sound effects of, say Return of the Jedi, and the book had the accompanying snapshots from the movie. You knew it was time to turn to the next page in the book when the audio tape made a ‘beep’ or if the production team was clever, a lightsabre noise.
This is well and good when quickly mapping a 2 hour movie into a 20 page kids book with a cassette tape inside the front cover, but not so good when working in the reverse and using source material like EG: an epic drama that asks Big Questions about meaning of dominance and empathy as seen through a bullied genius-child bred to save humanity, like, say Ender’s Game.

Great podcast – Ira, the host of SciFri, asks some poignant questions, trying to get around the usual, ‘I am sure you’ve been asked every question’ and puts Chris. Hadfield onto a few great lines of thinking. Well worth the listen.
The highlight for me was the discussion about the concept of being right at “the edge of the possible” and how that is a universal motivator that so many innovators see embodied in space exploration.
jsperf is like a horserace – it allows you to set up and run your own test cases simultaneously on multiple remote browsers to see the performance differences. One recent one I was checking out was “Math.floor(4.6)” versus “~~4.6″. This is a powerful tool to diagnose some cross browser performance issues, and to have a look at what other people have been benchmarking.
