188: Twitter Is a Cocktail Party

Scott Hanselman (@shanselman) of the Hanselminutes Podcast talks about technology podcasting and philosophy.

You can find Scott's blog on Hanselman.com/blog and his other podcasts on Hanselman.com/podcasts.

We talked about Hansleminutes' WebVR episode with Ada Rose Edwards and Alcohol and Tech with Victor Yocco. We also mentioned Scott's blog post from 2014 about what technologies he would learn if he had to start over.

187: Self-Driving Arm

Crossing machine intelligence, robotics, and medicine, Patrick Pilarski (@patrickpilarski) is working on smart prosthetic limbs.

Build your own learning robot references: Weka Data Mining Software in Java for getting to know your data, OpenIA Gym for understanding reinforcement learning algorithms, Robotis Servos for the robot (AX is the lower priced line), and five lines of code:

pred = numpy.dot(xt,w)                  
delta = r + gamma*numpy.dot(xtp1,w) - pred  
e = gamma*lamda*e + xt                  
w = w + alpha*delta*e                   
xt = xtp1                                   

Patrick even made us a file (with comments and everything!).

Once done, you can enter the Cybathlon. (Or check out a look at Cybathlon 2016 coverage.)

174: It's Not Weird

We spoke to Evan Shapiro, CTO and cofounder of Knit Health (@KnitHealth), about baby monitors, IoT security, neural nets, and professional poker.

The Knit Health Kickstarter ends November 17, 2016.

Evan recommended Google Tensor Flow and Python's Theano for an introduction to machine learning. (If those sound familiar it is because Kat Scott mentioned them as well.) Evan also suggested that if you'd like to know more about the history of neural nets, check out this post by Audrey Korenkov

If you'd like a gentle introduction, check out a Narwhal's Guide to Bayes' Rule.

Evan mentioned some videos he did about poker, they are on Card Runners (NOTE: it is a paid site with free tastes).

Final quote was from Neil Gaiman's excellent Graveyard Book.

172: Tell Forth You Me Please

James Cameron of One Laptop Per Child (OLPC) tells us about Forth, science fiction, and laptops.

We have some tickets for ARM's mbed Connect conference is Oct 24, 2016 in Santa Clara. Will you be in the area? Want to go? Contact us if you want one of our free tickets! (There are still some tickets remaining.) 

One Laptop Per Child is one.laptop.org

Some getting started information on Forth: Mitch Bradley's Forth and Open Firmware Lessons

James has been writing about putting C Forth on a Teensy (more on the Teensy from the creator's site). He also has a post on using Forth to snoop the Milo Champions Band's BLE

James is Quozl on most sites that require a unique ID (such as Github:  https://github.com/quozl). This is from a book called Quozl by Alan Dean Foster. The other older-sci-fi reference was to the Pern books by Anne McCaffery, specifically to the White Dragon

 

 

171: Perfectly Good Being Square and Green

Saar Drimer of Boldport (@boldport) spoke with us about the crossover of art to electronics and building a business around it. 

Monthly, the Boldport Club ships aesthetically-pleasing electronics kits. We discussed past projects include The Lady and Touchy on the show. The seahorse board is on the blog.

Micah Scott (@scanlime) has entrancing videos of putting together the first club project (Pease) and second one (Superhero).

Saar uses PCBMode to create his circuits. He also wrote the tool. It is open source.

Cratejoy is used for the sales and shipping logistics.
