109: Resurrection of Extreme Programming

James Grenning (@jwgrenning) returns to discuss TDD, Agile, and web courses. 

James was on Embedded.fm episode 30: Eventually Lighting Strikes.

James' new company is Wingman Software.

His excellent book is TDD for Embedded C

James suggested Training From the Back of the Room! as resource to people looking to put together a class. He uses and recommends CyberDojo as a coding instruction tool.

Before Agile was Agile-for-business, it was Extreme Programming. James recommends Extreme Programming Explained.

James will be the keynote speaker at AgileDC in October.

108: Nebarious

Jen (@RebelbotJen) joined Chris and Elecia to discuss security, privacy, and ethics in wearable computing. 

Elecia's Linker post is especially relevant this week: Device Security Checklist..

There is already a standard for privacy and security: HIPAA (Title II). While not easy to read, it is a reasonable starting place. Another good (but not quite on-point) resource is the EFF Secure Messaging Scorecard, especially if you consider your device as messaging your user (it's a metaphor, ok?). Also, read all the way to the methodology, not just the pretty checkboxes.

Mike Ryan has great explanations for how to easily crack BLE security. Video to watch. His website has more resources, papers, videos, tools.

The Embedded Systems Conference (Silicon Valley) will be held at the Santa Clara convention center July 20-22. 

Casino article: Breaking the House

Chris and Elecia were guests on The Amp Hour

Jen is interested in putting together a workshop/conference on the intersection of art, dance, and technology. Contact her on Twitter or email info at rebelbots dot com. 

107: Until They Are Spaghetti

We talked to Craig Cook about learning embedded systems. He recently attended an embedded edX course through University of Texas.  

The microcontroller and boards used in the course

Craig's next course will be Interactive Python through Coursera

As we discussed Craig's alarm clock we mentioned many parts including:

Chris has also been looking at Particle.io's Photon board for WiFi + cloud development. This will be mentioned on other shows (as well as on The Amp Hour).

104: Only the Paranoid Survive

Atmel’s Andreas Eieland (@AndreasMCUguy) spoke with us about low power chips and benchmarks, including tips for measuring and achieving the lowest power possible.

EEMBC has a low power benchmark: ULPBench. EETimes wrote up a great introduction to the benchmark. Atmel’s SAM-L posted some excellent numbers for ULPBench.

Chris wanted to look at processors between Cortex-M4 and phone chips. Andreas suggested the SAM7, SAM E, and Cortex-A5.

Programmable logic blocks (Look Up Tables)

Coding tips and tricks for AVR micros (most things apply for all embedded development)

App Note: Ultra Low Power Techniques

App Note: Performance Levels and Power Domains

Andreas was also on Episode 15: Robot on the Front, speaking about how the AVR processor line came to life, why there is an AVR in Arduino, and the spirit of making things.

The Planet contest ends Friday June 12 (at midnight your time). Check out their jobs and send in your contest entry.

Also, check out Elecia’s BLE Intro.

103: Tentacles of the Kraken

Mark VanderVoord (@mvandervoord) spoke with us about leading open source projects and test driven development.

His site is ThrowTheSwitch.org, a good place to get started with test driven development. Get more info (and a coupon) for his course. Mark's book is Embedded Testing with Unity and CMock

102: The Deadly Fluffy Bunny (with Wifi)

Charles Lohr spoke with us about $5 WiFi (ESP8266), hacking as a hobby, arcade games, and music visualization.

Updated 06/02/2015: A listener pointed out that the Arduino IDE can program the ESP8266, probably an easier setup than Charles' original article. Also, the Linker post for this show is about getting started with BLE.

Follow Charles on YouTube (or say hello on Google+ and Hackaday.io). To get you started, here are Elecia's favorites:

101: Taking Apart the Toaster

Micah Elizabeth Scott (@scanlime) spoke with us about Coastermelt, art installations, FadeCandy, teaching electronics to artists, and mental health. 

Her Toronto International Film Festival (TIFF) installation is mesmerizing, some videos

In her Coastermelt project, Micah uses the IDA disassembler.

FadeCandy is for sale at Adafruit.

Zen Photon is online, demonstrating ray tracing.

Micah's website shows her current projects. 

Micah's previous Embedded.fm episode focused on FadeCandy: 41: Pink Universes Die Really Quickly.

Robot Odyssey looks awesome.

Captain Awkward is a site where you can get advice on how to say things and deal with difficult situations/people.

Micah's shop has a TypeA 3D printer (note: Tuco's favorite bolts) as well as an OtherMill

100: Unintentional Radiator

Star Simpson (@starsandrobots) and Jen Costillo (@RebelbotJen) catch up with Elecia and Chris, discussing how hobby projects have changed over the last two years since the show started.

99: You Can Say a Boat

Andrei Chichak spoke with us about MISRA-C and ethics. 

Linker post: It's dangerous to go alone! Take MISRA-C

Embedded.fm listener survey (please!)

Andrei's has personal website (we failed to talk about his kite aerial photography, it is really neat though) and his company is CBF Systems.

Plum Hall C Compiler Validation

PC Lint

JPL Coding Standards for C (and the mentioned video discussing Mars Code)

ISO 26262 Automobile software standard

Cortex-R for high reliability systems (ARM's description)

National Society of Professional Engineers code of ethics and Canadian Engineering Guidelines on the Code of Ethics

Offline, Andrei recommended two books and another podcast about MISRA:

 

98: Figments of My Imagination

Chris and Elecia talk about memetics, learning, and processors. 

Elecia was coy about the Pasadena party May 9th and 10th, but Hackaday announced it so you can invite yourself. She will also be speaking at the Solid conference in June in SF (email for a coupon!). She'll also be at ESC-Silicon Valley in July

Star Wars Teaser #2 and SpaceX almost-landing

BLE fun: TI's CC2640 and Nordic nRF51822 (Elecia likes the BLE Nano with the free, online mbed compiler for getting started with the nRF5122).

Everything seems to be a Cortex-M0 these days (including the aforementioned CC2640 and nRF51822). The new Atmel SAM-L series is Cortex-M0 and even more low power than usual. On the other hand, the MSP432 is low power and is a more powerful Cortex-M4 (and inexpensive dev kits!),

Elecia has a book: Making Embedded Systems. It makes a great gift.

 

97: Bubblesort Yourself

Professor Paul Fishwick joined us to talk about CS and STEM education, excellent analogies, and the crossover of art and technology. 

The Linker post related to this episode managed to be reasonably topical for a change.

Paul's work:

 Radiolab Color Episode

Forrester System Dynamics

Max is a visual programming language for music and multimedia.

CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. 

There are many bubblesort dance videos (mindboggling) but this is the one Elecia knew about previously.

The Computer History Museum is awesome. If you are in the area, you should definitely go.
