Jen Costillo (@rebelbotjen) joins Elecia and Christopher to discuss their experiences interviewing (both as interviewer and interviewee). Elecia did an hour long webinar on how to conduct technical interviews. In this show, she mentions a good post-interview ratings system. Google discovered that their brainteasers are not a very effective way to interview. Despite the news that swearing is good for you, we tried to bleep everything. Also, it is minesweeper, not minefield. What were we thinking? It was obviously all Christopher’s fault. Though we should have stood up to him.  Elecia's book has more interview questions but from the perspective of how do you ask a question and what do you look for in a response.

This week we talk about CircuitPython (@CircuitPython) with @adafruit’s Kattni Rembor (@kattni) and Scott Shawcroft (@tannewt).  The suggested first board is CircuitPlayground Express with LEDs, sensors, and buttons. CircuitPython is also available for many other boards including the BLE Feather (NRF52832). For a basic introduction take a look at What is CircuitPython and see some example scripts. To dig a little deeper, check out the many resources in Awesome CircuitPython. The whole thing is open source so you can see their code. If you are thinking about contributing (or just want some fun chats), get in touch on the CircuitPython channel of the Adafruit Discord server: adafru.it/discord Many of the language’s design choices favor ease-of-use over ready-for-production. Imagine teaching an intro to programming class without worrying what computers will be used or how to get compilers installed on everyone’s machines before time runs out.  One final note: Kattni did a project that gave us the show title: Piano in the Key of Lime. After we finished recording, Chris asked her why she didn’t add a kiwi fruit to her mix… Kattni explained she had limes and they were small. Chris only wanted a different fruit so she could rename it Piano in the Kiwi of Lime. It is always sad when we stop recording too early.
July 11, 2019
Mike Harrison (@mikelectricstuf) challenged us to a PIC fight on Twitter. Surprisingly, no blood was shed and we mostly talked about LEDs and art installations.

Elecia wrote about her love of notebooks on the https://www.embedded.fm/blog-index. yEd, for when you don’t have Visio. Asciiflow.com, for when you don’t have yEd (or you want to put diagrams in your comments) We talked about many different documents and tried to note design vs implementation, product vs engineering vs user, and why we wanted them. We didn’t mention mechanical things because, ya know, software engineers. Some documentation we mentioned: Product documentation Schematics with block diagrams and comments. Also a GPIO to function spreadsheet. UI flow when the system has a screens (Balsamiq for wireframe testing UIs) SW spec and design doc: what do we plan to build and what are the tricky parts SW configuration and SW developer docs: how to rebuild the computer that can build the code from scratch, also notes on debugging methodology User manual: Usually not written by SW but may need SW’s patient input Code comments: Functions and files get 5Ws: who, what, why, when, where, and how. Who should call this? What will its effect be? (“What will it do” but not in line by line detail!) How does it work? Why does it work this way? When should it be called? Where are its parameters? (“What” works here too but “where” is nice to remind you to check your memory assumptions.) Repository checkin comments Style guide (Such as Google’s or PEP) Manufacturing docs and tests docs   Adafruit and Sparkfun both write good documentation, writing to users about how to use their code. Elecia likes Adafruit’s sensor library as a good set of code to review (including how much is in their docs vs their code).
