March 13, 201968: test && commit || revert (TCR) - Thomas Deniffel
With conventional TDD, you write a failing test, get it to pass, then refactor.
Then run the tests again to make sure your refactoring didn't break anything.
But what if it did break something?
Kent Beck has been recommending to commit your code to revision control after every green test run.
Oddmund Strømme suggested a symmetrical idea to go ahead and revert the code when a test fails.
Kent writes that he hated the idea, but had to try it.
Then wrote about it last September.
And now we have TCR, "(test && commit) || revert".
What's it feel like to actually do this?
Well, Thomas Deniffel has been using it since about a month after that article came out.
In this episode, we'll hear from Thomas about his experience with it.
It's a fascinating idea. Have a listen and let me know what you think.
Special Guest: Thomas Deniffel.

February 28, 201967: Teaching Python in Middle School
In today's episode we talk with Kelly Paredes & Sean Tibor.
They teach Python in a middle school in Florida, and talk about this experience on the podcast "Teaching Python".
I love that they include physical computing right from the start, and everything else they are doing.
It's a fun interview.
Special Guests: Kelly Paredes and Sean Tibor.

February 26, 201966: Brian is interviewed by Phil Burgess
I was recently interviewed on a podcast called "IT Career Energizer Podcast".
Phil Burgess is the host of the podcast, and it was a lot of fun.
I think it turned out well, and I wanted to share it with you here, with Phil's permission, of course.
Special Guest: Phil Burgess.

February 17, 201965: one assert per test
Is it ok to have more than one assert statement in a test?
I've seen articles that say no, you should never have more than one assert.
I've also seen some test code made almost unreadable due to trying to avoid more than one assert per test.
Where did this recommendation even come from? What are the reasons?
What are the downsides to both perspectives?
That's what we're going to talk about today.

February 07, 201964: Practicing Programming to increase your value
I want you to get the most out of being a software developer, or test engineer, or whatever you do that makes this podcast relevant to your life.
By "get the most" I mean:
the most fun
the most value
more career options
probably more responsibility
maybe even more money, that'd be cool
I want you to start (or continue) studying and practicing your skills.
But not just random practice, I've got a strategy to help you focus what to study.
Why am I talking about this now? Here's some background on how I re-learned how to have fun with code refactoring through code challenges.
I'm going to write up the whole list as a blog post, which I'll share first with my Patreon Supporters, second with my email list and slack channel and then as an actual post somewhere.

February 01, 201963: Python Corporate Training - Matt Harrison
I hear and I forget.
I see and I remember.
I do and I understand.
-- Confucius
Matt Harrison is an author and instructor of Python and Data Science. This episode focuses on his training company, MetaSnake, and corporate training.
Matt's written several books on Python, mostly self published. So of course we talk about that.
But the bulk of the conversation is about corporate training, with Brian playing the role of someone considering starting a corporate training role, and asking Matt, an experienced expert in training, how to start and where to go from there.
I think you'll learn a lot from this.
Special Guest: Matt Harrison.

January 13, 201962: Python Training - Reuven Lerner
There are a lot of learning styles and a lot of ways to learn Python. If you started Python through a class at work, or through an online course, or maybe an email series, it's possibly you may have learned from Reuven Lerner.
If your first encounter with pytest was reading an article in Linux Journal recently, that would be the writing of Reuven.
Reuven Lerner teaches Python.
This interview definitely falls into the category of talking with interesting people doing interesting things with Python.
We talk about how incorporating testing into teaching can add a level of clarity to the interaction and help people duirng the learning process.
I'm also fascinated by people who teach and train because it's a skill I'm trying to improve.
