Interview
Introductions
How did you get introduced to Python?
What is Home Assistant and what was the initial frustration that inspired you to create it?
How useful would home assistant be for someone who doesn’t have a lot of the so-called ‘smart home’ technology?
Given the fact that the intended context for Home Assistant is in the user’s house or apartment, how do you ensure that their data and privacy are safe?
Reading through the documenation for installing and configuring Home Assitant, it seems prohibitively complex for someone who is not technically inclined. Has any work been done to try to package the project in a way that is more friendly to a casual user?
What are some of the most difficult challenges that you have faced while building Home Assistant?
Why did you choose Python 3 as the technology for building this platform?
The list of supported services and integrations is quite impressive. How does the current architecture allow for that kind of growth?
How has the architecture of Home Assistant evolved from when you first started it?
What are some of the products or platforms that you consider to be competitors of Home Assistant and how do you differentiate yourself?
What are some of the most interesting or unexpected uses of Home Assistant that you have seen?
What do you see as some of the most promising and the most troubling trends in the future of home automation?

Interview with Paul Kehrer
Introductions
How did you get introduced to Python?
Can you share a bit of the background behind the Python Cryptographic Authority and how you got involved?
There is an adage that you should never roll your own crypto because if there are bugs or exploits in your implementation then it can have potentially serious side effects. What problem was the Cryptography library created to solve that was important enough to proceed despite that risk?
Given the sensitive nature of the libraries that you are working on, what development practices are you relying on to prevent the introduction of vulnerabilities?
While reading through the documentation I noticed that Cryptography links against OpenSSL. Is it possible to swap that out for alternative implementations such as LibreSSL or S2N?
What are some of the testing techniques that you use to ensure the accuracy of the algorithms that you are using?
What are some of the factors that a developer should keep in mind when selecting which cryptographic library to use in their projects?
When might someone want to use the capabilities found in the cryptography library what do they need to be aware of while writing their application?
For someone who wants to incorporate the cryptography library into their project what are some of the potential pitfalls that they should be aware of and how much knowledge of encryption should they possess?
In what ways does the security landscape in Python differ from that of other languages that you are familiar with and what unique challenges do we face?
What are some of the fundamental aspects of encryption and cryptography that you feel every developer should at least be aware of?
If anyone wants to learn more about security and encryption, what resources do you recommend?

Your host as usual is Tobias Macey and today I’m interviewing Dwayne Bailey and Ryan Northey about Translate House and the process of internationalization and localization for software projects.
Interview with Dwayne Bailey and Ryan Northey
Introductions
How did you get introduced to Python?
Why did you get involved in localisation, what got you started?
How would you describe the difference between internationalization and localization? Are there cases where it makes sense to only do one of those things?
Why should people localise software into other languages?
Translate House is an organization focused on localizing and internationalizing software projects. To that end there are a collection of projects that you develop and maintain. Can you briefly introduce each of them and describe their purpose?
What was the first project that was created in that list and how did it lead to the creation of the other tools?
At what point did you decide that creating an organization to own and support the tools that you were building was the right choice to make?
You run a distributed organisation, how do you manage that?
I was recently speaking with Michal Čihař about the Weblate project and he mentioned that he uses the Translate Toolkit for handling the low level aspects of managing the translation files. What are some of the architectural and design challenges that arise from needing to support so many different systems for managing source text and translations?
How do Pootle and Virtaal compare to other tools for web or desktop based translation? Are they primarily used for translating software or do they get used for other sources of text as well?
Given that Virtaal is intended for use on desktop systems by people who aren’t necessarily technically adept how have you approached the packaging and deployment aspects of it? What are some of the challenges that you have had to overcome?
Given the fact that multi-lingual translation requires interacting with a large quantity of text in numerous alphabets, what kind of impact has the unicode handling in Python 3 had on your projects?
What do you have planned for the future of your projects?

Interview with Martijn Faassen
Introductions
How did you get introduced to Python?
What is Morepath and what problem were you trying to solve when you created it?
The tag line for the Morepath project is that it’s a web microframework with superpowers. What is special or different about it that sets it apart from the other options in the Python ecosystem?
It can be difficult to convince someone to migrate to a new framework, particularly if there is a lack of supporting ecosystem. What are some of the motivating factors for a developer to switch to Morepath if they already have experience with one of the more widely used frameworks?
What does the internal architecture for Morepath look like and what are some of the challenges that you have faced while building it?
One of the features is the automatic link generation for ensuring that you don’t end up with dead links. Is there any support for permalinks or redirects so that if you refactor your site people won’t end up at a path that no longer exists?
In the documentation you make a number of references to the fact that Morepath is a routing based framework. Can you explain what you mean by that and how it differs from a traversal based framework?
Part of the core elements of Morepath are your libraries Reg and Dectate. Can you describe each of them and explain some of how they came to be created?
Morepath has a different conception of models than most frameworks that I’ve dealt with in that they aren’t necessarily associated with any form of database. Can you explain why that is and some of the patterns that it allows for?
The method for extending and reusing applications built in Morepath is through subclassing the objects and overriding specific methods. What is it about this approach that you found to be more flexible than the alternatives exhibited by other frameworks?
What are some of the most interesting or unexpected uses of Morepath that you have seen?
What do you have planned for the future of Morepath?

December 31, 2016 ERPNext with Rushabh Mehta
If you need to track all of the pieces of a business and don’t want to use 15 different tools then you should probably be looking at an ERP (Enterprise Resource Planning) system. Unfortunately, a lot of them are big, clunky, and difficult to manage, so Rushabh Mehta decided to build one that isn’t. ERPNext is an open-source, web-based, easy to use ERP platform built with Python.
