August 26, 2017opsdroid with Jacob Tomlinson
Summary
Server administration is an activity that often happens in an isolated context in a terminal. ChatOps is a way of bringing that work into a shared environment and unlocking more collaboration. This week Jacob Tomlinson talks about the work he has done on opsdroid, a new bot framework targeted at tying together the various services and environments that modern production systems rely on.

Your host as usual is Tobias Macey and today I’m interviewing Jacob Tomlinson about opsdroid
Interview
Introductions
How did you get introduced to Python?
What is opsdroid and what was the problem that you were trying to solve when you started the project?
What led you to choose Python as the language for implementing opsdroid?
What did you find lacking in the multitude of other chat bots that necessitated starting a new project? (e.g. Hubot, Errbot, Lita)
One of the main features that you list in the documentation is the ease of installation. Why is that such an important aspect of the project and how is that implemented?
What has been the most interesting and the most challenging aspect of implementing opsdroid?
On the opsdroid organisation on GitHub there are many repositories for plugin modules. Do you see this being a management issue in the long term?
How is opsdroid architected and what were the system requirements that led to the current system design?
How do you manage authorization and authentication for performing commands against your production infrastructure in a group chat environment?
What are some of the other security implications that users should be aware of when deploying a bot for interfacing with their deployment environment?

How does a chat-oriented bot framework differ from those that are being created for voice-oriented interaction?

What do you have planned for the future of opsdroid?

August 20, 2017 Ergonomica with Liam Schumm
As developers we spend a lot of our work day in a terminal window, using shells that were designed 30 years ago. This week Liam Schumm joins me to explain why he decided to write a new, more ergonomic shell environment to simplify his workflow.

August 12, 2017 Data Retriever with Henry Senyondo
Analyzing and interpreting data is a large portion of the work involved in scientific research. Getting to that point can be a lot of work on its own because of all of the steps required to download, clean, and organize the data prior to analysis. This week Henry Senyondo talks about the work he is doing with Data Retriever to make data preparation as easy as "retriever install" .

How did you get introduced to Python?
Can you explain what data retriever is and the problem that it was built to solve?
Are there limitations as to the types of data that can be managed by data retriever?
What kinds of data sets are currently available and who are the target users?
What is involved in preparing a new dataset to be available for installation?
How much of the logic for installing the data is shared between the R and Python implementations of Data Retriever and how do you ensure that the two packages evolve in parallel?
How is the project designed and what are some of the most difficult technical aspects of building it?
What is in store for the future of data retriever?

August 06, 2017 Coverage.py with Ned Batchelder
We write tests to make sure that our code is correct, but how do you make sure the tests are correct? This week Ned Batchelder explains how coverage.py fills that need, how he became the maintainer, and how it works under the hood.

Your host as usual is Tobias Macey and today I’m interviewing Ned Batchelder about coverage.py, the ubiquitous tool for measuring your test coverage.
Interview
Introductions
How did you get introduced to Python?
What is coverage.py and how did you get involved with the project?
The coverage project has become the de facto standard for measuring test coverage in Python. Why do you think that is?
What is the utility of measuring test coverage?
What are the downsides to measuring test coverage?
One of the notable capabilities that was introduced recently was the plugin for measuring coverage of Django templates. Why is that an important capability and how did you manage to make that work?
How does coverage conduct its measurements and how has that algorithm evolved since you first started work on it?
What are the most challenging aspects of building and maintaining coverage.py?
While I was looking at the bug tracker I was struck by the vast array of contexts in which coverage is used. Do you find it overwhelming trying to support so many operating systems and Python implementations?
What might be added to coverage in the future?

July 30, 2017 Yosai with Darin Gordon
For any program that is used by more than one person you need a way to control identity and permissions. There are myriad solutions to that problem, but most of them are tied to a specific framework. Yosai is a flexible, general purpose framework for managing role-based access to your applications that has been decoupled from the underlying platform. This week the author of Yosai, Darin Gordon, joins us to talk about why he started it, his experience porting it from Java, and where he hopes to take it in the future.

Darin Gordon about Yosai, a security framework for Python applications
Interview
Introductions
How did you get introduced to Python?
What is Yosai and what is the problem that you were trying to solve when you started it?
How does Yosai compare to existing libraries for web frameworks such as Flask-Security or Django Guardian and why might someone choose Yosai instead?
In the documentation it mentions that Yosai is a port of the Apache Shiro framework from Java to Python. What was most difficult about exposing a Pythonic interface while maintaining the core principles of the original?
Authentication and authorization are difficult problem domains and can cause significant issues if they are not implemented in a secure fashion. How do you ensure an appropriate level of quality in Yosai to be confident having people use it?
To start can you describe how the framework is architected and what is involved in integrating it with a project?
Outside of the context of web applications, what are some situations where someone should consider integrating authentication and authorization into their project?
What have been some of the most challenging aspects of building the Yosai project?
Tell us about the Rust extension you wrote earlier this year
What do you have planned for the future of Yosai?

July 22, 2017 Moving to MongoDB with Michael Kennedy
There are dozens of decisions that need to be made when building an application. Sometimes this can lead to analysis paralysis and prevent you from making progress, so don't let the perfect be the enemy of the good. This week Michael Kennedy shares his experience with evolving his application architecture when his business needs outgrew his initial designs.
