Episode 71 - GenSim with Radim Řehůřek

Summary

Being able to understand the context of a piece of text is generally thought to be the domain of human intelligence. However, topic modeling and semantic analysis can be used to allow a computer to determine whether different messages and articles are about the same thing. This week we spoke with Radim Řehůřek about his work on GenSim, which is a Python library for performing unsupervised analysis of unstructured text and applying machine learning models to the problem of natural language understanding.

Episode 70 - Python on Windows with Steve Dower

Summary

In order for Python to continue to attract new users, we need to have an easy way for people to get started with it, and Windows is still the most widely used operating system among computers. Steve Dower is the build maintainer for the Windows installers of Python and this week we spoke with him about his work in that role. He told us about the changes that he has made to the installer to make it easier for new users to get started and how modern updates to the packaging ecosystem for libraries has simplified dependency management. He also told us about how the Visual Studio team is building a set of tools to make development of Python code more enjoyable and how Microsoft's adoption of open source is making Windows a more attractive platform for developers.

Interview with Steve Dower

  • Introductions
  • How did you get introduced to Python? - Chris
  • You are currently the release manager for Python on Windows. How did you end up with that responsibility? - Tobias
  • While Python has supported Windows for a long time, the overall experience has historically been rather poor. Can you give a bit of the background of why that was and tell us about some of the work that you and others have been doing to make it better? - Tobias
  • Given that a large percentage of users are still on Windows, having a good story for getting started with Python on that platform is important for adoption of the language. What are some of the areas where the current situation needs to be improved? - Tobias
  • What is the most difficult part of building a distribution of Python for a Windows environment? Has it gotten easier in recent years? - Tobias
  • When we were speaking at PyCon you mentioned that the most frequently downloaded version of Python from the python.org site is the 32 bit version for Windows. Do you think that is an accurate and useful metric? What other statistics do you wish you could capture or improve? - Tobias
  • How does Python Tools for Visual Studio compare with other Python IDEs like Pycharm? - Chris
  • What are some unique features that Python Tools for Visual Studio offers that other tools don't? - Chris
  • Are there any compelling aspects of developing Python on Windows that could convince users on other platforms to make the switch? - Tobias
  • Could you give our listeners a whirlwind tour of the underlying implementation of PTVS? How does Visual Studio provide such in depth introspection for your Python code? - Chris

Episode 65 - Mypy with David Fisher and Greg Price

Summary

As Python developers we are fond of the dynamic nature of the language. Sometimes, though, it can get a bit too dynamic and that's where having some type information would come in handy. Mypy is a project that aims to add that missing level of detail to function and variable definitions so that you don't have to go hunting 5 levels deep in the stack to understand what shape that data structure is supposed to be. This week we spoke with David Fisher and Greg Price about their work on Mypy and its use within Dropbox and the broader community. They explained how it got started, how it works under the covers, and why you should consider adding it to your projects.

  • Introductions
  • How did you get introduced to Python? - Chris
  • Can you describe what Mercurial is and how the project got started? - Tobias
  • How did you get involved with working on Mercurial? - Tobias
  • What are some of the features that can be found in Mercurial which are lacking in similar tools such as Git or Bazaar? - Tobias
  • One of the common complaints with Git is that its human interface could use some work. How is Mercurial's UX an improvement over Git? - Chris
  • For someone who is using Mercurial to work with a Git or other VCS repository, what are some of the edge cases that they should watch out for? Are there certain operations that could be performed in Mercurial which would break that compatibility layer? - Tobias
  • How is Mercurial architected and what are some of the design choices that allow for it to be so flexible and extensible? - Tobias
  • One of the core goals of Mercurial is for it to be safe. Can you explain what safety means in this context and how it is architected to achieve that goal? - Tobias
  • One of the noteworthy aspects of Mercurial is the strong focus on making extensions a first-class concern in the project, so much so that a number of the core functions are written as extensions. Can you describe why that is and how the extensions plug into the core execution engine? - Tobias
  • What are some of the most notable extensions that are available for use with Mercurial? - Tobias
  • For someone who is familiar with Git, what are some of the concepts that they would need to learn about in order to use Mercurial in an idiomatic way? - Tobias
  • A large part of the reason that Git has seen such large adoption is due to the prevalence of GitHub. There is the option of using BitBucket when using Mercurial. Are there any other noteworthy Mercurial hosting options? Do you think that the dearth of open source mercurial servers is partially due to the fact that Mercurial ships with a functional server built in? - Tobias
  • Can you share some of the most recent features that have been added to Mercurial? - Tobias
  • What do you have planned for the future of Mercurial? - Tobias
  • How do you think current day DVCS systems like Mercurial, Git and Darcs might evolve in the future? - Chris

Visit our site to listen to past episodes, support the show, join our community, and sign up for our mailing list.

Summary

If you need to work with images the Pillow is the library to use. The Python Image Libary (PIL) has long been the gold standard for resizing, analyzing, and processing pictures in Python. Pillow is the modern fork that is bringing the PIL into the future so that we can all continue to use it moving forward. This week I spoke with Alex Clark about what first led him to fork the project and his experience maintaining it, including the migration to Python 3.

Summary

If you are responsible for managing any amount of servers, then you know that automation is critical for maintaining your sanity. This week we spoke with Tomaž Muraus and Patrick Hoolboom about their work on StackStorm, which is a platform for tracking and reacting to events in your infrastructure. By allowing you to register actions with event triggers it frees you from having to worry about a whole class of concerns so that you can focus on building new capabilities rather than babysitting what you already have.

Interview

  • Introductions
  • How did you get introduced to Python? - Chris
  • What is StackStorm and what problems does it solve? - Tobias
  • What was your inspiration for creating StackStorm and what were some of the biggest architectural and design challenges? - Tobias
  • What made you choose Python for StackStorm's implementation rather than another language like Go? - Chris
  • Can you describe the architecture of StackStorm and what the setup looks like? - Tobias
  • Other than chat driven events, what types of event sources does StackStorm support, and what use cases do those alternate event streams enable? - Chris
  • The home page describes StackStorm as being an event-driven framework for automating the users infrastructure. What kinds of capabilities are made possible by this and do you think that it simplifies or complicates the work of operations engineers? - Tobias
  • Is there a minimum or maximum size of infrastructure for which it would make sense to use StackStorm? - Tobias
  • It looks like StackStorm is made up of a number of discrete components. What do the components use to communicate, and how did those choices influence the design of StackStorm's overall architecture? - Chris
  • I use SaltStack in my work which is a tool that also focuses on event-driven architecture. Can you compare and contrast the capabilities and focus of StackStorm with the features of SaltStack? Would it make sense to use both frameworks in the same infrastructure? - Tobias
  • One of the advertised features of StackStorm is a strong focus on ChatOps. Can you explain that concept for people who might not be familiar with it and describe why it is such a useful paradigm? - Tobias
  • Extensibility is a critical capability for an operations platform due to the wide variety of environments that people are inclined to build. In StackStorm the unit of extensibility is a pack. Can you describe what a pack is and how you arrived at that abstraction? - Tobias
    • Have you encountered any situations in which the concept of a pack has been the wrong abstraction and made something more difficult than it may have been otherwise? - Tobias
  • In very large scale environments like Netflix, how would one build a StackStorm cluster to handle the immense load. More specifically, how does one determine what kinds of machine resources each component needs? - Chris
  • Management of credentials is always a difficult problem in operations. Does StackStorm attempt to tackle that issue or does it defer that responsibility to other systems, such as the user's configuration management platform? - Tobias
  • Does StackStorm interface with Kibana, Splunk or other log / metric aggregation packages? - Chris
  • What are some of the most surprising uses that you have heard of from people using the platform? - Tobias

Episode 52 - Hypothesis with David MacIver

Visit our site to listen to past episodes, support the show, join our community, and sign up for our mailing list.

Summary

Writing tests is important for the stability of our projects and our confidence when making changes. One issue that we must all contend with when crafting these tests is whether or not we are properly exercising all of the edge cases. Property based testing is a method that attempts to find all of those edge cases by generating randomized inputs to your functions until a failing combination is found. This approach has been popularized by libraries such as Quickcheck in Haskell, but now Python has an offering in this space in the form of Hypothesis. This week, the creator and maintainer of Hypothesis, David MacIver, joins us to tell us about his work on it and how it works to improve our confidence in the stability of our code.

  • Introductions
  • How did you get introduced to Python? - Chris
  • Can you provide some background on what Quickcheck is and what inspired you to write an implementation in Python? - Tobias
  • Are there any ways in which Hypothesis improves on the original design of Quickcheck? - Tobias
  • Can you walk us through the execution of a simple Hypothesis test to give our listeners a better sense for what Hypothesis does? - Chris
  • Have you had trouble getting people to use Hypothesis? How has adoption been? - David
  • What does this sort of testing get you that conventional testing doesn't? - David
  • Why do you think this sort of testing hasn't caught on in the Python world before? - David
  • Are there any facilities of the Python language that make your job easier? Are there aspects of the language that make this style of testing more difficult? - Tobias
  • What are some of the design challenges that you have been presented with while working on Hypothesis and how did you overcome them? - Tobias
  • Given that testing is an important part of the development process for ensuring the reliability and correctness of the system under test, how do you make sure that Hypothesis doesn't introduce uncertainty into this step? - Tobias
  • Given the sophisticated nature of the internals of Hypothesis, do you find it difficult to attract contributors to the project? - Tobias
  • A few months ago you went through some public burnout with regards to open source and Hypothesis in particular, but circumstances have brought you back to it with a more focused plan for making it sustainable. Can you provide some background and detail about your experiences and reasoning? - Tobias
  • What's next for Hypothesis? - Chris

Episode 51 - Pyjion with Dino Viehland and Brett Cannon

Visit our site to listen to past episodes, support the show, join our community, and sign up for our mailing list.

Summary

In an attempt to improve the performance characteristics of the CPython implementation, Dino Viehland began work on a patch to allow for a pluggable interface to a JIT (Just In Time) compiler. His employer, Microsoft, decided to sponsor his efforts and the result is the Pyjion project. In this episode we spoke with Dino Viehland and Brett Cannon about the goals of the project, the progress they have made so far, and the issues they have encountered along the way. We also made an interesting detour to discuss the general state of performance in the Python ecosystem and why the GIL isn't the bogeyman it's made out to be.

  • Given that this is a Microsoft backed project it makes sense that the first JIT engine to be implemented is for the CoreCLR. What would an alternative implementation provide and in what ways can a JIT framework be tuned for particular workloads? - Tobias
  • What kinds of use cases and problem domains that were previously impractical will be enabled by this? - Tobias
  • Does Microsoft's recent acquisition of Xamarin and the Mono project change things for the Pyjion project at all? - Chris
  • What are the challenges associated with your work on Pyjion? Are there certain aspects of the Python language and the CPython implementation that make the work more difficult than it might be otherwise? - Tobias
  • When I think of Microsoft and programming languages I generally think of C++ and C#. Did your team have to go through an approval process in order to utilize Python, and further to open source your work on Pyjion? - Chris
  • How does Pyjion hook into the CPython runtime and what kinds of primitives does it expose to JIT engines for them to be able to work with? - Tobias
  • Would an entire project be run through the JIT engine during runtime or is it possible to target a subset of the code being executed? - Tobias
  • In what ways can a JIT compiler implementation be purpose-built for a given workload and how would someone go about creating one? - Tobias
  • Could a JIT plugin be designed with different trade-offs, like no C API compatibility, but that worked around the GIL to provide real concurrency in Python? - Chris
  • One of the most notable benefits of having a JIT implementation for the CPython runtime is the fact that modules with C extensions can be used, such as NumPy. Does that pose any difficulties in the compilation methods used for optimizing the Python portion of the code? - Tobias
  • What kinds of performance improvements have you seen in your experimentation? - Tobias
  • Which release of Python do you hope to have Pyjion incorporated into? - Tobias
  • Has any thought been given to making Python a first class citizen in Visual Studio Code? - Chris
  • What areas of the project could use some help from our listeners? - Chris

Episode 50 - Transcrypt with Jacques de Hooge

Visit our site to listen to past episodes, support the show, join our community, and sign up for our mailing list.

Summary

Any programmer who has dealt with a website for any length of time knows that writing JavaScript isn't always the most enjoyable. Wouldn't you rather write that code in Python and just have it work on your website? In this episode we learn about Transcrypt with its creator Jacques de Hooge. Transcrypt is a Python to JavaScript transpiler that embraces the JavaScript ecosystem while letting you use the familiar syntax of Python for writing your logic, rather than trying to shoehorn a Python runtime into your browser.

Interview with Jacques de Hooge

  • Introductions
  • How did you get introduced to Python? - Tobias
  • What is Transcrypt and what inspired you to create it? - Tobias
  • As you mention in the documentation, there are a number of projects that attempt to shoehorn Python into the browser. What makes Transcrypt different? - Tobias
  • I like that you decided to embrace the web environment by calling into JavaScript libraries. What are some of the challenges that you encountered while creating that functionality? - Tobias
  • How is the transpilation performed and what are some of the methods that you used to get the build size as small as it is? - Tobias
  • Given the nature of JavaScripts prototypical inheritance and differences in class semantics, I imagine that adding support for multiple inheritance and reflecting the structure of Python classes must have been challenging. Can you describe that process and how you arrived at your current solution? - Tobias
  • Which aspects of the language were most difficult to translate to JavaScript? - Tobias
  • Is Transcrypt complete and stable enough to be used in production? - Tobias

Interview

  • Introductions
  • How did you get introduced to Python? - Chris
  • What is VPython and how did it get started? - Tobias
  • What problems inspired you to create VPython? - Chris
  • How do you design an API that allows for such powerful 3D visualization while still making it accessible to students who are focusing on learning new concepts in mathematics and physics so that they don't get overwhelmed by the tool? - Tobias
  • I know many schools have embraced the open curriculum idea, have any of your physics courses using VPython been made available to the non matriculating public? - Chris
  • How does VPython perform its rendering? If you were to reimplement it would you do anything differently? - Tobias
  • One of the remarkable points about VPython is its ability to execute the simulations in a browser environment. Can you explain the technologies involved to make that work? - Tobias
  • Given the real-time rendering capabilities in VPython I'm sure that performance is a core concern for the project. What are some of the methods that are used to ensure an appropriate level of speed and does the cross-platform nature of the package pose any additional challenges? - Tobias
  • How does collision detection work in VPython, and does it handle more complex assemblies of component objects? - Chris
  • Can you talk a little bit about VPython's design, and perhaps walk us through how a simple scene is rendered, say the results of the sphere() call? - Chris
