    The State of Security in Elixir with Holden Oullette

    In the Elixir Wizards season 15 premiere, host Charles Suggs is joined by Holden Oullette, Senior Security Software Engineer at Netflix and maintainer of Sobelow, to talk about how security is evolving in the Elixir ecosystem. We discuss how certain features of the Elixir programming language (like functional patterns and server-side rendering) provide natural immunity against some common vulnerabilities, and what that means as the language continues to grow. Holden shares how tools like Sobelow are adapting and how new technologies like LLMs and Elixir's type system may help to strengthen security practices. We cover supply chain risks, ecosystem-level responsibility and reputation management, and how initiatives like AEGIS are prepping the community for more widespread adoption. We wrap with practical tips for teams to be more security-minded throughout the software development lifecycle without slowing everything down. Key topics discussed in this episode: How Elixir’s design influences secure-by-default development Security tradeoffs between server-side and client-heavy architecture Supply chain risks and what the ecosystem is doing to prepare Static analysis with tools like Sobelow and AST-based pattern matching Where LLMs fit into modern security workflows The role of Elixir’s upcoming type system in improving tooling Securing CI/CD pipelines and production environments Balancing development speed with security requirements Dependency management and vulnerability monitoring The AEGIS Initiative and ecosystem-wide security efforts Links mentioned: Holden’s GitHub https://github.com/houllette Elixir Programming Language https://elixir-lang.org/ Security-focused static analysis for the Phoenix Framework https://github.com/nccgroup/sobelow Code Security for Builders https://semgrep.dev/ Erlang Ecosystems Foundation https://erlef.org/ Phoenix Framework https://www.phoenixframework.org/ WebSockets https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.Socket.html https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API Open Worldwide Application Security Project https://owasp.org/ https://github.com/elixir-ecto/ecto Log4j Vulnerability https://www.ncsc.gov.uk/information/log4j-vulnerability-what-everyone-needs-to-know React2Shell Vulnerability https://www.finra.org/guidance/guidance/cybersecurity-advisory-react2shell The Heartbleed Bug https://www.heartbleed.com/ Elixir Type System https://hexdocs.pm/elixir/main/gradual-set-theoretic-types.html Holden Oullette “Securing the Future: A Roadmap to Making Elixir the Safest Language” ElixirConf 2024 https://youtu.be/gpvKxS6sY8Y Aegis Initiative: Supply Chain Security & Compliance Initiative https://security.erlef.org/aegis/ OIDC Tokens https://openid.net/ Anthropic’s Claude Mythos & Cybersecurity https://red.anthropic.com/2026/mythos-preview/ Igniter Code Generation Framework https://github.com/ash-project/igniter https://smartlogic.io/podcast/elixir-wizards/s13-e01-igniter-code-generation-zach-daniel/ Secure-by-default open source software https://www.chainguard.dev/ https://www.docker.com/ https://github.com/dependabot https://docs.aws.amazon.com/apigatewayv2/latest/api-reference/apis-apiid-models.html https://nixos.org/ https://smartlogic.io/podcast/elixir-wizards/s14-e08-nix-for-elixir-apps/ https://fedoraproject.org/ https://kubernetes.io/ https://netflix.github.io/chaosmonkey/ https://netflixtechblog.com/all?topic=chaos-monkey Special Guest: Holden Oullette.

    Python in Elixir Apps with Victor Björklund

    In this episode, Elixir Wizard Charles Suggs sits down with Victor Björklund to map out the landscape of Python integration in Elixir applications. From HTTP APIs and external services to embedded runtimes like ErlPort, PythonX, and the Venomous library, we evaluate each approach’s impact on performance, coupling, and developer experience. Victor draws on real-world examples like Scrapy-based web scraping and the Swedish BankID authentication to illustrate best practices for error handling, process pooling, and effective telemetry across the BEAM boundary. We also tackle the practical side of deployment: packaging Python dependencies in Mix releases, mocking Python calls in tests, and deploying multi-language apps with confidence. Wrapping up, Victor shares his wishlist for even tighter interop (think multiple Python interpreter instances per VM) and offers low-risk entry points, like automating monthly reports, for teams ready to explore the power of Python’s ecosystem within Elixir. Key topics discussed in this episode: Integration methods: HTTP APIs, ports, ErlPort, PythonX, Venomous Performance vs. coupling trade-offs across interop patterns Managing the Global Interpreter Lock (GIL) with process pools Leveraging mature Python libraries (Scrapy, BankID, etc.) Error handling strategies across BEAM↔Python boundaries Testing mixed-language systems: mocks and integration tests Packaging and deploying Python alongside Elixir releases Monitoring and telemetry for multi-language pipelines Functional programming advantages in Elixir workflows Tool selection guidance by project requirements Future possibilities: multiple Python interpreters in one VM Community resources for Python–Elixir interop help Links mentioned: jawdropping.io https://cplusplus.com/ https://www.python.org/ https://react.dev/ https://nodejs.org/en https://erlport.org/ https://hexdocs.pm/pythonx/Pythonx.html https://pyrlang.github.io/Pyrlang/ Python GIL (Global Interpreter Lock): https://realpython.com/python-gil/ https://github.com/devinus/poolboy https://hexdocs.pm/venomous/Venomous.html Try-catch https://syntaxdb.com/ref/python/try-catch https://www.scrapy.org/ https://www.bankid.com/en/ https://www.phoenixframework.org/ https://www.tzeyiing.com/posts/using-a-hunky-poolboy-to-manage-your-python-erlport-processes-in-elixir/ https://medium.com/stuart-engineering/how-we-use-python-within-elixir-486eb4d266f9 https://x.com/bjorklundvictor https://victorbjorklund.com/ https://www.linkedin.com/in/victorbjorklund/ hello@victorbjorklund.com

    Explorer: Data Frames in Elixir with Chris Grainger

    In this episode of Elixir Wizards, Charles Suggs sits down with Chris Grainger, co-founder and CTO of Amplified and creator of the Explorer library. Chris explains how Explorer brings the familiar data-frame workflows of R’s dplyr and Python’s pandas into the Elixir world. We explore (pun intended!) how Explorer integrates with Ecto, Nx, and LiveView to build end-to-end data pipelines without leaving the BEAM, and how features like lazy evaluation and distributed frames let you tackle large datasets. Whether you’re generating reports or driving interactive charts in LiveView, Explorer makes tabular data accessible to every Elixir developer. We wrap up by looking ahead to SQL-style backends, ADBC connectivity, and other features on the Explorer roadmap. Key topics discussed in this episode: dplyr- and pandas-inspired data manipulation in Elixir Polars integration via Rust NIFs for blazing performance Immutable data frames and BEAM-friendly concurrency Lazy evaluation to work with arbitrarily large tables Distributed data-frame support for multi-node processing Seamless integration with Ecto schemas and queries Zero-copy interoperability between Explorer and Nx tensors Apache Arrow and ADBC protocols for cross-language I/O Exploring SQL-style backends for remote query execution Building interactive dashboards and charts in LiveView Consolidating ETL workflows into a single Elixir API Streaming data pipelines for memory-efficient processing Tidy data principles and behavior-based API design Real-world use cases: report generation, patent analysis, and more Future roadmap: new backends, query optimizations, and community plugins Links mentioned: https://hexdocs.pm/explorer/Explorer.html https://www.amplified.ai/ https://www.r-project.org/ https://vita.had.co.nz/papers/tidy-data.pdf https://www.tidyverse.org/ https://www.python.org/ https://dplyr.tidyverse.org/ https://go.dev/ https://hexdocs.pm/nx/Nx.html https://github.com/pola-rs/polars https://github.com/rusterlium/rustler https://www.rust-lang.org/ https://www.postgresql.org/ https://hexdocs.pm/ecto/Ecto.html https://www.elastic.co/elasticsearch https://arrow.apache.org/ Chris Grainger & Chris McCord Keynote ElixirConf 2024: https://youtu.be/4qoHPh0obv0 https://dbplyr.tidyverse.org/ https://spark.posit.co/ https://hexdocs.pm/pythonx/Pythonx.html https://hexdocs.pm/vega_lite/VegaLite.html 10 Minutes to Explorer: https://hexdocs.pm/explorer/exploring_explorer.html https://github.com/elixir-nx/scholar https://scikit-learn.org/stable/ https://github.com/cigrainger https://erlef.org/slack-invite/erlef https://bsky.app/profile/cigrainger.bsky.social https://github.com/cigrainger
