Lecturer

Deb Nicholson is the Executive Director of the Python Software Foundation. She joined the organization in April 2022 after prior roles at the Open Source Initiative (Interim General Manager), Software Freedom Conservancy (Director of Community Operations), and the Open Invention Network. A founding organizer of the Seattle GNU/Linux Conference, she has received the O’Reilly Open Source Award and the Award for the Advancement of Free Software. Nicholson resides in Cambridge, Massachusetts. Her professional profile is available on LinkedIn at https://www.linkedin.com/in/denicholson and on X under the handle @baconandcoconut.

Abstract

This multi-part welcome session presents the current state of the Python Software Foundation, its infrastructure challenges, security initiatives, and community programs, interwoven with short addresses from major sponsors. Deb Nicholson surveys growth metrics for PyPI, the grants program, staffing, and fiscal sponsorships while reflecting on the social strengths and external pressures facing the community. Accompanying remarks from representatives of AWS, Alpha Omega, Meta, and Google highlight collaborative investments in security, tooling, and language evolution.

Security Initiatives and Infrastructure Stewardship

The session opened with brief sponsor remarks. An NVIDIA representative invited attendees to discussions on faster Python and smaller downloads. Hannah Aubrey of AWS Open Source then framed the company’s commitment to long-term security of critical open-source projects, noting that AWS depends on Python’s reliability. Michael Windsor of Alpha Omega described the organization’s four-pronged approach—staffing dedicated security roles, improving package managers, conducting audits, and funding experiments—initiated in response to supply-chain crises such as Log4Shell. He credited Seth Larson and Mike Fiedler for leadership within the Python ecosystem.

Seth Larson, Security Developer in Residence at the PSF, outlined the contemporary threat landscape: vulnerability exploitation, package poisoning, and social-engineering attacks on maintainers. His mandate is to establish secure-by-default experiences for millions of users. He displayed a visualization of social relationships among top PyPI packages, underscoring that security work is distributed across a dense contributor network rather than concentrated in a single office. Larson invited participation in security-focused talks, open spaces, and a meet-the-experts session at the AWS booth later that day.

Ian Barber of Meta, a visionary sponsor, reported that Python is now the most-used language inside the company, with more than three thousand developers. Meta’s investments include Pyfly, an IDE plugin and type-check engine released in alpha for instant autocomplete and navigation on large codebases; free-threaded Python aimed at true multi-threading without the GIL, particularly beneficial for AI workloads; and continued development of Triton and PyTorch, the latter now supporting NVIDIA’s Blackwell architecture and flex attention. Barber directed attendees to the typing summit and the Meta booth.

Deb Nicholson then assumed the podium. She restated the PSF mission: to promote, protect, and advance the Python language and to foster a diverse international community. The Foundation serves as the nonprofit home for both the language and its community, providing infrastructure, security, and legal support while channeling grants and fiscal sponsorships. Python’s ascent to the most-popular language on GitHub was noted with measured pride, accompanied by gratitude to Fastly for a five-year commitment that underpins CDN capacity.

PyPI growth figures illustrated the scale of demand: an 84 percent rise in download counts and 48 percent rise in bandwidth in 2024, following 57 percent and 45 percent increases in the two preceding years. The newly launched PyPI Organizations feature, intended to support collaborative teams and to generate modest administrative revenue for further improvements, attracted 8 500 initial requests—many duplicates or low-quality. Maria Asha cleared the resulting backlog, and the feature is now fully operational under the stewardship of infrastructure lead E.

The grants program has undergone substantial redesign under Community Communications Manager Marie Nordon. Application processes are shorter, more transparent, and more equitable; community updates are regular. Demand has expanded in every dimension—events, amounts, and geographic reach—while revenue has not kept pace, prompting an open invitation for new funding ideas and corporate partnerships.

Community Resilience, Staffing, and Forward Outlook

Nicholson turned to the social character of the Python community, describing its historic openness to “weird kids” and unconventional projects—ranging from analysis of pre-Columbian tooth enamel to experimental tooling. This receptivity, she argued, keeps the language fresh and expands its application domains. Yet she acknowledged the broader context of geopolitical and economic uncertainty that has deterred hundreds of potential international attendees and complicated nonprofit operations. Layoffs, regulatory flux, and funding volatility place additional strain on a small organization whose largest single budget item remains PyCon US itself.

Despite these pressures, the human infrastructure of the PSF remains robust. Nicholson introduced the approximately thirteen staff members who support more than eight million users worldwide. Olivia Sauls directs the conference; Seth Larson and Mike Fiedler manage security reporting and infrastructure; E oversees core systems with assistance from Jacob Coffee; Marie Nordon handles grants, D&I, fellows, and communications; Jamie has transitioned from contractor to full-time events staff; accountants Phyllis and Laura manage fiscal sponsorships, payroll, and compliance; and Lauren has been promoted to Deputy Executive Director with expanded responsibilities for partnerships and strategic planning. Three CPython Developer-in-Residence positions—Lucas, Peter, and Siri—support core development, with Wukush also present for the language summit.

The Board of Directors and a suite of volunteer working groups (code of conduct, diversity and inclusion, education and outreach, fellows, grants, infrastructure, jobs board, packaging, trademarks) extend capacity further. The Foundation acts as fiscal sponsor for twenty projects, most prominently the global PyLadies network. Thousands of additional volunteers worldwide organize local conferences, meetups, and educational programs that sustain Python’s growth.

Sponsor advocacy received special thanks: the individuals inside corporations who repeatedly champion larger contributions and greater conference attendance. Nicholson closed by urging the community to “stay weird and keep welcoming all the nice weirdos,” then introduced Lisa of Google. Lisa, attending her first PyCon, praised the energy and the dedicated newcomers’ session. She reaffirmed Google’s reliance on Python across scripting, DevOps, and machine learning, and expressed particular interest in free-threaded Python, typing-standard evolution, and performance work. Multiple Google colleagues were present for the typing summit, a talk on programming for oneself, and a supply-chain security open space.

Collectively the addresses portray a Foundation that has scaled its technical and social infrastructure in step with extraordinary adoption while remaining attentive to inclusion, security, and long-term sustainability. The interplay of staff, volunteers, sponsors, and core developers illustrated in the session constitutes the operational backbone that enables the language’s continued vitality.

This approach allows operators to manage infrastructure efficiently, freeing researchers from administrative burdens.

Zenith, an innovative application proxy, enables secure external access to applications without public IPs, using SSH tunneling and OIDC authentication. Azimuth, a self-service web portal, offers pre-configured appliances like JupyterHub and Slurm clusters, customizable via Helm charts. Keycloak integration ensures secure access management, allowing platform administrators to create user accounts without granting cloud access. This architecture empowers researchers to deploy and manage platforms independently, aligning complexity with their expertise.

Case Studies: Real-World Impact

Scott presented two case studies illustrating the LOKI stack’s versatility. The first involved deploying JupyterHub for training courses on a private OpenStack cloud. Using Azimuth, administrators created isolated Keycloak realms to manage attendee accounts, ensuring secure access via Zenith’s proxying. This setup allowed course tutors to focus on teaching, with attendees accessing familiar JupyterHub environments without needing cloud credentials. The solution’s simplicity and security made it ideal for educational settings.

The second case study addressed a university’s request for a privacy-preserving large language model (LLM) service. StackHPC developed a Helm chart to deploy open-source LLMs, integrated with Azimuth for ad-hoc testing and ArgoCD for production-grade management. The service, designed to be GDPR-compliant, provided an anonymous interface for staff and students to experiment with LLMs. Monitoring via Prometheus and Grafana ensured reliability, demonstrating how StackHPC’s stack adapts to emerging technologies while maintaining robustness.

Empowering Researchers Through Simplicity

The core takeaway from Scott and Tyler’s talk was that scientists prioritize research over infrastructure management. By offering a platform that balances infrastructure-as-a-service flexibility with platform-as-a-service simplicity, StackHPC empowers researchers to work efficiently. Their commitment to open-source, evidenced by plans to donate Zenith and Azimuth to the CNCF sandbox, underscores their dedication to community-driven innovation. The LOKI stack’s ability to abstract complexity while preserving functionality positions it as a transformative tool for scientific computing.

PostHeaderIcon [NodeCongress2021] Instrumenting Node.js Internals – Alejandro Oviedo

Delving into the intricacies of runtime diagnostics reveals a persistent challenge for Node.js developers: unraveling opaque behaviors in live applications without invasive alterations. Alejandro Oviedo, a backend specialist from Buenos Aires, confronts this head-on by unveiling “instrument,” an open-source utility he crafted to illuminate network flows, filesystem interactions, and module loadings. This innovation stems from his encounters with elusive glitches, where conventional logging falls short, compelling a quest for non-disruptive observability.

Alejandro’s journey underscores a universal frustration—debugging sans exceptions or traces leaves one adrift, akin to navigating fog-shrouded waters. Even in controlled dev setups, grasping async invocations or dependency chains demands more than intuition. His tool intervenes subtly, wrapping native modules like HTTP, HTTPS, or FS to log invocations without reshaping source code, thus preserving original outputs while appending diagnostic summaries.

Enhancing Visibility Through Modular Wrappers

At the heart of instrument lies a configuration-driven approach, where users specify modules in an instrument.config.js file—HTTP for endpoint reconnaissance, REQUIRE for dynamic imports. Alejandro demonstrates with npm’s version query: invoking via instrument yields the anticipated 8.2.1 for Mocha, trailed by a concise report on GET requests to registry.npmjs.org, complete with user-agent headers and CI flags. This granularity exposes externalities, from URL patterns to payload details, sans performance penalties in non-prod realms.

Extending to refactoring scenarios, imagine auditing dynamic loads in an HTTP server; static analyzers falter against runtime evaluations, but instrument excels, flagging module_a.js imports across probes. Alejandro stresses its dev-centric ethos: add as a devDependency, execute with npx instrument node app.js, and harvest insights effortlessly. Caveats abound—overhead precludes prod use, and nascent bugs invite community scrutiny via GitHub.

Yet, this simplicity belies profound utility. By demystifying internals, developers sidestep trial-and-error marathons, accelerating triage from hours to moments. Alejandro’s creation not only empowers solo coders but fosters collaborative ecosystems, where shared configs standardize diagnostics across teams. In an era of sprawling Node.js deployments, such tools bridge the observability chasm, ensuring applications hum reliably under scrutiny.

Fostering Community-Driven Refinements

Alejandro invites scrutiny, urging PRs and issues on the repository, while teasing a Q&A for deeper dives. His Buenos Aires roots and international contributions—local meetups to global forums—infuse the project with grassroots vigor, mirroring Node.js’s collaborative spirit. As environments evolve, instrument’s extensibility promises adaptations, perhaps integrating with APMs for holistic tracing.

Through this lens, troubleshooting morphs from art to science, equipping practitioners to dissect and mend with precision. Alejandro’s endeavor reminds us: true resilience blooms from visibility, not obscurity.

PostHeaderIcon [DevoxxFR2014] Git-Deliver: Streamlining Deployment Beyond Java Ecosystems

Lecturer

Arnaud Bétrémieux is a passionate developer with 18 years of experience, including 8 professionally, specializing in open-source technologies, GNU/Linux, and languages like Java, PHP, and Lisp. He works at Key Consulting, providing development, hosting, consulting, and expertise services. Sylvain Veyrié, with nearly a decade in Java platforms, serves as Director of Delivery at Transparency Rights Management, focusing on big data, and has held roles in development, project management, and training at Key Consulting.

Abstract

This article investigates git-deliver, a deployment tool leveraging Git’s integrity guarantees for simple, traceable, and atomic deployments across diverse languages. It dissects the tool’s mechanics, from remote setup to rollback features, and discusses customization via scripts and presets, emphasizing its role in replacing ad-hoc scripts in dynamic language projects.

Core Principles and Setup

Git-deliver emerges as a Bash script extending Git with a “deliver” subcommand, aiming for simplicity, reliability, efficiency, and universality in deployments. Targeting non-Java environments like Node.js, PHP, or Rails, it addresses the pitfalls of custom scripts that introduce risks in traceability and atomicity.

A deployment target equates to a Git remote over SSH. For instance, creating remotes for test and production environments involves commands like git remote add test deliver@test.example.fr:/appli and git remote add prod deliver@example.fr:/appli. Deliveries invoke git deliver <remote> <version>, where version can be a branch, commit SHA, or tag.

On the target server, git-deliver initializes a bare Git repository alongside a “delivered” directory containing clones for each deployment. Each clone includes Git metadata and a working copy checked out to the specified version. Symbolic links, particularly “current,” point to the latest clone, ensuring a fixed path for applications and atomic switches— the link updates instantaneously, avoiding partial states.

Directory names incorporate timestamps and abbreviated SHAs, facilitating quick identification of deployed versions. This structure preserves history, enabling audits and rollbacks.

Information Retrieval and Rollback Mechanisms

To monitor deployments, git-deliver offers a “status” option. Without arguments, it surveys all remotes, reporting the current commit SHA, tag if applicable, deployment timestamp, and deployer. It also verifies integrity, alerting to uncommitted changes that might indicate manual tampering.

Specifying a remote yields a detailed history of all deliveries, including directory identifiers. Additionally, git-deliver auto-tags each deployment in the local repository, annotating with execution logs and optional messages. Pushing these tags to a central repository shares deployment history team-wide.

Rollback supports recovery: git deliver rollback <remote> reverts to the previous version by updating the “current” symlink to the prior clone. For specific versions, provide the directory name. This leverages preserved clones, ensuring exact restoration even if files were altered post-deployment.

Customization and Extensibility

Deployments divide into stages (e.g., init-remote for first-time setup, post-symlink for post-switch actions), allowing user-provided scripts executed at each. For normal deliveries, scripts might install dependencies or migrate databases; for rollbacks, they handle reversals like database adjustments.

To foster reusability, git-deliver introduces “presets”—collections of stage scripts for frameworks like Rails or Flask. Dependencies between presets (e.g., Rails depending on Ruby) enable modular composition. The “init” command copies preset scripts into a .deliver directory at the project root, customizable and versionable via Git.

This extensibility accommodates varied workflows, such as compiling sources on-server for compiled languages, though git-deliver primarily suits interpreted ones.

Broader Impact on Deployment Practices

By harnessing Git’s push mechanics and integrity checks, git-deliver minimizes errors from manual interventions, ensuring deployments are reproducible and auditable. Its atomic nature prevents service disruptions, crucial for production environments.

While not yet supporting distributed deployments natively, scripts can orchestrate multi-server coordination. Future enhancements might incorporate remote groups for parallel pushes.

In production at Key Consulting, git-deliver demonstrates maturity beyond prototyping, offering a lightweight alternative to complex tools, promoting standardized practices across projects.
