[NDCMelbourne2025] How to Work with Generative AI in JavaScript – Phil Nash
Phil Nash, a developer relations engineer at DataStax, delivers a comprehensive guide to leveraging generative AI in JavaScript at NDC Melbourne 2025. His talk demystifies the process of building AI-powered applications, emphasizing that JavaScript developers can harness existing skills to create sophisticated solutions without needing deep machine learning expertise. Through practical examples and insights into tools like Gemini and retrieval-augmented generation (RAG), Phil empowers developers to explore this rapidly evolving field.
Understanding Generative AI Fundamentals
Phil begins by addressing the excitement surrounding generative AI, noting its accessibility since the release of the GPT-3.5 API two years ago. He emphasizes that JavaScript developers are well-positioned to engage with AI due to robust tooling and APIs, despite the field’s Python-centric origins. Using Google’s Gemini model as an example, Phil demonstrates how to generate content with minimal code, highlighting the importance of understanding core concepts like token generation and model behavior.
He explains tokenization, using OpenAI’s byte pair encoding as an example, where text is broken into probabilistic tokens. Parameters like top-k, top-p, and temperature allow developers to control output randomness, with Phil cautioning against overly high settings that produce nonsensical results, humorously illustrated by a chaotic AI-generated story about a gnome.
Enhancing AI with Prompt Engineering
Prompt engineering emerges as a critical skill for refining AI outputs. Phil contrasts zero-shot prompting, which offers minimal context, with techniques like providing examples or system prompts to guide model behavior. For instance, a system prompt defining a “capital city assistant” ensures concise, accurate responses. He also explores chain-of-thought prompting, where instructing the model to think step-by-step improves its ability to solve complex problems, such as a modified river-crossing riddle.
Phil underscores the need for evaluation to ensure prompt reliability, as slight changes can significantly alter outcomes. This structured approach transforms prompt engineering from guesswork into a disciplined practice, enabling developers to tailor AI responses effectively.
Retrieval-Augmented Generation for Contextual Awareness
To address AI models’ limitations, such as outdated or private data, Phil introduces retrieval-augmented generation (RAG). RAG enhances models by integrating external data, like conference talk descriptions, into prompts. He explains how vector embeddings—multidimensional representations of text—enable semantic searches, using cosine similarity to find relevant content. With DataStax’s Astra DB, developers can store and query vectorized data efficiently, as demonstrated in a demo where Phil’s bot retrieves details about NDC Melbourne talks.
This approach allows AI to provide contextually relevant answers, such as identifying AI-related talks or conference events, making it a powerful tool for building intelligent applications.
Streaming Responses and Building Agents
Phil highlights the importance of user experience, noting that AI responses can be slow. Streaming, supported by APIs like Gemini’s generateContentStream, delivers tokens incrementally, improving perceived performance. He demonstrates streaming results to a webpage using JavaScript’s fetch and text decoder streams, showcasing how to create responsive front-end experiences.
The talk culminates with AI agents, which Phil describes as systems that perceive, reason, plan, and act using tools. By defining functions in JSON schema, developers can enable models to perform tasks like arithmetic or fetching web content. A demo bot uses tools to troubleshoot a keyboard issue and query GitHub, illustrating agents’ potential to solve complex problems dynamically.
Conclusion: Empowering JavaScript Developers
Phil concludes by encouraging developers to experiment with generative AI, leveraging tools like Langflow for visual prototyping and exploring browser-based models like Gemini Nano. His talk is a call to action, urging JavaScript developers to build innovative applications by combining AI capabilities with their existing expertise. By mastering prompt engineering, RAG, streaming, and agents, developers can create powerful, user-centric solutions.

[NDCMelbourne2025] Preventing Emu Wars with Domain-Driven Design – Lee Dunkley
In an engaging and humorous presentation at NDC Melbourne 2025, Lee Dunkley explores how Domain-Driven Design (DDD) can prevent software projects from spiraling into chaotic, unmaintainable codebases—likening such failures to Australia’s infamous Emu War. By drawing parallels between historical missteps and common software development pitfalls, Lee illustrates how DDD practices, such as event storming and ubiquitous language, can steer teams toward solving the right problems, thereby enhancing maintainability and extensibility.
The Emu War: A Cautionary Tale for Coders
Lee begins with a whimsical analogy, recounting Australia’s 1930s Emu War, where soldiers armed with machine guns failed to curb an overwhelming emu population devastating crops. The emus’ agility and sheer numbers outmatched the military’s efforts, leading to a humbling defeat. Lee cleverly translates this to software development, where throwing endless code at a problem—akin to deploying infinite soldiers—often results in a complex, bug-ridden system. This sets the stage for his argument: without proper problem definition, developers risk creating their own unmanageable “emu wars.”
He illustrates this with a hypothetical coding scenario where a client demands a solution to “kill all the pesky emus.” Developers might churn out classes and methods, only to face mounting complexity and bugs, such as emus “upgrading to T-Rexes.” The lesson? Simply writing more code doesn’t address the root issue, much like the Emu War’s flawed strategy failed to protect farmers’ crops.
Modeling Smells in E-Commerce
Transitioning to a more practical domain, Lee applies the Emu War analogy to an e-commerce platform tasked with implementing an “update order” feature. Initially, the solution seems straightforward: create an endpoint to modify orders. However, as Lee demonstrates, this leads to bugs like customers receiving too many items, being undercharged, or getting empty boxes. These issues arise because the vague “update order” requirement invites a cascade of edge cases and race conditions.
By examining the system’s event timeline, Lee highlights how an “order updated” event disrupts critical processes like payment capture and stock reservation. This modeling smell—where a generic action undermines system integrity—mirrors the Emu War’s misaligned objectives. The real problem, Lee argues, lies in failing to define the business’s true needs, resulting in a codebase that’s hard to test and extend.
Refining with Domain-Driven Design
Here, Lee introduces DDD as a remedy, emphasizing techniques like event storming and the five whys to uncover the true problem space. Revisiting the Emu War, he applies the five whys to reveal that the goal wasn’t to kill emus but to secure employment for returning soldiers. Similarly, in the e-commerce case, the “update order” request masks specific needs: ensuring shoppers receive only desired items, adding forgotten items, and canceling orders.
By reframing these needs, Lee proposes targeted solutions, such as a “supplementary order” endpoint for adding items and a time-bound “order received” event to allow cancellations without disrupting the system. These solutions, rooted in DDD’s ubiquitous language, reduce complexity by aligning the code with business intent, avoiding the pitfalls of generic actions like “update.”
Simplicity Through Abstraction
Lee challenges the notion that complex problems demand complex solutions. Through DDD, he shows how elevating the level of abstraction—by focusing on precise business goals—eliminates unnecessary complexity. In the e-commerce example, replacing the problematic “update order” endpoint with simpler, purpose-specific endpoints demonstrates how DDD fosters maintainable, extensible code.
He acknowledges the challenges of implementing such changes in live systems, where breaking changes can be daunting. However, Lee argues that aligning solutions with the problem space is worth the effort, as it prevents the codebase from becoming a “Frankenstein’s monster” burdened by accidental complexity.
Conclusion: Avoiding Your Own Emu War
Lee wraps up by urging developers to wield their coding “superpower” wisely. Instead of burying problems under an avalanche of code, he advocates for DDD practices to ensure solutions reflect the business’s true needs. By employing event storming, refining ubiquitous language, and questioning requirements with the five whys, developers can avoid fighting futile, unmaintainable battles.
This talk serves as a compelling reminder that thoughtful problem definition is the cornerstone of effective software development. Lee’s blend of humor and practical insights makes a strong case for embracing DDD to create robust, adaptable systems.

[NDCMelbourne2025] A Look At Modern Web APIs You Might Not Know – Julian Burr
As web technologies evolve, the capabilities of browsers have expanded far beyond their traditional roles, often rendering the need for native applications obsolete for certain functionalities. Julian Burr, a front-end engineer with a passion for design systems, delivers an engaging exploration of modern web APIs at NDC Melbourne 2025. Through his demo application, stopme.io—a stopwatch-as-a-service platform—Julian showcases how these APIs can enhance user experiences while adhering to the principle of progressive enhancement. His talk illuminates the power of web APIs to bridge the gap between web and native app experiences, offering practical insights for developers.
The Philosophy of Progressive Enhancement
Julian begins by championing progressive enhancement, a design philosophy that ensures baseline functionality for all users while delivering enhanced experiences for those with modern browsers. Quoting Mozilla, he defines it as providing essential content to as many users as possible while optimizing for advanced environments. This approach is critical when integrating web APIs, as it prevents over-reliance on features that may not be universally supported. For instance, in stopme.io, Julian ensures core stopwatch functionality remains accessible, with APIs adding value only when available. This philosophy guides his exploration, ensuring inclusivity and robustness in application design.
Observing the Web: Resize and Intersection Observers
The first category Julian explores is observability APIs, starting with the Resize Observer and Intersection Observer. These APIs, widely supported, allow developers to monitor changes in DOM element sizes and visibility within the viewport. In stopme.io, Julian uses the Intersection Observer to load JavaScript chunks only when components become visible, optimizing performance. While CSS container queries address styling needs, these APIs enable dynamic behavioral changes, making them invaluable for frameworks like Astro that rely on code splitting. Julian emphasizes their relevance, as they underpin many modern front-end optimizations, enhancing user experience without compromising accessibility.
Enhancing User Context: Network and Battery Status
Julian then delves into APIs that provide contextual awareness, such as the Page Visibility API, Network Information API, and Battery Status API. The Page Visibility API allows stopme.io to update the browser title bar with the timer status when the tab is inactive, enabling users to multitask. The Network Information API offers insights into connection types, allowing developers to serve lower-resolution assets on cellular networks. Similarly, the Battery Status API warns users of potential disruptions due to low battery, as demonstrated when stopme.io alerts users about long-running timers. Julian cautions about fingerprinting risks, noting that browser vendors intentionally reduce accuracy to protect privacy, aligning with progressive enhancement principles.
Elevating Components: Screen Wake Lock and Vibration
Moving to component enhancement, Julian highlights the Screen Wake Lock and Vibration APIs. The Screen Wake Lock API prevents devices from entering sleep mode during critical tasks, such as keeping stopme.io’s timer visible. The Vibration API adds haptic feedback, like notifying users when a timer finishes, with customizable patterns for engaging effects. Julian stresses user control, suggesting toggles to avoid intrusive experiences. While these APIs—often Chrome-centric—enhance interactivity, Julian underscores the need for fallback options to maintain functionality across browsers, ensuring no user is excluded.
Native-Like Experiences: File System, Clipboard, and Share APIs
Julian showcases APIs that rival native app capabilities, including the File System, Clipboard, and Share APIs. The File System API enables file picker interactions, while the Clipboard API facilitates seamless copy-paste operations. The Share API, used in stopme.io, triggers native sharing dialogs, simplifying content distribution across platforms. These APIs, inspired by tools like Cordova, reflect the web’s evolution toward native-like functionality. Julian notes their security mechanisms, such as transient activation for Clipboard API, which require user interaction to prevent misuse, ensuring both usability and safety.
Streamlining Authentication: Web OTP and Credential Management
Authentication APIs, such as Web OTP and Credential Management, offer seamless login experiences. The Web OTP API automates SMS-based one-time password entry, as demonstrated in stopme.io, where Chrome facilitates code sharing across devices. The Credential Management API streamlines password storage and retrieval, reducing login friction. Julian highlights their synergy with the Web Authentication API, which supports passwordless logins via biometrics. These APIs, widely available, enhance security and user convenience, making them essential for modern web applications.

[NDCOslo2024] Mirror, Mirror: LLMs and the Illusion of Humanity – Jodie Burchell
In the mesmerizing mirror maze of machine mimicry, where words weave worlds indistinguishable from wit, Jodie Burchell, JetBrains’ data science developer advocate, shatters the spell of sentience in large language models (LLMs). A PhD psychologist turned NLP pioneer, Jodie probes the psychological ploys that propel projections of personhood onto probabilistic parsers, dissecting claims from consciousness to cognition. Her inquiry, anchored in academia and augmented by anecdotes, advises acuity: LLMs as linguistic lenses, not living likenesses, harnessing their heft while heeding hallucinations.
Jodie greets with gratitude for her gritty slot, her hipster cred in pre-prompt NLP notwithstanding. LLMs’ 2022 blaze beguiles: why bestow brains on bytes when other oracles oblige? Her hypothesis: humanity’s hall of mirrors, where models mirror our mores, eliciting empathy from echoes.
Psychological Projections: Perceiving Personhood in Parsers
Humans, Jodie hazards, hallucinate humanity: anthropomorphism’s ancient artifice, from pets to puppets. LLMs lure with language’s liquidity—coherent confessions conjure companionship. She cites stochastic parrots: parleying patterns, not pondering profundities, yet plausibility persuades.
Extraordinary assertions abound: Blake Lemoine’s LaMDA “alive,” Google’s Gemini “godhead.” Jodie juxtaposes: sentience’s scaffold—selfhood, suffering—sans in silicon. Chalmers’ conundrum: consciousness connotes qualia, quanta qualms quell in qubits.
Levels of Luminescence: From Language to Luminary
DeepMind’s AGI arc: Level 1 chatbots converse convincingly; Level 2 reasons reactively; Level 3 innovates imaginatively. LLMs linger at 1-2, lacking Level 4’s abstraction or 5’s autonomy. Jodie jests: jackdaws in jester’s garb, juggling jargon sans judgment.
Illusions intensify: theory of mind’s mirage, where models “infer” intents from inferences. Yet, benchmarks belie: ARC’s abstraction stumps, BIG-bench’s breadth baffles—brilliance brittle beyond basics.
Perils of Projection: Phishing and Philosophical Pitfalls
Prompt injections prey: upstream overrides oust origins, birthing bogus bounties—”Amazon voucher via arcane URL.” Jodie demonstrates: innocuous inquiries infected, innocuousness inverted into inducements. Robustness rankles: rebuttals rebuffed, ruses reiterated.
Her remedy: recognize reflections—lossy compressions of lore, not luminous lives. Demystify to deploy: distill data, detect delusions, design defensively.
Dispelling the Delusion: Harnessing Heuristics Humanely
Jodie’s jeremiad: myths mislead, magnifying misuses—overreach in oracles, oversight in safeguards. Her horizon: LLMs as lucid lenses, amplifying analysis while acknowledging artifice.

His hour, a whirlwind of wisdom and wireframes, equips ensembles to embed Kafka as backbone, blending brokers with .NET’s breadth for robust, reactive realms.
Ian immerses immediately: Kafka, a distributed commit log, chronicles changes for consumption, contrasting queues’ ephemera. Born from LinkedIn’s logging ledger in 2011, it scaled to streams, spawning Connect for conduits and Flink for flows. Ian’s inflection: Kafka as nervous system, not notification nook—durable, disorderly, decentralized.
Unpacking the Pipeline: Kafka’s Primal Primitives
Kafka’s corpus: topics as ledgers, partitioned for parallelism, replicated for redundancy. Producers pen records—key-value payloads with headers—SerDes serializing strings or structs. Consumers cull via offsets, groups coordinating coordination, enabling elastic elasticity.
Ian illuminates inroads: Confluent’s Cloud for coddling, self-hosted for sovereignty. .NET’s ingress: Confluent.Kafka NuGet, crafting IProducer for publishes, IConsumer for pulls. His handler: await producer.ProduceAsync(topic, new Message {Key = key, Value = serialized}).
Schemas safeguard: registries register Avro or Protobuf, embedding IDs for evolution. Ian’s caveat: magic bytes mandate manual marshaling in .NET, yet compatibility curtails chaos.
Forging Flows: From Fundamentals to Flink Frontiers
Fundamentals flourish: idempotent producers preclude duplicates, transactions tether topics. Ian’s .NET nuance: transactions via BeginTransaction, committing confluences. Exactly-once semantics, once Java’s jewel, beckon .NET via Kafka Streams’ kin.
Connect catalyzes: sink sources to SQL, sources streams from files—redpanda’s kin for Kafka-less kinship. Flink forges further: stream processors paralleling data dances, yet .NET’s niche narrows to basics.
Ian’s interlude: brighter bridges, abstracting brokers for seamless swaps—Rabbit to Kafka—sans syntactic shifts.
Safeguarding Streams: Resilience and Realms
Resilience roots in replicas: in-sync sets (ISR) insure idempotence, unclean leader elections avert anarchy. Ian’s imperative: tune retention—time or tally—for traceability, not torrent.
His horizon: Kafka as canvas for CQRS, where commands commit, queries query—event sourcing’s engine.

Amy acknowledges her last-minute logistics—audio absent, yet ardor undimmed—yet plunges into profundity: technology’s ubiquity underscores urgency, as 1.2 billion with disabilities confront barriers baked into bytes. She shatters stereotypes: accessibility aids all—temporary tribulations like fractured limbs or fractured focus benefit from barrier-free builds.
Universal Usability: Beyond Barriers to Broader Benefits
Accessibility, Amy avows, amplifies agency: screen readers summon sightless surfers to seas of content, captions convey clarity amid clamor, alt text unveils visuals to the visionless. Her hierarchy of harmony: POUR principles—Perceivable, Operable, Understandable, Robust—guide guardians toward grandeur.
Amy animates with audits: color contrasts calibrated for chromatic challenges, keyboard cascades for motor maladies, semantic structures for scanner scrutiny. Overlays, she ostracizes: ostensible panaceas that exacerbate, overriding user overrides and inviting incursions.
Collective Custodianship: Crafting Change Collaboratively
Everyone, Amy emphasizes, owns obligation: developers discern deficits, designers dream diversely, managers mandate metrics. Her mosaic: small strides—semantic tags, focus indicators—sum to seismic shifts, serving seniors, multitaskers, multilinguals.
Resources ripple: her repository at capesa11y.com, a cornucopia of checklists and courses, catalyzes competence. Amy’s axiom: inaccessibility isolates, accessibility integrates—elevating equity in an equitable ether.
