Cat Morris, a product manager at Snyk, delivered a thought-provoking session at KCDUK2024, exploring the challenges of building platforms in brownfield environments. Drawing from her extensive experience in legacy modernization, Cat challenged the audience to rethink traditional approaches to platform development. Her talk, rich with insights from psychology and practical strategies, offered a roadmap for transforming existing systems into robust, user-adopted platforms, emphasizing the importance of trust, ownership, and user-centric design.

The Brownfield Reality

Cat introduced the concept of brownfield development, borrowed from civil engineering, where new projects are built amidst existing, often hazardous, structures. In software, brownfield describes developing new systems alongside legacy applications, a reality for most platform teams. Unlike greenfield projects, which start from scratch, brownfield environments inherit constraints and complexities. Cat’s experience at BT, government agencies, and Thoughtworks underscored that platforms rarely begin with a clean slate; they emerge from existing engineering teams’ workflows, making adoption a significant challenge.

Her story of a neo-bank transitioning from a crypto wallet to a regulated entity illustrated this. Initially, her team built a greenfield platform to address compliance needs, only to find that existing teams preferred their familiar, albeit imperfect, processes. This resistance led Cat to a key realization: platforms are inherently brownfield and emergent, evolving from common pain points rather than imposed solutions. Understanding this shift is critical for building platforms that resonate with users.

Psychological Barriers to Adoption

Cat leveraged psychological principles to explain user resistance. Prospect theory, from Daniel Kahneman and Amos Tversky, suggests people prefer certain outcomes over risky, potentially higher-reward alternatives. In platform development, this translates to teams sticking with familiar processes despite a new platform’s benefits. Cat advocated focusing on a “job to be done” framework, ensuring platforms enable users to complete specific tasks end-to-end, reducing perceived risk and encouraging adoption.

The endowment effect further complicates adoption, as users value their existing systems—however flawed—because they “own” them. Cat shared how pairing with a team at the neo-bank, integrating their needs into the platform, fostered a sense of ownership. This collaboration turned skeptics into advocates, driving near-100% adoption within six months. By involving users in design, platform teams can transfer this sense of ownership, making the new system feel like a natural extension of their workflow.

Building Trust for Long-Term Success

Trust, Cat emphasized, is the linchpin of platform adoption. Drawing on trust repair research, she highlighted how trust, once broken, is difficult to restore fully. A platform outage or failure can erode user confidence, requiring significant effort to rebuild. To avoid this, Cat recommended transparent roadmaps, high-quality monitoring to preempt issues, and consistent experiences through tools like fleet management. Her anecdote about her cat, Opal, illustrated this vividly: failing to reward Opal’s tricks broke trust, requiring weeks to restore, a lesson applicable to platform users.

Cat’s strategies—focusing on user outcomes, fostering ownership, and prioritizing trust—offer a blueprint for navigating brownfield challenges. By building platforms alongside users, incorporating familiar elements, and pacing changes to match user workflows, teams can overcome resistance and drive adoption. Her call to action urged platform engineers to embrace these principles, ensuring platforms are not just functional but trusted and valued by their users.

Prototype pollution is one of those vulnerabilities that many developers have heard about, but few fully understand—or guard against. It’s sneaky, dangerous, and more common than you’d think, especially in JavaScript and Node.js applications.

This post breaks down what prototype pollution is, how it can be exploited, how to detect it, and most importantly, how to fix it.

What Is Prototype Pollution?

In JavaScript, all objects inherit from Object.prototype by default. If an attacker can modify that prototype via user input, they can change how every object behaves.

This is called prototype pollution, and it can:

• Alter default behavior of native objects
• Lead to privilege escalation
• Break app logic in subtle ways
• Enable denial-of-service (DoS) or even remote code execution in some cases

Real-World Exploit Example

const payload = JSON.parse('{ "__proto__": { "isAdmin": true } }');
Object.assign({}, payload);

console.log({}.isAdmin); // → true 

Now, any object in your app believes it’s an admin. That’s the essence of prototype pollution.

How to Detect It

✅ Static Code Analysis

• ESLint
  • Use plugins like eslint-plugin-security or eslint-plugin-no-prototype-builtins
• Semgrep
  • Detect unsafe merges with custom rules

Dependency Scanning

• npm audit, yarn audit, or tools like Snyk, OWASP Dependency-Check
• Many past CVEs (e.g., Lodash < 4.17.12) were related to prototype pollution

Manual Testing

Try injecting:

{ "__proto__": { "injected": true } }

Then check if unexpected object properties appear in your app.

️ How to Fix It

1. Sanitize Inputs

Never allow user input to include dangerous keys:

• __proto__
• constructor
• prototype

2. Avoid Deep Merge with Untrusted Data

Use libraries that enforce safe merges:

• deepmerge with safe mode
• Lodash >= 4.17.12

3. Write Safe Merge Logic

function safeMerge(target, source) {
  for (let key in source) {
    if (!['__proto__', 'constructor', 'prototype'].includes(key)) {
      target[key] = source[key];
    }
  }
  return target;
}

4. Use Secure Parsers

• secure-json-parse
• @hapi/hoek

TL;DR

‍ Final Thoughts

Prototype pollution isn’t just a theoretical risk. It has appeared in real-world vulnerabilities in major libraries and frameworks.

If your app uses JavaScript—on the frontend or backend—you need to be aware of it.

Kent C. Dodds, in his dynamic 22-minute talk at Devoxx Greece 2025, explored how Model Context Protocols (MCPs) enable AI assistants to interact with applications, envisioning a future where users have their own “Jarvis” from Iron Man.

The Vision of Jarvis

Dodds opened with a clip from Iron Man, showcasing Jarvis performing tasks like compiling databases, generating UI, and creating flight plans. He posed a question: why don’t we have such assistants today? Current technologies, like Google Assistant or Siri, fall short due to limited integrations. Dodds argued that MCPs, a standard protocol supported by Anthropic, OpenAI, and Google, bridge this gap by enabling AI to communicate with diverse services, from Slack to local government platforms, transforming user interaction.

MCP Architecture

MCPs sit between the host application (e.g., ChatGPT, Claude) and service tools, allowing seamless communication. Dodds explained that LLMs generate tokens but rely on host applications to execute actions. MCP servers, managed by service providers, connect to tools, enabling users to install them like apps. In a demo, Dodds showed an MCP server for his website, allowing an AI to search blog posts and subscribe users to newsletters, though client-side issues hindered reliability, highlighting the need for improved user experiences.

Challenges and Future

The primary challenge is the poor client experience for installing MCP servers, currently requiring manual JSON configuration. Dodds predicted a marketplace or auto-discovery system to streamline this, likening MCPs to the internet’s impact. Security concerns, similar to early browsers, need addressing, but Dodds sees AI hosts as the new browsers, promising a future where personalized AI assistants handle complex tasks effortlessly.

Reusing Rust Code in Web Applications

WebAssembly (WASM) has emerged as a transformative technology for reusing backend code in web applications, offering portability and performance across platforms. At OxidizeConf2024, Georg Semmler and Jonas Klein from Giga Infosystems presented a compelling case study on leveraging Rust and WebAssembly to enhance a geological subsurface modeling system. Their project, developed for a German federal agency, involved reusing computationally intensive Rust code for generating virtual boreholes in both backend systems and a 3D web viewer, showcasing WebAssembly’s potential to bridge backend and frontend development.

The GST system, comprising a Rust-based backend, a TypeScript-based web application, and a desktop client, manages large geological models with millions of triangles. Georg and Jonas explained how the virtual borehole feature, which calculates intersections between a cylindrical probe and subsurface layers, was initially implemented in Rust for the backend. By compiling this code to WebAssembly, they enabled the same functionality in the web viewer, allowing users to validate models against real-world data in real time, a critical requirement for geological analysis.

Implementing WebAssembly Workflows

The implementation process involved several key steps, which Georg detailed with clarity. The team used the wasm32 target to compile Rust code into WebAssembly binaries, leveraging Rust’s robust tooling, including Cargo and wasm-bindgen. This library facilitated seamless integration with JavaScript, enabling type-safe communication between the Rust code and the web application. To avoid blocking the main thread, the team employed web workers and Comlink, a library that simplifies worker communication, alongside shared array buffers to minimize data copying.

Performance comparisons underscored WebAssembly’s advantages. For a small model with 300,000 triangles, the Rust-WebAssembly implementation computed intersections in 7 milliseconds, compared to 100 milliseconds for an unoptimized TypeScript version. For larger models, the performance gap widened, with WebAssembly significantly outperforming TypeScript due to its native execution speed. However, Jonas noted challenges, such as WebAssembly’s 2GB memory limit, which required careful optimization of data structures to handle large geometries.

Real-World Impact and Future Directions

The adoption of WebAssembly in the GST system has profound implications for geological applications, particularly in public communication and geothermal energy exploration. Jonas highlighted use cases like visualizing radioactive waste disposal sites and assessing subsurface potential, which benefit from the system’s ability to handle complex 3D models. The team’s success in reusing Rust code across platforms demonstrates WebAssembly’s potential to streamline development, reduce duplication, and enhance performance.

Looking forward, Georg and Jonas plan to optimize memory usage further and explore additional WebAssembly use cases, such as integrating game logic for interactive visualizations. Their work underscores the importance of community collaboration, with contributions to open-source WebAssembly tools enhancing the ecosystem. By sharing their approach, they inspire developers to leverage Rust and WebAssembly for efficient, reusable code in data-intensive applications.

Unlocking the Power of Apache Parquet: A Modern Standard for Data Efficiency

In today’s digital ecosystem, where data volume, velocity, and variety continue to rise, the choice of file format can dramatically impact performance, scalability, and cost. Whether you are an architect designing a cloud-native data platform or a developer managing analytics pipelines, Apache Parquet stands out as a foundational technology you should understand — and probably already rely on.

This article explores what Parquet is, why it matters, and how to work with it in practice — including real examples in Python, Java, Node.js, and Bash for converting and uploading files to Amazon S3.

What Is Apache Parquet?

Apache Parquet is a high-performance, open-source file format designed for efficient columnar data storage. Originally developed by Twitter and Cloudera and now an Apache Software Foundation project, Parquet is purpose-built for use with distributed data processing frameworks like Apache Spark, Hive, Impala, and Drill.

Unlike row-based formats such as CSV or JSON, Parquet organizes data by columns rather than rows. This enables powerful compression, faster retrieval of selected fields, and dramatic performance improvements for analytical queries.

Why Choose Parquet?

✅ Columnar Format = Faster Queries

Because Parquet stores values from the same column together, analytical engines can skip irrelevant data and process only what’s required — reducing I/O and boosting speed.

Compression and Storage Efficiency

Parquet achieves better compression ratios than row-based formats, thanks to the similarity of values in each column. This translates directly into reduced cloud storage costs.

Schema Evolution

Parquet supports schema evolution, enabling your datasets to grow gracefully. New fields can be added over time without breaking existing consumers.

Interoperability

The format is compatible across multiple ecosystems and languages, including Python (Pandas, PyArrow), Java (Spark, Hadoop), and even browser-based analytics tools.

☁️ Using Parquet with Amazon S3

One of the most common modern use cases for Parquet is in conjunction with Amazon S3, where it powers data lakes, ETL pipelines, and serverless analytics via services like Amazon Athena and Redshift Spectrum.

Here’s how you can write Parquet files and upload them to S3 in different environments:

From CSV to Parquet in Practice

Python Example

import pandas as pd

# Load CSV data
df = pd.read_csv("input.csv")

# Save as Parquet
df.to_parquet("output.parquet", engine="pyarrow")

To upload to S3:

import boto3

s3 = boto3.client("s3")
s3.upload_file("output.parquet", "your-bucket", "data/output.parquet")

Node.js Example

Install the required libraries:

npm install aws-sdk

Upload file to S3:

const AWS = require('aws-sdk');
const fs = require('fs');

const s3 = new AWS.S3();
const fileContent = fs.readFileSync('output.parquet');

const params = {
    Bucket: 'your-bucket',
    Key: 'data/output.parquet',
    Body: fileContent
};

s3.upload(params, (err, data) => {
    if (err) throw err;
    console.log(`File uploaded successfully at ${data.Location}`);
});

☕ Java with Apache Spark and AWS SDK

In your pom.xml, include:

<dependency>
    <groupId>org.apache.parquet</groupId>
    <artifactId>parquet-hadoop</artifactId>
    <version>1.12.2</version>
</dependency>
<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-s3</artifactId>
    <version>1.12.470</version>
</dependency>

Spark conversion:

Dataset<Row> df = spark.read().option("header", "true").csv("input.csv");
df.write().parquet("output.parquet");

Upload to S3:

AmazonS3 s3 = AmazonS3ClientBuilder.standard()
    .withRegion("us-west-2")
    .withCredentials(new AWSStaticCredentialsProvider(
        new BasicAWSCredentials("ACCESS_KEY", "SECRET_KEY")))
    .build();

s3.putObject("your-bucket", "data/output.parquet", new File("output.parquet"));

Bash with AWS CLI

aws s3 cp output.parquet s3://your-bucket/data/output.parquet

Final Thoughts

Apache Parquet has quietly become a cornerstone of the modern data stack. It powers everything from ad hoc analytics to petabyte-scale data lakes, bringing consistency and efficiency to how we store and retrieve data.

Whether you are migrating legacy pipelines, designing new AI workloads, or simply optimizing your storage bills — understanding and adopting Parquet can unlock meaningful benefits.

When used in combination with cloud platforms like AWS, the performance, scalability, and cost-efficiency of Parquet-based workflows are hard to beat.

Lecturer

Pascal Vuylsteker serves as Senior Director of Innovation at Confluent, where he spearheads advancements in scalable data streaming platforms designed to empower enterprise artificial intelligence initiatives. Mario Rodriguez operates as Senior Partner Solutions Architect at AWS, concentrating on seamless integrations of generative AI services within cloud ecosystems. Gavin Doyle heads the Applied AI team at Anthropic, directing efforts toward developing reliable, interpretable, and ethically aligned large language models.

Abstract

This comprehensive scholarly analysis investigates the foundational principles and practical methodologies for deploying real-time generative AI applications by harmonizing Confluent’s data streaming capabilities with Amazon Bedrock’s fully managed foundation model access and Anthropic’s advanced language models. The discussion centers on establishing robust data governance frameworks, implementing retrieval-augmented generation with continuous contextual updates, and leveraging Flink SQL for instantaneous inference. Through detailed architectural examinations and illustrative configurations, the article elucidates how these components dismantle data silos, ensure up-to-date relevance in AI responses, and facilitate scalable, secure innovation across organizational boundaries.

Establishing Governance-Centric Modern Data Infrastructures

Contemporary enterprise environments increasingly acknowledge the indispensable role of data streaming in fostering operational agility. Empirical insights reveal that seventy-nine percent of information technology executives consider real-time data flows essential for maintaining competitive advantage. Nevertheless, persistent obstacles—ranging from fragmented technical competencies and isolated data repositories to escalating governance complexities and heightened expectations from generative AI adoption—continue to hinder comprehensive exploitation of these potentials.

To counteract such impediments, contemporary data architectures prioritize governance as the pivotal nucleus. This core ensures that information remains secure, compliant with regulatory standards, and readily accessible to authorized stakeholders. Encircling this nucleus are interdependent elements including data warehouses for structured storage, streaming analytics for immediate processing, and generative AI applications that derive actionable intelligence. Such a holistic configuration empowers institutions to eradicate silos, achieve elastic scalability, and satisfy burgeoning demands for instantaneous insights.

Confluent emerges as the vital connective framework within this paradigm, facilitating uninterrupted real-time data synchronization across disparate systems. By bridging ingestion pipelines, data lakes, and batch-oriented workflows, Confluent guarantees that information arrives at designated destinations precisely when required. Absent this foundational layer, the construction of cohesive generative AI solutions becomes substantially more arduous, often resulting in delayed or inconsistent outputs.

Complementing this streaming backbone, Amazon Bedrock delivers a fully managed service granting access to an array of foundation models sourced from leading providers such as AI21 Labs, Anthropic, Cohere, Meta, Mistral AI, Stability AI, and Amazon itself. Bedrock supports diverse experimentation modalities, enables model customization through fine-tuning or extended pre-training, and permits the orchestration of intelligent agents without necessitating extensive coding expertise. From a security perspective, Bedrock rigorously prohibits the incorporation of customer data into baseline models, maintains isolation for fine-tuned variants, implements encryption protocols, enforces granular access controls aligned with AWS identity management, and adheres to certifications including HIPAA, GDPR, SOC, ISO, and CSA STAR.

The differentiation of generative AI applications hinges predominantly on proprietary datasets. Organizations possessing comparable access to foundation models achieve superiority by capitalizing on unique internal assets. Three principal techniques harness this advantage: retrieval-augmented generation incorporates external knowledge directly into prompt engineering; fine-tuning crafts specialized models tailored to domain-specific corpora; continued pre-training broadens model comprehension using enterprise-scale information repositories.

For instance, an online travel agency might synthesize personalized itineraries by amalgamating live flight availability, client profiles, inventory levels, and historical preferences. AWS furnishes an extensive suite of services accommodating unstructured, structured, streaming, and vectorized data formats, thereby enabling seamless integration across heterogeneous sources while preserving lifecycle security.

Orchestrating Real-Time Contextual Enrichment and Inference Mechanisms

Confluent assumes a critical position by directly interfacing with vector databases, thereby assuring that conversational AI frameworks consistently operate upon the most pertinent and current information. This integration transcends basic data translocation, emphasizing the delivery of contextualized, AI-actionable content.

Central to this orchestration is Flink Inference, a sophisticated capability within Confluent Cloud that facilitates instantaneous machine learning predictions through Flink SQL syntax. This approach dramatically simplifies the embedding of predictive models into operational workflows, yielding immediate analytical outcomes and supporting real-time decision-making grounded in accurate, contemporaneous data.

Configuration commences with establishing connectivity between Flink environments and target models utilizing the Confluent command-line interface. Parameters specify endpoints, authentication credentials, and model identifiers—accommodating various Claude iterations alongside other compatible architectures. Subsequent commands define reusable prompt templates, allowing baseline instructions to persist while dynamic elements vary per invocation. Finally, data insertion invokes the ML_PREDICT function, passing relevant parameters for processing.

Architecturally, the pipeline initiates with document or metadata publication to Kafka topics, forming ingress points for downstream transformation. Where appropriate, documents undergo segmentation into manageable chunks to promote parallel execution and enhance computational efficiency. Embeddings are then generated for each segment leveraging Bedrock or Anthropic services, after which these vector representations—accompanied by original chunks—are indexed within a vector store such as MongoDB Atlas.

To accelerate adoption, dedicated quick-start repositories provide deployable templates encapsulating this workflow. Notably, these templates incorporate structured document summarization via Claude, converting tabular or hierarchical data into narrative abstracts suitable for natural language querying.

Interactive sessions begin through API gateways or direct Kafka clients, enabling bidirectional real-time communication. User queries generate embeddings, which subsequently retrieve semantically aligned documents from the vector repository. Retrieved artifacts, augmented by available streaming context, inform prompt construction to maximize relevance and precision. The resultant engineered prompt undergoes processing by Claude on Anthropic Cloud, producing responses that reflect both historical knowledge and live situational awareness.

Efficiency enhancements include conversational summarization to mitigate token proliferation and refine large language model performance. Empirical observations indicate that Claude-generated query reformulations for vector retrieval substantially outperform direct human phrasing, yielding markedly superior document recall.

CREATE MODEL anthropic_claude WITH (
  'connector' = 'anthropic',
  'endpoint' = 'https://api.anthropic.com/v1/messages',
  'api.key' = 'sk-ant-your-key-here',
  'model' = 'claude-3-opus-20240229'
);

CREATE TABLE refined_queries AS
SELECT ML_PREDICT(
  'anthropic_claude',
  CONCAT('Rephrase for vector search: ', user_query)
) AS optimized_query
FROM raw_interactions;

Flink’s value proposition extends beyond connectivity to encompass cost-effectiveness, automatic scaling for voluminous workloads, and native interoperability with extensive ecosystems. Confluent maintains certified integrations across major AWS offerings, prominent data warehouses including Snowflake and Databricks, and leading vector databases such as MongoDB. Anthropic models remain comprehensively accessible via Bedrock, reflecting strategic collaborations spanning product interfaces to silicon-level optimizations.

Analytical Implications and Strategic Trajectories for Enterprise AI Deployment

The methodological synthesis presented—encompassing streaming orchestration, managed model accessibility, and safety-oriented language processing—fundamentally reconfigures retrieval-augmented generation from static knowledge injection to dynamic reasoning augmentation. This evolution proves indispensable for domains requiring precise interpretation, such as regulatory compliance or legal analysis.

Strategic ramifications are profound. Organizations unlock domain-specific differentiation by leveraging proprietary datasets within real-time contexts, achieving decision-making superiority unattainable through generic models alone. Governance frameworks scale securely, accommodating enterprise-grade requirements without sacrificing velocity.

Persistent challenges, including data provenance assurance and model drift mitigation, necessitate ongoing refinement protocols. Future pathways envision declarative inference paradigms wherein prompts and policies are codified as infrastructure, alongside hybrid architectures merging vector search with continuous streaming for anticipatory intelligence.
