DevSecConflict: How Google Project Zero and FFmpeg Went Viral For All the Wrong Reasons

Aggregated on: 2025-11-24 21:41:12

Security research isn’t a stranger to controversy. The small community of dedicated niche security teams, independent researchers, and security vendors working on new products finds vulnerabilities in software and occasionally has permission to find and exploit them. This security industry has always had a fraught relationship with the law and the terms of service of the organisations they target, as notoriety is prioritized over legalities. Regardless of the true motives of security researchers, it is difficult to argue that this vulnerability hunting is done with no genuine desire to improve security, in addition to producing a conference talk or two. To avoid legal threats, many researchers opt to avoid commercial software, products, and applications and instead turn their attention to open source. Open-source teams welcome contributions to improve security, offer transparency through pull requests, and are used throughout the industry. Where closed-source software may respond with a legal threat, open source responds with an enthusiastic thank-you, allowing security researchers to make an impact and talk about their work.

Aggregated on: 2025-11-24 20:41:12

The evolution of conversational AI has introduced another dimension of interaction between businesses and users on the internet. AI chatbots have become an inseparable part of the digital ecosystem, which is no longer restricted to customer service or personalized suggestions. Chatbots have the potential to share sensitive data, break user trust, and even create an entry point to cyberattacks. This renders the security of conversational AI a matter of urgent concern to enterprises that embrace AI chatbot development services for websites.

How to Build Real-Time Transaction Monitoring Systems With Streaming Data

Aggregated on: 2025-11-24 19:41:12

The rate at which financial transactions are conducted in the United States has been increasing at a tremendous rate over the last few years. Billions of dollars flow through networks in seconds as digital wallets, instant peer-to-peer payments, and online banking emerge. This presents opportunity as well as risk. Real-time transaction monitoring systems with streaming data have become a security and compliance priority in financial institutions due to the importance of detecting suspicious behavior in real-time. Although the traditional monitoring model typically assumes the use of batch processes to analyze the data hours after it was captured, the recent threat landscape does not tolerate any speed. In the year 2023, the Federal Trade Commission reported that the American people had lost over $10 billion to fraud, the highest recorded amount. Even one day of delay can be converted into millions of avoidable losses. Streaming data technologies offer a way forward, where financial systems will be able to process and assess transactions in real-time.

Building a Retrieval-Augmented Generation (RAG) System in Java With Spring AI, Vertex AI, and BigQuery

Aggregated on: 2025-11-24 18:41:11

Retrieval-augmented generation (RAG) is quickly becoming one of the most powerful design patterns for AI applications. It bridges the gap between general-purpose large language models (LLMs) and your specific enterprise data. In this article, we’ll walk through how to build a complete RAG pipeline in Java using Spring Boot, Vertex AI’s Gemini embeddings, Apache PDFBox, and BigQuery Vector Search. You will see how to do the following, wrapped in a Spring Boot app with a simple web UI:

Creating an MCP Client With Spring AI

Aggregated on: 2025-11-24 17:41:11

MCP servers extend the functionality of a large language model (LLM). Inference engines allow you to define the MCP servers, but often you will need to write an MCP client yourself. In this blog, you will learn how to do so using Spring AI. Enjoy! Introduction In a previous post, you learnt how to create an MCP server using Spring Boot and Spring AI. The MCP server provides four tools:

The Right to Be Forgotten in Event-Driven Data Products

Aggregated on: 2025-11-24 16:41:11

Companies operating under regulatory frameworks such as GDPR, CPPA, and other privacy laws increasingly find themselves under pressure to enforce strict and timely retention and deletion policies for customer data. These regulations not only require data to be stored securely but also mandate that organizations delete customer information wherever it exists when the customer requests deletion, upon customer exit, or when retention windows expire. In practice, this "right to be forgotten" means that every copy, transformation, and analytical artifact referencing that individual must be identified and purged within defined timeframes. In many organizations, especially those with complex analytical ecosystems, this is far more difficult than it sounds. Operational systems often have clear deletion semantics, but analytical platforms (data lakes, warehouses, dashboards, machine learning pipelines) tend to accumulate replicated and transformed copies of customer data that sit outside the operational flow. When a deletion occurs upstream, downstream analytical systems may not hear about it, may not react in time, or may not have a reliable mechanism to trace lineage and apply deletions consistently. This gap creates compliance risk, audit failures, and fragmentation across analytical domains.

Architectural Evidence in Enterprise Java: Making Domain-Driven Design Visible

Aggregated on: 2025-11-24 15:41:11

One subtle challenge in software architecture is that architectural thinking can feel detached from the codebase. We draw diagrams, define layers, identify responsibilities, and craft a coherent structure — yet the moment implementation begins, those architectural ideas fade into the background. Over time, systems drift not because developers ignore design, but because the code itself provides almost no way to express that design. This tension is well documented. In Just Enough Software Architecture, George Fairbanks argues that programming languages lack constructs for directly representing architectural concepts. Java lets us model types, fields, methods, and packages, but offers no native way to encode ideas such as “presentation layer,” “domain logic,” “aggregate root,” or “infrastructure boundary.” Without these cues in the code, architecture becomes optional, verbal, and fragile.

Revolutionizing Supply Chain Optimization with AI-Driven Constraint Programming

Aggregated on: 2025-11-21 13:11:10

Optimizing the supply chain has been no easy task. Success entails making decisions on the firm's supply, production, inventory, and logistics functions, all in the real world where demand is not fixed, suppliers are not infinite, and disturbances are not rare. Conventional optimization approaches are suitable for steady-state scenarios but fail in dynamic and complex environments. AI and CP are the technologies that are changing the way of supply chain management and enabling organizations to build adaptive, efficient and resilient supply networks. However, in this article I will explain how AI constraint programming works, the how of it, and how AI professionals can develop high-level applications using it.

Software Testing in the AI Era - Evolving Beyond the Pyramid

Aggregated on: 2025-11-21 12:11:10

If the 1990s was the internet era and the 2010s was the smartphones era, then it's clear that the 2020s will be defined by Large Language Models (LLMs) and AI tools. In a decade where nearly every field is being defined by advancements in AI, software testing is no exception. Software testing is a fundamental building block in the foundation upon which software quality assurance is built. The development of testing techniques has a long and storied history stretching back to the early days of software development itself.

Deploying a Serverless Application on Google Cloud

Aggregated on: 2025-11-20 20:11:10

Deploying a serverless application is a modern approach to building scalable and cost-efficient software without managing the underlying infrastructure. This blog will walk you through the process with a practical Python example deployed on Google Cloud Functions, one of the major cloud providers offering serverless capabilities. What Is Serverless Deployment? Serverless deployment means that developers write code without worrying about servers or infrastructure. The cloud provider dynamically manages the resource allocation, scaling, and availability of the functions. You are billed only for the actual execution time of your code, making it highly cost-effective and efficient. Serverless architectures promote modular, event-driven development, perfect for microservices or APIs.

Advanced Usage of Decodable in Swift: Handling Dynamic Keys

Aggregated on: 2025-11-20 19:11:10

When your backend sends responses that don't follow a consistent structure, Swift's Decodable system can begin to reveal its limitations. It expects structure. Predictability. Stability. However, real-world APIs — especially those powering social feeds, content backends, or any CMS-driven application — rarely fit that mold. This article takes a look under the hood of Swift's decoding system. The goal isn't to memorize recipes, but to understand what's really happening so you can build decoding logic that scales with the unpredictable nature of your APIs.

The Slow/Fast Call Orchestration: Parallelizing for Perception

Aggregated on: 2025-11-20 18:11:09

You hit “play” on a video. Seconds pass, but nothing happens — just that spinning wheel. It’s a small delay, but it feels huge. Now imagine a different experience: the video starts playing almost instantly. The first few seconds are slightly lower resolution, but by the time you register it, the stream has already sharpened to full HD. On slower networks — the kind that can sustain HD once the stream stabilizes but are too sluggish to start it quickly — this change is transformative. A tiny shift in how data is delivered can completely reshape how fast the experience feels. A moment that once felt like waiting suddenly becomes a moment of progress.

How I Cut Kubernetes Debugging Time by 80% With One Bash Script

Aggregated on: 2025-11-20 17:11:09

Here's the truth about Kubernetes troubleshooting: 80% of your time goes into finding WHAT broke and WHERE it broke. Only 20% goes into actually fixing it. For months, I lived this reality, managing eight Kubernetes clusters. Every issue followed the same pattern: 30 minutes of kubectl detective work, five minutes to fix the actual problem. I was spending hours hunting for needles in haystacks. Then one weekend, I flipped that ratio. Every Monday at 8 AM, our team's Teams chat explodes. "Hey, the dashboard is down." "Perf team can't access their pods." "Build agents crashed overnight."

Beyond Vector Databases: Integrating RAG as a First-Class Data Platform Workload

Aggregated on: 2025-11-20 16:11:09

Retrieval-augmented generation (RAG) has become critical for groundbreaking large language models (LLMs) in enterprise knowledge, yet more than half of them failed in production due to retrieval latency or data issues. The root cause isn’t the LLM or embedding model used in RAG; it is due to treating RAG as an add-on instead of an integrated RAG, where retrieval and generation evolve together. The Production RAG Crisis The Promise vs. Reality RAG is supposed to enhance the accuracy and relevance of LLMs by retrieving relevant context, augmenting the prompt, and generating grounded answers. It is designed to mitigate hallucinations, one of the most significant challenges facing large language models.

Kubernetes CSI Drivers

Aggregated on: 2025-11-20 15:11:10

In the Kubernetes ecosystem, storage has many facets. The most obvious ones are StorageClass, PersistentVolume, and PersistentVolumeClaim. We have all used them to get storage mounted to pods, but that is just the surface of how storage really gets plugged into Kubernetes pods. Beneath the PVs and PVCs lies a complex standard consisting of multiple components, and every component is crucial for it to work. In this article, I am going to dive deep into how this standard works, what each component does, and build a working architecture. But first, let’s define the standard. The official definition of CSI is: a standard interface that enables container orchestration systems (like Kubernetes) to expose arbitrary storage systems to containers in a consistent way — or, as stated more formally, the Container Storage Interface (CSI) is a specification that enables storage vendors to develop plugins that expose storage systems to containerized workloads in a standardized, portable way.

Why Internal Tools Waste So Much Engineering Time

Aggregated on: 2025-11-20 14:11:09

Internal tools rarely get the same attention as customer-facing products, but the pain is just as real. Modern systems can fail in countless ways, and when they do, engineers spend hours untangling dependencies just to locate the root cause. Inside most organizations, these tools are business-critical: powering finance, operations, sales, or logistics. Yet their support workflows are often ad hoc. Issues get reported through chat threads or informal tickets, context is incomplete, and debugging turns into a relay race across teams.

Building Smarter Systems: Architecting AI Agents for Real-World Tasks

Aggregated on: 2025-11-20 13:11:09

In modern software architecture, “AI agent” can mean an autonomous, intelligent component, not necessarily a machine-learning model. In this guide, we focus on building smart, event-driven, and rule-based agents that react to events, apply rules, and coordinate tasks without any machine learning. The goal is to design systems that are resilient, scalable, and maintainable, using tried-and-true patterns instead of AI complexity. Event-Driven Agents: Core Principles Event-driven architecture (EDA) is a design model where components communicate by producing and responding to events. In contrast to a traditional request/response model, where one component waits on another, an event-driven system allows asynchronous, real-time communication between decoupled components. The key idea is that when something of interest happens (an event), the system notifies all parts that subscribe to that event, letting them react immediately.

Serverless vs. Containerized Applications: Which is the Best Choice?

Two prominent methodologies, Serverless and Containers, both offer distinct functionalities and are powerful. But what is the right for you? In this article, we will explore technicalities, key differences, when to use each, and much more! About Serverless Architecture As the term "Serverless" implies, it refers to developers developing and executing applications without managing infrastructure. Cloud providers like AWS, Google Cloud Platform, and Azure manage maintenance, scaling, and provisioning themselves.

Iceberg Compaction and Fine-Grained Access Control: Performance Challenges and Solutions

Aggregated on: 2025-11-19 20:11:09

Modern data lakes increasingly rely on Apache Iceberg for managing large analytical datasets, while organizations simultaneously demand fine-grained access control (FGAC) to secure sensitive data. However, combining these technologies can create unexpected performance bottlenecks that significantly impact query execution times. This article explores the technical challenges that arise when implementing FGAC on Iceberg tables and provides practical guidance for choosing the right processing engine for your use case. Understanding Iceberg Compaction Apache Iceberg is an open table format designed for huge analytical datasets. One of its core features is compaction — the process of combining smaller data files into larger, more efficient ones to optimize query performance and reduce metadata overhead.

Good CI Is the Key to a Great Developer Onboarding Experience

Aggregated on: 2025-11-19 18:26:09

I have spent the last 20 years working with large enterprises. First, as a developer myself, and later, helping teams across different stages of their journey. One of the biggest challenges for any engineer, whether new or experienced, is becoming productive quickly. For technical employees, especially those hired to write code, nothing builds confidence faster than being able to make a change to an existing repository and immediately know whether that change is good before it gets merged. A good CI system should automate every step and execute quickly to provide clear signals that definitively answer the question: “Is this change good enough to merge?”

Faster Build & Test Loops, Better DevX

Aggregated on: 2025-11-19 13:26:09

I was listening to a podcast recently about building agents, and they mentioned that writing code was never the bottleneck; it was everything around code writing that took the most time. So true, I thought. Of course, there’s much more to delivering software to customers, but I’ve always cringed at how much inefficiency exists in a typical build and test setup, and how little effort teams often put into addressing these bottlenecks. Recently, while testing a new build tool, I noticed that when it worked, it improved my build efficiency by more than 50%. That’s when it struck me how much productivity I had been losing and even more surprisingly, how unaware I’d been of it, simply because I had grown accustomed to those inefficiencies.

Meta Data: How Data about Your Data is Optimal for AI

Aggregated on: 2025-11-19 12:26:09

Introduction All AI models are built on data collected from a wide range of sources, including vast internet repositories. The real challenge is not just gathering this raw information, but extracting its value. Thanks to Data labeling and neural network architectures, significant progress has been made in turning unstructured data into intelligent models. Data is gold. As AI models parse all kinds of data from numerous sources, a model fed with more descriptive data, will perform better. We’ll talk about what metadata is and how this data about data increases AI efficiency.

Building Gateway Analytics: My Journey to Making API Traffic Data Useful

Aggregated on: 2025-11-18 18:11:08

APIs are everywhere today. Whether it's buying something online, logging into a mobile app, or streaming a movie, an API is always working behind the scenes. Over the last decade, APIs have become the backbone of modern software systems. As an application scales, the volume of API calls increases rapidly, and managing them becomes more complex. This is where API gateways come into action. An API gateway acts as an entry point for all internal or external API traffic. It sits in front of the backend services and handles responsibilities such as authentications, routing, rate limiting, logging, performance monitoring, and more.

Embedding Ethics Into Multi-AI Agentic Self-Healing Data Pipelines

Aggregated on: 2025-11-18 17:11:08

The race to design a fully autonomous system is fostering innovations in the development of modern data systems. Developers are striving to create data ecosystems that are self-correcting and have minimal downtime so as to manage data movement effectively within their organizations. Due to such a drive for automation, the use of self-healing data pipelines has increased rapidly. A conventional data pipeline consists of data processing elements connected in a relevant manner to move data between two different data systems. For example, extracting data from IoT devices, such as temperature sensors, and loading it into an analytical database for monitoring forms a simple ELT data pipeline. Such traditional pipelines are prone to limitations, including downtime, crashes, low scalability, and excessive monitoring overhead.

NVIDIA GPU Operator Explained: Simplifying GPU Workloads on Kubernetes

Aggregated on: 2025-11-18 16:11:08

While GPUs have long been a staple in industries like gaming, video editing, CAD, and 3D rendering, their role has evolved dramatically over the years. Originally designed to handle graphics-intensive tasks, GPUs have proven to be powerful tools for a wide range of computationally demanding applications. Today, their ability to perform massive parallel processing has made them indispensable in modern fields such as data science, artificial intelligence and machine learning (AI/ML), robotics, cryptocurrency mining, and scientific computing. This shift was catalysed by the introduction of CUDA (Compute Unified Device Architecture) by NVIDIA in 2007, which unlocked the potential of GPUs for general-purpose computing. As a result, GPUs are no longer just graphics accelerators; they’re now at the heart of cutting-edge innovation across industries. In this blog post, we will discuss the NVIDIA GPU operator on Kubernetes and how to deploy it on the Kubernetes Cluster.

Building a Containerized Quarkus API on AWS ECS/Fargate With CDK

Aggregated on: 2025-11-18 15:11:08

In a three-article series published recently on this site (Part 1, Part 2, Part 3), I've been demonstrating the power of the AWS Cloud Development Kit (CDK) in the Infrastructure as Code (IaC) area, especially when coupled with the ubiquitous Java and its supersonic/subatomic cloud-native stack: Quarkus. While focusing on the CDK fundamentals in Java, like Stack and Construct, together with their Quarkus implementations, this series was a bit frugal as far as the infrastructure elements were concerned. Indeed, for the sake of clarity and simplification, the infrastructure used to illustrate how to use the CDK with Java and Quarkus was inherently consensual. Hence, the idea for a new series, of which this article is the first, is a series less concerned with CDK internals and more dedicated to the infrastructure itself.

How Agentic AI Enhances API Testing

Aggregated on: 2025-11-17 16:11:08

Many developers have used generative artificial intelligence to create or complete code, but few have leveraged agentic AI. This AI subset can reason and execute complex tasks autonomously. Its high level of independence and unique proactive approach make it ideal for application programming interface (API) testing. Understanding Agentic AI’s Role in API Testing The use of AI in API testing is relatively new, but well-documented. Researchers have demonstrated the effectiveness of large language models (LLMs) in API testing, particularly when a single test case corresponds to multiple values. Experimental results show precision can reach as high as 100% under stringent conditions, but recall falls below 20%. Under relaxed conditions, recall rates approach 90% while maintaining high precision.

When AWS went dark last week, the internet seemed to take a deep breath with it. Streaming services froze, fintech apps stalled, and even smart home devices blinked out. For a few hours, much of the digital world that relied on AWS ran on borrowed patience. It wasn't just an outage; it was a reminder. A reminder that even the most reliable cloud can still have cloudy days (pun intended).

Integrating AWS With Okta for Just-in-Time (JIT) Access: A Practical Guide From the Field

Aggregated on: 2025-11-17 14:11:08

When our engineering team decided to tighten security around AWS access without slowing developers down, we quickly ran into a familiar trade-off — speed vs. control. We had engineers needing quick access to production for debugging, deployments, and performance checks, but long-lived IAM users and static credentials made our compliance team nervous. That’s where Okta-driven Just-in-Time (JIT) access came in. This post walks through how we set up AWS + Okta integration to give developers on-demand, time-bound access to AWS using SAML federation and Okta Workflows. I’ll share exactly what worked, what didn’t, and what we learned while making it production-ready.

The Software Architect's Mandate: Treating ChatGPT as a System, Not a Search Engine

Aggregated on: 2025-11-17 12:11:08

As a software architect, I've spent years designing systems that transform inputs into optimal outputs. When I first encountered ChatGPT, I recognized a familiar pattern: most users were treating it like a poorly designed API—sending malformed requests and wondering why the responses were suboptimal. After analyzing thousands of interactions and reverse-engineering what makes for effective usage versus ineffective usage, I've identified the architectural principles that unlock ChatGPT's true potential. This isn't about prompt templates or tricks, but rather about really understanding the system architecture and designing your interactions in light of it.
