# Enhancing Certificate Transparency Monitoring: Filtering Out Cloudflare-Managed Certificates Certificate Transparency (CT) monitoring is a crucial security feature that helps organizations detect misissued certificates for their domains. Since launching this feature in public beta in 2019, Cloudflare has been emailing subscribers whenever a new TLS certificate appears in a public CT log for one of their domains. However, as the feature gained adoption among our 650,000+ customer domains, we identified a significant noise problem that needed addressing. ## The Noise Problem Cloudflare issues a large volume of certificates on behalf of our customers through Universal SSL, Advanced Certificate Manager, and…

**Cisco and Rockwell Automation Launch Software-Defined Manufacturing Architecture to Bridge IT and OT** In a move aimed at closing the long-standing divide between enterprise IT and factory-floor operations, Cisco and Rockwell Automation have introduced a Full-Stack Software-Defined Manufacturing architecture. This joint initiative is designed to seamlessly connect plant-floor systems with higher-level computing environments, enabling manufacturers to harness industrial data for analytics and artificial intelligence (AI). At its core, the architecture merges Cisco’s expertise in software-defined networking with Rockwell Automation’s leadership in software-defined automation. The solution creates secure, reliable data pathways that move real-time operational data from equipment, sensors, and controllers…

**Okta Proposes Identity‑Scoped MCP Tool Lists as a Way to Cut AI Agent Token Costs** Large language models are increasingly being used as autonomous “agents” that can call tools, query databases, and take actions on behalf of users. To support this, the Model Context Protocol (MCP)—originally developed by Anthropic—has gained traction as a standardized way for AI agents to discover and connect to tools and data sources. However, as Okta highlights in a recent post, every tool exposed by an MCP server is packaged into the prompt sent to the model on each turn, creating significant hidden costs and security…

**Demystifying Backpropagation: From Concept to Computation** Backpropagation is the engine behind training neural networks, enabling them to learn from data by efficiently calculating gradients. In this article, we’ll explore why backpropagation is essential, how it reuses intermediate computations, and how it provides a systematic approach to gradient computation for networks of any complexity. — ### Why Recompute the Same Gradients? When calculating gradients for a neural network’s parameters — such as weights and biases — it’s tempting to apply the chain rule independently for each parameter. However, doing so leads to redundancy. For instance, when computing the gradient for weight…

**The End of Rare: Defending in an Era of AI-Driven Exploits** The cybersecurity landscape is undergoing a dramatic shift, moving away from traditional reactive defenses. According to David Weston, a senior security manager at Microsoft, the rise of artificial intelligence (AI) is fundamentally changing the economics of cyber attacks. Where developing and deploying exploits once required significant time, effort, and expense, AI tools are now making vulnerability discovery and exploit development cheaper, faster, and more scalable. This new reality demands a fundamental change in how organizations approach security. ### The AI Acceleration of Vulnerability Discovery Weston highlighted this paradigm shift…

**The Great Bitcoin Exodus: Coldcard Breach Triggers $130 Million Exodus as 233,000 BTC Moves to Safety** In the wake of what is now being called the worst hardware wallet exploit in Bitcoin’s recent history, the cryptocurrency world is witnessing a massive migration of capital. The Coldcard firmware vulnerability, discovered in late July 2026, has resulted in the drainage of approximately 2,100 BTC—valued at close to $130 million—through a series of coordinated attacks. However, the true story lies not just in the stolen funds, but in the far larger movement of Bitcoin that occurred in response to the breach. — ###…

**OPM’s Workforce Challenge: A Cautionary Tale from the Frontlines** A recent analysis by the Government Accountability Office (GAO) has turned OPM, the very agency tasked with managing the federal workforce, into a compelling case study on the complexities of federal workforce transformation. The findings reveal a startling paradox: while OPM has been a primary driver of change across the federal government, it has simultaneously undergone a severe contraction of its own workforce. Between December 2024 and March 2026, the agency lost a staggering 34% of its personnel, a rate of decline significantly higher than the overall 11% drop seen across…

**Sparky Linux Brings Back 32-Bit Support: A Lifeline for Older PCs** *By Jack Wallen, ZDNET* In an era where 64-bit processors have been the standard for well over a decade, and Microsoft has signaled the end of the road for 32-bit applications, it might seem surprising that a major Linux distribution is reviving support for 32-bit hardware. However, Sparky Linux has done exactly that, reintroducing its 32-bit architecture support with its latest release. This move is a practical lifeline for millions of older PCs still in use around the world. The decision by the Sparky Linux development team comes after…

**Agentic Document Parsing: A Deterministic Dispatcher for Enterprise RAG** In enterprise Retrieval-Augmented Generation (RAG), few topics are more overhyped—and simultaneously more misunderstood—than “agentic AI.” The principle often boils down to a single idea: *let the model decide*. While this makes sense for a general-purpose assistant, it is dangerous for enterprise RAG pipelines where answers drive real decisions. In such contexts, we must know every step and control the flow between them. This article takes that stance to the next logical layer: choosing the right parsing method for each document. Rather than letting an LLM decide, we build a **deterministic dispatcher**…

**How to Easily Install Python on Windows in 2024 (5 Methods)** Installing Python used to involve downloading the correct installer, checking the right boxes, and manually adding Python to your system PATH. While that still works, modern tools have made the process much faster and more streamlined. Whether you’re a beginner or a seasoned developer, there’s a method that fits your workflow. This article walks you through five simple ways to install Python on Windows, helping you choose the best option based on your needs. — ### 1.
