The AI Firewall: Using Local Small Language Models (SLMs) to Scrub PII Before Cloud Processing (Tue, 10 Feb 2026)
As organizations increasingly rely on powerful cloud-based AI services like GPT-4, Claude, and Gemini for sophisticated text analysis, summarization, and generation tasks, a critical security concern emerges: what happens to sensitive data when it's sent to external AI providers? Personal Identifiable Information (PII) — including names, email addresses, phone numbers, social security numbers, and financial data — can inadvertently be exposed during cloud AI processing. This creates compliance risks under regulations like GDPR, HIPAA, and CCPA, and opens the door to potential data breaches.

OCI Images as Kubernetes Volumes: A New Era for Data Management (Tue, 10 Feb 2026)
A new volume type has recently joined the Kubernetes ecosystem: the image volume. This feature, available starting with version 1.35.0 and currently in beta, promises to change how we manage static data and configurations in our clusters. The relevance of this volume type has been growing in cloud-native environments. Several applications already use container images to store information in OCI (Open Container Initiative) format. Popular tools such as Falco (for security rules), Kyverno (for policies), and FluxCD (for deployment management) are clear examples of this trend. Now, this capability is native to Kubernetes.

Visualizing Exposure Bias Using Simulation (Tue, 10 Feb 2026)
Abstract Randomization is a foundational assumption in A/B testing. In practice, however, randomized experiments can still produce biased estimates under realistic data collection conditions. We use simulation to demonstrate how bias can emerge despite correct random assignment. Visualization is shown to be an effective diagnostic tool for detecting these issues before causal interpretation. Introduction A/B testing is widely used to estimate the causal impact of product changes. Users are randomly assigned to control (C) or treatment (T), and differences in outcomes are attributed to the experiment. Randomization is intended to balance user characteristics across groups when assignment occurs at the user level. However, even with correct random assignment, the observed segment mix can differ because real experiments are often analyzed on a filtered or triggered subset of users. Eligibility rules, exposure conditions, logging behavior, and data availability can vary by variant due to trigger logic, instrumentation loss, device or browser differences, and latency. As a result, treatment and control may represent different effective populations.

A Pattern for Intelligent Ticket Routing in ITSM (Tue, 10 Feb 2026)
In the world of IT Service Management (ITSM), the Service Desk often acts as a human router. A ticket comes in, a coordinator reads it, checks a spreadsheet to see who is on shift, remembers who is good at databases versus networking, and then assigns the ticket. This process is slow, subjective, and prone to cherry-picking (where engineers grab easy tickets and ignore hard ones). It creates a bottleneck that increases Mean Time to Resolution (MTTR).
