Platform

Pulumi has made its AI-powered agents available in preview for its infrastructure-as-code platform. The new Pulumi Neo feature introduces a set of AI agents that autonomously diagnose issues and complete tasks when permitted, allowing users to focus on higher-level tasks while leveraging artificial intelligence for routine operations and process automation.

A critical vulnerability in Microsoft's Azure Active Directory Graph API allows attackers to impersonate any Global Admin without logs or telemetry, granting them full access to a victim tenant. The vulnerability was caused by undocumented impersonation tokens and was addressed by Microsoft within days, but its impact remains significant due to brute-forcing netIds.

PureVPN's IPv6 implementation has two major security vulnerabilities: IPv6 leaks occur when reconnecting or suspending Wi-Fi, allowing users to access the internet without VPN protection. The client also wipes firewall state at connection time but fails to restore it upon disconnection, leaving systems more vulnerable to attacks, with no acknowledgment from PureVPN received so far.

A new article offers a step-by-step guide on hacking webhooks for threat hunters and bug bounty hunters, highlighting common vulnerabilities such as leaks in public indexes, pipeline misuse, and lack of verification. It provides tips on finding webhooks reliably and examples of detection rules to mitigate security issues related to these callbacks.

Kubernetes now exposes device health information in the .status field for Pods, enabling users and automation tools to quickly diagnose issues caused by device failures. This feature introduces a new gRPC service, DRAResourceHealth, allowing DRA drivers to stream device health updates to the Kubelet, enhancing Pod status checks.

Ubuntu 25.10's transition to Rust Coreutils has revealed performance issues with certain utilities, such as base64 and cksum, which are up to 17x slower than their C-based GNU counterparts. However, upstream developers are actively working to address these gaps, including a recent fix for the base64 utility, to improve Ubuntu's stability prior to release in October.

Platform warm-up refers to the time it takes for a system or platform to regain operational status after a restart or maintenance period. This phenomenon can cause performance issues and impact high-traffic volumes if not addressed. Implementing strategies like smoke tests, health checks, pre-fetching data, and canary releases can mitigate this issue.

To restart pods in Kubernetes, there isn't a single command, but rather seven methods that vary in approach and application. This article explores these alternatives using kubectl, offering insights into best practices for each scenario to help developers manage pods effectively, address issues like stuck or outdated pods, and perform clean restarts.

MongoDB has introduced an application modernization platform, AMP, which leverages AI agents to analyze and convert legacy applications into compatible code for its document database. The platform aims to simplify the modernization process for businesses, allowing them to migrate outdated systems to more efficient and modern applications using a scalable solution.

A new beta version of an API has been released to address a critical issue with CSI drivers implementing the ListSnapshots RPC call. The updated v1beta2 API includes a VolumeSnapshotInfo struct, providing more detailed information about individual volume snapshots. Conversion from v1beta1 objects is facilitated through a webhook, paving the way for future adoption and testing of the feature.

GitHub has launched the MCP Registry, a centralized hub for discovering and deploying Model Context Protocol (MCP) servers. Backed by partners including Figma, Postman, and HashiCorp, the registry aims to simplify integration, enhance security, and accelerate AI-powered development workflows using Oracle, Java, and OpenTelemetry technologies among developers.

A new article provides a comprehensive checklist for implementing mature reliability practices in software engineering, covering key areas such as culture, ownership, observability, and security, to create a reliable system with clear ownership, measurable SLOs, and real-time visibility. This checklist aims to establish a strong foundation for reliability and success.

A simulation guide for a Senior DevOps Engineer interview at Uber shares two rounds of technical questions. The first round tests skills on core systems, Linux, and cloud technologies through practical scenarios such as zero-downtime rollouts and DNS resolution issues. The second round presents reliability and fire drill scenarios involving Kafka and etcd.

An architecture diagram for AWS's Intelligent Document Processing sample solution has been criticized for discrepancies between its actual implementation and depicted system, leading to misdirection for inexperienced developers. A revised sequence diagram format highlights accurate interactions and rectifies inaccuracies, prioritizing onboarding and reference purposes over marketing simplicity.

Treating OpenAPI as a single source of truth for APIs offers numerous benefits. This approach reduces miscommunication and automates code generation, allowing teams to catch breaking changes early through automated testing. By writing the API specification before implementation code, parallel work can be done with mock servers and stubs from the same agreed-upon contract.

NotebookLM is an AI-powered research tool that helps developers create personalized knowledge management systems by synthesizing information and providing intelligent assistance. It's particularly useful for accelerating language and framework learning, documenting codebases, and debugging. The article shares five use cases and best practices to get the most out of NotebookLM for maximum productivity gains.

The evolution of take-home interviews in tech has been shaped by AI-powered coding tools like Claude, rendering them less effective as screening tools. However, they can still assess a candidate's deep thinking skills, essential for real-world engineering work. Take-home interviews should focus on critical and creative thinking, rather than technical proficiency.

Paul Boag argues that traditional personas in UX design are often overworked yet underutilized. He proposes simplifying their creation to provide a lightweight tool for designers, leveraging functional personas to deliver valuable insights and breathe new life into this stale UX asset, streamlining the process for improved results.
