Missed Windows 11 Secure Boot? Don’t panic, Microsoft is still pushing it in the coming months

Microsoft reassured Windows 11 and Windows 10 users that their PCs will continue to boot normally and receive updates even if they have not yet received the new Secure Boot 2023 certificates. The rollout of these certificates is expected to continue over the upcoming months. The initial Secure Boot certificate expired on June 24, 2026, and Microsoft has been replacing older 2011 certificates since 2024. The latest update, KB5101650, transitioned Windows 11 to OS builds 26200.8875 and 26100.8875 for versions 25H2 and 24H2, respectively. The 2023 certificates replace older certificates with modern cryptographic standards, allowing Microsoft to deliver DBX revocation updates without interruption. Devices using the 2011 KEK can only receive DBX updates signed with that key, which is no longer valid after June 24. Microsoft has been rolling out the 2023 certificates for the past two years, and many devices remained in a yellow or red status by the June deadline. To check Secure Boot status, users can navigate to Windows Security > Device Security. A green checkmark indicates successful application of the certificates, while yellow and red alerts indicate compatibility issues or firmware incompatibility. PCs that are older or operating in Legacy BIOS mode will not receive the updates. Windows 10 also receives Secure Boot updates, but enrollment in Extended Security Updates (ESU) is required.

The most online generation is also the least protected: over half of Gen Z have already faced a cyberattack – Adaderana Biz English

New research from Kaspersky surveyed 7,200 respondents globally and found that Generation Z spends 57% of their time online, primarily using smartphones (67% identify them as their main device). While 59% of Gen Z feel confident in navigating the digital landscape, only 28% consider their digital skills advanced. Alarmingly, only 27% use antivirus software on their mobile devices, and over half (52%) have encountered attacks on their devices or accounts. Significant data, such as personal photographs (38%) and passwords (30%), is stored on smartphones, yet only 28% regularly back up important data. Kaspersky recommends integrating cybersecurity into daily routines and has introduced an interactive game, “Case 404,” to educate Gen Z on recognizing digital threats.

Simplify AI agent orchestration with Lakebase Postgres

The auditing process has traditionally been labor-intensive, requiring extensive document reviews. CLA (CliftonLarsonAllen LLP) partnered with the Databricks Forward Deployed Engineering team to develop a document processing application that reduces extraction time from hours to minutes while maintaining quality. The application is built on the Databricks platform, utilizing technologies like Lakebase Postgres, Databricks Apps, Lakeflow Jobs, MLflow, and Unity Catalog Volumes. The application addresses challenges in document parsing, including unpredictable per-task latency, rate-limit-aware throttling, workload prioritization, cost attribution per task, and real-time progress visibility. It eliminates the need for multiple specialized systems by integrating components such as a web application for user interaction, Lakebase for state management, an orchestrator for task management, and AI agents for document processing. The task queue is supported by two Postgres tables in Lakebase, tracking task status and execution attempts. Concurrency safety is ensured through a locking mechanism, and crash recovery is facilitated by lease-based locking. The orchestrator implements rate-limit-aware throttling and idempotent webhook callbacks to manage task processing effectively. An operator dashboard provides real-time metrics on task status, agent performance, and workload costs, with live updates through Postgres LISTEN/NOTIFY events. Cost attribution is managed at the application level, allowing for detailed monitoring of expenditures. Lakebase enhances the orchestration process with features like autoscaling compute, OAuth-rotated authentication, Unity Catalog integration, and support for branching and snapshots.

I Built My Second ETL Pipeline. This Time, I Started Thinking Like a Data Engineer

The author transitioned from a data analyst role to a data engineer, creating a 12-month self-study roadmap focused on learning by building projects. The first project was a GitHub ETL pipeline, which evolved from a simple Python script to a more complex system using SQLite and GitHub Actions for automation. The author realized that the challenges of data engineering lay in system design and orchestration rather than just writing ETL logic. For the second project, the author built an automated RSS ingestion pipeline to explore engineering decisions in creating a reliable data pipeline. The project emphasized the importance of separating application responsibilities from orchestration tasks, leading to the use of Docker for consistent execution environments and Kestra for orchestration. The author validated each component of the project incrementally: first the Python ETL, then PostgreSQL, followed by Docker, and finally Kestra. This approach ensured that each layer functioned correctly before adding complexity. The final architecture included distinct responsibilities for each component: Python for data processing, PostgreSQL for data storage, Docker for execution, and Kestra for orchestration. The author learned that effective engineering involves considering system reliability, error handling, and observability, shifting the focus from merely writing code to designing entire systems. The experience transformed the author's mindset, emphasizing the importance of incremental building and the separation of execution and orchestration responsibilities.
