Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

I finally found out what Windows does during “Getting things ready” — and I’m no longer annoyed

Windows Patch Tuesdays often lead to uncertainty for users due to the "Getting things ready" screen, which lacks a percentage bar or estimated time of completion. During this time, Windows is performing complex tasks managed by the Update Orchestrator, which assesses applicable components of updates, prepares necessary files, and stages them for installation. The servicing stack, including Component-Based Servicing (CBS), ensures that only relevant parts of an update are applied at the component level. The update process involves checks, package handling, staging, installation, and finalization, influenced by each PC's unique configuration, installed components, optional features, and drivers. The variability in wait times is due to these factors, and while Microsoft does not provide precise completion times, clearer messaging about the current task could improve user experience. The lack of information can create confusion between necessary updates and a system that appears stuck.

Enable BitLocker on Windows 11: 11 Steps, 45 Min [2026]

A stolen laptop can lead to a significant data breach, particularly when taken from public places. Windows 11 has introduced BitLocker, a full-disk encryption feature that became mandatory for Australian businesses in 2026. The Office of the Australian Information Commissioner reported 766 notifiable data breaches in the latter half of 2024, with unauthorized access to devices being a major cause. Full-disk encryption is crucial for compliance with the Essential Eight framework, which mandates data protection on portable devices. BitLocker ensures that data on an encrypted drive becomes unreadable if the drive is removed and connected to another computer. It aligns with the Essential Eight framework, requiring evidence of encryption rather than just claims of protection. There are three types of encryption on Windows 11: Device Encryption, BitLocker Drive Encryption, and File-Level Encryption. BitLocker is available only on Windows 11 Pro and higher editions. To use BitLocker, certain prerequisites must be met, including having Windows 11 Pro or higher, a Trusted Platform Module (TPM) 2.0, UEFI firmware with Secure Boot enabled, and local administrator rights. The process to enable BitLocker involves confirming the edition, checking TPM status, enabling BitLocker through Windows Settings or PowerShell, and backing up the recovery key. Organizations can deploy BitLocker fleet-wide using Microsoft Intune, and additional security measures like TPM+PIN can be implemented for pre-boot authentication. Common pitfalls during BitLocker rollout include skipping recovery key backup and assuming that Home edition machines are covered. Troubleshooting common BitLocker issues involves identifying symptoms and applying appropriate fixes. Advanced tips for enhancing security include suspending BitLocker before maintenance and auditing compliance at the fleet level. BitLocker is integral to protecting data on portable devices, and compliance documentation is essential for proving that every device has an active recovery key.

Running pgvector in production on Amazon Aurora PostgreSQL

Running pgvector on Amazon Aurora PostgreSQL-Compatible Edition offers a vector store with operational capabilities, high availability, and scalability. It is favored for Retrieval Augmented Generation (RAG) workloads transitioning to production, but increased traffic introduces challenges like query latency and memory management. Key operational practices for pgvector workloads include selecting the appropriate index type (HNSW or IVFFlat), establishing a baseline schema, choosing a suitable distance operator, scaling the index through quantization and partitioning, and preparing for churn and observability. The prerequisites for using pgvector include an Aurora PostgreSQL-Compatible cluster with specific PostgreSQL versions and the vector extension enabled. The embedding model used in examples is Amazon Titan Text Embeddings V2, which produces 1024-dimensional embeddings. pgvector supports two Approximate Nearest Neighbor (ANN) index types: HNSW, which is efficient for querying and allows for incremental insertions, and IVFFlat, which is less resource-intensive but requires rebuilding if data changes. There are scenarios where forgoing an index is beneficial, such as small datasets or partitioned datasets requiring 100% recall. A baseline schema for a multi-tenant document store includes creating a table for documents with an embedding vector and establishing indexes for tenant IDs and embeddings using HNSW. The recommended parameters for HNSW include m = 16 and ef_construction = 128. Scaling to millions of vectors involves quantization, tuning HNSW parameters, and partitioning. Aurora Optimized Reads can extend effective cache capacity, and managing index churn is crucial for maintaining performance. Observability metrics include query-level statistics, instance-level metrics, and custom application-defined metrics. To clean up after testing, it is advisable to drop the created indexes and tables, and delete the Aurora PostgreSQL-Compatible cluster and any manual snapshots taken during testing.
