Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

Google boosts AlloyDB vector search with HNSW preview

Google has introduced a preview of its columnar engine-accelerated HNSW feature for AlloyDB, enhancing vector search throughput by up to four times for users of the pgvector extension in PostgreSQL. This improvement is aimed at approximate nearest neighbor searches using HNSW across large datasets. AlloyDB utilizes a columnar engine that allows HNSW indexes to reside in memory, improving throughput and recall metrics. In benchmark tests on the GloVe 100 Angular dataset, queries per second increased by approximately 4.2x to 4.9x, with recall improving from about 0.78 to over 0.94 at a throughput of around 350 queries per second. The columnar engine's design bypasses traditional PostgreSQL buffer management bottlenecks, enhancing efficiency during graph traversal. The memory architecture is distinct from basic caching techniques, and the feature requires no changes to application code. Users must enable the columnar engine and index caching flags to utilize this feature. Benchmarks were conducted on an AlloyDB C4A machine with 16 virtual CPUs.

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.

One in six PCs still run Windows 10, and they’re far less secure than Windows 11

Windows 10 officially reached its end of support in October 2025. Windows 11 has a 78.8% share of Windows devices, while Windows 10 maintains 16.9%. A typical Windows 10 device has an average of 1,903 active Common Vulnerabilities and Exposures (CVEs), compared to 652 on Windows 11, with 66.6% of Windows 10 vulnerabilities rated as high or critical. Microsoft's Extended Security Updates (ESU) program has been extended until October 12, 2027, providing critical security patches for eligible Windows 10 devices. The rise in memory and storage prices has made older Windows 10-compatible hardware more economically viable for some users.

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.
