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.

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.

Frustration with Microsoft's data collection practices has increased, particularly since the transition from Windows 7, where the amount of user data collected has significantly risen. Microsoft gathers extensive data points, including device IDs, user IDs, operating system information, and application usage data. Many users are turning to Linux as an alternative, as it respects user privacy and does not collect personal data without consent. Microsoft has also employed manipulative design tactics to influence user behavior, such as persistent prompts and misleading visuals. Additionally, the introduction of ads in Windows 11 has been viewed as disrespectful to paying customers, while Linux remains ad-free. Users are encouraged to switch to Linux to express dissatisfaction with Microsoft's practices and to reclaim their digital autonomy.

Windows 11 is currently operating on 78.8% of Windows devices, while Windows 10 holds a 16.9% share. Microsoft ceased support for Windows 10 on October 14, 2025, making it vulnerable to security threats. Eligible Windows 10 devices can receive Extended Security Updates (ESU) until October 12, 2027, through a paid program, with free ESU available for users in the European Economic Area until October 14, 2026. Approximately 21.4% of devices in small and medium-sized businesses and 16.6% in large organizations still run Windows 10, often due to budget constraints. Devices in industries like healthcare and manufacturing are particularly slow to adopt Windows 11. Windows 10 devices face nearly three times the number of active vulnerabilities compared to Windows 11, with 66.6% rated as high or critical. About 2.8% of Windows 10 systems do not meet the hardware requirements for Windows 11. A total of 18.7% of Windows devices are running unsupported operating systems, with 22.2% on versions that will reach end of support within six months, totaling 40.9% of systems that are unsupported or soon to be. The consumer ESU program will expire on October 12, 2027, after which many devices will transition to unsupported status.

Throttling is the intentional limitation of speed for specific types of traffic, services, protocols, devices, or users. It can occur due to various reasons, such as exceeding data caps, prioritization of certain services, load management during peak hours, or technical policies in networks. Users may experience speed drops that are selective to specific traffic types, indicating potential throttling, while universal slowdowns suggest network overload or outages. Speed tests measure connectivity to specific servers and may not reflect actual download speeds across different paths. Signs of potential throttling include isolated speed drops, consistent slowdowns at specific times, and discrepancies between speed tests and real-world performance. Initial checks should rule out home network issues, and practical diagnostics can help identify throttling by comparing speeds across different servers, types of downloads, and times of day. If throttling is confirmed and support does not resolve the issue, exploring alternative ISPs may be necessary.
