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.

St. Louis Restaurant Review has launched a dedicated Android mobile application available on the Google Play Store, providing St. Louis diners with access to restaurant news, reviews, and an online ordering process through eOrderSTL. The app offers real-time updates on restaurant openings and closures, detailed reviews focused on the local culinary scene, and integrates eOrderSTL to allow users to order food directly from the app. This integration helps restaurant owners avoid high commission fees charged by national delivery platforms, retain customer data, and maintain control over their digital storefronts. Consumers benefit from lower menu prices, support for the local economy, and a streamlined ordering experience. The app is designed for speed and ease of use, enhancing the dining experience for locals.

North Korea's Contagious Interview hackers have been using a deceptive strategy to target developers by posing as recruiters and embedding malware in SVG files. Elastic Security Labs discovered that the attackers hid malicious payloads within HTML comment blocks of these files, allowing the malware to evade antivirus detection. At the time of the findings, no antivirus engines flagged the compromised repositories, which included trojanized GitHub repositories disguised as coding challenges. The malware executed automatically at server startup and deployed four modules: a browser credential and cryptocurrency wallet stealer, a file stealer, a remote access Trojan, and a clipboard monitor. The campaign, tracked as REF9403, is part of the ongoing Contagious Interview operation attributed to North Korea's Lazarus Group, which aims to generate revenue through cryptocurrency theft. Developers are advised to audit any projects run from unsolicited sources and to monitor specific domains associated with the attack.

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.
