GitHub will reject command-line support bundle uploads from outdated versions of GitHub Enterprise Server lacking security patches starting August 18, 2026. The npm package @copilot-mcp/apex has been identified as a post-install dropper that installs a macOS infostealer, phishing for sensitive information and maintaining a connection to an attacker's server. A rogue extension on the Microsoft Visual Studio Code marketplace, "Markdown All Pro," impersonates a legitimate tool and opens a backdoor after installation. A phishing campaign targeting Portuguese users delivers the Lampion banking malware, which has been active since 2019. DoubleVerify reports a rise in "AfterCall" apps that exploit user permissions for ad fraud. The GhostCommit attack method hides malicious instructions within PNG images in pull requests. The U.S. government has updated its advisory on Iranian-affiliated cyber activity targeting operational technology devices. An Android app posing as a civil defense alert system has been found to contain malware for data harvesting. An Iranian threat actor is distributing MarkiRAT malware through fake applications. An analysis of 28 AI-coded applications revealed 434 vulnerabilities, prompting Cisco to introduce Antares to identify vulnerabilities in codebases. A Russian-speaking threat actor is dismantling guardrails on AI models to create offensive tools.

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.

Bethesda's space RPG, Starfield, faces challenges due to frequent loading screens that disrupt the gameplay experience. A mod called Seamless Planet Takeoffs aims to enhance the takeoff experience by allowing players to remain in the cockpit during launch, providing a more immersive transition. The mod is still in beta and does not completely eliminate loading screens but improves the experience by masking transitions. The creator, 0xBobby, notes that while the mod enhances takeoff fluidity based on atmospheric conditions, seamless landings remain difficult to achieve and may not be possible.

Activision has announced the beta schedule for Modern Warfare 4, with two beta weekends planned. The first weekend, from August 21-25, is exclusive to pre-order customers on PC, PS5, and Xbox, while the second weekend, from August 28 to September 1, is an open public beta available on all platforms, including the Switch 2. Participants will have the opportunity to unlock 19 weapons and engage in various combat scenarios, including 3v3 skirmishes and larger battles with vehicles. Players can test new and returning game modes, such as Search & Destroy and Kill Block, as well as a Training Mobility Course. The full game is set to release in late October.

GOG specializes in reviving classic games for modern PCs and promoting DRM-free gaming. The company recently commented on Sony's plan to stop producing game discs by 2028, highlighting that users can download offline installers of their games from GOG, save them to a disc, and own them permanently without needing permission from a storefront. Although many modern PCs lack optical drives, GOG's installers provide a solution for users. The process of creating personal game discs involves downloading backup installers from GOG's game pages and burning them onto a disc. Users can also combine multiple games onto a single disc. YouTuber Archades Games offers a guide on advanced techniques for this DIY approach.

Chris Livingston is exploring job simulations to find a new career and is currently engaged in a Forensics: Crime Scene Detective simulation. His understanding of crime scene investigations is influenced by media portrayals, particularly CSI: Miami. In his first case, he successfully solves a bullet-in-wall scenario, scoring 100% after several attempts. However, he struggles with a coin burglary case, ultimately scoring only 16 out of 100 due to missed evidence and failed analyses. He reflects on whether he would enjoy being a real-life crime scene detective, finding the documentation appealing but the reality of blood and violence unappealing. Livingston appreciates the game's approach to failure, which allows for learning from mistakes.

Serverless PostgreSQL is a fully managed cloud database model that separates compute and storage, allowing them to scale independently and automatically based on demand. It eliminates the need for manual infrastructure provisioning and capacity planning, charging only for active usage. Unlike traditional PostgreSQL setups, which require continuous resource allocation and manual scaling, serverless PostgreSQL provisions resources on demand and can scale down to zero during idle periods. Serverless PostgreSQL integrates with serverless compute platforms, enabling analytical queries to access the same data within a unified architecture. Key differences between traditional and serverless PostgreSQL include manual versus automatic provisioning and scaling, fixed versus usage-based billing, and high versus reduced operational overhead. Lakebase architecture is an emerging model that combines transactional databases with lakehouse foundations, allowing operational and analytical workloads to coexist on a single platform. This architecture minimizes data duplication and simplifies access, enhancing data management and analysis. Serverless PostgreSQL operates on a cloud-native architecture that enhances efficiency by allowing compute and storage to scale autonomously. It features scale-to-zero behavior, where compute resources are suspended when inactive and reactivated upon new queries. Major providers include Databricks Lakebase, Amazon Aurora Serverless v2, and Neon, each offering varying capabilities and integrations. Pricing for serverless PostgreSQL typically includes charges for compute resources, storage, and data transfer, with costs fluctuating based on workload activity. Cold start latency is a performance consideration, as reactivating compute resources can introduce delays. Strategies to mitigate this include keeping resources partially active or selecting providers with minimal cold start impacts. Serverless PostgreSQL is well-suited for OLTP workloads, while lakebase architecture is better for AI development, variable workloads, and environments requiring rapid iteration. Setting up serverless PostgreSQL involves choosing a provider, creating a database instance, and configuring access settings. It can also be used alongside serverless compute platforms for analytics, further extending its capabilities.
