5 Windows terminal tricks I use to improve my productivity

Windows Terminal is a productivity tool in Windows 11 that allows users to manage multiple profiles, such as Windows PowerShell and Linux distributions, within the same window. Users can rename and recolor tabs for easier navigation. The Command Palette, activated by Ctrl+Shift+P, provides a searchable interface for commands, simplifying execution without needing to memorize shortcuts. Focus mode hides the title bar and tabs for distraction-free use and can be set as the default launch option. The split pane feature enables users to display multiple profiles simultaneously, enhancing multitasking. Quake mode keeps the terminal visible at the top of the screen, minimizing distractions and allowing easy access to other applications.

Migrate Google Cloud SQL for PostgreSQL to Amazon RDS and Amazon Aurora using pglogical

PostgreSQL is a popular open-source relational database used by enterprise developers and startups, enabling rapid prototyping and supporting mission-critical applications. Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition facilitate easy setup, operation, and scaling of PostgreSQL deployments in the AWS Cloud, automating administrative tasks like software installation, storage management, and backups. The pglogical extension, compatible with PostgreSQL versions 9.4 and higher, allows for asynchronous replication and is supported on RDS for PostgreSQL and Aurora PostgreSQL from version 12. It uses a publisher/subscriber model for logical streaming replication. To migrate a PostgreSQL database from Google Cloud SQL to RDS for PostgreSQL or Aurora PostgreSQL, users must configure the primary database in Cloud SQL, create a PostgreSQL user with replication privileges, enable logical replication parameters, and create the pglogical extension. The RDS instance also requires a special user for replication, enabling logical replication parameters and creating the pglogical extension. Known limitations of pglogical include the inability to replicate primary key changes directly, the need to manually transfer extensions, and the lack of support for materialized views and large objects. Workarounds involve using surrogate keys for primary keys, manually creating extensions, and converting large objects to bytea columns or storing them in Amazon S3. DDL statements are not automatically replicated, but can be queued using the pglogical.replicate_ddl_command function.

Facebook, Yandex Apps Secretly Track Users Via Hidden Ports, Research Claims

Recent findings from IMDEA Networks Institute indicate that Facebook and Instagram apps have been tracking Android users' web browsing activities without consent, bypassing privacy controls and functioning even in incognito mode. This tracking affects millions of websites using Meta's tracking code. Yandex has employed similar tracking techniques since 2017, creating a cross-platform surveillance network. The tracking exploits Android’s permission system by establishing background services that listen on network ports, allowing the apps to capture browsing data and associate it with users' accounts. Meta's pixel is present on about 5.8 million websites, while Yandex Metrica is on around 3 million sites, potentially impacting billions of users. Approximately 78% of sites with Meta’s pixel and 84% of Yandex's sites attempted localhost communications without user consent. This tracking method operates at the operating system level, unaffected by cookie clearing, incognito modes, or privacy settings. Researchers have demonstrated that malicious apps could exploit this technique to gather users' browsing histories. Many website operators were unaware of these localhost communications, leading to confusion and complaints. In response, major browser vendors are implementing measures to block these tracking methods. Meta ceased this tracking on June 3rd, coinciding with the research's public release. The research highlights a significant security gap in mobile platforms regarding localhost communications, emphasizing the need for stricter policies and vetting processes.

Supercharging vector search performance and relevance with pgvector 0.8.0 on Amazon Aurora PostgreSQL

The Amazon Aurora PostgreSQL-Compatible Edition has integrated support for pgvector 0.8.0, enhancing vector search capabilities significantly. This version achieves up to 9x faster query processing and delivers 100x more relevant search results compared to previous iterations. Key improvements in pgvector 0.8.0 include: - Up to 5.7x improvement in query performance for specific patterns. - Introduction of the iterative_scan feature, enhancing recall for filter queries requiring approximate nearest neighbor (ANN) index searches. - Improved cost estimation for more efficient query planning, allowing the selection of traditional indexes for complex filtered searches. - Flexible performance tuning with two modes for iterative_scan: relaxed_order and strict_order. Previous versions faced challenges with overfiltering, where combining vector similarity search with traditional SQL filters resulted in fewer results than expected. The HNSW indexing algorithm accelerates vector similarity searches by creating a multi-layered graph structure for efficient navigation. Iterative index scans in pgvector 0.8.0 improve query reliability and performance by applying filters during the scanning process, reducing false negatives and enhancing performance. The configuration options for iterative scanning include off, strict_order, and relaxed_order, with relaxed_order providing the best balance between performance and accuracy. In performance tests, pgvector 0.8.0 demonstrated substantial improvements across various query patterns, with significant enhancements in result completeness and recall. The database can now efficiently handle enterprise-scale applications, such as e-commerce and recommendation systems, with high performance and result quality even as product catalogs expand. Best practices for deploying pgvector 0.8.0 include using HNSW with recommended parameters, creating additional indexes on commonly filtered metadata columns, and tuning query parameters based on specific use cases. Operational best practices involve using Graviton4-based instances for optimal performance, monitoring and tuning slow vector queries, and considering partitioning for very large tables.

New Malware Compromise Microsoft Windows Without PE Header

A new strain of malware has been operating undetected on Windows systems for several weeks, utilizing advanced evasion techniques that corrupt its Portable Executable (PE) headers to avoid detection. Security researchers discovered this malware embedded in the memory of a compromised system during an investigation, using a 33GB memory dump that revealed its presence in a dllhost.exe process with process ID 8200. The malware, classified as a Remote Access Trojan (RAT) by Fortinet, employs batch scripts and PowerShell commands for its attack and has capabilities for screenshot capture, remote server functionality, and system service manipulation. Its command and control infrastructure uses encrypted communications, complicating detection efforts. The malware's distinctive feature is the deliberate corruption of DOS and PE headers, which hinders reverse engineering and complicates the reconstruction of the executable from memory dumps. Researchers had to manually locate the malware’s entry point and resolve complex import tables for it to function in a controlled environment.
