PostgreSQL vs. MySQL in 2025: Choosing the Best Database for Your Backend

In 2025, PostgreSQL has a usage rate of 45.55%, while MySQL has a usage rate of 41.09%. PostgreSQL is preferred for applications requiring complex queries and robust data management, while MySQL is favored for speed and efficiency in read-heavy environments. PostgreSQL was named DBMS of the Year 2023 for the fourth time since 2017, with its latest version released in September 2023 featuring performance and replication enhancements. Developer surveys show PostgreSQL adoption has increased from 33% in 2018 to nearly 50%. MySQL is recognized for its rapid performance and ease of implementation, particularly in e-commerce and content management systems. Performance tests indicate PostgreSQL is approximately 1.6 times faster than MySQL in complex query scenarios. PostgreSQL offers built-in row-level security and encryption, while MySQL provides a user-friendly interface and solid security measures. PostgreSQL excels in managing large datasets and complex operations, whereas MySQL uses a distributed systems approach for workload management.

‘These kids do not care about romance’: Game devs want to know what today’s teens want, and surveys say sex and romance isn’t it

Surveys indicate that today's youth prefer narratives focused on platonic friendships and social connections over romance and sexual themes. At the D.I.C.E. Summit, industry leaders shared that 73% of individuals aged 16 to 24 report feelings of loneliness, attributed to various factors including global events and social media. Research from UCLA shows young people value safety, kindness, acceptance, friendship, and spiritual connection, with a growing disinterest in romance. The 2024 Teens and Screens report reveals that "romance and/or sex" ranked 15th out of 21 media preferences among adolescents, while "friendships and social groups" ranked 5th. The desire for content focused on platonic relationships rose from 51.5% in 2023 to 63.5% in 2024, and the belief that sexual content is not essential to advance a plot increased from 47.5% to 62.4%. Additionally, adolescents are engaging in sexual activity less frequently than previous generations. Mainstream video games have historically featured minimal sexual and romantic content, with recent titles like Baldur's Gate 3 exploring these themes more deeply.

Multi-tenant vector search with Amazon Aurora PostgreSQL and Amazon Bedrock Knowledge Bases

The article discusses the implementation of a multi-tenant vector store using Amazon Aurora PostgreSQL-Compatible Edition and Amazon Bedrock Knowledge Bases. It outlines a scenario where users request home surveys, and surveyors update findings stored in an Amazon S3 bucket. The process involves converting documents into vector embeddings for enhanced natural language queries through the Retrieval Augmented Generation (RAG) technique. Key steps include: 1. Ingesting data from S3 into Amazon Bedrock Knowledge Bases. 2. Using an embeddings model to convert documents into vector embeddings. 3. Storing vector embeddings, data chunks, and metadata in Aurora with pgvector. 4. Submitting natural language queries that are transformed into embeddings for retrieval from the vector store. 5. Forwarding relevant documents to a large language model for response generation. To set up the vector store, prerequisites include access to an Amazon Aurora PostgreSQL-compatible database, Amazon S3 for document storage, and Amazon Bedrock for managing knowledge bases. The article provides SQL commands for creating the necessary schema, vector table, and index in Aurora, as well as instructions for ingesting data and ensuring multi-tenant data isolation through metadata filtering. Best practices for deploying a multi-tenant vector store include optimizing chunk size, evaluating embedding models, and monitoring query performance. The article emphasizes the benefits of fully managed solutions to reduce operational complexity.

Google Opinion Rewards wants you to share even more data to get more surveys (APK teardown)

Google Opinion Rewards may increase the number of surveys available to users who opt for personalized ads. The app rewards users with Google Play credits for completing surveys and has relied on location history for tailoring questions. The latest version of the app includes a feature called Enable Personalized Ads, which encourages users to share more personal data in exchange for additional survey opportunities. Users can review their data in the Google Ad Center after activating this setting. Opting into personalized ads may lead to more frequent surveys, potentially increasing earnings from the app. However, the relationship between personalized ads and survey frequency is unclear, as personalizing content may sometimes reduce available surveys. Users must consider the trade-offs between data sharing and potential rewards.
