Ever wonder why opening a new database connection for every API request crashes servers? Discover connection pooling—the backend pattern that keeps apps fast and scalable.

Posted by Daniel Owens via Fulldisclosure on Nov 04The unixODBC driver manager library contains multiple races of importance / interest, including a set of data races in the connection-pooling configuration state data that can cause one thread to read a half-written pool-size or timeout value, which can lead to a variety of harmful effects, as well as a race between teardown and error-handling functionality that can result in double-frees and use-after-frees. Other races exist within the...

Serverless architectures promise infinite scale, but traffic spikes often expose hidden performance bottlenecks like Lambda cold starts and DynamoDB throttling errors. This deep-dive guide explores advanced optimization techniques—including Graviton2 migration, package size reduction, global connection pooling, and precision-tuned provisioned capacity. Learn how top cloud engineers eliminate latency spikes and build lightning-fast, high-throughput serverless applications on AWS.

Azure SQL Hyperscale brings modern cloud and AI capabilities directly into SQL based applications. In this developer focused session, you’ll learn how Hyperscale’s architecture enables elastic scale, predictable performance, and cost efficient operation while remaining fully SQL Server compatible. We’ll cover building APIs with JSON, exposing data through REST style access, using vectors for AI driven search, and integrating AI agents via SQL MCP—showing how Hyperscale supports modern app and AI workflows without introducing new databases or abandoning the SQL Server you know and love.

Prisma P1001 on Vercel means Prisma cannot reach Postgres. Check DATABASE_URL, host, port, pooling, and preview variables with this fix guide.

Learn how to connect databases to Express.js applications, when to use an ORM, and best practices for connection pooling, security, and error handling.

A new meta-analysis pooling data from more than 12,000 adults has found that difficulties with managing emotions are notably linked to one form of narcissism while showing little to no connection with another. The study, published in Personality and Individual Differences, indicates that insecure and defensive features of narcissism are associated with emotion dysregulation, whereas more boastful, outwardly dominant narcissistic traits are not consistently tied to these emotional difficulties.
