Developer Open-Sources Go-Based MCP Server to Connect AI Assistants to PostgreSQL

·1 views

Developer Akshay Gupta has open-sourced a Go-based MCP server that allows AI coding tools like Claude Code and Cursor to connect directly to a live PostgreSQL database, eliminating the manual copy-paste workflow common in AI-assisted database tasks. The server exposes nine tools, including schema introspection, query execution, EXPLAIN ANALYZE, slow query analysis, and an index advisor powered by HypoPG. Built as a single ~15 MB static binary, it requires no Python runtime and ships with Docker support for straightforward setup. A restricted mode enforces read-only transactions at the Postgres level, ensuring write protection without relying on query text filtering. The project is available on GitHub at github.com/gupta-akshay/postgres-mcp, with full setup instructions, Docker configuration, and a test suite requiring at least 95% code coverage in CI.

Fix Kotlin null assertion errors in Jackson by enabling NullIsSameAsDefault

Developers using Jackson to deserialize Kotlin data classes with empty lists may encounter unexpected null assertion errors. The issue arises when a field like a List is annotated with a default empty value but the incoming payload contains an empty list, causing Jackson to treat it as null. A reliable fix in Jackson 2.17 involves manually building the KotlinModule with the NullIsSameAsDefault feature enabled, rather than using the standard registerKotlinModule() shortcut. This configuration ensures that null values from the payload are treated as equivalent to the declared default, preventing runtime errors. The solution requires the jackson-module-kotlin dependency at version 2.17 or higher.

A Philosophical Look at 250 Years of American Innovation and Breakthroughs

A reflective essay published on DEV Community examines the United States on its 250th anniversary, tracing the philosophical and structural forces behind its history of breakthroughs. The piece argues that geography, migration, and infrastructure — from the Erie Canal to the transcontinental railroad — laid the foundation for America's rapid rise as a continental power. It draws a sweeping arc from prehistoric mass extinction events through European colonization, westward expansion, and industrialization, to the Space Race and modern technology. The author deliberately avoids naming historical figures, framing progress as a collective flow of opportunity rather than individual achievement. The essay closes with a nod to the Moon Landing and the current AI era as the latest chapters in an ongoing story of transformation.

How GCC Turns C Source Code into a Runnable Binary: A Step-by-Step Breakdown

GCC (GNU Compiler Collection) is not a single tool but a multi-stage pipeline that transforms human-readable C code into machine-executable binary instructions. The process moves sequentially through preprocessing, compilation to assembly, assembly to object files, and finally linking against system libraries such as libc. The resulting binary is an ELF file containing sections like .text for executable code, .plt for dynamic library resolution, and .init/.fini for setup and teardown routines. GCC also injects several functions the programmer never wrote, including _start, which serves as the true entry point called by the OS kernel before main is ever reached. When a program is launched, the Linux kernel loads the binary, hands control to the dynamic linker, and triggers this chain of compiler-generated functions before and after the user's main function executes.

How to Copy Files from a Docker Container to Your Host Machine

Developers sometimes need to access files generated inside a Docker container directly on their host machine. The process begins by using 'docker exec' with '/bin/bash' to enter the container and verify the target files exist, as bash offers more features than sh. Once confirmed, the 'docker cp' command is used with the syntax 'sudo docker cp -a <container_id>:<container_path> <host_path>' to transfer files. The '-a' flag enables archive mode, which preserves GID and UID metadata during the copy operation.
