In a previous post, Automatic Enum Stringification in C via Build-Time Code Generation, I described how to extract enum labels and values directly from DWARF debug information at build time. enum color { C_NONE, C_RED, C_YELLOW, C_GREEN } ; // Request enum descriptor for e_color ENUM_DESCRIBE(e_color, enum color) void foo(enum color c) { printf("Color=%s(%d)\n", ENUM_LABEL_OF(e_color, c), c)

This isn't an anti-Go post. Go is a great language. This is about what I want to understand. I just finished building an L7 HTTP load balancer in Go. It accepts connections. It parses HTTP headers. It forwards requests to backend servers using round-robin. It handles concurrent connections with goroutines. It has health checks. It works.

Most developers use malloc without thinking much about what happens underneath. This project is an attempt to explore that layer by building a memory allocator from scratch in C. The allocator implements malloc, free, calloc, and realloc without relying on libc’s heap functions. It focuses on: Thread safety Per-thread caching (tcache) Efficient free block management using bins mmap-based memory g
Power BI is a powerful business analytics service developed by Microsoft that empowers users to visualise data and share interactive dashboards across their organisation. While Power BI can handle data from various sources, its true potential is unleashed when connected to robust data sources like SQL databases. SQL databases—such as PostgreSQL, MySQL, and SQL Server—are the industry standard for
