Programming Languages

Bash and shell scripting are essential tools for automating tasks, managing systems, and orchestrating build pipelines in Unix-like environments. Despite their ubiquity, shell scripts can exhibit difficult-to-debug behaviors such as silent failures, unexpected variable expansions, permission issues, race conditions, and portability challenges across environments. This article presents a deep dive into advanced Bash troubleshooting techniques to diagnose, fix, and future-proof critical automation scripts in production systems.

Erlang is a concurrent, fault-tolerant functional programming language widely used in telecom, messaging systems, and scalable distributed applications. With its actor-based concurrency model and robust OTP (Open Telecom Platform) libraries, Erlang excels in systems requiring high availability. However, developers often encounter challenges such as process crashes, message queue overflows, distributed node connection issues, hot code upgrades failing silently, and debugging performance bottlenecks in large-scale deployments. This article offers a deep troubleshooting guide for addressing advanced Erlang issues in production systems.
