In this episode, Lucas and Luna dive into Linux uprobes — user-space probes that let engineers trace application code at runtime without recompiling. They explore how uprobes work alongside kprobes, why companies like Netflix use them to debug latency in production microservices, and a concrete example using bpftrace to trace malloc calls in a containerized app. By the end, you'll understand why uprobes are a lightweight alternative to traditional debuggers and how they enable observability in modern distributed systems. This episode is recorded on July 3, 2026, and references real-world use cases from the Linux kernel community. #Linux #Uprobes #UserSpaceProbes #KernelTracing #Observability #BPFtrace #Netflix #PerformanceDebugging #ProductionTracing #Microservices #Technology #OpenSource #LinuxKernel #DynamicTracing #Kprobes #FexingoBusiness #BusinessPodcast #TheLinuxPodcast Keep every episode free: buymeacoffee.com/fexingo
