- Most software engineers lack deep networking knowledge, relying on abstractions.
- Abstractions fail during debugging, leading to blind troubleshooting without underlying knowledge.
- The gap in networking knowledge causes longer debugging, fragile architectures, security issues, and missed performance optimizations.
- Key networking concepts to learn include OSI model layers, IP addressing, TCP/UDP, DNS, and HTTP/HTTPS.
- Practical debugging tools include ping, traceroute, dig, curl, netstat, ss, and tcpdump.
- Understanding distributed systems patterns like timeouts, retries, circuit breakers, and load balancing is crucial.
- Resources for learning include textbooks, zines, guides, and cloud provider documentation.
- Engineers with networking knowledge debug faster, design resilient systems, and have a competitive edge.
