Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
eBPF XDP (eXpress Data Path) Line-Rate Packet Filtering: Dropping Volumetric DDoS & Malicious Scanners at the NIC Ring Buffer
Standard iptables and nftables choke under multi-gigabit SYN floods and brute-force scans. Harness eBPF XDP programs to inspect and discard packets directly at the network card driver before OS kernel allocation.
eBPF-Powered Kernel Observability: Profiling Socket Drops, TCP Retransmits, and TLS Handshake Latency in Linux
Intermittent 502/504 errors between edge proxies and backend microservices often remain invisible in APM logs. Learn how eBPF kernel probes trace TCP backlog overflows and socket drops with zero application overhead.
