What is Tetragon, how it works, and how to use it to detect and react to security-significant events in your Kubernetes, Docker, or plain Linux environment.

Learn how Inspektor Gadget pairs eBPF with WASM to process kernel events—and walk through the same idea yourself by implementing a minimal example.

This lab teaches you how to use eBPF socket acceleration to speed up communication between processes on localhost and optimize a transparent Envoy proxy setup. You will implement techniques that bypass parts of the kernel networking stack, allowing data to be transferred more directly between sockets to improve throughput and reduce latency.

3-phase AWK challenge on realistic data in /home/laborant/awk_challenge/. Fundamentals: columns, delimiters, formatting. Logic & regex: filters, anchors, conditions, math. Sysadmin: logs, CSVs, metrics, counts, reports. Data lives under /home/laborant/awk_challenge/ (logs/access, data/hr, sys/metrics) and outputs are written to /home/laborant/ files.
A hands-on guide to building a minimal service mesh using eBPF and Envoy, focusing on transparent traffic interception and the core mechanics behind policy, observability, and encryption.
A 3-in-1 playground (Kubernetes, Docker, and vanilla Linux hosts) to experiment with Tetragon - an eBPF-powered security observability tool.
Explore live host CPU/Memory/Disk/Network telemetry as an interactive Doom diagnostics lab. All the elements in the game react to system signals (eg, the cpu cores glow red when there's high utilization).
