REA's hexagonal architecture unifies 3 RE engines behind 128 tool contracts, processing 262K+ lines of TypeScript with an Evidence-First design that makes every AI-driven conclusion verifiable.
Manual OS installation takes 30-60 min per server. PXE+Kickstart+Cloud-init reduces this to 5-15 min unattended. Learn to build automated bare metal provisioning.
AppArmor's unprivileged_userns strips sys_admin from Electron's GPU process on Ubuntu 24.04, causing misleading Permission denied errors. Here is the fix.
MAAS has 499 GitHub stars, Tinkerbell 989, Ironic 564, Foreman 2,900. Compare the four bare metal orchestration engines to find your best fit.
Only 24% of IT leaders trust their CMDB data. 30% of data center servers are comatose. This guide shows how automated discovery achieves 87% CMDB accuracy.
Bare metal cloud: $14.32B in 2025 at 20.7% CAGR. Covers CMDB automation, provisioning engines (MAAS/Tinkerbell/Ironic), multi-AZ architecture, self-service.
Unix domain sockets can form reference cycles (A→B→C→A). The kernel performs mark-and-sweep GC to detect and reclaim unreachable socket cycles. Source analysis reveals the algorithm.
System V message queues are not slow legacy tech. The kernel uses READ_ONCE(r_msg) for lock-free receive, and MSG_BARRIER avoids taking the queue lock. Source analysis reveals the optimization.
pipe() is not just a kernel buffer. It uses a circular ring of page-sized buffers with head/tail indices. Page stealing enables zero-copy splice(). Source analysis reveals the mechanism.
Shared memory is not direct physical memory access. System V SHM is implemented on top of tmpfs — shmget() creates a tmpfs file, shmat() mmap()s it. Source analysis reveals the implementation.
