TecMint

A new tutorial on TecMint walks Linux administrators through five commands to prevent the kernel's out-of-memory killer from terminating critical applications. The OOM Killer automatically kills processes when system memory runs out, which can take down important services unexpectedly. The guide explains how to adjust each process's oom_score_adj setting so essential apps are spared while memory pressure is handled elsewhere.

A new comparison from TecMint examines Podman versus Docker Engine, arguing that teams increasingly pick Podman for its rootless container architecture. Rootless operation removes the need for daemon privileges, improving security by letting containers run under ordinary user accounts. The piece walks through differences in architecture, security and everyday use for developers choosing between the two container tools.
