Dart 3 🎯 Variables, Type Inference (var, final, const), and Compile-time Constants
ByKandZ October 2, 2026October 2, 2026

Dart is a strongly typed language, but you rarely write type annotations explicitly. The compiler infers types from the values you assign. This chapter covers the three ways to declare variables — var, final, and const — and the crucial distinction between values that are computed at runtime and values that are computed at compile…

Docker 3 🐳 Linux Kernel Isolation Mechanics: Namespaces (PID, NET, MNT, IPC, UTS, USER)
ByKandZ October 2, 2026October 2, 2026

Linux namespaces are the kernel feature that makes containers possible. A namespace wraps a global system resource in an abstraction that makes it appear to processes within the namespace that they have their own isolated instance of that resource . Changes made by one process inside a namespace are visible to other processes that are…

ByKandZ August 23, 2025September 19, 2026
