Dux Modular Shell is the modular desktop environment for niri, Hyprland, and Sway that unifies your apps’ theme with the dank16 algorithm. We cover its components, how to try it, and how it differs from GNOME Shell or KDE Plasma.

Feature flags let you turn features on or off without redeploying code. This overview explains how Unleash, the open source platform, implements them with SDKs, activation strategies, and a local setup in minutes.

NTP is the protocol that has kept the clocks of routers, servers, and phones synchronized across the internet since 1985. This guide explains its stratum hierarchy, how the offset is calculated, and how to verify it with chrony on Linux.

The BSD license was born on a tape Bill Joy mailed from Berkeley in 1977. Nearly fifty years later, that same legal permission still lives on in FreeBSD, OpenBSD, and, through Darwin, in macOS.

Every program on your computer believes it has access to all the available RAM, even though that’s physically impossible. Virtual memory is the mechanism that sustains that illusion through paging, page tables, and a special cache called the TLB.

Distributed SQLite combines the SQLite engine with replication across nodes via Raft, WAL streaming, or CRDTs. This guide starts from Philip O’Toole’s twelve-year retrospective to compare rqlite, dqlite, LiteFS, Litestream, and Turso/libSQL, and when each one makes sense.

GNU Taler is the free electronic money protocol that uses bearer tokens to protect buyer privacy. While Taler Operations AG applies to BaFin for a license to operate in Germany, the protocol can already be tested for free in the official demo environment.

TCP congestion control decides, packet by packet, how much each connection can send without saturating the network. This guide explains slow start, CUBIC, and BBR, with real commands to view and change the algorithm on Linux.
