Why i3wm The i3 window manager (i3wm) is a tiling window manager focused on efficiency and productivity. It was first developed in 2009 by German developer Michael Stapelberg to address the limitations of the wmii window manager. The name “i3” stands for “improved tiling wm.” Written in C with roughly 10,000 lines of concise code, i3 is lightweight while still offering powerful functionality. It has become popular among developers, system administrators, and power users who prefer keyboard-driven workflows with minimal mouse use. It is especially common among users of distributions such as Arch Linux, Gentoo, and NixOS. ...

When memory runs low, Linux pushes rarely used pages out to swap. The problem is that swap usually lives on disk. The moment disk swap gets busy, the system noticeably stutters. zram puts that swap in compressed RAM instead of on disk: rather than writing pages to disk, it compresses and keeps them in RAM. The trade is simple. You spend a little extra CPU compressing and decompressing, and in return you turn disk I/O into RAM access. Text-like data typically compresses 2:1 to 4:1, so you get back the physical RAM that pages would have consumed, at less than half the cost. ...

A static IP address is an IP address manually specified by a network administrator instead of being dynamically assigned from a DHCP server. It is essential in environments where the IP address must not change, such as server operation, remote access, and network service hosting. Ubuntu 24.04 LTS uses Netplan as the default network configuration tool and also supports nmcli and nmtui interfaces through NetworkManager, allowing users to configure networks in their preferred way. ...
