When running a Gentoo Linux system in a restricted network environment, routing package downloads and repository synchronization through a proxy is sometimes necessary. Here is how to configure emerge to use HTTP or SOCKS proxies. Adding the proxy to make

Emacs can slow down when opening files with exceptionally long lines, such as minified JavaScript or CSS, SQL dumps, or large JSON files. One solution to prevent these files from slowing down Emacs is to use the built-in global-so-long-mode (or so-long-mo

Emacs terminal buffers like eat, vterm, ghostel, term, and ansi-term can become slow when processing large volumes of standard output. Watching Emacs freeze while a build script dumps thousands of lines is frustrating, but terminal latency is not an unavo

The display-line-numbers-mode and global-display-line-numbers-mode modes render line numbers in the margin of an Emacs window. Line-number display is implemented in the core C display engine, avoiding the performance cost of legacy Elisp overlays like lin

The consult Emacs package provides asynchronous search commands such as consult-fd, consult-find, consult-grep, consult-git-grep, and consult-ripgrep. For these commands, Consult does not necessarily start a new search for every change to the minibuffer i

As an Emacs user, your configuration can easily grow from a few lightweight adjustments to a massive, hundred-package IDE. Without careful management, Emacs startup time can degrade from sub-second execution to several seconds, or minutes, in the worst ca

Emacs ships with default settings intended for backward compatibility and convenience over strict security. The following settings enforce TLS certificate verification, reduce unintended ffap network lookups, restrict the evaluation of potentially unsafe

Emacs automatically applies project-specific configurations through file-local and directory-local (.dir-locals.el) variables when opening a file or directory. While this feature ensures consistent settings across environments, it can cause security risks

This article presents a set of Emacs Dired configuration changes to enhance file management. The configurations sort directories before files for easier navigation, hide dotfiles, reduce unnecessary confirmation prompts, prevent UI lockups caused by netwo

As an Emacs configuration grows, startup time can gradually increase. Measuring that increase accurately makes it easier to identify regressions. The majority of Emacs users use emacs-init-time. However, this built-in function does not measure all the wor
