Emacs is a family of text editors that is extensible, customizable, self-documenting and has real-time display. It was written in Lisp by Richard Stallman under the GNU license. Emacs can be used for text editing, coding, debugging, file management, calendars, tasks, email and web browsing. It allows users to customize it in any way and develop new features through Emacs Lisp. Emacs is lightweight, acts as an integrated platform for general purposes using text files as its universal data structure, and is keyboard-driven.

The story of Emacs
Emacs is a family of text editors, described as “the extensible,
customizable, self-documenting, real-time display editor.”
It is written in Lisp by Richard Stallman and under GNU
License

What are Emacs for?

Text editing
Coding & Debugging
File Management
Calendar, tasks management
Email reading, web surﬁng
etc
You can
(1) customize Emacs in anyway you want;
(2) develop more features by writing code in Emacs Lisp

Trang-Khon Trieu Introduction to Emacs 2012-10-29 Mon 3 / 11

Why Emacs?

lightweight editor (in comparison to Eclipse, NetBean)
an integrated platform for general purposes (email, web,
coding, etc)
data in the form of text ﬁles
universal data structure, not locked in any speciﬁc format (XML,
HTML, etc), thus technology-independent
automating by scripts (accumulation over time)
searchable by any search engine (Google Desktop, Recoll, etc)
keyboard-driven
faster than mouse-driven
muscle memory (subconscious)

Concepts

Control key vs. Meta key
Buﬀer vs. Windows
Major mode vs. Minor mode
Major modes: ruby mode, java mode, dired mode, org-mode,
etc.
Minor mode: show line number, scrollbar, status info, etc.

This document provides 7 steps for setting up online hosting and FTP for an M.P. web app. It instructs the user to download and install Filezilla FTP client, configure site manager settings pointing to their individual website account, successfully connect, and then drag and drop web file contents to the remote site folder to publish the site online. Once an index.html file is in the root directory, the user can view their web pages at the given FTP address.

Emacs, a performant IDE for PerlLaurent Dami

Emacs is a highly customizable text editor that provides an IDE for Perl programming. It allows editing multiple files simultaneously, running external tools like compilers, and has various modes for Perl editing, debugging, documentation, and version control. Popular Emacs extensions for Perl include Cperl mode, Sepia, and Emacs::PDE, which provide features like auto-completion, syntax highlighting, and integration with Perl tools.

Emacs - COSCUP 2012Kan-Ru Chen

Emacs is a customizable text editor that originated from the TECO editor. It has a long history from early versions like Multics Emacs and GNU Emacs 13.0. Emacs has powerful editing commands, window operations, and help systems. It can be customized through user init files, built-in customization, and many third party extensions. Emacs Lisp allows for extensive customization and extension of Emacs through scripting.

Learn Linux: EmacsAlexandro Colorado

Emacs is a powerful command line text editor that is useful for programming and editing text files. It is highly customizable and extensible, containing many key bindings. Emacs can be used to run a shell, compose email, manage files, split windows, view a calendar, and use a calculator, in addition to editing text. Getting help on Emacs can be found through Emacs mailing lists, a guided tour on the GNU website, the Emacs wiki, and an Emacs chat room on IRC Freenode.

Linux boot processArchana Chandrasekharan

Code4vn - Linux day - linux boot processCường Nguyễn

The Linux boot process begins with the BIOS initializing hardware and loading the boot loader from the master boot record. The boot loader then loads the GRUB boot loader which displays a menu to select the operating system. GRUB loads the Linux kernel which initializes hardware and loads drivers. The kernel then executes the init program as the parent of all processes. Init runs scripts to start essential services and enters the selected runlevel, where getty processes provide login prompts and spawn user shells.

How Emacs changed my lifeyukihiro_matz

1. The document describes how the author's experience with Emacs as a student taught him about software freedom and how to read and modify source code. This led him to create his own Emacs-based tools and influenced the design of Ruby. 2. Emacs taught the author the power of Lisp and how to implement a programming language and garbage collection. Using Emacs to write code, documents and email made him a more effective programmer. 3. Emacs had a profound influence on the author and changed his life by helping him become a hacker and free software advocate.

Linux booting procedureDhaval Kaneria

The Linux booting process begins when the user turns on the computer. The BIOS loads and runs a power-on self-test before finding the bootable devices and loading the boot sector from the master boot record (MBR). The MBR then loads the boot loader, such as GRUB or LILO, which loads the Linux kernel into memory and passes control to it. The kernel initializes essential system components and starts the init process, which launches other processes according to the runlevel configuration to complete the system startup.

Elm is a functional programming language designed by Evan Czaplicki in 2012 that compiles to JavaScript. It is used to create websites and web apps as a competitor to React or Vue. Elm uses ports to communicate between Elm programs and JavaScript, and its elm/html library allows writing HTML and CSS within Elm. Elm is well-suited for building front-end applications as it provides a novel architecture for organizing code which makes managing data flow between components straightforward.

This document provides a tutorial on using XML messaging to communicate between distributed applications. It describes building a simple service that sums numbers provided in an XML request body and returns the total in the response. Code examples are provided for an XML listener that parses the request, computes the sum, and builds the response body, as well as a requestor that sends the XML request. The listener uses the DOM to extract numeric elements from the request and construct the output XML.
