GNU.Support is website promoting GNU Operating Systems and its usage in practical applications.
GNU is Not Unix!
GNU is an operating system that consists solely of free software that everybody can obtain, copy, modify, and release, even sell, provided that same rights and freedom is protected in the future for others.
There are many different versions of GNU operating system that everybody has access to and may freely download them. The full operating system and its software is licensed in such a manner that you gain four basic freedoms.
The four basic freedoms are the freedom to run the software as you wish, the freedom zero, then the freedom to study, inspect, analyze, and adapt the software as you wish, as the freedom one, then the freedom to distribute copies of software to help other people and freedom to improve or modify the program and to release such modifications as well. Everybody is benefiting.
This is kind of software that is not going to remind you that you have not purchased the license, or that your license key is expiring. Forget about that.
GNU Operating System
This website is about teaching people how to install the GNU Operating Systems and use them in practical life and business applications.
GNU is Not Unix! This is the primary postulate.
We will give incentives for people to start learning programming.
We will always use GNU Linux-libre kernel
We will follow the Free System Distribution Guidelines (GNU FSDG) even though this is not going to be a distribution at all.
By all means we will strive to support GNU Operating Systems
We will promote usage of free software in practical life and business applications, for example usage of GNU Health software in hospitals and pharmacies in East African region or usage of GNU Octave in universities.
This page is written in Org mode
Org mode is one of features of our Reach, Connect, Deliver Website Revision System, or shortly RCD WRS. It was a matter of few minutes, to add the new page type to be Org type, and instead of the standard markdown to process pages, I have added as small Lisp program as pre-processor, that is invoking Emacs to process Org files into markdown, and then the markdown to html.
I recommend reading about website revision system on the GNU website.

Azбukцeдa or azbukceda is a new mixture of cyrillic and latin alphabet as used in Bosnia and Herzegovina. It is mixture that is readable by every citizen of the country. Instead of using two alphabets the members of the society Eko Kultura speak and write in one united alphabet named azbukceda. This is new Emacs Lisp input method to write Azбukцeдa.
- Emacs Lisp: The iota function for number ranges in Emacs Lisp
This is the iota function that I had to make today. I have shamelessly borrowed the description from Guile reference manual on iota function from SRFI-1 and tried to make it compliant. I guess this could be done more elegantly. For me is important that it gives me the same result as intended.

- Emacs Lisp: why is programming language Emacs Lisp so comfortable?
My thoughts about the programming language Emacs Lisp. Apparently and initially designed to extend the GNU Emacs Editor, Emacs Lisp has grown into fully fledged programming language. Things like CGI, database interfaces, contact management, customer relationship management, project management, and so many other features becamse possible within GNU Emacs. Here is the summary on what I think what makes GNU Emacs and Emacs Lisp so comfortable programming language.
- Emacs Lisp: Record screen within GNU Emacs
The program third party program `recordmydesktop` is used for this function to invoke screen recording within GNU Emacs. You may wish to make a demonstration in video and publish such online. Record it while using few keybindings or `M-x record-screen`. This page is giving you the concept of a workflow. I consider workflow more important then the function itself. You please modify it to suit your own needs. The `screen-record-command` is spitting out the actual screen recording command, customize it as you wish.
- Emacs Lisp: Record voice notes within GNU Emacs
Sometimes you have no time to write and maybe you are talking or maybe you simply wish to record a voice note. Maybe you wish to send a voice message to somebody by email. Just use the `record-voice-note` function and it will invoke the shell command `rec` from SOX sound tools system package. Yes, you must have it or this will not work. It will record a sound note and open it in Dired. Press `q` to finish recording the sound.
- Emacs Lisp: Send Status to your GNU Social instance via XMPP or Jabber protocol
This is simple customization that helps the user to send status to GNU Social instance by using XMPP protocol. It means you could get notices over messenger from GNU Social and you could send notices over any XMPP or Jabber messenger to GNU Social instance. You are getting connected wherever you are. XMPP is much easier to use then web browser. The username `firstname.lastname@example.org` is your GNU social instance virtual friend. That is something you set up in your GNU Social profile under IM menu. Requirement is that administrator has enabled the menu and XMPP plugin for the GNU Social instance. As of now 2019-08-07 I just guess there are not so many GNU Social instances with XMPP connection. And then you need to have your own XMPP username or Jabber ID. Such need not be on GNU Social instance, it can be anywhere you wish, on any server, if you already have it, you can use your own Jabber ID to send status updates to GNU Social instance and vice versa, you can also receive messages over GNU Social instance. Change it to suit you. It is just a simplification of the `jabber-send-message` function in the Emacs Lisp package `jabber.el`. Great one! Coordinate with your team members, assign tasks directly from GNU Emacs to their messengers. Possibilities are wide to help in communication and coordination in any team. Otherwise have fun with decentralized GNU Social networks!
- Central Files: creating the countries table for the SQL database
Here we are creating the `countries` table. Contacts are related to countries. Central Files is management of personal information. Any information that belongs to any person is managed in Central Files. Everything relating to communication with any person that ever contacted the organization is managed in such collection. Central Files may be managed within the GNU Emacs editor and computer operating environment.
- Central Files: Preparing the GNU Emacs skeleton for PostgreSQL tables
To easier create PostgreSQL database tables for personal information management system by the name Central Files we will use the built-in GNU Emacs feature named Skeleton.
- Central Files: meta_tables
Central Files is management of personal information. Any information that belongs to any person is managed in Central Files. Everything relating to communication with any person that ever contacted the organization is managed in such collection. The table `meta_tables` may help us in future to indicate if such table need to be hidden or handled in special manner.
- Central Files: meta_fields table
Central Files is management of personal information. Any information that belongs to any person is managed in Central Files. Everything relating to communication with any person that ever contacted the organization is managed in such collection. The table `meta_fields` is necessary requirement for Gedafe generic database frontend. We may have use of it.
- Central Files - management of personal information
Central Files is management of personal information. Any information that belongs to any person is managed in Central Files. Everything relating to communication with any person that ever contacted the organization is managed in such collection. It could be paper base. Today, computers are used to manage such information in databases. It is my opinion that every person shall be able to design the database as they think it gives them most benefits. The pages about Central Files will hopefully help GNU Emacs users to design their own relational databases and edit information in a quick and efficient manner thus increasing productivity and communication quality and speed with related persons.
- Emacs Lisp: avoiding repetition in writing Nginx web server configurations
Imagine you are handling hundreds of domains, and each time you need to write pretty similar web server configuration for each new domain. GNU Emacs is extensible text editor and operating environment that helps you to speed up your editing. Nginx is a web server with pretty complex configuration syntax. Yet directives for each doman may be similar to each other. By adapting these functions to your own needs you may get some speed in preparation of Nginx configuration.
- Emacs Lisp: dig-txt and dig-txt-short as small extensions `dig` function
Extending the GNU Emacs built-in `dig` function is very easy with `C-h f` and function name and then inspecting how to make your extension. In this case `dig` is looking for text records which may be suitable to inspect SPF and other related DNS records.
- Emacs Lisp: duden-lookup opens up https://www.duden.de German dictionary to lookup definitions
This example demonstrates how easy it is to advise your GNU Emacs to query the word on any website. In this case it is https://www.duden.de/ German dictionary. To find a definition of a German word in German language, place your cursor on the word and run `M-x duden-lookup`. Adapt the function for your needs to open up any other website in similar fashion straight from Emacs.
- Emacs Lisp: opening media files straight from GNU Emacs Dired mode by using xdg-open
This is my personal GNU Emacs Dired setup on the V key that helps me to quickly open media files or external viewers by using xdg-open and EMMS the Emacs Multimedia System.
- Emacs Lisp: mark HTML on the web page and convert it quickly to Markdown format
Emacs Lisp: mark HTML on the web page and convert it quickly to Markdown format. This function needs your own customizations. You would mark the HTML on a web page within your browser. Then you run the Emacs Lisp function and the clipboard is converted into Markdown file. The file is opened for further editing and saved for future just as a note.
- The Guile Programming Resources
The GNU Guile is programming language and collection of programming languages, it even represents the implementation of Emacs Lisp, imagine! It is full of resources and excellent for everybody to learn this Lisp dialect.
- Emacs Lisp: take a screenshot withing GNU Emacs and `maim`
`maim` is small shell utility that takes screenshots, and with the option `-s` it allows cropping of a screenshot. This makes it handy to bind the `<print>` key to `screenshot` function. After taking screenshot, Emacs is to open the Dired buffer with list of screenshots. From there you may send them by email or do whatever you want. If you are giving it the universal argument `C-u` it will crop the rectangle on the screen.
- Emacs Lisp: switch-to-scratch and return back to previous buffer
This function is using register 100 to `switch-to-scratch` and remembers where to return back. Global key binding is Hyper key and 8 and once in the `*scratch*` buffer, the local key binding is to return back to previous buffer.
- Emacs Lisp: using mutt within GNU Emacs under ansi-term
This function requires some modifications for your own usage. As small script has to be setup to run the mutt directly with the `ansi-term` function. The script named `emacs-mutt.sh` is executed under ansi-term emulation within GNU Emacs. Editor is set to emacsclient so that all editing takes place within the GNU Emacs. Configuration files without special colors are chosen.
- Emacs Lisp: Common Lisp solution to accept Org files from standard input and emit markdown output
This was my previous Common Lisp solution, using CLISP implementation, to accept the Org files on standard input and emit markdown export from Org files. This is still working well, but the new solution by using GNU Emacs directly is more elegant.
- Emacs Lisp: emacs-org-to-html.el on command line, convert your Org files on command line to HTML output
This is one way of converting the Org files on command line to HTML output. This is script that shall be made executable with chmod +x and it runs on command line. It may be used in website revision systems to feed Org input and get the HTML output. It could redirect to HTML file quickly, without launching full GNU Emacs. You may see inside that one function is to output full HTML and other only the body of the HTML. This is for those people who need to use templates.
- Emacs Lisp: quickly insert Openstreetmap location link
This function asks the user for location, opens the Openstreetmap and inserts the link into buffer. Imagine you wish to tell your friends where you are located, so you need to give them some pointers.
- Emacs Lisp: quickly remove menu items from GNU Emacs menus
This shows how one can quickly remove some items from GNU Emacs menus
- Emacs Lisp: stockpile.el calculates volumes of stockpiles, heaps, piles, mounds
This set of function is calculating stockpile volumes depending of sizes of piles, mounds, or heaps. Engineers may be able to dissect various parts of stockpiles and then calculate their volumes by using these functions.
- Emacs Lisp: mkdatedir works in Dired and quickly creates directory by date
Sorting files is one of tedious jobs we all do on the computer. Sorting is often best done chronologically by dates. Thus function creates directory within GNU Emacs Lisp, usually within Dired listings. Sort files by groups, people, and dates.
- Emacs Lisp: produce speech by using espeak shell command
Espeak shell command is often faster then using Festival Speech. This function may be used to quickly produce some speach. Global variables such as `*espeak-amplitude*` and `*espeak-voice*` can help you set it up for your own language and volume.
- Emacs Lisp: Get ATTENTION in those emails by using heading-underlined function
Sometimes you wish to really put attention in emails to certain facts or paragraphs of text. Using the heading-underlined function you quickly get upcased heading underlined that your reader cannot miss it!
- Emacs Lisp: strip-html by Sacha Chua, remove those tags!
Sacha Chua is wonderful woman that likes GNU Emacs, notes, she has her thoughts well organized and lives a happy life. Once I had to find the strip-html function and it was just there, on her website, thank you Sacha!
- Emacs Lisp: join-lines function
When there is need to join the lines, this handy function helps me in editing those formatted and wrapped lines into one single joined line.
- Emacs Lisp: string-to-file-force function writes string to file forcefully
I often need to write strings to file, and without looking if the file exists or not, this handy function is doing exactly that.
- Emacs Lisp: file-to-list function reads file line by line into a list
This Emacs Lisp function reads file line by line and returns list of lines. This may be handy when lines of the file need to be processed.
- Emacs Lisp: read-from-buffer versus read-from-minibuffer, returns string from editing
As I am often editing database fields, and such fields could represent Org Mode or Markdown documents, this function is handy to quickly edit the string and return it back. It has no version control, thus I must take care what I am doing and how I am editing the string. As if something is lost, is lost forever. Unlike the read-from-minibuffer function, this one will open full editing buffer. If I switch the mode I have to use C-M-c option to return back.
- Emacs Lisp: use speech on your computer by using festival.el and Festival Speech system
Festival already has its GNU Emacs Support, just install festival package in your GNU/Linux distribution and you will gain soon functions to output speech. Yes, instead of messages in your Emacs minibuffer, now you can hear the real speech and in several languages. Emacs could thus remind you of new emails or new messages coming and it could tell you about finished tasks or commands. Sounds nice?
- Emacs Lisp: quick publishing of Emacs Lisp function to Internet
This is new Emacs Lisp function invented on 2019-07-15 that I am using to publish Emacs Lisp functions to Internet on my gnu.support website. It may not mean much to you as you are not using the PostgreSQL database for WRS or Website Revision System. If you do have a website, you could adapt this function to your own needs and quickly publish functions to Internet without thinking. Forget about those third party websites, just host yourself web pages.
- Emacs Lisp: how to read file into a string?
GNU Emacs is the extensible, customizable, self-documenting real-time display editor with full programming language Emacs Lisp. This function file-to-string will show you how to quickly read file.

- I have a 2 TB Hard drive (mostly used) and wish to install a Linux “distro” too along with of Windows (already installed), what do you recommend?
So should I run them both as a dual boot, maybe use virtual box, or perhaps get an SSD?
- Why should computer science students use GNU/Linux?
My teacher often advises me to use Linux. And so I installed VMware, and I have played around with Ubuntu terminal for like several days. However, I still don't know what is so special about Linux that computer science students should be familiar with it.
- Why would anyone use a UNIX other than GNU/Linux?
The major reason for the creation of GNU is the strive and intention to create free software. That means the software that respects user’s freedom to use it as they wish, for whatever purpose they wish, to copy the software as they wish, to study it, to modify it and to distribute the original software or modified software. It is about liberty, and not about the price of software.

The sitemap has been generated by using Lisp programming language, implementation CLISP, and by using the CL-EMB package. That way each page becomes a Lisp program. At the moment of generation at local computer, the sitemap is generated and HTML is created.
- Words to Avoid (or Use with Care) in Free Software Community
There are a number of words and phrases that we recommend avoiding, or avoiding in certain contexts and usages. Some are ambiguous or misleading; others presuppose a viewpoint that we disagree with, and we hope you disagree with it too.
- GNU Philosophy
- GNU CLISP is an ANSI Common Lisp Implementation
GNU Common Lisp - CLISP is an ANSI Common Lisp Implementation and general-purpose programming language and an Artificial Intelligence language, interactive, a Lisp for professional use, a standard language: the syntax and semantics will not change tomorrow at someone's whim, easy to test (interactive), easy to maintain (depending on programming style), portable across hardware/OS platforms and implementations (there is a standard for the language and the library functions), needs only 4 MB of memory, implements most of the ANSI standard, as well as many extensions, can call your preferred editor, is freely distributable.
- Programming with Free Software
Free Software with its free licenses such as GNU General Public License and others, gives programmers freedom to program and create new software. Plethora of programming languages is available such as Lisp and Common Lisp, Perl, Python, Ruby, C programming language and many others. Once you have an opportunity to learn a programming language, you should start. You don't need more than few hours to grasp the basics of programming and to create some first mathematical and textual interactions. It may be very useful to you. Each individual and each business may be assisted by few programs. And everybody can learn how to program.
- Global Markdown to Org Mode Conversion
The global Markdown to Org Mode conversion has already started. When I started using Markdown for generation of the HTML pages, I was among the pioneers who adopted it as first. There was no website revision system based on Markdown in those early times. The situation is changing today, the Org Mode, being more complex and superior to Markdown, is the future of website revision systems.
