Some programs need to use the command line. There is an article about [https://www.lifewire.com/how-to-open-command-prompt-2618089 how to do it on Windows]. If you use Linux, you may use [https://sites.google.com/site/pleyadestest/david/projects/sakura Sakura], for its light-weight and Unicode support; If you want to customise the font in command line on Windows, you can use [https://conemu.github.io/ ConEmu].

The customisation of some programs require a text editor. It is recommended to use [https://www.geany.org/ Geany], because it is lightweight and has useful shortcuts like “Ctrl + D” to duplicate a line.
Some programs split words in a sentence with spaces. In this case, texts in Chinese, Japanese, Thai, Vietnamese and other languages need a [https://polyglotclub.com/wiki/Language/Multiple-languages/Culture/Introduction-to-some-language-tools#Word_segmentation word segmentation].


If you see GitHub or GitLab links, please notice that the download icons mean to download the source code. Unless its language doesn't require compilation, you would need to build the program on your own with the source code. Links to download binaries (built programs) are elsewhere like “Releases” or links in the README.MD file. If you see there are multiple links in “Releases”, select the link with your corresponding operating system, CPU architecture and other clues in its filename. The “amd64” and “x86_64” have minor differences and are usually considered the same when describing a binary. “md5”, “sha256”, “sha512”, etc. are checksum formats, which can be used to check the integrity of the downloaded file. You can use the open-source tool [https://gtkhash.org/ GtkHash] to check the integrity of the files with the same name of the checksum files.
To customise the display of webpages, see [https://greasyfork.org/ Greasy Fork] to find corresponding tools.

To run a program written in JavaScript, there is [https://fireship.io/courses/javascript/beginner-js-where-to-run/ a guide].
If you don't see an executable file in the program, then you may have to compile it and then run it, if the programming language of the program requires it. You may find details on the internet.
 
JavaScript and some other languages support running something with two programs: a server and a client. You need to start the server, then access the server with the client.


JavaScript programs often utilise Electron.js to have cross-platform support easily, which integrates a Chromium in every program and occupies a lot of resources. What's more, it has been depending on Node.js, which has been having the background of political activism (Black Lives Matter). Political activism can cause unexpected damage, like [https://securityaffairs.co/129174/hacking/node-ipc-npm-package-sabotage.html node-ipc by RIAEvangelist on GitHub]. Also, GitHub has the background of political activism (pro-Ukraine).

See if the program is updated recently. Outdated programs may be no longer reliable, because they may rely on something else, like another program or a webpage, which can become invalid with the change of time. It may also contain security loopholes that were not discovered at that time and discovered now.
 
Some jerks cram all codes into a single line so other people can't easily study the code and modify it, while putting the program under an open public license. In this case, the deobfuscation is required. However, the need of deobfuscation in an open-source program disqualifies it as a valid choice.

So, let's dive into the world of polyglots and explore the best internet resources to help you become a true language enthusiast!

-- Introduction --[edit | edit source]

Advices[edit | edit source]

This page is updated from time to time, not frequently, not regularly. “But how do I know what you have changed since the last time I come here?” Try this: hover your mouse over “Actions” in the upper right corner of this page, click on “history”, select the current and the version you saw last time, click on “Compare selected versions”.

It would be great if you pay a visit to every site on the list. Don't lose your curiosity.

If you want to do creative work to help others to learn languages and to know about cultures, please visit Language/Multiple-languages/Culture/Productivity-tools-for-polyglots.

It is not recommended to put some banner like “featured in Polyglot Club” on your website, because this list is dynamic.

It is highly recommended to have privacy protections on. There are resources on privacy:

Tips[edit | edit source]

Some programs require the use of command-line. There is an article about how to do it on Windows. If you want to customise the font in command-line on Windows, you can use ConEmu.

Some programs split words in a sentence with spaces. In this case, texts in Chinese, Japanese, Thai, Vietnamese and other languages need a word segmentation.

To customise the display of webpages, see Greasy Fork to find corresponding tools.

See if you are downloading the binary file or the source code. Unless its language doesn't require compilation, you would need to build the program on your own with the source code. Links to download binaries (built programs) are elsewhere like “Releases” or links in the README.MD file. If you see there are multiple links in “Releases”, select the link with your corresponding operating system, CPU architecture and other clues in its filename. The “amd64” and “x86_64” have minor differences and are usually considered the same when describing a binary. “md5”, “sha256”, “sha512”, etc. are checksum formats, which can be used to check the integrity of the downloaded file. You can use the open-source tool GtkHash to check the integrity of the files with the same name of the checksum files.

If you see SourceForge, you may simply click on the “Download” button. In some cases, the downloaded file is not what you want. Then you need to find it out in “Files”.

If you don't see an executable file in the program, then you may have to compile it and then run it, if the programming language of the program requires it. You may find details on the internet.

JavaScript and some other languages support running something with two programs: a server and a client. You need to start the server, then access the server with the client.

JavaScript programs often utilise Electron.js to have cross-platform support easily, which integrates a Chromium in every program and occupies a lot of resources.

Java relies on a virtual machine, which is an emulator of a computer system and requires some more system resources.

See if the program is updated recently. Outdated programs may be no longer reliable, because they may rely on something else, like another program or a webpage, which can become invalid with the change of time. It may also contain security loopholes that were not discovered at that time and discovered now.

Political activism can motivate people to cause unexpected damage, like node-ipc by RIAEvangelist on GitHub.

Resource Selection Criteria[edit | edit source]

To be listed on this page, resources should possess at least one of the following characteristics:

  1. be rich in FREE content (not just a trial or not fulfilling the need in the free part), and the free content is mostly accurate, and the free content is not all covered by other free ones;
  2. be made with a unique, good idea;
  3. has no better alternatives.

Resources possessing the following characteristics will be given disadvantage:

  1. propagate specific political or religious ideas without possibility of discussion.

Resources with the following features will be given a little priority:

  1. available offline;
  2. available on multiple platforms;
  3. multilingual user interface;
  4. lightweight (including “written in C”);
  5. open source;
  6. privacy-friendly (including “registration not required”).

This one supports a lot of languages in Latin script, but it means to learn typing again. It is worth it. You may have noticed that “Kolemak” is even better than Colemak. How to modify keyboards will be discussed below.

A better layout image.

Note that the download link on the home page is “Caps Lock Unchanged”. The idea of replacing Caps Lock with Backspace is great because of its convenience to press Backspace, but having it unchanged is generally better because it's punitive to press Backspace, urging you to make fewer misspellings.

There is a flaw of no “„” or “‚”. You can replace “÷” and “×” with them. Also, the positions of single and double quotation marks only benefit British people for not pressing Shift. You can exchange their positions, too.

There is a modified version and local variants.

Based on French, giving consideration to European languages. But if you don't type French much, it might be not ideal.

No English translation for this site, but it doesn't matter, because this keyboard is generally pre-installed in common operating systems. You just need to find it in the “French” section of keyboard settings.

https://forum.colemak.com/topic/519-rulemak-russian-colemak-layout/

Variant of Colemak for typing Cyrillic. It is available as source code. It is pre-installed on Linux, but it requires some effort as mentioned in the “Colemak” section to make sure it appears in the files. “Greek (Colemak)” is also available.

For Windows, Portable Keyboard Layout is required. Or you can use that keyboard creator to do it manually.
