You are Chinese? What You think about this? https://klawiatura.wordpress.com 

Thank you for the comment. There are lots of "customized keyboards", you can define the layouts (all the logical definition of the keys and some physical combinations are supported but not like the link above).  GH60 for example:

I'm Chinese. Even though there are thousands of frequently used Chinese characters, we need only the 26 English characters (plus numbers and a few punctuation marks), so the standard layout is good enough. We don't use keyboard like this. ;)

Japanese need more keys (look at japanese keyboard, is different than latin)

French have more chars , programmers need chars AND [];'./?> etc.

this keyboard are very nice but I'can see degree ° or ø or  § (appear in apple keyboard) and potenciometer for volume control

many language needed altgr (right alt) near space for language char

ą=a+ogonek ł=l+slash ż=z+dot above etc

That's a really nice idea! I guess that it could also be implemented as something that can go between an ordinary keyboard and a computer. Your project is more fun, though :-)

Thank you for the comment! The first comment I received here. Forth is an amazing language, however, few people nowadays know it. Probably its light-weight and flexibility caused this result, as it might be hard for large project and collaboration. No matter what, Forther can still benefit from it. Hope that Forth could be BACK :)

Forth is amazing, "it's bigger on the inside". 

It's also an old cultural thing, related to ALGOL vs. LISP (A: powerful but finite vs. L: simple but unlimited). I take it for a fact that changing cultures is the hardest thing in humanity. Of course, it's possible to do large projects with Forth but the A culture is dominant, and has generated many many subcultures (e.g. Pascal, BASIC, C, C++, Java, C#, Python ...). There are some L cultures, that live "inside" the A societies (e.g. Smalltalk, JavaScript. Clojure).

This said, your examples for the usefulness of a reflective, concatenative language inside a keyboard reaches a lot of A people. They look at it like at an exotic fruit in the supermarket they see for the first time in their life, and it's almost like they understand for a fracture of a second that the world is bigger than the mega-city they're living in. Some might be tempted to buy a plane ticket. Some, and merely tempted, not really doing it. Of course, you can try and offer them a blue pill (or a taste of the blue exotic fruit ;-).

All those who get into it say so. Doctor Who is one of my favorite TV program.

For me, Forth is the best language for bootstrap of a CPU with brand new instruction set (the best alien language?), however, it's not quite friendly to human (as the A languages you mentioned). In China, we learn a little classical Chinese, that used not nowadays but in ancient times. I can hardly understand  an article in classical Chinese even though I know each character in it, as the characters' meaning and usage changed over time.  Due to the resource limitation, the meaning/behavior of a Forth word might be different in different implementations (especially for embedded systems) , and I have to read each word if I want to understand a Forth implementation, even though the number is not very large.

I don't know many computer languages. C is my "native" language and Forth is my first foreign language (except C-like languages). Sometimes I feel that C dominates my brain, in other words, I often think about a problem in C. So I'm not sure if the BACK is pure/true Forth, and I even don't know what is a pure/true Forth, or it's just a philosophy not a language? For example, are the different implementations just some different libraries in Forth (like C libraries, written in C, but if you want to know how to use them, you must learn something beyond C), or different dialects of Forth (In China, there are lots of dialects, and people may not understand each other in different dialects. Someone told me the difference between some Chinese dialects might be larger than English & French)? People may not understand each other even though they both speak "Forth". I know there are some standards, but I'm afraid lots of Forth implementations don't comply with them. Maybe we can implement an abstraction layer, and all Forth programs can run on it (perhaps it's the standard itself). However, sometimes we can't due to the resource limitation. Maybe I'm too greedy. 

Few (and few) people in China know/use Forth, so it's hard for me to discuss with a Forther (as my English is not very good). Chinese dominates my brain like C, so it's hard for me to made myself clear in English (or maybe just Chinglish).

> For me, Forth is the best language for bootstrap of a CPU with brand new instruction set (the best alien language?)

That's especially true for an STC Forth (if the instruction set allows it)

That depends on the human. I've learned to know one person who has trouble with A languages (Like yoda we speak.  Hmmmmmm.)

There are standards one can use, and modern µC-Forth systems do a pretty job at it (e.g. NoForth, AmForth, Mecrisp...). Forth systems the predate ANS-Forth are different, and many dialects exist. Sometimes a platform is too limited for some of the ANS concepts

> , and I have to read each word if I want to understand a Forth implementation, even though the number is not very large.

That's also a problem of L languages, I guess.

I had a discussion about whether it's possible to learn Forth by writing a Forth. It's a bit the same as learning languages from radio news only. One has to "live" in a language to understand all aspects/

> and I even don't know what is a pure/true Forth, or it's just a philosophy not a language?

Some would say that the philosophy is more important than the language. The ANS-Forth people think the language is more important (because L should be more like A).

> Someone told me the difference between some Chinese dialects might be larger than English & French)?

> People may not understand each other even though they both speak "Forth".

That's also a problem of L languages, I guess: how can you communicate in a language that no one else speaks?  "Unlimited" is both an asset and a curse.

That doesn't always work: if the basics are different then the whole structure will also be different. Some things in standard Forth also assume that the dictionary is in RAM memory, which is often not possible in embedded systems

Nah, your English is perfect for communication, and there are many ESL speakers in the world. Congrats for mastering a foreign language this good!
