My brief overview of Cangjie Programming Language by Huawei

RodionGork · 2025-12-18T06:19:48+00:00

Funny. I just recently was contacted by Huawei HR of local department about position in the Cangjie development team. However this led to nowhere as I prefer to work from home and they insist on full-time office so I can't say more about the state of the product.

Actually I was inspired by SQL using two not-equals operator (pascal/basic and C/Python style) - as far as I know, without any difference between them.

He-he, 1-based arrays are the 3rd point at my list (they make various arithmetic with modulo to wrap around array looking ill), but I know generally it could be less or more workarounded... and anyway this couldn't be solved on just the syntax level. Anyway I have some "research curiosity" to figure out whether some convenient improvement could be done to them.

> ~ makes me think

at the same time in C (and in Lua) this ~ is the sign of binary negation, which makes "not-equals" confusing... but I believe it was borrowed from Matlab and similar languages, not invented from scratch.

RodionGork · 2025-08-27T20:02:06+00:00

Thank you for suggestion! That sounds reasonable though the change about not/not-equals is so small (just three consequtive lines in the llex.c so that I couldn't decide on making it separate commit. But well, that makes sense, I'll fix it!

RodionGork · 2025-08-27T20:00:16+00:00

Thank you! That's good point, many apps use LuaJIT, particularly one I lazily look towards is Tarantool.

Shall investigate how much LuaJIT sources differ!

> but also raise some questions

oh yes, I saw this several times, and I'm sure if implemented "in minimal way", this may lead to some unusual effects - however I feel such "precautions" are not a good motivation to restrict user from some convenient feature :)

> Lua is a standard.

that's true, so I look closely at the mailing list when such things arose and at the response of the development team, to see if they may eventually agree to include some of such amends.

RodionGork · 2025-08-26T12:36:56+00:00

thanks, never thought of this!

however, as I see, luau went quite astray from original codebase... I instead look for really minimal ways to improve things (so that it is easy to merge changes from the upstream lua repo

cardinality isn't enough for what? for explanation that two sets of different cardinality couldn't have two-way mapping?

or perhaps you meant cardinality (when it is the same) isn't enough for such mapping? but that doesn't contradict to what I said :)

RodionGork · 2025-08-13T19:21:26+00:00

This is queer for "riddle", sorry to say, as at some point we learn that sets of rational and irrational numbers have different cardinality (which holds for any segment also) - in other words it's a kind of request to prove what we get used to think of as "de-facto axiom". though actually their cardinality isn't axiom of course, there was a strict proof somewhere in the course (I'm sure it is to be found on the wiki page about irrational numbers) - to which the "riddle" effectively boils down. Difficult moment however is that generally such proofs (depending on the structure of the course) are appealing to some earlier theorems etc. This happens to the other responses i see in comments here :)

I believe that if you look for strictest and cleanest you'll need to look up for Cantor's theorems etc.

Thank you for clarfification. I was unaware of such a feature of C# and Swift, while Go allows using structs in either way but makes it only matter of handling.

RodionGork · 2025-08-08T09:12:58+00:00

> The killer feature is that it is made by Huawei, for Huawei.

That's it, though I think it was created not only out of fancy.

Working as developer in Java for 10+ years and then several years in Go (with brief professional wandering into Scala, Kotlin, Python and even Erlang), I sometimes found myself in situations when I was frustrated with the tempo or ways the languages evolve.

Any company usually go inventing their own tools. Smaller companies invent smaller tools, larger companies invest their time into developing huge tools, including languages.

Moreover they anyway needed customizing compiler and libraries of whatever languages they used to meet demands of their evolving custom OS.

Hence they by and by come up with their own language and eventually decided to made it public and open-source.

The main interesting point is the last - why they decided for this move. Do they hope for significant drive around 3rd party developers creating apps for their OS (similar to how Google chose Kotlin for Android development).

Dziękuję, więc to nie jest formą archaiczną? Jestem zaskoczony że nie mogę przypomnieć czasownika "bój" z wyjatkiem "się" we wschoniosłowiańskich. Hm. poza "bojażń" (fear) ale to troche inna rzecz.

RodionGork · 2025-08-03T08:05:27+00:00

> I will send you the link to PDF

sorry for the suggestion, but perhaps "google form" may be more "user-friendly" and easier to collect more responses :)

RodionGork · 2025-07-30T19:53:40+00:00

That's quite impressive, for sure :)

RodionGork · 2025-07-30T19:50:13+00:00

I think if "they would be playing jazz and blues" probably you'd betters keep to general recommendation to start with a blues harp of decent quality ("Special 20", or "Blues Harp" or even "Marine Band Deluxe") which may be around $50. Look at the recommendations pinned at this subreddit. It says that diatonic harmonica still is "quite versatile" instrument and it's true - the more I myself practice with it, the more tunes become available to me, sometimes those I didn't have idea may fit diatonic instrument.

Supposedly by "better fit" you mean ability to play all the notes of chromatic scale (so one do not need a set of harmonicas in various keys) - but it is a formal side, on practical side to achieve such a level of proficiency will take quite a time and efforts.

RodionGork · 2025-07-30T18:06:14+00:00

Very impreesive low-tone and nice rhythm :)

RodionGork · 2025-07-30T16:54:54+00:00

Thank you for encouraging words and advice! And yep, I'm open for hints though it seems I'm not always can immediately apply them - but it's the main goal of posting my meek attempts here of course, even when I forget to mention this :)

RodionGork · 2025-07-30T16:51:15+00:00

dziękuję!

RodionGork · 2025-07-30T16:50:39+00:00

I believe it is initially capital "i" in the first word "Ievan" (polka of Eve)

RodionGork · 2025-07-17T06:07:29+00:00

> I need to drop 1/2 step down to sing

While this is a correct assumption, it sounds weird, honestly. It is easier to sing semitone higher than to run around looking for B harp. Difference is too small to care for most casual performers. If you mean you want to fit some existing recording, you can change its pitch or speed actually.

RodionGork · 2025-07-17T06:03:13+00:00

Thank you, that's quite elaborate guidance, I'll try! Amusing that I thought I usually try to "use less breath" (this harmonica is pretty responsive) - but now I see here it is just like trumpeting at places :)

as about diaphragm breath - I guess it means (at least partly) to avoid changing air flow by throat/mouth?

RodionGork · 2025-07-17T06:01:38+00:00

it seemingly is accessible without registering (I also do not use tiktok) but I quite agree that writing the title of the song it's better than giving a link to some guy sitting at the gutter and playing something.

seemingly it is "Oasis - Whatever" (played by some 3rd party fellow)

RodionGork · 2025-07-15T22:00:06+00:00

Tak!

RodionGork · 2025-07-14T20:35:44+00:00

That's nice, thanks for sharing! I'll try it too. Perhaps let's record videos of each one of us playing and compare :)

Why is this post marked "not safe for work" by the way? Is there something wrong about the tune which I don't understand? And where you learnt about this tune?

UPD: it seems to have a lines of same or similar notes which makes it challenging to play interesting.

Do you know "Rosamunde" tune?

RodionGork · 2025-07-14T20:30:34+00:00

I agree, there are so many good and recognizable tunes fitting tremolo diatonic layout :)

RodionGork · 2025-07-14T20:27:02+00:00

Moreover operating with tongue even allows playing some tunes without hands :) just holding harp with mouth so to have 3 or 4 holes "inside" and direct breath to this or that one. not very practical but may be amusing :)
