So i'm a college student in and what bothers me is that there seem to kind of assume programming languages don't evolve or don't get replaced by better ones. Right now if you go to college you'll most likely get tought c++, industrial standards, they all have their drawbacks. And one drawback that looks important for teaching is flexibility in expressiveness. From my experience college students seem to have problems translating their often declarative thought process into actual semi compile-able code that runs in a given language. Since D seems to be a language that supports a lot of programming paradigms very well, wouldn't it be beneficial to learn people declarative programming using D for a little and from there expose them to other programming styles in thesame language to lower the barrier of entry? I think D could play a bigger role in education since its such a "clean" language that is flexible but doesn't have any real gotcha "features". Its also a language that could potentially be used over someones entire college career as the primary language. If this would be achieved there would be a higher income flow into the industry of young D programmers which will pollute other programmers with the D mind and featureset.

After all, teaching is a difficult and time consuming skill and in my personal experience consumes almost all of the time a teacher has. Leaving very little time over for a teacher to explore new technologies such as D and design new courses around them. No teacher I know knows of the existence of D. And when I tell them they assume it is not important to learning computer science. Therefore I was thinking something more along the lines of a set of free open source courses which use D to learn certain aspects programming and programming related subjects. That would most likely not draw in a lot of new programmers who start programming on their own. They tend to stick to the popular languages. Instead it would offer teachers who are looking for new new teaching material some material that is closely coupled to other material with a small set of technologies. Thus not forcing students to learn a new language every other course. I hope that that would invite teachers to use D as a language for learning.

That's why D is a hobby language.Unfortunately true. It just seems like a missed opportunity.

I don't know how much adoption there would be, but free, professional-quality teaching materials would make it much easier to adopt. One way that I could see D getting its foot in the door is an intro course using Java or Python but where the instructor wants to devote a couple of lectures to low-level programming using pointers. D would be perfect for that due to the convenient syntax. Other topics like metaprogramming or memory management would also be reasons to use D. I don't think the lack of industry usage is anywhere close to the problem posed by lack of teaching materials and instructor knowledge. After all, Scheme was widely used for decades, and in some places is still is.

I completely agree with your post however, but I don't see D ever taking off as an educational programming language in the majority of schools, because it doesn't have a job market to support it. Say if you apply for a Java job and it says you have 10 years of experience programming in D and 3 years of experience programming Java, then another applicant has 7 years of experience programming in Java, but 0 experience with programming in D.

The differences are so extreme actually, that undergrads deserve to be introduced to both. Introducing python to undegrads is an abomination! Introducing D to undergrads is problematic, since D is an unprincpled mix of pretty much everything - and more to come (which is good in some sense, and bad in another sense). D is the swiss army knife of programming langauges. What is great about D, is how it integrates it all into one tool, making it easier to use those tools. But IMO, D is not ideal for undergrads, as it's a little too unprincipled - and undergrads needs principled approaches when starting off. In addition, the syntax of C and Java is not too different, so undergrads can switch from one to other other without too much drama. Imagine switching between C and Go, or Java and Go, or Java and Python etc..etc. C and Java provide the greatest learning experience for undergrads, IMO, and at the least 'cognitive' cost.No. I do mean it. Python has no place in an undergrad course.Python should be banned! Cut of it's head!!Hopefully this is a troll, and you don't mean that.The thing is, those teaching in uni are not really 'teachers'. They are usually just filling in time, to earn some extra money or whatever, while continuing their studies or research. Very few actually know how to 'teach', and even few are motivate to 'teach'. Undergrads can learn a great deal more from just buying some good books (or even a single good book). Perhaps this is why programming should be 'taught' before students reach uni, and then they can focus on doing more productive things when they get to uni, rather than learning how to write a for loop, or move circle around the screen!As someone intimately involved with a university for many, many years, I have to wonder whether teachers are the problem, rather than the solution ;-)I can't speak with direct evidence for the last decade but certainly till then far too many academics in the UK couldn't really program well at all.

I believe D has had the biggest impact on my programming skills, not so much CS. D was great because I could try to do the Java assignment in D too, and the same for my C class. Not so much c++. As you say you can cover different levels with D.

Right now if you go to college you'll most likely get tought are industrial standards, they all have their drawbacks. And one drawback that looks important for teaching is flexibility in expressiveness. From my experience college students seem to have problems translating their often declarative thought process into actual semi compile-able code that runs in a given language. Since D seems to be a language that supports a lot of programming paradigms very well, wouldn't it be beneficial to learn people declarative programming using D for a little and from there expose them to other programming styles in thesame language to lower the barrier of entry? I think D could play a bigger role in education since its such a "clean" language that is flexible but doesn't have any real gotcha "features". Its also a language that could potentially be used over someones entire college career as the primary language. If this would be achieved there would be a higher income flow into the industry of young D programmers which will pollute other programmers with the D mind and featureset.I thought it might help if I mentioned that I successfully used D as one of three languages to teach the Programming Languages course at Vassar College last Fall. The main reason I ended up using three languages was this: 1. Most undergraduate CS courses that I sampled (at UW, for one taught by Dan Grossman, among others) use a core functional programming language such as (S)ML which really helps in solidifying some of the principles of programming languages—the concept of environment, scope, binding; functions as values; curry, filter, map, etc. Plus it has a version that comes with a REPL and really helps students explore it. That said, it is not a "industrial strength" language, and since I also wanted to empasize on the pragmatic aspects, it could not be the only one. 2. I briefly introduced the concept of logic programming using Prolog, but I couldn't really spend too much time on it and so cannot count it as another language 3. When I asked students what language they would like to choose—given the choice, most of the class leaned towards Python. That plus the likelihood of them actually using it at some point, I decided to cover some programming language aspects using it over two-three weeks. It also has some fascinating feature sets (dunder methods, some meta programming niceties, etc.) and being interpreted language, provides a nice complementary view. 4. The rest of the course used D. I used both Andrei Alexandrescu's book and Ali's book to generate the course content. I was fortunate to have a stack of slides from the Andrei himself. And even more fortunate, as it happened to spend a Boston D meetup dinner with the two and Steven Schv-guy. I have been in love with D ever since I firsr started reading Andrei's book in 2010, and it was really quite something that I could use it in an undergraduate CS curriculum seven years later. Originally, I was hoping to use D for the entire course, but then given various aspects of the course, and the styles in which it is being taught many places made me change things a bit. Oh, and I should mention that I did get a few slides from Chuck Allison who uses D to teach a small part of his course at UVU. If you haven't seen his talk at, I believe the first/second DConf at UVU, I would highly recommend it. The icing on the cake was that Andrei was able to visit Vassar in November and give a talk on his Fastware muse (if I may call it that). He was an instant success! I am scheduled to teach the course again next Spring, and I am trying to figure out how/if I can use more D than I did the last time without sacrificing some of the goodness that (S)ML brings to the table. That way I can cover more programming paradigms that D brings to life—built in unittests, contract programming, delegates, and many many more—with a flair. Any thoughts/pointers that this wonderful community can provide would be very much appreciated. -- Sameer

For some background, I work at a company that offers traineeships in software engineering to technical graduates. The traineeship is basically a crash course in high level application development. Our main language to teach is Java, because our biggest customer uses it. We try to focus on design concepts rather than programming languages. The subject I teach is object oriented programming and test-driven development. For the slides and the demo, I use D. I have two main reasons for this. Firstly, I don't want the students to become hardcoded Java programmers, who panic when they need to switch languages. I want them to gain the confidence that the gap between various programming languages (mainly in the C family, or one family in general) is very small and, more importantly, that they can transfer the knowledge they already have. Secondly, I want them to focus on the concepts. During a demo, if I ask them how to set up a test in Java, they think and answer in code. If I ask them to set up a test in D, they think in concepts. I then do the translation to code. (For the record, they implement the assignment in Java.) Last course, we had a normal group of Java programmers and a trainee who was learning Python. The trainee was the one who understood the OO principles the fastest, because she was forced to think in concepts and not implementation. For my personal studies, I programmed in Ocaml for a while. Even though you can mimic the concepts in D using pure and const, it still broadened my horizon. If I have to conclude anything, it is that there, in my opinion and in the context of my philosophy, should not be a one language during a study. D definitely has a place in there with how different language features are set up. I think Ali's book is a great start, as it explains the concepts as well as the implementation. The D lang tour for example focuses on learning D when you know how to program, which is a completely valid use case as well. It would be cool to have a "Learn programming with D as a tool" section on the website, but I doubt it would be worth the effort. People who study in their free time go to well-known sites like Code Academy and people who have their own course (like me), write their own material based on their course setup and learning goals.

For no other reason than to provide a fun data point: I am having two graduate students to learn D for use in my computational biology lab 😀 Most bioinformatics work is and remains in Python; for higher performance we have previously used go, but the students indicate D is worlds more pleasant than either C++ or go.

D definitely has a place in there with how different language features are set up.and broadened my scope of languages and programming styles from then on. Besides learning the languages, I the most important thing we were tought was to be language agnostic. While I can't say I completely am, I can carry over ideas from one language to another. I think that D is a useful language in this regard because it has a realistic, pragmatic and theoretically "correct" way of constructs you find in other languages while not limiting the user. I think that this is very important to teaching. In contrast, when there were lectures about databases the main database the course focussed on was MySQL. Which is not neccesarily a bad choice as a teaching method. It's just that MySQL deviates from the standard more than for instance PostgreSQL. Therefore it was relatively difficult to learn databases and SQL and at the same time make the assignments for MySQL since there was a small translation step in the middle which had to be taken. Taking this step away could give a boost to learning and maybe a better understanding.

D would be perfect for that due to the convenient syntax. Other topics like metaprogramming or memory management would also be reasons to use D.Hmm sounds interesting. Maybe writing runtimes for relative simple languages in D as a course? On Sunday, 6 May 2018 at 01:35:53 UTC, Seb wrote:everyone in this discussion: you ask and answer the wrong question.
