Hi Dan,

Thanks for taking the time to reply.

My comments below.

I prefer a simple language with simple features :). You claim: "the number of bugs can significantly go down", do you have a serious study to prove that?

I do not have any proof. But I say that from my experience with PHP and Scala. For example, PHP does not have a O(1) hashmap. There are several other examples that I can give.
The fact is, a simple language does not give you all the tools that you need. You can develop any way you want it to. This is the problem now with JS ecosystem. There is lack of standard frameworks and tooling. Sometimes it is better to be opinionated.

I see that you link to a StackOverflow question, but I don't see any study mentioned on the answers. Where is the prove?

Since we are dealing with opinions and not lemmas, I dont think we can prove either of them. But what we can do is gather collective opinions. I believe stack overflow is a very mature community to discuss such issues.

Productivity claims are yet another can of worms, from which I have never seen a proper study to prove anything

I use a strategy called proof by contradiction. Dynamically typed languages claim to be better at programmer productivity but from my experience of coding, they never work out for large teams. Hence I do not see what they are good for. You can neither prove this nor disprove this.

Completely agree. Better not to give those idiots a gun to shoot themselves on the foot.

What I meant by this is no matter how much a good language you have, there is always the need for code reviews. Nothing beats that.

Do you think the argument will end if we had enough data? Would we be ever be able to have the data?

I dont think that is the question we need to be asking. We have had several years of discussion around this and there is nothing conclusive. So I would choose whatever language that works out well for the team. This is of course based on several factors such as community/library maturity, ease of learning etc.,

One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies.

I would go with the latter any day. When coming to languages/frameworks, people tend to be overly creative. Instead of creating their own, people can always contribute back to open source/existing stuff and there is a very strong relation between the maturity of the language and the library maturity. An example would be the JVM ecosystem vs ruby ones.

Hi Madusudanan,

I see that when we talk about simplicity, we are not using it in the same way. In the article I mean "simple" as per Rich Hickey definition, which he explains in this one hour presentation.

Funny that you need one hour to explain what simple means :).

About large projects, I haven't personally work in any large codebase for the last ten years of my career as I have been doing SOA/Microservices.

What do you think about microservices? Isn't it a way of avoiding big complex codebases?

We are leaning towards the same definition of simple. But where we differ is how it is implemented in languages. You should take a look at martin odersky's talk working hard to keep it simple. A language being complex to learn is not necessarily the same as its usage in applications. There are some languages that get this right, such as scala.

What do you think about microservices? Isn't it a way of avoiding big complex codebases?

I don't think microservices is the only answer. Services can be split if they naturally have a boundary. In my experience if the application talks to the same database schema then it would be unnecessary overhead to create everything as a micro service i.e instead of database calls we would now be using REST APIs. HTTP while being a good protocol is definitely not a replacement for regular method calls within a language. I tell this because most of the microservices discussion end in a way that split everything as small as possible, which is definitely not the goal of microservices.

But it can definitely help to a great extend if done right.

Of course my experience is limited and I am not an expert in any way. Just my 2 cents.
