dotGo 2015 - Rob Pike - Simplicity is Complicated

Go is often described as a simple language. It is not, it just seems that way. Rob explains how Go's simplicity hides a great deal of complexity, and that both the simplicity and complexity are part of the design.

The company I work for, had one of its most important components for its server architecture written in Go. It went virtually untouched for 4 years when the individual who wrote it quit. I picked up the mantle with no prior experience in Go.. upgrading to the most recent version of Go had 0 breaking changes or gotchas. Now i understand why, from watching this video on the philosophy of Go.

[@fennecbesixdouze1794]

I think it's funny that Pike's famously complained about Niklaus Wirth's strict separation of behavior and data, and then he ended up creating a language where you have interfaces that can only contain methods and structs that can only contain data. I think it ends up being a beautiful synthesis of both the ideas, especially the wonderful idea of implicitly satisfied interfaces.

[@ezequielvalenzuela3627]

...but the data (structs) can include function (type) members/fields, which you can assign to and therefore have a way to specify/override behaviour

javascript has been re-solving all the "solved problems" since the 1970's, and still getting them wrong. it's an embarrassment of language design. if that's the bar to compare to then go-lang, I guess, is a success. But that's a remarkably low bar.

[@gareginasatryan6761]

Benjamin Scherrey i think it fundamentally has to do with the web dev culture. They’re very prone to pragmatic solutions that are very shortsighted and don’t really have a deep computer science pedigree. It’s not an accident that both PHP and JS are smashing successes in the web world and are (or for many years were) incredibly poorly designed. Most web devs are more interested in the next killer app than stack vs heap.

[@Hexanitrobenzene]

[@Whatthetrash]

This is a cool talk. Of the many things it does, it clearly demonstrates that what some people call "simple" and what others call "simple" are very different. He keeps saying this code is simple, but I find the syntax of Python FAR simpler. Like, Python just says what the thing is -- which is why I think it makes so much sense to so many people who don't identify as programmers or don't wish to be systems programmers. There's this translation step, (a degree of separation), that virtually all programming languages use -- Go included -- that's a big part of why I've never been able to fall in love with other languages besides Python. Take print, for example. Print in Python is simply: print("whatever you want"). That's it. The action and name of the action are one and the same. Print in Go is three different functions: fmt.Print(), fmt.Println() and fmt.Printf(). This from a language that supposed to be *simpler*? Before you can print anything you have to pick which print function you want and decide how it will be formatted. To my brain, this is FAR more complicated that just...print() -- and that's it. And every time you see that print function in Go (whichever one you decide to choose), you say to yourself, "Oh, this prints something here...", but you *see* is fmt.Println() (or whichever one you chose). This is the translation step I was talking about. You see one thing and then have to interpret/translate that thing into what it *means*. Python is the only language I've found that this "translation step" is virtually nonexistent: It just tells you what the thing is (and I love it!). print("apple") means "print apple". (On a side note, I particularly hate the "system.out.println()" of Java. Sheesh. Just...wow, that's awful.) Of course, this readability and "lack of a translation step" continues to all aspects of the language in Python, not just the print function (lol). It's part of what makes it so astoundingly clear (and fun!) to both read and write. Anyway, just my take. Different strokes for different folks. I'm looking into learning Go, saw this and then all of the following came to mind. Just sharing. Much love and cheers! :)

[@brandongregori995]

You are confusing the language with the standard library. It doesn't matter if there are 10 print functions in the standard library. In fact, the more functions you have to do things a desired way, the simpler the developer experience is. Also, this print argument is incredibly weak anyway. print is never hard for a beginner in any decent modern language. It's literally the first thing anyone learns. Try comparing multithreading or writing performant code. Need performant code in your Python application? Okay, better write it in C then.

[@nanderv]

With python the translation step is a bit later in the process. When your application becomes hellishly slow, and/or you try to introduce concurrency then you get such issues. Compare python's multiple inheritance of classes to golang's structs and interfaces. class Dog(Pet, Animal): def __init__(self, name): super(Pet).__init__(name) .... vs type Pet struct{ Pet Animal } Python is the king of 'looking simple', but being incredibly difficult to get right. Writing a webserver in python is very little effort, but getting it production ready (= multithreaded in 2024) is a hellscape. Go has channels which work well, python hides it all in libraries, etc. It has the global interpreter lock, another weird concept which you have to get your head around. With python, the magic is there, until it's gone, and then you're suddenly in a hellscape. Go gives you a simple world full of simple concepts. It's harder to get into the world, because there's much less magic going on. However, in exchange it doesn't rugpull and put you in a situation where your production application is bizarrely slow and you have no idea why. Also, I hate runtime errors, and any language that doesn't defend me against them to the best of it's ability is just shit.

Many come to Go worn out by the complexity of other popular languages and then after a moment having forgotten why they left the previous languages behind they start asking why Go can't be more like the languages that wore them out. Go isn't the only language nowadays for which any proposed changes must go through a rigorous process of peer review but it having started it earlier in its history than most there's less of poorly thought through features added that don't fit in with the rest. The slow rate of progress might feel frustrating to many but if that's a problem they can always turn to Rust or a minimalist subset of C++.

Love this talk! An ideal language is something that has simple primitives to get started with clear and comprehensive standard libraries. Lots of other languages failed to do so as they expose too many “features” to users of the language (hard for these languages because of legacy or some other reasons). The balance between capability (expressiveness as mentioned) and simplicity is hard to find but at the end of the day language creation is not for the language but for the people using it.

What is "orthogonal features"? Any examples?

[@mik13ST]

The Vivaldi web browser allows users to tile selected tabs (vertical split screen). That is not orthogonal, because the ability to see two things in a split screen mode was always handled by a window manager of your desktop environment. There are two users. User A wants a feature X and user B wants a feature Y. You are a maintainer of that project and you decide to not implement these features directly. Instead, you allow users to implement these things themselves (through plugins usually). You only define an interface for the plugin and that's it. That is orthogonal. There are two ways to download a file in Linux terminal. The tool A (wget) retrieves the server response and saves it into a file. The tool B (curl) retrieves the server response and echoes it to the terminal (STDOUT). The Linux terminal typically allows redirecting the command output to a file and that makes using tool A (wget) not orthogonal. The tool A (wget) doesn't have to implement saving to a file when the terminal can do that for any command output.

[@mbharathititit]

Well 7 years later, Go now added support for generics and planning to add standard error handling, which "sort of" inspired from other languages. The very thing Rob frowned upon here talking about other languages maturing. Go is great but I guess too much emphasis on "simplicity" is also making it limited. While it has great Concurrency model and simple coding style it's limiting with features such as "implicit interfaces", lack of strict immutability, somewhat confusing pointers usage etc;. This limits dev flexibility while forcing engineers to find alternate ways of writing code. I like Go. I love C#. One's not better over the other. If anything, C# 10 & 11 versions show how the language has matured to be "simpler" to use.

[@bawzzzz]

Generics is a bad fit for go, don’t think everyone is overjoyed that they are adding this implementation to the language, far far from it. Rob Pike had a great vision that brought the language to great heights, now let’s watch the downfall as they are forcing in every feature of every language into it. It’s going to be brutal.

[@thebatchicle3429]

Go is not planning to add new ways to handle errors. All the discussion around that is centered around Go2, which we are nowhere near. Also strict immutability, etc. really don’t actually add anything to the language, nor are the pointer semantics confusing in the slightest

[@robinmartens4662]

6:18: "Features hurt readability" Based on my experience, I disagree. E.g. the with-statement in Python - which was added in 2005 - more than 10 years after the inception of the language - greatly improves readability. It tells not only the interpreter, but also the human reader, "I have a resource here that will be released after use", and the life-time of that resource is the indented block beneath "with". I can make a similar case for templates in C++. By contrast, Golang's notorious if err != nil { return err } clutters source files, the way exceptions don't. Sure, exceptions have their own issues, but with-statements, finally clauses and C++'s RAII idiom nicely pair with exceptions getting rid of repetitive checking for error codes. No, I'm not arguing that Python or C++ were better than Go, or that there were no useless features in many languages that make code unnecessarily complicated, but I am firmly of the opinion that the statement "features hurt readability" is not generally applicable.

[@schok51]

I agree. Some features(abstractions) can improve readability. I also agree with Rob's point about feature orthogonality, though. You can solve a problem by adding a new feature to address that specific problem, or by choosing your initial set of features such that they can be combined to solve any problem. The with statement is something I love in Python, but consider how a language like Haskell does it: wiki.haskell.org/Bracket_pattern. Basically, functions are all that you need. The only thing the with statement actually added that was missing, is the block syntax to delimit the code block that runs between the enter and exit. In Haskell, that role is given to lambdas: with (open "/tmp/test") close \file -> putStrLn (read file) So instead of adding a new feature to solve the specific problem of "context managers", you use existing features, like multiline anonymous functions, which is already used to implement other features. For example, here's how one might "implement" a "for each" loop like Python's without needing special syntax: forM (range 10) \i -> print i In both those examples, the're are about 4 fundamental features in there: * named functions * anonymous multiline functions * datatypes(e.g. whatever the range function returns is a concrete data type, like a list) * typeclasses(i.e. interface/protocol, here for the iteration and the side effect) I'm not saying Haskell is a simpler language, or that functional programming is a better solution. But by choosing the feature set wisely, you can avoid having to add new features to address specific problems and instead rely on existing features to address multiple problems.

hmmm, but does a simpler featureless programming language really make code more readable? In some ways I guess, but I feel like the quality of the person programming is always the main factor.

orthogonal and basis vectors :) I guess that is a good analogy to redundant features.

[@thorsteinssonh]

Go may not make the problem of rouge developers worse -- only I'm disinclined to believe (gut feeling) it makes it measurably better. Does limiting syntax, limiting tools or limited coding style make a bad programmer even fractionally better a developer or team-player? That person in my experience often writes in a language called "spagetty" - and Go has no anti-spagetty AI built into it yet. I just suspect that the flexibility to wreak havoc offered by any "general purpose" language is going to be overbearing - and small systematic restrictions within the language tenuous. Off course, that being said, Go has features that do really help us a lot.

[@AJewFR0]

Hello from the future, How i see it is that in a lot of settings where go would be used, the barrier to maintainability is the complexity of the language grows with time. The amount of knowledge required to understand what is going on increases. The whole point is that if you constrain knowledge requirements to understand previous code (not just the language, but the complexity of the ecosystem that you can assume will be used) you make more maintainable code. Think how in java you have to relearn how to solve the same problem depending on what java version it was written in. or how python2 to python3 was.

Funny, now I learnt rust, feel generics is not the worst problem of golang, the interface escape is the biggest problem, more interface you use, more it will be like java minus the rich type system java offers, if using interface causes objects to escape to heap, it is not necessarily fast. Another thought on generics, it is ok to write verbose code, but it is painful to provide a library without tons of empty interface, empty interface is really bad to use and really bad to perform.

Great talk. Though I must say that Go contradicts itself on some points. Like being concise and short but I have to write a for-loop for everything collection related! It doesnt have to be a functional language but please give me filter and a map function on slices. Sure, everyone coming from school knows a for-loop, but when reading the code I always have to understand the whole loop just to know what it is doing (or extract every looping into its own function which also clutters the code)...in most cases it is some kind of "filter that element" and "do something with that element". Maybe a loop is faster, but usually it doesnt matter and in case I need it to be a couple of cycles faster I can fall back to the loop. Also all this c-style abbrevations...iota anyone. Last but not least the server example given at the end. This has nothing to do with the language. It is just an API. I could write a one line server call in any higher language. So I am going to learn more about Go, especially as a replacement for Bash, but I think I will not love it

How a system programming language can be use to developpe applications ? 2. Go is expressive. If we compare it to the functionnal languages, it is not expressive at all.

[@Wingnut353]

In C and C++ there are many ways to skin a cat... in Go there are no cats only Gophers but the same ideas can be expressed. It comes down to efficacy, as languages become more complex they may seem initially more expressive as their vast amount of concepts overlap more with concepts we already understand, however the complexity makes them less effective.... a simple language that can still express the needed concepts will inherently be more effective. What use is expressiveness without efficacy?

"If a language has too many features, or even more than you might need, you spend time programming thinking about which features to use. If there's really a lot of features, you may look at a line of code, write it one way, 'Ooh I could use something different, I could use this feature, I could use that feature...'. You might even spend half an hour playing with a few lines of code to find all the right ways you could use different features to make the code work a certain way. And it's kind of a waste of time to do that. But worse, when you come back to the program later, you have to recreate that thought process. You not only have to understand this complicated programming language doing whatever it's doing, you have to understand why the programmer, who might be you, decided that this was the way to approach the problem from the feature set available. And that is just, I think, bad engineering. The summarization of this is 'The code is harder to understand simply because it is using a more complex language.'

[@jgoodman75]

"Go is not like other languages" Sure Rob...

[@roberthickman4092]

I strongly dislike the phrase 'simplicity hiding complexity'. What is hiding the complexity is abstraction *NOT* simplicity. The best explanation of this I'm aware of is Rich Hicky's talk 'Simple made easy and I'm not going to try to duplicate that here. Common language conflates the terms ''simple' and 'easy' and this usage is not simple. Abstraction creates an illusion of simplicity but often fails in subtle ways, the law of leaky abstractions.

[@crownstupid]

The Hickey video is very interesting and thank you for the reference, but I don't think the law of leaky abstractions applies here. Just because something can (and will) break destroying your beautiful abstraction, does not mean that your abstractions cannot provide simplicity to your users. From Hickey, simple means "unentangled", not interleaved and not braided.I totally agree. I would temporally coupled to that list. I would throw pike's usage of orthogonal right into Hickey's talk about simplicity. I think there's a lot of agreement here, although Hickey has obviously thought quite a lot about this topic.

[@edwardrf]

Abstraction hides the implementation details, not complexity. Bad abstraction can easily create complex interface. Good abstraction is one of the ways to achieve simplicity, but not he only way. One of the other way is conscious feature omission, the philosophy of not having things, or having just enough things. One example is the 1 or no button of the iphone design, that deliberate omission of buttons is a deliberate choice, that achieved simplicity, but doing it right, is complicated, and there is a huge load of complexity hidden behind that one seemingly simple button.

Go is the most well-balanced language ever created.

[@LeonoraTindall]

I really don't think most of these points are valid. A real type system - that is, one with sum types and generics - is not just "more fun to play with". It allows you to verify the runtime behaviour of a program at compile time. In other words, if your program compiles, it is very unlikely to break at runtime. Furthermore, Rust has demonstrated that it is very much possible to have a lot of very high-level abstractions with no cost at runtime.

[@technicalmachine1671]

If you want Rust then use Rust.

[@ggpol]

That was not the point of the comment though. Rob here oversimplifies.

[@ggpol]

But I think that Leo argues about the benefits of generics. The point is that generics do offer something more than just "fun to play with". Rob oversimplifies in his talk what some features have to offer. Prioritizing simplicity is one thing (and quite valid) but putting generics in the "fun to play with" bucket is another.

[@edwardrf]

I think the talk explains exactly why generics is not included in the language, it is a conscious decision, to keep the language simple. I agree generics is a powerful tool, but if you followed any of the several serious discussion of adding generics to go you will realize how much complication each way of implementation would bring to the language usage. If you think the go team dismiss any language feature just because they think they are only "more fun to play with", you are very wrong. And if you feel go is not providing the features you need, there is always rust/java/python/js/erlang... no one is forcing you to use it.

Comparing Go to Rust doesn't really make sense since their problem domains are different. More to the point, while Rust has high-level abstractions that come at very little runtime cost, they come at an extremely high "write time" cost. The average programmer can learn Go in about a week, because the abstractions it uses are simple. You will not be learning Rust in a week.

Haskell is unique, it does add features that are inline with Haskell's design, Python is simple and occasionally add features to continue to evolve. Golang is "unique" and "simple" compared to C#, javascript and swift, what a low bar.

I came here after hearing about Rob Pikes arrogance and eliticism being the reason Go is stuck in the 90s. I wasn't disappointed

+Siddhesh Rane Yeah rust verbosity is better ! Like a fucking loop keyword and this shit like // impl What is this shit to write { x: &'a i32, } impl { fn x(&self) -> &'a i32 { self.x } } fn main() { let y = &5; // this is the same as `let _y = 5; let y = &_y;` let f = Foo { x: y }; println!("x is: {}", f.x()); }

Arrogance and eliticism? Did you watch the same video? He made excellent points and supported them. What do you have to support you, internet rando?

[@kobac8207]

16:04 says "three strokes", shows two fingers. Same as the "simplicity" in Go. I can understand he wanted it to be simple and readabe, but made it pretty much the opposite. For loop instead of map/filter and at the same time talking about the readability of Go?! Come on 🙂 Two words that explain his thinking and Go itself: wanna be.

[@ColinFox]

Well, as someone who actually works in go, I have to say that you're wrong. I love working in Go, and find it the most readable language I've ever used, which includes assembly, basic, python, C, C++, C#, Forth and others I've forgotten by now. What language do you think is more readable than Go?

[@astantine85]

An uninspiring language by an uninspiring team.

[@jumpman120]

+astatine85 Golang used for Docker, Hashicorp and Kubernetes and Google et cetera ! But yeah golang is uninspriring

[@ColinFox]

I think that's your own personal sour outlook. I love Go and find it quite inspiring, as I do the principals involved like Rob here.
