I think its actually easier than go.

Goroutines are cool, the rest of the language is utter shit.

>The key point here is our programmers are Googlers, they’re not researchers. They’re typically, fairly young, fresh out of school, probably learned Java, maybe learned C or C++, probably learned Python. They’re not capable of understanding a brilliant language but we want to use them to build good software. So, the language that we give them has to be easy for them to understand and easy to adopt.

>>61626973
>I think its actually easier than go.
The language itself yes, but writing good C, without dangerous bugs is harder than writing Go without said bugs.

it's because of your negative IQ

Go is compiled, so it's fast. It has concurrency in language, it has a great standart library and very suitable for server applications.

it's also very small and simple and very modern.

it has automatic memory management, it's statically typed, it's perfect.

hi robert!

C is faster, has a good enough library and is more suitable for server applications. It's also smaller, simpler and fairly modern.
It doesn't have that bloat, it's also statically typed even if dynamic is the future, it's literally better.

>>61626901
Why not just make function takes as parameter varidiadic amount of functions and if one of them returns err != nil then you execute function related to that and if you don't want to go any further you stop there just like && statement.

Go is shit, but it's surprisingly efficient for HTTP traffic.

>>61627098
hi pajeet,

C is faster, sure. Has a shit standard library but not an issue, because almost every language is written in C anyways.

----

It's not that suitable for servers. You can use OS objects like, epoll, kqueue or IO complation port in linux, bsd, winnt respectively and write the fastest servers of all with a good architecture.

however, there are things, very important for servers.

1) a server should run months or years without restarting. so the language should be safe, dangling pointers, null references etc an issue and servers written in C exploited too many times.

2) you have to keep track of memory very carefully, even 4 bytes of leak will add up because you don't restart server. manual memory management is more dangerious.

Go solves all the problems mentioned. Of course you should have some brain, otherwise no tool can save you.

----

It's small, simple but not modern. String handling and manual memory management is a huge pain in the ass.

----

dynamically typed languages have their place, but they are not suitable for big programs, you have to be much more careful. it's just too dangerous for server applications.

C is master race but Ken Thompson is literally the founder of C and Pike wrote more C than all this board combined.

So they created Go, you have to respect it.

Dumb picture. Firstly, that first pic is not before Google. Secondly, his wish for a computing environment with no local storage etc is what he did with Plan 9.

Go is going to replace Node for API based backends. The fact that Node uses callbacks that queue up to a single event loop to fake concurrency is a very weak and fragile way to run a server. Go uses real non-blocking threads. The syntax for Go is very clear and easy to understand, much unlike the spaghetti of nested callbacks that you have to use to make Node work. The fact that the server is built into the language makes Go backends even more easy to use as you dont have to import a ton of middleware to make things work.

>>61627903

yes, it will not compile, and it shouldnt, that style takes up too much space and is hard to read. I love how when I hit save in my editor the Go plugin auto-indents, I actually catch a lot of small errors when it doesnt indent right.

>HTTP: still 100 lines to get it echo "Hello World"
That's just wrong, assuming you imported a library(read: crate(I fucking love meme names)) look up reqwest.

I'm not saying Rust is the end all be all of what ever I don't remember. But they cater to people who would rather import some library from an insecure source, rather than import a library that has been peer-reviewed.

Rust claims to be safe, secure, and "if it compiles it doesn't have bugs", I say, Rust is gonna be the next source of a Left-Pad bug, because people who use Rust rely on the compiler telling them what is wrong, rather than reason about it themselves.

>>61629150
It's either just another Lisp shill who thinks functional programming is the future or a C++ guy who absolutely wants his language to have as many confusing as fuck "features" as possible because it makes him feel more organized.

>>61629097
The reasoning they give for not including generics is almost wholly technical; they're trying to maintain fast compiler speeds and low runtime overheard. Every implementation compromises on one or the other. It's not about accommodating users; you can see whenever this subject comes up many people are actually too dim to program well without them and are driven away.

The designers summarized the reasoning why there are no generics in go currently. 4chan for some reason won't let me post the google docs link so I'm stuck posting an HN link I found in duckduckgo: https://news.ycombinator.com/item?id=8756683

>>61629280
>and low runtime overheard.
Reified generics cost less at runtime than having to typecheck everything as with type-erased generics or no generics.

>>61629267
I have a hard time believing their main concerns are compile and runtime overhead when the proposed alternatives in your link is copy-pasting/generating code and using reflection or type casts.

>>61629346
And it extends compile times, which is counter to their goals.

>>61629419
The ways given in the link are just an enumeration of what's done currently, not an endorsement. They identify weaknesses in all of them. The reason go is what it is now is because they've opted against making the tradeoffs involved and have passed it on to the users for the time being rather than deciding for anyone.

>>61629346
They also add significantly to compile time. It's funny that armchair language designers think there's no argument to be had when even people like Chris Lattner, Slava Pestov, Andrei Alexandrescu, Lars Bak, Anders Hejlsbergand, Erik Meijer have mentioned that they're still unsure if the trade offs for generics are worth it. It makes the implementation much more complex and makes a lot of optimizations much harder to implement because they have to be generalized and have escape hatches. Languages with unrestricted subtyping make it even worse.

The ecosystem is not going to happen no matter how hard they work on their "crates".

Also the Rust activism is turning people away from it If you can't advocate for your language without basing everything on features that exist in better designed languages (Ada2012) you're wasting your time. No one will switch to Rust for muh safety.

Errors are values in Go. They're returned from functions that can fail. After each potential failure, you should check if an error occurred, and then handle it somehow. Your program's control flow is explicit and immediately apparent from reading the code.

A lot of things can return errors.

The ability to simplify means to eliminate the unnecessary so that the necessary may speak. — Hans Hoffmann

Complexity has nothing to do with intelligence, simplicity does. — Larry Bossidy

Simplicity is hard to build, easy to use, and hard to charge for. Complexity is easy to build, hard to use, and easy to charge for. — Chris Sacca

Such is modern computing: everything simple is made too complicated because it’s easy to fiddle with; everything complicated stays complicated because it’s hard to fix. — Rob Pike

>>61632317
>D is big
Very true.
>Better C++
It's a better C++. However I will ditch D if there is an actual better C++ with RAII, templates and some functional features that has no GC or source level C compatibility.
Unfortunately, there is none. Rust was close to it but then it fucked shit up with unnecessary traits/lifetimes/borrow-checker overhead (for programmers)

However, Go is not productive at all.

>>61632242
Dijkstra didn't like the C family of languages and definitely wouldn't have liked Go.

Towards the end of his life he loved the ML family of languages. They made good choices and are relatively simple yet still powerful. Go is simple but made incredibly poor choices and because of that it's extremely inflexible and constraining.
