But arguably your intent would be much more clear with something like `map (printf "%d %d" m _) ns` or a lambda. I don't think parent is saying that partial application is bad, far from it. But to a reader it is valuable i

Jokes are only funny when they have an ounce of truth to them. Oracle was the one who open-sourced the whole of the JDK, and is the main contributor to OpenJDK by far, which is completely open-source with the same license as the Linux kerne

But you only need to do that before a release. You can just develop with the normal JVM with ultra fast incremental builds and hot reload.

Well, Android is not running Java, it runs Android runtime (dalvik) byte code. In general, depending on when it was, that runtime is much much simpler and does a lot more at compile time at the expense of less JIT optimization. It's al

Not sure why you are down voted. Depending on how its used it could actually be detrimental to performance. The JVM may optimize many short lived objects better than a pool of objects with less reasonably lifetimes.

> all optimizations You might want to take a look at what actually happens here. The only reason Go can compile this fast is that it does barely any optimizations. And yeah, javac also does a literal transfomation to Java byte code, no d

I am fairly familiar with FP concepts, though lack experience with large FP-only code bases, so I don't think the OOP-blinder things apply to me. Visitor pattern is meant to address the other half of the expression problem - you have n

It's not a good core abstraction for a build tool to not be able to do proper iterative builds. And thus it's not a good model for IDEs neither, while with Gradle it never gets out of sync, with Maven it can easily happen that som

Even Rust has a runtime. Compared to that Go's is absolutely fat though.

It's just that Maven doesn't have a good core abstraction and it is not a reliable build system. Like even with base plugins, let alone with additional ones you can't be sure that a build actually picked up every change, you

Unless you are using a strictly FP language, you are always basically using objects. And all the stuff like factories and everything exist in FP as well, it's pretty short sighted to say otherwise. These are patterns that may or may no

With all due respect, I'm fairly sure that anyone using "VM" the same way as you do here really think of it as a container or what. It's a runtime, and go also has a similar, fairly fat runtime. It's just burnt into

I wouldn't use application servers today, but they were solving many of the same issues as whole kubernetes clusters do, decades ago. The Java (now Jakarta) EE standard on top is a good base for third party implementations to "spe

And a fat runtime with a garbage collector. Like people can write all sorts of programs with a GC, that was never the issue. But then just stay truthful, otherwise C# is also a system PL.

In what way does that "design" show up in Go, besides marketing?
441.
by gf000 7mo ago
Because almost my definition you can't handle errors in the component, otherwise you would have a conditional and not an error. E.g. if I do some IO like "make a copy of these files" and get an error/exception, it's

GraalVM indeed does a lot more than Go, it's a full optimizing compiler while Go does very little optimiations. But burning a JVM next to a jar file is not hard at all, one could make something like cosmopolitan.

Do you need extra-low latency, even at very high percentile and are willing to give away a bit of throughput for it? ZGC At almost every other case: G1 (the default, just don't add any flags). Do you want to trade off using less memory

Didn't mean to say that syntactic sugar is bad. But when Java touches a language feature they prefer doing it only when absolutely necessary and even then having the biggest part be in the runtime if possible. E.g. in the lazy case, it

Yeah, but you only have to do that before shipping. You can just test/develop with "normal" java, you even get hot-reloading.

Java compiles as fast as go, so not really sure what's the problem - you can basically use it in an "integration loop" with no problem.

So just type classes? How does a type class help with composition? They do help with the expression problem (adding support for an "interface" after definition), and via parametric polymorphism they might give you a bit with regar

I get the snark, but also - there is this "ideal Java code style" that most experienced devs tend towards. Unfortunately I don't see anything like that for Kotlin (yet?), and there are a bunch of patterns that I really dislik
