I get what you're saying and I don't really disagree with you. An object's methods are an interface and its method signatures are a contract about what "messages" (in Alan Kay parlance) it will accept and return. A

Well, Java 8 isn't really "new" anymore. :) But, I was complaining about the 8+ DateTime API. Now, granted, it's WAY, WAY, better than the old API. And it's much better than what's available in at least sever

Yeah, I've read little snippets like that from blog posts and stuff, but I've never written a single line of Ada, so I really don't know how that works out in practice. What happens if you overflow at runtime? A crash, I assu

I understand that there are performance implications. But a 20% to 40% slowdown for number crunching in a language that is primarily designed for writing super indirection-heavy, heap-allocation-heavy, application architectures is just noth

Honestly, I truly don't know and I don't feel qualified to judge the merits of the two approaches. There could be performance or behavior implications that they just prioritized differently from how C# does it. Or maybe something

That's good to hear. Java/Kotlin also have mutexes- just not as language built-ins (well, it does have `synchronized`). They also have a ConcurrentFoo set of collections as well. And actually an ImmutableMap (but I don't see

Kotlin does indeed (mostly) fix null. Kotlin does not fix the issues with checked exceptions. It gives up and gives us nothing for error handling. So, for all the beauty and magic of a strong static type system, I have absolutely no idea if

I don't know about Ada, but I enjoy Rust's strictness when it comes to numeric types. > Java-style wrapping integers should never be the default, this is arguably even worse than C and C++’s UB-on-overflow which at least permit

by ragnese 6y ago
My opinion is that a high-level language like Java has no business making me guess how many bytes my numeric values will occupy. It's insane. Since when does Java give a crap about memory space? "Allocations are cheap!" they

It surprises me as well. And to belabor my own point some more: there's a reason the #1 question about Rust from newbies seems to be "Is there a language like Rust, but with a garbage collector?" - sometimes reworded as &quot

Yes and no: https://github.com/Kotlin/KEEP/blob/master/notes/value-class... "value class" is the next step for inline classes. They are going to behave very much like Swift's struct a

I think it's disingenuous to deflect by saying that Scala didn't invent those concepts. I think it's pretty clearly significant that Scala and Kotlin are JVM languages, specifically. If we just said "Well, StandardML had

If I remember correctly, it's fairly easy to use @Nullable and still end up with nulls there, even without an IDE warning. I'll have to double check to see if I can still reproduce that. But, to be fair, it's actually fairly

The hype around Rust is largely justified. There. I said it. Rust is nowhere near perfect. It's also supposed to be a systems language- it was probably not originally intended to replace languages like Java for general "app"

I disagree that it's a lovely language. I think, as developers, we very quickly develop Stockholm syndrome. Once you "learn" a language, it's really easy to churn out code and apply idioms without even realizing that you

I agree with your points here, but just want to add that, while Java's generics are better than the non-existent generics in Go, I still find Java's type system to be really subpar for today's era. The type system is not stro

But those inits don't actually DO hardly anything. The Rust one hardcodes a bunch of stuff and has "TODO - setup signal handler" in the code... You're not even comparing them to just the init part of systemd, but the ent

I definitely understand that criticism w.r.t. all of the systemd-verse replacement tools. I'm not an expert. I'm just a software dev and free software nut who wants a free software OS. But (serious question), why does it matter th

That's a fair point, but where is the line? Do sysadmins worry about debugging Linux? Should it be written in Bash so that they can (obviously the kernel can't be written in Bash, but for the sake of argument)? As a non-sysadmin

I was very disappointed in the portrayal of "Christopher"! They have him say "boy" but they never clarify that the "boy" was 19 years old. I have little doubt that some people left the movie thinking that Turin

Agreed. Before I was done watching the very first scene of that movie, I had my phone out because I thought maybe I didn't know he had ASD. Nope. He didn't. Just the way pop culture likes their nerds to act.

I definitely agree that I don't want a "Linux phone". I just want an open-as-possible phone that isn't 100% user-privacy-hostile. I couldn't give two flips if it is the Linux kernel that accomplishes that, but I thi

Okay, fair enough. I probably skimmed the post too quickly.
