After reading many comments from its original authors, it's not surprising.

There's a couple of languages I follow their roadmap and I find exciting, including Java and C#. I don't feel there's proper justification of writing backend services in something like python or ruby anymore, for example.

Visual studio (at least its "core") is written in C++, yet is very heavy weight, so it's not the programming language at play here.

It should address the most common use case for reification. Type erasure has its advantages which we saw in the JVM ecosystem.

> You mean it needs 15 lines whete C# needs one? ;) Can you elaborate? The async/await approach is much more than 1 line when you need to switch a call between them. Whereas the green thread approach does not need anything.

Value types are scheduled to be in preview next release (6 months). And C# does not have type classes.

Nullness annotations are already usable. The JEP is for further integration into the type system.

Golang tried to be simple, but reality hit and they started adding features (generics, and now generics on method, iterators, fixed loop variable scoping). Yet when you program in it, you can feel so much resistance because it took a naive

It hasn't been lingering since they were bought by Oracle. We've seen a rapid increase in the pace of feature and performance development.

Golang is not faster than Java, the opposite in fact. With native image, Java can be used for sidecar applications as well.
13.
by za3faran 11d ago
Many of those are getting addressed. Value types are in the works, generics specialization for primitives, and even type classes.

What better options are there if starting from scratch? The only thing IMO that comes somewhat close is C# for general backend systems.

Golang doesn't have solutions like these: * https://jspecify.dev/docs/user-guide/ * https://openjdk.org/jeps/8303099

Which features exactly? Java got exhaustive pattern matching before C# (through sealed interfaces), it has switch expressions, multi-line strings, green threads and structured concurrency, is getting value types, and even type classes in th

Java can and has been used for real-time systems, but it does not look like the Java that you would come across in normal programs. Obviously, RTOS have specific requirements, which usually rule out GCs and other runtimes, where even "

Hopefully more people start realizing this. It's been happening behind the scenes for way too long, but now it's out in the open, they don't care about hiding it anymore.

CPU is still more expensive than memory. Trading more memory to save CPU (and reduce the # of nodes required to run your service) can still hold.

It's not untrue, there are people who have observed this, and for a long time now. AOT compilers assume a closed world system, whereas JIT are able to perform runtime optimizations that AOT can't. By real world systems, I mean lon

Key is "well optimized". At some point and scale, it becomes almost impossible to chase those manual optimizations, not to mention that usage patterns at runtime can change in such a way that make such an optimization prohibitivel

GraalVM native-image already provides an AOT-only executable.

To be fair, it's not that hard to get an improvement compared to running TS in the backend.

We've seen several anecdotes where JIT languages (e.g. Java) outperform Rust in throughput and latency in long-running server programs.
26.
by za3faran 15d ago
In real world systems, Java can beat programs in compiled languages like C++ and Rust when it comes to throughput and even latency.

Fus-ha Arabic (High Arabic) is intelligible as it is used in official communication, academia, news papers, documentaries, etc. But obviously it is not spoken day to day.

What is more important that those $75 is whether or not the gas offered at the other station is Top Tier grade. Costco always is as far as I can tell. (I am not affiliated with Costco in any way shape or form)

> But I can get gas for $3.62 right now at the station down the block from my house. But is that gas station selling Top Tier[1] gas? As far as I'm aware, Costco always sells Top Tier, and now they're rolling out Top Tier+. [1]
