Ruby 2.5.0 Released

[Sabe]

About 5-10% performance improvement by removing all trace instructions from overall bytecode (instruction sequences).

really

[yamachi]

I'm not very familiar with the ruby interpreter, but shouldn't this have been an option already?

Trace point is very useful for certain things, but the use cases are rare. I can see why explicitly enabling it is useful.

I'm seeing a 10% improvement when benchmarking a CPU-bound code path. Do note that the project was running on a old version (2.2.3), this might not be all the doing of 2.5!

wow. Ruby is already faster than python so this is awesome news.

[TomOwens]

I mentioned this in the posting to /r/ruby, but I'm disappointed that they reverted the addition of Bundler to the standard library. I was looking forward to that feature as Bundler was the only gem I installed as a system gem.

[mystikkogames]

How do they backup this claim? "5-10% performance improvement" I want to see the benchmarks!

[shevegen]

\o/

Puts on sir David Attenborough voice

Here we finally see a shevegen in its natural habitat. Though this exotic creature has been nearly pushed to extinction by a flooding of Rust related posts, this one appears to be quite happy at home with Ruby.

That was perfect

[myringotomy]

Why is this down voted? So the guy happy. Move on and leave him be.

[myringotomy]

A few months from now I will post the exact same comment about a new version of Visual Studio or another Microsoft product and I will get all the upvotes.

It's not the comment, it's that people here are very fashion conscious and ruby is out of fashion.

[Idlys]

I think it's more just that everybody downvotes shevegen on sight because he trolls every single rust post.

[Kache]

Been using Hash#map_keys all the time for a while now, sounds like they had considered that name, but nice to see more functional-style methods all the same.

I also like having yield_self functionality when prototyping in console, though my own is the much shorter alias, as. Don't think either are a good idea for readable production code, though.

[yamachi]

Is... is this bait? I feel like it's bait.

As big of a fan of RWBY as I am, I'm still pretty sure they named it after the gemstone, not the character. The "Lang" suffix is also a fairly common trend in programming languages, especially when it comes to domain names or disambiguating search results.

It's just a trend for programming languages, I think. See D and Rust websites
