Ruby can’t beat Java..that is the fact. We can’t say that ruby is a language because it is not a language but just a script. However, ruby is faster and easy but not suitable for medium to large application.

Yes your totally right. Ruby programmers are so ignorant. I mean that is why they came up with things like Yarv and JRuby because they had no idea that Ruby was slow and no idea that interpreted is faster than compiled. Stupid ruby programmers!

Ruby and Java are languages, and they are not by themselves fast or slow. PLEASE TRY TO UNDERSTAND THIS

Implementations of languages (aka Virtual Machines) like MRI, Java HotSpot or JRuby can be faster or slower.

That said, claiming that Java is more scalable that ruby just because one implementation of that language runs code faster than another is plain stupid.

Yeah, your code might be faster, but you are creating applications, not running a fibonnacci number generator, so bottlenecks are (almost always) in other parts of your application, like databases or web servers.

Seriously? Is this conversation happening? The original article was remarkable in how poorly researched it was and to be having language wars over things like generated code is simply hilarious. Reading it and these comments is like being transported back 2-3 years.

Yet Another Java Guy brings shame to his community. And I’m blown away that there’s so much seething over rails by java folks.

I’ve worked .NET, Java, Cold Fusion, ASP, etc. I’m currently a ruby guy. Every language/framework has its issues to think otherwise is delusional. One place I worked underlined it perfectly. We had Spring MVC and other Java sites that took forever to build and were a pain in the ass to change but once up they were up for life (while taking 389 megs of RAM. No more, no less). On the other side they could churn out multiple Rails sites (meaning more revenue) in the same time as one Java one (same programmer on both sides, originally a Java guy). However the caveat was that some would end up being unstable (code quality issue likely) and could take anywhere from 40 meg to 1gig depending the leakiness of libraries used (haven’t seen this in a long time). But we could take client requests for changes to their sites and turn them around in a very very short time too.

For these sites things like high end scalability of a framework or language implementation really didn’t matter. Getting it to market faster than anyone did. Even 37signals (maker of Rails) doesn’t use Ruby for latency sensitive tasks (they actually just moved from some C based pollers to Erlang ones and reduced the amount of processes running from 240 to 3 - even Java would have been far too slow for the task).

In the end it’s what’s appropriate for the task at hand and for the team you have. There’s no superiority to be had here. Ruby and Rails have benefited from many things in the Java world (hell there’s even a JVM ruby interpreter), likewise Java has benefited from many things in the Ruby and Rails worlds.

For me - Ruby, and Rails floats my boat and reminded me why I got into this business after having the life sucked out of me using some of the leading languages/frameworks (which still have their uses just not what I was needing it for).

What floats yours?

Does it got to do with male hormones?

LOL

By the way, the two developers of JRuby were hired by Sun a year or two ago!

Yeah, that’s all superficial… but it can nonetheless provide clues.

Look, Java is fine. If it meets your needs of your organization then use it. Ditto RoR. Now, after having done Java for the previous 7 years I recently started a gig that is doing RoR and have to say that I’m very pleased. BUT I refuse to get religious about it and go the typical “LOL my language/framework rules and your an idiot hurrr” route that seems so typical.

I like RoR. I also like Java. I prefer RoR right now. That may change.

My life for PHP!

Buwahahahaha!

Besides Java…

dollars

and not all my functionsss

please call it Rails. RoR is a hideous initialism.

But lets talk about the bottom line —
how much do you earn? As far as I know
I earn far better than Java and PHP devs.

You know which is better if you
are well paid, right?

I think Brandon Ferguson said it the best.

“For me - Ruby, and Rails floats my boat and reminded me why I got into this business after having the life sucked out of me using some of the leading languages/frameworks (which still have their uses just not what I was needing it for).

Rails floats my boat Brandon, thanks for asking.

So to all the people that are just plain hating because they are ill-informed or have had your boss shoot down your proposal to start using Rails, just stop. It’s embarrassing.

Every language/framework has it’s drawbacks, performance issues, and quirks that make it unique. I know this war will rage on, but let’s not forget that each language/framework has had it’s success and failure stories, and the most important thing of all, your code is only as good as you write it. Thanks.

From these comments it sounds like a bunch of off shore [Indian Java developers] are afraid they might have to go through another […] course in another language so they can over bill and under perform in yet another language. Stick to Java and PHP. […] P.S. Eclipse is a piece of shit.

I am sorry I’ve let it detoriate this far. Comments are now closed. I guess we still haven’t evolved from a few years ago, what a shame.
