They are similar in outcome. Do u care about what language Amazon uses to write S3? Do u believe it is the language that make S3 succeed, or fail? Even as a programmer, as to the other services I am calling, things I do care about involving their stability and correctness that affecting my work. I care shit about what how they write their service underneath, may it be cool or dumb.

If we're going to insist on the carpentry tools metaphor ... hammer vs nailgun; a hammer can do everything a nailgun can do and more ... but if you're banging together a timber-frame for a house the nailgun will let you get through the task far far more quickly. If you're running a business, and time is money, which tool would you want your carpenters using for this task? If I'm running a business that lets say develops an ecommerce platform I won't be too impressed if my developers are using assembler. Java good, but if Scala gives them an edge and cuts my costs so much the better!

  Yeah, so choose what works best for u, not assuming the same thing for others without understanding the specific problems they are trying to solve. Maybe they need a hammer, not a nail gun, because they work in specific environment that don't have sufficient power supply? or for the work they are doing, hammer is good enough, it is better for them to invest elsewhere.

    I'm kind of making the point that in many environments you'll need both? A nailgun (battery or gas powered) for the "bulk" jobs and a hammer for the finer work. I can't imagine anyone being effective in Scala without first having a good knowledge of Java. Or at least without having Java expertise near to hand.

      I used to think so too, but at work I've met programmers who code in Scala without having learned Java first, and it's enlightening. They are proficient in Scala. Whenever they touch Java code, they are upset that the niceties and modern features of Scala aren't there -- whatever we thought was reasonable in Java or "not mainstream" in Scala are exactly the opposite to them. "Why do I have to write all this needless code in Java?", they ask (for example), nicely countering the common but unwarranted notion that Java's verbosity somehow makes code more understandable to regular joes. It's enlightening to me because a lot of what we consider "hard" or "too academic" is actually our own prejudices speaking. Of course it looks like that to us, coming from Java, but try talking to someone who learned Scala first :) I also find it encouraging. Maybe some day we will be able to finally take advantage of the JVM without the weight of Java-the-language.

        You've met programmers who know scala but not java but tell me this: Were they in an environment without java expertise "to hand"? To me scala is more akin to a skin over java. Particularly when using 3p libraries that were written in java (this ecosystem is one of scala's key advantages over other fucntionalesque programming environments). When you work with scala you'll always need some java guys nearby to deal with the "nitty gritty" details.

        No, that's precisely the thing -- I've met programmers who learned Scala as their first language for the JVM (some guys I'm thinking about coded in C and PHP before that), they are pretty proficient, and they absolutely do NOT need Java programmers "at hand". It's interesting that they "get" Scala; they don't try to use it as if it was Java++ (in my experience, this attitude you describe that Scala is merely a "skin" over Java is mostly due to prior knowledge of Java). When these people eventually need to learn some Java, they do so on their own -- and curse the language! I think we're starting to see a new phenomenon: people who don't start on the JVM with Java. It's interesting because it shows (in my opinion) that the whole "Scala is too difficult" thing was mostly a misconception. What it was truly all about was: it's hard to give up old ways of thinking :)

I don't personally care what S3 is built using, but that doesn't mean the people who built S3 shouldn't care. Java, Scala, etc. are all tools with different strengths and weaknesses. Use the best tool for the job, considering the experience and capabilities of the team you have.

Just because end users don't care about the language used to implement S3 doesn't mean the developers at Amazon don't care.

_I_ don't care what they use to write their platform, because it's a black box to me. But _they_ care and spend a lot of time debating it, and that's when discussions like the one in the article are important and shouldn't be dismissed.
