   Marlow is _full-time_ at Facebook, bye bye. There's a difference between being a ghc developer and THE ghc developer. He's more of an advisor now than a committer, look at his ghc commit history, lots of comments, few commits. Not

   Nice find! Didn't know they were so far along with Dotty. Will be interesting to see how a potential merge works out (assume Scala 2.13 at the earliest).

   yup, not sure what Python does with your examples under the hood, but they're equivalent, and, I must say, nicely concise ;-) In Scala I guess we could go zip-style and do: List(1,2,3) zip List(4,5,6) map{case(x,y)=> x*y} b

   No, but Scala encourages FP, so when you: val fooList = List(1,2,3) fooList.map(...) you'll _never_ hit the types of bugs you're referring to. If you fooList(3), then of course you're hosed, but that's not t

   Well, so what? Simon Marlow, Haskell's lead compiler developer in recent years, quit, leaving arguably a much larger gap than @paulp leaving Tyepsafe since SPJ is wrapped up in leading some English education initiative. Anyway, shit ha

   If @1 second recompile entails watching grass grow, you have some serious miracle grow on hand ;-) SBT sub projects are the ticket to sane Scala development. If you just lump everything under a single project, sure, then it's grass gro

   Agreed, Grunt has served me well, much like Bootstrap up to v2.3.2 has, so am in no rush to go looking for the hat on my head. Hands full server-side anyway, client-side moves way too quickly to keep pace with the latest and greatest...

    How do you mean address verification is fairly expensive? Expensive in terms of lost sales (i.e. users giving up in frustration due to mismatches) or something else? We've had AVS in place for years and get reduced fees as a result. Ho

    Thanks for the overview, midway through Learn You a Haskell and it's clear I need to sit down and write some code as reading about Haskell is entirely different than reading about Java, Scala, etc. ;-) In other words, a simple web proj

    That's pretty awesome, sounds ideal for a RESTful API. In Scala I've noticed a tendency toward using NoSQL storage engines like MongoDB, which speaks a form of native JSON (i.e. it removes the BP required to marshall to/from

    I have no idea whether or not the implementation is easier is dynamic languages or not. I do know that for the language user it's a simple foo.to_json, end of story. If you can marshall objects of arbitrary complexity to JSON in Haskel

    There's nothing wrong with language evangelism, if you love the language you work in you'll evangelize it without even thinking about it. Kmett has, I believe, taken on a larger role in Haskell, perhaps officially with FP Complete

    Play framework's a decent gateway drug to Scala, can help you get some of the basics under your belt while seeing tangible results. Otherwise, a book or 2 on Scala goes a long way.

    You're talking about simple 1-to-1 mappings where both db result and case class to json conversion are straightforward. The example I gave was for objects of arbitrary complexity; it's a trivial operation in dynamic languages beca

    Canonical example would be marshelling one type to another, something that typically requires a fair amount of boilerplate in statically typed languages, whereas in Ruby, Grooy et al you just do something like: complex_object.to_json and

    Edward Kmett is a Haskell evangelist (not to mention absurdly productive engineer) so it's natural for him to point out the inconsistencies in Scala, inconsistencies that the average programmer will never even realize exist. He ends hi

    Namecheap allowed me to escape from GoDaddy; for that alone I am deeply thankful. That the transition was seemless and, well, cheap, was an added bonus.

    Good points, I tend to mix it up, rarely going parens-free style, but also not parens by default either. If you wanted to be really explicit you could do: list.filter(x=> isEven(x)).foreach(x=> println(x)) yuck ;-)

    I didn't write what you wrote ;-) foreach takes a collection and applies some function (in this case println). I've actually had a use case for what you're trying do, so created an extension method on Any, which means you can

    Right, which is why ML languages are a bit baffling for me, the ordering seems totally off ;-) Just getting started with Haskell and am having several, shall we say, WTF moments.

    Interesting, in Scala you do: list filter isEven foreach println Which is, IMO, quite elegant, but then again I'm used to Scala and not yet at all familiar with F# and the reasoning behind the syntax.

    Cool to "see" F# in action. Like the union types, but not so much the list operations; seems more natural to: [1;2;3;4] filter isEven sum vs. List.filter isEven [1;2;3;4] |> List.sum in Scala it's: List(1,2,3,4) filter
