The article has nothing to do with Haskell, other than it's what I use. Why should I have to justify that when I want to talk about architecture diagrams? Would the same expectatio…

Oh are you intimately familiar with Atlassian's systems? Marketplace is Atlassian Marketplace, a real website, REST API and bunch of frontend components. If it's not part of an arc…

I've used it a bunch. It's pretty good! I think the Java API could use more types and less mutation but it works well.

I don't often show architecture diagrams to non technical people BUT I also definitely don't show most technical people this Haskell code. I also don't show them the PlantUML. I sh…

Atlassian Marketplace's architecture diagrams change constantly. Altassian replaces a core system, we have to integrate with a new one, we rewrite or replace a system. Did you read…

I didn't mention it, but I do write architecture diagrams which have input. data Version = Current | Future generate :: Version -> Diagram Implementation uses a few if/else express…

Hey everyone, I'm the creator! Sorry for the problems - I was hotlinking to the awesome http://rawgit.com/ website during development and forgot to remove it before posting it on T…

No processing necessary. Just upload JSON. The Quirrel language is much more high level than the API for ElasticSearch. It comes with things like machine learning (e.g. clustering …

I worked on Precog. Here's my explanation: It's an analytics platform for big data. Basically, you upload lots of JSON, use the custom language ( http://quirrel-lang.org/ ) for ana…

TDD increases the chance that more people will mock Absolutely false. Try TDD in Haskell. Know how many mocking libraries there are in Haskell? None. Totally unnecessary.

It's too slow. Now what? You have to use asymptotic analysis to figure out that it's O(n^3) but can actually be performed in O(n) - then write the derived code from your analysis. …

Author here. I use Haskell for a lot of webapps. Here's a webapp that talks to GitHub: http://licentious.herokuapp.com/ https://github.com/pufuwozu/licentious Here's a programming …

Did you read the conclusion of TFA? > Analysis is the method for writing code that satisfies our constraints. Neither TDD nor types are the single answer to writing code that does …

From what I can tell, Bryan mostly works in Python and C at Facebook.

Even GHC's (Haskell) REPL executes side-effects.

Exactly. The promises spec defines the Promise monad. The problem is that JavaScript doesn't have monadic syntax, which would make the code a lot more readable.

As a creator of an "altJS" language, I've been thinking about this for a long time. I wanted a VM in the browser for years and was a huge fan of Silverlight/Moonlight but I recentl…

There's a way without exceptions. Use an ErrorT[Promise[A]] monad. I've done this in Scala before and it is so much simpler than the JavaScript convention you pointed out. It allow…

Thank you. It's really quite depressing to visit Hacker News and see it filled with people being unopen to intelligent ideas to make things better.

Yes. Elm is a FRP language that compiles to JavaScript. View source on some of the examples: http://elm-lang.org/Examples.elm

Callbacks are different than gotos in that they are aren't even remotely close to gotos. The analogy is that callbacks create non-linear control flow. Using a monadic syntax like i…

That checking is by definition, not type safety. What you're talking about now is totality. Both Haskell and Clojure allow non-total functions (functions which may not return a res…
