    Any link to the capstone discussion forum? Cannot see it on Coursera (perhaps same as the Spark course, did not show up until started)
    Philippus Baalman
    @Philippus
    I can see it on the left
    Peter Johansson
    @ironicpgm_twitter
    Yes, thanks, that works. I have not payed for the course, maybe that is why I cannot see it before 2 April

    ... I thought that you could only access the scala-capstone if you pay ?

    @ironicpgm_twitter
    @sernle No, you can do it, but no certificate.

    I've got a problem submitting the week 2 assignment (and a bug report to go along with that), when I try to submit the assignment I get a token mismatch
    submit tells me
    [info] Attempting to submit "stackoverflow" assignment in "bigdata" course
    Julien Richard-Foy
    @julienrf
    When did you refresh your token?
    Martijn Hoekstra
    @martijnhoekstra
    which seems to be the right thing
    but then the response is You used a token for "StackOverflow (2 week long assignment)" in "Big Data Analysis with Scala and Spark". Please use a token for the assignment you are submitting.
    the bugreport to go along with it is that the response fails to parse correctly
    yeah, I refreshed the token a bunch of times
    sbt also tells me it's trying to submit the right assignment on the first line

    @julienrf
    can you show me the content of your build.sbt?
    Martijn Hoekstra
    @martijnhoekstra
    it's unedited from the downloaded version
    I chose a bad time for a synchronous channel, I don't have my assignment here :/

    Anyone who used homebrew to install Scala? I cannot find Scala SDK with Intellij
    Han van Venrooij
    @irundaia
    I've used homebrew to install scala. But I think IntelliJ downloads its own version of the SDK
    Anton Yalyshev
    @yalishevant
    @TaoOfCoding if you install Scala via homebrew, default path of SDK for IntelliJ should be like [/usr/local/Cellar/scala/2./idea]. The finder won't show directories like /usr etc. A workaround is to temporarily add this folder to the shortcuts sidebar in Finder (open a terminal and run: open /usr/local/Cellar/scala. This will open a finder and show the idea directory. You can drag this to the shortcut sidebar.).
    In IntelliJ go to Project Structure -> Global Libraries -> New GL (plus sign) -> Scala SDK -> Browse -> choose [/usr/local/Cellar/scala/2./idea]. This way works for me. But usually I use SDK that IntelliJ proposes to download.

    Hello - First post! I'm on week3 of Functional Programming in Scala, and having a hard time trying to follow along in the videos using IntelliJ. I can't figure out how to get Rational.scala and scratch.sc set up so that I can use package week3 and import week3._. In Rational.scala I have no warnings, but in scratch.sc I get a warning that "Package names doesn't correspond to directory structure." My project is setup like this: progfun/src/main/scala/week3 where week3 is a Package in IntelliJ, and Rational.scala and scratch.sc are Scala Class and Scala Worksheet, respectively. Has anyone here run the examples from the lectures in week3 in IntelliJ can help me get this working?
    Martijn Hoekstra
    @martijnhoekstra
    maybe give it a try on the coursera forums if you don't get anything useful here @charlesmims - I'm not an IntelliJ user myself, so I can't help you out, but I don't see anyone else stepping up (yet?) either

    Just now ended Scala Specialization, it was really awesome!
    It took about 1 year for passing all courses parallel with working and studying at university.
    When I started this specialization I didn’t know much anything about Scala and now I’m working remotely on a very good job as Scala Developer.
    I want to say 'thank you' for your work: @heathermiller @julienrf and all EPFL Scala team, thanks!
    Julien Richard-Foy
    @julienrf
    Thanks for your kind words :)

    Sorry for the question, I'm new to the coursera, I can not figure out how to send my homework (it's written run the script sending the work from the download package), which script to run? I will be grateful for the help

    I believe I have found a problem with the assignment for Week 2 of the Functional Programming Principles in Scala course on Coursera. who do I talk to about this?
    Julien Richard-Foy
    @julienrf
    Me :)
    What’s the problem?
    Nth/April
    @NthPortal

    it asks you to implement:

      /**
       * Returns a set transformed by applying `f` to each element of `s`.
       */
      def map(s: FunSet, f: Int => Int): FunSet

    however, you cannot actually correctly implement such a set using f. you need the inverse of f (which may not even exist, e.g. for _ / 2). you can hack it together by iterating over some subset of the domain, as is done with forall and exists, but that is not a completely correct solution/implementation, and also should be documented as needing to use the upper and lower bounds if you need to do so

    Julien Richard-Foy
    @julienrf
    You are right.
    We should document that an incomplete implementation is fine (ie, works only for values within [-1000, +1000])

    Martijn Hoekstra
    @martijnhoekstra
    :/ that sounds pretty questionable.
    Nth/April
    @NthPortal
    it's what's used for forall and exists, so it's at least not new in that respect
    Julien Richard-Foy
    @julienrf
    Actually, the goal is to implement map in terms of forall or exists, but this wasn’t clearly specified in the instructions
