Re: Slide V08_page 33_Continuations example

I think it doesn't at all. At least I wrote in my slides, that the result is just 'done'.

Re: Questions slides/code 1-5 + 'Intro to Scala'

Thank you!

concerning question 5) again:

I wanted to know the difference between call-by-name and call-by-reference. From what I found on the internet, I thought they should be the same: The thing we did with the EClosure, right?! Or what is the difference?

Questions slides/code 1-5 + 'Intro to Scala'

Hi there, I collected the questions I have for the first few slide sets. Here goes: 1) 'Intro to Scala': trait is described as similar to interfaces in Java, but with state and fields. So it is actually nearer to an abstract class, right? 2) Slide 2, p.27: Typo in case Num(n) => expo instead of expr...

Slides 11 not online

Hi there,
am I mistaken or are we one slide-set short? If so: Can they be uploaded?
Best!

Re: Assignment 9: BindCC Usage

That (dropping short-circuit evaluation) works for me too.

Re: Assignment 9: BindCC Usage

Yeah, thank you! Ok, then can you explain why test10 and test16 should return what the tests say that they return? 'Cause for 10 I would assume And(true, BindCC('k, Or(true, App('k, false)))) => And(true, Or(true, App('k, false))) => And(true, Or(true, false)) => And(true, true) => true != false And...

Re: Assignment 09

That is how I solved it (tasks 1 and 2 complete). Anything other (as you already said) does not make sense.

Assignment 9: BindCC Usage

Hi, I don't understand how BindCC should work. Maybe on the example of test10, can somebody explain how this is evaluated? runInterp(And(true, BindCC('k, Or(true, App('k, false))))) It is said, that we should bind the body (Or(true, App('k, false))) to the param ('k). Recursive binding makes no sens...

Zertifikate am Fachbereich

Hallo, folgende Frage: Was gibt es denn für Zertifikate, die man hier am Fachbereich machen kann. Ich habe bisher nur näheres gehört zum Tester Zertifikat aus SE 2 (ISTQB). Aber da gibt es doch noch sicher mehr. Kennt ihr welche? Gerne auch mit Infos, ob man dafür einen bestimmten Kurs besuchen muss...

Re: Matching not working

Thanks, that explanation would have been nice to have in the task description...
Mind you, that not everyone in this course does know the tweaks of Scala and researching this makes the task so much more time-consuming. :(

Matching not working

Hi, I can not see, why this shouldn't match, but it doesn't: I have maybeMethod= Some(Method(New('Dummy,WrappedArray()),WrappedArray())) but when matching maybeMethod, it jumps straight over case Some(Method(body, params)) to case _. Can anybody explain, why this doesn't work? Also maybe why Symbol*...

Re: Assignment 7: Moving Mark and Sweep

Ok, though I have to say that it is not clearly stated what we are allowed/supposed to change here in the task description. But thank you for clarifying. PS: Will there be a task over the winter pause? It would be awesome if there wasn't ;-) These tasks are getting increasingly complex and it would ...

Assignment 7: Moving Mark and Sweep

Hi there,

am I allowed to further change the method signatures?
(Further as in "the stack is not only passed to mark, but also to sweep".)

Ok, thanks. That worked, though I am not yet exactly sure how, but I'll figure it out :lol:
