@Finn Thanks, setting it directly above the ENTRYPOINT didn't work either but the -e command option did it.

I will not be able to attend today at 17:00. If my solution is something different from what has been posted, I will send it later today.

no worries

Editing a dockerfile and then running it can go wrong in so many ways ... can you say more about how it "does not work"?

I assume he just doesn't get a 2G ws.

> Given a word or a list of words, return a Boolean vector where 1 indicates a word with one or more consecutive duplicated, case-sensitive, letters. Each word will have at least one letter and will consist entirely of either uppercase (A–Z) or lowercase (a–z) letters. Words consisting of a single letter can be scalars.

So, this problem is almost trivial, the actual work consisting of normalising the various valid inputs.

(∨/2=/,)¨⊆

Yes, that's equivalent to what I had.

One of my two was just with 1∊ instead of ∨/ — not sure why, actually.

@rabbitgrowth Challenge for you: Do it without parens.

Heh, we can do it in "Perl" instead: (⍬≢'(.)\1'⎕S⍬)¨⊆

I don't really know what more to add to this. Handling length-0 words?

That's pretty simple too: (∨/2=/,∘'_')¨⊆

Since we know words won't have underscores.

And if we want to keep it case insensitive?

(∨/2=/,)¨⎕C∘⊆

The two adaptions can of course be combined.

Anyway, this was simple. Next week is 2019:6: Telephone Names which should prove much more interesting!

@Adám can't do it :(

@rabbitgrowth ∨/¨2=/∘,¨⊆

Basically, loop-unrolling.

ah I see

@Adám Why'd you call that unrolling? I'd say that's more splitting the loop than unrolling

Yes, you're right.

@MortenKromberg As Adam said, when it doesn't work I don't get the WS size I want and run into WS FULL.

@phantomics I just tried with a Dockerfile with the following two lines:

FROM dyalog/dyalog:latest
ENV MAXWS=2G

When I start APL, MAXWS is 2G. So I'm puzzled that it does not work for you.

@MortenKromberg I'm apparently using a different Docker config, mine comes from github.com/Dyalog/DyalogDocker/blob/master/Dockerfile and it doesn't have a line saying 'FROM dyalog/dyalog:latest'

Right, that Dockerfile should be what defines dyalog/dyalog.

Unfortunateley dinner is on the table, gotta run

Thanks, the CLI argument worked in any case

The FROM and ENV should be the same as extending the original Dockerfile with another ENV. If you send me your modified file I can try to take a look, but it may not be tonight.

I see, it would go in a new Dockerfile, I'll give that a try

Based on things that have gone wrong for me in the past, my guess would be that you are not running the container that you think you are. Double-check how you tag things and start them up.

Is there a way to query the WS size from inside Dyalog?

⎕←2 ⎕NQ '.' 'GetEnvironment' 'MAXWS' ⍝ Queries the setting
2000⌶16 ⍝ Returns the current max allocation (which MAY have been reduced from MAXWS under program control)

Ah, cool. I was wondering about envars in general. Why is return value output suppressed on `2⎕NQ '.' 'GetEnvironment' 'whatever'?
