The Dyalog Problem solving problems are most excellent practice. And fun.
I'm finding they get easier with the years, but hopefully that's me improving rather than them actually being easier.

@RGS Yes.

IsPrime←{2=+/0=⍵|⍨⍳⍵}
Adám
Adám
@JeffZeitlin Yes, that's pretty much the canonical answer.

Unless I miss something, that's going to be O(n) for calculation time.
Is there any way to do better?
Adám
Adám
16:51
@JeffZeitlin Yes, a proper sieve.

@Adám my APL kernel doesn't connect :'(
I already have the option of creating a notebook with the "Dyalog APL" kernel but once opened, the kernel doesn't start
Adám
Adám
Hm.
I don't even know where to start trying to debug that.
RGS
RGS 
C:\Users\rodri\anaconda3\python.exe: No module named dyalog_kernel
Adám
Adám
Ah yes, I've seen that error before.
RGS
RGS
says the terminal running the notebook thingy
Adám
Adám

@RichardPark May have some ideas.
RGS
RGS
Do you think it may have anything to do with the fact that I installed anaconda and didn't make it the default for python 3.7?
Adám
Adám
I can't rule it out. Tbh, I never really understood how Python picks up its modules.
RGS
RGS
hm alright; so should I wait for Richard's help?
Adám
Adám
I think that'd be wisest. Of course, you can already now plan then contents.
RGS
RGS
I think I'll try reinstalling and leaving that option I mentioned on; should I "uninstall" your dyalog kernel? Or can I just uninstall anaconda, install again and then install the kernel on top of that?
Adám
Adám
17:05
@RGS I think just reinstalling on top would do. You can look at the installation batch file. It is really simple.
Richard Park
Richard Park
@RGS Do you only have anaconda installed or do you have a separate python as well?
RGS
RGS
I have a separate Python @RichardPark
but I just solved it
maybe not in the best way, but I solved it
Richard Park
Richard Park
@RGS Manually copying files around?
RGS
RGS
yes, the dyalog_kernel into the "correct" site-packages folder
Richard Park
Richard Park
@RGS Yes I've used that "trick" before
RGS
RGS
17:12
I installed some random package with anaconda's pip
Adám
Adám
Can we somehow add that to the bat?
RGS
RGS
checked the folder into which the things were going
and copied the dyalog_kernel to that folder
@Adám I would guess so, I just performed one extra copy&paste
Adám
Adám
@RGS Feel free to PR.

(proof it works :P)
Adám
Adám
Yay.
RGS
RGS
17:13
@Adám sure; should I add the line or replace the one that seems wrong?
Adám
Adám
@RGS I think add, as I remember us having trouble with this before, so we might need to have both destinations to make it work universally.
RGS
RGS
Alrighty
Richard Park
Richard Park
@Adám Yeah it bascially just attempts to copy to all python installation folders we've thought of

@Adám I just want to say I'm sad tomorrow is not an APL Cultivation day
Adám
Adám
19:21
@RGS thanks :-)
RGS
RGS
@Adám when I'm done with the notebook and I want you to have a look, what should I do? Host it on GitHub?
Adám
Adám
19:47
@RGS Sure, that'd work, or you could make it a PR on the existing collection.
RGS
RGS
@Adám ah of course

@JeffZeitlin miller-rabin is a simple and efficient primality test that doesn't require sieving
RGS
RGS

@Adám I also PR'd the notebook I created. Let me know of all the feedback you have; from major problems/adjustments needed to the minor details.
Also, how did your yearly appraisal go..?

@dzaima another one, imo much worse/annoying than the others, but for the exact same reason
