The Nineteenth Byte

5:00 PM

Expanding it to include things like AGM, median, mode etc. would make it more useful, but at what point does that start infringing on statistics?

Redwolf Programs

Solution: Change the meaning of the tag and just use it for all challenges which are neither bad nor especially good :p

pxeger

@cairdcoinheringaahing median and mode are arguably averages

Wezl

CMC: Escape an APL string. This means take an array of characters, replace all single quotes with two single quotes, add single quotes on each side, and return an array of characters.

example: that's a lot of damage => 'that''s a lot of damage'

because if you have strings containing spaces or newlines you can't un-split them on spaces or newlines

caird coinheringaahing

@pxeger That's an exact copy-paste of our Sandbox :P

It is a good introduction though

caird coinheringaahing

Not really

SE sites don't have sandboxes for a reason - you shouldn't ask to ask, you should just ask

Unrelated String

6:21 PM

we only have a sandbox because we're not a q&a site at all
here, if you have a problem it should be ironed out before asking
on an actual q&a site, if you have a problem that's why you're asking

hyper-neutrino

ah, another mod got there before I got back to my computer. good

also I do think the number of flags in the circle is the total count of flags, not messages

(i can verify this since i can also see a list of who flagged the message)

N3buchadnezzar

is there a colloquial term for ` " ' surrounding some expression?

caird coinheringaahing

Does marking a flag as valid "reflag" it?

hyper-neutrino

wdym by reflag

Unrelated String

@N3buchadnezzar ...quotes? quoted?

like, if someone marks as valid i believe it is equivalent to just flagging the message directly

not sure

nested quotes?

Q: Blinking Lighthouses

Lighthouses on an island have blink codes that let ships know which lighthouse they are seeing. Codes are a list of strings of any combination of the letters S and/or L. Here is a Python example of codes for 4 lighthouses: ['SLS', 'SLL', 'SSS', LSL] where: S = short ON (1 sec) L = long ON (3 sec)...

caird coinheringaahing

> No import statements.

The shortest code (length in characters, whitespace excluded) wins (code-golf).

IIRC this was in the Sandbox as well :/

user

It was, and I even pointed out a (non-existent) issue in it without seeing that part :(

caird coinheringaahing

6:36 PM

It sucks when a new user posts in the Sandbox, it goes relatively unnoticed for a while and then they post it with noticed issues :(

John Dvorak

should there be a bump bot for sandbox challenges?

hyper-neutrino

i am considering working on a triage bot for the guild of reviewers to keep track of sandbox posts and ask for feedback based on likelihood that it'll actually be posted and such

OSP is nice but if the post gets zero activity it won't be noticed I think (except for the 1w mark? idk exactly how it works)

caird coinheringaahing

It posts any post that hasn't had any activity (edits, being posted) for a week

So something that's never been edited will be caught by OSP once, a week after it was posted

hyper-neutrino

ah okay

Redwolf Programs

@hyper-neutrino I was planning on making one but other stuff came up

caird coinheringaahing

6:46 PM

@JohnDvorak It might be worth creating a bot to bump inactive, low-voted Sandbox posts if the Sandbox goes however long without activity

user

The OP's modified their question, should we retract the close votes?

caird coinheringaahing

For example, if there's no activity for 12 hours, it finds a couple of "abandoned" proposals and makes an invisible edit to them

user

How do you make invisible edits?

caird coinheringaahing

Add a <p> element to the end

Unrelated String

@user we probably want the input format to be a bit looser still, and the body itself could use some help formatting while we're at it

caird coinheringaahing

@user I think it still needs improving tbh

user

@cairdcoinheringaahing Ooh, smart

@Catija Are you planning on adding an answer/edit beyond the status-completed tag, or should we just go ahead and add that?

Redwolf Programs

It's so frustrating seeing a post by a user who did everything right (used the sandbox, waited a while, etc.) and is willing to make changes and improve their question, that still ends up requiring lots of work because there wasn't enough feedback :/

user

:(

Redwolf Programs

I'll definitely put the Guild bot higher on my to-do list, this sort of thing shouldn't happen

@NewPosts That's something I didn't consider (or know about) when I first asked the CMM: There are upwards of 250 challenges about averages, by a conservative estimate.

user

It's nearly 7:30 here, which timezone do you mean?

Neil

huh, well, it is there in the docs; regex engines stop applying * when the term becomes zero-width, but whenever you get a zero-length match in a /g loop, the engine tries to make a non-zero-length match at that point first before trying to match later on in the string

compare the .NET engine which always starts searching from the next character if there was a zero-length match

I think the JS engine does the same
