Your task is to regulate traffic on a crossroads. There are 4 roads coming from north, east, south and west. The input is a string representing the upcoming traffic on each road. For example, NNNWS indicates there is a total of 5 cars: three at the north, one at the west and one at the south. Th...

@Mego Thanks. That trick with `Yu@\` is neat, too. ~~May I use it in my answer?~~ Oop, it doesn't save bytes. Never mind

I like how media inflates numbers. But how the hell do you get from 800,000 to 80 Million...

@Geobits Actually I think it's something unique to the automatic chinese translations. AFAIK they have another "thousand separator" system than english.

nvm it's linked from one of the articles

Yeah, they generally group every four digits AKAIK

@mınxomaτ The trouble is, by linking to that crazy article, we may have given them ad revenue

@ΛεγίωνΜάμμαλϠΟΗʹ There's also updates: 255.wf

So it might have been 80 myriad(?)

@TùxCräftîñg does main[Args] -> puts[Args]; work the way I think?

yes, it print the arguments

@Geobits Looking at the google results for "minxomat", that seems to be the case.

@mınxomaτ what was the time difference between the two scans? i wonder if some timezone woke up and turned their servers on

I know that some things occurred. I tracked the traffic changes before doing the second scan. Then the whole US govt "Fear" ""hack"" fiasco happened, too.

@mınxomaτ So it's been you all along, not the Russians, huh?

1:32 PM

Social engineering the russians is the art.

ΛεγίωνΜάμμαλϠΟΗʹ

...yup, definitely making sysadmins angry

See, I can't index the US servers directly (legally). But I can post a list of IPs and let someone else do the work. They publish the data, I can use it, and they feel "cool".

And some sysadmins fixed their stuff. I think that worked out pretty great.

@Quill No my probing tools were a bit more sophisticated.

@ConorO'Brien I meant that too. But, the post I linked says

The only exception to this rule is using a programming language (or a feature thereof) that was implemented after the challenge was posted.

Marking an answer as non-competing does not exempt it from the challenge rules. — Mego 20 secs ago

Anonymous

@ConorO'Brien Done (this is what you were looking for)

Erik already linked to that, but interpreted it differently.

Specifically, he's claiming that "The only exception to this rule is using a programming language (or a feature thereof) that was implemented after the challenge was posted." exempts the entire subpoint "Answers that produce correct results, but break a rule of the challenge, ignore parts of the spec or violate a loophole.".

Rather than the exception only applying to the "newer languages" rule.

You're reading too much into that wording. The "only exception" portion is specifically addressing this ruling -- answers must still comply with every other portion of the challenge. Here, the challenge explicitly requires ASCII source code, which Jelly does not have. — TimmyD 1 min ago

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Can people with the privilege to VTD just do that?

Do the downvotes not get the point across enough? Why does it need to be deleted atm?

I'd say at least give him time to understand why it's invalid, not just throw some comments at him and delete within minutes:

> If the answer is invalid without the poster's knowledge, it shouldn't be deleted without notifying the poster first and giving him some time to fix his mistake.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:14 PM

Hm, okay.

Though it's unlikely that can be fixed, Jelly pretty much inherently breaks the rules.

Most likely, yes.

umm

@TimmyD I'm trying to build up an ASCII file that Jelly can read, using the Jelly encoding (i.e. in ASCII representation, it will have unprintables). — Erik the Golfer 1 min ago

Hmm

I guess props for trying.

I'd be shocked if Jelly can do that task without getting into the >127 range, but, sure, give it a go.

Welcome, Opener of Doors

Question: If A has one or more close votes as dupe of B, and B gets closed as a dupe of A, do the A->B dupe votes disappear?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yes iirc

wait no

you can't close B as a dupe of A iirc, the system doesn't let you vote to close as dupe of a closed/pending question

Right but A isn't closed yet, just has some close votes.

I'm not sure the pending votes count.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yeah, I still think you can't close as dupe of a pending close question

@Geobits Yes, that's what I mean. It would seem silly to keep the A->B dupe votes if B gets closed as a dupe of A.

One of the devs I talked to in my interviews described Google as a "money hose". Essentially, they have such a grotesque amount of revenue constantly coming in that they can afford to throw money at projects that may or may not work out. The budget for projects is essentially limitless - as long as you can justify the need for funds, you'll almost certainly get them.

@betseg That's a hoax. It's clearly just Arizona :P

Another dev called Google "the biggest start-up in the world"

Well...

@Mego That sounds exactly like what I picture of Google from the outside. It's the only way I can explain the number of new products they start and trash.

I still can't figure out what they're doing with Messenger/Hangouts/Allo/Duo :/

Anonymous

Despite being one of the largest companies on the planet, it still has that start-up feel in its offices (of which there are about a hundred iirc).

@Mego looks at Hangouts, Messenger, Allo, Duo checks out

I still don't understand what's so great about Power8/9. I mean, you can already have absurd amounts of threads using ARMv8/9. And ARM servers are the cheapest around.

@Mego Are you sure you're allowed to be saying this? Sounds like you may find yourself turned into a hamster soon.

@Yodle 90% success rate. That's really good in some fields :P

It's weird cause it actually ran correctly, just crashed upon exiting somehow

@Poke Of course! It's public knowledge.

@Geobits Yes, but a lot of it was rewritten from someone else's solution previously. I just made it more maintainable and better. For instance, if his encountered an error, a message box would pop up with the text "Something happen." Needless to say, people didn't know what that meant.

Anonymous

Biggest lie on the internet: "I have read and agree to the terms and conditions"

@Yodle Ah yes. "exit code 3221226525" is much clearer to most users ;)

@Mego What about "I confirm that I'm at least 18 years of age"?

3:19 PM

Haha, that was a different problem :P

@Geobits Get it to only error 1 in 20 and that's good enough for statistics.

@Yodle Does this help at all?

Not everything uses 95% confidence intervals

True, but plenty do.

@Geobits I did come across that, but tbh I'm not worried so much about the exit code right now. Got some issues going on with execution that are more important to figure out.

If run on a 32-bit OS, the exit code will just be that mod 2**32

@Mego My OS is Android, and I'm sure Android apps can't produce error codes.

they can

Except the terminal part of it.

cuz linux kernel

error codes are the way application crashes are detected i think

You can certainly System.exit(code) on Android, but it's a bit flaky.

I did throw in some custom error codes into mine, but none that are that one.

It doesn't always clear the activity stack, for instance, so sometimes you just end up at the launch activity instead of the home screen like you'd expect.

I've got an idea I'm working on in the sandbox involving time zones/time conversion between countries

Oh god, time zones. Shoot me now.

3:41 PM

^ this

That's why I need some golfed code to help me convert :D

Just dealing with DST already has my mind in a pickle

That's because DST is just plain dumb.

I think I'm going to have DST ignored for this challenge, since it just overly complicates everything

Even if DST was adopted by the entire world so there weren't seasonal shifts between zones, it would still be dumb.

3:42 PM

@Yodle Are you also going to exclude timezones with a 30 minute offset?

Idunno, haven't gotten that far yet. bbl

G.G

"conversion between countries" - just keep in mind a lot of countries span more than one zone.

@Geobits Including the one you live in, @Yodle

hmm not quite what i wanted from the reply to post option

it'll work

DST is ending soon, though

so that's a thing

Can't wait to be back in the good ole EST

For a few months. It's odd that here at least, DST lasts longer than standard time :/

3:45 PM

That is odd...

Not even just a bit longer either. It's like eight months to four.

@Dennis Congrats on 100k! :)

Yay, @Dennis!

Good gravy, I wish @Yodle luck with the time zone challenge. I mean, There's an entire (lengthy) Wiki article about only Time in Indiana, let alone the gigantic mess that the rest of the world presents.

Jeez that looks way too complicated. We should just drop timezones completely and all use UTC
