Fun fact: if Jon Skeet only got reputation by being awarded +1 for every answer he posted, and no more, he'd be 32nd in the CGCC all time rep leagues

At +2 per answer, he'd be 10th, +3 he'd be 6th and at +4, only Arnauld, Martin and Dennis would beat him :P

@Deadcode Yeah, usually spreading out edits is a good idea because there's constant activity anyway, so a periodic edit over a week isn't annoying, but pushing down too many active posts might be more troublesome. No worries though, just so you know for the future :)

I wish there were a way to edit something quietly. Not sure if that would be for better or for worse.

ChartZ Belatedly

Oh man, I wish that existed so often

HyperNeutrino

Also that many edits made Community autoflag you for vandalism lmao

ChartZ Belatedly

Or even the option to choose for you edit to not bump, maybe if you reach a certain rep level. The number of times I've wanted to remove a tag used in like 2 old questions but haven't because it'd bump it ಠ_ಠ

CGCC's been busy over on Mother Meta today :P

HyperNeutrino

yeah, it is quite bothersome to not be able to just fix something quickly without bringing some like 18 year old garbage answer of mine onto the front page :P

ChartZ Belatedly

Maybe this'll finally convince the CMs to actually have a look at our other unfixed bugs :P

@HyperNeutrino I know you're exaggerating, but I'll be very impressed if there comes a point where you can bring up some 18 year old post of yours :P

> Member for 3 years, 10 months

That doesn't seem right, is that since your account deletion?

HyperNeutrino

1:10 AM

yes

ChartZ Belatedly

Thought so :P No way I've been around longer than you :P

HyperNeutrino

i have account activity from before then since apparently I'm able to have activity on my account from before this account existed, which I guess is fair enough :P

ChartZ Belatedly

Your first (undeleted) answer was in 2015, so you've clearly been around for longer than 4 years :P

Unless the apocalyptic 2020 I remember was just a dream and we're actually in 2019? Please?

@HyperNeutrino Mods can place an account in permanent "stasis" right? Prevent all changes to their account :P

(I don't think you can do that tbh, that'd be pretty OP, even for a mod)

HyperNeutrino

No, I don't think I can.

I don't think suspending you would even stop you from reaching the badge, but I'm not quite sure.

ChartZ Belatedly

Nuking my account would, but that's it I think

HyperNeutrino

yeah

the funniest thing about my account deletion is that it happened on my 97th consecutive login (I didn't have Fanatic at the time)

ChartZ Belatedly

Anyone who knows 05AB1E, is this answer valid? I don't know enough about Elixir and 05AB1E to know if it uses floating point arithmetic or not

@HyperNeutrino rip :(

HyperNeutrino

okay it wasn't that funny at the time :P but i have it now so

/shrug/

ChartZ Belatedly

1:23 AM

@ChartZBelatedly Looks like it uses floats

HyperNeutrino

can confirm reciprocal just does 1/to_number(x) so it's inexact

also by testing a large enough number

ChartZ Belatedly

Fun fact: in addition to handling infix, Jelly also handles postfix notation :P

HyperNeutrino

unfortunately no prefix :(

ChartZ Belatedly

Or anyfix

Bubbler

1:42 AM

@ChartZBelatedly Except that the argument that appears on the right is actually the left arg

ChartZ Belatedly

1:58 AM

@Bubbler Ssshh! :P

As long as you stick to commutative dyads, no one can tell the difference :P

Lyxal

@ChartZBelatedly that could make for a good JHT exercise

explain why it works

rak1507

yeah, I haven't got a clue

Lyxal

Bubbler gave the answer

ChartZ Belatedly

2:20 AM

@rak1507 The first 1 sets the argument for the rest of the program, so the remaining 2 + uses the 1 as the missing argument

Try replacing the + with , in the two linked examples

HyperNeutrino

2:35 AM

long story short, the 1 is a nilad at the start of a niladic chain so it becomes the lone argument and the rest of the chain is evaluated monadically

in a monadic chain, a nilad-dyad pair like 2 + combines to a monad meaning x => 2 + x, which takes the lone argument 1 and replaces it with 2 + 1 which is 3

then since it's the end of the chain, that's the implicit return

at least that's from my (probably rusty) understanding of jelly chaining rules from my several hours of studying it years ago :P

Bubbler

It's actually very clever design because it eliminates one reason to use Commute in APL and J (where it costs one byte for nothing but syntactic reasons)

ChartZ Belatedly

2:54 AM

@HyperNeutrino That's how I would've explained it if I weren't on my phone :P

ChartZ Belatedly

3:05 AM

@Bubbler Is Commute the APL/J name for Jelly's ` (treat the previous dyad as a monad by using the same value for both arguments)?

Quality backtick escaping there :/

HyperNeutrino

i'm guessing it's @, but idk lol

Razetime

` and @ are under the same symbol in APL

ChartZ Belatedly

CMQ: How often do you look at users CGCC profiles? I typically check out around 1 to 3 different profiles a day (mainly new users tbh)

Razetime

⍨

@ChartZBelatedly any day I'm bored I look at someone's profile and answer a bunch of their top questions

then i hop to another profile and the cycle continues

Bubbler

@ChartZBelatedly HN is right, it's @ (take a dyad and flip its two sides)

@ChartZBelatedly I rarely look at others' profiles. I look at mine x times every day, where 1 < x < ∞

I'm so narcissistic

ChartZ Belatedly

@Bubbler Oh yeah, narcissism on SE's classic :P

I have a tab open with my profile on my computer pretty much all the time

It's why I keep spouting random facts about rep and badges :P

Bubbler

Relatable

ChartZ Belatedly

How else will I know I'm 85% of the way towards Socratic???

Redwolf Programs

I just bookmarked my profile and I use that to get to CGCC

It's also useful for getting Fanatic which is why I chose my profile

I could probably change it now but ¯\(._.)/¯

ChartZ Belatedly

Amateur, not using the app to get Fanatic :P

Bubbler

3:20 AM

Socratic is my "next tracked badge"

ChartZ Belatedly

Same

Redwolf Programs

Mine's Strunk & White

ChartZ Belatedly

CMQ: How close are you to your next tracked badge?

Bubbler

Me for Socratic? It's at 94

Redwolf Programs

I'm at 41 for Socratic, I tend to post all my good ideas at once

ChartZ Belatedly

3:21 AM

@Bubbler Guess I need to post 9 challenges before you to match you :P

Bubbler

And then there was a CMP when I got my first gold:

Jan 19 '20 at 23:48, by Bubbler

CMP: How many of you have "Fanatic" (visit the site each day for 100 consecutive days) as your first gold badge?

Wow, that's over a year old

Redwolf Programs

I wish you could install custom keyboards on Chrome OS

I get why you can't, but it'd still be a useful advanced feature

ChartZ Belatedly

@Bubbler Guilty :P

I've been here 4 years, and I got half my gold badges within the last 6 months

HyperNeutrino

@Bubbler yep, though I got my gold code-golf tag badge only 5 days later

granted, I would've gotten fanatic 97 days earlier under normal circumstances

my most recent gold badge was two and a half years ago, electorate lol

ChartZ Belatedly

@HyperNeutrino Just step down as mod, you'll get Sheriff :P

Razetime

3:36 AM

step down right before next election

Redwolf Programs

No way, I messed with my parser and nothing caught on fire or resulted in mass tragedy

HyperNeutrino

bruh

ok just to confirm that i am not stupid you are joking, right? sheriff is awarded after serving mod for a year which i have not yet?

ChartZ Belatedly

@HyperNeutrino Wait, is it not September?

I think that's when the election was

HyperNeutrino

@ChartZBelatedly no, it's like March 380th, 2020 or something like that

yeah the election was sept 2020

specifically, my account gained the diamond on september 29th, 2020

ChartZ Belatedly

Pretty sure it's still 1990 :P

@HyperNeutrino NGL, I legit thought you'd been a mod for a good minute

HyperNeutrino

3:45 AM

Time is all an illusion now, between March 2020 and now I legit have no concept of the passage of time anymore lol

@ChartZBelatedly approximately equal to the number of pending flags

I updated Chat Monospace Fix, to fix a bug with the formatting when editing. Turns out I also forgot to do the rename last time, so you might have to uninstall the old one since it's been renamed to the correct one now.

(The bug was that the background was still light, so the text was almost invisible in the preview. I made the highlight color dark on the editing screen now)

I doubt anything close to harmful increases in size will occur, although who knows :p

It'd be a lot less dangerous than a zip bomb anyway though, because your (or your anti-virus') first instinct isn't to zip a mysterious file
