This program should flip n bytes from stdin, and write the result to stdout. Example: Before: Hello World After (n = 2, 2 bytes flipped): Hello wOrld

@mınxomaτ I'm curious whether those are supposed to be variations on greek letters or just... symbols

the upside-down trident thing confuses me, but not more than the horiz line with a vert line through the middle

I wonder what guest271314 did to get a 5 year ban...

@FrownyFrog how do you know O_o

@Riker most of them are capital english letters in case you couldn't tell :| one of them is lowercase a and most of the others are greek. in fact, the first paragraph tells you what each type of symbol means

80k rep banned for 5 years?

@primo 80k? O_o

primo

6:04 AM

it's 1 now, but the rep on SO alone was over 80k at the time of the ban

ASCII-only

yeah but... how can you tell

maybe he voted for trump, and the mods found out

questions / answers / comments all seem spotless, unless they've been scrubbed in a way that i'm too low rep to see

looking at chat, it seems there was a lot of accusing people of being white supremicists

and using very confusing terminology while being very pedantic about everyone elses

I'm not too surprised. Whenever I looked at his profile, he was suspended from at least two stacks, or banned from chat

Neil

well, I was going to guess something more benign e.g. his real age was discovered to be too low or he'd requested the suspension because he'd become addicted to SO

heyo

Anush

when solving edit distance using dynamic programming, you can think of it like solving a shortest path problem, right?

Jo King

yeah sure, each type of edit is a path, each state is a node

Anush

cool.. I was wondering how hard it would to find all the shortest paths

from the top left to bottom right

with a view to a ppcg challenge :)

finding one is sort of a textbook exercise

Jo King

It's weird, guest271314 says that race is a myth, followed up by

When people use the term "standard" and "non-standard" and "common", that is a signal to suspect them as being white supremacist practitioners

. That actually explains a lot about my interactions with him

Anush

10:11 AM

?

that's a surprising thing to write on ppcg :)

Jo King

nah, not on PPCG

but it's still weird for a chat on etymology

Anush

what about my question directly related to coding! :)

Jo King

sorry, it was related to an earlier discussion

i mean, finding all shortest paths isn't too much different from finding just the shortest

Anush

@JoKing oh ok.. so what do you about it as a ppcg challenge?

Jo King

if you have a limited amount of operations, it's just a breadth first search

Anush

10:14 AM

maybe even to draw them on an ascii version of the dynamic programming table?

Jo King

hmm, i dunno. It would depend on the format. Try posting a draft to the Sandbox, and see what responses you get

Anush

thanks.. I might not as I don't know how to make examples :)

we need a sandbox request for volunteers

where you pose questions and ask for volunteers for examples :)

wow, that dude is a nutter

user202729

11:14 AM

You're not supposed to talk about people's suspension...

@Anush Just backtrack to get all cases, although there can be exponentially many shortest paths.

Anush

@user202729 sounds good

@user202729 I guess if you are drawing them on an ascii representation of the dynamic programming table then you never have too many edges

user202729

Even if there's not a lot of edges there can still be many paths.

I am against migration of people... Each one goes in his or her how country if want adjust something... If you want ban me for this: Free

In his her own country in above phrase

primo

i'm currently an immigrant to my country of residence, and also to the country I resided in before this

there are legal channels for immigration, and I think these laws should be enforced

i disagree with a "you were born here, you die here" philosophy

RosLuP

I disagree above: In the country someone born in that country he or she has to die

primo

sometimes people disagree

¯\_(ツ)_/¯

RosLuP

The problem is that what globalization or export problem is not the right way of resolve problems... Yes possible I wrong on this (and I drunk something) but is my politics position

Problems has to be local not global

Anush

11:50 AM

@user202729 right but if you only have to draw the edges the output will not be too large

@JoKing Another example of the kinds of messages from this guy: "One example of another fraud is the "theory" of human skin pigmentation being result of "evolution"

Anush

possibly a troll?

some people just like to get attention by being as outrageous as possible

@Fatalize that was meant to be in reply to this comment

Fatalize

12:08 PM

@Anush He seems way too commited to a troll then :p

Anush

@Fatalize :)

maybe he should be committed

as in en.wikipedia.org/wiki/Involuntary_commitment

in case it didn't translate :)

ppcg has latex support now?

see for example codegolf.stackexchange.com/q/181885/4098

I thought the idea had been soundly rejected

Anush

@primo they came to a curious compromise about $s

@primo \$n\$ instead of $n$

by making it a little more annoying to type the math they can ensure fewer people do it :)

primo

hah, somehow i doubt that was the primary motivation

Veskah

@primo Shhh, otherwise they'll make it require even more dollar signs and escape characters

primo

aha, too many languages use $ as sigils, makes sense

Anush

@primo :)

@Veskah good point!

Perl and PHP would be unusable if $ was the delimiter

J. Sallé

@Mego That sentence suggests PHP is usable in the first place ಠ_ಠ

Anonymous

@J.Sallé It's usable in the same way that a knife embedded in your arm is usable

It is possible better not to eat cheese... Not eat cheese if don't know personal the sheep 🐑 produce it... Because dioxin can be in what sheep eat and concentrate in milk (nei grassi)

I dreamed of my grandmother telling me not to eat meat and even cheese , some time ago...

I don't know if this can be right out of Italy my nation ... Possible in us or australia cheese is ok
