woops thanks @Dennis

@Mendeleev me >_>

@Mendeleev If you accept an answer on one of your challenges, you can get exactly 2k rep :D

Mendeleev

Thanks Riker

@HyperNeutrino :))))

Riker

@Mendeleev hm, your pic 404s on the chat profile for me

but it's fine in chat

nvm, that's my internet

user165474

@Mendeleev Yeah after I clicked it it was still UpWat but it changed to Mendeleev after I went to your parent SE account from your chat account

11 has nothing to do with caching at all, profiles get live-updated.

Mendeleev

@HyperNeutrino ah, OK

Riker

@Mendeleev congrats

Erik the Outgolfer

Exactly 2k rep.

Riker

is that edit privs?

Mendeleev

Huh?

No, I could already edit

19:02

I used to have 404 rep then someone upvoted one of my answers :(

Riker

oh, deleting question

Erik the Outgolfer

No that's delete privs.

Mendeleev

This is mod tools

Riker

yeah, some of them

betseg

@Mendeleev thats a lot of tabs

Mendeleev

19:02

@betseg It's not that many

Erik the Outgolfer

@betseg Then you'll faint with mine o_O

betseg

@Mendeleev ...wow

@EriktheOutgolfer plz dont share a screenshot then

Mendeleev

ffs I had 105 yesterday

betseg

.........wow

Mendeleev

Yes, I have a tab problem

betseg

19:03

i usually have somewhere between 1 and 4 tabs

Jan Dvorak

8

Zwei

4 spaces w/ haskell and python 2 spaces when using lisp

never tabs

AdmBorkBork

Tabs? I open every page in a new window. :p

Mendeleev

@betseg how do you survive

Zwei

oh oops misunderstood conversation

betseg

19:05

lol

Zwei

1-2 normally, 8+ when programming

Jan Dvorak

don't worry, we can discuss these tabs, too

Mendeleev

I usually have 3 chatrooms, 2 mailboxes, discord, my dev applications, and then a bunch of either reddit threads or programming resources

Jan Dvorak

when we're done with tabs vs spaces we can switch to politics or religion

AdmBorkBork

Or the pronunciation of "GIF"

Jan Dvorak

19:06

jif

Zwei

politics: I think we can all agree that S. J. res 34 was a horrible bill that should never have passed

Mendeleev

Tabs vs. spaces poll

Conor O'Brien

seriously people

Zwei

I pronounce it with the G as in graphics

betseg

politics: turkey probably will become a dictatorship this sunday

Gif is clearly pronounced gif, not gif.

@Zwei jraphics

betseg

@Mendeleev i too enjoy the JFEG image format

Mendeleev

@betseg GIFPEG

Zwei

what are smart tabs

Mendeleev

@Zwei No idea, but those are the three settings in my editor

Conor O'Brien

19:09

Gif, n. A word designed to cause arguments

Zwei

I'm a vim person trying to switch to spacemacs so I don't understand atom stuff

betseg

@Mendeleev what i mean is, if you want the abbreviation to match with the words, pronounce it as JFEG, not JPEG

Mendeleev

@ConorO'Brien GIF: Graphics Interchange format.

Q: Is this answer valid?

I recently posted an answer on the Hello, World question and after posting, discovered this answer claiming to do it in 18 bytes in brainfuck. I read through it and thought that it was completely wrong and so notified the OP in the comments. We then had a bit of an argument about whether this is...

Mendeleev

@Zwei This is IntelliJ IDEA. I usually use vim though. Why switch from it?

Zwei

19:10

mostly because I'm looking into using lisp, and spacemacs is the closest thing to vim that works with slime

Mendeleev

ah

@Mendeleev Is that a null byte? I can't tell

Mendeleev

@ETHproductions It is U+202e

ETHproductions

Oh...

It's impossible to tell just from looking at the message

@HyperNeutrino ok

user165474

I mess around with weird things in the Sandbox all the time. As long as you don't flag things that don't need to be flagged, pretty much anything is fine

ETHproductions

Hmm, the chat isn't automatically scrolling for me when new messages are posted...

How does one use a custom code page for an esolang?

AdmBorkBork

Since the interpreter just receives a byte stream, the code page is just a way of making that byte stream easier to read/understand.

You're just saying % means 0x6A (or whatever).

For convenience, it's probably a good idea to re-use existing symbols, so you can write in (say) UTF-8 and have your editor spit out the proper byte-stream.

Wheat Wizard

Ok so you just make a new editor for the language?

AdmBorkBork

Sure, or a pre-interpreter that understands UTF-8 on input and byte-stream on output.

Wheat Wizard

Ok cool

AdmBorkBork

Or, like Jelly, take the input stream as either its custom code page or UTF

That's why you can program in Jelly in the Unicode code points, but get the 1:1 byte count from the code page.

Because, if you take the time to translate that UTF-8 file into the corresponding Jelly code page, you'll get "the same program."

(implementation is left as an exercise for the reader)

Q: Optimize sorting, using "Sub-vector reversals"

This is a code-challenge where the objective is to sort a vector into ascending order using the fewest reversals. Your algorithm can only sort the vector using "sub-vector reversals"1, but it can use other operations for arithmetic operations, loops, checking if it's sorted etc. The number of sub...

@Riker What kind of unsaved work? A lot of the time you can safely close almost everything and the tab with the unsaved work will pop up an alert with "are you sure you want to navigate away?"

Riker

... yes :D

Wheat Wizard

@AdmBorkBork Might it be easier if I want to use an existing codepage like IBM 437. not that its terribly hard right now.

Pavel

@Pavel here it is

AdmBorkBork

@WheatWizard Yeah, that's true. Or one of the APL ones, but those are EBCDIC, which should DIAF.

@Pavel You can let the bot do its job.

Pavel

@mınxomaτ Out loud I pronounce gif like in "graphics" but in my head I pronounce it like "jelly"

@AdmBorkBork The bot is slow, and I didn't onebox it.

I've noticed something. I tend to upvote every non-broken answer I get to any of my puzzles, and I'm wondering if that's considered good practice?

@Pavel They're your votes; you can distribute them how you want. Upvoting every answer in a short period of time may trigger a serial voting detection algorithm, but I don't think there's anything inherently wrong with it.

every time. Dennis stop being so mean >_>

@Pavel They're two different algorithms. Dennis' is a recursive function (which is usually shorter in Python) and ovs' is an iterative solution.

@AdmBorkBork Afaik serial voting only applies to casting multiple votes on posts from a single author.

Helka Homba

What's a good way to keep a bunch of unique strings (like a list of vocabulary words) in an easy to edit document? A single column spreadsheet kinda works but a lot of space is wasted and duplicate checking is not automatic.

Dennis

@Pavel Is it mean to post answers now?

@Riker I haven't been on cuz school and spring break

Dennis

@Pavel Unless very badly golfed, I tend to be a bit more lenient with answers to my own challenges as well.

AdmBorkBork

21:41

@Dennis Ah, I had thought it was either from or to a single user.

@HelkaHomba Maybe just a simple text document and run a quick de-dupe script after major changes?

GC a.txt|select -u >a.txt

Should work with PowerShell.

Helka Homba

@AdmBorkBork I'd also like to alphabetize words, and some strings may contain spaces (like "avant garde" as a vocab term).

Pavel

@Dennis it was a joke

What's the algorithmic complexity of deduping an arbitrary list? You can do nlogn by sorting it first but I feel like there should be a better way.
