So you either earn $10 or nothing, but the expected earnings are $5. It's the same with the bounty.

MD XF

Huh

I guess that makes more sense

Except it costs no rep to answer

Dennis

But it costs time.

MD XF

Ahh

Magic Octopus Urn

@Dennis I bet that you could've answered the question in the time of this conversation ;P.

Business Cat

Assuming there's an equal chance each answer would get the bounty, then each has a 20% chance of getting the rep. E = 0.2*100 + 0.8*0 = 20

Magic Octopus Urn

20:02

19 minutes? Maybe.

Plus now it's just a FGITW bounty, so there's no ifs ands or buts, the person who starts at it first is now most likely to win.

AdmBorkBork

@Dennis I don't wanna play, because the house always wins.

Dennis

That's because "the house" wouldn't let you pay $5. :P

MD XF

Wait so my question got tweeted but got <200 views and no answers :(((

HyperNeutrino

What I'm wondering is how many people actually check that Twitter feed.

Magic Octopus Urn

What's a twitter?

MD XF

20:05

@HyperNeutrino I do, when I'm seeing my questions posted on twitter :D

HyperNeutrino

lol

DJMcMayhem

@MagicOctopusUrn Something that twits

Magic Octopus Urn

@DJMcMayhem is... is it me?

Dennis

I like Twitter's suggestions on the left. I couldn't be less interested in any of them.

Magic Octopus Urn

Wait twit means: "tease or taunt (someone), especially in a good-humored way." Didn't know that.

I always thought it was like "idiot".

:39016031 Why did you delete it?

Socratic Phoenix

@MDXF you pinged me? (In language dev). D'ya need a thing?

Magic Octopus Urn

20:08

Large images in chat, feels like it should be used for a laugh and removed.

MD XF

@SocraticPhoenix Oh yeah, you'd asked a question and I answered a while ago so I pinged in case you didn't see it

Socratic Phoenix

Oh xD

HyperNeutrino

But what's the point in a permanent transcript if you're just going to delete things afterwards? Besides, an un-boxed link takes up just as much space as the notification that a message was removed.

MD XF

@HyperNeutrino There's a notification?

Magic Octopus Urn

That's the notification.

HyperNeutrino

20:10

Not a notification, but more so a chat-message-like thingy

MD XF

oh okay

@MagicOctopusUrn I've been wondering for quite a while why your name was "Magic Octopus Um"

Dennis

:39016099 And those don't show up in the transcript, making it utterly confusing if messages got removed.

MD XF

It's Urn ಠ_ಠ

Dennis

I like that I can still reply to (removed) messages.

HyperNeutrino

Is that a mod thing?

Magic Octopus Urn

I cannot do that.

HyperNeutrino

No reply link.

Magic Octopus Urn

You can click on the history of the (removed)

HyperNeutrino

oh hm.

Magic Octopus Urn

HyperNeutrino

@MagicOctopusUrn um... no history link for me either.

That only works if you're the OP or a mod.

MD XF

@HyperNeutrino Really? There is for me

Magic Octopus Urn

Hyper, it's only on your own removed messages.

Oh, OP, doi.

HyperNeutrino

I don't see the reply links on removed messages though.

HyperNeutrino

MD XF

Poke

The reply button is there but it just @tags the person

HyperNeutrino

I always click the dropdown on the left

MD XF

@Poke That's what the reply button always does

HyperNeutrino

@Poke yeah it's because there is no message to link to (I think)

Dennis

20:13

@HyperNeutrino That's not very golfy.

Poke

yeah but it usually links to the message

MD XF

@HyperNeutrino 0/10 waste of time

HyperNeutrino

@Dennis what, dropdown > reply?

MD XF

:39016180 test

Oh yeah it doesn't link it

HyperNeutrino

Actually, fun fact, I use caret reply. Even faster if you're not replying to messages that were posted a few days ago.

Socratic Phoenix

20:14

wow that didn't even show up as a ping @MDXF

Dennis

@HyperNeutrino Yep, two strokes instead of an ace.

MD XF

@SocraticPhoenix Weird!

Socratic Phoenix

It is!

MD XF

Oh hey you can also flag deleted messages... odd

HyperNeutrino

But I always keep my mouse near the left side of the screen (for whatever strange reason) so it takes more time to move it to the right.

Magic Octopus Urn

20:14

MD XF

heh

Socratic Phoenix

@MagicOctopusUrn accuracy?

MD XF

Hmm, I wonder what's a good anagram for MD XF

HyperNeutrino

@MDXF Well yeah, posting offensive stuff in chat isn't acceptable and if people could get away with it by deleting it before something could happen, that's bad. Moderators can still see what was posted even after it's been deleted.

@MDXF XD FM

MD XF

@Adám Would the Roman numerals be at face value, and the Hex digits be valued based on what column they're in?

Adám

@trichoplax Probably. But maybe FM should be 984?

And what to do about C and D?

trichoplax

And should a Hex digit to the left of a larger Roman numeral be subtracted from it?

Oh you meant that already...

What if FM is 744?

Adám

@trichoplax Right. There are definitely some things to think about.

trichoplax

Either way this could be interesting as "Find the shortest Roman-Hex representation of this integer"

Adám

@trichoplax Right, I thought of that, but first we need an unambiguous Romahex format.

trichoplax

20:50

I guess you need to decide how many consecutive digits can be added together. Can you have IIII for 4, or only a maximum of 3 in a row?

This might be a long spec...

Adám

Also needs a name. "sex" (from Latin "sexadecimal") pops to mind.

caird coinheringaahing

@Adám the clarification was much needed :P

trichoplax

Definitely clickbait. Might not attract just your target audience...

Adám

It really wasn't:

Hexadecimal

In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a, b, c, d, e, f) to represent values ten to fifteen. Hexadecimal numerals are widely used by computer system designers and programmers. As each hexadecimal digit represents four binary digits (bits), it allows a more human-friendly representation of binary-coded values. One hexadecimal digit represents a nibble (4 bits), which is half of...

@trichoplax Modern Roman numerals may only have a single subtracting char to the left of a bigger one, so how about saying C is Roman if to the immediate left of an M or to the on the right of a Roman M, D, C, optionally separated from them by a single X or I. D is only Roman if following an M, optionally separated by a single L, C, X, or I.

@Adám So CM is a Roman C, MC is a Roman C, MD is a Roman D (and it took me a moment to realise DM has no reason to be Roman...)

@trichoplax Right.

@cairdcoinheringaahing I appreciate the thought, but for whatever reason it's stupidly hard

I've been working on it for 30 minutes, and it's way too long and doesn't even work ;_;

trichoplax

@Adám Make it as richly horrific as possible - I'm sure you can find a volunteer to make a reference implementation...

Adám

@trichoplax Ah, yes. And D is Roman in 1D0, but Hex in 2D0.

trichoplax

21:26

@Adám I'd completely forgotten about the decimal side of hexadecimal. How do 1 and I differ?

@Adám Is that for an intuitive reason, by analogy with ID0?

Adám

@trichoplax That's easy. I is always Roman, so it subtracts from anything but 0 and 1 on its right, while 1 has its base-16 value and subtracts if the next char on the right is bigger than its own value.
