Regarding my domain appraisal challenge, the best score I've gotten so far is 1.478, meaning that it's typically a factor of 4.38 off from the correct number.

Q: Domain Name Appraisal

Domain name trading is big business. One of the most useful tools for domain name trading is an automatic appraisal tool, so that you can easily estimate how much a given domain is worth. Unfortunately, many automatic appraisal services require a membership/subscription to use. In this challen...

PhiNotPi

@flawr I've seen this. I think it's cool that they defined everything mathematically, but personally I don't think the flag is very aesthetic. (Why are the triangles different shapes and why do the moon and sun not appear centered in the triangles?)

Q: Let's draw the flag of Nepal

Nepal’s flag (Wikipedia, Numberphile) looks very different from any other. It also has specific drawing instructions (included in the Wikipedia article). I want you guys to make a program which will draw the flag of Nepal. The user inputs the requested height of the flag (from 100 to 10000 pixel...

3:36 PM

@flawr I've looked at several national flag rankings, and it's one of those things that's really hard to do because everybody recognizes/knows the flags ahead of time. It's much easier to rank city/state flags that nobody recognizes (also because there's a really big difference between a bad city flag and a good city flag).

We're talking about the Nepal flag popcon right? Looking at the text of the challenge, it's not really much different than most popcons that have been posted. The only difference is that, by choosing a difficult thing to draw, the barrier-to-entry was high enough that it didn't attract any low-effort answers.

El'endia Starman

Wow. LaTeX matrices do not copy-paste well.

flawr

@El'endiaStarman They don't?

El'endia Starman

@flawr Try it.

flawr

Oh you mean the output, not the source code?

Well this is just dijkstra, is it?

El'endia Starman

@flawr Yep.

Not only did I get strange characters at the beginning (from the left "parenthesis"), and not only were the numbers not separated by anything, they went from top to bottom, left to right. The transpose of reading order.

flawr

3:56 PM

Hm, that would be interesting to implement functionally

@El'endiaStarman That's really strange, I would expect the non-transposed way, as it is when you write the code?

El'endia Starman

Yeah, it's really weird.

El'endia Starman

@LegionMammal978 Looks like you could easily generate still lifes of any length.

Hmm. Finding the ones that fit into the smallest bounding box could be interesting.

zʏᴀʙiɴ101

@LegionMammal978 Found a 22-cell still life with the same pattern:

x = 17, y = 9, rule = B45/S12
bo$o$bo$2bo$bo$o6b5obobo$bo4bo5bobobo$2bob2o$3bo!

El'endia Starman

Well, no, the longest still life in a given box would just snake back and forth from one side to the other.

Wait, actually, that would not be a still life. To VarLife!

PhiNotPi

Any straight line is a still-life in that rule

El'endia Starman

Yes, but for a given bounding box, a straight line will not maximally fill the space.

9-cell still life in a 5x5 bounding box. Can you do better?

aditsu

4:31 PM

@flawr wow, that's long (twss)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@quartata thanks at least

El'endia Starman

Just bested myself with a 10-cell still life, lol.

Hmm. Looks like this problem is essentially trivial. It comes down to how many straight lines you can fit in the box with two cells of padding between them. Bummer.

El'endia Starman

Plus, bad questions can be answered in a greater variety of ways, most of them guessing or correcting the OP.

Yep, range is defined only for integers.

What about numpy's range?

why would it work?

Geobits

I can't see a non-integer range function without a step size working very well.

Looks like numpy just assumes a step size of 1 when not provided.

Geobits

Does it really output 2. instead of 2.0?

Yep.

Eww

Were they ever advertised as anything else? :P To me the community ads are a chance for the community to select useful and meaningful things to advertise, as opposed to random junk. Sure, I wouldn't really want to promote a commercial service that costs money, but I don't see anything wrong with advertising a free resource

TIO is more affiliated with us than Geogebra with Math SE that's for sure

Rubberduck is basically CR's pet project

True. I guess I'd just rather see our ads go toward advertising ways to get help and learn about our myriad rules.
