I have 17 days to double how many sit ups I can do, from 20 to 42

But I think I might actually pass my Air Force physical fitness assessment the first time around

I get 55 out of 60 points for running (just gotta imagine the bakde potatto), and 12 or so out of 20 for push ups, so as long as I'm a few sit ups past the minimum of 39, I'll hit 75 points and pass

Then from there I have to go from 36 push ups and 42 sit ups to like 50-60 of each in a minute, and get my 1.5 mile run time down to under 10m

But I have a year or so for that

It was always so embarrassing in grade school that I barely had the core strength to do it even if someone was holding my feet down but even now that I've lost like 40 pounds since then and gained some core strength my legs just go flying instead :P

emanresu A

Yeah that's why I thought of it

(for context: I decided to change my pi ascii art challenge, which I still haven't got around to posting, to just require a distinct ASCII character for each size and limit sizes to 15)

and then realised mapping integers to distinct ASCII chars could be quite interesting in praclangs

For only 15 values there are on occasion hex builtins :P

Approximate π with ASCII art (related) One way to approximate π is to draw a 2x2 square with a quarter-circle in it. The area of the quarter-circle is π, and we can approximate this area by filling it with squares. To start, we divide the square into four squares, and colour in the only one that'...

@emanresuA Trilangle, 17: <a"#z">-z<\,o(/.@

att

wait can a character be printed more than once

Bbrk24

The a" and z" near the beginning are the end and start points respectively, so this is very easy to change which characters are printed

this is really just

start = 'z'
end = 'a'
while start > end:
  print(start)
  start--

@Bbrk24 Actually you can make it 16 by moving the @ to the left: <a"#z">-z<\,o(/@

So for example, replacing the z and a with } and ASCII control character \x1F respectively gives you a program to output all of printable ASCII in reverse order

I have a really cursed function in Python:

lambda x: (type(lambda: 'function'))(compile('print()', 'nowhere', 'exec'), {}, '', tuple(range(x)), ())

This function, when given a value, will output a function.

If you call the output function with no arguments, it works fine.

However, if you call it with arguments, it throws an error.

Which says it is possible to pass a negative number of arguments.

Anywhere from -x to 0.

Okay yeah that talk sucked

I'm not sure if Sundar was cynically selling something he knows is unviable to boost his company's stock price, or genuinely is disconnected enough from criticism and practicality to believe what he's saying (probably a mix of both), but it was sobering

He even answered a question I asked about why he thought this was wasn't just going to end in another AI winter, and he derailed almost immediately after giving the concerningly answer of "so far more computing power has made it better and maybe we'll hit a ceiling and maybe we won't"

So I've been working on an RPG system. I settled on 15 different character backgrounds, each of which gives you expertise in three skills, out of a total of 15 skills in the game. Then I wanted to make sure the backgrounds had as little overlap as possible.

I decided to model the problem with a bipartite graph: backgrounds on one side, skills on the other, and an edge means "this background gives you expertise in this skill." There are 15 nodes in each part of the graph, and every node has exactly 3 edges (i.e. it is 3-regular).

First, I wanted to make sure there were no two backgrounds that had more than one skill in common. That wasn't hard, and it turned out to be equivalent to making sure the graph has no 4-cycles. So then I wondered if I could also find a graph with no 6-cycles. That would mean that for any group of three backgrounds, there is no group of three skills such that each of the three backgrounds has two out of the three skills.

I was going to ask in TNB, but I did some Wikipedia research first, and lo and behold found this:

Tutte–Coxeter graph

In the mathematical field of graph theory, the Tutte–Coxeter graph or Tutte eight-cage or Cremona–Richmond graph is a 3-regular graph with 30 vertices and 45 edges. As the unique smallest cubic graph of girth 8, it is a cage and a Moore graph. It is bipartite, and can be constructed as the Levi graph of the generalized quadrangle W2 (known as the Cremona–Richmond configuration). The graph is named after William Thomas Tutte and H. S. M. Coxeter; it was discovered by Tutte (1947) but its connection to geometric configurations was investigated by both authors in a pair of jointly published papers...

It is the smallest 3-regular graph that does not have any cycles whose length is less than 8. It just so happens to be bipartite and have 15 nodes in each part. What a coincidence! Unfortunately, because it's unique, I don't think it gives me enough wiggle room to assign skills to the backgrounds that fit them best, so I'll probably use a different graph and put up with some 6-cycles. But it was neat to find a mathematical object that so perfectly fit what I was trying to do.

Ginger

that is neat indeed
