Q: Algorithm for generation of fill in the blank questions

Background I have created an application that queries the user for facts, then allows them to set parts of these facts as fill in the blanks. One of the key ideas is the user will be able to create multiple facts, e.g. George Washington was a president of the USA and Franklin D. Roosevelt was a p...

CMP: Is this Uiua answer valid without the function signature?

I'm leaning towards no, given that the code cannot be assigned to a name or pushed on the stack without the signature, which makes it a snippet

Q: Meta question: counting bytes

Compare? Do I need to return a < b? a <= b? sign(a-b)?

As a test is 36028797018963975 < 3.6028797018963976e+16 < 36028797018963977 good?

@l4m2 I was actually toying with the idea of having a question to implement custom total ordering on both doubles and ints, where -0.0<0<0.0 and positive ints compare less than their double values while negative ints compare greater

@AidenChow round(x) = ceil(x + 0.5)

sorry, I meant floor

ceil(x - 0.5) I guess, although that rounds 0.5 in the wrong direction

Bubbler

also ceil(x) = -floor(-x)

hyper-neutrino

oh right

so round(x) = -ceil(-(x+0.5)) I think

Actually this can be 64 bytes, x=>(g=(a,b)=>a<1||a*g(a-b,b))(parseInt(x),x.split('!').length-1)

Okay so the most simplest script in existence is:

print('Hello, world!')

Or at least that is what you WOULD think?

Probably.

See we can get simpler with that, so let's just ignore null programs now.

Programs that look like this:

And let's ignore comments.

The_AH

The simplest program is... drum roll please... exit().

See in exiting the Python interpreter just exits.

It doesn't have to do stuff to STDOUT, doesn't have to assign variables, nothing!

Seggan

0 is shorter and does nothing at all

exit actually does something

The_AH

But Python still has to parse the number.

Ginger

> Python compiler

The_AH

19:15

So it does do stuff!

Ginger

also, I'm pretty sure you're wrong

just a second

The_AH

Huh what quote?

I never said anything like that.

Ginger

you are indeed wrong

0 results in fewer bytecode instructions than exit():

>>> x = compile("exit()", "st", "eval")
>>> y = compile("0", "0", "eval")
>>> dis.disassemble(x)
  0           0 RESUME                   0

  1           2 PUSH_NULL
              4 LOAD_NAME                0 (exit)
              6 PRECALL                  0
             10 CALL                     0
             20 RETURN_VALUE
>>> dis.disassemble(y)
  0           0 RESUME                   0

  1           2 LOAD_CONST               0 (0)
              4 RETURN_VALUE

The_AH

However!

Theroretically a space should result in even lower bytes.

I can prove it.

Ginger

I thought we were excluding null programs

The_AH

19:21

A space is not a null program.

It is still one character.

Ginger

actually, it's an error

>>> z = compile(" ", "space", "eval")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "space", line 1

IndentationError: unexpected indent

The_AH

No don't edit it!

The first one was gold!

Double meanings!

Ginger

I didn't think that was star-worthy, so it's just as well

The_AH

"actually, it's an exception"

1. Surface - It means there has been an exception.

Ginger

yes, I get it

The_AH

19:23

2. Deep - It means we need to make an exception for space programs.

Ginger

it's not very funny

The_AH

But it's thoughtful!

or deep, for that matter

My personality type is 50% S and 50% N so just expect that.

in my estimation, personality quizzes are slightly below Rydwolf's gender quiz in terms of actual insight

19:27

My life is worthlessly reduced down to a number unable to capture all the reactions and experiences, memories and friendships, growths and downfalls, mistakes and ideas.

Ginger

and really only serve to sort people into unnecessary categories

The_AH

Categories that will further make our lives fleshed down into worthless letters stringed together by some psychopath who invented personality types one day to deceive the human race into fire and non-growth!

This is prove that our lives are now just vacuums for the greedy to feed off to enlarge their families and make a complex.

Then he realized that he had been flexed off by life.

okay what

so the bit size of the factors is n?

**CMC** for a bit size n, output the biggest gap between the sum of the bit sizes of the factors of an integer of bit size n and n
