LDQ: What format should I use for the library module databases?

I'm not sure JSON is the best idea for them q:

Seggan

im not planning to ultimately use json for rol either, json is just easy to read/debug

go with msgpack

Ginger

nah, msgpack is weird

Seggan

i love it

why do u think its weird

Ginger

lemme say that better: msgpack is cool, but this is not a good use-case for it

Seggan

why not

its compact

Use OISB iobin serialization format 1

Ginger

use what

Rydwolf Programs

A custom binary serialization format we developed for internal communication between the inside and outside of a sandbox :p

Ginger

who's this "we", kemosabe

Rydwolf Programs

Actually use serialization format 2 it's better

@Ginger Me and AviFS

Ginger

lol

CMP: should i implement a spring based physics engine from scratch or try to make on on top of box2d

Sandbox Posts

A: Sandbox for Proposed Challenges

True random (based on wind speed) code-golf Scientist want to create true random number generator. He already wrote a program which gives him a wind speed based on date and location on Earth and multiply this value to -1 pseudo randomly. Help him to generate a true random number in given range Y...

hyper-neutrino

did someone say spring based physics engine

Rydwolf Programs

Ooh I remember playing around with that

Seggan

not working

Ginger

jank go brr

Seggan

9:12 PM

nvm i had to add objects

hyper-neutrino

@Ginger yep

as it says at the bottom, built in 1:30 at 2 AM so :P

mathcat

@hyper-neutrino I used to code a lot of physics sims in p5 js

Seggan

so what do yall think of my q

mathcat

@mathcat Found it!

@Seggan This is 2D physics, right?

Seggan

yep

Ginger

9:22 PM

~~I should use CSV for the database~~

mathcat

I'm pretty sure the latter is easier, but physics engines are fun

Seggan

true, but this is for a "real" application, and i dont wanna waste time

mathcat

oh, then definitely the latter

don't reinvent the wheel!

Ginger

9:26 PM

suppose I were to disregard my own advice and make a custom file format for library databases...

*chuckles* delightfully devilish, Ginger!

Seggan

@Ginger it wouldnt be that hard tbh

its not like ure making a physics engine

Ginger

yeah I guess

oh my god I just had the best idea

I'm going to use 🐇📕 as the "magic bytes"

Rydwolf Programs

@hyper-neutrino The gravity's too powerful, it turned my softbody rectangle into a pancake lol

Seggan

@Ginger lol

whats the 📕 for

hrm monospace does not work with emoji

Ginger

@Seggan because it's a library file

Seggan

9:35 PM

hyper-neutrino

@RydwolfPrograms lmao

Ginger

9:52 PM

okay, I have a format now

Seggan

what is it

(also protobuf?)

1 hour later…

A: Best of CGCC 2023 - Now Accepting Nominations!

Rookie of the Year - Challenges Repost of 2022, 2021, 2020, 2019, 2018. For the best challenge written by someone who has not written a challenge prior to 2023. SEDE query (modified from 2022) Aira Thunberg nomination by Seggan Aira has done something extremely rare for a new user. As I write thi...

Thanks for this @Seggan

unfortunately, Aira my friend decided to quit the platform as I was sending her these questions (she is really happy) and she merged her account with mine.

I would still thank you for appreciating her as a woman and her being an angel in my life to help me cope with autism

Seggan

11:46 PM

@AitzazImtiaz the questions were yours?

Aitzaz Imtiaz

@Seggan they were mine, she was posting them for me

Seggan

Aitzaz Imtiaz

but still, she did have hunger for knowledge

we both wrote a diary of such challenges

Seggan

if you could somehow confirm that id change the nomination

Aitzaz Imtiaz

see the questions in my profile

those are exact same challenges

Seggan

11:48 PM

ah yes i see

Aitzaz Imtiaz

I don't want to be nominated personally but thanks for appreciating her, that makes me happy :)

I guess she used to say here that the questions do not belong to her

Seggan

@AitzazImtiaz you have no choice lol

Aitzaz Imtiaz

@Seggan sorry but I was really emotional for Aira tbh and thats why I just wanted to thank you

thank you so much :,)

you really are unaware of sacrifices she did to maintain my emotional well-being

well, I prefer Sophie Germain over her anyways :D

Unrelated String

@RydwolfPrograms i think for something especially functional the patterns that make those useful should be better done some other way, but in and of itself it's not a bad idea to have truthiness

though you also get cases where committing to one behavior might be confusing

or rather, you make choices that you don't necessarily want to make

Rydwolf Programs

IMO it just feels elegant to be able to leave off a == 0 or .is_empty() or .len() == 0 or whatever

Unrelated String

11:56 PM

like, you could make all optionals truthy if non-empty and falsy if empty
but you might also want optionals of truthy-able types to also be falsy if the value contained is falsy

though i think the first choice does win pretty hard there and you could also just not make a choice

come to think of it that's actually a pretty good opportunity to just have a function for contains-truthy

which could even generalize to other containers as kind of an any analogue

yeah honestly there probably aren't any real cases where you create any weird contradictions

Rydwolf Programs

There's certainly cases where multiple ways of defining truthiness make sense, but I think we're already kind of used to that from dynamically typed languages, so I think as long as it's consistent within the language and the alternative options are easily available it would be fine
