I have been spending my $PARTOFDAY$ trying to get a LEGO MINDSTORMS EV3 Brick running Linux to understand how to use DNS over Bluetooth NAP

@hyper-neutrino They accidentally yeeted stuff into the DBA.SE chat

hyper-neutrino

oh

yeah I would've noticed if I checked the mod flag history lol

Ginger

as I type it's installing dkms so I can build a kernel module for a WiFi adapter

emanresu A

@Ginger Okay wow that's cool

Ginger

00:07

isn't it?

slow as all hell but still super cool

emanresu A

I'm surprised that its 5MB of storage can store linux

Ginger

It can't

You have to use an SD card

emanresu A

Ohh

Ginger

for some unknowable but fortuitous reason the EV3 firmware checks the SD card for an OS before launching the built-in one

so it was just a matter of flashing an SD card

and in true Linux fashion it comes with "batteries included but not really" software

for some reason I had to manually add 8.8.8.8 to its DNS server list

because the built-in interface for doing so locks up when you click Add

oh boy 53% done

@user does lambda a,b:[b,*a][-1] work?

Ooh, that's clever

Welcome to the 21st Biweekly Mini Golf. During this event, we'll post some CMCs (Chat Mini Challenges) for you all to solve. A new one will be added every 5 to 10 minutes. Feel free to keep suggesting drafts during the event. If you have any questions, don't be afraid to ask. Good luck!

but I feel motivated enough to do it tonight with some AI generated CMCs (which are hence referred to as AICMCs)

@Nobody people just haven't done it lately, that's all

AICMC: Given n, print out all numbers smaller than or equal to one million that end with the same digits as n

@lyxal oh ok

@lyxal how

lyxal

@Nobody I use GPT-3's Codex to generate CMCs based on previous CMCs I've given it

@lyxal oh ok

lyxal

AICMC: Print the first N prime numbers (n is prompted input)

Seriously @Nobody please stop spamming pings

ok

# **AICMC** Number 1: Given a list of numbers, find the number that appears the most often.

hello bot!

it's time to run an... experiment.

not in here

I'm not a dumdum

I'm going to write some code for GingerBot that searches through TNB and finds old CMCs to post

12:57

wait no i messed up LOLLL

It never happened

Jo King

SE is down again?

Ginger

okay, I did it

thejonymyster

yup ~_~

Ginger

GingerBot now has the ability to get CMCs from this room's history and post them

thejonymyster

post the best cmcs evar

Ginger

13:07

Request permission from ROs to run bot in TNB for the duration of BMG, posting CMCs at 15-minute intervals?

Jo King

as long as it doesn't overthrow humanity

Ginger

It won't

right?

GingerBot

yea, sure, whatever

lyxal

it can have 22 minutes of fun

Ginger

excellent.

powering up now...

thejonymyster

13:08

15 minute intervals... 22 minutes... that adds up to like.... pi cmcs if my math is correct :P

for this BMG, probably

for proper dry runs, no

what should I change it to?

ighto I think that's enough CMC posting @GingerBot

at least for this test run

hyper-neutrino

wait is the bot automatically posting

Ginger

okie dokie

bot offline

graffe

@lyxal very nicely done

Ginger

that was an interesting experiment but I think more polishing is needed

graffe

13:32

how would you do it in Python?

lyxal

same way

just with the actual functions

graffe

is there a closed form that might be shorter in python?

thejonymyster

. = dot operator, decimal point
.. = concatenation
... = spread, other stuff ellipsis does
.... = ?

hyper-neutrino

@Ginger Please experiment with bots in the Sandbox or its own room (or another room like Edge of Propinquity if it's permitted there) rather than here, and also bots are actually banned here without explicit approval like NSP/NMP, and OSP have (and VyxalBot during the Vyxal LYAL).

Should the BMG be unpinned now that it's over?

hyper-neutrino

I mean yeah it's just because I misinterpreted Ginger's message and also backread too fast and missed Jo King's and your message lol. So yeah sorry about that. I do like the idea though so having it for BMGs would actually be really cool.

PyGamer0

in Wellscripted, 14 mins ago, by PyGamer0

basic grammar i have in mind

hyper-neutrino

and yeah I'll unpin

lyxal

too bad, I did it myself :p

PyGamer0

lol :p

hyper-neutrino

13:46

(or someone else already did) it can stay starred though in case anyone wants to look through the BMG and the CMCs starting from it

lyxal

I just wasn't sure when to do it, that's all

thejonymyster

@PyGamer0 expression_list?

PyGamer0

@thejonymyster lets just say its expression_list: expression ";" expression_list

lyxal

@hyper-neutrino happens to the best of us

thejonymyster

@PyGamer0 ok thats what i guessed but i dont like guessing :P

guessing is the gateway drug to being wrong

lyxal

13:48

@hyper-neutrino funny thing is that I had to move some bot stuff to the edge anyway :p

also vyxal bot broke lol

15:23

@PyGamer0 Not especially

I definitely think == for comparisons is a lost cause, having it be = instead is too confusing for anyone who's used to normal languages

user

It's also just not a hill worth dying on

If = wasn't used for assignment I'd think it was for unification

pxeger

also, Go uses := only for combined declaration and assignment

it still uses = for (re)assignment

user

I like <- but it's an extra character, which is annoying

CMC: find two lossless compression systems A and B, and a piece of data X which can be compressed in both. You want to have the greatest ratio (length of X when compressed by A) ÷ (length of X when compressed by B)

Seggan

17:25

could be solved using image compression formats

pxeger

the best strategy could be to compress some data using a format which is designed for it, and one which is definitely not

e.g. encoding text with gzip, and then with png

user

18:27

@thejonymyster I'd like := for declaring variables and <- for reassignment

thejonymyster

19:01

@user whats the difference between declaring and reassignment :think:

(i forget if that pings)

mathcat

Declaring is when you first set a variable to something, and reassignment is just when you reassign the variable to a new value.

thejonymyster

declaring is reassigning a variable from undefined to a different value

mathcat

right

altough no

hyper-neutrino

that's unclear because in javascript you can assign a variable to undefined
