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

12:07 AM

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?

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!

okay, I did it

yup ~_~

right?

yea, sure, whatever

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

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

how would you do it in Python?

lyxal

same way

just with the actual functions

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

@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).

3:23 PM

@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

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

Seggan

5:25 PM

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

6:27 PM

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

thejonymyster

7:01 PM

@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
