So sometimes the dark mode extension I use inverts images, which can lead to some interesting results when you're trying to look at lecture slides

emanresu A

Hmm yes, normal human

Well at least we're covered

emanresu A

gamer.

lyxal

Thank you introduction to computing fundamentals

very cool

Unrelated String

i love how it has a picture of a vr headset but doesn't have a bullet point for vr

lyxal

lecture slides: *mentions gaming*
lecture slides: *refuses to elaborate further*

gosh f*cking dang it they inserted a human organ in my computer chip again

Unrelated String

how does it keep passing quality control

lyxal

that's the uninverted version

because as I said before, the dark mode extension I use fricks up the images in the lecture slides

The slide content?

• Brain-Computer Interfaces
• May soon be able to image
all the brain’s electrical

Unrelated String

soon™

lyxal

got another normal human picture for y'all

(for those wondering, this isn't a live lecture I'm reading the slides after the lecture)

Unrelated String

remind me to put ™ in the perhaps code page so i have an excuse to have a bookmarklet for it so i don't have to constantly copy paste it from somewhere

CMQ: Is a game controller really a pointing device?

Unrelated String

there's like

@lyxal motion controllers presumably are, most others not so much

it like that time someone trademarked the y with two dots above it for an 05AB1E program

i think it was y with two dots above

@AaroneousMiller what do you have to say about this?

Unrelated String

the magic number seven, plus or minus two™

it's a crime to cite miller's law without saying the name of the paper

then please arrest the people who wrote the slides

I dislike this course it's annoying

I don't really get how RAID or compression/decompression is enhancing performance

Unrelated String

it's probably a vague sense of performance that encompasses speed, memory, and whatever raid does i don't actually know what raid does

emanresu A

I guess it could if you're transmitting large amounts of data?

lyxal

00:34

they don't elaborate further on what RAID actually is

emanresu A

@UnrelatedString It stands for Redundant Array of Inexpensive Disks.

Bubbler

wtf

DialFrost

can someone check my challenges plws :(

lyxal

no way

no fricking way

they said the funny line

emanresu A

It's basically back up storage

Unrelated String

oh yeah that

Someone went overboard with the society theme

it's weird because some of the content looks like it's recent and up to date

and then there's just windows phone

emanresu A

lyxal: What are you two arguing about this time?
user: They’re always using common phrases incorrectly!
Radvylf: Cry me a table, user.

The amount of things I don't like about this picture are uncountable

and that's all the lecture slides read

thank frick

CMC: You can make it so one of PHP, C++, Java and jQuery never existed. Which do you choose?

lyxal

PHP

jQuery is too much of a meme to delete, I'm impartial towards C++ and I like Java

I'm gonna have to do cookie stuff :(

emanresu A

Take three cups of sugar, half a gallon of engine oil, two eggs and a power drill and microwave for 20 years.

Bubbler

01:42

@emanresuA I guess C++ and Java take some role in evolution of languages, so I guess I wouldn't have got things like Rust if any of those didn't exist. So I pick PHP

also jQuery is so easy to reach for when I need some cheap dom hacking

emanresu A

I guess yeah, it's kinda abused thouugh

Radvylf Programs

PHP is like someone heard the phrase "code is data", shrugged their shoulders, swallowed everything in their medicine cabinet, and started writing

Radvylf Programs

Reminds me of the colors.js incident not too far back

But a little less bizzare and conspiratorial

emanresu A

Yeah

lyxal

the fact that there's no tri-intersection is upsetting my OCD

Radvylf Programs

Everyone knows you can never have all three of those. What, you mean to tell me a site can be informative, look good, and do things?

lyxal

like I get logically there probably wouldn't be an overlap of all 3, but the diagram just looks wrong

@RadvylfPrograms the context is that each handles their own part of the website

emanresu A

02:19

@RadvylfPrograms Yeah, that's impossible. look at chat, for example

Radvylf Programs

More like it does one and sort of manages the other two

lyxal

for once this isn't a complaint about content - it's a complaint purely about the visuals

Radvylf Programs

Idk, I actually kinda like it

lyxal

hey guys I found an irl picture of @user

Radvylf Programs

oh god

emanresu A

02:23

lyxal

that implies I'm a goat

I'm goatn't

oh no oh frick user's evolved

emanresu A

Fine

Apparently user also has arrow arms

emanresu A

No, this is user:

They're assuming that user has a head smh

CMC: Get 11'd.

DialFrost

?

Bubbler

@DialFrost Simple ascii art challenges are very similar to each other by default. I have no problem with them (people seem to like solving simple challenges), but I don't like seeing similar challenges too often.

So I'd say: post one, wait for ~a week, and post another

Also in sandbox overflow, you say "and - for the top and bottom" but there's no - at the bottom in examples.

Unrelated String

@lyxal if php never existed we'd never have gotten this

Bubbler

@DialFrost And "Too easy" challenges are fine (as long as it's not a dupe). Actually I'm against making things harder for the sake of difficulty, because such a change often makes it just more tedious, not actually harder.

DialFrost

@Bubbler whoops thx ill fix it

@Bubbler oh so you think "spaceship gunner" is ok for now?

Bubbler

03:58

kinda yes

DialFrost

thx

PyGamer0

@pxeger wow thats cool

Any More Feedback?

pxeger

08:06

I now have more rep than Radvylf

emanresu A

Rep is confusing.

If you think about it, a good answer will maybe get +5 and a good question +20. I don't post that many answers or questions, how am I earning 2k a month?

lyxal

@pxeger good job very well done

@emanresuA could just be that you're universally liked

2

ophact

08:26

@emanresuA Me: +9 for trivial answer, +8 for answer made after extremely long thinking, +3 for answer that took lots of planning, +5 for answer that ports other answers

That extremely long thinking answer only got +8 because of a bounty put on the question. Before that, it was +4

emanresu A

Me: +37 for severe HTML abuse

ophact

I don't get the logic of voters on this site...

lyxal

I just upvote everything

Simple as that

ophact

You don't upvote everything; you don't have enough votes per day to do so

lyxal

Well everything I possibly can in a single day

There's a reason I'm third on the most votes leaderboard

ophact

08:32

@emanresuA Ask @Fatalize, the user behind the Stuck answer to Hello, World, which has no bytes but gained 511 upvotes.

Wait what happened? I just suddenly gained two upvotes out of nowhere.

lyxal

@ophact sometimes you just mysteriously get +20 out of nowhere

ophact

Was it you?

lyxal

Hmm I wonder

I wonder how I knew to reply to an earlier message about it

Unrelated String

what a mystery

ophact

I sure wasn't asking for upvotes... just criticizing the logic of voters

I would've preferred five less upvotes on the argwhere answer and five more on the division answer... but it doesn't work like that here.

Q: Convert between graph representations

What? Let's say I have this graph: 1 \ \ 2 3 \ / \ / 4 I can represent it in 2 ways: A list of connected vertices. [[1,3],[2,4],[3,4]] A boolean matrix which shows where edges are: c |1 2 3 4 --|------- 1 |0 0 1 0 2 |0 0 0 1 3 |1 0 0 1 4 |0 1 1 0 ----- or ----- ...

done

i formatted it slightly

emanresu A

Oh, one thing: can we output any two arbitrary values instead of 1 and 0?

PyGamer0

09:23

yeah

edited the question

10:12

@SegFaultPlus4 you upset the mods i think

@Adám is there a way to type λ in your kbd layout?

graffe

I have a text fie I want to split into files with 50 lines per file. Is there a golfed one-liner command line for that?

(the last file can have fewer than 50 lines of course)

PyGamer0

which lang?

graffe

@PyGamer0 anything that can be a command line one-liner in linux

in the old days you would do these things with perl one-liners I feel

Adám

@PyGamer0 No. But Windows+. then the Ω category (at the top), and the Ω sub-category (at the bottom) gives you λ as the last character on the second line.

graffe

but sadly no one does perl any more

PyGamer0

10:20

@Adám ooh thanks

emanresu A

10:36

blog.codinghorror.com/the-php-singularity

Hm, youtube's written in python

pxeger

@graffe ato.pxeger.com/…

not golfed but it works

you might also want to try pr, but it's probably less reliable and might choke on weirdly formatted input

graffe

@pxeger that's pretty cool!

pr?

oh is that zsh only?

@pxeger what would it be in bash?

PyGamer0

10:58

@graffe I was sure there was already a builtin for it, but couldn't remember what it was!

that's why I suggested pr

@pxeger I don't know pr at all

pxeger

pr is really designed for sending text files to simple printers

graffe

ah ok

pxeger

11:58

@graffe I think what I wrote should work in bash too

@pxeger break doesn't exist in bash

huh, I didn't know that

wrap the while; done in ( ), and then replace break with exit

I like IDLE because it's pure Python and comes preinstalled

those who love vi(m) are really happy

they get a double pleasure. First the pleasure of writing code and second the pleasure of using vi(m) :)

When you use greek letters for variable names.

looks neat ngl

ophact

Didn't know that was a valid token

Ginger

TIL

PyGamer0

@ophact any letter is a valid identifier

for example ones in the greek block

ophact

Includes Chinese letters etc?

PyGamer0

12:35

@ophact idk

and mathematical symbols are not valid identifiers

for example the summation symbol

Ginger

CMQ: Does anyone know of a good Python video-manipulation package? (like PIL but for video)

PyGamer0

but the capital greek sigma is valid

@Ginger ffmpeg?

ophact

@PyGamer0 The summation symbol is a greek capital letter.

pxeger

@Ginger I think there are ffmpeg wrapper libraries

ninja'd

Ginger

ffmpeg is the ImageMagick of video software

PyGamer0

12:37

@ophact no, summation has a separate codepoint assigned to it in unicode.
