The Nineteenth Byte

5:21 PM

A group of sophomores I'm sitting across from came across an instruction manual for a projector and they've spent the last 10m laughing at the phrase "insert the dongle"

pxeger

why do you have such strange words for the year groups

what is a sophomore

what are you

Radvylf Programs

10th grade

pxeger

apparently, sophomore generally means "the second in a series", but it can also mean "a 3-year-old horse"

its etymology is "wise fool" ???

Radvylf Programs

9th: Freshman
10th: Sophomore
11th: Junior
12th: Senior

pxeger

> Freshmam

is "mam" the gender-neutral term for "man" now?

Radvylf Programs

5:28 PM

We're actually all just three year horses

@RadvylfPrograms the lesser-known cousin of the 17-year cicada

Radvylf Programs

Currently trying to figure out a google foobar thing that I'm like 20% sure is totally impossible

Ginger Industries

hot take: google foobar is just fancy nerd-sniping

Radvylf Programs

it involves taking the sum of 10^100 items and I can't find any way to do it faster than O(n) for the sequence

Ginger Industries

i'm trying to fix ambiguity in the Dynalist syntax

pxeger

TIL you can close the implicit while (<>) { ... } block that perl -n gives you: ato.pxeger.com/…

@RadvylfPrograms does the sequence have any special properties you can exploit?

Radvylf Programs

5:49 PM

Tryna figure that out

It's floor(n*sqrt(2))

Ginger Industries

hmmm

Radvylf Programs

OEIS has nothing useful

Ginger Industries

hmmmmmm

pxeger

if it weren't for floor, you could factor out the *sqrt(2) to get sum(1..10^100) * sqrt(2)

Ginger Industries

hmmmmmmmmmmmmmmmmmmmmmm

ok time to go screw with the parser

pxeger

5:51 PM

also:

> While you were away, the last challenge timed out

Ginger Industries

@pxeger i guess you... WEREN'T RESPONDING

RIMSHOT

Unrelated String

yeah that really looks... unfriendly

Ginger Industries

how do I tell ply that "if this statements is followed by another statements then require a semicolon in between"

hmmmm

pxeger

what parsing system are you using?

Ginger Industries

ply

Python Lex-Yacc

the problem I have is as follows:

take the code ?1234. if ? evaluates to true, I want it to run commands 1 and 2, otherwise 3 and 4. but the problem is, the parser has no way to tell that. for all it knows, I might want it to run 123 if true and 4 if false.

pxeger

5:56 PM

you need some grouping then

I really don't think lex+yacc is the best way of doing this

Ginger Industries

the solution I have come up with is to use semicolons, i.e. ?12;34

wait i think i know how to do this

hold please

pxeger

@GingerIndustries do you want the ;34 to be optional?

Unrelated String

i feel like we
may need to know more about the surrounding syntax
as well

pxeger

because if so, then what does ??12;34 result in

Ginger Industries

im working on it

pxeger

5:58 PM

(spoiler alert: shift-reduce conflicts)

Ginger Industries

that's exactly what happens

and my solution is: ?(12)(34)

pxeger

that's not very golfy

Ginger Industries

yup

Radvylf Programs

It sounds like you should use prefix or postfix

Ginger Industries

so i'm trying to smallify it

Radvylf Programs

5:59 PM

With prefix/postfix there'd be no separators needed

Ginger Industries

@pxeger the correct grammar for something like that would be ‽?12;34

because ‽ is the monadic if

Radvylf Programs

The frick is a monadic if

pxeger

if, but with no else clause, I'm guessing

Ginger Industries

yup

Radvylf Programs

Oh, so the monadic part isn't including the condition

Unrelated String

6:00 PM

if it returns something then ah nvm

Ginger Industries

hmm

Seggan

With ANTLR you got monadic_if: '?' statement (':' statement)? ;

pxeger

@Seggan how will that handle ??12:34?

CMQ: if (+) is lambda x, y: x + y, should (=) be anything other than an error? (= is assignment)

Ginger Industries

laughs in WARNING: 176 shift/reduce conflicts

Radvylf Programs

@GingerIndustries ?

Oh I get it now lol

mathcat

6:15 PM

@GingerIndustries 1 2+

Ginger Industries

6:39 PM

idea for Dynalist: special variables

you can access them with superscript numbers

they have different values depending upon what's happening in the program

like in a loop, one might be how many times the loop has gone around

Adám

@pxeger Why not let it take the target name as a string?

pxeger

@Adám because it's a compiled language

Adám

Good reason.

emanresu A

6:55 PM

@pxeger I read that as "You've done a negative number of edits?"

pxeger

I think it was just shouldiblamecaching.com

they both say 101 now

Ginger Industries

there is ostensibly a LYAL going on but nobody's really learning anything

ah well

emanresu A

@pxeger Copy maybe?

TIL hello, world!

o/

pxeger

\o

Seggan

@pxeger It'll say "unexpected token '?' at 1:1"

if you want it to handle 2, just do `monadic_if: '?''?'? statement (':' statement)? ;

pxeger

7:09 PM

I mean if statement: ... | monadic_if

Seggan

I don't follow

a monadic if right after a ? statement?

pxeger

if monadic_if is allowed as one type of statement

Seggan

itll parse it correctly

i can write up a sample antlr grammar and test it if ya want

pxeger

@Seggan but will it parse as ?(?12:34) or ?(?12):34

Seggan

lemme test

oof hard to see

basically, ?(?12:34)

pxeger

7:18 PM

codegolf.meta.stackexchange.com/a/24328 - what happens if this stays tied?

Radvylf Programs

They get 250 each I guess

pxeger

ah, didn't think of that ;)

caird coinheringaahing

Or hyper, being the only person who can't vote, can cast a tiebreaker

Ginger Industries

8:06 PM

CMQ: Is this an acceptable output format for a list of truthy/falsy values? [True, 0.0, 0.0, 1.0, 0.0]

pxeger

is True == 1.0 in this language?

Ginger Industries

1.0 is a truthy value

pxeger

(what language is it?)

Ginger Industries

Dynalist

there are some quirks with how it handles boolean inputs

pxeger

@GingerIndustries I mean, does the equality operation, when given True and 1.0, give True?

Ginger Industries

8:08 PM

@pxeger yes

pxeger

then it probably is

Ginger Industries

ok

Unrelated String

@pxeger if there are lvalue references it could take those on the left but if you're asking then i assume there aren't

pxeger

@UnrelatedString actually, that's kind of a good point; it has boxes (basically safe pointers), so it could mean writing

Unrelated String

ooh

yeah that could work then

pxeger

8:18 PM

although it might be a bit inconsistent that it's *x = y but (=)(x, y)

Unrelated String

@GingerIndustries i think 05ab1e has two different contextual/loop variables; can't remember why but you might want to give them a look

yeahh

Radvylf Programs

I don't get the point of high resolution laptop screens

Unrelated String

for if you want high resolution but cba to use a separate monitor :P

Radvylf Programs

You always just have to scale them down in settings, and that's usually even done as the default option.

pxeger

how high resolution, and how big?

4k on a 13", definitely overkill

1440p on a 16", probably useful

Radvylf Programs

8:20 PM

E.g., my new chromebook is 2256x1504

Unrelated String

i know there are 4k 17"s

Radvylf Programs

I know you had the option to get my last laptop in 4k 13"

Anything more than 1080p is totally unnecessary for a 12"-14" screen IMO

Unrelated String

@RadvylfPrograms that... doesn't seem too nice with normal resolutions

Radvylf Programs

@UnrelatedString It's 3:2

It feels weird at first, but it's actually really great

You can fit way more terminal lines/code/TNB messages/pages of google docs/PDFs on screen at once

Ginger Industries

how many of the above can you fit at once

Radvylf Programs

8:22 PM

83 lines of code

Ginger Industries

wow

Radvylf Programs

An entire page of a google doc without scrolling

Same with PDFs

Unrelated String

damn

Ginger Industries

.o.

Radvylf Programs

My terminal font size is the same as my code editor so 83 lines there

And I currently have 30 TNB messages on screen

Ginger Industries

8:25 PM

amazement

Unrelated String

still not a nice multiple of common video resolutions but that does sound nice

Bgil Midol

@RadvylfPrograms i have 15

Radvylf Programs

Yeah you get letterboxing for basically every video aspect ratio in common use, but I rarely watch stuff in full screen anyway

Ginger Industries

imagine using 1920x1080
made by 1320x42 gang

Radvylf Programs

Lyxal prolly uses 420×69

Unrelated String

8:27 PM

@RadvylfPrograms i'd be worried about weird scaling more so than letterboxing

Ginger Industries

and then of course you've got the rgb light strip guys and their 10000x1 screens

Unrelated String

but it's probably not too noticeable

Radvylf Programs

I've never experienced anything being stretched or anything

But like I said I usually don't full screen stuff anyway lol

Unrelated String

lol

Radvylf Programs

Ooh I've pulled ahead of caird for most FA/FQ reviews

So I have more than any other user on the site, with caird being close behind and everyone else at about half of our amounts

Unrelated String

8:30 PM

nice

Bgil Midol

nice

Ginger Industries

nice

Unrelated String

@RadvylfPrograms come to think of it i probably do an abnormally large amount of full screen video watching since i almost never watch things on my tv

caird coinheringaahing

@RadvylfPrograms I've been busy the last 4 days :(

You can tell, I'm only in 4 of the "last reviwers" things

Ginger Industries

imagine using a monitor
made by SpaceX MindLink™ gang

pxeger

8:34 PM

@RadvylfPrograms wow, on my 26" monitor (1080p) I only get 54 rows

Unrelated String

my 1080p 15" does less than that since i have 125% text scaling enabled by the os lmao

Unrelated String

yt comments are
quite special

Radvylf Programs

Just came across a comment on a video, which was enthusiastically agreeing with the main point, and providing an example (it was a rather political topic) from the user's home country. And one of the replies (with hundreds of likes) was like "best comment on this awful video, completely destroyed their point"

Unrelated String

phenomenal

DLosc

Replied to the wrong comment, maybe?

(doesn't explain the likes, tho)

Radvylf Programs

11:36 PM

Nope, because it was followed up by a discussion including that same user, discussing the point the original comment had made

Unrelated String

i take it that discussion also excludes the possibility that it was some very weak joke

yeah
