Quick poll: of all the ways you could collaboratively work on a single file of code, what is the worst way you can think of?

Cause I think the way my group project has settled on might be the worst

Sʨɠɠan

@cairdcoinheringaahing network drives

Editing a file on a network drive all the same time is uuuuugh

@cairdcoinheringaahing what is it

IMO git would be the best, unless you want real-time collab

@user apparently scahla is correct, even if it comes from scalable

I will never stop saying scayla tho

Are gradle docs broken for anyone? If I try to interact with a page in any way other than scrolling it teleports me to the bottom

user

01:06

@cairdcoinheringaahing I've heard of email

Rydwolf Programs

@cairdcoinheringaahing The worst I can think of in a slightly different sense of worse would be timestamped diffs on a blockchain

Worse as in "I could actually imagine some moderately drunk college students persuading themselves it's a good idea"

Another one would be everyone using SSH to connect to the same TTY in a vim session. So you share a keyboard and monitor (and cursor).

Another would be a group chat where all of the messages are piped into ed

Unrelated String

ahahahahaha

that would be so fucked

Rydwolf Programs

I should learn to use ed, I've accidentally forgotten to install a text editor on really minimal linux distros before

The man page includes this:

> If the info and ed programs are properly installed at your site,

Feels so historical

user

@cairdcoinheringaahing NCIS-style, with multiple people typing on the same keyboard

Or semi-NCIS-style, with multiple people typing on their own keyboards, all hooked up to the same computer (kinda like Rydwolf's ssh idea)

Unrelated String

multiple people typing on one keyboard, hooked up to multiple computers

Rydwolf Programs

Redundancy is important

Who needs backups when you have two computers

Unrelated String

each computer individually has a 10% chance of ignoring any given keystroke to safeguard against catastrophic accidental inputs

Rydwolf Programs

Computers which tend to drop the wrong keystrokes get their OS reflashed out of spite, so they gradually face a selective pressure to become intelligent and learn which keystrokes are most likely to be mistakes

It helps that 10% of the hard drive is randomized upon startup to safeguard against critical software vulnerabilities

ATaco

Whilst generally Computers with different operating systems can't interface, Mac and Linux share enough code to allow for a non-viable distro.

Q: String Comparison

You are given two strings \$a\$ and \$b\$ consisting of characters from a to z in lowercase. Let \$n\$ be the length of \$a\$. Let \$m\$ be the length of \$b\$. Let \$a'\$ be the string \$a\$ repeated \$m\$ times. Let \$b'\$ be the string \$b\$ repeated \$n\$ times. Check whether \$a'\$ is lexico...

Lol there are 3 games where literally nobody got a date

user

How do you expect bots made by programmers to get dates?

mousetail

But a bunch of social awkward bisexuals in a room for long enough and at least one date is bound to come out of it normally

@mousetail You are supposed to golf :(

mousetail

05:57

It's golfed

TwilightSparkle

@ATaco :(

mousetail

but it's irreducable

TwilightSparkle

Alright, the intended answer is +[[->++>+<<]>]

One that probably would work for a nice cop in a C&R challenge

mousetail

This should also work right? -[-[->+<]>]

TwilightSparkle

@mousetail Ouch.

Go 191 cells then.

Jo King

06:00

@mousetail yeah, that's exactly what i thought of

mousetail

Any significance to the number 191?

TwilightSparkle

Oh, 191 doesn't work either.

It's at the same length.

I think.

Oh, it's not.

mousetail

My code uses the fact that 0-1 = 255 in brainfuck

Jo King

you could also use + of course

mousetail

Oh true, that could save 1 byte actually

No that would go 256 bytes instead of 255

TwilightSparkle

06:03

I will try to golf some more useful thing.

Jo King

@TwilightSparkle i'm pretty sure 50 bytes can be beaten btw, I think i have a bounty out on beating it

Jo King

@TwilightSparkle +[[>+++++<-]>+++++]>>>>

TwilightSparkle

@JoKing That's longer than fibonacci number.

Jo King

fibonacci doesn't have to terminate (the program you're thinking of doesn't output either)

@mousetail this is concerningly specific :p

mousetail

Do you have any experience to the contrary?

Ginger

no ~~but that's because I have no experience at all~~

mousetail

It's like the birthday problem, while for any one programmer them finding a date is highly unlikely, the chance that there exist 2 people who end up dating is quite high

Ginger

~~so you're saying there's a chance~~

mousetail

@Ginger Answer my KOTH and your bot can get a chance at least

It's just the thing where they enforce their trademark right? Like every other language already does

Yes, but they enforce it to an extreme

not even java disallows you from using their logo/name in your stuff

It's quite common to have similar clauses, but often they are not really enforced

@DLosc Not anymore.

YESSSSS

user

Ohmigod I can't wait for people to stop shitting on Java because Hello World takes more than a line

emanresu A

Finally I don't have to type public static void main(String[] argh)

user

Of course, schools and colleges won't use this for a very long time, by which time Java may not even be the preferred language for teaching CS anymore

emanresu A

Bet.

user

@emanresuA tbh I don't get why people complain about that. You only need to write it once in every application. There's a lot of other boilerplate Java has that's worth complaining about, but this is pretty minor

emanresu A

21:14

I'm doing a cs class right now, and I have to type that multiple times per assignment

user

oof

How?

DLosc

@user I don't mind that it takes more than a line, I mind that it takes a class definition and a System.out.println

user

Well this doesn't fix the System.out.println (which is a much bigger issue)

DLosc

Hello World in C is fairly reasonable IMO even though it's multiple lines

user

I do like that this toplevel method thing works for non-main methods too

I hate having to put everything inside a class

emanresu A

21:17

^

DLosc

^

Sʨɠɠan

System.out.println I rather like, tho having that + a normal println like Kotlin is fine too

@user sadly only in the main class. You can’t do that for arbitrary methods

user

Yeah it'd be nice if println and printf and print were imported by default

@Sʨɠɠan Oh

bruh

Then I am not such a big fan of this JEP

It makes the language less regular without adding a whole lot

Sʨɠɠan

I came to the same conclusion after thinking on it

> Henceforth, when the Java compiler encounters a source file with a method that is not enclosed in a class declaration it will implicitly consider such methods, as well as any unenclosed fields and any classes declared in the file, to be members of an anonymous main class.

user

Students will still have to suffer - there's classes still using Java 7

@Sʨɠɠan AAAHHHHH

Sʨɠɠan

21:19

so only in main classes, and no accessing methods in a different file

user

Wait it's not that big of an aaahhhh

But still weird

DLosc

More of an ᵃᵃᵃʰʰʰʰ then?

user

lol

Sʨɠɠan

aaahhh!?

wheres @Adám when you need his interrobang?

user

‽

DLosc

21:21

Can't you just Google it‽

Sʨɠɠan

I use se through curl, cant

DLosc

Ah, interesting

user

That reminds me, I need to make a CLI for SE

DLosc

@DLosc This is why "check mark" is one of my most frequent Google searches

user

If you want emojis, Win + . ought to help you

Sʨɠɠan

21:24

When you use dos

DLosc

I want the plain, non-emoji version ✓

user

Ah

DLosc

and so far the closest I've found in Win + . is √

but I might have skimmed over it

user

I thought it had Unicode too but I can't find it now :|

Sʨɠɠan

Also, Java is finally getting templated strings, although jankily openjdk.org/jeps/430

@DLosc see also

user

21:28

@Sʨɠɠan I guess the STR. is weird but it's understandable, it's lets people define their own template processors

It wouldn't be Java if it weren't at least 20% more verbose than other languages :P

This JEP looks interesting and useful ("Statements before super()")

DLosc

21:51

@Sʨɠɠan If you want to add to your weird square roots collection, you could check out the Square Root of Minus Garfield

Sʨɠɠan

22:04

@user YES I’ve been waiting for that

ive been abusing static methods way too long

@DLosc the 4th one is hilarious

Sʨɠɠan

22:23

@user Howd you find it

Ah there’s a draft section in the index

Neil

@DLosc I used to read it weekly but I forgot to keep up and I'm several months behind now

also, be glad it's not java.lang.System.out.println

DLosc

@Neil I love a good excuse for an archive binge

@Neil Surely you mean com.java.www.lang.System.io.out.println :P

Unrelated String

23:18

@user also an issue with the angle of gracefully onboarding new programmers without developing bad habits is they don't forbid the anonymous main class from having fields

lyxal

@user I think it will still be the preferred language

It has the perfect combination of OOP principles and simplicity for teaching

Unrelated String

the fields of an anonymous main class that gets instantiated exactly once are effectively global state, for a definition of global that doesn't extend to other classes because presumably when you're doing this you still don't have those

you shouldn't be allowed to have state that lives outside methods before you've started thinking about oop
