can u skip deep freeze with speed or no

05:29

and can u skip undeep too

05:31

i think u cant but want to make sure

@louis where is your aoc solution?

05:33

you seem to be online ^^

@heinrich5991 justatest

ill do it later

have you looked at the problem yet? it's not hard today

yeah but im lazy

05:34

and i suck at coding

k

like i know how to do it but idk any syntax

what language are you trying to use?

probs java/cpp

what language syntax do you know justatest

java/cpp

05:37

and teeworlds server settings if that counts as a language justatest

start with c its easier

1

no

llol

05:39

depends what ur doing i guess

05:39

i think its easier

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class day1 {
    public static void main(String[] args) throws IOException {
        Scanner s = new Scanner(new File("input"));
        List<Integer> l = new ArrayList<Integer>();
        while (s.hasNextInt()) {
            l.add(s.nextInt());
        }
        for (Integer i : l) {
            System.out.println(i);
        }
    }
}

05:40

@louis start here ^

05:41

this reads the list from the file into a java list

lol thx

05:41

saved me 5 minutes of googling probably

05:41

05:47

ok i got it

nice!

05:47

I just checke the leaderboard and you had silver

05:47

now you have gold

had some trouble cus im using some online java compiler so i had to change filename in scanner to system.in

05:47

lol

ah

javuis

Nope

never zoozed

@ᶰ°Konͧsti can u skip unfreeze

06:18

nvm

no

06:27

u cant skip any freeze related tile except with ninja

how tf do i this part?

Files.lines(Paths.get(file)).mapToInt(Integer::valueOf).collect(Collectors.toList()) streams make this even cuter

@Learath2 ur in java, u need to support java 1.5

12:32

Oh sorry

Meekrioz

how tf do i this part?

A bit late, but d+jump should do the trick

@Moderator can anyone come on 176.9.114.238:8323, there's a blocker

Please use #reports

@maggi323 ty ama helped me ig with it :)

@Learath2 oh, nice

15:50

I guess I'm not informed about the "latest" java style ^^

Java's streams are one of the few features that I actually like about it

I think I heard they don't play well with checked exceptions, unfortunately

Js' promises and observables. C#'s great data structures. Python's itertools. Are also examples of great features in languages I otherwise don't enjoy

heinrich5991

I think I heard they don't play well with checked exceptions, unfortunately

I never liked the concept of exceptions anyway, so I don't really mind

checked exceptions are the good kind of exceptions to me

15:56

because you're forced to handle/forward/raise a terminal signal if you have one

Exceptions decouple error handling, which is a no no for me

15:57

Context and locality are key to actually being able to handle errors. Just passing them on and on until the thing crashes is meh

with checked exceptions you have to at least think about whether you want your method to throw IOException or not, if you open a file

15:57

if you don't want that to happen, you have to handle it locally

15:58

unlike with unchecked exceptions, where exceptions are not furtherly checked by the compiler

I might be more open to exceptions with the strict rule that you cant forward them on

15:58

I also despise what exception handlers and the raising of exceptions does to the call stack in most languages

15:59

Debugging nightmare

I don't understand

15:59

having exception backtraces is a useful feature I miss in rust errors/C error handling

Those backtraces come at the cost of awful assembly

hm. do you mean missed optimizations?

A simple c++ function can compile to an unsightly mess

except for these missed optimizations, c++ exceptions are "free", I think

Well missed optimizations are one thing, but I also like to have sane assembly

16:02

They are indeed free in c++ so that is a plus

16:03

I think I posted a blog post that put my opinion on exceptions in nice words in #developer once, but I don't quite remember who wrote it

@Learath2 is the assembly really not sane? I thought c++ exceptions inspect the stack frames to find the exception handler

16:07

i.e. generating the same code for functions with/without exceptions (except for missed optimizations)

I think I posted a cppcon talk on how exception handling makes the smart pointers not quite zero cost which also illustrated how the resultant assembly is really not easy to reason about

16:09

But it's not that hard to experience for yourself, try observing the assembly generated for an exception aware program compiled with msvc

16:09

(clang is a bit better at generating cleaner assembly imo)

ah, but these are second-order effects

16:11

the smart pointer thing

16:11

I think that's also only a combination of "move constructors can throw" and "exceptions"

16:11

rust doesn't have move constructors, and I think smart pointers are zero (additional) cost

Well I don't like errors being handled at a stack frame that's any higher than the previous frame. So I don't like it's direct effects either

16:12

The smart pointer thing is just one example

Do u guys read assembly of ur programs?

16:12

Well when I'm debugging, certainly

Well u mustbe debugging rly complicated stuff then

https://godbolt.org/z/dajb19

Compiler Explorer - C++ (x86-64 gcc 10.2)

int throws() { throw new int; } int squared(int i) { if(i == 0) { throws(); } int result = i * i; if (result < 0) { return 0; } return result; }

16:13

no additional code in the squared function

Not really, the last 3 seriousish bugs I found in ddnet was through reading the assembly

https://godbolt.org/z/8eeoz3

Compiler Explorer - C++ (x64 msvc v19.27)

int throws() { throw new int; } int squared(int i) { if(i == 0) { throws(); } return i*i; }

16:15

same for msvc

I never see exceptions used in c+(

16:16

Not like i see lots of code anyway

I think our mysql lib throws

Observe how removing the exceptions gets rid of a lot of crust. In such a trivial example, yeah it's still well readable

you mean in the throws function? yes

16:17

in the squared function? not really

Well in the real world throws would not be it's own function

yes, just wanted to show that it only bloats functions mentioning throw or catch

Which should be most if not all functions if you are actually using exceptions in a way that allows error handling

16:20

(Rather than catchalls sprinkled at higher levels)

I see

@Learath2 do u like rust Result?

@Ryozuki yep, tho I'm not really sure how I feel about the ability to move it further up the stack

you mean that there's a short form for that?

In general I don't want errors moving up the stack at all. That's what leads to "unrecoverable errors" because you no longer have context to recover. In an "ideal" language I would want any further propagation to be explicit

I think it depends a lot how u code

Or maybe only a certain class of truly unrecoverable errors to be propagated

I'd argue that most of the time, even with sane error handling, you want the error to move up the stack

U can still panic()

e.g. check the rust standard library

I don't see much point in it moving higher than 1 frame implicitly

What about a web framework, u can return the error up the stack and it would handle any error by returning a proper response

it's not implicit in rust, you add a ?

16:27

(previously, it was a if_ok! macro)

16:27

I like that it's easier to propagate the error than to ignore it, for once

Well it's a shorthand, shorthands usually imply some behaviour is condoned

much better than the style that C encourages and teeworlds embraces

16:28

the shorthand there is: doing nothing with the result

return -1;

16:28

@heinrich5991 you move it up the stack but do you really handle it? How many programs just crash with an unhandled exception? Or even worse catch-alls that have no way to handle the exception but to ignore or log and crash?

Thats not langusge fault

crashing the program is better than silently dropping errors IMO

Its urs for being lazy

E.g. the crash in ddnet when you run it with app verifier

16:30

It's an ignored exception that no one noticed in sdl2

16:30

Well probably actually in nvidias driver

Nvidia fix ur shit!

16:30

Linus

@Ryozuki I'd argue that it is indeed the languages job to keep me safe, especially if it's claiming to be safety oriented

do you agree that C fairs much worse here, encouraging to ignore errors instead of crashing on unhandled errors?

16:31

*fares?

Definitely fares much worse

No, C is holy and perfect

16:33

✝️

Well ofc not, now you are being silly

Yeah im joking

16:33

C does just what you tell it to do. When an error is not handled properly it's always a 100% of the time the programmers fault

Well doesnt that apply to all languages

it'd be nice if C did what you told it, but that's another story

Eh, not all. C++ has a lot of hidden code. D has hidden code. ObjC has hidden code and even runtime monkey patching.

heinrich5991

it'd be nice if C did what you told it, but that's another story

I like RAII-style hidden code

You don't quiiite ever know what is crashing. Is it the hidden code injected by the language. Is it monkey patched compatibility routines? Did the exception muck up my stack to make it impossible to debug my issue?

hm. maybe not RAII

16:36

but I like destructors running without me calling them

With destructors u cant forget about freeing but u can free it willingly too

16:38

I find that good

One thing I would want in C++ is constructors returning an optional. It'd be nice to have failing constructors without the silly boolean with init function or exceptions.

you can simulate that with a static member function

16:38

much like rust does, except it doesn't even have constructors

Yeah but language support would be cuter

I love rust for that, u implement a new() and ur not forced to return the same typw

16:39

Rust enums are dope

If only rust was unsafe and had a non silly syntax, it really sounds like it has features I would enjoy

Been using zig for a couple things and that is really one well designed language, even with optional runtime safety

I wonder why no one designed a lang that fits learath2, u must be unique in this world

@Basic Jeff what you streaming?

apparently zig fits him(?)

@Ryozuki zig and D seem to be designed by likeminded people :P

16:42

Nim feels like a saner performant version of python. Those are the 3 modern languages I sort of enjoy working with

I only tried a little D, looked like some modern C

it's spawn blocking

17:07

@Fera then ban the bot

17:07

Bruh took you long enough xD

@Learath2 constructors returning some optional is terrible idea, because it leads to "if-madness"

17:08

just look at C

what's if-madness?

manually checking all results with "if" statement

17:09

carefully used exceptions are much better i think

ah

17:10

I think Learath2 disagrees on this ^^

the only problem is that standard library exceptions in C++ are so bad

whats a switch checker

Yeah we fundamentally disagree. I love the ifs that you think are madness

@plsplsplslol checks how many switches out of 8 are open

18:53

i don't see it being disrespecting if it is not aimed at them

dont use

@Alifty so ?

dont work

18:54

me close

@Alifty okay other than that i can't help i suggest u try asking @heinrich5991 For help

Use DDNet client, press Esc and click on "Connect Dummy"

me can join ito ddnet client

report racist names to mods

you should be automatically kicking people with names like that

Iza

you should be automatically kicking people with names like that

its hard to automatically kick those types of names, you need a mod for those people

or name filter, which will unleash full power of comunitty trolls feelsamazingman

(edited)

Just insert roblox filter

bruh u guys get the point its targeting a certain group of people

How is red hair a race

its not about what fits the definition of a race

23:30

having ppl run around with insulting names doesnt do any good

23:30

less ppl will play if they see that the servers are full of toxic people and nobody moderates it

so insulting 0.7 players is also bad then

u arent born as a 0.7 player

23:33

so no its ok, 0.7 sucks greenthing
