I mean the mute/ban without a notification to the target. 15:49 < bridge_> I see you want to be clear for the players but let's be fair — we're not capable to deal with all spammers. They use "unfair" techniques and we have to spend a lot of energy fighting with them. 15:49 < bridge_> 15:49 < bridge_> For example, I suggest to add text-based shadow mute. This way we can add an advertising message to an auto-mute list and calm down the spammers. It is much easier for them to detect 'clear' bans and 'mutes' and rotate IPs / join another servers. On the other hand, it is hard for us to manually mute all the bots. 15:49 < bridge_> Instead on the ddnet level it can be "`for server in all_servers: econ block_message "EVERYONE GO TO THIS SERVER FAST! LET'S MAKE THE MEAT!!!" 600 "new spam"` putting all whoever say this in a 10 minutes shadow mute, so other players won't see any message from those who are muted but the muted players 'll receive proper chat respond from the server. 15:49 < bridge_> 15:49 < bridge_> It 'll take time for the spammers to beat it (though I see how to overcome it). 15:51 < bridge_> Another "unfair" feature is name-based shadow autoban. 15:51 < bridge_> Use-case: there was a racist person (maybe you 15:51 < bridge_> @ryozuki do you know if there is something like `str_utf8_forward` in Rust? 15:51 < bridge_> shadow banning 15:52 < bridge_> what does str_utf8_forward 15:52 < bridge_> Skips n utf8 codepoints 15:52 < bridge_> I guess I could (ab)use an iterator 15:52 < bridge_> Another "unfair" feature is name-based shadow autoban. 15:52 < bridge_> Use-case: there was a racist person (maybe you've seen/remember him — `elban`). I banned him, he reconnected from a different IP. And then it repeated like 10 times, until one of us gave up. 15:52 < bridge_> He connected with the same username, and noone else used that name, so this could be automated. 15:52 < bridge_> @learath2 isnt the chars iterator that 15:53 < bridge_> i dont remember but i think they are graphemes 15:53 < bridge_> or smth 15:53 < bridge_> https://doc.rust-lang.org/std/primitive.str.html#method.chars 15:53 < bridge_> > Returns an iterator over the chars of a string slice. 15:53 < bridge_> > 15:53 < bridge_> > As a string slice consists of valid UTF-8, we can iterate through a string slice by char. This method returns such an iterator. 15:53 < bridge_> > 15:53 < bridge_> > It’s important to remember that char represents a Unicode Scalar Value, and might not match your idea of what a ‘character’ is. Iteration over grapheme clusters may be what you actually want. This functionality is not provided by Rust’s standard library, check crates.io instead. 15:53 < bridge_> Doubt they are graphemes, graphemes are extremely hard to decode, require a massive table 15:53 < bridge_> Yeah regular codepoints is what I want anyway 15:53 < bridge_> then its that ye 15:53 < bridge_> Another "unfair" feature is name-based shadow autoban. 15:53 < bridge_> Use-case: there was a racist person (maybe you've seen/remember him — `elban`).

We can just ignore/drop his network packets without a reply. 15:54 < bridge_> u can make the iterator peekable() 15:54 < bridge_> I need to keep track of my byte position through the string aswell 15:54 < bridge_> So I guess a peekable char_indices 15:54 < bridge_> Was just wondering if there was a more non-iterator way to do it 😄 15:55 < bridge_> https://doc.rust-lang.org/std/primitive.str.html#method.char_indices 15:55 < bridge_> i mean good thing about iterator is u dont have to allocate a vec 15:56 < bridge_> Problem with iterator is when I read a character there is no going back without making it peekable, but with a peekable iterator I can't use all the cool functions like `.skip_while()` 15:56 < bridge_> Anyway, I'll just do one loop and not use the cool functions I guess 15:57 < bridge_> @learath2 check if itertools has what u want 15:57 < bridge_> https://docs.rs/itertools/latest/itertools/ 15:57 < bridge_> Ah, I'd forgotten it was a thing in rust aswell 15:58 < bridge_> https://docs.rs/itertools/latest/itertools/trait.Itertools.html#method.peeking_take_while 15:58 < bridge_> it has some take whiles 15:58 < bridge_> Exactly what I'm looking for 15:59 < bridge_> Thanks Rustman 15:59 < bridge_> np 16:00 < bridge_> btw a neat thing i discovered recentely 16:00 < bridge_> I wonder if there is any overhead fo peekable, it should be free for iterating arrays if specialized enough 16:00 < bridge_> if u have a iterator over options 16:00 < bridge_> u can filter all nones with .flatten() 16:00 < bridge_> its pretty neat 16:00 < bridge_> Ah yep, I've used this before 16:01 < bridge_> ```rust 16:01 < bridge_> impl MyHashmap 16:01 < bridge_> where 16:01 < bridge_> K: Eq + Hash, 16:01 < bridge_> S: BuildHasher, 16:01 < bridge_> { 16:01 < bridge_> fn resize(&mut self) { 16:01 < bridge_> let new_storage: Vec> = 16:01 < bridge_> (0..self.storage.len() * 2).map(|_| None).collect(); 16:01 < bridge_> 16:01 < bridge_> // Replace the storage with the new one, so we can use self.x methods to rehash. 16:01 < bridge_> let old_storage = std::mem::replace(&mut self.storage, new_storage); 16:01 < bridge_> 16:01 < bridge_> self.len = 0; 16:01 < bridge_> 16:01 < bridge_> for (k, v) in old_storage.into_iter().flatten() { 16:01 < bridge_> self.insert(k, v); 16:01 < bridge_> } 16:01 < bridge_> } 16:01 < bridge_> } 16:01 < bridge_> ``` 16:01 < bridge_> i used it on my blog post 16:01 < bridge_> and i discovered this thanks to... 16:01 < bridge_> clippy! 16:02 < bridge_> :gigachad: 16:02 < bridge_> Did it get Fame? 16:02 < bridge_> What was the Reddit link again 16:02 < bridge_> it reached frontpage for some time 16:02 < bridge_> https://www.reddit.com/r/rust/comments/14vtc8f/implementing_a_simple_hashmap_in_rust/ 16:02 < bridge_> it has some comments 16:02 < bridge_> but im lazy rn to address them 16:02 < bridge_> one is rly nice 16:02 < bridge_> the one mentioning the cycles 16:03 < bridge_> https://cdn.discordapp.com/attachments/293493549758939136/1129050353069998191/image.png 16:03 < bridge_> these are the stats 16:03 < bridge_> from reddit 16:04 < bridge_> @ryozuki any idea what the best way would be to consume all? 16:05 < bridge_> google search 16:05 < bridge_> https://cdn.discordapp.com/attachments/293493549758939136/1129050886858080349/image.png 16:05 < bridge_> I don't need what I take technically 16:05 < bridge_> consume? 16:05 < bridge_> skip? 16:05 < bridge_> technically collect consumes all xd 16:05 < bridge_> <_voxeldoesart> what does this do 16:06 < bridge_> Yes, but there is no `peeking_skip` so I need to discard what I get from `peeking_take_while` 16:07 < bridge_> resizes the hashmap 16:07 < bridge_> using mem replace for minimum copies 16:08 < bridge_> <_voxeldoesart> weird 16:08 < bridge_> i dont get it much 16:08 < bridge_> maybe example 16:08 < bridge_> whats weird 16:10 < bridge_> ```rust 16:10 < bridge_> fn foo(s: &str) { 16:10 < bridge_> let mut it = s.char_indices().peekable(); 16:10 < bridge_> it.peeking_take_while(|(u, c)| { c.is_whitespace() }) 16:10 < bridge_> } 16:10 < bridge_> ``` 16:10 < bridge_> I now need to consume all of the new iterator `peeking_take_while` returned 16:11 < bridge_> ah 16:11 < bridge_> dont u simply want to filter? 16:11 < bridge_> tell me what u want to do with the chars 16:11 < bridge_> No, I technically just need `peeking_skip` I need to skip all whitespace without consuming the first non-whitespace character 16:12 < bridge_> filter doesnt consume non filtered iirc 16:12 < bridge_> `it.filter(|x| x.is_whitespace() )` with this u have a iterator over non whitespace chars 16:12 < bridge_> hi 16:14 < ChillerDragon> coberfita 16:14 < bridge_> can we have a public archive for reports since its private rn (unless its already public and i havent found it) 16:14 < bridge_> I had this idea aswell but I can't just iterate over non whitespace, I need to know where the whitespaces are. I'm rewriting my lexer 16:14 < bridge_> why u writing a lexer 16:14 < bridge_> use logos 16:14 < ChillerDragon> why you writing a hashmap 16:14 < bridge_> https://docs.rs/logos/latest/logos/ 16:14 < bridge_> This I why I asked an XY question instead of telling you exactly what I'm doing 😄 16:14 < bridge_> xd 16:14 < bridge_> hmm 16:15 < bridge_> maybe some fold where the acc is a storage of whitespace indexes or smth 16:15 < bridge_> but logos will be faster than anything u write by hand 16:15 < bridge_> atleast thats what they claim 16:15 < ChillerDragon> ethos 16:15 < ChillerDragon> pathos 16:15 < ChillerDragon> logos 16:15 < bridge_> https://cdn.discordapp.com/attachments/293493549758939136/1129053591152361632/image.png 16:15 < bridge_> cute logo too 16:16 < bridge_> I'm just trying to get more comfy with rust, using a lexer generator won't help 16:16 < bridge_> just make 2 iterators? 16:16 < bridge_> one for whitespaces one for none 16:16 < bridge_> or simply do a for loop 16:16 < ChillerDragon> ryo send like on gh issue pls 16:16 < ChillerDragon> https://github.com/PathosEthosLogos/Leave-a-message-beep/issues/1 16:16 < ChillerDragon> i need attention from this guy 16:17 < ChillerDragon> he creator of logos 16:17 < bridge_> <_voxeldoesart> idk im just dumb 16:17 < bridge_> @learath2 ur gonna need to save the whitespace indexes so 16:17 < bridge_> make a hashset and save the indexes there 16:17 < bridge_> well 16:17 < bridge_> a vec 16:17 < bridge_> the indexes will be unique anyway xd im dum 16:18 < bridge_> no u just need to learn rust 16:19 < bridge_> @learath2 what about https://docs.rs/itertools/latest/itertools/fn.multipeek.html 16:20 < bridge_> I don't need to peek further than one 16:20 < bridge_> On a scale of 0-10, how ugly is just doing `.for_each(|_| {})` on the `PeekingTakeWhile`? 16:21 < bridge_> i usually use for loops inteast 16:21 < bridge_> instead 16:21 < bridge_> So just a for loop with an empty body? 16:21 < bridge_> whait 16:21 < bridge_> thats ugly 16:22 < bridge_> im still confused 16:22 < bridge_> idk if im an idiot 16:22 < bridge_> Or I guess I could do this the ancient way, just not have it peekable and have one big state machine handle everything 16:22 < bridge_> you want to save all whitespace ranges? 16:22 < bridge_> Noo, it's probably my ancient coding style that doesn't match with your mental image of what I'm doing 16:22 < bridge_> I want to skip the whitespace, nothing more 16:22 < bridge_> but then why no filter? 16:23 < bridge_> wtf LOL 16:23 < bridge_> I want to skip the whitespace until the first non-whitespace, then I need to do other stuff that require me to no longer ignore the whitespace 16:23 < bridge_> @_voxeldoesart did u make the new banners in welcome channel 16:23 < bridge_> If I have a filtered iterator I can't unfilter it after I hit the first non-whitespace 16:23 < bridge_> ahh 16:24 < bridge_> https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.skip_while 16:24 < bridge_> this ? 16:24 < bridge_> > Creates an iterator that skips elements based on a predicate. 16:24 < bridge_> > 16:24 < bridge_> > skip_while() takes a closure as an argument.
