02:24 < bridge> <var4ik_va1l> help guys, I'm starting the game, everything is lagging, the laptop is new, I don't know what to do
03:06 < bridge> <Ewan> @var4ik_va1l #general
03:35 < bridge> <Tyrone> answer is 4902
03:35 < bridge> <Tyrone> thank me later
05:42 < ws-client> <ChillerDragon> assembly is clearly for maffs genius
05:43 < ws-client> <ChillerDragon> i debugged 10 minutes because i assumed 14 - 8 is 8
06:06 < bridge> <Ewan> lmao
07:53 < bridge> <ryozuki> :justatest:
08:25 < bridge> <milkeeycat> first time had to use lifetimes in rust, i feel so smart rn xd
09:31 < bridge> <milkeeycat> @learath2 they are not read only anymore! 🎉

09:43 < bridge> <milkeeycat> maybe it's time to write some tests :justatest:
09:51 < ws-client> <ChillerDragon> is it weird that i somehow desire all features in the tw protocol that browsers and http have?
09:51 < ws-client> <ChillerDragon> I really wish a client would send its supported compression alorithms to the server and the server only uses those.
09:52 < ws-client> <ChillerDragon> So if a client does not support huffman the server just does not send huffman compressed payloads
09:53 < ws-client> <ChillerDragon> Implementing huffman is the worst
09:54 < bridge> <louis> write only no read
09:55 < bridge> <milkeeycat> hm?
10:03 < ws-client> <ChillerDragon> woah gcc is doing some dances when i try to multiply something xd
10:03 < ws-client> <ChillerDragon> @milkeeycat how did you implement multiply in your language?
10:04 < ws-client> <ChillerDragon> apparently `mul` is slow ...
10:05 < bridge> <milkeeycat> chillerdragon: https://github.com/MilkeeyCat/meraki/blob/8f76c9d853d47f3e2dc2f69049c909d694ea9ac4/src/archs/amd64.rs#L132 `imul` xd
10:06 < ws-client> <ChillerDragon> that just works like i assume it works?
10:06 < ws-client> <ChillerDragon> `imul rax, 2`
10:06 < ws-client> <ChillerDragon> multiplies what is in rax by 2 and stores the result in rax?
10:07 < bridge> <milkeeycat> > Two-operand form — With this form the destination operand (the first operand) is multiplied by the source operand (second operand). The destination operand is a general-purpose register and the source operand is an immediate value, a general-purpose register, or a memory location. The intermediate product (twice the size of the input operand) is truncated and stored in the destination operand location.
10:07 < bridge> <milkeeycat> https://www.felixcloutier.com/x86/imul
10:07 < bridge> <milkeeycat> 
10:07 < bridge> <milkeeycat> it should work like that, yea xd
10:15 < ws-client> <ChillerDragon> So weird that there is `mul` and `imul`
10:15 < bridge> <milkeeycat> for signed and unsigned multiplications
10:15 < bridge> <milkeeycat> for signed and unsigned multiplication
10:15 < ws-client> <ChillerDragon> I can just add with `add` but somehow i need fakin imul
10:16 < ws-client> <ChillerDragon> so imul is signed?
10:16 < ws-client> <ChillerDragon> seems nice i dont think i will ever use anything other than `imul` then
10:16 < bridge> <milkeeycat> yep
10:16 < ws-client> <ChillerDragon> new instruction unlocked
10:16 < bridge> <milkeeycat> i use `imul` even for unsigned numbers
10:16 < ws-client> <ChillerDragon> <:poggers2:1008007455936094328>
10:17 < bridge> <milkeeycat> lea rath, 2 said it's gud
10:17 < ws-client> <ChillerDragon> pog
12:44 < bridge> <learath2> there is some caveats that I really cba to re go into, you can google or search this channel
12:46 < bridge> <heinrich5991> cool, thanks for sharing!
12:48 < bridge> <heinrich5991> they'd also be distrusted if they'd do that (at the very least, that'd happen for turkey)
12:50 < bridge> <heinrich5991> ChillerDragon: if you multiply with a constant, you can often transform it into a `lea` or some shifts plus additions
13:27 < bridge> <learath2> @heinrich5991 do you happen to know if an url lacking the host part is still a valid url?

15:22 < bridge> <learath2> @heinrich5991 would you prefer `<c="#F00"><b>text</b></c>` or `<c="#F00" b>text</>`?
15:24 < bridge> <archimede67> second looks horrible and doesn't make sense
15:24 < bridge> <archimede67> second one looks horrible and doesn't make sense
15:24 < bridge> <archimede67> second one looks horrible and doesn't make sense imo
15:24 < bridge> <learath2> Yeah, but it's slightly easier to parse 😄
15:30 < bridge> <heinrich5991> first one
15:49 < bridge> <ryozuki> https://cdn.discordapp.com/attachments/293493549758939136/1268928630411493436/GT7VdwEWUAAheSv.png?ex=66ae3561&is=66ace3e1&hm=6d3b4a0637a661f49aa4182e380d2edbac31937619682a511a242599a4efeb00&

15:51 < bridge> <heinrich5991> > ## Why Learn This Stuff?
15:51 < bridge> <heinrich5991> > 
15:51 < bridge> <heinrich5991> > Every introduction to every compiler book seems to have this section. I don’t know what it is about programming languages that causes such existential doubt. I don’t think ornithology books worry about justifying their existence. They assume the reader loves birds and start teaching.
15:56 < bridge> <learath2> I'm guessing we also want `&lt;` and `&gt;` and `&amp;` hm, maybe they are right about this being annoying
16:00 < bridge> <heinrich5991> using strict parsing and thought-out stuff can be a little bit more annoying in the short term
16:00 < bridge> <heinrich5991> but we'll thank us later, because it'll be a lot less annoying in the long run
16:01 < bridge> <learath2> I was planning to hand roll a parser but maybe I should generate one with bison or sth
16:01 < bridge> <heinrich5991> seems fine to hand-roll a parser here
16:02 < bridge> <heinrich5991> what do we need to match on? `<`, `&`, everything else
16:02 < bridge> <heinrich5991> discard any message that doesn't follow this format
16:02 < bridge> <learath2> I was planning to just fall back to non-rich text if parsing fails so atleast the broken string is displayed as plaintext
16:03 < bridge> <heinrich5991> I'd prefer not to
16:03 < bridge> <heinrich5991> at least on the network layer
16:03 < bridge> <heinrich5991> on the network layer, there IMO should be a flag that tells the client whether this is rich text or not
16:04 < bridge> <heinrich5991> and the message is just discarded if rich text is enabled and does not parse
16:04 < bridge> <heinrich5991> on the network layer, there IMO should be a flag that tells the client whether this is rich text or not (default off, backcompat with old servers)
16:04 < bridge> <learath2> Here is kinda what I'm thinking in terms of format btw
16:04 < bridge> <learath2> https://cdn.discordapp.com/attachments/293493549758939136/1268932518640619562/image.png?ex=66ae3900&is=66ace780&hm=6260cecbe68a845c5dc614d47e82c465bb24b0755362128bf39bc786cc82b472&
16:05 < bridge> <heinrich5991> can you give me the original link? it's very small

16:07 < bridge> <learath2> Though this is before I remembered we need to handle escapes, so that'll probably need some thinking on my part 😄
16:08 < bridge> <learath2> Rendered it bigger if anyone else doesn't want to bother

16:09 < bridge> <ryozuki> what u working on=?
16:09 < bridge> <ryozuki> rich text for tw?
16:09 < bridge> <learath2> Yes
16:09 < bridge> <learath2> I was going to just leave it to someone else but got the urge to write a parser 😄
16:12 < bridge> <learath2> Actually this doesn't look correct, doesn't allow nesting, this one was the original one I made
16:14 < bridge> <ryozuki> found it on twitter as a image so i didnt know source
16:15 < bridge> <heinrich5991> ```ebnf
16:15 < bridge> <heinrich5991> text = {?char? | ampersand_escape | color_tag};
16:15 < bridge> <heinrich5991> 
16:15 < bridge> <heinrich5991> ampersand_escape = '&amp;' | '&lt;' | '&gt';
16:15 < bridge> <heinrich5991> color = [hexdigit, hexdigit, hexdigit] | [hexdigit, hexdigit, hexdigit, hexdigit, hexdigit, hexdigit];
16:15 < bridge> <heinrich5991> color_tag = ['<c=#', color, '>', text, '</c>'];
16:15 < bridge> <heinrich5991> hexdigit = '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' | 'a' | 'b' | 'c' | 'd' | 'e' | 'f' | 'A' | 'B' | 'C' | 'D' | 'E' | 'F';
16:15 < bridge> <heinrich5991> ```
16:15 < bridge> <heinrich5991> @learath2 I'd be much more specific in what to accept
16:17 < bridge> <heinrich5991> https://cdn.discordapp.com/attachments/293493549758939136/1268935803707326464/image.png?ex=66ae3c0f&is=66acea8f&hm=90209bd1b52b396c2b1fa25eeb7178d7d4869b483084c303a0fb50697f710929&
16:17 < bridge> <learath2> Do we want quotes around the color?
16:19 < bridge> <heinrich5991> dunno. we're not actual xml because the a tag can't have a value
16:19 < bridge> <heinrich5991> so it doesn't really matter I guess?
16:19 < bridge> <heinrich5991> dunno. we're not actual xml because a tag can't have a value there
16:20 < bridge> <learath2> btw you probably want `color = hexdigit, hexdigit, hexdigit, [hexdigit, hexdigit, hexdigit]` or `color = {3 * hexdigit} | {6 * hexdigit}`
16:21 < bridge> <heinrich5991> true. still learning the syntax
16:22 < bridge> <learath2> btw you probably want `color = hexdigit, hexdigit, hexdigit, [hexdigit, hexdigit, hexdigit]` or `color = {3 * hexdigit}- | {6 * hexdigit}`
16:22 < bridge> <learath2> heh I had it wrong too with the numerical repetition
16:23 < bridge> <learath2> `color = 3 * hexdigit | 6 * hexdigit`
16:24 < bridge> <ryozuki> https://mitxela.com/projects/lightcomm
16:25 < bridge> <heinrich5991> I guess we can't get to xml without it feeling too long again? @learath2
16:27 < bridge> <learath2> I think it will feel too long
16:27 < bridge> <learath2> and you'll need to hack around an xml parser to get it to parse as strict xml requires a prologue and a root element
16:28 < bridge> <learath2> (or a very loose xml parser)
16:46 < bridge> <learath2> Eh, idk, is the effort worth it? We'll pretty much have to implement an xml parser of our own to support this format
16:47 < bridge> <heinrich5991> do we? I've given a pretty simple railroad diagram above, I think
16:51 < bridge> <archimede67> it does not support any nested tags other than the color tag itself if I read that correctly
16:52 < bridge> <heinrich5991> because we currently don't support any other tags. they'd get added once we add support for them
16:52 < bridge> <learath2> It does, all tags will have `text` in them, and `text` will have all tags
16:52 < bridge> <archimede67> ah okay i see
16:52 < bridge> <heinrich5991> and what @learath2 said
16:53 < bridge> <learath2> I guess if we implement it strictly like this it's not too bad
16:53 < bridge> <learath2> Yeah I'll give it a go, just a simple recursive descent parser
18:06 < bridge> <jxsl13> please add documentation for that coloration stuff once it is ready
18:24 < bridge> <learath2> 100%
20:10 < bridge> <animepdf> Where can i find ddnet database structure? prefferably as sql script. I searched thru ddnet-script and ddnet, looks like there was `sv_sql_create_tables` option before. I found script for `record_race`, `record_teamrace` and `record_maps`, but server also requires `record_points` for points stuff
20:10 < bridge> <heinrich5991> the server can create this table on its own
20:11 < bridge> <heinrich5991> https://github.com/ddnet/ddnet/blob/c532aba4e5a78d5a6fa7d58bbacc7b1a9f1ab1f2/src/engine/server/databases/connection.cpp
20:12 < bridge> <heinrich5991> (I'd suggest to let the server create the DB)
20:12 < bridge> <animepdf> That's weird, I decided to create tables myself because it wont do it, thanks, will dig into it
20:13 < bridge> <heinrich5991> try to delete all the tables and check the logs on what goes wrong with the table creation
20:25 < bridge> <animepdf> ```log

20:26 < bridge> <animepdf> nothing related to db errors
20:26 < bridge> <animepdf> besides "doesn't exist"
20:27 < bridge> <heinrich5991> ah
20:27 < bridge> <heinrich5991> apparently you need to pass an 8th parameter to the `add_sqlserver` command
20:28 < bridge> <heinrich5991> `add_sqlserver rw database prefix user password ip port setup`
20:28 < bridge> <heinrich5991> pass a `1` to the `setup` parameter
20:29 < bridge> <animepdf> oh wow, yeah that worked perfectly
20:30 < bridge> <animepdf> thanks a lot
20:30 < bridge> <heinrich5991> (probably disable it afterwards again)
20:30 < bridge> <heinrich5991> you're welcome
20:36 < bridge> <animepdf> And a little newbie linux question. I have `logfile servers/8303.log` and I get `E server: failed to open 'servers/8303.log' for logging`, I even did `chmod 777`, just in case, but just doesn't work
20:36 < bridge> <mikhuillll> download the newest version to your phone for anyone who doesn't find it difficult
20:37 < bridge> <heinrich5991> not sure where the logfile goes, probably into your config directory
20:37 < bridge> <heinrich5991> you'd need to create a `servers` folder there
20:37 < bridge> <heinrich5991> also, don't do `chmod 777`
20:38 < bridge> <animepdf> that was desperate move, will try the config dir
20:43 < bridge> <animepdf> if I have `$CURRENTDIR` in `storage.cfg`, shouldn't it look for file in relative path too?
20:44 < bridge> <heinrich5991> only for reading files, I think
20:44 < bridge> <heinrich5991> it uses the first or last entry for writing files
20:46 < bridge> <animepdf> xd, i removed userdir and datadir from storage and it used it for writing, i guess its first-only, because currentdir was last
20:46 < bridge> <heinrich5991> there you go 🙂
20:46 < bridge> <heinrich5991> I didn't remember whether it was first or last
