02:33 <+bridge> [ddnet] I cant tag you chillerbot 02:36 <+bridge> [ddnet] i think u just have to say ChillerDragon 03:33 <+bridge> [ddnet] just like in teeworlds ChillerDragon 06:39 <+bridge> [ddnet] ChillerDragon: stop irc 09:53 <+ChillerDragon> henlo @cagent 09:53 <+ChillerDragon> can we chat somewhere non here? 11:48 <+bridge> [ddnet] https://discord.gg/4BQbcq6M 12:01 <+bridge> [ddnet] lol 13:20 <+bridge> [ddnet] Question, where can i see the source of the ddnet discord bot? I just wanted to implement them on our server 13:22 <+bridge> [ddnet] nvm, i just found it 13:23 <+bridge> [ddnet] $about 13:23 <+bridge> [ddnet] the commits link to the repository 13:25 <+bridge> [ddnet] thank you! 13:26 <+bridge> [ddnet] $invite 13:26 <+bridge> [ddnet] 13:26 <+bridge> [ddnet] u can invite him btw 13:26 <+bridge> [ddnet] it* 14:57 <+ChillerDragon> oh lol ddnet code base has Config() now but its a trap xd 14:57 <+bridge> [ddnet] it's a trap? 14:57 <+ChillerDragon> im so used to 0.7 base so i just used Config() in ddnet code and its a crash 14:57 <+ChillerDragon> ye 14:57 <+ChillerDragon> its nullptr 14:57 <+ChillerDragon> dangerous 14:57 <+bridge> [ddnet] fix pls 14:57 <+ChillerDragon> u 14:58 <+bridge> [ddnet] no 14:58 <+ChillerDragon> i probably forgot to set something up 14:58 <+ChillerDragon> its in my own component 14:58 <+ChillerDragon> yea lets see if i feel motivated to dig in there 14:58 <+ChillerDragon> who did that thing again forgot the name 14:58 <+bridge> [ddnet] Kaffeine? 14:58 <+ChillerDragon> yea sounds aboutright 14:58 <+ChillerDragon> ur brain is so good 14:59 <+ChillerDragon> remember and shit 14:59 <+ChillerDragon> guess ima use g_Config for now^^ 14:59 <+ChillerDragon> also @cagnet troll 14:59 <+ChillerDragon> omg typo 15:00 <+ChillerDragon> @cagent come search me ingame tw chat is best im online all day tho mostly afk 17:12 <+bridge> [ddnet] How do I find out my DDNet version? 17:13 <+ChillerDragon> local console 17:13 <+ChillerDragon> top right 17:13 <+ChillerDragon> oh remote console also works 17:13 <+ChillerDragon> @NeXus 17:14 <+bridge> [ddnet] Ah got it ty 18:17 <+bridge> [ddnet] how many players does a server see in a day? 18:17 <+bridge> [ddnet] I still want to try my "one port per player" idea at some point 18:18 <+bridge> [ddnet] Sure, that's a nice idea, I also thought about that yesterday in the shower 😄 18:19 <+bridge> [ddnet] What was the idea behind that? 18:19 <+bridge> [ddnet] first the idea would be that the kernel can drop packets much faster than we can 18:19 <+bridge> [ddnet] so if they don't attack the main port, the kernel can drop the packets. so they'll send garbage to the main port 18:20 <+bridge> [ddnet] then we limit the amount of traffic we accept on the main port 18:20 <+bridge> [ddnet] So we drop with iptables? 18:20 <+bridge> [ddnet] resulting in no one being able to connect and no one being dropped 18:20 <+bridge> [ddnet] hopefully* 18:20 <+bridge> [ddnet] the amount of traffic on the main port? yes, iptables 18:20 <+bridge> [ddnet] On GER2: `grep "player is ready" servers/*.log* | sed -e "s/.*addr=<{$.*$:[0-9]*\}>.*/\1/" | sort | uniq | wc -l` 18:20 <+bridge> [ddnet] 9175 18:21 <+bridge> [ddnet] hm, that's a significant fraction of the /16 space we have 😦 18:21 <+bridge> [ddnet] needs to be more dynamic than once per day apparently 18:21 <+bridge> [ddnet] We don’t need it to be unique, do we? 18:22 <+bridge> [ddnet] not necessarily, but reduces thinking needed 18:23 <+bridge> [ddnet] Also I’m not very familiar with how the kernel handles traffic on different ports 18:23 <+bridge> [ddnet] I have a worrying feeling that the massive load on the main port might affect the others anyway 18:24 <+bridge> [ddnet] even if we tell the kernel to drop udp packets on the main port? 18:24 <+bridge> [ddnet] Also another performance concern I’d have is the 64 new sockets we need to care about. Though I hear epoll has fairly decent behaviour 18:24 <+bridge> [ddnet] yes, 64 new sockets, epoll might be fine 18:24 <+bridge> [ddnet] web servers handle more than 64 sockets, I think 18:25 <+bridge> [ddnet] nftables is quite close to the userspace almost on the edge of the network stack. I’m just not sure what the performance characteristics of the layers below are 18:26 <+bridge> [ddnet] That one cloudflare blog where they were trying to drop as fast as possible, they got a huuge increase going from dropping in nftables to dropping on the NIC with a BPF filter 18:27 <+bridge> [ddnet] I mean we can manage a BPF filter as well 😉 18:27 <+bridge> [ddnet] if we get access to state that lets us track how much we already saw this second 18:27 <+bridge> [ddnet] There is significant work being done in the kernel is what I mean, but yeah I think it might be worth a test 18:27 <+bridge> [ddnet] My master thesis is about ebpf 18:27 <+bridge> [ddnet] @TsFreddie to the rescue 18:28 <+bridge> [ddnet] And I still have no idea how bpf filters work 18:28 <+bridge> [ddnet] Nooooooo 18:28 <+bridge> [ddnet] @heinrich5991 I guess this will be a breaking network change tho 18:28 <+bridge> [ddnet] I can probably write ebpf programs. And I know there's a bpf syscall but that's all I know tbh 18:28 <+bridge> [ddnet] not breaking 18:29 <+bridge> [ddnet] "not breaking" 18:29 <+bridge> [ddnet] only breaking for those on the old protocol during DoS 18:29 <+bridge> [ddnet] More backwards compat code on the server? ;P 18:29 <+bridge> [ddnet] ye 18:30 <+bridge> [ddnet] Which protocol is the "old protocol" 18:30 <+bridge> [ddnet] So I guess we establish a traditional tw connection on the main port, the client sends something like STARTTLS or FTP PASV. We give them a port to contact us on and we kill the connection? 18:30 <+bridge> [ddnet] yes 18:31 <+bridge> [ddnet] I’d be concerned about an attack trying to occupy all ports on the server 18:31 <+bridge> [ddnet] hm? 18:31 <+bridge> [ddnet] we allow 64 players per server 18:32 <+bridge> [ddnet] Yes, but if people try to connect, we can’t reserve them a slot. As that gives the old (connecting) attack 18:32 <+bridge> [ddnet] apparently we need to verify their IP address before giving them another port 18:33 <+bridge> [ddnet] I guess the handshake we have rn is enough for that? 18:33 <+bridge> [ddnet] yes 18:33 <+bridge> [ddnet] but the handshake in its current form is brittle and should be changed at the next opportunity 18:33 <+bridge> [ddnet] one lost packet and you're stuck forever 18:33 <+bridge> [ddnet] (the third packet specifically) 18:34 <+bridge> [ddnet] The only concern that remains is a non spoofed attack that just keeps asking for a new port, but I guess we can mitigate that with a hashmap of ip:clientport to serverport and never give a new one and limit ports per ip 18:35 <+bridge> [ddnet] Sounds like a solid idea to me, lmk if you ever decide to implement it 😄 18:35 <+bridge> [ddnet] last time you weren't that sold on the idea, but I also haven't implemented it since last time 😛 18:35 <+bridge> [ddnet] so "some day, maybe" 18:36 <+bridge> [ddnet] I don’t remember my concern back then 18:36 <+bridge> [ddnet] But I was fairly convinced it wouldn’t work so I wonder what my argument was ;P 18:37 <+bridge> [ddnet] who would ddos ddnet anyway 18:37 <+bridge> [ddnet] doesn't really matter, it happens 18:37 <+bridge> [ddnet] is it always SP | Someone 18:37 <+bridge> [ddnet] please don't discuss specific DoSers, that's basically what they're after 😉 18:38 <+bridge> [ddnet] he donates ddnet btw 18:38 <+bridge> [ddnet] Yeah, he's not an attacker, just a troll 18:38 <+bridge> [ddnet] is he even in this disc? 18:38 <+bridge> [ddnet] no 18:38 <+bridge> [ddnet] but 18:38 <+bridge> [ddnet] who knows :troll: 18:39 <+bridge> [ddnet] Just looked up some xdpfilter 18:40 <+bridge> [ddnet] Feel like magic 18:40 <+bridge> [ddnet] Xdp is the pinnacle of filtering 18:40 <+bridge> [ddnet] Filtering packets at the lowest possible level 18:42 <+bridge> [ddnet] NICs with offloaded xdp are genius 18:48 <+bridge> [ddnet] https://github.com/zoidbergwill/awesome-ebpf 19:02 <+bridge> [ddnet] my supervisor wants me to process data with ebpf on nvme controller. 19:02 <+bridge> [ddnet] 19:04 <+bridge> [ddnet] Why I can just download map so fucking slowly on my srv? 19:04 <+bridge> [ddnet] Needs like 20 sec 19:04 <+bridge> [ddnet] ddnet? vanilla? 0.6? 0.7? 19:04 <+bridge> [ddnet] ddnet 19:04 <+bridge> [ddnet] client is 0.6 or 0.7? 19:04 <+bridge> [ddnet] 0.6 19:04 <+bridge> [ddnet] ddnet or vanilla 0.6? 😄 19:05 <+bridge> [ddnet] Its not just me, there is something on my srv i guess 19:05 <+bridge> [ddnet] If it's ddnet client your map is just massive 19:05 <+bridge> [ddnet] the udp fast download can only do so much, ddnet servers use http downloads to get around that 19:06 <+bridge> [ddnet] probs a custom server 19:06 <+bridge> [ddnet] (custom map) 19:06 <+bridge> [ddnet] I think @deen did add a couple maps that are played a lot to the map server 19:07 <+bridge> [ddnet] Anyway, if the map is on maps.ddnet.tw people should get http downloads 19:07 <+bridge> [ddnet] http download is really unstable in china btw. Many players got stuck at connecting. 19:07 <+bridge> [ddnet] Yeah needs a CDN for china 😛 19:08 <+bridge> [ddnet] Oof 19:08 <+bridge> [ddnet] @Marius u can try 19:08 <+bridge> [ddnet] sv_fast_download 1 19:08 <+bridge> [ddnet] sv_high_bandwidth 1 19:08 <+bridge> [ddnet] Is there a way to fallback to udp download a bit faster. 19:08 <+bridge> [ddnet] but if the http download times out it should fall back to udp automatically 19:09 <+bridge> [ddnet] But it takes awhile to timeout http 19:09 <+bridge> [ddnet] Already both on @Jupstar ✪ 19:09 <+bridge> [ddnet] I'm sure there is a http timeout config somewhere, but that might create issues with ddnet-info.json 19:09 <+bridge> [ddnet] mhh with SDL 2.0.14 i cannot minize the client anymore... very annoying 19:09 <+bridge> [ddnet] why must this lib always be buggy <.< 19:09 <+bridge> [ddnet] @Marius what is your m_SvMapWindow 19:10 <+bridge> [ddnet] sv_map_window * 19:10 <+bridge> [ddnet] Like can we fallback to udp download a bit earlier and if the http went through just drop the downloaded udp data. 19:10 <+bridge> [ddnet] 15 19:10 <+bridge> [ddnet] @TsFreddie smells like a great way to have race conditions 😛 19:10 <+bridge> [ddnet] ye 19:11 <+bridge> [ddnet] @Marius you can go up to 100, but raise it slowly, too high and more people will have to fall back to slower download 19:11 <+bridge> [ddnet] But we do have a tutorial for straight up turning the setting off in our chat so it's not really a big deal. 19:13 <+bridge> [ddnet] I wonder if we can get a mirror of the map db in china 19:13 <+bridge> [ddnet] Actually. If http timeout are we still trying http on next connection 19:13 <+bridge> [ddnet] Can we fallback to udp until they restart the game. 19:13 <+bridge> [ddnet] @TsFreddie yes because I think the saner assumption is that we broke the server or it's overwhelmed for a sec and it'll be back 19:14 <+bridge> [ddnet] Would be great for china, not sure how good it'd be for everyone else though 19:14 <+bridge> [ddnet] How is it failing? Does the download even start? 19:14 <+bridge> [ddnet] I don't think so 19:14 <+bridge> [ddnet] Most ppl just say they are stuck at connecting 19:15 <+bridge> [ddnet] next time it happens try to get us a console/log pls 19:15 <+bridge> [ddnet] Sure 19:16 <+bridge> [ddnet] I got pretty good connection to ddnet.tw at home so might be difficult to come by myself 19:17 <+bridge> [ddnet] Wait. I might turned http download off ages ago maybe that why I think I have pretty good connection 19:17 <+bridge> [ddnet] I'll check tomorrow I guess 19:19 <+bridge> [ddnet] maybe we can get a server in china to host the maps, tho we'd need to host BIND to send people from china a different ip 19:19 <+bridge> [ddnet] Are ddnet.tw CDNed 19:20 <+bridge> [ddnet] Is* 19:20 <+bridge> [ddnet] nope 19:20 <+bridge> [ddnet] I think even a South Korea mirror might be worth it 19:22 <+bridge> [ddnet] Mainland bandwidth is so limited and probably it'd be better off covering the east instead of only china I guess? 19:23 <+bridge> [ddnet] The location we could discuss, I'd guess the larger issue is actually setting up BIND and stuff 😛 19:23 <+bridge> [ddnet] We don't host dns now 19:23 <+bridge> [ddnet] 19:23 <+bridge> [ddnet] right 19:23 <+bridge> [ddnet] Can server hint which map mirror client should use 19:24 <+bridge> [ddnet] Like why would one want to use a Asian mirror when connecting to GER. 19:25 <+bridge> [ddnet] :doge: 19:26 <+bridge> [ddnet] Actually, why do we even need it to be automatic? 19:26 <+bridge> [ddnet] Also probably enables mods for hosting their own http map database 19:26 <+bridge> [ddnet] You could host a mirror in china and just tell people to change their `cl_map_download_url` 19:26 <+bridge> [ddnet] 19:28 <+bridge> [ddnet] I mean I could just tell them to turn off http download. it is not that slow on chn servers and they don't seems to venture out for other servers (yet) 19:28 <+bridge> [ddnet] I think the issue is I can't tell everyone to change 19:28 <+bridge> [ddnet] Huh, the udp downloads are soo slow 19:29 <+bridge> [ddnet] I guess you got used to it there 19:29 <+bridge> [ddnet] Ye 19:30 <+bridge> [ddnet] Funny story, I ordered ziploc bags and they shipped them in a larger ziploc bag 19:30 <+bridge> [ddnet] If it is at least semi automatic, I don't need to paste the solution every time someone have the same problem. Plus there are lots of players who just don't care about joining a community 19:30 <+bridge> [ddnet] I’ll look into BIND for you 19:31 <+bridge> [ddnet] Maybe it’s not as PITA as I remember ;P 19:31 <+bridge> [ddnet] Maybe look into letting the server decide the URL as well. Maybe it is easier idk 19:33 <+bridge> [ddnet] There are security implications of that which I’m not really sure I want to think about right now 😉 19:33 <+bridge> [ddnet] 19:33 <+bridge> [ddnet] Right. 19:34 <+bridge> [ddnet] Triggering AV for starter I guess 19:35 <+bridge> [ddnet] I'll see if we have cheaper way to host files in the meantime 19:36 <+bridge> [ddnet] @Learath2 I think GET requests should mostly be fine 19:37 <+bridge> [ddnet] hmmmmm 19:37 <+bridge> [ddnet] you don't only get a GET request but also if they match a certain SHA256 19:37 <+bridge> [ddnet] that might be less fine 19:57 <+bridge> [ddnet] jump_amount How many jumps you have 2 (default) 19:57 <+bridge> [ddnet] for tune zone 20:09 <+bridge> [ddnet] someone that codes please 20:09 <+bridge> [ddnet] explain me how the fuck lambdas work 20:09 <+bridge> [ddnet] Task.Run(() => CarregarDataAtual()); 20:09 <+bridge> [ddnet] ```Task.Run(() => CarregarDataAtual());``` 20:09 <+bridge> [ddnet] which language is that? it looks like it tells the language to run CarregarDataAtual() at some later point in time 20:09 <+bridge> [ddnet] c# 20:10 <+bridge> [ddnet] CarregarDataAtual is LoadActualDate() 20:10 <+bridge> [ddnet] CarregarDataAtual() is LoadActualDate() 20:10 <+bridge> [ddnet] CarregarDataAtual() is LoadActualDate() (english translation) 20:10 <+bridge> [ddnet] https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task.run?view=net-5.0#System_Threading_Tasks_Task_Run_System_Action_ 20:10 <+bridge> [ddnet] Queues the specified work to run on the thread pool and returns a Task object that represents that work. 20:10 <+bridge> [ddnet] Ik task.run does that, but the lambda 20:10 <+bridge> [ddnet] i.e. it tells C# to run the function CarregarDataAtual() at some later time 20:11 <+bridge> [ddnet] I dont underrstand the lambda ;_; 20:11 <+bridge> [ddnet] I dont understand the lambda ;_; 20:11 <+bridge> [ddnet] the lambda is the function that is called at a later time 20:11 <+bridge> [ddnet] e.g. if you have a function 20:11 <+bridge> [ddnet] ```c# 20:12 <+bridge> [ddnet] public static int Return7() { 20:12 <+bridge> [ddnet] return 7; 20:12 <+bridge> [ddnet] } 20:12 <+bridge> [ddnet] ``` 20:12 <+bridge> [ddnet] e.g. if you have a function 20:12 <+bridge> [ddnet] ```c 20:12 <+bridge> [ddnet] public static int Return7() { 20:12 <+bridge> [ddnet] return 7; 20:12 <+bridge> [ddnet] } 20:12 <+bridge> [ddnet] ``` 20:12 <+bridge> [ddnet] that's the same as a lambda `() => 7` 20:13 <+bridge> [ddnet] a lambda is a shorter way to define a function 20:33 <+bridge> [ddnet] Are u catalan? 20:34 <+bridge> [ddnet] :poggers: 20:36 <+bridge> [ddnet] Catalunya no existe ql 20:36 <+bridge> [ddnet] Ql weon 20:37 <+bridge> [ddnet] @Ryozuki im brazillian 20:37 <+bridge> [ddnet] Ah ok 20:37 <+bridge> [ddnet] Ot looked so similar 20:37 <+bridge> [ddnet] oh @heinrich5991 thansk 20:37 <+bridge> [ddnet] In catalan it would be CarregarDataActual() 20:37 <+bridge> [ddnet] oh 20:38 <+bridge> [ddnet] its spanish,franchise and italian native 20:38 <+bridge> [ddnet] that's why 20:38 <+bridge> [ddnet] portuguese ± spanish 20:39 <+bridge> [ddnet] It has similarities but it's not the same 20:39 <+bridge> [ddnet] As in other languages 20:39 <+bridge> [ddnet] Linguistics time 20:39 <+bridge> [ddnet] yeah its similar 20:39 <+bridge> [ddnet] 🇫🇷🇮🇹🇪🇸 20:40 <+bridge> [ddnet] Ew 20:40 <+bridge> [ddnet] If i had nitroll 20:40 <+bridge> [ddnet] Someone put the catalan one 20:40 <+bridge> [ddnet] :trollet: 20:40 <+bridge> [ddnet] 20:40 <+bridge> [ddnet] ```Func square = x => x * x; 20:40 <+bridge> [ddnet] Console.WriteLine(square(5)); 20:40 <+bridge> [ddnet] // Output: 20:40 <+bridge> [ddnet] // 25``` 20:40 <+bridge> [ddnet] yes 🙂 20:40 <+bridge> [ddnet] Lambdas are fun 20:41 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/803348773190500352/unknown.png 20:41 <+bridge> [ddnet] o 20:41 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/803348902605750302/Screenshot_20210125-154128_Discord.jpg 20:41 <+bridge> [ddnet] It doesn't exist 20:41 <+bridge> [ddnet] Its called flag_spain on some servers 20:42 <+bridge> [ddnet] I think its in fng sv 20:42 <+bridge> [ddnet] oh god 20:42 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/803349034688446494/unknown.png 20:42 <+bridge> [ddnet] :flag_spain: 20:42 <+bridge> [ddnet] :justatest: 20:42 <+bridge> [ddnet] my brain slow 20:42 <+bridge> [ddnet] @heinrich5991 i like that rust has FnOnce for functions meant to be called 1 time only 20:42 <+bridge> [ddnet] :bluekitty: 20:44 <+bridge> [ddnet] Its not rly the catalan flag tho, its the catalan flag for independence 20:48 <+bridge> [ddnet] there is no catalan flag because it doesnt exist 21:00 <+bridge> [ddnet] :kek: :kek: :kek: 21:13 <+bridge> [ddnet] my code is a mess but im lazy to fix it 21:17 <+ChillerDragon> relatable 21:17 <+ChillerDragon> did u try using shell instead of C# ?

21:23 <+Ryozuki> what is that code even 21:23 <+ChillerDragon> xd 21:23 <+Ryozuki> i guess its just troll 21:23 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/803359382414950430/unknown.png 21:23 <+bridge> [ddnet] best part 21:23 <+ChillerDragon> xd 21:23 <+ChillerDragon> where it all comes together 21:23 <+Ryozuki> is it generated by some script 21:23 <+Ryozuki> how can u maintain this 21:23 <+bridge> [ddnet] lemme try compiling it 21:23 <+ChillerDragon> its handwritten 21:24 <+ChillerDragon> Ryozuki: i did not know better back then 21:24 <+Ryozuki> u have a lot of time in ur hands 21:24 <+ChillerDragon> not enough time to learn to code tho 21:24 <+bridge> [ddnet] nvm rider will take long to make another null project 21:24 <+ChillerDragon> so i just started with what i knew 21:24 <+Ryozuki> ChillerDragon well u waste ur time doing this stuff 21:24 <+Ryozuki> no wonderu dont have time to learn actual code 21:24 <+Ryozuki> xd 21:24 <+ChillerDragon> xd 21:24 <+ChillerDragon> i had big fun 21:24 <+Ryozuki> to me it looks like hell 21:24 <+Ryozuki> how is this fun xd 21:24 <+ChillerDragon> i was watching this 5 min yt video 21:24 <+ChillerDragon> he explained what a srting is 21:25 <+ChillerDragon> and a if statement 21:25 <+ChillerDragon> and how to hello world 21:25 <+ChillerDragon> and i was like nice ima build a game with this 21:25 <+Ryozuki> u should save this 21:25 <+Ryozuki> its art 21:25 <+ChillerDragon> its saved 21:25 <+ChillerDragon> i tried to rewrite in rust 21:25 <+ChillerDragon> 3 times 21:25 <+ChillerDragon> and gave up 21:25 <+ChillerDragon> cuz rust so hard 21:25 <+Ryozuki> lmao 21:26 <+Ryozuki> i think its hard cuz its hard to know what this code does 21:26 <+bridge> [ddnet] debugging async scripts is annoying 21:26 <+ChillerDragon> even assembly is easier https://raw.githubusercontent.com/chidraqul/chidraqul10/master/chidraqul10.asm 21:26 <+bridge> [ddnet] debugging async code is annoying 21:26 <+Ryozuki> i would learn more asm but im 2 lazy to learn the register names 21:27 <+ChillerDragon> use comments 21:27 <+Ryozuki> nice table u got there tho 21:27 <+ChillerDragon> :D 21:27 <+Ryozuki> ; +-----------------------------------+ 21:27 <+ChillerDragon> ye also needed em register names 21:27 <+Ryozuki> ; | 8-bit | 16-bit | 32-bit | 64-bit | 21:27 <+Ryozuki> ; +--------+--------+--------+--------+ 21:27 <+Ryozuki> ; | al | ax | eax | rax | 21:27 <+Ryozuki> ; | bl | bx | ebx | rbx | 21:27 <+Ryozuki> ; | cl | cx | ecx | rcx | 21:27 <+Ryozuki> ; | dl | dx | edx | rdx | 21:27 <+Ryozuki> ; | sil | si | esi | rsi | 21:27 <+Ryozuki> ; | dil | di | edi | rdi | 21:27 <+Ryozuki> ; | bpl | bi | ebp | rbp | 21:27 <+Ryozuki> ; | spl | sp | esp | rsp | 21:27 <+Ryozuki> ; | r8b | r8w | r8d | r8 | 21:27 <+Ryozuki> ; | r9b | r9w | r9d | r9 | 21:27 <+Ryozuki> ; | r10b | r10w | r10d | r10 | 21:27 <+Ryozuki> ; | r11b | r11w | r11d | r11 | 21:27 <+Ryozuki> ; | r12b | r12w | r12d | r12 | 21:27 <+Ryozuki> ; | r13b | r13w | r13d | r13 | 21:27 <+Ryozuki> ; | r14b | r14w | r14d | r14 | 21:27 <+Ryozuki> ; | r15b | r15w | r15d | r15 | 21:27 <+Ryozuki> ; +--------+--------+--------+--------+ 21:27 <+Ryozuki> epic 21:27 <+Ryozuki> discord didnt send it all 21:27 <+Ryozuki> lmao 21:27 <+Ryozuki> oh its doing it now 21:27 <+ChillerDragon> rip 21:28 <+Ryozuki> looks scuffed 21:28 <+Ryozuki> monospace terminal ftw 21:28 <+bridge> [ddnet] i fear assembly 21:28 <+ChillerDragon> im sure it looks fine in the only usuable discord client 21:28 <+ChillerDragon> cordless 21:28 <+ChillerDragon> i think it was also handwritten table Ryozuki xd 21:28 <+Ryozuki> ChillerDragon is the assembly game the same as the cs game? 21:28 <+ChillerDragon> i cant remember a single thing tho 21:29 <+Ryozuki> the assembly looks clean af 21:29 <+ChillerDragon> yea same functionality 21:29 <+ChillerDragon> feature complete 21:29 <+Ryozuki> nice 21:29 <+ChillerDragon> no joke :D the cs game is far more complex 21:29 <+ChillerDragon> the asm is not even working prototype 21:29 <+bridge> [ddnet] guys I think im dumb 21:29 <+Ryozuki> ah 21:29 <+Ryozuki> u troll 21:29 <+ChillerDragon> hehe 21:29 <+bridge> [ddnet] im loading 2k results from a mysql database and getting the last with Linq 21:29 <+bridge> [ddnet] is this good 21:29 <+ChillerDragon> yea i think the asm only had keypresses 21:29 <+Ryozuki> why load 2k then 21:30 <+ChillerDragon> 2k? 21:30 <+Ryozuki> just load the last 21:30 <+ChillerDragon> wat 21:30 <+bridge> [ddnet] yeah 21:30 <+bridge> [ddnet] im dumb 21:30 <+bridge> [ddnet] almost 2k** 21:30 <+bridge> [ddnet] https://cdn.discordapp.com/attachments/293493549758939136/803361258325278720/unknown.png 21:30 <+bridge> [ddnet] 1644 21:31 <+bridge> [ddnet] that's still a lot 21:31 <+Ryozuki> idk what u doing, but if u only need 1 result, u filter, order and limit 21:32 <+bridge> [ddnet] ```SELECT * 21:32 <+bridge> [ddnet] FROM table_name 21:32 <+bridge> [ddnet] ORDER BY id DESC 21:32 <+bridge> [ddnet] LIMIT 1``` 21:35 <+bridge> [ddnet] k done I guess 21:36 <+bridge> [ddnet] any C++ language expert here?
