Unlike other shading languages, Vcc aims to stick closely to standard C/C++ languages and merely adds a few new intrinsics to cover GPU features.

I just mentioned that self rolled file formats also work and they even work in bigger tw scale. They might be worth the trade off. If you do not need to run complex queries or join tables and similar. Just have some level/xp/points and simple ranks files work fine. And they do not require complex external libraries. 15:10 < bridge> so one account per line and it is space seperated? What if the values contain spaces? Do you disallow spaces in passwords? Do you escape spaces somehow? 15:52 < bridge> since you surely don't save passwords unhashed, spaces are no problem 15:53 < bridge> sqlite offers a couple of things for free that you don't get with plain files 15:53 < bridge> e.g. crash safety 15:53 < bridge> the data is still there, even if you were in the middle of overwriting it 15:54 < bridge> for your hand-rolled file format, that's harder to guarantee 16:06 < bridge> ACID 16:07 < bridge> https://en.wikipedia.org/wiki/ACID 17:05 < bridge> lmao the trolling 17:06 < bridge> Yea that’s nice. But not needed for all small tw mods 17:12 < bridge> you don't need the data in small tw mods? 17:12 < bridge> seems like a problem that could occur there 17:12 < bridge> a player tries to log out, the server crashes while writing their money value, the player is sad that they lost their account and their stats 17:16 < bridge> Can someone unban me on the brazilian mod map 17:19 < ChillerDragon> @heinrich5991 yes can happen but does not have to. Not sure if noby in years of running file based stats had that issue ever. I know fokko did not run into that issue. And using this statistically valuable data i can say its worth a shot for mamad to not spend 30 minutes understanding sql if he intends to rewrite the whole mod soon anyways. 17:20 < ChillerDragon> imo self rolled file stats have a bad rap. Using git backups and write to other file and copy on finish and lock files you can get something you fully understand and easy to setup that should not result in complete data loss. 17:21 < bridge> sounds like you're partially emulating sqlite 17:21 < ChillerDragon> i never visited a single db lecture in uni idk how real databases do anything 17:22 < bridge> sqlite is basically a "file based solution" that you're trying to do 17:22 < ChillerDragon> for my tw mods sql also worked better. I did some file based fng mod once and I had some bug in the locking mechanism. 17:23 < ChillerDragon> But I would not recommend new coders to mess with sql for their first mod. Might cause rage quits and have less learnings. 17:23 < ChillerDragon> Or at least mention file based is also an option 17:24 < ChillerDragon> @heinrich5991 i had to actually giggle a bit on your hashing comment i can not tell if you were trying to be funny or not xd 17:24 < ChillerDragon> i think he even said the passwords should be short so he can read them better xD 17:25 < bridge> Doing the “file based solution” properly is far harder than you make it out to be. It only appears so simple because you ignore much of the possible issues 😄 17:25 < bridge> If nothing ever goes wrong, yes, the file based solution is trivial and works well 17:25 < ChillerDragon> > 17:08:32 bridge | mamad_melanin: i just wanna look at them in a text file, each of them looking good, not to long 17:27 < ChillerDragon> > 15:52:58 bridge | heinrich5991: since you surely don't save passwords unhashed, spaces are no problem 17:27 < ChillerDragon> comedy gold 17:28 < ChillerDragon> @learath2 yea im saying that nothing actually did go wrong as far as i know 17:28 < bridge> I remember stuff going wrong for whatever reason 17:28 < bridge> was it in ddnet's file time score? 17:28 < bridge> or some random city mod? 17:28 < bridge> maybe I'm even misremembering 17:28 < ChillerDragon> ddnet file score did have some wonkeyyness here and there for sure 17:29 < bridge> I am serious about the fact that you should save passwords hashed 17:29 < bridge> then all the character set issues go away, too 17:29 < bridge> win-win 17:29 < ChillerDragon> Okay does not make it less funny 17:34 < bridge> Usernames 😬 17:35 < bridge> chillerdragon: when SQL to bash commands compiler 17:35 < bridge> passwords needing to adhere to some limited character set does not pass my security smell test 17:35 < bridge> usernames doing the same is fine IMO 17:36 < bridge> but yea, need to do that if you don't want to have a `\nPassword: 123\nMoney: 10000000\n` as username 17:36 < bridge> That is true. But it's a common source of bugs, especially if you are rolling your own 17:36 < bridge> but yea, need to do that if you don't want to have a `abc\nPassword: 123\nMoney: 10000000\n` as username 17:36 < bridge> that's not your money for a long time 😏 17:39 < bridge> https://www.phoronix.net/image.php?id=2023&image=kde_6_alpha 17:39 < bridge> epic 17:39 < bridge> the 3d cube is back 17:40 < bridge> plasma 6 gonna hit different 17:40 < bridge> sounds like 2005 linux 😄 17:40 < bridge> this time with AR? 😛 17:40 < bridge> what is ar 17:40 < bridge> i am young 17:40 < bridge> i wasnt alive in 2005 17:40 < bridge> ok maybe i was 17:41 < bridge> but learath wasnt 17:41 < bridge> learath2 isn't <20 years old IIRC 17:41 < bridge> he is so 12 17:43 < bridge> https://reversing.info/posts/guardedregions/ wuw 17:43 < bridge> There is this ongoing meme that I am 12 17:43 < bridge> ah augmented reality yeah i remember 17:43 < bridge> why meme 17:44 < bridge> It's only one of my ages.
