<ChillerDragon> but whatsapp gets access to people in your contact book that did not agree to anything whatsapp related. So that is you violating the gdpr unless you asked all your friends if you can share their contact details with whatsapp.

<ChillerDragon> My laptop wasn't booting anymore and i did some stuff to make it boot again. I think that was also using the older kernel. But now apt update and install always compiles the nvidia patches and then fails.

heinrich5991 2024-05-02 05:55:04Z
(as for whatsapp being GDPR-compliant, that hinges on a probably illegal treaty between the US and the EU, the first one was called "international safe harbor privacy principles", but was successfully challenged by max schrems and declared illegal in 2015. they then put up the next treaty called "privacy shield", which was declared illegal in 2020. then they just put up the next treaty "data privacy framework", which is likely illegal, too, but yet has to be declared as such by the ecj)

Avolicious 2024-05-02 08:36:41Z
If you want to troubleshoot where the problem occurs, you have to diagnose the network at each turnpoint - done via traceroute. Just pinging a server is mostly used to check if the server is alive 🙂 But it doesnt give you a hint where its slowed down. So why traceroute? If a hoster has multiple peerings/upstreams, they can choose where your package should be coming from ( Border-Gateway-Protocol ( BGP ), is used for this task ).

I still can't quite wrap my head around the fact that we are merging a +6k -200 patch to add support for a dead fork. At least the patch seems to mostly be contained within conditionals that we'll never realistically get to remove but atleast can be folded out of the way

for example

now you can use them on ur own libs

tbf they already had them before
Avatar
Ryozuki 2024-05-02 13:22:06Z
but i think it was std only
13:22
Rust now supports a #[diagnostic] attribute namespace to influence compiler error messages. These are treated as hints which the compiler is not required to use, and it is also not an error to provide a diagnostic that the compiler doesn't recognize. This flexibility allows source code to provide diagnostics even when they're not supported by all compilers, whether those are different versions or entirely different implementations.
13:22
also the debug unsafe assert preconditions
13:22
seems nice
13:23
they also did impl Read for &Stdin

but havent tried it to know how it looks
Avatar
heinrich5991 2024-05-02 13:25:26Z
yea, debug unsafe assert preconditions seem nice
13:25
however I saw it leading to not using these functions anymore inside std
13:25
because "slow"

sounds bad if you don't even use these functions yourselves

  • Have a ping command to measure response time from discord user's pc to bot
  • Have whatever server is hosting the bot ping the ddnet server
  • Use Pythagorean theorem to get an approximate ping value for discord user's pc to ddnet server

how? you need the discord client to run your program to work
Avatar
Sans 2024-05-02 14:35:52Z
when the user runs a ping command or similar, the bot takes the timestamp of the user's message, sends a new message, and then subtracts the first timestamp from the new message timestamp, and edits that message to display the response time
14:36
it's the most accurate approximation i can do with djs
14:36
idk if there's a better way
Avatar
zhn 2024-05-02 14:38:11Z
but still user doesn't communicate with your bot directly, they do it via discord servers

you actually measure response time between you discord server and user

@Patiga if i might suggest you smth for your lib: https://docs.rs/virtual-fs/0.11.3/virtual_fs/ https://docs.rs/virtual-fs/0.11.3/virtual_fs/struct.ScopedDirectoryFileSystem.html it's not really documented and some decisions are a bit weird, but wasmer uses it for their WASI isolation. I use it now, works quite well
