That you're able to add these to a list and use their interface methods
Only really used interfaces for instancing, such as being able to tell what type of data i am about to parse using instanceof
eternal osprey
oooowh so if you have an array of an interface, it can hold all types of classes IF the classes implement that interface? that makes more sense now
thank youu!
lyric mountain
yep, u can always put subclasses in the same collection in they implement the same interface/superclass
eternal osprey
ahaaa i see!
i could then for example loop over tit and use all methods on it that i defined.
rustic nova
Pog
eternal osprey
if i define a public int in the interface, it will be readable by all classes but not changeable right?
unless they make a copy?
eternal osprey
owh i see but int price = 50; for example
it would be readable but not changeable right?
rustic nova
Not in the interface, the interface is essentially a "blueprint"
Theoretically a blueprint
eternal osprey
I see, thanks once again!
rustic nova
There's something called abstract interfaces too, but tbf have never worked with these myself
So ask the java god KuuHaKu about abstract interfaces
Since abstract classes are able to do what you were mentioning
lyric mountain
interfaces can only have static constants
eternal osprey
There's something called abstract interfaces too, but tbf have never worked with...
i haven't reached that part yet so i don't think i need them for this course
lyric mountain
that means all "variables" will be final
eternal osprey
uhuh yeah! Got it, thank you!
rustic nova
Was i right with the abstract classes tho?

Made a state validator which passes state assignments and previous values to the next do/go call.
param 0 is code
param 1 is expected value
param 2 is error value [status code, text]
param 3 is key to assign to state
Helpful for things like POST form validation and protecting against Cross Site Request Forgery
sudden geyser
so like a more pieced together assert

Essentially. Although this to me is way more easy to digest and each stage depends on each other stage prior succeeding

I'm filling the form for my discord bot verification, how do I answer this question?
The only message content that my discord bot stores is the AFK reason & it's stored as long as the user doesn't send a message in chat. There's no point in deleting it after 30 days.
rustic nova
discord wants you to delete that after 30 days then

i wouldnt count that as storing message content
afk reason is specifically an option for a command, initiated by the user
what they are worried about is storing message content from people's conversations and stuff, like message backups and stuff like snipe commands

Ah I see. So storing Waifu names is also not something they'd count as storing message content I assume.
For context, users can collect cards & set names for their cards with commands which are stored inside the database

ask your question
eternal osprey
In java, i am creating a interface geometric and 2 classes that implement this geometric interface
i want to push these 2 created objects from the classes into a geometric array
where's the best place to have that array stored?
in the interface itself would be a nono, but where else?
I have a iohandler, must i put it in there then?
wheat mesa
where's the best place to have that array stored?
Huh?
Just Geometric[] would be fine would it not?
Maybe I don’t understand the question
eternal osprey
Oowh i can explain it a bit more thorough
I have 2 classes, triangle and circle.
I also have an interface Geometric that has several methods to be defined.
I want to create an array that holds all triangles and circles i want
but for that i must create an array of geometric right. Where should i put this array? Inside the gemoetric interface? Because i want to be able to access it from all classes, and modify it within the classes.
hope that i made it a bit more clear
lyric mountain
are u trying to retrieve all classes that implement Geometric?
because, like, I don't get what ur trying to do, but I think u have the wrong idea of what an interface is
rustic nova
interface: is essentially a blueprint
you cant pass values to other classes that implement that interface
you'd need an abstract interface and a static variable
not java

rustic nova
Rust has some good crates for oauth afaik though

lyric mountain
for sites I'd just use the basic html kit
that's backend, not front
they can be done separately, it's all api in the end
idk, for backend I just use java
an endpoint
oauth is nothing more than a 2-step api flow
you redirect the user to oauth
user authorizes
you receive the key
you trade the key with the server
you receive the data
you redirect the user to whatever u want
storing is just to be able to retrieve the data again without needing to ask for authorization
any language will suffice, oauth ain't as complicated as it seems
store what?
if they aren't logged in there's nothing to store
solemn latch
Oauth should handle redirects anyway.
lyric mountain
simply redirect
like, idk how to explain, all u need to do to control user flow is redirecting the request
oauth will send u whatever u need, just do your work from inside the backend
u can just redirect the user as soon as the payload arrives then finish the processing in the rest of the function
in some sense it ain't too different from handling message events in discord
eternal osprey
Beware this is just a class, not the main. I had a design question. Would it be okay to have one big helper function, or do yall recommend me to part it down? Like one for input, the other to extract parameters etc?
i always was told to make small helper functions, so i could do that here but it seems pretty useless to do that.
lyric mountain
yes you can (and should) make a helper class to keep all the commonly used methods
do note tho, u don't need to use \n in println
because println already include a linebreak
earnest phoenix
Well sometimes a double new line looks better..
sharp geyser
int a; // no initializer (default initialization)
int b = 5; // initializer after equals sign (copy initialization)
int c( 6 ); // initializer in parenthesis (direct initialization)
// List initialization methods (C++11)
int d { 7 }; // initializer in braces (direct list initialization)
int e = { 8 }; // initializer in braces after equals sign (copy list initialization)
int f {}; // initializer is empty braces (value initialization)
according to learncpp.com the first 3 are not "modern" C++ and are not really recommended under most situations, so what are the downsides compared to those 3 to the last 3?
I also don't really understand the difference between copy and direct initialization
wheat mesa
It doesn’t matter very much in the grand scheme of things
These are just different ways to initialize things
sharp geyser
So there is no downside?
lyric mountain
maybe direct allocates with the value inside while copy allocates then insert the value
regardless, compiler will use the optimal way anyway
wheat mesa
^
sharp geyser
so in grand scheme of things there is no big difference between them it just comes to a matter of preference?
@wheat mesa There is a benefit to list initilizations tho
int x {4.5} actually gives a compiler error rather then just a warning in the IDE
So if it can't safely hold the value in the type specified it will error rather than try and implicitly convert it
wheat mesa
Most people still use the generic = initializer
sharp geyser
ima use the list variant
wheat mesa
The different types of initialization become more important when working with classes and structs

general question, am i doing this right?
im running a Sanic site (sanic -> uvicorn), its forwarded ufw allow 80and shows up on the domain, everything seems fine.
But i have to run it with sudo sudo python3 main.py or else it fails to bind to port 80 (which from what i understand, is where you run HTTP webservers)
never done web/network stuff
just wanna know if thats the correct way to be doing it
im also getting this "GET /static/js/scroll.js HTTP/1.1" 304 Not Modified
no clue what that means
rustic nova
The reason why you're getting an error with binding it to port 80 is because sudo executes it with root
Anything below 1024 is a privileged port and needs root access
cloud agate
Anything below 1024 is a privileged port and needs root access
yeah thats what i was reading, so im doing that right then?
rustic nova
Yeah, especially with sudo, thats correct and normal
cloud agate
ive never ran a website before so i dont really know if i should be putting it directly on port 80
rustic nova
Port 80 is the default http port yeah
cloud agate
alr alr, so im right with forwarding 80?
rustic nova
Yup with allowing 80 through your firewall
cloud agate
also never really messed with that, all i know is you open a port up so you can access smth on a local pc
rustic nova
A port is essentially a door on which an application can talk to another application, so when your browser tries to visit yourwebsite.com, it tries to go through that door
cloud agate
yeye, thats basically all i know about it
ive been told running sanic/flask alone without wsgi or something isnt safe, uvicorn is asgi, so thats performs the same task right?
rustic nova
No clue tbf
cloud agate
again, all i know is youre supposed to run something over flask/sanic and i saw uvicorn was one of the options
rustic nova
Never worked with prod based wsgi lol
cloud agate
or something along those lines, not running a web server barebones on a domain
ah, ive just straight up never worked in any of this
super new to me, ive only done local stuff
got a friend that hosts all my stuff and gave me a subdomain so i figured i'd dip my toes in
ty for the help, from what ive gathered i think im good to call this 'production' level and leave it running so the sites accessible to everyone
rustic nova
I have like 5-6 apps running on barebone flask, never had issues
Of course it might have an impact on performance somewhat
Though never experienced it

im not really worried too much about performance, sanic is async + way faster than flask from what ive heard, so i should be good performance wise
sites super simple anyways

Eh, pastebin
lyric mountain
or can i break it down even more?
The idea isn't abt breaking, but more about reusing commonly repeated code fragments
For example, let's say u had a method to await user input that was repeated 1:1 in many places
Instead of writing it everywhere, simply make an awaitInput() method
Also, for helper methods always make them static
And the enclosing class abstract
That way you don't need to instantiate it everytime and you hint to the runtime that it'll never be instantiated
@eternal osprey
Btw u can use string format instead of concatenation
And please, make a helper method for printing
eternal osprey
owh i see, thank you!
Yup i will try to check if i have lots of functions i keep re-using and create a helper function for it
is the code okay tho, or is it fucking astrocious?
apart from the above notices
eternal osprey
And please, make a helper method for printing
wdym with this btw?
lyric mountain
public static void println(String str) {
System.out.println(str);
}
That way u can import static your.package.Helper and use println() instead of sout
eternal osprey
owh i see, thanks! I haven't covered that in the course yet but it will definitely look better!
The code right now is already a bit more broken down into smaller parts, however some methods/functions don't really get used a lot so i cannot break it down further then right?
I mean, it would be strange to have a whole method for only 1x use

why would an interface extend another interface?
Like it doesn't make sense, why don[t the classes just implement that focking interface directly instead of first extending it and hen implementing it
lyric mountain
the same reason a class extends a class
sometimes you want to add an additional methods to the interface, and usually u cant modify the original code
so waddya do? you extend it
eternal osprey
i see, so if in one interface i got the void checkoption(string x) method, and i extend that interface to another interface, in that supertype i have to put the checkoption(string x) again right?
or should i already define it in the subinterface?
and what about the classes? Should they implement the new interface as well? Or only the old (sub) interface?
lyric mountain
no
eternal osprey
sorry for all the questions, but i can't find good sources online about these questions
lyric mountain
interfaces don't (and can't) need to implement the super-interface's methods
it'll just inherit the contract
think of it like a sum
so ```java
public interface ContractA {
void doShit();
}
with ```java
public interface ContractB extends ContractA {
void doSmth();
// void doShit(); <-- inherited
}
will result in a sum of ContractA + ContractB
meaning any class that implements ContractB will automatically be implementing ContractA
sudden geyser
inherited interfaces looks suspect
lyric mountain
it's the only way to add additional clauses to interfaces if u can't modify the original code
eternal osprey
so any class implementing contractA will also be implementing the methods of contractB !
lyric mountain
no
inheritance only works one way
a class that implements ContractA doesn't implement ContractB
only the other way around
lyric mountain
so ContractB = (ContractA) theObject; will work, ContractA = (ContractB) theObject; will error
sudden geyser

take Graphics for example, it's the interface used for all java2d drawing gimmicks
for compatibility reasons, instead of changing the old interface they chose to extend it into Graphics2D
which works with every Graphics application, but contains additional methods
plus every java2d classes were changed to always use Graphics2D, but they still return as Graphics
simply because it'd break existing applications
eternal osprey
so `ContractB = (ContractA) theObject;` will work, `ContractA = (ContractB) theO...
So if i understand it correctly, the object will have type contractB ContractA ClassType (<-- ClassType if applicable)
lyric mountain
So if i understand it correctly, the object will have type contractB ContractA C...
it'll have only ContractB
sudden geyser
you still don't need an extended interface for that when you can just implement both interfaces separately
eternal osprey
Ahh yeah indeed!
lyric mountain
you still don't need an extended interface for that when you can just implement ...
you can't really
eternal osprey
Okay i understand it now, honestly inheritance is pretty cool
lyric mountain
you'd need to have twice as many methods just because you're using two separate interfaces
and that'd mean twice as much work using said framework
when extending would solve any and every compatibility issue
for example, to get a graphics2d instance u do var g2d = someImage.createGraphics()
sudden geyser
no, you'd create interface 2 while leaving interface 1 alone
so you aren't duplicating methods
lyric mountain
don't think u get the real reasoning
like, they needed to add more (and useful) methods to the Graphics interface
but doing so might break existing code (for example, implementing classes that happened to have identical method signatures)
if u implement 2 interfaces u still can't use the two at once
because one would not be translatable to the other
public class Stuff implements ContractA, ContractB {
...
}
I cannot reasonably know that every ContractA will have the methods from ContractB
meaning I'd need to check for which interfaces said class include
plus, when extending interfaces u don't need to re-type every single method, u just write the new ones
say it Hohse, no need to wait for us
create an array of that sequence and print it
quartz kindle

opaque solar

eternal osprey
kuu, you are awesome btw
sudden geyser
Take this for example:
public interface Organism {
public void create();
}
public interface Animal {
public void trick();
}
You aren't duplicating create in Animal, nor are you using extends. This leaves an interface alone to be concerned truly about itself. If you want create and trick, you say so at the signature level (at least, it should be that simple).
Breaking existing code isn't done here (nor is a concern here), plus that's more a limitation of all interface methods being required, as opposed to opt-in.
eternal osprey
honestly, just wanted to let ya know. Thanks for all the help! You saved a few hours (and fucking brain meltdown) by answering my questions
lyric mountain
Take this for example:
```java
public interface Organism {
public void create(...
public static void stuffWithAnimal(Animal a) {
a.create();
a.trick();
}
for example
you'd not be able to do this if you're using 2 interfaces (and don't which class will be supplied)
this is exactly why Graphics2D extends Graphics
you need the methods from Graphics, but also the methods from Graphics2D, and you have no idea what class will be coming from the caller
the only way that'd work (without extending) is if you replicated the methods from A to B, which would break the "single responsibility" rule
sudden geyser
oh, so java doesn't support multiple interfaces on a thing
seen this now https://stackoverflow.com/a/13261667/14695788
lyric mountain
it does allow multiple interfaces
but not extending
public class Stuff implements InterfaceA, InterfaceB, InterfaceC, InterfaceD {
...
}
but it can only have a single superclass
for generics, it can have <T extends InterfaceA & InterfaceB>
it's just looked down upon because u can't cast T to either interface
so u can't also pass it as an argument unless the function allows that exact ancestry
no wait, might've confused this part
anyway, there're reasons stated on the net, too tired to think abt it now
lament rock

by the time the async variable finishes setting, the sync variable may have been overwritten by the next time the function is called, because its global
sharp geyser
makes sense
wheat mesa
If you don’t do variable declarations anywhere else in your code I’d highly recommend changing that now
Since it can lead to mysterious bugs such as this
lyric mountain
I unironically didn't notice there was a switch-case until yall mentioned it
Please add an indent level inside cases
wheat mesa
Readability
lyric mountain
Because no indentation makes it hard to spot where the cases are
Sometimes I wonder why didn't js get the enhanced switches yet
Usually it gets qol features before other langs
hushed robin
where should i indent
lyric mountain
After the case
quartz kindle
i like doing mine like this
switch(a) {
case b: {
doC();
break;
}
}
Same
lyric mountain
It's been ages since I wrote switches like that, but I also used braces
quartz kindle
or like this if its a one liner:
switch(a) {
case b: doC(); break;
}
ye
quartz kindle
and for multi-case cases:
switch(a) {
case b: case c: {
doBorC();
break;
}
}
why use those things
{}
wheat mesa
It’s interesting that even with such a simple control flow concept as a switch case there’s so many tricks with it
lyric mountain
why use those things
Scope preservation
quartz kindle
why use those things
helps keep things visible, clear and organized
wheat mesa
But yeah that’s the idea
hushed robin
ok
sharp geyser
why use those things
more readability and lets you see the clear boundaries of the scope
damn late message

plus the good old switch true
sharp geyser
discord laggedfor me
quartz kindle
switch(true) {
case a > 10: {
...
}
}
this ?
wheat mesa
Much better
hushed robin
ok
sharp geyser
Want to experience some fun? remove those breaks 
quartz kindle
:^)
hushed robin
what would happen
hushed robin
bruh
sharp geyser
it would go through every case if it evaluates properly
lyric mountain
I like groovy switches
return switch (value) {
case { it > 10 } -> "Bigger than 10"
case String -> "Isn't even a number"
case 5 -> "Is five"
}
i believe default ts and eslint disallow switch fallthrough lmao
hushed robin
why
sharp geyser
pretty sure I could do switch fallthrough with ts
wheat mesa
Well yeah but ts is nothing more than a suggestion tbh
sharp geyser
yea
wheat mesa
You can always tell the compiler to shut up and it’ll listen
I believe up until recently (or maybe even still) C# treated falling through as a compile error
sharp geyser
Can you use switches to determine the type of something like what haku did
quartz kindle
lel
wheat mesa
There’s some tricks but I don’t believe there’s a solid way to do like switch(typeof someObj)
hushed robin
guys
lyric mountain
In java it'll be possible next version
hushed robin
what does break do outside of switch
lyric mountain
Plus auto-casting
sharp geyser
nothing I dont think
wheat mesa
Stops a loop body
sharp geyser
unless you are in a loop
wheat mesa
Probably some other stuff too but not sure about those use cases
sharp geyser
tho your IDE will probably warn you if you use break outside of the appropriate use cases
lyric mountain
The only other usage is breaking out of named loops
wheat mesa
Oh yeah
sharp geyser
named loops?
wheat mesa
Very niche
quartz kindle
switch(typeof) is a thing in js, idk about other langs
wheat mesa
switch(typeof) is a thing in js, idk about other langs
Is it?
quartz kindle
yeah?
wheat mesa
Oh well i guess typeof is just an operator that returns a string
quartz kindle
yup
wheat mesa
I forgor
quartz kindle
so break in loop = loop end
yes
wheat mesa
Was thinking more like Java where there isn’t a solid way to do it
lyric mountain
named loops?
loop:
for (int y = 0; y < height; y++) {
for (int x = 0; x < width; x++) {
if (x == 5) break loop;
...
}
}
No
quartz kindle
no
lyric mountain
Shitty example, but it'll do
quartz kindle
switch is like if-else
wheat mesa
It’s based on context
Switch statements are just syntactic sugar for if else essentially
quartz kindle
```java
loop:
for (int y = 0; y < height; y++) {
for (int x = 0; x < width; ...
obscure js things, blocks with labels
lyric mountain
Most langs have it, can also name blocks in java
wheat mesa
Basically just means a more friendly way to write something
sharp geyser
```java
loop:
for (int y = 0; y < height; y++) {
for (int x = 0; x < width; ...
I actually know about t his, didn't know it was called a named loop
hushed robin
i see
quartz kindle
thinks that make code easier to understand, but under the hood does the same thing as you would do with more complicated code
lyric mountain
I actually know about t his, didn't know it was called a named loop
U can also name blocks, but depending on the lang it'll do nothing
hushed robin
so like .some?
wheat mesa
“Syntactic sugar” usually means you can write something in one way, but the “sugar” is that you can do it in a nicer way
lyric mountain
block: {
...
}
I wonder if C++ has named loops
lyric mountain
Probably
wheat mesa
Basically every language feature over machine code could be considered syntactic sugar though by that definition I suppose 😆
lyric mountain
It's pretty useful, especially if ur doing image ops

my bot is now fully using sqlite no more discord messages database 😵💫

more or less, you could say that a array.forEach is syntatic sugar for for(const item of array) but thats not exactly true because they work differently under the hood, but for example class in js is syntatic sugar for working with prototypes, under the hood they do exactly the same thing, but classes are easier to understand and write
wait wrong reply
quartz kindle
so like .some?
i was replying to this
hushed robin
should i use for of will it really make a difference
sharp geyser
Are we just going to ignore that this guy used discord messages as a database?
hushed robin
yes
quartz kindle
yes
sharp geyser
thats more unreliable than json
hushed robin
no longer though it's now sqlite
kuuhaku recommended me better sqlite so after a day of some hard brain thoughts i switched
quartz kindle
should i use for of will it really make a difference
unless you're writing performance-sensitive code, no it wont make a difference
sharp geyser
sqlite is by far the easiest of them
hushed robin
unless you're writing performance-sensitive code, no it wont make a difference
ok im going to keep forEach
it looks prettier
hushed robin
also guys
sharp geyser
Im also pretty sure forEach is slower compared to a conventional for of loop
quartz kindle
actually, for(const item of array) itself is a syntatic sugar for for(let i = 0; i < array.length; i++) { const item = array[i] }. unlike array.forEach, those two for loops do exactly the same thing under the hood
well not actually exactly, but semantically the same thing
for(... of) will always be a bit slower
sharp geyser
in the bigger scope of things is for of faster then forEach?
quartz kindle
for..of should be roughly the same performance as array.forEach
