Just don’t be bad
proper gale
yea, same applies to the other languages.
main difference, i can tell where shit end
vast echo
Python is the best scripting language
proper gale
@vast echo not in all circumstances
vast echo
Obviously there’s no best for all use cases language
But python is my go to at work for just about anything from data processing to API calls
proper gale
see, and i use C++ if i can because once compiled it requires no runtime that isn't always installed, so it can just be run.
yes, i use C++ for scripting
vast echo
Python is better for cross platform though
proper gale
ok, then i compile my C++ for that other platform, then it needs to runtime there.
besides that basically anything on windows is a dick
but at least you only need to deal with that dick to make the script with C++, where as with python you need it to run the damn thing.
vast echo
ya thats true
I have the luxury of rarely needing to use windows
and everything I use comes with python preinstalled
so even if I make something for someone else, I dont need to install python on their machine
proper gale
yea, im not actually saying that python is bad, i do use it myself, just that its not the best.
its actually really bad in a lot of ways that can really matter.

Whats up
dim shard
so Im in Comp Sc 1 and im going ahead of the teacher bc she sucks
and I learned arrays and i was wondering how to put these 2 variables that are in a for loop and put them into one?
heres the java file
queen zenith
Alright gimme a minute
dim shard
its the two in the second for loop
queen zenith
Alright so first you cant declare variables inside of a loop
queen zenith
Because every time the loop executes the jdk tries to create an extra space in memory for the variable
if the loop runs 10 times it will try to make 10 priceForTopPicks variables
dim shard
ok
queen zenith
declare the variable outside of the loop then manipulate it within
dim shard
but if i do that then i cant use it like i wanted to
queen zenith
What is the program attempting to do
dim shard
ok so when i put the 2 variables out side of either loop it says that the variable i cant be resovled to a variable
dim shard
hold on ill be back

@last ingot thats not what i was arguing, it was more ease of running it.
also, there is a reason i dont write my C++ all that cross compatible.

@last ingot how you like my version
grades = {90:"A",80:"B",70:"C",60:"D"}
score = next((grades[item] for item in grades.keys() if result >= item),"F")
worthy dirge
how do you like my version ```C++
vector<pair<unsigned, char>>grade{ {90,'A'},{80,'B'},{70,'C'},{60,'D'} };
unsigned score;
cin >> score;
cout << (score>=60? ((find_if(grade.begin(), grade.end(), [score](pair<unsigned, char>& a) {return score >= a.first; }))->second) : 'F');
If I saw that in a code review I would reject it
Prefer clarity over cleverness
Could just break that into four lines with clearly named const bools
Const bool scoreIsFail equals.... If scoreIsFail...and so on
The compiler can and will optimize it for you
hazy summit
Thanks @last ingot , yours seems much easier to understand.

Prefer clarity over cleverness
This lol, so many people disregard the importance of readability
A lot of code (especially python, and really any other strictly dynamically-typed languages) out there that need to be hit over the head with a style guide and conventions.

I suppose there is a strong argument for complex or even hacky code in instances where it is:
- Very well documented
- Hides complexity elsewhere
- Improves performance in something that is performance critical

I have some matrices to loop through using iterators. I know they are the same size but different types. I can't declare iterators in the first statement of a for loop so I have to write them outside, messing up my local names

Hello?

Nah

With?
cursive plume
HTML & CSS possibly javascript
pulsar bough
And more specifically ?
pulsar bough
and?
pulsar bough
Wheres the question?
cursive plume
updated it
pulsar bough
Oh
cursive plume
realized it was some bad explaning
pulsar bough
I assume you could make it not display until a button is clicked
pulsar bough
Like have this.parentElement.style.display='none'; on a element in the div that is the callout
cursive plume
im a bit bad at this, your gonna have to eloborate
pulsar bough
When you define the callout have it hide it (style.display to none) then when the button is pressed unhide it
I don't really remeber js
its been a while
so just look up style.display in js, and triggering js when the element is loaded
pulsar bough
document.getElementsByClassName("callout");
use something like that to get the element
cursive plume
is see thats javascript, but im gona put that inside a <script> and then?
pulsar bough
then on button click do something like document.getElementsByClassName("callout").style.display='inline';
put that in a <onclick>
on the button
and I assume you can do something like that inside a <script> , just setting it to 'none' instead, so when it starts it will be hidden
pulsar bough
O yea
that makes more sense
as I said im kinda rusty
just use css to make it hidden and the button to make it visible
cursive plume
yeah
yeah but then im stuck in this problem how can i change it to block
when its clicked
pulsar bough
what? @cursive plume
pulsar bough
why block?
cursive plume
<button class='button1' onclick="displayToggle1('callout')">Example</button>
like that?
@pulsar bough ?
cursive plume
like this? <button class='button1' onclick="jsgoeshere">Example</button>
jsgoeshere is gone be replaced by js obviously
pulsar bough
yea
cursive plume
what js goes there?
pulsar bough
documents.getElementById("").style.display='inline';
something like that
not 100% sure
cursive plume
document.getElementsByClassName("callout").style.display='inline';
you metioned
that earlier
cursive plume
did you change your mind?
pulsar bough
Class only lets you get Elements
then you need to get it out of the array
you could use class
just modify it to something like this document.getElementsByClassName("callout")[0].style.display='inline';
cursive plume
<button class='button1' onclick="document.getElementsByClassName("callout")[0].style.display='inline';">Example</button> so like this?

ayy thx, guess experiance is what i need the most,
ashen sky
@nocturne galleon That will help a LOT, and takes a lot of time to get. I've been using linux professionally for like 10 years, and still have a LOT to learn. 😉
nocturne galleon
^^ guess i got a long ways to go before ill be reomotely gud with it,
ashen sky
@vast echo I don't remember them being THAT different. Somewhere in /var/ seems to be default.
@nocturne galleon Depends on how fast you learn. 😉 I've started using linux about 20 years ago. But for desktop task, I know just about NOTHING. (Never really used Linux as a desktop OS.)
proper gale
@nocturne galleon if you are used to windows, it has a seemingly steep learning curve as simple things are different, even slightly. Really its just that you dont know what you are doing again, you get used to it, and you get better at it.
@ashen sky Linux for Desktop is basically the same as for servers, i actually run Ubuntu 19.04 Server on my desktop.
ashen sky
@proper gale I know, the basics are the same, but servers usually don't have any GUI installed, so the GUI specific things, are what I know almost nothing about. Only times I've used a linux GUI is whenever I forget to deselect it, during a manual installation. 😉

@ashen sky for the most part, unless you are doing GUI development, you dont really need to do much.
just, install it, and its a gui exactly how you would expect.

ah
hmmmm so you can manage docker in kubernetes?
but basically in docker for each setting you will have a port right? it's actually managable without kubernetes right?
sorry i haven't done kubernetes but want some insight before doing it
ashen sky
@proper gale I'm aware of that, I was thinking along the lines of customizations, and troubleshooting.
@ember mica You can easily run docker without kubernetes, but if you have a lot of docker instances, on multiple servers, kubernetes makes manageing easier.
proper gale
i never do any GUI customization myself
wait, thats not right, i did actually do it on my one laptop, which is gonna get its OS yeeted in about 6 months.
and its pretty stable, so, if you need to do antyhing with linux desktop, its not really different from server linux
ashen sky
@proper gale As I said, mainly uses it, when I install by accident. 😉
proper gale
you should try it sometime, not by accident
ashen sky
@proper gale Yeah, I will, whenever it just happes to be the right tool, and the software I need (Like MS Office, and the Adobe Creative Suite) is available.. Till then.. I'll stick with MacOS. 😉

ACS i can get, but why do you need MSO specifically?

Hi, I have a little question, which may sound stupid. But I still don't understand why it does not work: So I'm programming in c++ on xcode and here is the code with the issue:
cpuHandler.hpp
#ifndef cpuHandler_hpp
#define cpuHandler_hpp
#include <stdio.h>
#include <iostream>
#include <stdlib.h>
#include <Kernel/libkern/libkern.h>
#include <Kernel/i386/proc_reg.h>
#include <Kernel/mach/mach_types.h>
static void disable_tb(__unused void* param);
static void enable_tb(__unused void* param);
static void print_msr(__unused void* param);
#endif /* cpuHandler_hpp */
And the cpuHandler.cpp:
#include "cpuHandler.hpp"
const uint64_t disableTurboBoost = 0x4000000000LL;
static void disable_tb(__unused void * param_not_used) {
wrmsr64(MSR_IA32_MISC_ENABLE, rdmsr64(MSR_IA32_MISC_ENABLE) | disableTurboBoost);
}
static void enbable_tb(__unused void * param_not_used) {
wrmsr64(MSR_IA32_MISC_ENABLE, rdmsr64(MSR_IA32_MISC_ENABLE) & ~disableTurboBoost);
}
static void print_msr(__unused void * param_not_used) { // <-- here an error "expected function after funciton declarator"
cout << "The MSR is: " << hex << rdmsr64(MSR_IA32_MISC_ENABLE) << endl;
}
I really don't understand why xcode says there is an error at the print_msr function. The declaration is exactly the same as the other 2 functions and yet this one does not want work. Any idea of what is going on?
Thanks a lot in advance 🙂

You'll need to fix your calculator function a little, since you aren't passing operation to it, so you should have
def calculator(a, b, operation):```
and when you call it you should pass operation to it
```python
print(calculator(first_number, second_number, operation))```
then to use it in other code, you can import it and use it like so
```python
from boleanfunc import calculator
print(calculator(1, 2, "addition"))```@hazy summit np

Does anyone know multithreading
Can you send some links where I can learn how this shit works
Specifically in C using pthread
I am having lots of trouble with mutex/locking, conditions and semaphores
Any resources greatly appreciated
worthy dirge
C doesn't have a standard multi-threading library
If you know C++, it is a standard library and you can find a tons of multi-threading programming tutorials
round dome
he mentioned posix thread though, so what's the problem? Just because C doesn't have std::thread doesn't mean he should switch over
Just use pthread_mutex_lock & pthread_mutex_unlock
worthy dirge
Isn't it obvious that he couldn't find resources about it?
visual tapir
i managed to find some resources for pthread
like the man pages for a few functions
worthy dirge

My C knowledge kind of stuck at C89, learned it freshman year

cedar maple
do you have to do multi-threading or are subroutines also fine?
cause then you should just do callbacks. multi-threading in C is weird anyway with how C is structured.
as mentioned before in this answer, you see the example with threading, and alternatively one with a callback
proper gale
@visual tapir what is your assignment for?
cedar maple
huh didn't know pthread_t was part of the standard implementation
ought it was a lib
or later addition
also check IBMs doc for this, sometimes more helpful https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.2.0/com.ibm.zos.v2r2.bpxbd00/ptcrea.htm
imo
visual tapir
@proper gale Assignement is intended for us to learn thread synchronization, we have a program which will have tens or even hundreds of threads
we have one resource which needs to be accessed by many threads, and we need to make sure that stuff doesn't get messed up
proper gale
simple answer is a basic mutex, more complicated answer is a shared mutex
visual tapir
@cedar maple thanks for that, seems quite useful
what's the difference between those two
proper gale
basic mutex can only be locked by one thread at a time.
shared mutex can be locked by n readers and 1 writer
visual tapir
ok, so if I got it right, basic mutex once locked prevents other threads* from even reading, right?
proper gale
its not that it prevents the others from reading
its that it cant be locked.
in order to ensure that its not being written to and read from at the same time (which sometimes is ok) you would want to lock for both
the problem with a basic mutex here, is that only one thread can read from it at a time, even though there is no real reason for that
im guessing you are doing oop-like C, is that correct?
proper gale
is this C or C++? because a vector is a type in C++
visual tapir
C
if this was a std::vector i would have a lot less headache
this C vector is a void**, basically an array of pointers to structs
proper gale
ok, so, in the struct, add a pthread_mutex_t value,
init it with pthread_mutex_init which will take a pointer to that *_mutex_t
lock, unlock, and destroy are all basically the same.
before modifying or reading any value, lock it, after you are done, unlock it.
proper gale
mind you, check the error code ofc
i usually do this in C++, so i use std::mutex, and std::unique_lock, which makes this all much easier
fuck, i have this macro just to make my life easier
#define ROGUELIB_SYNCHRONIZED_SCOPE static std::mutex syncMutex;std::unique_lock syncLock(syncMutex);
that a global lock on just that scope, which isn't optimal, but ehh, good nuff.
lone hornet
so i'm making a recursion menu for class and one of the options is to output x^y and x^-y. if i get something like 0^-12, do i just make it say something like "the answer is infinity"?
visual tapir
the answer is undefined maybe?
lone hornet
yeah, i'll probably have to make a case for that since we can't reasonably compute 0^-y
btw, this is what i'm working with
proper gale
@lone hornet zero to any power is zero
zero to a negative power though, is undefined
but usually with computers you go with the easy option, which is just give back zero.
lone hornet
yeah but instead of my program giving me back a zero, it's giving me a floating point exception when i do any negative power
so right now, the easiest thing for me to do is to slap on another else if for that case and calling it a day
so far that hasn't work for me yet
proper gale
well, first up, i have no idea what order that shit is going in
but, if you are putting in zero, that makes sense, you need a special case for it.
lone hornet
yeah I'm currently working on it
proper gale
also, fun exercise with a recursive power function, you can do it with approx sqrt(exp) recursions.
lone hornet
i'll check it out when i get the chance
proper gale
its a pretty simple to implement
you can even use bitwise magic to remove most branching too
@lone hornet actually, here is exactly what i was talking about
int __internal_power_recursive(int base, int exp){
if(exp == 0){
return 1;
}
auto partialPow = __internal_power_recursive(base, exp >> 1);
partialPow *= partialPow;
partialPow *= base * (1 | exp);
return partialPow;
}
int power_recurse(int base, int exp){
if(base == 0){
return 0;
}
if(exp == 0){
return 1;
}
if(exp > 0){
return __internal_power_recursive(base, exp);
}else{
return 1 / __internal_power_recursive(base, exp);
}
}```that's actually pretty cool even with the bitwise black magic
worthy dirge
how do you get C++ syntax highlighting in discord

Anyone know how to dev a discord bot like role reaction / YAGPDB but in French ?
Or did you have tutos etc ?
proper gale
@visual tapir this does binary -> hex, reverse it and it will do hex -> binary
char nibble1Val = val & 0xF;
nibble1Val += 6;
nibble1Val += ((0x10 & nibble1Val) >> 4) * 7;
nibble1Val += 42;
char nibble2Val = (val >> 4) & 0xF;
nibble2Val += 6;
nibble2Val += ((0x10 & nibble2Val) >> 4) * 7;
nibble2Val += 42;
std::cout << nibble2Val << nibble1Val << ' ';```8 bit here
and ascii hex from a char value, not ascii binary
this uses a specific bit alightment to conditionally do a multiplication without a branch, not sure if its faster or not.

Rant:
So I'm wanting to write an app that manages my media server for me by auto populating it with new movies, tv shows and things like that from the Amazon Prime service and other sources in the future.
My problem is that the companies that I need to use their resources in order to get this to work, have THE WORST documentation on their API's that I need to use in order to get this to work.
The summarized idea is actually quite simple, "If you have enough money in a PayPal account, and no other movie has a higher priority, then buy the highest priority rank movie in the priority queue and then download it and import into Plex." Pretty simple right?
The issue is that PayPal has so many API's to figure out which to use and it doesn't easily document something as simple getting the balance of an Account. Amazon also has so many API's that it's a bit difficult to figure out which one I need to use to trigger a purchase, and then another API to download it.
This looks like it might become a fun Winter project or something, but just throwing a quick Python script together has shown me that this will be a tad annoying to get up and running with the API's. I just find it really funny that multi-billion dollar companies have worse documentation on their developer API's than small hobbyist developers over on GitHub.

to be fair, you are pirating if you rip content from Amazon anyway 🤷

I was trying to be legit about it, but yeah... torrents seem like a better idea. And I didn’t know it was pirating if I got them from Amazon. I though that if I purchased them, that it’d be legit and I was okay to download them to my server.
I’ll just try to only torrent what I legally own, but still it’s annoying to hunt for good quality torrents.

Create a test section of the while or for statement that will test if value1 is greater than 10 and value2 is less than 20. Finally, end the while or for statement by incrementing value1 by 1. In the loop body, write a println statement that will display the contents of value1
Its java
deep scarab
yeah idk what the point of this exercise is
worthy dirge
how about c do{value1=11;} while(false);
proper gale
@dim shard its actually not an infinite loop, i just have no idea what the point is
end result will be value1 = -(2^31) and value2 = 20 assuming int types.
but thats a technicality, while in theroy its not infinite, in practice it may as well be.
proper saddle
dim shard
@proper gale well her controlling statements said value 1 which is = 11 > 10, and value 2 which is = 19 is < 20 and only incrementing value1 the statements will always be true

proper gale
@worthy dirge a.insert(a.end(), temp, temp + 3);
worthy dirge
@proper gale I actually mean the whole temp array, but seems I can't
worthy dirge
it is strange that I can declare something likevector<pair<int, bool>[3]>
worthy dirge
No, I mean the [3] thing as a whole
proper gale
easiest way is std::vector<std::vector<std::pair<std::uint32_t, bool>>>
but, there is std::vector<std::array<std::pair<std:uint32_t, bool>, 3>> which is exactly what you are asking for.
worthy dirge
Yeah, but I am worrying the cost. I choose to make a new struct anyway
proper gale
dont worry about that minimal of cost when first writing anything
if its a problem, come back and fix it later.
besides, you probably wont do a better job than the people who made the standard library
considering that they are the same people that wrote the compiler

Anyone know how to create a procedure in sql?
todo = need replacing with appropriate code.
ashen sky
What exactly is the procedure supposed to do? Or is it just creating procedures in general?
plain cosmos
o Produce a procedure that assigns a new schedule for a given course. The procedure should accept a course code & start date as arguments then schedule each of the given course’s modules on consecutive (working / week) days. The start date must be at least a month in the future otherwise, a suitable error should be raised.
o Tips . . CURSOR, LOOP, SIGNAL
Am kind of understanding the logic and not at the same time...
ashen sky
That seems to be more than my SQL skills can do. But perhaps someone else knows how to do it. However, as I see it you already have the skeleton ready, which in my head seems to be
- Verify course code, and get modules
- Verify the start date is 1 month in the future, and it's a working day. (Or weekday)
- Loop through the modules
- Schedule the course at start day plus loop counter skipping non weekdays.
If you are allowed to do so, it might be a good idea to put some of the code in separate procedures, instead of just one, and call them in correct order.
plain cosmos
this is what i have so far
and I can't understand the flow of it .
you are right, that is a skeleton that just needs expanding. and logically thinking it makes sense but implementation for me does not.
I understand it and I don't at the same time 😦
ashen sky
Do you have a table with the course and the required modules for each course?
plain cosmos
Yes I have build the tables and imported the data into it.
I feel stupid right now, as am not understanding it fully
ashen sky
Then you can get the modules required, and thereby the number of loops to perform, in one step. So get the modules for the course, if 0 rows are returned, the course code is invalid, otherwise it's valid and you do not need to load the modules later. ;)
I would consider that step one.
Step two would be date verification. I don't know how detailed you need to do it, but I suppose you either just have to exclude weekends, or have a table with excluded dates. The code looks like MSSQL, but most of the SQL dialects have a function that allows you to take a valid date and get the weekday, either in numeric or textual form. So either select from the table with excluded dates 0 rows go, more than 0 means no. Or if you are just excluding weekdays, get the weekday from the date, and compare. For MSSQL DATEPART seems to be your friend.
Last assign the start date to a variable, as a date or datetime variable, then use DATEADD to add a day at the end of each loop.
But without actually solving the task in practice, and spending more time than I like at 22.30, I think this is the most help I can give.

You're welcome. 🙂

Hello, so i dont post much but im at desperation stage at uni, and ive been trying to figure this coursework out for a while, and it seems simple, rather new to RPi, Linux and C, even being 4th Year Uni, however i am struggling to figure out the GPIO Pins on the RPi Zero, i have the imagery from the documentation, however mine doesnt seem to want to work how i want it to, with on and off control, just either powers straight on, without it going off on control, partly because i dont really know 100% if its the right pin im typing to turn off, but im pretty sure it should mostly be off by default as it is and im pretty sure im somehow using purely power and ground without GPIO pin controls
Initial help if anyone could be as to what way the numbering is on it having it this way (below, in following message)
Also if anyone knows more about how to use shell_exec, also would be great if there was help once i had this wiring actually sorted and figured out 🙂 any help will be gratefully appreciated 🙂
worthy dirge

Atleast i know i was somewhat right with the wiring, thank you

In java, how would I generate two random strings such that the length of addition of two is less than a certain value?

i thought about something complicated but its awful practice...
like generate number convert it into string using utf8 throwing the strings together and if its too long try again
worthy dirge
That's actually a do-able idea
visual plank
I thought of something similar but i'd like a non-brute force algorithm
if it exists that is
worthy dirge
No need to brute force. You should be able to generate one random number within a certain range once at a time.
proper gale
@visual plank do you need randoms strings whose cumulitive length is under a specific value, or do you need numbers that when added and converted to a string is under a specific length?
visual plank
Nah the first one
Forgive me for not giving an example,
Say the magic number is 5.
So I want two random strings which when concatenated are of length less than or equal to 5
proper gale
so, not gonna help with generating random characters, but make a random number less than 5, make a random number less than 5 minus your first number, make random strings of those lengths, done
substitue 5 for whatever your magic number is

You have the String, get the (n) char of it, then you can convert it to an Integer with the second-last line, and with that number you can calculate again.

You can also use Objective C, but Swift is newer it's probably a better idea to use Swift. If you want to make a cross platform app, you can use a cross platform language (like C) for the core code / logic, and then build a front end with supported languages (Swift/Obj C for iOS [like Cocoa Touch] and Kotlin/Java/DART for Android [like Google's Flutter])

The subfolder of the show is always 'Season 1' but it's more than 150 folder so I want to find a way to automate it
ashen sky
You should be able to do it with powershell. Unfortunatly my console experience is mostly from linux, and Powershell is not that big there..
But the basic flow would be something like this:
- Make a list of "Season 1" folders with their full path.
- Loop the folders, and move all files to the folder above it. You can even change the name, eg. add a S1 prefix, if needed.
- Remove all the, now empty, "Season 1" folders.
In powershell land, I think you have a directory iterator to assist you on the job. But as I said, I've not done a lot of powershell scripting, so far I've only done some VMWare automation, like doing snapshots of production servers, before releasing new code to them. 😉

@worthy dirge not that im aware of, but i can give you one that will do it to that, or int main(std::vector<std::string>> args)
but, you will need to add a return value.

int my_main(int argc, string argv[]);
#define func main
int func(int argc, char** argv) //the real main()
{
return my_main(argc, &(vector<string>(argv, argv + argc).begin().operator*()));

#define main my_main
int main(int argc, string argv[]) //fake main()
{
cout << argc << "\n";

cout << argv[i] << "\n";
return 0;

@kind portal VSCode has C++ intellisense extension. It detects system include automatically after you install it so there won't be include error. You only need to compile by hand without using any build system.

@kind portal take a look at the cmake build system, it takes care of most of the details for you, its very nice.

yeah but why is the command g++ not clang?
proper gale
because its a mac.
macs use clang
its like that for compatability
there are a lot of things that you can just compile on mac from linux, where gcc is a thing, so those build scrips are compatable by just making g++ a symbolic link to clang

Does anyone here have experience using the asyncio module in python? I'm trying to write a minecraft server proxy/load balancer, and I'm confused about how asyncio handles closed connections.

Can Minecraft be load balanced?

Anyone help? So I need three 5V pins on an Arduino and only have one. Can I use any regular port to get 5V or am I fucked?
worthy dirge
@nocturne galleon If you know a thing called a bread board
runic widget
@last ingot Ok, so my question is about dealing with closed connections. Let say I make a TCP server using asyncio.start_server.
Here is a little example code:
import asyncio
async def echo_callback(reader, writer):
while True:
message = await reader.read(100)
if len(message) == 0:
# this means the connection was closed by the client right?
break
else:
writer.write(message)
await writer.drain()
asyncio.start_server(echo_callback, host='', port=6969)
i really dont recommend doing it that way, at all.
runic widget
With a normal socket server, you would shutdown and close the socket if you detect a closed connection, but idk how to tell asyncio to do that to the connection
proper gale
if asyncio works anything at all remotely similar to boost::asio, which considering they both stand for asyncio, then you are probably gonna break something like that.
runic widget
@proper gale how do you do this in boost? They are probably similar in design.
proper gale
if it was boost, i could actually answer your questions.
i mean, you would do it similarly, but with readsome and asio::write.
runic widget
Do you know how coroutines work Python with asyncio?
proper gale
i also know how multithreading works with boost::asio, so i could pull it off with much higher performance.
though, all you need is a transparent forwarding proxy, which already exists.
for example, pfsense has this functionality built into its port forwarding capabilities https://docs.netgate.com/pfsense/en/latest/loadbalancing/inbound-load-balancing.html
if you wanted to integrate with the minecraft server, so stuff like ipban still works, i can see why you would want to then.
runic widget
Well the problem to me seems to be that Minecraft servers can not be bound to the same port on the same machine. So my idea is a simple python proxy, where a bunch of proxy processes are started and are bound to the same external network facing port, but each proxy forwards data to whatever port a specific minecraft server is bound to locally.
proper gale
yea, port translation is nothing special
pfsense can do that
there are also existing solution for minecraft (bungeecord)
runic widget
But I want to do it on one machine, without having to have a pfsense router.
Also, the video that LTT put out about load testing the minecraft server used some "Waterfall" thingy that was supposed to do this, but it seemed to fail.
That is actually what inspired me to work on this, because it doesn't seem like this should be difficult to do on Linux.
proper gale
i mean, python doesnt give a fuck what OS its on
and if you are on linux, you can use iptables rules afaik.
runic widget
That isn't really true. Sockets don't work the same way in Python on different OSes.
proper gale
then someone fucked that module up, real bad.
runic widget
Also idk what iptables is lol.
proper gale
because boost manages to make it identical on all platforms, from C++
runic widget
In windows there is no SO_REUSEPORT option I think, which is the option required to bind multiple sockets to one port.
proper gale
this should be able to do it https://scalingo.com/articles/2018/04/20/iptables.html
runic widget
Actually, I think the difference is that Windows doesn't have separate SO_REUSEADDR and SO_REUSEPORT, they only have the former which allows for both?
Oh, I wonder if iptables will work for forwarding to different internal ports? It looks like it should
If iptables will work then I wonder why they didn't just use that? lol
proper gale
it will

ashen sky
Games are not something I consider serious. 😉 (However, I am aware of the complexity involved in the development. 😉 )
nocturne galleon
Serious games are games intended for other purposes than entertainment. It is a genre. In our case rehabilitation.
ashen sky
Ok. Don't know if I would consider that games, even though it's designed as a game. But I guess if designed the right way, they will actually work, and save man hours for the medical staff.
nocturne galleon
It's a bit more complicated. We have to build with patient limitations in mind , then develop the experience. We know that VS traditional training you get vastly better results and adherance in training, than without games. Same amount of medical staff though, mostly.
ashen sky
VS Training?

@nocturne galleon Ahh.. Thought it was a perticular type of training. 😉
dim shard
Hey what do u guys think?
about this java program?
Make sure when you find the path of the file to put double backslashes between drives and folders and the name of the file (\)
nocturne galleon
Sorry, I don't think a lot of people will run random java scripts 😄
nocturne galleon
I assume you're a beginner in programming. Considering this fact, this program is quite neat, but lacks several issues regarding coding style and best practices.
String concatenation in Java is best be done by using StringBuilder for example.
Also, checking for a true/false value using == seems awkward (but works too, of course, so this is more a personal opinion).
Naming your method "RWE" is considered bad style as well, just write "checkForFlags" for example or simply "readWriteExecuteCheck" to make things more clear.
And instead of declaring the variables as static class members, it would be more readable to just declare them inside your main method and pass them as parameters to the other methods.
To make a long story short: Just keep going, read more tutorials and read other's people code to learn from it (and don't start copying code from SO, you're learning nothing from that).
And another tip: Post your code as a GitHub Gist f.e. instead of uploading it, so people can just hit the link and read the code instead of downloading it and open it inside an editor 🙂
dim shard
how do i pass them as parameters
nocturne galleon
I strongly recommend reading about Java methods and how to use them properly.
To make a long story short:
public static void main(String args[]) {
int foo = 3;
mySuperDuperMethod(foo);
}
public void mySuperDuperMethod(int foo) {
// Now use can use foo
}
vast echo
If you declare foo again in the method that takes precedent
So don’t do that
That’s not a comment about the above code, just an additional point on top of that
Also depending on the language you need to pay attention to pass by value as compared to pass by reference
true field
proper gale
@nocturne galleon dont forget about java's use of static, that code almost works
also, @dim shard what the fuck is this? i dont think ive seen this style before. ```java
}
else {```
thats not uncommon
proper gale
that specifically, i havent seen before
ive seen it split a lot, but not that
main way ive seen that on multiple lines is like this
}
else
{```😆 wtf is that else
Makes it reads like another block of logic, which actually should be following if closely

hey how to do greater than ">" in kotlin
it returns an error
`while ((x != c) and (v <= b) ) {
val c = findViewById<View>(R.id.user_input)
validate.setOnClickListener{
result.setText("")
if (x < c)
textview2.setText("give a smaller number")
else
if (x >= c)
textview2.setText("")`
amber glen
oh man kotlin is still alive
vast echo
Your problem is not using braces
When you do an if/else without braces only the immediate line is included in that statement
So at the bottom when you have any else with an if in it, the line after the if isn’t included in the else and is instead run in the main body
Meaning that you have an if without curly brackets or and immediately indented line to the compiler
Even though there is an immediately indented line after
Because that line isn’t included because the if is the immediately indented line of the else
Hopefully what I said makes sense
Bottom line, it’s technically possible to use if’s without braces but just don’t
Also in the future post the error you got
Makes it easier to figure out what’s wrong

Another thing- please name your text view variables

@vast echo no, thats not hte problem here

Anyone proficient with NodeJS? I am able to establish a connection to my server using NodeJS, however when I try to write to the socket to log in, it doesn't seem to work. All incoming data from the server is terminated with \n. I feel as if I'm missing something simple. Several lines are sent from the server before the "LOGIN" is sent. Sample code below:
var net = require('net');
var cclient = new net.Socket();
cclient.connect(8000,'myserver.mydomain.com', function() {
console.log('Connected');
});
cclient.on('data', function(data) {
console.log('Received: ' + data);
//cclient.destroy(); // kill client after server's response
fromsrv(data);
});
cclient.on('close', function() {
console.log('Connection closed');
});
function fromsrv(indata){
if (indata === 'LOGIN'){
cclient.write('connect USER PASS\n');
}
}
