@last ingot appreciate the thorough response. Yeah I was trying to understand why it worked that way. I am more versed in powershell but looks like BGinfo does not accept ps1 scripts to gather info from

Someone sell me on using an ORM. I’m having to for work, and since I already know SQL quite well, it’s killing me. Is it wrong to hate the very concept?

[full berry]

Um nosql is vague... And it includes other non sql dbs....

And you saying python > c# basic... In terms of what?

Things like document based db are also nosql...

Also vb arrays start at index 0...

Its in this case 0 is reserved already

[upbeat folio]

Document storage has its place, and when dealing with ginormous datasets with minimal relationships, its performance can’t be beat. But it starts to lose its edge when you get into smaller applications with smaller datasets, especially if the relations between those datasets have any order of complexity to them.

At least in my reading and experience.

Anyway, I’m not here to argue the merits of RDBMS over NoSQL. I’m here to complain about a really shitty ORM.

[full berry]

Document based databases can hold more complex relationshipd better than a structured one (like in sql) for instance graph databases

I will agree that there are places for everything

and in terms of speed for simple queries relational ones like the familiar sql is fast af

furthermore id like to state that there is a difference between the db that everyone is familiar with and the language sql

[upbeat folio]

Care to provide a link where I can see an example of that level of complexity? Not arguing, that’s just counter to what I’ve read before, and I’m eager to see things done well by people who know what they’re doing.

Hello everyone, I need your help. My friend and I have a intermediate knowledge of C# and we want to do a project to show off out knowledge.

For a project we don't want a Console Application but a Windows Forms app, and the project can include SQL Databases. Just don't give us a task of making a mobile app because making UI is hard AF for both of us(Android UI).

I have been looking at Graph Databases, but have not seen a good example where a properly written and indexed query in a relational database wasn't just as performant. Anyone have some good examples of scenarios where this would not be the case?

Normally. Net but I'm talking purely database engine for this.

Everyone here refuses to touch jQuery. Not sure why exactly because I personally have never had the need for it.

Ah

I use frameworks so its basically useless for me lol Polymer.js and Vue.js mostly

[glad terrace]

jQuery alone is about 1/4 of our apps total minified file size.

Its a web app that gets deployed to well over 100k devices overnight so it does need to be as small as possible to not miss deployment deadlines. And then updated assets and 'settings' also.

[ionic hull]

A few kb won't make any difference 💁

And I can say that based on experience

[vestal glen]

Vue is <3 friends. It solves so many issues, thanks to being reactive. But sure, no need to do everything on the client side, agreed.

[cloud knot]

@nocturne galleon time to pull out the good old console.log to see where the code goes and what values it sees

Hiya all, im back with another programming question for school

#include "NXCDefs.h"
task main ()

{
OnFwd(OUT_A, 75);
Wait(10000);

}

[vestal glen]

so far I see no question?

[brazen sluice]

im typing it up 😃

i gotta formulate it properly

So, the code should make the nxt 2.0 robot drive in a circle if the number is below 600 and stop if it isnt

but for some reason the code doesnt work, (we use https://sourceforge.net/projects/bricxcc/ , but sadly i have no idea what the code language is)

we cant load the code onto a robot unless it "works" but i dont know why it doesnt work

[vestal glen]

what is "doesn't work" in this case?

[brazen sluice]

it says one of the { is in teh incorrect place

[vestal glen]

oh, right, I see

you have a ; after the if

making it an empty block

(always include the exact error you get...)

[brazen sluice]

im sorry, kinda new to programming 😃

[vestal glen]

describing a problem exactly isn't something limited to programming 😉

[brazen sluice]

That fixed it, thanks

Anyone here familiar with Docker?

[glossy bluff]

Hello everyone! Is this a good channel to find web dev help?

[split condor]

Yes to both of you (@broken panther and @glossy bluff)

[broken panther]

Hey. I have a Wordpress site built with docker-compose. What would be the best way to backup and restore it? I need to migrate it to a different server.

This was built on a version 1 .yml file and I can't find the Dockerfile. Whenever I try to docker-compose up on my other server, I keep getting an error saying it can't create a container for the Wordpress image, though it does create a container for the mysql image.

[glossy bluff]

Thanks @broken panther !

I'm having trouble my usermeta custom fields in Wordpress. I was stuck trying top get them to update using a dropdown onchange but I've worked out the problem to only needing a proper SQL command. Here is what I have so far and it currently works but it creates a new row in the table instead of update the current value. Any SQL guru's out there that can help me out? It would be greatly appreciated.

include_once $_SERVER['DOCUMENT_ROOT'].'/wp-load.php';

ini_set('display_errors',1);
error_reporting(E_ALL);

$userid = ($_POST["userid"]);
$meta_value = ($_POST["refunddd"]);
$meta_key = 'refund_status';
$user_id = $userid;
$user = get_user_meta($user_id, '', '');
$refundstatus = $user->refund_status;
$prev_value = $refundstatus;

/* Start database connection */
$servername = 'servername';
$username = 'username';
$password = 'password';
$dbname = "database-name";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "UPDATE `wp_usermeta`(`user_id`, `meta_key`, `meta_value`) VALUES ('$userid','refund_status', '$metavalue')"; 
 if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();

[broken panther]

I think you meant to tag Ben

[split condor]

Can you share the error Docker is throwing when attempting to create the Wordpress image?

@glossy bluff, the UPDATE command is something like..

UPDATE table SET column = value, column_two = value_two WHERE id = id_or_whatever;

Keep in mind, a quick search of something like "sql update syntax" could yield an answer quicker than us (:

[broken panther]

@split condor

[split condor]

Can you share your docker-compose.yml and Dockerfile?

[broken panther]

Give me a sec

[split condor]

error500, something else to note about your setup: It looks like you're open to some SQL injection. Here is a bit of information on why this is an issue and mitigation for PHP: https://stackoverflow.com/a/60496

[broken panther]

I'll show you the Dockerfile in a sec. Having connection problems

[glossy bluff]

@split condor Thanks! It's easy to google something when you know what question you are looking for. This is literally pieced from other Google searches and reading as much as possible but I don't quite know SQL

[broken panther]

@split condor I think I found the problem. I pushed the image to Docker's registry and the Dockerfile wasn't there

I tried using the official images from Docker, but they don't seem to work with my environment

I meant I tried using the Dockerfile from the official image*

[split condor]

Ah, gotcha

Glad you figured it out (:

[broken panther]

@split condor up for some help with Docker?

[split condor]

Sure, @broken panther

[broken panther]

Alright, so I went a different direction this time. I bashed into the running container from my original server and made a dump.sql, then I SCP'd the Wordpress files to my new server (the one I want to migrate to).

I mounted the backup.sql files and the Wordpress files as volumes in my docker-compose.yml file, like so:

version: '2'

services:
   db:
     image: mysql:5.7
     volumes:
       - ./backup.sql:/docker-entrypoint-initdb.d/backup.sql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: password
       MYSQL_DATABASE: wordpress

   wordpress:
     depends_on:
       - db
     image: johnnyetz/wordpress:2
     ports:
       - "127.0.0.1:8080:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_PASSWORD: password
     volumes:
       - /var/www/html:/var/www/html```

This is my wp-config.php file:

```php

define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'root');

/** MySQL database password */
define('DB_PASSWORD', 'password');

/** MySQL hostname */
define('DB_HOST', 'db:3306');

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');```

Then I have a long list of docker-compose --verbose up

I get some mysql errors and I can't connect to my server

I'll highlight some errors I noticed

This one repeats itself pretty often:

wordpress_1  | Warning: mysqli::__construct(): (HY000/2002): Connection refused in Standard input code on line 22
wordpress_1  |
wordpress_1  | MySQL Connection Error: (2002) Connection refused```

After that the containers stay running, but I can't reach the server

@split condor

[split condor]

On the MySQL container you'll need to expose port 3306

expose:
  - "3306"

expose allows access to connected services only, while port binds to the host machine

Depending on your setup defining it under ports may be a better option; though you will need to consider security a bit more in the latter

[broken panther]

Alright, let me try that

Like this? I did it and I'm getting that same error.

[split condor]

Yeah, that should be alright

[broken panther]

Could it be some config problems from my old database?

[split condor]

Just to verify, you are able to simply ping the other service from either container, correct?

[broken panther]

What do you mean? I usually get them up with docker-compose up

[split condor]

Yeah. If you enter them via exec are you able to simply send a ping request out to another?

For example, opening up a session with db are you able to ping wordpress?

[broken panther]

Let me check

How do I ping other services from within the session? I bashed into db, but how I do I ping wordpress from there?

[split condor]

Using the ping command

It should be built into the image

[broken panther]

It says ping command not found

[split condor]

That's depressing

What is the base image?

[broken panther]

It's wordpress php7.1. The official Docker image

https://github.com/docker-library/wordpress/blob/d775299ddae6dafa232166f44b7c03d23ddf7bb6/php7.1/apache/Dockerfile

That one

I have a different repository in my .yml file because I thought it'd back up anything from there, but it doesn't :p

Also, just realised my wordpress image has "0.0.0.0" listed

Fixed that

Still not running, though

[split condor]

Yeah. The 0.0.0.0 is a mapping on your host machine.

You should be able to get ping via a apt-get install iputils-ping

[broken panther]

Installed it. ping wordpress doesn't work. Does it have a different syntax?

[split condor]

That should be correct

Docker compose should map wordpress to the proper container

[broken panther]

Ah, no wait

[split condor]

Oh, I see what you mean

Update the package list first via apt-get update

[broken panther]

It can, apparently

[split condor]

Alright, that's good

I'm mildly confused, haha

There's gotta be something small we're missing

[broken panther]

Yeah, though, it's weird. I first tried this on my PC and it was working, only that it wanted to install Wordpress, meaning it wasn't taking my backup.sql file. I never know if I fixed that or not because I started changing the database passwords and usernames from both the .yml file and wp-config.php, but then I never got it to work

[split condor]

Does the database container startup without any issue?

On the database setup, you'll need a volume mount for the actual data too

[broken panther]

It's giving that error I showed you:

wordpress_1 | wordpress_1 | Warning: mysqli::__construct(): (HY000/2002): Connection refused in Standard input code on line 22 wordpress_1 | wordpress_1 | MySQL Connection Error: (2002) Connection refused

You mean to persist data? I plan on doing that once I can start it 😂

[split condor]

lol

fair enough

What is the log looking like on the database container?

[broken panther]

There's a lot going on there, do you want me to CP everything? :p

[split condor]

Ehh

Do you see anything glaring at you? Any errors, etc

Me, too, mate 😩

[split condor]

We have established that MySQL is running, you have network connectivity between the two containers, and have exposed the primary MySQL port

That should be it

[broken panther]

I'm a noob at this, but I'm usually able to find what I'm looking for after a few hours of google, but I've been on this for days, lol.

[split condor]

darn

Let's just go over it again

So listing all of your containers, for db do you see that port 3306 is exposed?

[broken panther]

I fucked over this when I mounted the backup volume. I could try not doing that and see if it works

[split condor]

excellent idea

[broken panther]

I'm still getting the error, but I'll delete the image and pull again

no dice

[split condor]

😠

Pinging db is ok from wordpress, yeah?

[broken panther]

Yep

[fiery onyx]

Hey guys, I'm curious. Is it possible to code a meltdown exploit using C++ in visual studio simply for educational purposes? Like I'd like to try inserting a value in memory and make something to try and read the value at that address... Idk if this is possible in C++ though

Tbh I'm new to C++

Not new to scripting/coding though

[split condor]

Do you have the MySQL client on the wordpress container? mysql

[broken panther]

Apparently not, but I just downloaded the official version, I'd like to think I have it on the image from my repository, given that I pushed a working image

[split condor]

haha

Try connecting to the db container with the mysql client

mysql -h db

@fiery onyx, here is a project that is aiming to check if a system is open to Meltdown; so sort of similar: https://github.com/raphaelsc/Am-I-affected-by-Meltdown

[broken panther]

What's the package called? install mysql doesn't work

[split condor]

Try mysql-client

[broken panther]

yep, that works

[split condor]

Add the p flag to that command

Then enter whatever your MySQL root password is

[broken panther]

So it'd be mysql -h -p PASSWORD db

?

[split condor]

Something like mysql -h db -p

You will actually type out your password

or copy/paste it

[broken panther]

Yeah

I'm in

[split condor]

ok i'm confused again

We have established that you can connect

For some reason Wordpress is having an issue doing so

Can you leave the port off from WORDPRESS_DB_HOST? It shouldn't be required as you're using the default port. Maybe it is having an issue parsing that; that's just a shot in the dark though.

[broken panther]

Do I just delete the port or the entire line?

[split condor]

The port

[broken panther]

Done it. Same thing, sadly

[fiery onyx]

@split condor Thanks.
Who named Meltdown, anyways? And why does it have fancy logo? 🤔

[split condor]

https://meltdownattack.com/#faq-why-meltdown

The only thing I can think to do is try exposing the port on the machine as well

Replacing expose with

ports:
 - "3306:3306"

[broken panther]

Alright, let me try

[split condor]

I was under the impression that Docker compose linked these services together automatically

Maybe we actually need to define a link

[broken panther]

Getting an error:

ERROR: Encountered errors while bringing up the project.```

I have this line in wp-config, should I remove this? 🤔 

``define('DB_HOST', 'db:3306');``

[split condor]

Perhaps

It looks like you already have MySQL running on your host machine

no biggie

Jump back to expose then maybe we can try an actual link

[broken panther]

Alright, done it. By linking you mean using links: ?

[split condor]

Yeah

links:
  - "db"

[broken panther]

On the wordpress service?

[split condor]

Yeah

[broken panther]

Do I delete depends_on: ? 🤔

[split condor]

I don't believe so

[broken panther]

😩

[split condor]

Still broken?

[broken panther]

Yeah

[split condor]

of course it is lol

Could you try restarting the host machine? Along with making sure everything is up to date.

[broken panther]

Yeah, I'm gonna try the whole process again

[broken panther]

@split condor so I found a new error (lol).

I made a new droplet on DigitalOcean just to try out something (have free credits anyway). I followed the official guide to install Wordpress and it works, then when I do the same in the other server, I get a version error.

Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

The funny thing is, I'm in the latest version

This is docker --version's output Docker version 18.06.1-ce, build e68fc7a

@broken panther Not sure its the version you actually have installed but the format of the compose file. https://docs.docker.com/compose/compose-file/compose-versioning/

[broken panther]

The format is the exact same from the docker docs tutorial, works in one of the droplets, but not in the other one.

[glad terrace]

Double checking couldn't hurt I guess. There is an upgrading section but if that looks good IDK. Learning docker is still on my to do list lol

[broken panther]

The only difference between the 2 .yml files was that one had volumes (I added them to backup my site), but then I modified both files to make them the exact same.

This thing's been driving me crazy, lol

[glad terrace]

Version 2 to Version 3 It said what changed was how volumes work so probably your issue then.

[broken panther]

I fixed that issue. It didn't work without the volumes either. I don't know what I did, lol

[glad terrace]

Ah

[nocturne galleon]

guys I have the best Idea for version control

make a discord server

and put the code in messages

each branch is just a separate text channel

[vale maple]

But how do you gonna merge branches with that...
Well, thinking twice you could write a bot to do that.... So i think this is a perfect idea.

[nocturne galleon]

Trust me, all the big name software companies use this. Even discord themselves

[prime crescent]

Lmao yeah good idea, let's put all our code on a messaging app with semi-frequent server outages and no guarantee that the server wont be deleted

[stiff gull]

thats the best kind of security

"insecurity"

isn't that how LTT manages their servers? 😛

[upbeat folio]

Okay, so I built an endpoint for work that accepts JSON, and has a format validation component for one attribute in that JSON. A developer joining the team to help us launch complained this morning that the endpoint failed in error when passing that value as null. But in my testing, passing it as null has the desired effect and does not fail in error. That’s when I learned that the guest developer was sending everything as strings. So “thing”: “null” instead of ”thing”: null.

Is there any reason why he should be sending null in a string like that, or am I right in judging him hard for finding the one behavior that would cause my endpoint to fail?

(note, I fixed my endpoint to account for this, but I’m trying to see if I’m right to be annoyed)

[vestal glen]

"null" isn't null. If you want the null value, don't put it inside a string.

(though your endpoint should probably handle arbitrary json input gracefully)

[wary jetty]

A python AI I'm working on, I'll add timestamps and names later on, for now it asks questions. I answer them.

Maybe I'll add names now for future screenshots

BTW does this fit here? It is bot development.

Done

I'll try for time stamps, too

The bot main menu has a time stamp

(Using QPython, may port over to Linux and Windows when the Android version is finished)

[thin cobalt]

anybody know if I can make a usb-hid device seem connected using csharp?

it needs to be a specific VID and PID

[nocturne galleon]

ofcourse it was a meme

[supple abyss]

hey, does anyone know how I can tell the sequence of line execution in a C program?

I need to know which line of code gets executed and when

[stiff gull]

they're linear

it starts at the top, and it goes to the bottom

1 by 1

@supple abyss

[supple abyss]

great, thought so

unless you have a function which calls another function, then the program will jump to the specified place, right?

[stiff gull]

yeah but it still follows the top to down thing, per function

void foo()
{
   bar();//3rd
}

void bar()
{
   //4th
}

//entry
int main()
{
  int i = 0;  //1st
  foo(); //2nd
  printf("hello"); //5th
  return 0; //6th
}

very basically explained though

there's more going on

scopes and all that

but you can assume that if you write something first, it'll get executed first

[supple abyss]

great, thanks man!

another question I have; I need to check this piece of code if it has any errors and if it makes sense

my thinking is that the loop wont even be executed because 9 mod 2 is not 0

and i is decreased two times

then we have 7 mod 2, which again is not 0

no wait

it will be executed every 2 numbers

because thats when i mod 2 == 0

so the output would be 8 6 4 2

[chrome mason]

One message removed from a suspended account.

[stiff gull]

I'm sure that's an infinite loop @supple abyss 😛

its a subtle error

its not even a mistake logic wise haha

coincidentally I had such a mistake happen to me pretty recently

[supple abyss]

could you explain where the error is?

[stiff gull]

I mean.. I'd be doing your assignment haha

[supple abyss]

this is a question from an exam from 2016

i have my exam tomorrow lols

[stiff gull]

protip: ";"

[supple abyss]

line 2? but the compiler ignores whitespaces

ohhh

while loop

it has a ;

when it shouldnt?

[stiff gull]

yes

[supple abyss]

damn I wouldnt have found this error at an exam

[stiff gull]

know that {} can be used to create a local scope

the ; ends a command so the while(i > 9) is a seperate entity from the {}

so since i is never decreased since it has no code to run it'll loop infinitely

[supple abyss]

in other words; do things with {} not require ; at the end?

[glossy hare]

wouldn't it just error out tho?

wait is this C?

[supple abyss]

i copied it in my IDE and it didnt return no errors

yes C

[stiff gull]

int main()
{ //function scope

    { //local scope
        int i =0;
                printf("Hello");
    }
    //i is destructed
    int i = 10; //its fine since i isn't used yet

}

[glossy hare]

ah. i was thinking java.

would that still work in java?

[stiff gull]

no clue, I main in C++

[glossy hare]

gotcha

c++ damnn lol

[obsidian bluff]

Curly braces are not required for a while loop. If you leave out the curly braces it will treat the next statement as the full loop contents

since the semicolon is immediately after the while loop it's just an empty loop that runs forever

[stiff gull]

and yes,

int i = 0;
while( i < 9)
     i++;

is legit code

[obsidian bluff]

^ right like that

[glossy hare]

but it just treats the line right after

[stiff gull]

the {} aren't required, but are used to create a scope and execute blocks of code rather than a single line

[glossy hare]

not the whole list of lines for example in that code

[stiff gull]

though even that can be done by using , instead of ;

[obsidian bluff]

, does have the restriction of not being able to define new variables.

[stiff gull]

while(true)
    printf("Hi"),
    printf("This"),
    printf("repeats");

[obsidian bluff]

No \n 😡

[stiff gull]

ah right haha, I usually wrap my printf's or use std::cout/endl

[obsidian bluff]

👌

[glossy hare]

good to know

[stiff gull]

so yeah whatever comes directly after a while or for is run

so if thats a {} it means it runs that entire block

[obsidian bluff]

now exercise for the reader.

int i = intreturningfunction1(), intreturningfunction2(), intreturningfunction3();```
What's the value of i

[stiff gull]

whatever is the result of intreturningfunction1() iirc

[glossy hare]

not 3?

[obsidian bluff]

Wasn't it 3? Now I'm actually not sure anymore lol

[stiff gull]

yeah I'd actually have to look it up though

but this is just shitty code 😛

[glossy hare]

you could do that tho?

[stiff gull]

return values don't have to be stored

[glossy hare]

instead of functions could those just be 1, 2, 3?

the literal ints

[stiff gull]

no

[glossy hare]

okay didn't think so but now im questioning everything lol

[obsidian bluff]

In that context you could do something like
int i1 = 1, i2 = 2, i3 = 3; to define multiple variables of the same type

But that's not a comma operator anymore in that situation I think

[stiff gull]

that is fine yeah

[glossy hare]

yeah. i mean like the first thing you originally posted @obsidian bluff was setting the one variable

[stiff gull]

but the reason the functions work is due to the fact their return values don't have to be stored.. It's just icky and potentially UB to change a variable that is used in the other functions as well

[obsidian bluff]

it's actually like this (intreturningfunction1(), (intreturningfunction2(), intreturningfunction3()))

[stiff gull]

for example

int Foo(int x, int y)
{
   return x / y;
}

int i = 1;
Foo(i++,i++);

this is UB

[obsidian bluff]

the comma operator evaluates both expressions and returns the return value of the right-hand expression

Really? is it UB?

You'd think that they are avaluated from left to right

[stiff gull]

order of operations isn't strictly defined here

[obsidian bluff]

You probably know more than I do about that.

[stiff gull]

C++ has lots and LOTS of UB

C is generally safer in that regard

[obsidian bluff]

👻

Once you get in the territory of "indeterminately sequenced" things get spooky

https://en.cppreference.com/w/cpp/language/eval_order

This entire page is spooky

Reads like it's more geared towards compiler developers.

[stiff gull]

my example is in there

you know whats also UB, almost every bit of code that uses union

due to strict aliasing

union
{
    int i;
    float f;
}
//initialise i
i = 10;
//reading from or writing to f is now UB

though one would usually use this to use bitwise ops on floats

C++ is a place where dreams go to die

instead if you want to use bitwise ops on a float, you'd have to memcpy it to int, do your ops and memcpy it back

[glossy hare]

this is why we are moving our old c++ apps to c# lol

[nocturne galleon]

.Net Core works on all major platforms @last ingot

[proper saddle]

Core is already on 5? Last time i used it, it was still on 2.x

[nocturne galleon]

I thought so too. Maybe the graphic is just wrong.

It's on 2.2

[broken panther]

The graphic is wrong about the the version number only.

[proper saddle]

I think core was originally called framework 5, so that might be why.

Oh yeah, in green it says asp.net 5

[stiff gull]

@last ingot using C++ doesnt guarantee platform support at all lol

it purely depends on what you have to do, but anything thats not command line and requires a window will automatically bind you to a specific OS unless you rewrite that piece of code for every platform you want to support

same for rendering

which is where libraries come into play

or engines

[nocturne galleon]

Why @last ingot ? lol

Sound logic

[minor mauve]

I haven't used C# in almost a year at work. Only when working on legacy code and most of our products are stable.
Our team has been using Go and I really enjoy it. If I ever have to get a new job, I'd probably look specifically for teams/companies that use Go.

[thin cobalt]

Anybody good at ASP.net?

I have a file in the format of value1, value2 <crlf> value1, value2

And I want to display for every line in the file that value 1 as a <h3> and that value2 as the href of an <a>

This is a asp.net web pages btw

[proper gale]

@stiff gull much of what is UB in C++ is in reality IDB, so get to know your compiler real well, and don't use a different one.

[stiff gull]

@proper gale this is very very ill-advised

the problem with UB is that the compiler is allowed to do whatever it wants there, even a update could break what consistent behaviour it had for it

UB is to be avoided, not embraced

It just means you have to be aware of what is and is not UB and work around it

@half forge before/after shots? Im not seeing the problem?

[warped inlet]

Hey, im completely new to visual studio and c++ and im following a tutorial, I tried to build a project and this error occured, anyone have any ideas on how i can fix it?

[stiff gull]

why .net if you're using C++

you're not doing any CLI are you?

[warped inlet]

Nope

[stiff gull]

cause that'd be a hell of a start

[warped inlet]

lol.

Im not sure why its using .net

I may have installed it, but i dont think im using it

i am using someone the tutoirals framework

not sure if that has any CLI in it

[warped inlet]

So i tried doing another really short and simple program, but that build failed with no errors...

[nocturne galleon]

What made you pick C++?

[warped inlet]

Well, to be honest, I just wanted to learn a new language. The only language in my schools curriculum is python, and i wanted to try a new language.

I'd be welcome to any suggestions though.

@nocturne galleon

[nocturne galleon]

I would have a go with C# imo @warped inlet

[stiff gull]

@warped inlet if there's errors it should say so in the output window

however that program should run and pretty much exit immediatly, you might see a very quick CMD pop up if anything

in case you might have confused that with "the build failing"

[nocturne galleon]

But ya, the above seems like it may be the case. Just put this at the bottom:

std::getchar();

It will wait for you to press a key before exiting the program.

[obsidian bluff]

And also make sure to add a newline character

[proper gale]

@warped inlet python to C++ is a bad idea, C++ is fucking hard (and about as different as you can get without going functional). As Eagle suggested, C# would be a good inbetween choice.

[warped inlet]

Alright, thanks guys.

[stiff gull]

@warped inlet Unity is a good start if you wanna get some games going and learn C# along the side

[warped inlet]

Ah, Il look into It, @stiff gull Thanks!

[upbeat folio]

I love it when the UI developer overrides the API design because he can’t keep up and feels like he ideologically shouldn’t have to try.

[nocturne galleon]

But you're there to cater to all his needs, right? Lol

[proper gale]

no, no, it is.

i code in it as well, consider perspective

to me its not particularly hard, but to someone coming from python, it is.

ok, doesn't mean its not a hard language

if you are a masochist and want to take the hard route, go right ahead,

C++ is a hard language, not because the language is hard, but because the libraries are confusing.

like, what is stoi, you know what that is, i know what that is, but it should still be called stringToInt or something similar.

most things are std::string or char*, no?

or at least have a constructor from that so you use std::string.c_str() then it makes its type from that.

how does this pertain to C++ (not) being hard?

ok, that was never my point.

i was saying that its a hard language to learn, and arguably hard to use.

ok, counter points
C++ is non garbage collected
C++ has a fuckall of buildsystems
C++ requires functions to be declared before they are used
the C preprocessor is a dick, period.
headers cause problems, and its hard for IDEs to properly show you how they will be included.
the language is not standardized across compilers.
operator overloads can sometimes be super intuitive, other times not.
libraries have a tendency to have confusing and/or overly long names.
namespaces are a necessary dick to work with.
and a big thing from python, its forced statically typed.
and this is besides the more minor syntax differences. the largest of which would probably be automatic this-> that python doesn't do.

Ofc, c# shares some of these, but probably best not to throw them all at someone at once.

nobody can be perfectly fact only.

and while yes python had different run times that do behave different, there is a standard one, C++ doesn't have that.

you could say GCC is the standard one, but its really not because of extensions, Clang isn't for the same reasons, and MSVC is horridly off.

[obsidian bluff]

Everyone look at how hardcore I am

I'm not making excuses and took that HARDEST route VOLUNTARILY. Because I LIKE DIFFICULTY

But at the same time the way I took wasn't hard at all because I am super hardcore

🤐

I would personally put time.time() on the left to make it clearer.

Like time.time() >= timestamplewhatever + 300

You would never say: this certain moment in time plus 15 minutes was after now so it hasn't been 15 minutes since the event occurred.
You would say: it is currently less late than 15 minutes after the event happened.

[proper gale]

i would do it now - then >= 5 minutes

[obsidian bluff]

Even better

[proper gale]

to me, even clearer

also works in reverse if you abs it.

[obsidian bluff]

That's fair

Tbh I didn't even read all of it 😅

I've done a fair share of condemning people for being "lazy" myself

I have the same mindset

But it sucks

You spend years and years doing nothing productive

Or at least a lot less than you could've done if you took the easy route here and there.

I had such a shitty mindset that I refused to use a library for openGL context creation or even audio playback

I did it all using windows only function calls

And it was hell

True I did get a better understanding of windows under the hood

Not only did I spend time doing useless shit it was part of the reason that I'm still technically in what americans would call high school at 20 years old

And I'm still not learning about what I'm really interested in in school

People are passing me left and right and it feels terrible

Computer programming duh

And even my knowledge of computers is not where it could have been if I had just studied for school

Because I would be in uni by now

I respectfully disagree

Uhhh sure

https://discordapp.com/channels/375436620578684930/380527803604664324/522193842108366869

I don't think I can't code

Well I barely know CPP

Most of those programs were written in it

But they're all mostly terrible

Cpp, c++, potato potato

Like cpp is freaking complex dude

I don't know half the things there are to know

That's why I say "I know how to use C++" and not "I know C++"

lvalues rvalues pass by reference copy constructor move contructor virtual destructor dynamic_cast vs const_cast unique_ptr shared_ptr weak_ptr etc. etc.

I can't see the forest for the trees

I would argue that C++ is more difficult than even some assembly languages

I reinvented the circular buffer on accident

While trying to code something

my problem is not problem solving

My problem is knowing all the tiny semantics

Like... Every time I want to get started on a big project I get lost in a rabbithole of cppreference.com pages

Every time you want to know about one thing you have to read about the next and then you have to read more and more and more

And I don't want to just "make it work" if the code is going to be shit

[proper gale]

@obsidian bluff i have caught myself reading cppreference for well over an hour by accident.

[proper gale]

all sorts of things.

[obsidian bluff]

It sometimes seems like with C++ that you either know everything or you know nothing

And in the inbetween you're just fucking around like an idiot.

[nova moth]

I have a problem. I want to learn how to use CUDA, but my GPU doesn't support. Do you know of places on the net where I can run my code?
P.S.:Don't have money for new GPU now

[obsidian bluff]

I hear that using openCL is the better option.

[stiff gull]

@obsidian bluff cuda us superior in every way, OpenCl is what'd you use if you have a AMD gpu

@nova moth no since it would literally cost performance and power, and ppl would just run miners on em :P

[obsidian bluff]

I hear the performance difference is negligible if used properly.

And you have the added bonus of being more portable

[stiff gull]

Except OpenCL runs worse on Nvidia

[obsidian bluff]

I'd say that's NVIDIA's fault but okay.

[stiff gull]

why would nvidia invest in OpenCL performance if they have special hardware for the same compute purpose called CUDA

[nova moth]

I just want send my cpp project and be given the results from it

[obsidian bluff]

I'm not saying they would. I'm saying they should

And if consumers say "We want openCL compliance and performance" they will have to answer

[stiff gull]

@obsidian bluff people choose the easiest and faster thing to work with, that is CUDA on both points

being able to write C++ on GPU is amazing

[obsidian bluff]

Hmmm if you couldn't tell by my profile picture I'm not a huge fan of vendor lock-in

[stiff gull]

well then AMD should just implement CUDA support huh :P

[obsidian bluff]

¯_(ツ)_/¯

proprietary bad, big corporation bad.

https://www.khronos.org/registry/OpenCL/specs/2.2/pdf/OpenCL_Cxx.pdf
owo what's this

[stiff gull]

Well that took em a while

CUDA had it for years and is likely more matured

wait unless thats the document update date, in that case ignore me

[obsidian bluff]

It says version 2 so it's probably been a thing for a while

nvm that's just the openCL version

It was released in May 2017

[half tusk]

can anyone help me install this

https://github.com/grohsfabian/minecraft-servers-list-lite

[proper gale]

@stiff gull the OpenCL spec is maintained by the khronos group, these are the same people that maintain Vulkan, OpenGL, OpenGL-ES, SYCL, SPIR(-V), WebGL, and more.
These standards also need to be cross vendor which has caused many issues in their design by committee process, result is that it moves slower than others. However, just because its newer doesn't mean its less mature, the people working on these specifications, besides numbering in the hundreds, are looking at current competing APIs/Libraries in an attempt to make the best API they can.
Nvidia does support most OpenCL 2.0 features, and is making an attempt to update their GPUs (they have some issues with SVM afaik), besides their OpenCL resources https://developer.nvidia.com/opencl.

[stiff gull]

@proper gale I know they do support it, but doesn't mean it can match the CUDA speed yet :P

[proper gale]

It's not that slow

[stiff gull]

never said it was slow, its just not as fast as doing it through CUDA :p

I mean, if you're making a bitcoin miner, would you use CUDA or OpenCL for NVIDIA?

the choice is pretty easy

same for anything else that needs performance, and thats basically when you step to GPU compute anyways.

would it be bad to move from python or lua to c++

i like lua cuz you can easily learn it, taking c++ as first language would be pain since you cant just start off using unreal engine easily

[glad terrace]

I'd be willing to bet there are some decent online courses labeled something like "Learn c++ with unreal engine"

[proper gale]

@nocturne galleon you already know lua, or you are considering them both as first languages to learn?

[nocturne galleon]

Hmm, i know Lua but... i hear its hard to move from Lua to C++. I don't know , i hope i can visual script over unreal engine with C++

i dont think random code bashing is good

when i write a line i want it to turn into life visually

[proper gale]

the two languages are very different

almost anything that is automatic in LUA, is manual in C++.

[nocturne galleon]

Well i found roblox which allowes you to easily learn Lua. I wanted to go for Python first but there arent any supported bulletproof engines like unreal engine and unity for it, pygame is long dead so i figured id go with c++ but it takes quite the time to learn the engine before you can do anything

Hm

[proper gale]

the engine is not really the problem, C++ is.

unity is C#, which would be easier.

[nocturne galleon]

i need c++ fur security , well a pen tester told me so id kill 2 flies with one hit or how you say it

game dev and security

Hmm

How easy is the unity engine?

Can i start scripting and learning there or i have to stare at a console for months before i can use it

Its all about making coding enjoyable for me

languages decision is so hard

i been trying to figure out this for 3 years

[proper gale]

@nocturne galleon C++ is not inherantly more secure than C#

[nocturne galleon]

C# yes

[nocturne galleon]

Hmm

If the engine is easier to start with i guss ill try it out

Godot has been mentioned to me but im not sure how long itll last

[keen tapir]

can someone help me with css

[nocturne galleon]

If you learn C# from ground up , you can create amazing games in unity. C# coding gives you a lot of control over unity, which you can use to do whatever you want in your game.

nice to read

and i assume going over to python from c# wouldnt be that hard later? @proper gale

[proper gale]

@nocturne galleon it is not

[nocturne galleon]

Oh alright c# seems t o have the win to avoid any risks

[wheat dock]

we have to use C# for web development in my class right now. its so weird

[haughty owl]

@nocturne galleon The best stuff of learning C# is that you don't limit yourself to Game Development, you can switch easily to UWP, WinForms/WPF, .NET Core and other pretty stuff

[haughty owl]

@last ingot Just saying to him, He has things to win in both sides. C# is greatly modular as it is C++

[proper gale]

@haughty owl i mean, all the languages listed dont limit you to game development. only langs like GLSL and HLSL are limited, but also specialized.

[haughty owl]

They dont limit you per-se, but what effort do you made to code a game with (for example) Ruby rather than C# or C++ is a deal breaker for most people

https://i.marnixbouhuis.nl/images/2019/01/01/68fef32e861441f9807a649bebba44a9.gif

Posted the source real quick to github gist (getting the full chrome plugin onto the google webstore) https://gist.github.com/MarnixBouhuis/9d80eb6033b26359f2a2c1e103c5c685

It automatically zooms in, takes the screenshot and opens a save dialog

Guess someone never heard of the stock market, lol.

Literally all of it is public

[nocturne galleon]

^^^ Plot twist O_o

[glad terrace]

It's not quite the same. The stock market is still private because you still need to pay money to use/have it.

[sullen patio]

[nocturne galleon]

that is not true but ok

its public knowledge

any body know how to convert a system.drawing.color to a hex code?

string color2hex = System.Drawing.ColorTranslator.ToHtml(colorDialog2.Color);

works sometimes but sometimes it returns a color name instead of a hex code

Guess what im building?

[thin cobalt]

Yet another odd issue

I'm doing find and replace in C#, it works fine on small files but on big files it doesnt do anything

        {
            string color1hex = textBox1.Text;
            string color2hex = textBox2.Text;
            string color3hex = textBox3.Text;
            string color4hex = textBox4.Text;
            string str = File.ReadAllText("template.cueprofile");
            str = str.Replace("#ffaaaaaa", color1hex);
            str = str.Replace("#ffbbbbbb", color2hex);
            str = str.Replace("#ffcccccc", color3hex);
            str = str.Replace("#ffdddddd", color4hex);
            File.WriteAllText("generated.cueprofile", str);
        }```

if template.cueprofile is a big file, it just copies it to generated.cueprofile instead of doing the find and replace

[tulip pike]

@nocturne galleon tell us

[nocturne galleon]

@thin cobalt are you sure all the hex codes will always be all lowercase?

[thin cobalt]

Yeah, I made the template file

@nocturne galleon

The file loaded has several thousand lines though

That's probably the problem

[nocturne galleon]

Writing something up for you to use.

[thin cobalt]

thank you

[nocturne galleon]

@thin cobalt

public void Main()
{
    // File parameters
    string originalFilePath = "template.cueprofile";
    string newFilePath = "generated.cueprofile";

    // Fetch the colors from the text boxes
    string color1hex = textBox1.Text;
    string color2hex = textBox2.Text;
    string color3hex = textBox3.Text;
    string color4hex = textBox4.Text;

    // Read the source file
    using (StreamReader reader = new StreamReader(originalFilePath))
    {
        // To write to the destination file
        using (StreamWriter writer = new StreamWriter(newFilePath))
        {
            // Go through each line in the original file
            int lineNo = 0;
            while (!reader.EndOfStream)
            {
                // Read/Replace/Write to new file
                string line = reader.ReadLine();
                writer.WriteLine(ReplaceLine(line, lineNo++, color1hex, color2hex, color3hex, color4hex));
            }
        }
    }
}

// Handles replacement logic
private string ReplaceLine(string line, int lineNo, string hex1, string hex2, string hex3, string hex4)
{
    line = line.Replace("#ffaaaaaa", hex1);
    line = line.Replace("#ffbbbbbb", hex2);
    line = line.Replace("#ffcccccc", hex3);
    line = line.Replace("#ffdddddd", hex4);

   return line;
}

Will work with any file size*

[stiff gull]

@nocturne galleon Will work with any file size hmm I doubt that, seeing as you used an int for line number, there's a reason we usually use size_t (or uint64_t these days), 2.1 billion lines is still a lot but can be done in a 2 GB file

and then it'll overflow to -2.1 billion and crash 😛

[nocturne galleon]

Well, that's why I put an asterisk on the end haha

usually followed up by small print at the end 😛

[nocturne galleon]

I also installed the dark theme that everyone uses

However while using the JFrame builder some colors blend too much, like when changing properties in the JFrame builder

IntelliJ is really the best Java environment

VS Code is alright too

[astral mantle]

its aaaamazing

I use IntelliJ for Python and it's pretty decent.

[spare bison]

Why intellij for Python?

They have a product called PyCharm

[spring radish]

const mockTwats = (str) => {
    const characters = str.split("");

    characters.forEach((char, index) => {
        if (Math.floor((Math.random() * 10) + 1) % 2 === 0) {
            characters[index] = char.toUpperCase();
        } else {
            characters[index] = char.toLowerCase();
        }
    });

    return characters.join("");
};

process.stdout.end(mockTwats(process.argv.slice(2).join(" ")));

Because we all gotta be childish every now and then

This wasn't meant to be effecient or clean

It's literally something I wrote to mock my fiancee a bit 😛

[vestal glen]

I mean, it's a great idea... Though don't proper cool people WrItE aLtErNaTiNg CaPs?

[spring radish]

It's to live up with that spongebob meme

const mockTwats = (str) => {
    const characters = str.split("").map(char => Math.floor((Math.random() * 10) + 1) % 2 === 0 ? char.toUpperCase() : char.toLowerCase());

    return characters.join("");
};

process.stdout.end(mockTwats(process.argv.slice(2).join(" ")));

There, cleaner for you 😛

Well, at that kind of length, might as well change it a bit more

[vestal glen]

almost a "one liner" 😉

[spring radish]

const mockTwats = (str) => {
    return str.split("").map(char => Math.floor(Math.random()) % 2 === 0 ? char.toUpperCase() : char.toLowerCase()).join("");
};

process.stdout.end(mockTwats(process.argv.slice(2).join(" ")));

Just a little past the 80 character limit so I'll let it slide

[vestal glen]

hm, didn't you break your Math.random though?

[spring radish]

I did

[vestal glen]

wouldn't you have to Math.round() to have a 50/50-ish chance?

[spring radish]

Math.round or add a * 2

Math.round seems cleaner

so that's what I changed it to

const mockTwats = (str) => {
    return str.split("").map(char => Math.round(Math.random()) % 2 === 0 ? char.toUpperCase() : char.toLowerCase()).join("");
};

process.stdout.end(mockTwats(process.argv.slice(2).join(" ")));

God I need better things to do than this...

    return str.split("")
              .map((char, index) => !isRegularCharacter(char) ? char : index % 2 === 0 ? char.toUpperCase() : char.toLowerCase())
              .join("");
};

process.stdout.end(mock(process.argv.slice(2).join(" ")));

No longer breaks on special characters such as '

[supple abyss]

hi, I am reading through a pdf about "modell languages" (in correlation to the turing machine, finite state machine etc.) and I dont know what the succ is supposed to mean (not in the meme way pls)

also dont understand where the Z comes from and the B is never found. I'm guessing the prof. made a mistake?

also translated this means WHILE-language: addition/sum

[ember kiln]

succ(x) (usually) means successor of x, which is x+1

looping on WHILE succ(z) <= b is equivalent to WHILE z < b, and off the top of my head I can't think why it would be easier to do the former in a Turing machine either, but if it's an intermediate language then it might fit better with the model

the z is initialised to 0 before the loop, and is a count of what has been added so far; the loop runs until z=b, at which point you have finished adding b to x

Can't get this stuff to center

[verbal otter]

how put the code in those blocks?

[spring radish]

If you just something like this then you just wrap it in `

one on each side

now, if you want code formatting you put ``` on the first line and the last line

the top line, immediately after the ``` you can put a language down like js, html, markdown, and like 90 others to get syntax highlighting

like so

const someCode = () => {
    return 'some string':
};

In my text field this looks like
```js

const someCode = () => {
    return 'some string':
};

```

[lapis granite]

@spring radish flexbox maybe?

[vestal glen]

(based on the text going out of the purple box this seems like images + text to me?)

[spring radish]

The purple is a image that’s repeated over and over again to create. Background

That’s on the body element

The text is a h1 inside header, inside a div

Now, none of those elements have any margin, width, or padding

They all set width to 100% of the screen

Now, no matter where I place text-align:center or margin-left: auto;margin-right: auto; or boy

Both•

It produces that result you see on the screen

@jade rain what compiler?

visual studio obviously

[proper gale]

thats the IDE

[round dome]

. . . . .

[proper gale]

that follows part of both MSVC and GCC ASM syntax, and MSVS can use GCC

assuming MSVC, his original code is mostly syntactically

cant believe i didnt spot the semicolons on each line

but to be fair, i dont know ASM syntax rules for inlining, as i never do it. can read the stuff though.

[round dome]

well first he uses the MSVC keyword, and then in his screenshot uses the GCC keyword...

[proper gale]

which is why i questioned what compiler

[round dome]

yes but you didn't get my joke :'(

[proper gale]

what joke?

[proper gale]

multiple people i know thought (or still do, idfk) that Visual Studio and MSVC are just different names for the same thing.

[round dome]

[jade rain]

Using VS as both

[proper gale]

^ see

@round dome

[round dome]

your assignment expects you to use GCC apparently, aren't you supposed to work on a linux kerneled environment ?

[proper gale]

oh, huh, that is GCC ASM syntax

just download VSCode and make sure you have GCC set up @jade rain

@craggy acorn start with any language, do not focus on games right now. As soon as you start understanding how languages works and basic programing you should start making games ( that will take you a few months to a year ). Don't rush things because that is how we get crappy devs

^ the real answer

[ionic hull]

Stop shitting on php ffs

PHP 7 is really good and if you are an experienced dev you won't make any basic PHP errors

[ember kiln]

PHP is better than it used to be, but it's far too inconsistent (and far too easy to make mistakes) to be considered a good language

See also http://phpsadness.com/

@last ingot I am a web developer, I do freelance and most often I use the php stack. And php isn't a bad language, you just need to be really careful when using it. PHP has a bad name because of the half assed apps that are running rn. And when you use the term "kid" you just show arrogance and most often who says that is a kid himself

@last ingot to answer your question of what I want to make is a Log book system for my community

What would you suggest I build this project on then? If not PHP?

[vestal glen]

(some language/framework you're comfortable in)

[proper gale]

@last ingot that may be stupidest logic ive ever heard.

good amount of my own code, its a black box, i know what it does, and generally how, no idea how to fix it without re-reading everything.

nobody can keep an entire codebase in their head.

If i coded it their wouldn't be any errors :P and if their was i would know how to fix it because i would know the codebase. <- what im talking about

you will make errors, you are human (i think), and you wont know how to fix them any better than if someone else wrote the code if you didn't write it yesterday (figuratively)

yes it is If i coded it their wouldn't be any errors

so you are saying that its easier to work with a code base you have been working with vs something that you have never seen before, no shit

you used C++?

it will fail, and not tell you anything

C++ wont in debugging

unless you are using valgrind, and then it may

ok, that a debugging technique, because the language tells you jack shit.

you ever read a template compile error?

segfaults are fun, but debuggers are not complete shit at finding where that happened.
the real fun one is a memory leak.

i never said anything about an IDE

was talking about libraries i wrote, that were for a game engine, but thats not what im using them for.

i actually need to go over my config one, as i switched to a different object style, and it would be real nice if it used that.

for what?

what data?

salted hash

i would recommend the SHA512, SHA-3, or Blake2b algorithms.

yes

wait, no.

hashing is not encryption

you take the password, run it through the hashing algorithm with a unique salt, and compare the result.

you store the hashed password and salt.

that is exactly what i just said to do

and i have you one way hahsing algorithms.

one way hash with salt

@mossy ice lmao that’s so funny

[zealous kayak]

GUYS .. react or vue?

[nocturne galleon]

@zealous kayak my vote is for React

[kind portal]

hey, what is an ArrayList in java?

[grand hornet]

Java has ArrayList too

@zealous kayak I would use Vue

How did “Linus” steal his OWN 🧠. With 💴 and “brand power”

I don’t get “triggered” “doctors” got my 🧠 “messed” up by 2 💊 the “doc” gave me.

[proper gale]

@kind portal an array that can change size, based on a normal array that it manages.

[shrewd sequoia]

So is anyone here familiar with ROS?

[dark thicket]

robot operating system

[nocturne galleon]

Something like Alexa?

[thin cobalt]

anybody here good at C# winforms?
I have a question

i have a ListBox, and I want to add items to the listbox from another class

how do I do that?

[thin cobalt]

I want to be able to do listBox1.Items.Add("some log message");

but from a different file

[nocturne galleon]

hey @proper gale about that video on storing passwords, when talking about the hashing and salting. how do they decrypt the password for when they need to check it against what the user enters?

[ionic hull]

@nocturne galleon when the user enters the password, the code behind the login will get the hashed password stored in a database or whatever, then hash the password that the user gave. And just simply check if the hashes are the same

[nocturne galleon]

But if the password is salted wouldn’t it be a different hash?

[ionic hull]

Example:

md5( password + "some key")

The hash will be the sane

Same

[nocturne galleon]

@thin cobalt can you just put a static method on the class that the listbox is local to and call it from the other class?

[small escarp]

probably not static

also, @nocturne galleon the test is hash(user_input + known_salt) == stored_hash

note that both stored_hash and known_salt are stored in the user row in the database

and will be different for each user

the salt is not particularly secret, since a hacker who has access to the db can read it in cleartext

it's only to ensure everyone has effectively a unique password

[hasty portal]

wrinkly

[edgy ferry]

im clueless in blender

[proper gale]

@hasty portal what is that, and why did you make it?

[hasty portal]

idk bored

[rigid jewel]

blender is great!

Hey question I know you can cluster raspberrypi CPU together but can you also cluster the GPUs? What I would like to make is a mobile retro mobile console that can do things like psp and Nintendo ds by clustering 2-4 pi zeros together in the hopes of combining the GPU power of all of them, then running retropi. Is this possible?

[rigid jewel]

@solemn spade i highly doubt you will get the kind of performance you are looking for, Pi Clustering really kind of sucks

its more for learning, than for practical use cases

[solemn spade]

Welp it was just a thought....

[rigid jewel]

you would be just better of using a Pi 3 B+

[solemn spade]

It’s not powerful enough to do psp and ds really

[rigid jewel]

sure it is

[solemn spade]

I’ve tried

[rigid jewel]

i run RetroPi on mine, i was playing Ps2 games even

[solemn spade]

Ya “some” of them I want all games to work

I have a pi 3 b+ and it has a hard time playing psp and n64 and ps1

[rigid jewel]

you were using RetroPi ?

[solemn spade]

Yes

There image even

The new one 4.4

[rigid jewel]

well the Pi Zero is far less powerful than the 3B

even 2 of them would not be as fast

[solemn spade]

Well from what I’ve notice the CPU is like never the issue even on my pi zero but the GPU is the bottleneck
