Server has secret, hmac the cookie with your secret, check hmac matches, if so, cookie is good. Store a session id in the cookie

If you want you can include source ip as part of that session and check that it matches. You can also include an expiry. It cant be modified since the hmac wouldn't match anymore

And if sever side you want to de auth you just delete the session from the db

If you aren't comfortable with that use a library doing this all for you.

And dont check your secrets into version control

[native shoal]

I just dont get why it warrants being put there in the list of issues... just to keep the known issues area populated with something

That is literally the only reason.

uhhh

ty for the reminder to search my vs installation on my old boot drive 👀

but i can't help ya sry

[nocturne galleon]

im so lazy, i keep telling myself to learn c++ but I just never do it

[nocturne galleon]

yeah i am gonna do a little project to learn

but i wanna get the fundemental syntax down first

[zealous kayak]

Guys .. Adonis OR Express? and why :\

[ionic hull]

Isn't express more main stream? Always use main stream

[main root]

value = 5
if(int(someEntry.get()) == value):
print("Something")
else:
print("else")

if i type in 5, then it always goes into the else block 👀

wtf im doing wrong

[plush pollen]

is that python?

[tropic grail]

@main root someEntry.get() != 5

[main root]

ye python

if i type != value it jumps into the if block
if i type > value
it jumps into the if block too
so apparently 5 > 5

(if i type 5 into the entry field)

its some logic error

[woven flower]

python is fun

my discord bot is written in python, so if you have logic questions hmu

[main root]

idk how useful the gui stuff in python is but its my first real try doing something with a gui

ignoring webstuff 👀

[woven flower]

i mean there's prolly a ton of different GUI libraries

only one I've ever used, BARELY is Tkinter which was... weird

[main root]

tkinter is that little guy 🤔

[jolly pelican]

I didn't like any of the more native python GUI libraries

They all kinda sucked

Could try GTK bindings though

[grizzled kite]

Is anyone here good with HTML?

[median spire]

@grizzled kite what'ca got?

[grizzled kite]

Trying to make a header, but got this https://i.imgur.com/P3wVvw9.png
I want all of the items on the same line

I tried using display: inline but it didnt work

https://i.imgur.com/4sknJKG.png

[median spire]

You are going to want to use display: inline on each element additionally it helps to define the width of each element with width=15% or something similar

[grizzled kite]

hmm ok

[median spire]

<div> is a block element, anytime you use it it will create a new line, you can tell it not too. you can also try having your entire banner in one div so that it doesn't break like that.

<span> is similar to <div> but without the line break and might also be usefull to you

this page explaines it pretty well:

https://codeburst.io/block-level-and-inline-elements-the-difference-between-div-and-span-2f8502c1f95b

[main root]

oh and also

<header></header> is a thing

idk when that stuff got introduced but
<header>
<nav>
<footer>

just make it easier to read

[cold oar]

question

why is it that when you buy a software

you are not allowed to modify or copy it.

I think thats a stupid thing

because, you paid for the software

its your code now

i dont understand this logic

when you buy a car you can do whatever you want with it.

[turbid delta]

sadly many publishers say that you don't really buy there software rather you buy there rights (license) to use it. therefore your not allowed to modify or copy it.

[cold oar]

its stupid

[turbid delta]

well i cant agree more with you xD
but that's how this world has become
i can understand the companies that do this to some extent as many people that modify the Software claim that its buggy or is unusable in order to harm or take advantage of the company.
And think of the persons / customers that use the software and install modifications and start finding bugs that are not inside the original version. That would make a support team struggle to explain what's going on.
i hope that's helpful to you @cold oar

[next flax]

yea, in that analogy it's kind of like assuming buying a car meant it came with all of the r&d materials, schematics, etc to build it

food doesnt come with the recipe to recreate it

[cold oar]

Well this will never make sense to me...
I think my explanation with a car is pretty accurate.
You get a copy of a software that is already made that you don't have any knowledge of on how to modify it.
Same as with a car,
You get a replica of a car that you have no knowledge of on how to modify it.
Same thing.
Then why can you resell the car but not the software...

[nocturne galleon]

Not sure why you should feel entitled to get the source code just because you bought the software. If that were the case, all software companies would go out of business. 🤦

[little knoll]

The "you can modify your car how you want but not the software that I paid" thing doesn't work if the software is offering you an API or a plug-in SDK. In that case, you effectively have the possibility to modify the software.

And even if you don't, well the contract you accepted when you bought your software is telling you anyways that you can't. If you don't agree to it, then don't buy it.

[novel spear]

its very unlikely having read access to source code would cause a company to go out of business

they still have patent protection and copyright on the code

and anyone who really wants to can figure out what a compiled binary is doing if they want to steal its secrets

unless its SAAS, its unlikely it would be an issue

[next flax]

releasing source can be a huge headache; most major closed source software you use probably has lots of variably licensed bits inside it, the legal hoops they'd have to jump through to release it may be insurmountable

[novel spear]

yea, thats the main reason companies dont do it

[next flax]

and even if they are surmountable, why bother? it's easier to just.. not

[novel spear]

it has very little benefit to them and costs money and time and legal exposure

but it wouldnt cause them to go under or anything

unless its SAAS, then the service nobody could reverse engineer

[next flax]

i'd really like to open source the stuff at my day job, but it's not practical until we start building stuff against a whole new stack -- one freshly engineered with being open sourced in mind

[novel spear]

then there is a big argument

yea thats the third problem

if you license an ip which doesnt let you open source

and even if you dont, it limits options down the road

but also many of these companies just slap a "you agree not to reverse engineer this" then pack the binary and call it a day on their binaries

although in some countries those legal protections dont apply in some cases, like in Canada you can reverse engineer for the purposes of compatibility

like an old game which doesnt run on newer windows

but its unclear if you can legally publish your findings

or what "compatibility" means hasnt been tested in court

[novel spear]

A lot of big known stuff is either black box reverse engineering or clean room reverse engineering

and potentially before DMCA

or not from the USA

[nocturne galleon]

There's many reasons it would cause immense harm to a business. I don't have the energy right now to explain all of them though. I'm sure if you think about it, you can come up with a lot of reasons.

Need some help, in the log it logs numbers correctly and the servers, icons and names array are populated when I log them. When I hard code the number to for example 1 so it becomes: {{servers.[1]}} it works fine. Logging {{@index}} works fine, but logging the arrays with @index as number doesn't work. Having that console.log to look why it doesn't write the <a> tags correctly

{{#ifEqualOrHigher servers.length 1}}
    <h2>The bot is in {{servers.length}} servers where you have Manage Server permission.</h2>
    {{#each servers}}
      <script>
        console.log(`{{@index}} - {{servers.[@index]}} - {{icons.[@index]}} - {{names.[@index]}}`)

Does anyone have any recommendations for a second hand laptop under £500 that has a 1080p screen, decent processor (maybe 8th gen Intel or a quad core Ryzen) and at least 8GB ram? I'm hoping that laptops from a couple of years ago can now be found much more cheaply but I'm not sure what to even look for. I'm a Web developer working full stack in both ASP.Net Core C# stack and Node.js stack simultaneously with frontend JS frameworks thrown in too so I'm not exactly a light user. Any advice would be greatly appreciated!

[spring radish]

Anyone know the name of this practice

Boolean ? true : false;

And if lua have an eqv of it?

[proper gale]

being stupid? see previous answer because lua.

[spring radish]

...

There's no need to be an arse about things

To anyone else that might be interested in what it's called. Ternary and lua's eqv is ```lua
Condition and "result if true" or "result if false"

[proper gale]

oh, i thought you meaning using it actually as condition ? true : false; not what the structure is called.

ive seen code like that because reasons

i also dont like lua, at all

[nocturne galleon]

nvm figured it out

[bright hazel]

Hmm development. Does this also Count for coding ?

[woven flower]

yes indeed @bright hazel

[bright hazel]

Nice :). I am a php scripter and Made a script but I need Some one to test something out xd

In short. I created a filehost script That works with x-sendfile. Added a bit of code to iT so I can show the file as. Preview ( like mp3 Or video. All html5 stuff )
But I need to know If a timeframe of 5 seconde is enough to bypass the download protection

On iPhone iT works ( movie of 3gb can be watched ). But I do not know If iT works for pc. I mean If the video need to be started before iT sinds the code to the server Or That iT cach iT On load ?

Sorry for bad typing. iPhone autocorrects

To give a idea. This is the code for the file

<source src='./{$link}/{$tscheck}' type='video/mp4'>

[median spire]

are you trying to avoid triggering the download protection in web browsers?

[bright hazel]

Or In short. I am just looking for a kind of hot link protection

No. I got a download button users need to press to download the files

As those files are stored outside www folder. And I do not want them to hotlink them

A link looks like this. Website/code. Download happens with same link but with a post request so they can not directly link them

To let the video tags work I need to hotlink the file else it won’t load ( also because they are stored with out extension ) But I do not want it that users are able to share that code or to bypass the countdown counter

The problem is that I do not know if a video tag to the file with a time limit of 5 seconds is enough. Or that a user need to interact first before the “streaming” starts

[bright hazel]

Or that there is. a other way to prevent hotlinking

[limpid reef]

Um... you would use htaccess (if on an apache or litespeed webserver; I'm sure nginx has an equivalent) to enable hotlink protection @bright hazel https://mediatemple.net/community/products/dv/204644230/prevent-hotlinking-with-a-htaccess-file

[bright hazel]

@limpid reef thank you , but htaccess wont do the trick this time , as it downloads the file that is outside public html, so a external file need to be called, that file is also used to serve normal downloads

in meantime i solved the problem i think

$domain = parse_url($http_origin, PHP_URL_HOST);
$domain = str_replace('www.','',$domain);
$allowed_domains = array(
  'dir.nu',
);
if (!in_array($domain, $allowed_domains))
{
             
            exit;
}```

[nocturne galleon]

do you guys like how I write my issues?

yeah it's just for lols

[odd cypress]

I would exclude "I can't believe he [...] what I want". Just start with "The program gets a fatal exception..." However I like to see the use of code blocks. 😉

[proper gale]

i mean, this case its not that horrid, you can clearly see that the call to widget is where the error occurs, so its the call before returning NoneType

now imagine if it was an index out of bouds, that could be anywhere

[proud ermine]

hi there, just wondering if anyone here has done some sort of openssl programming? I ran into some issues with my rsa implementation using openssl for Intel SGX and the message doesn't seem to be decrypted in Enclave, it always says the padding error and I have noticed that it will always fail to decrypt as long as there is 0x00 inside the cipher text

[mellow hound]

https://scratch.mit.edu/projects/131389770/

my epic code

[woven flower]

[proper gale]

@proud ermine if you were using CryptoPP i could actually help you with that

[proud ermine]

@proper gale i need to use openssl because of its intel sgx support.

[proper gale]

What do you need sgx for?

[proud ermine]

it's a experimental project from my uni

but my problem is when decrypting cipher it says padding error and i noticed that it will definitely fail to decrypt when "0x00" exists within the cipher

i've written two different versions of rsa implementation, one from openssl and another one from intel-sgx-ssl implementation

intel-sgx-ssl implementation fails to consume the cipher with "0x00" and openssl does not

[nocturne galleon]

GUESS WHOS AN IDIOT

ME

i spent the last 2 days trying to fix 'NoneType' object has no attribute 'widget' without realising that the function i call it in literally removes that widget 1 line before it's called

flutter? @nocturne galleon

[nocturne galleon]

yeah

atleast i think that's what it was, i haven't actually tried yet

there we go

now i can finally close that issue and move on

[bright hazel]

can you send headers from inside a class ?

class Header
{
 public function Gone(){
            header("Cache-Control: no-store");
            header("HTTP/1.1 410 Gone", TRUE, 410);
            exit;
}
} ```

or should i use return instead ?

[deep scarab]

you might want to learn to code first before doing whatever you're doing

[bright hazel]

already solved

but this is just strange

let me trow in the code ... so you can see

$bind = array(":link" =>$link);
$control = $db->select("files", "link = :link", "", $bind, "fetch");
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "https://{$control['host']}/ajax/check.php?check=download&download={$link}");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$output = curl_exec($curl);
curl_close($curl);
$output = $output?$output:"404 Not Found";

i got this exact same code in a header file that get included , it shows the stuff i need , but in my other page it does not get the string value even it does show it in var_dump

if ($output == "virus")

 public function Check($link)
            {
            $bind = array(":link" =>$link);
            $control = $this->db->select("files", "link = :link", "", $bind, "fetch");
            $exist =  file_exists(Config::DOWNLOAD.'/'.$link);
            if ($exist AND $control){
            return "Download {$control['file']} now from fileshare.site";
            }
            elseif (!$exist AND $control)
            {
                return "virus";
            }
            else
            {
                return FALSE;
            }
            } 

and because you ask it so nice, to make the code complete

switch ($check)
{
    case "download":
    echo $checkfile->Check($download);
    break;
}

also @deep scarab , i am writing a download script , so far it works , now i just need to get my multiserver check to work 😄

return value is this => string(7) "virus" , header file takes it as it sets it as title like it need to be , but the script does not get the variable to use as check, why does it do that ?

nvm , it seems that curl provide a whitespace or whitetab for some reason ... it shoulnd do that 😦

what do you guys use for getting time intervals in cpp? like for a function? @proper gale

[proper gale]

what do you mean time interval?

@vernal marsh

[vernal marsh]

yeah

I tried using std::chrono but somehow I am getting 1001067ms for running a function lol @proper gale

1001.067 seconds that is Lol

https://tenor.com/view/happy-molang-strawberry-sparkle-excited-gif-12390194

[proper gale]

how are you measuring it?

[vernal marsh]

int main()
{
    const int arraySize = 5;
    const int a[arraySize] = { 1, 2, 3, 4, 5 };
    const int b[arraySize] = { 10, 20, 30, 40, 50 };
    int c[arraySize] = { 0 };

    // Add vectors in parallel.
    auto starttime = chrono::high_resolution_clock::now();
    cudaError_t cudaStatus = addWithCuda(c, a, b, arraySize);
    if (cudaStatus != cudaSuccess) {
        fprintf(stderr, "addWithCuda failed!");
        return 1;
    }

    printf("{1,2,3,4,5} + {10,20,30,40,50} = {%d,%d,%d,%d,%d}\n",
        c[0], c[1], c[2], c[3], c[4]);

    // cudaDeviceReset must be called before exiting in order for profiling and
    // tracing tools such as Nsight and Visual Profiler to show complete traces.
    auto endtime = chrono::high_resolution_clock::now();

    auto totaltime = endtime - starttime;
    cout << "totalTime : " << totaltime / chrono::microseconds(1) << endl;
    cudaStatus = cudaDeviceReset();
    if (cudaStatus != cudaSuccess) {
        fprintf(stderr, "cudaDeviceReset failed!");
        return 1;
    }

    return 0;
}```

that's cuda project template's main funtion.. and that's how I did it

[proper gale]

is it taking 16 minutes for that function to run?

[vernal marsh]

nope lol not even a second

simple vector addition that is

[proper gale]

if the answer is no, thats because its actually in ns when you get it.

[vernal marsh]

aaaahh but why ..

I am dividing it by microseconds 😕

[proper gale]

thats, not how that works

when changing from anything to anything else, use std::chrono::duration_cast https://en.cppreference.com/w/cpp/chrono/duration/duration_cast

also, high_resolution_clock is shitting out nanoseconds

assuming you are x86 linux or windows, its technically implementation defined and can be different but ns is the most common

what do you want your output in, microseconds?

[vernal marsh]

ye

oooh.. is there any other way to get time intervals? I just want to verify

[proper gale]

std::cout << "total time : " << std::chrono::duration_cast<std::chrono::microseconds>(totaltime).count() << std::endl;

besides system specific ways that is how std::chrono is, not really.

besides, std::chrono is fine, and is very accurate if used correctly.

[vernal marsh]

thanks @proper gale I will just check that..

@proper gale

aaaa what?

cuda profiler says 0.3 ms for application level after a few launches

and chrono almost comes near 0.4

@proper gale

    std::chrono::duration<double> totaltime = endtime - starttime;
    std::cout << "total time : " << totaltime.count() << std::endl;

this worked

I still wonder why didn't that work

[proper gale]

you realize that cuda.exe is .28 seconds, or 280ms, right?

they aren't measuring the same thing

[vernal marsh]

I think its just measureing kernel time ryt?

[proper gale]

no

no, thats not at all what its measuring

[vernal marsh]

oo its the entire applicatoin

[proper gale]

and then some

[vernal marsh]

soory I read that 0.28 ms

[mortal lagoon]

I've been wanting to write my own fan controlling program in C to optimally use a touch screen i got my hands on. Does anyone know how to interact with the PWM chip on the motherboard?

[next flax]

if you are trying to measure gpu time you need to force cuda to block/sync

or iirc cuda has native timing stuff

https://devblogs.nvidia.com/how-implement-performance-metrics-cuda-cc/

you should use nsight tho, not just the overall trace timing, it has really precise timing/perf metrics

[vernal marsh]

nsight is good for kernel timings and memory debugging in gpu as other tools doesn't have access to those things

I was just wondering about doing it programmatically ... I knew I could use VS's debugger and just breakpointed before the function and just run that... this would have also given me the timing

LOL yesterday I think I just looked the timing 0.28 and just assumed it in ms and further considered it as kernel time as.. the function coming just above that 😛

I'll try.

didn't work.

one moment

it doesn't completely crash now but now it won't test for the variable?

I uh

I am ashamed to say

it was my messy quotations

in line 66 I opened and closed quotations in my declaration of the delete variable (in the user prompt text) and then the (y/n) closed the if statement prematurely, causing it to read the = " as a new command completely breaking the script

no worries :) glad it works!

I went back to my testing project last time to check on the cudaEventElapsedTime

only lead I have is.. this might be running on gpu instead of that might result in delay

[next flax]

what do you mean "changing" ?

the times are different because they are tracking different things

the cpu-side one is probably just checking how long it takes to tell the gpu to do something, not timing how long doing that thing actually takes

you can't really time graphics/compute stuff by taking cpu timers

unless you force the gpu/cpu to sync up a lot

[inner wraith]

For some reason I have a snippet of code that only sometimes is a syntax error in Python, but then nothing changes and it works. Same Python version for all occurrences and it's driving me nuts.

class easy_deploy:
    def __init__(self,
        routeros_packages: dict,
        firmware_version: str,
        firmware_local_path: str,
        firmware_path: str,
        <more of the same>
    ):

The line with routeros_packages: dict, occasionally throws a syntax error.

Python 3.7.3

This happens when loading the file... sometimes... But not other times. I can't think of a sane reason why this would occur.

[inner wraith]

It's freaking out over the variable annotations.

But... only sometimes, and only in VS Code, same interpreter started from a shell works fine.

I've checked VS Code is using 3.7.3.

[spring radish]

Anyone got any suggestions/solutions for tracking changes in large files

git LFS wasn’t a solution that worked

The final repo size was too big

[stray acorn]

How big are you talking about?

[nocturne galleon]

ok now im just confused. i have 3 python files, 2 of them access a list in the third, the problem is, the first file can see the list and its contents, but when I try and print the contents of it or do anything with it through the second file, it thinks it's empty, no runtime error or anything

[spring radish]

@stray acorn it’s about 5600 files or so total to be tracked, the biggest ones being 35mb a pop

[next flax]

svn/perforce are common at game studios, where many/large binaries are important

(terabytes sometimes!)

What's the best way to detect if a message contains a password?

It's for my discord bot to delete the message if the user sends a password in their message

[vast echo]

seems like a hard thing to do without having a list of passwords

the only thing I can think of is blacklisting the phrases: "my password is" or "the password is"

[deep scarab]

yeah, how would you differentiate a password from just a normal word?

if the user just has a randomly generated password, how would that be any different from someone smashing random keys on their keyboard

wtf

[fervent thicket]

if i got a variable that gives back an array of text, and the total of those array together is more than 2k what can i make so it stores it in someway or form in batches below 2k characters

[nocturne galleon]

@fervent thicket Would help to know what language, and what you mean by "batches below 2k characters"

[fervent thicket]

Sorry i wrote that when i was pretty tired and slept after

Its in javascript, for a discord bot using discord.js

[nocturne galleon]

Ok, so you have 1 array with a single string of 2k characters or 2k different strings in an array?

And what do you want as the end result?

[fervent thicket]

Well I got one string that is over 2k characters

What I want it to do is for the bot to check if the string is longer than say like 1950 characters or such cut it and send the first half then the second etc.. until it is all sent

I can share my code if you that helps?

let emojiList = message.guild.emojis.map((e, x) => (`\`${x}\`` + " = " + e) + " | " +e.name)

  message.channel.send(emojiList)```

[nocturne galleon]

Instead of mapping into a string, do a for each into an array of strings.

Then loop through all your array items and build out a single string message

Inside the loop, if you're message is greater than 2k characters, then post it.

At the end of the loop, post your message.

I'm out at the moment but when I get back I can write it out.

[hazy bobcat]

So I want to do 3 things in this project of mine. Basically it's a mod manager in Python that just installs mods however the 3 steps I want to get done are a bit circling me.

1. have a list of MD5's and have a for loop check if either the files extracted or the ZIP equals a md5 hash or whatever hash is better in them
2. check if the filename of the zip such as development-1.1.1-mod for a list of words and if it finds a exact word in it, to report true else false so if I wanted the development word flagged, I would want to get it out of the file name of the ZIP.
3. hide said code in a existing py with a obscure important name to avoid people trying to reverse engineer it

Thing is that several mods are banned from the main hub and people are still distributing it so I would like it to NOT be used for those mods and hopefully get others who have the same idea as mine that don't have it to enforce said policy

I know the md5 import but unsure on actually making a define or class to be called in the middle of it

[nocturne galleon]

@fervent thicket

// Fixed number for message length
const maxMessageLength = 1950;

// Store our running length as we post the messages
var messageLength = 0;
var msg = "";

// Loop through all our emojis
msg.guild.emojis.forEach((emoji, i) => {
    // Build out the string we will add to our message
    var newEmoji = (`\`${i}\`` + " = " + emoji) + " | " + emoji.name + "\n";
    let newEmojiLength = newEmoji.length;
    
    // If our message will exceed 2000 characters, 
    // then we need to send it before we add this to our message
    if (messageLength + newEmojiLength > maxMessageLength) {
        message.channel.send(msg);
        
        // Reset for next message
        messageLength = 0;
        msg = "";
    } else {
        // Add to the message and carry on
        msg += newEmoji;
        messageLength += newEmojiLength;
    }
});

// If we have a message to send at the end
if (messageLength > 0) {
    message.channel.send(msg);
} else {
    message.channel.send("No emojis! :sad:"); 
}

[fervent thicket]

@nocturne galleon oh wow! Thank you! the variable emojiList does bring back a array of strings etc.. unless i .join(" ") them, ill tey your code ^^ :D momento

it works! Holy crap! Thank you so much :D

[nocturne galleon]

@fervent thicket of course, enjoy

[nocturne galleon]

@fervent thicket just reread it. You'll want to take the contents of the else block outside of the if statement because you'll miss that 1 emoji if it sends the blocked message

Hi I’m new here and unsure who to talk to so...I think I have a solution to ransomeware

My laptop was infected a while back and I got rid of it easily

[novel spear]

Typical ransomeware encrypts files so the only solution to getting rid of it is a restore from backup

Because encrypted files can not be recovered without the key

[proper gale]

@spring musk they are declared, not assigned. and have you gone over arrays yet?

If you have ransomware, call the local Police station NON-EMERGENCY line. They should be able to remove familiar types of ransomware from your PC.

DO NOT CALL 911 over this.

I have a Game Development opportunity available. We are basically making Star Wars Battlefront 2 2005. There is currently no pay as we are working on the demo to submit for funding.
What we have:
Many developers with programming, modding & other experiences. We already have the game networked online with selectable classes & enterable tanks.

What we need: More programmers
If you're interested, complete the following lessons:
https://www.codecademy.com/learn/learn-git
https://www.codecademy.com/learn/learn-java
Following this, there must be pre-existing examples of Unity projects or completion of:
https://learn.unity.com/tutorial/survival-shooter-training-day-phases?projectId=5c514921edbc2a002069465e#

Finally, submit a demo with the Mirror API obtained from the Asset store in Unity 2019.3's newest edition. Documentation available here:
https://mirror-networking.com/xmldocs/

These are the pre-requisites because you'll need to know these things on a daily basis.

Age, sex, & experience doesn't matter. We want drive to work in a structured team. PM me if interested.

FAQ:
I know Java...
It'll take you no time to complete that short lesson then.
What's the pay?
We don't have pay right now. We're searching for funding after we develop a more complete prototype.

java+unity ?

[nocturne galleon]

@next flax Java is similar enough to C#. I need people to understand OOP.
@last ingot no.

I’m not about to have a language debate.

Yes. It's a cross platform language designed to be usable by C++ and Java programmers. I know. I've been using it for 5 years.

What's your point?
I want people to understand OOP principles so I gave them a lesson that teaches that.

Okay?

[next flax]

not debating which language(s) you should use, but if you're trying to get people with that little experience in, you should probably find lessons to match the language

if they are really really new to programming they will be struggling enough with it, don't add in transferring concepts between languages

[nocturne galleon]

@next flax I'm requesting anyone & everyone. If they're new to programming, this will get them up to speed rather quickly. Most of Java's core syntax is exactly the same as C#. When they do the Unity Tutorial, they'll learn C# but have a good deep understanding of the design structure. Syntax is nothing.

does anyone here use python?

need some help dealing with datetime

[woven flower]

sure what's up

I've done a little bit of datetime stuff

[manic plover]

i'm getting a value from database as a datetime.deltatime object, is there anyway I can convert it easily into a datetime.time object?

[woven flower]

deltatime is an amount of time between two measurements, yeah?

[manic plover]

yeah

so the deltatime object actually has the time of day

[woven flower]

I'm not sure what you mean by converting that back to a time object, since isn't it inherently mostly like an integer/value?

hmm ok

[manic plover]

but the ORM i have is returning it as deltatime

[woven flower]

so like a time elapsed from midnight for the date or something?

[manic plover]

yeah time from midnight

[woven flower]

ok and you're trying to turn that distance from midnight into the actual current time object?

[manic plover]

yep

i already tried time.mid + deltatime

[woven flower]

hmmmm. cause that was gonna be my guess
iirc you can just add deltatime to a datetime.time object and it just work™

or that's how it's supposed to go

[manic plover]

that gave me an error saying unsupported operand '+' for time and deltatime

[woven flower]

hmmm

there's a way to add those together but I can't remember it off the top of my head

lemme do some research

so apparently there's a method to go about this

there's no native "datetime.time + deltatime" support which seems odd

but you can combine a datetime.time object with a deltatime using datetime.combine

[manic plover]

oh cool

i'll try that

    Microsoft® Windows® 7/8/10 (32- or 64-bit)

    The Android Emulator only supports 64-bit Windows (learn more).
    4 GB RAM minimum, 8 GB RAM recommended
    2 GB of available disk space minimum,

    1280 x 800 minimum screen resolution

[quasi plover]

i'm using linux

[manic plover]

Linux

    GNOME or KDE desktop

    Tested on Ubuntu® 14.04 LTS, Trusty Tahr (64-bit distribution capable of running 32-bit applications)

    2 GB of available disk space minimum,
    4 GB Recommended (500 MB for IDE + 1.5 GB for Android SDK and emulator system image)
    1280 x 800 minimum screen resolution

basically the same thing

[quasi plover]

cool so no 2gb ram

that's some extra 20$

[manic plover]

i'd suggest a minimum of 8GB tho

unless you can bare with a particularly slow experience

[quasi plover]

well i'll see i can still upgrade tho it has 2 ram slots i'll try 4gb if it's slow then i'll try 8

which means more money

damn

[quasi plover]

manjaro is way better it has AUR and blackarch repos + you can install .deb files in it

and with the deepin envirenment you i'll be stunned with it's looks

Hi everyone. I don't know if this is the correct place for this but anyways. As you may know Valve has released a modified Wine, which is called Proton (Steam Proton) for gaming on Linux. But It still has flaws. There is one problem we are trying to solve here : https://askubuntu.com/questions/1169612/how-to-lock-mouse-cursor-to-the-middle-of-the-screen-18-04

and also link to the issue at github : https://github.com/ValveSoftware/Proton/issues/579

Basically, (although not always) whenever you alt-tab from game and alt-tab back to the game, game behaves like as if there is a cursor on the background and when you try to look around, you just can't after a certain angle. Because cursor hits the screen border, there is no more room for it to go.

Anyone has any idea how to fix this, or find a way around?

This is a huge problem specially in FPS games (or basically any games where you have crosshair). Also in strategy games, since you can't move camera around by just moving your in-game cursor to screen borders (I guess It recognizes it as a desktop cursor, I dunno).

[next flax]

fix as like an end user?

as a hack workaround can you run a script that just constantly sets the mouse to the center or something?

i think this can set the mouse position https://linux.die.net/man/7/xautomation

[snow harbor]

we have tried xdotool and swarp for that. xdotool's mouse reset works not like a reset, but more of a traceback, which resulted in : lets say, rotating left with user input, rotates back to right due to xdotools

swarp did something similar, except it also does a left mouse click whereever it warps, in this case middle of the screen, which resulted in us having difficult time to even close the script

im not primarily into coding so i might need some time to figure out how xautomation works but will definitely try that

[snow harbor]

apparently xautomation also does a "move" action rather than "set". it mimics mouse movements to a position you enter. any solution that does a "move" action/mimic won't work. it should just snap and sets the mouse at x,y

[sturdy scaffold]

So, if I wanted to record infrasound, what would be the best method? Take a woofer and convert it into a microphone, create a microphone from phone barometer, or create a resonance microphone using steel wire and electric guitar pickups? Which one would be the best value (quality/cost)?

If anyone is familiar with Google Sheets, I'm having a brain-fart in regards to Lookups.

My current formula is: =IF(DB_VehicleRecipe!$U$28=0,0,DB_VehicleRecipe!$U$28)

My goal is to make the row number (ie 28 in this example) a variable.

Essentially, =IF(DB_VehicleRecipe!$U$var1=0,0,DB_VehicleRecipe!$U$var1) where var1's value is in another cell. I'm lost in how to achieve this.

Is there any way to know the type of a template variable at runtime?

In c++

I'm trying to write this piece of code which uses templates and I've hit a dead end of some sorts. I've gotta do something if its of type 'a' and something else of its of type 'b'
I tried using typeid and demangling the result but didn't work out for me as the code doesn't compile. I get an undefined reference to demangle ABI::cxx

[deep scarab]

maybe template specialisation?

[visual plank]

But in my case it'd make my code redundant

Like there's this function which remains the same until this very line where the data type is to be considered

I can just write it in a different function but I just wanted to learn a bit bout demangling

@worthy gulch there is a lot of inbetween there too, but what are you really asking about?

both lightweight/minimalistic development enviornments and full heavy weight IDEs have their advantages

and everything inbetween does too

[worthy gulch]

@proper gale I just started developing C++ in Linux

found the terminal and scripts to build, and embedded code app to be pretty comfortable

and less distracting than Visual Studio in Windows for example

but I don’t know what are the limitations of such method, I’m not very advanced

[proper gale]

the main benefit of IDEs, is project awareness

the main disadvantage of IDEs, is project awareness

its the IDE i use for C++, and it uses cmake.

[worthy gulch]

oh, is it free?

[proper gale]

nope

if you are a student you can get it for free though

[worthy gulch]

might want to look at it, I haven’t been having much luck with recommended IDEs

[proper gale]

you ever used IntelliJ IDEA?

[worthy gulch]

oh alright, will check it out

nope

[proper gale]

anything from Jetbrains?

[worthy gulch]

tried netbeans and eclipse

i think i tried something but i dont remember

[proper gale]

Android Studio?

[worthy gulch]

nope

[proper gale]

hmm, well, its JB's C/C++ IDE, sooo

[worthy gulch]

sublime text is not a proper IDE is it

its usually recommended as it but it’s more of a plain text editor with useful developing tools

[proper gale]

yea, no, thats one of the inbetween ones.

[worthy gulch]

i see

[worthy dirge]

why not visual studio

[proper gale]

because Linux?

[worthy gulch]

will check everything you suggested

VS Code aint a ide sadly

[worthy dirge]

you can do ssh remote connection in visual studio

[proper gale]

fuck that shit

development over ssh isn't nearly as nice as on the computer you are on

[worthy gulch]

meh would rather mess with the terminal

[proper gale]

i say this as i have remote dev setup to two servers right now

[worthy gulch]

lol

[proper gale]

i also find Clion to be a beter C++ IDE than VS, but thats mostly preference.

[worthy dirge]

For me , have gui -> Clion, if not -> visual studio ssh

[worthy gulch]

I’m a student but outside software developing field

so even if I qualify it wouldnt be profitable for me, im just an enthusiast

thats why id test out an open source alternative

[proper gale]

they dont really care, doesnt cost them anything to give it to you, and if you like it they do get money later

[worthy gulch]

oh its like autodesk

[proper gale]

@worthy dirge i also deal with ROCm a lot myself, which requires Linux, so i have a few reasons to not develop from Windows

[worthy dirge]

ok

[worthy gulch]

@proper gale imma check Clion then, thank you!

[proper gale]

i really need to move my project to a different SSD, but ehh, and what one to use.

i got both of my NVME drives, but do i want to use one for projects, or not, or should i clean off my old windows one, decisions decisions

[worthy dirge]

JetBrain IDEs are slow as ever. I really want to avoid them if possible

[proper gale]

oh, i just built my computer do handle it

and will be getting a new CPU as soon as TR3000 comes out

hmm, maybe i should give it more than 32GB, its complaining about being low on memory

[shut grove]

Jetbrains IDEs are awesome

[peak mica]

Yes they are.

[brazen sluice]

Ok, so im afraid to ask this question in an actual Programming discord, so ill just ask it here. What is the best way to scrape this table from this site? (im trying to have an automatically updating work schedule offline, incase my work tries to do some funny business)

[vast echo]

do they have an api?

[brazen sluice]

I doubt it, its just a part-time job since im still in school

how do i know if they have an api?

[limpid reef]

You ask if they have an API, or you find out what vendor they're using and research if they have an API. Chances are even if they have one, you won't have privileged rights to create an API key, so your best bet might be scraping the site using python, then outputting it into XML, CSV, or whatever format you want.

Or you could do what I did where I work: constantly hound the company to support a scheduling system that provides an iCal link so it can integrate directly into Google Calendar, Outlook, or Apple Calendar by way of leaving passive comments on every page of internal documentation for the scheduling system.

[cloud knot]

@brazen sluice well, i would look at the source code of the table. most likely it is just a HTML table etc. but without seeing the source code we can't really help you

also in case someone needs python books https://www.humblebundle.com/level-up-your-python

[brazen sluice]

Thanks, I’m afraid the passive comments thing won’t work but I’ll have a look at the API again @limpid reef

[tired bane]

I don't really know python, why does eval('%s > 1' % 0.5) return false

like mathematically what does it mean

[tepid ice]

@tired bane %s is just a placeholder and it inserts in your example 0.5.

so it says 0.5 > 1 which is false ofc

if you write '%s is a %s' % 'this', 'placeholder'

it would output this is a placeholder

[wraith fossil]

Can someone help me understand how to read hex of a drive in a hex editor in MBR

[deep scarab]

https://en.wikipedia.org/wiki/Master_boot_record#Disk_partitioning

gl

[wraith fossil]

Lol. Thank you. I am in a computer forensics class and I’m trying to understand it.

[wraith fossil]

does anyone perhaps how to read the size of the partition in the hex editor?

nvm figured it out

[worthy dirge]

why is priority_queue so much faster than std::make_heap with vector

seems exponentially faster

[tired bane]

is there a way to generate random SHA256 hashes and save them to a file on a GPU instead of a CPU?

not cracking, just generating new ones from random stuff

[next flax]

random sha hashes are just random numbers, no?

like there is no point in doing sha256(rand256()), just use the rand

[tired bane]

thats cpu tho

[next flax]

right, but im just saying you're just looking for a rng

[tired bane]

and not all hex is sha256

[next flax]

sha is irrelevant

im pretty sure it is

otherwise sha is not a very good algorithm

[tired bane]

yes but it would be way faster to just generate sha256 vs generate hex and then check to see if it is a valid sha256 hash

[next flax]

you're missing the point

every 256 bit pattern is a valid sha hash

there is no validity check

something will hash to that

that is a property of SHA being a good algorithm, it uses the entire available key space

[tired bane]

ik, but I want it to just hash out to something alphanumeric

[next flax]

gpu is probably not worth the trouble if you just need an RNG, the bandwidth going back and forth is probably gonna be more than just using a fast rng on the cpu

especially if you just need "pretty good", not necessarily "100% cryptographically secure RNG"

[tired bane]

what is the fastest way to hash strings from a wordlist

[next flax]

if you just need random hashes why start with words?

just generate random numbers

and then convert them to hex

C:\Users\Shane>perl -e "printf( qq~%X\n~, rand()*(2**32) ) for 1..10
9A6F726E
9F3960AB
7E1E6F7
65C5995C
4A9E6053
12C159AF
A32105D5
A9466B37
E8B3DD47
E37715D2

you'll probably need hex values a little longer, but same idea

[tired bane]

I shouldn't have said random sha256 hashes, more like sha256 hashes that are alphanumeric

[deep scarab]

aren't all sha256 hashes alphanumeric?

🤔

[next flax]

if you convert them to hex

[tired bane]

like the encoded string is alphanumeric

[next flax]

SHA is just integers, the alphanumeric appearance is just a side effect of converting to hex

[cursive prawn]

I would recommend installing it

Web compilers can be stripped down and old

[worthy gulch]

quick C++ question: why some APIs refer to its objects (for example, GtkWidget) as pointers?

when initializing, you have to do something like GtkWidget *my_button; instead of GtkWidget my_button; like standard objects such as ints and strings, anybody knows why?

[proper gale]

@worthy gulch because if they used stack objects the API wouldn't be able to comunicate correctly.

unless it uses a heap pointer internally.

in which case, its just hiding it from you, probably with a smart pointer.

C APIs that use ints such as OpenGL are doing basically the same thing, just in a slightly different way, and you must deallocate the object yourself.

[worthy gulch]

@proper gale thank you very much sensei!

[proper gale]

miss me with that weeb shit

[cursive prawn]

You already do c++ there’s no missing that weeb shit

[naive terrace]

does anyone here use certbot / letsencrypt?

I have a few subdomains / certs on boxes behind firewalls, and it's a pain to open them up to renew every few months, and I can't automate w/ cron easily. Is there a better way to do this? I've heard letsencrypt now supports wildcards, but I don't know how to migrate a bunch of machines to all use the same wildcard cert, and if I do, can I renew the certs from a dedicated box open to the internet?

[raven kernel]

I use certbot on my production server and it works great. I'm not sure how you would go about having multiple machines as you would somehow need to distribute the certificate from the dedicated renewal box. It would definately be possible though.

[vernal marsh]

@proper gale my first ever AVX code... seems easy till now

offcourse I don't know anything till now 😅

[deep scarab]

iostream and using namespace std

uses printf anyway

¯_(ツ)_/¯

😄

@vernal marsh congratulations

[vernal marsh]

@deep scarab well there isn't even a return statement 😄 I just overwrote a code so iostream was still hanging up there when I took the screenshot

@visual storm thanks

[proper gale]

@vernal marsh avx isn't hard, its just cryptic and different from normal code.

you also get to use intrinsics that map to a single instruction, which is wonderful.

[vernal marsh]

yeah I get that now.. its actually very simple atm.. I haven't jumped to assembly and stuff but that seems bit over too much right now

[light gorge]

Hello I have a pretty dumb question but I'm learning java and we have to do these programming projects and I'm stuck on this one part

String moneygained = startingbal*interest; this is my code, I'm trying to multiply two numbers that are in those two strings but im getting this error

hmm it wont let me post it, I guess ill send a screenshot

I'm not sure what this means or what I'm doing wrong, any help is appreciated

[deep scarab]

you can't multiply strings

you need to convert them to ints/doubles

https://docs.oracle.com/javase/7/docs/api/java/lang/Double.html#valueOf(java.lang.String)

[light gorge]

Gotcha, once I did that it just worked. Thank you!

[naive terrace]

@raven kernel the issue is that the certs are on boxes that are behind FW's w/o outside internet access

so LetsEncrypt can't verify the page

I figured if they all had the same cert

if I renew one on an external box

all the internal ones also should be updated?

or does it actually update the cert value itself when renewing?

[raven kernel]

yes it does up date the cert value

I think...

[naive terrace]

makes sense

[raven kernel]

actually... 🤔

never checked soz

I would think so though

but yeah proving to letsencrypt that you own the domains will be the hardest part

you could use the DNS method of proving

then letsencrypt wouldn't have to try and find the server

[naive terrace]

for now I just take the service offline, throw up default nginx server, renew, then fix FW rules and bring service back online

I'd still have to update the cert w/ dns method

[raven kernel]

it's hacky but that's what I also do

[naive terrace]

Ideally I want this fully automated

I guess I could do this fully automated too but uhhh

[raven kernel]

certbot has the option to run commands before and after it renews the certs

[naive terrace]

automating FW changes w/ opening to world is dangerous

and having the same box able to adjust the fw is not a great idea either

[raven kernel]

no not really unless your using a reverse proxy

[naive terrace]

uhhh? 😛

meaning yes

nginx -> another service w/o tls

nginx being the proxy to provide tls

[raven kernel]

hang on what's your set up?

you have multiple servers connecting to a reverse proxy?

[naive terrace]

nah, if so I'd use a load balancer or something, since it's on aws. This is a java spring application, where the dev didn't do any sort of TLS implementation

[raven kernel]

so you want to put a reverse proxy in front of it to enable TLS?

[naive terrace]

that's what I use nginx for, yes

[raven kernel]

ohh ok

[naive terrace]

maybe reverse proxy is the incorrect term

[raven kernel]

no it's right

[naive terrace]

but nginx sits in front and adds tls essentially

ah okay

[raven kernel]

yeah certbot can do that

[naive terrace]

can certbot validate on a specific port?

then I can have nginx provide a specific certbot listener port

[raven kernel]

I believe it'll only work over 80/443

[naive terrace]

since it redirects all 80 traffic to the 443 proxy.... hmm

not sure I want to open it up that much still

[raven kernel]

you could have something like

server {
    listen 80;
    server_name sub.domain.com www.sub.domain.com;
    […]
    location /.well-known {
            alias /var/www/sub.domain.com/.well-known;
    }

    location / {
        # proxy commands go here
        […]
    }
}

Source: https://serverfault.com/questions/768509/lets-encrypt-with-an-nginx-reverse-proxy

[naive terrace]

yeah, was thinking that

but still requires making the box visible to the internet

right now, nothing sees the outside internet

[raven kernel]

yeah it's hard to prove something exists when it can't be seen 😝

[naive terrace]

btw does ltt have a channel where we can lurk for people to hire?

[raven kernel]

idk, I'm not the best person to ask.

[naive terrace]

ok. We need a Microsoft guy for azure etc.. xD (or girl)

but yeah, thanks for the help. Not sure there's many options for my use case

I'll look into the DNS verification

[raven kernel]

np, happy to help.

[naive terrace]

and/or an open box w/ a tunnel or something to the other boxes

[raven kernel]

if you have any other questions feel free to dm or @ me

I'll try to help 😄

[naive terrace]

@raven kernel I need help breaking the root certificate for microsoft kthx

[raven kernel]

😝

yeah easy, who's microsoft's ca? 😆

[naive terrace]

uhhh MS actually I think xD

[raven kernel]

wow your right.

they provide there own certs

[naive terrace]

google issues their own too

apple surprisingly doesn't actually

I figured if they ship their own browsers (safari) they could afford to pay google to ship a cert w/ chrome and be their own CA lol

[raven kernel]

I wonder why they go to the effort to create their own CA?

[naive terrace]

I think it goes back to the IE days

IE was the biggest baddest browser

90% of market

so they made their own CA

shipped it with IE

so everyone had it and was trusted

so any new browsers basically HAD to follow suite

[raven kernel]

fair enough I guess.

[naive terrace]

and has been a thing ever since

don't quote me on that, but that's my guess

[raven kernel]

it seems reasonable

when you have that much market share you can do what you want

[naive terrace]

yep

being big is one thing, but being first is another

hence why I think apple doesn't have their own public CA

[sacred shuttle]

https://hastebin.com/wozujeqiha.js Does anyone know why it doesn't come to line 47? Everything till that point works fine. Ping me if you can answer

async_native is the package async. Ignore some of the inconsistencies, I'm still working on it.

[naive terrace]

you can go overkill on console.logs and track what's happening

do one for each line

see where it stops

possibly an exception is thrown? (I do java dev, javascript probably has the same or similar?)

[sacred shuttle]

Yeah, the thing is, there are no errors

It just generates a timeout

And I know where it stops. It's line 47 as I already said

[naive terrace]

Hmm an issue w/ the DB?

maybe missing write perms? except I think that would produce an error, not a timeout

[sacred shuttle]

Yeah

And using google(an alternative register method) it writes to it fine

Sup guys

So I'm an IT helpdesk level 2 and I sit all day in my office doing nothing

And I really want to learn something new in the world of development, from absolute scrach

What would you recommand

I've seen Golang and Rust are new , but are they worth it ?

[raven kernel]

+1 for Rust. I'm still learning it and have been loving how simple (compared to other compiled languages that is) and efficient it is. Although I have also only heard good things about Go so either would be a good choice. I think it would more come down to what you want to do. Go is mostly used for web based applications where as Rust is attempting to be more like a C replacement.

[grand sigil]

@raven kernel thanks! what would you recommand for website creation?what's new in this department ? I keep hearing lots of hate towards php

[raven kernel]

yeah from what I have seen php is dying due to security vulnerabilities. It seems like it's being replaced by web frameworks such as flask, django, etc. which makes sense as it allows the backend code to be easily programmed in almost any language.

[gilded moon]

+1 for learning a framework for websites, whether it's Flask, Django, or even something like Ruby on Rails

[final sun]

How do i hide a driver object?

[proper gale]

@final sun gonna need more context

[final sun]

I have a program that uses a driver

but i need to hide its signature or whatever its called

so that other programs don't detect it

@proper gale

if thats even possible

[proper gale]

i have absolutely no idea.

[potent oxide]

Just curious, what language are you using?

@final sun

[worthy gulch]

been through the pain of working and making my own libraries in C++, done several GTK programs with Lua integration already and even worked with this terrible win32 native GUI stuff, gotta ask

how easy will it be to code for android and iOS?

got no experience in those two platforms

[rough bridge]

How is LUA different in like say a object based Language like java, I have attempted to learn lua but java has a ton of documentation and LUA doesnt have as much

[proper gale]

@potent oxide C, you dont use anything else.

[worthy gulch]

@rough bridge imma try my best to answer: those two are different, Lua is simply a scripting language and its pretty easy, because its syntax is similar to that of your everyday english, but that means less efficiency and, because it runs on C++, itd be tricky to convert to each platform. If you mean Javascript, well yes, Javascript is widely supported and well documented already, thus much more capable, there are entire frameworks built around it.

if you meant literally Java well that's a programming language, which is essentially a different concept

[rough bridge]

I see, so scriping is way different from programming

[proper gale]

not really

lua and java are both turing complete languages

they are used different, but you can write games in lua and scripts in java

and cloudflare runs on lua

also, because luajit its not slow either.

[worthy gulch]

but id say there are more layers between Lua and actual assembly, than in java

[rough bridge]

Ok did a quick lookup, basically when you script,it doesnt need compiler

[proper gale]

there are less though

lua -> interpreter/jit -> asm
java -> compiler -> interpreter/jit -> asm

scripting is a run-time environment.

so, translated from source at runtime.

language is irrelivant.

[worthy gulch]

wouldnt you still be interpreting Lua at runtime through C++?

interpreter itself is written in C, and generally speaking basic arithmethic is performed at a lower CPU task on lower-level languages such as C rather than in Lua

[proper gale]

C is high level assembly, so thats not a fair comparison.

[worthy gulch]

but my knowledge regarding this matter is too limited to get a valid perspective about it

[proper gale]

and with luajit, its basically the same as java.

C++ that takes source and compiles it then runs it immediately.

[worthy gulch]

well java itself is a middle ground

[proper gale]

if there is a lua llvm front end, you could compile it.

[worthy gulch]

i see

[proper gale]

oh, hey, there is http://lua-users.org/wiki/LlvmLua

so I'm trying to set up MongoDB and I keep failing

[proper gale]

@forest sphinx what part of mongo?

[forest sphinx]

Hooking it up to integromat and Heroku

[proper gale]

so, what are you trying to do, and what isn't working?

[forest sphinx]

just hooking it up

I have to hook it up to my Discord bot for Data and stuff but no matter what I try it doesn't work

[proper gale]

there are thousands of ways to "hook it up" to a discord bot

[forest sphinx]

I'm talking Heroku

[proper gale]

so, you have a discord bot on heroku, and it needs to connect to a mongo server?

[forest sphinx]

yes

[proper gale]

so, what part of that isn't working?

because heroku seems to basically just be hosting.

[forest sphinx]

it is

It just won't link

[proper gale]

where is the mongo server hosted?

[forest sphinx]

West Coast

same as me

[proper gale]

via?

how is it hosted

[forest sphinx]

Azure

[proper gale]

how is on it on azure?

because by default mongo only accepts connections from local applications.

[forest sphinx]

thats the Cluster

Hosting it is another issue

[proper gale]

i need to know exactly how this whole thing is setup, and exactly what error you are getting, otherwise i cant really help

[forest sphinx]

You want to see how fucked up it's set up

[proper gale]

i mean, if i dont know then there are thousands of issues you could be having, of varying posibilities.

[forest sphinx]

I can add you to the group

[proper gale]

id rather you dont

[forest sphinx]

TeamViewer/Anydesk?

so you can see the issue

@proper gale

[proper gale]

words, use them.

[forest sphinx]

Thats the issue

I can't see the issue

[narrow furnace]

Check if you have open ports - so the mongo is accessible by outside world

on AWS - default is that your machines are not accessible

[forest sphinx]

It would help if I knew HOW to even do that

but so far nothing I do works

[narrow furnace]

ok - download some kind of MongoDB GUI app

Robo3T e.g.

and in azure - under details you should see IP of your machine

default port for mongo is 27017 if i remember it correctly

[forest sphinx]

port foward

right

@narrow furnace

[narrow furnace]

@forest sphinx yep ?

[forest sphinx]

ok just checking

error: ```Connection failed.

i gtg for a bit

[proper gale]

remember when i mentioned that mongo only accepts connections from local, thats probably what thats gonna be.

[forest sphinx]

how do i allow from any

[proper gale]

there is documentation on that.

[forest sphinx]

o

[narrow furnace]

this can be either bad port (better case) or blocked outside connections

[proper gale]

and i point you to that, bceause i dont know.

[narrow furnace]

you have dev subscription on azure ?

there is some support hours included - i would contact their support (Azure) to help you with this case. They usually response within minutes

[forest sphinx]

no

wait

I have to use Linux
