Is your GPU Cuda compatible?
I don’t really mess around with GPU development so IDK if it can accomplish what you want it to do
stiff gull
@dreamy finch high res timers
take time at start and at end, subtract em and you'll have the duration
plucky vector
looking for some Oracle SQL help if anyone has any knowledge
dreamy finch
@nocturne galleon Yeah it's cuda compatible, It's a GTX 660. Old, but at least had cuda for me to do this final project.
@stiff gull Thanks! I looked into it some more and figured out how to get the time for how long it took to run only the calculation of the matrix. The point is to show the time difference of execution on the GPU and CPU. Like that's what my lab report is on; The benefits of CUDA.
stiff gull
don't forget you have to run it multiple times
not do a single check
since that might influence timings due to start up costs and OS business etc
dreamy finch
20 times each using the same matrices you think?
stiff gull
not even 20
dreamy finch
Then average them?
dreamy finch
Calculate the same matrix a million times?
stiff gull
yeah
dreamy finch
Gotcha.
dreamy finch
I'll have to make it output how long it took for each calculation to a file so I can import those times into excel and get the average of them.
stiff gull
but what you want to prevent is tests being skewed by for example its location in memory (maybe a slower bit of RAM) or the OS process getting a bit less time or more interrupts and all the micro-stuff
thats why you run a whole bunch of them
you could do that inside the program
dreamy finch
Yeah, but I thought I'd make a graph too. My professor loves diagrams.
stiff gull
so for example if I were to bench my distance function:
auto timestart = time();
float dist = FLOAT_MAX;
int shortestPairIndex = numPairs;
for(int i = 0 ; i < numPairs; i++)
{
float distance = Distance(pairs[i]);
if(distance < dist)
{
dist = distance;
shortestPairIndex = i;
}
}
auto timeend = time();
this would be wrong
it only runs once
auto timestart = time();
for(int n = 0; n < 1000000; n++)
{
float dist = FLOAT_MAX;
int shortestPairIndex = numPairs;
for(int i = 0 ; i < numPairs; i++)
{
float distance = Distance(pairs[i]);
if(distance < dist)
{
dist = distance;
shortestPairIndex = i;
}
}
}
auto timeend = time();
this would be better
then you div the end result by a million (operations) and you get the time per op
dreamy finch
I haven't tested this running on my GPU yet.
Only CPU for now to get the code working
Also, I have to go get lunch with my dad and brother, so I'll be back in a bit.
But thanks for the advice!
dreamy finch
That's what I thought. Nice!
dreamy finch
Yep. Exactly what I thought I was going to have to do.
I'll see you in a bit. I have to go for a bit.
Thanks, though!

@dreamy finch perhaps a good idea to use pastebin and to put your thoughts in a single-message. Bot tends to smite people that send too many messages of short length in a short period of time.

How can I run an SH script on the Python interpreter after SSH login? What it does is after SSH login, it checks who the private key belongs to on the SQL database and then checks if the account associated with it is currently suspended or is denied access to SSH, and if so it kills the connection process
dreamy finch
Oh, jeez. It got rid of my code I posted here, huh...

subprocess.call(["sh", <instert path to script as string here>])``` @jade nova@stiff gull Do you know anything about getting code to run on CUDA? If so, would you mind helping me figure out where these pragmas go so that OpenACC works properly? You seem to know more than me on this.
stiff gull
pff I've done one CUDA project really and know nothing about OpenACC
all I know is you gotta init CUDA, write a cuda kernel (CUDA code), compile it and run it
I used a cuda template which was made for CUDA 8 which is outdated now
anyhow im off to sleep now so can't really help much more
dreamy finch
Gotcha. No Worries I just messaged my professor about it.
proper gale
@dreamy finch i know how to use OpenCL.
also, to get a proper benchmark, using the same data multiple times is not a good idea.
GPUs use prefetch even more heavily than CPUs do, and that could give the GPU even more of an advantage over the CPU.

@nova moth It's pretty straight forward.
Use IDA to decompile the process, look for strings and names hinting at locations of functions using the offsets, you will likely see the pointers + offsets used right there.
Failing that look at that location in a debugger (CheatEngine is easy to learn), set a breakpoint, let it break and follow through the ASM if you want to be thorough.
If the process is written in some higher level language though there is almost always better ways to tackle a problem such as reflection for C# etc. and just modify the ILASM. <- almost any unity game for example. Great for modding.
winged obsidian
@solid horizon Without looking into it too much it looks like you are creating STA UI within an MTA model. This is probably your issue, also the MTA attribute doesn't have an affect on any other method than Main according to the MSDN documentation.
Someone else may have more insight for you. Hope that helps.
You will need to set it explicitly with the [STAThread] attribute as C# uses the MTA model by default I believe. (Unlike VB.NET)
Might be some race condition or blocking that I can't see but I would put my money on this being the issue.

struct collegeStudent newFreshman;
int financialAid = 24000;
for(money = financialAid, money > -36000, money--)
{
newFreshman.assignments++; //Get a shit ton of homework
newFreshman.happiness = -.01 * newFreshman.assignments; //Get sad with more assignments
newFreshman.avgHrsOfSleep = newFreshman.avgHrsOfSleep * (newFreshman.assignments/10000); //Loose sleep as you reach your assignment threshold
newFreshman.sanity = avgHrsOfSleep/8 //Loose touch with reality the less sleep you get
newFreshman.gpa = (sanity/100) * 4 //Your GPA is only as good as the health of your brain
}
do
{
newFreshman.debt++;
if(collegeStudent.gpa <= -7)
{
break; //just drop out
}
} while(newFreshman.degree == false); //wasn't newFreshman.degree a const tho...
newFreshman.alive = false;
}

looks more like c than c++ tbh
winged obsidian
this is why I recommend using if(someBool) and if(!someBool)
instead of if(someBool == true) and if(someBool == false)
to avoid those typos like accidentally using the assignment operator, and it is more concise.

holy fuck I forgot the ==
lmao there's like no reason why I'd do that...

I have several questions regarding webdeveloping in html/css and jquery. anyone here to help?
well here is my question: i got a pretty basic html site. now i wanna load content dynamically into the div, for example that the user clicks on the navbar links. i tought about something like this: https://www.jqueryscript.net/other/Dynamically-Load-Content-Into-A-Container-with-jQuery.html
vestal glen
so far no question?
(very confused as to how that relates)
depends on the dynamic content, my friend^^
gentle summit
well, my question is like: is there any other elegant way or is this pretty good?
vestal glen
also, you rarely need jquery.
gentle summit
dynamic content is basically plain text/html.. nothing fancy
vestal glen
@gentle summit it's fine, but use a recent version of jquery at the very least.
(I'd presonally not load that stuff in dynamically and instead just show/hide it if I wanted to keep it on one page, but w/e)
no.
you can use jquery with static html files served by apache/nginx/whatever juuuust fiine.
and vanilla JS too^^
I don't think about how your site works, sorry.
(I've also tried to not assume gender, just btw)
my point remeains, no need for a backend for what they're asking to do.
will they end up needing a backend for other reasons? Possibly, but not what they asked about.
dynamic content = client side modifications.
at least from how they described it.
who said there has to be an API backend if they want to load some HTML in? (also, nice tie fighter ascii art 😉 )
(and yes, they specified they wanted to load in html)
@gentle summit to loop back to your question, you can also do this in a couple of vanilla JS lines assuming you have an iframe in your page. And as I alluded to, there's nicer ways to do such things these days (SPAs, history API etc). ```js
document.addEventListener('click', function(e) {
if(e.target.matches('a')) {
document.querySelector('iframe').href = e.target.href;
}
}, true);
@gentle summit hm, actually I wonder if target navigation works with iframes like in the good old frameset days, but I don't care enough to look into that.
gentle summit
hmm im looking into that.
just for clarification, this is my current site in buildup. (no fancy stuff, just information) https://thurrax.evonix.eu/
(just fyi: navbar will be added in next update)
vestal glen
@gentle summit you may want to avoid this dynamic navigation stuff if you want to be able to link to individual subpages unless you want to write code for that.
(history API or using URL hashes)
(or use a potentially js free approach with hashes and toggling visibility 😉 )
gentle summit
i once had some similar way but not that dynamic 😄 i just wanted one index file and "semi-dynamic" content.
<?php
if(empty($_REQUEST["s"])){$s = "home";}
else{$s = $_REQUEST["s"];}
if(file_exists("./sites/".$s.".php"))
{include("./sites/".$s.".php");}
else{include("./sites/home.php");}
?>
and site was like: http://mysite.gov/index.php?s=home
dunno if that is pretty but it worked
vestal glen
nice way to let me read any php file on your server 😉
vestal glen
well, usually the point isn't to be able to include any php file, but I know what you mean 😃
(btw. this is how to do css only "navigation" with toggling visibility https://www.w3.org/Style/Examples/007/target.en.html and if you want a challenge, try to do it without using z-index)
gentle summit
that solution requires whole content in the div right?
vestal glen
yes, that means you load everything in a single html file
gentle summit
hmm. i will try to use that.
nocturne galleon
can someone help me - i need them to test my program and try to essentially break it,
explanation: i made a youtube to .mp4/ .mp3 converter. i would like others to see if they can break the code - as no code is perfect. i prefer not sharing the source code (cause this took days to make it to the stage it is, even though it is a simple library of videolib and ffmpeg but non the less), so anyone?
gentle summit
oof. now i tried abit jquery and locally it works but i uploaded it onto the webserver and now it doesnt work 😄 wut
^forget that.. stupid cloudflare cached my css..
stiff gull
@nocturne galleon if it's not a paid app there's no reason to not share the source
nocturne galleon
Well, guess that changes things then.
stiff gull
Just saying that because all you're doing by hiding the source is making it look like there's something to hide (a virus?)
especially if its just a small project glueing some libs together
solid horizon
^
winged obsidian
In this case yes, there is no reason to hide the source, but that is certainly not always the case for all not-for-profit projects.
Anything that has security measures IMO should not be public otherwise those measures can be bypassed without risk of detection or reversed (more easily) to gain access to information for malicious purposes.
(gaming, anti-malware, security, password managers to name a few off the top of my head).
obsidian bluff
If your security program is well-made having the source code out would only make it more secure.
winged obsidian
Yes I agree, in some cases with the key word being well-made or rather, having a security-focused team leading the development.
timber prawn
To be honest... gluing some libraries together isn't anything special. I could make exactly what you described in ~30 minutes w/ NodeJS.
Sharing the source doesn't hurt, not to mention that it gives the opportunity for improvements.

Need to vent for a moment. Codeveloper is acting senior despite betraying the fact that he doesn’t know what he’s talking about, and has management support. He’s pushing us to use a shit ORM because he sees a little bit of raw SQL and panics—essentially, he wants to use the ORM and for me to not use SQL because he doesn’t know SQL and doesn’t want to learn.

Doesn’t help matters that he just unwrote a month’s worth of code because the return was formatted incorrectly, because he never bothered to tell me he’d established the format to meet another team’s needs, and said nothing despite me showing the change off repeatedly on scrum and demo.

Idk... I've just been conflicted lately. I've always been super elite to myself not allowing myself to have any fun. I always limited myself to C++ no matter what. And up until recently I even tried to only use native windows API calls.
So I rarely code
I will go without coding for months and then do a small project
And I just feel like even though I've been trying to learn for years and years I just haven't gotten very far
I always had an aversion for libraries for some reason.
And higher level languages for that matter

I agree, use what is sensible, avoiding libs really isn't practical but don't feel like you need to use a lib for everything (cough JS cough)
I agree to some extent, but I prefer using typescript

With preprocessor directives to adapt it

This may give you an idea of how fucked it is
Those are all GDI functions

So @last ingot I got the code somewhat working haha
only issue is now that it doesn't get the positions correct xD
oak parrot
anyone have any ideas
import math
value = math.pi
Pi = str(value)
number = input("Enter your number: ")
Pi2 = Pi.split(str(number))[0]
Pi3 = Pi.split(Pi2)[1]
PiL = len(Pi2)
NL = len(number)
PiP = PiL - NL
print("Pi position:",str(PiP))
@oak parrot if(string == "42") return 92;
It said it at bare minimum needed to work for that value
Meets requirements

@last ingot https://js.tensorflow.org/api/latest/
didnt say it was common, but it exists.
there is Python, JS, C++, Java, Go, Swift, (3rd party now) C#, Haskell, Julia, Ruby, Rust, and Scala
im aware of that, never contensted that python is the dominant language.
simply that other language bindings, exist

nocturne galleon
kind of a silly question, but do professional programmers just learn the syntax and control structures of the language they are using plus any libraries they need for the program they are making? or is there something else they need to learn as well?
proper gale
@nocturne galleon i mean, the syntax, control structures, and libraries for a language basically is that language, so to literally answer the question, mostly yes.
the hard part to learn is the problem solving
nocturne galleon
oooh ok
proper gale
a coding language is just a way to express a solution to a problem.
i could write code that solved the same problem in 4 languages
nocturne galleon
so if I know how to use a language and I learn the libraries I need for a program im making thats all I need to 'learn' aside from the problem solving?
proper gale
tldr: yes.
nocturne galleon
cool, thanks
proper gale
that is a hell of a lot easier said than done though.
nocturne galleon
thats probably why it almost seemed too simple
because I was thinking "theres no way thats all there is to programming"
proper gale
saying thats all there is to programming is similar to saying that all there is to:
driving is watching the road, turning the wheel, and pressing the pedals
painting is mixing paint and putting it on a canvas
using a computer is pressing the correct buttons
its not wrong, but it doesnt really explain everything.
proper gale
there is a hell of a lot more to it, as there is with everything
nocturne galleon
is the 'more to it' the complexity of said problem solving?
proper gale
the problem solving is a good section of it
but there is also knowing how to use your IDE
nocturne galleon
like the built in tools etc?
proper gale
basically, yes.
making code both maintainable and fast.
choosing the correct language and library for the job.
etc
nocturne galleon
aaah ok
so you choose the language based on which one is made for that sort of purpose?
proper gale
most are general purpose, soooo, no not really.
it usually comes down to ease of writing and speed
nocturne galleon
ok
nocturne galleon
would c++ be a faster but generally harder to write language?
proper gale
this is rule of thumb, and is not true in all cases.
C++ is a fast but absurdly hard language.
dm me what you said, i could see that you pinged me.
i didn't specify IDE
i guess i specified Integrated, but you do you and use a non integrated environment.
and? how is that bad?
its quite nice to have an IDE do some of the work for you.
nocturne galleon
"dm me what you said, i could see that you pinged me." are you talking to me there?
proper gale
no.
also, the syntax highlighting and project awareness of an IDE, very, very, nice.
i use CLion for C++
i dont even bother to target mac
why cant windows error like Linux?
also, WTH GCC, give me better errors like Clang does.
and CLion would have caught those type errors for you
afaik, yes
what specifically are you looking at?
i am
Clion has regex search
double shift you can search symbols, etc.
yup, double shift is search everywhere
and you can include non-project files.
yes
i use it for both C++ and Python personally
C++, Java, Python, Lua
and somewhere GLSL and OpenCL C
of which, Clion supports all but Java
Lua has an easily integratable interpreter
how is Java bad?
people hate on it, i fail to see its fatal flaws.
its not, particularly.
i dont know.
i can talk about things Java does well compared to C++ and Python, as i have experience with those languages.
tropic sapphire
How about the fact that JavaScript doesn't have any type support? Or that [] == 0 is true?
Or that although the async nature is super good it's harder for people to get their head around.
proper gale
in order:
Generics is a problem
static, nuff said
problem with teaching, not the language
this is annoying, and thats about it
operator overloading is both good and bad
this could be solved at the compiler/vm level
again, compiler/vm level
same as other languages,
haven't use the lib
no other language is any better
i wont say its good, but its not all that bad either
C
C is very close to a subset of C++
C++ was originally called C with classes
tropic sapphire
@last ingot I know that it was to your comment about dart and js beating It
Plus I thought we were just bashing on design flaws. :O
vivid wasp
C++ is an "extension" to C
proper gale
no, Objective-C is
tropic sapphire
I use node at work, inside aws lambdas it's super good.
proper gale
if you want to bash on design flaws, i could go on for quite a while about C++
vivid wasp
Didn't say they are equal. 😄
proper gale
and mostly the libraries
timber dagger
hello
proper gale
i think its fair to include the stl as part of the language.
and the language (no libs) has its flaws aswell
tropic sapphire
@last ingot python docs are great but so is c#. Microsoft has put a tonne of resources into docs over recent years
proper gale
the standard library for a language, they all have them, i think its fair to bundle them.
i wish docs were good for C++
tropic sapphire
We have .net core.
proper gale
they really aren't
you mean the iterator loops?
index loops are still faster, no?
im using the C++2a CLang 8 lib, soooo

proper gale
least of issues
i would have expected to use the continual compound, but i dont see the pert formula anywhere
vestal glen
oh, I know, it's a symptom for a whole class of things to come
nocturne galleon
@proper gale the interest rate is fixed, so it should just calculate the percent of what is left of the loan after each payment. and ya i took out the system.exit(0);
proper gale
figure out the math first, then try and do it in java.

RewriteCond %{REQUEST_FILENAME}.png !-f
RewriteCond image-dir/%{REQUEST_FILENAME}.png -f
RewriteRule (.*) image-dir/$1.png [L]
Basically, if the image (image.png) doesn't exist in https://website.com/'s root, check https://website.com/image-dir/ for it. If it's there, show the image as if it were served from the main site (https://website.com/image.png).
Hastily trying to fix my screenshot links now that Discord introduced a new bug that no one cares to acknowledge, so I'm forced to change a system that's worked flawlessly for years on the account that their shit's borked.
It's an htaccess file.
@last ingot As i'm serving content from a sub-directory, it's the only way to possibly achieve such a thing without a gaping security issue.
I hate dealing with these files because they're buggy af half the time.
At least the main placeholder page works, and the music bot always works 
https://m.dooleylabs.com/
I use Cloudflare for that, but memcached and other configurations with a caching VM would work in your case.
Other thing is, the server handles the request so quickly, I'm not able to see if the rule's remotely doing anything, or if the 404 page is taking everything over and ignoring the htaccess file.
limpid reef
Boom @tropic grail -- hides the SubDir too. Also, Document_Root may not be needed, but it's what I tested it with. Removing it & the / before pics still works.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ %{DOCUMENT_ROOT}/pics/$1 [L,NC]
Tested on a cPanel server running Apache on top of CloudLinux. (and it's not even good hosting either - it's an old HostGator account I still have.... for some stupid reason.)
tropic grail
My reaction that it works 👀 https://giphy.com/gifs/reactionseditor-wtf-mind-blown-l0IypeKl9NJhPFMrK
limpid reef
Ummm... is that a good reaction because it works, or... did I make your server catch fire?
tropic grail
Both.
So in the way you provided it, it works, but only for the images in the sub-dir, which is great, but everything outside the image dir becomes a 500 error, and for some reason, it's recursing into itself to find a non-existant favicon. @limpid reef
@limpid reef I'd like to be able to only catch image files from this directory as long as they're in the first position of the URL, which works in your example, but bricks the rest, lol. So far, yours does more than mine did, but sets other stuff aflame 
limpid reef
😄 hey now, i didn't say my solutions are perfect. 😛 do you have a RewriteBase specified? I forgot about that, just a moment. ... oh wait, i dont have one either, but I can access files inside my test directory just fine so....
tropic grail
png, jpg, jpeg, bmp, gif, webp, webm << those are the only extensions I need, others aren't needed, and favicon.png or ico can be ignored.
limpid reef
just a sec, gonna finish this overwatch game then look
tropic grail
Tested it alone in the file, but still sets the rest on fire.
limpid reef
That's what I'm thinking yeah.
tropic grail
Testing now, but seems to work with some half-assed regex I tossed in.
limpid reef
Yeah, I understand the concept of RegEx but am definitely not an expert. This seems to work in my test case. Leaves my other files alone.
RewriteRule ^(.*\.(jpe?g|gif|png|txt))$ pics/$1 [L,NC]
👀 I'm tired, lol.
So if I try a file that doesn't exist, it goes into a loop instead of redirecting to a 404.
@limpid reef @deep scarab
deep scarab
i've no clue what that language is
tropic grail
What do you mean?
vestal glen
that's apache htaccess with some regexp^^
vestal glen
well, you could avoid the loop by telling it not to redirect in the /pics subfolder
limpid reef
This makes sure the file actually exists, otherwise 404 or whatever your server is configured to do. Give it a go Dooley, then I'ma sleep.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond pics/%{REQUEST_FILENAME} -f
RewriteRule ^(.*\.(jpe?g|gif|png|txt))$ pics/$1 [L,NC]
or that
tropic grail
@limpid reef I swapped your [L] for [END].
limpid reef
lol i totally forgot to re-add that.... oops
tropic grail
END is only for the last line of the file though.
I've popped your tweak in there just in case since it's a smart thing to add, but I'm happy that the old links redirect into the new ones at least, lol. It's all about simplicity.
^ Weirdly, Discord won't let the old links function anymore, but the new ones do. New "features," eh? https://dooleylabs.com/nerd3x.png

Hey guys..
Anybody know a good place where I can start learning solidity?
Yeah.. I'm an electrical engineer with some programming background..
Yeah, but I need a good resource on the Internet for learning it as most of the ones I found couldn't really explain it that well..
Guess I should really get into the habit of seriously reading the docs.. 😉
@last ingot Thanks though..
In my case, I guess, it's not the language itself that bothers me but finding the answer that why should blockchain be used for an app (dapp in this case) when the same thing can be done better via another language..
Excluding the security and other applications of blockchain though..
You can't do much about the stuff uploaded on the blockchain but the website where the dapp is uploaded is vulnerable..
So it's not exactly "decentralised"..
@last ingot What do you mostly code in and for what purpose if you don't mind me asking..
So you do it just for fun and not, like, professionally?
Oh, good luck then..
Well I guess I should better get some sleep.. Its 3.19am here..

do you perhaps know if this thing might influence my C code?

depends do you handle unicode?
normal characters only go from 0 to 128 (or 255 with extended format)

What I'm trying to do is split an input file into strings via strtok and then see if all elements from the input file are valid and make sense

that might be an end of file character
check the man page for whever you're using to read the input file, and see if it leaves an eof character in
if so, you need to account for that
supple abyss
Man page? Whats that
fresh lance
are you on a linux machine?
supple abyss
No
supple abyss
I'm confused, what should I be looking for?
fresh lance
I ask because there's a nifty feature in Linux where you can run the command "man [command]", where [command] is a bash command or C function
and it gives you the manual page for it
this site emulates that
enter the c function you're using into the site search
for example, fscanf
or strtok
and it'll tell you everything you need to know about how that function works, including how it handles things like eof

@winged obsidian I've been using this for a few months and I am a software engineer, but it would definitely be great for gaming. It's a great keyboard.
I've got their linear switches as with the non linear when coding the keys take more of a press to execute it fully.
And it comes with that wrist rest which is really nice.
I also have it paired with this on a large mousepad and it's great.

And I have a quad 4k monitor setup which is very useful

Is there any way in JavaScript where I can calculate how many bytes are in a HTML/CSS/JS file?
bleak parrot
maybe with fetch All 🤔
obsidian bluff
@full berry Bug is in the second for loop which decrements. iterator integer gets converted to a string and then parsed and is used as the sum. Instead of course you should be indexing s1 (the longest string)
So it would be int sum = int.Parse(s1[i].ToString());
Also me personally I'd assume the strings are in ASCII and just subtract 0x30 from the raw characters so you wouldn't have to call ToString or int.parse
Though that's probably bad practice in some way or another
And biginteger is probably more efficient anyway because I assume it stores the numbers in base16
And probably has various other optimisations
full berry
@obsidian bluff swatted the bug congrats
No they are in an encoding scheme only aliens know
And ofc bigint is cheating...
winged obsidian
Yeah pretty much, in that BigInteger does use the char values to make the calculation. Uses the NumberBuffer struct, so not base16, just an array of bytes representing each digit, the precision, scale and sign are stored in that struct also.
BigInteger also handles white spaces, grouping, negative numbers (sign), floating point numbers, currency, hex numbers, parenthesis, exponents, etc. Very robust.
It also has a ton of built in methods as you would imagine.
yeah cheating, but worth mentioning for sure.
obsidian bluff
Lol. Makes sense to me. A class named BigInteger can do floating-point
full berry
Yea... I think he meant bigdecimal
And not sure about javas implementation but I think .net bigint is base256

How can I do like in #472210112686325770 that when you click on an emote it gives you an role? I'm working with discord.js

Mention me if you've answer me, otherwise I won't see it

@sacred shuttle I'm sure there is some kind "on-react" event going on or similar
something you could deduce that from
restive estuary
There is. Let me find.
https://discord.js.org/#/docs/main/stable/class/Client?scrollTo=e-messageReactionAdd @sacred shuttle
sacred shuttle
Will look at that
client.on("messageReactionAdd", (reaction, user) => {
let member = reaction.message.guild.members.get(user.id)
if(!reaction.message.id === "526372510200233984") return;
let role = reaction.message.guild.roles.find("name", "Updates")
if(reaction.emoji === "✅") member.addRole(role);
});
This code doesn't work. Can someone help me?
Mention me if you've got an answer
restive estuary
Any errors?
obsidian bluff
I'm no JS expert but maybe try two equals instead of three?
@sacred shuttle
And Shouldn't you use like !== instead of !something === something else?
because I think
if(!reaction.message.id === "526372510200233984") return;
reads as whatever the result is of !reaction.message.id and see if it's === to that number string.
reaction.emoji is apparently a "ReactionEmoji" object or an "Emoji" object
if you check a string to be equal to an Emoji with === no type conversion will be done so it will always return false
You should do reaction.emoji.toString() === "✅" or reaction.emoji == "✅"
sacred shuttle
Already found it
It didnt work because it cant read old messages after a restart

Guys I had an idea for an app. Are you watching a movie or listening to a music on your laptop with shitty built in speakers or no speakers at all? What if you could use your phone as a speaker? Your smartphone and computer would connect via WiFi ( Bluetooth if available ) and just. Reproduce the sound on your phone. Obstacles to overcome? Latency. What do you think?
full berry
@ionic hull that already exists
and... WHY? I doubt phone speakers are going to be better than the ones builtin
nocturne galleon
hey guys, im new to github, how do I access the releases of someones repo? thanks
vestal glen
you click on "releases"
ionic hull
@full berry I've Ben in this situation many times
Thought that other could be too
And there can be better things
full berry
Well, if you really want to its entirely possible and on local network latency should be negligible
It would basically be a client server environment
Good luck, happy coding
vestal glen
wonders if you couldn't just use DLNA for that, but nobody even remembers DLNA anymore now that we've been forced to use proprietary things like google cast or airwhatever
full berry
One would have to capture audio anyways for the dlna server
vestal glen
pretty sure on the good OSes (linux) it's pretty straight forward and a solved problem. Never tried it on something else.
full berry
And I'd argue dlna is kinda overkill lol
vestal glen
I mean, it kinda is, but it's something that is out there and works modular, so you can just take a random client and it'll work with your server. So it's even more than phones 😮
full berry
I'd just ffmpeg on both ends. One encodes, other decodes

I would have to stream the sound on local network

I'm just saying you wanna make native apps then make native apps. Dont pretend to...
Like discord.... Because they electron sure they have high portability but in terms of quality its shit
The linux version has so many bugs
Windows version doesnt behave as expected either
Ofc the reason is cost and time
Aka cutting corners

Unless electron is fixed

Well you could meet in the middle and learn a relatively lower level language like java, c#, vb, c, cpp
ionic hull
I'm not gonna say that I know c# or Java or c++ but I've used them for a few projects
full berry
Js was made for scripting... I like to keep it that way. If I want lower level capabilities I use a lower level language/environment
ionic hull
I just don't see what I could do with them rn
If web development gets me money, that is what am doing
full berry
Im guessing you dont plan on going that far lol nvm then.
full berry
The app im sure can be done. At least the client side easily enough by you. The serverside is what im wondering
How do you plan on capturing desktop audio etc?
ionic hull
There sure is some c++ lib for that
full berry
So you arent using js? Thank goodness
ionic hull
Ofc not
I would use c++ with what I know ( basically gluing a lot of libraries together )
full berry
And here i was thinking sonehow this websev was gonna do it all via web dev lol
ionic hull
It would be funny if there was a way to do it in mode and Electron
full berry
Im sure there is
ionic hull
And save the audio to an mp3
full berry
But plesse dont
full berry
Id capture. Encode and send the bytes on the line asap

Grrr... Linux hates my ethernet chip on my motherboard. Had issues with Antergos not seeing my ethernet so installed POP OS and the exact same crap. Spent like 8 hours trying to compile/install the driver in like 30 different ways and no matter what I did it would never show up in ifconfig. Gave up and took my wireless card out of my "server" and that worked immediately.

@nocturne galleon if there's no "N releases" stat in the bar above the files browser there are no releases. If there is, click on it...

Except there are releases because I have gotten to them from direct links but there is no button for it
vestal glen
If there are releases/git tags it'll have the "n releases" thing (in the upper middle) like this repo. If that's not there, the releases aren't managed via github.

@obsidian bluff thanks - I've been using the core audio api which includes the mmdevices - unfortunately the device state only gives me the driver name (weird maybe it's different per device),
Non the less if I do find a way to get this working I'll probs share it on the web to make it easier for others

DB question: are there any technologies out there that do a best-of-both-worlds approach regarding SQL and NoSQL? Or is there any reason I shouldn’t write a data layer to my app that does that?
fresh lance
You can't really get a "best of both worlds" between SQL and NoSQL
unless you mean something that's not the main benefit of one of these
analog tapir
Well you can use a hybrid of both
And Postgres scales pretty well up to 40-60TBs
After that it gets a bit trickier

Can Java get all active network connections to a computer like netstat?
All I’m seeing on Google is about network interfaces and determining if internet is available
full berry
I'm sure it can
obsidian bluff
Even if it can't you could write a library for it with JNI
Or if you can't do that for whatever reason you could use runtime.getruntime().exec and parse the output of netstat.
Should be straightfoward enough
And on Linux it'd be just /proc/net/tcp

There isn't a linux discussion (Please add one) But anyone fancy helping me figuring out a solution to something I need done on bash? I'm trying to figure out how to put file names in to a output.txt file if the filename doesn't already exist in the output.txt I know I can use a ls > output.txt but trying to figure out the best method to check if the filename is there and if it is do nothing but if not get it to append the new filename in to the output.txt file, any pointers would be great 😃
glad terrace
do a 'ls' into a temp file then use comm and get the difference and add the difference to output.txt
You don't even need to put it into a temp file actually. I use this to compare branches between my local and remote git "comm -12 <(sort <(git branch)) <(sort <(git branch -r | sed -e "s/origin///"))"
It just tells me which local branches are also on the remote so I know which of mine I need to remove from remote

Does anyone know vbs script and can explain what this code is doing?
Set colSettings = objWMIService.ExecQuery ("SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled = 'True'")
For Each objIP in colSettings
For i=LBound(objIP.IPAddress) to UBound(objIP.IPAddress)
If InStr(objIP.IPAddress(i),":") = 0 Then Echo objIP.IPAddress(i)
I don't know vbs but by looking at it it seems to be to display ip addresses that are using ipv6 based on the ':' part in the InStr function.
actually
The opposite.
IP's not using ipv6
native shoal
@glad terrace the opposite because of the = 0 part?
glad terrace
yes
Based on the assumption that if it contains a : it would return a 1 I didn't look at any docs
native shoal
@glad terrace hmm. Is it also safe to assume that if it locates a : symbol, that it would skip the entire IP address object and read the next one?
glad terrace
Not sure about 'skipping' but it wouldn't echo it I'd think. I have never worked with VBScript and am completely unfamiliar with it's syntax so take everything I say with a grain of salt lol
native shoal
@glad terrace thanks for your input
full berry
it loops through each item in colSettings and iteratates through all of the address, if the ip address doesnt contain ":" then echo the ipaddress

anyone know how to access (read/write) files in C# via volume ID?

InStr gives the position (starting at 1) of the first occurrence of a string within another string. 0 is returned if an occurrence doesnt exist.
