does this look right? I am trying to display the generated picture as .webp here:

okay, so I implemented the changes and it runs the prompt, but the image doesn't show? I see no errors in the Chrome inspector

Only two things I'm getting. The first one is probably a browser plugin

[wooden shore]

That second picture is just a warning, won’t break anything

Here are the docs: https://platform.stability.ai/docs/api-reference#tag/Generate/paths/~1v2beta~1stable-image~1generate~1core/post

why is the javascript not in it's own file?

[fresh valley]

It seems to me like it’s just a school project or just quick introduction, and he confesses that he’s only just started learning so it might take a while to recognise and develop best practices

[nocturne galleon]

Anyone like my code?

"Python"
math = int(input("Math equation: "))
if math == "0 + 1":
print("1")
elif math == "0 + 2":
print("2")
elif math == "0 + 3":
print("3")
elif math == "0 + 4":
print("4")
elif math == "0 + 5":
print("5")
elif math == "0 + 6":
print("6")
elif math == "0 + 7":
print("7")
else:
print("idk")

🙂

[modest tartan]

im pretty sure you can make that more simple

you could also just do it in a loop

[nimble sand]

I literally just started learning it a week ago, I have a full time job so I've been reading an hour or so a day

My local barber asked if something like this can be done so I thought I'd try it in JS

Originally used RShiny but it doesn't handle animations very well

[modest tartan]

i barley know how to program myself im just pointing out a more efficient way of doing it with less code

[nimble sand]

Thanks for the info

[spring cradle]

it's a joke cause they're brute forcing addition lol

[inner wraith]

Not really, every single line is fundamentally broken, if the syntax, typing and logic were not flawed it'd be useless.

I could explain why every line is wrong but I doubt there's any point because it's either a bad joke or you've never actually tried to execute a Python program you've written.

[molten oracle]

I'ma just say eval exists...

[nocturne galleon]

ik its just a joke

im learning python at school sooo

[frozen flame]

And it should absolutely not be used

[cosmic moth]

hey i don't know if this is the right place to ask, I'm learning the cryptography library in python, and i ran into an issue using padding:
my server receives a padded message from my client, but when i use the unpadder, it returns an empty string.

i have initialized the unpadder like this:
unpadder = padding.PKCS7(HEADER).unpadder()

and call it like this:
msg_length = unpadder.update(msg_length).decode(FORMAT)

[hybrid dew]

Hello guys !
I want to know if anyone here has already or would know how to bios mod a motherboard, because I have some high-quality HP proprietary motherboards, single-socket, and the problem is that if certain proprietary cables are not connected (USB port and other stuff), it asks you to press enter, which is complicated if you're remote. So, I need to bios mod the boards/or try to find a workaround and P.S. I'm too lazy to buy the cables in question, they cost a fortune, thanks.

Here, if anyone is up for it or has had a similar problem, I'd appreciate it.

[sudden cosmos]

it looks like you're supposed to call update() with the data, not with a length

[cosmic moth]

the naming scheme might be a bit off, but msg_length is the padded data

[sudden cosmos]

idk haven't used this before but the documentation is showing it called like

msg = unpadder.update(msg)
msg = msg + unpadder.finalize()

to get the full unpadded data out
https://cryptography.io/en/latest/hazmat/primitives/padding/#cryptography.hazmat.primitives.padding.PKCS7

[cosmic moth]

Thanks, i tried but when i add the finalize() it raises this error: cryptography.exceptions.AlreadyFinalized: Context was already finalized.

[noble plover]

i could do with this information too, i need to update the bios on my hp socket t system to support dual core cpus

[keen sorrel]

Is the firmware flash on a socketed chip? Depending on the era of the device, there are a variety of complications that may exist to stop you from modifying or analyzing firmware. Modern devices can employ a physically uncloneable function that raises the bar to a fairly extreme level.

is there a easy way for a raspberry pi running openPLC to force a another linux pc to launch a music file, and then force close the file later? They are just 2-3 meters away from eachother

[peak acorn]

Are you restricted in any way on how that communication is dealt with? I Think it makes more sense just to make a lightweight server software on the pc which plays audio via an api

[silent gust]

Python fastapi library is pretty straightforward

[frozen flame]

ugh fastapi

good starter lib but really sucks for anything beyond starting on a project

[peak acorn]

Never heard of it. But it sounds like the guy I was responding to just needs a super simple way to get messages between machines

I mean for just a simple basic api, it does the job, flask is a nice one tho

personally i dont like flask

Hey, does anyone know how to edit dlls ?

I'm trying to mod gta4 but I have two different dinput8.dll. One is for a general fix of the game (FusionFix) and the other one is to increase the vram available to gta4 (rockstar messed something up and if you have an amd card you may be limited to 512mb of vram)

[wooden shore]

Diff them in a hex editor then just combine the changes into one dll

[pastel oasis]

what programing langureses are the best for each catergory

[old flame]

depends what you mean by category cause realistically you can program anything using any language if you have the will and courage

[molten oracle]

Even "best" is pretty subjective

they all do what u tell them to do

unless its machine learning related then they do what u teach them to do

Hey Guys My Name Is Matt Im 17 Years Old Learning To Code Ive Tried A Couple Times Before But Failed Due To Having No TIme Currently Im Learning The Basics Of HTML And CSS Then Im Going To Work More With Javascript Then Hopefully Using Javascript As A Base For My Learning If Anyone Wants To Give Me Any Tips Feel Free To Inbox Me

[frozen flame]

tip: for the love of God dont type like that

[red mulch]

C is the best language at being C, for example.

[grizzled steeple]

If ya wanna code logic for the web, you either start learning WASM or JavaScript. One is more powerful and closer to hardware while the other allows you to interact with HTML and whatnot

Personally, I'd go JavaScript for the web 😉

[old flame]

You could learn a CRM like Wordpress or Django too if you wanna go fullstack and not limited to frontend/backend

[grizzled steeple]

I was more focusing on the frontend part. For the backend you can go all sorts of languages. Tho if you only want to learn one language and wanna do web, then JS is kinda your best choice. Love it or hate it (and no TS is not it's own language, it's just JS with sprinkles on top)

[old flame]

better learn typescript over javascript any day

basically its own superset as to how c++ is to c

[frozen flame]

Cpp is not a superset of c

This was true about 25 years ago, it is not anymore

[molten oracle]

Technically, it still is.

Although it's not strictly a superset, there's some stuff in C that's invalid in C++, but it does not change the fact that C++ still adds more to C.

[peak acorn]

Im pretty sure that means it's not a superset at all

[molten oracle]

I mean there was a dedicated wikipedia page for the entire debate iirc

https://en.wikipedia.org/wiki/Compatibility_of_C_and_C++ found it

[frozen flame]

If the superset doesn't compile the original language then it cannot be a superset

Regardless of what the keyboard warriors on Wikipedia think

[old flame]

I mean i can use c++ compilers to compile c

depending on what I write ig

and which compiler I use

(looking at you, msvc)

[frozen flame]

Yes that's exactly the caveat that makes it not a superset lol

[molten oracle]

It does compile the original language, just an older version.

Which leads to newer versions of the original language capable of having more features than the not really but kinda sorta superset

[frozen flame]

You've just described "not a superset"

[delicate schooner]

Heyyy
Quick question:
I'm trying to compile a c programm using a makefile, and it works perfectly when the code is in the same folder as the makefile, but when I move it to a different folder, the makefile being in a parent folder, the dependencies break, even though all files are properly linked
Does anyone know why?

[old flame]

is gtk.h a fil in your current project tree ?

wait no its not

[delicate schooner]

no, it's a library I installed

[sour moat]

Did you installed the gtk development files

[delicate schooner]

yes

[old flame]

since it works when all files are together it appears so

[delicate schooner]

here is the makefile ```
CC=gcc

[old flame]

well first thing I notice is that in your screenshot the gtk part of the command isnt present

[keen sorrel]

Run that pkg-config manually. It appears to be empty here

[delicate schooner]

ikkkk, but it's with this make file, sooo I've no clue why it doesn't show up

[keen sorrel]

Makefile shell expansion syntax is $$(shell stuff) not backticks. Nvm backticks also works, but it does mean it will get repeatedly launched instead of evaluated once with $$ syntax

[old flame]

is this makefile a template you modified, or you wrote it ?

[delicate schooner]

wrote most of it, based on a teacher provided template

[delicate schooner]

the output seems fine

[keen sorrel]

https://www.gnu.org/software/make/manual/html_node/Simple-Assignment.html

You may want to read this page and make the appropriate adjustments. Backticks for command substitution isn't described in the manual at all. The shell function is what the manual describes for calling shell commands

https://www.gnu.org/software/make/manual/html_node/Shell-Function.html

[delicate schooner]

ok, thanks, i'll go through it

[sour moat]

How do I learn filesystem of a unmounted device in linux / c ?

[delicate schooner]

ok, solved, thank you
it was a mix of shell expansion and a flag not working properly together

What's the current state of ESP32 and does the ADC still suck ass?

Coming from Arduino and looking for something simple, cheap and wireless for IoT stuff. From what I seen the 12-bit ADCs on ESP32 WROOM-32 suffer from non-linearity, deadzones of 100mV in the lower and upper range, calibration, Vref accuracy.. worse than the 10-bit on the Uno and Nano. The ESP-S3 supposedly doesn't have the deadzones and has better hardware ADC calibration but can someone confirm that? Also how trustworthy are these devboards on AliExpress? I usually get everything else from there and have no issues so far.

[keen sorrel]

File systems may be identified by a magic number present at a fixed location (usually close to the start). For example NTFS has an 8-byte magic number NTFS at byte offset 3. Idk if every fs has got a magic number, but they usually do.

[neon oriole]

while i still think that test driven desingn (tdd) sucks monkeyballs. i found yet another reason to dislike it ,... im writing some tests atm (after the programming has been done, and the project is sufficiently interlocked with its own components that creating a test basicly means writing mocups for every other part of the program (and thus rewriting the whole program , but to facilitate a single test, and this for every part... now , if the project itself is complicated enough to warrant writing tests , and the mocups for those tests are in fact the program again minus the to test part... wouldnt that make the tests complicated enough to warrant writing tests for... 😄 no id like to see some TDD guru try to write tests to the 3 or 4th order of the actual code first before anything else 😄

[neon oriole]

you could always sidestep the deadzone by making a select that switches between a 1/100 and a 1/1 voltage divider , and if the final result on the adc would be 20mv and thus smaller than 100mv select the 1/100 divider and bump up the 20mv a 100fold resulting in an acurate voltage after the divider of 20mv

[neon oriole]

lsblk -I 8,259 -o name,path,partlabel,label,fstype,fssize
lsblk  -o name,path,partlabel,label,fstype,fssize #for al devices

[keen sorrel]

I hate tests as much as the next dev, but you didn't follow TDD. The complexity of adding tests as an afterthought like you're doing is exactly why TDD is so advised.

[neon oriole]

i didn indeed because i wrote the tests afterwards to begin with, but i tought when done well id like to see someone come up with this beforehand ... as i would have tought well actuall these tests need tests 🙂

[keen sorrel]

speaking of testing, I've finally figured out how to use the MPSoC VIP. Configured the interrupt controller and tested a manual interrupt

[neon oriole]

its like a watch, you can make a test for every gearwheel inside individually but once you want to test if they interact correctly , and see if the solar eclipse indicator is working okay , your mocking up the rest of the watch again to test that functionallity 🙂

[keen sorrel]

You might need to take a course on testing or something. Unit tests and functional tests are just separate efforts. If you need to mockup the entire rest of your system to do every functional test, you've done something really wrong.

The entire point of TDD is to ensure the very design of your product takes testing into account

[neon oriole]

since every small piece depends on one or more outcomes of other packages , and not linearly the easiest way to create the mocup would be to rewrite the original code that would have created the object in the first place... closest thing i can compare it to is to a sysfs subtree parser, you can write tests for each individual small parser, but as soon is you want to test if a node is parsed correctly , there is nothing to compare it against that is less cumbersome and less error prone than to compare it against another parsed version of the same original sysfs subtree

[keen sorrel]

Please just take a course or study someone else's tests ideally relevant to what you're doing. I'm not experienced enough to try to teach you how to properly build tests or correct your misunderstandings. Test methodology is a very wide topic anyways so even if I was more experienced I may still not know the most ideal test method for whatever you're testing.

[old flame]

the point of TDD is that you can write tests for your interfaces/functions/whatever else BEFORE implementing the thing itself, so you already know the outcome your implementation should result in before writing any code

You dont always have to follow it, i dont even myself since I like to write code while I have an idea but I usually end up wasting time writing and testing the code if i write the tests after everything

Plus thers instances where writing tests after writing code can falsify your results because now the tests are most likely more tailored towards your implementation rather than something more generalised and less biasd towards a specific implementation

Hey folks, has anyone tried to build up or use a combo of open source libs/tools for ID/Passport data scanning off images? Does not require to be rock solid as for KYC/legal reasons, i'm looking into it for auto-completion reasons for a form as a UI/UX aid for our users so they don't have to fill it in all by hand.

cursory search has not been very encouraging and for now we are using a 3rd party API. but things are getting pretty costly and we are thinking of building out something that we host ourselves.

[old flame]

There is at least 1 open source tool that can do it, however its macos only and hasnt been updated in 9 years. My guess is there are legal problems to making tools like that in the open

[old flame]

btw, if theres any x86-64 nerds in here: i tried to reimplement strcmp in assembly, kinda looks like this

section .text
    global _ft_strcmp

_ft_strcmp:
    mov rax, 0 ; make sure thats reset
    mov rcx, 0 ; make sure thats reset
loop:
    mov al, BYTE [rdi] ; take char at current position into 8 bit register
    mov cl, BYTE [rsi] ; take char at current position into 8 bit register
    cmp al, cl ; compare em
    jne end_loop ; end if they dont compare
    cmp al, 0 ; first char is null ?
    je end_loop
    cmp cl, 0 ; second char is null ?
    je end_loop
    inc rdi ; increment pointers
    inc rsi
    jmp loop

; useful info about movzx, and alignment issues ; https://stackoverflow.com/questions/22621340/why-cant-i-move-directly-a-byte-to-a-64-bit-register
; https://www.felixcloutier.com/x86/movzx
end_loop:
    movzx rax, al ; this moves al (8 bit register) to rax (64 bit register) by setting the rest of the register to 0
    movzx r10, cl ; same thing here cause we cant sub 64 bit reg with 8 bit reg (alignment)
    sub rax, r10
    ret

Is there any way to optimise this and kinda make it look better ? It does behave like the original function so far

[opaque terrace]

oh there are like a bunch of libraries and tools that are easy to google. The problem is that they are more general OCR stuff and I have not found any more ID/Passport specific stuff. I don't need a ready solution, just somethign that's geared into that direction and might require training and stuff, but that's something we can do.

[old flame]

That’s lucky, I wish it was free for vup 😭

[orchid gyro]

if i saw this i would just give up
i would call this a "phantom error" because of how complicated it is
you should recode the bits it mentions or take the hard path and debug
i like to call them phantom errors because its either a ghost causing the error (making you recode it) or just really complicated

i made little snippets of code to plug into my browser and it had an error I couldnt debug, I recoded it and it worked!
had no i dea what it was, the code is the same as the error-ridden one.
ghosts man, they come when you are stressed

[keen sorrel]

I mean it's kinda understandable lol. People working on $300-$2000 zynq boards would be seriously put off by $3000 software to program it. If someone is working on a $9000-18,000 vup board, $3000 software could be considered just a part of the cost.

[ruby pagoda]

Oh it’s certainly understandable but definitely annoying at times

I wish it was free for 7 series the most

generic OCR is your best bet if you want it for free, or google mlkit text recognition https://developers.google.com/ml-kit/vision/text-recognition/v2 if you talk about Android/iOS.

We explored this at work, and for actual ID documents, we ended up going commercial 🤷‍♂️

i mean mlkit can give you a pretty good description of the actual photographed item, and then you just need to figure out what is what

[cloud knot]

yes. that is how most of the software does it. Or have a CLI application run 24/7, with sleep() used to wait. But cron is imo a better choice if the cost of the setup is low enough - i mean setting up database/LDAP/messaging connections.

[cloud knot]

and for generic solution, you have to go for the base project used by mlkit - tensorflow

27.5 is boot loader lock bits. That's not the place to be looking for the word size. Section 8.2 is in-system reprogrammable flash memory.

Since all AVR instructions are 16 or 32 bits wide, the Flash is organized as 2/4/8/16K x 16

Please use the up to date datasheet from the manufacturer if you're going to discuss it

[sudden cosmos]

think the issue is the conversion to string before writing to file, you should either write it in binary to the file or encode it in some way you can decode it again after reading it out of the file.

like if you want the file to remain ascii, you should encode it with something like base64. unless python has some way to decode the string representation back idk if it does

ah i guess there is ast.literal_eval(bytes_string) if you want to convert back from what you've written to the file into a bytes object

[neon oriole]

depends on the type of game , and what you are willing to ofload to faster langs... like imagine a (whats the genre collecting things in the 3d world that is persistent with a million items and combinations) where every item is having to be programmed in c , it would bump the price to new hights (all them c programmers arent cheap) while with python doing alle the items would be really fast to develop comparitively , the modding community would love it , and you can still do the core engine and network code in c ..

but if its as good as it promisces to be maybe mojo is fast enough to also do that part ?

mojo is the name for python++ except that it makes things faster not slower :P\

[frozen flame]

Lol mojo

you're writing in UTF8 and reading as bytes, should probably sync those up

I'm not sure how literal eval factors into this though?

[neon oriole]

just because my eye fel on it , but did you know f.readlines() is the default so py lines = [line.strip() for line in f.readlines()] is identical to : py with open(file,'rb') as f: lines=[l.strip() for l in f] and that this wont remove empty lines as far as i know. but this will: ```py
with open('main.py','rb') as f:
lines=[l.strip() for l in f if l.strip() != b'']

[sudden cosmos]

because str(bytes) destructively converts bytes to a string repr of it

[frozen flame]

It's the same as str.decode / bytes.encode

[sudden cosmos]

but it would be more proper to do it like e.g.

with open("fb.sgres", "w+b") as f:
    f.write(base64.b64encode(rsa.encrypt("True".encode(), _secure_enc_key_publ)) + b'\n' + base64.b64encode(enc_password) + b'\n' + base64.b64encode(enc_username))

with open("fb.sgres", "rb") as f:
    lines = [line.strip() for line in f.readlines()] 
    dec_password = base64.b64decode(lines[1])
    dec_username = base64.b64decode(lines[2])

[frozen flame]

I'm on mobile so reading code is an awful experience but it seems to me that you're writing an encrypted blob and then trying to read it as though individual sections are encrypted rather than the whole thing

[neon oriole]

you can also benefit of my remark so it seems ,. f.readlines is the default so you can drop the .readlines()( 😛

not that using it is wrong, but les to type less to read is easiier to plow trough code

[sudden cosmos]

>>> pw = "mypw"
>>> bytes(pw, 'utf-8')
b'mypw'
>>> str(bytes(pw, 'utf-8'))
"b'mypw'"
>>> savedpw = str(bytes(pw, 'utf-8'))
>>> import ast
>>> ast.literal_eval(savedpw)
b'mypw'
>>> savedpw == bytes(pw, 'utf-8')
False
>>> ast.literal_eval(savedpw) == bytes(pw, 'utf-8')
True

he's saving string literal bytes to the file I think

instead of just the bytes

[frozen flame]

literal eval has no place here

[sudden cosmos]

is there another way to convert the string "b'mypw'" back to the bytestring b'mypw' ?

[neon oriole]

yeah python3 and bytes ,... some things were easier to grasp with python2

[sudden cosmos]

but yes using eval is janky which is why i suggested b64 encoding it before saving it to the file instead

so it remains ascii but doesn't need eval to decode

[frozen flame]

you should not have this string in the first place, which is one of the first things wrong here

[sudden cosmos]

yes that's what i said, "the issue is the conversion to string before writing to file"

[frozen flame]

right, but like i said thats one of many issues

the biggest one is that he's trying to read an encrypted blob as if it were unencrypted

actually i just took a look on my laptop and i might be wrong on that

curses on mobile formatting

(honestly id just do the one blob instead of multiple, but whatever floats his goat i guess)

with open("fb.sgres", "wb") as f:
    f.write(rsa.encrypt(password + '\n' + username, _secure_enc_key_publ)

with open("fb.sgres", "rb") as f:
    password, username = rsa.decrypt(f.read(), _secure_enc_key_priv).split("\n")

[frozen flame]

this works too

[sudden cosmos]

i just like ascii files so you can see what you did without hexdump lol

[neon oriole]

not that its that important but that way if you know the username you halfway there of decrtypting it ,.. ?

[frozen flame]

i wouldnt encrypt a username myself but that seems to be what theyre going for

[sudden cosmos]

looks like they're hacking together some kind of credential manager

better than just keeping them plaintext like i do lol

marginally, if the key is right there

[frozen flame]

fwiw those tend to leave things like usernames/websites unencrypted too, to provide them to the OS for tooltips lol (not always usernames, but certainly other metadata)

[sudden cosmos]

huh didn't know about this encoding this is kinda handy

>>> b'\x35\xe5\xFF'.decode('iso-8859-1')
'5åÿ'
>>> b'\x35\xe5\xFF'.decode('iso-8859-1').encode('iso-8859-1')
b'5\xe5\xff'

oh that's just latin1. but yeah apparently it can encode all of 0-255 as characters that can be decoded back

[fringe spade]

ty guys

[fringe spade]

this worked

I just needed to modify the code a bit

  with open("fb.sgres", "wb") as f:
            f.write(rsa.encrypt(_secure_password_c.encode("utf-8") + b'\n' + _secure_username_c.encode("utf-8"), _secure_enc_key_publ))
  with open("fb.sgres", "rb") as f:
            _secure_password, _secure_username = rsa.decrypt(f.read(), _secure_enc_key_priv).split(b"\n")

Did they not just days ago deprioritize flutter's multiplatform goals?

Maybe mobile and web is close enough to some. RIP desktop apps

[cloud knot]

it exists for desktop too. and Kotlin multiplatform and flutter coexisted for some time, it's different use cases

Flutter is more rapid, Kotlin multiplatform is more native (if you want to go that way)

[keen sorrel]

I'm aware of that, I've used it. It appears you haven't heard the news of the flutter team being restructured and desktop support improvements being removed from the roadmap a couple days ago

Or rather two weeks ago

[cloud knot]

well restructuring is more or less "we get rid of expensive employees in US and push the work to lower paid EU counterparts"

[fading osprey]

if anything, the EU counterparts are usually just as expensive, think further east or south

[cloud knot]

not really, we talk about $140k for US vs 70k in EU for same position

[fading osprey]

i guess that depends on the company

and the position

[cloud knot]

Python team was asked to move to Germany, Flutter is going to Mexico team etc.

And in the end, for same position in US vs EU, you can usually expect salary drop of 30-50% for literally same job, before taxes even come into play

[silk eagle]

I think if its the same people on the team they'll also need to pay US taxes

I forget exactly how that works

[restive ore]

since when can websites block inspect element and right clicking?

[cloud knot]

they technically moved devops positions to another country. Income taxation of person who moved to that other country is sadly a personal issue of that employee, the employer doesn't have to pay anything in US.

[cloud knot]

right click since forever (oncontextmenu). Inspect element can't be blocked, but they can make your life miserable for a while by calling the debugger call which stops execution. But you can disable debugger globally for the tab

[silk eagle]

I mean the employee would have to pay US taxes if they're a US citizen even if they live and work in another country I think (unless they renounce their US citizenship/plan on never going back to the US)

[restive ore]

i found a way around, control shift i didn't work but control shift j did

[cloud knot]

wait you meant some keyboard shortcut for it ? i never did inspect element via keyboard, it was either mouse context menu or by clicking on the icon on debugger panel 😄

[restive ore]

oh ok. also if anyone is curious this is the website that blocks right clicking and control shift i shortcut https://www.newsunzip.com/articles/what-its-like-to-work-inside-nycs-windowless-long-lines-skyscraper/

[cloud knot]

yeah, they literally just override oncontextmenu for right click

and this for onmkeydown:

            document.onkeydown = function(event) {
                event = (event || window.event);
                //alert(event.keyCode);   return false;
                if (event.keyCode === 123 || event.ctrlKey && event.shiftKey && event.keyCode === 73 || event.ctrlKey && event.shiftKey && event.keyCode === 75) {
                    if (show_msg !== '0') {
                        show_toast('inspect_elem');
                    }
                    return false;
                }
                if (event.ctrlKey && event.keyCode === 85) {
                    if (show_msg !== '0') {
                        show_toast('view_src');
                    }
                    return false;
                }
            }

a completely idiotic naive approach, as if one can't call those functions via the browser menu through mouse

[neon oriole]

Havving used quite a bit of langs and of course they are subdividable in many ways , but the one im curiouse about is this split where one is way more common and popular then the other, yet i dont see the benefit for it, so : { } or no {} there are only 4 languages that i know of thta dont use the {} as a code block designator : python, VHDL,COBOL,BASIC. and 3 of that are not really applicable to computer programming today.
Weird thing is : Other than opening up allot of discussions for where they should go , i dont see the benefit of using them. Okay the other option is forced indenting like python does so you cant do: ```
def function(){
verry='verry'
flat='structure'
}

so since every other lang uses them (while they could be used for something else (thers never enough symbols to use) they must geve a huge benefit some how or enable you to do stuff theat not using them prohibits. problem is that i cant seem to find any. nowim defenetly not the lifetime hardcore programmer that some of us are , so what are the benefits for using {} ?

[cloud knot]

i will never accept languages which use indentation for code block demarkation. It is just way too prone to errors

using indentation for such task is a bad idea in a world where we can't even agree if we use tabs, 2 spaces, 4 spaces or 8 spaces 😄

plus using {} allows you to do crazy oneliners, of course at expense of readability

[neon oriole]

i more often forget to open the { then i forget to indent 🙂 (closing the } is fine (as i automaticly // blockname behind it to indicate what im closing

[sudden cosmos]

you can't arbitrary create a scope in python can you? everything is just function scope?

although i rarely use that even in C++, usually scope my variables to the function anyway

some ideas just catch on and nothing else provides enough of a benefit to justify switching to it i suppose

javascript has to have them though since it's sent over the wire as text

[neon oriole]

i think i've have the final sane answer on that but i wouldnt force anyone to change his or hers habits on that since there is a way currently in use that all of them are vallid as long as you dont mix them.. (ps: the only sane way i found is 😛 it makes sence to use a diffferent char for indent and for allignment , and the only guarantee allignment keeps alligned is by using spaces for that , so tabs left for indentation) (there are more reasons but...)
also how is indentation more prone to errors ?

[cloud knot]

with {} you have clearly demarkated start and end. with indentation, let's say you have something like

python code line 1
  python code line 2
  python code line 3
  python code line 4

you go stupid and you delete the indentation on line 3

python code line 1
  python code line 2
python code line 3
  python code line 4

poof, completely different code

[neon oriole]

yeah you mean bytes or bits over the wire i guess wich in turn makes it not really a matter of have to since you can use anything to indicate end of block at that point. but i get your point ,since javascr has to be typed ... but even then it would only be a problem if a space/tab were a bunch of zeroes indistiguishable from datafail

[cloud knot]

with {} you do:

code line 1 {
  code line 2
  code line 3
  code line 4
}

you delete the indentation, code executes still same:

code line 1 {
  code line 2
code line 3
  code line 4
}

and i mean unintentional change in code which changes the execution, because you went from one valid code to other valid, but functionally different code, just because you deleted some indentation by mistake

[neon oriole]

hu ? im missing that because in the one you decide do delete the significant part and in the other the insignificant part , you should delete the { or the } there ```
code line 1 {
code line 2
}
code line 3 {
code line 4
}

code line 1 {
  code line 2

code line 3 {
  code line 4
}
```

[sudden cosmos]

that and it's at least 3 extra bytes per line (or does it accept tabs?) to transmit, idk with javascript they always remove all whitespace before sending it

[neon oriole]

seems equally prone to errors there

tab is just a single character just like (any/most) others

[sudden cosmos]

whitespace would probably compress out pretty well if you like gzipped it though maybe that's not a big deal

[neon oriole]

that is why you can havve your editor pick how many space to use for a tab

[cloud knot]

no, because your case is invalid code. In case of Python, that is still a valid code

in the end, it is down to personal preference, you can always just use python if you like indentation block languages 🤷‍♂️

[neon oriole]

okay : c will fail to compile, javascript wil just deal with the invalid code and run with it

yeah my point was also more like if we'd have {} availeble for other syntax stuff we would not have to doe the weird constructions we now sometimes do

[sudden cosmos]

been a minute since i worked with javascript but i thought it crashes if a document is invalid

cause it has to parse the whole document first even if it doesn't run

[neon oriole]

with the amount of javascript used today,.. that would have made the web unusable

[cloud knot]

why would C fail ?

#include <stdio.h>
int main() {
    double a, b, product;
    printf("Enter two numbers: ");
    scanf("%lf %lf", &a, &b);  
 
    // Calculating product
    product = a * b;

    // %.2lf displays number up to 2 decimal point
    printf("Product = %.2lf", product);
    
    return 0;
}

and

#include <stdio.h>
int main() {
    double a, b, product;
printf("Enter two numbers: ");
    scanf("%lf %lf", &a, &b);  
 
    // Calculating product
    product = a * b;

    // %.2lf displays number up to 2 decimal point
    printf("Product = %.2lf", product);
    
    return 0;
}

are functionally identical programs

def multiply_numbers():
    num_1 = float(input("Enter the first number: "))
    num_2 = float(input("Enter the second number: "))

    product = num_1 * num_2

    print(f"Product of {num_1} and {num_2} is {product}")

and

def multiply_numbers():
    num_1 = float(input("Enter the first number: "))
    num_2 = float(input("Enter the second number: "))

    product = num_1 * num_2

print(f"Product of {num_1} and {num_2} is {product}")

are not (not sure if the print statement would crash or not, i did very limited python coding in my life)

[cloud knot]

document parsing is browsers job. Javascript will not crash because of bad HTML structure, as it is not going to interpret it in the first place. It will work with whatever DOM structure browser created from the HTML document

code could fail if it expects some elements to be present and they aren't, but that is another story 🙂

[sudden cosmos]

i mean in his example where he had unbalanced braces

[halcyon lintel]

hi there, so ive been working on php lately and right now, im encountering this error
Fatal error: Uncaught ValueError: Path cannot be empty in E:\5thSemesterWebDevProject\imgUpload.php:26 Stack trace: #0 E:\5thSemesterWebDevProject\imgUpload.php(26): getimagesize('') #1 E:\5thSemesterWebDevProject\myassignments.php(2): include('E:\\UniversitySt...') #2 {main} thrown in E:\5thSemesterWebDevProject\imgUpload.php on line 26
where i change the file name in query selector in this
let input = document.querySelector('.imageFile');
the code on that line 26 in pfp is this
$check = getimagesize($_FILES["image"]["tmp_name"]);
does anyone know what the issue could be here?

[cloud knot]

unbalanced braces would fail in JS too

[sudden cosmos]

idk about in the browser i would think you'd get a console error about the script tag being invalid, i was just thinking about in the nodejs interpreter

browsers are obscenely fault tolerant with bad documents though yeah

[cloud knot]

you should never manipulate the file input, you probably set it to invalid value and nothing got uploaded. print your incoming data, but most likely you uploaded nothing

[halcyon lintel]

yeah thats what seems to be happening. without the file name change, it works fine. but changing the name generates that error.

the reason i need to change that name is because of the input form i already generated

that "browse" and dragover function relies on that name alteration.

[cloud knot]

that must be some weird library

[halcyon lintel]

oh btw, the original name of that element is ".uploadForm input" and im changing it to a specified name mentioned above

[sudden cosmos]

is it just a transient state while user is editing things? don't call the function until interaction stops and catch and handle the error so it doesn't bubble up

[cloud knot]

https://developer.mozilla.org/en-US/docs/Web/API/HTML_Drag_and_Drop_API/File_drag_and_drop this is how you do it, you process the obtained file and submit it yourself, for example by converting it to base64 or uploading the blob ?

[neon oriole]

you prolly already know this but its actually html that is fault tolerant, well not really it has defined rules , what it does in such a case.. liek with : html <p>some text<br /> <h1> my title</h1> some more text </p> if you for instance forget to close the p tag it wil do it for you like : ```html
<p>some text<br />
</p><h1> my title</h1>
some more text
</p><-- will bi ignored then

it will make the second part a floating piece of text not in tags , because a <h1> tag may not be inside a <p> tag so it will close it for you 🙂

srry was wrong it will also reopen the ptag right be fore the other one so : ```html
<p>some text<br>
</p><h1> my title</h1>
some more text
<p></p>

[halcyon lintel]

ig i will have to redo it

[neon oriole]

and people wonder why their css doesnt work for the second part of the text ... 🙂

(and most teacher arent aware either

Static is fixed at platform creation and consequently at boot in the device. It has scaling, chroma resampling, color conversion, and change detection. Along with the video read and write DMA to the system's DDR4.
Dynamic can be reconfigured live after boot.

On big codes that demarcation is very much no longer clear

nah your totally right to do so, I do the same our time is limited, and some people just scroll through answer once and leave again, which is their good right.
I also do the same. want another one? https://nohello.net/en/ I use this one too 🙂 since it takes too much time.

[limpid reef]

NoHello.net, DontAskToAsk.com, and https://xyproblem.info/ are all some of my favorites.

My all-time favorite has got to be this article from 20+ years ago.
http://www.catb.org/esr/faqs/smart-questions.html

Before You Ask

Before asking a technical question, do the following:

1. Try to find an answer by searching the archives of the forum or mailing list you plan to post to.
2. Try to find an answer by searching the Web.
3. Try to find an answer by reading the manual.
4. Try to find an answer by reading a FAQ.
5. Try to find an answer by inspection or experimentation.
6. Try to find an answer by asking a skilled friend.
7. If you're a programmer, try to find an answer by reading the source code.

When you ask your question, display the fact that you have done these things first; this will help establish that you're not being a lazy sponge and wasting people's time.

Use meaningful, specific subject headers

On mailing lists, newsgroups or Web forums, the subject header is your golden opportunity to attract qualified experts' attention in around 50 characters or fewer.

• Don't waste it on babble like “Please help me” (let alone “PLEASE HELP ME!!!!”; messages with subjects like that get discarded by reflex).
• Don't try to impress us with the depth of your anguish; use the space for a super-concise problem description instead.

One good convention for subject headers, used by many tech support organizations, is “object - deviation”. The “object” part specifies what thing or group of things is having a problem, and the “deviation” part describes the deviation from expected behavior.

• Stupid: HELP! Video doesn't work properly on my laptop!
• Smart: X.org 6.8.1 misshapen mouse cursor, Fooware MV1005 vid. chipset
• Smarter: X.org 6.8.1 mouse cursor on Fooware MV1005 vid. chipset - is misshapen

[leaden gorge]

oh cool , I know about all 3 above those 😮 but not the catb one thats a new one 🙂 Thanks!
it sounds a bit harsh these sites, but its for the good of learning and quick answering.

[leaden gorge]

should update on 8. use an AI to explain snippets of code if coding 😄 its actually a thing I do to explain library or gain an example when sourcecode is not giving one

[spark temple]

Yeah. I’ve read that one and have shared it to people at work. It’s a little different working asynchronously.

It’s also in the Other similar problems section of Don’t ask to ask, Just ask.

[spark temple]

Really enjoy this. I say, if you can’t provide your work / steps, research / links, or where you looked, then you haven’t done enough to understand the actual problem you are facing.

A good question provides the right scope to help you obtain the answers you seek.

[haughty oyster]

I just saw that exact thing on a different server haha

[lethal pike]

Does someone know how to host a website on a own server and make the website public?

[keen sorrel]

What in particular are you having trouble with?

[lethal pike]

How I should host it so have a Proxmox Server, I could run a virtual machine or a container. And how I can connect my website to my domain

[midnight wind]

is it a static site? web app?

as for domain, you just create a DNS record pointing to your IP

you can use cloudflare to hide your IP and use their proxy

[lethal pike]

It‘s just a porfolio of my projects

[midnight wind]

ok? but still what type of site is it

does it neeed databases? a bunch of html, css (static), etc?

[lethal pike]

Yeah

[midnight wind]

so it's a static site?

[lethal pike]

Yeah

[midnight wind]

fyi you can host it for free on cloudflare pages without having to mess with hosting it on your own server

[molten flicker]

That's exactly what I did say 😭

[leaden gorge]

Well let them be sour 👍🏻 and ignore them until they have anything useful to say

[spark temple]

It also depends on where they host it too. If it’s in an ISP the IP address will roll at some point.

Theres a cron job script that will update the IP address if it changes.

Also, the database really shouldn’t matter as you aren’t exposing that to the internet. I’d only make it accessible locally and just do a vpn / ssh tunnel back to my network and then connect to the database that way if I needed to do remote work.

[molten flicker]

They got the mods of this particular server in on it, that's the thing.

Some people are just so aggressively inefficient

[midnight wind]

yeah, or use a dynamic dns service

I was asking about database since that still would need to get setup on the server

instead of just spin up nginx/apache

[spark temple]

If you’re hosting yourself, they most likely are looking to save some money. Otherwise, host on a cloud provider.

[midnight wind]

There's a bunch of free ones. I used a script for cloudflare dns

Uhhhh guys git isn't working anymore for me and I have no idea why :( I'm a programming noob so I've been trying to learn about git, and I changed some of the default settings, then I tried changing the default directory and I think that might've fucked something up. Github desktop doesn't recognize any of my repos anymore and I can't use git commands in git bash. Pls I need help :(

I even reinstalled git

I get "fatal : unable to access 'filepath' : invalid argument" as the error. The filepath seems to be the git config but idk it doesn't seem like the right one actually

Ok nvm I got it working 😌 I had to change my environment variable because it had a really scuffed path because I definitely misunderstood a git command

[clear sonnet]

Bro wtf.. Epic has some nerve to tell us how to code C++.

https://dev.epicgames.com/documentation/en-us/unreal-engine/epic-cplusplus-coding-standard-for-unreal-engine?application_version=5.3

Section in picture.

[cloud knot]

those are coding standaards if you want to contribute to the engine. It is their project, they set the rules

[clear sonnet]

It clearly says here at Epic Games they follow these guidelines. Meaning anyone wanting a job there won't unless u follow these guidelines and doubt any plugins or scripts you submit for the asset store will be accepted if it's not adhere to their coding standards.

To ignores these as simple "eh it's just epics thing" isn't great for anyone wanting to be part of the industry or anyone who is in the industry that might eventually have to adhere to the guidelines if the company decides to use their engine.

It's saying u either write pseudo code that won't offend anyone or just don't have a future in the industry

[fading osprey]

that is literally not what it is saying, it is not that deep, those are their coding standards. in fact, the first two sentences in the document are literally

"At Epic Games, we have a few simple coding standards and conventions. This document reflects the state of Epic Games' current coding standards. Following the coding standards is mandatory."

Now, the way I interpret this, is very much "following the standards (at Epic Games) is mandatory, and this documentation clearly lays those standards out for you to prevent confusion.

you do not have to follow them, if you do not work for Epic Games, though it will help you get better support if you do because they follow the internal guidelines everyone is beholden to at the company, meaning all the people who actually follow them are more likely to be understood....

I am just before writing this right now refactoring old code of mine that used slave, master, blacklist and whitelist to use more modern terminology, I agree that some of the things they wrote in there are slightly on the wilder side of "why though", like abort, execute, or native, but for the most part it seems to be entirely fine

1. The connection isn't encrypted

[gritty mirage]

could someone help me with fixing this?

Commit -> GitLab CI/CD docker image build -> GitLab container registry -> Openshift

the problem is that locally the image from gitlab registry is running with no problems

but deployment fails with this error

[nocturne galleon]

yeah people were uploading bad crap so i purposely broke the website

also did a very, very bad command and had to reset the whole thing, was able to save the project folder from that burning building of a OS

*made everything be owned by a user that wasent root, had no ssh access, and the only connetion i did have was a SFTP connection i forgot to close. Used that to download my project and let the os burn down

[fringe spade]

᲼

[old flame]

If you can, check your permissions on your deploy server. I had troubles locally with permission mismatch with some being of the actual user, and node_modules and other files/folders being owned by root

[cloud knot]

if i am reading it right, your issue could be caused by Openshift, as it is running images as non-root random user. You could have those folders existing in the image, with set permissions for root, which obviously means the docker image commands under non-root user can't create files you want.

And locally it runs because i guess you run it under Docker and not Openshift ?

[fading osprey]

I have a feeling I might have broken something 🤦

[cloud knot]

you are obviously sending a JSON object into a ParseInt method

[fading osprey]

Yes, however said JSON object was instead supposed to be a simple 0-0, which does actually get parsed by the utility method properly

does anyone know gnuplot here? id want to load a column from sql, evenly space all the points (or the last 125) from that column along the x axis, and then have te columns values be the Y axis.. i have made a little bash script, but its very broken, and im really struggling to understand gnuplot and its requirements.
this is my script tha ti have glued together:

# Set up variables

output_file="LuftFeucht.png"

# Query the database and format the output as space-separated values
data=$(mysql -u root -ppasswordhereiguess -e 'Select LuftFeucht from Sensoren' Mars | tr '\n' ' ')

# Write the data to a file
echo "$data" > temp.dat

num_rows=$(wc -l < temp.dat)

# Generate the Gnuplot command file
cat << EOF > plot.cmd
set title "$graph_title"
set xrange [-0.5:{NUMROWS}-0.5]
set yrange [*:*]
unset key
plot "temp.dat" using 1:2 with linespoints title "$column_name"
EOF

sed -i "s/{NUMROWS}/${num_rows}/g" plot.cmd

# Plot the data using Gnuplot
gnuplot -persist plot.cmd

# Convert the graph to PNG format (optional)
convert -density 300 plot.ps $output_file

# Clean up temporary files
rm temp.dat plot.cmd plot.ps

this complains about undefined Y values.

YAML is trash change my mind

On a related note anybody know how to stack multiple x-field-extra-annotation in OpenAPI generator without having to do \n (which works but is ugly):

          type: integer
          format: int64
          example: 10
          x-field-extra-annotation: "@jakarta.persistence.Id\[e-mail](strategy = jakarta.persistence.GenerationType.IDENTITY)\[e-mail](name = \"id\")"```

  - making
  - a
  - list
``` results in buggy crap so that's not the answer

The prior gives me this at least

@jakarta.persistence.GeneratedValue(strategy = jakarta.persistence.GenerationType.IDENTITY)
@jakarta.persistence.Column(name = "id")
  private Long id;```
but that's expected

Note the missing tabulation though

[silver furnace]

I can also make them on one line but thats uggo. Can't manually format the java file since it gets auto-generated -.-

[cloud knot]

this is pretty much a YAML question, no ? https://yaml-multiline.info/

[silver furnace]

Yeah and a bit of an openAPI gen question too. Because technically should be separate additional annotations.

I just space delimited them for now. I mean it's not the end of the world. It's an autogenerated schema class that looks messy on its own

I was told I shouldn't directly use schemas it as Spring JPA entity classes anyways. This is temporary measure.

[cloud knot]

unfortunately what happens with x- items is literally up to the tool which uses the OpenAPI spec, as anything x- is a non-standard extension

[cloud knot]

have you tried what these guys did ?

[silver furnace]

Same effect as \n but this is honestly what I'll do for now, thanks. It gets rid of outer quotes so I don't have to escape ones in the annotations. Also makes the REST API yaml look way cleaner so that's something

    Student:
      type: object
      x-class-extra-annotation: |-
        @jakarta.persistence.Entity
        @jakarta.persistence.Table(name = "student")
      properties:
        id:
          type: integer
          format: int64
          example: 10
          x-field-extra-annotation: |-
            @jakarta.persistence.Id
            @jakarta.persistence.GeneratedValue(strategy = jakarta.persistence.GenerationType.IDENTITY)
            @jakarta.persistence.Column(name = "id")
        username:
          type: string
          example: abominableCider69
          x-field-extra-annotation: |-
            @jakarta.persistence.Column(name = "username")
        firstName:
          type: string
          example: John
          x-field-extra-annotation: |-
            @jakarta.persistence.Column(name = "first_name")

so i have an idea of a project to do (export Plex library metadata into Kodi compatible NFO files), but can't decide on development itself.

Should i use it an excuse to learn a new language (Rust, Go or Python?) or do it in something i am fluent in.
Should i do it as CLI, desktop or web based UI ?

Hate making design decisions LOL

[forest hemlock]

What languages are you fluent in?

[cloud knot]

lately i did mostly frontend, thus JS/TS & other web technologies. Also did a bunch of Java/J2EE, PHP. I wouldn't count my use of Pascal from 2 decades ago as a relevant skill these days. Also did some of the Android & iOS native technologies, so light Android Java/Kotlin & iOS Objective C/Swift skills (but only very light, to get me by to create Cordova plugin interfaces between the native code and JS)

also dipped my toes a little bit into Dart/Flutter

also probably forgot random small technologies we used/tested at work along the way

[forest hemlock]

Can you think of any solid reasons you would need a new language?

[cloud knot]

reason is why not. One can never know when it will come handy

[forest hemlock]

Well, learing a new language is a time investment, is spending that time to learn a new language worth it? Or would you rather spend that time mastering a language you already know?

[fading osprey]

It's always handy to learn a new language, never know when it might come in useful

[cloud knot]

i guess i could still do Kotlin multiplatform, even if i don't want to make mobile platforms, thus allows me to learn the Kotlin language & Compose multiplatform functionality before i might need to use it at work. Not sure it is ideal toolkit for this use case, but oh well, not my problem /s

[forest hemlock]

Well if you did a bunch of java and just want to get a working program out the door you could just use that

[fading osprey]

If they already have to learn Kotlin MP for work at some point anyway, why not learn it now, and be more productive at work later when they are more experienced? Seems like a reasonable time investment

Need the collective brain on a problem. We are recording an mp3 voice message in the webapp via the https://github.com/samhirtarif/react-audio-recorder , that works just fine. We get the file to the server, mime type is correct ( audio/mpeg ), file name has .mp3 extension. I upload it to whatsapp media endpoint, it accepts it. Then I send audio type message ```Array
(
[messaging_product] => whatsapp
[to] => 1234546566
[type] => audio
[audio] => Array
(
[id] => 306114195907326
)

)

[cloud knot]

is this PHP ? have you checked the exact message you are sending as JSON ? Because https://developers.facebook.com/docs/whatsapp/api/messages/media/ specifies it as:
"audio": {
"id": "your-media-id"
}

So it does matter if your PHP to JSON conversion makes:

"audio": {"id":"xxxx"}

or

"audio": [{"id":"xxxx"}]

from it

[opaque terrace]

hmm

i mean other files are sending fine, but yeah gimme a sec

[cloud knot]

also https://stackoverflow.com/a/72661353

The official documentation indicates that in order to send such messages, the conversation must be initiated by the user.

could it be that your media file is the first message in the conversation ?

[opaque terrace]

no that part is handled

wall other messages work just fine, only audio has this stupid issue and Guzzle client makes it hard to debug...

[cloud knot]

you could try temporarily to upload it to a server and send link instead of id, at least to test if there is some issue with the uploaded media:

[opaque terrace]

{"messaging_product":"whatsapp","to":"+xxxxxxx","type":"audio","audio":{"id":"1507724556813303"}}

@cloud knot it does send out correct JSON format

[cloud knot]

do you have webhook set up ? Some errors are aparently only communicated via webhook

https://developers.facebook.com/docs/whatsapp/cloud-api/guides/set-up-webhooks this

[opaque terrace]

we have, but i've not been checking what arrives for it

okay, we gonna need to update some code for our gateway to process some system messages, maybe it's been sending it, but we never knew that some errors are webhook only

[cloud knot]

on positive note, the annoying part (Gradle configuration of openapi, automatic building, fetching of the OpenAPI schema etc) is done, so now i can actually start coding in Kotlin and figure out how the hell does Kotlin & Kotlin/Compose Multiplatform even works. Even if i only do a desktop app for now

[sand lily]

ive been thinking about building my own pokedex with the pokeApi in java. And as a beginning to my java script journey of course. ive bern coding backend for almost 10 months now with java. would you say building a pokedex is a good intermediate project to learn some things in frontend dev and improve my backend dev skills even more?

[cloud knot]

backend is mostly whatever you want to use. You want to have a well defined "contract" for frontend, that is the REST API and the structures in it; then you can play around with backend technologies as you progress through the skills

if you do your REST API definition well, you can replace a Java J2EE or Spring backend with Quarkus microserves running on Kubernetes, then replace them with whatever next 😄

[urban mulch]

so, I have a very specific problem with HTML
I have several audio tags in a page

Any ideas to fix it?

[cloud knot]

what do you mean by click to open the options ? Native browser menu or some JS functionality ?

if JS functionality, how do you initiate those opening of "options"?

[urban mulch]

Native browser menu

https://codepen.io/samudebug/pen/LYoONMp

I made this codepen to demonstrate

ok, so I just checked it. It's a visual bug, the menu opens only on the last one, but the "context" is for the one I clicked

i think the backslash in set is not required, thus you are sending those slashes to cloudflare as well, and they are like what are these backslashes doing in the JSON

hi guyss!!
i have learned MERN stack, want to learn nextjs can anyone suggest some good free resources

[noble plover]

powerpc assembly :p

both annoying and useless at the same time !

[peak acorn]

ADA

And if you want something useful learn go if you havent already

[acoustic pine]

Both ends up at the same spot

If it works it works

Though then there's that third cat who jumped

[nocturne galleon]

Hello! Do any1 here know about llm and python integration ?

[peak acorn]

There's lots of tools for it nowadays. If you're using OpenAI they have their own python library, there's also other stuff like LangChain for other types of ai providers.

[green matrix]

Yeah, LangChain is quite popular in the LLM space

[nocturne galleon]

Thanks! i'm trying to use an ai model offline with python, but everything that i came accross like lm studio use openai api but don't support function calling, which is important

[tardy sluice]

Hello guys, I built a native app in Unity that runs on a meta quest3 and a react app that will be hosted somewhere else.
Now I want the native app and the react app (the instance that will be opened on the browser) to talk to send messages to each other.
I do not want an external server to be involved for every transaction.
I tried WS but the HTTPS protocol (on which the react will run) will not talk to WS, and I am getting errors with the certificates hashings.
I tried WEBRTC but it seems too complex and there are not many resources out there for Unity WEBRTC with React for text.
I tried running a local server within Unity app and this approach works but the messages can only go from the native app to the quest but not the other way around.

Can someone please help me out with this problem?

[peak acorn]

You have to have some sort of process listening to a port in order to receive unsolicited messages

webrtc needs a STUN server or something im pretty sure

[tardy sluice]

yeah webrtc should work, but that is too complex and I do not want to spend that kind of time on it...
can you pelase suggest something better

[tardy sluice]

Yeah it does need a STUN server, I did use that but it didn't workout

[noble plover]

realistically turn, stun only really works over lan

for a start if you want websocket communication you almost definitely need to be using it in an insecure context, as much as that sucks

[peak acorn]

If ur on lan you can just expose a port and be done with it

[sand lily]

hey guys, im playing around with js rn (relatively new to programming, only did backend stuff like java and c#). Im trying to build a pokedex and have tried the following code. the first fetch returns an url to the Kanto region endpoint. is it possible to fetch the returned url like i did? what is my mistake here? :PepeHmm:

[peak acorn]

I dont fully understand what you are trying to do/what the api does, but fetch() and then() are both parts of async promises, so keep in mind that the program will continue while the code in those are processed in the background.
The final .then() doesn't return anything, so it's a promise<void>. If you change it to (y => {log...; return results}) you'd get closer to what I think you want. However, that is still just a promise to eventually resolve a result, if you want to use that url in the let kantoDex part, you'd need to make that piece of code asynchronous so that the code can actually pause and wait for pokedex to resolve to a result

[cloud knot]

you got two options:

1. you move your code in the callback. that is the "then" function. See the bottom of the example https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise#basic_example
2. you use async/await, if your Javascript engine supports it https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function

[spark rune]

Things have gone horribly wrong when you start vectorizing your Golang for performance gains

[peak acorn]

Like making use of SIMD functions in cpu? How do u even do that in go

[worldly musk]

Not necessarily. If your workload is math-heavy then it's a godsend

[spark rune]

The issue is Go not having to use SIMD. I try to avoid GPU and SIMD when doing Go because it usually means you’re in such a hot loop you should be using C(++)/zig/rust to get proper hardware and memory controls

[worldly musk]

Fair

@here i recently changed my personal site's color scheme, criticism?

deusvult.neocities.org

[limpid reef]

At first glance, not enough color contrast. I don't personally follow WCAG myself and I have 20/15 vision, but even I have a hard time reading the text because there's not enough contrast. https://accessibe.com/accessscan?website=deusvult.neocities.org

[fresh rampart]

Thank you; i have poor vision as well, however it is acceptably corrected with just my glasses. (i am severely near sighted.)

[fading osprey]

Coming in here with 20/20 vision, on a best case scenario dark room with bright screen.

There is no way anyone is reading that without straining their eyes, needs much higher contrast on the text. If you want light text, you can try a darker outline on the text with maybe 1px thickness and keep the existing text colour, but for anyone with any level of reading issue, the site as it stands is as good as incomprehensible

I couldn't find an app for android that can log the value of battery temperature and current consumption in a file. Is it possible to use qpython to write a logger instead?

[cloud knot]

if you want it directly in android, then you need to create an app, which has a backgrond service, which periodically does this.

Or if you don't want to do it, you can just install a home assistant companion app on your phone and let it report information to HA instance and use the data from there (not sure if it reports tempeature)

[nocturne galleon]

Thanks for the suggestion. Will check out the home assistant part.

[cloud knot]

as i said, if you want it yourself, an android app with background service which reads that data and reports it is an option

[chrome saffron]

To add to the HA discussion, these are all the stats that HA can pull about the battery:

Max update frequency is 1 minute for HA App

well it is pretty easy to read, but, node cannot find index.js, so, where is index.js located? because it isnt in the current directory

[cloud knot]

isn't the inedx.js in the Chatgpt folder ?

[cloud knot]

yeah, it requires no coding for mobile and if you got HA server already, all it takes for you to set up an action when value changes to let's say publish values to MQTT server or whatever other target

[tardy sluice]

I have a native unity app running in the background of my quest and this app will launch the browser onto this device and run in the background, and now this app is not listening to the user speech in background, and is not playing audio, how can I solve this

[jovial garden]

I got this really weird C++ error

[modest tartan]

Idk if this is right I don’t know c++ or any language but try return(main)(int); no if that will work

[heavy dew]

add )

[jovial garden]

it asked me then to add a semicolon

[keen sorrel]

That's just not valid C++. There's no way to fix it. What is your intention?

[modest tartan]

Ngl from my small I should have known you do return 0 I think

[keen sorrel]

That's assuming their intention is to return 0

[modest tartan]

It’s strange that I know that even though I have not learned c++

[keen sorrel]

That style of return syntax is widely used across languages, not even just those that are C-like

[spring cradle]

unrelated but i know that pfp, that card is so annoying

[modest tartan]

I may or may not play the deck irl

it was a pretty cheap deck to assemble ill admit

[modest tartan]

Most of the cards when I got them were at the most expensive price besides the Dino cards

[spring cradle]

oof

[modest tartan]

But I regret nothing

[keen sorrel]

What is your intention?

[jovial garden]

to end the program if the variables inputted are below the minimums in a conditional

[keen sorrel]

convention is to return a non-zero number for errors and zero for success. You can define your error numbers with an enum or just directly return an integer literal.

enum Error {
  NONE = 0,
  INVALID_INPUT = 1
};
int main(int argc, char** argv) {
  if (error_condition)
  {
    return Error::INVALID_INPUT;
  }

  return Error::NONE;
}

or

int main(int argc, char** argv) {
  if (error_condition)
  {
    return 1;
  }

  return 0;
}

[keen sorrel]

if you're trying to end the program from outside of main, you can't really. Not without it being a crash anyways.

[peak acorn]

So we have this 11k loc go file. Will break that up into a smaller file later. But anyway -- my coworker uses a mac and his vscode autocomplete and stuff is almost instant, mine takes over a second on windows. Anyone know if this is a configuration difference or mac is just magically instant at it?

[keen sorrel]

What kind of storage device is your project and user's home folder on? vsc stores intellicode data in appdata

[peak acorn]

my C drive is a p31 gold 1tb. Almost completely full, might be harming speed.
Project itself is stored on a second drive, crucial p3 4tb
maybe the two drives?

[keen sorrel]

Performance degrades a lot beyond 80-85% capacity. You can benchmark your drives and ask your coworker to do the same if you want to see how substantial the difference is. However, if you have sufficient RAM the impact of storage should lessen as things get cached. If they have apple silicon, their RAM is also potentially higher performance than yours.

[peak acorn]

They have a high end mac, m2 ultra 192gb and some huge ssd. And of course their SSDs and ram are crazy fast -- but my pc isnt a slouch either, 12600k 64gb ram. Not crazy fast, but im surprised that a file that big just turns intellisence into mush on my machine

[keen sorrel]

What speed is your RAM?

[peak acorn]

just ddr4 3600

[keen sorrel]

To put that M2's RAM into some perspective, it has 27.7x your RAM's bandwidth. It's CPU is also substantially faster. Even if your machine has no potential issues, it's still gonna be noticeably slower

[peak acorn]

Yeah im aware of the speed difference. There doesn't really seem to be a middleground though. Either its instant or its ~3+ seconds. So I figure it might just be a system config thing

Either way. Looks like it's just system speed and obviously the solution is to break that huge file into multiple

unfortunately pc will never get fast ram 😔 time to buy an epyc cpu

[keen sorrel]

Intellisense just happens to be a very RAM performance sensitive workload where M2's unified memory really gets to shine

[peak acorn]

Its just fact of the matter m2 ultra gets 12 channels of ddr5 (or is it 4 idk) where you can only get that speed on epyc

[keen sorrel]

EPYC doesn't officially support 6400MT/s DDR5 and the M2 ultra has 16 channels of that. Apple silicon is pretty crazy

[peak acorn]

🤡

yeah 16 mb. insane

[modest crystal]

i tried installing pip 2 times it still isint recognized as a command pls help

[modest crystal]

Yes I forgot to add it to path that was the problem

here is the full code:

    return 0;
    if (Milk < minMilk || Flour < minFlour || Egg < minEgg || Butter < minButter || Salt < minSalt){
    cout ;"no blin today";
    return(main;);int());
    }
}```

[cloud knot]

not sure about others, but that whole return statement makes no sense. you are returning main (what is main here? the entry point function) from main and whatever is behind it ?

you return a number; and everything else starting with ( and ending with ) after that return is syntactical nonsense (imo)

you literally just return 1; (or any other valid int) there, not return (main;);int());

also the whoile last section is unreachable code

the first return 0; literally stops the execution, so the if and anything after is not executed

[keen sorrel]

This was already explained the other day, not sure why they didn't follow the advice

[cloud knot]

in my experience with push notifcations with firebase - make sure the notification file in available as resource, you seem to send "notification.wav" but they seem to send path starting with ./ in their examples - maybe that is where the sound is broken ? For vibration, have yous et vibrationPattern ?

[cloud knot]

also do you do that build type and have that plugin ?

[haughty oyster]

yeah, I did set a vibration pattern (it's in the original message) and have these lines in app.json

Also, I'm trying to make it on-device only, it doesn't need to connect to the internet, it shouldn't actually since it's just a small tool

this is correct, right? I did build it with EAS and tested the APK on my phone but it didn't work

[cloud knot]

i haven't done expo, so i can't help you with their specific functionality, i was talking in general from Android notifications experience

whats your guys thoughts on this question for my assignment
Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.

public class FunWithCharacters {

   public String checkCharacter(String word, int index) {
      
   
   public static void main(String[] args) {
      
      FunWithCharacters labObject = new FunWithCharacters();
      String word = "happy birthday"; // Set string
      int index = 2; // Set specified index to 2
      System.out.println(labObject.checkCharacter(word, index));
      
      index = 5; // Set specified index to 5
      System.out.println(labObject.checkCharacter(word, index));
      
      word = "happy birthday 2 you"; 
      index = 15; // Set specified index to 15
      System.out.println(labObject.checkCharacter(word, index));
      
      word = "happy birthday!"; 
      index = 14; // Set specified index to 14
      System.out.println(labObject.checkCharacter(word, index));
   }
}

is what I have so far, the only thing written by me is the public String

[silk eagle]

the entirety of my thoughts are: weird wording on what its asking u to return (unless there was some markdown where the question was presented), my first instinct is that it wants you to return a string like "letter" or "digit" but that's not immediately obvious just vaguely implied

but also you can do it we all believe in you

https://www.scrapehero.com/open-source-web-scraping-frameworks-and-tools/ I would lean towards apache nutch if you don't need the GUI for anything and can get it all done through http requests and parsing pages/responses. If need a GUI for some reason would look more towards puppeteer or selenium based stuff like cypress (used for integration and e2e testing but is a general browser automation tool) @modest crystal

With regard to stock prediction it is a thing that high speed trading bots programmed by physicists have basically "won" but there may be some "space" for employing llms or other AI systems to analyze trends and whatnot and help to make longer term choices (as is most llms pretty bad at the long term planning and "true understanding" of dynamics in the world and spatial reasoning and whatnot but lots of room for training specialized ais for now still)

Also somewhat funny all the crypto hype over like the last decade and people probably would have been better off just dumping the money into Nvidia stock instead of buying up cards and/or crypto for the most part

Generally speaking the "problem" with scraping the public web (legal details aside) is typically lots of garbage info copy pasted between lots of servers and higher quality data is usually gonna be behind paywall of some sort and usually with throttling and policy that stops you from taking the data and running (or at least let's them chase you)

[modest crystal]

good luck getting your hands on a hft

[soft fern]

Yeah wasn't really sayin you should do that just sayin it's one of those places computing and statistical analysis and whatnot has been applied a bunch already and hard space to find a niche I think (not financial advice but personally just keep basically majority of stuff in "safeish" slow growth mutual funds and mess around with mess around money in stonks and other things)

[modest crystal]

not really planning to use this bot to trade more than like 1k just kinda like a project

[soft fern]

All good, you see Michael Reeves goldfish investment thing? Pretty hilarious

[modest crystal]

yea its somehow better than some investment bankers lol

[modest crystal]

most of these i have tried (the python ones) but they never seem to fetch the correct data

im tryna get the revenue and profit stats from yahoo finance

https://finance.yahoo.com/quote/MSFT/financials/?p=MSFT

but it is not fetching anything

[soft fern]

Yeah a lot of those sites have like paid API access too so do what they can to block out the scrapers, if you put in "enough effort" can usually work around things but some sites put in more or less effort to try and "protect" their data ultimately anything sent to your client and decrypted is readable though

Network tab in chrome and save as har and can parse through whatever you've been browsing while the network panel open.

[modest crystal]

i tried selenium too but it just doesnt grab anything it just comes as blank

[soft fern]

Lots of little make a http request and process the response are written in python since the string processing/parsing is pretty simple and you don't usually need like multi threading or other stuff to just batch process text

Yeah selenium is made as a testing tool so it isn't like geared towards scraping but can be used to generically interact with a browser

Yah that's one option for sure

You might want to just see what pricing is like for the different apis if they have a dev console (Google basically will give you anything for a price and a lot of free usage for sake of development)

[modest crystal]

i dont want to pay tho thats why im just tryna scrape

[soft fern]

Right but I'm saying you should see what you can get "free tier" and/or what the cost is since time is money

[modest crystal]

ok

where could i get the pricing details for like yahoo finance

[soft fern]

Google it 😉 hehe but really I dunno off hand

[silk eagle]

try making the same request without running headlessly and see where its getting caught up

[modest crystal]

alr

[modest crystal]

how do i do that

my current code

[soft fern]

I know like Google maps gives you a good amount of "free tier" stuff but they make you get an API key at least to track requests coming from your services and to throttle things eventually or make you pay but takes a while to hit those limits

[silk eagle]

well thats requests not selenium

[modest crystal]

i have two versions one with requests and one with selenuim wait

shit i deleted the selenuim one

[silk eagle]

chances are just using selenium will magically fix any parsing you do because the data is loaded dynamically and selenium will actually run the javascript on pages required to load that data.

[modest crystal]

ok let me just ask gpt to write me a selenuim script lol

@pep\

@silk eagle it just throws a gaint wall of errors at me

[cloud knot]

puppeteer is always a choice, as it technically runs a real browser behind it, but you might have hard time getting the data out of let's say charts

for example live updates clearly come through a binary data from
wss://streamer.finance.yahoo.com/ 😄

[modest crystal]

most of the stock website use charts tho

[cloud knot]

what i meant that if you can't get the data from network requests and you need to interpret already processed data from charts, good luck

if you can reverse engineer how the data received via web socket is processed, it is much more usable

[modest crystal]

good luck to me i guess

[modest crystal]

what does it do

[cloud knot]

if i understand it correctly, the basic idea is that you connect to wss://streamer.finance.yahoo.com/, send a {"subscribe":["ticker1","ticker2"]} message to server and you are then receiving binary data.
this.connection.addEventListener("message", this.handleWebSocketUpdate))

And then message received from backend is sent in to that block of code above. What exactly that code does is a good question. Atob does base64 decoding, so the first few lines creates an instance of quotefeeder object from that binary data, and then the data is processed. now what is the quotefeeder ? good question

[cloud knot]

https://stackoverflow.com/questions/58330057/python-web-socket-interpretingreading-data -> https://github.com/yahoofinancelive/yliveticker

someone made a python implementation of it, use convert it to whatever platform you want to use it in

[modest crystal]

ok thanks

[cloud knot]

https://stackoverflow.com/questions/59321908/decode-websocket-received-data/59382147#59382147 more info

[modest crystal]

yliveticker is good but yfinance is for historical data, which is what i need

[cloud knot]

ok, so you want it for the table shown on the page ?

[modest crystal]

i got it to work

[cloud knot]

recommend rate limiting yourself tho, otherwise they might put your IP on block list

[modest crystal]

i think yfinance is just a databast

but how would i do that

[cloud knot]

"rate limiting" - not requesting everything in rapid fire succession, but give some pauses between requests

i mean if you are interested in 1000 tickers - you don't send 1000 requests right one after another, but add let's say a 1 second pause between each call

[modest crystal]

alright

[cloud knot]

yes, it will take 15 minutes to download stuff like that, but server might give you a pass because you do reasonable amount of requests, not all at once.

[modest crystal]

ok i set it to 2 seconds

[cloud knot]

for example when Yahoo had YQL, they had a 1000 call/day limit for unathorized requests. Or there are for example this https://developer.yahooinc.com/dsp/api/docs/traffic/info/rate-limits.html, where that part of yahoo allows 60 GET requests per minute - so exactly 1 request per second, but only 8000 requests per day

so it depends on the service, but it is good to not overwhelm the target when you do scraping, so you don't put a target on yourself

[modest crystal]

ok

there is also a library called yahooquery which does exactly that if anyone wants

[torn quiver]

[stone mirage]

Hey guys I need advice.
I want to build a simple application that has a ui, a database and can plot the data.
I know a bit of sql and also python and matplotlib.
I already did a small and easy project where I had to get data from an excel table and plot it, and I used python with matplotlib and tkinter, and I did not really like tkinter, but i don't know how i would create the ui without it.
I know I am really picky, in fact i also hate VB (at school we used MAUI and i hated it).
Also i'd prefer to not have to use JS as I'd like to wait to start learning at school in september.
If you have any ideas please share.

tldr: need a way to create an application with database, ui and data visualization, preferably without js or .net
p.s.: I do not speak english as a first language, and excuse me for any technical error

[chrome saffron]

Looks good to me

[nocturne galleon]

Since WHEN did typing HTML in vscode got so easy??????

[soft fern]

pretty sure since vs-code existed, it's always really been geared towards web dev, some things still require extensions to get completion or compilation for but has always been pretty web friendly/focused out of the box

maybe you're confusing it with visual studio or something,visual studio is more geared towards C# or desktop application development out of the box, sometimes used in combination with Unreal engine or other things

[soft fern]

tkinter is definitely a popular option for UI development in python another alternative for desktop UIs you might want to look at is PyQt. UI libraries in general are not that great to work with hence a lot of things just using a web based UI (wide compatibility and lots of folks who know HTML/JS well enough to hack things together relatively quickly, CSS is a nightmare but it gets the job done). If you wanted to make a web API in python and have a web UI you could use FastAPI, SQLAlchemy for ORM so you don't need to write much SQL by hand just dealing with objects in python and mapping them to tables, Alembic is good for migrations if you want to go the extra mile and make it more "real world". It is also typical to architect things in a way that you have a REST API with JSON requests/response bodies and then build your client UI as a separate application that consumes the API but for classwork with limited time (or POCs) is typical to skip on things and take short cuts to get things done.

Also, if you wanted to have the python layer just like output preprocessed web pages might be worth taking a look at Django or Flask, both allow for making web APIs, Django includes ORM as well so would not need SQLAlchemy if using that, Flask is a bit more "lightweight" than Django but still lets you handle setting up "route handlers" easily and has some html templating I believe.

I want to get news data for a certain company for the last year. NewsAPI only allows you to go back a month. Any help?

Or perhaps just grab market sentiment

[drowsy elbow]

Their C# example code shows that you can set a "From" property in your request. Have you tried that?

@modest crystal

I guess you need to pay if you want articles older than 1 month

[drowsy elbow]

Perhaps if that specific company publishes it's own news, it could be scraped and then be kept updated via an RSS feed.

[modest crystal]

I should have specified this before, but i need it for the top 500 companies

May I ask an absurd question of curiosity,

What if we made a system/program to use the graphics card of a thunderbolt connected device

In theory something like that would be doable on a phone with adb and BlueStacks

But on the scale of 2 windows machines, i should expect that there would be more room for possibility given the connection strength and so forth

How can I make it so that Docker doesn't keep my GPU awake on my laptop? I've tried setting the desktop dashboard to only use integrated graphics but that didn't help. Going to the file path of WSL through Task Manager doesn't even open anything

[spring compass]

If I recall correctly there is a setting in docker desktop that will basically put containers to sleep if they're not in use. You can try that. If it doesn't help, you may actually need to stop the container that is using that GPU device. If it's an Nvidia card, I believe there is also an option in the Nvidia setting somewhere to disable staying awake when the GPUs in use. Don't quote me on that but I swear I saw one in there.

thermally modeled mosfets in ltspice using many cores. 35min to get 306us, avg 146ns/s. I wonder if only more cores will help or if 3d v-cache affects performance too

[acoustic pine]

If the workload involves moving a lot of data between ram and cpu yes

Though I'm unaware of anything that benefits from cache outside of games

[keen sorrel]

That's not quite what extra cache is for. It's specifically for repeatedly accessed data, typically code. Being able to keep more code in caches is great for games since they're usually big pieces of software. Moving lots of data is what bandwidth and raw processing performance is for. I have no knowledge of ltspice's implementation, so I don't know whether there's a lot of code or repetitive data accesses in the algorithms it uses.

I compiled a version of my application for 64bit Windows 10, 32bit Windows Vista, and 64bit Linux.

How would you distribute each version? Should I have all 3 in the same .zip file, have different downloads for Windows and Linux versions, or have a separate download for each of the 3 versions

[chrome saffron]

Some bundle, some separate by OS, some separate all of it. It really just boils to what's more convenient for you.

[lament gulch]

Ya

[cloud knot]

on github etc they usually just give out source as one zip, then exe/whatever for each platform separately

Hey guys! I'm new to coding and just made a Discord bot called Records. Would anyone be open to testing it?

It's supposed to stores memories in Discord by letting people save messages others have sent, as well as view anyone's saved messages. people can also delete their own saved messages.

I can send the invite link for the bot if anyone's interested!

[soft fern]

Yeah on releases page typically different files for different platforms targets so can just download what you need or get the src and build from readme if a package for your target OS doesn't exist or need to make changes and rebuild/bundle, they could just grab src from git though assuming GitHub or gitlab or the like being used to host the packages

Could do the "Uber zip" with all platform versions included but just making people download extra junk and copies of things they'll never use too

[soft fern]

Literally everything benefits from caching, caching just means keeping copies of data close to where it will be used, prefetch loads nearby memory into caches to basically have the data at the ready so there is no need to request it from ram or request it from disk if it's already in a CPU cache, if the disk has a cache and need to load something that happens to be a cache hit (something in there) then will use that over accessing the disk, cache is just a spot to dump copies of things along the way so you don't need to go back to the source

Redis is an "in memory"/ram cache system to basically keep disc contents loaded and ready to reduce access time, the l2arc in zfs is a similar disk to ram type system, caches exist at multiple levels for DNS hence the "it's always DNS" problems, caches in browser, it's caches all the way down 🐢

[left ivy]

fun facted do you know one of the main reason why cod an games like it are so storage heavy its becuse insted of not downloading all the weapon an skin shit thats all animated in bits an pieces they downloa it all in one go even if you dont have it unlocked in game its there so when you do warzone rememeber this when there is liek 100 of yall there is so much crap on the back end that its not even funny why you have to run a high end pc for high fps there is some other technical aspects to this but the mojority of games run like this
side note we dont need to have loading sreans any mroe the loading screan is jsut a error check and ids check now besides slower inter net checks
a few gaems i do play run a thing that is used when you unlock the skin the loading animation or transfer animation is the game downloading the skin that you need/ unlocked

[noble plover]

there's definitely certain kinds of workloads that benefit more from extra l3 cache than others though

productivity apps generally handle too much data for it to make much of a difference while games have certain bits of code, data and assets that are very frequently accessed, which is why 3d v-cache benefits them more than productivity apps

(usually)
because of course with that said there are productivity apps that handle the extra cache well

[soft fern]

Sure it varies how often you're going to get cache hits for any given task but it's not "just good for games" it is good for processes that can make use of the caches and end up with hits more than misses

[keen sorrel]

https://www.amd.com/en/products/processors/server/epyc/4th-generation-9004-and-8004-series.html

3D v-cache is definitely not just for games lol. Nobody is gaming on these.

Unless they're used for game servers

Does anyone if it's possible to auto-archive files in specific folders to my NAS when they aren't accessed for x days, while keeping them accessable in a similar way Onedrive does?

Hey there. Is there a way to readout every media stream running with codec etc os-wide?

[cloud knot]

blame developers/companies who abuse everything the platforms provide. Unfortunately all these things have to go, because people will abuse it for fingerprinting or spamming/annoying users

[woeful rapids]

yes

[soft fern]

What OS? But probably not, detecting if a program happens to load up some codec at runtime and uses it to decode or encode some stream of data isn't really like an OS level responsibility. You could probably monitor what processes are using the hardware decoding capabilities but not much else about what they are doing with the data inside that process... What's the actual goal and target system though?

it coming along nice, In one of the imgs upload you expose your OpenAI key please hide it for your safety

[graceful drift]

@blissful geyser LOL not mines

idk who uploaded that ill check it out

[blissful geyser]

upload speed is not bad, What are youtr target file types

[graceful drift]

yeah i got none api keys

[blissful geyser]

ok

[graceful drift]

uhh let me check

i forgot to add a file restriction i was working on file size limit

[blissful geyser]

yee i saw it allowed me to up load a pdf file:

[graceful drift]

see idk what to do i create a docker file of it and host it on my server and to expose it i use cloudflare tunnels its slow tho idk why

{'png', 'jpg', 'svg', 'gif', 'mp4', 'webp', 'ogg', 'webm', 'bmp'} is this good?

that is all html allows to show in videos and image format

@blissful geyser

[blissful geyser]

you dont use DevOps

[graceful drift]

i pushed the fix for the file extention thats allowed

[graceful drift]

no.

how should i

i need to fix it to not make multiple of the same files be uploaded

[blissful geyser]

when you pushed first did it work, where did you push it

[graceful drift]

i made my own python system that auto makes the docker image and redeploys with the same data from before like if user uploads images the images are not deleted only the code does

i use a ubuntu server in my house running docker and portainer and to expose i use cloudflare tunnels

and my python code connects to docker to make it happen

im still learning lol

i know there is a better way to do that

[blissful geyser]

well you have to figure out that on own, debug

[blissful geyser]

me too

[graceful drift]

im gonna have to delete all user media that was uploaded people are uploading some not so nice things

[blissful geyser]

i am not a python expert , but in java and Golang we Threads to handle concurrent user request's

[graceful drift]

this is what my folder for the code looks like

its simple but i want to make it in another lang

i made a big mistake before if you want to know about it i can tell you

and my teacher looked at it when i did not know people did that with it

its was a V1

we got 2 more months for the project

[blissful geyser]

what lang

do you have on github

[graceful drift]

idk mostly python i uploaded what i made when im learning

i think i had some js on their

i had to add hcatcha to my contact form bc i would get stuff from seo company bots

i did not pick recatcha bc its only 100,000 request a month on their so i pick hcatcha bc they give 1 million a month

i was dumb couple months ago when i started too i have my contact form data gettign saved to a TXT file lol now i got it getting emailed to me

[blissful geyser]

we live we learn

so all the logic is in main.py

[graceful drift]

i got it like this now

its only 180 lines

[blissful geyser]

do you have it on gitHub

[graceful drift]

i can upload the prod one now

[blissful geyser]

ok can you send me a link

[graceful drift]

ok give me a sec

@blissful geyser

i also got a web chat i made but its broken

@blissful geyser https://chat.rapter.pro the manage profile is broken it does not update the db when users change something on their profile

[blissful geyser]

where do you store data

[blissful geyser]

good practice is important, you need to separate the logic from the handlers/routes

[graceful drift]

i store media in a folder it is created once the code runs

its named uploads

app.config['UPLOAD_FOLDER'] = os.path.join(os.path.dirname(__file__), 'uploads')

should i seperate them using diff python files or smt diff

this looks fine for one file

[blissful geyser]

use SQlite, storing it on a folder is complex(Profile Details), if you want to store images use a BLOB

[graceful drift]

i store files thats uploaded in the uploads folder which connects to a docker volume so it stores their

and ip address and other cookie data are gonna go in a mysql db that i run once i get it set up

[blissful geyser]

wait the app runs on docker

[graceful drift]

thats what the docker file is for

i have a stack on docker with a db volumes and every thing thats needed

im gonna have to push it to docker hub in a image for my teacher

[blissful geyser]

ohhh , i was confused

[cloud knot]

1. if it is a fork/can be forked (always private repo can't be forked)
