pip freeze > requirements.txt

but uhhh

have you used a virtual environment for your project?

[sick marsh]

yes, I got that figured out this morning

doesn't seem to actually write to a file, is it necessary to create a blank requirements.txt file for it to write to? I assumed it would just create it

oh it actually did save to a file on the drive, just double checked, thanks!

just expected to see it in the file explorer in VS Code, used to that in Windows Pycharm

[nimble panther]

cool 👍

[sick marsh]

thanks Vivek 🙂

[nimble panther]

why can't my spyder detect modules installed through conda?

(on 5.10.16, manjaro)

it works for some but not for others

for example i've installed discord.py through conda-forge and i can import it

wiil u be able to help me with git?

[sudden mirage]

I don't mean to be rude, but these are things that can be easily googled. Here is a tutorial to send you on your way https://git-scm.com/docs/gittutorial

[real swan]

yes i have been referring and have done lot of google work

but i did not understand few things

@sudden mirage how do i run a program from command line?
in order to get aquainted with git each one of us pushed pow of 2, power of 3 ... 7. Now we want all these to a main program so that when the user is prompted for which power he wants, the result will be computed by corresponding function. So my question is how do we combine all these files into a single program and execute it (the main function is another push)

i spent almost a week searching these, yet failed to find a solution.
Also thank you for patiently answering my queries
any further help in this would be welcomed
thanks in advance @sudden mirage

anyone who can help me out with this are also welcome

[median needle]

You can run a python program from the command line like this:

python myprogram.py
or, depending on your distribution
python3 myprogram.py

[real swan]

sorry u got me wrong

im asking smthg related to git

i have given a description above

@median needle are u familiar with git?

[warped nimbus]

What does git have to do with running programs from a command line?

Git isn't design to run programs. It's designed to do version control of files.

[real swan]

im using git from command line

if u have different functions uploaded in git (which are part of a main program) then how do u run them by clubbing alltogetherin a single program?

[warped nimbus]

You need to pull them from the remote repository with e.g. the git pull command.

Then those files will show up on your local machine.

And you'll be able to do whatever you want with those files, like execute them.

[real swan]

oh !!!

then i think ive complete;y gotten the ,idea of git wrong

clarif my understanding that i have got from ur explanation rn

@warped nimbus

is it like each day u work on a same project byimprovising ur code with neccessarycommit msgs indicating ur changes and then there will be one final program for us to run ultimately

right?

[warped nimbus]

Basically yes.

You can work and change existing files, add new files, delete files. Then you can commit and push those changes, typically to a remote repository that is on the internet like GitHub, GitLab, etc.

And at any point, anyone can pull the files from e.g. GitHub and run the code on their machine.

[real swan]

y do we add new files

[warped nimbus]

Because complicated programs are spread across more than a single file.

[real swan]

pls do bear with me @warped nimbus i liked the way u r explaining

[warped nimbus]

For organisational purposes among other things. It's difficult to work with really long files.

[real swan]

so how to we link one file into another then

[warped nimbus]

And you may have other files like images, data, etc. that your program needs.

[real swan]

exactly

[warped nimbus]

Well, you don't need to "link" them as far as git is concerned. They'll just all be part of a single repository. You cannot pull individual files with git - you always pull the full repository.

[real swan]

thenby only specyfying the name of the file they ll be directly accessed into a program>

when they are part of same repo.

my q is related to images thingy

[warped nimbus]

Git preserves the directory structure you have locally. So if you have a code.py inside the source directory, it will be the same on GitHub too, for example. When you pull the repository, git will create a source directory and put code.py inside of it.

So if you have another file, it can reliably do from source import code.

[real swan]

that happens implicitly?

from source import code thing

[warped nimbus]

No, that's code that you write if you want to use another python file. That's just a basic Python concept; it's not related specifically to git.

[real swan]

yes ive done that while working with python files on system but not with git so hence i had got that doubt

hope im not disturbing u

i have few more qs

cos i dont know if its day or night there

[warped nimbus]

Yeah it's night here and I will indeed be leaving soon. Just ask anyway. If I can't answer then someone else might. If you have questions about git, #tools-and-devops is a better channel since your questions so far haven't been specific to unix.

[real swan]

jus consider this small example - i have a git repo ,with each file with different functions and uploaded em.
now i have another file in same repo that has a main function and that has a code related to all of the func present in above files . now if i run the main fun file code will it run properly?

or shud i include from source import file1 file2 ....

in the main func program

[warped nimbus]

If you rely on code defined in other files then your main file will need to import the other files. If you want to learn more about it look at these articles https://realpython.com/lessons/import-statement/ https://realpython.com/python-import/ it's getting off-topic for the unix channel.

[real swan]

oh ok @warped nimbus thanks for ur time and u have really helped me a lot
thanks a ton

[warped nimbus]

You're welcome

[real swan]

Thanks buddy got it with ur solution, im gonaa delete the post from #tools-and-devops group

how to run some python code if active window changes in linux?

i am looking for solution that do not need infinite loop for checking active window to determine whether active window is changed

[main olive]

my first thought would be to use an event listener

listening for the file change

some system/gtk related file that would contain information about which window is active

but i couldnt find online

any information

on what that file is

https://superuser.com/questions/382616/detecting-currently-active-window/615946

i could only find how to retrieve the current active window via higher level tools like the one above

[red peak]

import psutil

pid = subprocess.check_output(["xdotool", "getactivewindow", "getwindowpid"]).decode("utf-8").strip()
prevpid=pid
print(pid)
while(True):
    pid = subprocess.check_output(["xdotool", "getactivewindow", "getwindowpid"]).decode("utf-8").strip()
    if prevpid!=pid:
        process=psutil.Process(int(pid))
        processName=process.name()
        print("Current Active Process is "+processName)
        prevpid=pid```

i have tried this code, it works but i think it is super inefficient

how can i eliminate that while loop?

[heady heath]

guys how to create a new folder in desktop by using linux terminal

any idea or is it impossible?

[barren temple]

mkdir command makes a new folder.

[real swan]

i need to do that in desktop

which is not possible with above cmd'

[real swan]

??????????///

[main olive]

mkdir -p ~/Desktop/MyNewFolder/

[covert belfry]

should i come back to linux lads? i had archlinux, went fine for me but idk i think i liked linux more. the reason i moved is because i have got a 2nd monitor connected to my laptop (laptop has an intel gpu and nvidia gpu) and on archlinux it doesnt wanna work. would it auto work on gnome or an other de? i used i3-gaps before so im not sure

[real swan]

did not work either @main olive

[thick drift]

How long ago was this? Are you interested in a full DE or a window manager?

[covert belfry]

i dont know, i liked i3-gaps a lot

[real swan]

how can we cd to desktop @main olive

[covert belfry]

cd ~/Desktop

[real swan]

OMG thank you so much

i had been spending months to get this

[covert belfry]

😐

[real swan]

why doesnt the ususl cd work and what does this mean

[covert belfry]

~ is the home dir

[real swan]

yeaah i googled jus to find no answer

[covert belfry]

and Desktop is located in the home dir

[thick drift]

I would have to read through the i3 docs again. Also look at sway wm if you aren’t using an nvidia hour

[covert belfry]

cd ~/Desktop && mkdir "New Folder"

@real swan

[real swan]

where do u find home in desktop is it ur name thingy?

[thick drift]

Or gpu not ‘hour’

[real swan]

yea got it and thanks a ton

[covert belfry]

well i got 2 gpus as mentioned, one integrated and one external

[real swan]

~ this means home dir?

@covert belfry

now im unabl to cd into folders present in desktop @covert belfry why is that so

[covert belfry]

stop trolling

[real swan]

?

trolling?

[covert belfry]

when ur in desktop

[real swan]

im newbie

[covert belfry]

do cd folder

[real swan]

yea i did that

didnt work

no such file or dir is the msg

[thick drift]

Sorry, forgot that part already. Nvidia is working on a wayland driver, but eta is this summer. My advice is to try manjaro on a live usb. If you can get monitors working, then switch. If you think it’s close and will do some ts, switch! If it’s a hassle, stay where you are.

[covert belfry]

mkay

[covert belfry]

do ls

and see if u have that folder there

[real swan]

yea i did

nd found the files

[covert belfry]

what distro do you enjoy?

[real swan]

i closed and opened n now it works

thank u

[thick drift]

Fedora

[covert belfry]

im thinking about manjaro

[real swan]

aftr creating the folder im not able to find it on my desktop

[real swan]

can we find it or is it that way only

anyone to help me here?

[sudden mirage]

Just type the name of the binary

[covert belfry]

./name.sh

[sudden mirage]

And to make a folder do mkdir folder

[real swan]

i did that but im not able to find the folder in my desktop screen

[covert belfry]

what de

?

what desktop environment

[real swan]

i use windows

and debian terminal

[covert belfry]

u mean wsl2?

[sudden mirage]

You mean WSL

[real swan]

yesss

[sudden mirage]

Then it won’t work

[real swan]

y

[covert belfry]

lol

[sudden mirage]

WSL is not integrated into windows

[real swan]

that was rude

[real swan]

oh k

[sudden mirage]

If you want Linux commands to work as they are meant to

[real swan]

so no other alternative

[sudden mirage]

Use real Linux

“Real”

[real swan]

🙁

[sudden mirage]

But yeah

Use real Linux for the best experience

[covert belfry]

u can cd to ur home dir

cd /mnt/c/Users/

and then into ur user

desktop

[real swan]

but wts the use of getting into desktop

[covert belfry]

do this @real swan

[sudden mirage]

That too

[covert belfry]

ok gtg

bye

[real swan]

why?

[sudden mirage]

But WSL is not the best Linux experience if you want the real thing

[real swan]

ok

[covert belfry]

its not supposed to be

[sudden mirage]

Yeah ik

It’s supposed to be a good drop in experience

Which in all honesty it is

[real swan]

then wt are those folders which i can find present in desktop which is shown in terminal

[sudden mirage]

Ok

WSL is basically a little VM to put it simply

So the command line is pretty much the only way you can access it

I’m pretty sure you can do explorer.exe to pull up the file manager

[real swan]

i dont know all these things

[real swan]

got u here

[sudden mirage]

I just told you what you can do

Wdym you don’t know it

[real swan]

what is explorer.exe?

[sudden mirage]

Just type it in

[real swan]

im always scared that i wud end up messing up with my system

[sudden mirage]

It’s WSL

The worst thing that could happen is you break WSL

And if you’re so scared then at least check what the commands do

[real swan]

we actually are doing a small hobby project and there are nobody to help with technical issues

so im refraining from doing such things

i dont even know how to dual boot my system

[sudden mirage]

https://ubuntu.com/tutorials/command-line-for-beginners#1-overview

[sudden mirage]

Just watch a YouTube video

I did it

Pretty easy tbh

[real swan]

i have heard this from many

but one day ill ping u for this if u mind

[sudden mirage]

To dual boot?

[real swan]

im litrally scared of backing up

[real swan]

yes

🙁

[sudden mirage]

Fine...

[real swan]

will u accept my friend request cos im not able to pin u also. orelse u want me to type in here?

there are lot of servers right in here

[sudden mirage]

Just type it in here

[real swan]

okie

thank you so much

i never found people on discord who understood and responds to me this way

as soon as i say i dont know to dualboot they pass on ironic comments here

[sudden mirage]

That might be because you can easily learn it on YouTube

But fair enough

[real swan]

telling wrt my situation or u telling they are not wrong from their point of view?

whatever it might be the way you communicate is really good ...

also @sudden mirage have you ever used git?

i have few qs on that too

[sudden mirage]

Yes I use git

[real swan]

so wn we do a project what are we supposed to push and how do we build em

i have some idea about it

but building a project is making me think something difficult

cos ive seen ppl uploading individual files but how do they run the entire project?

[sudden mirage]

Where are you pushing the project to

[real swan]

they dont even specify from ___ import * or something like that

[real swan]

a repo

[sudden mirage]

Python has nothing to do with git

[sudden mirage]

On GitHub?

[real swan]

im basically doing a python project so specified that way

gitlab

[sudden mirage]

Like I said before, python and git are mutually exclusive

What you do with python won’t change what git can and can’t do

[real swan]

jsu a moment ill post a qs which i posted on pther server

i had posted it here only

in order to get aquainted with git each one of us pushed pow of 2, power of 3 ... 7. Now we want all these to a main program so that when the user is prompted for which power he wants, the result will be computed by corresponding function. So my question is how do we combine all these files into a single program and execute it (the main function is another push)

and got an idea but i dont feel that was right

[sudden mirage]

That makes absolutely 0 sense

You can’t push individual function

You can only push files and directory

And all you have to do is combine functions in one file

And I don’t think this is the right place for this

Try one of the help channels

[real swan]

are u availab;e there too?

[sudden mirage]

Frankly, I’ve got things to do and places to be, so no, I don’t think I will be available there

[real swan]

😐 yes i understand sorry if i had troubled you

[sudden mirage]

It’s fine, don’t worry about it

[real swan]

bye

[main olive]

you cant

re-running the same process like xdotool is your only option like i said in my original answer

[coarse shadow]

Guys, can I get a quick reminder on syntax?, it's driving me nuts

[summer trail]

you're looking for sudo bash -c "some shell commands"

but also, that's a roundabout way of doing it in the first place

[coarse shadow]

Yyep. Knew something was amiss

Tried to do both instructions separately hut it just wouldn't

[summer trail]

you can just do sudo ./pyenv/pingenv/bin/python pingaso.py instead

I resumed my VM today and discovered that sudo is rejecting my user password. I switched to root with su and used passwd to update my user's password, but sudo is still saying my password is incorrect. What's going on?

Maybe I just need to reboot, but I'm concerned that if I do that I may get locked out of my user.

Okay rebooting actually fixed it. Really strange.

I didn't even actually change my password I just set it to presumably what I had all along.

what are you trying to do? Writing to files under/sys requires a great deal of caution., and many of them the kernel will not allow to be written by any user.

[stiff tangle]

I'm trying to install an application that lets me control the fan speed

[olive bison]

ok, that is a valid reason to manipulate /sys, but perhaps the app you are trying to use is not doing a very good job of it... what happens if you run cat /sys/kernel/debug/ec/ec0/io ?

[stiff tangle]

It shows me one file with root prefixed

[olive bison]

did you get this program from pypi?

[stiff tangle]

I got it from a public github repo

[olive bison]

imo the fact that it's throwing unhandled exceptions while trying to manipulate files under /sys means it might be worth rethinking if this is the best software to do what you are trying to do

I can control the speed of my fans by just manually writing files under /sys if I feel the need, I'd feel much more comfortable using a small script i wrote myself instead of something from guthub that has already proven that it doesn't work right

yep, but windows guys wont care

from my experience

nah, so ofc it's meant to work universilly, but there are ofc ways to break this

for example importing certain packages that rely on a specific OS

and if nothing helps

just dockerize it

[main olive]

you will have to elaborate on the "dockerize" part for him

[opaque ginkgo]

most python programs should work cross platform

as long as you don't rely on os-specific features like the filesystem hierarchy

[rugged swift]

Consider to try with -e, so echo -e $command_to_run

[warped nimbus]

I suggest you use printf instead. Its behaviour is easier to understand.

I tend to only use echo with string literals.

i.e. strings without any expansions etc.

ok thank you very much guys 🤝

[main olive]

nop, still the same issue. Cronetab is doing it's job well, but when I run my main script (ubuntu@ubuntu:$ python3 main.py cronetab stops the process

[harsh owl]

what is the cronjob you have? does it have the fully qualified path to python and the script you want to run? you can capture output and stderr into a file to see what is going on

you can even run the cronjob in a screen session you can resume later to see what executed

[main olive]

so the cronjob looks like this: * * * * * cd /DiscordBot && /usr/bin/python3 /DiscordBot/update_income.py

[harsh owl]

that looks reasonable. if i was you i would look at capturing stdout/stderr, add some logging statements etc.

Then install it through your package manager

ex:apt install python3-tk on debian/ubuntu

@sharp hedge tk on pypi is some random other package

@vivid sequoia ^ btw

[ripe musk]

Anyone bothered by search being broken in pip?

The only package manager without search functionality...

[opaque ginkgo]

yeah pip is honestly kinda bad

compared to other package managers

[opaque ginkgo]

downsides to having no verification on packages

[lavish hemlock]

I miss old internet

[kindred basin]

The main thing I hate about pip is that there's no upgrade functionality.

Like, yeah, you can manually upgrade a package with pip install --upgrade, but who's going to go through every single package they have installed and try to upgrade it?

[sharp hedge]

yes I'm using ubuntu

that should work then

thanks

I deployed a text-based game utilizing websockets to a server running Linux. This text-based game uses the sleep function for pausing before sending a JSON object containing text to the client. My development environment is Windows.

In Windows, the sleep function works properly and the server pauses accurately before sending the data to the client at the specified time.

However when in Linux, either in the development environment or during production, the client receives the websockets event data all at once as if the server didn't even pause, but the server IS pausing for the appropriate amount of time.

I dont know why the event signal is getting received all at once like that. Any help?

[lavish hemlock]

@kindred basin You can make an alias

alias pip="pip install --upgrade"

pip install module

there is also:

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

or

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U```

[summer trail]

What library are you using for the web sockets? That sounds as though something is being buffered, and a flush is needed before sleeping, perhaps.

[tender plinth]

Excuse me if not supposed to ask this here , but , I have a remote test service which is dumping an executable in the form of hex literals (something like - ELF\x10\x00\x30 , and I want to recieve this data and convert it to its ascii form so that I get the proper executable, does anyone know how this could be done using python?

[summer trail]

If you have control over the remote test service, it would make your life easier, and make the transfer faster, if you had it send the executable as base64 encoded text, rather than printable ASCII with embedded hex escapes.

[tender plinth]

i dont have control over the remote service

[summer trail]

That's unfortunate.

[tender plinth]

so is there a way to convert all that hex literal data into executable format?

[summer trail]

Wait... Does it return "ELF\\x10\\x00\\x30", or does it return b"ELF\x10\x00\30"?

If the latter, it's already binary data, and you just need to write it to a file:

with open("filename.ext", "wb") as f:
    f.write(data)

[tender plinth]

oh thanks alot!!

[opaque ginkgo]

that doesn't even work, also you probably shouldn't shadow pip like that

[lavish hemlock]

Works for me @opaque ginkgo

[opaque ginkgo]

wb pip show

or like literally every other pip command

now thats broken

[warm thistle]

I built the asgi function myself in django.

[warm thistle]

@summer trail where usually are the events being buffered? Is this in the WSGI/ASGI software (im using uvicorn/gunicorn) or somewhere after this?

[summer trail]

I'm not familiar with with websockets to be able to offer any specifics, I'm afraid

[warm thistle]

Thank you for this hint tho!

[autumn forum]

Yo, Does anyone know how I can make it so that when I'm in python on my bash terminal I can use the up arrow key just like in bash to do the previous command. PS, I'm using python as a calculator It's sooooooo usefull.

[dapper musk]

what it works by default

[harsh owl]

i think it depends on readline.. it works for me by default in linux as well

answer might be in here somewhere; https://stackoverflow.com/questions/6558765/how-do-you-see-the-entire-command-history-in-interactive-python/7008316

[dapper musk]

oh you must make

.python_history(betwen interpreter invocation it works by default in 1 session)

in your's home dir

Hey everyone. I'm looking for a nice monospace unicode-aware font to use in my terminal. I'm using Deja Vu Sans Mono at the moment with noto as a fallback but I can't see any of these unicode characters in my terminal: https://www.unicode.org/Public/security/8.0.0/confusables.txt

[sharp hedge]

Do most of you all use linux as your main OS?

I got tired of virtual machines

[warped nimbus]

Nope, but I want to. Keep finding excuses to put it off or I don't have time to migrate.

I'm putting up with a VM

[harsh owl]

ThunderboltSH: for the last 25 years.. ;)

[dapper musk]

for 2 years because programming on windows from my experience was nightmare.(lack of Package manager and this awful paths importing in this awful UI from windows 95)

[sharp hedge]

😅

[sharp hedge]

NOICE

yes

I set up dual boot

and I hardly boot into windows

[sharp hedge]

yes true file paths in windows are annoying

[harsh owl]

my beefiest box is actually generally a windows machine.. purely for gaming.. i try to keep the windows hassle to minimum but it manages to annoy me fairly often

[dapper musk]

yes sadly gaming on linux is awful especiali if your's hardware is lower end.
it is acctualy 1 reason that i have dualboot

[harsh owl]

yea i dip back into linux gaming on occasion, way better than it has ever been but still just not really comparable for any higher end game

[dapper musk]

yes but some developers are making native versions for example linux factorio version works beter than windows one + for some reason company of heroes 1 works beter in wine that on real windows lol

[warped nimbus]

There's technology being actively developed to allow sharing the GPU with a VM. It's still not mature enough unfortunately. Currently what people do for VMs is have a separate GPU for the host and the VM.

[dapper musk]

well if you have intel igpu i think you can use it for linux and linux desktops generaly(not GNOME) are light

[warped nimbus]

https://looking-glass.io/

Hopefully the technology will be there for a single GPU in the next decade 🙃

[dapper musk]

🙃

lol it is windows only

ah there is debian version

[warped nimbus]

As a guest, yes.

[dapper musk]

on their webiste i see only windows host binaries(maybe debian repo has one)

[warped nimbus]

Because the typical model of distribution for linux is via source and building locally

That's what package managers do

[dapper musk]

i know i pointed out to debian

sadly my PM do not see it

• .deb is for some reason not compatiblie with non debian based

[sharp hedge]

I feel linux is good for gaming as well. It's true that less games are supported. But we can use wine

[sharp hedge]

try Zorin OS

[dapper musk]

oh i dont think it can beat gentoo wine performance

xd

[slate knot]

does anyone know how to create a video device like /dev/video0? I want to stream a video across a network and into that device, so it can be used as a webcam

[steep wagon]

i am struggling to use sed to add suffix to each line of a document i am using sed 's/$/.mp4/g' filename

[summer trail]

I settled on Roboto Mono last time I went looking for a programming font

It appears to handle many of those confusables, at a quick glance.

[sharp hedge]

lemme give it a try

[sharp hedge]

which is better? Arch or Debian?

[limber ocean]

Debian is my opinion

[dapper musk]

arch imo debian repositories are preaty old i know abount debian unstable but still compiling anything is awful beacouse almost always source requires more modern packages than debian have.

[amber garnet]

Yep, it's big problem of Debian which I noticed

[sharp hedge]

alright

yes

Debian does not deem to be good

[dapper musk]

but it have 1 + it is super stable it eaven ran 1 year non stop on my rpi

[amber garnet]

I didn't say that!

Guys in my department have many Debian production servers and all are working fine

[dapper musk]

oh debian is great for servers

imo not so much for personal use

[sharp hedge]

yes I mean in my opinion

[sharp hedge]

I prefer distros derived from debian

[dapper musk]

oh i ment debian based for example distors as ubuntu and deepin are mailny GUI changes

cli is ~ exacly the same

[sharp hedge]

yes some minor changes like we are not added to sudo users for example in debain

which is kind of annoying

[unique thunder]

Thanks for the suggestion.

[autumn wolf]

I have a question. For me, uname -r returns 4.1.2-finnix how do I change that to generic?

[dapper musk]

it says your kernel relese

so in order to change it you must install new one

and you realy should 4.1.2 is preaty old

if you are concerned why you are geting 4.1.2-finix not 4.1.2-generic then it is distro specific

and mainly it is the same thing

[past sluice]

can someone help me regarding ansible

playbook

[dapper musk]

yes they are

software in debian repos is way older than in idk arch ones

[dapper musk]

eaven debian default kernel

is awfuly old

[main olive]

Hi

[amber garnet]

Hey

[main olive]

Sup

[opaque ginkgo]

not if you run testing 😛 (5.10.0-5)

[dapper musk]

it is sill old😛

[dapper musk]

i said that lol

imo arch is beter for personal use

and debian for servers

and this is just my opinon

[dapper musk]

was't cent os killed by redhat?

[dapper musk]

"we" are you in dev team?

[main olive]

I'm not 100% sure where this should go, but this is the closest channel to the topic I think, so recently I've learnt mmaps and how they are quite efficient. but is there's a time where you don't want to use it? like, can I just use mmaps all the time as opposed to normal .opens?

[dapper musk]

yes

but minor one

for example you on 32 bit systems you can directly addres up to 4GB of fille

and for example you cannot load fille from some potrafle device and then unplug

and mmu are faster but only on hardware that suports it

if hardware do not does so mmap ill be handled as normal open but it ill acess only small amount of data so well it will be inefficient

• it can have somme additonal error for example if 1 program is writing to file and 1 reading it but it should be handled by OS

oh then gl working on it

[main olive]

Hi

HElp me

[dapper musk]

in what?

[dapper musk]

why are you doing it in root directory?

if you realy need to

then type sudo before

but you realy shouldnt clone to root

[main olive]

So where to do?

[harsh owl]

type cd ~

and rerun command

also learn about homedir and permissions :P

[dapper musk]

and linux file structure

[main olive]

Ok I ran these

But having problem with this

[harsh owl]

what do you think the issue is based on the error message?

[main olive]

can't find that command somehow

[dapper musk]

did you instaled this?

[main olive]

createdb hive was

hive sync means yncronization I tinhs

think*

[dapper musk]

can you link this github page?

[main olive]

ok

https://gitlab.syncad.com/hive/hivemind

[dapper musk]

can you show output of python3 setup.py install --user

?

[dapper musk]

full

use >> or > to do so

at the end of the command to route output to file

[dapper musk]

yes i told her/him to change that

o nice command

XD

m1?

oh i wanted to buy m1 air

ah F

well apple pricing

witch model did you bought?

pro 16 inches

?

so you maxed it out

does it have problems with thermal throttling?

[dapper musk]

good to hear. maybe i ill consider geting x86-64 macbook above ARM one if termal throttling is not an issue

[dapper musk]

oh thats bad

grep -w -- $dm $newFile | head -1 >> "$shortFile"
be written as
grep -w -- $dm $newFile >> "$existingFile | head -1 >> "$shortFile"

[dapper musk]

use tee

to do so

[amber garnet]

Like @dapper musk wrote, it can be done with tee

grep -w -- $m $newFile | tee -a "$existingFile" | head -1 >> "$shortFile"

Not tested!

Hello , I've been facing a little trouble with vim recently , when p is pressed after space immediately , it shows <Plug>PeepOpen , so I have to wait for a second before typing p for it to work normally , is there a fix to this?

[main olive]

Not change I mean to reach

why each time getting need permissions?

I am at home fodler

[formal schooner]

@main olive can you show what command you are trying to run, and the error you are seeing?

@tender plinth it looks like you installed a plugin that assigns <plug>PeepOpen to p . does this only happen in normal mode? try :verbose map p to see which plugin did it. i really dislike plugins that automatically override standard mappings...

[tender plinth]

yeah it happens in normal mode

this is the output of :verbose map p

[main olive]

how I can check if database is created?

[formal schooner]

it looks like vim-yankstack did it then. remove vim-yankstack or consult its documentation to see if there is a way to disable the mapping

[tender plinth]

yeah thanks alot!

[main olive]

Hi, I'm currently trying to install python3.9 on a debian server. I have read that I should add the repository ppa:deadsnakes/ppa. However, apt tells me that

N: Updating from such a repository can't be done securely, and is therefore disabled by default.```

Should I set allow-insecure=yes or is there a better option?

[harsh owl]

Gudrun: cant you just edit the sources file and s/http/https, then apt update? or thats what i would try anyway

[main olive]

you mean sources.list?

meh I don't think I'll keep trying since the only reason I needed python3.9 was brand new builtins like str.removeprefix() but I just wrote that myself now

But I'm not quite sure what you mean - how would manually entering the repository make it more secure? Like, for what reason would apt stop complaining?

[harsh owl]

godlygeek: in /etc (something like /etc/apt/sources.list.d) there are files that contain the links to repos apt uses

sorry godlygeek mean @Gudrun :)

anyhow - http is plaintext, https is secure

[main olive]

yeah I get that

oh so you mean I should just enter https?

[harsh owl]

right exactly

[main olive]

well, I would just like to remark that when I enter that in my browser, it appears to not have a valid certificate

so that'd probably not work either

[harsh owl]

interesting - anyway, like i said, thats just what i would try. not that its guaranteed to work. its been a while since i used ubuntu, switched to arch linux a while back

[main olive]

well as I said I've already implemented the python3.9 function I needed myself

thanks for the help though

[harsh owl]

cool. yea that ppa seems like a bit of a mess tbh looking at it

one of the reasons i like arch; many things are packaged well. yet to not find anything i wanted in aur. they are on python3.9 already by default which is nice

hi

how to allow remote connection to sql server 2019

so that i can access it through windows

[loud ginkgo]

the remote instance of sql server doesn't allow external connection by default?

in practice usually if you want to dev locally you would connect to the db via tunnel node for extra layer of security

[amber garnet]

As far as I know by default servers use localhost to handle incoming connections - which means that only local machine is able to connect

[amber garnet]

If you developing something locally why do you need extra node as a proxy?

[loud ginkgo]

oh he mentioned remote so I assume it's outside his local network

but if you can, use postgres. sql server doesn't scale that well

[amber garnet]

Then he need to have static IP

[amber garnet]

https://docs.sdl.com/801922/570899/sdl-tridion-docs-13-sp2/microsoft-sql-server-ports

Enable remote connections to your SQL Server.

Open SQL Server Management Studio.
Right-click your server's name and select Properties.
Tick the checkbox Allow remote connections to this server.
Select OK.

Open ports as well

[loud ginkgo]

oh yeah you can only allow certain IP to connect. but in production usually someone will set up vpn or tunneling for you to overcome local dynamic ip issue

[amber garnet]

Right, it seems that it can work

[main olive]

set GRUB_DEFAULT to gradua

GRUB_TIMEOUT to 0

GRUB_DISABLE_OS_PROBER to true if gradua eaven have it instaled (it is not nesecary)

How do i detach from a tmux session? Ctrl B + D isnt working for me

[loud ginkgo]

ctrl b + d should exit to a normal shell. wdym

[tender plinth]

Hello , I've started using tmux just a while back , and noticed that when u enable the mouse mode , u cant select text normally like we do in bash , so is there some work around that I could add into my configuration to select text even with the mouse mode on?

[trail lodge]

Hold shift whilst selecting

[tender plinth]

yes , but thats clumsy compared to normal text selection on a terminal right

[trail lodge]

A little, but that's the price of having mouse mode enabled. You could create a command that toggles mouse mode on and off

[tender plinth]

like multi line selection with mouse can be done with double click on normal bash , but in tmux , its not really good

[trail lodge]

If you press and hold shift you can still do that

[tender plinth]

well , that doenst happen with me , im not really sure why

On ubuntu I did a force unmount of ext4 partition of my main drive now I cant do anything wont shutdown terminal wont open chrome wont open only like calendar opens

[dapper musk]

so unexpected how anyone could guess that when you basically did equivalent of disk unplug system would break?

never use --force if you do not know what you are doing

[harsh owl]

BarneyLovesYou: you will need to reboot, i suggest having a recovery method such as a usb boot drive or dvd so you can fsck the drive. ext4/xfs are fairly hardy, you might lose a little data though, depends on what you had going on. the longer you leave it running likely the worse things will be, especially if you open anything important and try to write it

[urban minnow]

I installed ubuntu today, nothing important was on the drive is the good part, I was trying to make a windows bootable usb. the tutorial said to unmount ext4

[dapper musk]

good for you. next time read errors and do not use --force 1st

[harsh owl]

yea --force is almost always the wrong option. though i recently quit a job and my last command was sudo rm -rf /

[dapper musk]

and if you are doing anything with disks make sure that you are working on disks that you are sposed to do(fdisk comes handy here)

[dapper musk]

lol i guess you didn't like them especially

Guys, I am trying to turn a normal TV with a USB and HDMI ports into a smart TV. What Linux distribution would be suitable? Also what could make the screen of the TV interface with code on the flash drive?

What I found from research:

1. There doesn't seem to be anything similar.
2. The other alternatives were a dongle (Chromecast, Apple TV) or just plugging in an HDMI cable from a PC which is not very exciting.
   Edit: Also the TV manufacturer also does not provide an API and I couldn't find how the multimedia player on the TV was made.

hi

i have a linux

and i want to code in python

i can do the basic stuff from terminal

but cant do turtle and tkinter

when i download python from the browser

it shows a lot of files

i dont really know what to do next

can anyone please help me

pls ping me if u reaply

[amber garnet]

Which distribution do you have?

[wise valve]

ubuntu

[amber garnet]

You can try to install python3-tk by executing

$ sudo apt-get install python3-tk

[wise valve]

zdr

[amber garnet]

What does it mean?

[wise valve]

sorry that was typed by mistake

[amber garnet]

Oh, okay

[wise valve]

it says command not found

[amber garnet]

Which command?

[wise valve]

$ sudo apt-get install python3-tk

[amber garnet]

Paste without $ sign

[wise valve]

ok

[long pilot]

why apt-get if you can just apt

[amber garnet]

I wanted to show that you should execute this command in the terminal

[wise valve]

its downloading something now

[amber garnet]

You can, ofc

[wise valve]

its finished now what

[long pilot]

try launching python from the terminal i guess or something

[wise valve]

i did

but i still can use the turtle module

[amber garnet]

Try it

Paste your code

What are you trying to execute

And error message if appears

[wise valve]

just trying to import the turtle

[wise valve]

there is no error message but also no canvas arrises

[amber garnet]

You need to execute code, not just import

[wise valve]

the command is
import turtle

ohk then

[amber garnet]

Try it

from turtle import *
color('red', 'yellow')
begin_fill()
while True:
    forward(200)
    left(170)
    if abs(pos()) < 1:
        break
end_fill()
done()

[wise valve]

but in the book im using says that a canvas will appear when i import turtle

[amber garnet]

This is example from this page https://docs.python.org/3/library/turtle.html

[wise valve]

TYSMM IT DID

[amber garnet]

Yay, nice

[long pilot]

pog

[granite aspen]

I was able to safely kill them and reboot

simplifying yes but they do not use arrays

here is diagram how it works

(btrfs)

meanwhile in UFS(unix file system) directories are just files

containing pointers to files inside it

so more like linked list

[proud dagger]

i want to put a python script in /usr/local/bin so everyone can use it. it has a dependency.

1. Is making a virtualenv with that package installed and pointing the shebang line to it the correct way to make it go?
2. If so, where is the linux-iest place to put that virtualenv? Something under /usr seems right, but I'm not sure.

[rugged swift]

For /usr/local/bin, I personally tend to put it at /usr/local/share/{my-app-name}. But I don't know; I'm not an expert at this.

[warped nimbus]

Is making it a package that's installable with pip not the direction you want to go in?

[proud dagger]

it is pip installable. but i don't want to install it (or anything for that matter) into the system python environment

also i don't want it to stop working if someone has a different virtualenv active. i want it to work as easily as any other system executable

[warped nimbus]

You can do a --user install. If you want it available for all users then I suppose the "proper" way is to create a package that is compatible with your distro's package manager. At least that's what I do on Arch. I don't know if that's too annoying on other distros.

[proud dagger]

cool, i appreciate the replies!

[ionic goblet]

Pretty stupid question but how can I install the default windows 10 font, I think its segoe ui? to my ubuntu machine? i am missing alot of emojies and other stuff

[urban minnow]

are directories a file?

i like that you have us see a man using a urinal as a profile picture very very nice :kappa:

@main olive check out https://discord.gg/ubuntu

[granite aspen]

I can't tell if the progress bars mean anything or what I'm supposed to do. Clicking "Ok" does nothing and there's nowhere to enter commands.

I'm just trying to install virtualbox.

oh something is happening

[dapper musk]

virtual box can have major isues with secure boot

if you do not need it then well disable it

[clear swan]

what distro/os is that?

[karmic grove]

how do install CGICC on linux

[foggy quiver]

I'm installing pop! Os right now, and I need to know what the /boot partition is. Can anyone help me with that

[blazing wolf]

do you guys use any noise cancellation software in linux? if so, which one?

[inland gulch]

You mean like motherboard fan speed control or audio signal processing?

[blazing wolf]

the latter

like krisp

which discord uses

but is not available on linux

[inland gulch]

UbuntuStudio has a serious collection of apps for the later, most are available on any debian based build with ease of installation

@blazing wolf you could try a parametric eq from https://calf-studio-gear.org/ allows you tune out some annoying frequencies. Probably require a lot more processing to reproduce what krisp apparently does.

[blazing wolf]

alright, I will check em out, thx 👍

[main olive]

yo

[quiet ice]

try ifconfig

[main olive]

i did

thats what it showed me mate

look at the screenshot

the circled thingy is my machine IP addy right?

[quiet ice]

yeah thats the vpn ip pretty sure
if you werent connected on a vpn you would see something different

[main olive]

damn bruh

[quiet ice]

so, in this case, that would be your ip

[main olive]

i aint even connect to no vpn

[quiet ice]

odd..

[main olive]

hold on

uh wtf

it says im from washington

even doe im not

ya its a vpn

but i aint conencted to one

aight homie i was connected to an extention vpn on mi browser

[quiet ice]

ok im pretty sure thats ur local ip, not ur public ip used to connect to the Internet
so in your home, you have connections between others in the same home

that ip is used to identity you in that space

[main olive]

thats fosho my public ip

but thats the error i get

when i run the script

[quiet ice]

delete that

[main olive]

yeah i dont care

tbh

i just need help bruh

[quiet ice]

but yeah the thing you circled is your machine ip

[main olive]

must be tuple not str

[main olive]

ok

ok

hold on wait

[quiet ice]

oh

wait

it should be

sock.bind((<ip str here>, <port>))

you had a type error thats all

[main olive]

str for what wait?

can u gimme a better example

with an ip and port

socket.bind(('1.1.1.1, 8080')) like that

[quiet ice]

look
https://docs.python.org/3/library/socket.html#socket.bind

[main olive]

kk wiat

[quiet ice]

more like
socket.bind(('1.1.1.1', 8080))

[main olive]

oh

oh my god im dumb asf homie

[quiet ice]

did it work?

[main olive]

i thought i made a mistake

that was my original one

then i was like oh wait the single quotes suposed to have the port within them too

so i extended it lol

damn bruh

ty

[quiet ice]

nah it takes a tuple,
ip for str and port as an int

[quiet ice]

np

[main olive]

yessir

it works now

[main olive]

got it

[quiet ice]

nice

[main olive]

.close

!close

or not

xd

If you try deleting old python3 version from ubuntu desktop....half of your systems get erased in addition.

Almost same as deleting /

Hi

Help me pls

[wise forge]

not really enough of information

except that I can see some unit tests failing

[main olive]

Yeah but what reason they failed?

[wise forge]

possible reason, wrong command to launch tests

[main olive]

I did these steps

[wise forge]

uh, i used only just unittest and pytest

I didn't use tox yet

[main olive]

Unit test also failed. Cover was 8 percent

So I found this code reading file metadata that Windows keeps. https://stackoverflow.com/questions/12521525/reading-metadata-with-python

But I want to do that with metadata kept by Dolphin on Linux. Any idea where I can find this metadata?

If you search this, all you find is people who want permanence to their tags and ratings in dolphin, or people who cant get metadata to show.

What I want to know is where that metadata that is has can be found

Google dolphin file metadata location -tags -ratings didnt help

If I could read that data rather than process the files it would save me time.

[dapper musk]

by metadata you mean this?

if so you can use os.path

for time, size, name

[finite crater]

More like stuff like this

os.stat information is pretty easy to get, but this kind of information requires me to open the file, process it in some way, and sometimes that is time consuming.

If this data already exists, it must have a location somewhere.,

This program is Dolphin.

[dapper musk]

pathlib pure path do not require this and idk that dolphin have

any python integration

or any integration with any pl

[finite crater]

But, dolphin is a linux program, its made up of files, and they must exist somewhere.

[dapper musk]

what png image etc is in ram

it is not saved

yes evrything is file but idk if you want to mount your ram and search for dolphin

[finite crater]

How does it know the height and width of every file without opening every file and determing this?

no i dont lol

or perhaps, does it open every file to display this info

[dapper musk]

you can check source code

[finite crater]

fair enough. No one has ever asked this before, anyone who has anything to say about KDE and metadata is only there to say, "I dont have metadata"

I might try that.

but I dont follow C++ very well.

[dapper musk]

i found this

[finite crater]

Im looking through the code now looking for the Detailed View stuff

[dapper musk]

https://stackoverflow.com/questions/15800704/get-image-size-without-loading-image-into-memory

it loads as fiev bytes as possile

[dapper musk]

did you found anything?

[finite crater]

Its possible that getting the file dimensions and type this way is not even as taxing as other stuff that I cant get any metadata on... like opening videos to determine the frame data, like fps and frame count, which takes significant time to do for each file.. Right now im using cv2 to do it.

And to be honest, dolphin isnt even showing data like aspect ratio and fps for many files, so I might not be able to get it that way as easily as I would have liked.

-- as for the Dolphin code, no... I think its probably here tho https://github.com/KDE/dolphin/tree/master/src/views

[dapper musk]

dolphin acctualy loads them

[finite crater]

but yes

this magic module is a good idea to look at

how to share clipboard, in gnome boxes virtualized oses?

http://www.linuxandubuntu.com/home/walkthrough-on-how-to-use-gnome-boxes

found this almost useful guide

but I don't get it, am I supposed to install those tools inside the box in order to run?

tried it already many times, but it is not looking to work (I have Ubuntu 20.04 desktop and tried to virtualize Ubuntu 20.04 Server)

[wise forge]

already

[main olive]

tox -e tavern -- --workers auto --tests-per-worker auto --durations=0

[wise forge]

trying exactly virt-manager at the moment

[wise forge]

thanks for advice anyway)

it makes me reassured

that I am walking right way

https://media4.giphy.com/media/sEJ2j80ZmgXPOlEYEt/giphy.gif

can it be run on server, where I have only console?

first tool I need, will be only for desktop

erm.
well, the main objective for myself in Ubuntu Desktop
Secondary objective... to have the same in Debian Server

yeah

already installed and trying

is it only redirecting traffic? or I could directly install on server with thing above?

after installation, would be virtualized instance of image still running on server after I killed ssh connection from my desktop?

great

and if I am using Image ISO from my local pc

is it transfering it to server?

well, no problem

thank you very much

I learned so much

and this is tool to learn even more

crazy run of learning!

virtual sandboxes are quite cool things to play with)

[warped nimbus]

That is the most horrific thing I've read in a while

I'm interested, why do you use bash for somethingthis complicated? Do you actually like the language?

In most cases I would much rather use a language like Python or hell, even PowerShell.

I find it difficult to write safe bash code - properly handling errors, checking exit codes, etc. It's really clumsy in that regard.

And the fact that values can't really be returned from functions - have to serialise them to a string (which is especially annoying for data structures like arrays and dicts) or use global variables.

Syntax is a bit complicated and language has many gotchas, but shellcheck helps immensely with that.

I understand it can work cause I've done it myself, but it was quite the journey. It's only something I'd use if I feel masochistic.

[main olive]

if theres anyone familiar with kde plasma or kde neon, what is a notification catcher and how do i use it, also a friend suggested me to use a notifcation catched as whenever I use discord app it freezes

Hello , I've been trying to understand how linux memory management works and came across this kmem_cache_alloc_trace function , tried looking at it's source code but couldn't make sense of it's basic function , can someone give an insight into this?

[main olive]

@main olive @wise forge Hello, please only send messages relevant to channel topics. We have a #bot-commands channel to test out commands. Sorry about the double ping

[untold abyss]

quick question

if 7z is showing 4 processes (htop) does it mean it's using multiple cores, or it's just something else?

I am extracting a 90GB zip and it's taking atleast 2 hours

[warped nimbus]

htop does show threads by default

You can press H to hide them

[harsh owl]

Awesome_Ruler_007: not sure on htop, but with top if you have a multicore machine you can just press 1 to display all the proc info. or start with top 1

[naive path]

What's the difference between the command python3 and sudo python3?

[harsh owl]

sudo is how you run commands with superuser privileges. so it causes python3 to run as superuser. generally not what you want

[naive path]

Oh, thanks

what are the commands that will need super user privileges?

[harsh owl]

generally stuff like installing packages system-wide, rebooting, configuring network/storage etc

stuff that would impact other users of the system tend to require admin privs, since these systems were designed to support multiple users

[torn forge]

i am hosting a postgres database on a VPS and i was wondering what the best way to access it would be through my local machine. an SSH?

[harsh owl]

hale: yes, just ssh in, you dont want to punch a hole through firewall and expose the db to internet. unless perhaps you have a static IP, but even so not advisable

[amber garnet]

Are you asking about accessing VPS or database?

[chrome forge]

It is good to use it in mostly all commands, cuz thats how u can get all possibe info

enter the sudo mode by running sudo su, then use ur commands

[amber garnet]

Hmm, I can say nope. You shouldn't run everything by using root account or admin privileges

[wise forge]

making script that makes dump from database directly, I think more easy solution

depends on your database size/security things and e.t.c.

ssh is not bad solution too ;b just more steps to do in some cases

[chrome forge]

Maybe, its just my second day since i shifted to linux

[amber garnet]

You can create a huge vulnerability by doing everything with sudo

[chrome forge]

oh

[torn forge]

@harsh owl If I am correct I need to setup my postgresql database for SSH as it is not able to be accessed by default?

[harsh owl]

hale: postgresql isnt what provides ssh. what kind of vps? does it have an actual OS? that is what you would ssh into. you can also do stuff like port forwarding over ssh into vps to access the db directly on your local machine. like a proxy

[torn forge]

@harsh owl It's a Vultr VPS running Ubuntu 20.04, I want to SSH to my local machine

I'm fairly new to the devops stuff. I know how to navigate Ubuntu but the networking side of things I haven't quite figured out yet

[harsh owl]

how are you trying to use the db? if you just need cli access, you can ssh into vultr vps and connect to db there. if you want to access db from your laptop or whatever, i would suggest ssh port forwarding rather than opening postgresql port to internet

it looks like they open ssh by default; https://www.vultr.com/docs/how-to-access-your-vultr-vps - so you'd just need to know the IP and creds

[torn forge]

I would like to connect to it via pgAdmin

So you for that I believe i would need to SSH port forward?
