[forest furnace]

yeah, strip would trim both sides though

[main olive]

oh i see, stdin includes a new line
.rstrip() seems to work thank you

[forest furnace]

sometimes its a good idea to try things out in the REPL and use repr(by just entering "line" at the prompt) to see how variables actually look like, in which case you'll notice there's a \n at the end ;)

[formal schooner]

you can also .rstrip('\n') if you only want to remove newlines but not other whitespace

!e ```python
import io
for line in io.StringIO(' a \n b \n\tc\t'):
print(repr(line.rstrip('\n')))

[shy yoke]

@formal schooner :white_check_mark: Your eval job has completed with return code 0.

001 | '  a  '
002 | '  b    '
003 | '\tc\t'

[forest furnace]

!e

print(repr("\n\ncontent\n\n".rstrip("\n")))

[shy yoke]

@forest furnace :white_check_mark: Your eval job has completed with return code 0.

'\n\ncontent'

[formal schooner]

!d str.rstrip

[shy yoke]

str.rstrip

str.rstrip([chars])```
Return a copy of the string with trailing characters removed. The *chars* argument is a string specifying the set of characters to be removed. If omitted or `None`, the *chars* argument defaults to removing whitespace. The *chars* argument is not a suffix; rather, all combinations of its values are stripped:

```py
>>> '   spacious   '.rstrip()
'   spacious'
>>> 'mississippi'.rstrip('ipz')
'mississ'
```  See [`str.removesuffix()`](https://docs.python.org/3/library/stdtypes.html#str.removesuffix "str.removesuffix") for a method that will remove a single suffix string rather than all of a set of characters. For example...

[forest furnace]

oh yeah speaking of which, did we add a strip tag recently? So stripping out multiple characters wouldn't work like one would expect, .removesuffix would work for that (unless one specifically want to strip any of the multiple characters provided)

[formal schooner]

!strip

[shy yoke]

Did you mean ...

string-formatting
f-strings

[formal schooner]

hm

yeah that's a common "oops i didn't read the docs" trap

probably happens to everyone at least once

i know i did it

[main olive]

using repr is a good point too it makes it really obvious what's happening

[unique tundra]

I just installed pymouse through pip

when I try to import it I get

import pymouse
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/phzoz/.local/lib/python3.9/site-packages/pymouse/__init__.py", line 95, in <module>
    from unix import PyMouse, PyMouseEvent
ModuleNotFoundError: No module named 'unix'

but like, import pandas works just fine

[main olive]

we dont write the code for you

but we can point you in the right direction

commands you need are

find, grep and xargs

or you could use for bash syntax

to iterate over the results of first command (the one that actually finds the files) and then javac for each

[unreal sinew]

@red prawn that is quite simple. Also see kinguard's responses to you

[red prawn]

And anyone else who feels like helping also is welcome to

[red prawn]

Can i use kali to type these commands into the terminal if i dont have mac, or will this not work? Just to know i have the correct answer?

/what would you use if you were on windows

and i dont want you to write the code for me, its an activity so its important i understand each line im writing and be able to know what each one is for

Nevermind, i found a free online linux terminal

This is an optional activity, i want to try and do atleast these two examples

[unreal sinew]

@red prawn like Kin said …

we dont write the code for you
but we can point you in the right direction

[red prawn]

do you guys have other interesting unix commands that come to mind, that are 1 line but incorporating different components that i could go off and study different from this so i can kind of get a grasp of the thing? Im tying to make my learning funner. Thanks.

or links/resources which discuss interesting ones

[warped nimbus]

If you're writing any shell script, I suggest you start with set -euo pipefail at the top. If you use bash (a modern-ish version, like 4.4 and higher or something), also add shopt -s inherit_errexit as another line. Not sure which other shells support inherit_errexit.

-e make the script exit when a command fails. -o pipefail makes this also apply to any command along a chain of a piped commands, rather than only checking the command at the end of the chain. -u makes it error out if an unset variable is used. inherit_errexit makes -e also apply to command substitutions.

Basically, these options make error handling more sane and avoids scenarios where your script has an error but keeps trying to run regardless.

If that's confusing, maybe the examples in here will help https://coderwall.com/p/fkfaqq/safer-bash-scripts-with-set-euxo-pipefail

This tool is also very useful for improving your shell scripts https://www.shellcheck.net/ You can learn a lot from your own mistakes with it, since it has detailed explanations of many errors (examples, justifications for them being considered errors, and solutions)

[red prawn]

i thought this would be a good way to move forward but i think im getting more confused 😆

[warped nimbus]

I know it didn't directly address your question but I figured these are good tips for anyone writing shell scripts.

And well, I would consider more sane error handling as something that makes your learning more fun

[lilac hill]

hello, i'm trying to run this repo: https://github.com/dsys/match#development locally, but i can't seem to run it with docker. when i try docker run -e ELASTICSEARCH_URL=http://localhost:9200 -it dsys/match it's just stuck and doesn't do anything

[ember quiver]

Did you run the make command and did it show any errors?

[lilac hill]

i managed to run it with make. but the url is not accessable it doesn't load http://0.0.0.0:8888

[ember quiver]

That's not a valid IP. If you're trying to reach a local instance try 127.0.0.1 instead of 0.0.0.0

[lilac hill]

i tried running it with make dev so elasticsearch started inside docker and i can access it now

but i can't make post requests for some reason

r = requests.post(f'http://0.0.0.0:8888/add?url={image_url}')
print(r.json())

this gives response: {'status': 'fail', 'error': ['bad request'], 'method': '', 'result': []}

[ember quiver]

See my previous comment about 127.0.0.1

[lilac hill]

so change 0.0.0.0 to 127.0.0.1?

[ember quiver]

Yes.

0.0.0.0 typically means "any IP" so it's used in config files but it's not valid to post a request to

[lilac hill]

it still gives me {'status': 'fail', 'error': ['bad request'], 'method': '', 'result': []}. i think i'm making the request in a wrong way

this is how they explained it in docs

get requests work so i'm making the post request in a wrong way

[ember quiver]

Yeah, makes sense. See if this helps: https://www.geeksforgeeks.org/get-post-requests-using-python/

[lilac hill]

what do they mean in filepath?

i think skipping it is the reason it fails

[shrewd stratus]

it also means all interfaces in some contexts (e.g. address binding in a container)

[ember quiver]

The link I shared shows you how to post parameters, I think it goes there

[lilac hill]

i followed some functions and path is the same as url

but it still gives me the same error

[ember quiver]

Show your code?

[lilac hill]

params = {'url' : image_url, 'filepath' : image_url}

r = requests.post(f'http://127.0.0.1:8888/add', params=params)
print(r.json())

this is the response: {'status': 'fail', 'error': ['bad request'], 'method': '', 'result': []}

this is the function that handles /add request

path is the same as the url but why isn't it working then

[main olive]

of course, those commands are for any UNIX based system including any linux distribution or MacOS

[main olive]

update: i think rebooting fixed it

[main olive]

@main olive i believe .profile doesn't always activate

use .bashrc

the latter is guaranteed to be source'd when you open a new terminal

[tough sky]

Hello i am a little confused with pip, where is it meant to install packages? on **/usr/lib/python3.9/site-packages **or in **~/.local/lib/python3.9/site-packages **? Both of these directories are populated with packages.
i install packages like that python -m pip install <package>

[warped nimbus]

The first directory is the global site. The second directory is the user site. If you run python -m site it will show these directories.

[tough sky]

i did something bad

[warped nimbus]

pip install ... corresponds to the global site. pip install --user ... corresponds to the user site

[tough sky]

i read a post that global packages should be install with a package manager and user with pip preferable

so i delete both of them : D

to set it up right

[warped nimbus]

Yes, I was just about to mention that

[tough sky]

and now almost everything is not working

[warped nimbus]

I'm not sure why you decided to do that

[tough sky]

"to set it up right" idk im dump

[warped nimbus]

The system's package manager also installs packages to the global site.

[tough sky]

yea...

but how do i know what is missing now?

im missing about 23 packages

[warped nimbus]

Is your package manager working?

[tough sky]

yea

im missing 23 python-packages

[warped nimbus]

Use it to list your installed packages, and look for ones that have python in their name

Those will be the ones you're missing

If your package manager is working, maybe you can just ask it to reinstall those packages

[tough sky]

im just not sure what packages i should install with the package manager and what with pip

packages that are required from tools like ranger, should be install with pip or pacman for example ?

[warped nimbus]

I use the package manager for most tools, but I have a few things installed with pip install --user like poetry. One advantage is that pip gets the new updates for packages sooner. However, it seems to mostly be a "philosophical" distinction, since you're probably the only user of your system. The distinction is whether you want the installed Python package to be available to all users or only to your user.

As for any libraries I need, I always create a new virtual environment specific to the project I am working on.

[tough sky]

ok thanks ill look more into it later i gtg now

[tiny lava]

@heavy cloud Not super familiar with the specific technologies are using, but have you tried manually editing your .xinitrc to start mate rather than gnome?

err wait this is ubuntu

As far as I know mate and gnome shouldn't conflict so you probably have both of them installed, are you not seeing mate in lightdm?

as for the audio issue, does this help?

https://askubuntu.com/a/811123

[tiny lava]

https://wiki.ubuntu.com/LightDM#Changing_the_Default_Session

For the audio, it's worth checking that it isn't muted somewhere. I remember having an issue a while back where the output I wanted to use was muted in ALSA and I had to install alsamixer to unmute it

[granite whale]

import subprocess
AGE = 30
subprocess.run(
                ['notify-send', '-t', '30000', '"He is $AGE"'])

Any idea to make the notification "He is 30"?

At the moment $AGE can not call the value of the variable "AGE". Guess coz it can not know a variable defined in python

[wise forge]

import subprocess
AGE = 30
subprocess.run(
                ['notify-send', '-t', '30000', f"He is {AGE}"])

A bit of string interpolation

[granite whale]

Wow, this really works. I thought about f string then I thought that wouldn't work at all since it's a python thing. Strange

Thanks

[formal schooner]

the f string is processed by python before sending it to the subprocess. so the subprocess just sees He is 30

[left dirge]

I've recently dual booted and installed ubuntu 20.04.3 LTS on my computer. Now for some reason my amd gpu is not showing on the plaidml-setup which means when i do machine learning stuff it won't use my gpu which will slow down the process so can anyone tell me as to how i can make plaidml-setup see my amd gpu in ubuntu as it works fine when im using windows 10

[queen merlin]

You probably need to install the official amdgpu driver.

For instance run this lshw -c video to see what video driver is currently being used. Probably a generic one that doesn't support the gpu itself and is basically just providing basic video card support.

[left dirge]

does anyone know how i can fix E: Malformed entry 1 in list file /etc/apt/sources.list.d/rocm.list (Suite) E: The list of sources could not be read.

[formal schooner]

Post the contents of that file

!paste

[shy yoke]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[left dirge]

oh i was jsut trying to do sudo apt install gpart and it gives me that

[lavish storm]

be sure to # apt update before installing

could you cat the file of interest/

how do i do that?

does anyone have a good book/web/video source thats an introduction to mpi and parallel computing? im second year cs student and my school just got new hardware they are going to use for parallel computing I have an option of getting it set up as my final in my class. I know they want to use cuda with the gpu and ive never touched that before so any tips and direction would be helpful!

[austere sail]

so i'm trying to uninstall and then install again ubuntu on my pc as it was getting some errors and i thought that the only way to fix it was to uninstall and reinstall it, i followed this video:https://www.youtube.com/watch?v=KwcfzCfkQgc which was basically free up the partitions where ubuntu was located and then do some commands in the command prompt. for some reason after doing all this i can still see the option to use another os when i do shift+restart and when im booting up my pc. i also tried using f10 and then installing ubuntu again using my usb but the only options i see is [noexecute=optin] also if i do bootrec /scanos i get 0 in the no. of windows installations

[main spear]

Hi, I have two fundamental questions:

1. Do I understand "hostname" correctly? It is a string that is supposed to uniquely specify each of the nodes in a network? If yes, then what happens if two hostnames are the same? And also how can it be useful in the network? Nodes use IPs or Domains to communicate, right?

2. How could nodes know their FQDN? E.g., socket.getfqdn() in Python gives the FQDN of the node it's running on. But FQDN is specified by a domain name server, right? The machine itself must be unaware of it... (maybe it sends a DNS query to find out its own FQDN and then returns it to us?)

[tiny lava]

1. yes. If two hostnames are the same DNS won't give out the IP addresses for one of the hosts. It is mainly useful so you don't have to memorize IP addresses. DNS translates these hostnames to IP addresses so all you have to remember is a hostname.

2. generally for them to be aware of their FQDN, the DNS suffix for their network needs to be configured on the device. Then all the host has to do is append that to their hostname

[green gale]

i have some problem in installing node in my mac, can someone please help me ?

[queen merlin]

Yes. Don't do it that way.

Install homebrew.

Use homebrew to install nvm.

Rejoice.

or just use homebrew to install node, but you'll be happy you got nvm as it hellps you keep node up to date, install different concurrent versions, etc

wait, is it nvm or n ... hmm, I'd have to go look.

So at least use homebrew to install node (and you should use homebrew in general, it'll make your life easier)

Okay, I double checked, n and nvm can be used for managing node versions on your computer. I've only ever used n but both seem to do the same job.

https://www.npmjs.com/package/n

```anyone know why it would print 200 instead of 600 here?

[sudden moon]

maybe it has a maximum of 200? never used pyttsx3

that's all I can think of haha

!pypi pyjnius

pyjnius v1.4.1

A Python module to access Java classes as Python classes using JNI.

[main olive]

wow

[formal schooner]

better yet, don't use slow-ass nvm. use fnm, volta, or n

i'm actually astounded at how slow nvm manages to be

you could also use asdf-vm

or even homebrew, macports, nix, or pkgsrc

Yeah I personally use n but my brain always wants to call it nvm.

[gleaming wadi]

i made a bunch of nifty aliases and functions for the unix shell

the top two are Preocts' lines of code, the rest is mostly mine

export PIP_REQUIRE_VIRTUALENV=true

gpip() {PIP_REQUIRE_VIRTUALENV=false && pip "$@"}

pip-all() {pip install -U $(pip freeze | awk '{split($0, a, "=="); print a[1]}')}

gpip-all() {gpip install -U $(gpip freeze | awk '{split($0, a, "=="); print a[1]}')}

}

@eternal falcon how do i add arguments to a function in shell script? cause now i have two separate functions to install a venv for 3.9 and 3.10 yet they do the exact same thing, and i want to combine the two

[eternal falcon]

My bash-fu is not the greatest. $1 $2 $3 pull each argument by space. $0 is the name of the script. $* will be all the arguments.

[gleaming wadi]

got it, thanks!

[formal schooner]

there is also $@ which behaves differently from $* but i can never remember the difference

$0 can also be the name of the current function if it is a function and not a script

https://stackoverflow.com/a/3898681/2954547 ah right

i almost always use "$@" (but i also use zsh where the parameter expansion logic is generally a lot less chaotic)

[eternal falcon]

Good to know. I need to brush up my knowledge a bit. I only knew $* because of my todo alias I use at work

touch /mnt/c/Users/-----/Desktop/"$*"

[shut tusk]

why is Gnome shell called Gnome Shell ? Its not like bash or zsh

a "shell" can be broadly defined as "a program that lets you interact with your operating system" - so it's a graphical shell. windows uses the same terminology, explorer.exe is the "windows shell"

[wet nest]

Hey, I'm looking forward to use rev in a shell to rev a string/number, but its not working for some reason, I've looked over the internet as I'm fairly new to Bash Scripting, but couldn't find an example of a bash script with rev. Helps appreciated.

[summer trail]

Try:

#!/bin/bash
inp=$1
reverse=$(rev <<<"$inp")
echo "$reverse"

Or alternatively, you could do:

reverse=$(echo "$inp" | rev)

@wet nest

[wet nest]

Thanks a lot mate, really appreciate that.

@summer trail

[summer trail]

👍

[wet nest]

btw can I ask what resources have you used to learn bash scripting?
Like books or online video contents(udemy, YT etc)?

[formal schooner]

practice + reading the man page

[summer trail]

I learned so long ago I'm not sure I can say. The Advanced Bash Scripting Guide was a major resource for me, I remember.

And yeah, I've definitely read the entire bash man page repeatedly. And the opengroup sh standard.

[wet nest]

Thanks a lot for the help.

[patent osprey]

hello can someone explain me how i can change the taskbar in ubuntu

[livid scroll]

taskbar?

do you mean the dock

[patent osprey]

yeah

it's so different to windows

[livid scroll]

which has all the icons of apps

that?

[patent osprey]

the applications button is at the right

[patent osprey]

yeah

[livid scroll]

ah yea that

so what do you need to do

[patent osprey]

i removed the top one by an extension

[patent osprey]

to move the show applications button from right to left

[livid scroll]

well i tried to do that before

[patent osprey]

and do u know how i can put more shortcuts

like ctrl v for paste

[livid scroll]

i don't know how to move the button

[livid scroll]

isn't it already ctrl v by default

[patent osprey]

so you are just used to that button on right?

[patent osprey]

no ctrl v does nothing

[celest salmon]

It is CTRL + SHIFT + C for copying from terminal, and CTRL + SHIFT + V for pasting to terminal

[livid scroll]

^^^

[patent osprey]

oh ok thx

[celest salmon]

CTRL + C and CTRL + V for everything else

[livid scroll]

terminal shortcuts are very different from windows

[patent osprey]

it didn't work terminal not other apps

how can i take a screenshot and use snipping tool

[livid scroll]

use the screenshot

screenshot tool

it comes with ubuntu right?

[celest salmon]

It's quite limited

[patent osprey]

is there a shortcut?

[paper moon]

I think Ubuntu uses GNOME. So you should try this extention https://extensions.gnome.org/extension/1160/dash-to-panel/

[celest salmon]

CTRL + SHIFT + PrtSc

[patent osprey]

omg tysm it looks so much better now

[patent osprey]

is there a way to change the shortcuts?

[paper moon]

Yeah theres a "Customize Shortcuts" in the settings app, under Keyboard.

[patent osprey]

btw the super button means the windows button right?

[celest salmon]

Yes

[patent osprey]

ok thx

[patent osprey]

can someone tell me how can i enable that again

Hi guys, I tried install python3 and it is showing me this : python3: symbol lookup error: python3: undefined symbol: _Py_LegacyLocaleDetected

what can be the issue ? I tried googling it but couldnt find anything

*not installing , just the command

[ember quiver]

This came right up for me... How are you trying to install and on what OS? https://stackoverflow.com/questions/47462386/symbol-lookup-error-in-usr-bin-python3-py-coercelegacylocale-in-new-fedora-2

[south yoke]

yes , but it is coerce

and i am not using conda

It is strange coz when i an my venv, python3 command is running, but not when i deactive my venv

*deactivate

[left dirge]

i did sudo apt install linux-image-5.4.0-54-generic linux-headers-5.4.0-54-generic linux-modules-extra-5.4.0-54-generic so and booted in to ubuntu 20.04 with 5.4.0-54 and now when i boot ubuntu it is just a blinking white line on the top left corner on a black screen and then just a black screen

ctrl-alt-f2 will switch you to a different virtual terminal

[river apex]

I am creating a map API on RHEL with wsgi and httpd service

The function save map images in backend on one of the node

but now I have trouble returning the image to user as they can only access the API via the loadbalancer

[vagrant fern]

@river apex do you want to replicate the disk across multiple hosts? use something like drbd to sync changes around - https://linbit.com/drbd/ / https://www.golinuxcloud.com/drbd-tutorial-linux-disk-replication-centos-8/

[river apex]

We have very limited resource in current phase so replicate data may not be our first option

[vagrant fern]

then you will probably want to just proxy any file requests to a single host, right?

[river apex]

Yes, its the best scenario, but we dont have proxy control either

[vagrant fern]

which proxy are you using?

[river apex]

Is there anything we can do on the httpd service level

If network team is involved in the change, we would properly just add an individual junction for node1 and route the url path to the new junction

[main olive]

can u make a request via python using sockets but with a proxy?

[main olive]

hey everyone, I have a question related to the environment for programming. Im a python dev and as my main IDE I use pycharm, I feel myself very fast and confident in it. BUT I want to switch to either vim or emacs because want something new. But I know that to be productive for example in VIm as I am in charm I have to spend a lot of time. Do you think it's the right choice and time investment to switch? Did anyone have such kind of experience and how much time did u spend on all of the configurations, learning hotkeys and other stuff?

[vagrant fern]

no, proxies (assuming you're talking about http proxying) are usually implemented in a HTTP client library

[main olive]

No just a raw socket

[formal schooner]

it took me years of using vim to get effective with it. i started with small things and gradually started using more and learning it more

i switched to neovim several years ago, i think it's much easier to get started with than it was in the past, because the plugins are so much more powerful than the old vim plugins

however neovim is still vim, and yes it will take a long time to get used to

emacs is similar in the amount of time you will need to get "good" at it

both programs are good for people who don't mind a very long learning curve (on the scale of years) and don't mind constantly tinkering with and configuring things

normally i am not much of a tinkerer, but i am now so used to vim/neovim that the tinkering doesn't bother me

once you have the muscle memory and a comfortable setup of plugins/tools, the text editor will start to feel like an extension of your brain

this is true for any highly-configurable text editor: vim/neovim, emacs, kakoune, sublime, etc.

there are lots and lots of other text editors too

you can look into kakoune, micro, joe, acme, or sam

or if you want other ides, check out jedit or wing

some people are highly productive in notepad++ or kate or geany

sublime can be a great platform too (and worth the license fee if you have a job and can afford it)

[stable yew]

i use neovim and using the inbuilt tutor, it took a couple minutes to learn how to write and save files

in an hour and a half or so I finished the entire tutor and am somewhat proficient with it

there is a learning curve to it but it isnt that bad

but yea you tinker a lot with the config

https://github.com/nvchad/nvchad/ you could also use a pre configured setup like this if you wanted

Would XDG_DATA_HOME always be writable by a user?

[blissful fog]

Name a command for Case insensitive search : The -i option enables to search for a string case insensitively in the give file. It matches the words like “UNIX”, “Unix”, “unix”

what can be the possible answer for this?

[lavish storm]

None other than good old grep

[stoic saddle]

Hello

Anyone know command in bash to find à way of à file

?

Please

[north bronze]

readlink

[lavish storm]

what do you mean by "find a way of a file"

[ionic goblet]

find /directory/to/search | grep filename

like do you not know what a search engine is

why do people keep asking questions that can be answered easily with a search

[lavish storm]

please respect the coc

[formal schooner]

imo it should be yes

it's the user's own data, usually in their home directory

XDG_DATA_DIRS might or might not be writable because those might be system-wide directories

[formal schooner]

the charitable explanation is that they don't know what to search for. occasionally some users do become "help vampires", in which case the best thing to do is ignore them, or perhaps contact a moderator if they are spamming or disruptive

[frigid solar]

Hi, so i just hosted my Flask website on my VPS, and it runs just fine. But when there is any write operation to the database,
(sqlite3.OperationalError) attempt to write a readonly database This error shows up.
What i do know is that this is something related to permissions, so I just used chown 777 on that database.db file, however, it still gives the same error

How do i fix this error?

[opaque ginkgo]

chown back to root (so you don't break anything) and chmod 777

[livid falcon]

how do i do that?

Im already in root user

and i did give chmod 777

oh, to the entire folder?

[opaque ginkgo]

no

it's still 775 rn

rwxrwxr-x

[livid falcon]

chmod 777 database.db

right?

[opaque ginkgo]

tldr

chown root database.db
chmod 777 database.db

[livid falcon]

Do i have to restart or something after this?

Because it gave the same error

[opaque ginkgo]

what does ls -la display

[opaque ginkgo]

alright it's not a file permission error

oh

the directory needs write perms too

just do chmod +w PersonalWebsite from the parent dir

@livid falcon

[livid falcon]

Ok

oof, same error

[opaque ginkgo]

you don't have any other process es using the file?

check with ps aux

[livid falcon]

I used ps aux but its really confusing for me

It gave a really really long list of stuff

there is no database.db here

Hello guys!

#!/usr/bin/bash

lxterminal -e "/home/pi/project/prog.py"

I made shell script file with contents above on Raspberry OS desktop (lets call it START) and ran chmod +x START in terminal. If i doubleclick START, terminal closed instantly. If I run prog.py via termianl it works in terminal (which is fine, no GUI)
Any ideas why terminal window is collapsing after doubleclicking START?

I also tried adding -i after -e, but it opens hull terminal window, not prog.py

The idea is START is sort of a shortcut for prog.py because I want the prog.py stored in another folder not desctop, but launch it from desktop

[inland gulch]

Are you expecting 'prog.py' to keep a shell open or 'Start' to keep 'lxterminal' open?

[formal schooner]

you might want to exec lxterminal too, instead of just lxterminal

I also tried adding -i after -e, but it opens hull terminal window, not prog.py
what do you expect prog.py to "be" exactly?

you are invoking the terminal

of course that's what's going to happen

lxterm might have some trickery to prevent it from opening another copy of itself

is it possible to use subprocess, so it could remain outputing stdout in realtime to where it is usually outputed, but at the same time to capture stdout result?

[storm rain]

    blockr_process = subprocess.Popen([prog_args.executable, "--dev", prog_args.interface,
                                      "-A", "-F"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
    try:
        for line in iter(blockr_process.stdout.readline, ""):
            print(line.strip())
            parse(blockr, line.strip())

you can iter over the stdout and print + process

i am on a arch linux disto (garuda) btw

how do i fix it?

@heavy cloud

[ripe pilot]

Pretty sure it's changing the theme, fonts, etc. Pretty much changing the aesthethic

[main olive]

i did

yet its still not fixing it

its like called global app menu

idk how to disable it

oh

cd ~/.config sed -i 's/MenuBar=Disabled/MenuBar=Enabled/' *rc

i did that command

and after that

it happend

i tried removing enable to disable

didnt help much

i fixed it

i removed the panel

and it worked

aight

[silver copper]

^^

yeah, its just configuration. make your stuff look cool i suppose or just more pleasant to the eye.

also @leaden lodge yeah I agree, I just wanted to see or hear everyone opinion. I was messing is i3. fun stuff. just need more practice.

yeah the unixporn is just /.config files. shows what they have for an envirmennt

just dont nord on November 😉

[leaden lodge]

I too use i3. Its my favourite wm

Ricing is just making your desktop look more pleasant to the eye by configuring it yourself. Applications such as your wm, polybar or any bar, terminals such as kitty and alacirtty, editors such as vim, neovim and emacs etc can be configured and riced so as to look good. This is how i have riced my i3wm

[silver copper]

Yeah you can switch between the two, just depends on how you set it up. some ppl just run WM, right now Im running both. You can change between the two at the login screen/manager

idk about multiple DE, but you can have DE/WM switch between them

Linux & Python can be a little annoying, but its fine if you know what to install.
Remember to install python3.10, instead of something like python or python3, as both of them are going to install outdated python versions.
so to install python you would do sudo apt install python3.10
This also means you should always use python3.10 instead of python and python3 when running code or just in general using python.

I am talking from personal experience, because me being the idiot I am installed python3.10 not using apt, and then tried to delete system python

No problem! :D

[ripe pilot]

How can i ignore every special character in a echo to a file?

I am trying to write a variable from my program to a linux server, but since it's a router config there is a lot of special characters like "" '' % $ () etc

and i need to treat everything as string

[visual walrus]

don't need to remove any system python, just go to the official python website. Download the sources and build with,

./configure --prefix=<custom_folder> --enable-optimizations
make
make test
make altinstall

[placid sparrow]

You have to edit the links though too

or maybe you don't? im not really sure

I prefer installing with apt, but you can also do that. Its up to personal prefrence

[visual walrus]

apt doesn't let you customize your installation as you do in windows.

[placid sparrow]

true

When I tried installing it from source pip kind of broke

[visual walrus]

yes, that pip thing is very annoying, for that you need to create aliases for different pip for different python versions, but prior to that including python paths to environment variables is necessary on ~/.bashrc or ~/.zshrc for mac

Anyone know how common it is for unix/linux distros to have a Music directory under the user?

A lot of times people have used my program they ended up having no idea where files ended up (though there is an option to set a path) and it defaults to os.path.expanduser('~') when unset.

Figured if an actual Music directory was common enough it might be worth simply creating it on those systems where it does not exist.

Idk if this belongs here but I tried installing both elementary/pop OS and both refused after applying every fix I could find on the internet to connect to any ipv4 website like reddit.com, websites that support ipv6 like google.com worke fine. I tried multiple browsers, diffrent DNS and network settings etc. When I used with the exact same network on the exact same device windows, it allowed me to connect to any site. Any ideas on how to fix this?

[ember quiver]

Are you getting a valid non-APIPA ipv4 address from your router? I'm not too familiar with those distros but this sounds like a DHCP problem. If you're not sure share the output of ip a.

[cinder crystal]

I'm curious
would using bash on OSX work for ethical hacking instead of downloading a linux OS?
it seems more convenient as well

[opaque ginkgo]

strictly speaking, bash is not necessary at all for ethical hacking

neither is linux

most tools work cross-platform

[cinder crystal]

I see

[lucid ridge]

definitely would, nothing magical about linux in that regard

unless they're telling you to use some distro that's got a bunch of security tools preinstalled

[opaque ginkgo]

you can always install those tools manually

most can be found in your distro package manager, or a language specific one like pip

for sure

Can't seem to find a single answer it's really frustrating

[ember quiver]

More context would be useful... What OS, what command did you enter, etc.? But you might try something like which sh or which bash

Hey @lethal sapphire!

It looks like you tried to attach file type(s) that we do not allow (.jfif). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

Feel free to ask in #community-meta if you think this is a mistake.

Why is this blocking:

    session.write("hi")

But this isnt:

with open("qcd_session", "w") as session:

i can write stuff successfully to /tmp without root

and yes i know the tempfile library exists but still curios

hey cyould test for me something ?

[candid dove]

How do I determine how much memory a certain program uses? In my case I want to know how much space PyCharm occupies, however using htop i get an output like this

so a lot of single pycharm processes, which take all the same amount of memory (10,4%). Is that the real number?

problem is, that I have some kind of memory leak. Some process is taking more and more memory over several hours until memory and swap are used up and my ubuntu just freezes. Im trying to find the cause, but these numbers dont help me or are not accurate

[tiny lava]

I'm not very sure on this but I believe that is indicating they are all using the same memory

like they are all sharing the same region in memory for all their data

[warped nimbus]

By default, htop shows individual threads of a process. To hide them press H.

[main olive]

@dusty furnace

i need some help

h.

H.

[candid dove]

yep, but i doubt there are 50+ processes each taking 10% of available memory

[warped nimbus]

So those are actual processes, not threads?

[candid dove]

standard output of htop just cut out the left side

each one got a PID

so yeah i guess

[warped nimbus]

Did you hide threads like I said?

[candid dove]

with H?

[warped nimbus]

Yes

[candid dove]

then 1 process remains

[warped nimbus]

Right, so it's just 1 process taking up 10%

[candid dove]

with the same amount of memory

[warped nimbus]

Everything else were just the threads of that process. It just shows the process's total memory usage for each thread I suppose.

[candid dove]

seems so. A bit confusing though

I'll probably should set up prometheus to monitor the usage

[warped nimbus]

Yeah that's why i always leave threads off in htop. It's there if you really need it, but I've never had a case where I cared about individual threads.

[visual walrus]

Which things can be monitored using prometheus?

[wise forge]

CPU, HDD, ram and fifty other parameters

Data would be recorded in time series database

So u could see how situation is changed in time

In week, in month and etc

[wise forge]

Plus technically there is an option for customisation that allows to track literally everything that fits the Rest API interface

Someone made for Django module

That exposes statistics happened in Django orm. Like how many times which model object was used

Prometheus has a lot of different data extractors

Compatible with different stuff

Linux OS, web servers like nginx, Frameworks like Django, databases like postgresql and etc

Full list is long

[visual walrus]

That means prometheus is used for way more stuffs.

[candid dove]

its more a tool to aggregate time series data

[visual walrus]

Htop can do this job probably.

[wise forge]

that was mentioned for Linux OS extractor

the difference in time series database to track it in time

and easy aggregation of data from multiple servers

[candid dove]

the data is provided by so called exporters

[visual walrus]

Can we also monitor website traffic with it?

[wise forge]

and later the data can be chained into other tools, like AlertManager, which would notify you automatically during some trigger, for example running out of space or high CPU load

[candid dove]

Graphana is often used to build graphical dashboards from prometheus data

[wise forge]

sure. You can monitor network traffic of the server
or you can monitor all actions of your web server

[visual walrus]

Okay.

I like to code in bash but is there any way, if there's any library we can do bash scripting in Python?

I mean I want to do that in Python what we do with bash, is there any way we can do that?

[candid dove]

I'd say yes

but we don't know what it is what you do

and how easy it is to do in Python

but most likely its much easier ...

[visual walrus]

Any third party library is needed or we can do without 3rd party libraries?

Any specific library is out there for this?

[candid dove]

I have absolutely no idea, what it is what you want to do

and even less, why you even think about doing it in Python

you would usually do it in python, because its much easier to do and better to mantain

If you just call a few shell commands, better keep it in bash

[formal schooner]

bash is a programming language unto itself

anything you can do in bash, you can do in python

however, they are two different programming languages and they have different strengths

for example, it's trivially easy to "pipe" programs together in bash, directly connecting the stdout of one program to the stdin of another, with minimal syntax (the | operator)

in python, it's not quite as simple to do with subprocess

also bash has some other builtins that might wrap syscalls and other libc functionality that python doesn't have a direct equivalent for

on the flipside, python is generally much much easier to build "sophisticated" applications with

[dense laurel]

Are there any packages that allow you to import terminal commands and run them as python objects? I have a terminal command nordvpn that has commands like nordvpn connect are there any python packages that would let me import nordvpn and then run commands on it like an object? like nordvpn.connect()

I could always make some kind of wrapper with subprocess or os.system and make an object that behaves that way but seeing if there was anything made already that could save me some time

[formal schooner]

probably not, because every program is a bit different in this respect

the pattern of command [options] subcommand [options] is pretty common but not at all standardized

[dense laurel]

Thanks, yeah just gonna build out an system call wrapper object then.

[formal schooner]

if anyone is interested, i cooked up a script that (heuristically) derives a python module name from a file name: https://gist.github.com/gwerbin/7d5705b5605c5b60a3c157efd0d19d26.

note: assumes you have zsh installed

example usage:

$ python-module-name -t ./tests ./tests/test_myapp/test*.py
test_myapp.test_healthcheck
test_myapp.test_interface
test_myapp.test_rules

i guess i could have written it in python, but zsh is too tempting

[warped nimbus]

Why did you need this

[formal schooner]

making it easier to invoke specific modules using unittest, so i can tab-complete them

could use this to write a custom completion function for unittest without having to actually invoke python (which would be slow)

[warped nimbus]

Oh, neat!

[burnt flax]

other step is writing a completion function which sends the thing and the thing

[weary atlas]

I'm not really sure that's the place for my question but.. let's try !
I'm currently struggling with CPU usage on a server - I'm wondering if there is any solution using Python to have a graph of the CPU usage for each hour, and if the % is higher than X, it would create a file with the list of the programs running with their % of cpu usage.. I'm probably searching in the wrong way and that's something doable with only Bash scripts.. Would love to get your opinion on this, thanks in advance 🙂

[warped nimbus]

I'm pretty sure psutil can provide you with CPU stats. Check that out

Seems doable with Python..You could use psutil and create an hourly cron job, or handle the scheduling all in Python if you really want to

[weary atlas]

Well I made some research for existing packages, it looks like a few things are already existing, I'll just need to make some python to list the programs running when the CPU usage is higher than X%

i'll check psutil then, thanks a lot 🙂

[astral cedar]

I feel like an idiot for not installing oh-my-zsh until now... I've been using zsh for over a year now and I just now got it installed yesterday . lmk if anyone has any suggested plugins

I try not to have too many cause I want the shell to be fast

So don't get carried away with adding plugins

I wanted to look into not even using oh my zsh at one point for even more speed but I couldn't be bothered. My shell feels okay where's it at currently.

[formal schooner]

you will feel even better when you realize you don't need it and uninstall it 😉

@warped nimbus I recommend Volta or FNM instead of NVM, much faster

N is also an option if you like more "interactive" TUI type applications

also check out fast-syntax-highlighting, much faster than zsh-syntax-highlighting https://github.com/zdharma-continuum/fast-syntax-highlighting

[warped nimbus]

if the time comes... I suppose that would be ultimate

[night maple]

what would be useful is what distro you're using
I am using Linux pop-os 5.15.8-76051508-generic #202112141040~1639505278~21.10~0ede46a
how you've installed it (your native package manager vs flatpak/snapd vs compiling from scratch)
what do you mean?

[proven trellis]

What was the process you followed to install PyCharm?

[night maple]

I tried the popshop,manually (following this instructions: https://www.jetbrains.com/pycharm/download/#section=linux), and then I tried through snap

yeah

Yeah that is correct.

[proven trellis]

What happens then?

You try step 3 and...

[night maple]

then when I tried to run pycharm.sh

then the console outputted: bash: pycharm.sh permission denied

[proven trellis]

So thats the script I mentioned. What is the output of ls -l pycharm.sh

[night maple]

hold on let me reinstall it

through that method so I can see that the output of that command

like I said I tried three ways

Yeah sorry for not being descriptive enough.

[night maple]

-r-----r-- 1 megaknight456 megaknight456 5751 Nov 30 03:16 pycharm.sh

[proven trellis]

Yeah, so the executable bit is not set. chmod 744 pycharm.sh

That will let you run the script

[night maple]

Thanks! that helped me

but now the second problem

when I try to configure the base interpreter as 3.10 in my project directory and try to pip install some packages. when I try to import the package I installed this error gets outputted```

[shrewd thicket]

how I change owner of a symlink?

[ember quiver]

That's a simple Google question, but the answer is chown -h

[ember quiver]

That link is saying that the package you are trying to install conflicts with a specific package/version that you have installed. So you might to to research and/or experiment to find out what other package is causing the problem.

Are you using a virtual environment? If not start there

[heavy mirage]

I'm not using a virtual environment yet

Just directly installing it under user

[heavy mirage]

It's happening for every package💀

Weird it works fine under sudo

[heavy mirage]

it seems to work fine tho ig il just use that

[ember quiver]

This should be avoided. Installing packages with pip in your main environment can cause conflicts. glad you found a workaround anyway though

how do I save the spacing format of a programs output text?

$ cat test-bad.py

the mypy output should look like this, pretty:

test-bad.py:1: error: Incompatible types in assignment (expression has type
"str", variable has type "int")
    a: int = "a"
             ^
Found 1 error in 1 file (checked 1 source file)

(QUOTES)

[warped nimbus]

Echo tends to have some confusing behaviour; I don't remember specifics. If you can assume printf is available on the system, try printf '%s' "$foo"

Or '%s\n' might be nicer in case you can't expect $foo to already have a trailing newline

Oh you wrote quotes. Yeah, that works too 🙃 Still IIRC echo does some weird shit sometimes

This is what i was thinking of https://unix.stackexchange.com/a/65819/

[formal schooner]

if you're using zsh, you can use the print builtin 🙂

also the main issue here is probably not issues with the echo command itself, but with forgetting to quote $foo

[formal schooner]

did you try quoting?

echo "$foo"

incidentally, in zsh you also don't need to defensively quote everything 😉

[warped nimbus]

Yes they did that's why they typed it caps afterwards

[formal schooner]

hm, i didn't understand that

[warped nimbus]

But... Posix compliance!

[warped nimbus]

Nor did I at first

Anyway as what I linked points out, posix echo shouldn't be used unless you know the string won't have escaped chars or dashes

Does anyone happen to have a suggestion on the "best" or most appropriate way to go about reading memory address values in unix based systems?

[viscid jungle]

Does anyone have any tricks or mnemonics for remembering where everything lives on Linux?

[viscid jungle]

Could you elaborate?

[south arrow]

hey guys, can somone explain this command? bash $ sudo netstat -tlpn | grep nginx

whats the | character, ive never understood it, is it and? or is it or

[wise forge]

| is syntax for command chaining / linux pipeline to redirect data flow

basically it means next thing...

perform sudo netstat -tlpm command, and data result out of it redirect into grep nginx

so basically we make a search, which strings contain nginx word in the output from netstat -tlpn

command chaining in linux allows also... to run commands in sequence
to run next command only if previous one succeded
to run commands in parallel / in background
probably something else

notably for data flow also used > to redirect output into always newly created file
echo 123 > 123.txt

creates file if it did not exist, and writes to the end of the file if it is already there

so...
echo "var1=123" >> build.env
echo "var2=456" >> build.env
could be useful to know for gitlab CI in order to transfer variables between jobs 😉

sorry I just saw the question

[pine osprey]

(i have a suspicion that what's going on for me is unix-based, forgive me if i'm in the wrong channel)

i've got a python script running on a raspberry pi that periodically writes data to a sqlite3 database. due to the purpose of this program, it'll stop when i unplug the pi from power, and i think i corrupted something in the database. i've screenshotted a ls of the database directory, and one of the db files has another one called -journal.

i guess i'm wondering what happened here?

[tulip dock]

@pine osprey: that's normal, it doesn't mean the database is corrupted

in fact if you delete it you might cause corruption

See https://sqlite.org/howtocorrupt.html#_deleting_a_hot_journal

[river apex]

if i add a watch to a log file with auditctl -w, will i receive audit log when the application is writing log

[pine osprey]

thanks for the info on this! i'm reading thru the documentation, but i'm still a little confused: how do i use the journal to get that transaction into my database?

[tulip dock]

SQLite will recover automatically from the journal when you open the database

If the transaction didn't commit it will not be recovered though, it will be discarded

[pine osprey]

so what's specifically in the -journal file, then? i thought that was an unprocessed transaction (from what i read in the documentation)

[tulip dock]

yep

[pine osprey]

and it makes the -journal file so that the .db file is uncorrupted, correct?

[tulip dock]

Yes but the way it recovers is by removing the part of the transaction that was applied

remember, SQLite is ACID: the A is for atomic, either a transaction commits in full, or it doesn't apply at all

Are you trying to recover part of a transaction that didn't commit?

[pine osprey]

i'm fairly new to sqlite and have some linux experience. at the moment, i'm trying to learn what's going on.

the second thing you said makes sense (per ACID), but then i'm left with one question:

it recovers is by removing the part of the transaction that was applied

if you said it's either committed in full, how can part of it be applied and that need to be fixed?

[tulip dock]

Well it's atomic thanks to the journal

[pine osprey]

oooooooooh

[tulip dock]

you never observe the partially-applied transaction, because SQLite will fix it before you can see it

[pine osprey]

gotcha, i get what you're saying now. thanks for the help with this!

[tulip dock]

https://sqlite.org/atomiccommit.html has all the low-level details

[pine osprey]

thanks again for all the info here, this helps me understand what's going on

how to ubuntu without breaking it

i'm a beginner by all means and when i boot i'm stuck at the `/dev/sdx clean, ... files, ... blocks message

ik that it's not an error but the issue is that it doesn't continue booting after that message

i'm fed up with searching on google and trying the various "solutions"

so i'm installing it again

it's frustrating, this has happened to be before and it's happened this time because i restarted the computer (i couldn't bloody find the Terminal in my apps)

i don't know if i'm doing something wrong and if i am, i don't know what it is

after installing i did literally nothing but modify the gui a bit and install some utilities (was about to install redis server when this all broke down)

i am by no means a slow learner, i catch onto stuff pretty quick and am able to make accurate educated guesses. but there's not much i can do with my knowledge when the whole thing shits on me with no discernible reason

thank you for coming to my ted talk, here's hoping that my 5th installation of ubuntu 20.04 lts doesn't fail me.

[gilded valve]

Ah I also experienced this earlier on in my UNIX usage. The terminal wouldn't appear because I setup the locale incorrectly. Once I fixed locale it appeared. Maybe that would help out?

dual booting windows and ubuntu rn :)

finally got that working properly

grub was being a bitch at first

[ember quiver]

I generally recommend running Linux in VMs nstead of dual booting. You're way less prone to these frustrating problems and it's much easier to recover when it does happen. WSL is also useful. Anything but dual boot, as it is usually a nightmare in my experience, and even just Linux on bare metal can be rough without the right hardware

If you've never done it before VirtualBox is probably easiest to start

Yeah Virtual box is easy to use..I moved away from dual boot too

But linux on bare metal also fine if you have a dedicated machine with supported hardware....Dual boot has complications

[stray prism]

Yeah grub can be a pain

[keen needle]

yeah

the easiest way to run on bare metal is to use a external hard drive

and just boot from it

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-375 ```
try this

these might be outdated. Not sure. All I know is that 700 series cards are now unsupported by nvidia

[gusty bramble]

Package 'nvidia-375' has no installation candidate

[carmine meadow]

weird

try sudo apt install nvidia-390

I used to use that driver

when using ubuntu

(i had old gpu)

https://download.nvidia.com/XFree86/Linux-x86_64/495.46/README/supportedchips.html

470.xx supports your card

[gusty bramble]

lol, my ubuntu had a problem with resolution when I installed cuda and rebooted the pc

just for no reason

LINUX IS BETTER THAN WINDOWS

y'all know that

[main olive]

every os has its downsides, one isn't inherently better than the other. the choice one makes also comes down to personal preference and various other factors

[lavish storm]

linux isn't a single OS lol it's not really comparable that way Parid

[main olive]

Depends on what you want to do

[slate crypt]

Windows is the best at giving your data to Microsoft 😉

It's also the best at running Nvidia drivers

[lavish storm]

i've never had a problem with nvidia drivers whether in Windows or in linux

same for CUDA and CUDNN thereof

[twin moat]

It's crazy how some people apparently don't experience any issues with some things that simply won't work for me. I get NVIDIA drivers to work under Linux but it's a pain each time. I hate it.

[wise forge]

i heard my friend mentioning recently that Pop OS (Ubuntu's fork) is having the least amount of problems to work with Nvidia drivers

[twin moat]

I've taken a look into PopOS a few months back, didn't try anything with ML though. Might try it out next time I have to set something up though.

[wise forge]

It could be working good for Nvidia probably because...
I heard that Pop OS is like distro intended for gaming.
And which gaming can be done without Nvidia?

[formal schooner]

i think it's very os-dependent and hardware-dependent

for example i have had exactly 0 issues with fedora 35 and the latest nvidia drivers, but i have an oem 1060

for all i know, a 1060 made by a different manufacturer might have a harder time

[weary orchid]

Does anybody have any experience with SCHED for unix/linux?

[formal schooner]

games run fine on amd. it's machine learning that really needs nvidia, because of cuda

[wise forge]

perhaps Pop OS has just drivers for all common providers, which would be more logical thing to have. ¯_(ツ)_/¯, i am not a Pop OS user though

[strange pagoda]

idk i have screen tearing with nvidia drivers rn

[fathom vale]

keep getting ModuleNotFoundError: No module named 'six'
for any apt command in ubunutu 20.04
six has been installed

[tall mason]

Did you pip install it?

[fathom vale]

yeah

[tall mason]

Hmm

Did you delete it and re install it?

[fathom vale]

yeah

[tall mason]

Oh. Hmm.

Idk. I'm out of ideas lol. Soz

[fathom vale]

lol nw

Hey, anyone feel like helping me de-break Python on Arch?

I messed up by updating all packages via pip . Now, even though I can, for instance, open the interpreter and import sys, my code that does the same can't find it

I've tried reinstalling the python package but it didn't fix anything... I'm at the point of trying a reinstall 😐

[formal schooner]

can you be more specific about what you did that broke everything?

it's possible that uninstalling python didn't uninstall the messed up packages fully. does pacman have an equivalent to the apt "purge" operation?

you might want to make sure you don't have any user-local packages, rm -rf ~/.local/lib/python*

i would try fully uninstalling python and python3, as well as any other python-related tools on your system like pyenv. then checking to make sure that all python-related stuff is gone, especially /usr/lib/python*

[lapis comet]

afaik it does, but I don't think that's a good idea because system dependencies

[lapis comet]

Simply updating all packages via pip

[formal schooner]

i see

note that this is why you should never use the system pip or python!

at least on linux you are usually prevented from messing anything up by requiring sudo

[lapis comet]

That's definitely a lesson learned, hahah 😔

[formal schooner]

did you do sudo pip install -U?

i am pretty sure pip explicitly yells at you if you run it as root

if you didn't do sudo then it's possible that this was a user install, which might mean that you can rm -rf ~/.local/lib/python* and be saved

[lapis comet]

I probably did, because there isn't even a python3.10 folder in ~/.local/lib/

[formal schooner]

you are in a bad spot here. did you ctrl+c in the middle or something?

can you tell pacman to uninstall a package without removing its dependents?

basically you have modified files that were supposed to be managed by your system's package manager (pacman), and now they are out of sync w/ pacman

when you said you reinstalled, how did you do it?

[thin berry]

why are people arguing that linux isnt an OS?

[formal schooner]

because the definition of an "operating system" is fuzzy

it's definitely a kernel. does a kernel constitute a complete operating system? the GNU project says no, it's not an operating system if you don't also have some kind of user-facing programs to interact with. so they like to call it "GNU/Linux" because it's "the GNU suite of user-space applications + the Linux kernel"

it's fuzzy because pretty much every other OS only exists as a "complete OS" and you can't really run the kernel separately

windows, mac, the various bsd's, even more obscure stuff like haiku

so arguably it's weird to call linux and OS because it is not a complete OS, but a core that you can build an OS on top of

the counter-argument is that no, a kernel is enough to be an OS on its own, because that is the part that "operates" the computer; everything else is just a program running on top

[thin berry]

so basically if anyone asks a linux-user what his OS is, he should say GNU?

[formal schooner]

meh

GNU isn't really an OS either

it was intended to be

[thin berry]

yeah, thats meh 100% 😄

[formal schooner]

but really it's just a suite of applications

i think most linux "distros" are OSes

so debian is an operating system

fedora is an operating system

they are both built on the GNU suite of applications and the Linux kernel

so i tend to say "linux-based OS"

or "gnu/linux-family of OSes"

nowadays gnu is probably less important than it used to be, but a lot of the core utilities on your computer are still literally GNU Coreutils

plus Gnu Compiler Collection (GCC) and GNU's implementation of libC are also pretty much standard everywhere

so i think it's fair that GNU at least gets some special shoutout

[thin berry]

like there is a thing i dont understand, so i have bootable PC, windows and linux on it. The boot-loader picks one of those two kernels in order to start the OS right?

like, when i turn on pc and when bios chip starts the boot-loader

so, if linux is a kernel, why wouldnt windows also be a kernel?

[formal schooner]

windows is a kernel, plus a bunch of other stuff

you can't run the windows kernel as a standalone thing, but it still exists, even if only as a concept

[thin berry]

right

soo, this looks like that the opinions are splitted if linux actually is or isnt OS, kinda looks like there are arguments for both things no?

[formal schooner]

right

[thin berry]

interesting tho, thx for the infos

[lapis comet]

just plain pacman -S

at this point, I'd be happy with a non-permanent solution such as pointing my scripts to the sys that can actually be imported, but I don't know how to do that

[formal schooner]

i'm not sure if there is even a sys.py, it might be a C module

[lapis comet]

it is a sys module hahah

tried printing a bunch of stuff verbose to see if I could understand how the import calls were made but I guess I'm too newbie for that

[formal schooner]

i'm a bit surprised that reinstalling didn't work

can you dump a list of packages that depend on python and reinstall them after?

even if you have chroot in through a live usb, you still don't have to repartition your drives, redo fstab, etc.

maybe just re-run pacstrap? i don't know the ins and outs of the arch system

[lapis comet]

No, IMO, because there are even Linux distros that aren't based on the GNU toolset (e.g. Void, Alpine)

[formal schooner]

(void still uses gnu programs all over the place 😉 )

there is a musl version of void though i think

[lapis comet]

I thought the musl version was the default nowadays?

[formal schooner]

i'm not sure. i recently installed void on my thinkpad and i am pretty sure i chose the glibc version because i was scared of musl being incompatible with everything

[lapis comet]

I thought of doing that... but I'm afraid that'll break more things XD

[formal schooner]

well this is why pip now warns you loudly about not using sudo 😛

[lapis comet]

Yeah, that was the first time I went trigger happy with my commands 😦
disclaimer: been using Linux only since last April

[formal schooner]

one reason why you can't just rm -rf /usr/lib/python* and reinstall is that this will also remove any other python-based deps that were installed

oh.. do you have both python2 and python3 on your system?

[formal schooner]

been using Linux only since last April
good, you made it a whole year without breaking your system!

the nice thing about arch is that it's actually a relatively "thin" system - few layers of configuration and packages that are mostly the same as the "stock"/upstream versions means it's easier to un-fuck than some other systems

that's really the main appeal of arch. rolling release is bleh, but if you want a system that is highly configurable and mostly gets out of your way while also providing good defaults, arch is great

[lapis comet]

yep, though python2 is only there by dependency

[formal schooner]

is it possible that you ran pip install with pip2?

[thin berry]

why would you use pip when you have sudo?

[lapis comet]

Nah, pip2 isn't even installed

[formal schooner]

sudo and pip are entirely different things. pip is a package manager for python. sudo is a program that lets you run a command as another user

"su" is the "switch user" program, "sudo" is the "switch user and do something as that user" program

the usual usage of sudo is to run as root

[thin berry]

ah yeah, pip can be used in python terminal

[lapis comet]

what's funnier is that I tried upgrading stuff via pip due to the muscle memory from doing that in Windows
