unix

[main olive]

i don't even have the file 😦

[formal schooner]

maybe this is a bug in the aur package then

[main olive]

found something on stackoverflow
they said i have to run sudo ln -s /usr/lib/virtualbox/postinst-common.sh /sbin/vboxconfig

[formal schooner]

huh. i wonder why that's not in the aur package already. i would look over that shell script carefully before running it

[main olive]

i am gonna change my mirror and retry everything

[primal blaze]

Looking for good terminal options in Ubuntu?

[green spear]

@primal blaze I use Konsole.

It is the KDE default and very good.

[ember quiver]

What about the default one makes you want something different?

[primal blaze]

I install terminator and using it

[wise forge]

@primal blaze agreed. Installing Kubuntu and enjoying defaults is the best xD

whole GUI is nicely configured by default

[primal blaze]

Any apps would you like to recommend for daily ease of use? @wise forge

@wise forge @ember quiver For Ubuntu

How can I speed up my Ubuntu?

Any Suggestions

[wise forge]

Totally depends on your needs and job role

[wise forge]

U can use zram to increase Ram memory, usually very often needed thing when u have multiple browser tabs and IDE xD

https://www.maketecheasier.com/configure-zram-ubuntu/

[wise forge]

i am also fan of enabling LUKS file encryption during its installation. Feels more secure when your info in storage is fully protected from theft
Just one checkbox to click during OS installation for that

[wise forge]

anyway, for every day usage for me, it is just messengers: Skype, Discord, Telegram, Slack, Zoom
google chrome for browser
qbittorrent to download torrents xD
for virtualization: virt-manager + vagrant
for containers: docker+docker-compose
for kubernetes: kubectl+helm
for infra provisioning: terraform + aws cli
for ide: vscode/vscodium
for vsc: git cli + experimented to try finding GUI for that, but so far using just vscode Git integration + vscode Git lens
for documenting/accounting: git-crypt to protect git repository with encryption, sqlitebrowser for database, pdftk + PDF chain as GUI for pdf mergins, ImageMagick to resize jpegs + scanning programs for my compact EPSON DS-310 + typora for markdown xD
poetry for python very nice package management
wireguard for VPNs when necessary
vlc for video watching
postman sometimes useful from times to times to make requests manually xD
and of course i install latest pythons to my system and just make alias to .bashrc

alias python='python3.10'
alias python3='python3.10'

this is safest way to install newer pythons i think (if to skip usage of poetry)

[lavish storm]

Pyenv

[wise forge]

how does it work? what it gives as end result? and is it able to do that without breaking Ubuntu which depends on default installed python for most of its programs?

probably i should try it safely in container/virt machine

[lavish storm]

It installs a version of python of your selection, and localises it to a project or a folder. It doesn’t interfere with your system python

So installing multiple versions of python for different projects requiring different versions of python is possible

[wise forge]

does it make correct python of necessary version automatically enabled for the right folder?

oh yes, i see

nice feature

[lavish storm]

😄

[wise forge]

although a bit confusing one 🤔

and dangerous

it allows changing global python too xD

if u will do it, u will kill Ubuntu

probably

unless it makes some safeguards to disginguish System / Global python as it meantions in docs

[lavish storm]

Well that can very well “kill” any other distro

Though the problem seems most pronounced with Ubuntu for some reason

[wise forge]

oh yeah it can change system python too xD this will kill for sure. Or may be it can't

ergh. dangerous xD

alias to override user python is safer

+using poetries ;b

[lavish storm]

Whatever works

😄👍

[wise forge]

i think there is kind of no point to use it considering that python is backward compatible

for global usage it is enough just upgrading forward ;b

for project wise -> it is enough to use poetry if it has any libraries, or any other package manager capable to set python version. No point to have dedicated program to change python version only

[lavish storm]

We are blessed to have many choices, though that also may be a curse

I can’t see why one can’t use both pyenv and poetry for multiple python projects

[wise forge]

sure. pyenv is more like direct alternative to having alias in .bashrc
poetry is additional tool going fine with both choices

[lavish storm]

pyenv is more like direct alternative to having alias in .bashrc
I do not agree with this statement

[wise forge]

let me fix it then:
it is alternative to my alias in .bashrc, which is more feature rich and developed to deal with it in a dynamic way

in the end pyenv is not dealing with package management, which is first concern of pipenv/poetry level of tools. That's why it limits it to alternative tool category

[dapper musk]

alias works only in interactive shell tho. if you for example made start.sh calling python it would refer to “normal” i

it is more similar to PATH overwrite

[deep bluff]

so im using debian 11 and i ran command python3 --version and looks like there is python installed automatically Python 3.9.2 but 3.9 and i want to upgrade to 3.10 how can i do it im not really into linux

[fickle granite]

heh, not a bad place to ask

[wise forge]

we just described two methods above u for that

using alias in .bashrc (will work only for interactive terminal of current user)
and more reliably pyenv which does magic through PATH

first method assume u will install python 3.10 like

sudo apt update
sudo apt install python3.10
sudo apt install python3.10-venv

and then add into .bashrc of user

alias python='python3.10'
alias python3='python3.10'

pyenv method should be same in first steps except replacing .bashrc alias with its own commands pyenv global 3.10 or something like that
(pyenv way is supposed to be better in terms of changing python also automatically for pip and etc, plus for non interactive script runs. Plus pyenv adds more feature options regarding that)

[wise forge]

⚠️ do not uninstall 3.9.2 python. it is system python and without it system will crash

https://stackoverflow.com/questions/1615877/why-aliases-in-a-non-interactive-bash-shell-do-not-work apperently it is possible using alias for non interactive shell too though

[wise forge]

did u run sudo apt update ?

[deep bluff]

yes

[wise forge]

oh yes, forgot, u need to add it with more commands a bit

[deep bluff]

?

[wise forge]

https://computingforgeeks.com/how-to-install-python-on-ubuntu-linux-system/

sudo apt install software-properties-common -y
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update

only after that it will become available

[deep bluff]

its still not found

E: The repository 'http://ppa.launchpad.net/deadsnakes/ppa/ubuntu lunar Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

[fickle granite]

not sure you can use Ubuntu ppas on Debian 😐

[wise forge]

oh yeah.. forgot that little detail that he has debian xD

find same instruction for debian

or use instruction how to build from sources from link above

[fickle granite]

@deep bluffif you're interested, I've cobbled together something that works

[deep bluff]

what is it

[fickle granite]

buncha instructions

hold on

as root

    # apt build-dep python3
    # apt build-dep python3-openssl
    # apt build-dep python3-pip
    # apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev

as non-root

   $  wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tgz
   $  tar zxf Python-3.11.0.tgz
   $  cd Python-3.11.0/
   $  ./configure && make
   $  ./python -m ensurepip
   $  ./python -m pip install --upgrade pip

those are, of course, very terse, and I might have left out something important

also it's 3.11 not 3.10

also it just leaves the executable in ~/Python-3.11.0/python instead of installing it

but it's usable

[formal schooner]

why not just use pyenv?

it automates all that junk for you

well, it won't download dependencies for you. but it handles fetching source tarballs, building, and installing

[fickle granite]

jonaton must have spent an hour with OP trying to get pyenv working

I think it finally did, but it wasn't easy

[formal schooner]

i see. i've never had trouble getting it to work

[fickle granite]

I've never tried very hard, tbh

[formal schooner]

it's just a collection of shell scripts, so as long as your system isn't already in some badly messed up state, you can just install it following the instructions and/or from a package manager and it should work fine

i personally don't like the default location of ~/.pyenv so i have export PYENV_ROOT=$HOME/.local/opt/pyenv; mkdir -p $PYENV_ROOT in my shell config

and you can set compilation flags easily too

PYTHON_CFLAGS='-march=native' \
PYTHON_CONFIGURE_OPTS='--enable-optimizations --with-lto' \
pyenv install 3.10:latest

[fickle granite]

ok that was indeed a ton easier

[formal schooner]

fwiw the configure && make && make install stuff is usually pretty easy too

as chaotic and ridiculous as autotools is from a developer perspective, from a user perspective it's pretty damn magical and easy, if the developer set things up correctly

[fickle granite]

heh

users should not be anywhere near autotools

I honestly think autotools have outlived their usefulness.

There are only a few platforms:

• Windows
• Linux
• MacOS

just write bespoke stuff for each, and be done with it

[formal schooner]

./configure && make && make install is still pretty much standard on mac and linux though. what's the alternative? meson? cmake?

[fickle granite]

nobody cares about SunOS any more

iirc this is what git does

[formal schooner]

what, have a completely separate build process on each platform?

[fickle granite]

yes.

there are only three platforms.

[formal schooner]

the problem is that even on the same platform, setups vary wildly

[fickle granite]

MacOS == brew

problem solved 🙂

[formal schooner]

and macports and building from source and....

[fickle granite]

to a first approximation, nobody uses macports.

[formal schooner]

even if you never build anything from source by hand, package managers differ a lot more than you are giving them credit for

[fickle granite]

right, target one package manager per platform.

[formal schooner]

macports is honestly awesome and is surprisingly well-maintained

[fickle granite]

🤷

this is all academic; I don't run any open source projects.

[formal schooner]

i don't understand why it didn't catch on, maybe bad marketing and lack of a simple website & installer (which homebrew did/does have)

[fickle granite]

popularity is only vaguely correlated with quality.

[formal schooner]

yeah it's just an interesting case study. i learned about homebrew first in ~2014 and never heard of macports until after i started using brew, even though brew came later

some kind of memetic effect

anyway, there is a lot of legitimate need to support a variety of build configurations

[fickle granite]

maaaaaayyyyybbeeeee.

iirc, openbsd had an interesting idea:

[formal schooner]

for one thing, ./configure scripts do a lot of detecting of compiler features. that's something you simply can't control

[fickle granite]

the openbsd maintainers, themselves, only maintained the stuff that was specific to openbsd

[formal schooner]

and the "everyone has a different setup" scenario is important when looking for dependent libraries on the system (unless you explicitly invoke pkg-config to set CPPFLAGS and LDFLAGS)

[fickle granite]

they had separate packages for the "portable" versions of things

[formal schooner]

that works because they control the OS all the way down to the kernel

the "portable" versions undoubtedly use some kind of build configuration, even if it's not autotools

[fickle granite]

yep. Can't remember what it was though

but my point is: they kept that complexity out of the non-portable version, which seems like an OK compromise

the people who need the complexity pay the cost; those who don't, don't.

[formal schooner]

i guess, but then you are maintaining two entirely different build systems

[fickle granite]

yep

life is nothing but a buncha trafeoffs

[formal schooner]

that seems worse for most projects than having one flexible build system that works with minimal configuration in common cases

openbsd is not a typical project

[fickle granite]

💯

ok, pyenv just made my life better:
A few days ago I'd installed python3.11 via brew, and it didn't work well in Emacs (something about readline). So I just tried using the pyenv version, and it works fine 😐

[tepid drift]

does anyone know what cp -a do

[fickle granite]

I bet if you typed cp --help you'd find out

[tepid drift]

that's why I'm hear

[fickle granite]

what did it say?

[fickle granite]

yep, mine too

[tepid drift]

what a coincidence

[fickle granite]

ok so you're saying you don't understand that

I didn't realize that

[tepid drift]

yea that what I'm saying

[fickle granite]

it copies recursively, and leaves the timestamps alone

if you're on Linux you can do man cp for a more-detailed explanation

[tepid drift]

so it won't change the timestamps

[fickle granite]

(on MacOS, unfortunately, that brings up docs for a different version of cp 🤬 )

[fickle granite]

I think not. Try it and see.

[tepid drift]

wait there is no cp in MacOS?

[fickle granite]

no, I'm saying (at least on my Mac) there are two and they're different

there's the one that comes with the OS, and then there's the one that comes with "brew"

[tepid drift]

I didn't figure it out

could you explain this paragraph : Copy the files and directories and all of their attributes, including ownerships and permissions. Normally, copies take on the default attributes of the user performing the copy

[fickle granite]

this is what cp normally does

% ll perfcount/perfcount.7889.natd
-rw-r--r-- 1 root 1.6M Oct 30 08:25 perfcount/perfcount.7889.natd

% cp perfcount/perfcount.7889.natd wooly

% ll wooly
-rw-r--r-- 1 offby1 1.6M Oct 30 12:08 wooly
%```

see how the original is owned by root, but the copy is owned by me?

[arctic coral]

Not sure if this is relevant here, but how can I resize my / partition ?

The free space before is greyed out

[dapper musk]

you cannot do it with ext4 it only expands "forwards"

and it cannot be live

you can in theory copy all the data from it. then make new ext4 partition and copy it back. and to make it bootable again you would need to do stuff with grub(or whatever bootloader you are using)

[dapper musk]

it does't

or rather it only does when there is't file here already

[fickle granite]

fine, you answer the guy's quesition, then

[dapper musk]

-a ensures that it is the case

it also copies extended arguments

[formal schooner]

can you work around this using LVM somehow?

[dapper musk]

touch 123
chmod 700 123
cp 123 1234
ls -l 1234
----------. ....
# Permissions are the same
rm 1234
touch 1234
cp 123 1234
ls -l 1234
-rw-r--r-- ....
# Permissions are diffrent
touch 123
chmod 700 123
cp -a 123 1234
ls -l 1234
----------. ....
# Permissions are the same
rm 1234
touch 1234
cp -a 123 1234
ls -l 1234
----------. ....
# Permissions are the same
setfacl -m u:test:000 123
cp 123 12345
getfacl 123
getfacl 12345
# Extended attributes are diffrent
cp -a 123 12345
getfacl 123
getfacl 12345
# Extended attributes are the same

it also applies to other things. basicly it ensures that files are identical not just in content

[arctic coral]

boot loader eh ? mna l boot partition bta3y m4 lmso

also ana bs m7tag a3rf a3ml ftsab file s7

[dapper musk]

maybe? you can relocate logical volume and then extend it as far as ik

[arctic coral]

w 5ayf nek m3rf4 a3mlo

[dapper musk]

what?

[arctic coral]

y3ni ana grub 3la nvme0n1p8

dh mlosh ay d3wa bay 7aga

bs ana 3awz a3ml el 70G root partition b3d l 29.5G

b3d kda a3ml extend

bs lazm a3ml

"fstab" sleem 34an lma aft7 l computer

y3ml mount s7

[formal schooner]

that's what I was thinking, but maybe you can't just relocate the filesystem back to the beginning of the LVM volume, that might be too magical

how to open py and pyw file in ubuntu? when i click the file in windows, it open the program and when i click the file in ubuntu it just opens the text as it was a text file

[ember quiver]

Not sure but I think you might just need to change the permissions to make it executable. There are some other ideas here but not sure if they're current https://stackoverflow.com/questions/11848650/how-to-run-python-script-with-one-icon-click

[green lichen]

thanks

[fallow tusk]

I found this: https://askubuntu.com/a/1379730 using a .desktop file…

[wise forge]

@green lichen the most correct way, adding like at the top of file

#!/usr/bin/env python3

P.S. This verision of shebang is the most correct one to catch any python3 automatically

and making sure file has right permissions for execution.

chmod +x your_file_name

makes scripts easily executed in shell too

./your_script_name

[green lichen]

i know there is something with changing the properties and changing the default program but i dont know what program to associate the file with

[ember quiver]

I believe Darkwind has given you the steps above. No need to change file assocations

[green lichen]

ok thanks guys didn't helped but thanks

wayland's prob better, it's just a lot of kwin scripts were made for x11

have u tried gentoo?

[humble falcon]

Nah, I value my cpu too much lol

[main olive]

i am new to linux, but tried to set up gentoo 5 times

people say i have to do linux for 1 year to do gentoo

💀 idk why i even wanted to swtich to gentoo

[fickle granite]

me neither

if i were going to run Linux at home, it'd be Ubuntu

not gonna waste my time with anything else

[main olive]

pop_OS?

[humble falcon]

Gentoo is more of a niche thing tbh

[main olive]

yeah, i don't think i am ever gonna try it out actually

was in the distro-hopping phase of my linux journey that week

[humble falcon]

Afaik it's mostly for people who don't trust anyone else, even to compile things lol

[main olive]

i can't decide
arch or debian

or fedora

idk what i am tryping sorry for the errors

feeling drowsy

[humble falcon]

I stopped distro hopping when I realized that all distros are pretty much the same. Only difference is the release models (stable vs rolling), install/setup, package manager/repos, and the documentation and community. Other than that, any distro can do what any other can, with some tweaking

I decided I wanted a rolling release distro with a lot of documentation and not a lot of stuff preinstalled, and arch fit pretty well for me there

[main olive]

i've tried arch and debian, i like both package managers, documentations, and they are both relatively light, can't decide what to use

arch works fine but there's this lack of "how to install this thing" <- future me will cringe at this message

[humble falcon]

Main difference would be the release models then. Do you prefer having newer software but updating a lot and potentially having stuff break, or do you prefer more outdated stuff, but less likely to break, less updates, but needing to reinstall every year or so

[main olive]

arch works fine for me

yeah

why is debian's bashrc so flooded

[humble falcon]

Yea personally I've never had anything break on arch (after I got everything set up). Main reason being that the developers of software should have the same exact version of every package I have

[main olive]

man i think i need to go to sleep

[humble falcon]

Alr, gn

[worthy briar]

Do we have any nixos users here?

[fickle granite]

played with it once? Long ago? Don't remember anything about it?

[worthy briar]

I have a question about it

why does it exist

[fickle granite]

I think the idea is: specify every bit of the OS, down to the bit level

so that you can be certain you've got the same bits as someone else

[worthy briar]

Hmmm

[fickle granite]

also something about allowing multiple versions of any package simultaneously

interesting academic idea which never took off for whatever reason

maybe the problem it's solving isn't that important; maybe it's too hard to use; 🤷

[worthy briar]

Hmm

I was thinking about giving it a shot

Do you think it's really dead?

[fickle granite]

well, the maintainers might be still plugging away at it

but to a first approximation, nobody uses it

[worthy briar]

Hmm that sucks

I really liked the unified config thingy they promise

I was like you can do that? That's awesome

[fickle granite]

well play with it, maybe you'll fall in love with it, and work 50 hours a week improving it, and making it popular

[worthy briar]

😄

That doesn't sound like me

I would love to just take the config part

but stay with active distros

I don't think there is anything like that 😦

[fickle granite]

fwiw I think nixos keeps their packages current

srsly, try it

just because not many people use it, doesn't mean it won't solve your problem.

It's unlikely to, but you know more about your problem than I do 🙂

[green lichen]

can someone help me how to execute a py or a pyw file in ubuntu? i know i need to change its prorpiertreies and 'open with' but i dont know what app to associate it to

[tranquil coyote]

open a terminal and run:

python3 /path/to/file

[main olive]

what does : do in fish/bash
when i type : in my terminal it does nothing and returns no error

[main olive]

in my terminal it's kinda weird
when i type python it executes the code in v3.10.8
when i type python3 it does it in v3.11.0

probably has something to do with pyenv

xonsh shell is a pyhton powered shell

https://xon.sh/ really cool

[main olive]

fish sucks

[green lichen]

i tried

(duclk isn't my middle name ok)

[tranquil coyote]

the file was executed correctly, you need to install tkinter though

[green lichen]

but cant i execute it double clicking like in windows?

[tranquil coyote]

you should be able to set the python3 command as an application

[green lichen]

how

i cant

i might just install python again on ubuntu

[tranquil coyote]

sorry, I don't have access to an Ubuntu machine right now, maybe this can help:
https://stackoverflow.com/a/304896

[slate crypt]

You usually don't double click py files. You should use pyinstaller and a desktop file instead.

or just a .desktop file

https://www.maketecheasier.com/create-desktop-file-linux/

[green lichen]

nvm i give up of coding in linux

wait cant i make it an .exe file and run it on zorin os?

[wise forge]

u mean binary file, with which kind of application?

[lavish storm]

Well, you're trying to use a drill for a hammer's job and complaining about it

If you don't want to use linux then don't use it. But you can always come back free of charge 🙂

[mortal ginkgo]

Any tips/sites where I can find some reference code in Python 3 to re engineer some python2 scripts we run to check CPU/Mem usage and another for file system usage alerts? Been hard to find and 2to3 package can break on some systems. Thanks

Too new to Python to figure out the syntactic differences

[formal schooner]

it's probably still not a bad idea to start with 2to3. feel free to ask if something specific breaks

however you should probably read https://docs.python.org/3/howto/pyporting.html

and that doc links to this one: http://python3porting.com/

[mortal ginkgo]

So 2to3 has been solid as far as I can tell but recently it broke on a system we couldn’t afford it to break on

[formal schooner]

well you'd have to test it of course

[mortal ginkgo]

Yea its broken on one out of 50 RHEL 8 servers AFAIK but thats the point, if the script doesn’t email us as it has done solidly for 5 years we won’t know and are too swamped to check 50-100 servers for other surprises, wanted to update code snippets to comply with python 3 formatting

Will check out your links

🙏 thank you

[formal schooner]

it's very likely not a formatting issue if it breaks on 1/50 servers. the biggest issue you are likely to encounter is related to strings. python 2 strings were essentially raw byte sequences. python 3 strings are unicode code point sequences. if your python 2 code was not already using u"" unicode strings, then you might want to start by using byte strings b"" in the python 3 code, which are equivalent to the non-unicode python 2 strings (plain "").

[mortal ginkgo]

Yea, i don’t think the script broke, i think 2to3 wasn’t currently installed on there

[formal schooner]

e.g. if you have a file on the bad system that isn't valid according to sys.getfilesystemencoding(), then you will get an exception when trying to convert that filename to a string

oh... well that's not 2to3's fault!

[mortal ginkgo]

Worked fine when I reinstalled it. But figured it would be worth the effort to change 100 lines of code or so

[formal schooner]

for 100 lines of code it shouldn't be too hard to run 2to3 and ask somewhere online (here, perhaps? 🙂) if it breaks

[mortal ginkgo]

That’s true, I’m new to this server, but glad I found it. Really interested in rewriting some shell scripts into portable python scripts

But I’m full time on a small team, our hours are efficient and we are Ops so it’s a lot of fires to put out

Like our 8-9 day long Red Hat Satellite upgrade thanks to background processes migrating ~200GBs of data overnight 3-4 times etc

[formal schooner]

and this is why i'm not in devops

[green lichen]

its because i want to it be universal and if i put this specific code at my code it will only run on linux

[ember quiver]

Your code can have different logic based on the OS it's running on

[green lichen]

so i cant make it universal?

[ember quiver]

What are you trying to do exactly?

[green lichen]

make it universal i mean make it executable from linux OSs and windows

i wanted to know that what is ros and gazebo and how both related to it?

[main olive]

when you do man date

it gives u some options, right?

so how to forexample use %d ?

instead of date -I i wanna do the %d%m%y format for the context

[lavish storm]

date +%d?

you can just add other %? as well, for example --

$ date +%m%d%Y
11072022

one can also insert other chars for separation, like - and _

$ date +%m_%d
11_07

if you have GNU date then %F is also a nice shortcut that formats it as %Y-%m-%d

I'm unsure of BSD date, because i don't have the means to test it

Can someone help me out movin 7560 xml files to another directory in random order

I'm trying to use this command

!ls /content/gdrive/MyDrive/CustomTF2/data/annotations/* | sort -R | head -210 | xargs -I{} mv {} test_labels/ # 1

But i get this error message

/bin/bash: /bin/ls: Argument list too long

FYI my ARG_MAX it's

2097152

[formal schooner]

why not use rsync?

rsync -av /content/gdrive/MyDrive/CustomTF2/data/annotations/ test_labels/

looping over ls output is fragile

ARG_MAX is the max number of bytes, not the max number of args

[lavish storm]

i'm unsure what they actually mean by

in random order

[formal schooner]

that too

i mean, sort -R does it. but what's the point of moving them in any particular order at all?

[lavish storm]

precisely

[summer trail]

and it's the max number of bytes for the arguments and the environment variables table combined

[formal schooner]

oh, even worse

[summer trail]

yeah, it's not too unusual to see people fill up their environment variables with such long strings that exec's with reasonable numbers of arguments fail

Anyone use pyenv on macos?
I have a issue where the stuff i install in venv
also get installed in global env in pyenv

[fickle granite]

I used it once. I doubt it has anything to do with the behavior of venv though

[main olive]

Often, you use Python to “wrap” other scripts or Unix commands.

[formal schooner]

I have a issue where the stuff i install in venv
also get installed in global env in pyenv

that should not happen. either:

1. you installed it globally instead of in the pyenv (forgot to activate a version?)

2. your current pyenv version is system, which is just an alias for the system python

3. you used pip install --user, which always installs to the same directory in your user dir. you do not necessarily need --user when using pyenv, and arguably should not use it to avoid conflicts with other python installations. you should still use venv or pyenv-virtualenv on a per-project basis.

[astral talon]

Hi everyone, im working on a python script that needs to fetch environment variables. Iam facing a particular problem, the script checks for certain environment variables, if they dont exist, the user is asked to add them and rerun the script. When i add said variables, and rerun the script, the script doesnt detect the newly added environment variables. For context, iam running the script in a zsh terminal on a Mac

Iam also using os.eviron.get() to fetch the variables

[fickle granite]

you're not adding them properly

you'll have to post a transcript of your terminal session

[astral talon]

export PKG_CONFIG_PATH="some-path"

When i echo this, it prints it out in the terminal

[fickle granite]

I don't know what you mean by "when I echo this"

that's not a complete transcript; how are you running your program?

[astral talon]

echo $PKG_CONFIG_PATH

This is how i test that the variable was added properly

Python3 "path-to-script" is how i run the program, i can post a terminal transcript tomorrow but i just wanted to confirm that the terminal doesnt need to be restarted

[fickle granite]

that's actually not a good test, but it's probably ok

when i try to recreate it now
it doesnt have the issue

thanks anyways

im not sure if you can help with this problem
where do i point for the base interpreter
im not sure if that is the system python

this is pycharm btw

[astral talon]

I must be doing something wrong then, im running the terminal from within vscode, not sure if that has an effect on anything

[fickle granite]

@astral talon it would have an effect. Environment variables only affect the process they're set in, and (usually) children of that process. But if you set the variable in a vscode terminal, and then use vscode to run the program, the terminal is actually a child of vscode, and your running program is as well: so the terminal is trying to affect its sibling, not its child; and that doesn't work.

vscode has a place where you can give it environment variables to set when running your program. I think it's called a "run configuration".

Hello, is there anyone here that knows a lot about sockets? (specifically RAW_SOCKETS)
I'm trying to send a SYN packet (that I created) and receive the answer. It works when I do it synchronously but when I run the function in multiple threads it starts doing weird things (answers that have nothing in common) even tho it looks ok in wireshark

[formal schooner]

the "base" interpreter is the system python that you intend to use to create the venv. ideally you'd use pyenv to install an exact version, but /usr/bin/python3 is totally fine for basic work

[astral talon]

Thank you for this clarification, that makes a lot of sense now.

[strong forum]

Shouldn't it be pyenv global env?

Cuz i often heard to not use system python

[lavish wasp]

if I make this call in command line

cb | py project.py

Is there a way to get the contents from cb in my Python script? Like for example through sys.argv?

Thank you in advance!

[fickle granite]

read from sys.stdin

[lavish wasp]

ok thank you!

[lavish wasp]

Pardon, if I read from sys.stdin, what would that look like?

This was my output, but I'm not entirely sure how to read from it...
sys.stdin: <_io.TextIOWrapper name='<stdin>' mode='r' encoding='cp1252'>

[fickle granite]

that would depend entirely on the output from cb

I have no idea what cb is, nor what it outputs

so I cannot tell you what it would look like

[lavish wasp]

It's just text

I can post here one second.

[fickle granite]

er, then, I guess that's what reading from sys.stdin would return?

[lavish wasp]

oh wow lol

[fickle granite]

are you asking how to read from sys.stdin?

[lavish wasp]

Yes, just so that I can extract that whole text piece, and parse it. That's what my script is doing, but I'm reading that same text from other text files, however I want to be able to do it just from the clipboard.

[fickle granite]

import sys

for line in sys.stdin:
    print(f"I gotcher line right here {line=}")

# cat /etc/passwd | ~/.pyenv/versions/3.11.0rc2/bin/python3 unix.py
# I gotcher line right here line='##\n'
# I gotcher line right here line='# User Database\n'
# I gotcher line right here line='# \n'
# I gotcher line right here line='# Note that this file is consulted directly only when the system is running\n'
# I gotcher line right here line='# in single-user mode.  At other times this information is provided by\n'
# I gotcher line right here line='# Open Directory.\n'

[lavish wasp]

Ah, my senior gave me this haha, but I missed it.

sys.stdout.write(repr(sys.stdin.read()))

I can just set that to a variable, and it comes out as one huge string.

[fickle granite]

indeed

[formal schooner]

it's ok to use the system python if you are installing packages inside a venv. however the venv will break and need to be re-created when the system python is updated to a new version.

but you should never use sudo to install packages with the system python. that will install packages into the system package directory and can/will break not just python but your entire system (a surprising amount of programs on a typical linux system are written in python)

[strong forum]

got it
so if i want to use the python version in pyenv
do i need to point to different base interepter?

[humble falcon]

Any version installed with pyenv should be fine, also why are you tryna download a yt stream lol

[strong forum]

thats not what im asking
so in the venv it says im using python 3.11
but pycharm says im using python 3.9

also im not trying to download yt stream

[formal schooner]

yes. in the shell, activate the pyenv version that you want to use in pycharm and run pyenv which python. use that output as the interpreter in pycharm

note that a venv is not pyenv

pyenv manages python versions. venv is an isolated set of installed packages.

[strong forum]

The thing confuse me is base interpreter in pycharm

Ig ill just use the pyenv which path for that

[formal schooner]

the "base interpreter" is only for venvs

The workflow is: install the version of pyenv that you want, activate it, use it to create a virtual environment.

then point pycharm to that virtual environment. the base interpreter should be updated accordingly, but if not, the base interpreter will be the version of pyenv you used to create the environment

[strong forum]

according to this ss it is not happenning
venv is using diff python version(whihc is in pyenv)
and pycharm saying im using python 3.9 which is system pythob version

[wise forge]

not knowing I3, but u can try it with remote desktop right out of docker container!
https://docs.linuxserver.io/images/docker-rdesktop
https://hub.docker.com/r/linuxserver/rdesktop

Although KDE is not very good working within containers u need to forward your video device for it to work correctly i think

[main olive]

ok

[wise forge]

i like KDE very much though, definitely recommending.

Kubuntu is awesome

What's more to desire regarding GUI

[ember quiver]

I love i3, have never tried it with KDE

[formal schooner]

+1 for KDE, i haven't used it with an alternative window manager but the built-in window management features are good enough for what i'd want

[amber tree]

i3 alone is cool but dwm even better

[fallow tusk]

I've been using qtile recently. Xmonad previously, hoping to learn some Haskell by stealth, but it didn't happen! What are the advantages of dwm over i3/qtile/xmonad?

speaking of monad... i am a massive fan of kmonad, but that's for remapping keyboard and not a window manager

It's a automatic tilling window manager and is made in C

C is cool

👍

I use arch btw

I'd try xmonad if not haskell tbh

[opaque ginkgo]

lmao

average c/cpp elitist

[formal schooner]

one way is ls -ld /var/www/html/wordpress/

[dapper musk]

rwx = 7
r-x = 5 = 7 - 2 = rwx - w
r-x = 5 = 7 - 2 = rwx - w

ie 755

x = 1 w = 2 r = 4

[wise forge]

@dapper musk how about actually using letters instead of symbols. They are way more easier to remember instead of doing math
chmod -R u=rwx,g=rx,o=rx /var/www/html/wordpress/

+benefit of having readable commands what they actually do! (yay to clean code)

and if ever challenged to remember
writing chmod --help and finding regex of how to do it
Each MODE is of the form '[ugoa]*([-+=]([rwxXst]*|[ugo]))+|[-+=][0-7]+'.

digits aren't readable to what they mean.
drwxr-xr-x means d,u=rwx,g=r-x,o=r-x, U(u)ser gets Read/Write/Execute permission, G(g)roups get read and execute, O(o)thers get read and execute. + d stands for directory

get used to letters xD

learning digits is a mistake.

[dapper musk]

yes because **u **for file owner and o for other users so intuitive

i prefer doing math because it is simpler and shorter

[dapper musk]

learning never is mistake

[ember quiver]

On the rare occasion that I need it I just use a calculator like https://chmod-calculator.com/

[wise forge]

u beat us all in having best solution 😆

(recording to memory online chmod calculator google request for chmod permissions)

[wise forge]

https://www.gnu.org/software/coreutils/manual/html_node/chmod-invocation.html#chmod-invocation
official documentation mentioned in chmod --help is great though
we could rewrite drwxr-xr-x or 755 as a simple command a=rx,u+w (set all to rx permissions, plus give to user writing in addition)

[dapper musk]

…to as 3 natural numbers who are smaller than 8?

[ember quiver]

If I did it every day (or even every month) I'm sure I'd start to remember what those numbers represent, but I don't

[dapper musk]

yet you remember what u a g mean

[ember quiver]

No I don't 🤣

Darkwind seems to, not me

But of course a letter that stands for a word is easier for (many people) to remember than a number. To each their own 🙂

[opaque ginkgo]

bruh what

user, group, all

easy to remember

even though I have memorized the order of the octal encoding

it's still harder to read than rwxrwxr--

[opaque ginkgo]

the encoding order for the octal digits is rwx
ie r=4 w=2 x=1

so it's not that bad, but the other notation is still easier

[summer surge]

hello, I need advice is my idea is good or bad or even it is a some way to separate users.
I have application written with cmd module. I added application to /etc/shells and it is doing job, It is working and doing thing as I want, when new user is created with access only to this shell it can only run modules which I added to this "shell"
Is there known way to exit from this jail by some way ?

[real vapor]

they kinda are, it's just a bitmask

you have a 9 bit integer

.
  7   5   5 (base 8)
111 101 101 (base 2)
rwx r-x r-x

[wise forge]

correction, it requires way more brain power to read correctly digits than letters.

therefore digits aren't clean code.

[real vapor]

it's second nature to me at this point

[wise forge]

guess what will learn/read faster dev new to both methods.

software development is a team play

[real vapor]

it's so compact though

if I ever chmod something it's so much simpler to just write 755 or 644 or whatever than remembering which letter describes which group

(instinctively thinking owner rather than other for o doesn't help)

[real vapor]

it's not even remembering, it's just reading it as bits, e.g. 7 = 0b111 = rwx, 4 = 0b100 = r--

translating 755 to a=rx,u+w is genuinely more mental effort for me

or parsing the latter

rather than the former

[ember quiver]

I do agree that if I'm applying a standard permission level repeatedly, I'm going to tend to do it that way because remember a set three digit code is easy. But if you ask me what 644 means, I'm not going to do the math when I can just Google it

[real vapor]

it's more effort to google it than to just see that 6 is rw- and 4 is r--

also I think the only ones I ever see occur is like 7 6 5 and 4

maybe 1

2 or 3 would be weird

only w or wx

so you can write and write/execute respectively, but not read

[summer trail]

1 is weird too - you can't execute a thing that you can't read

I agree, you only ever see 7/6/5/4/0 in practice. rwx, rw-, r-x, r--, and ---, respectively.

Overwhelmingly, the common modes are 644, 755, 640, 750, 600, and 700. Regular files rarely have a mode that isn't one of those 6, and I do need to stop and think a little when I need a mode that isn't one of those

Most of my files are 755

hey guys

sorry if this isnt the right channel this is the closest i could find

so im trying to install fedora on one ssd while im already running windows off another, to have a dual boot system. ive seen tutorials online saying to point /boot/efi to the efi partition already created by windows

but based off me trying to install everything on the separate ssd and the boot loader not starting, i can see that fedora requires 600mb for /boot/efi while windows has allocated 100mb

can i safely increase the size of the windows efi partition in the hard disk manager or will this fuck up my system

[fallow tusk]

It should be fine. You may just want to make a backup of the efi partition using dd just in case.

@vapid plover^

Are you installing on a different HD? You could create an EFI partition on that disk and then have it detect the Windows partition on the other drive.

Then you'd just have your BIOS point to boot off the other SSD

[vapid plover]

i tried that but fedora or grub isnt an option in the bios and setting it to the other ssd still makes windows start first

i even tried mounting /boot/efi to the efi partition on C: now and mounting / to some space on D: but still to no avail

when fedora says “reboot to complete installation” it always takes me to windows

wbm seems to take sole priority no matter what i do lol

@fallow tusk

[fallow tusk]

Not sure, then. I don't have a dual boot Windows box any more, so can't say if that's how it's worked/not worked for me :|

The BIOS drive selection should be searching for the EFI partition, iirc.

Nope. Unless you’re talking about something you did in a version controlled dir. what’s the damage?

^ This is assuming your distro doesn’t come packaged with some sort of system restore utility like Timeshift. Worth looking into. Also, when using most commands that can delete/overwrite files, you can pass -i to throw up a prompt if you’re about to do so.

Hi,
Every time I open my terminal I want to go to ~/Documents/Projects in Terminal
My idea was to add cd ~/Documents/Projects to .zprofile
However this conflict with vscode terminal as they now go to projects dir instead of the current dir that i have open in vs cdoe

how to fix this

[fickle granite]

heh

see if vscode puts something into the environment that basically says "yo, shell: this is vscode here". If it does, you can write something like ```
if [ -z ${VSCODE_REPORTING_FOR_DUTY_SIR} ]
then
cd ~/Documents/Projects
fi

[strong forum]

oh ok thanks (:
I've also found this run command in settings
which also seems to do what I want.

[fickle granite]

ah perfect!

so it only affects that terminal program.

you could have different "profiles", too, which cd to other directories.

try sudo apt-get -f install to install missing dependencies, if it wont work then just type sudo apt install python mr hacker

will suprise you thought, but most of hackers that break into systems on daily basis use other non security targeted distro like debian/arch. You wont use all of tools that are available in kali linux throughout your whole career, so its better to install just those that you need. Also most of the time hostname dont stand out among others and they set hostnames like 'thinkpad/debian' 🙂

Is it just me or people with any kind of anonymous avatar are most of the time Linux noobs, know basics of 1 programming language and ask dumb questions instead of googling

[wise forge]

better read how to ask questions in a good way https://pythondiscord.com/pages/resources/guides/asking-good-questions/ and ask your questions here in public
asking in DM is very rude thing to ask, because you don't value other people's time then / and preventing sharing-spreading of knowledge / preventing more quality input from multiple people.
When it is asked in public, your question is answered by any asynchronously available person, while asking in dm you are synchronously bothering specific person without regards if he is busy or not.
Some people answer questions here just for the sake of being corrected by other people and learning more useful knowledge in the process of answering to others
Some people just like to read answers to questions and finding useful bits for themselves. Everything of it will not happen in DM.
@amber tree drop them this text message instead xD

[tall violet]

Jesus this stereotype is fucking annoying as hell just like mr verboof how can you judge someone by fucking pfp? or nickname
I obviously did started not knowing shit about anything just like every one but this pfp I setted up after about 5 years of linux only and coding exprerience in more then 6 languages, it is fucking insane that I have to "earn" to have my own pfp on fucking online platform since when can't you just use what ever you wish
isn't that what's discord and other platforms are exactly about?

And yes I did try googling but if you try to google but that's not exactly helpfull when there is 10 tutorials each using different method from yubikey that's why asked for any one with already setted up pgp key

I already found one guy willing to help and he sended me his config which helped a lot and he said that he was in the same situation few months back and this stuff is just not easy to find.

But yes my original question was kind really shitty I agree with that

Huh? What do you mean by that?

[amber tree]

In mu first message I said "most of the time"

Doesn't mean all the time

What you assumed

[tall violet]

Doesn't change my reaction tho

Still making toxic assumptions and sharing them based on singular picture is stupid and unnecessary

The assumption being wrong makes it just that much worst

But I am maybe just overacting since I am not used to such toxicity, but I just had say that I don't think it's ok

I would never judge you based on your pfp and even more i would never share my judgement over here since it would not help neither would it be polite

[runic goblet]

i share your sentiment. using the phrase "most of the time" doesn't make it right. it's just not very nice, is it?
some people just like belittling people for their own reasons, i can't begin to fathom why though i certainly have some guesses.

[tall violet]

But it seems to be kind of his personality it seems

Being toxic making assumptions etc

So I am not taking it personally at least I know you are treating everyone equali that's nice 🙃

[arctic dagger]

Good afternoon where I am from. Just a simple question. Is the way linux ubuntu stores python different from windows? I'm asking this because I recently switched to Ubuntu, and in windows. All python files are stored in one place while in Ubuntu, python seems to be all over the place abd in different directories.

[fallow tusk]

System programs are stored slightly differently in general, I guess. Rather than having a directory for the program (which may also be the case in Linux), the binary lives in /bin or /usr/bin, libraries in /lib or /usr/lib and then you'll often have common things in some share directories. however, these are all often symlinks to the files which are stored in one place (some systems like to use /opt for that...iirc Ubuntu doesn't.) I assume this is what you're referring to. You will probably also have per-user items in /home/<username>/.local or /home/<username>/.config. This maps more to things you'd find in C:\Users\<username>\... (%USERPROFILE%? - whatever it is )

[karmic elm]

if you want to know where your python interpreter lives on Linux, run the command which python

[river raptor]

hi people someone said if i do this my laptop gets a lot faster is he right?

and he said it will free up disk space

should i do it

what does that command do

[ember quiver]

No, don't ever listen to that person ever again: https://linuxstans.com/sudo-rm-rf/

[midnight osprey]

add -i

it will ask you

though, if it a bunch of files, that would be a huge drag

-i prompt before every removal

[signal ibex]

somebody is getting trolled

[rare hound]

Try doing man rm and read what it says

Would be better for you

Also

The rm removes files

The /* tells the command to wipe the entire drive, the --no-preserve-root tells the command to wipe the disk without root priviliges

Even if you do it purposely, it could wipe the boot partitions such as mbr, resulting in a bricked device

[tall violet]

It's not about root privileges it's about root as the root of the filesystem /

also you don't need that flag if you are using the /* since that will expand to all subfolders of the root (/)

You can test that by running echo /* which will print all folders under /

and rm will have no problem deleting those files resulting into broken system

[river raptor]

what do you mean with bricked?

[potent comet]

thats a little dangerous, are you sure?

[fickle kraken]

anyone here runs python on wsl

i have this issue where i am unable to install any packages with pip on wsl but works on windows

when i stop the program after letting it run for a long time it just gives me a interupt error

[radiant kraken]

afaik its not a good idea to try installing stuff on the system python, usually you'd use something like pyenv or conda to create user-specific python installations first, after which you can freely install packages to that
https://github.com/pyenv/pyenv#automatic-installer

[fickle kraken]

i have

venv as well it doesnt work there too

[radiant kraken]

did you install and set a new global interpreter with pyenv?

[fickle kraken]

ok

fuck

nvm

it worked with venv

ahh my badd

[fickle kraken]

ok i have this question tho venv or pyenv

i have found that venv works well for me why use pyenv

it just seemed more complicated

[radiant kraken]

the builtin venv module you mean? you're limited to creating virtual environments based on the system python's version

pyenv lets you install many different versions of python in a user-specific environment alongside virtual environment creation

[wise forge]

pyenv could be useful just for the sake of default global env being switched too.
for cases when u need to run scripts which don't use third party libs, that is useful

i usually use pyenv + venv (for small script with third party libs) / poetry (for normal projects)

[fickle kraken]

damn thats a lot of virtual envs

[wise forge]

yeah... so great to get away from python to smth else sometimes. Switched with happiness to another language

i remeber this

[fickle kraken]

i mean the only experience i have with java is college assignments so yeah 😂

[wise forge]

My brain just feels pleasure from development in Golang because of that. Code is just shifting to working states within seconds.
TDD and refactoring are finally working

[fickle kraken]

maybe golang might be my thing too who knows

i got placed in my campus and the company uses alot of python so ive been brushing it up

[wise forge]

I use in companies python for last years too.
Persuaded current team project to allow golang for our DevOps team.

Python sucks in AWS lambdas, getting third party libs to lambdas is very not trivial when they have C engines and os deps.
Development in Golang for serverless AWS lambda stuff is magnitude times better

Going with pleasure to continue my work for them

Python is great beginning

But we need more for real quality

[vital dove]

Hello 🙂
New here, started to learn python like 2-3 days ago... But progressing at good sped (i dont have any background in dev)

I'm currently trying to make a python "program" that's gonna run on my OS (arch linux) and do x y functions 🙂

I'm a little bit confused of where to exactly ask my questions, but i'll take a chance to ask it here:

My main issue right now in my learning is the fact that i'm a graphic designer and 3d modeler for game... ive been interacting with GUI programes all my life.... now in a IDE code editor.... I'm having very big difficulties to keep track of my code and where i am in my my code because i dont have any color or visual indicator....

But mostly, having difficulties to plan ahead my code and what's gonna be my 2-3 steps ahead...

Maybe someone has a beginner friendly trick ?
thanks ❤️

Guys

How can i make a arch linux look like mac os

[primal falcon]

csvtool readable test.csv | cat

How can I apply the watch cmd to this so that it updates every second?

[runic goblet]

does something like watch "csvtool readable test.csv | cat" not work?

or were you looking for the -n option for specifying interval?

[primal falcon]

That doesnt format it, oddly enough

[main olive]

very easily
what's your desktop environment

[viscid tundra]

i couldnt even install the arch..

[main olive]

??

[viscid tundra]

this is my first time

[main olive]

oh ok

the arch wiki is great but if u have questions feel free to ask

[viscid tundra]

i didnt understand the wiki

let me tell u the part that i stuck

[main olive]

oh

so basically

@viscid tundra are you on a virtual machine

[viscid tundra]

i mean i want to do a dualboot

i have 1TB SSD

[main olive]

first test on a virtual machine

[viscid tundra]

100gb for linux the rest of them is windows

[viscid tundra]

yeah

[viscid tundra]

for gaming - windows
for working - linux

[main olive]

ok so basically you need a boot partition
it's where your grub bootloader is installed and how you switch between the two operating systems

as you can see it has to be at least 300MiB

if it's UEFI with GPT

if you wanna do a legacy/BIOS installation, then the partition is not needed

swap partition is like "extra ram"
it's slower than ram and it takes your storage

and /mnt is your root partition, where your operating system (arch linux) will live

in order to partition your SSD/HDD, you can use the fdisk or cfdisk command

cfdisk is like the user interface for fdisk

i think arch linux is a bit hard for a beginner, especially if u want to dual boot it

try out some easier distro to understand how these things work
and BTW, windows is ok for work. if u need bash and stuff, using Cygwin/Mingw64 should be enough

[viscid tundra]

windows using a lot of ram

and i dont want to run something behind i mean my laptop's fan is running suddenly and im looking to task manager and there is a microsoft thing working with high perf

[main olive]

why though

[main olive]

the same happens with me when i use visual studio

i have to do ACPI shutdown for it to stop using my ram

btw arch or gentoo installations give you a really good understanding of how linux works, especially gentoo

[viscid tundra]

@main olive im going to install ubuntu

I guess arch is a bit hard for me i hadnt use linux in my life

[main olive]

good decision

you might also like to take a look at linux mint

[viscid tundra]

okey

@main olive is arch more stabilizer then ubuntu ?

[wise forge]

Recommending Kubuntu 22.04 LTS, it has way better interface

[wise forge]

No. Ubuntu is way more stable solution.
Ubuntu, Debian are often used as Docker images and servers

Arch is never used, arch is customized, build yourself from scratch solution

Just be sure to install LTS, they are stable

[viscid tundra]

I downloaded the Ubuntu yeah okey

But i guess i can customize this to Mac Os like appearance right?

[wise forge]

Ergh. Yeah, but major changes to interface is easier to download as distribution.
Kubuntu is Ubuntu + KDE plasma GUI

There are many other main GUI solutions+ Ubuntu

[viscid tundra]

hmm Ubuntu is not a good distribution for mac os like

[viscid tundra]

is it ? @wise forge

[wise forge]

Do u want to install on Apple arm64 hardware
Or u want GUI like macOS?

[viscid tundra]

I want just appearance because it is look cool i have intel core i7 11800h 1TB SSD and 16gb ram

[main olive]

do u mean something like this?

on youtube i keep finding good tutorials for this, but GNOME usually has less customization options than KDE Plasma or Cinnamon.

[viscid tundra]

yeah kinda

Oh so i should download KDE

https://kubuntu.org/ this ?

[main olive]

so ubuntu is shipped with GNOME, so if u want KDE then yes; u need to install kubuntu

[viscid tundra]

i want more customization

https://neon.kde.org/download gotta download this ?

[main olive]

uhm

i don't know what KDE neon is, but i am confused what u want to do
do u wanna install KDE Desktop environment?

and also Ubuntu ?

[viscid tundra]

@main olive IDK u said gnome is less customization so i wanted to download KDE Plasma as u said

[main olive]

i think you should try Kubuntu in a VM and see the customization options

[viscid tundra]

okey

[main olive]

whether it has the gui features u want
you should try out different desktop environments to see which one has the confiugration options that make your desktop look the way u want

[viscid tundra]

each desktop envs has own iso ?

[main olive]

if u install arch linux u can install each desktop environment without having to install another distro

on my arch laptop i run 3 desktop environments for example
i3, cinnamon and gnome

[viscid tundra]

no no i installed ubuntu

[main olive]

no each desktop environment doesnt have an iso

you're now installing** linux distros** which are shipped with a specific desktop environment

so you need an iso file

but for example on a distro on arch linux where you start from scratch, u can choose which desktop environment to choose

that's what i meant

the difference between desktop environments and distributions is confusing for new linux users

[viscid tundra]

yeah xd

okey thanks tho

should remove snap packages ? @main olive

[main olive]

uhm probably not

read about flatpaks and snaps

[viscid tundra]

okey

[wise forge]

this is kubuntu

[wise forge]

this is not kubuntu

What is the difference between pkill screen and killall screen?

[dapper musk]

pkill screen will kill every process with screen in name while killall will kill only process that matches exacly

for example

emacs &

killall emacs

will kill only emacs process

emacs &
emacs-28.1 &
pkill emacs

will kill both

[fickle granite]

also, who tf runs more than one emacs at a time? 🤣

well that was example obviously all hail emacs server

almost got it working right

[dapper musk]

i had been doing this for only 2 years still my custom keybinding do not work in some buffers for some reason

[fickle granite]

what prompted you to start using it, in this the 21st Century? I think of it as a tool for cavemen only

[dapper musk]

it's extensibility and that it uses lisp as configuration

[fickle granite]

indeed, it is extensible, and uses lisp

I'd expect, for most people, "uses lisp" would be a bad thing

[dapper musk]

unlike neovim/vim which use vimscript and lua languages that i despise

[dapper musk]

? why

[fickle granite]

🤷

cuz it's old and weird

nb -- I love it

[dapper musk]

well it is different than other languages but that's kinda the point of making separate programming language. and age is benefit not a drawback because it translates to better community support and more packages
