[paper moon]

Yeah thats a URI for a webbrowser.

[spice gale]

you could have told me that

before

[paper moon]

I did not realize before 😅

[digital prawn]

hmm

can someone tell me why this happens:

according to google and stackoverflow, bash aliases can not have command line arguments

however

alias img='python3 /home/user/my_file.py "$@"'

works as an alias and copies all command line args

alias video='ffmpeg -i "$2" -vf scale=-1:"$1" "$3"' does not work

I know the function workaround, but I am asking why this happens

[real vapor]

because aliases don't take arguments

[shrewd stratus]

the $@ version's probably also not working

[real vapor]

aliases are very dumb

replace this by that

[digital prawn]

i'm saying that the first one i posted works

all evidence i read suggests it should not

is it because it's calling python or something which can interpret command line args itself?

i thought they would still have to be passed through

when I echo them and && my actual command, nothing shows but the command works

so python can interpret the command line args.

[shrewd stratus]

that first one probably "works" because it'd behave the same way as it would if you removed the $@ part

[digital prawn]

let me confirm

you're correct

it does work

so i guess that solves that. no command lines args in aliases.

[trail sapphire]

@gritty grail in here instead, which distro and version are you running?

[fickle granite]

I never never use aliases. Shell functions only.

[main olive]

i tried cropping the resolution of my 1 min 15 second video by deducting only 30 pixels in height at the top
the final video is also 1 min 15 seconds at close to full hd
yet the size is only 1.5 MB
from 20 to 1.5mb
is this normal

it plays well

Using ffmpeg

[trail sapphire]

when you crop the video it will re-encode it so you'll get worse quality even if it would be encoded with the original settings, each round of re-encoding will do this
and with such a dramatic size difference I would guess you are either using another codec and/or encoding it in a lesser quantity

[main olive]

But it’s barely noticeable to my eyes

When I watch it

How such a big change in size

oh

@trail sapphire

yeah it was bitrate

from 2k to 163

[shy igloo]

linux for the win

[simple heath]

is it possible to create a .app file for a CLI application on mac?

[trail sapphire]

@real vapor was just replying to @digital prawn that was the one with the problem

[real vapor]

I meant dumb as in "they don't do anything clever"

not as on they are a bad feature

Hi, I'm trying to add SSH in Ubuntu to my GitLab account, I generated a new one with the command

ssh-keygen -t rsa

and save it in the directory

/home/mohamedhamza/.ssh/gitlab_ssh

cat /home/mohamedhamza/.ssh/gitlab_ssh.pub

and added it to GitLab, but this doesn't work, I think this is because I'm not using the default location to save the SSH which is /home/mohamedhamza/.ssh/id_rsa

so, any help?

[fickle granite]

eval $(ssh-agent) then ssh-add /home/mohamedhamza/.ssh/gitlab_ssh

i.e., your suspicion is correct: ssh doesn't "know" that your key is there, so it's not offering it to gitlab

another idea is to put something like this into ~/.ssh/config:

Host gitlab
  User mohamedhamza
  Hostname gitlab.com
  IdentityFile /home/mohamedhamza/.ssh/gitlab_ssh

then ensure your git remotes all refer to the host gitlab

[dull vigil]

already did all of this and facing the same problem and can't figure out what's wrong :((

[fickle granite]

try ssh -v [e-mail]

paste the output

both github and gitlab have pages for debugging ssh trouble:

• https://forum.gitlab.com/t/how-to-debug-ssh-issues/19756
• https://docs.github.com/en/authentication/troubleshooting-ssh

[dull vigil]

can't find any info that could help me to solve the problem, sorry I'm not an expert in OS at all

[fickle granite]

I don't understand

did you run that command or not?

[dull vigil]

yes

[fickle granite]

so why not paste the output, so I can take a look? i might be able to figure out the problem

[trail sapphire]

it's not related to your problem but i would recommend using ed25519 instead of rsa when generating your ssh key

[shy yoke]

Hey @dull vigil!

You either uploaded a .txt file or entered a message that was too long. Please use our paste bin instead.

[dull vigil]

https://ideone.com/tMMHkS

[fickle granite]

gimme a minute

[dull vigil]

I'll, thx

[trail sapphire]

shouldn't it be just ssh -v gitlab.com (so not to override whats configured) if @dull vigil has a matching host entry in ~/.ssh/config?

[fickle granite]

ok that succeeded -- Welcome to GitLab, @mohammedalihamza!

so if your actual git operations are failing, it's because they're somehow different than what you just typed on the command line

[dull vigil]

no, this is another account, there is another account with another SSH I'm working on

[fickle granite]

ok that's confusing

when you say "this doesn't work", what exactly are you doing, and what exactly are you seeing from your computer in response?

[trail sapphire]

what was the exact command you ran when you got this output?

[dull vigil]

git clone [e-mail]:.......

Cloning into 'konan-backend'...
remote: 
remote: ========================================================================
remote: 
remote: ERROR: The project you were looking for could not be found or you don't have permission to view it.

remote:

Please make sure you have the correct access rights
and the repository exists.

[fickle granite]

that's not the exact command

you didn't type a bunch of ....

[dull vigil]

this is the project URL, I just made a ... to be for example

[fickle granite]

you still haven't told me exactly what you typed

I can't help if you don't give me the information I need

was it simply git clone [e-mail]:synapse-analytic?

[dull vigil]

solved, thank you appreciate that

[fickle granite]

wow, what was the problem?

[trail sapphire]

i'm also interested in knowing what the problem was

[fickle granite]

Your mystery is intriguing to me, and I wish to subscribe to your newsletter.

[dull vigil]

In ~/.ssh/config file I set

Host test_gitlab.com
  User git
  Hostname gitlab.com
  IdentityFile /home/mohamedhamza/.ssh/synapse_gitlab_ssh
  PreferredAuthentications publickey

so when I was trying to fetch the project

git clone [e-mail]:HamzaSynapse/testproject.git

but in ~/.ssh/config the host is test_gitlab.com not gitlab.com
so I have to fetch it via

git clone git@test_gitlab.com:HamzaSynapse/testproject.git

I spend almost two days trying to solve it and my team lead solved it in 1 min 😅

[trail sapphire]

yes, you must use the name of the "host" that you specify for the entry in the ~/.ssh/config file, not necessarily a real/existing hostname
and as you have User git in there you don't need to use git@test_gitlab.com, test_gitlab.com should be sufficient

[dull vigil]

yeah, thank you guys

[trail sapphire]

if you have several accounts you can also model your ~/.ssh/config file like this:

Host *_gitlab.com
  User git
  Hostname gitlab.com
  PreferredAuthentications publickey

Host synapse_gitlab.com
  IdentityFile /home/mohamedhamza/.ssh/synapse_gitlab_ssh

Host neuron_gitlab.com
  IdentityFile /home/mohamedhamza/.ssh/neuron_gitlab_ssh
```you can match many entries using wildcards, and if you want to override something you can do so in a later match as it just reads them all in order from the top down trying to match the different `Host` entries in the file to the "hostname" (which doesn't need to exist in reality other then in the configuration file) specified on the command line

[shrewd stratus]

why the underscore?

[trail sapphire]

any name can be used, but a underscore doesn't usually exist in real hostnames so it's a pretty good choice here i think
one could even just leave out the .com part in the Host entry name as long as it's there in the Hostname directive where we need a real hostname

[shrewd stratus]

nvm. I thought it was some wildcard that I didn't know. the actual hostname contains _

I do have an SSH config with dashes in the name

[trail sapphire]

oh, underscore is just a literal character in the name and has no special meaning here (same with dash)
it's just the * asterisk that hold special meaning here and can match zero or more characters
you can also use ? to match exactly one [of any] character
but i think that is all the wildcards that can be used for a pattern for the Host label

[stiff cloud]

hmm

oh

[grizzled bay]

[trail sapphire]

which dist and version are you using?
what exact version of python and asyncpg do you have installed?

[grizzled bay]

Ubuntu 22.04, Python 3.10.4 and asyncpg 0.21.0

[shy igloo]

Asyncpg is installed how exactly?

[grizzled bay]

I have asyncpg in a requiremnts.txt file (The other packages in the file appear to work) and I did pip install -r requirements.txt and I also tried pip install -U -r requirements.txt

[shy igloo]

any venvs or pipenvs? @grizzled bay or condas

also pip version? @grizzled bay

[grizzled bay]

I did have one but it was throwing the same error (running pip list it appeared that the venv was dragging all of the global packages in as well) so I deleted it and now I'm just running it globally

pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

[shy igloo]

have you tried updating pip or building asyncpg from source?

[trail sapphire]

you have stuff installed under /usr/local so you have used elevated priviliges to install it

[shy igloo]

do you have postgresql? @grizzled bay

[grizzled bay]

nope neither of those, I've never built anything from source so I'm not sure how I would; does asyncpg provide a howto in their repo? and no I haven't tried updating pip, yes I have postgressql installed

[shy igloo]

the docs: https://magicstack.github.io/asyncpg/current/installation.html They have building instrcutions

But you also need postgresql for the tests and building to work

https://www.postgresql.org

[grizzled bay]

when they say cloned the repo with recurse-submodules wht do they mean? I'm not greatly familiar with git in command line

[fickle granite]

I think you can have one git repo "include" another, but by default, when you clone that top one, it doesn't also clone the included one

but if you ask it to include it, that's called 'with recuse-submodules'

[grizzled bay]

thank you

[trail sapphire]

try using pip to build and install the package for you by not using the available wheels
you do this by running pip install asyncpg --no-binary :all:
but you will need to have all the build dependencies installed on your system for that to work

[digital prawn]

Hey guys

[wet folio]

Any idea, whats the meaning of such error message information?

[digital prawn]

Could someone help me with this issue as seen in the attached video? On the left is gnome-terminal and on the right is konsole, the colors you see in the terminal are ANSI colors codes with a space as character. The ANSI color code is set to the foreground, not the background. This means normally, the image is invisible since the characters are spaces. When you highlight them image, it inverts it so that you can see the background colors. The ANSI escape codes are 24 bit RGB codes, not codes within user defined color space. So why in konsole, is it behaving like this? It works as expected in gnome-terminal.

[untold socket]

I cannot view the video but it looks like the right window simply has set an opacity value less than 100%

If that's the problem you're describing

[digital prawn]

hmm

so you didn't see the video? at all?

or just the thumbnail

in the video, i disable the transparency

to check that as well

[untold socket]

I can see a thumbnail

[digital prawn]

ah

it shouldn't effect it based on the way it shows in the video anyway

some colors work

[shrewd stratus]

download the video

[digital prawn]

some just show grey

[untold socket]

It might be the console window application does not support those colors

[digital prawn]

thats so strange.

it's just rgb

24-bit RGB ansi codes

it accepts some of them

clearly, why not all? lol

[untold socket]

¯\_(ツ)_/¯

You can try any RGB value with \033[38;2;r;g;bm (the m is not a typo) where r;g;b are integers in range(256) if you know what I mean (\033[0m to reset)

Use 48 instead of 38 for background color mode I think

[digital prawn]

Roie

not quite sure what you mean try any value. and what you posted is accurate, and is how the program works

but it takes images as input

and converts them to the output

[untold socket]

I don't know what the output is

[digital prawn]

output is what you see in the video in the terminal

the ANSI string

the input is an image

[untold socket]

I can't view the video

[digital prawn]

oh

right

[untold socket]

It just doesn't load

[digital prawn]

same for me

but it works locally

not in browser

[untold socket]

I assumed you mean virtual terminal sequences for console colors

[digital prawn]

by the way

I should mention

you said use 48 instead of 38 for background

this is correct

and it works 100%

all colors show in konsole

in any image

as soon as the 48 is 38 foreground not background

only some colors work

and the rest are grey

[untold socket]

You can try use background color codes and use a virtual terminal sequence to invert the color mode of the console

I don't remember its code

[digital prawn]

i think thats a windows thing?

the video will give more context, maybe you can view it locally and then delete it? but you will see what the use case and purpose is

it has to be foreground color

[untold socket]

I'll open up my computer and try to

[digital prawn]

cool

[untold socket]

In the meantime type or link the message where you explained what it does

[digital prawn]

this?

basically

takes an image as input

takes rgb pixel values

build an string with ANSI color codes using the same rgb values

sets the foreground instead of background

requiring you to highlight the image with your cursor to view it

otherwise it's invisible

which is the whole goal

having it invisible, and view when the cursor highlights

which works in gnome

not in konsole

[untold socket]

I suspect it's a problem of adjusting to the buffer resolution

Meaning maybe you print to few or too many pixel values in a single line on konsole than you do on gnome

[digital prawn]

the output is identical on gnome and konsole

as in the ANSI string

not what it renders

[untold socket]

Just to make sure, are you using os.get_terminal_size to adjust?

It tells how you how many rows and columns the console window currently has

[digital prawn]

no. The only thing I use os.get_terminal_size for is --autosize feature which isn't used in this video

there is no adjusting to size

the height is specified in the command

--height 35

in both terminals

[untold socket]

Have you tried looking at konsole in different window sizes

[digital prawn]

yes, it's the same. there is much more space than 35px

fullscreen no dif

[untold socket]

The width of a line matters just as much as the height

[digital prawn]

yes

its the same the width is based on height

so width is height*2

[untold socket]

That depends on the font I think

And isn't it the reverse

[digital prawn]

when i say width I mean number of spaces, and height, number of spaces

the font only changes the size of the chars

so it would make smaller output

[untold socket]

I just checked because some fonts on Command Prompt change the line and column widths in pixels

[digital prawn]

yes

that's what I mean by size of chars

the block is smaller

itself

not the gap

it makes no difference

[untold socket]

Maybe your program optimizes out characters/pixels?

[digital prawn]

there's more than enough space

it does

--opt in the command

in both

create the SAME

optimization

which is what sets height*2

instead of --opt

its height=height

not height=height*2

i don't know what else you mean by optimize

that is my implementation

[untold socket]

Try printing the line and column values of each character drawn

[digital prawn]

as in, you're looking for the output

the text output

?

[untold socket]

I mean maybe it skips certain pixels to print

[digital prawn]

OH

wait

wtf

hold on

[untold socket]

Just to make sure each pixel is drawn sequentially

[digital prawn]

you got me thinking

so actually

i added a feature that

saves like 25-75% of ram and disk space if you store it

by eliminating repeating ansi codes

so it works like this:

if the next pixel to the right is the same color as the last pixel

dont write an ansi code just draw a space

since the ansi color is already set

but this should have no effect in konsole different than gnome

because i'm not resetting the color

[untold socket]

Are you resetting the color still though

Or maybe konsole auto resets colors

[digital prawn]

weird

[untold socket]

Maybe it's like a harsh setting

[digital prawn]

i'll comment out that condition and try it

hold on

[untold socket]

Have you tried writing a long line of characters starting the string with one color code

If they're the same

[digital prawn]

it made no difference keeping the ansi codes instead of having them account for repeating colors

[digital prawn]

not sure what you mean exactly

[untold socket]

For example

print('\033[48;2;255;0;0m' + ' ' * 20 + '\033[0m')

[digital prawn]

that worked, all red

lets try foreground

worked 100%

highlight showed all

[untold socket]

Since this seems to be a static image shower thing, you can fill a buffer like this and print it

You can build up a string

[digital prawn]

it's one string printed.

with 38 not 48

foreground

background works 100%

foreground some colors work

the output is appended and printed at once

and also, it has gif and mp4 support. but that's not within scope of this issue

[untold socket]

Oh so it really is just a problem of color support then?

[digital prawn]

i guess so.. it's weird

you'd expect that in konsole rgb foreground would have all colors like rgb background

[untold socket]

I found the virtual terminal sequence for inverting foreground and background: \033[7m

There is a virtual terminal sequence to revert this operation other than \033[0m apparently, and it's \033[27m

[digital prawn]

i have a feeling results will be the same if its supported at all

will take a bit to implement this in the app, might give it a try though

[untold socket]

docs.microsoft.com has this in their documentation page about virtual terminal sequences

[digital prawn]

do you know if this is widely supported by linux terminals or just windows console?

i'll test it

in a python term

[untold socket]

As far as I know, from my own experience with my Command Prompt console and from websites documenting this online, virtual terminal sequences are not enabled by default

But that's just for Command Prompt. I haven't checked this on PowerShell

[untold socket]

Virtual terminal sequences are supposed to be supported on Linux too

Here is a link to the page so you can read for yourself https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences

[digital prawn]

so if we did something like:

print("\033[48;2;255;0;0m\033[38;2;0;255;0m    \033[7m     \033[27m       \033[0m")

it works in konsole

but i still don't think it will solve the issue

one sec

yea it doesnt solve the issue

just using 48 and inverting it

[untold socket]

Are you using this https://konsole.kde.org/changelog.html

Maybe they really are only starting to support colors

[digital prawn]

konsole --version
konsole 21.12.3

changelog not showing that

ohh

hold on

i got to scroll down

nah, still don't see it

[untold socket]

Color support seems to be documented on the last entry in their changelog page so maybe it is still something that is worked on and not fully implemented yet

[digital prawn]

I think you're looking at the KDE section?

[digital prawn]

^

[untold socket]

I'm looking at the page link I sent

[digital prawn]

Add color tabs support
Add new ANSI sequences CNL and CPL

this?

sorry haha

[untold socket]

Yee

[digital prawn]

I'm actually using i3 + konsole

not kde, not sure if thats applicable but also

my konsole version is 21+

so idk

also

I don't think color tabs is ANSI related

and those escape codes are not related

[untold socket]

Ye I don't know

[digital prawn]

@untold socket

from time import sleep
min = 0
max = 255
selection = "48" # 38 for foreground
for r in range(min, max + 1):
    for g in range(min, max + 1):
        for b in range(min, max + 1):
            print(f"\033[{selection};2;{r};{g};{b}m \033[0m", end="")
            sleep(0.0000000001)

this generates every possible rgb color

all of them work in background

like half of them work in foreground when I hold my cursor and select it

blues and greens work, yellows dont show

so strange

[nova hatch]

Does anyone have an idea on why I can connect to my server when we're in the same LAN through SSH and IPv6, but it doesn't work when I turn on mobile data?

[vital bay]

does your server have a public ip?

[fickle granite]

and are you using that IP address, and does your NAT setup allow the ssh port through

[vital bay]

the address needs to be resolvable in order to be found. when you're connected to data, you're in a completely different network and your traffic needs to be routed, but it can only be routed if the route is known, which requires it to be a public ip. if not an ip of its own, then a tunneled or NAT'ed one, or something of the like

[nova hatch]

I get the IP with curl icanhazip.com from the server

It's a website that tells you your IPv6 address, which has to be public if they know it, right? SSH-ing into it on the same network works, but as soon as it's from a different network the connection instantly fails (It doesn't even try, the error comes instantly)

It's not a fe80 address.

The error is:
ssh: connect to host 2a00:---:e356 port 22: Network is unreachable

[vital bay]

especially for this, some sort of port forwarding is needed. i'm not sure you'll be getting it to work

the ip you get is the one that your ISP translates to give you access to the internet from inside your private network, but it doesn't work in the opposite direction

[nova hatch]

I set up port forwarding in my router, from port 22 to port 22... I remember trying to get this to work a long time ago, but I just didn't work. We don't get a public IPv4 from our ISP, which is why I've been using a VPS, but they get quite expensive and I've got a few Rpis lying around.

[vital bay]

having an ip be publicly visible on the internet is in general a paid service

[fickle granite]

weirdly in my experience if you're already paying for (say) an ec2 instance, the public IP is free

it's weird because I'd have thought the supply of public IP addresses was more constrained than the supply of ec2 instances

[vital bay]

thanks to ipv6, not really

[nova hatch]

My server has a IPv6 address labeled "IP Address in the internet" in the router configuration page, but ssh-ing into it doesn't work at all.

I guess there's just some problems with ipv6 still. Hopefully they will work everywhere someday just like ipv4 addresses work now. It's really frustrating.

[vital bay]

they both work more or less the same way

[nova hatch]

*should

[vital bay]

your ISP is masking your IP somehow, making it impossible to be reached from the internet in general

if you can't ping your router from outside, nothing to do

no matter what settings you change on your router

[nova hatch]

Ok, thanks, at least I know that there is no stupid simple mistake from my side. I tried calling the ISP support, but they weren't really helpful lol

Thanks again

[fickle granite]

ISP support never is

[vital bay]

you'd probably have to pay extra for that

[fickle granite]

https://www.youtube.com/watch?v=p85xwZ_OLX0

[vital bay]

there is, to the best of my knowledge, no free way to do this

even if you get an ipv6 ip of your own, which iirc were still free up til recently (might still be), you'd need some sort of server to do tunneling for you

[nova hatch]

They offer a static IPv4 for 10€ a month. No thanks, Digital Ocean VPS' are cheaper. Guess I'll just move back to my old ISP and suffer with 200mbits.

[vital bay]

well

i have 4mbps so, good for you 😛

[nova hatch]

Oh, my condolences, I just got used to my Gigabit access so moving back is kinda hard. But that's a real zeroth-world-problem lol. I really shouldn't be complaining...

[trail sapphire]

are you trying to troll the unix/linux people in here with the statement about windows? 😉

[mortal knoll]

It’s always a good feeling when the first install works

[dapper musk]

and screenshoting tool doesn't?

[lavish storm]

on a VirtualBox? 😂

[sand beacon]

How to use linux in windows?I want to start with linux and i downloaded ubuntu virtual box and the linux iso file but it shows error while installing so any other way to use linux in windows?

[fickle granite]

you might be able to use "WSL"

but if you already have virtualbox and an ISO, you should just solve the problem

here's the docs for WSL https://docs.microsoft.com/en-us/windows/wsl/install

[sand beacon]

thanks

[grizzled bay]

How do I set up a python virtual environment on Ubuntu 22.04? I know there's packages like pipenv and venv and I'm wondering if there's any others; If anyone is particular better than the other for ubuntu use

[kind coral]

Gentoo is a bugger to install, haven't been bothered trying

[trail sapphire]

i would say those two are good choices, pipenv don't have it's own virtual environment, it utilizes venv under the hood but gives you another interface to venv and pip and provides other features as well
and i can't imagine that the linux distribution you run would impact the choice here

[mortal knoll]

After I complete my make.conf and ensure everything works on the vbox, i wanna try installing it on the physical machine itself >:)

To be fair, I don’t think gentoo is as hard as anyone who haven’t tried to install it makes it seem. Most of the docs are well written and there’s plenty of resources explaining every little bit

Granted im not using my own custom kernel (im using genkernel) I will get there eventually!

[grizzled bay]

Okay thanks, that's all good to know. Guess I'll use one of those. venv is built into python right? So I might need to install Ubuntu 'drivers' but the underlying environment creation package won't need to be installed?

[trail sapphire]

venv is a part of standard python, but if you use the python interpreter that comes with your linux distribution they may have split it out to a separate package anyways (ubuntu does this, just fired one up with docker to check)
you would need to install that package too if you don't already have it installed to have access to venv, the same goes for pip

[grizzled bay]

Okay thanks for all the help 👍

[main olive]

guys i have a sad news...i mean i guess its a sad news

im going to start using haiku os

im no longer a unix/linux fanboy

damn

[main olive]

good continuation for u

can you add a print(data['network']) to see what you have in there?

[tropic blaze]

thx for replying, but I sorted out the error

[sand beacon]

I have seen that many companies want their employees to have linux experience why is that...I have read that its fast and secured and updates are easily done in linux?? I dont get it windows also provide these facelities right? like security and updates,I read somewhere it was written that updates are easily done in linux what does that mean I mean in windows we just need to go to the settings and update whats so time consuming in that?Just to make it clear I want to know any practical examples from experiences on why linux is asked in jobs

[trail sapphire]

linux drives most of the internet on the server side, connected devices and cloud services, that is why companies sees it as essential knowledge, also licensing is much simpler which is most important in ephemeral/dynamic environments like containers and other cloud computing many times are today

when it comes to updates, imagine that the same process updated almost all software installed on the server at the same time as it updates windows (not only a few othere microsoft components) and that the updates were also much much faster to install

[ocean coyote]

Cloud apps mostly run on linux distros

Since everything's transitioning to the cloud these days I guess it makes sense to want employees to know at least how to navigate around directories, create files and stuff in linux.

It also really depends on the position

Sysadmin, devops, infra admins and such aklimust know linyx nowadays

Developers not sure

[trail sapphire]

it's getting more and more common that all the developers are part of devops teams and are managing there own slice of the cloud deployments that there applications run on, within the confines that has been setup for them

[placid coral]

Is there a way to require confirmation when using the redirect command in bash? > to prevent overwriting files in the case that you meant to append? currently can only find noclobber but that's not exactly what i want

[trail sapphire]

i don't think you can do exactly what you want, noclobber is probably the closest you'll get

[main olive]

Need some help... This happened after I ran fsck on /dev/sda2

It's stuck on that screen rn... No further logs

[mortal knoll]

Do you have a previous update to rollback to?

If not, you should be able to boot a live disk and fix the issue. Gnome display manager seems to be hanging but I couldn’t tell you why unless we see more logs

Network is failing too, but that shouldn’t be causing the display manager to be failing

Can you try and hop into another tty?

[flat kayak]

I can barely read the logs, it looks like systemd is shitting itself

[trail sapphire]

i think that should work
what is your environment (bash on linux)?

how and from where are you sending SIGUSR1 to the script?
and is the script still running at that point or has it exited?

i don't know anything about SLURM and how things are being run by it
but if you were to do this in the shell and try to get it to work there i might be able to help with that at least

add the variables to the echo too, so that you'll know if they are accessible, like:

_copy() {
    echo this runs with ${GAUSS_SCRDIR} and ${INPUT_DIR} >> message.output
    cp -r "${GAUSS_SCRDIR}"/* "${INPUT_DIR}"
}
trap _copy SIGUSR1
```and don't forget the `""` around the variables in your commands when working with arguments to commands like that (or you'll have problems if anything contains space or other special characters)

so, have you had time to test it out yet and how is it turning out for you?

[upper prairie]

What's that supposed to mean?

[trail sapphire]

you could use something called a "here document" which will make your script that generates the script a lot more readable and easier to edit
within a here document you only have to excape \, $ and ' with \ if you don't want the variable to be expanded by the script that generates the other file
here's an example (and __END_OF_SCRIPT__ is just a delimiter, could just as well be EOF or something else) that uses both expansion and not for different variables:

#!/usr/bin/bash

SLURM_FILE="slurm.sh"
PWD=$(pwd)

cat > "$SLURM_FILE" << __END_OF_SCRIPT__
# This is the script ${SLURM_FILE}
export INPUT_DIR="$PWD"
export GAUSS_SCRDIR=/mnt/storage_2/scratch/gaussian/\${SLURM_JOBID}

_copy() {
    echo Safety copy — this runs with \$GAUSS_SCRDIR and \$INPUT_DIR >> "\${GAUSS_SCRDIR}/safety.message"
    cp -r "\${GAUSS_SCRDIR}"/* "\${INPUT_DIR}"
}
trap _copy SIGUSR1
__END_OF_SCRIPT__

[trail sapphire]

yeah, this was just a suggestion for improvement for how you generate the script, but you'll still need & and wait

[placid coral]

Has anyone experienced this? Running a project in pycharm using the venv python interpreter and trying to activate my venv simultaneously in the terminal so i can run certain commands, however whenever i activate it it seems to break the terminal, any command i type in is not found and with every command i enter it also posts grep and sed not found

using git bash on windows

[fickle granite]

my guess is that the activate file is messed up

it's modifying PATH in a way that omits the directories you need, like /usr/bin and stuff

type echo $PATH to see what it is

here's what mine looks like learning-grosbeak% . ./venv/bin/activate (venv) learning-grosbeak% echo $PATH /home/ubuntu/venv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin (venv) learning-grosbeak%

I'm guessing yours is pretty different

[upper prairie]

Does Git Bash even have ls, grep and sed?

[placid coral]

ye, it's pretty good

[trail sapphire]

it will be quite different for you since your on windows even if you are running git bash in windows it will be quite far from a real unix or gnu environment

[upper prairie]

Idk if I'd suggest using git bash

[fickle granite]

it's the standard thing; visual studio code recommends it

[placid coral]

It's been perfectly fine for java development

what would you suggest instead? just cmd/ps?

[upper prairie]

PowerShell 7 + WSL2

kinda hard to beat with that

[placid coral]

(venv) ~/Documents/python/Django/Website $ echo $PATH

bash: grep: command not found
bash: sed: command not found

[placid coral]

wsl2 is just dumb slow to load though isn't it

[upper prairie]

Not really

After a reboot, the first load can take a few seconds

[placid coral]

idk i used to use on previous pc and if it hadn't been opened recently it could easily take 10s to load

[upper prairie]

but it stays running in the background

[placid coral]

ik a lot of people that have had issues with wsl tbh

this is the only issue i've ever had w git bash

[upper prairie]

I don't think I know anyone

[placid coral]

maybe unlucky

[fickle granite]

That is a mess. There shouldn't be backslashes in there, I don't think

[upper prairie]

Well, they're Windows paths

I would think it's a git bash thing

[fickle granite]

that's WIndows

[upper prairie]

that looks like WSL, though

[placid coral]

might give wsl2 another try

[fickle granite]

oh, you're right; it is

[upper prairie]

Anyways, I've heard of fewer people having issues with WSL than git bash

and I feel like more people use WSL than git bash (here, I mean)

[placid coral]

I guess it's a small sample size, but I know 3 people personally that had wsl issues and none w git bash, though it is likely more simple than wsl

[shrewd stratus]

nice username and hostname

[upper prairie]

What were their issues?

[placid coral]

I don't remember tbh, I didn't really probe as I didn't anything about it at the time

[upper prairie]

Well, I think it's worth a shot anyways. Pretty easy to install, now

[fickle granite]

I wouldn't try to use windows python with git bash; the activate script probably isn't doing the right thing

[upper prairie]

just like wsl --install -d Ubuntu

[fickle granite]

[placid coral]

Yeah it'd be nicer to have wsl it definitely has some advantages

[fickle granite]

yeah that's messed up somehow. You should have mostly forward slashes in there

[upper prairie]

that is curious

but something I'm glad I don't have to deal with

[placid coral]

😄

[mortal knoll]

Exactly lol, you can get this with any init system

Idk if the guy fixed the problem, but could always just reinstall from a live image but make a backup and copy to another storage or something

Just gotta mount the drive and you’re good

[foggy swallow]

guys, any idea why i can't install wine32 ?
libwine:i386 : Depends: libvkd3d1:i386 (>= 1.2) but it is not going to be installed

[ember quiver]

I googled it for you: https://askubuntu.com/questions/1275983/unable-to-install-wine32-due-to-broken-packages

[main olive]

gecko linux + python = win win

[frosty hazel]

arch linux >

[main olive]

arch is cool and all but gecko is perfect for both newbie and advanced users

[upper prairie]

I hope by "gecko" you mean openSUSE \😩

Oh, what the heck... "gecko linux" is a thing

and it's based on openSUSE

oh, it actually looks incredibly useless .-. it's literally just openSUSE but with some stuff pre-installed

[vital bay]

well, if it brings what you want 😛

in that sense, all distros are useless. you could just hand-pick what you want to sit on top of the linux kernel yourself

[upper prairie]

Well, I mean compared to openSUSE

I'm not exaggerating when I say it's literally just a few packages

which is simple stuff like a NVIDIA driver, packman... and that's all I can honestly remember from what I've read

[vital bay]

i'd say nvidia drivers and a different package manager are already pretty good things

[upper prairie]

packman isn't a package manager

not to be confused with pacman

[vital bay]

ah, i thought you meant pacman and miswrote it, that was my bad

[upper prairie]

and the NVIDIA drivers on openSUSE are as simple as sudo zypper in nvidia-glG06

[vital bay]

ah, it's a repo

[upper prairie]

Indeed

and all you have to do is opi codecs and you'll have all of that

[vital bay]

yeah maybe not that good a deal then

but you also have to add in the nvidia repo first, don't you?

[upper prairie]

Not on openSUSE, no

[vital bay]

i see. i haven't used it in a long time, i'm out of touch

[upper prairie]

Well, maybe I lied actually

It's been a while since I installed NVIDIA drivers that way

For some reason those drivers are usually borked so you have to install manually via the .run

https://opensuse.github.io/openSUSE-docs-revamped-temp/install_proprietary/

it's not that much of a process regardless, especially with YaST

[vital bay]

yeah, my experience is that there's usually some reason or another that makes nvidia drivers at least not immediate on most package managers. i would say if one is just starting out, that could be something useful to have taken care of for you

like with pop os (though that one brings a bunch of other stuff too)

[upper prairie]

Well, Pop!_OS has definitely lost its charm

With Ubuntu, you can have the drivers installed if you pick the option during the installer

so really if you use Pop!_OS, you're probably picking it because of the DE

[vital bay]

hmm yeah, that's true. i forgot 22.04 gives that option

[upper prairie]

Even 20.04 did

[vital bay]

oh, that i didn't know at all

[upper prairie]

Idk if the name of the option has changed recently, but it was something like "Install additional software"

which was the option for proprietary software

[vital bay]

aha, yeah, i didn't know that included nvidia drivers

[main olive]

nah openSuse is bad

[upper prairie]

what

[main olive]

i kinda like gecko having minimalism look and feel

like it has vlc and firefox installed out of the box and not some weird video player

[upper prairie]

Firefox is installed by default on openSUSE

[main olive]

also no games preinstalled

[upper prairie]

You get to choose which packages are installed during openSUSE' install process

if you don't want the games, uncheck the games pattern

[main olive]

wait for real?

[upper prairie]

Yes

[main olive]

damn

[upper prairie]

That's one of my favorite features of openSUSE

[main olive]

how come installers dont have that

[upper prairie]

No clue

[main olive]

arch also has that option but im not really a fan of rolling release lol

[upper prairie]

I like rolling release in the way that openSUSE does it with openSUSE Tumbleweed

[main olive]

does it follow the same formula like fedora?

with the updating

[upper prairie]

No, it's pretty different

Updates are rolled out in the form of snapshots

That way, if something breaks, you can just rollback to a previous snapshot

It's not like Arch where everything is updated instantly

you have to wait for a snapshot to be released

[main olive]

i see

so it has timeshift

[upper prairie]

I've had a lot more stable of an experience on openSUSE Tumbleweed compared to Arch

[upper prairie]

I'm not totally sure, honestly, I've never used timeshift

[main olive]

same lmao

but its kinda painful to have snapshots like they take a huge amount of space

[upper prairie]

it's a bit hard to explain, I've never even had to use them

but they're not those kinds of snapshots

[kind coral]

never tried arch but I know I have never had any issues with Void which I am using and is rolling

[upper prairie]

What is it about Void that compels you to keep using it?

[kind coral]

It's bare bones and has a very large repository that is frequently updated

the xbps package manager is so nice too

[upper prairie]

I assume by "depository" you mean "repository"

[kind coral]

yeah mb

[upper prairie]

but also Void is notorious for supporting significantly less packages than other distros

[kind coral]

is it?

[upper prairie]

I guess that's just what I hear from the Void dissenters

[kind coral]

the only package I have struggled to get which was recently added was libgccjit which is a very obscure package because really the only people using are native comp emacs uses which is a minor group of emacs uses who alone are a minor group of programmers

[kind coral]

We don't have it just quite as good as the AUR but in terms of other distros it's very good

[upper prairie]

I'm not sure, I just never thought of Void as really having anything going for it

For the most part, I only ever see people using Void because they have a strong dislike towards systemd

usually completely unfounded in that regard, though

[kind coral]

If you're looking for a barebones distro it sits between Gentoo and Arch

[upper prairie]

I'm not sure I agree with "barebones," though

[kind coral]

why?

[upper prairie]

For the most part, it ends up being people obsessing over disk space that would hardly affect them otherwise

I would understand caring about like CPU and RAM usage

but that's pretty consistent across distros, mainly because it's the DE that becomes hungry for those

[kind coral]

thats why I use dwm

well

not really

[upper prairie]

but when you can use any WM on any distro, does "barebones" really mean as much as you think it does?

[kind coral]

I prefer a tiling window manager because it's more ergonomic

[upper prairie]

because to me it's usually just a psychological thing, not a practical thing

[kind coral]

you're right tbh

if I were to be using the gnome image this would be a different conversation

[upper prairie]

I used to fall into the whole minimalism religion, but I guess I've since discovered that I really don't need to care about it

I suppose it's kind of a rabbit hole at first

You want to see how far you can push it once you kind of move away from like Windows and macOS

[kind coral]

imo gentoo is just way too far

[upper prairie]

and I don't think anyone can really disagree

[kind coral]

there is no need to build everything from source

[upper prairie]

but IMO Gentoo at least has something you can't beat for those who know what they're looking for

like with Gentoo, it at least deserves some respect in my book

[kind coral]

Installing Gentoo does sound like an adventure and a half

[upper prairie]

It's definitely not everyone's cup of tea but at least it's good at what it does

[kind coral]

I have too many headaches right now like setting up this tcp server in clojure

[upper prairie]

I've felt that way about a lot of things

I cannot be an enthusiast, I don't like putting too much thought in what I'm using

[kind coral]

I am a rust and emacs cultist enthusiast

[upper prairie]

Maybe I'm just depressed \🤔 I can't really be enthusiastic about anything, huh

anyways, this is why I happen to like openSUSE \😩 I don't need to put in much effort to have a system that I can trust won't break spontaneously

Even something as simple as being able to pick my packages during install

love that, need more of that everywhere

[torpid cipher]

some people just want a distro that's ready to go so they can get to work, and don't want to fiddle with things, and that's perfectly fine

suse, rhel, ubuntu, whichever

[mortal knoll]

You can install gentoo without needing the gentoo live ISO meaning you can load up your favorite distro and install gentoo through a GUI. It also make’s typing commands easier because you can simply copy and paste what you need specifically

So things like WiFi can be setup easier if you’re installing on physical hardware

That’s supposed to be one of the better ways of installing (which I’ve never tried) but it makes sense. You can even easily download the tarball without having to use links / lynx as well

[carmine meadow]

I use arch btw

[trail sapphire]

you might want to read the topic of the channel

Tooling, setup and configuration related to Python development on unix or unix-like systems such as Linux or MacOS.

[light gorge]

Is there a channel like that for windows as well? Would make sense as Windows is a top platform according to PSF survey

[vital bay]

you can ask about windows stuff in any channel

this one is for more nitty gritty stuff, but you can also ask about linux stuff in other channels. i guess what you said is the reason itself, many people are already working on windows by default, so it doesn't need a dedicated space

[trail sapphire]

i think many of the problem areas when working with python on windows is many times related to and solved in #editors-ides
but i might be wrong and maybe it's just my inexperience with working on windows as a development platform for python

[upper prairie]

It's mostly PATH stuff lol

[trail sapphire]

yeah, mostly, but i'm also very used to be able to run pyenv without a problem for my environments, that can be a bit more challenging to get running on windows (there is such a project, but...) 😄

[torpid cipher]

the thing to do on windows is just use the WSL

imho

[trail sapphire]

depends on if you require windows specific APIs in your code
you might be developing some python code that is specific to the native windows python interpreter
then you can't go with WSL as far as i know

[proven ridge]

Hello!
Please, is it okay to share a project here?

[dapper musk]

Why not?

[tight badge]

what’s unix

[upper prairie]

tbf this channel would be better named "#unix-like"

[trail sapphire]

are you just writing something in all the channels to get voice verified?

[upper prairie]

They've already met that requirement

[tight badge]

what

i can get voice verified that way?

i don’t even want it

[upper prairie]

You need like 50 messages, which you're already way past

[tight badge]

oh

lmfao

[proven ridge]

Hello!

I've just released a new version of term-image. It's a Python package including a library, a CLI and a TUI for displaying and viewing/browsing images within a terminal.

It currently supports a whole lot of features including:

• Extensive API
• Kitty graphics support
• iTerm2 inline image support
• Support for PIL images, file paths, URLS
• Animations (even transparent ones)
• Browsing image directories recursively
• Automatic terminal support detection

Displaying an image can be as simple as

from term_image.image import from_file
image = from_file("path/to/image")
image.draw()
# OR
print(image)

with python, or

$ term-image path/to/image

from a shell, and as extensive as possible...

Links:

• Source
• PyPI
• Docs
• Gallery

The project is open to contributions and I welcome everyone with knowledge and/or experience that could benefit the project.

Thank you very much!

[untold socket]

Does it support path-like objects? Well, I suppose you could use pathlib and call str on the path object yourself as a user

[proven ridge]

It's one of the planned features but like you said, str(obj) will work for now :).

I know implementing this is actually trivial but if I think like that about every other trivial feature, I'll end up not releasing any version of the project till everything is done :)

[foggy swallow]

is there some strong boy from debian?

[shy igloo]

Wow, this is some shit

[upper prairie]

I can't figure out if this is a compliment or an insult

[shy igloo]

Hey, it works pretty well...

[proven ridge]

Thanks for the compliment 😂 😇

[bright raven]

Hello! Anyone willing to help with building python from source?

[shy igloo]

although one image didn't display a previre but displayed fine in the terminal

It was very tall

Also maybe could you make it so if they're aren't any images it reverts to a directory list?

[shy igloo]

Do you have python tarball?

[bright raven]

i'm using the 3.10 branch from github

should i use tarball instead?

Linux darmok 4.15.0-180-generic #189-Ubuntu SMP Wed May 18 14:13:57 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

[shy igloo]

Probably use the tarball

[upper prairie]

I'd suggest using pyenv

Makes the whole process so much easier

Once you have pyenv installed, you just pyenv install 3.10.5; pyenv global 3.10.5, for example

[bright raven]

can i use pyenv without root access?

[upper prairie]

Yes

[bright raven]

i'll check it out thanks!

is it like the nvm but for python

[upper prairie]

I think so, actually

[proven ridge]

🤔 ... I don't think I understand what you mean here.

[proven ridge]

Well... that would be a file browser then 🤔 🤷‍♂️

To be clear... you mean in the TUI, right?

[trail sapphire]

very much so, if you use it as root you can even mess up your own shell pretty bad if your not very careful
so i always suggest people always use it as another user then root

[bright raven]

OpenSSL doesn't seem to be installed on the computer

[shy igloo]

Yes

[bright raven]

since I don't have root, I'm thinking I have to

1. Compile OpenSSL from source
2. install it into some alternate directory
3. ???
4. Install python

[trail sapphire]

that is an odd one, most distros has it unless they are super lean and use something else

[trail sapphire]

you don't have root access on the system so you can't use the package manager to install it?

[bright raven]

yup

i can't use apt install

[trail sapphire]

because you're not allowed to do sudo -i or su -?

[bright raven]

^ yup

[proven ridge]

I see. Well... I'll sincerely like to keep it strictly images. 🙂

[trail sapphire]

that's too bad, otherwise you could simply have installed the packages you need for building
i think you might get problems if the system don't have the required packages installed on the system to build python and no way to install them

[trail sapphire]

i think your best bet would be to setup a system with the same version of ubuntu and install all the required packages there and build it all there as well and then just transfer the files (including dependencies) over to the other constrained system, but it will not be a walk in the park

[bright raven]

pain

[trail sapphire]

yeah, you're in quite a pinch if you need to use that system and can't use something else instead

[dapper musk]

If you have physical access to computer you can gain root easily. Reboot and when grub menu appears click e then add init=/bin/sh to kernel parameters and press f10 and it will drop you to root shell

[bright raven]

uhhhhhhhhhh thanks for the tip but I don't have physical access LOL and I'd rather not get expelled from my university

[trail sapphire]

and you can't ask for some packages to be installed on the system that you're working on?

[bright raven]

i could but it usually takes them days/weeks to respond

i got it through pyenv actually

but now i have a separate issue that doesn't seem related

[trail sapphire]

oh, the system had enough packages installed to be able to build python for you?

[bright raven]

yeah it did

[upper prairie]

Can you where python?

[bright raven]

i had to build openssl manually

[bright raven]

i created a virtualenv with the pyenv binary

[trail sapphire]

ouch, but good that you got through it

[bright raven]

It's a folder our university uses for... scratch space

i just needed to upgrade setuptools

thx for all the help through these troubled times ❤️

[trail sapphire]

nice, happy to hear that you're on track again 🙂

[slender whale]

help needed with general linux question (not python related). I'm setting up an SFTP server and want to create a /ftp folder where files will be uploaded to. All that is OK. I want to create a user that can only use a subfolder . I think I have done the chgrp and chmods properly but the user keeps getting an error when logging in that they can't cd to the proper directory

any ideas what's wrong ?

ah got it ..... chmod settings were wrong

[trail sapphire]

you would run something like: find . -name '*.log' -size -10k -exec sha256sum {} \; 2>/dev/null
the first . in there is the current directory, you can set it to /var/log or what ever you want instead
the - in -10k means less then and k is KB for the arguments to the -size option
sha256sum can be any command you want (just be careful) and {} means the name of the current file and the \; is absolutely necessary to tell -exec that the end of the command has been reached
and finally 2>/dev/null suppresses any error messages from find and the command find runs with -exec for the matching files

Hi guys, facing problem with GDB:) So I did GDB using below command gdb ./combined/afl-image/afl-fuzz And the code I am trying to check its under ./combined dir . So, once I went gdb mode using first command I typed break ../Program.cpp:Program:deserialize(some args) but after that I can not do anything using some command line info line 200 or print, trace etc or other command from gdb doc, any suggestion how to read specific line

install discord-installer or discord-canary-installer

oh, through opi

sudo zypper in opi

then opi discord-canary-installer

what the

hmm if I had to guess... it's because you're on leap

well

I assume you're on Leap

I guess whoever made that package doesn't support 15.4

oh yep

I guess you could try

zypper addrepo https://download.opensuse.org/repositories/home:simonizor:discord/openSUSE_Leap_15.2/home:simonizor:discord.repo
zypper refresh
zypper install discord-canary-installer

some of those you'll need sudo

I dunno which, I just know the last one for sure

Neat

Anyways, if you've ever heard of the AUR, this is our "equivalent": https://software.opensuse.org/

[steep sequoia]

#! /bin/python3

import os

glob = globals()

glob["echo"] = lambda *args: os.system(" ".join(("echo",)+args))
glob["clear"] = lambda *args: os.system(" ".join(("clear",)+args))
glob["touch"] = lambda *args: os.system(" ".join(("touch",)+args))
glob["rm"] = lambda *args: os.system(" ".join(("rm",)+args))

touch("testfile")
echo("test", ">", "testfile")

file = open("testfile")
print(file.read())

rm("testfile")

bash in python

the scripts output is "test"

which is what was echoed into the file :D

then the file is removed

so that it doesnt clutter up whatever directory you're in

[upper prairie]

lol I'd just use iPython for that

also what you're doing with glob and what-not, you might prefer to just use a partial from functools

actually I lied... You do fancy stuff with + args

[steep sequoia]

thats just for the "".join lol

you can do it without +args I think

[upper prairie]

right... one second, let's find out

[steep sequoia]

with echo:

"echo "+" ".join(args)

does the same thing as

" ".join(("echo",)+args)

[upper prairie]

uhh... I kinda hate how os.system() works

[steep sequoia]

i dont remember why i picked this one over the other way lol

[upper prairie]

now that I think about it

[steep sequoia]

looking back on it, the `"echo "+str.join is better

[steep sequoia]

do tell?

[upper prairie]

this whole "only one arg with words split into a sequence >:("

[steep sequoia]

yeah thats a bit dumb

[upper prairie]

I'm on Windows, but

In [1]: dir_ = !dir

In [2]: !echo "Meow, world!"
"Meow, world!"

imagine dir is ls

[steep sequoia]

dir is also a command lmao

it does basically the same thing as ls but the default formatting options are slightly different

[upper prairie]

lol

❯ where dir                                                                                                             dir: aliased to ls -l 

Never knew that, never used it

[steep sequoia]

lol

[upper prairie]

anyways, your glob thing is useless regardless

glob["echo"] = would just do the same as echo = , no?

except more expensive

or... I'd think more expensive

[steep sequoia]

yeah its more expensive

i was originally doing it because i wasnt in the global namespace

so it would put it in the function namespace, then remove it when the stack frame got deleted

i wanted it to be global

but then i decided to play around with it, and i largely just pasted in my previous code lol

but yeah, you're right
glob[] is more expensive

and unnecessary

[upper prairie]

I honestly don't like touching the shell at all from within Python

feels so... dirty

[steep sequoia]

i was doing it bc i wanted to invoke gcc from python

then i got distracted and started playing around wiht it

*with

[stone timber]

hu

[upper prairie]

I feel like with something like gcc, you'd want your main "thing" to be a shell script

like check the exit code of the script or something and do something based on that

but that's just me \😩

[steep sequoia]

the reason i didnt use a shell script is for speed

shell scripts tend to be much slower than python

and bc im writing a relatively large/expensive thing, shell script was too slow

[upper prairie]

but then again... you're having to use os.system()

which I think would come with a bit of overhead compared to running a script directly

[steep sequoia]

in my actual project, only to invoke gcc
everything else was done with python

[upper prairie]

oh, I see

I guess I just wish Python felt more like it was meant to do that kind of stuff

[steep sequoia]

the geniuses in #esoteric-python once did something that made it so that you could call functions like this, iirc:
fn arg1, arg2, etc

it was a while ago, but if i could find that, i could make bash in python lmao

or at least, make it much more natural to use

[upper prairie]

I can imagine something like cmd: arg1, arg2, arg3 being possible

but I dunno about anything else

eh, maybe not that

Well, you could cmd: "arg1 arg2 arg3"

[steep sequoia]

yeah it was smthn like that

[steep sequoia]

yeah it might be that
my memory is bad lol

[upper prairie]

Cursed; whatever it is

[steep sequoia]

this lovely script by someone called apple does that

@type.__call__
class __annotations__(dict):
    def __setitem__(self, item, value):
        print(value)
print: 989
print: "foobar"
print: 3*8-9

though looking at it, i think it only works with print

bc print(value)

but you could mess with that and get it to work with whatever function you use it with i think

how did the 2022-07-02 21:34:41 get there?

did you type it?

No difference for me \🤔 (other than the time itself, naturally)

I'm trying to install python on ubuntu, but I can't manage to do so... I uninstalled python 2.7 and installed 3.10 using apt but it just says

catow@catow-H470-HD3:~$ python --version
bash: /usr/bin/python: No such file or directory```

[upper prairie]

python3, not python

also where did you get Python 2.7?

[light blaze]

builtin I guess

[upper prairie]

shouldn't have done that, then

[light blaze]

and it says now Python 3.8.10

not 3.10.5

[fickle granite]

you should post a complete transcript of all the commands you ran

[upper prairie]

try python3.10

[light blaze]

yeah I know that works

but where did 3.8.10 come from

[upper prairie]

Preinstalled, likely as a dependency for some package or internal script

[light blaze]

most likely

[upper prairie]

same with 2.7

You probably shouldn't have removed it, since it came with your installation

[light blaze]

I've installed the OS a long time ago, not properly either. I will reinstall everything soon when it bothers me enough with too many issues, but right now it's a bit chill

[light blaze]

yes I figured that out after removing it lol

good to know for next

[upper prairie]

You probably want to use something like pyenv, to keep the preinstalled versions of Python intact and usable by the system

[light blaze]

oh

[fickle granite]

I just meant "all the commands you ran where you were trying to remove or install python"

[light blaze]

sending

[upper prairie]

Once you've got pyenv installed and setup, all you do is pyenv install 3.10.5; pyenv global 3.10.5

[light blaze]

sudo apt install python3.10
sudo apt remove python2.7 (sorry lol)

[upper prairie]

python -V will be 3.10.5, python3 -V will be 3.10.5, python 3.10 -V will be 3.10.5

[fickle granite]

those seem sane

[upper prairie]

same for pip, pip3, etc

[light blaze]

not my favor here

[upper prairie]

When working with Python on *NIX, I will forever praise pyenv

[light blaze]

so yeah pyenv will do well

[upper prairie]

Well, that's if you install with pyenv and set as global

[light blaze]

yeah yeah now installing

[upper prairie]

You may want to reinstall 2.7

[light blaze]

I think I'll just reinstall the operating system

I don't like ubuntu

[upper prairie]

but also it sounds like maybe you're running an older version of Ubuntu

[light blaze]

I'll switch back to arch

[upper prairie]

Why not?

[light blaze]

I was just lazy one day and decided to install ubuntu

[light blaze]

there are too many things I wanna change and too many things I don't want

[upper prairie]

Beyond the DE, I don't know if I see what you could be talking about

[light blaze]

because I once had arch but then decided to try ubuntu again

unrelated to python now, I just don't like ubuntu because there are many things that I need to change or don't need, which I can just directly get on arch and not bother about what I don't need

[upper prairie]

That must've been years ago

[light blaze]

a year ago

[upper prairie]

Ubuntu hasn't shipped with 2.7 in a while

You would've been using something like 20.04, no?

[light blaze]

yes

[upper prairie]

I don't think 20.04 came with 2.7

[light blaze]

lemme clarify the version I have wait

[upper prairie]

but also 20.04 is about two years old now

[light blaze]

yep 20.04

I'll remove ubuntu in a few days

I'll get a new piece of SSD that I've been wanting to get for quite a while

and then install arch

[upper prairie]

Yeah 20.04 doesn't come with 2.7

https://releases.ubuntu.com/20.04/ubuntu-20.04.4-desktop-amd64.manifest

[light blaze]

which is really odd, I bet I installed something that it went along with

without noticing

[upper prairie]

tbh, I'd say it's worth trying out a 22.04 flavor

[light blaze]

yeah alright I'll give that a shot

and if that doesn't go well with me I'll switch back to arch

[upper prairie]

I might suggest Kubuntu or KDE neon

[light blaze]

KDE is my favorite

why not plasma?

[upper prairie]

Kubuntu and KDE neon are both distributions that come with KDE Plasma instead of the GNOME like on Vanilla Ubuntu

KDE neon and Kubuntu are very similar except KDE neon is from KDE themselves and comes with the latest versions of KDE Plasma

[light blaze]

I mean on arch I use xfce but like with ubuntu I find KDE more similar rather than kubuntu

[upper prairie]

https://ubuntu.com/desktop/flavours

[light blaze]

oh alright

thank you very much

[warped nimbus]

Ubuntu itself is alright but not a fan of Canonical so I stay away from Ubuntu

[light blaze]

what are you using then?

just curious

[warped nimbus]

Arch and Debian

[upper prairie]

There's only one thing about Ubuntu that I do not like

and that's snaps

[light blaze]

that's far better imo

[upper prairie]

debatable, honestly

[light blaze]

I tried arch and debian but I stayed with debian only for a little

[upper prairie]

I'd never use Debian for a desktop

[light blaze]

arch was so much lighter and faster but I mean that's just probably because I installed some things poorly when I installed debian

[upper prairie]

I understand and can justify its use in servers, but not so much a daily driver

[light blaze]

yeah I uninstalled debian after a day 😅

[upper prairie]

Arch... I just don't like kind of altogether

[light blaze]

I mean I still liked it, better than ubuntu imo

[upper prairie]

maybe the only thing I actually like about Arch is that it's a rolling release

but in my opinion, openSUSE Tumbleweed just does everything better

[light blaze]

might be right yeah

[warped nimbus]

Canonical has made some poor choices like sending some user data to Amazon and also showing ads.

So I have a sour taste in my mouth

[upper prairie]

As soon as I read "poor choices", I knew what the rest of the sentence was lol

but also wasn't that like 6 years ago

[warped nimbus]

Yeah. maybe I am being petty but when there are so many other choices for distros I can afford to be so

[upper prairie]

I've basically landed on two distributions

Ubuntu and openSUSE

and honestly I don't see myself ever seeing much of a benefit in anything else

[light blaze]

I think I just fell for arch the first time I met linux distros I really have no idea why

I think it's because I saw it as a challenge

"to install something that's considered to be advanced"

[upper prairie]

I don't think I like how popular Arch is

[light blaze]

and it got stuck in my head

[light blaze]

there are many reasons though

I find it justified

[upper prairie]

I don't think I'll ever see it as justified

[light blaze]

what'd you think would be a better replacement then?

[upper prairie]

I feel like beyond the annoying installation process, there isn't terribly much to like about it

[upper prairie]

I feel like openSUSE Tumbleweed is quite underrated

[light blaze]

that's the whole idea, the customization

[warped nimbus]

I like rolling release and AUR 🤷‍♂️

[upper prairie]

Just wait until you see TWs rolling release and the OBS

Much better in both regards, in my opinion

[light blaze]

👆

[upper prairie]

In the year that I used Arch, I've had so many things break just from casual use

Eventually I got tired of fixing the most random stuff, so I switched off of it and found openSUSE Tumbleweed

[light blaze]

but OBS is a screen recording and streaming software

[upper prairie]

Open Build Service

https://software.opensuse.org/

[light blaze]

I know lol

[light blaze]

I can relate to that in a week of usage

[warped nimbus]

Okay I have no loyalty to Arch. Maybe I will check it out. But when something is established, and I don't have any major grievances, I can't really justify the effort to switch.

[upper prairie]

I felt the same until I got fed up with Arch lol

[light blaze]

yeah well I'm honestly just used to windows so much that I have a hard time getting to know linux, which is why I picked arch in the first place

[upper prairie]

I mean that kind of happened a lot for me

but openSUSE has a lot of benefits

One of my favorite being the YaST installer

during the final step, you can choose what software is automatically installed

You get to look through all of the patterns and only install what you want

[light blaze]

oh I didn't know that

that's a nice feature

[upper prairie]

It's fantastic

and that option will exist post-install in YaST

You can look at all the patterns and choose software to install in a GUI

An example of a pattern which might be appealing to you is the "Python development" pattern

[warped nimbus]

Yeah I mostly use Debian for servers or when I need to set up a quick VM.

Go-to choice for something stable that's pretty much it

[upper prairie]

but I feel like openSUSE doesn't get as much love as it should

and I will preach that until I die

plus the community is amazing

I don't think I could say the same for Arch, honestly

[light blaze]

Arch's discord server community are fucking insanely nice

[upper prairie]

We must share different experiences

[light blaze]

sorry if I'm not allowed to swear but about 5 people there all together helped me install arch for the first time while explaining literally every bit to me and teaching me so much

they stayed with me on the chat for 6 hours

they helped me 6 hours straight without a break

[light blaze]

yeah experiences differ

[warped nimbus]

I don't believe it's fair to make generalisations. There are good and bad people in every community. You just need to find the good guys.

[fickle granite]

ymmv

[light blaze]

they said it was a rare occasion and the support I received was a 1 in a million

they just felt like helping that moment

[light blaze]

absolutely right

[upper prairie]

idk, always been harder for me to find an Arch community that wasn't so uh... elitist

[warped nimbus]

Well you're talking with two Arch users and neither of us came off as elitist I'd like to think. So we do exist :D

[light blaze]

yeah

but I am by any means not good enough to assist with anything that is arch related

well I got to go, it was a really fun chat and I learned quite a lot

I'll look through many new particular options I've been suggested here when I uninstall ubuntu

including new ubuntu flavors

[mortal knoll]

gentoo communities are better

[mortal knoll]

Feeling nutty rn

[dapper musk]

may i ask why? as far as ik there is nothing special about it. It is very similar in feature set to RHEL while having smaller support both community wise since it is less popular and enterprise wise since redhat is bigger company than suse. in addition to that at least from my experience they zypper is slower than dnf(this might be related to my location tho) and YAST the suposedly main selling point have awful interface in TUI mode(you need to constantly spam tab) + it is slow(loading? times). Why would someone use it over RHEL/CENTOS/Rocky or other clones?

[trail sapphire]

i would have added "for servers and Fedora for desktop" or similar, close to the end of your message 🙂

[dapper musk]

while fedora is quite good distro which makes good use of things like zram, thermald and pipewire however i personaly would't use it for desktop since wayland on nvidia is pain and i would't trust BTRFS with my data(multi disk is still considered experimental) also they are pushing flatpak imo awful technology which is compleatly unusable on my 11 year old thinkpad(secondary computer). Also since fedora relies on systemd boot times are awful compared to something like runit while they do not nessecarly matter on servers and desktops they do on laptops since hibernation in linux cannot described as working(tbh it is't used by any OS anymore) and "sleep mode" uses a lot of power while being idle turning off laptop is the only way to conserve battery and well waiting 30s while you want to check something fast is't ideal.

[trail sapphire]

did you mean "suspend" instead of "sleep"?
also, have you tried "hybrid sleep"?
flatpak is kind of like snap and i don't care for any of them, but you don't need to use them either

[fickle granite]

@wispy ingot what exactly are you trying to protect your VPS from?

unless you're rich, I imagine the biggest threat is script kiddies; in which case, what you've already done should be fine

I've run a couple of EC2 hosts for years with nothing fancier than that, and (as far as I know! 🙂 ) have never been hacked

[wispy ingot]

oh cool, I see. Nope, I was just planning on making my Discord bot public and I'd just like to ensure I begin the right way - prevent any skid from getting into my VPS later down the road.

[fickle granite]

I wouldn't stress over it; ssh is good and linux is good; you sound like you know what you're doing

[somber ermine]

hey guys I have a question

how can I change filenames

with regex

I want to change log1.txt to mylog1-file.txt

with linux ofc

[trail sapphire]

use mmv if you have it or can install it
it's not really regex, but maybe enough for what you want to do

[light gorge]

How ppl usually remap keys for MacOS? Caps to ctr on long press, caps to esc on short press. Anything else?

[olive jungle]

I'm having a problem with this:
bash: /home/vi/.bashrc: line 147: syntax error near unexpected token `(' bash: /home/vi/.bashrc: line 147: `export DISPLAY=\$(grep nameserver /etc/resolv.conf | awk '{print \$2; exit}'):0'Can I borrow a fresh pair of eyes?

[upper prairie]

My guess would be because of \$

[olive jungle]

I don't need the dollars?

[upper prairie]

Sure, but why would you need \?

[olive jungle]

https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FslInstallation/Windows#WSL_2_Changes_.28_provisional_.29

I'm going by these instructions.

 echo "export LIBGL_ALWAYS_INDIRECT=1" >> ~/.bashrc```

this was copied exactly, so that's why I have the \

[upper prairie]

ah, I think I see

in your .bashrc, remove those backslashes

the purpose of them is to prevent the $() and $2 from being evaluated

like when you run the echo, I mean

but they're not intended to be in your .bashrc

[olive jungle]

export DISPLAY=$(grep nameserver /etc/resolv.conf | awk '{print $2; exit}'):0

so this should work?

[upper prairie]

If I had to guess, yes

[olive jungle]

just a sec

well, bash starts without an error now. i had hoped that removing the error would allow fsleyes to work but it's still saying it's unable to access X Display

[upper prairie]

echo $DISPLAY, see what it says

[olive jungle]

localhost:0.0

i could change that to something else

i guess

[upper prairie]

Well

Then another question... Are you on Windows 11?

[olive jungle]

I hate networking tho it always feels hard to me but it's usually just my anxiety

windows 10

[upper prairie]

So then that might be why

"Unable to access the X Display" is presumably because you don't have WSLg

[olive jungle]

the steps i'm following are for WSL 2

[upper prairie]

which is a Windows 11 thing

WSL without WSLg doesn't have an X server

[olive jungle]

oh it doesn't?

shoot

[upper prairie]

Pretty sure, anyways
