unix

[summer trail]

What do you mean by "unix-interpretable"?

[ebon dove]

I mean, is there a distinction between the set of all characters available in unix-like systems and the set of all characters that have a unicode representation?

[summer trail]

Hm. Well, Unix filesystem paths don't need to be valid UTF-8 strings, which might sort of be what you're asking about

Other than that, I guess it might depend on what you mean by "available"...

[ebon dove]

I'll read up on UTF-8, that'll get me started. Thank you!

[formal schooner]

file paths on unix-like systems are blobs of bytes with no particular file encoding.

unicode is an abstract system of representing text as a sequence of "code points", so it's not really relevant to things that are blobs of bytes (nor is there a clearly defined idea of a "character" in unicode).

there are several systems for representing unicode in a string of bytes. these are called encodings. the most preferred encoding for general use is UTF-8, but you'll also see UTF-16 and its ancestor UCS-2 occasionally (notably in Javascript), and internally some systems (like Python) use UTF-32 because it has certain desirable characteristics. in 2023, most webpages and "text" files on your computer should be encoded in UTF-8. ideally the same is true for file paths, but there's no strict requirement that it be true. this is what godlygeek was talking about.

see here for an interesting discussion https://dwheeler.com/essays/fixing-unix-linux-filenames.html

[ebon dove]

These are important clarifications, thank you very much! I'll get on reading the link you linked.

[south fossil]

I don't know what "unix-interpretable" characters are, but I think unicode can represent any character including 8-bit ASCII

[formal schooner]

unicode is intended to be able to represent all of human writing yes

it's basically 1 number per "code point", but the notion of a visible character is more like what unicode calls an "extended grapheme cluster"

and yes the lowest numbers correspond exactly with ascii, and very closely (but not exactly) with latin-1, iso-8859-1, windows cp-1252, et al

that is, ascii character 1 is unicode code point 1, ascii character 2 is unicode code point 2, etc. the "basic latin" block of unicode is the set of ascii characters.

[summer trail]

the lowest 256 code points of Unicode correspond exactly to latin-1 (aka iso-8859-1)

the "basic latin" block of Unicode comes directly from ISO-8859-1

!e print(all(chr(i) == bytes([i]).decode("latin1") for i in range(256)))

[shy yoke]

@summer trail :white_check_mark: Your 3.11 eval job has completed with return code 0.

True

[formal schooner]

i wasn't sure about that, thanks for clarifying

maybe windows cp-1252 is the one that's slightly incompatible with unicode? i can't remember

[summer trail]

yeah, cp-1252 overlaps a lot with latin1, but not entirely

[hallow herald]

Binbows uses ucs2

but claims that its utf16

hello

I run ubuntu on Oracle vmware

today had an error while starting: failed to send host log message

can anyone help me?

[ember quiver]

I googled it for you. https://www.remembertheusers.com/2022/08/0853-failed-to-send-host-log-message.html

[knotty saddle]

I'm new to programming

[ember quiver]

But you'll find lots of other people suggesting lots of other things so just keep at it

[drowsy saffron]

Well found nothing fancy

[south fossil]

oracle vmware? what's that?

[fallow tusk]

VMWare - a Virtual Machine controller (a la virtualbox)

I get the "failed to send host log message" all the time; it doesn't appear to mean much - nothing nasty has happened whenever I get it, at least ;)

[ember quiver]

VirtualBox isn't VMware, they are competitors. It was clear that you probably meant VirtualBox.

But anyway, like I said, there are plenty of potential solutions to that warning a web search away.

[fallow tusk]

I didn't say they were. I said "a la virtualbox" - i.e. in the same mannter that virtualbox is

Yeah, I'm just trying the blacklist option

[south fossil]

Yes but what is "oracle vmware"?

[fallow tusk]

VMWare is made by Oracle

fwiw, it seems there's an issue in the vmwgfx driver - there was an addition to send a log message from the driver to (afaict) the hypervisor. But virtualbox (and presumably VMWare) don't have anywhere to receive that message. Hence the error.

I had misunderstood dowcet's post as saying that the vmwgfx driver wasn't needed if you were using VMSVGA. This isn't the case - it is needed. After putting the blacklist in place, and then updating initramfs to exclude the module, the machine rebooted, but I couldn't use X (oddly I could get the DM selector up, but then got a blank screen with no WM)

Here's the virtualbox "bug" repport on it: https://www.virtualbox.org/ticket/19168#comment:4

[drowsy saffron]

I cannot run the linux

thats the problem

[south fossil]

ARE YOU SURE?

[fallow tusk]

Yes

[fallow tusk]

I don't think that's the problem, you should be able to treat it as a warning rather than an error.

When you see that, are you able to get to another tty (ctrl-alt-F2, for tty2, say)?

[south fossil]

Oracle is a company, and VMware is a company. Those are two different companies, and AFAIK one didn't bought another.

[fallow tusk]

Ah - Oracle provides a VMWare service

Interesting. I'll swear I've seen Oracle branding for more than just a VMWare hosting service. (Which is also what I assume the OP has seen)

[spark mulch]

VirtualBox is by Oracle

[fickle granite]

Broadcom owns (or intends to own) VMware; Oracle is separate

[hallow herald]

Does unix have no such thing as global (OS wide) (named) mutex?

[fickle granite]

not sure. If such a thing existed, it'd almost certainly live in the file system.

I actually don't remember exactly what a "mutex" is but perhaps POSIX semaphores would help you do whatever you need -- https://www.gnu.org/software/libc/manual/html_node/Semaphores.html

[fallow tusk]

Yep anything like that would be under POSIX…

Hi, don't know if it's the right server to me asking in, but i've got two tarballs, control.tar.gz and data.tar.gz and would like to make it into a debian file. It used to be in a .deb file but i extracted it to do some edits on the control file, but now i can't figure out how to make it into a deb file again

[spark mulch]

I think this should work:

echo 2.0 > debian-binary
ar r outputfile.deb debian-binary control.tar.gz data.tar.gz

But if at all possible, try to build it with dpkg-deb instead.

[fallow tusk]

I don't know what the input to dpkg-deb is, but you can just concatenate two (unzipped) tarballs directly

[royal bone]

Hi guys,
Got a problem.
Scenario -
I'm trying to install python 3.8 or higher to goDaddy shared hosting.
Got some nice stuff in this blog - https://www.godaddy.com/resources/skills/how-to-install-and-configure-python-on-a-hosted-server
The 3.4 version is working fine.
But when I try to compile the 3.8.
There is always an pip SSL error.
Here is a link which I was following to resolve the issue - https://jhooq.com/pip-install-connection-error/

I have tried everything in the blog.
Tried asking ChatGPT too.
The answer was to add --with-ssl at the time of configure.
It throws an error that this flag is not defined.
I'm stuck with it.
Any help will be appreciated.

as this is unix channel, i think asking here abt qtile config file and discussing abt it is legal

as qtile doesnt use script lang, but python.

Whichever you prefer

oh, i didnt even knew they had a disxord server

thank u :3

[main olive]

for display it doeant really matter, but if i had to choose between the two, i would def pick out kde

both are super bloated, but at least kde have smth going on for it

[fallow tusk]

I definitely feel that Gnome is heavier/clunkier/slower than KDE. That is just a feeling from trying it a few times in the past, though. I haven't installed Gnome in a while.

[echo tinsel]

This is more of a linux question but I am working on a python project with a shell script to streamline the dev process.

My project consists of a virtual env and the source files. I want the script to activate the venv, cd in the source files and then run the program. Once the code is done I want to exit. I've been trying to create a subshell with (), but once the script exists the directory is still changed and the venv is still active. I often ctrl-c out of the program so a quick cd back and deactivate command won't cut it here.

I have a simple script

#!/bin/bash

start() (
    . .venv/bin/activate;
    cd src;
    python main.py $@;
)

start

How can I make sure the changes I make in the start function are not carried into my terminal?

[ember quiver]

I'm not sure I follow exactly what you're trying to do but seems like using subprocess in Python instead of Bash could make this fairly simple?

[echo tinsel]

I want the venv to not be active and the directory to be src/.. once the python script has exited. Currently the terminal has the changes that were done within the script

[wise forge]

u can run scripts from venv without its activation
venv/bin/python3 script_file.py 😉

[wise forge]

This looks like monstrocity 🙈 u a doing smth wrong. Why did u write it
Are you trying to solve your Path path discovery problems?

[normal dagger]

https://github.com/sde1000/python-wayland/blob/master/wayland/client.py#L62
so Python Wayland doesn't have any dependencies. it communicates through the wire protocol, my only question is how the socket knows what to do? (XDG_RUNTIME_DIR)?
same with libei(emulated input for wayland)

[shy yoke]

wayland/client.py line 62

xdg_runtime_dir = os.getenv('XDG_RUNTIME_DIR')```

[normal dagger]

its literally sending a bunch of byte streams.

The server starts a libeis context (which can be integrated with flatpak
portals) and uses the libeis file descriptor to monitor for
client requests.

ah god
im really stupid.

in python-wayland

Doesn't wrap libwayland, instead reads Wayland protocol description XML files and speaks the Wayland wire protocol directly.

is it something that automatically going to work under the hood? but then why libeis is needed and sometimes its not(python-wayland)?

I just don't understand how a bunch of byte streams make any sense to a socket which is 'XDG_RUNTIME_DIR', I can't believe that the only requirement is to use wayland as a display server.

[echo tinsel]

yes i want to run my program within my project folder but have my code in the src dir within it. i didn’t think about the first message tho lmao

[wise forge]

path_to_venv/bin/python3 src/main.py 😉
and no hacks are required.

[echo tinsel]

issue there is my paths are incorrect. i remember changing the pythonpath env but that had an affect that i don’t remember and i’m not at my desk

[wise forge]

i recommend running as path_to_venv/bin/python3 -m src.main though (and having __init__.py file in src folder)
then u can use absolute imports like

from src import asd

and importing any other folder u have in project

[wise forge]

u must never change pythonpath env. this is path to doom

[echo tinsel]

it’s in a .env file in my project and it works with that

[wise forge]

😬 rethink your life choices. this is really bad approach in python

messing up pythonpath leads to only suffering

[formal schooner]

i set pythonpath in my projects but i know exactly what i'm doing and it's largely a workaround for institutional inertia

personally i'd rather python -m build and copy the wheel into my docker image, but instead of copy the src/ dir and set pythonpath to src

it's not that bad in general if you have a well-organized project and you don't want to involve pip or wheels

[wise forge]

Well... But, if u start setting multiple paths into pythonpath, then all hell breaks loose for sure 😁

[formal schooner]

its possible, but again requires discipline

e.g. we have scripts/ and source/, the former being for things that we only use in the repo for dev stuff, and the latter being the app code

both are added to pythonpath, then we add tests/ (via the pytest option, not in the env var) to run the tests

so scripts/generate_test_data/ is a module with several files and we can invoke it as python -m generate_test_data

that said, it's the kind of thing where if you have to ask whether you need it, you don't need it or shouldn't try to use it

what you should almost certainly never do @echo tinsel is set it and forget where you set it

it's like PATH itself, it's your responsibility to manage it

[echo tinsel]

oh yeah you can just put it in a .env file within the head of the repo (for the purpose i had)

[wise forge]

why will not having as all of them as just packages 🙈 (with __init__.py inside)
and running code as python3 -m script.generate_test_data

then u can sanely importing in absolute paths code between all of those folders

[formal schooner]

i don't want scripts/__init__.py, some of the scripts aren't python

(it works even without the init file, as a namespace package, but imo that's just goofy)

[wise forge]

why not, it is just to make scripts launchable, and having proper accesability to source code via absolute paths

it is not like it is going to be bundled into package deployed. there is a choice to select what is deployed

[formal schooner]

partly because i don't think it's any better than setting PYTHONPATH, and partly because it's abusing the namespace package functionality to do a job that it's not meant to do

obviously this is all kind of ad-hoc and you should use whatever you like. but this works well for me and i don't dislike it

[wise forge]

but without PYTHONPATH u can have your project working in dev env and unit testable without any additional problems
or at least with less problems

it serves more dev friendly configuration discovery for other devs (or to you in a year later 😄 )

[formal schooner]

the source code is still in src/ like you'd expect

and we tend to wrap things in a shell script or makefile anyway, that's just the house style

[wise forge]

i'll draw a card of person that setups project configuartions, automating, CI code and deploys apps
I would honestly hate such additional problems
there is enough problems to deal as it is in any project

[formal schooner]

i do some of that, but never for other people's projects

i'm sure things would be different in a bigger organization

[wise forge]

Speaking of awesome settings. Pydantic has settings module 😄

from . import types
from pydantic import BaseModel
from pydantic_settings import BaseSettings, SettingsConfigDict

class SettingsB(BaseModel):
    debug: bool = False
    celery_redis_host: types.RedisHostAddress = types.RedisHostAddress("redis://localhost:6379/0")
    discord_channel_health: types.DiscordWebhookUrl
    discord_channel_news: types.DiscordWebhookUrl
    telegram_bot_token: types.TelegramBotToken
    telegram_channel_health: types.TelegramChannelID
    telegram_channel_news: types.TelegramChannelID
    log_level: types.LogLevel = types.LogLev.DEBUG
    test_mode: bool

class Settings(BaseSettings, SettingsB):
    model_config = SettingsConfigDict(env_prefix='', case_sensitive=False,)

i love it.

[formal schooner]

e.g. another option would be to make it all pip installable so you could pip install -e . and get all scripts, app code, etc. in your enironment under a single namespace package

yeah we use that extensively

pydantic has certainly grown on me, despite several annoyances

why split settings into two classes, instead of inheriting from BaseSettings directly?

i haven't used pydantic 2.0 yet so i'm not sure if that's a 2.0 idiom

[wise forge]

probably should remove such complication 😄 not really having major impact though

[formal schooner]

fair enough

the 2.0 migration is going to hurt a bit. we have a lot of small apps using BaseSettings, several of which have custom validators and other hooks into pydantic behavior

[wise forge]

i thought there will be time i will need Settings without ability to get settings from env. (apperently i did not)

[formal schooner]

you can disable it, at least in 1.0 you could with MySettings(_env_file=None, **kwargs) or something like that

obviously not pretty

[tropic wasp]

Does android count as unix

[shrewd stratus]

unix-like probably, since it uses a modified Linux kernel

[fickle granite]

what does "count as" mean?

[tropic wasp]

Does it count as a unix operating system

[fickle granite]

I still don't know what "count as" means.

why are you asking?

[tropic wasp]

Is it

A

Unix

Operating

System

Or

A

Unix

Like

Operating

System

Do

You

Understand

Now?

[south fossil]

Andoid it not a UNIX

However, Android is based on the Linux kernel, which is a Unix-like operating system

[fickle granite]

no I don't understand

since I don't know what those terms mean, precisely, and neither do you

it is and it isn't.

is MacOS Unix?

is Windows with WSL Unix?

until you define what "Unix' means to you, it's impossible to answer.

Does it have to have the famous hierarchical file system? (I actually don't know if Android does.)

Does it have to be multi-user?

Does it have to have a shell and a C compiler?

Does it have to share code with the original implementation from Bell Labs?

[tropic wasp]

Yes

It does

[fickle granite]

ah now we're getting somewhere

like I said: I honestly don't know if Android does.

my point is: "is it unix" is impossibly vague; but those questions I listed above are at least answerable.

[tropic wasp]

I understand

[fickle granite]

so come up with a list of questions of your own, that define what "unix" means to you, and see what the answers are for Android.

[summer trail]

Android is Linux. If you consider Linux to be Unix, then Android is as well.

[rotund girder]

Ok, now I know to avoid Flatpak! I will try to steer clear of Wayland today and hopefully I can get my setup working again.

My vnc is, not happy. Used tiger vnc previously but after upgrade to ubuntu 22 it has been fighting against me. Anyone else with vnc experience/opinions?

[ember quiver]

"fighting against me" is pretty vague so your guess is better than ours. If the problem is server side, check the logs for errors. (Not sure if the client has a log or not)

[humble falcon]

My understanding is that Android once had the linux kernel, but it has been changed so much over time that it really can't be considered "linux"

[fickle granite]

still has the linux kernel, but I tend to agree with the rest of what you said

https://en.wikipedia.org/wiki/Ship_of_Theseus

[spark mulch]

What about Linux has been changed in Android? It literally ships an (AFAIK unmodified) kernel, in my case it's 4.19.269 (Settings->About phone->Android version).

[ember quiver]

The Linux Foundation maintains the Linux kernel. Google maintains the Android kernel. I have not looked at the source code for either but I would be shocked if they were identical.

[fallow tusk]

They add patches that are "relevant to Android", and then they have some stuff on top, it seems. https://source.android.com/docs/core/architecture/kernel

Looks like the GKI builds are a cut-down version of an LTS kernel which then allows modular additions for vendor-specific drivers and the like

[summer trail]

Considering they continuously merge Linux kernel changes into Android, there's no Ship of Theseus situation. You could use the Ship of Theseus to argue about whether macOS is really BSD, but not whether Android is really Linux. It's not a hard fork, they continue to contribute to Linux kernel development, and continue to pick up new kernel versions and new modules.

[fickle granite]

well, I meant they've only got the kernel, and little or none of the userspace -- to me, Linux is more than just the kernel.

[summer trail]

sounds like you're referring to Stallman's "GNU+Linux" 😂

[lavish storm]

[jaunty pine]

“Unix” has two meanings:

• A legal trademark
• An informal term for a set of traditions about how an OS is supposed to work.

[rotund girder]

I'm trying to figure out what to put in my xstartup, but if I put something incorrect it seems like I botk some state and have to reboot my machine to get back to a clean slate.
I'm using tigervnc. I will see if I can find some logs

[fickle granite]

Oddly appropriate essay
https://utcc.utoronto.ca/~cks/space/blog/unix/UnixTechnologyAndIdea

[fallow tusk]

You shouldn't need to reboot - at least not if you're using something like startx to get your GUI up and running (after which you can migrate to a DM which handles that at boot). You can use a second tty if the first locks out because of changes to the GUI setup.

[idle knot]

Android's lower-level components are Unix-like. Being Unix-like is inheriting features and functionalities from the original Unix operating system. Android's user space is not Unix.

[rotund girder]

What do you mean? Migrate?

[fallow tusk]

As in don't use the DM until you've got it working without. first

[jaunty pine]

I have my regular default Ubuntu 22.04 setup with gnome and Wayland (I think) working. And I'm happy with that. Can I get that same environment working over vnc?

[fallow tusk]

Probably. I have managed to cobble together a tigervnc setup that seemed to work, but it took me a lot of wrangling and reading of online howtos - several of which I'm not sure were necessary :|

Let me see - I did start doing my own write-up of what I did to get my company PDE to talk nicely over VNC

[rotund girder]

That would be greatly helpful, thank you.

[fallow tusk]

Looks like https://www.tecmint.com/install-vnc-server-on-rhel-8/ was the guide I used to get mine up and running. I know it's for RHEL, but all the same things should apply where it's not RHEL-specific

There are some changes I make to ~/.vnc/xstartup, too - to specify which user gets which port :5=user to map port 5905 to be used by user user (remote port is 5900 + the display identifier used here)

Aha. Looks like the session (DE) is selected by adding a session=... line to /etc/tigervnc/vncserver-config-defaults. I'm sure there's more, but my notes are more just a command history atm - I was trying to flesh them out, but ran out of impetus ;)

[rotund girder]

Thanks! Could you share your xstartup script?

[ebon dove]

how is the loopback device (localhost/127.0.0.1) virtualized? is it treated by the OS as a standalone I/O device?

[shrewd stratus]

IIRC, the loopback address is special cased in the kernel's IP stack

as in, it's not treated as an I/O device at all

any packets to that address are routed directly

i think you just need to set PS1?
do echo $PS1 in your debain one and copy and paste that and set PS1 accordingly in your WSL ubuntu 🤷

also ubuntu's default is the same as debain as far as i know (for regular user), it's just that root's bash is "unthemed", you will get the same experience if you make a regular user

howwwww do i make a regular user?

[warped nimbus]

Without using third party libraries in Python, what's a nice way, if any, to read a file in another namespace?

In my case, I'd like to get the mac address of a network interface in another namespace. I'd like to avoid using a subprocess if possible, but my current solution is a subprocess that runs ip netns exec ... cat /sys/...

[wise forge]

What is namespace

[warped nimbus]

A network namespace

[south fossil]

he seems to refer to network namespaces in Linux, dunno how it relates to files

[warped nimbus]

As in the namespaces feature in linux

[south fossil]

and how it relates to files?

[warped nimbus]

I can get the mac address of an interface by reading a file e.g. /sys/class/net/eth0/address

But if my python process is not executed in the same network ns as the interface for which I need the mac address, the file won't exist. My python script needs to manage interfaces in different namespaces so executing the entire script in a different ns is not an option.

[south fossil]

Namespaces was created for isolation.
If you are running Python process in isolation, you cannot do that. Unless you are superuser or unless you have another process being run outside of isolation.

[warped nimbus]

Hmm yeah I suppose I have to use a subprocess

[south fossil]

All forked processes will be isolated as well.

[warped nimbus]

If I use something like python-nsenter even that seems like it requires a subprocess within the context

Maybe not. I'm not too familiar with how setns propagates. If could just setns and then open a file that would be great.

But there's not a convenient way to call setns to begin with. Unless I use ctypes or third party lib

[compact grove]

How do I add the process ID to the string format? sh ./venv/bin/python main.py force \ 1> >(ts "[%F %T]" >> cron/stdout.log) \ 2> >(ts "[%F %T]" >> cron/stderr.log) & I'm using ts "[%F %T]" >> cron/stdout.log to prepend timestamps to every stdout line, i.e. py print("Starting up a new instance.") produces: ```
[2023-09-02 05:30:07] Starting up a new instance.

I would _like_ to include the process ID in this format, like: ```
[1509][2023-09-02 05:30:07] Starting up a new instance.
``` where `1509` is the process ID

how do I do that? I've tried sh ./venv/bin/python main.py force \ 1> >(ts "${$$} [%F %T]" >> cron/stdout.log) \ 2> >(ts "${$$} [%F %T]" >> cron/stderr.log) & but I get bash: ${$$}: bad substitution

oh, it's just "[$$][%F %T]"

[rotund girder]

I just thought of a cool/boring visualization I would like to do. A partial filetree where the folders with the most git activity is listed, and the less touched files are filtered - so that it all fits on one page. So similar to git-heat-map but perhaps as a compare/weighting function to [broot] (https://github.com/Canop/broot)
What do you think, does it exist?

[formal schooner]

i think the version with braces is ${$} i.e. the parameter is named $

[compact grove]

ah, that makes sense

[barren temple]

change your shell to zsh and install oh-my-zsh 😄

oh... it was old messages i was seeing.

nothing new

[formal schooner]

blech, i am a long time zsh user but those plugin frameworks are nothing but trouble

[barren temple]

but it gets you a nice looking shell

😄

with no trouble

[formal schooner]

yeah but its easy to add a "plugin" manually, you source the .plugin.zsh and add its functions/ dir to fpath

it's two lines of code!

ofc you get error handling etc

its just that its too tempting to add a ton of poorly maintained plugins and you get a slow messy shell config

and at least as of when i last used omz, it was very poorly curated

[main olive]

Hi, i have a old surface pro tablet still works great but it has a corruption in one block of memory.i know which address it is.is there a way to prevent os to access that block?

[south fossil]

no

@main olive Well, for Windows you can limit maximum available memory via msconfig params. For Linux kernel you can do a similar thing booting it with mem= param. But you should be lucky, and the failed memory addresses should be at the end not at the beginning. And in the first place you should somehow modify those params on a failing hardware.

[main olive]

I found out windows has bcdedit tool to prevent acess memory page

Trying it

[south fossil]

msconfig is the same

[main olive]

But this time i only block 4kb

4kb page of memory

I have only 1 corrupt memory

Address*

Sometimes i have bsod

[main olive]

Should be removed last 3 digit

I will make bashscript to automate this because this solution is not permanent

I need to fetch memory list from memtest86 report

Python Expert Programming has chapter regarding parallelism 🤔
may be there is more detailed regarding parallelism

Otherwise there is always an option to read official docs https://docs.python.org/3/library/subprocess.html

[main olive]

Is anyone taking a Unix class in college?

[ember quiver]

No. But if you have a question you should just ask

i downloaded the whole official docs with httrack, those and the pep-s are probably the best source of information about anything python related

[main olive]

[humble falcon]

Can the same driver be compiled for different minor releases of the kernel?

[rotund girder]

[dire glacier]

@primal sierra

sorry for the mention

so how can i do that

hello?

so the problem is im not able to download linux

[fallow tusk]

"not able to"?

[dire glacier]

ye

cuz of the boot menu

its good that someone answered

xd

[fallow tusk]

You should already be in an operating system in order to download anything…

[dire glacier]

ugh wdym

i want to dual boot

[fallow tusk]

"boot into Linux", did you mean?

[dire glacier]

nah nah

i want just to dual boot

but install linux first

because i dont know how

linux didnt want to install when i tried

[fallow tusk]

Right, so you need some sort of installation media…

[dire glacier]

tell me what do you mean so i can tell you if i have done it or nah

[fallow tusk]

How did you try to install Linux?

[dire glacier]

i installed it on a usb which was 4gb but it was mint linux and it was able to be downloaded in it by the use of rufus app and then i tried to open boot manager on the old laptop to open the usb but it didnt recognize it so i opened the boot menu to enable the legacy thing and secure boot as my old laptop is legacy boot thing but the weird thing i didnt find them and till now i dont know what to do like most of my boot menu is empty (i dont know how it is a boot menu XD)

[fallow tusk]

So when you put the USB stick in, and boot the PC, you don't see it booting from the USB stick?

[dire glacier]

i didnt even see the usb stick name appearing or any

i checked if its recognized on windows and it was

[fallow tusk]

What does happen when you boot with the USB stick in?

[dire glacier]

nothing it just shows me the normal list of boot menu and i choose the boot manager to see the usb but all i see is a hardware and cd and both when i clicked them boot me to windows

[fallow tusk]

OK, you may need to enable booting from USB in the BIOS

[dire glacier]

didnt find it

fr my bios is weird

i have been trying all the solutions on yt for hours and i didnt find any

the bios is empty

like it has few options

which are useless

is it possible to boot the usb from windows?

cuz this bios wont help me ig

[fallow tusk]

No, you'll have to find the option in your BIOS to boot from a USB, or write a CD and boot from that - but that would mean it's a very old BIOS.

Some BIOS have an "advanced" mode that you need to enable…but that should be an obvious option

[dire glacier]

i5 2nd gen 4gb ram (I added 2gb )

i just wanna revive it for normal use and linux would be enough for that

i tried to search about the name of the laptop and its bios and got no video

[dire glacier]

fr its empty i dont know where to find that

[fallow tusk]

What BIOS is it? (I'm not sure how much further I can help, tbh, but that may point me towards some details of what you might need to do)

[dire glacier]

i dont know but i know the device name

will that help?

[fallow tusk]

Probably not. Doesn't the BIOS screen give a name?

The motherboard details could help, I guess

[dire glacier]

okay wait lemme search the motherboard name

where can i find the full name of the laptop

and its motherboard name?

[fallow tusk]

In Windows you should find that in the system info

[dire glacier]

i opened the dxdiag thing and it says the bios name is

InsydeH20 Version 03.61.0 1F. 42

[dire glacier]

its name from dxdiag the bios

[fallow tusk]

https://answers.microsoft.com/en-us/windows/forum/all/how-do-i-configure-insydeh20-setup-utility-to/5b1a2952-c953-4b86-b7a4-52fe6d962a3d

That seems to show how to get to enabling a USB boot option

[dire glacier]

i dont have the info of legacy bios

and secure boot

thats the issue im facing

is the only chance is to boot from windows?

the problem is its the same bios as mine

:/

[lapis cloud]

when I installed linux I recall having trouble with UEFI vs legacy boot

iirc the issue was that windows10, which I dualbooted with, only supports UEFI, which was somehow nontrivial to install linux mint with?

[dire glacier]

ye my device is the opposite actually so thats why im facing a problem but i dont know what to do actually

[wise forge]

use Rufus

it makes USB automatically friendly to all those systems 🙂

[dire glacier]

did that

[wise forge]

¯_(ツ)_/¯

[fallow tusk]

oh? Most modern distros expect UEFI, I thought. it's usually a lack of UEFI support in the hard/firmware that causes issues (although I do recall Mint being odd) But the Insyde website suggests the BIOS should support UEFI

[dire glacier]

ye

is it possible to just boot from windows

or any of that

[fallow tusk]

Have you tried using a different USB port?

[lapis cloud]

I no longer remember what the issue was, maybe I had to disable secure boot

[dire glacier]

nah

[fallow tusk]

(one of the other suggestions from that link)

Yeah, disabling secure boot is probably a necessity

[dire glacier]

i dont even have that option and thats why im confused

[fallow tusk]

(I have to switch between secure and non-secure for my dualboot setup)

[dire glacier]

is this laptop a mad one or sth?

[fallow tusk]

If you don't have the option it probably means it's not an issue

[dire glacier]

but ofc there is a solution and i believe in that

[fallow tusk]

(i.e it's not capable of secure boot, anyway)

I'm sure you're just missing something in the BIOS settings…but not being able to poke around in it myself sort of limits how much more help I can be (plus it's bed time!)

[dire glacier]

ik your tried to help as good as possible and i appreciate that

your a good man

maybe i will try to see more vids or sth xd

Gn

[fallow tusk]

You're more likely to find answers on things like stagkoverflow or hardware-specific bulletin boards, I imagine

[dire glacier]

okay ima see that then

[dire glacier]

yo again

i did it man!

this laptop is so buggy in bios and so old

so thats why you keep dragging the usb option up to the top cuz there is no usb enable or disable

and thats it you try to open bios manager again

i kept trying for so long xd

[finite crater]

disabling secure boot part 1 of why I don't dual boot anymore. Part 2 is the ease of virtualization.

[dire glacier]

thats just an old laptop anyways so ye

i wanted to see if it will be fast on it

but tbh linux was doing good well on it

the linux mint

[fickle granite]

@woven trench you can tell by looking. ls -l includes a header line

Anyone well versed in pop o.s and Msi?

[ember quiver]

Don't ask to ask, just ask

[acoustic stag]

You are correct, thank you for the advice. I solved the issue.

I couldn't figure out why security features on my new motherboard were locked. I figured out the issue was not having an admin password set. Once it was set, the secure boot could be disabled. Installation of Linux was possible.

whats so bad about running fastapi with sudo (besides that the packages are annoyingly installed in a non normal place) when you want it to be https and read .pem files? im not a linux pro, is there a safer way? I don't want to give up on running fastapi as https, I'm thinking there's something smarter to do with the file permissions

it's pem files certbot put in /etc/letsencrypt

[spark mulch]

The easiest way would be having a reverse proxy (e.g. nginx, Caddy) that runs on port 443 which then hands the traffic to FastAPI running on some higher port. You can also delegate the https stuff to the proxy then.

[main olive]

oh, so I can configure nginx itself to have the pem files? ill have to try that I think that might fix another problem I'm having with needing to expose the fastapi port

[spark mulch]

Even better, you can configure it to get the certificates for you. With Caddy that is even the default.

[wooden mural]

hey im using freebsd machine and when entering command df i get 1k blocks but i want to change it to 512 byte blocks. anyone know how i can do that?

[fickle granite]

df --help should show you the various options

failing that, try man df

I don't have a freeBSD machine handy so I can't do it for you

you might also have "GNU df" available as gdf. If you do, it does the same stuff, but with fancier options.

[wooden mural]

DF(1) FreeBSD General Commands Manual DF(1)

NAME
df – display free disk space

SYNOPSIS
df [--libxo] [-b | -g | -H | -h | -k | -m | -P] [-acilnT] [-,] [-t type]
[file | filesystem ...]

DESCRIPTION
The df utility displays statistics about the amount of free disk space on
the specified mounted file system or on the file system of which file is
a part. By default block counts are displayed with an assumed block size
of 512 bytes. If neither a file or a file system operand is specified,
statistics for all mounted file systems are displayed (subject to the -t
option below).

 The following options are available:

 --libxo
         Generate output via libxo(3) in a selection of different human
         and machine readable formats.  See xo_parse_args(3) for details
         on command line arguments.

i searched it up

[fickle granite]

well I'm not gonna read it for you 🙂

[wooden mural]

ik but i couldnt find a command that would change the bytes

[fickle granite]

so it says it shows 512-byte blocks by default.

Maybe your df is actually an alias to df -k or something.

[wooden mural]

its 1k blocks

[fickle granite]

I'm not following you.

[wooden mural]

i want to change it to 512 byte blocks

[fickle granite]

yes I understand.

[wooden mural]

but i cant find the command to do that

[fickle granite]

yes, I understsand.

[wooden mural]

only to write a shell script

but i dont want to write script tho

[fickle granite]

try /bin/df instead of just df; see if it does anything different.

[wooden mural]

ok

its same thing

[fickle granite]

that's quite puzzling, since the man page clearly says

By default block counts are displayed with an assumed block size of 512 bytes
Are you sure it's displaying 1k blocks?

[wooden mural]

yes

[fickle granite]

no offense, but ... how do you know?

[wooden mural]

thats why i want to change it to 512 bytes. because thats what it outputs lol

[fickle granite]

yes I understand that

[wooden mural]

i found this online df -k | awk 'NR == 1 { print $1, "512-byte blocks" } NR > 1 { printf "%-20s %10d\n", $1, $2 * 2 }'

[fickle granite]

I don't understand why you're showing me that

[wooden mural]

but i think theres a much easier way to do it

ok neverming

[fickle granite]

yeah that awk stuff looks like it's just multiplying the output by two, which is reasonable

Can I ask for help here with a shell script I'm trying to run that has a problem?

[fickle granite]

don't see why not

[elfin hearth]

Can anyone here help me figure out a problem with a shell script I have? I have a script to download subtitles for a movie but it doesn't work for some reason because the path has a space and special characters in it. I have no idea why and I've been unable to figure it out for a long time: https://paste.pythondiscord.com/4CTQ

I get this output ```sh
$ bash ./opensubtitles-dl.sh -n "Jarhead 2005" -l eng -o "/media/jb/T7/Movies/movies/Jarhead (2005)/Subtitles/eng"

the command it echoes /usr/bin/curl https://dl.opensubtitles.org/en/download/sub/{6073089} -o /media/jb/T7/Movies/movies/Jarhead\ \(2005\)/Subtitles works perfectly fine when run in the terminal

this function specifically contains the problem with curl ```sh
download_subtitle() {
# $1: subtitle id
while read -r id; do
echo $_OUTPUT_FOLDER
echo "$_CURL" "$_DOWNLOAD_URL{$id}" -o "$_OUTPUT_FOLDER/${id}.zip"

    "$_CURL" "$_DOWNLOAD_URL{$id}" -o "$_OUTPUT_FOLDER/${id}.zip"
    "$_UNZIP" -o "$_OUTPUT_FOLDER/${id}.zip" -x "*.nfo" -d "$_OUTPUT_FOLDER"
    rm -f "$_OUTPUT_FOLDER/${id}.zip"
done <<< "$1"

}

it seems that it's interpreting the path as two different paths when it's the same except there's a space in the path but it's escaped so I don't understand why it thinks there are two

[elfin hearth]

I fixed it, I added a bunch of eval commands. I don't think it's the cleanest solution but it works. I'd still like an explanation for me to understand why the initial function above didn't work? sh eval $(echo "$_CURL" "$_DOWNLOAD_URL{$id}" -o "$_OUTPUT_FOLDER/${id}.zip") eval $(echo "$_UNZIP" -o "$_OUTPUT_FOLDER/${id}.zip" -x "*.nfo" -d "$_OUTPUT_FOLDER") eval $(echo rm -f "$_OUTPUT_FOLDER/${id}.zip") }

[ember quiver]

All I can say is that on the rare occasion that I do bash scripting, I just try to keep my paths clean without spaces and such because escaping properly is often frustrating

[fickle granite]

all I can say is that: if my bash script grows to more than maybe five lines, I rewrite it in python

[formal schooner]

The error message makes it look like a whitespace problem, look at where it's trying to write to

You forgot to quote a parameter expansion somewhere

Although I don't see an actual place where that would occur

The evals should definitely not be necessary

Try using set -eux

-eu for safety, -x for a trace of executed commands

You do forget to quote the command substitution in set_args but that's not likely to be a problem

However i think you're confused about how escaping works

x='a\ b' ; $x expands to a\ and b

that's why the eval fixed your problem... the slash escape only works when the shell commands are parsed

same is true in python strings, you can't write "\" + "n" and expect to get a linefeed character... that's kind of what you're doing here

actually i might be totally wrong about that... huh

no nvm i was right

Has anyone encountered this bug when running an Ubuntu ISO from USB? The ISO runs but there is no mouse cursor, although i can move it and click

it's actually one instance of the shell behaving exactly like any other programming language

[fickle granite]

🤷

[summer trail]

x='a\ b' ; $x expands to a\ and b

I'd say that's a weird shell idiosyncracy. Off the top of my head, I can't think of any other language that has anything analogous to shell's "word splitting", where a variable's value is parsed as a string at the point where it's interpolated to decide how many strings it should produce. I can't think of another language off the top of my head where a string regularly gets implicitly treated as an array of strings without any explicit call to eval or the like

[willow bloom]

I am trying to install Linux
But it will show me input output error 5

[ember quiver]

I googled it for you, but as the comments here explain, we can't give you the solution without more context: https://askubuntu.com/questions/1333763/error-5-input-output-error

This is not the place to go further, look for support based on the specific distro you're trying to install

[willow bloom]

I used same distro ubantu before this
But I accidentally format whole ssd drive
When I am trying to reinstall it then it occurs this kind of error

[ember quiver]

Based on a quick read through the comments on the link I provided it sounds like a problem either with the target drive or possibly your installation disk. You'll need to troubleshoot. I would probably start with fsck or another disk check utility

[formal schooner]

fair, but the way the escaping works i think is consistent with other programming languages

the way i like to think of shell script is that every command is actually just a string, and every usage of a variable is actually a string interpolation into that string

i believe tcl has similar quirks, but i haven't used it myself

[fallow tusk]

I was going to mention tcl...but it's so long since I used it. I think it's also the first time I really encountered multi-level string interpolation, so possibly tainted memories!

[cold plank]

quick question, is it possible to encrypt a password for example on python and decrypt on powershell?

[wise forge]

everything is possible :/ although easiest choice to do that will be just running in powershell python3 -c "python code to descrpt password; print(result)" 😅

[cold plank]

The thing is im on a linux vm right where i have a python script which also contains a powershell script with in it. I am sending this powershell script to another vm through pywinrm. Within this powershell script i am passing the credentials containing the password.

I need to make sure that the password is encrypted before passing it through

[wise forge]

I am confused 😕🤔

What is this target deployment vm

What is its OS

[cold plank]

its a windows

target is windows source is linux

so in windows os, im going to be running a powershell script

which will be sent through the python script i have on the linux system

[wise forge]

Are u admin of this widows, and capable to do everything there?

What is your real intended goal with those encrypting shenanigans

[cold plank]

i need those credentials to access a server on the windows machine

[buoyant cedar]

You rang?

[cold plank]

The main problem is to pass those credentials encrypted

[wise forge]

Can't u just put not encrypted credentials and send it?

What stops u from doing that

[cold plank]

becauese then its not encrypted

and its not secure

if i send the password through on the powershell script

if not is there a secure string thing in unix?

[wise forge]

Your pywinrm should be already creating encrypted connection

What is the point to encrypt twice 🙂

And what is the point to encrypt it in this situation, if u a going to decrypt it at the end anyway

So... with transit already encrypted, it looks like already enough of encryptions to me

[ember quiver]

If you want to apply AES encryption in Python/Linux and then decrypt in PowerShell, it should be fairly trivial to do so. Have you tried it?

[quaint whale]

hi

[wise forge]

dowset offered good enough option. basically you wish anything that can serve as a symmetric encryption. AES can work for it

although it could be more funny to use smth asymmetric 😅 good old RSA can work too

symetric is going to be more simple for you

[wise forge]

https://pypi.org/project/cryptography/ probably something to use from cryptography library for example

>>> from cryptography.fernet import Fernet
>>> # Put this somewhere safe!
>>> key = Fernet.generate_key()
>>> f = Fernet(key)
>>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
>>> token

[south verge]

@rotund girder any recommendations?

[rotund girder]

for distro?

[south verge]

I have tried ubuntu 22 with snap
And linux mint

[rotund girder]

I'm using Ubuntu at home as well at the office, it works

I'm enjoying unix + nvim as my programming environment

[south verge]

But i never really thought of making it my primary OS .
Now i have been using wsl for like 8 months and can't think of using windows again

[south verge]

I use vim extension for vscode

[rotund girder]

If I had the time and energy, and there actually existed good documentation, I would go for NixOS distro.

[south verge]

But i only use it bcz my keyboard doesn't have up/ down keys(accidentally bought the 60% varient)

[rotund girder]

vscode is popular 🙂

[south verge]

Never heard of it

I'll look into that one

[rotund girder]

It might be good to really good with a simpler distro first (I'm guessing now that NixOS is difficult because it's quite a bit special)

(but it's also popular so most application might be easy to install and use anyway! 🙂 )

[south verge]

So they made an OS just to for package manager?

[rotund girder]

the package manager Nix and NixOS were both created in 2003

so I guess they were co-created

[south verge]

Yes but y not just use it as a package manager

Y does it require an entire os

Maybe I'll use it as a server

Bcz it looks like it'll be really helpful to setup

As a server

[rotund girder]

You can probably use another distro + Nix, not sure how much of the cake you get, 50%? 90?%

[south verge]

Have you ever tried arch linux

[rotund girder]

nope, but that's probavbly really good to learn linux

[south verge]

I need an os which is easier for development and very minimal

But i am afraid of arch😂
Don't wana spend too much time on learning new things

Also security issues(don't know how to setup proper firewalls and stuff)

[rotund girder]

I just know terminal/shell/prompt/git/vim, some stuff about files/symlinks/pipes/ssh/X but MANY holes

But the holes are fillable with man!

Builtin help is the best!

[rotund girder]

right, I know nothing about it

[south verge]

I'll try it in vm before installing ig

Probably will go with ubuntu

[rotund girder]

time to sleep.

Ubuntu sounds like a good idea

however, the snap application provided by the snap package manager have some problems, if you are lucky you might not notice it

[south verge]

Hopefully i won't 😆
(P.S : i am not lucky)

[rotund girder]

nighty 🙂

haha

[south verge]

Damn no wonder this channel is ded

[rotund girder]

Haha whut? 😂

[south verge]

I have spent like last 7 hours configuring bspwm
There was no option to set 2 monitors(like i can set it up but it always extends display and not add extra space)

If that makes sense

[rotund girder]

Oh, you didn't get that automatically? Never heard of bsp 😶

I guess you googled a lot already. (https://reddit.com/r/bspwm/s/2XyBTZAdwR)
Sorry I can't be of help, I've only used default Ubuntu windows manager (gnome+X/Wayland) and xfce.

[south verge]

This is for when u disconnect something different.
Well now i installed i3wm
Who da fk is naming these 😂

It is better for setting up display

Just need discord now😭

And then setup my coding environment 💀

Ok it is working me think

[rotund girder]

I would advise you to version control your dotfiles immediately

[south verge]

Y r there so many pakage managers

[rotund girder]

Don't ask me, it's crazy

[south verge]

Too late(if u r refering to my github work files)

Most of them r in python so what could go wrong

[rotund girder]

Apt, Flatpak, packman, nix, ...

Huh? 😳

Github work files. No I mean stuff like ~/.bashrc, ~/.gitconfig,...

Configuration files for your environment

[south verge]

ohh ok never worked wiith them before

[rotund girder]

Dotfile because it starts with a dot. They are considered "hidden". You want see them unless you ls -a to list all files.

Those two I mentioned are settings for bash and git. Which configuration you have depends on what programs you use I guess 🙂

[south verge]

alright i will

what you think about neovim

previously i was using vscode with vim extension

[fallow tusk]

You only need to deal with different package managers if you use different distros, generally. Although flatpak and <that other one> throw a bit of a spanner in the works.

What do I think about neovim? I think it's a text editor… :)

[south verge]

like isit a good text editor if you want to touch mouse
or iit is hyped?

[fallow tusk]

(much the same I think of VSCode/Codium/etc)

There's a fair learning curve, but if you've already learned some of the vi keybindings, you will be fine

[south verge]

great

time to set it up

and i wounder what happend to that tiling windows

[rotund girder]

I use neovim and love it!

I have not used any of the neovim "distros" (kickstarter, lazyvim, lunar-, astro-,...)

This is my small nvim config: https://github.com/kaddkaka/dotfiles/blob/main/dot_config/nvim/small.vim

bruuuuuuuuuuuuuuuuuuuuhhhhhhhhhhhh

urs is lder then me

we are actually same age

python was same pretty much even 24 years ago ?

[wise forge]

definitely not. It got better 😅

really liking direction of python... evolution in terms of typing

if u are feeling kinky, u can go almost full C# in python now

[south verge]

how can i make mine like this we both are using i3wm

[south verge]

i meant like the syntax

i have never before tried reading py2.x

[south verge]

rate this someone ??

my github is like 2 (1.5)years old

[wise forge]

this is sad times of not existing typing. in fact i think typing may be did not exist until 3.5
as well as not existing dataclasses or pydantic

[south verge]

yeah something like

no one uses it though

i went thorugh my code
literally coded that moduel in my sleep every type was wrong

🤣 but python didn't care (bcz it understands us)

How do I install pip in WSL?

Already got python installed but tried using the docs for installing pip with linux, has not worked.

[fallow tusk]

Ubuntu WSL? Probably apt install python3-pip

[wise forge]

The Best answer, u don't
Install
sudo apt update
sudo apt install -y python3-venv

And create python3 -m venv venv in desired project folders

source venv/bin/activate

And use pip from there

[hexed arrow]

Right, but what is the install for pip?

[wise forge]

It will be auto installed inside venv

[hexed arrow]

What commands?

[wise forge]

Marked above

[hexed arrow]

[hexed arrow]

Perfect, thank you

[wise forge]

Beware, moving between folders venv is not possible.

[hexed arrow]

What do I put here, the name of the venv or the directory?

[wise forge]

Name of venv

[hexed arrow]

And then do I put this in as is?

Or replace source with file path for venv or the name?

[wise forge]

source is command, don't replace

[wise forge]

pip freeze > constraints.txt to freeze deps versions.
Put main deps into requirements.txt (without versions or with minimum sign version or whatever)
Install as pip install -r requirements.txt -c constraints.txt from activated venv

Put venv into .gitignore

Regenerate constraints when wishing 😁

Very manualish and simple default. If wishing automated, learn using poetry

[hexed arrow]

What do I use to deactivate the venv - so it is no longer running, not delete it though.

[wise forge]

deactivate 😅

[hexed arrow]

Thought so, just wanted to be sure

[wise forge]

😉 u could install eventually btw specific python3.8-venv python3.10-venv packages (u need to install specific python first though)
and create venvs as python3.10 -m venv venv or as python3.8 -m venv venv
Thus having ability to use different python versions for different projects

[hexed arrow]

Oh, I'm not that into it 😅

[wise forge]

python3 is just some your system default python3 (don't ever delete it or make changes to it. u will break OS then)
(that is why i discouraged installing pip into system python, to avoid ever deleting smth that your OS relies upon to function)

[hexed arrow]

Just trying to start using Ubuntu more and having a more organised workspace

[wise forge]

just nice to know options 😅

i can't dev until i found out

1. how to use different language versions
2. how to install packages and where they are stored (and how to make your own library)

• also how to record which packages u use and having ability to install them again after repository cloning
• how to delete specific packages

3. how to setup using unit testing framework

• and probably with ability how to mock stuff in this language
• how to run specific unit tests via CLI
• how to turn on visual debug during unit tests

4. how to write CI to make deployment of app
5. and of course how to start application

• preferably again with ability to turn on visual debug during the run

[hexed arrow]

Yeh, I am probably intermediate with Python, I believe I have a few highly advanced topics still to go through but I know more than enough to get around in the language - just struggling with the whole managing my workspace thing.

I am actually moving onto C# which is interesting to say the least.

[hexed arrow]

Is it possible to have a separate WSL terminals running separately? I.e., they are two different instances?

[wise forge]

i use pure Linux
i go with Konsole from Kubuntu 22.04 LTS for terminal multiplexor

people tend to like also Terminator as terminal multiplexor

install Terminator 😅 or Konsole

Not sure if u will be able to make it working in WSL though

WSL is not a real Linux

not a guarantee u will be able to even install it there

[hexed arrow]

That's what I thought

I believe I may put Linux on my old PC

[fallow tusk]

You should be able to run multiple WSL instances, but I'm unsure if you can run multiple of the same wsl distro (e.g. ubuntu and kali, but maybe not two ubuntu)

[fickle granite]

?

why would that be?

[main olive]

i ahve a cloud computing question

have*

i'm running Ubuntu in a cloud instance

and after uploading my Python script and trying to run it nothing happens.. what gives?

[ember quiver]

So you're logged in via SSH and entering `python3 myscript.py' and then literally nothing happens? You're still connected, there's no error message and you can't type anything?

Without knowing anything about what your script looks like, I would tend to blame that and not the VM

[main olive]

it must have been an error during upload. got it working. now i am trying to figure out how to view png's from command line

any recommended packages? tried eye of gnome, desktop-file-utils..

[ember quiver]

Over SSH? Not possible. You'd need to serve the file so you can open it locally

[main olive]

apparently i have display and that also fails

so i am saving the png on the instance and trying to open it as i would any ubuntu command line tool

its just not showing up, i wonder if it is firefox blocking a 'popup..'

[ember quiver]

Did you say this is a cloud based server? Running a command remotely over SSH isn't going to launch Firefox or anything else on your local machine

[ember quiver]

Unless you really want to go through the trouble of setting up a remote x session, just download the file and open it

[main olive]

i'll try that thanks

worked

ty

[south verge]

what is a terminal?

like i think i misunderstod what terminal actually is
i changed my terminal from xfce to alacrity and it changed themes for other windows??

[fallow tusk]

That doesn't sound normal. Alacritty is just a terminal so its settings should only affect the terminal (and only alacritty)

[south verge]

is arch somehow using terminal configs for other window themes?

is that possible

[fallow tusk]

That wouldn't be Arch, but Xfce (if that's your DE)

You should be able to see the settings from the desktop menu, iirc (I can't recall how you get to them in Xfce)

https://wiki.archlinux.org/title/Xfce (section 3)

[south verge]

thanks

[opal basin]

Dislocker problem...

I accidentally shutdown when decrying BitLocker on windows 💀

Can dislocker helps?

[formal schooner]

Xfce doesn't do that, but you might have changed some global xfce settings thinking they only applied to the terminal

hello can anyone help me with ubuntu 22.04 two finger fast scrolling problem ?

https://askubuntu.com/questions/1413750/how-to-change-2-finger-touchpad-scroll-speed-on-ubuntu-22-04

this solution is not working

[south verge]

This is a unix channel y are we talking linux only here

[fallow tusk]

"unix" in the general sense, not "Unix" in the specific sense.

[rotund girder]

It's the speed a problem I'm all applications? Otherwise specific applications might have settings for scroll speed.

[south verge]

how can i change python version on my endevoros(arch) to 3.10 or 3.9 it is currently at 3.11

[lavish storm]

use pipx/pyenv and friends (not gonna do an exhaustive list)

don't u even think about changing your system python's version

[south verge]

that's what i was thinking

i sometimes get these urges lel

i guess i'll just install it beside 3.11

[humble falcon]

pyenv install 3.10, then pyenv global 3.10

[harsh herald]

if i do 2 finger scroll from touchpad it super fast in all app i want to make slow scrolling in all app when i scroll in vs code it fast and in firefox it fast in every app fast !
if i scroll from mouse it normal i cant find settings to slow down !

https://bbs.archlinux.org/viewtopic.php?id=277224

i have ubuntu install and do u know anything about sway ?

can it help me ?

[lunar viper]

Probably not the channel to ask, but does any ubuntu user here know how can I screenshare audio without using a third party client?

[humble falcon]

Depends on your desktop environment but there should be a touchpad setting where you adjust scroll speed

[harsh herald]

only have this setting its ubuntu 22.04

its gnome desktop enviroment

touchpad speed (range input) only change the speed of cursor in screen not scroll i need controller or low speed in 2 finger scrolling !

[ember quiver]

I'm not sure if you simply mean "stream audio" or "screenshare with audio" but either way it would require a client of some kind. Are you asking how to write one in Python?

[brazen jewel]

hey

someone here use ubuntu

?

a lot of people don't like it

and it's not very popular in countrys like united states

australia

maybe in london

[fallow tusk]

https://ubuntu.com/desktop/statistics seems to suggest that your statement's quite incorrect

As does https://truelist.co/blog/linux-statistics/

[shrewd stratus]

do you… have a question?

[fallow tusk]

I like how "London" gets the status of a country on par with the US and Australia ;)

[kindred basin]

Darn, didn't know that London even left Britain to become an independent nation.

[kindred basin]

Are you able to share your screen? Just no audio? Are you using the web Discord client or the installed one?

[lunar viper]

Installed one

Screen share works just fine, is just audio not getting streamed

[ember quiver]

Apparently it's complicated: https://www.reddit.com/r/linux_gaming/comments/t0bkw7/psa_discord_screensharing_with_sound_is_possible/

[humble falcon]

Sometimes I forget discord can be used for stuff other than text messages lol

[rotund girder]

Ubuntu popular in London? That's a weird statement 😂

[wise forge]

linux desktop usage is in general around 2% in the world

somehow did not get stuck with regular people. Windows is more dominating just because they have at minimum agressive company to have it preinstalled everywhere

yet, Linux is perfection for developers

especially for developers in web development, backend and DevOps engineering

OS that has everything working natively for your servers

[wise forge]

I personally enjoy Kubuntu 22.04 LTS. it is purrfect

inbuilt multi terminal

comfortable GUI with normal desktop and windows

good working Docker in its native lightweight way. access to all web infrastructure instruments

all dev tools are installed in one or few command lines from apt/snap/wget/deb whatever

[feral night]

Why do people always say "this" distro or "that" distro is better and then show a bunch of theamed screenshots without explaining the underlying difference... was my understanding you could add theams of almost any kind to your desktop environment and its still the same linux... I know "l" ubuntu is "lite" in apps but its just ubuntu... same as mint etc etc.

Can't imagine that "k" is any different ?

[lavish storm]

the ubuntu prefixes indicate the core DE in use, no?

xubuntu uses xfce
lubuntu uses lxqt
kubuntu uses KDE etc

they just change how the interface looks but not how you manage packages for example

[feral night]

yer so at the core the sane os and on top interchangeable desktop environments that are glorified theams. so in my mind no different really.

[lavish storm]

within the scope of ubuntu derivatives, yes

[kindred basin]

Isn’t Kubuntu’s KDE maintained separately or something

Might be thinking of KDE Neon

Gnome is great though

[lunar viper]

Maybe its skill issue by my part but I've been trying to give it a shot and it's been nothing but problems. I think it wont ever stick with people until most things work out of the box without much trouble.

The ubuntu software/app store, cant remember the name rn, also has many issues so console is kinda the only way of doings things

And normal user wont do that

[wise forge]

well, that's kind of the point. Things work with less effort and out of the box for me in Linux
After getting used to Linux... i remember only in nightmares GUI crashing installers of Windows that tell no errors

in Linux... everything is friendly to do from console

GUI is... very optional for most of stuff

that makes stuff automatable, easy to record as dev instructions into git repo README, or automating to run from CI. We just need to record commands to run 😅

[lunar viper]

I guess being used to helps hahaha

I've just been having nightmares with seting everything up without errors everywhere

[wise forge]

not sure what u tried to setup.

[lunar viper]

Its not like theres is smt in particular

[wise forge]

i just use Kubuntu, which has everything configured for me out of the box.
Few things to install via apt/snap/deb and i am good to go

[lunar viper]

But more of the constant google search "error why"

And the fact that im not versed in the os

I guess im just to used too windows

[wise forge]

i used windows for most of my life until i turned 25 😅 including working as windows system administrator

but then i started to work as backend dev/DevOps engineer... and linux just became better (removed need to use VMs in order to access all web tech)

[lunar viper]

Hahaha

Switching to linux made appreciate more windows actually. I never expected that to be the outcome of this little dive of mine

Still gonna be using it, because its smt i want to learn

[wise forge]

i like that in Linux i am indeed admin 😅

once u learned what should not be done to break OS

u enjoy freedom to do ANYTHING

in windows... you are never really admin (illustrated picture above). Even if u are admin, your OS is still forbidding things, any random program can restrict you access :/

[lunar viper]

I love the customization linux provides

[wise forge]

i enjoy being free 🤗 and being sure i am having no trackers or weird processes in background that take 50% of my hardware resources for strange activities

[lunar viper]

I havent had the need to be that much of an admin yet

[lunar viper]

Yeah thats a good point

But my problem with linux is more related to compatibility

Like the discord screenshare example i posted a few messages back

[wise forge]

weird. probably some not linux friendly laptop?

or u use some weird program for doing that

[kindred basin]

I thought that was an old bug

Forgot how to resolve it

[formal schooner]

i'm not an ubuntu fan but i've definitely found my home in KDE

[wind cypress]

Please how can I fix this?
https://paste.pythondiscord.com/JRMA

[wise forge]

https://media.tenor.com/_BiwWBWhYucAAAAd/what-huh.gif

No OS, how came you up to this situation

plus, pipenv is kind of deprecated, use poetry 😅

[wind cypress]

No OS?

[wise forge]

we have no idea what is your operational system, what are previous steps u used to achieve this situation

[wind cypress]

Ubuntu 20.04, I was following https://docs.modmail.dev/installation/local-hosting-vps/ubuntu and got the error from python3.10 -m pip install pipenv

[wise forge]

is it real Ubuntu 22.04 intalled to your disk, or pseudo ubuntu installed in WSL?

[wind cypress]

Ubuntu 20.04 blank (64-bit) on VPS

[wise forge]

okay. i think you are crashing your main python system i think

python3.10 in ubuntu22.04 is main python used

u tried to install python3.10 on top of it

not sure if your OS is even still working correctly at this point

[wind cypress]

Nope, python3 --version
Python 3.8.10

[wise forge]

oh. it is ubuntu 20.04. okay it is 3.8 all right

u could have used 22.04 verison, it has python 3.10 out of the box

and saving yourself some headache then

otherwise u can continue trying to install python3.10 🤔 but do u need it if u can just switch OS?

[wise forge]

anyway, i have no idea what is this error. never really encountered in using venv
try install python3.10-venv

and create python3.10-venv -m venv venv

source .venv/bin/activate

and then install pipenv from there

could be better

u have some weird broken python installation 🤔 may be venv will help to fix it

otherwise just switch to 22.04. it will have already correct python installed, thus eliminating posilibity of errors at this step

[tardy stream]

has anyone done anything quite so crazy as to get python running inside wine?

I've been trying for several hours, and while python runs alright, pip seems to fail to install

I've used the wenv package, and found that ktinker isn't included with that installation, which I need

[wise forge]

why would u do it? 🤔

isn't python compilable fine as it is?

[tardy stream]

playing a game through proton, trying to install a python plugin for said game

python plugin uses heaps of windows dlls

[wise forge]

nasty 😅 i prefer just to use windows at this point with dual boot

[tardy stream]

basically, doing my darnedest to not dual-boot

yeah XD I'm probably gonna wind up there, but doing what I can to avoid it haha

I've no idea why pip fails to install tho, and the error isn't showing up on google haha

[wise forge]

as a silly alternative i tried to run Windows in VM at my linux with forwarded volumes
but i did not able to make videocard working for windows inside :/

You know...

i have a strong good solution how to have Windows i think

without sacrificing my Linux exp

i should just utilize my laptop for Windows and share files over samba or smth from main PC 😅

[tardy stream]

I was wondering if you were gonna say use WSL and mount your linux partition inside it XD

[wise forge]

samba is pretty good to run Windows friendly accessable filesystem

[wise forge]

i thought to say it, it is some sort of a solution, but remains hell of unsafe due to whole still being windows (which i usually pirate so it is doubled as unsafe)

[tardy stream]

XD

[wise forge]

going to try WSL next time out of fun. i heard WSL2 runs full linux inside

[tardy stream]

I've heard there's a way to remove the watermark without pirating actually, so I may go that route XD

yeah wsl2 is full linux kernel

[wise forge]

still Samba i find very attractive path

because... i don't sacritice my already configured dev env in linux

i just extend it with external windows compiler accessing it over samba

and optionally CI runners with windows

Going to have Linux dev env first solution then with Windows compatibility 😅

Hmm, if i will be not using Videocard, using Windows in VM with forwarded volumes could be enough for that

for least amount of headache and extra hardware usage

i like virt-manager to use for VMs

it does its job, and i got used to it already

well, except Videocards. that i did not get how to configure

Samba with extra laptop is good because i get 100% of windows working for sure without any setup headache. At the cost of extra hardware 😅

[tardy stream]

just in case someone's able to help with the python in wine thing: https://paste.pythondiscord.com/RHGQ

that's my tracelog for wine failing to install pip

steps to reproduce:

1. create a new wineprefix
2. download python 64-bit windows installer
3. WINEPREFIX=prefix wine python-3.x-amd64.exe
4. breaks upon trying to install pip

[wise forge]

not very reproducable. Consider using docker wine
https://hub.docker.com/r/scottyhardy/docker-wine/
and building your solution with Dockerfile from there

then it will 100% reporoducable to exact same situation

may be even saving resulting code to git repo 😅

i could bet u can utilize wget to keep everything as single Dockerfile though

[wise forge]

ENTRYPOINT ["/usr/bin/entrypoint"]

stuff like that it will be
with docker build --tag test . in current folder with file Dockerfile above to build those instructions

it will make 100% reproducability more or less

[tardy stream]

thanks! I'll see if I can get that working. Who knows, maybe it'll just work and this'll be my solution haha

[wise forge]

going to be helpful quicker to debug it too 😅 since at any time u can change one command of instruction to another one
and it will be possible to rerun-rebuild it like the deleted thing was never installed

everything remains comletely erasable without polluting system

faster feedback

Docker Deep Dive book is great if u wish to dive into this tool more in a structured way (people manage to use it without learning stuff though)

every added line with RUN or smth else in Dockerfile is cached as another layer of an image. every layer/line is a savepoint for an image

The password for the next level is stored somewhere on the server and has all of the following properties:

owned by user bandit7
owned by group bandit6
33 bytes in size

Commands you may need to solve this level
my answer is find / -user bandit7 -group bandit6 -size 33c why not workng

[ember quiver]

Not sure that's possible, and you're probably approaching the problem the wrong way... You can use a bind mount to make a host folder accessible, and then attach to the container to move files. Or you can just edit inside the container without a bind mount, if it has an editor

But this generally defeats the purpose of containerization. You should probably just build the container the way you need it.

[formal schooner]

what do you mean "not working"? what's happening that differs from what you expect?

[wise forge]

docker run -v /host_path:/container_path image_name
first path before : is your host path
second path after : is any container path

u can utilize relative path with docker run -v $(pwd)/folder_name:/container_path image_name

if u use docker-compose, declaring volumes is easier and can use . for relative path

u need to recreate container in order to bind volumes 😉

[formal schooner]

was support for . added recently?

[wise forge]

in docker-compose/docker compose? it was available long time ago? for years.
I don't even know when it was not supported (it was available already in docker compose 1.* versions)

volumes:
  ./data:/container_path

in theory it should

[formal schooner]

oh you're right! i thought for some reason i had to put $PWD in my compose file 🤔

Is there a unix-y way to run a program at given intervals, eg every hour? My current idea is just to have a time.sleep in an infinite loop but I'd rather have the program not running at all when it doesn't need to

[lavish storm]

cronjob probably?

run X at every Y units of time and it makes me instantly think of cronjobs

though it's not exactly the same as running a job that takes X minutes, and then running it again exactly an hour later

[wise forge]

Cron job is common for that
Although for turning programs on and off it is common using systemd
Not sure if we can utilize cron with systemd at the same time

[humble falcon]

Thanks, I'll check out cron jobs. I can just make the program turn itself off when the job is done

[wise forge]

For web applications in python for more programmatic control and observability, common to go for Celery Beat though
Celery Flower can be used for monitoring

And there is cloud cheap option using Event Bridge with cron rule onto AWS lambda
(This option makes paying only for when program is running, but not for idle time)

[humble falcon]

I have a home server set up so I don't need aws, thanks for the info though

[wise forge]

Celery Beat is still an option though then 🙂

Cron is simpler by magnitudes of course

[lavish storm]

for home servers cronjobs will do nicely 😄

i use it to sync mirrors, handy dandy

[humble falcon]

When would one use one vs the other?

[wise forge]

If u write many thousands code lines program, with unit testing and etc for long term quality, and u plan to deploy it within your own infra. Best is celery.
(Good if u write smth related to web apps, backend, rest APIs)
(Code scales well to run a lot of different periodic tasks)

If u just need one command to run every hour, for stuff u aren't going really to write code for... Cron will work too (and like it is not related to web apps)
(Ideal for single command to run of smth)

[humble falcon]

Sounds like cron is best for me then, thanks!

[wise forge]

I personally use cron to have auto restart of my Minecraft server every day.
Cron goes to necessary folder during 2AM UTC and runs docker-compose restart for me 😊

[lavish storm]

yah for me i write shell scripts for syncing mirrors/logging and run it through cron

[humble falcon]

On this one, I'm grabbing data from an api, seeing if there's changes since the last pull, and sending an alert to my phone if there is

[wise forge]

Cron is good for lazy stuff at your own home projects. For servers that aren't going to be ever updated probably

[wise forge]

Ergh... Not really good cron usage then. I think.
While TRUE, time sleep hour would have worked better for simplicity.

It would have allowed u utilizing shared memory of app for simple, pure in memory application logic

(Assuming it is for home projects)

We can do it with cron too, but keeping stuff stateless is very advantageous default

Your program would have been able comparing status with previous one already in memory

[lavish storm]

How does the API deal with data diffs? I don't think it's desirable to do it directly with cron (not that you can anyway)

[humble falcon]

I'd like to write the incoming data to a db if there's a change and also to take snapshots of the data every week or so, so I think this way makes sense. Might also make a webapp to display the data on a local site, depends on how lazy I feel lol

[lavish storm]

for example, mirrors provide "lastsynced" or "lastupdated" with unix time on it to compare

[ember quiver]

Sounds like a minimum viable product would be a cron job that reads a file, calls the API, and overwrites the file if changed. But if you want to store history then a SQLite DB would be best. Either way, cron would work fine

[humble falcon]

Yeah sqlite is what I have in mind, thanks

[kindred basin]

By the way, systemd timers are also great (as a substitute for cron) and I've been using them for a while now.

[neat jasper]

how much documentaion do we really need to read before im elegable to ask a qustion

[ember quiver]

All of it

[neat jasper]

lol. have anyone done that? it seems like it but the ironic thing is, there are gaps. so how does a person know, when to actually ask a question?

I think more people today will ask discord questions like. "how do i for loop ?" and actually get "ohh your poor thing let me help you with that ....."

im from the 90s. you had to read the doc that was actually made from the developer. and you know how piss poor they can be.

no google

now there is so much of it and its getting better, but man, its an equally same but different challenge.

[lavish storm]

you can just ask the question, and say that in the process you've referred to X and Y docs to no avail

for example: I'm trying to do X, i've looked up library A's docs that does this, but i don't think it's adequate for my use case---there's also B I'ved checked out but it seems to lack validation and issues are stale

and that'd be good enough for me

[neat jasper]

im refering to the stackabuse community. the discord community is very good but people ask the same thing again and again here that eventually it will be more like stack overflow.

[lavish storm]

ah that

that thing

I'm glad I'm no part of it

Don't even have an account and I have it blocked so it doesn't show up on my results

[neat jasper]

wow that is extreme but i salute you 🫡 .

Oh unix channel. Is Linux UNIX?

Im voting No

[lavish storm]

on unix or unix-like systems such as Linux or MacOS.
it's fine i guess

[neat jasper]

I know what UNIX is and i get that this channel is unixish. Im just asking the actual question is Linux UNIX or not ?

I think it has diverged into a Non unix thing that is now its own thing that is Linux .

[lavish storm]

nomenclature-wise linux stands for linux is not unix

[neat jasper]

I think you mean GNU which is Gnu is not Unix. but linux is a diritive of mimix which was linus version of mimix ?

[shrewd stratus]

Linux is Unix*-like*

it's not a certified Unix like some BSDs and macOS are
