@reef sluice

[reef sluice]

Ys

I did try q

[misty yew]

ctrl + c?

ctrl + d?

[reef sluice]

Wait lemme see

Yes it workedd

😉😉😉😎

Fron where do u got dem kali skillz g

Man i put in commands but it says command not found

[misty yew]

its basic unix skills lmao

its not specific to kali

[reef sluice]

Oh

[misty yew]

I would recommend you to get familiar with unix by using linux

[reef sluice]

I dont got a linux device

Im using nethunter through termux

[misty yew]

where are you running kali?

[misty yew]

ah I see

just use plain termux

[reef sluice]

On mobile too

[misty yew]

no need to use kali

[reef sluice]

No its because i had some mighty plans....

☠️

[misty yew]

!rule 5

[shy yoke]

Rules

5. Do not provide or request help on projects that may break laws, breach terms of services, or are malicious or inappropriate.

[reef sluice]

Lol man was so fast to pop that up

[misty yew]

I have it memorized 😎

[reef sluice]

No ofc brother would never do something like thst

🙃🙃

[misty yew]

if you want to learn just plain termux

[reef sluice]

Go on..

Im a newbie.. trying to learn python

[misty yew]

just use plain termx

install lunarvim

its usable

with that

[reef sluice]

From where did u learn this stuff

[misty yew]

u will have a learn a bit of vim bindings

[misty yew]

by trying

asking

[reef sluice]

Mmmm

[misty yew]

looking up

[reef sluice]

Courses??

[misty yew]

I didnt take any courses for this

[reef sluice]

If theres any free interactive courses pm me

FREE

[misty yew]

if u want to learn vim bindings there are plenty on youtube

[reef sluice]

ah

[misty yew]

basic unix commands are plenty too

[reef sluice]

Alright ill try then

Thx man 😇

[barren temple]

vimtutor is good for learning vim keys. It's a command

(better do it yourself, than watch someone else do, imo)

[toxic acorn]

yea vim is all muscle memory

you gotta get in the reps to get competent at it

or at least get to a point where its not getting in your way

[fallow tusk]

ESC ESC i Yeah. Until you do them subconcESC``hxsciouslyESC

[half crest]

Hi guys
I tried updating my ubuntu and when I rebooted all I got was white screen

Then I tried recovery m9de but I could login

And fixing all broken packages dkpg could connect to network in terminal

[toxic acorn]

omg I cannot tell you how many times I have ctrl-w to delete a word but instead closed the browser tab

[fallow tusk]

It's the ESC tick that often gets me - leaves the field I was typing in and clears it rather than entering it!

For me delete word is either dw or the more explicit diw

[toxic acorn]

that's interesting, I've never used esc tick before

ctrl-w is a terminal shortcut to delete one word back

[fallow tusk]

Ah, the bash prompt sequence, yes.

I assumed we were still talking vi ;)

[toxic acorn]

I mean, I use that shortcut in vim

[hexed rose]

Anyone here use Anaconda?

[real vapor]

not more explicit, it's just different

dw is delete with a motion (effectively "delete until next word")

daw and diw will delete the whole word with/without surroundings

[fallow tusk]

yeah, you're explicitly stating that extra information

[real vapor]

(tl;dr: not the same w)

(w the word motion and w the word text object)

[real vapor]

when you say this it reads as dw and diw are the same and that the latter is just more explicit

which is not true

[fallow tusk]

Yeah, I agree. I've always thought of diw/daw as being an extension of dw

[real vapor]

the i and a are pretty special

they allow stuff like ', ", (, ... as well

(for any interested reader)

ab cdef gh  ---dw->  ab cgh
    ^
ab cdef gh  --diw->  ab  gh
    ^
ab cdef gh  --daw->  ab gh
    ^

[real vapor]

fwiw, ciw, ci" and the like are quite nice if you remember to use them 😅

there is also s for sentence and p for paragraph

and t for tag, though I never use that

lots of fun stuff

[fallow tusk]

Yep, I'd been using vi for yonks before coming across the i/a versions. Now I use that quite often. I probably don't use ciw as much, although I do think I've had occasion to ;) The s and p I knew of, but they haven't entered my repertoire - probably because I seldom need them, and so seldom use them even when I could.

[fallow tusk]

Having said I don't use ciw much, I just found myself using ci" - to replace everything inside a pair of quotes. That and similar I do use a heck of a lot ;)

[real vapor]

vim is this constant learning experience

even after like a decade

@fallow tusk
I recently jotted down some notes about useful but maybe less known vim stuff, maybe you'll find something interesting.
https://algmyr.se/vim/

Or maybe you even have suggestions about things to write an article about. I for sure have stuff I don't know about vim, and probably a bunch of stuff I use without realizing it's kinda obscure

[fallow tusk]

||or more! cough||

* and # I didn't know. That's quite useful (and also works in VSCode with its own Vim emulation)

[dense kernel]

Why is my swap full, and how can I clear it?

(I'm processing some data in the background)

[real vapor]

so you've exceeded your ram by a pretty good margin to force swap usage that high

[real vapor]

wdym by clear? you want to try to force that usage from swap to ram?

I probably wouldn't do that when you're so close to the limit

[dense kernel]

How? Its only uing 69% of the RAM and 85% of the Swap rn

there is still some space

[real vapor]

13 + 2.1 = 15.1 which is kinda close to 16.5

[dense kernel]

I would like to try that, because I didnt have this issue on Windows (altough I had others), and the swap slows everything down by 100x (quite literally)

[real vapor]

you can do it by turning swap off
sudo swapoff -a
and then back on again
sudo swapon -a

but I would probably try to reduce some memory usage first

[dense kernel]

yeah thats what I need to do

[real vapor]

so that you're not hitting swap again immediately at the first spike

[dense kernel]

but as of lately I see it uses alot of swap, even when its only using like 50 - 70% of the RAM

[real vapor]

if you exceed 100% ram it will send stuff to swap

[dense kernel]

look at this shit:

I just interrupted the script but its not even clearing the SWAP (or moving it)

[real vapor]

it should theoretically be swapped back eventually as memory is actually accessed

but you can force things with swapoff/swapon

[wise forge]

there is possible to configure rules for priorities swap is supposed to be less priority

[dense kernel]

so this isnt normal, is it?

[real vapor]

but as said, try to avoid swapping in the first place 😛

swap is a crash cushion, not extra ram

[wise forge]

my swap cleared itself on its own, not noticed when.
It was full along with mem recently, almost to the top

[wise forge]

having 2 GB SWAP is kind of useless in the first place, Swap should be equal to amount of RAM or greater 😁

[real vapor]

it should clear up a bit as ram in swap is accessed

if I had to guess it's probably stuff belonging to a web browser or something, lots of caching, few accesses

[dense kernel]

yeah bro, its just the Ubuntu default

I'll try to clean up a bit the script, but I'm already doing everything in batches, weird ...

[real vapor]

looking at your ram you have really high base usage

and then some fluctuation on top

which I guess might be your batches

[dense kernel]

exactly, the fluctuation was bringing the chunk in memory (list of dictionaries) and then writing it to a parquet

[real vapor]

so I guess look into what causes the high base memory usage

[dense kernel]

the thing is that the base should be the same troughout the execution of the script, but instead it grows slowly slowly, so I'm thinking there is a memory leak somewhere

[real vapor]

if it's plain python probably not a leak per se

do you have stuff that gets added to throughout all batches?

[dense kernel]

idk what you mean by added, but I'm basically reading some data, create new data, and wrting the new data to a parquet

and I'm doing everything using Iterators/Generators both for reading, processing, and writing

but I need to double check how pyarrow handles an Iterator when its passed to pyarrow.dataset.write_dataset(data=it), cuz I suspect it might create some very large dataset with all the batches and then write it to the disk

[real vapor]

yeah, that sounds possible

[real vapor]

as in something accumulated somewhere, be it a buffer, something that should be cleared between runs but that isn't, or whatever

[main olive]

What distro is everyone using?
And is it 'unix' or more commonly 'unix like'?

[wise forge]

Everyone uses their own favourite
It is very common to use something Ubuntu/Debian based in its distro origins.
(Good choice commonly used for servers too, and Debians are most often choice for Docker images too)
(Ubuntu is based on Debian)

I can recommend my favourite Kubuntu 22.04 LTS. A bit heavy in GUI, but very nice.
Plus general GUI layout is my favourite. (KDE Plasma)
And good enough default console terminal with multi window split screen support

[wise forge]

More Unix like. Unix is its own operational system as far as I know, from which Linux derived. Unix was original source of inspiration apparently.

[fallow tusk]

Indeed, anything "Linux" is going to be "unix-like", as that was the original intent of the university project - to produce a "unix-like" operating system

I guess the other main "unix-like" group of OSes are the BSD ones. Again, I don't think they are "Unix", just "unix-like".

Ah, no, BSD is actually a UNIX (according to Wikipedia, at least), along with AIX, HP-UX , SunOS/Solaris, Xenix

[toxic acorn]

I use endeavor os

its basically arch but with a good installer and good defaults

[dapper musk]

no BSD isn’t unix it is unix derivative just like linux

unix itself was operating system developed by AT&T

and apparently wikipedia isn’t consistent with itself on this. It brings up BSD as an Unix-like on Unix-like page while categorizing is an Unix on BSD page. Either way distinction of Unix group from Unix-like is blurry at best and when people refer to Unix nowadays they mean Unix-like

[fallow tusk]

I guess the original AT&T UNIX (bought by Novell?) is no longer in use (except, perhaps, in an archaeocomputing environment - although I wouldn't be completely surprised if there's some vestigial system that still relies on it somewhere!), and all that remains are the descendants ;)

[wise forge]

I remember relatively recently we learned and used something named Unix during university.
It was for subject: Real time response systems.
Our program is heavily outdated though

It had unusual gray GUI interface that looked like from Windows 98 era or older, and taskbar on the right

[fallow tusk]

Psh. A GUI? That might have been something Solaris-y.

[wise forge]

Considering that Fortran (with on purpose compiler from 1970x years!) and Prolog were in our program too, it speaks nothing about how ancient it can be 😁

[fallow tusk]

!pypi pylog

[shy yoke]

pylog v1.1

Python implementation of Prolog features.

[fallow tusk]

}:D

[runic goblet]

.... just seeing the name "prolog" brings back memories. not good ones at that.

[dapper musk]

https://en.wikipedia.org/wiki/Motif_(software)

this perhaps?

[wise forge]

missing ugly taskbar on the right and ugly background

Found name!

it is Neutrino! QNX!

[dapper musk]

oh thats really bad lol

but i guess in real time operating system it was't their priority...

[wise forge]

more correct authentic background 😁

[wise forge]

indeed

[fallow tusk]

Oh. QNX is quite a lot more recent than UNIX, iirc.

1980s, apparently

OK. It was written for the 8088 ;)

[dapper musk]

and apparently it is still used

[fallow tusk]

Yep.

Although it was rewritten from the ground up in the 90s.

And presumably tweaked by Blackberry since then

[shrewd stratus]

Blackberry Unix 👀

[fallow tusk]

BBX :)

[main olive]

looks nice.

[main olive]

My understanding is that Unix is a licensing specification provided to OSes. One major difference between Linux and Unix distributions is that Linux is a separately packaged kernel + user space tooling, where Unix is an all in one synchronization. In that respect, BSD distros are Unix though in the respect that packages/ports are now available it could be considered Unix-like.

[main olive]

xenodm ftw

[fickle parrot]

I am having SSL Error when I try to pip install a package in venv.
I tried to run the pip install with --trusted-host pypi.org --trusted-host files.pythonhosted.org which still didn't work.
I have no issue when pip installing outside of venv. Is there something I'm missing?

I'm running ubuntu 22.04

[fickle parrot]

I think the reason was my python was installed with wrong SSL configuration

[runic goblet]

how did you get your python? did you compile it yourself?

[dapper musk]

well there is specification https://en.wikipedia.org/wiki/Single_UNIX_Specification

but according to this BSD's don't comply

[summer trail]

and there have been Unix-certified Linux distributions. https://unix.stackexchange.com/a/476945/17497

[real vapor]

idk if it's worth it for most operating systems to spend the money and time needed to certify as unix

[warm birch]

Mint vs Manjaro vs Fedora, which is best on a slow, old laptop with low ram, and which would you recommend a Linux noob?

[runic goblet]

personally i like to stick to ubuntu/debian-family in tems of distro.. (for personal use and recommendation alike)
that just leaves mint on your list, it's probably fine with an old laptop
though i prefer XFCE (so xubuntu instead of mint) if you really want to be super resource efficient while being beginner friendly

[vagrant fern]

I think your DE / WM will make the biggest impact on performance. I recently set up Linux on an old laptop with 2 GB RAM and a HDD: Debian 11 with IceWM (goal was to make it look like old Windows since the user was familar with it) runs great for its age

[wet mountain]

Hey there, to anyone who may be looking at this tired or fresh!

Been hitting my head constantly figuring out how github pull-requests work via Git or command line interface!
Kinda stuck hard right now!
If anyone could shoot me up a DM, would waste a little time of yours, I bet!

Step 1 and Step 2 have been shown in the image, Step 2 is basically me clicking on the pull request option.

Expected Behavior: Should show a box to write message for my pull request!

Do shoot me a DM, if you choose to answer to this.
Thanks have a lovely night/day!

[vagrant fern]

You can‘t open a PR because like the description says master and main have different commit histories. Your two branches need a common ancestor to be merged properly

[wet mountain]

Sorry mate, but you need to dive deeper with that explaination, for me to understand!

Tried googling a lot.
Got some keypoints-
--github recently changed master to main!
-- so i need to first put git add -M main and make that branch in my local repo as well
--after doing that confirming I am the user of the repo I am currently practicing at either by SSH or token keys or other ways!

Also rebase-ing dosen't work, neither does --allow-combined-histories something!

@vagrant fern

[vagrant fern]

if you have master locally and main is an empty branch on github and it's a mess trying to get it to work then maybe it's just simpler to just change the default branch of that repo on github to master

are there any commits on main?

[warm birch]

How exactly do WMs work? Like.. say I install Linux Mint (with Cinnamon DE).. do I just install a WM, such as i3, on top, and.. that'll work and make things better? Does the DE version matter in such a case? I mean, Linux Mint has Cinnamon, MATE and Xfce.. does it matter which version I install if I then install a WM?
P.s. I'm a total Linux noob, sry

[vagrant fern]

cinnamon comes with a WM built in

not sure about choosing each separately tbh

I just run i3

[fickle granite]

you should be able to use the package manager to swap window managers easily. I can't give you any details since I've never used Mint

[wet mountain]

Either that or could I change my local branch to main?--same name as online!

Also, coming about commits on main, I don't think so! As I made changes using CLI so was only making them on master, where master being the base branch!

@vagrant fern anyways, thanks mate!

I'll try all the solutions today and let you know!

[vernal pagoda]

Hi guys

[fast barn]

I have a log files, it might contain an error lines or not, i want to make a code that can understand each error line and print just a unique from each no need to duplicate

Example

Input file :
Leakage value 1.2 for circuit 1 is greater than the standard

1)Leakage value 0.9 for circuit 2 is greater than standard

2)Capacitance is huge in circuit 3

3)Capacitance is huge in circuit 4

4)Capacitance is huge in circuit 5

5)Capacitance is huge in circuit 6

6)High delay in circuit 7

Output: must be the unique ignoring instance information like circuit number or certain value

1. Leakage value 1.2 for circuit 1 is greater than the standard

2. Capacitance is huge in circuit 3

3. High delay in circuit 7

The log file may contain over than 10000 errors but not ,however its might be just 10 unique errors as shown in the output ,,,

Anyone can suggest a library, or a place to start from?is it possible to make code clever enough to determine these things ?

[fallow tusk]

I'd use Python, although I'm sure some combination of grep, cut, sort and the like could do it. If it is just a Python question you might be better off asking in a #1035199133436354600 channel…

Ah, I see you did…and in #algos-and-data-structs …

[wise forge]

Btw, firstly it is a classical example task belonging to #tools-and-devops

[wise forge]

Secondly, I can bet there are tools/solutions already having features to deduplicate error logs. This feature exists at least in Sentry. Datadog should be having it too

Sentry should be possible to self host

Among lightweightest self hosted ones, logging stack : Loki + Prometheus+ Grafana should be having same feature, while giving cool interface to navigate logs

Your task kind of sounds more like u need perhaps Prometheus metrics custom agent perhaps instead of real Logging

Just check Prometheus integrations, there should be python library too

[wise forge]

Thirdly, u can of course make your own tool.
In python it will be simple default libraries
Usage of generators/regex parsing if necessary. Everything pretty simple and no third party libs are required

All u need to be not dumb enough to keep it all in memory at once. Use iterators/generators to be reading files in a smarter way

[wise forge]

Fourthly, in such tasks shines the best solution made in Golang, because it is the best for such logging/monitoring tools due to small end weight result binary without dependencies. Always great to augment easily existing infrastructure
U would be able to make it on same Inbuilt libraries to read file / and some data structure to deduplicate it (if u have just ten unique records, it means just using hashmap/set in python, or map in Golang)

[fast barn]

Thank you so much sir, you put me on the road again, i really don’t know that this problem are under devops, since i work as a chip design i automate and know very well bash and linux and of curse some python, but never delt with such a problem, all the topics u mentioned was totally new to me, however i am excited to learn about it and make this script which will save me and my team lot of time,,,appreciated again

i know this is a stupid issue with my syntax.. any ideas?

[fickle granite]

you're running find twice. Is that intentional?

[fallow tusk]

Oh, the -execs are seen as belonging to the top-level find; the second one isn't for the inner find

Might need the sh -c (iirc) trick to run the inner find

[fickle granite]

don't think you should have two finds at all; it's confusing. Maybe find . -wholename '*/recup_dir.*/*.zip' -exec mv {} /home/k/recovery ';'?

[fallow tusk]

I can see the logic behind the two finds; that's not confusing. Combining them produces something that is, though :)

how you are going to override of the 4th line using sed?

[fallow tusk]

sed -i '4i line 4' filename

override or insert?

[fallow tusk]

that inserts

[tepid drift]

thanks for your help

[tepid drift]

override

[fallow tusk]

I guess that could be sed -i '4d;4i new line' filename - not sure. Moyen's suggestion using s would work, but you'd have to specify the entire line as the search pattern (^.*$) which seems a little unnecessary ;)

Hello everyone,
I have created a little python program with which you can create a beautiful readable chapters txt file (of the format "h:mm:ss YOUR_CHAPTER_TITLE") . 
Then you can use the txt file to add your chapter titles and afterwards use the script to attach it to the video. 
Keep in mind though that this program only works in Unix systems like macOS and you need FFmpeg installed on your machine. 
The github repo of the project is: https://github.com/amireza007/ChapterForVideos
There are some TODO things, available in the code such as a UI and exception handling.
I would really appreciate if you take time to test and even more if you have any comments regarding it or improvements or edits to the project. 
Thanks for your attention

I assume they only keep a few minor versions of each old version

there's files for a bunch of other minor versions though

[unkempt hamlet]

oh yep I didnt see that

thanks

any idea why there is no installer for 3.9.16

[fickle granite]

other than that, no

if you're that set on exactly that version, and no other, then build it from source

or try pyenv -- it might let you specify a version that precisely

❯ ~/.pyenv/versions/3.9.16/bin/python3 --version
Python 3.9.16

[radiant kraken]

@unkempt hamlet judging from the pattern of the last few versions, only maintenance patches get binaries, and once they're legacy (for example after 3.8.10 and 3.9.13) they get source-only security releases

oh its also described in the release schedule https://peps.python.org/pep-0596/

Linux is no longer unix. Only exception is slackware. Use slackware.

[dapper musk]

sure there is nothing better than installing dependencies manual...

[barren temple]

Package managers nowdays do database, interwebs, packages, installation.... Soon they will brew coffee. It is so easy to ldd to see what your deps are and just install them. And packages are just tarballs. And init files are good old bsd style init scripts. Who needs more?

It's the ||april trolls|| truth. Do not question it. Linux is just inferior to slackware.

I'm assuming you have installed python3-dev and python3-apt?

[barren saffron]

yes both

[spark mulch]

What's your python/python3? Is it the system-installed Python, and have you messed with it in any way?

[barren saffron]

Is the problem maybe that I installed python 3.11.2 and made it the default version

[spark mulch]

Yes.

[barren saffron]

oof

[spark mulch]

Don't ever change the system python.

[barren saffron]

okay

[spark mulch]

If you want a newer Python to work with, I recommend using pyenv to install it in addition to the system Python

so I have both installed python 3.11.2 and the system one but python 3.11 is set to default

What do you mean by "set to default"? With update-alternatives?

First try to set the previous version as the default again and/or uninstall Python 3.11

[barren saffron]

okay one sec

[barren saffron]

I'm confused how do I do that?

[spark mulch]

Well, you say you set it as the default with update-alternatives, right? Then set it to the previous version. What distro are you on?

Im sorry 😂

I wanted to say: If I uninstall python 3.11, does the system python version automatically set itself as the default again?

[spark mulch]

It should, yes.

[barren saffron]

Kubuntu

[spark mulch]

Which one? 22.04?

[barren saffron]

22.10

[spark mulch]

That seems to have come with 3.10.
If after uninstalling 3.11 it doesn't work yet, reinstall python3

[barren saffron]

Wait I will try this

huh

I can't uninstall this

[spark mulch]

How did you install 3.11? deadsnakes?

[barren saffron]

sudo apt install python3.11

[spark mulch]

Did you first add some PPA, e.g. the deadsnakes one?

[barren saffron]

And then I used update alternatives

[barren saffron]

Umm yes I added some PPA but I don't know if I added deadsnakes

[spark mulch]

Hm.. can you run sudo update-alternatives --config python3 and select 3.10 there?

[barren saffron]

I did that

[spark mulch]

And it let you select 3.10?

[barren saffron]

Wait I will try if it work now

[barren saffron]

yes

side question

How to install graphics driver for nvidia gtx 1050 ti?

[spark mulch]

¯_(ツ)_/¯

[barren saffron]

😂😂😂😂😂😂

I'm sorry

Oh and the python problem is now solved

N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.```

[barren saffron]

Huh

this pops up when I do $ sudo apt update

[spark mulch]

You should be able to remove the deadsnakes ppa now

And as I said, I recommend using pyenv for newer Python versions these days.

(Deleting works with the same add-apt-repository call, but with an added --remove. Or just remove the corresponding .list file from /etc/apt/sources.list.d/)

[barren saffron]

Oh its solved

Thank you so much

[barren saffron]

Uhh

[barren saffron]

I installed a Nvidia graphics drive and now my Linux kubuntu is a console window

Please help what did I do wrong

[fallow tusk]

The driver you should be able to find with something like sudo apt search nvidia

[barren saffron]

Yes but now I just have a black console window

Nothing else

[fallow tusk]

Does startx do anything? (it may not…or it may give you an error)

[barren saffron]

Wait I will try it

When I type startx it says command not found

[fallow tusk]

OK. That's one option I was expecting :)

[barren saffron]

Can I fix my kubuntu?

[fallow tusk]

kubuntu…running SDDM, I'm guessing?

[barren saffron]

Kubuntu dual boot

Help me please

[fallow tusk]

Assuming it's using SDDM (iirc, that's default for Plasma/KDE), have a look - do you have a /etc/sddm.conf?

[barren saffron]

Wait

[shrewd stratus]

apparently startplasma-wayland should work

[barren saffron]

It does not

[fallow tusk]

If it's defaulting to Wayland, that would be why startx isn't present :)

I wonder what DM runs for Kubuntu, then…can't recall how to find out :/

[barren saffron]

I reinstall it

But

What is the right way to install a graphic drive for 1050 ti?

[fallow tusk]

Reinstall what?

[barren saffron]

Kubuntu

[barren saffron]

?

[fallow tusk]

Do you know it's the missing graphics driver that's causing the problem right now? If not, and you had it working previously, don't go adding more complexity in until you've got things back to a working state

[barren saffron]

Idk. I just reinstall kubuntu rn but another question

What is the right way to install a graphic drive for 1050 ti?

In kubuntu

Because I wanna play Minecraft or something

[fallow tusk]

There should be a dkms package, iirc…

I was hoping to see something like nvidia-dkms, but all I see are versioned packages…you probably just want to choose the latest (nvidia-dkms-525, maybe?)

[barren saffron]

I installed this (nvidia-dkms-525) then I rebooted and just got a black console window

[craggy tartan]

how do i add a help for a shell script program

My teacher is asking me to: "Include a usage description (otherwise known as a help message) that describes how to use the script if the user calls the script with a command line argument of -h"

[fickle granite]

write something that looks at the script's arguments, and if it see one of them is -h, it emits the help message

[prime magnet]

https://docs.python.org/3/library/argparse.html

[fickle granite]

that's for python, not shell scripts

[craggy tartan]

that's for python, not shell scripts.

im not learning python, im already over that phase. I am learning unix scripting and i need to do this for bonus marks for an assignment.

[fickle granite]

very simple example (cadged from stackoverflow) ```
#!/bin/sh

OPTIND=1

while getopts "h?:" opt; do
case "$opt" in
h|?)
echo "Usage: $0 [whatever]"
exit 0
;;
esac
done

shift $((OPTIND-1))

[ "${1:-}" = "--" ] && shift

echo "OK, now let's get to work: $*"

there's a million other ways to do it

[craggy tartan]

So would the best way to do it would be a case with h)

[fickle granite]

I don't understand the question

Also there's probably no "best" way; or, rather; the best way is the one that is best for you

'course this is homework, so it's all about making the instructor happy 🙂

[vagrant fern]

if startx is not found then my guess is you dont have x11 installed

[candid dove]

I dont really like that statement. There are certainly best practices. And code only you understand is certainly not good

shellscripts are often especially hard to read so its even more important to use standards

[wise forge]

considering limitations of bash, best practice is not using bash for making CLI programs / long scripts.
Use smth else... python ^_^ library argparse is awesome.

[fallow tusk]

Given the context, it was a decision between selecting to use just h or both h and ?… something that's likely more dependent on the project requirements.

[vagrant fern]

shell script is the best way to script shell commands. if you have a deployment script that copies something from a to b and restarts a service, shell is what most people will understand best

[main olive]

but it's interrupting my build

I can't create build with this warning

what to do?

[fickle granite]

tell your build not to stop when it sees a warning, I guess?

[fallow tusk]

-Wno-macro-redefined (or just remove the existing -W)

[main olive]

how?

[main olive]

what is it?

[fallow tusk]

Or, of course, fix the redefinition.

The compilation is using -Wmacro-redefined (as shown in your output)

[main olive]

ohh

So, how can I remove the -W

[main olive]

.

[fickle granite]

I have no idea what you're doing, so i cannot tell you how to fix it.

[main olive]

I'm converting .py to apk with kivy using buildozer

In Ubuntu

[fickle granite]

never heard of buildozer; sorry

[fallow tusk]

Kivy?

[main olive]

yup

[fallow tusk]

Yep.

No idea why it's doing that…iirc I had to make it rerun at last once to get it building when I played with that

[main olive]

ohh

[urban escarp]

Hey

[west umbra]

Do you know who Richard Stallman is?

[urban escarp]

Ofc!

One of the developer

[west umbra]

How come you not know about Free software of then?

[west umbra]

Of what?

[urban escarp]

Unix

[west umbra]

You are wrong, he started GNU project which is Free(opensource) operating system. And GNU stands for GNU's Not Unix

Its not Unix

Its Unix-like

[urban escarp]

No no no

He is one of the original develop of UNIX! Come on read!

No sorry my mistake!

He did not make unix

Rather GNU which is a copy of UNix

[west umbra]

Its not a copy its inspired

[urban escarp]

Yes and even SCO filed lawsuit!

[west umbra]

Come to the the offtopic channel

[fickle granite]

you know, there's this thing called "Wikipedia" which answers these sorts of questions.

[west umbra]

Lol

[urban escarp]

Dude your knowledge is still lacking, you should read more!

[west umbra]

Already wasted too much time reading FSF.org and stallman.org

[urban escarp]

If software should be free, why also not hardwares!

[quick tapir]

everything should be free!

[misty yew]

its not about the price its about the freedom

i can tell you didn't even bother reading the homepage

[vagrant fern]

I finished setting up my selfhosted email server 🥳

Works and delivers. I have a clean IP from a reputable provider so that probably helps

For anyone wanting to make their own, I used this guide: http://workaround.org I may also publicize my Ansible role to host it sometime.

[fickle granite]

wow, I'm surprised. I assumed that in practice you'd have to pay someone a lot of money to get a "clean" ip address

[vagrant fern]

I thought the same, but figured might try anyhow 🤷‍♂️

I have a friend who selfhosts with mailcow and the only hurdle he had was that one German ISP asks for contact data on your website (for abuse etc. I'm assuming)

[fickle granite]

out of curiosity, why did you do it?

[vagrant fern]

just curiosity and interest in learning about postfix and dovecot, apart from that I'm a big fan of selfhosting

[fickle granite]

curiosity is the best motivator IMO

[vagrant fern]

indeed :D

https://maddy.email also looks like an interesting upcoming project

[fallow tusk]

Cue comments about cats.... }:)

[fickle granite]

wouldn't dream of it

[bitter salmon]

I ended up falling asleep yesterday, are you around now or sometime this week?

[fallow tusk]

I'm here, but not at home.

[bitter salmon]

well. let me boot into manjaro and share some errors with you

[fallow tusk]

Sure.

[bitter salmon]

so you can know about it, and maybe give some feeback

[bitter salmon]

alright, 501 updates later and im here

@fallow tusk how can I share details with whats going on. whenever I activate wayland after install i just fall back to a black TTY (I think at least) and some emacs like shortcut pressing later i am back to the login screen

the hardware relevant but the same errors are there before x11 enters

[fallow tusk]

Can you ctrl-alt-2 to get tty2 up?

Not sure about the errors, tbh…can't tell if they're important or not!

[bitter salmon]

KDE plasma works well with that error at least

you mean ctrl alt 2 while im trying to get into wayland?

[fallow tusk]

Plasma X11, I assume :)

Yeah… should give you a tty you can use to execute commands to see what's going on

[bitter salmon]

yes, Plasma X11

should ctrl-alt-2 work now? because it does not do anything

let me switch and try

[fallow tusk]

Sorry - c-a-F2!

[bitter salmon]

I get to the same TTY screen shown in my screenshot, cant input commands

same when im in X11

[fallow tusk]

Hmm. And the same with C-A-F3 or C-A-F8?

[bitter salmon]

yes, no change when i use one of the other F keys

[fallow tusk]

That's unusual, but I think you can disable that...

Just starting up a VM to check what I'm telling you!

[bitter salmon]

maybe my KDE version is to new?

Operating System: Manjaro Linux 
KDE Plasma Version: 5.27.3
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8
Kernel Version: 6.2.9-1-MANJARO (64-bit)
Graphics Platform: X11
Processors: 24 × AMD Ryzen 9 7900X 12-Core Processor
Memory: 125,0 GiB of RAM
Graphics Processor: NVIDIA GeForce RTX 4090/PCIe/SSE2
Manufacturer: ASUS

[fallow tusk]

This is what I get from C-A-F2

[bitter salmon]

that is what I used to get on my old system

It might be purely driver oriented and i know that nvidia is a pain

might have to wait for plasma 6 to arive

[fallow tusk]

Yeah, but it ought to work. I'm sure I've had a Plasma/Wayland setup running on Arch.

I guess you can view the logs from Plasma X11. I was going to suggest a live USB and digging from there (arch-chroot is a wonderful thing!)

I guess you've seen this: https://forum.manjaro.org/t/howto-use-wayland-with-proprietary-nvidia-drivers/36130

Any instructions that end with the step 7. Profit have to be good, right? :D

[bitter salmon]

it looks promising, but i never installed GNOME as far as im aware

ahh part 4

[fallow tusk]

Yep, ignore the Gnome stuff

[bitter salmon]

well, part4 is very implicit for me, no idea what they want me to do

should i add it to MODULES='' you think?

MODULES="nvidia, nvidia_modeset, nvidia_uvm, nvidia_drm" like so, with commas between?

or without?

[fallow tusk]

Let me have a look at mine - if I recall correctly it is space-separated

[bitter salmon]

space seperated worked

and i already had the second part of part4 done

alright.. rebooting into GNOME Wayland now.. lets see

[fallow tusk]

Gnome?

[bitter salmon]

the link said gnome wayland, but it did not work, same thing

I can try to install another distro though

would booting another distro and formating my SSD with manjaro mess up my boot loader and my option to boot into windows you think?

and do you have any distro recomendations?

[fallow tusk]

It shouldn't. The grub installation will try to detect other OSes, and it's usually good at finding Windows

[bitter salmon]

nice to know

[fallow tusk]

Manjaro's probably a good one, or Ubuntu of whatever flavour you fancy (I like Lubuntu for its size - LXDE, but Kubuntu is the KDE Plasma variant)

[bitter salmon]

so maybe manjaro GNOME could be a good fit to test out?

[fallow tusk]

Maybe, although I tend to stick clear of Gnome - it's always seemed slow and clunky; trying to use everything the machine has just to add a few bells and whistles to the GUI. (But, yes, this is like me preferring petrol manual cars because historically I've found them better, even if the automatic diesels are a heck of a lot better now)

[bitter salmon]

I also have the same general feeling about Gnome

but since Manjaro Plasma is not working as I want it to, I can just try and see

[fallow tusk]

Have you tried a full reinstall of Manjaro Plasma?

[bitter salmon]

yes, this is a clean new install

[fallow tusk]

Weird.

[bitter salmon]

yeah, I cant even get i3 to work, so im opting for a driver issue

[fallow tusk]

Yeah, almost certainly.

[bitter salmon]

I do however have no idea how to debug it. it all worked very well with my RTX 3090

[fallow tusk]

Probably something to do with those errors you're getting at the start ;P

I'm unlikely to be able to replicate if it's an nVidia issue - I have a Radeon card in the laptop. It's the desktop that's got an nVidia.

(but the desktop is out of action atm, anyway)

Of course it just defaulted to X11

[bitter salmon]

yeah, thats the default.. but I might just get a new SSD and test out other distros via that one. I just want to test out new stuff and see if i like it.

[fallow tusk]

I like to play with distros every so often, too. Although I do tend to use VMs to do that.

[bitter salmon]

yeah, but you know, hardware and nvidia

im getting a new SSD tomorrow or order it online and have it ready for the next weekend

[fallow tusk]

Good luck!

[weak otter]

Hi everyone. Having this weird problem with running a large matrix computation using np.memmap. I can't tell if it's an issue with python or something about the hard disk. I had the disk wiped clean, checked for errors, formatted in ext4. The disk space is 2 TB, and I make 11 large matrices of size 90 GB. That's just 990 GB, but then suddenly, the computation stops and the terminal disappears. The memory consumed also just shows 500 GB, when there are 7 large arrays. Is there a way to track exactly where this issue is originating from? I just know that it stops while making a specific array, and that's it. From what I know so far, disk looks clean and no issues with reading/writing. But I don't know, maybe there is some sector that is bad?

[fickle granite]

if this is Linux, you can tell if it's an out-of-memory error by looking in /var/log/syslog for hints that the "OOM killer" ran

[urban drift]

+1 to this being an OOM issue, also check your ulimits with ulimit -a

Bad sector would hang or silently rearrange, especially if you're only writing out half the available disk space

Check your SMART bits if you're on spinning metal & worried about disk failure https://manpages.ubuntu.com/manpages/jammy/man8/smartctl.8.html

[fast barn]

I try to use this command
ls files_{7..10}
However since the default shell in my terminal is csh, this didnt work.
I find a solution to use

foreach i ( 7 8 9 10 )
ls files_i{$i}
end

But how i can apply this on the terminal since it takes just one line?

[fickle granite]

another solution is to use a different shell

❯ bash -c 'echo ls files_{7..10}'
ls files_7 files_8 files_9 files_10

[fast barn]

Nice
So this will run the command in a bash, regardless of your default shell right?
Because my default shell is csh

[shrewd stratus]

you can also replace csh with bash by putting exec bash as the only line in your cshrc, if you don't have the access to change your default shell

[fast barn]

I will try this out, as you say i have limited access to lot of things

another question
When i check the machine i work on using lscpu command
I found that i have total 4 threads.
so if i need to make parallel execution it can’t be more than 4 at once.
ls directories |xargs -n 1 -P 15 du -sh

And then check cpu using top command i found that its list the 15 job, is that possible to work on all of them in parallel with the 4 thread system

[shrewd stratus]

one CPU core can make work on multiple threads concurrently (by switching between them periodically)

specifying the process count equal to the number of available cores minimizes the number of such context switches

you can do that like xargs -P $(nproc)

[craggy kite]

I made a thing. It makes Python CLI tools start much faster.

I now use it to make my pre-commit hooks blazing fast. It's nice for git commit to be near-instant again, even with pre-commit checks!

It's called JumpTheGun, because it makes Python tools win the race by cheating 😉
https://github.com/taleinat/jumpthegun/

So I'm looking for early adopters. If you like, give it a whirl and let me know how it goes.

[spark mulch]

Clever idea. I'm gonna try it out when I get back from vacation.

[runic goblet]

neat! had a quick look at the repo, doesn't seem to be malicious (can't be too careful with the recent wave of malicious packages found in the wild)

i am not sure what is the cause, but some entrypoint scripts seem to be written with " as opposed to ' (maybe it was generated by a different template or something), as such the find_entrypoint_func_in_entrypoint_script in your lib fails to detect the entrypoint func

fwiw, i was testing using sqlfluff

[craggy kite]

Good catch, thanks!

[main olive]

what is the lightest possible linux? my laptop is a potatato so i need sped

[wise forge]

you need light in GUI then Linux. try going Lubuntu then https://lubuntu.me/ 22.04 LTS can be an interesting choice

[fallow tusk]

If you don't need a gui, there are much smaller footprint linuxen

Alpine, for example…but it's light for a reason - it doesn't have much more than the minimum necessary to get an OS up and running

[wise forge]

as far as i understand goal is not small in size, but being lightweight in performance ^_^
so there should not be point to choose stuff like alpine, but better choosing stable in working ubuntu/debian based smth, just with lesser performance requirements

small footprint OSes aren't good for desktop, hardly anything can be booted on them easily

laptop mentioned hints, he needs desktop stuff probably

[fallow tusk]

I agree, but with just "lightest possible linux" to go on, the rest is just assumption (and I specified my assumptions so they could choose based on what they actually need, or come back stating their assumptions)

[main olive]

yes, I did mean "fast in performance", but I might still check out the one you sent me

[fallow tusk]

A gui is always going to be slower than a command-line only interface :D

[craggy kite]

Fixed in the latest release.

[runic goblet]

lovely, i actually submitted a PR but i didn't add a test ha
thanks!

[lethal trail]

How to bypass grub rescue mode?

[fallow tusk]

That usually indicates that a valid boot config can't be found. iirc the way I've got around that previously is to use a live environment, chroot into my system, and fix the boot - which has usually been caused by an update that got interrupted.

I've sometimes managed to use rescue mode to boot into an existing system, but that tends to involve reading howto instructions on the web :D

[vagrant fern]

This looks super cool. How does it work? My understanding is you start the service in the background and then simply cat stdin and stdout to the sockets of the service

[main olive]

irrelevant right now but, to my knowledge, tiny core is around 16mb. has a gui and has the linux kernel. if you want a os you can actually use though, i would recommend maybe peppermint or some light diy distro. both i've used are pretty good.

[craggy kite]

That's sort of the gist of it, but the devil is in the details, and there is definitely more going on than what you wrote. I hope to write about that soon.

[vagrant fern]

debian with icewm

not the „lightest possible“, if you want the lightest possible probably slackware in text mode or something

[main olive]

thx

[vagrant fern]

if you want something lightweight to manage files on your desktop, install pcmanfm and run it with the desktop flag

runs nicely on an ancient laptop with 2gb of ram

[main olive]

ight

[fast barn]

Thank you 🙏
When i check this variable i got the number 2 so the optimal valur for the parallel running must not exceed it right?

[safe stirrup]

Do interpreters running inside cygwin still provide access to the win32 API via ctypes?

[safe stirrup]

lightest possible
Bunsen Labs is a bit off the beaten path, but it's as light as recognizable DE setups go without becoming really weird

there's no start menu in it, you right click on the desktop to bring up the menu

otherwise the default UI will probably be somewhat familiar

The latest release is based on Debian stable (11) so it might be a little less current than other distros, but it should still get the job done

[fading thorn]

Hello everyone, i would i like to build my python app for MacOS and Linux, but i don't know how to do this. How exactly should i do this?

[My machine is a windows 10 computer and i dont have any ways of running macos or linux]

[spark mulch]

What do you mean by "building"? Normally you can just execute the Python files on any OS.

[fading thorn]

I mean using PyInstaller or similar to make an executable file

[fading thorn]

like py -m PyInstaller --icon=icon --noconsole script.py makes an exe

[main olive]

I don't think people generate executables for python

specially on linux and mac, you just run it

[fading thorn]

The entire BEE2 application is a python script turned into an exe

(the Portal 2 editor addon)

[fading thorn]

really

[main olive]

I don't know any way to turn python code into unix executables so

[fading thorn]

Alright then

Thanks anyway

[main olive]

your welcome

actually

I think pyinstaller can turn python code into executables for unix

let me see wait

https://pyinstaller.org/en/stable/requirements.html#gnu-linux

see this

[ember quiver]

You don't necessarily need to compile a special file or anything like that for Linux: https://stackoverflow.com/a/304896

[main olive]

I saw that sof post, I think they want to build a executable they can share or something

[fickle granite]

fwiw: I've never gotten pyinstaller to work on any platform.
I am more optimistic about https://github.com/indygreg/PyOxidizer although I've not dug into it

[ember quiver]

@fading thorn If this is the case, building a pip package is probably what you want https://packaging.python.org/en/latest/tutorials/packaging-projects/

[hallow herald]

do i need adwaita for dark mode in gtk?

can i theme a gtk application window without adwaita?

[urban drift]

adwaita is the theme itself, you can choose to use any number of themes that aren't adwaita

that's just the default in gnome 3 (citation needed)

[hallow herald]

so what is the theme getting used by gtk without libadwaita?

[urban drift]

ohh libadwaita is something different

isn't that the one that adds CSS support to GTK

[hallow herald]

idk i am just trying out gtk on windows

built it some time ago with gvsbuild

[urban drift]

ah
yes you can apply themes without putzing with libadwaita
afaik libadwaita gives you the ability to customize themeing on a per-application basis

global themes can be applied like normal

https://www.gnome-look.org/browse?cat=135

[hallow herald]

that shouldn't matter on windows right tho?

since gnome is separated from windows anywyas

[urban drift]

my educated guess says the only thing that gtk on windows changes is the path location for the themes

it'll be somewhere in %APPDATA%

but I'm not certain it'll all work the same

[hallow herald]

gtk on windows is surely a mess

[urban drift]

i wouldn't know, my windows install is strictly for league of legends

[hallow herald]

although, all that gnome jank and all the dlls are still somehow half the distribution size of pyqt's wheels

[urban drift]

lol pyqt

[hallow herald]

what an overbloated lib

[urban drift]

QT is a dead technology since 6 went proprietary anyway, we just gotta wait the couple years for qt5 to go EOL

[hallow herald]

what will happen to kde then?

[urban drift]

last I checked they had plans to continue security patches on qt5

[hallow herald]

And isn't wayland qt also?

[urban drift]

naw, not strictly

[hallow herald]

i mean qt was a sizeable part of linux gui

[urban drift]

qt6 is like a full rebuild of the thing that the Qt foundation is trying to push

nobody's going to be on a qt5 -> qt6 upgrade path

5 will probably just get forked, idk, I haven't looked at the licensing

[hallow herald]

forks that try to make Qt stick more with std C++ exist

like copper spice

[urban drift]

cool stuff. then maybe qt5 simply won't die

laughing at how GTK opted to implement its entire own object system instead of trying to interface with C++

[hallow herald]

qt did the same thing

but it has no c interface

[urban drift]

that is powerful a power move

[hallow herald]

i wonder if i can go ahead and publish gtk wheels for windows

[hallow herald]

vendor lock down tactics

Since those exist at all

[urban drift]

your problem will lie in compiling the wheel, not with packaging GTK

don't native wheels on windows need specific versions of visual studio installed

[hallow herald]

for the compilation, yes

[urban drift]

iirc it was a pain in the ass

[hallow herald]

but gvsbuild automates the entire build process, even creates the pygobject wheels

and i ran a quick pyinstaller test of my hello world gtk example so I know what dlls and dirs are needed for the whole gnome-gtk thing

[urban drift]

The script requires a working installation of Visual Studio for Windows Desktop, Python 3 and msys2.
ahhh, so it is still a pain in the ass lol

gvsbuild looks handy though

Imagine requiring vs and msys2 both

some unix libs haven't yet shifted to cmake land

[urban drift]

mixed feelings on cmake. whenever im on windows and a tool uses cmake I'm relieved. when a linux tool uses cmake I prepare for the worst

[hallow herald]

btw i am allowed to distribute wheels for gtk right?

from a legal pov?

since that might be a reason nobody has done it before

[urban drift]

uhh, I think that falls pretty squarely under "you have to relicense your code under the GPL as well" but as long as you do that I think you're fine

[hallow herald]

i mean it will be all on github anyways

[urban drift]

yeah afaict distributing wheels constitutes "conveyance" under the GPL so your code also must be GPL

/shrug if it's all open source on github you're fine

[hallow herald]

@urban drift u got any gtk experience?

[urban drift]

naw sorry, I have used it for toy projects but nothing more

[hallow herald]

have u used a listview?

[urban drift]

ostensibly yes but any help I give would be out of the docs lol

[hallow herald]

ok but anyways i am trying to add a listview to a window

and the rows appear very thin and have no text in them

def on_activate(app: Gtk.Application, file: pathlib.Path | None) -> None:
    lv = Gtk.ListView(
        model=Gtk.NoSelection.new(Gtk.StringList.new(["A", "B", "C"])),
        factory=Gtk.ListItemFactory(),
        show_separators=True,
    )
    Gtk.ApplicationWindow(
        application=app, default_height=600, default_width=800, title="", child=lv
    ).present()

This is what I am trying

@urban drift by any chance could u help with this?

[urban drift]

I don't know enough GTK off the top of my head to help, I'm sorry. I might search github for some other code that uses a ListView and copy some example code

Which is the best Linux dusto which i can run in my old low end laptop,
I am shifting from windows so i want a windows like desktop

Is there any Destro which fills my recruitment best

I am so confused there are maaaaaannnnnyyy destro and everyone have there specific advantages

😱

[main olive]

linux mint xfce is light and a windows like operating system

[lethal trail]

wow its cool, can i install linux on my portable SSD

linux come with a grub boot loader do it stuck to grub rescue mod if i plug ssd out?

i have win8.1 in internal hdd

and i want to learn some basic of linux before jumping completly to it

[fallow tusk]

If you just want to play with Linux first, I recommend putting it on a VM. That way you can try out different distros and different setup quite easily

[main olive]

i dont think low end laptop can run VM easily

[fallow tusk]

You could set up a VM that mimics your internal and external drives and investigate what happens, and how to set them up

[wise forge]

zorin os lite system requirements are even less. A bit sus it is paid version having though. (has free version though)
Minimal system requirements are 1 GB. can be fitting super old PC.
Looks like windows looking too.

[fallow tusk]

True, although if it's the only thing running…

[wise forge]

indeed. definitely not for the case when it is super old and not powerful

VMs are hungry

[craggy kite]

I'm writing a shell script that will run my Python code via exec, but first I need it to run a background process. Considering that this going to be run in a container as the main process, would it enough to run my background process as python my_background_task.py </dev/null >/dev/null 2>&1 &? Should I be using something like nohup, or something else?

[wise forge]

1. make rethink, maybe your background process should not be background, launch it as side car additional container. Try to keep one container per process

2. if choice one is not available and you still want background process... check, if your logic allows launching it with your programming language mulththreading (or multiprocessing) in background, along side with main process. That is very optimal good choice as well. (especially if using multithreading, because threads used right in a use way, make sure to crash parent as well if problem happened, which makes properly restarted your container. At least this is how it is handled in golang. Not checked in python)

3. ... mm other options are way less prefered at this point, but next prefered choice having parallel process launched in parallel with main one (in same ENTRYPOINT/CMD command!) through & linux shell syntax
   https://www.cyberciti.biz/faq/how-to-run-command-or-code-in-parallel-in-bash-shell-under-linux-or-unix/

4. other options should be not even mentioned at this point

[craggy kite]

Thanks for the detailed response and multiple options!!

Option 1 isn't relevant in my specific case, unfortunately, though "one process per container" is indeed a good guideline to follow.

Option 2 seems basically like 3, where 3 does it using the shell language's API.

I think 3 should be fine, since with exec the current process is replaced, so the background sub-process should be fine until the main process ends, after which it is no longer needed.

[ember quiver]

I always say that if you have to ask, you want some flavor of Ubuntu, because there is a lot of support for beginners like askunubu.stackexchange. You may need to look at a lighter version of it like xubuntu or Lubuntu

[lethal trail]

ok

[river raptor]

i can try

helping you

[fallow tusk]

@lavish adder Do not spam across channels. My suggestion was to narrow your focus to the part that is relevant to this channel.

[lament tide]

If you are new, just use Linux Mint and be done with. It is based on ubuntu and is better than ubuntu in all sense.

Ubuntu creates problem as time goes on. It is not a beginner friendly distro. I always get surprised when Ubuntu is recommend to new Linux folks. Especially if u have time constraints. If u want ubuntu spwcifically, I recommend Xubuntu for a good experience.

If you aren't tied to ubuntu related stuff, I recommend Arch but it is for advanced users. A lot of reading and tinkering stuff needed initially. But extremwly rewarding for long term use. My installation is 5+ years old with zero hiccups.

Pop!OS is somewhere in the middle. A better Ubuntu I have heard. But I haven't used it. But have heard praises from my dev friends.

[lethal trail]

I am choose linux mint

its similar to windows desktop

[lament tide]

Good choice. Its community based distro. It provides full out of the box experience which is expected by a windows user. And works with all the things needed for a dev or a normal user. Like GPU drivers etc. 🙂

Hangout in their forums. They have a wonderful community. 🙂

[lethal trail]

thanks

[hard pilot]

I also am using Linux Mint 🙂

[trail crater]

this... linux mint is the best

user friendly

similar to windows

easy to use

ubuntu has a bunch of issues with snap, performance errors and so forth

mint doesn't have those

and i dont recommend pop os

tried installing it for a friend and the ui was confusing asf

like, why tf do i have to use command line to install a friggin taskbar?

[urban drift]

idk what's with all the ubuntu hate, GNOME 4 has had some serious performance improvements + canonical is still the most reliable when it comes to rolling out security patches

u can simply not use snapd if you don't want it, but most packages that "require" it... don't. It gives you a choice whether you want to download a version from apt or from snapd, it's just that the apt versions are tied to ubuntu releases and the snapd versions are rolling

perks of having an ISP that mirrors the arch repos

init7.net

[river raptor]

they have two plans, was it the private one?

also, is it fasterb ecause you are connected to it?

[real vapor]

private, I have no clue what their business plans are like

considering in the private one you can get up to 25Gbit/s

but you need pretty serious hardware for that

yes

but it happens after I switched to Ubuntu.

I don't use Pycharm, so can't say whether that's a known issue with running it on Linux or not.

it never happened before tho.

what are you using then if you do not mind?

VSCode mostly.

vs code?

[normal dagger]

does it have good GitHub handling?

Yes

Well, I don't know about "good". I've used it to work with some github repositories

[normal dagger]

gonna try that, I don't want to struggle with this issue for years.

[wise forge]

good enough to me, especially if having installed plugin Git Lens

pure inbuilt functionality is kind of enough for 98%+ cases though

since it can already make code reviews and solving merging conflicts

Git Lens just extends functionality and has inbuilt git blame running, and allowing to see Git diff between any chosen brances, and other stuff doing

Hi everyone, I am having issues installing Python3.10 on Raspbian 11.
Here's my approach to installation:
wget https://www.python.org/ftp/python/3.10.11/Python-3.10.11.tgz
tar -zxvf Python-3.10.11.tgz
cd Python-3.10.11
./configure --enable-optimizations
make altinstall

The error I get is the following (excerpt):
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Python path configuration:
PYTHONHOME = (not set)
PYTHONPATH = (not set)

As I understood, I need to set the two variables $PYTHONHOME and $PYTHONPATH, but I have no idea how to do so.

[ember quiver]

Are you asking how to set them (https://pimylifeup.com/environment-variables-linux/) or what exactly to set them to?

[deep rivet]

Both 🙂

I actually managed to install python3.10.11, but I still get this error when I try to run it

I mean, I am able to set a variable on linux but I don't know what to set it to

[fallow tusk]

prefix and exec_prefix will be defined by the configure script

Iirc, exec_prefix is usually /usr/bin

[deep rivet]

Sorry I don't get it

[fallow tusk]

It tells you to bash Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>], yes? You can find those in one of the output files that was generated when you ran bash ./configure --enable-optimizations (they'll be one of the newer files in the Python-3.10.11 directory; I can't recall the name - something like configure.conf, perhaps)

[deep rivet]

aaaaah ok I'll have a look!

I got the following:
prefix='/usr/local'
exec_prefix='${prefix}'
What do I do with it now?

[fallow tusk]

Do prefix and exec_prefix are both /usr/local, so the suggestion is to set PYTHONHOME=/usr/local (although that doesn't feel quite right to me. Perhaps it is...)

[deep rivet]

I tried "export PYTHONHOME=/usr/local" but when I try to start a service (home-assistant) based on python 3.10, I receive the very same error

[fallow tusk]

I assume that make altinstall completed successfully

[deep rivet]

https://pastes.io/7swtoth5qx

I actually used "apt install python3.10"

root@GC01hass:~# python3 -V
Python 3.10.11

[fallow tusk]

I'm unsure. It's claiming it can't find encodings, which is part of the standard library. That suggests that something didn't go well with the installation. I'm a bit worried that you've tried to install by both a manual compile and using apt; I wonder if they are interfering. I would go through and uninstall the versions you have installed, and clean up from the manual install steps, then just do the apt install from clean.

[deep rivet]

ok! I'll give it a try 🙂

thank you so much in the meantime

[fallow tusk]

(tbf, this is almost the "turn it off and back on again" approach to problem solving!)

[deep rivet]

LOL, I can't even apt purge because I get the same error!

[fallow tusk]

That sounds like it's trying to use the installed version for the system python. Try unsetting PYTHONHOME

export PYTHONHOME=```

[deep rivet]

but it says
Python path configuration:
PYTHONHOME = (not set)
PYTHONPATH = (not set)

[fallow tusk]

which python
which python3``` ?

[deep rivet]

(how did you write formatted as code?)

Here's how to format Python code on Discord:

For long code samples, you can use our pastebin.

[fallow tusk]

OK…so no python; I am going to hazard a guess that you also have a python3 in /usr/bin…

[deep rivet]

root@GC01hass:~# whereis python3
python3: /usr/bin/python3.9 /usr/bin/python3 /usr/lib/python3.9 /usr/lib/python3 /etc/python3.9 /etc/python3 /etc/python3.7 /usr/local/bin/python3.10 /usr/local/bin/python3.9 /usr/local/bin/python3.9-config /usr/local/bin/python3 /usr/local/bin/python3.8-config /usr/local/bin/python3.8 /usr/local/lib/python3.9 /usr/local/lib/python3.7 /usr/local/lib/python3.8 /usr/share/python3 /usr/share/man/man1/python3.1.gz

[fallow tusk]

Yep, so what is your PATH?

[deep rivet]

python3 = /usr/local/bin/python3.10

I think...

[fallow tusk]

Yep, that's what this is saying

I'm a bit unsure, but either /usr/bin/python3 has been linked to the wrong version or it's not being found (due to PATH??)

[deep rivet]

aaaaah yes I think it's my fault

root@GC01hass:~# ls -l /usr/bin | grep python
lrwxrwxrwx  1 root root       23 12 mar  2021 pdb3.9 -> ../lib/python3.9/pdb.py

-rwxr-xr-x  1 root root  4703672 12 mar  2021 python3.9

should I remove the softlink?

[fallow tusk]

It probably needs to be linked to /usr/bin/python3.9

[deep rivet]

still doesn't purge :;(

[fallow tusk]

I'm a bit stumped, now :(

[deep rivet]

Yeah

I think I might reinstall the whole OS...

[fallow tusk]

Probably easiest at this point

[deep rivet]

Thank you so much for trying to help 🙂

really appreciated!

[fallow tusk]

Hey guys I followed instructions from a book (copied and pasted): $ pip3 install jupyter; sudo pip3 install virtualenv

Can someone help fix my python3/pip3?

[wise forge]

Now every time I do anything I get errors:
this is not very precise what you are doing

also this does not specifies which Linux distribution you have

[wanton star]

Just running pip3 on its own produces the above errors

Ubuntu 20.04 LTS Desktop x64

[wise forge]

oh, i am user of similar distro ^_^ used Kubuntu 20.04 LTS for the last 2-3 years

[wise forge]

hmm, i am 100% sure in my diagnosis, but i believe you screwed up System Python of a distro, through running it with sudo

which installed some new files with permissions of a root user

and since you work from a regular user -> you are no longe rhaving right permissions to acces it

[wanton star]

Great! Thats what I get for following instructions from a book

[wise forge]

ergh, this situation is easiest to fix by reinstalling OS i believe.
if you have nothing important on it, it is the easiest way, unless u wish to find some obscure instructions to repair it regardless

screwing up System Python is one of those reasons where reinstallation is easiest to fix ^_^

[wanton star]

Honestly, do python authors ever check their articles?

For the last 10 years (I kid you not) everytime I follow an article about Python it always ends up in disaster

Every. Single. Time

[wise forge]

xD try stuff in docker containers first. or in virtual machines

for any dubious risky stuff i run docker run -it ubuntu:20.04 bash first

it creates me temporal container isolated from main system and connects me to its bash console

that is very lightweight and has its own... simulated system inside

from there i can do more risky stuff (including safely running deleting everything)

[wanton star]

I could literally follow instructions on a Python 'Hello World' script and it would break my system

because the idiot author would fail to mention things like: oh, this code is for Python2. Like, seriously

This is why I will never buy handover money for a Book or Subscription. Its all utter garbage. All of it

[wise forge]

https://brain2life.hashnode.dev/how-to-install-pyenv-python-version-manager-on-ubuntu-2004
as alternative, you can install pyenv if u want. it creates global other python versions running on OS, that are different from System Python
if u screw them up, that will be not a harm in comparison to System Python

technically

technically

[wise forge]

u just need to survive to the moment of venv creation ^_^

and its activation

after that you are able to screw up stuff too, it will mess up only local created venv copy

it is easy to do at ubuntu

venv is already usually installed

[wise forge]

python3 -m venv venv in desired folder, source venv/bin/activate (to activate and get inside of it)
if it is not installed, then run sudo apt update and sudo apt install python3-venv

once venv is activated, you are safe in isolated venv environment

where you can break stuff if u wish ^_^

[wise forge]

for this reason of posibility to break System python, i did not even install pip3 on my system python btw (by default it is not installed)

i just created venv in my user folder (~/venv), that i connect in parts for globally installed stuff

alias jypiter="~/venv/bin/jypiter" in my ~/.bash_aliases file create me global access easily to venv installed stuff for global specific stuff

[candid dove]

What is Jypiter? Something different from jupyter?

[fickle granite]

typo probably

[candid dove]

probably. Just wanted to make that sure

Anyway, so you got a global jupyter installation and just install ipython in other environments if you want to use the kernel in a notebook, right?

[wanton star]

Nah I've since uninstalled that piece of $shit. The author can't explain why jupyter is installed without sudo but the 2nd command has sudo, jupyter installed with a bunch of errors and warnings in red and orange respectively. Seriously the world of python is garbage

I remember last year in a different distro (EndeavourOS), python venv f'ed the package manager. Somehow it decided it was the default python. All from following a hello world tutorial

10 bloody years and I still havent been able to follow a Hello World tutorial without something breaking across 100 Linux installations in 10 years

Forget about something more complicated like web scraping a page, these idiots don't even fact check their articles

or their books.

My tip: Don't ever pay $$$ for a python book. Pirate it. The author aint worth a single cent

[wanton star]

Well I thought I uninstalled jupyter but the binaries are still in ~/.local/bin
So I had to install the garbage pip3 again, add myself to the 'staff' group so pip3 doesn't shit itself with PERMISSIONS errors (genius development there folks)
Attempted to uninstall jupyter, it tells me jupyter is not installed - WTF
So I pip3 install jupyter - that "works", there is a red error, nice one guys, my Ubuntu install isn't tainted with 3rd party repos whatsoever, never has been
So now I can finally run pip3 uninstall jupyter, that "works" but the binary files are still in ~/.local/bin
I uninstall python3-pip package. F this python platform

Removed myself from staff group too to unf*ck the mess

[fallow tusk]

I don't think you can put the blame on Python for issues you had installing Jupyter - especially if you were following something other than the official docs.
I've definitely had issues when I've made a mistake in an install - especially when I mis-linked the system python to a user-installed Python. But that was definitely an error on my part.
You certainly can't put blame on Python for something some third party writes. Stuff on the web is often wrong, or even if wasn't wroog when written, it may now be out of date. This is the case for any evolving system

And, in the end, there's nothing we on the server can do for you. If you want help or advice, ranting about how terrible Python is is likely to get you ignored rather than helped.

[wanton star]

https://wiki.python.org/moin/BeginnersGuide/Download
Nothing special.

Is pip3 part of the vanilla Python distribution?

Its easy enough to do a 'sudo apt install python3-pip', but then pip3 shits itself with PERMISSIONS errors just running it without any parameters

[opaque ginkgo]

what error

If the answer to the above is YES, I would say Python3 really is a pile of poo

[opaque ginkgo]

and that's from running pip3 install jupyter?

[wanton star]

yes, or just running 'pip3' on its own

[opaque ginkgo]

oh I see

the sudo fucked up everything

[fallow tusk]

pip is part of the standard install nowadays, although it was a separate piece previously (but I believe that was pre 3.8). You do still seem to have to apt install it separately, though. It should default to installing packages to a user-accessible location (there used to be a --user option that would enable that, but it should now happen by default)

I don't have access to a Ubuntu install right now, so I can't try to recreate what's happening.

Looks like Ubuntu has 3.10 in the repos from 22.04…are you on an older Ubuntu?

[opaque ginkgo]

.

[fallow tusk]

23.04 has Py3.11…

20.04 has 3.8.2; that should still be pretty standard. I'm reasonably certain that even by then --user was unnecessary

[runic goblet]

if i remember correctly, using the system's installation of python's pip will usually print out a warning saying you shouldn't be doing that. this is maybe a new thing from the past year or two, i don't really remember.

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead
from a quick google search.

imo the most correct thing to do is just use pyenv to install your desired python version, make a venv out of that, then install jupyterlab in said venv. (venv is virtual environment in case you aren't already aware.)

re. your point to book author not fact checking their content, the python packaging system is a quickly evolving system, the author might have the correct ideas at the time of writing it, but it might have been outdated now. and in any case, ditto on Hsitirb's point, ranting will unlikely get you the help you require

[wise forge]

pip by default is not installed in 20.04 and in 22.04, requires python3-pip installed.
and it should not be installed
because messing with system python is bad. venv is available by default and already installed

if u need global python packages installed, better creating user specific venv and aliasing stuff from it ^_^

[fallow tusk]

I think I've probably needed system pip installed for things like pipenv - basically anything that's needed to bootstrap a venv, but nothing more

[runic goblet]

i take a more paranoid approach of installing a completely separate installation of python with pyenv, but the principle of "don't touch system installation of python if possible" is still the same

[wise forge]

i don't like pyenv for how it messes with my shell. a bit fragile in its working

not installed pip, and using alias flake8="~/venv/bin/flake8" in my ~/.bash_aliases i think is more reliable and less messing around

[runic goblet]

to each their own 😉

[wise forge]

going probably to install anyway may be, when default 3.10 python will become too old to use ^_^

[steep sequoia]

good principle- i once replaced /usr/bin/python3 to be the newest version of python and a lot of stuff broke. i still had the other version of python installed, it was just that python3 pointed to a different version (3.11 instead of 3.10). i would think that if they've got something version specific they would use that specific version (e.g. /usr/bin/python3.10 if they have something specific to python 3.10) but no, apparently not

¯_(ツ)_/¯

[fallow tusk]

It's not version-specific, though…it's release-specific (they may need to update a script or two when the version of Python is updated for a new release, but they don't have to change every single Python script)

[hexed cave]

Annoyingly due to a mistake virtualenv depends on python3-pip in Ubuntu 22.04

[wise forge]

checked out of fun in Kubuntu 22.04
python3 -m venv venv is available with installed python3.10-venv/jammy-updates,jammy-security,now 3.10.6-1~22.04.2ubuntu1 amd64 [installed] but without python3-pip

i have it as main running OS anyway ^_^

$ sudo apt list --installed | grep "python"
python3.10-venv/jammy-updates,jammy-security,now 3.10.6-1~22.04.2ubuntu1 amd64 [installed]
python3-pip-whl/jammy-updates,jammy-updates,jammy-security,jammy-security,now 22.0.2+dfsg-1ubuntu0.2 all [installed,automatic]

[hexed cave]

yeah venv works but I'm using virtualenv via virtualenvwrapper

I did pip config set global.require-virtualenv True instead

[steep sequoia]

which is why it confuses me that stuff breaks

there shouldn't be any version specific stuff

[river raptor]

Kubuntu was my First distribution

I still use KDE Plasma But i might Switch to another DE or a WM, im Not sure yet

[fallow tusk]

It breaks if you install a different version than the released version because it's not the released version. When that version becomes part of the release, all the scripts that need to be updated will be.

I am trying to manipulate Windows filepath in an application running on ubuntu and centOS. What is the best way to do this?

[fallow tusk]

You can probably use pathlib with the windows-specific class.

!e py from pathlib import PureWindowsPath p = PureWindowsPath("C:\\") print(p) print(p / "User")

Does anyone know a command similar to more where I can look at a .py file with syntax highlighting? (Please do not tell me how to make more relay colors that are already encoded in the file--that is not my question.)

[fallow pumice]

bat, either find it in a Linux distro or then compile it in via Rust.

https://github.com/sharkdp/bat

[granite aspen]

thank you, you are better than google.

[ember quiver]

Vim?

[granite aspen]

vim sometimes plays poorly with tmux, which is annoying when I'm not trying to edit the file anyway

[shrewd stratus]

you can open the file in vim as readonly as well

[granite aspen]

that doesn't fix the problem

[shrewd stratus]

which is?

bat is definitely the best solution, ngl

[granite aspen]

if I'm using tmux (which I often am), opening something with vim sometimes makes the terminal all fucky. whether I plan to edit the file or not.

[shrewd stratus]

hmm, that's strange
I (and many others) use the tmux + vim combination daily

it could be a tmux and/or vim configuration issue

[granite aspen]

I've never configured either

[shrewd stratus]

or the terminal as well

[granite aspen]

I use cmder

[shrewd stratus]

I've never used that, so can't tell ¯_(ツ)_/¯

[granite aspen]

it's the best bash console for windows that I've used so far (my host machine is a windows laptop, but I do everything on linux VMs)

[shrewd stratus]

not a Windows user, but I've heard good things about Windows Terminal

[granite aspen]

isn't that win11?

[shrewd stratus]

it's also available on Win 10

Win 11 is when it became the default

[granite aspen]

hmm

did they finally get rid of cmd

[shrewd stratus]

in true Windows fashion, no

[granite aspen]

[ember quiver]

No, even on Win 11 both are there

Terminal can use CMD or PowerShell or WSL at the same time

[steep sequoia]

nano has fairly good syntax highlighting by default

nano -v for readonly mode

[steep sequoia]

nano is installed by default on most distributions, and also on windows via things like Git Bash (and iirc Win Bash)

if worst comes to worst, you could always write a syntax highlighting script and pipe into it with cat <file> [file...] | highlight.py

or something similar

if you do that, then you could probably cheat by using things like tokenise and ast

but that still sounds like a lot of work

im fairly late to the conversation but hopefully my confused ramblings were a bit helpful

[narrow fern]

time.process_time() calculates its value from /proc/[pid]/stat, right?

is it (utime + stime) / sysconf(_SC_CLK_TCK)?

(https://docs.python.org/3/library/time.html#time.process_time and https://man7.org/linux/man-pages/man5/proc.5.html for reference)

[summer trail]

no - https://github.com/python/cpython/blob/2cd1c87d2a23ffd00730b5d1648304593530326c/Modules/timemodule.c#L1288

looks like it uses clock_gettime if CLOCK_PROF or CLOCK_PROCESS_CPUTIME_ID is available, or getrusage if RUSAGE_SELF is available, or times if times is available (in that order), finally falling back onto clock() / CLOCKS_PER_SEC

[narrow fern]

Well, that makes it complicated
