unix

[uneven arrow]

I thought that was what you meant

[glacial quest]

big move = more speed

yeah i hate it

[uneven arrow]

Ah

[glacial quest]

i prefer a fixed speed

[uneven arrow]

I thought it was usually tunable

[glacial quest]

especially since i play osu with my mouse, sensitivity is paramount

[glacial quest]

it is

easiest to tune on windows (personal choice, not factual)

[uneven arrow]

I'm a long time unix nerd. Windows drives me insane.

[glacial quest]

if you tinker around with it, you'll find that it's pretty interesting

gives you a whole new look into OSes

my first laptop had Ubuntu, I was 5 too

[uneven arrow]

started young I see

[glacial quest]

of course

but i was a kid

i wanted games

[uneven arrow]

yeah, windows have long had the main share there

[glacial quest]

so when i grew a noggin i moved to windows, then im back on linux

[glacial quest]

before i grew a noggin inside my head, i used to play those Flash games

[uneven arrow]

kind of glad flash is long gone

[glacial quest]

it was a security hazard

[subtle quail]

I'm a UNIX person, but the Windows kernel is interesting. The "Inside Windows" book covers it extensively. If you're old enough to be a VMS user, you'll find some... familiar things in the book.

[fickle granite]

I worked in the NT group when they were developing it; I occasionally saw Dave Cutler in the halls. Scary guy.

[rotund girder]

I'm sad. The nostalgia of old style internet. Browsing somewhere playing a game. But it's not really dependent on the technology. Just those kind of sites don't exist any longer

[nimble notch]

How do I stick myself to unix for longer duration...I find windows better when it comes to build circuits and PCBs...any tips? I want to totally shift myself to unix

[uneven arrow]

Hard to say. Maybe if you find a good circuit design thing for linux or MacOS you can shift.

A friend used to work in a windows shop and liked linux. They installed cygwin and ran its X11 server full screen, so they coul forget there was a windows box underneath.

You can probably do the same with WSL on Windows these days also: run a linux desktop in a full screen window.

That (a) lets you sit full time in linux if you'd like and (b) keep windows around for the tools you still use on windows.

[fickle granite]

If you don't like unix, why force yourself to use it?

Also: cameron's advice about WSL sounds right. I've never used it myself, but I hear it works well.

[uneven arrow]

If you want a new skill, it can be hard if the old and competing skill keep getting in the way.

I once forced myslf to move on from the stock CLI mail command to mush (initially, now an avid mutt used) by refiling my entire email into an MH folder which mail wouldn't handle (it's mbox only) and, initially, wrote myself a small script to make an index file and a set of vi macros to browse it and pick emails.

Just to force myself away from mail.

@fickle granite ^^

[inland peak]

as problematic as Flash was, it's a serious loss not to have a proper replacement. the learning curve with html5 <canvas> and JS (I guess that's the closest thing now?) is really not the same

[fickle granite]

Try Dart and Flutter. Probably very different from flash, but pretty slick

[modern sail]

There's always openfl which has all of the graphics APIs from actionscript/flash but over haxe or typescript instead and transpiled for different platforms like JavaScript/html, android, a native application, etc.

https://www.openfl.org/

[tough drift]

use wsl

[quaint tulip]

I have fooled around with the schemdraw library in Python, which would work on any operating system with Python. Not sure it would meet all your needs though

https://schemdraw.readthedocs.io/en/stable/

I used gEDA a couple of decades ago, I was a clueless student so it worked for creating some nice diagrams but it appears it is no longer maintained http://www.repo.hu/projects/geda-archive/www.geda-project.org/

This seems to be the replacement project http://www.repo.hu/projects/ringdove/

[nimble notch]

I like unix... it's just that I feel bored sometimes bcz I'm unable to get the things done... maybe if I try to work on it, It'll feel more engaging than windows

[quaint tulip]

This is the most exciting thing I did with schemdraw, which I admit is not terribly exciting

[dusky hawk]

Hi people, what are some good resources to learn about WSL or Linux in general?

[wise forge]

i like content of this book to get better with LInux. full of just practical modern stuff.
Otherwise 99% of linux users will tell you that best way to learn is just using it 🙂

[wise forge]

WSL is not linux, it is hybrid of Windows and Linux that makes Windows issues somehow being present in Linux.

[dusky hawk]

any online docs?

my zoomer brain is a bit too adhd for books tbh

[wise forge]

download the book above? and it will be online docs.

[dusky hawk]

well too bad, imma still learn wsl first lol

[wise forge]

never saw online docs for linux. People usually used Rufus to make live usb and try it at least in this way
Linux is very for practical head on experience first

[dusky hawk]

time to become a pirate I guess

[quaint tulip]

These are "standards" rather than docs but could serve a similar purpose https://refspecs.linuxfoundation.org/

[ocean anvil]

I need a good friend

[cunning pebble]

ventoy is superior

[dusky hawk]

is wsl just as good as native linux or are there any caveats I should be aware of ?

[broken forum]

it's another layer of indirection

so there are integration and performance cost

[dusky hawk]

I already knew about the performance issue. What about the integration part? Like, are there any important incompatibilities I should know about?

[vital bay]

the performance hit is actually pretty low, usually in the single digits, but it does make a difference for cpu/gpu intensive tasks. other than that, if you require systemd, you have to enable it manually. networking is also finicky because wsl NATs by default, though nowadays there is a mirroring mode that makes the distro's port visible on the same ip address as windows

[prime magnet]

it is the best you can get on Windows. Beware of things like git vs git.exe , etc

[cobalt haven]

Can anyone tell me how can i use windows .exe in my linux?

[vital bay]

you'd have to use wine or virtualization. linux cannot natively run exe files

[wise forge]

I prefer using Lutris for this. GUI manager of wines. The most lazy option for me

[wise forge]

No. Wsl is not as good as native Linux. Besides performance overhead from having Windows in background:

1. You will have at minimum weird GUI issues in anything u use in WSL
   Because it will be trying using Desktop of Windows to show stuff

2. Also weird port forwarding issues to see web stuff from wsl in your browser

3. also potentially weird networking, volume and VM issues from using Docker Desktop that was made for Windows people.
   Native performance good is only in Linux native Docker Engine, with which in WSL u get port issues

4. expect possible issues with Filesystem differences. It is always issue when distributing cross OS stuff

[dusky hawk]

should I use uv with system unit

[trail sapphire]

you can but you don't need too, there are many different ways around it

[surreal scarab]

What do we think about Debian moving to reproducable builds? It sounds like a good idea, but I'm kind of waiting for the other shoe to drop.

[fickle granite]

what do you expect the other shoe to be? It sounds like a good idea to me

[uneven arrow]

The other shoe maybe being every package needing that degree of control? Or does ubuntu provide that work?

[surreal scarab]

Apparently every package will need it.

At least by default.

[surreal scarab]

Well, I'm thinking...what then if that can then be used to not just restrict what can be run in terms of security but restrict and enforce what can be run in terms of freedom. "Sorry, it looks like you're trying to run a non-approved version of a package we use to make sure the powers that be can spy on and control you."

Call me paranoid, but there's a lot of shit going on that kind of makes me feel just a tinsy bit validated in that position, you know?

[uneven arrow]

I don’t think they’re considering end user constraints, rather that what the distribution provides is reproducible. You could also off constrained user side stuff like apple’s signed applications but such a thing would need to be totally opt in.

[trail sapphire]

i don't think you would need to worry about Debian doing something like that, it would be very much against their mission and reason for being as a project

[trail sapphire]

that has nothing to do with reproducible builds, it's just about you or others being able to verify that nothing has gone into or been modified and that their source package really correspond to the produced binary packages

reproducible builds is a good thing in my book at least

[trail sapphire]

it's just another security measure in addition to signing the packages

oh dope i just saw this

[oak shell]

this channel

[scarlet hawk]

I'd just like to interject for moment. What you're refering to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!

(sorry had to share some inaugural crappost before any serious conversation)

[oak shell]

what did you expect tbh

[tepid scaffold]

btw why isnt there a linux and mac channel?

[vestal turret]

Linux and mac are kinda unix-oid systems

[vestal turret]

macos is posix certified iirc

[uneven silo]

mac os kernel is a Mach hybrid

the name even says "X is not Unix"

[dusty furnace]

unix and unix-like systems include linux and macos. we do not have a lot of mac questions on this server, it is natural to combine the two into a single chat.

[main olive]

Shawn, but isn't the "GNU system" actually hurd?

well, the GNU system

or would that be the GNU system with hurd added (edit: makes sense, since hurd is apparently just the microkernel)

[dusty furnace]

shawn just posted copypasta

he's not, like, a GNU expert. it's just a meme :D

[main olive]

oh 😃

[scarlet hawk]

LOL hey hey who says Im no GNU expert

I sing Stallman's Free software song in my head all the time

But yes it's a copypasta but GNU hurd has never been ready for everyday use so far, theyre still working on it

Theyve been working slowly on the Hurd kernel for like decades now

When the Linux kernel came out I guess they slowed down cause they had a complete free OS useable and that was their main goal

Though Im curious to see if Hurd ever sees some real use

But no I'm not a GNU expert

trying to run pip on cloud9 i get sudo: pip: command not found

however if i run without sudo it runs, but doesn't have sufficient permissions to complete the task

[vestal turret]

you shouldnt run pip under sudo

[flint carbon]

error: could not create '/usr/lib/python2.7/dist-packages/httplib2': Permission denied

thats what happens without sudo

[vestal turret]

why are you using sudo?

[flint carbon]

trying to follow this: https://developers.google.com/identity/protocols/OAuth2WebServer#example

a lot of samples i find online seem to suggest running pip in sudo - granted many of these are old so i'm not sure if the practice has since changed

example: https://community.c9.io/t/google-client-library-python-installation-on-cloud-9/11861

i think i figured it out - running pip with --user instead

[vestal turret]

yeah,you should run as few things as possible with sudo

[flint carbon]

i understand what you're saying - but can you explain to me specifically why it WON'T run?

i understand why I shouldn't - but the fact that it doesn't run confuses me

[vestal turret]

for some things it is required

[zinc bobcat]

sudo pip is very insecure. setup.py runs for a pip install, so you're essentially running arbitrary python code as root. Due to the nature of Python package distribution, malicious code is not robustly protected against so it can be a pretty potent attack vector (as seen recently with the PyPi namesquatting issue https://arstechnica.com/information-technology/2017/09/devs-unknowingly-use-malicious-modules-put-into-official-python-repository/, but it doesn't have to be namesquatting)

[gilded basalt]

python3 -m pip install --user -U <package>

^ Ensures you are using the desired Python interpreter (can be used with pypy, different versions, etc.), installs in user space (doesn't require admin/sudo), installs the latest version even if you have a older version cached

[royal marlin]

@flint carbon you should be using a virtualenv

pip install and python care about PYTHONPATH, which is where python packages live. PYTHONPATH involves system-wide directories such as /usr/lib which users should not touch. pip install installs things in directories listed in PYTHONPATH.

When you use a virtualenv, the PYTHONPATH is modified, which causes pip to attempt to install in the virtualenv path when you use pip install

pip install --user tells it to install into the non-system directories within PYTHONPATH

Generally --user isn't what you want when working on a project. You want a virtualenv for each project. This has many many benefits, but lets talk about system coherence. When you use pip install in a system directory, it simply replaces important files from your package manager when it has conflicts, and some systems use an exec script which pip will mangle in the process of installing, and will do even more harm when uninstalling any package.

The pros? Dependency separation. Each venv can contain a different version of a package, and this isn't a problem since they never know about each other. Permissions separation. You no longer have to worry about installing a package for development (editable) because it's contained in a venv. Your system can use the stable version of the library you're working on while you can use the development version when you activate your venv.

When someone reccommends that you sudo pip *anything*, they probably want to hand you a command that they know will "just work" regardless of the side effects. In basically every single case, the thing they're telling you to sudo pip for shoud not be done. This is the domain of your system package manager. You should find the package in your system's package manager (apt/dnf/yum/pacman/portage) instead of doing sudo pip.

[gilded basalt]

^

If you want to create a virtual environment, on Python 3.4+ you can simply do: python3 -m venv ./nameofenv

However, if you're on Ubuntu, Debian, and probably a few other distros, you will need to install venv using sudo apt install python3-venv (replacing apt with your package manager, e.g. zypper, yum, dnf, pacman, etc.)

I like keeping my environments in a single directory under my home directory: mkdir $HOME/.virtualenvs

[vestal turret]

~/develop/venvs for me

[gilded basalt]

Then: python3 -m venv ~/.virtualenvs/project && source ~/.virtualenvs/bin/activate

If you're using Pycharm or Visual Studio Code, they can be configured to search that directory for environments and allow them to be selected for projects

This also works if you're using custom interpreters (e.g. pypy) or instances of CPython you've built from source

[hazy bobcat]

Is there anyone here who can help me add a email server and setup multi domains on my vps?. Currently I'm running it for only 1 website which uses flask.

.. The other dev-ops

[hazy bobcat]

oh I though since it is a linux server this was the right channel

sry

[royal marlin]

@flint carbon There are a few different options for venvs. Python 3.2+ now ships with venv in the stdlib (so it's sort-of defacto), but virtualenv has been around for a long time, is used in many python 2 projects, and just generally has many users. There are tools which build on top of these existing virtual env providers.

My favorite venv tool is pipenv (and its config file Pipfile). It does a few things for me, such as autoactivation* and hiding away the detalis about where the virtualenv is.

• I have my shell set up to look for a Pipfile when I change directories, check if a venv exists, and then activate it. This makes it super easy for me to cd project/dir/token-slinger and have the venv for that project activated automagically.

hmm, so, you should probably just pay someone to do email services for you. Unless you're intending to become a mail server admin professionally (and considering you're asking in python how to set up dkim on postfix, that option is doubtful), the immense amount of effort and ongoing new information learning required to responsibly run a mail server farrrrrr outpaces, in lost value, the option of paying someone to do your mail services for you.

[scarlet hawk]

hey here's a dumb frigging question

(this'll show my ignorance on everything hardware)

are some heavier distros rougher on battery life or does the OS on its own have a negligible impact?

Hm, Lubuntu claims to be energy efficient so I suppose it can have some impact

guess I answered my own question bye

[balmy arch]

Just to confirm - yes, they can have a big impact

[royal marlin]

@scarlet hawk the "size" of the OS is not going to affect your battery life. The features it does or does not have on or off by default is what will affect your battery life. Whether it loads a bunch of programs by default can affect your battery life. The settings and the things which need to do processing and I/O being "on" is what affects your battery life, not the "size" of your OS.

A fully-featured OS is, in fact, likely to do better for your battery life because a group with the resources to curate an OS also already has the resources to focus on efficiency and battery life compared to an OS group which is small (and perhaps produces a "small for the sake of being small" OS). A small OS does not have to worry at all about energy or battery settings in concert with other programs or settings because it is, by default, doing basically nothing. Installing things on top of it is where the "heavyweight" OS shines in battery life.

[gilded basalt]

It also depends on the battery saving features it utilizes or has available. For example, Fedora only recently started making use of SATA power link management and Bluetooth auto-suspend.

Some other examples are ACPI power states (S0-S5) and Wi-Fi sleep

[uneven silo]

your computer also has to have linux drivers for the specific management features

[gilded basalt]

Also, CPU usage levels and times can make a big difference. If you're not using much CPU, most modern Intel and AMD CPUs will dynamically reduce the clock speed to conserve power and reduce heat output. If something is regularly triggering the CPU to clock up, then there's going to be a lot of wasted power.

[uneven silo]

my asus laptop doesn't have nix drivers for the keyboard backlight

[gilded basalt]

Yeah

[uneven silo]

it recognizes the leds and whatnot, but can't actually turn them on

[gilded basalt]

Windows generally performs better than standard customized Linux distros in battery life, and a lot of that is due to better (or any) driver support

[uneven silo]

hard to believe, considering how much windows thrashes my disk and uses my cpu

with arch and i3, running sublime, 3 konsole windows, discord and vivaldi in the foreground, my cpu rarely goes over 8, and almost never goes over 15

on windows, it constantly stays at 20% or more

[gilded basalt]

Probably some pre-installed manufacturer bloatware or something you added (like AV software). The most CPU usage on my Windows machines is usually Discord, VSCode, PyCharm, and occasionally Chrome/Firefox

[uneven silo]

uh

i built my pc

tbf, its an athlon chip, but a good one

[gilded basalt]

Athlon..

Those are still around?

Huh

[uneven silo]

one of the new ones

760K

Quad core 4GHz

[gilded basalt]

When you said Athlon I instantly thought of Athlon64 😛

[uneven silo]

not one of the old mostly-pcb athlons lmao

no

nonononono

[gilded basalt]

IIRC my first PC was a overclocked AMD K6

Ah ok

[uneven silo]

k6

wew lad

[gilded basalt]

Well, also, I usually spend some time optimizing my Windows machines after I get them (as with all my daily driver setups)

So disabling services, uninstalling bloat, various setting tweaks, etc.

[uneven silo]

K6 was a good ol chip

me too

[gilded basalt]

Yeah

[uneven silo]

but arch (and linux in general) is just so light

[gilded basalt]

I had a TON of them, ended up e-wasting some of them last year

[uneven silo]

unless you have ubuntu with unity

[gilded basalt]

Fedora is pretty heavy on battery I found

My old laptop that I used back in college as a notetaker would last ~4-6 hours under Windows 8, and 10 added a hour or two to that.

Fedora would not last that long

[uneven silo]

discord eats my battery, but if its not running, my laptop can last a good 4-7 hours depending on use

[gilded basalt]

Yeah Discord is often times the most resource intensive thing on my system

Only things that match it are PyCharm and sometimes VSCode

[uneven silo]

that's why i use sublime 💙

[scarlet hawk]

Sublime nonfree [angry richard stallman]

How does one deploy a cli script that uses virtualenv for dependencies on a Ubuntu server?

[proper aspen]

I may misunderstand what "deploy" means here, but isn't enough to make a systemd unit service and call the script using the full path to the python executable inside the virtualev?

[bitter flint]

Not really. It's a cli tool that takes some arguments and processes some files. I'm using click to parse arguments and use a few other libraries to perform various tasks.

import click

@click.command()
@click.option('--count', default=1, help='Number of greetings.')
@click.option('--name', prompt='Your name',
              help='The person to greet.')
def hello(count, name):
    """Simple program that greets NAME for a total of COUNT times."""
    for x in range(count):
        click.echo('Hello %s!' % name)

if __name__ == '__main__':
    hello()

$ python hello.py --count=3
Your name: John
Hello John!
Hello John!
Hello John!

So normally, if I didnt have dependencies, I'd add a hashbang #!/usr/bin/python3 and do my thing but using virtualenvs require that mapping to some other python executable instead

Pipenv for example provides pipenv run command to run given command in the virtual environment.
So I can write a bash script mytool.sh to relay the arguments to mytool.py as pipenv run python mytool.py $ARGS

But this gets tedious when you have to maintain a number of tools on a number of servers.

So I looked for solutions, setup.py and writing a setup script seemed interesting.
But I can't seem to get it to work properly. The executable it creates (automatically) does not load dependencies/virtualenv.

[proper aspen]

let's say that click is your dependency, and if you launch your script without having your activated virtualenv the script fails.

what I was suggesting it that, instead of launching your script with
python hello.py --count=3

you could use
/path/to/virtualenv/bin/python hello.py --count=3 even if you are outside your virtualenv and it isn't live

[vestal turret]

(source /path/to/env/bin/activate && python script.py)

Would that work

() creates a subshell in bash

[proper aspen]

(test_discord) sgrc@t420:~$ chmod +x hello.py 
(test_discord) sgrc@t420:~$ nano hello.py 
(test_discord) sgrc@t420:~$ python3 hello.py --count=3
Your name: sgrc
Hello sgrc!
Hello sgrc!
Hello sgrc!
(test_discord) sgrc@t420:~$ deactivate 
sgrc@t420:~$ .python_virtualenvs/test_discord/bin/python3 hello.py --count=3
Your name: test
Hello test!
Hello test!
Hello test!
sgrc@t420:~$

didn't know about the subshell thing. Thanks @vestal turret

[vestal turret]

But directly using the venv python binary would be better imo

[bitter flint]

@proper aspen Yes, that certainly works, that's how I run the scripts on Windows, such as:

@echo off
D:\Development\python\pdftools\.venv\Scripts\python.exe D:\Development\python\pdftools\bookmark.py %*

But having to write full path to the script for every script for every machine that I use is tedious. setup.py creates an executable and places it PATH, but when I run ./venv/bin/python3 setup.py install in a virtualenv shell, the executables are created inside the venv folder. Running it with the python installed on the system python3 setup.py install gives me an error.

[languid gorge]

My discord bot run on #unix im running a #303906096458891264 bot, however it always seems to crash all my discord bots at the same time. Not sure why

[sage solar]

What happens when they crash

Any output etc?

[languid gorge]

none as im running on screen

so I never see the output @sage solar

I did make it create a discord.log tho, which has nothing in there

[sage solar]

Can your run it like

python3 bot.py > log.txt

[languid gorge]

okay will do

[sage solar]

Or did you do that in order to create discord.log

[languid gorge]

no I just ran like that

lets see 😄

[halcyon beacon]

rm -rf *

$yolo

[languid gorge]

@sage solar @halcyon beacon hey guys. That log which produced log.txt had nothing inside.

is there any other way to log a discord python3 code.

[sage solar]

If your code did any prints or error msgs exceptions whatever it should've been put inside that file

[languid gorge]

nothing inside.

the file is empty

and my bot did crash

[sage solar]

What exactly are you running it on / in?

[languid gorge]

Ubuntu 16.04 Server

1GB Ram 1 core.

[sage solar]

Hm

Should not really be a problem

[languid gorge]

I even compiled Python3.6.5 myself.

My code works completely fine of Windows.

[sage solar]

That is not a good idea usually

[languid gorge]

usually but same error using the normal way

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.6
sudo apt-get install python3-pip```

[sage solar]

Hmmmmm

[languid gorge]

normal way I would do is above

[sage solar]

I guess you sshed into it and ran the command?

[languid gorge]

mhm

using screen

I tried using nohup too.

[autumn walrus]

soft ghost voices in the distance: doooockeeeerrr

[sage solar]

And screen should stop the program from quitting once the session is closed

Stop ghosting inver

[languid gorge]

use docker?

[autumn walrus]

:D

[sage solar]

Yeah that's usually a good idea

[languid gorge]

yeah screen python3 blah.py

then CTRL + A + D

[sage solar]

You could try doing a systemd service maybe

[languid gorge]

kk never used docker yet need to look into that O.o

[sage solar]

Does the server get auto rebooted or something like that regularly?

[autumn walrus]

using screen in this day and age is a big no no imo, systemd or docker are preferrable

[sage solar]

What is the age Inver

[languid gorge]

It shouldn't do, I did consider it however I'm running a Bitcoin node which was still active.

[autumn walrus]

it's the age of containerization and microservice architecture

[languid gorge]

anyway to check last boot up? lemme google one sec

[sage solar]

Webscale ™

[autumn walrus]

no webscale was 4 year ago

[sage solar]

Oh

[autumn walrus]

uptime Zumy

[sage solar]

What did they use to webscale

[languid gorge]

who -b

[sage solar]

How does one webscale without containers and the database for big ideas

[languid gorge]

nah last reboot | less

lists all reboots 😄

[sage solar]

And?

[languid gorge]

im gonna run again and see if dates change

[languid gorge]

bot still crashed and server didn't reboot @sage solar @autumn walrus

Using scree.

[sage solar]

Try a systemd service

[languid gorge]

hi @sage solar

root@vps# python3.6 bot.py 
<discord.ext.commands.context.Context object at 0x7f106ad66198>
Unclosed client session #this happends 30 mins later today
client_session: <aiohttp.client.ClientSession object at 0x7f106c1865c0>```

that's the whole log output. I just ran normally

[sage solar]

at this point you might be better of going to #303906096458891264 #discord-bots as thats the place where the people who are into discordpy hang around

because i really have no idea whats happeniong here

[languid gorge]

yeah that's what I did waiting for a reply still

[main olive]

alright @oak shell

[oak shell]

As I said, I do not use Arch and don't know very well how their package management works and how deeply integrated Python is in a regular installation. Post your complete question here again and somebody who is able to help will see it and respond.

[uneven silo]

You should not override your system/pacman python with your specially compiled python, but it's fine to compile python and install it

[scarlet hawk]

g n u s l a s h l i n u x

[halcyon beacon]

I was asked some questions by some one

he asked me how can I use a grep to find an element int he string

normally i would use perl/python

i didnt know :/ felt bad

he also asked how can u pick an entire colum content and print that. I know it could be done in awk one one line but i didnt know either . Felt humiliated

[main olive]

[sage solar]

Grep to find element in string is just

echo "string" | grep s
Isn't it?

[vestal turret]

yes

[oak shell]

that shows you all lines containing an "s"

[sage solar]

Yes

[gilded basalt]

@halcyon beacon Well, you can still use python. Pipe the input into python script, then in your script just read from standard input with sys.stdin

[main olive]

Anyone who masters sed and awk can do anything on a Unix system :p

[halcyon beacon]

man I never use sed and awk, but I think I should look at the awk functionality to get the coloum data extracted

cuz any interviewer can ask it

in perl it takes time to do that

can you guys recommend some important SED and awk functions I should study?

[vagrant fern]

the column thing is simple, to print columns within a string just use $n, e.g. ```sh
$ echo a b c | awk '{print $2;}'
b

[weary canyon]

Is there a way to run any terminal command through a python script?

[autumn walrus]

there's a couple of options, if you don't care about getting a result back from the command you can do

os.system('run a command')

If you do care about getting the result back you can do use the subprocess module

from subprocess import Popen, PIPE
proc = Popen(['whoami'], shell=False, stdout=PIPE)
out, err = proc.communicate()
print(out.decode())
print(err)

[weary canyon]

Thanks @autumn walrus and @main olive

And is it possible to do git push <link> without having to put my credentials everytime?

[autumn walrus]

yes, by using ssh instead of http(s), how familiar are you with using ssh for git?

or rather, how familiar are you with ssh in general?

[weary canyon]

Not even a bit

<link> = https://github.com/{username}/{repo}

I use this format^^

[autumn walrus]

right, then it might get a little tricky, but I would strongly recommend getting familiar with ssh and how to use github with ssh keys

[weary canyon]

So i have to do this git remote add origin master {the ssg link} git push -u origin master

[autumn walrus]

that's a step in the middle of a longer setup process

[weary canyon]

Where can i find that "longer process"?

[autumn walrus]

oof good question, I don't have a link handy

[weary canyon]

Ohh ok

Will google it

Thank you very much buddy

[autumn walrus]

no worries, I'll also google real quick and see if I can find something that looks right

[nimble oasis]

https://gitlab.com/help/ssh/README

[autumn walrus]

github also has this https://help.github.com/articles/connecting-to-github-with-ssh/ it's a whole tutorial from end to end explaining ssh and also how to generate ssh keys and uploading them

the outcome will essentially be using git without having to use username and password as the key will handle all authentication

[weary canyon]

That's great

[oblique kernel]

stupid q of the day, I am a newbie user of Ubuntu 18.04 and I need Python 2.7 (yes, 2.7, we're stuck with 2.7 at work). how do I get 2.7 and not 3.0?

[autumn walrus]

there are no stupid question (there are some times, but this is not one) I don't have an immediate answer actually, when I ssh into a ubuntu 18 box it defaults to python 2.7.15, and I have to type python3 to use python3. That said, maybe it's as easy as doing python2 --version ?
but that's a total guess

[oblique kernel]

didn't occur to me that it might come bundled, I'll check

I just set up a linux vm on my home computer so that I'm a bit better equipped to install essential stuff on my new work box

[autumn walrus]

nice as a dev box?

[oblique kernel]

probably - we run super duper complex Python software which doesn't run locally on Windows (too many dependencies to fight) but supposedly is much easier to run locally on Linux

so far I ❤ the package managers - no more wondering where to get programs from

aha, 18.04 has python 3 bundled, but when I tried python it helpfully told me how to get it ❤ ❤

[autumn walrus]

yeah ubuntu is pretty accomodating like that :D

may I give some unsolicited advice being completely oblivious to your current setup? - it's usually a dick move but I feel strongly about it

[oblique kernel]

go ahead

[autumn walrus]

I often find myself needing to recreate my development environment, and since you mentioned you've created a vm, I can recommend looking into using vagrant, but you might already be using that?

[oblique kernel]

nope - I'm using virtualbox on a windows 7, zero idea what vagrant is, I'm gonna google 😛

[autumn walrus]

cool, in short vagrant is an automation framework that can be used alongside virtualbox (and other virtualization tech)

once you've created a little snippet telling vagrant how you want your vm to look you just run the command vagrant up and it downloads the linux image and installs and configures the things you told it to

[oblique kernel]

wow, great

[autumn walrus]

if you then go and fuck the VM up for whatever reason, you just do vagrant destroy and it deletes the vm, and you can start over (without the download process)

[oblique kernel]

I'll be sure to look it up for the next time I'm setting up the vm (hopefully never 😛 as I don't indend to do anything destructive to it)

[autumn walrus]

cool, not to toot my own github repo, but this is what I use for ubuntu 16: https://github.com/inveracity/vagrant

I haven't moved on to 18 yet because I'm lazy

the real benefit is the shared folder, so you can code on your own computer and it'll automatically sync that into the VM for execution

[uneven silo]

@autumn walrus your subprocess module can be shrunk a bit

[autumn walrus]

do tell, as I imagine it's not by putting it in cold water?

[uneven silo]

"module" i meant snippet lol

if you set stdout or stderr to a PIPE object, you can just do proc.stdout or proc.stderr to get the output (it may be bytes or str)

check_output might also help shrink it https://docs.python.org/3/library/subprocess.html#subprocess.check_output

[autumn walrus]

ah yes! good tips

[snow terrace]

kill me

I want xorg to work

I never have this issue on fresh ubuntu rolls

ITS WORKING

nvidia lts drivers

NOT

jsut nvidia

ah its broken again

[snow terrace]

I fixed it 😄

nvidia lts drivers somehow

bricked my boot

My ETI partition didn't have any more space on it at the time I installed the nvidia drivers

but

when i reinstalled them having freed up by deliting some of the "emergency images"

which i really dont need

everything worked fine

[sage solar]

nvidia drivers want EFI partition space?

[snow terrace]

well it explains why it worked after reinstalling them and cleaning up EFI partition space 😛

What actually happened

I have no idea

it couldn't mount my EFI partition for some reason after installing then i cleaned up and reinstalled

[sage solar]

nvidia should not interact with EFI

it should really not

[snow terrace]

That's why it was the last place I looked when I was having boot issues

but its all done now

There were a few bugs with EFI and nvidia interaction

reported across the web

Can I remove the boot partition from my fstab now I'm done with it? Or does Grub talk to Arch to run the EFI bootloader

I feel its kinda doubley insecure to have boot mounted all the time

I'd rather decouple it from my system

[uneven silo]

tias

if it hibernates and comes back on with boot unmounted, assume it works

[buoyant hatch]

Good ole NVIDIA drivers lol

^haven’t been on in a bit. Just saw the above convo.

[main olive]

Hey thought I'd ask it here

since its Python related and on xUbuntu

I believe I have 2.7 on my XFCE4 Ubuntu

How can I change it to 3.7

so that I can use Python3.7 on PyCharm

[oblique kernel]

apt-get install python3?

I had the opposite problem, 3 came out of the box when I needed 2

my own question, what's a good python ide for linux? on Windows I have PyCharm, but it's overkill - basically I do most stuff over ssh with vim, but I need something else for the local copy of the code - I absolutely need a folder overview AND search in files/folder function, integrated debugger is nice but not essential

The pop ups are annoying tho

[vestal turret]

I haven't noticed any annoying pop ups

[zinc bobcat]

What popups?

[finite ferry]

@vestal turret $ sudo apt-get install zlib1g-dev Password: sudo: apt-get: command not found is there any problem?

[oak shell]

What OS do you use?

[outer reef]

Mac

[vestal turret]

ah i misread that

[oak shell]

Well Mac has no apt package manager. That is a thing of Debian-based distros, like Ubuntu

I think Mac has brew or something like that? Dunno, never used one

[finite ferry]

I am using mac os mojave

[vestal turret]

homebrew, but that's not installed by default

[outer reef]

Is there a reason you're trying to make it?

There is an installer on the Python site

[vestal turret]

xcode-select --install

according to zlib issues on github

[finite ferry]

That did not work either

[outer reef]

@outer reef No . I am just trying to install python and set up an enviroment for me to write codes

[outer reef]

Then I suggest using the link I just posted

[finite ferry]

Thank you. After installing how do I start ?

[outer reef]

Have you ever worked with Python before? Just learning?

[finite ferry]

Yeah

just learnign

[outer reef]

Then I'd suggest looking at http://www.automatetheboringstuff.com and snagging https://codewith.mu/en/download

[finite ferry]

I am sorry but I appreciate your time

[outer reef]

The first link is to a book that we often suggest to people just learning, and the second is an editor that we suggest for the same reason

Is this what I am supposed to see?

[outer reef]

[uneven silo]

yall need to plug the no starch humble bundle

they got lotsa good books

[main olive]

@oblique kernel how would I get rid of P2 when I install P3 tho

[sage solar]

you dont want to get rid of python2

lots of stuff under several major linux distros wants python2

[oak shell]

rule of thumb: never remove a Python version that came preinstalled with your system.

[vestal turret]

or change python from 2 to 3 or vice versa

not all scripts may have been nice enough to specify the version they require

[oak shell]

yep, don't mess with system binaries

bash aliases are fine though (except that they will confuse you if they shadow different commands)

[faint valve]

xfce master race

kde is trash

[main olive]

I think xfce is horrible to tbh

(Both in speed and look'n feel)

[faint valve]

wtf

in speed?

maybe i can understand look argument, but speed?

[main olive]

It's better than the other 2 (talking about gnome and KDE), it's still quite slow

[faint valve]

gnome is terrible let's just keep it civil and call it MATE 😉 . but where is your point of comparison or perspective? yeah the other big ones suck, i agree

[main olive]

I use i3 and sway (for Wayland)

[faint valve]

i like i3 but to compare something like XFCE or KDE to i3 or hell fuckin' emacs is just disingenuous and you know that

[main olive]

They serve the same purpose

So they can be compared

[faint valve]

but they don't m8. it's like comparing C to Python bluntly.

[main olive]

@vestal turret I just want to use Py3.7 on PyCharm so I can continue my projects

[faint valve]

i mean just have some perspective lol

[main olive]

I use Py3.7 on Windows so I am trying to keep persistence in that regard

I cant re-write an old project to be 2.7 compatible

Mainly cause I don’t have the time

Except that XFCE doesn't offer "high level stuff" that i3 doesn't. I3 also supports the mouse, has a contextual menu from which to launch applications, notifications, etc.

[faint valve]

....and at the end computers are just adding and storing numbers amirite. all the same

i like i3 a lot too

but lol cmon

i3 can be compared to...other tiling managers

why do you think i3 is within the demographic it lives in

[main olive]

Because it's not shipped as default in many distros

[faint valve]

ok unity isn't shipped as default in many distros

hmm

🤔

[main olive]

That's why I don't know Unity, as I dislike Ubuntu

[faint valve]

well i can agree with that one

hmmm

any changes/differences between that and 3.7?

[main olive]

which is what

thats the question

like how significant it is

[vestal turret]

https://docs.python.org/3/whatsnew/3.7.html

[snow terrace]

I really like Gnome

I just like how there's a UI to do everything

Like I agree that the other options are good if you sit down and learn how to configure them in great detail

but I just... don't have that time

Or at least I don't want to spend my weekend tuning i3

What I like about gnome is the tweek tool makes everything really easy and I get a pretty windows / mac like experience and everything has really well defined hotkeys out the box and everything just works. I'm not having to install clipboard managers just to print screen something .etc.

I get that there's a lot of bloatware that comes with Gnome that really isn't preferable but at the same time, it's not nearly as bad as Windows or costs a Mac and I'm willing to take that trade

and come on now it's not slow by any means on modern hardware

[main olive]

@snow terrace agreed, gnome is mature, modern and well-rounded

there's a reason why Canonical has switched back to it

[snow terrace]

If all you want to do is have a UI that's highly customisable in an easy to use fashion and looks and functions well

gnome is the usability king

Like MATE and XFCE just don't even come close to how nice it is to use and the volume of hotkey integration that feels natural that comes out the box.

I've never spoken to anyone who liked XFCE and Mate more unless they (a) hadn't tried Gnome or (b) used massively customised window managers. And I think it's so-called bloatware REALLY ISNT THAT BAD and hugely exaggerated.

Hi

Bear with me on mobile

I have a python script that needs to run on a cron job as a regular user called webadmin. Webadmin is in Apache group, because script writes to a data file that php opens up and displays on the page. Currently the code is in /home/deploy/code in script but here’s my q for now. Does the code need to be in webadmin home directory in order to be run by webadmin on cron?

I have a few more thoughts but that’s a start..

I think that I need to create a new pyenv and virtualenv in webadmin directory because the venv using now is actually from a django install

[main olive]

yep, i ended up realizing i dont need to use webadmin right now and used deploy instead and chown'd the folder to deploy:apache and it worked fine

(Don't mind my project name, I am using an old folder to examine the code of Fsociety)

Its subject to change

This is what happens when I try to generate a Python 3.6 venv

I did do sudo apt install python-pipin my terminal

then restarted PyCharm

[uneven silo]

install distutils

[heavy warren]

How can I go about setting up a media centre on my old Dell Optiplex 380?

[sage cove]

@heavy warren what kinda of media center?

I say go simple. Minimal linux distro, simple desktop environment + VLC

that'll play literally anything.

a good 4K player would require a decent cpu though

[heavy warren]

ok, what's a good minimal linux distro? I've tried puppy and lubbuntu but both of them are eh

[sage cove]

I haven't tried it yet, but maybe Kubuntu?

[heavy warren]

I'm going to try the blank lubuntu installation (so there's no programmes on it aside from termial)

(and internet browser ofc)

[main olive]

For a good minimal distro, Arch all the way

It's a killer distro, honestly. You can make it whatever you want/need, it's a heaven for people who like to customize their system

[heavy warren]

I'm not the greatest at linux tho

so that doesn't sound good for me

[main olive]

Their wiki explains everything

I'm not joking, my mother installed ArchLinux

https://wiki.archlinux.org/index.php/Installation_guide

If you want to try 😉

Manjaro is also nice and a bit easier to install. But well, as you want a minimal installation, for me distros like Gentoo/LFS and Arch will always be better, because they don't "impose" you any software, you just have the bare minimum to survive after the installation, then you install whatever you want

And arch has official repositories + user repositories, which means that you'll probably find every software you want

[heavy warren]

"Upon installation, only a command-line environment is provided" wait what

[main olive]

Isn't that what you asked for ?

After installation, you only have a shell from where you can install anything you want, using pacman (the equivalent of apt)

If that's not what you asked for, then I don't understand your definition of a minimal distribution @heavy warren

[gilded basalt]

PSA: if you're creating a bootable OS image (e.g. installing Linux, live CD), use Etcher: https://etcher.io/

[main olive]

@heavy warren, what was the problem with Lubuntu?

oh, he left. nvm.

[deft raft]

Does pip come installed with a fresh raspberry pi I solved le issue

[gilded basalt]

Yes

[safe sluice]

How in bash I can create a script that loop in a file with IPs ssh them each of them and run different command in each?
Something like that;

cat hosts | while read -r $line
do
for i in some_commands
do 
ssh root@$line echo $i
done
done

The problem is, for each host i'm running X times and not a single time the command

how can I share the index between the loops ?

[main olive]

Did you check clusterssh ? It might do what you need

[safe sluice]

kinda looking for a solution without the need to install stuff

[main olive]

anyway, to share an index between loops, you could use a global variable, as ugly as it is

Declare a variable on top of your script and assign it to 0, in your for loop, update the value of this variable with the index, and then you can use it in your other loop

ugly, but it should work

[safe sluice]

it can be ugly - I will try thanks!

[gilded basalt]

This might be of use as well: https://unix.stackexchange.com/questions/44757/ssh-input-from-text-file

[sage cove]

@safe sluice
In bash, define your own function.
In python, use paramiko

[weary canyon]

I am trying aws, ubuntu 16.04
The problem is that when i disconnect from the terminal my script stops working!
Is there a way i can make it so that it runs even if i am not actually connected to the server

I was thinking of crontab but i am afraid that it will run the same command again while the script is already running, messing up everything

[uneven silo]

screen, tmux, or pm2

[weary canyon]

Do you have links to them @uneven silo?

[uneven silo]

pm2 is an npm package, the others should be in apt

dunno what you mean by links

[weary canyon]

Aah, i meant docs

Thanks for helping though

[uneven silo]

man

[lavish radish]

anyone on Gentoo ?

did you have any issues setting up python3.7 so far?

[uneven silo]

u building from source?

[lavish radish]

@uneven silo yes ofc, there's no *-bin (precompiled) pkg yet

[sage solar]

Doesn't using binary packages kinda defeat the point t of Gentoo?

[lavish radish]

it does @sage solar

that's not how this distro works though

[uneven silo]

there isnt really a precompiled linux package available from python.org

[lavish radish]

@uneven silo yeah but you wanna tweak it however you want, why would it be 😛

[uneven silo]

why did you mention a binary package then

are you not downloading from python.org?

[lavish radish]

I didn't mention it, you did man

not downloading it from python.org, but from portage

[uneven silo]

why lol

[lavish radish]

it's the same

that's how this system works

install it via package manager

[uneven silo]

i mean yes, but..

[lavish radish]

your question is like, why do people install python via apt 😛

[uneven silo]

no

[lavish radish]

oh

[uneven silo]

can you specify build options with portage?

or change ./configure flags?

[lavish radish]

yes, you can add them in the USE flags

from your /etc/portage/make.conf

[uneven silo]

oh it's global lmao

[lavish radish]

or local

via /etc/portage/package.use/python

and applies to that package strictly

[uneven silo]

but what about configure?

[lavish radish]

didn't try that way, but that was the old way

you can still do it that way

but no one does that anymore

[uneven silo]

uh

./configure [options] is how you setup python. Do you not compile with optimizations or anything?

[lavish radish]

I do

[uneven silo]

how then

[lavish radish]

I don't use ./configure , as I said

I check the package from portage and see the available flags

if it's optimized for my CPU et. al. then I add them to my USE

[uneven silo]

wut

[lavish radish]

you ever used Gentoo ?

[uneven silo]

no lol

[lavish radish]

ok

so in Gentoo you can tweak w/e you said with ./configure via the USE env var from your /etc/portage/make.conf

ie. add USE="vaapi amd64 X alsa"

and when you install the pkg emerge --ask dev-lang/python3-7 it compiles with those flags

you get it now?

[uneven silo]

i guess it works if configure only changes flags

[slow sandal]

Hello Guys, I want to install latest version of python3 on my CentOs 7 and i am confused on which guide to follow, some have 20 steps, others are a simple line yum install python3 , can you shed some light on how to do that?

[uneven silo]

do you want to build it from source or not?

[slow sandal]

I do not know the answer to that question as i do not know wwhat that would do for me.

I need to google what that is

[sage solar]

CentOS does not have python3 in its repositories per default so you will either have to add a repository by doing

sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm
sudo yum update
sudo yum install -y python36u python36u-libs python36u-devel python36u-pip

That would install a binary version

If you have special reasons to build from source (which you apparently dont)

sudo yum groupinstall -y "Development Tools"
wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tar.xz
tar -xJf Python-3.6.4.tar.xz
cd Python-3.6.4
./configure # optional parameters go here
make
make install

Are you using CentOS as a desktop distro or why are you asking this question?

[uneven silo]

you can get customized optimizations when building from source

[slow sandal]

ok, in my case I dont.
python36u
Isnt the latest version of python 3,7?

[sage solar]

yes

but not all major libraries support it yet

so you might be better of with 3.6

[slow sandal]

Ok, thank you

[uneven silo]

idk why they say that, unless you are using asyncio, you likely won't have an issue

[slow sandal]

@uneven silo @sage solar

sudo yum groupinstall development```
Is this neccessary/good practice to do before  `yum install -y https://centos7.iuscommunity.org/ius-release.rpm` ?

[sage solar]

what you are doing would be necessary for building from source

just use

sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm
sudo yum update
sudo yum install -y python36u python36u-libs python36u-devel python36u-pip

as i showed befor

[slow sandal]

ok

[uneven silo]

i dont use centos

[shy grotto]

it seems like psutil.sensors_battery() is returning None on my laptop with arch linux (btw) on it, yet i have a battery in there and the acpi command works just fine. i can access the battery information in /sys/class/power_supply/C23B/..., so why doesn't psutil do that?

i imagine it's just not supported by psutil.

[sage solar]

@shy grotto apparently psutil relies on sysctlbyname for battery stuff
namely

 int percent;
    int minsleft;
    int power_plugged;
    size_t size = sizeof(percent);

    if (sysctlbyname("hw.acpi.battery.life", &percent, &size, NULL, 0))
        goto error;
    if (sysctlbyname("hw.acpi.battery.time", &minsleft, &size, NULL, 0))
        goto error;
    if (sysctlbyname("hw.acpi.acline", &power_plugged, &size, NULL, 0))
        goto error;
    return Py_BuildValue("iii", percent, minsleft, power_plugged);

I'd suggest doing all of the three sysctl calls and check what they return to find out where the error actually is and then do further investigation on that

[shy grotto]

oh okay sure

[karmic vessel]

has anyone here installed postfix and tried to pipe the mail?

[main olive]

Already done that yeah

Though I just remember following a tutorial and that's pretty much it

[main olive]

@karmic vessel Where in the pipeline do you want to insert the pipe? And how do you want to connect to it? You can either add <<| command>> to aliases, or set it up in master.cf

[karmic vessel]

@main olive I don’t honestly know. But I want it to work lol so either way possible I want to try

How do I set it up in master.cf

[vivid vault]

i'm trying to manually upgrade Pip on Ubuntu, i get this error
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

on mac i know i need to run Install Certificates.command but idk where that is on Ubuntu

edit: fixed this, anybody who has the same question check this https://stackoverflow.com/questions/41328451/ssl-module-in-python-is-not-available-when-installing-package-with-pip3

(ping me pls!)

[main olive]

@karmic vessel Start at step 3 (And substitue the command invocation as needed) https://www.howtoforge.com/how-to-install-and-configure-mailman-with-postfix-on-debian-squeeze

[karmic vessel]

@main olive do you mind if i pm you m8?

[uneven silo]

@vivid vault u dont need to install certificates, because that only helps when the certificate isn't recognized. Did you read the error?

[vivid vault]

i figured it out, i edited the message with the solution i used

[sage solar]

I did a fresh fedora install on my desktop yesterday and started my PC today but interestingly ctrl c ctrl v isn't working anymore

I did some research on gpaste and other clipboard managers and it appears that it takes the stuff I tell it to copy but just doesn't paste it

Ideas?

[vestal turret]

another fresh install

[sage solar]

thats giving up

and for such a little issue unacceptable

[sage solar]

interesting

so after i reboot i can now copy paste in a few applications

hmmmmm

[vestal turret]

did you reload the files after modifying them?

[sage solar]

i did not modify files

so in google chrome i can now do
select text
copy
paste (pastes text)
paste (doesnt paste text)

in discord its just straight up not working

[main olive]

are you using X or Wayland ?

@sage solar

[sage solar]

i tried on both

[main olive]

https://fedoraproject.org/wiki/Wayland_features#Clipboard_manager

should work on X though

[sage solar]

well as i said it works partially

so I assume its either a bug, error during installation, error during update or an error in config

[main olive]

Is the "source" of your copy/paste still open when you paste ?

[sage solar]

yes

i already explained above

[main olive]

Anyways it seems that it's still an open issue on the Fedora bug tracker

I guess the Fedora team will say it's because of Wayland and likewise

so my bet is that it won't be solved before long

[sage solar]

as i already explained

i tried under wayland AND Xorg

to be precise
Gnome Wayland
Gnome Xorg
Gnome Classic
LXDE

[main olive]

Under Xorg, that's another problem, as no issue seem to be open on this

[sage solar]

yes I am looking at bugzilla myself already

well have looked until i gave up for today 30 minutes ago

[main olive]

can't test myself sadly

I hate Fedora, so.. 😃

[sage solar]

i mean i got my perfectly working laptop with fedora here

checked all the config files i could find about it

they fkin match

[main olive]

are you copy/pasting with keyboard, or with the mouse ?

[sage solar]

both 😦

[tawny sky]

On fedora and other red hat-based systems there can be a problem where your window manager is using a different clipboard to x

[sage solar]

i mean i could paste like once in chrome

[tawny sky]

Try using shift+insert for pasting

[sage solar]

like i copy
then paste (works)
then paste again (doesnt work)

lemme fire up my machine again......

nope @tawny sky

[tawny sky]

hmm

no idea, in that case

[sage solar]

grrreat

sooooo

lets see if i can make a fedora installer accept my home partition as home......

no because it has to use a LVM ofc

n i c e

[vestal turret]

you are reusing an old home folder?

[sage solar]

no its a fresh fedora install

but i just thought about reinstalling

no its a fresh fedora install

[sage solar]

so reinstalling using my hold home partition worked

yay

[hazy bobcat]

Guys how do I run a python script from cron when I need to change to a virtualenv with workon

[vestal turret]

/path/to/venv/python script.py

[hazy bobcat]

doesn't work

funny enough if I try it on console only with python I can import my library

if I put the script it doesn't import

[vestal turret]

Run a bash script that activates the env and runs the code

[cold pagoda]

Do you log the errors? say "/path/to/venv/bin/python /home/......./file.py > /tmp/cronlog.txt 2>&1"? or do the bash script thing from @vestal turret

[hazy bobcat]

It works If I do it with source to activate env

gonna try the cron now

[weary canyon]

any commands to get my static IP address?

[vestal turret]

I'm on linux ubuntu and tried to run pip to install something, and it creashed with segmentation fault. attempting to see the crash report crashed the crash reporter, what do?

[oak shell]

Can you paste the full output you got?

[severe basalt]

https://pastebin.com/v7YYJJ6Z the packages I'm installing are a little niche...

the actual crash report is crashing on open, so I can't copy it

[vestal turret]

I think it's a problem with one of the libraries

[severe basalt]

so I'm stuck trial and erroring? :/

[outer reef]

Or uninstalling and reinstalling the libraries

[severe basalt]

trying that now

ok, seemed to work, guess it was a corrupt install

[tender ocean]

Hey dudes, here with a question about some code I'm trying to write:

# Get Users 

import subprocess 
details = subprocess.check_output(['cat','/etc/passwd']).decode('ascii').strip().split('\n')
user_details = [[category for category in container.split(':')] for container in details]
users = [x[0] for x in user_details]

With list comprehension, is there a way I could combine the user_details and users into a single instance of list comprehension, or is LC limited to two sets of brackets? I'm still relatively new to Python, and I've been trying to wrap my head around this specific task for a bit.

Arguably, this could be accomplished in a much quicker way with cat /etc/passwd | awk -F ":" {'print $1'} , but the point of this project is to use Python as much as I can.

[gilded basalt]

You could nest a generator comprehension in a list comprehension

Also, why are you using cat when you could just open the file directly?

Unless of course this is through a reverse shell 😉

[vivid vault]

sorry, i fixed the problem and deleted the message but i forgot i sent more than one

[tender ocean]

@gilded basalt damn, good point man. Thanks

[gilded basalt]

Is it a reverse shell?

[tender ocean]

@cerulean pagoda What're you trying to accomplish?

[hearty scarab]

hmm... which user did you removeed ?

ls -la /lib/systemd/system/stop-bootlogd.service

My Django project on AWS EC2 cause 500 error on /registration endpoint,
Email sending cause this I think.

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
SITE_ID = 1

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = env('EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = env('EMAIL_HOST_PASSWORD')
EMAIL_PORT = 587
EMAIL_USE_TLS = True

If I change this django.core.mail.backends.smtp.EmailBackend into django.core.mail.backends.console.EmailBackend
I see result on console and don't get error
users receive activation link when register on my site.
Why email smtp email sending is causing 500 error? anyone has opinion?

os is Ubuntu16.04

[vapid depot]

If linux was as popular as windows is, I can't see why you would ever want to use windows

[gritty stirrup]

@vapid depot driver support would be great

[vapid depot]

yup

thats the reason i said if its more populAR

that way people cant say about lack of drivers 😅

anyway, they have came far in the last 2 years and with steamplay it will hopefully get more drivers

[gritty stirrup]

Ye

Hello guys. i am struggling with setting up a selenium on my CentOs 7 CLI 64 bit VPS (no desktop). I cant find an up-to-date, clear guide that shows what i need to do. From what I understand so far I need to install a 'fake' screen solution in order for any browser to run at all (even phantom js) . Then i need to install the browser and its webdriver ? Once all that is done all browser will automatically run trough the fake screen when I launch them trough python and what fake screen solution should I use ? Can anyone shed some light on this please ?

[hearty scarab]

You dont need a "fake screen". You just need a headless webdriver

[slow sandal]

so simply installing the browser (chrome for example) and its webdriver and runnign in headless doesnt require something like Xvfb ?

[slow sandal]

I got it sorted out in the end with some help fortunetly, on the bad side Its lieka tribal wisdome, I have no idea how i did it...

CentOs 7 64 bit CLI + selenium

basic webscraping

but a site uses lots fo javascript

I coudltn set up the chrome + its webdriver

I installed a bunch of stuff, made an absolute clusterfuck and got lucky that it worked...

Thx for the replay anyway 😃

I wanted to but I couldnt find any proper guide lines, every guide is 2 years old and out of date, and made for a desktop environment

chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument("--no-sandbox")```If I dont use these options, it crashes

[vestal turret]

Browsers run websites in a sandbox for a reason

[sturdy ember]

@broken canopy Try #web-development

and please post the exact error you get

saying that you got a 500 error wont help much :P

[old hamlet]

I'm using Paramiko to execute "wget -O linuxgsm.sh https://linuxgsm.sh/" but it just saves a empty linuxgsm.sh while if I execute the command via putty it works. What could be wrong?

Anyone who can help me with this?

[main olive]

Next question:

root@ubuntu:~# clear
terminals database is inaccessible

I have installed powershell from Ubuntu's shop and now I can't clear my screen

I have no idea what is wrong. I don't see any powershell lines in ~/.bashrc

PS. removing powershell didn't help

[oak shell]

I think this means you have no terminfo files

There should be files in /etc/terminfo, /lib/terminfo, and/or /usr/share/terminfo

on a real Ubuntu system stuff would be in the lib folder by default

Check if those directories contain files

@main olive if stuff is missing, try reinstalling ncurses-base: sudo apt install --reinstall ncurses-base

[main olive]

inside /etc/terminfo i have README file /lib/terminfo contains folders and files inside them /usr/share/terminfo is empty and following command did not solve the problem

maybe powershell overwrited something?

oh, now I have removed powershell, it doesn't work stil as normal user, but I is working as root sudo clear

[oak shell]

uh....

does tput init work?

[main olive]

tput: unknown terminal "xterm-256color"

[oak shell]

Check the output of ls -l /lib/terminfo/x/xterm-256color

[main olive]

it is there

[oak shell]

can you paste?

are the permissions and owner correct? Maybe it became read-only

[main olive]

you mean something wrong with rights?

-rw-r--r-- 1 root root 3525 maj 23 10:08 /lib/terminfo/x/xterm-256color

[oak shell]

that looks correct

did you turn it off and on again already?

Maybe there's just something wrong with the current session, which fixes itself if you log out and back in

[main olive]

will check

[oak shell]

or possibly even open a new terminal at least already

[main olive]

new terminal doesn't help

i go restart

[oak shell]

👌

[main olive]

nope

[oak shell]

what does echo $TERM say?

and do you use any multiplexers like screen or tmux?

[main olive]

okay, it works now, i have no idea it stopped working after installing powershell

it was a problem caused by conda

conda install -c r ncurses

and $TERM was good: xterm-256color

@oak shell thanks so 😉

[oak shell]

nice, okay 👍

[pulsar fjord]

Anyone know how to fix the arrow keys not working in Ubuntu 16, when inside the Python3 interpreter?

>>> ^[[A^[[A^[[A^[[A^[[D^[[C^[[D^[[A^[[D

instead of last line or moving cursor.

[cold pagoda]

Did you see this? Seems like they're dealing with Python 2, but the problem may be similar. https://stackoverflow.com/questions/893053/seeing-escape-characters-when-pressing-the-arrow-keys-in-python-shell

So, pip install readline should do it

[pulsar fjord]

Had more issues than just that. Instgalled 3.7 and its all better 😃 Cheers.

[weak skiff]

any1 know why I would get this error using pyautogui on ubuntu?
maim, my screenshot app of choice, is installed.

NotImplementedError: "scrot" must be installed to use screenshot functions in Linux. Run: sudo apt-get install scrot

the python code that causes that error is this

top_right_slot_empty = pyautogui.locateCenterOnScreen('images/top-right-slot-empty.png', grayscale=True)

[oak shell]

did you read the error message?

it tells you all you need to know

[weak skiff]

I tried to but don't understand why maim isn't used

when pyautogui supports maim https://github.com/asweigart/pyautogui/blob/master/pyautogui/screenshotUtil.py

running which maim on my machine returns output /usr/bin/maim so i shouldn't need scrot

[oak shell]

hmm, I see

looking at the code, https://github.com/asweigart/pyautogui/blob/master/pyautogui/screenshotUtil.py#L153 is weirdly indented

so unless maim depends on scrot somehow, I would consider this a bug

However, I don't know about either tool, nor pyautogui

You should probably write a bug report as GitHub issue

[weak skiff]

I see, thank you!

[mortal plinth]

Oh man

I wonder how many problems have been caused by Python2 and Python3 both being aliases python

Like my VSC keeps trying to pip install things with python2 and then lint using python3 ,

[main olive]

you can specify the version

[zinc bobcat]

That's probably why PEP 394 exists https://www.python.org/dev/peps/pep-0394/

[quaint mirage]

just had a weird behaviour with bsd-mailx

only from cron tasks though 🤔

something akin to mail -s "[ABC] Somesubject" root will work fine from the term

but the moment it's triggered as a cron it removes the square brackets

I assumed it was evaluation or w/e

but when escaped it produces an email with the subject "\[ABC] Some Subject"

idk, just seems odd that it's only from cron tasks

¯_(ツ)_/¯

[mortal plinth]

@zinc bobcat if only everyone was disciplined :(

[gilded basalt]

Is there a way to register some sort of callback when a executable is run or process with a particular name is created on Linux?

E.g inotify but for processes

Ideally what I'd like to do is register a callback for when a process is created and another for when it dies

[oak shell]

@gilded basalt what is the expected run time for the process? Long enough that polling for the start is possible? Monitoring a running process and doing something when it dies is rather easy, IIRC, but you'll have to get to know the PID at some point...

[main olive]

Since you cannot use inotify on /proc, I think you'd have to do some kernel dev 😃 Or a daemon, which would be the simplest

Or net link + proc connector, you can Google that

Seems like you can retrieve events about process creation, exit, etc

[gilded basalt]

Thanks guys

Expected runtime is not possible to know

Polling the processes regularly is my current thinking, however that's less than ideal. It takes more resources (process will wake regularly) and there would be a lag before I'm able to display the process is alive and start pulling data.

[weak skiff]

how do I go about installing python 3.7.1?

on ubuntu? Right now I use python3.7 by running sudo apt-get install python3.7

when I do apt-cache search python3.7, only packages about 3.7 show up. when I use apt-cache search python3.7.1, nothing shows up. i did python -V to verify that I am indeed running 3.7 atm

is it just too soon for it to be available in the ubuntu/debian repos?

[vestal turret]

They favor stability

[weak skiff]

ah 😃 well thanks for the heads up.

[oak shell]

@gilded basalt Well, what do you know about the processes you are looking for?
