grep then pipe to wc -l
lavish hemlock
SSH key and TOTP is overkill lol
rustic sky
for some people, yes
joseph@cactus:~$ sudo zgrep "Invalid user" /var/log/{auth.log,auth.log.*.gz} | wc -l
105824
SSH key is not overkill by any means
on every host I operate the first thing I do is completely disable password authentication
dusk shadow
SSH keys are preferred, but i don't use them, but i should.
lavish hemlock
zgrep?
dusk shadow
zgrep is used to serach zipped files
hence the leading z
there are a few more, like zcat etc
lavish hemlock
@rustic sky Each time i use that command, it goes up by 2?
dusk shadow
people may be trying to get in now, trying a bunch of passwords, if it's from the same IP, you can block them, but that seems kinda futile
but, if you wanted to, you could try something like ufw reject from <IP> to any, just make sure that your not blocking a valid IP of course (like your own 😛 )
rustic sky
Ohhhh I know why it's going up lol
dusk shadow
sudo
rustic sky
because when you run sudo command it logs something like ```
May 29 01:20:49 cactus sudo: joseph : TTY=pts/0 ; PWD=/home/joseph ; USER=root ; COMMAND=/bin/zgrep Invalid user /var/log/auth.log /var/log/auth.log.2.gz /var/log/auth.log.3.gz /var/log/auth.log.4.gz
yepi don't get it
rustic sky
lol
rustic sky
it's searching for Invalid user
dusk shadow
it's telling you that someone ran sudo, which should be of concern if it wasn't you
rustic sky
yeah
lavish hemlock
i feel kinda ashamed from a google instance
really
i would expect them to be more secure than anything
dusk shadow
sadly, there's no global bad IP list, they are leases generally.
so if a bad person has it today, a good person could have it tomorrow
and vice versa
lavish hemlock
why can i not just block anybody that doesn't have a home directory in /home
rustic sky
it is doing that
lavish hemlock
oh
dusk shadow
i think he's saying he's in GCP
and why goesn't google just block these malicious users
magically
rustic sky
yeah, chinese proxies
lavish hemlock
yeah
rustic sky
don't ban china
dusk shadow
pwn: you can also add 2fa if you want
rustic sky
just setup fail2ban
rustic sky
yes
dusk shadow
for Ubuntu, there's a guide here : https://ubuntu.com/tutorials/configure-ssh-2fa#1-overview

If there's a way to setup login with my yubikey i'd prefer that @dusk shadow @rustic sky
lavish hemlock
Yeah i must of read it more than a 1000 times lol

Guys im using linux Ubuntu but for some reason when I use shortcuts while playing a game it exit the game screen,I updated ubuntu but its still happening,pls if you know anything about it help me,thx
safe remnant
For some reason, why does the tkinter look so bad in ubuntu
It makes me cry
😭
:sobs:
past raptor
@safe remnant use gtk+ its much better
lavish hemlock
Yes it is running @main olive
Is it because i'm sshing to a remote server using PuTTY
how does the remote machine know i have my yubikey in
Do they mean sshing locally?
main olive
@lavish hemlock the challenge-response architecture means it does not need to be coupled to function, and the server (issuing the challenge) and the client (with the yubikey) can be separate and function over IP, like how you log into your Google account using a yubikey
lavish hemlock
Ok

I seen it on a video
honest pasture
i'm moving hosting of my discord bot from a windows pc to a raspberry pi. i want to relaunch the bot as soon as it crashes
on windows i used a file containing a goto loop around a command to run the file
how would i do this in unix?
main olive
proper answer? you set up a systemd unit
otherwise, while true; do [bot command here]; done
alternatively, don't write code that crashes
honest pasture
it's the best way of keeping it up in case something goes horribly wrong
main olive
doesn't rewrite restart the bot on its own @main olive
?
rewrite?
more recent versions of discord.py
put it this way
idunno
i had the same question years ago and as far as i remember i was told to use rewrite
i've never really used discord.py
run() will restart the bot once it catches any exception
@honest pasture
it should at least
main olive
yeah you can try raising an exception inside of any method
with raise keyword
run() is supposed to still continue working and not just exit out of
script
vagrant rune
@honest pasture discord.py has reconection logic implemented, so you'd want the process not to die
You could spin up a container with docker and run it with the option --restart unless-stopped
with that, your container will always restart if it crashes unless you manually stop it
fresh saddle
If you don't use docker you can set restart on failure on your service
vagrant rune
or use a process manager that controls your docker container

$ bash
bash: venv/bin/activate: No such file or directory
what could be causing this? its not in ~/.bashrc -- this happens any time i open a terminal or shell.
main olive
Doesnt happen in other user. Must be another config file somewhere
I suppose its time for a new user account if things are this messy... if anyone has any idea where to look lmk
I ran diff on the .bashrc in home to another users starter rc file. Its not there
fresh saddle
~/.bash_profile maybe?
main olive
from cat /usr/share/doc/adduser/examples/adduser.local.conf.examples/skel/dot.bash_profile I discovered this...
# When a normal (non-login) bash(1) shell starts, the following files are
# sourced:
#
# /etc/bash.bashrc - run by bash(1)
# $HOME/.bashrc - run by bash(1)
While other things are sourced in a login shell as told by that file, those are the only things that should happen from simply bash.
There is no bash_profile or equivalent though. I think the problem has to be in the etc fs, possible a permission thing maybe? I was editing user/group permissions and possibly by accident targeted the wrong things... idk, thats speculative since it doesnt explain the behaviour.
I will look
I think I am going to scrap this user acount and reinstall. I have learned a lot about better management of things since I installed this and its a mess now anyway.
drwxr-x---+ 2 root root 4096 May 30 19:32 virufac/
I undestand everything this says except for the + at the end
My next project I think is going to be automating my Linux system with python to be organized and backed up and better. I tend to make a mess on my own that I have to clean up when i play with new things.
main olive
usually people automate on linux with bash
not python
bash is basically whats loaded when you open a terminal in linux, so you better put time into learning bash basics
as to your question the + at the end means Access Control List and think of it as extension of already existing permissions in linux
its barely ever used but the purpose is the same, to set permissions on an object (file in this case)
like which user can access the file, which one can modify it and etc
it's considered additional and optional
so you never really see a plus here often

Does anyone know how I can upgrade sqlite3 from version 3.22.0 to the latest version, 3.32.1?
This order, for some reason, didn't work:
sudo apt-get update
apt install sqlite3
sqlite3 -version
= 3.22.0
It'll say ''sqlite3 is already the newest version (3.22.0-1ubuntu0.3).'' - but that's untrue - since sqlite3's latest version is 3.32.1
fickle granite
well, that's probably the latest version that your release of Debian or Ubuntu has made available.
Often there are alternative apt repositories with newer stuff in 'em; read up about your distro to see
restive helm
(I'm using Ubuntu 18.04)
fickle granite
ow
that's ... ancient
you know your distro is ancient when there's an LTS version that's newer
yeah, unix admin makes for the sad
restive helm
I got it cause you know.... they told me its... you know... stable 
fickle granite
oh it's stable jerry 🙂
at some point they'll drop support for it, and it'll be really stable 🙂
I think 20.04 is the new LTS hotness
restive helm
So..... you recommend me updating my Ubuntu version?
fickle granite
you can poke around the web site to see which version of sqlite that includes.
restive helm
to 20.04? Do you think that will fix this sqlite3 problem?
fickle granite
dunno if it'll fix it; and even if it does, I can't advise you about upgrading, since I know neither the costs nor the benefits (apart from the one possible benefit of getting the newer sqlite)
you can poke around the web site to see which version of sqlite that includes.
to see if at least that 20.04 incudes the version you need
restive helm
Thanks doc 😎

Anyone aware of a terminal spell checker? I want something that I can use such as:
sc thign
and it return the probably word that I meant , or maybe a list of them
when searching i'm finding stuff for vim , ispell etc, but I don't think this is what I'm after
trail grove
this is the closest one I know of that I've used with pretty good success https://github.com/nvbn/thefuck
digital haven
thanks, i meant for actual english words though, rather than console commands
fickle granite
I don't even know of a good one for files 😐
queen merlin
@digital haven Checkout aspell
it can spell check text files, but that also means you can redirect into it as well
with < ... or maybe pipe to it
digital haven
Can it run as a terminal command as I mentioned?
queen merlin
if it isn't there by default you can probably get it with brew
fresh saddle
By default IJ generates shell scripts with the shebang /usr/bin/env bash, is that really safe to use? Because I did a quick browse through the Linux standard thingy, I found that the shell should be in /bin/bash but nothing about env
wooden night
@fresh saddle env looks up the command based on the PATH,so it will adapt to wherever bash is installed on this machine.
fresh saddle
Well yes, I know that, but for compatibility reasons, which one is the best to use?
wooden night
Well doing it that way ensures bash could be elsewhere?
fresh saddle
I mean, is there more distro that don't have bash in bin than distro that don't have env is usr/bin ?
Because env is not part of the standard
wooden night
I'm not sure.
gilded basalt
If you want maximum backward compatibility use /bin/sh
That will work on systems without bash that use other shells
fresh saddle
Well, I'm using bash only features, so I need to use bash not sh
gilded basalt
If you're targeting bash specifically using env is best practice
main olive
on most systems, bash will be in /bin. but not all.
fresh saddle
And env will always be in /usr/bin?
main olive
from what i've seen over the years, overwhelmingly yes
fresh saddle
Okay gotta use it then, thanks!
digital haven
how can i operate on the output of ls ?
for example, ls | grep -v <something>, I'd like to be able to treat that like find <stuff> -exec <do stuff>
main olive
why do you need to operate on the output of ls?
digital haven
idk, i wanted to delete some stuff i guess, in this instance
main olive
ie, why do you need ls over globbing?
generally, it's a bad idea to operate on the output of ls
digital haven
because there are multiple matches to remove
a single to keep
so I'd like to be able to do ls | grep -v match -exec rm {} \;
obviously that won't work
formal schooner
use find
formal schooner
find . | xargs -n1 rm
or something like that
digital haven
-> % ls | grep -v DE | xargs -L1 rm seems to do it 🤔
you can also have inverse globs
oh ok , hrm
formal schooner
find -not -name '*DE*' -delete
i think that works too
you'd have to look up the specific syntax for gnu find
digital haven
i could use egrep and give a pattern, but i didn't wnat to bother writing them out
find -not, nice, didn't know about that
formal schooner
much safer in case you have weird malformed filenames
find in general is safer than ls
ls is for visual display only imo
if only because you can do more "inside" find
without having to pipe bad filenames around
but for 99% of use cases it doesnt matter
digital haven
find makes more sense, it's what i'd usually use for this kinda thing

I'll explain more, but you can read through this screenshot. I might need to switch my PATH, not sure. But I also am getting interesting Warnings when trying to install this virtualenv, and trying to get to installing a Django project
Please Help. thanks so much
main olive
@quaint gust don't use sudo pip
use the --user flag instead
using sudo with pip fucks up permissions
quaint gust
@main olive
Okay, so I should do:
pip3 install virtualenv --user ?
main olive
may i ask why you're installing virtualenv in the first place?
python3 comes with venv built in
python3 -m venv
quaint gust
@main olive
hmmm, isn't it needed to use Django or Flask?
main olive
no
those don't even technically require venv
it's just that using venv makes it all much easier to manage
but yeah, they also work with regular venv
quaint gust
I ran into erros trying to install Django, but also Python 3 in different areas, but mainly I am following this blog now and it says to install virtualenv, but I also thought you have to install a virtualenv to run Django and flask
main olive
nah
blog might be dated a bit
virtualenv used to be very popular some time ago, but it's been mostly replaced with the built in venv
quaint gust
Okay, well what do I do with the built venv? how do I know tha tis installed?
main olive
check out python3 -m venv --help
it tells you what you can do
here's a tutorial as well
quaint gust
Check out the bottom line after running that

stray marten
guys, doing a > b is the same as b < a?
main olive
and a < b is the same as
< b a
stray marten
right?
main olive
no
stray marten
oh
fresh saddle
That's a weird notation 
main olive
that means that the output of a is directed to a file named b
main olive
if you want the output to be the input of another process, you use a | b instead
main olive
FIFO is a file
stray marten
so here u are crating a FIFO
main olive
a first in first out named pipe
main olive
you are sending the contents of the file FIFO (the pipe) to be the input of sort
stray marten
the input of sort to be written on FIFO¿?
main olive
there should be more to this
some other process should write to FIFO as well, so sort can read from it
stray marten
mkfifo FIFO
sort < FIFO &
ls -l > FIFO```i dont understand the mid line
stray marten
ah
main olive
which sort then reads in the background
main olive
yes
stray marten
so FIFO has something and sort can sort it?
main olive
basically yes
main olive
well, it's a named pipe
stray marten
so after doing
ls -l > FIFO the output comes from FIFO?
FIFO is what is printing on stdout?
main olive
that just writes the output of ls to FIFO. unlike a regular file, FIFO is emptied as it is read (first in first out)
stray marten
i cant do ls -l > FIFO twice
stray marten
oooh
main olive
because sort stops reading after ls stops writing
stray marten
so by doing sort < FIFO & i just make a new program that is blocked cuz FIFO is empty
main olive
exactly
stray marten
by the moment FIFO gets something, that program works, and it returns 0
stray marten
yes, but once he gets input
u said i need to do sort < FIFO again
just doing mkfifo FIFO, what is FIFO? i mean
it cant do anything
main olive
sort stops reading and starts actually sorting the input after it gets EOF from ls
stray marten
just wasting memory
main olive
it's just a special file
main olive
haha, nano is waiting for something to write to FIFO
open another shell and do id > FIFO
stray marten
wait what?
main olive
well, nano is trying to read the file, but just like sort, it blocks until something writes to it
stray marten
ah yes
but i need to update the nano shell
i did cat on the onther console
i dont understand
tawdry sonnet
So I'm looking to try linux mint, but there's some windows programs that I need to study, so I think my best option is to run a virtual machine.
I have no experience with a vm, but aside from performance, is there any notable differences between installing mint on a partitioned drive vs a VM?
main olive
VMs are generally far more sluggish than running it on real hardware, at least from personal experience
with some notable exceptions, like GPU passthrough, but that's not something you'll probably do/need to do
oh, you said "aside"
my bad, can't read
tawdry sonnet
Yeah performance is my concern. I'll be running vs code on it and doing all my programming.

has anyone successfuly ran an alias defined in .bash_aliases with subprocess
the stack question gives the answer for when all the aliases are defined inside .bashrc
what if i've got all of mine in .bash_aliases tho
😔
formal schooner
sounds like you just want to write a shell script and run it from python...
i assume it involves either invoking bash with -i or explicitly sourcing the file somehow
.bash_aliases is nonstandard btw, its a convention but its not read or used by bash itself
main olive
yeah i was tryna wing it and try to get the aliases from .bash_aliases to be imported with subprocess but didnt work out
i will write the script in bash
then
thx
main olive
now aliases only work when expliticly mentioned inside of script
tool="myalias"
$tool arg1 arg2
but when importing from string, it doesn't recognise the alias no more
stable shale
I think this is where I ask questions. Either here or discord.py because it's a discord bot but I think it's an OS question -- not specific to the discord.py
Snippet is in pastebin https://pastebin.com/DtnamGYi
The code is supposed to get a filename from the dictionary, generate a temporary filename for a directory, make the directory, and copy the filename into the directory. The function works ONLY if I comment out the chmod at line 17. From tests, the directory exists all the way up to line 20 (using os.listdir()) to check the contents of the directory. Once I switch to the command line and do a ls on the destination directory, however, the newly created directory isn't there.
gilded basalt
You should probably use shutil.copy2() instead of calling cp: https://docs.python.org/3/library/shutil.html#shutil.copy2
main olive
yep... your current code has a (unintentional) command injection vuln
gilded basalt
I have no clue what tempfile_get_candidate_names() returns (presumably a string), but it looks like tempfile is doing some stuff internally that could be messing with things
It may be easier to just use tempfile.mkstemp() and specify the directory you want the tempfiles to be kept in via the dir argument
stable shale
From what I can tell... tempfile.mkstemp performs cleanup and I wish the directory to persist until cleaned up by an outside process, which is why I used _get_candidate_names and made the directory myself.
and I thought there was a reason I didn't use shutils but I can't, for the life of me, remember. Still doesn't explain the chmod issue, though.
gilded basalt
Unlike TemporaryFile(), the user of mkstemp() is responsible for deleting the temporary file when done with it.
so it won't delete the file or the directory
stable shale
chmod still needs to work because mkdtemp creates a directory that " The directory is readable, writable, and searchable only by the creating user ID."
gilded basalt
I'm curious why the directory isn't being created in the first place
Maybe try running ls as root to see if it's a permissions issue
stable shale
the directory DOES get created. I put a "print( os.listdir( destination ) )" at various points (after the mkdir, after the chmod, and after the message about the file being copied) and all places showed the new directory. When I switch over to another shell and do a "ls -lart destination" the new directory isn't there.
and if I comment out the chmod line, the directory persists after the function ends.
That's whats got me stumped
stable shale
It's almost as if the python process doesn't like the 775 permissions
main olive
should be fine
775 has the execute bit for all fields, which is what directories definitely need
so i'm actually kind of stumped on this
stable shale
You and me both. If I don't chmod the directory, everything is created (755) but since I need group writable, I tried to chmod it and boom, the directory disappears, no errors, no traceback, nothing
main olive
wtf
the process via analogous shell commands works fine, i presume?
oh, wait
@stable shale
you os.mkdir/chmod the temptag dir in /var/www/dl/{temptag}, but try to copy your file into /dest/{temptag}
i'm guessing you forgot to change it in the command
stable shale
No, I forgot to "hide" that dest=/var/www/dl
main olive
ID LKE THIS
stable shale
Ok. It has something to do with the permissions. I wonder if it's got something to do with discord.py. But if I change the chmod to 755 instead of 775, the directory persists
and if I set the chmod to 750, the directory persists AND has the 750 permission mask
and if I set chmod to 770, the directory disappears... so somebody somewhere has an issue with me setting group write on a directory created in a python script.
main olive
strange
stable shale
very
and yes, if I do the chmod in the command line, it works just fine, directory doesn't disappear, etc.
main olive
it seems to work as intended on my machine
stable shale
so it must be something in the discord.py structure
That's the only thing that I can think of that's different.
formal schooner
!d g tempfile.TemporaryDirectory
shy yokeBOT
formal schooner
!d g tempfile.TemporaryFile
shy yokeBOT
formal schooner
easier to use than the lower-level mkstemp
that said you have a very weird problem and i have no idea either...
fresh saddle
There's also NamedTemporary*
stable shale
It's only easier if I didn't need the directory to persist after execution. The only reason for using the tempfile routines is to get a unique, meaningless, nonstandard name without having to roll my own naming routine.
anyway, I'm just going to have to work around it. If the desired group id is changed in anyway (either explicitly with a chgrp in the code or implicitly with the setgid bit in the parent directory) the directory disappears when the function exits if the directory is also given group write. If I leave the group write off or if the gid of the directory isn't changed, the directory remains post execution. I do not understand it but there must be something weird in the setup the admins did. Some supposed security feature or something.
main olive
that's really fucking odd
i can't get over this @stable shale
i have no idea why this is happening and it disturbs me
stable shale
Yea.. makes no sense to me, either. I've done a few experiments and that's what it boils down to. The script is from a discord bot I'm tinkering with and that's one of the context commands. The script is running, right now, under my user account and it expects the directory to have my UID/GID (the main GID, I'm in the other group, too, but it's not MY group) if it has write permission.

serene eagle
how do I find where my files are installed in ubuntu?
because I can't find it
Because I installed 2 discords
warped nimbus
Which files?
serene eagle
The discord files
warped nimbus
I actually do not know where specifically Discord installs to unfortunately
On linux anyway
You can use find to look for it
serene eagle
hmm then what about other files
serene eagle
oh didn't know that's a command
serene eagle
discord
discord/common
These are the first two lines
So it's installed in a folder called discord?
I think I got it
warped nimbus
My guess would have been it's in ~/.local
warped nimbus
If it's an executable file, just type the file path into the terminal and press enter
warped nimbus
Depends on which file manager you use. I don't know what Ubunu comes with
But in the terminal, you can just cd to the directory
serene eagle
i'm using the terminal
warped nimbus
then ls to list the files
serene eagle
yeah I cd into it and did ls
but I'm trying to open the folder
If I know what files are in it but can't edit them
it defeats the whole purpose
warped nimbus
You don't need to open a folder to edit the files
You can do it from your terminal
warped nimbus
Are you trying to edit a text file?
warped nimbus
rm deletes files
warped nimbus
rm -r can delete a directory
Just be careful with those commands cause they permanently delete files
serene eagle
alright thanks
pulsar bane
also you could try whereis discord next time
serene eagle
find works just as well
Was able to find where the files are located
a folder called snap
pulsar bane
what find gets you may be differenbt
serene eagle
yeah whereis is a lot more precise actually
warped nimbus
Keep in mind it only searches certain, common/standard locations
Find can search anywhere
pulsar bane
^---this is true
but also one shouldn't manually try and delete files to "uninstall" something either
warped nimbus
Most of the time whereis is adequate
I agree, if discord was installed with a package manger
But some closed source apps have their own installers that do whatever
serene eagle
I am back on windows
but yeah it works
I was able to delete one of the discords
I can't delete the other one though
but it's fine
pulsar bane
i am not even sure how that happened
serene eagle
Does anyone know the issue here?
I'm not sure what It means by root folder
and it's Import Error btw
main olive
it doesn't say root folder
it says you need to be root, ie the root account (as in, you should probably run it with sudo)
and importerror is thrown when there's a failure to import a module
main olive
you probably want your venv to persist though
so you should use the -E flag with sudo
sudo -E python3 script.py or whatever
main olive
just tells sudo to not nuke the current environment
btw, explainshell.com is good for explaining flags like this
serene eagle
ah alright thanks

can i secure my MySQL server besides password?!
main olive
secure against what?
a good starting point is to go over your sql users' permissions
and see whether they're the minimal required - ie, if your front-end only reads from a database and never writes to it, the user for it shouldn't have write permissions
further, going over your sql queries in your code to see whether you've got potential for SQL injection (so looking out for string concatenations or other formatting shenanigans) is a good idea - any statements with user input should be performed as prepared statements

Is there any resource for best practices in setting up Python on Linux? I am trying to make a setup on Raspbian that I can SSH into for Python remotely. I struggled a bit before on my own since there were complications to where pip was installing things vs where Python was installed, and it wouldn't recognize what pip installed.

@sweet leaf I haven't used Raspbian in at least 5 years 😦 Is there more than one version installed?

@main olive How do i change a users password? SQL Wave?
dusk shadow
@lavish hemlock I'm not sure I fully understand the question, do you want to change the password of an SQL user using Python? If so this might help: https://stackoverflow.com/questions/56648034/how-can-i-change-password-for-sql-login-to-database-using-pyodbc
lavish hemlock
@dusk shadow i am not using python
dusk shadow
oh, just in MySQL or something?
lavish hemlock
Ya
dusk shadow
assuming you have root maybe something like ALTER USER 'userName'@'localhost' IDENTIFIED BY 'New-Password-Here'; ?
er, assuming you have root on the DB, not the linux machine
dusk shadow
@lavish hemlock np, hth 🙂
sweet leaf
@dusk shadow Yeah it's got Python 2 and 3.7 installed by default? All I know so far is that I need to uninstall Python before reinstalling since you can't just update Python
dusk shadow
@sweet leaf so, you are trying ot use python3, and when you pip install something, it still reports the error?
sweet leaf
no, I haven't done anything yet. It's just in the past I have had trouble with getting pip installed things to get recognized in Python
dusk shadow
@sweet leaf if so, you need to use pip3 instead of pip, which is not intuative (for me at least, i ran into that a bunch of times)
sweet leaf
I'm moreso trying to learn the proper way of doing things before I try swapping things around
dusk shadow
if you have both versions installed, just remember there is pip for python2x, and pip3 for python3x
which was very confusing for me.
sweet leaf
so I should probably uninstall Python 3 and Pip3 first
then try to reinstall the latest version
dusk shadow
ehh, generally python3 is better, but if your running stuff on your pi, and the distro comes with py2, i dunno if i would.
b/c most other people that are developing code for the pi would probably be using py2, but if it comes with both, then that would be fine
sweet leaf
it comes with both
but I have no knowledge in Python 2 so I'm learning in Python 3
I'm just thinking it makes more sense to be on the latest version
dusk shadow
then that's fine. I wouldn't generally upgrade 'just because' just becuase you may have to install from source or something
and then you may have your package manager version and your source installation
sweet leaf
oh I was going to just go with whatever is on APT
dusk shadow
yea, that's should be fine generally
but apt may not have the newest, and upgrading to the newest might not always be good
sweet leaf
that's a good point
ok maybe I just won't touch what's already prepared on Raspbian and just figure out venvs instead
dusk shadow
if you want to just do development, you could try spinning up a VM with whatever version of python you want, a lot easier to recover from terrible things in a VM than on an actual platform like the Pi
also, if you have a windows machine, I am really enjoying visual studio code then install python in your windows box (assumign you don't need python for windows for any reason) very nice dev environment for me.
sweet leaf
yeah probably. I'm doing it mainly for learning how ssh works and whatnot
an idea was to use an iPad to SSH into the Pi remotely to use Python when I'm not at home to use something else
dusk shadow
A VM might be better for learning that, you can try more mainstream distros
also, for the pi, if you haven't already, checkout adafruit, they have lots of cool things you can do to addon to the pi GPIO ports, like LCD screens with buttons etc which you can then program with python
sweet leaf
Cool, I'll look into it
I want to get a proper Python setup going on the Pi first so I can remote into it
Probably not the easiest way to setup Python, but it feels worth learning
dusk shadow
that should generally already exist, if it already comes with py2 and py3, your good to go 🙂
sweet leaf
yeah I'll just learn how to setup venvs to manage the packages
hopefully that'll solve any pip package issues
dusk shadow
are you having an issue with pip now?
sweet leaf
not now, but the last time I tried on a VM I did
basically the pip package wouldn't get recognized
since pip was installing to some location
that the default python installed wouldn't recognize
it was weird
and I tried pip3 too
dusk shadow
oh, the only other thing i recall was trying to use an external file, and trying to just import that, rather than calling the full path
dusk shadow
hrm, you shouldn't have to do that, but if you get it again, post it, i'm sure someone can help, I haven't seen that kind of problem in awhile, but knowing altinstall and venvs is never a bad thing. 🙂
you can also try python3 -m pip install <package> which should generally work.
sweet leaf
Yeah that resource looks like it should explain everything
I'll go through that when I try setting it up

summer trail
@serene eagle I believe xx was saying that if you don't know for sure that sudo is required, you shouldn't use sudo. Using sudo somewhere where you didn't need to can lead to really difficult to debug issues, like config files or directories inside your home directory being owned by root - and that's to say nothing about the security issues of running untrusted code as root, or the fact that root can break an operating system in a way that a regular user can't.
sharp tapir
I think this question fits here?
When I use Pexpect on ubuntu, every expect or sendline leaves gibberish in my terminal, not as a response but actually in the command line and I have to delete it every time, anyone know why that might be happening?
code is
import pexpect
import sys
import signal
def makeserver():
child = pexpect.spawn('bash Server', encoding='utf-8', logfile=sys.stdout)
child.expect('Server started')
print('Success!')
return child
child = makeserver()```thats not gibberish
it's an ANSI escape sequence, probably trying to draw colour
whatever is drawing your prompt doesn't seem to be supporting it
but it should work fine when executed as a script from a regular shell
@sharp tapir

hey guys I want to ask a general question here. I am not really satisfied by the answers from google.
Why linux sucks in gaming? You write your game in C or C++ or whatever and compile it for both platforms windows and linux. What can go wrong unless you use OS specific calls like write read?
humble onyx
I am not sure if I word things correctly but what is keeping developers from using POSIX standart library calls like fopen instead of direct system calls like open(I know they are just wrapper around the sys calls) for example?
main olive
wrappers are slower
There's nothing wrong with Linux that would make gaming less suitable for it
^
people just dont do it
But it has a much lower market share (for desktop PCs) so publishers and studios just don't put resources towards supporting Linux
because why would they, if no gamers use linux
dead loop
but steam proton exists now :3
humble onyx
so is it all about wrappers being slower so they have to use direct syscalls?
main olive
i mean thats why
somewhat
but like
xx said
so few people use linux for gaming, why bother?
humble onyx
I am interested in low level programming so I just asked myself. They have the source code why not compile it for linux as well. I underestimated the power of direct system calls I guess.
main olive
i mean also file paths
there's all sorts of things that are different
and i mean
there are cross platform game dev sdk's
main olive
I am interested in low level programming so I just asked myself. They have the source code why not compile it for linux as well. I underestimated the power of direct system calls I guess.
@humble onyx
it's not about compiling. Most games are written with such a level of abstraction that they can be compiled for Linux no problemo with minimal tweaking. The issue is actually providing support for an OS which they wont get much money from
you have to pay more for QA, testing, extra development time, etc
Most dev studios find there is no point

Hello I'm trying to convert my bash script into a python script as a fun way to learn it, this part of the script it identify which linux package manager the user is using and install the packages using the appropriate one, how could I do it in python? ```declare -A osInfo;
osInfo[/etc/debian_version]="apt install -y"
osInfo[/etc/fedora-release]="dnf install -y"
osInfo[/etc/arch-release]="pacman -S --noconfirm"
for f in ${!osInfo[@]}
do
if [[ -f $f ]];then
package_manager=${osInfo[$f]}
fi
done```
warped nimbus
Create a dictionary for those 3 values
Then you can use pathlib to check if each file exists inside a for loop

thanks Mark I'll give it a shot

I've made a simple python script that repeats a specific task every X seconds for Y amount of time. i've now added arguments for X and Y with argparse but i don't know how i would name the arguments and the flags.
is there a standardized unix-way on naming them? i know that watch uses -n --intervall for the interval, but i can't think of other programs that would have X and Y
main olive
int = interval?
time = time to repeat?
warm raft
def main():
while True:
task()
time.sleep(X)
t = summonTask(main())
sleep(Y)
t.killTask()```kind of runs like this

any reason you're using --flags and not positional arguments?
warm raft
no, i just prefer flags

I'm looking to create a PKGBUILD package. But my package contains some systemd services (and timers) that needs to be run as root so I wanted them to be placed in /etc/systemd/system/name.service, but this place is owned by root, and when you install a package makepkg -i PKGBUILD you are required to run that as non-root. So what do I do then? 🤔 . I've looked at other PKGBUILD files on the AUR and fx. Docker is placing it in /usr/lib/systemd https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/docker
warped nimbus
Don't they run with root by default?
main olive
makepkg -si escalates to root as needed
warped nimbus
You can also specify a user in the service units
Do you only care about the location for semantics?
plush sparrow
Yes.
arh thanks @main olive
What will happen when I install it via the packagemanager then? 
I suppose pacman will be fine because I run that with root privileges.
but fx. yay I see being problematic.
I need to plookup the install command inside package() I think it doesn't do what I think it does 
main olive
yay also escalates to root as needed
plush sparrow
arh nice
well then that's a good solution I think.
time for some man install
it tried to remove the service with what I had written lul
main olive
👍 rtfm is always a good idea
plush sparrow
yeah but I didn't know what to lookup, then I just tried man install and what do you know 
I think my mind is damaged:
-D create all leading components of DEST except the last, or all components of
--target-directory, then copy SOURCE to DEST
It works, but I don't understand why.
I have 2 services and corresponding 2 timers.
# Install the systemd files
install -D -m 644 "${_content}/etc/systemd/system/${pkgname}.service" \
"${pkgdir}/etc/systemd/system/${pkgname}.service"
install -D -m 644 "${_content}/etc/systemd/system/${pkgname}.timer" \
"${pkgdir}/etc/systemd/system/${pkgname}.timer"
install -D -m 644 "${_content}/etc/systemd/system/some-name-notify.service" \
"${pkgdir}/etc/systemd/system/some-name-notify.service"
install -D -m 644 "${_content}/etc/systemd/system/some-namenotify.timer" \
"${pkgdir}/etc/systemd/system/some-name-notify.timer"
this seems unnecesarrily bloated.
oh yes.
install -D -m 644 "${_content}/etc/systemd/system/" \
"${pkgdir}/etc/systemd/system/"
instead of all that, that's what -D means 🙃

ill have to watch that @plush sparrow what specifiically did they touch on if you have the moment to share salient points (i prefer to read than watch long drawn out conversations about technology) lol

It's merely a chat about old times and parts of Ken's life.
Unix history I would say.
Since it's Ken's history hehe
But keynotes:
ken's early days before bell labs, multex, unix, pipes, grep, chess.
spice whale
@humble onyx If you are interested in low level languages you need to simply go teach yourself assembly and be done with it, code theory relating to machine languages is too difficult to explain to a person who is literally just interested because the dynamics of making literal register calls and the mileau of special use cases of upper and lower level register calls (im still learning technical conventions sorry if i dont call them by their proper names) are extremly complex in theory and practical use cases.
IF you are able to develop a sense of parsing control for ascii commands you may be able to learn to parse ascii or utf-8 or utf-16 code respectively directly into machine readable scripts or executables (although i personally have much more success with parsing this type of lanugage to an interpreter than literal logical coding)
Either one are powerful options
The question is simply this, what are your development goals, do you want to make games, do you want to make databases and do database analysis, do you want to work with ai and make neural networks, do you want to work on code for theories sake and be a business analyst for a company sharing technical insights with high level programmers and explaining to the business people what they should fund to improve their bottom line
The choice is yours, but you have to make a decision about where you are going, not just following a whim and interest. It has been said before that this field is for the career enthusiast but we all must learn to pace ourselves, this field is super interesting and it is easy to get burnt out.
Not my wisdom there but goal setting is
Hopefully that helps give you some insight into what you should do with yourself if it doesnt you have some hard thiniking about which direction in life you want to go and what your goals should be for the next 5 - 10 -15-20 years.

Is there a straightforward guide on the Python website on how to install the latest release 3.8.3 in Ubuntu?
I can't find anything explaining how to install it, the Python website downloads just point to a source package. I was hoping for something straightforward like how the Node.js website points you to specific instructions on how to install in Ubuntu.
If that's not the case then any opinions on the most straightforward way to install? 3.8.2 is installed by default, system package managers seem like a mess (like omg how many packages do you really need to install to get python 3.8.3?)
Maybe I should just use pyenv or Docker?

you shouldn't touch the system python installation
you might accidentally break OS internals by manually upgrading

@spice whale Hey thank you for the answer. I know x86 assembly and low level stuff I am personally doing this kind of things for quite a bit. I just didn't know that games need OS features for optimization so it isn't easy to write a portable smooth game.
I've never developed a game neither do i want to lol
main olive
why are you ignoring my responses @humble onyx
it is not difficult to create games which are portable
those OS features are abstracted away from any game developer
humble onyx
I am not ignoring your responses sorry
main olive
via the library/platform/etc what they happen to be using
humble onyx
somebody said that library calls are slower
so developers targets a specific platform for marketing
main olive
they're not slower to such a considerable amount that it would somehow affect gameplay
like, even something like virtualizing entire function calls within games using Denuvo et al adds only slightly noticeable overhead
humble onyx
@humble onyx
it's not about compiling. Most games are written with such a level of abstraction that they can be compiled for Linux no problemo with minimal tweaking. The issue is actually providing support for an OS which they wont get much money from
@main olive What do you mean by support then?
main olive
Interaction with the GPU, for example, is in most games handled by the graphical runtime they use, such as Vulkan. Vulkan handles interacting with drivers (which is somewhat OS specific) all by itself, which means developers don't need to worry about that.
By support I mean that they would still need to do QA etc for each platform they release on. That costs money. It's an useless use of money if nobody's going to be playing on Linux anyways
Not just for the release itself, but every future patch, library updates, etc
the business overhead is much more significant than the technical overhead :)
humble onyx
Developers can compile the game for any platform with the help of high level abstraction it is not that hard at all but it requires time and money even for a single dolar it is a waste of time if nobody is gonna be playing on linux is that what you are saying?
main olive
pretty much
the amounts are of course higher than a single dollar but yes, that's the gist of it
humble onyx
okay now I totally get it thank you

How would I copy the first few letters of a file. I need to copy until 4 numbers.
So like this: file: Vogt2017_ehhwjqn-E37dhdb
Copy: Vogt
patent osprey
Yes
tiny lava
just slice it, since strings are indexable in python
patent osprey
So the whole problem is that I have 1000 .pdf’s and I am making a bash script to kinda sort them
This is what I have so far and I have to manually type in the first few characters of the file to get it working
I want to automate that
plush sparrow
📸
patent osprey
Any ideas?
frank sorrel
Are you using python to copy the first 4 letters?
patent osprey
No I am not
This will be a bash script to do everything
If I can somehow use python in a bash script then that would be ideal
formal schooner
read -r -d'' PY_SCRIPT <<EOF
import os
print(os.listdir())
EOF
python -c "$PY_SCRIPT"
recommended? no. possible? absolutely
you can use heredocs and shell parameters as a low-rent templating engine
formal schooner
more sanely,
echo Vogt2017_ehhwjqn-E37dhdb | head -c 4
But the problem with that is that it won’t work for what I need
formal schooner
even better
filename=Vogt2017_ehhwjqn-E37dhdb
echo ${filename:0:4}
then what do you need?
formal schooner
i thought you just needed the first 4 characters
patent osprey
No up in till the 4 numbers
formal schooner
so this is output from a command like ls or find?
formal schooner
and what do you want to do with the output?
patent osprey
I think I have an idea
formal schooner
e.g. you can do something like this
get_authors() {
while read filename; do
if [[ "$filename" =~ '^[[A-Za-z]]([0-9]{4})' ]]; then
echo "${BASH_REMATCH[1]}"
fi
done
}
find ~/Downloads/ -type f -name '*.pdf' | get_authors
Can’t do the [0-9] because it won’t account for _ and - and / etc
I think what I could do is make a variable and count up until I get a number
Then print out that many characters
formal schooner
well that isn't what you explained
so you want until the first 4 digits or the first underscore or dash?
patent osprey
Here 1 sec
formal schooner
get_authors() {
while read filename; do
if [[ "$filename" =~ '^([[:alpha:]]+)(?:[0-9]{4}|[_-])' ]]; then
echo "${BASH_REMATCH[1]}"
fi
done
}
find ~/Downloads/ -type f -name '*.pdf' | get_authors
but you just said it doesn't account for dashes and underscores
you mean you want dashes and underscores if they come before the first 4 numbers?
formal schooner
ok. then at this point you just have to construct the right regex, you can see the general method above
patent osprey
Yes I can finish it, thank you
formal schooner
^([A-Za-z_-]+)[0-9]{4}
maybe this
patent osprey
I will try that
formal schooner
check it with https://regex101.com/
patent osprey
Will do
formal schooner
and refer to the bash regex manual in case you end up using something that works in PCRE and not in bash https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html#Pattern-Matching

Hi, I think this is the right channel for this question.
So, even when I'm in a virtual environment, pip is running from my global environment (is that the right terminology?)
Running xubuntu out of a VM. when I say which pip I get the path to pip in my virtualenv. But when I actually run pip, it runs globally. If I set PIP_REQUIRE_VIRTUALENV=true in .bashrc and activate the virtual env, it won't even let me run pip. So it's obviously not running pip from my virtualenv. Anyone know why this is?

Is ok when reversed(my_str) sending me address of memory ?
surreal scarab
@hollow linden If you're running linux in virtualbox with w10 as a host, I'd say that you need to use the w10 drivers in w10 and use an appropriate setting in virtualbox to piggyback off the Windows side of things. You probably only want the linux drivers or ndiswrapper if Linux is what you're booting into in the non-virtualbox sense.
hollow linden
Oh so if I wanna dual boot linux I need ndiswrapper right?
surreal scarab
Not necessarily. Aim for the linux native drivers first.

Hey, sorry if this is the wrong place to ask, but I was wondering if anybody is familiar with running Python code directly inside of a BASH script...I was thinking of using a here-doc...is that even possible?
the snippet of Python is this, and it works perfectly in Python 2 which is what the old system I'm writing this for is running:
import csv
with open('test.csv', 'wb') as csvfile:
filewriter = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)
filewriter.writerow(['lastname', 'givenname', 'email', 'telephone', 'citizenship', 'company', 'birthdate', 'birthplace', 'gender'])
filewriter.writerow(['J', 'D', 'dj@c.com', '1231231234', 'CA', 'Company', '197X-XX-XX', 'France', '1'])
filewriter.writerow(['M', 'C', 'cm@c.com', '4564564567', 'US', 'Company', '1996-XX-XX', 'Canada', '1'])
Oh I see
surreal scarab
If they don't exist, or don't work or whatever, ndiswrapper is your fallback.
I don't see why you couldn't run a py script with an invocation of the main python executable in bash.
@prime gate
prime gate
the main thing is that I sadly need all the code to exist within a single file
surreal scarab
Aha.
Off the top of my head, you could extract data to somewhere writable.
Then run it.
prime gate
I think this can be done with a here-doc, but I've never tried it and just wanted to see if anybody had
a Google search yielded no results actually, but maybe I'm just searching for the wrong thing
surreal scarab
I've seen something similar. Storing binary data in a bash script.
Seems you can echo/pipe stuff into python in bash and it'll work.

huh, I actually found this page...one of these approaches might work:
https://stackoverflow.com/questions/2189098/embedding-short-python-scripts-inside-a-bash-script

(please mention me when replying)
rn the only thing i figured out how to do is move windows based on cursor or key presses

@elder orbit I actually dont know much about compositing window managment
whats like... the core feature?
elder orbit
the window manager can manipulate the windows in any way, using stuff like opengl. transparency, shadows, animations, etc need a compositor, or a compositing wm
one example is the compiz wm
elder orbit
any ideas?
i am asking because everyone seems to use XRender, but XRender doesnt seem to be availible in python xlib
but i seen someone saying that it can be replaced by opengl
but not really sure how
(like, all the examples i seen used XRender)

@elder orbit take a look at the Qtile project it is a window manager built in Python. You might be able to get involved
If nothing else you can read the source code and work it out for yourselve.
So I guess it's up to you. You can re invent the wheel or get involved with that.
I have heard good things about Qtile

I am not clued up on the differences just I know this project exists and thought maybe you should check it out as you might not need to start from scratch or you can see how they do things. Just bringing it to attention if it is not what you are looking for leave it. I

Calling Linux GNU/Linux or GNU+Linux is insanely stupid
not just because of the practical stupidity of saying “GNU/Linux” all the time
but also because the whole debate about including GNU in the name is fueled by hubris and jealousy
no other open source project demands there name in the name of another project
and yet GNU repeatedly asks that
neglecting the fact that many systems run linux kernels a lot of which have no GNU software whatsoever
Whats next X11/KDE/GNU/Linux or Wayland/KDE/GNU/LINUX
I hope this struck a chord with the 2 people who actually call it “GNU/Linux”

@main olive i call it GNU/Linux because i like to acknowledge how the majority of my command line environment, and large portions of my career, depend heavily on GNU software
it's equally baffling how eager people are to reject GNU for this or that reason
stallman's ego is not a good reason imo
main olive
A lot of my work needs tool that use x and wayland
should it be x11/linux?
personal significance is this test then
formal schooner
no, also why do you care so much
formal schooner
🤷 if X was meant to be an operating system but instead got tacked onto someone else's kernel and everyone basically forgot that X was X it would be different
i'm not saying GNU or the FSF did everything or even many things right...

We can agree that there are some scenarios where calling it GNU/Linux is justified
but there are a ton where it isn’t
formal schooner
yes, for example my and most people's linux systems are certainly GNU-heavy
main olive
true
formal schooner
the world runs on GNU Coreutils almost as much as it runs on Linux itself
main olive
but honestly no other open source project begs to be pegged onto the name of a system so much honestly
formal schooner
no, but no other open source project is currently run by richard stallman except emacs, and emacs as a project doesn't need the ego validation
well i guess stallman is out
formal schooner
his reputation was already kind of in the dumpster tbh
main olive
yeah really
formal schooner
i think a lot of people were very eager for a reason to cancel him
main olive
why should a significant app need to have to be part of the name though
formal schooner
because otherwise it gets no acknowledgement

meh
