Hey everyone! I currently have an antenna which is a realtek chipset (yuck) that I had to load the drivers myself. Even though I loaded the drivers from this github repo and keep them updated, I'm still getting issues like constant common disconnects, slow speeds (even though on my mobile connected to the same network I may get 6 times the speed), etc... I think I'm ready to pay up and get an antenna that has proper support in Linux, and I found this one after a little bit of searching online: official alfa link.

My question is if this is actually well supported, or even if there is something better I could get (without making me even poorer). What do you guys think, and what are your experiences?

Thanks!

Edit: came back here after a while to edit in case someone comes upon this in the future. I ended up ordering this one: AWUS036NHA fron Alfa. It has the ath9k chipset which is included in the kernel, so it seems like a good choice. Will try to remember to come back after I get it and try it put to give my comments.

Hello everyone.

This semester at uni I'm taking a course which requires me and my group to create a complete software project. Out of the available topics we chose to make an airline ticket booking app, much like skyscanner.com. It is my responsibility to handle the majority of the coding aspect of the project, so I would like your advice.

I would like your thoughts and recommendations on what frameworks/languages/technologies you recommend we use to implement the project. I would like to avoid anything complicated that will take a long time to learn, as I only have a limited number of weeks to deliver. However we do need to be able to have a decent looking frontend, a backend that will allow users to login either as passengers or administrators (them being the ones who manage flights and handle passenger accounts etc.), and passengers should be able to at the very least input a departure city and time, and arrival city and time and get a list of available flights back (the flights don't need to be real-world flights, we can generate that data to simulate the app).

I've checked out pythons flask, but (correct me if I'm wrong) while simple it seems too much so. I would need to handle user authentication, creating and connecting any databases etc. all manually from pretty much scratch. I'm interested in finding that middle ground of simple enough to get up and running with quickly, while not so simple where I need to learn 1000 other things just to get a prototype up and running.

Thanks in advance for your suggestions!

Edit: I asked my professor for advice and as he suggested I decided to go with bootstrap and sqlite. Im still open on suggestions to do the authentications though :)

Hey everyone.

Basically I need to do what the title says. I did have xfce4-power-manager installed and had it set there (had the setting disabled so that it wouldn't suspend after inactive), but xfce4-notifyd was creating problems with dunst which I installed and setup last night, so I removed xfce4-power-manager and xfce4-logind.

However now after a few minutes of not doing anything my PC sleeps. There must be a setting somewhere I can edit which is the same thing xfce4 uses to implement this, no? Either a file or another power manager software which will not cause problems with my dunst.

Thanks in advance for all your help and suggestions!

Hello guys.

This semester at uni I'm taking a Network Fundamentals course which is basically Cisco's Introduction to Networks course (we're literally doing just that). Im wondering how applicable and if so in what ways it is to real life situations where one might want to setup their own home network. I realise that if you don't use cisco equipment the commads will be different, but if we consider the fundamental knowledge, will what I learn doing this course help me in the future when I will be setting up my own "server room"?

Thanks! 😁

Hey everyone. As the title suggests, I use bspwm, with xfce4-power-manager and sddm installed. I have the power manager setup that I can hibernate/suspend (still a bit confused as to the differences between the two but its besides the point) everytime I hit a button on my keyboard to "sleep" I get the popup below:

I'm not aware what application is stopping the sleep, nor if it is something I should worry about, but if I click Yes then my system goes to sleep. Hitting any key after that wakes it up, without me having to enter any password. I know there is software I can install and setup to do that function, but I was wondering if there is any way I can configure xfce4-power-manager to use sddm as the "locker" program, so that it takes me to the sddm login page when waking.

Thanks in advance!

Edit: I just tried to sleep and this time this is the popup that appeared:

Basically the title. Is there anything that my instance admin needs to do so I can login?

Hey everyone. So Last night there was a general problem with my building's network connectivity. This morning my landlord let me know it was fixed, which it was. I verified this from my mobile phone as well as the laptop I am using right now to write this post. However on my fairly new and hence barebones desktop running arch, I simply cant get NetworkManager to connect or even in some cases see any wifi networks.

This morning, it would occasionally show me the available networks, I would try to connect to my one which would work, but I would for all intents and purposes not have internet until a few minutes later the connection would drop. Now it doesn't even show any available networks.

Below are the outputs of some commands I thought would be useful. Of course it's probably not a comprehensive list so please do ask if you would like me to run and show the output of another command, just know I need to redirect it to a file and then transfer it here with a usb so its a bit tedious.

EDIT: At the opoint after my wireless interface where there is (EDIT) written, in the actual output there is written NO-CARRIER, BROADCAST, MULTICAST, UP enclosed in angle brackets, but for some reason I can't figure out how to get markdown to render the angle brackets. I think it thinks I'm writing HTML.

EDIT 2: Solved this by getting help from the arch linux forums. Link to my post where I got help, in case future people need help.

Hello everyone. I wrote this command in the terminal directly and got the desired and expected output - that being the last 50 occurrences of me installing or removing a package with pacman or yay: history | grep -e 'pacman -S\s' -e 'pacman -R\s' -e 'yay -S\s' -e 'yay -R\s' | tail -n 50 > ~/history_installed

I now want to make this runnable as a script for obvious reasons, but when add it to a script and run it I get the following error: /home/user/.bin/check_installed.sh:fc:3: no such event: 1

Here is my entire script:

#!/bin/zsh

{history | grep -e 'pacman -S\s' -e 'pacman -R\s' -e 'yay -S\s' -e 'yay -R\s' | tail -n 50} > ~/history_installed

Note: /home/user/.bin is in my path. Verified by successfully running another script in there from a different location.

Please help me figure this out if you could. I am running zsh with oh-my-zsh. Thanks in advance!

Hey everyone. So I am running bspwm with sxhkd, and while keybindings set by default work (i.e. super + enter opens terminal which I changed to alacritty) I can't seem to be able to add any new ones - at least that will work.

I've looked into it extensively and the majority of the posts seems to be talking about locales and keyboard layouts, but I can't seem to find anything wrong with my ones (of course I only have two eyes, so your input is appreciated). The classic is the super + space trying to run the program launcher, in my case rofi which does nothing (running rofi -show drun from terminal directly works correctly). Here is the output of the localectl status command, but of course I will provide output for any you request:

$ localectl status
System Locale: LANG=en_GB.UTF-8
    VC Keymap: uk
   X11 Layout: gb

My .xinitrc contains the following lines:

...
localectl set-x11-keymap gb
systemctl --user import-environment DISPLAY
...

I start bspwm from my .xinitrc, and sxhkd from bspwmrc using the following line:

pgrep -x sxhkd > /dev/null || sxhkd &

Any ideas on what I can do? Any commands you need me to run? As I said in the title, I'm at my wit's end.

Thanks in advance!

EDIT (ADDED CONFIG FILE LINK): https://pastebin.com/uknPbrjj

Edit2: came back to say after a system update it just works normally

Hey everyone. I'm thinking of maintaining an iso for my setup once I have that the way I like it. I wouldn't publish it so it would just be for me.

How easy would that be to do? Would it just be a case of rebuilding the iso every week/month to get the updated packages in it, or is there more to it?

Thanks!
