I was bored, so I created a simple yet powerful, fully modular terminal-based code editor. Even for saving files, you need to plug in the "save" module—haha, enjoy! I made the code easy to understand, so even beginners can create their own modules, like syntax highlighting for a particular language.

How does Linux handle input devices like microphones and webcams?

When using the Gnome Camera app, I was prompted if I want to allow the app to access my webcam, but when I used my browser (Firefox) to access my webcam I was prompted by Firefox it self, but not my system.

Similarly, when any program (that I know) uses my microphone, I can see this in the taksbar of Xfce using the PulseAudio plugin. Nonetheless, I never got asked if I wanted to allow access.

Now I wonder, how does Linux handle these devices? I assume that there is not one universal response, but what I think that there is probably a layer between the direct OS access to the devices and the programs access to said devices, for example with PulseAudio. I am also interested if and how secure this really is.

(This is my first post on this subreddit, please let me know if this post does not fit here.)

SOO-DOO or SOO-DOUGH?

When pronouncing sudo, do you pronounce it as SOO-DOO or SOO-DOUGH? I personally pronounce it SOO-DOO because it used to stand for superuser do, so put the pronunciations of the 2 words together, SOO-DOO.

"Porting" Realtek's EQ Presets

Dunno if this is the right place to ask but it's been bugging me for a while to mimick the audio quality Realtek HD manages to produce on Windows using EQ presets, particularly the 'Powerful' preset, via EasyEffects with PipeWire on Linux with little success on my part. I managed to get close to getting it, however, sound gets screechy in some places while lacking enough clarity in others, unlike that crisp and bassy EQ preset.

Secrets, tips, and tricks from experienced audiophiles are welcome and very much appreciated.

Where do i find guides on configuring aerc (the terminal mail client)

Hey,

I want to make a switch to aerc from thunderbird to me more efficient with my email workflow.

I've chosen aerc and I can send and receive emails fine but I'm having trouble configuring it.

1. I want to do things like: setup notifications
2. change storage location of my email
3. remove plain app passwords from config and move to something more secure, etc

but I cannot find any guides or even good documentation on aerc.

Also where does aerc save my mails by default? Or it fetches headers everytime and then fetches mails by default?

Are there any resources I can consult to configure my aerc.


Any help is appreciated, Thanks

Arrows/Delete key produce characters in Debian 12

Working in a fresh VM, first time using Debian. In the terminal, when I press the arrows up, down, right, and left, it generates ^[A^[[B^[[C^[[D. The DELETE key also produces characters.

Any idea how to get my arrows, delete key, etc to work?

Meow! this is basically a cat like utility that uses Neovim

Before asking, there's two cool things I can think of when using this:

Neovim lua configuration, allowing to a lot of customization (I think);
Easy to change colorschemes to use with Neovim (it does not use some plugin manager, it just clones a repository and source it, but it's lua! you can add a plugin manager if you want). here's the link for it: repository

Funny story

So I was just starting out with linux today, I dual booted kali and ubuntu on one ssd with windows on another, however, try as I might, I could not get my tethered usb connection to my phone to be stable. After attempting a numerous amount of fixes and solutions, I fixed everything by moving the usb cable from one of the front ports to one of the back ports of my pc. I was almost about to give up, but luckily found a situation.

What options Linux have for Memory Isolation?

Many years ago in 2012, I was studying QNX in college and we saw a lot of advantages of it. One in particular was memory isolation and dedicate CPU. Now, I was studying TEE (Intel SGX) and I understand one of the advantages is memory isolation, something that I understood QNX solved long time ago now could be possible in Linux only by using specialized secure hardware.

I saw this as a negative aspect of Linux, secure research is aware that whatever process with privileges can hack other process by accessing its memory. I am not sure if QNX solution is 100% trusted, but I want to know fi Linux is doing something or considering something for this problem.
