Sandboxing in Linux is completely broken

I read [flatkill.org](https://flatkill.org) and there is something that I found interesting since I am looking into securing apps with Apparmor.

>Almost all popular applications on flathub come with filesystem=host, filesystem=home or device=all permissions, that is, write permissions to the user home directory (and more), this effectively means that all it takes to "escape the sandbox" is `echo download_and_execute_evil >> ~/.bashrc`. That's it.

Since apps store configuration in hidden files in the home folder, and they store those files everywhere, it is very hard to sandbox apps so that they don't try to do anything funny with hidden files in the home folder. I tried sandboxing Atril with Apparmor and it tries to load a lot of hidden files of unrelated apps. How it is possible to sandbox apps if they touch each other's configuration files?

I've just released a new version of my slack-IRC gateway

https://github.com/ltworf/localslackirc/releases/tag/1.7

This version adds support for the new strange and undocumented token type that appeared on slack that projects on the internet seem to be struggling with.

It adds a systemd service that helps people who use several slack chats to configure several instances more easily.

CudaText 1.96 vs other Linux editors on huge lines

CudaText 1.96 was [released](http://uvviewsoft.com/cudatext/) with reworked support for huge lines.

I was interested how some Linux editors handle such huge lines. Tested several editors on Ubuntu 19.10 on Intel i3 CPU. With XML file with a single line of length 4M. XML file contains line like <id name="nnnnnnnnnnnnnnn"> with the huge "name" length of 4M.

* CudaText 1.96. Opens file: 1.5sec. Caret moves at the end of line: very fast (<0.1sec). Editing of this line: not fast, adding each char: about 0.5 sec.
* Sublime Text 3. Opens file: 2sec. Caret moves at the end of line: each Left/Right arrow is 0.5 sec delay. Editing works.
* Kate 19.04. Gives colored panel "The file ... was opened and contained lines longer than .... (4 096 characters). The lines were wrapped and document is set to read-only mode...". Caret moves at the end of wrapped doc: fast. Editing is disabled.
* GEdit 3.34. Hanged of loading file (from command line and from editor), waited it for 20sec.
* Emacs 26.3 GUI. Opens file: 1sec. In word-wrapped mode. With the statusbar error "Internal error in rng-validate-mode triggered at buffer position 10. Stack overflow in regexp matcher". Pressing Ctrl+End to move to end: editor hanged with "wait" cursor.

Having a hard time understanding the hype for Pine Phone

It's from my understanding that we already can flash Linux OS into Android phones. Is this hype more of a celebration that a company is deciding to go full linux, or is there any actual benefit of using a Linux OS with the Pine Phone over a better specced Android one?

No audio recording possible? (however, my destiny is to be the best youtuber ever though)

Hello,

Yet another reddit noob that yell for help. And yes, I have been stuck for months, and yes, I have tried anything I could find on the web. My brain will get absorbed by a black hole soon if I cannot overcome this problem.

I desperately need to find the solution to be able to create viral videos and be able, in a few months, after I create my channel to have more subscribers than Pewdipie and T-Series ***REUNITED***.

&#x200B;

*And here is the problem*: I cannot record anything from my computer. Using my internal speaker, or a headset connected to bluetooth, or the same headset connected via a jack, or a new microphone connected via usb: NO audio is captured via any software whatsoever! If I open a sound recorder, or an application to "display" sound like ingot, I see nothing when recording.

I tried on the windows partition and had no problem.

It used to work fine, I used to be able to skype flawlessly.

&#x200B;

How could I follow my path to fame and fortune, without your precious help? **How could I troubleshoot this to be able to record sound?**

&#x200B;

&#x200B;

Here are some info about my system, if that can help:

Syncing podcasts between iOS and Linux - ideas?

Note - this isn’t a support request, I’m looking for ideas or suggestions.

I’m in a somewhat untenable position of using iOS for my mobile device (I’ve got no intention of going back to Android anytime soon, please don’t suggest this) and Linux on my main laptop.

When I used to have an Android I could use gPodder on the phone and on my desktop, but having an iPhone makes this impossible because no iOS apps can sync with gPodder.

Has anyone else ever figured out a way to use an iOS podcast client with a desktop Linux application, could be a media player etc? I’m using Spotify as a workaround at the moment but I don’t like their interface for podcasts.

I bought a new HP laptop and installed POP OS on it and well my results are a little mixed.

So I'm in the process of trying out Linux again and before I install anything on my main rig I wanted to try it out again on a cheap laptop. POP OS being my preferred to try right now.

Well POP OS installed okay just one problem is that the Wifi didn't work. Apparently my WiFi card was the realtek rtl8821ce and that one apparently has issues with Linux from what I read. I could get the Ethernet to work but that kinda defeats the purpose of a laptop in some regards.

So I did try to install a realtek driver for my laptop but nothing worked. If I can't get it to work I'm just gonna return the laptop. Any help is nice.
