Video streaming software?

Hello all - I don't know if this is out of scope for this sub, but I have a somewhat unique problem to solve. I have a closed environment that currently uses multicast to push video stream feeds to computers within the closed environment. I've been working on a project to get the video out of that network for sharing to a remote site but it has had its own set of challenges.


What I'm trying to find now is if there is a server software that will allow me to ingest the existing multicast streams, then provide a webpage/GUI where an external party can log in and view the streams individually (or, ideally, in some form of multiviewer) rather than trying to force the video stream itself out of the network. If anyone knows a software like this that would work, I'd greatly appreciate the information! Also, I need a software that can run on a virtual machine, as we don't have the space to allow for new hardware. Thank you so much to anyone that can help! (Crossposting as well)

Arch Vs Mint

Hi, I want to change my OS to either Linux Arch or Mint but cant fully decide yet..

I'v been watching a lot of videos and reading a lot of people opinions about arch / mint, advantages and disadvantages but cant decide..

I have experience with slackware linux server, I'v installed and used on it php, mail, ftp, dns, web and more.

i wanna know how hard will it be for me to use arch linux as someone with experience on slackware linux.

mint installation is gui mostly if im not mistaken so its shouldnt be a problem at all, but arch is more freedom as people say but also people say it can just brake in a middle of nowhere thats why i cant decide which one to install as my main OS.

im planning to game, watch videos, use apps like discord / spotify / netflix and etc, based basically.

i wanna know your thoughts and opinions about either arch or mint. thanks for all the answers!

Second monitor in kiosk mode?

There's some inexpensive monitors that are on the cusp between raspberry pis and PC accessories. For the latter it's mostly system status - temperatures, network traffic, etc. I know at least one of these screens has a windows app that provides this information.

This should be easy to do on a Linux desktop, right? Alas I was a novice X-mage in my youth and could (and did) set up multiple independent sessions at the time with the introduction of DBus and Wayland all of those skills are now moot.

So the question is how can I set up a separate Wayland session? (Or separate X and Wayland sessions). It's fine for it to be in kiosk mode and locked to a browser - I don't want to raise my X/Motif skills from the dead!

I can immediately rule out the obvious solution - simply adding this monitor to my set of displays. I tried that but the system got very confused with three displays - in fact it would only show two until I explicitly added the third. I have a 4-port video card and I will use 3 displays sometimes but it requires some care-and-feeding. With two displays I'll often drop from "join" to "mirror" after an idle period but everything is predictable. With three displays it seemed to shuffle the content in unpredictable ways.

(This may be due to this being a pretty old video card, probably dates to shortly after 4k/30s was first available.)

In the worst case I can use a dedicate RPi - and may need to do that anyway if I can't have the video card support separate Wayland/X sessions - but I would prefer to just hang it off my desktop if possible.

Working a full time job while working on a FOSS project

For those of you who work on FOSS projects and work a full time job (especially if you have one tech), how do you do it?

I have been working on a project for the past year and I was hoping to have it done by now, but I just can't muster the motivation to sit down and do coding/troubleshooting/documentation after dealing with people and technological gore all day.

I can sometimes muster the energy to get things done on weekends but even then I just want to relax.

Do I just need more discipline? Do I need an extra set of hands considering I am the only one working on the project? Any words of wisdom from people experienced with this?


For context, my day job is basically a team lead for a Service Desk where I have to do some advanced troubleshooting and a little bit of coding with Powershell.

The project I am working on is called LogicalArdour, which is supposed to give Ardour similar functionality to GarageBand out of the box.

Why are UNIX-like systems recommended for computer science?

When I was studying computer science in uni, it was recommended that we use Linux or Mac and if we insisted on using Windows, we were encouraged to use WSL or a VM. The lab computers were also running Linux (dual booting but we were told to use the Linux one). Similar story at work. Devs use Mac or WSL.

Why is this? Are there any practical reasons for UNIX-like systems being preferrable for computer science?

Non root sandboxing solutions (like chromium / web browsers ) except for native linux applications ? (shouldn't require root even once)

I am on a non root device and I would like to get a sandboxing solution , there is mbox which I have tried but it doesn't work on some devices and its 11 years old with no updates and the name was already a big part of the mail ecosystem that seaching for it took me a long time and it doesn't work.


There is bubblewrap which uses linux namespaces but I am not sure why but I tried to run it on a non root server and it just didn't work / couldn't install flatpak.

There are other options like libriscv but that requires me riscv executable and even then no offense to libriscv , I really really love that tool ,but it seems that I would lose performance.

Docker / podman require one time root (generally speaking podman is better)

Apptainer doesn't require root but it also uses name spaces (I can be totally wrong , I usually am)

I just need a sandbox where the applications wouldn't know that they are in sandbox (something like docker in that sense) but I am not root in the first place.

I haven't dived into the deep ends of sandboxing in linux but I may be wrong , I usually am , but browser model seems to provide the greatest level of sandboxing , yet they require wasm which just loses performance (yes they are "near" native) but the point of wasm in my opinion is that it can work on web browsers , is cross platform / platform agnostic and is near native.

There was this pnacl project by google which I was really excited for , but its discontinued and its much more of a cross platform thing again.

Linux is so much faster for compiling projects and playing Minecraft

I was using Windows 11 and recently switched to Linux. I am a software developer for Minecraft related stuff.

I saw an improvement on git operations, specially patches and bash noscripts, in comparison to linux Git Bash, performance is x100 faster when applying patches (almost instant compared to Windows having a 1 second delay per patch)

Also, running Minecraft, as I use it for debugging and run multiple instances, is much faster on startup and gameplay in general. Probably because it uses native libraries in comparison to Windows. Same happens when you run local Minecraft servers.

If you are a developer, this are the main reasons to use Linux, also, everything related to software development is better integrated into the terminal.

What changes should be to made to Linux if we ignore the "don't break userspace" rule?

Sometimes, breaking changes are good. However, the Linux kernel has a hard rule of not allowing patches that would break userspace.

Personally, I think that processes starting with 'X' should not be treated differently, because it just seems silly to me.

"Challenging to justify the resources required for Windows-specific builds."

Mattermost is dropping its official Windows builds, saying the low level of Windows deployment compared to Linux doesn't justify the resources in maintaining them.

Since we usually hear the opposite from most software companies, please allow me a moment of Schadenfreude!

What are we using for an email client these days?

I have been using Linux in various flavors as servers for years, but have just switched to using it as a daily driver. It's been a few years since the last email discussion here and it might be time for another. Despite the sense that email's time as the best communication tool is over, I can't get away from it. And if I have to spend another week on my host's webmail garbage, I am going to cry.

Is it still just Thunderbird? Geary?
