É normal ter instabilidade após um êxodo. Calma, gente. É nossa tarefa agora criar um comunidade digna de voltar sempre!

I'm sad to hear you did not feel like a good explanation of the fediverse was given. Is there something you'd still want to know? I'm no expert but I've been here for a while, so I might be able to help or at least guide you!

Feel free to ask! And if you don't feel like commenting on here, feel free to DM me with questions too.

Glad to have you around here!

Thanks! I can't wait to finish the campaign to play the community made content! I took a quick look and saw a lot, LOT of content! Makes me feel nostalgic for HL2!

The only real "problem" would be the lack of certifications, which are quite hard to get.

Real Time Operating Systems (RTOS) are normally used for these tasks, but, AFAIK there are already projects using linux with patches to make it run a RTOS kernel.

In my opinion, I think it all depends on what part of the plane it is running. If it is a core sensor, providing real time data, it makes a lot of sense to use a RTOS. It needs to prove it can run its tasks on time, and the scheduler needs to be understandable. There's also a lot of overhead with running a full OS with processes, which don't make sense for a sensor which only function is to provide data over a CAN/LIN bus.

But, for other things, like dashboard visualizations, music for the aircraft, entertainment, and those non-critical-realtime needs, then it makes a lot of sense to run linux. After all, you'd get access to a lot of already built software and a working dev environment.

And don't get me wrong, this is clearly BS from boeing to keep selling their closed source software. There are already open source RTOS systems, like FreeRTOS. I do not mean to keep those real time systems closed, but to use a full OS where it makes sense and a RTOS where that makes more sense. Both open source!

I am currently playing Half Life Alyx with a Quest 2 and a cable to my PC. Incredible game, totally recommended. If you want to feel what Virtual Reality (VR) is about, please play that game.

A bit off topic, but isn't it great? Shows us decentralization is working!

What about cryptomator for encryption and syncthing for syncing files to another place? Not exactly a backup per se but it works reliably.

Is this how a recession feels?

Thankfully it still works!
