That only partly helps with cheating. Client side cheat software still has access to the internal game state and can modify rendering (so you see in the dark for example) or input (point the gun at any visible opponent). If you only remotel

That sounds pointless. If you have real crypto, tossing the key (in a way that it cannot be recovered) is absolutely enough.

I'm not entirely sure I understand what you're asking for, but it sounds like zsync ( http://zsync.moria.org.uk/ ) is what you're looking for.

Is it normal for these internal system to not implement any kind of access control? From the post it seems every reader can access every stream?

I don't think there's any reason to upgrade unless some of your dependencies require a higher version and backporting is more expensive that porting over all your existing code. Since it sounds like you expose libraries with your

It's the language used in my digital signage service for the Raspberry Pi (see https://info-beamer.com & https://info-beamer.com/doc/info-beamer ). The main reason to choose Lua back when I started

Ah. Yeah applying resource limitations outside of memory usage is always a bit awkward. The only really supported way to my knowledge is to externally set a hook and trigger an error when called: https://github.com/lua/

Kind of. Originally, info-beamer for the Pi started as a standalone binary intended to run on Raspbian. This product (info-beamer pi) is still available and has also been updated to support HEVC playback. See here: https://info-b

To be fair, these kind of low level stuff is usually handled by only a handful people, so investing a lot of time in proper documentation might be a lot of work for something useful by few users. The same is also true for DRM and in general

That's correct. The naming was due to it being initial built to show information (=info) on a projector (=beamer) at a German hacker conference to inform visitors about talks, tweets and more. You can actually see the very first public

In hindsight I should probably named everything differently, but I didn't expect the software to turn into a company at some point when I initially started it over 8 years ago for a hacker conference (see https://github.com&

Hey. It took around two months of digging into (sometimes undocumented) APIs to get this one working on the Pi4. The player software ("info-beamer pi") can now use DRM/dispmanx/MMAL to place videos, either decoded using

Not sure to be honest. From the documentation: "Writing "FROZEN" to the state file will freeze all tasks in the cgroup". Even if not, it should still be sufficient once all tasks are frozen: If you then send SIGKILL to a

That's definitely the correct way to do this today. But even then `kill -9 $(< /sys/fs/cgroup/systemd/tasks)` is not enough if your goal is to reliably kill all processes because that's not atomic. Inst

If you can live with a pure software version for the Pi, have a look at https://info-beamer.com/pkg/8474 . If easy to install using the OS we build and you can update it remotely through an API or of course on-device.

Their USB charger costs 7€. From my experience: Just buy their charger and you'll have no problem. I've seen so many attempts at powering the Pi with alternative sources that suck and cause problems. 7€ is worth avoiding that.
