Ooh exciting, I've wanted to find someone with your knowledge! I couldn't find a good answer when I was researching this a while back.
How powerful of a laser would I need to cut 18mm ply at a workable speed? Would I need crazy cooling setups? And what size steel or aluminium could I cut with that?
This would be a home DIY setup, but on the 'serious business' side of DIY.
Have a look at the Bananapi options, especially the R3. (Or the R2, it's a bit more mature)
It's a very capable single board computer with onboard managed switch, including SFP cages. If you want, you can buy antennas and utilise the wifi 6, or get a dedicated access point.
PFsense, openwrt, et al all have images. I think some people also run the mikrotik OS on it. It's powerful enough to run as a hypervisor so you can chop and change between all of these if you want.
It gets bonus points for accepting 5G modems for failover.
There's a lot more to it than that, but yes. At least in my world, RAID isn't really used for ingest, it's just not fast enough- A single camera at 4k will bring a gigabit network to its knees. IP networking is making it's way into the events space, but it's not straightforward, and generally isn't used for critical recording or archival, just for pushing content to screens. For recording it is usually done in camera, and this is directly piped over dedicated cabling to back of house where a recording station is set up. This cabling will either be SMPTE or SDI.
The most data I've recorded for a live event was on a show for a Tech Company You've Heard Of.
We had 8 cameras in the main room. This room ran for most of the day, can't recall how long but let's call it 8 hours, allowing time for lunch and turnarounds and such. This show ran for three days. We kept to good practice, and had a main and backup recording of each camera feed.
They wanted ProRes 444 HQ, I managed to convince them that 422 would be sufficient. Even so, at 4k, that's about half a terabyte per hour.
We could only get 2 terabyte SSDs in the quantity needed in time.
So that's 2 recordings of 8 cameras at half a terabyte an hour, giving 8 terabytes per hour, for 8 hours, giving 64 terabytes a day, for three days, giving just under 200 terabytes for the main room alone.
Do you know how tall a stack of a hundred SSDs is? I do...
I think about this in my workplace. I'm not on the IT side of things, but I do have more of an interest than most. And wow, it seems a mess.
I think the problem lies with all these nifty solutions being implemented, and then suddenly it's someone's job to tie them all together, which they get halfway through doing before they are called off to do some other task... There doesn't seem to be an overall architecture, or a coherent model of how information should flow around the business. I'm guessing you come across this a lot? How does that get solved?
Without knowing the setup, it's all guesswork- But if I had to guess, the program the robot ran through would be a series of movements that results in a box that is this size and this shape in this position being moved perfectly well to this particular spot.
Humans are not that size, that shape, or in that position.
I've not worked industrial in Asia, but where I have worked there has been stringent protocols around locking out machinery that has the potential to kill. For someone to enter a hazardous area, they have to remove any potential source of energy (eg, disconnecting power to motors, draining hydraulic pressure, lowering suspended loads, etc) and use a lock that only they have access to to prevent that energy returning. I'm guessing that this incident either did not have that procedure in place, or it was in place but not followed correctly.
I think the key here is integrating loading into the gameplay. The old Metroid trick of having the player traverse a basic hallway while the game loads the next area in the background is a good, if basic, example.
It's not so much about the audience perspective as it is the layout of the building. Just like backstage is the area behind the stage, other areas like behind the bar, or the storage areas, green rooms, offices, tech rooms, weird tunnels full of mysterious cables, etc are all collectively 'back of house'.
Like when you go to a big box store and they see if they've got something 'out the back', the back of house areas are those generally not seen by the public. The term front of house likely evolved as the opposite of this.
