How Long Have You Been Running With Open Sensors?

I was looking at the different possible solutions for like the beam, right? And then I definitely stumbled across those two different things. So why don't it give us a bit of a gist, like a history then, like how you ended up doing what we're doing? Yeah, so I got it. But I mean, it just said, okay, you've been running for 19 years now with open sensors for like how long, I mean to how long that? Because I actually still remember when open sensors and open tracing were two different thing. Like I did, I don't even show what we exactly ended up using.
