Oh yeah, the 365 version is terrible. And post of the time, it could have been a Python Gradio interface or similar simple implementation without having to fight so much to make basic things work. Most of what I want Excel to do it just isn't efficient enough for; particularly with lets and lambdas, it's gotten quite powerful as a programming paradigm where you can visualize and manipulate your data spatially in a kind of Logo / NetLogo style way which is really interesting, but the second you reference a few thousand cells a few times even a solid CPU starts screaming.
I use Excel for a decent number of tasks and can do some magic with it, but only ever really for work where it's easier to share a weird Excel sheet than it is to pass around a Python script (which given I teach Python, isn't actually as often as most people experience).
Any good options recommended for self-hosting something similarly functional that doesn't take too much effort to get up, audit, maintain? Discovery isn't really important for me, so federated isn't really necessary, but a cool extra. I'd love to host something or contribute to hosting for my gaming groups, my class or multiple classes at my school, or otherwise. Voice, chat, screen share, camera, would all be great if possible, but range of options would be good. I'm still using Mumble for gaming...
Haven't tinkered much with Matrix nor do I know much about Revolt, but I'm curious before I look into it deeper if anyone in the community has experience hosting any communication platforms for small, invitational groups.
