In which case, just use Wifi :)
@ascherbaum having built some high density RPI cluster servers.
I'd go with CM4s over stock RPIs.
I will say, cabling is very easy to underestimate.
Even with on PCB switches, and in chassis switches, getting 96 nodes into 2U is a struggle. Especially if you want decent storage too.
Would be hard to use SPI like that, whilst its a multidrop bus, you need peripheral select lines to manage bus access.
Plus gate capacitance, trace length and slew rate come into play to limit things in practice.
Would be much better off going with CAN or RS485, except none of that would get close to the bandwidth of Ethernet, especially for the cost point.

@nixCraft Technically, I run my apps as containers on VMs on bare metal, so kind of all 3.

I've missed the CFP of @postgresuk because I thought I couldn't travel but it turns out I can go to London and come back in a single day by train. Same with Amsterdam. So I've just submitted a talk proposal for the brand new @pgdaylowlands 🐘🤞🏻

I see nightmare stories of bosses getting upset when employees take PTO for important life events. I was at my desk at a previous job when I got a call that a family member had become suddenly ill. My boss all but shoved me out the door: "Go be with your family. Now. Leave. Take care of this and don't come back until you're ready. We'll cover everything here."
I couldn't overstate the effect this had on my loyalty to that boss and company.

I had a talk about "performance cliffs" in #PostgreSQL (and cost-based optimizers in general) at #posetteconf yesterday. I think it went quite well, and the recording is now online, so maybe take a look. 😉
POSETTE is now over, such a great event it was too.
But fear not, if you missed the livestreams all the talks are on Youtube.
Checkout my talk on Even JSONB In PostgreSQL Needs Schemas!

Voting #ukpol?
If you're in the #UK, please ensure you're registered to #vote, and use it. I know it can feel like it doesn't make a difference, but governments don't care about people who don't vote.
For example:
Young people don't tend to vote. So student grants were dropped in favour of loans, and now we have tuition fees.
Old people do tend to vote, so we got triple-locked pensions.
