Sure, if I want to run something heavy I’ll upgrade, but if it fits my compute power needs would you still have a problem with it?

Why "upgrade" when you could have paid less for a better PC? This is my issue with RPi. Usually upgrades are more expensive.

Fair enough. So your basic point is that I should just buy more computer than I need in case I want to run something else because it’ll be easier to buy too much than upgrade and migrate.

Yes basically. I started with RPi too, everyone on twitter had them and a cool case. But it wasn't even enough power to run a mid level lightning node that balanced channels once every 5 minutes.

Speaking from experience here! I'm mad that bitcoiners all recommended it and it's a piece of shit 🧑

Later this month I have to move a cluster I built from 36 tower PC’s and 100’s of meters of infiniband.

It’s amazing what you can do with a pallet of refurb. πŸ˜‰

Infiniband sounds like Cisco

Mellanox

The cables cost more than the PC’s.

I needed to build a memory fabric and lots of sockets+infiniband was the most scalable way to do it.

Mellanox, crazy expensive cables, infiniband, so Cisco

Actually technically Mellanox was acquired by NVIDIA..

ever since nvidia acquired them

I seem to recall it was pretty expensive tech even before NVIDIA acquired them. I’m sure NVIDIA cranked up the price.

Yeah, cables are $1000s…

Interesting, I have ~100x of these lying around.

100x Mellanox cables? Basically used to connect and train supercomputers? Yeah, pretty sure they are holding value better than the dollar.

Yep, I have probably 500m - 1km of this stuff.

80 GB/s plus all the network cards and two switches.

When did they get that expensive? Bought some for maybe 200 a few years ago

I’ve seen them for $500-$1000 new from Mellanox

Same

I just remember we had to expense like 10 and it was many thousands of dollars, had to get special approvals..

Okay my cables were 100Gb/s, no splitter and definitely not 4m

Still, that’s a ridiculous price for a cable.

Just like the $65k switch

Good to hear your perspective. I think RPi gained traction because it was easy to setup with Umbrel with little knowledge/skills. For me, I have no idea what to do with Ubuntu or Debian on a small PC - drivers etc
