I'd recommend getting a prusa kit for anyone interested in building stuff. The instructions are easy to follow and broken up nicely. IMO it's also fun to see the parts and a glimpse of the design you wouldn't see buying a complete printer.
IF I managed to scale what I'm doing then this is my plan. I've built a RepRap in the past so I do understand the inner workings, however if I scale up I'll by going with Prusa, so building the kit means that I'll be able to actually service them myself (and if that happens I'll be adding 2-3 a month to my farm).
Bambu are cheaper in Cap Ex but based on reliability they will likely have a similar TCO after a year. Also as a Chinese brand Bambu are risky. If we get tariffs or some kind of international situation then things could be problematic.
The study seems to contradict this: "When broken out by size, small cars have the highest fatal accident rate while midsize and full-size cars are both below average."
And later in the study, “When two small cars collide the forces are equalized and both vehicles tend to hold up well. But if a compact hatchback and a full-size pickup truck try to occupy the same space at the same time, the smaller car always loses.”
My life on AWS the last five or so years really would have been a lot simpler if every new generation of EC2 servers didn't have the exact same ratio of RAM to cores.
At this point the memory:vcpu ratio is the defining characteristic of main general purpose C/M/R series, I'd think it would be pretty disrupting to change that significantly anymore. And they got also the special extra-high memory X series available. I would say ec2 is pretty flexible in this regard, you have options for 2/4/8/16/32 gigabytes per vcpu. It's mostly problem if you need even less memory than what C series provide, or need some special features.
As products age they tend to use more memory. Add in space/time tradeoffs asking to use more. You either get stuck applying the brakes trying to keep the memory creep at bay, or you give in and jump to 2x the memory pool which will disappear too.
The old solution in on-prem was to populate machines with 2/3 to 3/4 of their max addressable memory and push back on the expensive upgrade as long as possible, or at least until memory prices came down for the most expensive modules. Then faster hard drives or new boxes are the next step.
