Has anyone set up a Kubernetes cluster using several RPIs? How did it go? Got any recommendations for distributions, tools, etc.?

#202I'm very happy about that !
I needed to build a low power Nas with ZFS and the only board that could do the job (gigabit Ethernet, sata IO, powerful 64 bits processor, 4GB of ram) was the rockpro64. Sadly I discovered after receiving it that it can't run regular Linux distros out of the box. I had to download an image from some guy on GitHub. He seemed reasonably trustworthy since it was linked from the manufacturer's page but there's still a small chance that my Nas is part of some botnet now. It's something that can't happen with major manufacturer's like raspberry.

#203Depending on the purpose, for example if somebody just wants a compact home cloud, the Odroid HC2 could also - still - be considered: https://www.hardkernel.com/shop/odroid-hc2-home-cloud-two/ - Half the RAM but double the cores. I'm waiting for some benchmarks to see if the RPi4 is faster and by how much. - Also Gigabit Ethernet and it works great. My downloads are always at 108-111MB/s for the whole transfer. - Not…
The USB port on the Odroid HC2 is 2.0, but the SATA interface is connected to a USB3 but, as is the Gigabit Ethernet.
Furthermore, SATA and Ethernet are connected to individual USB3 busses, as opposed to earlier RPi designs where everything shared the same USB2 bus.
I haven't checked the RPi 4 specs yet, but i can imagine it's still the same layout, just a faster bus, which can be "just fine" - it should be plenty fast to saturate a Gigabit ethernet as well as the SSD/HDD IO required to do that.

> This stated intention and rpi.org's actions Please, never shorten or distort domain names... I went to rpi.org which turned out to be a spam trap.
It's just a standard squatted domain, I don't see any spam trap.
I didn't mean email spam. Yes, domain thing, whatever it's called.

#205> Full-throughput Gigabit Ethernet
> Two USB 3.0 and two USB 2.0 ports
Does it mean no more shared bus and full bandwidth for ethernet and USB ?
> We’ve moved from USB micro-B to USB-C for our power connector. This supports an extra 500mA of current, ensuring we have a full 1.2A for downstream USB devices, even under heavy CPU load.
For each USB port ? Also, does it mean USB-C is soon to be ubiquitous ?

#206Earlier quoted context omitted.
How are you a non-profit if you pay a salary to you employees and allow your suppliers to make a profit?. They act as a 'low profit' company, but they do make profits.
Do you realise that non-profit means that you just don't have leftover cash at the end of the year in your balance sheet? Non-profits pay their employees and their suppliers, their financial situation has absolutely nothing to do with what you are implying.
I think the gp’s point is that to a lot of entities (employees, suppliers) there is little difference between for profit and non profit. And if your nonprofit is passing profit along to a for profit ... you can see how the lines blur. Maybe a way to interpret the above comment is that the incentive structure for many people involved is not significantly impacted by the nonprofit status. And non profits can have money left over at the end of the year, they just don’t distribute it to shareholders.

#207bastards! just bought 2 pi 3 model B+ a couple weeks back (still in their box too) and now this... Welp... back to ordering a few of these! man, thats some upgrade!
and the 4gb ones are already sold out...

I'd love to see other interesting $35 SBCs with reasonable performance.
You might check out the NanoPi Fire3, which I think came out in early 2018: https://www.friendlyarm.com/index.php?route=product/product&... Has an eight -core 1.4GHz CPU, and is otherwise mostly comparable to the new Pi: 1G RAM, 1Gb ethernet. Has an SD card slot and no built-in storage.
It's interesting, but it's an 8-way in-order part.
Shipping from them used to be horrendously expensive, but I'm happy to notice that changed. Thank you.

The RPi4 doesn't have sata.

#210>Are you still using VideoCore? >Yes. VideoCore 3D is the only publicly documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less. This stated intention and rpi.org's actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1] Secondly, why was rpi.org caught adding DRM chip…
1) They make a low cost computer where they've put significant work into making it more open software wise. Their revenue stream is through the sale of their hardware, why do they need to allow people to make clones? 2) Maybe it's to do with the terms in which they get the camera module? I don't know but I don't see them selling the camera as interoperable. Your comment just seems to exemplify the phrase: "No good de…
They've specifically said that the camera module DRM chip is there because they make money from selling the camera modules and they don't want third-party cloners undercutting their pricing and eating into their profits, as happened with the non-DRMed version one of the camera module. Thing is, the third-party camera modules aren't just much cheaper, they're also offered in a whole bunch of useful variants that aren't offered officially. So in order to ensure their continued profits, they're using DRM to actively make their platform less useful.
