Ask HN: Does anyone care about OpenPOWER?
I care! And I know a lot of people who care, but we are still a niche sized group. I care mainly because of Raptor Computing Systems offerings, which I think are the main (only?) OpenPOWER systems available. I use a Blackbird, and I'm happy with it.
From my own point of view, I'm willing to spend a $$$$ premium on hardware where I can have assurances that from the time I boot it, only code I authorize to run is run. Where every part of the system has code that, at least in principle, I or someone else could audit and fix. People have valuable IP stored on computers and it's worth much more than a few thousand dollars.
If you just look at price to performance, you are missing the point. Also, the price is not out of line with other niche desktops such as Apple's or System76.
There's not a lot of competition in this niche. The previous system that was useful was a ASUS KGPE-D16 motherboard, which could be librebooted (https://libreboot.org/docs/hardware/kgpe-d16.html) I expect something new to come along in this space every 5-10 years.
For my purposes, I haven't fought with the software ecosystem, and was able to compile the very few packages that weren't already precompiled.
Here are some developments I think are worth noting:
* There is a libre driver for the onboard NIC. (https://github.com/meklort/bcm5719-fw) This seems to be the only project that cares about blobs in every part of the board.
* Dasharo https://www.dasharo.com/ providing alternative boot firmware.
* Artic Tern, (https://www.raptorcs.com/content/AT1PC2/intro.html) which is objectively still mostly a development platform (that if you're skilled you can get to work) provides a completely libre boot environment and the possibility of controlling other peripherals using only auditable code.
A few things have not yet made it onto the board:
* Flexver (https://www.raptorengineering.com/TALOS/documentation/flexve...) which would allow for verifying and auditing hardware, firmware and the boot process isn't commercially available yet.
* Ultravisor state enabling more secure VMs is still awaiting implementation AFAIK. (https://wiki.raptorcs.com/wiki/Power_ISA/Privilege_States#Ul...)
* I'm not aware of a lot of hardware that would take advantage of IBM CAPI 2.0 IO accelleration. Perhaps someone has some information on this.
* I'm not sure what the status of transactional memory is, but I'm not aware of it being used in software. Perhaps someone can enlighten me on this.
These would be nice to have, and I hope to have them in the future.
The bottom line is that this is the only hardware currently in production that is going in the direction promised by the personal computing revolution back in the 1970s and 80s and is still capable of handling most people's current general computing needs. I write this hoping that other people like me who are reading this understand the importance of keeping hardware like this alive.

The FSF’s relationship with firmware is harmful to free software users
The Talos II is blob-free. At launch, proprietary binary-only firmware was required for the network interface, but Raptor Computing Systems offered a bounty to reverse engineer and do a Free Software re-implementation of the firmware, and that effort succeeded and the bounty was paid. See:

Reverse Engineered GTA3 & Vice City got DMCA-d on Github
A clean-room RE requires one party to determine the behaviour of the original product, and write a spec for it. Then a second, completely different party must build the reimplementation using only that spec. They can't communicate with the first party through any means other than that spec. For a pretty clear example of this practice at work in open source, see the work to reverse-engineer and then reimpliment an open-source driver for the Broadcom BCM5719 NIC.

Has anyone used a HPE FlexFabric 533FLR-T Dual Port 10GbE card in a regular PC?

Bought myself a EqualLogic SAN for $1 only to immediately realize it's useless to me
Sometimes the connectors are proprietary but in the end it's just rewired PCIe. It's done on purpose to lock you into their platform. For example FlexibleLOM claims to be all custom, but it's just PCIe with a different wiring. Some figured out how to rewire it back to standard PCIe: https://github.com/TobleMiner/HPE-FlexibleLOM-adapter and with this you can even use FlexibleLOM 40Gbit network cards in your desktop.

old 10GbE SFP+ cards vs mellanox CX3/Intel based solutions?
These FlexibleLOM-cards requires adapter like https://github.com/KCORES/KCORES-FlexibleLOM-Adapter / https://github.com/TobleMiner/HPE-FlexibleLOM-adapter

Does HP 331FLR NIC really work in pfSense / Proxmox / TrueNAS Core or not?
And yeah, I spotted PCI-E adapters, that's why I was interested in Flex LOM card in the first place, I am on Supermicro myself. Adapters are actually open source hardware: https://github.com/TobleMiner/HPE-FlexibleLOM-adapter https://github.com/KCORES/KCORES-FlexibleLOM-Adapter

will HP 366FLR work in PCIE slot?
Check out this project. For 1G cards it's probably not worth it but for 10G or greater, it might make sense.

Hardkernel adds 4x 2.5Gbps to H2
> Right now the cheapest options are to get a 10Gb PCIe card from Newegg or similar, which'll run you about $200 where I am, and that's just a PCIe extension card.
If you want to go _very_ cheap and dirty you can get some FlexibleLOM/PCIe adapters [1] and get some HP FlexibleLOM NICs [2]. 2x 10G NIC for around ~$15, including the adapter.
