Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The Orange Pi 5
Generally yes. M.2 wifi cards are just PCI-E (except for Intel CNVio). Jeff Geerling tried a bunch of different PCI-E cards with the Raspberry Pi 4 Compute Module which does expose the PCI-E interface: https://pipci.jeffgeerling.com/

AMD's 22-year-old GPUs still getting driver updates thanks to the FOSS community
We're also trying to preserve the utility of older cards by getting at least portions of the drivers working on alternate platforms (like arm64), so they can be repurposed for Plex/Jellyfin transcoding, retro gaming, GPU compute, etc.: https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...

Double Standards
The current answer is maybe: https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...
The PCIe implementation on the 5 is supposedly more complete/less broken than on the CM4, but so far the only person crazy/inspired enough to test hasn't gotten back to this card with their Pi 5 setup.

Still no love for WPA3 on the Raspberry Pi 5
Just a note that if you're _serious_ about WiFi on the Raspberry Pi... you should use an external WiFi adapter—either PCIe or USB.
With the Compute Module 4, I've successfully tested a variety of adapters [1], from WiFi 6E to older mini PCIe and M.2 cards. There's even a board made for the purpose of multi-WiFi testing, the Seaberry [2].
The Raspberry Pi 5 works with all the PCIe WiFi chips I've tested (haven't had time to summarize testing on pipci database site yet, including a mt7921u-based WiFi 6E USB adapter (haven't written that up, but check out [3]).

Raspberry Pi 5 drops codec hardware acceleration except for HEVC decode
https://pipci.jeffgeerling.com honestly I'd get a home server and run HA through docker, it's gotten me into home servers.

Graphics card integration
The simplest access you can get would be by using a CM board (as that has PCI Express available on its connectors) but driver issues galore exist. AMD have been more open the the "greenies" but the closest result I have seen is documented by Jeff Geerling

Bought 2 Raspberry Pi 4 accidentally!
Are you familiar with a YouTuber named Jeff Geerling? He does some pretty far out stuff with pi’s like connecting video cards to them, etc. here’s a videoabout stuff you could do, I haven’t watched it myself. He’s got this website that has a list of accessories he’s tried with the pi. While I was looking for his channel I saw a ton of videos on YouTube for stuff to do with the pi. Curious to see what you end up doing… I guess I’m kinda hoping you do something that utilizes the full potential of the 4 😁

Radxa's SATA HAT makes compact Pi 5 NAS
> The only non-junk PCIe3 option that's even advertised here recently is the overpriced WD Red SN700.
Those WD drives seem to have some real issues, at least with ZFS and btrfs. :(

DiskClick: Ever wanted to hear Old Hard drive sounds
IMO the "next fs" is just zfs. They somewhat recently merged RAIDZ expansion feature https://github.com/openzfs/zfs/pull/12225 and make regular improvements. If no file system has what you need today, zfs will probably be the first one to have it "tomorrow," imo.

A data corruption bug in OpenZFS?
https://github.com/openzfs/zfs/issues/15526#issuecomment-181...
> zpool get all tank | grep bclone
> kc3000 bcloneused 442M
> kc3000 bclonesaved 1.42G
> kc3000 bcloneratio 4.30x
> My understanding is this: If the result is 0 for both bcloneused and bclonesaved then it's safe to say that you don't have silent corruption.

Ask HN: What's your "it's not stupid if it works" story?
A couple years ago, I had an idea for convincing a filesystem to go faster using 2 compression steps instead of one. I couldn't see why it wouldn't work, and I also couldn't convince myself it should.
It seems to have worked out. [1]

ZFS Profiling on Arch Linux
https://github.com/openzfs/zfs/issues/7631
This is a long-standing issue with zvols which affects overall system stability, and has no real solution as of yet.
