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.

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. :(

- ZFS: Some copied files are still corrupted (chunks replaced by zeros)

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.

Using ZFS on single disks, combining them with mergerfs, and paritizing them with Snapraid

Why does primarycache=metadata reduce my un-cached read speeds?

Release Radar • March 2024 Edition
Having been featured in our February 2023, and January 2024 Release Radars, Moby is the original Linux Container runtime. This new version adds a bunch of changes to the Docker CLI and Moby itself with additional features. There's bug fixes and enhancements, with the main thing for users to be on the look out for containers that were created using Docker Engine 25.0.0. These containers might have duplicate MAC addresses, and thus must be recreated. The same goes for those containers created with Moby 25.0+ and with user defined MAC addresses. Read up on all these changes in the release notes.

Choosing a Name for Your Computer
Formlabs does this as well for their 3d printers, my earliest encounter of this was when Docker started getting popular: https://github.com/moby/moby/blob/master/pkg/namesgenerator/...
- Docker Inc. refuses to patch HIGH vulnerabilities in Docker

Do not install Docker Desktop on GNU/Linux systems
Try to use moby instead since that is the engine in Docker.

Exploring Podman: A More Secure Docker Alternative
> Podman is designed to help with this by providing stronger default security settings compared to Docker. Features like rootless containers, user namespaces, and seccomp profiles, while available in Docker, aren't enabled by default and often require extra setup.
Seccomp has been enabled by default since 2015: https://github.com/moby/moby/pull/18780
It is true that Rootless isn't enabled by default but its "extra setup" can be done with a single command (`dockerd-rootless-setuptool.sh install`)
- Moby: Block io_uring_* syscalls in default profile
- Io_uring will be blocked by default on Docker

OpenZFS 2.2: Block Cloning, Linux Containers, BLAKE3
Perhaps.
Thing is, https://github.com/moby/moby/blob/670bc0a46c4ca03b75f1e72f73... is using https://github.com/mistifyio/go-zfs which features code like `out, err := zfsOutput("get", "-H", key, d.Name)` (Source: https://github.com/mistifyio/go-zfs/blob/master/zfs.go#L315) to get a single zfs property.
Somebody chose to use a library as abstraction that looks good but is implemented as a MVP (nothing wrong with that). "In the future, we hope to work directly with libzfs" should have raised an alarm somewhere, though.
