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.

Ubuntu 24.04 LTS is so buggy you can't install the OS [video]
Be careful if you use ZFS-on-root, make sure not to snapshot bpool or it will brick your system and require a complete reinstall.

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.

ZFS 2.2.0 (RC): Block Cloning merged
> Systems are set up to automatically make snapshots
I do that with sqlite to keep a selection of snapshots from the last hours, days etc.

TIMESHIFT - Terminal command to automate deletion and creation of snapshots
I don't know about timeshift, but if you want to make snapshots on a 6 minute timer and keep the 10 most recent zfs snapshots for each of 10 month, day, hour check: https://github.com/csdvrx/zfs-autosnapshot

Been away from Linux for many years
if you're using zfs, try my zfs-autosnapshot: you get automatic snapshots every 6 minutes, converted in bookmarks then removed when it'd take too much disk space https://github.com/csdvrx/zfs-autosnapshot

Imagine You're a Goofball: Dynamic Preventative ZFS Snapshots
You need different rolling periods, each embedded into the other (ex: last 5 hours + last 5 days + last 5 weeks + ...) : check https://github.com/csdvrx/zfs-autosnapshot which has a tweakable logic, and brings in budgeted free-space to prune if required based on the least useful also using the most space.

OpenBSD Minimalist Desktop
ZFS
Since they are all taking from the available space of the pool, you can have as many partitions as you need, which is very practical for snapshots and diffs
Look at the set of partitions I recommend on https://github.com/csdvrx/zfs-autosnapshot:
zfs create -o mountpoint=/ nvme/7275

How to have 2 distributions share datasets with snaptops/clone/promote?
My own snapshotter (https://github.com/csdvrx/zfs-autosnapshot) works on a clock, and recursively: rolling back to 20210306231557 would roll back all the datasets (/usr /var /etc ...)
