Well everyone, it's the first week in July, and #Reddit CEO Steve Huffman is still a lying asshat who treats Redditors as voiceless resources to exploit. So, as promised, I'm off Reddit and out of r/zfs for good.

The good news is, Practical ZFS is up and running as a replacement, with more than 100 registrations in its first day online and more continuing to come in. I hope to see you there soon!

Community Members and Community Supporters wanted!

I've set up a new home for OpenZFS community news, discussion, and education at https://discourse.practicalzfs.com/ and although it's still new and ugly, it's ready for folks to start kicking the tires.

Listening to myself talk about SSH keys, as I "proof-listened" the most recent @25admins episode, I tried to hear it with newer ears, and it reminded me how long it took to grok public/private key infrastructure.

It occurs to me that we missed a MUCH better naming schema. Your private key is just a key. Keys are private by nature. Your public key is a LOCK. Locks are public by nature.

In that metaphor, you install your lock on a server so that your key will unlock it.

Adventures in a long-untended facility network with no administrator-level access continue. Progress is made! Terrible over-bent optic patch cables are replaced! Network latency is down... WAY down!

If you're interested in the details--or would just enjoy a good sea story--I wrote them up here: https://jrs-s.net/2023/09/30/adventures-in-network-repair/

Confession: I still browse r/zfs on Reddit every few days. I try never to respond there anymore, because principles are principles, but it's HARD seeing people's questions go either unanswered or--worse, and all too frequently--very, very badly mis-answered.

It feels like extremely bad form to continue to advertise Practical ZFS there on Reddit, but please... if you have ZFS questions, go to https://discourse.practicalzfs.com/ for answers. Reddit is a festering corpse.

I'm probably never going to write the actual article I'd originally intended these charts for. But if you want to see the difference between latencies between #OpenZFS and #btrfs on an eight-drive system that's creating and replicating automated snapshots regularly, here ya go.

We're looking at fio random access, limited to (simultaneous) 8MiB/sec read and 23.0MiB/sec write. The system has eight 12TB Ironwolf rust drives, in four ZFS mirrors vs one eight-wide btrfs-raid1.

r/place is going nicely this year.😂

There's certainly more than one reason I strongly prefer free and open source operating systems and other software. But this ONE would frankly be enough, all on its own.

This is the face of enshittification.

The really "fun" thing about getting one of your sites false-positive detected as a malware site is that pretty much all of the engines use EACH OTHER as data points, so once one of them flags you, all the others immediately follow suit... but they generally DON'T follow one another in terms of REMOVING false positive detection results.

So if eg Kaspersky sneezes, you have ten or more badly documented and completely different removal request procedures to follow.

It's a very sad sign for society at large when a network with the history and prominence of NBC decides that running grift ads via Taboola for a few pennies is a good idea.

(And I PROMISE there's nowhere you can stab your phone with a toothpick to make it block ads.)

I bought a 200W charger last week which puts my Galaxy tablet in "Super Fast Charging" mode when plugged in... which, I discovered, has a different sound effect.

"Super Fast" charging mode has essentially the same sound effect as regular charging, but with a ton of lilting reverb added. It makes the tablet sound excited to get plugged in, which is a little weird.

Anthropomorphization, away!

Ars Technica's Ron Amadeo reports in depth on the bug we brought up in this week's @25admins : people with multiple user profiles on Android 14 devices are being locked out of their main profile.

Y'all, I don't know what we said to give everyone the impression that Allan and I didn't know that hard drives (like floppies) originally had larger platters, but I promise, we knew.

The first hard drives I used were Winchester style 5MiB drives the size of small office copiers, attached to TRS-80 Model II business machines.

The heads rode on air cushions, and if somebody bumped the table, the head would plow into the platter. That's where "drive crash" comes from.

You can give a Microsoft person a main ballroom to speak in, and they can give an excellent talk on #WSL... But you can't get many of the Linux conference attendees to show up for it. ☹️

So I just restarted my machine, and um excuse me whatteth the absolute fuck?!

I don't think I realized how easy it was to block entire Masto instances as a user--not just as an instance admin--until today. It's literally two clicks and done.

So there's DEFINITELY no need for anyone to lose their mind over commercial ventures offering Fediverse integration. If #Bluesky or #Threads or whatever shows up in your timeline and you don't like it, just find any post from any user on that platform, click the hamburger menu, and click block domain: DONE.

Hey everybody! PSA:

Both 2.5admins.com and practicalzfs.com are currently offline, due to their entire datacenter also being offline, possibly due to extreme inclement weather.

We have full backups, and are monitoring the situation at the datacenter to determine if/when we give up on them and spin up a new host elsewhere.

I think AI music generation has reached a similar level as AI image generation. Behold, "sad girl on piano sings the MIT license" as generated by suno dot ai:

Good(ish) news, everyone!

I got off my ass and set up a vhost on a different webserver for the (bare) practicalzfs.com. It just redirects to discourse.practicalzfs.com for the moment, but that's enough to give it its own SSL certificate so nobody who types in the barename gets a cert mismatch error.

Baby steps? :)

#OpenZFS #replication is an incredibly powerful tool in every sysadmins' tool belt. Join us on Wednesday, September 13th as Klara co-founder Allan Jude and ZFS Expert Jim Salter examine how to reliably replicate data using ZFS send and receive.

I love BSD in any flavor, but weird to see someone say zfs is developed Linux first. Is this really the case? #bsd #zfs
