Hi! I'm Jim Salter, aka mercenary_sysadmin, aka "the biggest ZFS stan on the planet."

I am not Jim Salter, the Associated Press reporter based in Missouri. That's a different guy, and he hides from the Internet.

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 and 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.

@ojs no pardon necessary, thank you for asking!

This is a range of fio latency results on a long-running test. What you're looking at is a line of individual data points running from best result (lowest latency) on the left, at x=0%, to worst result (highest latency) on the right, at x=100%.

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.

@jens @25admins does it really "work" for either, though?

You might as well call it private foo / public foo. I doubt that would confuse anyone any more than "key" does.

It's been griping me for YEARS that can only give a progress bar for the CURRENT replication task, not for the entire job (when it involves multiple datasets).

The problem is that it relies on an external program for the progress meter, which means you can only meter the one task at a time.

That's gonna change real soon. We gonna have simultaneous progress bars for the current task, and for the ENTIRE set of tasks:

Oh the Canadian clown is an idiot. Please tell me more. Your ideas are intriguing to me, and I wish to subscribe to your newsletter.

@JoeRess what did Allan do this time? 🙃

@JoeRess yes, but there's really no shortage of the former. You might as well say "the British clown."

I think we need some laws with real teeth in them about training AI models to fraudulently deceive humans into believing they are also human.

I asked one to speak to its supervisor today, and it claimed "there is a real live human here, so I am disconnecting."

Thing is, I never accused it of being a robot... but it's been trained to lie about NOT being one. Strongly. Explicitly.

AFAICT that's technically legal (in the USA). It shouldn't be.

How often do you buy a new primary computing device?

jimsalter,
@jimsalter@fosstodon.org avatar

@JoeRess my main downstairs workstation is an R7-3700X that replaced an i7-2600. So that's... eight years, and roughly quadruple the (CPU) performance.

Pretty sure that's been my rough MO ever since I gave up on the "PC of Theseus" model 25-ish years ago.

Auto brightness?

jimsalter,
@jimsalter@fosstodon.org avatar

@JoeRess depends how stupid the algorithm and how smart the sensor is, really. I'm usually an auto-brightness guy, but I gave up in disgust with my Tesla's screen; it stays SUPER dim forever when I'm backing out of the carport if I let it have control.

How do you explain the difference between it's and its to your friends? The polite thing is to just humour them and not correct them, right?

jimsalter,
@jimsalter@fosstodon.org avatar

@JoeRess "it's" is a contraction of "it is," and means exactly the same thing as "it is."

"Its" is a self-contained word which means "belonging to it" and is not a contraction of anything else.

Is there a way to make an Android phone (stock Pixel 7) open all Mastodon links in the official Masoton app? It seems like impossible to me because there are so many different servers but maybe I'm missing something.

jimsalter,
@jimsalter@fosstodon.org avatar

@JoeRess there's an official app? I thought "official" was just doing the "install as app" shortcut trick with Chrome.

If you want to convince an "esteemed journalist" that your project deserves to fail horribly, and for said journalist to consider ways to help make it happen, talking about your "last follow-up" on your very first message is a great way to do it.

I will never understand why people tolerate this shit.

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.)

On the one hand it's annoying that @jimsalter confused AirTags with some Tiles when it comes to replacing their batteries on @25admins. But on the other, it's nice to know that people out there are listening and paying attention. I'll try to see the bright side of every email we get over the next week or so. 🤦‍♂️

jimsalter,
@jimsalter@fosstodon.org avatar

@JoeRess @25admins yes, Apple actually deserved kudos here. It's not just "old" Tiles; either--there are four Tile models available currently, and only one (Tile Pro) has a replaceable battery.

Replaceables remain rare when you venture into also-ran and knockoff brands of BT tracker.

Well done, Apple, and you can quote me on that.

@jimsalter Soooo about that Oracle response! :)

https://www.oracle.com/news/announcement/blog/keep-linux-open-and-free-2023-07-10/

I mean, this IS sattire right? They can't POSSIBLY be seriously trying to assert that Redhat is in the wrong for closing previously opened source?

bursts out in uncontrollable laughter

There are humans I care about working for both RedHat and Oracle, so I will not in fact wish those companies would simply burst into flame and vanish but... Wow :)

jimsalter,
@jimsalter@fosstodon.org avatar

@feoh issues with Oracle corporate aside, I was howling at the gigantic slap at the end:

"Finally, to IBM, here’s a big idea for you. You say that you don’t want to pay all those RHEL developers? Here’s how you can save money: just pull from us. Become a downstream distributor of Oracle Linux. We will happily take on the burden."

And, say this for Oracle: they've been excellent stewards of MySQL (against my personal expectations). Credit where credit's due.

@jimsalter@fosstodon.org avatar

@jgeorge @feoh the community folks there (the ones who work on MySQL for example) could say it with a straight face. Granted, they'd have to be looking in the opposite direction from the proprietary division, but...

jimsalter,
@jimsalter@fosstodon.org avatar

@feoh @jgeorge it's a little early to say that pipeline is closed. As long as new dev is done in Stream, the vast majority of the upstream contributions from red hat to the community at large will continue.

With that said... If this bullshit flies unchecked, it won't be long IMO before the same suits decide that they shouldn't bother "letting" the community see the source on the individual projects either, and put a massive set of brakes on a lot of the open development.
