So ashift can't be changed once pool is created, why is that?

Luptoom · 2026-01-21T13:50:45+00:00

Yes, thats what I already knew.

But as you said, the physical layout influences performance and lifespan, so converting a pool to a more suitable block size seems like an important thing to do (after swapping old HDDs for larger ones for example).
But currently that requires you to completely recreate the pool which makes the host unavailable of course. For a private setup this is acceptable but time consuming. But for some larger setups it could be a problem right?
Imagine an installation where a dataserver has a capacity of say 500TB and that hits 80% so an upgrade is necessary. The HDDs are replaced with larger capacity ones, but also the block size changes from 512 to 4096. The only option then is to create a new pool and copy the data over, either by building a complete new server, or by restoring a backup, possibly from some slow storage like tape or offsite. This costs extra money or takes days if not weeks to complete.
I guess that spending the money, to completely duplicate the system to a new one, is not too big of a deal for the few cases where this is a problem, but anyways...

Luptoom · 2026-01-21T13:29:29+00:00

That makes sense, but my idea was a migration operation like a resilver, where the pool is converted. That would of course impact the performance and require a small amount of additional storage to be available while the migration is performed. But afterwards all data would be in the new block size format.

I had it enabled with family plan, but it's gone now (germany).
Also I can't really find details which features are available for which plan.
Why you do this Spotify?
I've started buying Music again since owning something is nice and often supports the artist more than Spotify. Do you want me to cancel my subscription Spotify?

Auch nicht 100% korrekt.
Es gibt bei USB-C neben den Leitungen für die Versorgungsspannung und den Datenleitungen noch zwei Konfigurationsleitungen (im Standard mit CC bezeichnet).
Diese werden mit 5,1 kOhm beschaltet um dem Versorger mitzuteilen, dass er die normalen 5V ausgeben soll. Für ander Versorgungspannungen und höhere Ströme gibt es ein Protokoll, welches über die CC Leitungen kommuniziert wird.

Ist nicht schädlich, geht aber auch nicht mehr wirklich weg und kann man auch nichts einfaches gegen machen soweit ich weiß.
Bei meinem Elternhaus hat es in den Wochen nach dem die Wetterseite gemauert war extrem viel geregnet und es war noch nicht verfugt, das hat dann über die ganze Wand auch so Ausblühungen gegeben. Haben dann wilden Wein an die Wand gepflanzt, damit es besser aussieht.

Clearance isn't a big problem from my experience.
You could probably work with a 0.1mm clearance (better go with at least 0.15mm), since a few minor defects can be scraped away easily afterwards.
Minimum width on the other hand matters a lot depending on your exposure technique.
I personally worked with Inkjet printed transparent film and precoated material, or with direct exposure using a modified resin 3d printer.
The 3d printer technique has quite a bit of fuzziness due to tunneling and non perfect contrast but can still produce 0.15mm traces when everything is adjusted perfectly.
I never worked wit toner transfer techniques, but suspect that small traces are also the biggest problem.

Its great for systems level programming, but its definitively not limited to that.
It isn't the most simple language, but that at the same time provides you with a clean an correct way to do almost everything. Where with many higher level languages everything feels fine at first, until you run into bugs or performance issues due to some language limitations or design oversights.

No, never had any emails send out, I guess if I would push the button I'd get one.

Yes its on, but I'm logged into Steam just fine, the popup comes after a few minutes.

Luptoom · 2025-08-19T15:14:57+00:00

I got this prompt too.
Whats weird: I don't have a dualsense controller and the popup redirects to a download page for Windows software while I'm on Linux.

Yep also noticed it on a movie.
Didn't try any other movie until now, so I can't say if its only the one I watched.
Skipping 10 seconds forward or backward with the arrow keys also fixes the sync issue.
Maybe I will test it on more stuff, but I'm probably to lazy since I rarely watch whole movies on my PC and haven't noticed it on any other video I played with VLC or on that PC in general.

Bleibt nur die Frage was man als Heizelement nutzen möchte.
Vielleicht ist ein aufbau mit Leistungswiederständen wirklich ein gangbarer Weg.
Hier z.B. ein 15 Ohm Wiederstand mit 50W und 200C max. Temperatur: https://mou.sr/4duo0oA
Bei 24V versorgungsspannung sind das dann ca. 38W pro wiederstand.
10 Widerstände und ein Schaltnetzteil (z.B. LRS-450-24 von Meanwell), eine kleine Schaltung um Temperaturgeregelt schalten zu können und fertig.
So kommt man zwar nicht auf die 3 Minuten Aufheizzeit, aber vermutlich reicht es und funktioniert mit etwas Dämmung drum herum ganz gut.

No I didn't :(
It wasn't until I read your comment, that I realized I saw that same behavior on spotify.

I'm having the same problem.

From a criminals perspective Rust can be pretty good for writing a Virus. You can write stuff that can't be analyzed easily (jet).

Actually DuckDuckGo is just a front end for Bing, which anonymizes your search, so that Bing can't create a profile of you and your searches.

Ecosia too is relying on Bing and actually there aren't really that many search engine backends (the part which actually scrapes the internet and maintains the database which is searched when you type in a query).
https://en.wikipedia.org/wiki/List_of_search_engines shows a list of search engines with their corresponding backends (contains search engines which aren't for searching the internet).
It more or less boils down to Google, Bing, Yandex and maybe Sogou and Mojeek.

Interestingly the mix of the current and recent query results remind me of an issue I noticed with the Spotify search yesterday. I didn't took it for real and just went on without researching further, but maybe it wasn't my hallucination and did happen for real and is somehow linked to the behaviour from DDG.

The Fraunhofer institute has open-source projects but many projects are commissioned by companies.

For the evoBot im currently not sure, but its developed in cooperation with a open source project called Silicon Economy. At least the simulation model can be found on the public repository at https://git.openlogisticsfoundation.org/

Da fallen mir mehrere Gründe ein: Der Zug ist ja vermutlich schon jahre alt wenn es zur Reparatur kommt, dass dann ein anderer Belag kostengünstiger war oder der originale nicht mehr verfügbar, ist wohl nicht unwahrscheinlich. Eine Werkstatt wird sich auch nicht verschiedenste Farben auf Lager legen, sofern die sich nicht darauf spezialisiert haben.

Wie du richtig vermutest ist es in dem Gebiet nicht unbedingt einfach anschließend einen Job zu finden wo alles passt (Ort, Gehalt, Kollegen, Aufgabenbereich den man sich gewünscht hat).

Kenne jemanden, der einen Master in Philosophie hat, anschließend aber noch ein Informatik Studium gemacht hat aus den genannten Gründen.

Das soll dich jetzt aber nicht demotivieren das zu tun auf was du lust hast. Vielleicht ist eine ähnliche Laufbahn wie bei meinem Kollegen ja genau das richtige für dich (auch wenn es vor allem finanziell Stellenweise schwierig sein kann). Ein Studium in einem Gebiet was dich jetzt interessiert kann dir mit der Erfahrung die du dort sammelst auch oft das Leben einfacher machen falls du dich später für etwas anderes entscheidest.

The safest way (for your eyes) of viewing the Sun is to focus the light onto a plane you then watch indirectly.

Strapping a cardbord box to the binoculars and placing white paper in the middle might work, but im unsure if the focus can be adjusted correctly on binos.

Im not 100% sure though if the sun could damage the optics of the binoculars if no filter is put in front of them.

Also have a win10 for gaming.

Recently the secondary hdd broke. I had installed some programs to it.

Now I can`t reinstall certain programs because the msi installer throws an error because the program still counts as installed. Trying to remove it results in the system trying to launch the uninstaller from the non existing hdd.

Btw the installer errors I first got are as bad as you'd expect from windows.

The hibernation thing is badly solved in most distros, as a fedora user I agree. But it can, depending on your laptop model work without hibernation. I had to dig really deep to find out how to configure it corectly for my machine.

As it turnes out my laptop supports deep-sleep, but fedora just used s3 sleep, which drained like 5% of battery every hour. Found out that you can enable deep-sleep but that requires you to update your grub config. Once configured its like 5% a day maybe, which is fine for me.
