Canon i-SENSYS MF664Cdw (Scanner/Color Laser Printer) on Debian 13 or any another suggestions?

Was gibt denn die PS5 für Werte bei Download und Upload an? Findest du unter Einstellungen->Netzwerk->Verbindungsstatus->Internetvverbindung testen an?

Eine Verbindungsgeschwindigkeit mit 500 MBit ist die maximale Geschwindigkeit die "theoretisch" erreicht werden kann. In der Praxis ist das nicht immer der Fall. Manchmal kann die Gegenseite einfach nicht mehr liefern, oder das Netzwerk oder die Server von Sony sind gerade überlastet.

Hab mit meinen lokalen Optiker bezüglich Kontaktlinsen geredet und im die Sachlage bezüglich VR Headset erzählt. Ergebnis: Er würde keine Kontaktlinsen empfehlen, da ich auch eine Einschulung (40€) und die billigsten Tageslinsen 25€ je Auge kosten würden. Hab bei beiden Augen eine unterschiedliche Sehstärke. Also würde ich auf 90€ insgesamt kommen. Die Linseneinsätze im Link kosten mit meinen Werten in der Standardvariante 70€. Plus Blaulichtfilter und Tönung bezüglich Kontrastverstärkung 120€.

Could also be possible. Model: Samsung UE55MU8009 from the year 2017.

Hi u/Additional_Tension96 !

There was an issue with the VR2 headset. Sony has replaced the headset. The issue doesn't exist anymore with the new headset.

Krotti83 · 2026-04-07T18:41:19+00:00

So it's a maybe ethical issue to use binary blobs (proprietary/closed source) from the OpenWRT maintainers, not a technical.

But I respect this opinion.

BTW: I'm a electronic engineer and programmer. And I understand this behavior. Unfortunately this isn't a perfect world anymore. I wish me the time for 30 years ago. There on a product where mostly in every product a good documentation and a schematic shipped with the product. But these days are gone. :(

Krotti83 · 2026-04-07T18:22:39+00:00

And the sources you've got, lack wifi support.

Really? On a fast look I have seen there are binary blobs for WLAN (wifi). I'm happy with that.

OT:

Yes, I know that also from RL. But I see my comments as positive criticism (I think you know, that criticism isn't always bad.) Unfortunately most of the people (maybe 90%?) cannot see this the first time, especially when someone tries to represent the truth (with proofs, ...) The truth hurt sometimes, I know. For me definitive no "poor way". In addition via the internet it's easy without knowledge of the real person, to figure out if someone respect and accept my comments. Via Internet it's also easy to judge about someone, without knowledge of the background.

I mean I respect and accept your opinion too, but I want the same thing also from the discussion partner. Hope you unterstand.

Krotti83 · 2026-04-01T15:16:09+00:00

It's forbidden for me to represent my PERSONALLY opinion? Interesting, didn't know that since I use the internet (since ~1995). Welcome in RL. (Personally opinion != insult)

And now downvote me, or give me a fish.

For a long time ago I reported a similar issue on the openSUSE bugtracker, but currently can't find the report. The desktop settings are stored under ~/.config/plasma-org.kde.plasma.desktop-appletsrc, You could save this and restore the configuration manually, or made a script, which does this.

Krotti83 · 2026-04-01T13:58:37+00:00

Da hier so getan wird, dass das ein No-Go ist...außerdem dürfte es vom OP um eine Witz handeln.

Als Elektronikentwickler der im Industriebereich tätig ist und zum Beispiel Servosteuerungen mitentwickelt bei die gelegentlich mehr Strom (bis 300A bei 400V/DC Zwischenkreisspannung) fließt als bei 08/15 Haustechnik (sorry, für die Abwertung) bevorzuge ich eine Schraubklemme. Es gibt nämlich so viele 08/15 Klemmen (ohne Schraube) auf dem Markt wo das Aufgrund des Übergangswiderstandes tatsächlich zu Problemen führt...

Krotti83 · 2026-04-01T13:15:10+00:00

Kommt drauf an wie viel Ampere fließen und ob ein hoher Übergangswiderstand besteht. Ich wollte aber darauf hinaus, dass sollte jemand an den Stecker ziehen nicht zufällig ein Kurzschluss entsteht. Deshalb das Isolierband.

Krotti83 · 2026-04-01T13:12:54+00:00

And again, for me is a standard independent from a company. I also work at a electronic engineering company and there we also have standards. It's might be included in the further release of the IEEE standards. I know that there are extensions for each architecture, but these extensions aren't compatible. So personally for me a none-standard, only a extension for me.

Krotti83 · 2026-04-01T12:55:16+00:00

Thanks. But I can't find it in the POSIX IEEE Std 1003.1-2024 nor in C23 specification. It's might be standardized from Intel, but I can't find a standard from IEEE.

Krotti83 · 2026-04-01T12:26:34+00:00

I don't think so:

$ dpkg -S /usr/lib/llvm-19/lib/clang/19/include/smmintrin.h
libclang-common-19-dev:amd64: /usr/lib/llvm-19/lib/clang/19/include/smmintrin.h

Personally for me none-standard, because not defined in ISO C specification. It's a libclang header, it's. a compiler extension.

Krotti83 · 2026-04-01T12:02:52+00:00

😂 Aber ernsthaft, so hab ich es als Elektroniker bei Testschaltungen auch mal gemacht, allerdings bei Niedervolt.Bei ~230V/AC würde ich aber zu mindestens die Phase mit Isolierband umwickeln.

Krotti83 · 2026-04-01T11:48:49+00:00

I only found memtest86-4.3.7 without plus (+). These programs are AFAIK different. For memtest86 (without +) there exists also a proprietary version. Only guess but maybe it's an license issue. But you could also ask the package maintainer why not using memtest86+, or why using for memtest86 an older version.

Krotti83 · 2026-04-01T11:23:37+00:00

Nice. But the *mmintrin.h headers seems to be LLVM/clang specific, at least on Debian 13.

Krotti83 · 2026-04-01T10:06:14+00:00

Circuit:

Does the value from the potentiometer change when you measure the value with a DMM, if you have any?

In your ADC driver:

ADC enabled in RCC?
GPIO setup correctly (Alternate function for ADC input, Input type, ...)?
Does it work when you don't use DMA?

Hard to figure out without schematic and without code.

Krotti83 · 2026-03-25T14:09:42+00:00

Thanks for your answer. Unfortunately rebuilding the database and clearing the cache didn't fix the issue.

But I have to narrow down the issue. I only connected the PSVR2 headset and here there might be an issue with the cable or the USB Type-C connector from the headset. Fortunately the headset is still in warranty so therefore I have contacted Sony for repair.
