I really *need* to find a new way of storing “secrets”, like short secure notes, etc.
`MUST`:
- macOS client
- reasonable GUI
- text and images (eg: TOTP QR-Codes)
- multiple independent containers for mutually exclusive projects
- OFFLINE capable (even for adding new items)
`SHALL`
- OpenSource
- fast
Would `LIKE`:
- Synchronisation via self-hosted backend (WebDAV, separate server)
- iOS Client
`MAY`:
- CLI
- cost €
Personal experience, and suggestions welcome!

@nprofile…4x07 @nprofile…zx3a Ich finde vor allem planbare Updates hilfreich. zB am 1. und 3. Dienstag eines Monats. Das gilt für Software die konzeptionell im Internet exponiert wird.
Software die in einem geschützten (V)LAN hängt und nur dort, sehe ich entspannter. Monatliche Updates sind da fein.
Kritische- (Datenverlust), Safety-, und Security-Fixes auch außerhalb. Idealerweise mit Ankündigung.
Major Releases (non-rolling): alle 2 Jahre

@nprofile…fnv8 Sure, but I *know* that the printer‘s power outlet is off. Why not let the print job turn it on for me automatically? It‘s bad enough I have to walk oder to collect the marked pieces of dead trees like in the dark ages …

Today's sidequest: Find a way to run a shell script before printing a file via CUPS on macO. The script basically does a single `curl` to power on the printer’s outlet.
Have you done something similar? Perhaps with a filter? I don’t need to manipulate print at a at all, just run a single curl before the job is sent to the printer.
Links to solving this are welcome! (Yes, I’ve obviously searched around and read documentation already, but nothing seems to work so far.)

@nprofile…zx3a Moi? 😇
RC has just been a forever hobby of mine. So I was curious. I wasn’t even aware of Cupra as a manufacturer until now, but I normally don’t follow 1:1 cars. Certainly cannot recall having seen any common RC-Scale bodies.
If you go for that project, I’m certainly curious. :-)

@nprofile…zx3a Is the model at least RC?

@nprofile…4x07 @nprofile…a80x Sorry, Bad wording on my side. I did not mean, and world explicitly not recommend using a large vDisk on local storage provider. Not because of the local storage, but because of the vDisk, which is, IMHO, way too risky at n-TB size.
I‘d rather use VirtIOFS which is available since Proxmox 8.4.0. It is filesystem/file backed instead of blockdevice.
No risk of corrupted vDisk. Will benefit from ZFS on Proxmox. (You’re fine putting it on local-zfs.)
Makes more sense now?

@nprofile…4x07 @nprofile…a80x Either what you do, if possible, other networked storage elsewhere, or local mounts in Proxmox 9.x. VDisks in the TB Range are terrible to use, fragile and easy too risky IMHO.
Local mounts in Proxmox are just not matured yet and not well exposed in the GUI. You have to care for backups yourselves, there’s no integration with normal backups or even PBS.

Für Viele waren die letzten Jahre schwierig.
Um die positive Dinge im Leben besser zu beleuchten finde Dir:
1. Ein Gefäß (Schachtel, Glas, altes Häferl)
2. Notizzettel
3. Einen Stift mit dem Du gerne schreibst
Stelle sie an einem Ort auf wo Du täglich vorbei kommst. (Kaffeemaschine, WC, Kühlschrank, Nachtkastl)
Bilden wir gemeinsam diese Gewohnheit:
- Jeden Tag ein gutes Ding einsammeln! Gedanken, Ideen, Begegnungen, Erfolgserlebnisse oder Liebenswürdigkeiten.

#Whatsmissing is a button in #Steam to allow people to wish that a game would work on #SteamDeck. Shouldn’t matter if it’s in my library (of shame) or my wishlist (of shame).
If it’s a game I’d *like* to play, and it doesn’t support playing on SteamDeck, I’d like a simple and measurable way to let the developers know about that desire.
Same for the upcoming #SteamMachine and #SteamFrame devices.

@nprofile…g7xy Dann kann die nicht so alt sein. :-) Ich hab mehrere Jahre alte Anker PowerBanks die nur 4 LEDs haben und einen Knopf und sonst nix. Sogar die können das schon.
Ich word also mal davon ausgehen, daß ggf. Ein Test da positiv ausfällt. :-)

@nprofile…g7xy @nprofile…a0e4 Kann diese Powerbank keinen Dauerversorgungsmodes? Oft lässt sich der mit einem Doppelklick auf den Knopf zur Ladestandsanzeige aktivieren.
Bei meinen wird dann eine der blauen LEDs grün um das anzuzeigen.

#USBWTF If you thought USB Type-C cables were a complex topic… You have no idea…
Investigating why USB-version connections differ with multiple full-featured, and tested, USB Type-C↔︎C cables.
Cable A: USB-IF *certified*, passive Thunderbolt 3/4, USB4 Gen 3, 40GiBit/s
- Actual connection: USB 3.2 Gen2 SuperSpeed+, aka USB 10GiBit/s. Yes, renamed *again*.
- R: 1000MiB/s
- W: 700MiB/s
Cable B: not-certified, same specs as A
- Actual connection: USB 4 Gen 3
- R: 5.2GiB/s
- W: 4.8GiB/s

@nprofile…fvmu Ich hab’ noch nie einen Yubikey um 35€ gesehen? Auch nicht vor 5 Jahren? Was ist Dein Geheimnis?
Aktuell finde ich sie so um 60€ shipped (YubiKey 5 NFC USB-A)
https://geizhals.at/yubico-yubikey-5-nfc-y-237-a1929165.html
Mit USB-C ein paar € mehr.
Wenn mir wieder mal ein Coupon-Code unterkommt, sag’ ich gerne bescheid. (Was natürlich nicht hilft wenn eins den grade akut bräuchte.)

@nprofile…7v9l @nprofile…cwcm @nprofile…twkg @nprofile…8fl0 I‘m open to suggestions or ideas. Haven’t found a sparkling topic though.
Ruled out:
- USB
- Firewire (surpassed by USB, dead technology)
Extremely unlikely: others know a LOT more about this, or have covered this excellently
- Bluetooth
- HTTP/3 (quic)
On hold:
- Emoji follow up (not enough yet)
Unsure if suitable to convey helpful knowledge that can be applied by everyone:
- Unicode
- Text Encoding
- UTF(-8, -16, etc.)
- data compression
- Colour
