@nprofile…kcun keep the old code safe. I once started a refactoring/rewrite and it didn't work out as I hoped it to...with no way to go back because I f*d up my repo 😁

@nprofile…leww where is that forest located?
Partly because I'd like to own one, partly because I believe there are differences in what you are obliged to do depending on the state.
As far as I know you can lease out the right to farm the trees with the obligation to do the upkeep. That way you earn some money from it and don't need to do the work yourself.

@nprofile…nhea isn't 100m/s equal to 360km/h not 380 km/h? Just referring to the alt text.

@nprofile…xsvj das Original ja, da wird es als unabhängiges zweites Instrument für Fluglage, Geschwindigkeit und Höhe benutzt. Mein Nachbau ist für den Simulator, da würde ich mich in der Luft nicht drauf verlassen wollen 😁

Original und "Fälschung". So langsam wird der Prototyp was. Ein Druckteil fehlt noch, dann kommt der Rest der Elektronik dran und danach dann die Software.

@nprofile…xsvj es schaukelt sehr und an den Gleisen wird Müll verbrannt... hätte jetzt fast gedacht du bist in einem Regionalzug irgendwo in Deutschland. Aber digitale tickets *und* funktionierende Sitzplatzreservierung, das wäre unrealistisch.

@nprofile…d2rl @nprofile…skw6 @nprofile…ty3t irritating to see that migrating back to Germany now looks like a good option 😑. Down under sounds fine as well.

@npub17lg…9uux all that stuff that doesn't even remotely need a Windows installation to do it's job running most likely fully licensed Windows installations and endpoint protection is wild.

@npub1sly…t8j7 habe gerade so ein Projekt hinter mir, längst nicht mehr am Leben geglaubte Infrastruktur in seltsamen Projekten sammeln und abmanagen. So heißt das also richtig 😁

@npub1xl5…wsca I know the 16GB are used "differently", but that's still an unacceptably low amount of RAM for a premium laptop, isn't it?

@npub13d8…ycpx the only real benefit I see is generative AI writing better emails.
My prediction is an Emotet style malware that uses a LLM to generate even more convincing emails and attachments in existing chains/conversations.

@npub1hxf…g8qu SVG support really is an underappreciated attack surface. It does JS, CSS and everything else. I'd not be surprised if Internet Explorer would execute a VBscript inside an SVG.

@npub1a2r…hng9 wir leben in der Zeit, in der die Telefonie für die ersten Menschen größtenteils aus dem Leben verschwindet...allerdings dachte Ich bisher dass Arztpraxen das Telefon wie Behörden das Faxgerät noch 20-30 Jahre durchfüttern.

@npub17lg…9uux I'm so not looking forward to the IR engagements we will have for this one. Seemingly if you run NetScaler your whole net has to be sub-par.

@npub17lg…9uux is there a good write-up on indicators already? How can you detect that this happened on a machine?

@npub1xl5…wsca that's an interesting one!
I'll look into the C3 in more detail.
I was hoping to find something even more compact than that, quality is a concern, but anything is a step up from freeze dried coffee already 😅 manually operated is a must of course.

@npub1xl5…wsca any recommendation for a compact coffee grinder to get one french press worth of rough grounds? We currently use a "normal sized" medium quality amazon White-Label thingy. Size constraints are based on the fact that every bit of space is valuable in a camper-van kitchen cupboard 😅
