A software developer and Linux nerd, living in Germany. I’m usually a chill dude but my online persona doesn’t always reflect my true personality. Take what I say with a grain of salt, I usually try to be nice and give good advice, though.

I’m into Free Software, selfhosting, microcontrollers and electronics, freedom, privacy and the usual stuff. And a few select other random things as well.

    Does your bank even allow you to file debit notes, or collect money from other people’s credit cards? As far as I know that’s never part of a regular consumer bank account…

    For payment in advance (if you clients put in the effort to do a bank transfer) I think there’s HBCI, FinTS or whatever standards we have integrated in some CRM and eCommerce solutions.



  • I don’t think so. I did a secure erase on my Samsung SSD and I forgot how long it took, but I still remember being surprised how quick it was. I think it was quicker than overwriting the entire disk, even with zeros. I even double-checked whether it did it because it was done so fast. But yeah, it didn’t return any data after that.

    I mean I’m generally not a big fan of all the compromises. Sure maybe most of it is deleted. Maybe it’s not that easy to recover the rest of it. Maybe there’s an easy tool out there… I mean the issue with it is, we have all kinds of personal data on our laptops. One nude left, or the tax filings document and you might be in trouble anyway, if you do some half-assed compromise. Maybe you’ll give it to a regular person and nothing will happen… But I think generally it’s not good advise to hand out to people. They might not be aware of all of the consequences, we might not know the full picture… And the exact phrasing is doing way too much heavy-lifting.

    Luckily there’s a clever way. Use LUKS and encrypt your disk right from the start. (As OP did?!) That takes care of everything. And once you give it away, just discard all the blocks. Mainly as a service to the next person, because that’s going to make the drive fast again. Should also be the fastest option, since SSDs do TRIMs all the time and are optimized for it. Quicker than a dd over the entire drive.

    Not really great on SSDs, though. It’ll likely make them slower because now the controller thinks 100% of the memory is allocated. And some small percentage of the data will still be around, because they do overprovisioning.

    Shouldn’t matter for OP, though. If they set up LUKS properly, there’s no way to decrypt the data.

    But I mean secure wipe isn’t hard… It’s copy-pasting 2 more commands from the Arch wiki, compared to the dd command.



  • Dunno if it’s necessarily worse tech… I don’t really care if it’s physical tokens which get exchanged or virtual ones… Point is, it has to work and cover a wide array of use-cases. Has to work in edge-cases, for both residents and tourists, has to work when there’s surprise maintenance at the bank, when there’s an internet outage… We gotta easily pay $1000 for a hotel for 10 days and the rental car, or 73ct at the local flea market. I might need to pay for a bus ticket or gasoline in the middle if some forest where there isn’t any 5G coverage…

    I think exchanging physical tokens is just absurdly good at that. I’m just not sure if it can’t be done any other way? I mean we obviously don’t have that hypothetical tech in the real world, because banks want to control the process and they always come up with some central way of doing it, with them in the middle. That’s kinda their business model. And the alternative concept is some convoluted approach which needs an internet connection and a decent amount of resources to do the transactions…

    There’s some better approaches at digital cash like GNU Taler I think that one is pretty much like cash. And we only need one of the transaction parties to be online (to prevent double-spending of the virtual tokens).

    Edit: And we need some default. Makes it way more comfortable to live in a country that just demands people to offer a payment method and I can go anywhere and just pay with that. In contrast to install 25 different apps, open 20 bank accounts to cover all possible cases, and the parking meter at the tourist place randomly asks me to install the 26th app.

    Yeah, I doubt anyone runs it, because if you follow the instructions and click on the link to the server code, it’s just missing. And the empty repository has been sitting there since May… There isn’t any Android app in the Appstore either, so you wouldn’t be able to install anything. Seems all “Circulus” is, is a shiny website with (made-up?) advertisement text.

    (And by the way, if you decide to self-host some of the standard open-source messengers… You can always just disable Federation and disallow sign-up. That way XMPP or Matrix won’t be able to connect to anyone else, except the people you invited to your server. And there’s this messenger overview, it doesn’t talk about kids-features, but maybe it’s useful nonetheless: https://www.messenger-matrix.de/messenger-matrix-en.html )


  • Yeah, Some people here really love drama and to fight other people online, preferably on a personal level. PieFed has become target of that. I don’t think it necessarily means a lot, other than we’re some high drama online place. There wasn’t any one software vs another one involved.

    But everyone is allowed to pick their favorite software. They’re both fine from a technical perspective. You’ll get some different perks, but it’s all the same Threadiverse. I myself like PieFed better, including which side of drama they end up on. But YMMV. If OP wants to start on a new journey, they’re entitled to do whatever they like. Main thing with side quests is to do something in the first place. That’s more important than the exact details.

    (Btw, I’ve also been using Lemmy for quite a while… It’s not like I’m in my comfort zone all the time.)

    Yeah, maybe I’m wrong and there is some drama. Googling for “Linus Tech Tips drama” yields many results. I must have missed it.

    Some of that sounds like average stupid people behaviour, like not being able to wear seatbelts properly, or skewing benchmarks. I’ve seen all the Honey ads as well, I always thought that’s how YouTube is, and didn’t make up my mind about it. Having some sort of boy culture and being unable to learn sounds a bit more unfortunate and worrisome. (If true.)

    I think it depends a bit on what you’re looking for. If you want Linux content, LTT might not be your thing. Linus is a bit of a notorious Windows user. They did a few videos on Linux, but that’s not really what the channel is about. I don’t think they’re bad people, though. I’m not aware of any constant controversies. There might be some drama here and there, idk.

    It’s a bit below my paygrade, so I don’t watch them often. I’m not into building new computers every few weeks, gaming, or optimizing my Windows file transfer speeds. And I don’t think I’m their target audience when it comes to explaining computers. I already know all the stuff they explain and some more. The episode featuring Linus Torvalds was great, though!

    (Edit: But yeah, thinking of it, maybe skip their Linux videos. I remember disagreeing a lot with how they portray stuff. Especially the older videos barely scratch the surface and I think some stuff Linus says is plain wrong. They have one dude in the team who uses Linux and knows what they’re talking about. But that person doesn’t get a lot of screentime.)



  • Well, I am a German and I can tell you there’s lots and lots of fellow Germans who don’t speak English very well. There’s also some who do. But I wouldn’t say we’re anywhere close to some other European nations.

    And a decent amount of people are genuinely straightforward. Might change if they’re on “vacation mode” though. And they feel like everyone else is supposed to serve them for 2-3 weeks?!

    We also have plenty people around who act like idiots, idk whom you met 😆 I see them each day stop right at the top of an escalator, be unable to operate their car properly… Let their dog shit on the sidewalk. It’s a thing. I’d say the vast majority of people is fine, though.
