At least in Germany as far as I'm aware all banking cards are in fact "simple" visa cards who uses "V-pay", since 2012/2014?
Personally I "like" or prefer V-pay because it made payment in the EU more easily for me without the need of a credit card even 8 years ago.
Since the pandemic, I only pay for a (real) credit card (with daily billing) because some goods or services can only be paid with a "real" card, like more expensive cars at a car renting company or sometimes hotel rooms and the like.
In general I try to pay with cash so nobody needs to pay extra fees. But more and more smaller businesses prefer electronic payments. Then I use the banking card with V-pay and to state it again, the real visa card is only used when no other options are available.
Processing cash is by far >not free<! In fact, it costs a lot of money due to all the things involved (counting/collection/recycling etc). Anf it inwolves additional risks for the handling party.
In the past I handled cash as an employee and as a volunteer. Like even a quiet night at a bar can sum up to a few thousand EUR.
Yes handling cash is not free.
But compared to some charges or fees it's often quiet cheap.
Sure you need to think a head like how much small change money you will need or how much cash for change in general.
You also need kind of routine and flow for counting and handling but even if I had to count up to 10k EUR in small bills t does not needed more then half an hour incl putting it into the safe or on the way home putting it into the banking machine...
At least in Germany it's not that big of a deal breaker.
I know of a large restaurant chain with some "bigger" branches: They often have to count two or three times with different people to be sure, that the amount is correct. Every evening.
Then you have transport companies which pick up the cach (or refill ATM) - you pay there for every time they stop, and you pay a tiny fraction per bill processed etc. (though, most restaurants do not use these services)
Then you finally have the very high risk of getting robbed.
You just triggered my PTSD. Worked in a gas station in college and changing over the till was a PITA -- I had to account for every cent, could be written up over 50 cents (too much or too little) and it was always this crazy dance to change over when we were busy since it messed with the counts.
I know: It is just hell! There is a gas station near my location, which closes the door from 23.45 to 24.00 for just doing this and handing over to the group.
That time costs money, the safe costs money, having cash attracts criminal elements like robbers or dishonest employees, your employee might get robbed on their way to the banking machine making it a workplace hazard, security guards costs money.
In 2009 Sweden had 58 armored car robberies, in 2018 there were 1. This used to be a big concern in Sweden, now it's basically a nonissue.
There were 1154 store robberies in 2009, in 2018 there were 515. Muggings are also down considerably. 2022 was the first year with zero bank robberies. This is mostly thanks to the much lower use of cash.
People often say that but does the cost for handling cash really scale (even approximately) proportionally with the number of transactions or revenue?
Or is it more binary that you have to decide, you either handle any cash and have the cost associated with it, or you refuse to take cash at all?
If the latter is the case, then avoiding cash altogether seems somewhat unrealistic where I am from. And if it doesn't scale then it makes a lot of sense cost-wise to try to do as many of your transactions with cash as possible.
Depends on, sure there is some "efficient frontier" where it flips.
Think about all the supermarket chains, handling millions of cash daily; in my region, those are relying heavily on outsourced cash recycling companies - why? Its more effort/cost if they would do this themself.
I'm quite opposite. I avoid any places that don't accept card payments, because it usually means they are avoiding taxes. And I don't have cash on me, or wallet. Only phone or sometimes only my garmin watch (with garmin pay).
No we don't have that much time.
Over time there will no longer be huge areas of new star formation.
Most stars are also rather short lived and can not sup6a plane like planet Earth.
Our sun, sol, has a neat live span so we can thrive for while if we don't **up this plants ecosystem.
But as far as I understood astro physics we are rather quiet early in the game.
No. Just no.
If ISP would have deployed IPv6 early enough in time, like deutsche Telekom had a properly IPv6 network ready in 2012 or even before. And dual stack is no issue. But as always the ISP does need to not fuck up and you operating system should follow RFCs.
All these transitions methods are far to expensive and an unnecessary overhead.
> If ISP would have deployed IPv6 early enough in time, like deutsche Telekom had a properly IPv6 network ready in 2012 or even before.
I think you forgot half a sentence here. What was your point?
> And dual stack is no issue.
How can that possibly be so? Having enough address space to comfortably architect gives you room for far superior topologies, meaning that running dual stack at the bare minimum means that either your IPv6 topology is being compromised to map cleanly to your v4 topology, or that you're running two different topologies altogether. You need two times the sets of firewall rules, two times the number of address configurations...everything in your infra roughly 2x.
> All these transitions methods are far to expensive and an unnecessary overhead.
How so? Running 464XLAT on a device with a proper CLAT has minimal overhead, and the PLAT is no worse than running a NAT for IPv4.
Running nat on ipv4 is no worse than running a stateful firewall on ipv6 only, I don't get the complaints about it. Modern firewalls do far more with deep packet inspection, SSL unwrapping etc. NAT is a hardware function on enterprise access switches let alone firewall layers, any home router would have to do firewalling at their router anyway.
Well performance really isn't something I would point to at all. While I believe it can become problematic with great scale (e.g. those expensive CGNAT boxes), it's more the architectural and connectivity aspects that are problems:
Architecturally, dealing with two different address spaces is a complication. A flat address space is easier to reason about and more flexible. This is amplified by the fact that IPv4's RFC1918 address space is very small. Have you ever had to merge IPv4 networks from different companies? It's rarely the case that they don't have overlapping ranges.
Connectivity-wise, stateful IPv6 firewalling is very different from NAPT in IPv4 because the applications cannot reason about the ports being used (without rendezvous servers).
I'm not advocating dual stack either. Like I said in my other reply to you, I am suggesting IPv4-as-a-service using standard translation technologies and architectures.
It's cool that you have not encountered any issues but especially birth control pills are also no smarties but many use them as they were candy.
In my personal circle I only new of a single woman who had no issues. The majority had all flowers off issues. During and afterwards. No most of the time it got downplayed or simply ignored but doctors and society a like.
I'm personally glad that birth control pills are not longer sold as a wonder pill because many woman suffered needlessly and the worst part is that many did not knew that is was the pill in the first place.
I have no proof on hand but I have seen for instance a documentary on the French German station ARTE tv where they featured a kind of crazy dude who have gone through more or less every oral story of a tribe, the western world actually have written down.
Then he started to compare and traced bits and pieces and this is really crazy who many parallels you will find.
He then together with anthropologist estimated how old these stories might could be, based on travels and migrations like those of the caretakers...
I don't want the miss the young girls skills but she is no security researcher but in the eyes for her target simple a hacker.
And I would say too that she got lucky. It would not be the first time that inexperienced young persona have to suffer the consequences even of their well intended actions.
Yes but then you have to take extra care of this one special system which generates the key on this local system and which transfers the key material to the HSM. Sure it's a valid use case but depending on your requirements this could be a no go.
But sharing key files with developers comes also with a price tag.
I don't get the down voting. This dude is correct. An "engineer" is typical like a "doctor".
Yes I also carry the "system engineer" with me, and yes I have university background, but it's far far away from any serious engineering what's usually done by computer people.
I would also argue that an engineer more or less knows what he's doing and can predict the outcome. Most people I observe while they use a computer it's literally a monkey beating metal with flesh....
It's a protected title in several european countries but I've never seen enforced, despite myself being part of an officially sanctionned body of engineers.
Afaik claiming to have an MD (for obvious reasons) or a PhD would land you in hot water much, much faster, despite technically being exactly the same "offense"
Let's accept that engineering has 2 different uses and that's okay. If I tell people that I'm a civil engineer with nothing to show for it, it'd be as big of a problem like pretending to be an MD. For software engineering, however, you'd just be at the start of your career.
OP is in the US where the term “Engineer” does not convey the person is certified or has professional training.
That doesn’t mean that certain professional engineering disciplines exist that are regulated in the US. Systems Engineer, Computer Enginner, etc are not in that realm.
In the US, engineering is regulated only where public safety is directly at stake. Most engineers work for companies that assume liability for their work.
I too have a real credit card to be able to rent for instance "bigger" cars like even an Audi A6.
Most often hotels also block 500 Eur, or they state upfront that you need a proper/real credit card and not just a debit card.
That's for me the only reason I have VISA and use it like 3 or 4 times a year...
