I still work in finance. This is nowhere even close to the worst thing I've seen just this week.

What is the worst thing you saw this week?

Some code I wrote and the bugs I didn’t knew I wrote into it at the time.

Yeah, I believe it's very unlikely that this young guy had this much on his account. You do not get rich in Sweden.

It's really not an exorbitant amount of money, but even if he had it it seems unlikely he kept it in a savings account on Swedbank.

A bug in dealing with fixed point numbers that caused a price to be off by a factor of 10^8.

It has changed a lot over the last few years. In a typical supermarket in Berlin you will see that the majority of customers pays electronically, these days. Adoption rates may be lower among older people and in rural areas, though.

Berlin is not really as conservative as the rest of Germany, especially that so many foreigners live there which makes it seem so much more progresive and is not representative for the whole ~80 million people country but is more of an outlier (even Germans will tell you that Berlin isn't very 'German'). If you go to smaller cities the situation is vastly different. In Austria I only see cash being exchanged at the s…

Here in Cologne I see most people paying with debit cards, with the exception of very old people.

I'm sure most all of us have one or more personal stories like this, but many seem to forget them and focus on the schadenfreude.

Sometimes shit just happens. Sometimes it's blind ignorance and an accident waiting to happen, sometimes it's a bad code review process. Seems to me it's seldom really the fault of the person making the commit.

This is definitely fuel for Germany and Austria where cash is used everywhere almost exclusively.

I think the change can be observed through retailers like Aldi now accepting card payments, which was not true until very recentrly.

Oh I had one of them a number of years ago on a well known e-commerce company’s back end ERP. Financial values were stored in int64 with the decimal position offset stored in a byte separately. The library that handled these values was poorly implemented so if you added values with different offset sizes without converting them and checking for overflow possibilities it’d do all sorts of undefined shit.

I put a simple assertion in as a precondition check and this fired over 20,000 times within an hour of deploying it leading to several months of fixes, horrible discoveries and cheques written.

1M Sek == ~97K euro... not absurd

SEB is also quite a boomer bank? Still stuck with legacy numeric "usernames", manual limit changes from the office etc..

Username is your national id number, not really something strange in Sweden for banking.

OpenBank (part of Santander) also does this.... together with a 4 digit (only) password for internet-banking. Didn't know how fast I wanted to cancel that account after requesting it.

Cologne is also a bit bigger, out in the smaller towns around Cologne they still pay with cash most of the time. But last year I did notice an increase of card payment at the supermarket. At the local baker and butchers you can forget about it though, they don't even have a terminal for it.
