Yeah, in Sweden too.


Norway, too.


I’d say he’s correct, people under 60 that uses cash are considered, if not criminal, at least suspicious, like they have something to hide. Or simply wackos. I haven’t used cash for the last 15 years or so. Except for when I had carpenters at home who wanted to get paid in cash (to avoid taxes, so called black money).

I feel sorry for you and those people.


>"people under 60 that uses cash are considered, if not criminal, at least suspicious, like they have something to hide. Or simply wackos."

I have barely used cash in 25 years. This doesn't mean anything at all. You're probably putting this solely in the context of using cash for significantly large purchases, e.g. higher 4 digit sum or above, or as in your example a craftsman who want to exempt it from his or her accounting. Nobody bats an eye at a person buying groceries, or some gadget for a couple of hundred, with cash.


no we use cards for everything, even for just buying an icecream or something. most older people use cards too actually, but sometimes you can see one struggling with their coins and notes when buying groceries yes.


I regularly see people use cash for common and small purchases. In the grocery store checkout line, at the kiosks, at the pizzeria, and so on. Card is by far the most common option, but the discussion was never about the ratio.


Yeah, that's kind of my default assumption as well. If someone is insisting on cash I'd assume it's for tax evasion purposes.


So do you like always take split bills for everything? Like when eg. 4 coworkers go to eat together (ie. not a situation where one person pays everything)? Over here in the balkans/mitteleuropa you just put some approximate amount of cash on the table. Same for kids, you're not giving a kid your credit card when you send him to a bakery to get bread, you give him a couple of euros in cash.


> Same for kids, you're not giving a kid your credit card when you send him to a bakery to get bread, you give him a couple of euros in cash.

I got caught out by a thing like this, recently. (I'm on the east coast of the US.)

My kids had a day off from school, and it was a nice day to ride bikes. There's a small municipal park around 5 miles (8 km) away, with a nice mini-golf course and a grill/cafe next to it. They were eager to go by themselves, so I told them they could ride their bikes there and gave each kid enough cash for a round of mini-golf, a cold drink and some lunch.

The park was card only! While that has been happening more and more, I was not expecting that from a city park. Thankfully, they're not shy kids, and they persuaded one of the park employees to use a personal card in exchange for cash. But I was shocked. They're 10 and 13 years old... it had not previously occurred to me that I should give them cards of any kind.


In that situation either (1) someone will pay for everyone at the table and then everyone else will “Swish” (the name of the local money transfer app) them their respective share of the total bill; or (2) they’ll just ask the server to split the bill and each person pays for their part. Both are actually quite common, and having lived many years in Sweden, I’ve never eaten at a restaurant where asking the server to split the bill was a problem.


Or, if it's a group that goes out together often and doesn't vary their orders much (in terms of order-of-magnitude of spend), then this will sometimes evolve into a rotation on one person picking up the tab each time.


Reporting for Hungary and Italy here: at the restaurant you ask for split bills or someone pays and the others will just pay back. It's been a few years since this was a problem, shops have adapted.

But yeah you still give cash to kids.


In Denmark someone will pay, and the others will use MobilePay to pay back their share.

But you've reminded me of a case I still use cash: on business trips abroad with a mixed group of people from several countries, most people put money on the table to pay their share.


quite often we pay separate by cards, that is so common the personell even asks if that is how we like to pay. otherwise one pay using his card and we swish (tranfer money instantly using the swish app) him the money.


> people under 60 that uses cash are considered, if not criminal, at least suspicious, like they have something to hide

You are spewing complete nonsense.

Here's some perfectly normal stuff I use cash for in sweden on the regular:

- flea markets

- strawberry stand by the road

- unmanned vegetable shop has a cash bin and a pay-for-what-you-take sign


Denmark would do all that with MobilePay.

But I do see people paying with cash in supermarkets etc, and I don't judge them as criminals. Some people just prefer to manage their money that way.


all those prefer swish payments instead of cash!


I like the idea of letting AI try to formulate new math problems that are interesting, i.e. worthy research level. I guess we are still a number of iterations away till AI get there though..


i agree on that emission-fraud. but, haha, you know there are loads of videos of your favorite blue colored ones doing the same salute? if that is what keeps you spinning you ran out of car brands long time ago...


Please, post links to videos of those, not still frames. I've seen much shorter and punchier rebuttals to this claim, but this is what I found just now:

Musk slapped his chest and quickly snapped his arm straight. Booker gently reached out, does a little dip, crosses both hands across his chest.

But, ok, there are some similarities. Where are the other "loads of videos of your favorite blue colored ones doing the same salute?"


Link one.



Notice how quickly it cuts? I wonder why. But I guess you never did.


Spot on!


As a C++ developer I shrug at those size numbers, but I’m glad you are a happy with Rust.


OP's sort of being misleading when they say they "rewrote it in Rust", IMO. They're still using HTML and JS for their UI, rather than a native solution. The size/perf improvements mostly just come from using the OS' native engine instead of bundling Chromium.


As a rust developer, I do too! Those are not representative of rust GUI/3D etc desktop applications. I've made some pretty complicated stuff with 2D and 3D graphics, lots of functionality; expected size is 5-15Mb on Windows, and 10-25Mb on Linux. Less if you don't need 3D.


Strip the Linux binaries with strip(1).


What do you think would be more in line with what you've seen in the past? There's definitely room to keep optimizing.


<25Mb for the executable. For the use case the web page desribes, probably <15Mb. It usually comes down to dependencies used.


Interesting. I'd love to get our app size down further, under 15MB would be great.


is there a UI framework production ready yet in rust??? because for Tauri at least you can use JS which is fine


yeah slint, which is most similar to Qt

see https://www.boringcactus.com/2025/04/13/2025-survey-of-rust-...


lol when you click through to this site from HN it redirects to https://upload.wikimedia.org/wikipedia/commons/d/d4/Human_fa...

if you open in new tab or copy/paste in new tab it does not.


Funny for sure, but not novel. JWZ also doesn't let his web site linked from HN. Example link (that only works properly when you copy paste, opinionated rejection otherwise): https://www.jwz.org/blog/2024/06/mozillas-original-sin/


EGUI


iced is the best IMHO


Should we do a c++ rebuild


If you use FLTK you can start a binary with no dependencies at 100KB.


That has nothing to do with Rust and everything to do with Tauri.


… and why are those subscription fees so obscene? I guess too many people have too much money…


This. Everything is getting priced for U.S. (software engineer) incomes.


Nice writeup! I was hoping to see a photo of the fractal on your wall.. Nice link to Knuth video that I somehow have missed.


Isn’t that it on the left in the last image?


Yeah, maybe it is. It would be cool to make it much bigger, frame it and put it on the wall. Or create a mosaic tiled artwork, similar to Knuth’s dragon curve wall.


Yeah, it's in the last image and in the thumbnail at very top (which I realize now is really hard to spot on mobile), intentionally not in the spotlight to leave space for the twist at the end.

https://chriskw.xyz/images/fractal/thumbnail.jpg

I think it would work perfectly as a mosaic eventually, but for the time being I'm perfectly content with the "rustic" 8x11 graph paper sized one taped to the wall. Currently planning to put up a slice of the orthotopeflower as a companion piece once I find matches for the colored pencils I used back then.


What was the name of the site again?? Other than that, ehh small detail, it seems pretty ok.


So few of the greatest books that shaped a Century of Science...
