With all due respect, the transactions above that rough amount is exactly those I would want the government to keep an eye on, while letting me buy stuff for a few hundreds freely and without having to report it.

There is pretty much no situation whatsoever when someone buys something for more than 3k€ where the absolute requirement to use cash is not linked to some shady reasons.

Articles like these would be a lot shorter if Alpha had never existed. A significant chunk of this complexity is attributable to Alpha and its goofball ability to reorder loads and stores in ways that programmers never wanted. There are details of the C++ memory model that are impossible to observe on any hardware that exists today.
EU citizen here and I don't remember electing you to represent my opinions. EU is not a hive mind and different people from different jurisdictions have different point of views on this matter. Here where I live people appreciate having access to cash because they don't trust their government.

Apologies if that sounded rude but Its often that I see people claiming to be EU citizens or sympathizers dropping the most arrogant takes. To the point I prefer to browse this website after 7PM in my timezone to avoid "the EU-only HN time".
The things I've found are productivity and reliability multipliers are:

Unit testing - and the modularisation that it forces you to do. It's great to unit test C not just because it tests your code well before it runs on hardware, but also because it's basically impossible without embracing dependency injection and modular "object oriented" C. Personally, working with a bunch of higher level languages - Rust, C#, Scala, Python - and the tooling that they have gave me a much better understanding of how things can be done. I'm a big fan of Ceedling - http://www.throwtheswitch.org/#download-section

Writing firmware which can target a desktop environment. The hardware dependencies should be a small part of the project, and easily replaced with fakes or simulators.

Having a CI pipeline which runs tests/linters/builds for you.

Those aren't necessarily easy to insert into an existing project though. Honestly I think the most useful thing is just building projects using other languages, and taking the best parts back into the low level code. It depends a bit what kind of projects you're working on - if it's mostly just glue between peripherals then these approaches are a lot less useful than if you're doing complicated maths or json parsing or higher level stuff.
Dev / Stage / Prod is the wrong pattern for data pipelines
Or sometimes an instruction isn't in the compiler because the hardware has some strange corner case failures so they aren't using it. I would be nervous about depending upon an unused instruction.

Yes, fractional reserve banking should be reformed, and that's a reasonable preference. However, my point is that it's also reasonable for people to want to have physical possession of their assets.
Even if you're having a new house built, you get a lot less choices than you might think. To most builders, "custom home" means you get to pick the paint and flooring, not that you have appreciable input into anything structural.

I'm sure it varies regionally, but where I'm at (Kansas City market) you have to be in about the $800k range, generally, to be able to work with an actual architect and build something custom - and that's just plain out of reach for most people.
I used Kate before for C++ development, there isn't much about it, it just gets the job done, I don't rely on the editor/IDE to do anything other than edit files so any editor works for me. The thing is, it isn't as eye-candy as VSCode is/can be, I know that technically this isn't a crucial feature but UI does affect my software choices.
Also, does Kate look the same on all supported platforms?

This is a great comment. I was self-taught and then went back to school, so I have pretty good experience with both paths.

I hear a lot of time from developers "I never use those fancy algorithms!" or "I've never needed any math beyond HS algebra!" but I find that very often it's precisely because programmers aren't familiar with those solutions that they don't see the areas they can be applied to.

One of the biggest insights from my after-self-taught CS degree was that one class in particular stands out as a the dividing line between feeling knowledgable and not: Compilers.

To anyone wanting to improve their CS background: If you can't get back to school full time, try to audit a course on compilers (this is one area where having a structured course really helps). Pretty much all aspects of Computer Science are touched on in that one area: algorithms, data structures, graph theory, theory of computation etc. Plus it's just a lot of challenging programming to be done.

But once you see a high level program that you wrote compiled to assembly by a compiler that your wrote every piece of, you really feel like you understand both CS and software.

> The answer to this is very simple: none of your business.

It kinda is. Paying something $10,000 cash strongly suggests you’re buying something illegal, or you got this money illegally (not necessarily unethically, but still illegally).

That the only argument you can find is « it’s none of your business » doesn’t exactly play against this ruling.
Charlie Munger and Warren Buffet are also one of those outliers in terms of diet, exercising and work rate.

Granted they receive the best medical support money can buy, but they are on record saying how much they binge on fast food, and Munger in particular mentioned on several occasions how he never intentionally did any exercise (no cardio or weightlifting) since he was a teenager. They are both also crazy workaholics working a rigorous 9-5, very little holiday for the last 7 decades.

The entire purpose of designing your own house is to take these things into account. If you're looking for a cookie-cutter generic design, just let a mega builder use one of their templates and they'll get what you're talking about here.
Maybe it's me, but this feels counterintuitive. As mortgage rates go up, demand falls, and then prices fall. That is, at any given moment, the total cost of the mortgage remains same-ish.

But. Most importantly, eventually, you'll be able to refinance at a lower rate. That is, you're getting a home priced for, say, 7%+ market, and paying for it at, say, a 5% rate; which also likely means your home will increase in value because demand has returned.
I've tried a number of approaches but the one that has worked for me: try and build a software product / company with commercial application. Even if it doesn't work out the economic incentive of finding PMF will give you all the motivation you need to keep plugging away at learning whatever languages, frameworks required to convert your idea into a functional software product.
The damage is already done by not enforcing "All merchants must accept payment by cash". By accepting that any shop can say "we dont accept cash", we have already lost that freedom to pay by a not easily trackable form.

I wonder what more this law is hoping to achieve? Stopping that one guy who buys 10 laptops with a bag of cash? The merchants are already required by law to report any transactions above a certain amount made by cash.. so it is nothing new.

If I sell my car on Marktplaats, I cannot accept cash? is that it?
You can deposit whatever amount you want into your bank account, they just might ask questions regarding where the money came from, and if you show that you sold products there's zero issues.
"In a recently obtained letter (pdf) sent in November 2021 to the Centers for Disease Control and Prevention (CDC), top epidemiologist Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, and seven colleagues informed the agency it was promoting flawed data and excluding data that did not reinforce their narrative."
This is one reason why low cost and efficiency are just a nice-to-have when it comes to to space exploration. Moreso the farther you go. A unique mission like a lunar polar landing should be conservatively engineered, where that is possible, on the first try. Early optimization and space exploration don't mix.
A cash deposit into a bank isn't a payment.
> I don’t see an iPhone or similar device getting OCT-like images anytime soon. They need special optics to image the whole retina (although I can imagine image processing hacks to work around that at the expense of exam speed), but they also require an optical system that’s quite unlike a normal camera to acquire an image at all.

Bootlicker mentality. Your inability to fathom the way others spend their currency shouldn't result in your support for arbitrary restrictions.
> Because I pay cash and keep the bankers out of the transaction it costs me less and it costs the seller less.

Other way around (in the Netherlands, which is the subject), bank transfers are free but depositing cash as a business costs money. Paying cash costs the seller more and holding it has a risk of robbery.

Please do not buy a special device for navigation.

Use an old or a cheap smartphone or tablet with GPS. Install a decent navigation software with offline maps (e.g. Osmand). Remove the sim card. Turn off Wifi. Familiarize yourself with the software so you don't get distracted by any obscurities while driving. Try it out before you go on long trips with it. With Osmand, you can even freely customize the user interface to suit your preferences and needs.

If you use it like a navigation device, it won't be more distracting than a navigation device. And it's a good way to reuse old hardware.

what it means is less important than the real questions it raises.

- if in the united states we refer to our prisons as 'correctional' facilities, what quantitative correction could require nearly a century of internment?

- if by any study it costs nearly 40,000 dollars to house a prisoner for one (1) year, was the night watchmans life truly worth 3.2 million dollars of Connecticut taxpayers money?

- what meaningful value was extracted from his slave labor? was it enough to offset even a fraction of the internment cost?

- Can the state identify how or if a nearly 100 year old man has been rehabilitated in their correctional facility? has the process improved?
I absolutely agree. You need to solve hard problems to strengthen your problem solving skills.

That is not true in most of Europe.

Money you deposit in a bank is guaranteed by the state up to a certain limit (often 100 000€ per person per bank).

Playing devil's advocate: that's as long as the denomination doesn't change. Once it changes (for instance Cr$ -> NCr$ -> Cz$‎ -> NCz$‎ -> Cr$‎ -> CR$‎ -> R$, and I lived through most of these changes), and you're outside of a conversion grace period (when you can take your cash to a bank and exchange it for new notes), your cash is worthless; if I find an old Cr$ bill stashed somewhere (I probably still have some), they're not worth much more than the paper they're printed on. If your money is in a bank, on the other hand, it will always be converted automatically and transparently.

(On the other hand, I also lived through the infamous "confisco da poupança" which froze most of the money in everyone's bank accounts, so I can clearly see the importance of having money outside of the reach of banks. On a third hand, I also lived through the hyperinflation times, and know that having too much of your money not deposited in an interest-bearing bank account or other similarly good investment means it will lose its value quickly.)

No self respecting company buying those goods would do cash transactions to a business in the Netherlands. All perishable goods are tightly regulated and cash payments make that harder to administer.

Paying your various-shades-of-grey farmhands is another story.
> This is targeted at law abiding smallholding farmers where roadside transactions are often done in cash

Where (in NL) do you find farmers who routinely need to accept >3k in cash and are (somehow?) unable to accept electronic payments? Pretty much everyone everywhere can accept at least one form of electronic payments. That's a legal requirement for any business in Belgium, and I can't imagine the Dutch being that far behind on that ...

Even if you can't take card or contactless payments or apps, you can do instant bank transfers with most banks within the EU ("Instant Payments"), either free of charge or pretty cheap. There's no excuse for being unable to accept non-cash money. There are, however, plenty of reasons to be unwilling, but that's another story.

Having been involved in some of those enterprise product evaluation decisions, that isn't how it really works. What they do is gather and prioritize a huge number of requirements from various internal stakeholders (some of which have the power to block the project if they don't like where it's going). And many of those requirements really are "must haves" to run the business, or even achieve legal compliance. If a product doesn't meet the key functional requirements then it's a non-starter regardless of usability or simplicity.

I worked with Scott at a startup he co-founded after Sun. He's a good guy.

I remember him telling me a story about when he first met Tiger Woods. Their wives were college friends so Tiger and his wife visited the McNealy's at their home in the Bay Area.

It was later in the evening, the sun had set (no pun intended), and Scott, being a huge golf fan (his son is a pro golfer now) was picking Tiger's brain. The next thing they knew, they were chucking balls off of Scott's back deck onto the roof of the neighbors house and then running and hiding, giggling like two pre-teen boys making prank calls.
