DasIch··on German online bank uses Bitcoins to transfer loans
Miners don't get paid anymore?
DasIch··on Database constraints: The last line of defense
No.
DasIch··on Tokyo to build 350m tower made of wood
Wood also just burns, slowly. Steel might not burn but as it gets hot it loses structural integrity very quickly.
DasIch··on Life expectancy in America has declined for two years in a row
This is something also covered in the podcast. Instead of an over-prescription problem you now have a heroin/fentanyl problem which was expected but assumed to be temporary without prescription pills as an introduction to these drugs. It doesn't look like solving the over-prescription problem is helping at all though.
DasIch··on Front-end Microservices at HelloFresh
I would really like to know why they decided against the Zalando approach. Mosaic is open source, so they could have taken advantage of the same code Zalando uses and gotten improvements there for free.
DasIch··on Front-end Microservices at HelloFresh
Not sure about HelloFresh but at Zalando there are rules for that all fragments are supposed to follow so that this doesn't happen. In practice that means everyone has to use React in the same version, there is a shared library of components for grids, buttons to achieve consistency in look and feel and so on.

You could have multiple SPAs in the same page but you don't actually do that in practice.

You do this not because this is simple, not to create a better user experience but so that you can have 100+ teams working on the site without them being stuck because every change needs to be carefully coordinated with everyone else.

DasIch··on Reddit Bans Nazi Groups and Others in Crackdown on Violent Content
Indeed as a German the idea that some people think appeasement is the right strategy to combat nazis is astonishing. You don't talk to nazis, you destroy them.
DasIch··on Micro Front ends – extending the microservice idea to front end development
Zalando does this as well with Mosaic: https://www.mosaic9.org

If you don't have a few hundred people working on the frontend in many different teams, don't try this. This first and foremost solves the problem of coordinating and communicating between these teams by eliminating (some of) the need to do that. There is nothing to gain and a lot of overhead to deal with, if you're in a company without so many engineers.

DasIch··on Compute Engine machine types with up to 96 vCPUs and 624GB of memory
There are quite a few problems where you need a lot of memory and CPU performance for just a relatively short amount of time like a few hours per day or even just a few hours per week. Forecasting or complex optimization problems for example.

In these cases the amount of money you spend on hardware virtual or otherwise is negligible. Depending on what you do it might just as well be a rounding error.

DasIch··on Cosette: An Automated SQL Solver
You'd need to prove that a DBMS executes a query always correctly to begin with. That in itself would be quite the task.

Additionally SQL as supported by some DBMSes (e.g. Postgres due to recursive CTE and window functions) is turing complete. That makes proving equivalency in general a bit challenging.

DasIch··on Cosette: An Automated SQL Solver
That's not at all what this does and it's not possible to do either.
DasIch··on Amazon's Sick New Sick Policy
Sick days don't exist in Germany. If you're sick, you stay home for as long as necessary.
DasIch··on Amazon is using peer pressure to keep German workers from calling in sick
An employer can ask for a note on the first day, there is no law against that. Employers don't do that because it's incentives sick employees coming in which gets expensive when all of them do stay home.
DasIch··on Difficulties accessing medical services as an EU immigrant in Germany
Registering and having health insurance are completely unrelated to each other. Additionally registering in Germany is actually a legal requirement, having health insurance is not (under certain circumstances).
DasIch··on Difficulties accessing medical services as an EU immigrant in Germany
She's not registered, she doesn't have a job and never had one. In other words she's a tourist and is treated as such.

That's not a bug, that's a feature and the system working exactly as designed.

DasIch··on Blink-dev – Intent to Ship: SharedArrayBuffer
The amount of time something takes is often related to the input. Measuring the time, gives you information on that input.

For example measuring the time of a=b with constant b tells you roughly how large a[:n] such that a[:n] = b[:n].

DasIch··on The Arrival of AI
Stratechery is not the best source for accurate information on the technical details but it's also not trying to be. Anyone who focuses on that is missing the point.
DasIch··on German traffic light stays red for 28 years (2015)
It does not have a right turn only sign. It just has a green arrow.

The only reason you can only ever turn right is because the light stays red, if it were to turn green you'd be allowed to cross the intersection in any direction.

There are also different rules that need to be followed when crossing the intersection on account of a green arrow than, if it were merely a turn right only situation.

DasIch··on A little-known iPhone feature that lets blind people see with their fingers
Apple has control over the hardware, the operating system and their own apps but not over the entire ecosystem. This gets them far but only so far.

The big difference they've made is that they've created tools to make integration with Voice Over so easy, that it's a no brainer to do what little work needs to be done to make an app accessible and to increase demand for it.

They've managed to turn a burden into something that has an obvious economic benefit for app developers.

Also I'm fairly sure that there is actually a good RoI. It might not be massive but in the long term having the monopoly on phones for blind people surely pays off.

DasIch··on From AST to Lossless Syntax Tree
The lib2to3 library provides concrete syntax trees.
DasIch··on Making More Outside The App Store
What if an independent app store, fails at adequately stopping malware from getting through? Is Apple going to ban the entire store then? Does Apple get to do that job for those stores instead? If the latter, does the App get reviewed both by Apple and the independent store? Does Apple get a cut in that scenario?

How do you install independent app stores to begin with? Do you install them with he App Store? That would put them at a disadvantage similar to how Microsoft put other Browsers at a disadvantage with IE. Do you provide a choice then when you setup the phone?

Purely from an anti-trust perspective I can see why the idea of independent app stores might seem appealing at first glance. Thinking about this just for a moment brings up so many questions though and I don't see how you can possibly come up with satisfying answers that lead to good security and a good user experience.

DasIch··on Making More Outside The App Store
> [...] very hard to sift through for the normal customer.

Maybe it's just me but I find it completely impossible to sift through it. The search is completely broken, there is no catalog worth going through. The only think worth looking at are the lists curated by Apple but then again usually I'm looking for something more specific.

In practice the only reliable way to find a good App, is going to be searching with Google, reading reviews outside of the App Store and eventually following a direct link to the App.

It's incomprehensible to me how anyone not just a normal customer would out of their own free will sift through this virtual garbage can. Many of the apps you'll see in search are so obviously scammy and questionable looking, you'll even get the disgust you'd get from sifting through actual garbage.

DasIch··on Scientists Find Brain Hormone That Triggers Fat Burning
Progress in medicine is very slow and that's concerning but it's not true at all that nothing has changed over that timeframe. Medication that cures Hepatitis C has become available in that timeframe for example.
DasIch··on Why I don't believe in Uber's Success
Amazon's endgame is to become the retailer, the only one.
DasIch··on Paper Centrifuge
You mean why haven't we achieved world peace and provided the entire world with stable electricity and sufficient capital to build labs and expensive medical equipment to fill them?
DasIch··on Ask HN: Will we ever have affordable and attractive urban housing for all?
Housing is partly a status symbol and those that can afford it often put measures in place to make sure that those they don't want to have living next to them can't afford to. Housing that is affordable for all, will by definition not be attractive for all. You imply the existence of a goal that doesn't actually exist and for which there is no consensus.

Even if that were a goal, you couldn't reach it because there is only so much space. This would be a problem even, if we were to use what space is available, which is usually not the case for political reasons.

Improved technology won't help you and even changing politics wouldn't get you to this.

DasIch··on Norway’s new passport – already a design classic?
Your from a country in which privacy isn't particularly valued I take it? I think you're heavily overestimating how much data is available to governments.
DasIch··on The science of Westworld
One can imagine that. I can also imagine that it would involve a lot of effort to create it, that it would be a lot of effort to use and that it would still be very limiting for all the reasons you mention.

Currently you can't even really walk around in a room without being incredibly restricted in terms of room layout, furniture and let's not forget you the headset with cables attached.

Last but not least even this hypothetical virtual reality is still just that: virtual. Simply the knowledge that something is merely virtual will always be somewhat of a disappointment, the same way a copy, no matter how perfect, is not quite as appealing as the original.

The concept of Westworld has an authenticity to it, that virtual reality can never hope to reach. As humans we are just weird that way.

DasIch··on The science of Westworld
I'm doubtful something like very good VR or even good VR can even exist. You'd need to simulate physical forces interacting on the human body and movement to make that happen.

Unless we achieve the ability to essentially run a MITM attack on the brain, to intercept commands from the brain and to provide it with sensory input, VR won't come close to being something genuinely deserving the name virtual reality.

DasIch··on Up to a third of Airbnb's price gap with hotels is due to tax treatment
I can have both because there is no relationship between profitability and competitive prices. Profitability doesn't imply competitive prices and competitive prices don't imply profitability.

That Uber happens to be profitable and offer competitive prices doesn't imply anything for their prices in the future.
