Hi HN, author here. Glad you're enjoying it!

I put it together as a kind of Stoic practice to reflect on the fact that we will all die, but also with a data scientist hat on to try to get myself to think about life expectancy as a distribution, rather than an exact number.

Show HN: Schengen Zone Travel Day Calculator
I built a small tool to help people traveling to Europe keep track or calculate how many days they will be in the Schengen Zone countries and - assuming they are restricted by the "90 days in a 180-day window" - how many travel days they have used and have remaining.

It's not 100% but I used ChatGPT to help me get it functional in a few hours and it's been the first thing in months I've pushed live so it felt like a win.

Would love feedback from anyone that knows the Schengen Visa 90/180 limits on how I could improve it a bit as I will eventually build it into a larger Europe Travel App I have been building forever.

Things I still need to do:

1. Add Text describing the Schengen Visa requirements, limitis, and included countries.

2. Fix A couple edge cases where the calculation fails slightly.

3. Add a disclaimer that this is for planning purposes only and users should consult official docs/country channels

4. List of Nationalities/Passports that this specific tool actually is for

As someone who was part of the rollout of HTTP2 for a $large_website, I can confirm that "this will harm mobile performance" was outright and flatly rejected. This included people who were our reps on the w3c. I just had to sit there and wait for the real world metrics to come in

"multiplexing will remove bottlenecks!"

"benchmarks prove that its faster!"

"you just don't understand how TCP works"

"the people at google are very smart, what do you know?"

"server push will reduce latency"

etc etc etc.

We even had the graphs of page size over time (going ever up) and average usable bandwidth (not keeping up, especially on mobile) None of that mattered until the rollout had a real world effect on our performance.

Some things in [1] might provide answers. To be fair, from a cursory look at [2], many of the concerns from [1] appear to be addressed--or at least works in progress--in [2]. I also enjoyed [3] on this topic.

> To a very mild degrees, yes.

To a degree that young women are wildly more successful than men. They practically rocketed past them in just a few decades.

Don't pretend this is "mild" success. It detracts from your own argument by making it look like you're not arguing in good faith.
Bill Gates has probably had 51200 times more impact on the world than me or other more average people. Do you disagree about that? Maybe I could have had that level of impact given the same circumstances, but probably I wouldn't, most people with his circumstances didn't. And most likely I would have stopped working the moment I had enough money, I never would have gone on to push for more and more, expand for ever greater impact, I'd be happy as a millionaire like most other people would and stop growing.

People who continue working to expand their impact even when they don't need to are rare.

The latest Soyuz revision is ~$50m per launch, it has a payload less than half of a Falcon 9 that lands on a droneship, and ~2/3rd of a Falcon 9 that returns to launch site. Making it twice the cost per kg. The highest flight rate it has ever achieved has been 2/month. It has a 96% success rate.

The latest Falcon 9 revision is ~$67m per launch. Lately it flies every ~3 days. Over the past year it has flown ~100 times. It has a 99.4% launch success rate, and a 98% landing success rate.

Clearly this shows that the Russians are superior.
are there exceptions to this?
They might do one to test deployment, but it'd be a throwaway. Their relight test was skipped (not said why), so they still don't have confirmation they can control where Starship re-eneters. Until that happens, it's very unlikely they'll target actual orbital velocity. The Starlink satellites do have thrusters, but they're ion engines, so not nearly enough thrust to get that last bit into orbit before they'd re-enter.
It's a super common form of theft in the UK at the moment. Not sure exactly what equipment they are using but it's clearly consumer level.
It does sound like this means it's now easier to get a touch screen, embed a tap logger in it, and then swap someone else's screen with it. (Similarly, for the camera module, etc, etc.)

A better approach would be to force Apple to allow the device owner to pair parts (third party or not), and for Apple to provide a list of authorized non-OEM parts to anyone that was considering buying a used phone.

Also, I wonder what this does to the anti-theft mechanisms. Before touch id, basically nobody set screen passwords, and phones were stolen at extremely high rates. After that, and because a stolen iPhone is marked as such and won't work with Apple services, phone theft dropped to almost zero.

If Apple's not allowed to prevent the pairing of the stolen parts in Oregon, I'm guessing it will lead to a black market industry there, where people launder stolen phone parts into refurbished phones by mixing them with parts from broken phones.

It's a tradeoff, as you allude to at the end. Our house is a mid-1800s build. Thus it's safe to say that there's some survival bias at work and it was solid enough to persevere. There are things our friends with newer houses go through that we never experience. On other hand, we have our own issues. retrofitting modern benefits is difficult, at best.
So many more companies prefer hiring you all remote now, at the cost of local US remote workers

Happy for you all but again it’s come at the cost of local US remote workers… the chickens have come home to roost of the WFH movement
I've been wanting to do this exact thing for a couple months, not for any of what their talking about.

I ran a wiki for local music artists. I started it on an ancient version of mediawiki for use with an ancient extension that wasn't even used, so overall bad idea. It no longer works on a modern version of php so I'm having a lot of trouble getting it back up.

But on that same note, a federation of local wikis, like for small towns/cities, artists that sort of thing, I think would be very cool.
> This isn’t a disability, sociopathy is a self-propelled toxic character trait, typically resulting from deep childhood trauma that our society rewards structurally.

> Mostly we just need to identify and isolate people with ASPD as quickly as possible.

I find this interesting as it relates to the autism spectrum... there is pretty universal resistance to accommodating / understanding the difficulties people face. It seems like a really uphill battle to get people who benefit from their toxicity to voluntarily take a "more difficult" route than they otherwise can.

I suggest that we don't need to do anything with the APSD folks, what we need to do is normalize the idea that their behavior is abusive and support folks who are structurally disadvantaged via their behaviors.

If enough of regular society gets tired of their shit they will take corrective action... until their behavior "looks bad" to others they have no incentive to cooperate.
These are family members and/or in-laws, I'm not charging interest to them, so if you count inflation it's actually costing me money.

So it would absolutely be a second unpaid job, but I'll admit that I didn't specify why.
No. They aren't really interested in learning (yet?), and I don't force it.

I do show them the type of force-multiplying work I can accomplish and they seem mystified. But then they use Scratch in school and can't do the same kinds of things and they aren't yet understanding there's stepping stones to programming.
I'm guessing 33 Raptor engines won't feel the effect of whatever drag those fins might produce. Instead, they'll just drag that drag into space
There are plenty of things which can have meaningful regulation when it comes to AI. Here are a few:

- where legal liability is placed in the event of an automated system making a decision (consider competing companies using the same AI-product to set prices (RealPage), or customer support chat bots agreeing to a provide a remedy to a customer)
- considerations around training data containing PII
- IP ownership of output
- implications on the IP of input and derivative works (and, is the model itself a derivative work?)

Note, these topics aren’t too specific to the implementation or technology involved but instead pertain to the side effects of AI’s existence and use.
I did a short YouTube version of the announcement: https://www.youtube.com/watch?v=QuyBWDx21d0
While they point out some flaws in the guest permission granularity, did they actually exploit any flaws, to make it work? My understanding was no.
These comparisons feel like bad faith. This is what they actually said:

> I've always been a cautious skeptic of ADHD in children. On the one hand I know ADHD is a thing and that it legitimately affects some children ...

They explicitly say that they know it affects some children, but they're concerned that it's overdiagnosed because the symptoms have overlap with normal child development. This isn't some kind of uninformed conspiracy theory, it's a legitimate concern shared by experts in the field [0].

My fear isn't that experts get confused and mix up real ADHD with normal childhood, my fear is that parents expect too much of their kids and convince their family doctor (who isn't an expert) to diagnose the child and prescribe Adderall. That fear is totally compatible with ADHD also being a real thing that actually needs treatment in other children.

So interesting seeing this hit the front page while being sat in an auditorium in Barcelona at wasm i/o listening to one of the original creators of Krustlet, Taylor Thomas from Cosmonic, compare and contrast literally this 'wrapped in k8s' approach to the 'alongside k8s' interop alternative.

Great talk, highly recommend watching it on YouTube if you're into this kind of thing. No link but I imagine it'll be up pretty soon.
Yes. It would also need to be enormous and use the same type of supercooled receiver.
This is very useful. I'll definitely use it the next time I'm making a CLI.

Stated simply: zero-thrust "orbits" repeat the same trajectory again and again. So if you end your burn in the outer atmosphere near your launch pad, the next time around you will be back in the outer atmosphere (near where the the launch pad "was", ignoring the rotation of the planet). And since there's air there providing resistance, you'll re-enter and crash.

Getting to orbit requires at least one more burn near the apogee of the original orbit to circularize it and ensure the spacecraft doesn't approach the atmosphere again. Starship didn't do the apogee burn they intended to do, so didn't demonstrate this capability.
If someone has staked a claim over an article, regardless of its factual accuracy, it's almost impossible to fix problems. Look at any politicians, celebrities, topics that are contentious in the public sphere, and you'll find control over the topic has been taken. There is no sane recourse - you can find endless examples of years long discussions as people who know what they're talking about battle it out with empty headed wiki editors who simply want the clout, or don't know the first thing about rational discourse and insist on their weird, distorted views of reality.

Wikipedia could be made much less political, much more open, and given some mechanism by which consensus could be achieved without having to fight with tin pot tyrants in control of a wiki page.

Wikipedia mostly works, but there are parts of the tech and processes that are unnecessary, counterproductive, and fundamentally political.
Yeah could be. Some of the debris looked very specific in shape though. On some shots of starship you can see missing tiles (not many though)
Given that MV2 is apparently here to stay in Firefox, I really wish Mozilla would implement Chrome's backported runtime per-tab permission model in it as well.

At this point, I find it very hard to justify installing extensions requesting the install-time "all data on all sites" permissions, but many popular extensions don't seem to be willing to upgrade to MV3 due to the restrictions this goes with on Chrome, and supporting two targets is probably too much work.
Which Czech part, Bohemia, Moravia, Czech Silesia, or ...? Was it the "regions with German-speaking majority"?

Languages had everything to do with it. "Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German-speaking majority should be included in the Republic of German-Austria."
Non-reusable boosters don't go into orbit and perform calculated crash into ocean soon after launch.

Small second stages and spacecrafts can be allowed uncontrolled orbital reentries because they usually burn-up. Starship is too big for that, debris would rain like when Space Shuttle Columbia disintegrated over land. They most likely will need to show engine relight capability to control reentry point before going orbital.
The indigenous population is gradually increasing over time, which is a curious thing in a country whose leader who has confessed to presiding over an active genocide against them.

It would take many generations of this trend happening for the Indigenous to become big players, but also not THAT long, maybe a couple hundred years.
I can speak to this. Containers, and by extension k8s, break a well known security boundary that has existed for a very long time - whether you are using a real (hardware) server or a virtual machine on the cloud if you pop that instance/server generally speaking you only have access to that server. Yeh, you might find a db config with connection details if you landed on say a web app host but in general you still have to work to start popping the next N servers.

That's not the case when you are running in k8s and the last container breakout was just announced ~1 month ago: https://github.com/opencontainers/runc/security/advisories/G... .

At the end of the day it is simply not a security boundary. It can solve other problems but not security ones.
> We may not like the idea of people choosing different medical treatments than we'd choose, but that's their right. Even if it's a foolish behavior to reject modern science, they can choose foolishness.

The point I was trying to make is

1) the anti-vaxx discourse is spreading falsehood, the "violence against pedophiles" is not. The anti-vaxx is not just "opinion", is "demonstrably stupid opinion", while the second is "different moral than mine".

2) anti-vaxx will kill anti-vaxxer kids AND non-anti-vaxxer kids (because it will reenforce dangerous diseases). The anti-vaxx discourse is harming your innocent children, the "violence against pedophiles" will not harm innocent people (of course, you can imagine downward slide, but for sake of argument, let's say it's not the case here).

You say that you are ok if people have different opinions, which themselves have direct impacts on people, but then, you say you are not ok if people have different opinions, because they have direct impacts on people.

You have good point against the person having the "violence against pedophiles" opinion (and I agree with you that this opinion is not good), but you can build similar and exactly as valid arguments for the anti-vaxx one.

So, it looks like that your choice of "violence is more deserving of censorship" is just you having specific moral opinion of what is worst and what is better. But other opinions are as valid as yours. So it's a bit strange to talk about "free speech" and explaining that someone is just wrong because they don't have exactly the same morals as you.
> You know how good parenting looks like? Tons, gigatons of time,

While I agree, you just gave advice that is completely impractical to almost all of us. For most people driving the kids to school, doing all the tasks needed to get the money coming so that the bills can be paid, doing household chores and trying to share the tiny rest of the time between their[0] needs is already a success.

[0] That is, the kids, their partner, and themselves, each of these requiring something different.
If their cost per kg to orbit, with total loss of both Booster and Starship, is substantially lower than any of their competitors - then it is success, and recovery is just icing on their profit margins. Er, cake.

(And would be very cool marketing and PR, obviously. Not that SpaceX has much need for either of those.)
Factors are of course overlapping, but you could think about what questions a life insurer would ask you, since they have money on the line and probably the best models.

Smoking is a really big one, given that it's estimate that 2/3 of life-long smokers die due to smoking and that continuing to smoke across a lifetime is estimated to reduce your life expectancy by 10 years.

Coming from one of those countries where a lot of engineering gets offshored to, the best and brightest engineers in those countries DO have options (no, not just immigrating to a rich country) and won't be a code monkey for multinationals.

I have been to IBM offices in São Paulo a few times and let me just say, although they paid reasonably okay salaries it wasn't the first choice of work for most engineers...

And that is on top of the problems you are describing.
Bullshit. This isn't "conservative politics". This is right-wing hate behind the thinnest veil of "political entertainment".

They don't really talk about small government or fiscal conservatism anymore. They talk about the "threat" that is posed by LGBTQ+ people and immigrants.

I can't even talk to my own father anymore without him getting angry. Angry about nothing. That's one of millions of very real relationships that have been very directly damaged by Fox News. They don't get to do that, then just shrug it off as it it's an accident, and not their primary business model.

If so that would be amazing.
I know a lot of wealthy people, none of them are stupid. They aren't geniuses but none of them had issues in college. I know a lot of poor people from military, a lot of them are stupid and struggled with the very easy material you have to learn in the military.

And this is what statistics tells us, rich people are very rarely stupid, quite a lot of poor people are. The world isn't fair, but stupidity is such a massive drawback that it is basically impossible to get rich if you have it. Stupid people get tricked in deals everywhere etc, there is just no way for them to reach anywhere without extreme amounts of support.
Fully concur and I think you describe better what I mean by isolate

The idea of isolating those people is that we actively reject abusive narcissistic behavior with no qualifications. That means it’s a one strike you’re out rule socially for toxic behavior

I truly wish that teams used retrospectives in this manner instead of the shallow conversations that are often devoid of blame. Not that every sprint needs to have a deep, impactful retro, but it's nice to talk about shortcomings, be able to accept blame, and move forward with actionable items. Everyone comes out ahead.

First thing that comes to mind: Starship has a lot of protection against burning up, so huge chunks of it could survive and cause damage.
I worked on one of the first dual core processors when I was at C-Cube Microsystems way back in 2000. It was an SoC with two microSPARC cores. One core was a general purpose processor for system functions running VxWorks and the other core was an MPEG-2 encoder/decoder running bare metal.

There was no MMU and the direct mapped data caches were not coherent (data segments had to be padded to a cache line to avoid the processors overwriting each others memory).

The chip was designed by Les Kohn of i860 fame. Here's a pic of an engineering sample with a 2001 date code.

The loss of sanity I reckon was when they found out about all the backdoors and lax security the old system had. Incrementing int for id's, the session key being part of the url as a parameter, the XML. This may be something you're ok with but for those of us who care about security, this would drive me mad as well.
I would agree, except it is not some random average guy in a vehicle.

This was a concern citizen, who was a whistleblower against his employer, who had just begun a legal deposition, and there are billions of dollars at stake.

So - the scenario possibly just isn't that simple.

> do people really believe the unemployment rates....

When the government measures what it calls the unemployment rate, you might wish that it were measuring what you call the unemployment rate, vs. what it calls the unemployment rate.

But at least the government's definition of the unemployment rate hasn't changed, and each time they measure it they are measuring the same thing.

So, even if you doubt the absolute number, you can still have confidence that if you can compare the current number with past numbers, you will get a reliable reading on whether things are moving in the right direction or not.

AS I said, high-tech is not used to facing this--it was us who were automating thing, and letting businesses do more with fewer people. Now its finally come around to us, and it sucks, but its nothing everybody else hasn't faced since the beginning of the industrial age.

Why Cross-Examination Is So Damn Great
Zinsser's Writing to Learn disappointed me. I agree with the premise of the title, and have had many of those "Eureka!" moments when writing out a problem, but the book doesn't really make the case that writing helps to learn nor does it give a guide on how to learn by writing. Rather, it is an encomium to the value of good writing about technical topics for the lay-folk.
