Quite some years ago there was some data backed evidence of this I would say. https://www.dkriesel.com/blog/2019/1229_video_und_folien_mei...

Here is the link to his talk directly https://youtu.be/0rb9CfOvojk?si=7EImZU9x4zFb6LSf

Its true that the network is quite dense and used by also cargo trains, but there is no denying that things got worse and worse. I constantly experience delay to do some stuff not working. I forgot even the minute threshold when a train is still punctual according to DB. I believe it's 10min by now, which can be deadly if you need to switch trains :)

There was one day the bus was late so I drove in with a grad student who did density functional theory calculations of MOFs and asked him "How do you make a MOF?" and he said "Beats me, I'm a theorist" so I figured that I wanted a quick answer to that one myself and it turned out to be "mix up the ingredients and bake them in the oven"

Turnover could also be seen as an addressable problem. "People are dying because of poor staff retention and rotation practices" this could be studied and improved upon.

A novel mechanism would be for a patient suing a hospital for malpractice for failing to retain nursing staff which it seems could be proven to be linked to worse outcomes. And when it comes to it, liability lawsuits are an adequate last resort to push back against hospitals cutting corners with staffing levels and staff pay when it comes to nurses.

What's up with train services reliability in Europe? In my european corner here, I always have to give this advice to people who are new to the city: do NOT use the commute train ever if the deadline is serious and absolute (you got a work interview, a flight, a funeral). Trains get stopped in the middle of the trip, get delayed, or get cancelled all the time!

The solution is to lose even more of your time (as if public transport wasn't slow enough already) and be at the station already for the previous schedule of what you'd ideally need to take. But at that point, sometimes it's just better to go a longer route by subway, or if traffic is not bad, go ahead by car for those occasions.

As an author, this sounds amazing, if I can also get a look at the things people ask.

Especially if I can get some sort of stats on the questions.

Like, if there were a lot of questions about when a character did something, then I know I wrote that badly.

Or if people talk about a set of characters, then I know that those characters made an impact.

Or if no-one asks about the book itself, but about some plot point or worldbuilding idea.

In general, if I, the author, can get a peek at this data too, it would be of immense value to me (and my publisher).

Because anti-tivoization doesn’t make sense in a software license.

Imagine you make a smart toaster, and you make it entirely out of open source software. You release all the changes you made too, complying fully with the spirit of open source. People could take your software, buy some parts and make their own OSS toasters, everything’s great.

But for safety reasons, since the software controls when the toaster pops, you decide to check at boot time that the software hasn’t been modified. You could take the engineering effort to split the software into parts so that only the “pop on this heat level” part is locked down, but maybe you’re lazy, so you just check the signature of the whole thing.

This would be a gpl3 tivoization violation even though the whole thing is open source. You did everything right on the software end, it just so happens that the hardware you made doesn’t support modifying the software. Why is that a violation of a software license?

This is what makes no sense to Linus, and TBH it makes no sense to me either. Would the toaster be a better product if you could change the software? Of course. But it seems to be an extreme overreach for the FSF to use their license (and that “or any later version” backdoor clause) to start pushing their views on the hardware world.

The old nuclear plants should definitely be inspected and safety issues should be remediated.

I have found this page on nuclear waste to be informative https://world-nuclear.org/nuclear-essentials/what-is-nuclear...

Some points: - The generation of electricity from a typical 1,000-megawatt nuclear power station, which would supply the needs of more than a million people, produces only three cubic metres of vitrified high-level waste per year, if the used fuel is recycled. In comparison, a 1,000-megawatt coal-fired power station produces approximately 300,000 tonnes of ash and more than 6 million tonnes of carbon dioxide, every year.

Important condition being "if the used fuel is recycled".

To quote from the article on recycling:

"Although some countries, most notably the USA, treat used nuclear fuel as waste, most of the material in used fuel can be recycled. Approximately 97% – the vast majority (~94%) being uranium – of it could be used as fuel in certain types of reactor. Recycling has, to date, mostly been focused on the extraction of plutonium and uranium, as these elements can be reused in conventional reactors. This separated plutonium and uranium can subsequently be mixed with fresh uranium and made into new fuel rods.

Countries such as France, Japan, Germany, Belgium and Russia have all used plutonium recycling to generate electricity, whilst also reducing the radiological footprint of their waste. Some of the by-products (approximately 4%), mainly the fission products, will still require disposal in a repository and are immobilized by mixing them with glass, through a process called vitrification."

There are various informative videos on Youtube that cover vitrification, where the remaining waste is melted with glass-forming materials at a high temperature, and the resulting matter can be safely stored in steel vats. In comparison to carbon from coal, the volume is miniscule.

Yeah I know you cannot track all journeys. Deutschlandticket, BahnCard 100, and similar things will be invisible. You can track the ones booked through the app though, and with a high enough sample rate you should get sufficiently close to the truth, unless there is a bias I haven't thought of yet.

You could also select random virtual journeys, I suppose. In arbitrary units you should at least be able to measure whether DB is improving or not. You could even delegate this to an independent organization. Actually, now that I think of it, isn't the API public? I'm reminded of the talk by D. Kriesel about DB data mining.

People had nearly a decade of experience with Donald Trump as a known political entity and decades of receipts and lawsuits prior to 2016 to speak to his amoral and corrupt nature. If they didn't know exactly what they were buying into they were idiots. He isn't exactly a master manipulator.

Also, The first time Trump was elected, the majority of voters went for Hillary Clinton. Second time, it was still 49% versus 48% for Kamala Harris. The majority of Americans have never voted for Donald Trump nor ever supported him.

Also for kids at least, sometimes they really will be happier with less choice. Sometimes kids make bad decisions and limiting choice to good options is helpful.

Additionally the inverse is true. Sometimes kids choices are restrained, and they really would like to do a thing they are not allowed to, and gift cards offered them away to do that. Case in point: my tween figured out that we don’t let him buy in game currency for any the games that we do let him play, however, when a relative gives him a gift card, we let him redeem it, making gift cards incredibly popular gifts.

Yes, dominance is preferred. Countries’ resources aren’t evenly distributed, and this fact determines foreign policy more than anything else.

There’s no world govt or global authority. Every country must look after its own interests.

Having every country cooperate requires trusting some entity as a global enforcer, one that wont abuse their unchecked power. Obviously, america has played this role since ww2 but not without plenty of mistakes and oversights.

We as humans haven’t found an alternative to this yet.

I think it’s a mistake to put even teen social media use in the same category as screens for young kids, and I suspect most problems are from the latter.

3 things should be studied: screens for kids (regardless of app), short-form video for teens, and non-short-form peer-group social media (what teens had from 2008-2015 or so). I bet we’ll see very different impacts from each.

I'd encourage people to look at the history of Fujifilm (the Japanese peer to Kodak) to see why they didn't fail, but Kodak did.

https://petapixel.com/why-kodak-died-and-fujifilm-thrived-a-...

TL;DR: Fujifilm diversified quickly, Kodak clung to the film business for far too long.

If you're an Otaku it's not too surprising you don't like Ghibli. Ghibli is quite atypical and the reason it got popular is because it's not like the standard anime, that people used to look down on, in the 80s and forward until maybe 2015 when it got normalized.

>The stories don’t really have a proper conclusion, it’s often a pattern of a thing happened, let’s undo the thing, life goes on.

One could say this about Ghost in the Shell, Akira, and even Evangelion too.

I personally think that Ghibli is popular because it gives a sense of nostalgia, a beautiful depiction of nature and it feels alive because the care that goes in to the background and background characters movement.

It feel less like a theater, a story crafted to entertain, and more just like a snapshot of life of someone/something that will go on after the movie ends.

Also as for music. If you watched the American version, they've actually changed many scenes and added additional music. Disney said that American populace couldn't watch a scene where no music is present for happens for more than 3 min so they had to add some extra music. [1]

My recent Sony TV does this.

But also I pretty much never use the TV button to turn it on, I click a button on one of the connected devices to wake it and the TV turns itself on with that input selected. Even if it’s already on, if I want to switch from one device to another I can just wake the other device and it will switch inputs for me. It works really well, I almost never have to use the input selector and it just does the right thing reliably.

External display reconnects kept breaking my workflow, so I built a small macOS app to save and restore window layouts reliably.

Also: keyboard shortcuts to move windows between displays (⌃⌘←→) and nudge them pixel by pixel (WASD).

Yep, it's just that the world is extremely competitive, and you are constantly forced to think about your “productivity.” If you are not hustling and generating some value, you are “wasting time.”

Of course, that's nonsense. You are living your life to do whatever you want with it, and if that's spending a lot of time on social media, you just need to be OK with that (as in, it is a conscious choice, not an addiction).

Sorry I was not aware of GAAP. Anyways, I think the primary benefit is the interest-free financing. The company gets to hold the customer's cash and use it for operations (working capital) for the entire time the gift card is unspent. Maybe I was not right with the account terminology and should have mentioned the cash flow positive impact only.

Maybe it is more accurate this way?

It seems like it was more complicated than that:

> He found refuge, at first, in family life. In his early 20s, while stationed in Belfast, he met a local woman and had a child with her, Adam. In 1995, though, the marriage crumbled while the Bushbys were living in Hampshire, England. Adam and his mother returned to war-torn Belfast, where Karl, as a British soldier, was forbidden to visit. He found himself “alone, wondering where my life was going.” He created for himself the ultimate challenge: a journey that would show his paratrooper mates he was no runt.

He didn't leave until 3 years after he'd already been separated from them.

I'm not saying it's good that he didn't try to have more of a relationship with his son, obviously not. But it seems like it was already a complicated and broken relationship with the mother, across countries. Going on his trip wasn't walking away from an otherwise functional family.

Screen time features exist on most devices. Parents - please set them up. It doesn’t take a lot of effort. I limit my kids for 1/2 hr of screen time per day. I exclude apps like iMessage, phone and maps.

Yeah - they do ask for more time here and there. But it’s pretty well controlled and they adjust to it

I thought, "That sounds like an interesting book." And then I read the precis on Wikipedia.

Humans. Everything has to be a fucking competition. Turned me right off reading it. This is one of the (many) things I hate about humans. Along with ideas that go in to the brain and get stuck there and have to be defended to the death without the brain ever having thought critically about them even once.

Why gatekeep? Why compete about things that don't need to be a competition? Why let yourself be brainwashed about a philosophy or a company or a person?

Humans. Yech. Barf. I hate humans. They make me sick.

The proven pipeline you are discussing here isn’t going anywhere. PhD students still will do their phds. What this kind of funding structure will do is reduce the amount of time writing proposals. It’s not dissimilar to Norways research centres for excellence which are funded for ten years. I think this is good. Like, I have three separate proposals I’m writing concurrently. It’s annoying and takes away from my ability to interact with my colleagues and those I advise as well as my own research. Additionally, it’s basically impossible to hire engineering type roles which are way better than trying to convince a postdoc to be a software developer. Additionally I see a lot of colleagues not optimising for impact where I feel that this program will force that.

It's not that simple.

In the email you have linked to, he does not support tivoization. He simply says that he finds the term offensive (which is really funny coming from him).

Torvalds has also publicly stated that he doesn't think that tivoization benefits users, but it's not his battle to fight. More info on that topic can be found in the linked YT (linked at the precise time he is answering the question about tivoization, but the whole video is about GPL v2 vs GPL v3).

That's always the case for through stations, I believe. However even terminus stations don't have their platforms locked to a fixed destination. Milan Central station has 24 platforms and each of them hosts multiple routes. Rome Termini has 32 platforms, same thing. You can monitor departures at this link, if you are very patient to keep track of them

https://iechub.rfi.it/ArriviPartenze/en/ArrivalsDepartures/M...

Of course usually the same train departs every time from the same platform. I think that it helps everybody.
Show HN: An early-warning system for SaaS churn (not another dashboard)
by Jide_Lambo | 2025-12-13 14:47:10+00:00
Most customer success tools tell you what already happened.

We built FirstDistro to answer a different question: Which high-value accounts are about to churn, before they tell you?

Instead of dashboards, it: - watches usage, engagement, and sentiment patterns across accounts - flags subtle risk early (even when accounts still look "health") - triggers alerts with clear next-best actions, not just scores

The insights that drove this: surprise churn usually isn't sudden, It's silent. We're working with lean CS teams where losing one $10k+ ARR customer really hurts.

Would love feedback from folks who've dealt with churn firsthand: - what signals do you wish you had earlier? - where do existing CS tools fall apart for you?

Happy to answer questions or share what didn't work along the way.

Regardless of what information the Texas AG thinks parents should have access to or why, it's always seemed to me to be a matter of time before the monopoly status of Epic would come up.

I generally have a positive view of the Obama presidency, but I think forcing healthcare systems into EHR systems on a certain timetable was a huge mistake. It led to huge cost overruns as systems were forced to spend money they wouldn't have otherwise, on a timescale they wouldn't have otherwise, and pushed them into adopting EHR systems that could be viable within that timeframe, rather than systems that might arise organically over time.

How exactly do we come to the conclusion that a system feels pain? Is it because it told us so?

In very cold weather, my car tells me the tires need air. The warning, like that of the time to change oil is bright yellow and flashes when I start the car. Is my car in pain? Is it unethical to drive my car when it is cold as I'm hurting it? Would the answer change if in addition to a warning light a voice were to say. "Your tires are low and it hurts me"?

In my opinion, we have no ethical obligation to any non-living system. I think we certainly have a stronger ethical duty of care with respect to the shared resources we consume than we do to any AI system powered by those resources.

LLMs, at least as they exist today, could be trained to be very good at producing text that looks like formal specifications, but there would be no way to guarantee that what they produced was a) correctly formed, or b) correctly specifying what was actually asked of them.

You might be able to get (a) better by requiring the LLM to feed its output through a solver and forcing it to redo anything that fails (this is where my knowledge of current LLMs kinda falls down), but (b) is still a fundamentally hard problem.

> Federal preemption requires federal law (aka laws written by congress). How else would it get to the supreme court?

1. No federal preemption currently. (No federal law, therefore no regulation on the matter that should preempt.)

2. State passes and enforces law regarding AI.

3. Trump directs Bondi to challenge the state law on nonsense grounds.

4. In the lawsuit, the state points out that there is no federal preemption; oh yeah, 10th Amendment; and that the administration's argument is nonsense.

5. The judge, say Eileen Cannon, invalidates the state law.

6. Circuit Court reverses.

7. Administration seeks and immediately gets a grant of certiorari — and the preemption matter is in the Supreme Court.

> passing new law … only way they'd get it in front of a judge.

The EO directs Bondi to investigate whether, and argue that, existing executive regulations (presumably on other topics) preempt state legislation.

Regardless, the EO makes it a priority to find and take advantage of some way to challenge and possibly invalidate state laws on the subject. This is a new take on preemption: creation of a state-law vacuum on the subject, through scorched-earth litigation (how Trumpian!), despite an utter absence of federal legislation on the matter.

It's not a local IPC exactly. The roundtrip benchmark stat is for a TCP server-client ping/pong call using a 2 KB payload; TCP is although on local loopback (127.0.0.1).

The payload is encoded using myra-codec FFM MemorySegment directly into a pre-registered buffer in io_uring SQE on the server. Similarly, on the client side CQE writes encoded payload directly into a client provided MemorySegment. The whole process saves a few SYSCALLs. Also, the above process is zero copy.

I create web games and wanted to record demos on my phone with a face cam overlay, similar to the ones you see on YouTube and TikTok gameplay videos. Unfortunately, I couldn’t find any app that did this effectively, so I decided to build my own, called Demo Scope. It’s an iOS app that includes a built-in browser. You can load any website, position a draggable and resizable face cam, and start recording. The app also displays touch indicators, allowing viewers to see what you’re tapping on the screen. Additionally, it supports RTMP streaming, so you can go live if you prefer. Free to download and use, $9.99 one-time purchase to remove watermark for life.

In the case of piling sand exactly in the centre, the intermediate states between the initial state and reaching the final equilibrium seem to get closer to having a circular boundary as the grid size increases, instead of the diamond-shaped boundary you might expect for a symmetrical object in a planar grid. Take a look at the largest resettable grid doing this within a couple seconds of being reset.
