>for the vast majority we already get plenty of vitamin C

This is highly dependent on the population you're talking about. There are plenty of people around the world who don't have great nutrition and don't eat large amounts of fortified industrial food.

>for the rest of us massive doses just make our pee more expensive

The study I linked reported ridiculous doses of vitamin C "dramatically improved the clinical state and cardiovascular, pulmonary, hepatic and renal function" in ICU spesis patients. Like 200-400 grams of sodium ascorbate administered over 7 hours. The recommended daily nutritional consumption of vitamin C is around 80 milligrams.

There are other studies reporting other positive outcomes for large doses of vitamin C. This isn't a recommendation that you should take hundreds of grams every day yourself, but there is ample evidence in a clinical setting for "immune boosting" vitamin C in large doses. (and also criticisms of the daily value for being too low)

sort -V works the same way (1.10 > 1.9 > 1.1), as does every package manager I've ever used. Using floats for version numbers is just as insane as using them for financial transactions, but that's classic Perl for you (bonkers in their own unique way, with an optional sane system that exists in parallel which then lets you create even more bugs by confusing them).

Where I live, there are about a dozen new housing development sites. I pass by 3 of them on my way into work, and my drive is only 10 minutes long. I've lived here 15 years and haven't seen anything like it. Someone somewhere must think it's worthwhile.

Disclaimer: I don't live in a major city, I live just outside a minor one. It's all condos.

@tlocke

But that isn't a mathematical expression. At best, it would appear to be energy * maximum_Carnot_efficiency (for heat engines anyway)

But it seems not to be adding very much, since Carnot efficiency depends on delta_(T). The OPs point that exergy doesn't depend on T is tautological since T has already been accounted for by the Carnot expression.

So far as Laokoon goes this weekend I went to a track meet [1] and took pictures of people throwing the discus for the first time. I made plenty of images that were evocative of Greek sculpture but I think that's because Greek sculpture was motivated by athleticism. (Unfortunately the protective net made all of these images confusing)

If you take an average frame out of a sports game you don't see a clear story -- in basketball, for instance, you can catch the ball leaving the hands of the player or you can get the ball going into the hoop, it's not so easy to make a picture that unambiguously tells the story that № 15 scored a basket.

One answer to that is give up and say "a good portrait is a good sports photo" and that works, the other is to catch a special moment from a special angle like this shot [2] where for just a moment the ball kicked up a plume of dirt so you know the batter bounced the ball right in front of himself and the presence of a runner on third base adds to the tension. Nothing distorted there at all!

Show HN: Stravu – Editable AI text, tables, diagrams (also multi-player AI)
by wek | 2025-07-21 13:33:54+00:00
Hi HN! I'm Karl one of the co-founders of Stravu. (https://stravu.com) Using AI for work 24x7, we realized that four things would make AI more useful for us and a lot of other power users and teams:

Editable AI: AI gives output that is half right and our only option was to either keep chatting laboriously or copy it to a Google Doc. We made Stravu so you can edit the AI text, tables, diagrams in chat or in an attached notebook.

Approve AI changes: When AI makes a change to some text, you can't tell what changes. We put Red/Green diffs that you can approve into Stravu.

Unify text, tables, diagrams: We were jumping between tools to work with AI on text, tables, diagrams, etc.. Just because Microsoft did that 30 years ago, doesn't mean it makes sense now. We made Stravu so you can work with AI across text, tables, diagrams, (and 2x2s, formulas, more soon) and have them inform each other.

Actual multi-player team collaboration with AI: We couldn't collaborate as a team in AI (even with the ChatGPT Teams plan). We wanted to be able to chat with AI together as a team or see the changes AI was making in the canvas/notebook together and edit together. So we made Stravu support multi-player collaboration in every aspect... chats, notebooks, text, tables, diagrams..etc.

Some of the use cases of our current Beta customers include: scrum teams doing feature/customer/competitive research and feature definition, account teams building vertical/geo/account plans, consultants and investment teams working on market/company analysis.

We are currently in beta and actively iterating based on user feedback. Please try it out at: https://stravu.com We highly value your feedback!

This is not true for at least me.

Let's say, I am making something concrete by putting ideas, thoughts, knowledge into paper. While doing it, I am finding gaps and mistakes and finding opportunities to correct them. But it is not limited to 'correction', it also opens newer dimensions and perspectives- ones that previously didn't exist in my conscious mind.

I consider writing as a tool of thinking. Another tool is brainstorming with a group, or any group discussion in general. These amend to your thoughts, make the existing ones more solid, and opens new direction, and unravels connections previously not accessible.

Read this essay by Paul Graham: Putting Ideas into Words [0]. And also refer to his other essays on writing.

There is also a great book by Paul Zissner: Writing to Learn. I suggest this book to people.

Writing, when done while learning works akin to teaching- one of the most crucial steps in so-called Feynman Technique of learning.

I was surprised to have to scroll this far to see someone bring up that the comparison point seems to be Python... I mean, I have absolutely no difficulty believing the statement

> For every time I experience a bug in Python that would have been prevented in Rust by its borrowchecker, I experience maybe twenty borrowchecker issues.

Now, if you replace "Python" with C or C++, my guess is the ratio at _least_ equalizes if not flips entirely

I'm willing to forgive all these format's sins simply because I spent so much time in the eighties and early nineties dealing with all the retched and poorly documented bespoke formats people came up with before these existed. It was a breath of fresh air to be able to tell customers their XML file doesn't validate hence it is their problem not mine.

It's why some much money ( doubious sources or clean ) ends up in places like London.

Often it's looted ( or comes from exploitation ) from unstable countries where the weak rule of law has allowed the looting ( corruption or whatever ), and then moved to London to ensure nobody can then steal it back directly or via political revolution.

Taxes are the price of civilisation - if you want the good life - you have to help support civilisation - not free load.

What software do you use that follows this convention? I can't think of any (as a trivial example, Linux 3.10 and 3.11 were released several years after 3.1, and after Linux 3.9).

Every package manager I've ever used works the same way too. For projects that use SemVer, this is even explicitly standardised.

>EndeavourOS and CachyOS don't put any barriers upon the user, what fixes and guides that work for Arch will work for them

The Arch project itself disagrees with that, they will not provide any support or make any assurances about what works on other Arch based distros. The edges being filed of is a substantial difference, which sometimes will matter. The distros (by design) include a lot of defaults, which are assumptions Arch does not make and which it assumes users know about.

>SteamOS also clearly has a place as an immutable Arch, hard to argue that it's been a disappointment or a cause of frustration for users, given the narrative has been an overwhelming want from the gaming community for a desktop version. I guess the frustration comes from, if anything, it's narrow scope.

I specifically talked about managing Arch yourself. On the Steamdeck you never have to touch a console to make things work. Valve will provide updates for you, no manual intervention needed. It is also well defined and extensively tested hardware, which does not apply to anything else. No user should use SteamOS outside of the Steamdeck, Valve is clear about that.

Besides my main point still stands. If you can not install Arch, you lack basic Linux literacy. The moment your Arch based distro based, you can not fix it without these basic skills. You will be disappointed and frustrated and unless you are willing to spend a lot of time learning (after which you could just install Arch anyways) you will never touch Linux again.

> For example, to increase the appeal of electric vehicles - they hired German industrial designers from European automakers.

People always state this as if it's a gotcha, but there's almost zero large western companies that don't have Chinese people or companies in the loop somehow, whether manufacturing, materials, or even just everything except branding.

We live in a globalised economy. I bet if someone was setting up a very large plastic manufacturing plant in Germany, there's a very high chance they'd hire Chinese experts to help set it up, or even to run it outright.

> Hunger worldwide has been getting worse for the last quarter century or so.

That doesn't appear to be true. E.g., following links from the WHO page you cite gets me to https://openknowledge.fao.org/server/api/core/bitstreams/39d... ...

where Figure 1 shows hunger consistently decreasing from the start of the graph in 2005 to somewhere around 2014, at which point it plateaus for a while and then starts increasing somewhere around 2019-2020.

My recollection is that by 2005 where that graph begins, hunger had been consistently decreasing for quite some time, but a bit of googling hasn't found anything that quite answers that question. I did find https://www.jstor.org/stable/40572886 (looking at data from 1930 to 1990) whose publicly-accessible abstract says that "the proportion undernourished has been in decline since the 1960s and that the absolute number has also declined in recent years".

So I think the truth is not "hunger has been getting worse for the last quarter century or so" but something more like "10 years ago, hunger had been improving for about half a century; the improvement stalled for about 5 years and over about the last five years it has been getting worse".

(Which is still bad news, as far as the present state of things is concerned, but a rather different sort of bad news.)

No need to be worried about that. French law (like most others I presume?) is all about intent.

e.g. to be convicted of trespassing, it has to be proven you knew you were trespassing, or at least that you reasonably should have known.

So no, you wouldn't be convicted because you accidentally took down your own system, etc.

At the end of the day, regardless of whether the letter of the law will allow it or not, what is clearly being investigated here, is a supposed (and somewhat documented) intent at influencing the French people through a distortion of the Twitter/X algorithm.

Until now, all the "social media" platforms have essentially been regulated like hosting services, under the assumption that they have a fairly neutral stance toward the content they host. Hence they're not directly held responsible for what they display.

But if it turns out their algorithms aren't so neutral, it begs the question of whether they should be regulated like legacy medias, hence be held responsible for what they publish.

At peak season every year, O’Leary says something crazy like they are going to charge for the bathroom, or charge fat people extra, or get rid of arm rests, or have standing room only. The tabloids run the story and include a generous amount of quotes from O’Leary about how great Ryanair is. It’s very, very obvious advertising. The tabloids go along with it because it makes people angry, which drives traffic.
by chippiewill | 2025-07-21 13:36:46+00:00
They do slow it down from the passenger perspective, but Ryanair optimise for the overall cost of turning planes around.

Loading and unloading bags from the hold costs time and money. Transporting those bags from bag-drop to the plane means paying the airport for that privilege. Misplaced bags etc. adds a customer service overhead.

Ryanair deliberately don't use jet bridges so they can load/unload from both ends using built-in stairs

This is what I’ve been thinking about recently.

Babysitting one process, but giving it all of my attention[1] can lead to rapid progress.

Pushing forward multiple efforts simultaneously can lead to rapid progress if code is largely unrelated and you keep a sharp eye on branching and commits.

However, it’s remarkably easy to make a mistake and be enamored by how well the AI can use git to fix your mistake.

But the cost ends up being adherence to it, specification or architecture, or being distracted into scope creep.

The new scope might be useful for factoring, but that is also the kind of thing that interfere with your Main processor trying to handle.

And it’s remarkably easy to get lost in the state when you have to manage validation well.

The more mature the project and more intense the expectation of scm hygiene, the more punitive small mistakes can become.

It is not really a problem in my process prior to Claude code, which was almost entirely turned based chat.

I still have configured fairly complex and detailed session workflows to preserve state amidst the regular threat of auto compact.

Even I even have documentation, describing a plan to migrate into git worktrees myself, but haven’t been able to justify the move, as I continue to learn to be productive with a single main session focus.

[1] I don’t know if there is such a thing as constant focus on a complex genetic programming effort because of the delays involved. You can stare at the funny verbs anthropic picks while the tokens go brrrr for only so long.

There’s no such thing as “demand” in housing.

Only supply.

Housing has its own economics in which supply is the only solution ever put forward.

Not a single politician or economist ever says that most dreaded and awful word “demand”.

Property developers, politicians, economists, demographers, real estate agents, landlords all agree that supply supply supply will …….. errrr it will…… ummmmmm more supply will definitely……. something.

The problem is that housing is a major investment vehicle, people in these cities always complain about what's going to happen to their property values so they prefer exclusionary zoning.

Developers have a hell of a time building in these areas even once they get zoning variances, because abutters will show up and complain about every single detail and try to make the property as small and unprofitable as possible. You start off with a 12 unit building with no parking and you end up with a 6 unit building with 12 parking spots in a garage that no one uses.

There's one instance in my neighborhood where the city and developer have been meeting with residents over the course of a year to try and come to an agreement on what should be built. There's just a derelict single-family house on the lot.

> Where have we seen anything close to 'build more'? Regulations in many major cities have prevented building more for decades and I haven't seen any loosening of these regulations (they were only increased during the Biden administration).

Housing prices are high everywhere, not just major cities.

Interestingly, in my state we have a lot of land for building houses if you drive to nearby cities. Some people uproot themselves and move 30-45 minutes away so they can have a much bigger, nicer, newer house. Most often when they start a family.

If you’re willing to move an hour away you can even get these big new houses for very affordable prices.

Many people don’t want that, though. They want to live in the city. So these big new houses remain cheap, while housing in the city remains expensive.

It seems like an easy solution would be to start knocking down houses in the city and building tall, dense buildings. Except that is happening, and the same people don’t want those either. Even condo complexes are having a hard time selling units.

What people here continue to want is the one thing that cannot be scaled: Full houses of their own that are in the city. No amount of demolishing buildings and building density will fix that, because it’s not what they want.

I was completely wrong in guessing that COVID and remote work would help housing prices by allowing people to move anywhere. Most of the people I knew who relocated due to remote work took the opportunity to move toward cities where their friends lived, not to cheaper areas.

I think we must continue to build, though. Eventually new cities and interesting locations will be bootstrapped. I think housing prices in popular areas will remain stubbornly high, though.

Most people don't understand the danger of MRI, myself included. I trust the people and follow their directions but I can't really visualize what it would be like to get caught with metal in a MRI magnetic field.

For quoting the article : « According to the US Food and Drug Administration, MRI machines have magnetic fields that will attract magnetic objects of all sizes - keys, mobile phones and even oxygen tanks - which "may cause damage to the scanner or injury to the patient or medical professionals if those objects become projectiles". » the choice of words from both the bbc and the FDA don't really convey the risks.

Anyway there are very surprising issues in what is described : why did the wife needed her husband's help to get help although it is the role of the technicians ? Why was the husband in a place where he was able to hear his wife and not being prepped for MRI ? Why was it possible for him to enter ? And why wasn't the technician able to stop him entering ?

The real, adjusted cost of air travel has gotten to be so low because RyanAir is willing to push conventional norms. You are not required to book a ticket with them. You are more than welcome to pay British Airways 2x the money to go to the same destination. Be very careful what you ask for when it comes to onerous regulation -- The EU is great at causing unintended side effects.
by victorbjorklund | 2025-07-21 13:38:36+00:00
This is just marketing. They always do this because they know that if they say "Oh, we might charge for bathroom, we might charge even more for oversized cabin bags" then they know that the majority who doesn't bring oversized cabin bags is gonna feel like "Wow, this really must be the most low-cost possible" and they perceive that the value is more because they think that they are getting a great deal and don't get me wrong I fly with Ryanair all the time I find it very good but it's kind of marketing stunts.

The problem can not be solved by trying to manage supply or demand. We must ban the concept of the landlord entirely.

https://www.theguardian.com/lifeandstyle/2024/mar/19/end-of-...

A landlord gets a loan from a bank to develop a residential property. That loan is paid by the tenants who live in that property. At the end of the day, the landlord owns the property. This is fundamentally unjust. If the tenant paid off the mortgage, they should own the property, or their portion of it.

Can you imagine this for anything else? Imagine I got a loan to buy a television. The television is yours in every sense but in the legal sense. It is in your home. You are the only person that uses it. Over time you pay me back the cost of the TV, and some extra for interest. Yet, even after you have paid me back, you have to keep paying. It’s still my TV, and will be forever. If any month you don’t pay, I can come and take the TV away.

Another way of looking at it is that a residential development in a high demand area is basically a guaranteed money-fountain. Banks buy them and gift them to whoever they choose. They always choose people who are already wealthy and low-risk, causing an increase in wealth inequality. A bank could choose a homeless person instead for such a low risk project.

Another idea is to only allow renting when it is rent-to-own. A developer may build a large development, but over time that development will eventually become a co-op.

Remove profit motive from housing entirely. When the only interest someone has in a home is living in it, prices will make sense.

This doesn't track to me. People have been irrationally afraid of things since the dawn of time, based purely on hearsay (see religion). And surely even the simplest of language serves to warn about unseen dangers.

Entering the MRI room myself I was very familiar with the dangers of bringing metal inside, to the point where I would second guess myself and my own body. "What if my leg bone actually has metal in it for some reason?!"

‘Advocates say tokenization is the next leap forward in crypto and can help break down walls that have advantaged the wealthy and make trading cheaper, more transparent and more accessible for everyday investors. But critics say tokenization threatens to undermine a century’s worth of securities law and investor protections that have made the U.S. financial system the envy of the world’. The problem with securities laws is that they are complex, and even defining what is a security is a hotly debated question, esp in crypto. I believe back in 2021, Binance had to pull back their offerings tokenized securities bc of german regulators, so its a very opaque environment.

Is this real? K8s2.io just points to kubernetes.io.

And as much as people hate yaml, and I don’t blame them, language-based over data-based are always overweight abstractions, (and I say this as someone who at least aesthetically prefers language-based abstractions). I loved writing puppet, but navigating the language and its ecosystem itself seemed like half the job.

So this either feels like a fake demo, or a wrapper to kubectl
