There are also other harmful side effects of fluoride, such as fluorosis, which I have. It’s not a huge deal, and I personally still think it’s a huge net positive, but people should be allowed to make their own decisions, and the science is far less settled than you claim, and not comparable at all to the debate over climate change.

You may want to review the article linked from within the story. The original motivation here is not just to defeat the typechecker.

But it is?

>> "It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ"

Yes you would need a higher powered study to rule out the potentially smaller effect, but when your treatment can affect tens of millions of children, it doesn't seem crazy to ask for more funding.
Show HN: Standardising 'Unit Tests' for Prompts
PromptRepository is an open-source framework (Typescript) that illustrates an approach to creating more reliable LLM-based applications through systematic prompt validation, and testing.

Key features:

- Simple JSON schema for externalized prompts with versioning and parameter validation

- Lightweight approach inspired by Anthropic's guidance to "keep it simple" with LLM applications

- 'Unit tests for Prompts' inspired by Chris Benson/Practical AI's recommendations from episode 295.

- Bundled prompts to generate unit tests and evaluations for new prompts built with the framework.

The framework demonstrates a novel approach: bundle tested prompts with a framework that generate code to use the framework.

Repo: https://github.com/jonverrier/PromptRespository

Take a look.
Then let the AI first complete the documentation by looking at the existing documentation, querying the DB (with pg-mcp), etc.

Do human reviewing and correcting of the updated documentation. Then ensure that the AI knows that the documentation might still contain errors and ask it to do the 'actual' work.
Some people would prefer there to be fluoride added to the water and some people would prefer there not to be. There's one set of pipes (in a given municipality), so you can't please everyone. You might as well complain that the government doesn't offer you a choice of voltage or frequency for your electrical supply.

Looking around the thread, the idea seems to be that there is some kind of important metaphysical distinction between the government "adding" something to the water that people could in principle add themselves or merely "filtering out" bad stuff like pathogens — and that this metaphysical distinction is somehow linked to the difference between positive and negative liberties. As an aside, I think this probably makes no sense on a chemical level, as you generally can't remove stuff without also adding something else. But in any case, this strikes me as a uniquely American perspective. I think a more common perspective is the following:

* Essentially no-one wants raw untreated water supplied to their homes.

* The local government therefore needs to decide in which ways the water is going to be treated.

* This has to involve some compromises (because there's one set of pipes).

* These compromises are boring practical issues of municipal infrastructure and have no interesting philosophical or political implications.
My sense is that this was written with an in-person team that in mind. For remote teams, daily standups are also a way to “sit together” like the author suggests.
Ask HN: Any decent open-source CGM software?
I have some experience with Nutrisense Continuous Glucose Monitors (CGM) , and the experience is very user-friendly through the app. The problem is it costs $225/mo, and most of that cost is in the software.

I think you can get Libre CGMs for $40/mo but they don't come with any software or insights.

There has to be an open source solution, right? On google I saw a few people built their own projects, but I'm wondering if anyone here is familiar with the range of open source in this area and what the best app is.

I think management is just prone to wanting to believe the grass is greener on the other side. If you are already a cloud org with negotiated pricing and cost-optimization management would ask about building a data center and you would show them how much you would need to expand your IT staff in order to acquire the skills to operate the new data center never mind the upfront cost.
the better argument is there is little to no opportunity for interesting, curious, engaging conversations around topics like this. the people most likely to engage and be the loudest are people who aren't interested in being open to new facts and changing their opinion or having nuanced views. this leads to boring, hostile, us-vs-them political takes that don't have any substance.

They are just far far from mature. Your best bet for rust gui is still Qt bindings.
You're close but still a bit strawmanny. If we want poor kids to have better dental outcomes we should do more than just flouridate. We should find out why the poor have worse dental outcomes and address the root problem(s), which I would imagine in the US is something like soda consumption or lack of dentists in poor areas.
There was a thread the other day about Forth on 6051, and someone challenged Forth's utility. I think it fits the same niche: enables quick iteration, exploration, while maintaining a "just right" level of abstraction over the bare metal.

I don't think I ever took any lecture notes at all in the entirety of my CS education at Carnegie Mellon, long before COVID. Everything the professors taught was in slides that were published online, or in the best cases, full fledged PDF lecture notes that explained everything in detail and were published online.

This makes it significantly easier to pay attention during lectures. Denying your students work that you have already done is ridiculous. Whether or not a student wants your lecture notes is orthogonal to whether they come to lecture.
The conclusion from the largest and strongest studyies is that there is a certain level of fluoride that harms IQ: https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/....

"The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children"

They found fluoride in drinking water concentrations was associated with lower IQ, the opposite of your claim of "proven safe".

Show us some evidence that is proven safe, so far as I can tell all evidence points to unsafe or "we're not sure".

Yes, he will tariff up everything. But after a while, the average Joe will understand what the word "tariff" means. And then Joe won't be happy and the midterm elections will come.

Depends on what you consider "a lot", I guess. The article that this discussion is talking about apparently thinks there are enough to make its proposal for "converting Linux to Windows" worth an effort.
Well ya I don't say I condone, I'm very much an individualist (to a fault).

But also, we don't exist in isolation, and there are reasons societies evolve as they do. There has to be some level of social control and belief in being watched over at all times was probably pretty handy for emperors and to some extent those who would be victimized. At least back when it worked wide scale.

Scala is a lot more like lisp in this way (or actually, the C++ comparison is the much better one) than it is like go.

There are lots of ways to write Scala, to its detriment.

This isn't meant as a knock on Scala! It's a great language and in particular I think it's been influential on other newer languages. It's just that it does have this "multiple dialects" issue.

>You took an absurd comparison of a tried and tested naturally occurring substance

It's ironic that you assert this, and then go on to claim that I'm ignorant, when you seem to be the ignorant one. Penicillin was originally derived from a mold and is one of the popular antibiotics out there, so it's arguably "tried and tested naturally occurring". The same is true of lithium. https://en.wikipedia.org/wiki/Lithium_(medication)

We don’t even need the choking hazard of coins to justify getting rid of them.

There is essentially nothing you can buy that is individually less than a quarter in value, and probably still not a whole lot that is less than a dollar.

Maybe some disposable shopping bags? Some screws at the hardware store?

I think the US could eliminate coins and start printing 25 cent or maybe 50 cent bills, or perhaps not even do that at all. Transactions under a dollar could be rounded up or be made electronically (eliminate the minimum flat fee part of card transactions first, though).
True to a first approximation. A good second one is that a carefully enunciated [ɑ] isn’t correct, either; a schwa [ə] will sound better, so the vowels and the overall rhythm will be similar to the English word bazaar in a non-rhotic accent. Finally, the hard reality[1] is that all of this is heavily accent-dependent: in Vologda (500km from Moscow) you will hear [o] for the first vowel; in Ryazan (200km from Moscow) you can hear [a] ~ [æ]; even in Moscow itself, a radio announcer will say a fairly careful [ɐ] while someone who grew up in the poorer suburbs will have an almost-inaudible [ə] (this is a strong class marker).

The English word Moscow, meanwhile, is itself very interesting: it’s not actually a derivative of the Russian Москва, but rather a cognate, as both of them are derived[2] from different cases (accusative vs. locative or genitive) of the original Old East Slavic (aka Old Russian, aka Old Ukrainian, etc.) name.

No, that's not meaningless, I've tracked my time and turned out I've spent much more time than I thought on one website that only made me angry, I've blocked it and saved myself hour a day and don't miss the website at all. So yeah, from my experience tracking can be very useful and meaningful.

AppImages have a few problems. Ever seen how much dependencies you need installed to execute an AppImage?

You also need to be in an environment where you can create FUSE filesystems. And iirc the reference implementation requires the deprecates fuse2 library to work.

Snaps, Flatpaks, AppImages and static linking are all solutions to a real problem. But I don't think AppImages are an especially good solution.

I talked a bit with Richard Brown about supporting AppImages in Aeon, the OpenSUSE immutable distro. But he believed the base system would need far too much dependencies specifically to support the AppImage runtime including deprecated fuse2 support.
So how does this guarantee that it will never raise some libc error, or similar? Unfortunately I have become sceptical about "self contained" distribution methods.
By just looking at the video, you can see that they cut the engines after the rocket starts tilting. I guess that’s the flight termination system. Also, it didn't fall into the ground, but into the water.
If there were issues, they’d appear at population level studies. Lots of people boil coffee, tea, potatoes, rice, etc. and, as far as I know, are not suffering brain damage as a result.
While tooth whiteness in the US is often divorced from tooth health, fluoride does add a yellowish tint to your teeth, so the healthiest teeth — those imbued with fluoride — are slightly yellow. (In fact when they first decided to add fluoride to water, one of the questions was just how much they could add before your teeth would turn completely yellow. Health-wise the yellowing was fine, but it was obviously visually unappealing.) Ugly teeth may be due to poor/lack of orthodontia, but it's probably not due to better dental care.

My comment didn't add much in the way of discussion, so it probably should have been downvoted. But like you said, Rust isn't making a dent so far, and it'll take much more than memory safety to convince the industry to switch to e.g. Bevy rather than the big 2.
First of all let me say that I think this is a really great zine. I'm not really a zine guy, but I'm really excited about this. But, gently, let me say this format kind of sucks for reading. I generally HATE reading on paper, but this had me saying "I'd buy this on paper". My biggest gripe is I read partway through last night, and then wanted to go back to it today and my browser "suspended" that tab so I'm back at the front page. Probably like if I laid down a print pub. ;-) I guess the right answer there is to download and open it in a pdf reader.

All that said, I'd encourage you to NOT switch to HTML and leave it as PDF. There's something about it.
Please define appropriate levels and then cite some evidence that proves with high certainty that level is safe.

For the sake of argument, assume that only 1% of the US has levels that harm IQ. Would it not be worth it to remove fluoride from the water to improve the intelligence of 1% of the population? Especially when you consider we can get fluoride from toothpaste?
You are making a lot of assumptions to fit your narrative, the higher natural source would also be cumulative with toothpaste etc.

There is no conclusive data to support your assertion and there is a lot of data to support the benefits of fluoridation.

Did you actually read any of what I posted to understand it or is your mind already made up?
> Even though DebugAny inherits from Any

I'm going to push back against this terminology for the sake of people who don't know Rust and are coming from traditional OO languages.

Rust traits don't "inherit" from other traits, they "require" other traits.

So if I have two traits, where one requires the other:

trait Foo {}

trait Bar: Foo {}

That doesn't add Foo's methods to Bar's list of methods, like you might expect from the term "inheritance".

Instead, it just means that it's not possible to implement Bar for a type unless Foo is also separately implemented for that type.

Despite this it's still accurate to say that this enables a supertype/subtype relationship in certain contexts, but be careful because Rust isn't a traditionally OO language, so that may not always be the most useful framing.
That's a great idea. Good luck with the project!
Of course, amazingly that's one of it's best features, enabling you to actually speak to a real person. (it's a type of personal connection that fleshy robots have, for some reason, derided.)

But I digress, excusing your bad form of answering a question with a question, I am interested in your opinion of the possible conundrum of the two phone idea.
Has this link been found to not exist in fluoride supplements or fluoride toothpastes?

I don't think it's such a no brainer if every health org is recommending fluoride, and some people think it's scary.
Why did you omit the sentence immediately after the one you quoted?

> The NTP review was designed to evaluate total fluoride exposure from all sources and was not designed to evaluate the health effects of fluoridated drinking water alone.

…or the following sentence, which they bolded to ensure the reader wouldn't miss it?

> It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ.

So no, they very explicitly did not find that fluoride in drinking water concentrations was associated with lower IQ.
Rust has had significant OOP features since the beginning. Trait methods, dynamic dispatch, inheritance, bounds, etc.
From my own experience, this isn't true at all. Maybe your social circles are like that, but in my world it's quite common for people to profess open ignorance of the basics of operating a computer, and they sometimes even take pride in it.

You seem to be saying that because Lithium and Flouride are both naturally occurring minerals, that would make it okay to put Lithium in the water supply.

There's this dynamic in the industry in which a brash young project comes out swinging against some established technique and commits early to its opposite. Then, as the project matures, its authors begin to understand why the old ways were the way they were and slowly walk back their early stridency --- usually without admitting they're doing it.

Consider Linux. Time was, metaprogramming was BAD, C was all you needed, we didn't need dynamic CPU schedulers, we didn't need multiple LSMs, and we sure as hell didn't need ABI stability. Now we have forms of all of these things (for the last, see CO-RE), because as it turns out, they're actually good.

In Python, well, turns out multiprocessing isn't all you need, and a free-threaded Python has transitioned from impossible and unwanted to exciting and imminent.

In transfer encodings, "front end" people thought that JSON was all you needed. Schemas? Binary encodings? Versioning? References? All for those loser XML weenies. Well, who's the weenie now?

And in Rust? Well, let's see. Turns out monomorphization isn't all you need. Turns out that it is, in fact, occasionally useful to unify an object and its behavior in a runtime-polymorphic way. I expect yeet_expr to go through eventually too. Others are trying to stabilize (i.e. ossify) the notionally unstable ABI, just like they did to poor C++, which is now stuck with runtime pessimization because somebody is too lazy to recompile a binary from 2010.

As surely as water will wet and fire will burn, the gods of Java with stupidity and complexity return.

Agreed. This book helped me really understand the people in a country are not all defined by the ruling party or the ruler. In this case, not all Germans were Nazis and some had much honor in how they conducted warfare. Maybe this was obvious to many people but it wasn’t obvious to me until this book.
And how does the fluoride get in the water? Our water tastes strongly of chlorine because we are near the treatment plant and they put in enough so that it’s still effective at the edges of the system. I don’t know if fluoride works the same way, but what makes people think it’s always added at exactly the right levels?
