It is a simplified model. The obvious next question is why doesn't the entire lake freeze from the top down? Why does the ice not get progressively thicker every day? The next-level is to model the thermal insulation of the ice. Heat from beneath is insulated from the cold air above. With a constant supply of heat from below but a reduced heat transfer due to the ice/snow, along with reduced evaporation, it is theoretically possible for the depths of a lake to get warmer once frozen over.

react-testing-library isn't the "official testing library" for React, it isn't made by the React team, and testing library provides testing libraries for other frameworks.

It's just a change from an outdated, unmaintained testing library to a more 'modern', well-maintained library. There are also some philosophical differences in the testing approach.

The integer part is easy, since we already have the integers. Once you have D=[0,1), then you can define R=ZxD. That is to say, this definition of R seperates out the integral and fractional components of every real number.
Solving Design Hurdles in the Crypto World
Hello HN Community,

I'm excited to share a solution to a problem that has been a constant challenge in the crypto design space. As a designer involved in numerous crypto projects, I've repeatedly encountered the same frustration: the scarcity of quality UI elements and design inspiration tailored for crypto applications. Whether working on tokenomics, roadmaps, NFT cards, or dashboards, finding the right elements often meant hours of searching with limited success.

Determined to find a better way, I created Design Wizard. The platform's mission is straightforward: to provide crypto developers and designers with a comprehensive resource of beautifully crafted, ready-made UI kits and templates specifically designed for the unique needs of the crypto space.

With Design Wizard, you can now easily access a variety of high-quality design elements, streamlining your workflow and enhancing your project's visual appeal. No more endless searching—just intuitive, aesthetically pleasing designs at your fingertips.

Check out Design Wizard and elevate your crypto projects with ease. I'd love to hear your thoughts and feedback!
do you have links to that, even if it is in german ? Would like to know more

> It's likely that you live in an area with similar mortality risk from air pollution.

They're not really equivalent, unless you've got a high-risk condition like asthma.

Statistically speaking, a 100% chance of losing one year of lifespan (out of the 76 years an American can expect) is a greater mortality risk than a 1% chance of instant, immediate death.

In fact, if you're aged 26, a 1% chance instant death has half the mortality risk - and the older you get, the better it looks.

However, if you look at humans' revealed preferences, people would much rather lose one year of lifespan than take a 1% chance of losing their entire remaining lifespan.

Mortality risk isn't a very good predictor of human preferences, it turns out.

Same here. I lived in some of the world's largest cities most of my life, and loved the "big city" atmosphere. But in my late 40s it changed and started to crave being out in the countryside, away from people, noise, etc. I now live on the outskirts of a medium size city (in 5 minutes I'm out among orchards and vineyards), but would prefer to be even further out, have an orchard or small farm (though I have no illusions that I could make a living from that)
For a read-only filesystem, as a shared directory between guest and host OS for a specific guest (and host) users, etc. It's a significant, potentially dangerous limitation, but it's still worth having in its current form. Touching the VFS interface is easier when the code consuming it is already in the tree and not to be taken lightly.
If it’s commercial farming, yea it’s not fun. Exposure to many chemicals/pesticides/herbicides. Animal cruelty on a daily basis — those poor chickens and cows stuffed into tight spaces.

But if it’s for sustaining yourself, it’s not so bad.

Personally, the only “farming” I would pivot into is vertical farming. The idea of turning what would normally be a massive operation out in the country into a self sustainable, climate controlled operation in an urban environment is fascinating to me.

Optimize crops for taste rather than pest or weather resistance. Combine it with the fact that transportation can be reduced significantly; and it’s a recipe for a circular and self sustainable ecosystem.

Not all farming is large scale.

A lot of actually viable commercial farms where I live are smaller than many hobby farms in the US, for a start.

What a lot of people mean when they say they are quitting to take up farming is pretty much hobby farming - where you may break even or turn a miniscule profit, but the main “goal” is to simply become a bit more self sufficient and do it for some sense of enjoyment.

The interesting thing is some small “hobby farms” are effectively experiments in permaculture or other forms of regenerative “living” that can be extremely cost efficient or even profitable.

Agreed. Well designed Airflow Operators (or taskflow) are basically the same level of effort as creating a box with a UI (honestly, easier IMHO), but the ability to go into code is important for every non-trivial pipeline.

It looks incredibly easy to use, which is a huge plus for small to mid-sized businesses that need a powerful API gateway but don't want all the complexity that comes with it. This really fills in a gap, from a reverse proxy that lacks features and an enterprise solution which is overkill and expensive.
Could you define what you mean by a galaxy being "rearranged" by a black hole?
Agreed, when the data is already in a table format (instead of an "object spider web") the idea to automate serialization makes more sense, it essentially becomes a "database problem". I would still very carefully consider what data columns need to be persisted and which should be reconstructed, and I wouldn't try to come up with a too generic solution.

For instance in some games it might not be necessary to save a reference to a targeted object, if the gameplay targeting mechanism picks up a target in the first frame after loading a savegame anyway (etc etc...). Whether that target is exactly the same as at the time of creating the savegame might not be relevant (but very relevant for other games).

I guess the TL;DR is: in many cases it might be much easier to come up with a specialized per-game savegame system instead of coming up with a generic savegame system that works for all types of games.
A lot of things you're referencing are quite ambiguous so it's difficult for me to understand exactly what you mean. For instance contraceptives have been widely available in many countries with healthy birth rates for an extremely long period of time. South America is full of such examples, as well as women who have long since played a major role in the labor pool.

As for what I was talking about, Russia is not the USSR. Following the collapse of the USSR, Russia (alongside all former Soviet nations) entered into a catastrophic era. Birth rates, income, safety, and basically every other aspect of life plummeted to dangerously low levels during the 90s, which throws off absolutely all data because of something completely unrelated to anything we're discussing.

Complex numbers are just pairs (real and imaginary) of Cauchy sequences of pairs (numerator and denominator) of pairs (positive and negative) of nested versions of the empty set. (modulo al the necesary equivalence to make this work).

So the natural number {{}} is canonical included in the complex numbers as [something].

Natural {{}}

Integer ({{}},{})

Rational (({{}},{}),({{}},{}))

Real (({{}},{}),({{}},{})), (({{}},{}),({{}},{})), (({{}},{}),({{}},{})), ...

Complex ((({{}},{}),({{}},{})), (({{}},{}),({{}},{})), (({{}},{}),({{}},{})), ... , (({},{}),({{}},{})), (({},{}),({{}},{})), (({},{}),({{}},{})), ... )

(And there are a few alternative definition, but I think they are even more messy.)
"...emphasize the difference between universal and existential quantification more. Quantifiers can be confusing..."

Right, I've uni math also formal logic so I've knowledge of universal and existential quantification, etc. thus an understanding of the issues.

You're right, that stuff's a bit too heavy for highschoolers. Perhaps all that's needed is to be told 'that at times these appear the same but later on you'll need to understand there's a mathematical distinction' then emphasize the difference aspect to drive the point home.

Even though it was a long time ago I mostly recall what the teacher said and whilst he gave a few examples he never emphasized that there was a mathematical difference and that it was an important fact to know. Matters became more ambiguous from our science courses, the use of 'equivalent' was very loose.

I reckon the same or similar should apply to other topics, calculus for example.
A better comparison for nuclear power is the airplane industry. No one goes into the bridge running plant every day and runs the bridge for a living, with several people assigned to run a daily checklist on said bridge.

But it's still not a very good comparison, because airplanes, due to their very nature, can't be designed to fail safe. Nuclear power plants can.

In my experience SSO is high-touch. Sure there are self-service portals and control panes but big company IT departments are ticket processing machines, and it becomes a game of broken telephone to make changes. When something doesn't work, what do you do?

Offering SSO as part of an enterprise SKU offering implies there is a high-touch relationship out of the gate, and that there is a higher chance of success and adoption, including getting SSO set up right.

Furthermore many large behemoth corporations have strange SSO configurations and it's not unusual to require bespoke configuration let alone debugging time.

> Shortly after its creation in 1942, the federal War Production Board (WPB) sharply curtailed or banned the production of nearly 300 items judged "nonessential" to the war effort. The manufacturers of the targeted products could either choose to convert to the production of items deemed to be essential, or try to make do with substitute materials. Some of the banned items were near and dear to American consumers, who would soon learn the importance of conservation.

If you're an appliance maker, and the government bans production of civilian appliances... how much are you going to fight over a contract to make them for the military?

I read your comment as saying that SSO is denied to “regular” (non-enterprise) customers because enterprise customers would buy the regular product if it was included there, thus pointing out that all the other “enterprise” needs (terms, etc) aren’t real?

YMMV, but in my experience this is less common than you think and is instead more based on the baseline costs of specific features or customizations the client wants.

In other words, it’s rare to have a huge variation of costs given to customers for the same product, even if they are higher or lower for certain customers.
This is why any faster-than-light travel must either be impossible or mean that that traveling backwards in time is possible.

I point my telescope at a planet four light years away (I have super advanced telescope that can see these details), and use a worm-hole or other plot device to teleport instantly to that spot. Where do I arrive -- at what I observed, or at some point in empty space because I've just arrived at where that planet was four years ago?

If the former, I must somehow have traveled back in time by four years to arrive at the spot I had observed.

If the latter, I suppose we could instead say our destination is where we calculate the planet will be four years from now. Except that my travel time was instantaneous, so again either I've arrived too early and need to wait around for four years, or I jumped 4 years into the future (at which point that's not really FTL travel, just kind of stepping outside of time into some nether state for four years).
Yes and no.

Railways work well in the center of bridges. One bridge that violates this principle is the Manhattan Bridge; it was built before we had fancy engineering simulations or much experience with railway suspension bridges at all, and so the lower deck is a pair of railway tracks on either side of a roadway.

This unusual design is very stressful on the bridge and has resulted in expensive rehabilitation programs.

Bhyve (FreeBSD's native hypervisor) already contains a 9P over VirtIO "server". The protocols allows virtual machines and their host to share a directory instead of block storage without having to configure and use a network filesystem like NFS. It's even bootable as in the UEFI BootROM should be able to read the bootloader via 9P, the bootloader can use EFI boot services to read the kernel (configuration, kernel image, kernel modules), and the kernel can than mount it as root filesystem. This means that use a directory instead of an image to boot a virtual machine. I can imagine a lot of use-cases for this e.g. a CI/CD pipeline that tests an experimental kernel (feature) inside a hypervisor.

> forcible government breakup of an organization is clear state control of it

You’re defining control in a way that extends to all regulation.

The AT&T break-up has been heavily cited and written about. Do you have a single expert who agrees with your claim that it constituted nationalisation? (Let’s even assume AT&T was actually ordered to break up, versus voluntarily doing so to settle a lawsuit.)

Or alternatively:

1. Programming in very concrete/practical terms because you do not know how to think in precise and abstract terms (do not know math)

2. Thinking more precisely and abstractly (more mathematical way)

3. Only do some key important abstractions, and being a bit hand-wawy again in terms of precision. The reason: important real-world problems are usually very complex, and complex problems resist most abstractions, and also being totally precise in all cases is impossible due to the complexity.

All-in-all it is due to increased complexity in my opinion.

Example:
1. Writing some fun geometry related programs 2. learn about geometry more seriously 3. write software based on a multiple hundred thousand line CAD kernel.

Other example:
1. Write fun games on C64 2. Learn about computer graphics in University 3. Contribute to the source code of Unreal Engine with multiple million lines of code with multiple thousand line class declaration header files.
