Yes, this exactly. Like I know that one freelancing platform is Fiverr (I had to google the exact name right now), but I first typed Fivver. And with all of the crazy start-up names no knowledge of spelling can help you.
I am not talking about numbers in R. I am talking about representing numbers from Q in a decimal fraction. (Or in a fraction to basis 11 or 12 or 60 etc.)

(I'm not sure why anyone would want to bring up R? Why R and not eg p-adic numbers? Or algebraic numbers?)

General case: your fraction p/q will be expressed as some repeating decimal fraction, like 22/7 = 3.|142857 (where | marks the start of the repeat.)

Special case: your fraction p/q will be expressed by a decimal fraction that stops. Like 2/5 = 0.4 or so.

You can't get rid of the general case. No matter what base you pick, the representation of the vast majority of your fractions will have infinite repeats.

You can however minimize the occurrences of the special case by picking a base with fewer divisors.

In contrast, picking a base with more divisors, like 12 or 60 gives you more special cases to worry about.

(And yes, you can apply the trick you suggested, to sort of remove the special case by writing 0.4 as 0.3|9. Or for that matter as 0.4|0; but I'm not sure that last one buys you anything.)

Just to be clear: this is all a bit tongue in cheek and just talking about what system is mathematically more elegant, by having fewer special cases. In practice, having more divisors is convenient; though in practice just rounding after some number of digits is also fine.

EMDR is fantastic for PTSD and helps with some C-PTSD, but for a lot of people with C-PTSD, it only retraumatises, and a lot of EMDR practitioners seem unaware of this. Internal family systems can be a better choice for C-PTSD sufferers.
The liberal/conservative gap is interesting. How much of that is due to religious or spiritual practice? What do we find deep meaning in now? For so many who are drawn to movements like effective altriusm, might that meaning come from a focus on challenges the world is facing. Does that focus dwell too much on the negative?

It's hard for humans to fathom timelines beyond our life span. But over the course of 100s or 1000s of years, cities can be abandoned and population migrates.

> But not so much with things that fuck with our minds. Religion is a phenomenon that changes our views fundamentally, and I can't say we have overcome its influence, despite it being around for over 5000 years.

Honestly, the change is the lack of religion in modern society. Maybe we'll adapt, maybe we won't.

As a personal aside, Ireland de-catholicised really significantly during my lifetime, and while I'm super happy about lots of that, the loss of community in many places is quite real.
The basic message from EU to innovators is: don't bother. If you manage to create a successful business out of your innovation we will punish you.

When I read the title, I thought the same as you. It caught my interest because it sounded nonsensical so I was excited to see the reasoning and merits (or lack thereof) of the approach.
I read this, and this article has a lot of words that I don’t know, and that make me feel intimidated for having missed out on something important for the last ten years of my professional career.

The first time someone told me about EDA was when I told them I had problems optimizing a certain SQL query, to which their answer was whether I have considered using event sourcing or storming.
Considering that object oriented programming began as a message passing and ended up as a request response paradigm (and the entangled mess it can be), I suppose event-driven will follow the same path.

One of the journals in my field is going through this at the moment. They were set up with an initial grant to cover editorial and typesetting, which is about to run out. Their two suggestions for carrying on are either to charge a couple of hundred dollars a paper for typesetting (which is apparently what it actually costs) or to require submissions in a standard LaTeX pipeline (which is not standard for my discipline but would enable it to be done automatically). I suppose a strict Word template would also suffice at the expense of annoying all the computational scholars (that's what another Diamond OA journal does in my field).

But somebody's doing the typesetting. Giving sufficiently technically competent authors that could be the authors, but otherwise some money has to be found from somewhere. I don't mind that coming from libraries or research grants if necessary: it's cheaper than Elsevier.

Man, it’s kinda scary hearing the “more similarity between any two humans” line here on HN. That one’s up there with the “we only use 10% of our brains” line, for me. My understanding is that’s a pretty well documented misconception about genetic diversity which doesn’t really apply here.
> each day has 24 hours 39 minutes and 35.244 seconds

> at midnight your martian clock would show the time as 24:39:35 for a fraction of a second

A similar idea could be to have exactly 24h 39min 35s each day (i.e. the last second before midnight is 24:39:34), then add a leap second every 4 days to compensate for the missing 0.244s, then skip it when the 0.006s errors cumulate up to 1s.

This just because in my opinion it is easier to live with leap seconds than with non-integer seconds.
Reddit is much worse than that. Reddit is a shrine to consumerism. It's almost entirely about consuming and buying stuff. Be it expensive computers, headphones, computer games, guitar pedals, modular synths. Or maybe it's about over-consuming bad news from your favorite political bubble, or from your city, or country. But it's a website that makes almost every single community regurgitate the same jokes and memes non-stop to the point it could perhaps be replaced already by ChatGPT.

"Oh but thanks to Reddit I found my dream headphones and I'm finally as happy as I was before finding /r/headphones".
Signoz: Our Philosophy on Pricing
Corporations are supposed to do whatever their shareholders want.

The default assumption is that shareholders want to maximize profit, but shareholders can also want different things.

In any case, even the most ruthless capitalist society imaginable is not made out of corporations alone. Corporations are just a legal shell. People work for them, people own them, people buy their products, etc.

In a true profit maximizing meritocracy some disabled people might not get a job (though they still might, at lower pay commensurable with their productivity). [0]

But there's nothing stopping people from (a) charitable giving, or (b) enacting laws to give tax payer funded assistance to disabled people.

(You might argue with (b), but you can't really argue with (a).)

[0] Compared to eg someone like John von Neumann, I'm an idiot, but I can still find work even with my comparatively weak intellect. I just can't expect as much pay as John von Neumann would warrant. Of course, that pay might in principle be low enough that people can't survive on it. That's where charity and/or public assistance comes in.
Ms GPT answer to the same question (no mention of China in the origins):

"The Pythagorean theorem is a well-known geometric theorem that states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (britannica.com). It is commonly attributed to Pythagoras, a Greek philosopher and mathematician who lived in the 6th century BC (talesoftimesforgotten.com). However, some historians doubt that he actually discovered this theorem or even engaged in any kind of mathematics at all (talesoftimesforgotten.com). There is evidence that other ancient civilizations, such as Babylonians, Egyptians and Indians, knew about this theorem before Pythagoras (en.wikipedia.org)."

The core idea is that something becomes so addicting that you lose the ability to do anything else.

Concrete example: A few years ago I decided I had enough technology usage and started to taper off and remove many devices from my living spaces. As I did this, I regained the ability to do more things. Some of those things involved writing a couple books(one on this topic specifically). Some of those things got me promoted at work. Some of those things had me present in my kids activities. Some of those things had me building a community around a new sport I've never played -- basketball.

>shared phones between 12-16 (with other siblings or the “house” cell phone that also can be used by parents)

lol good luck trying to enforce that when almost every 12 year old kid has their own smartphone today. 'Your' kid will most certainly feel left-out,different and noticed and will be commented on by their friends.

> model good behavior yourself. No phone out when your kids are around.

Yeah I dont think this is a really effective way to go about this, sure I get your point, but parents(or adults in general), have way more responsibilities and pressing matters to attend to. Not saying thats always the case, but its an apples to oranges comparison here.

Loneliness Reshapes the Brain
It's tricky. I agree thay phones are phenomenal distraction, but, they can be used for good or evil.

Until fairly recently, I got extremely dirty looks or even a talk from my boss, for bringing a laptop into a meeting. It was of course fine to bring your notepad and pen, but I type about 10 times faster than I write, and I can actually read it later. It ends up just being Luddite discrimination.

A few times I tried taking notes on a phone. It's always with me, the notes are electronically connected, but prejudice of me "not paying attention" was too strong to overcome (even though I'd send structured and summarized notes to everyone).

So in turn I've developed this weird distaste of notebooks and their (over-)privileged status in our society :-D
Ehh. I think the author is a little blinkered here based on these examples.

Right, drilling oil from the ocean, then shipping it to a refinery then driving it to a station then putting it in your car is some how more efficient than a solar panel running electricity through an inverter into your car.

This a tricky one.

> If the group is at least somewhat big, chances are they'd have been approached by companies before

The approaching took place in the past, so I'm not sure I follow why using "is" makes anything present tense other than the conditional clause? The group must be "at least somewhat big" in the present for the conditional clause to be true, and the main clause is somewhat separate.

The expansion of "they'll have been" is "they will have been", which sounds perfectly fine.

In my mind the expansion of the original sentence would be, "If the group is at least somewhat big, chances are they would have had been approached by companies before". In spoken communication you would likely drop that "had", but it's also perfectly normal to contract it as OP did. But in written form I think it's too much of a stretch to replace "would have ha" with an apostrophe.
Ah the famous Tade0's-experience-price-index /s :)

Sure, I'd love to see how prices in small shop chain retailers compare to big box chain retailers. But sorry, your personal gut feeling is not data enough for me.

As for walkable cities with zoning and parking minimums, perhaps it can technically be done? But you do agree that it makes it extremely difficult and disincentivised, right?
I would support the use of this on Earth as well.

I love that feeling when the clocks go back in Autumn. This would give you that every day. My natural circadian rhythm is about 24.5 hours. I enjoy the dark, and this schedule would provide variety as our waking hours cycled in and out of phase with the sun.

And it would make scheduling regular Earth-Mars communications much simpler.

It is better for the market to decide. Otherwise you will have some small percentage of people who have excellent reasons why their particular area should receive a disproportionate amount of money.
China could use these ships as described, but they’d first have to disable Taiwanese defenses and keep the US out of the area, in which case the war is already over. If China were to just send boats like these across the straight without the prior conditions being settled, they’d be sunk and sunk easily since they’re defenseless. Seems like fear mongering to me.
Iceland and the Falklands would likely be respectively -9 and +12 from Japan.

Greenland is probably the best reason to keep Greenwich as the reference time zone. :) Most of the population (so to speak) is on -13 to -12. I have no idea if the people there have more ties to continental Europe and Iceland, or to Labrador.
You didn't specify to what depth, though:

- With goose down having a density of 0.00286 g/cm^3.[1]

- The area of a football pitch being roughly 0.714 hectares.[2]

You could cover one football pitch to a depth of nearly 50 meters:

You have: (1000 tonnes / (0.00286 g/cm^3)) / 0.714 hectare
You want: m
* 48.970637
/ 0.0204204

(Using GNU Units.)

If you spread the feathers to a depth of 1 cm, you'd get roughly 5,000x more coverage, or 5,000 football pitches. Give or take.

Rather nihilistic and blunt, goes nowhere. The animation was good and aesthetically pleasing. I half expected the 1998 film of the same name and there is a fair amount of overlap between them but its bluntness and nihilism serve a purpose which this seems to lack (or I missed). I look forward to digging through more of this persons animation, thanks for posting this.
Yeah, the fundamental physics constraints of this approach are pretty wild. The cross section peak for the candidate Proton-Boron interaction is at about 10 times higher energy (i.e. temperature) and the peak itself is roughly a fifth of the Deuterium-Tritium cross section. Oh and each individual interaction produces less than half the energy. So 100x more difficult is actually not far off in that sense. That means you don't just need a lot more energy to sustain the reaction, you'll also get a lot less energy from it. This is a very long and steep road to net energy production and there are good reasons why noone has bothered with it so far. The only upside is that you produce more charged particles, which are easier to control and extract energy from and they also cause less radiation damage. But if anyone ever makes a reaction like this work, by bet is still on Helium-3. But we won't be able to make use of that until we have scalable mining industry on the moon's surface.

I think Twitter definitely goes both ways. It encourages and legitimises an ocean of garbage discourse. But then there are also people who use it as a tool for legitimate art.

Personally I think of those accounts when I try to justify staying on the platform. It's not a reasonable justification but somehow it keeps me there.
There's also the possibility that even things that are better or at least not-worse, are not moving in the right direction anymore.

For decades, almost everybody agreed that civil rights, human rights, democracy, equality and all that sort of thing, were good things, and it at least seemed like the world was slowly but steadily moving towards more of that. These last couple of years, it seems to have become appallingly popular to openly support and admire dictators, argue for authoritarianism, against democracy, etc. Especially after the fall of the USSR, there was a widespread belief that the threat of nuclear armageddon was over, those former communist countries would become democratic and everything would be better.

Something tells me there's a new agenda being pushed from the echelons that a lot of people in big companies are unproductive and I see some people are buying into it.

It's not the fault of an engineer if they are mismanaged or provided with leadership where they can actually ship useful products.

There's a lot of people working on things that dont produce monetary value for the company because someone decided it's necessary.

Do you think a lot of companies need all that insane machinery and automation to ship a trivial web page? Probably not.

A lot of work is done for vertical integration, indirectly driving new customers to your main platform or maintaining your existing customers. There's insane amount of manpower being allocated to work on app screens that will probably be used by a very few users.

Productivity cannot really be measured.
