But are any of your knives made from sand cooked in a microwave?

My understanding is that the claim is sharpest knife that was made in that fashion, not sharpest overall knife.
I too find it unfortunate, that is why i am a bit picky about it. Nothing changes if people don't ask for change. I would find it in much better taste if your policy tells what you do instead of focusing on creating legal room for what you say you don't.

What i find most interesting is the metadata piece. Photos often have time and location information attached (exif), especially if your service sits close to the camera.

You reserve the right to harvest those. Why? (It's a rhetoric question: the answer is of course: the lawyer said such wording protects you from getting sued)

Ask HN: What is your trick to do deep work or study?
The topic is very important to me, and I believe it should be important for any learner. I read Deep Work and loved it, but I think it is just one step in the right direction. We need to think more about it. How to lose yourself with the book or in your work. That skill that became very rare. I am assuming that there is knowledge out there somewhere that could help. So do you have any tricks for that other than the usual (like quitting social media)?
You were right - Javascript lacks a modulo operator. Javascript does have a `%` operator, and in many languages that performs the modulo operation ... but in JS it actually calculates the remainder. This is confusing because in some situations remainder and modulo look similar, but they're not. So if we compare JS and Python (where `%` means "modulo") ...

$ python3

In the case we're talking about - is_odd - I don't think it matters, but there is a difference and it could cause some surprises if you're not prepared.

edit: I called this operation "remainder" ... but you don't exactly say "10 remainder 3" for this operation. I don't know what to call it, "divide-by-and-return-absolute-of-whats-left" is not very catchy
>Has that historically been true though? Why then have China and India not always led the way as super powers in the first place?

Yes. Who said they hadn't?

For the biggest part of history, until Europe got forward after kickstarting the industrial revolution (along with the help of colonization and the exploiting of the New World), China was the #1 economy worldwide, and quite more advanced in many ways than the rest of the world.

E.g. in the Song dynasty (900-1200 A.D): "These [policies] made China a global leader, leading some historians to call this an "early modern" economy many centuries before Western Europe made its breakthrough".

1500 A.D.: In 1500, China was the largest economy in the world, followed closely by India, both with estimated GDP's of approximately $100 billion. France was a distant third at approximately 18 billion, followed closely by Italy and Germany. What is now the United Kingdom ranked 10th, at barely one quarter the output of France (Figure 1).

Heck, China was prosperous all the way back to 20-100 B.C ("Technological innovations, such as the wheelbarrow, paper and a seismograph, were invented during this period")

"China's economy led its European counterpart by leaps and bounds at the start of the Renaissance. China was so far ahead, in fact, that economic historian Eric L. Jones once argued that the Chinese empire "came within a hair's breadth of industrializing in the fourteenth century.""

I really love seeing projects like this.

My humble two cents is that in past projects I've often found the process to create the CSV that goes into a model is often much more time consuming and error prone than actually training a model. I really love the dataset operations that are provided.

Do you have any thoughts about what a gold standard library for data preprocessing would look like? If you have any plans to move further in that direction? Any projects that you find compelling in that space?

Plenty of upmarket cars have these types of settings, and are routinely praised for it.
Interesting and suggestive, but difficult to interpret from the publicly available information. Actively speaking two languages no doubt implies complex correlations between wealth, status and circumstance.

The paper abstract doesn't mention controlling for location. That would also be an interesting thing to test.
> Why would your A records change depending on context?

Good grief, usually it's because of a hairpin nat. People do that to themselves. They damage their own L3 networking and then decide that they need to damage also their entire DNS as a workaround.

It's a regular mind virus, because it's easy to implement split-horizon DNS but enormously expensive to remove it. People get used to it on one company and go and spread it on another company.

Just do a snat+dnat. These networking boxes are so expensive because they are meant to handle it, so let them do their job already. Or go IPv6 and get rid of DNAT altogether.
My theory is: When something is down, people may be upvoting to show sympathy / trying to bring it up again. Who knows

More like the moment you add a second Mutex in your app, ad-hoc handling and no policy to prevent deadlocks.

The solutions are well known and I'm simply sad to see them far too little used.

But in the case you insist in doing that (not using architectural solutions, some of which can be checked statically), yes of course runtime deadlock detection is a very valuable tool. I agree that it is even useful if you rely on policy but can't automatically check that they are respected.
TL;DR: TFA claims climate change don't real. Money quotes:

"Recent popular conceptions of the Anthropocene risk making a similar mistake, drawing a thin bright line at 1950 and describing what comes after as a new, modern form of ecological disaster." (implying that what's happened after 1950 isn't an ecological disaster)

"In the ‘pristine myth’ paradigm ... human societies are recent destroyers, or at the very least disturbers, of a mostly pristine natural world." (implying that human-caused climate change is a "myth")

If you read the article you'll find it's using a lot of double negatives like the ones above, and a lot of innuendo, but it ultimately boils down to denying that humans are causing climate change right now and we need immediate political change to reverse it.
You have a business where you regularly seperate beach sand into its components and make a knife out of it and sharpen them?

The claim here is not that this is the sharpest knife ever and it just happens to be created in a home lab using sand and a microwave. The claim is that among all knifes made from sand, using a microwave, this one is the sharpest - and I am not convinced that you have such a knife, let alone one that is also sharper.
European powers were fairly dominant in the world when the industrial revolution started there. The causation link isn't clear to me (if one caused the other or vice-versa - I'd love to hear from people who know better), but the fact of the matter is that local energy sources could be used (coal, as early as the 1700s) so the benefits were clear and local first, and a huge jump in progress ensued across those economies over the last few centuries.

Transitioning to less "dangerous" fossil fuels happened once the economies were already pretty robust and machines were doing the work of hundreds of men at once, because countries got richer and as their quality of life improved they increasingly walked away from dangerous stuff (the deaths per TWh of coal and brown coal are horrifying[0] and unions and education of the population surely had their role to play in driving change in the way those countries dealt with fossil fuels).
Europe then increasingly moved away from coal (not quite done with it though: Germany is still so anti-nuclear that they are the second biggest users behind Russia and iirc the first next importer of coal-based energy - from Russia), but that's the kind of luxury one can afford when the economy is already in decent shape. That's also in part why, while currently China is the single largest producer of coal in the world (to sustain its growth year-on-year), they're also pretty aware that they've got to switch pretty fast to something better (i.e. nuclear) because the honeymoon won't last forever (and I have no doubt that a few generations there will pay a high price in the future for that - cue social unrest down the road).

So at the very least, the idea that we can "throw people at the problem" isn't entirely devoid of sense when you consider how many people in Europe dedicated their lives to this brand-new energy-dense coal for a couple generations, and in doing so definitely sacrificed their health and lives in exchange for rapid social progress (that they might or might not have benefited from..).

> This sums up how I feel about the whole tiktok/huawei thing as a European. An interesting part of it not mentioned in the article is how the USA also pressures European countries into applying the same rules.

The US has a treaty obligation to protect (most) European countries militarily, particularly from Russia but to a lesser extent from China and other countries in Asia. This is a partnership of course, and America's European friends contribute, but the bulk is still borne by the US for obvious reasons (gigantic military budget, global deployment, desire to preserve peace between France, Germany and the rest of the continent).

All of that is to say, for better or worse, the US feels that it can apply pressure. Brussels may not like it, but Washington knows Europe will choose America to Putin's Russia or Communist China most of the time.
Looks correlative but it highly correlates, and they did seem to eliminate a lot of confounding factors.
On priors and given how they sample, I'm guessing it's just p-hacking.
Sure they do. But at a huge cost for our society.
> Arguing in favour of the virtues of a corrupt system

Didn't do that. Pointing out something exists isn't the same as arguing in its favor.

I don't believe that either. As I already said, I have no particular opinion about this case.

What?
It’s so incredibly damaging to the institution of the Presidency that you can’t trust a single word of any of these people. Who has the credibility right now to provide an update on the health of the president? Maybe Fauci?
One of the first things it mentions is controlling for location -- they were all in Barcelona.
> You don't really need 750 million people when you have 1.6 billion in the first place.

Why not have both?

China should in no way have to be “Western” to be trusted internationally. But they could embrace the opportunity to be even more open and generous of a society than they have been in the recent past. They’re certainly strong enough for it.

A few things I would personally love to see:

– More transparent and consistent application of laws

– Celebrate and protect all Chinese of all diversities, not just the majority who hold the most power

– Avoid taking nationalism to an extreme

The second and third especially are serious mistakes other nations (e.g. Britain, Japan, America) have made in recent history. It would be a gift to see China avoid the same.
With proper random sampling you only need something like N = 27 (I forget exactly) to reach p = 0.05

Assuming random sampling, it's a misconception that you need ten thousand participants to have a useful study.
It has and does all of these things, but it does not have runtime binding, therefore by definition is not object-oriented.

Concretely, you cannot take a Container pointer and point it at a std::set. You can take a T, and bind T to std::set at compile time; but that is Generic Programming: analogous, in some ways, but not the same.

In the '90s it was fightin' words to say "X is not Object Oriented", because Object-Oriented was taken as a high-status way to say Good, and "Not Object-Oriented" translated implicitly to "Not Good".

But in our brave new world, object-oriented is but one design discipline, and we have others, and enough language primitives to construct our own disciplines by mix-and-match as problems dictate.

And, I have myself simplified code that had used a virtual function to use, instead, a function pointer, and it was (still) Good. Better, even.
How much are you willing to bet? :|
> Gone are the days when gamers only cares about single core performance

Unfortunately that's not true.

I closely follow popular hardware subreddits (which are disproportionally gaming oriented) and read a fair share of comments every day. The old mentality is still prevalent. The limit gamers care for multi-core is the # of cores game consoles use. People still happily recommend a 4-core CPU over a 6-core CPU with ever-so-slightly-lower ST performance for new builds.
>If China became democratized tomorrow, overnight, with no attendant problems, they'd still speak Chinese and the rest of the world still wouldn't know 3 words of it.

The world didn't know 3 words of French when that became dominant "linga franca", and din't know English when that replaced it, either.

People learn X's language because there's an advantage of knowing it and doing business with X, they don't do business with X because they speak their language.

The future language will probably just be some bastardization of English and Chinese, with some Spanish thrown in...
> Well, you get a problem solved. One that was probably bothering you or stopping you from doing some work.

You ignored the entire premise. Weird, because I repeated it multiple times. (And I don't understand how the comment can even make any sense unless you get the premise.)

To be clear: the scenario outlined above is one where I'm filing a bug report against a software project that I do not use and do not ever intend to use. There's no way a bug in the software can be showstopper for me if the software in question has no effect on the success or failure of whatever show I'm running.

Well, the Chinese have some historical reasons to be cautious as they had been invaded a few times by the Europeans, whereas they hadn't done the revervse themselves...

Apple has already confirmed that they have no plans on restricting the ability of third party operating systems to run on Apple Silicon based notebooks.
Hm, isn't it the other way around? In the 90s, the technologies that made the internet boom were things like Linux, Mysql, php, which were created in europe (with great US contributions). . Google wouldn't be able to commoditize its search so easily otherwise. US companies were (and are) great at consumer-facing tec. It's in the past decade+ that the US has become dominant in just about everything tech (largely because of the cloud and mobile). It has also become excessively dominant in the media (outside china), so dominant and centralized that american outrages end up becoming global outrages. When was the last time we saw twitter trends coming from outside the US? There is a war going in on armenia, yet overshadowed by a US debate (before potus got covid, which overshadows tonight's alien invasion). All operating systems that have substantial user base are now made in US.

Even the TikTok case is telling. Many european countries do not wish to have bad relations with china, or don't see them as a threat, yet they 'll follow suit in banning it.

I think it's the other way around. There is too much americano-centrism in the internet now, and that s a problem because it's being filled with increasingly more numerous and more rigid american rules (gone is piracy, subscriptions for everything, app stores, gatekeepers everywhere). This is a culture that is not fun, and consumers will take note. TikTok is probably just the beginning of people searching for new toys outside america's walled garden.
Cue “p = 0.05 is a random choice” and a big thread about p-hacking. Any takers?

It feels like everything to say has already been said about the bias of small sample sizes and the dangers of p-hacking. But it also seems like the discussion is inevitable here.

I wonder if there’s a new insight to glean, somehow...

For a background on why p-values are misleading, see https://youtu.be/42QuXLucH3Q which is excellent. He points out that 0.05 was selected by Ronald Fischer in 1925, and people have gone with it since.
Isn't the crux just that, "proper random sampling" can be quite hard. Assumptions are fine in theory, in reality, they can seriously throw us for a loop.
Since eradicating the virus has become impossible, most national governments are currently pursuing a herd immunity strategy by default. They're just doing it at slightly different rates.

In the USA the current daily rate of confirmed new cases is about 43000, not 55000. However there are a large number of "dark matter" cases not counted in official statistics. About 40% of infections are asymptomatic, and many more are paucisymptomatic. Most of those patients never get tested.
In "The Datacenter as a Computer" there was an interesting diagram sketching a datacenter memory hierarchy latency and capacity and bandwidth to access RAM, SSD, and HDD in the same machine, the same rack, and a larger cluster. It's page 72 of https://www.morganclaypool.com/doi/pdf/10.2200/S00874ED3V01Y... and with luck https://books.google.com/books?id=Td51DwAAQBAJ&pg=PA72 will get you to the page. The numbers have changed (commodity SSDs have markedly improved!) but the idea still makes sense.

Fun to consider that boxes under one top-of-rack switch can hold dozens of TB of RAM and hundreds of TB of Flash with latency measured in µs between them. There's legitimately interesting space in between writing code for a single machine and code for huge, spread-out clusters of thousands of boxes.
It seems that his objection is he "homogeneity" of the population, they're all from Barcelona, if the sample had different locations I think he wouldn't object the small number( e.g N = 30 ).
Or just not being someone born in the USA to non first generation parents.
Probably cheaper to slot a component into your HVAC than it is to re-engineer it to draw outside hot air, cool it, and still keep interiors at a comfortable level. (Reverse for winter)

What "ethics"? This is Europe, of the conquest of the Americas, the colonization of the world, WWI and WWII, and so on up to 2020, we're talking about, not Mother Teresa.

Project Astra Scholarship Programme
Apply here: https://astrasum.com/projectastra

Astrasum focuses on building the future of learning. We break down your learning behaviour into elements and hack each and every one of them with tech.

As Astrasum is rolling out high-powered features in development, we are launching an annual scholarship programme, Project Astra, for a cohort of 10 scholars that wish to contribute to transforming the way we learn and defining the future of learning. If you're selected, you will...

- Get on a fast-track route to accelerate your learning ability with some of the most talented tech founders, scientists, engineers, philosophers, and autodidacts
- Gain advance access to all the experimental deep-tech features in development
- Join an exclusive group of extraordinary peers to do cool things together
- Participate in weekly workshops with expert guests
- Win an internship or job offer from Astrasum after the programme potentially
- Receive a 1-year Astrasum Plus subscription for free
- Pioneer a project related to learning with all the resources you need
- Change the world in your own stupendously weird way with us

This programme will be run in English, and therefore the only hard and fast requirement is that you're a fluent English speaker.

Besides that, we love that if you’re weird and ambitious but not world-weary and cynical. If you would laugh at someone because you think his/her idea is stupid, then this is probably not the right programme for you.

Nevertheless, if you’re the kind of person that’s not afraid to experiment with what others might think as crazy, hop on board!
