America offers Medicare so we still bear the cost. Just only if they live long enough to receive the retirement benefits.

Yeah one heck of a perverse incentive.
Incidentally this is also why everyone working in a nation has to receive these benefits (and any others guaranteed to citizens), otherwise you get migrant workers who suck up this, quite literally in this case, but don't receive healthcare.
Yes, assuming the perp took the victim promptly to the hospital, I don't see why it should be qualified as murder unless there are antecedents.

I can relate to wanting to silence something very distressing/aggravating by any means necessary but as a Society we've decided that adults should know better and should be held responsible for such mistake/accident. And I tend to agree. So manslaughter it is.
Current mobile keyboards and screens are pretty much fine -- I have no issues with text input on a phone or with reading.

The problems are with editing only -- precise cursor positioning, precise selection, and then access to basic cut/copy/paste/undo operations that doesn't mess everything up.

My hunch is that we need a button on mobile keyboards to switch to a kind of "edit gesture mode". Some kind of swipe area to move the cursor, some kind of swipe area/mode to extend/contract a selection, some method to handle scrolling as necessary, some kind of magnifying zoom to select tiny things like narrow punctuation, and separate larger button areas for cut/copy/paste/undo. Maybe instead of swipes there are gestures in a kind of dedicated trackpad-type area of the screen, I don't know.

But I definitely think there's a ton of area for experimentation that hasn't been explored yet. The hold-spacebar-to-turn-keyboard-into-trackpad-to-move-cursor mode was a first step the iPhone took towards this, but I think it can go 20x further.

I think it's something that only Apple and Google are capable of developing right now though. I don't think there are enough API's exposed for third-party keyboards to directly control things like text selection, zoom, scrolling, cut/copy/paste/undo, and the like.
Ah that makes more sense. I recall one of the studies saying that the worms couldn't reproduce, whereas the article on HN mentions millions of eggs causing an infestation.
Not irrelevant. By definition, non-zero does indeed mean not zero, so that person's claim wasn't wrong, either

> you claim that it isn't true makes no sense either since this isn't a claim about a fact that can be true or false

actually, it makes total sense, because your factual claim was that, for a nonzero number, "you've achieved 0", which is obviously wrong. It's simple logic, friend.

maybe try tying your post back to reality, where the effect isn't actually zero? Fill in the analogy, since it's clear we can reduce our microplastic exposure a non-zero amount (your personal opinion that it's not enough for you is what is irrelevant here)
I am pretty sure it still is. I used it to lose 75 pounds last year. I am certain even if there was an increased risk of GI cancer (which I don't believe there is, it only shows correlation and no causation), it still is well offset by my improved health.
Car mechanics have a few cultural things that lead to everyone buying a preposterously expensive box of their own stuff. First is theft (stuff walks away a lot) and second is flat-rate differentiation. Having the right tools can make a flat-rated job take much less time and thus incentivizes the mechanic to have their own tools, and still would even if the garage provided them.

Not saying it's good or right, but there are incentives that push towards it.
You're not wrong, but I believe that we're talking of different properties.

Move semantics and borrow checker shine when you don't want your data structure to be shared and when you want to control mutation. In some domains, that brings you an unequaled level of safety and Rust is the obvious choice.

Move semantics and borrow checker slow you down when you sharing and mutation are properties you don't care about (or at least not enough to prove them to the compiler). In such cases, I'd rather code in OCaml (or Haskell, or TypeScript, ...)

I hope that one day we'll be able to have the best of both worlds, but I don't see a path forward at the moment.
> Because we have a public health care system, funded by taxes, having a large number of young men out of the work force (not paying taxes) and using the health care system effectively means my taxes, everyone's taxes, are higher.

The taxes part is the same; only the healthcare half is different.
> So suppose you went to one of those innermost territories and convinced the people there to join you and declare themselves a new independent state. Say some Pakistani territory inside some Indian territory inside Pakistan.

This wouldn't work the way you imagine. The fundamental reason the India-Pakistan border situation is so dicey is that the "percentage of population which is Hindu vs. Muslim" is a smooth gradient across the area. The British drew an arbitrary line through this gradient as best they could and called that the border, but no line can ever fix the problem entirely. But all the people involved are more loyal to their ethnoreligion than an actual abstract state-- that's the whole reason there's a dispute to begin with-- and proposing a new state based on foreign ideas of libertarianism would not be met with eagerness from anybody.
Quaternions cover SO(3). Useful for rotations in 3d.

Complex numbers cover SO(2). Useful for rotations in 2d.

Geometric algebra contains both of these and a bunch of others. Useful for generalizable operations in any number of dimensions.

As an example, you might be able to apply your intuition for quaternions to spacetime geometry.
Ima use this opportunity to advertise that I'm working on a mobile shader editor, an area even less adopted to the form factor and am using my structured code editing research[1] to smoothen the experience.

> While we should always take care of novice users first, we shouldn’t ignore proficient users.

I believe that the relation should be reversed: Make the best system possible, usable by well-trained users, and only then add easy modes, tutorials, child safe modes, etc. with paths for improvement at every level. But when using modern systems, I often feel like I’m reduced to using Fisher-Price toys with one (inoperative) button.
The silica content varies significantly based on the stone being cut. Engineered stone is apparently like 90%+ silica, with the rest being binders. Granite is apparently ~10-45% silica, while marble has a negligible amount.

There's a OSHA/NIOSH pamphlet linked through the original article (https://www.osha.gov/sites/default/files/publications/OSHA37...) with table and additional details.

The pamphlet said that in one study, a marble shop performing dry grinding (no wetting, nor other engineering controls) had airborne silica levels of 39-45 ug/m3, while a granite shop which also did not use engineering controls say 89-460ug/m3.

It's downright amazing to see how thoroughly the author challenged the statements by Avis's PR department - nearly everything they said was a lie.

I'm incredibly frustrated by how often the US press seem to cover something about a company being shitty by describing what they did, and then verbatim printing whatever a PR droid says, and not attempting to verify the statement or ask for proof.
> Nobody to blame but themselves.

Well, it depends on the situation.

If I, a factory owner, offer optional safety equipment that slows workers down a bit, but I also demand such high productivity that corners have to be cut - whose fault is it when the inevitable happens?

What if I, a factory owner, provide optional basic safety equipment costing $30 per person, but the mask makes the goggles steam up and the boots aren't comfortable? There's better safety equipment available for $300 per person - is it my fault for not buying it?

What if I, a factory owner, happened to start my factory by hiring macho tough guys who don't like wearing a mask, and subsequent hires learn that behaviour from them?

Generally I to listen to the craftspeople I employ on issues of safety because keeping them safe is the whole point of safety. But they and I have a shared responsibility to make sure, if they say the machine is actually safer without the guard, that they're right about that.
So in your view, you're qualified to tell us Hedy's preferred demonym, but Wikipedia is not?

> I think nowadays you can't properly set up a new state, period.

You probably can, but just not where people want to. It all comes down to whether your country wins the military battles that inevitably take place, and one modern soldier can really do a lot these days. The US exists, for example, because the British absolutely bungled the response to the revolution. Nowadays, it would take a lot more incompetence from their end to lose territory; if the ground troops are all neutralized, just hit 'em with an ICBM or something. It's crazy the amount of resources you'd be up against.

People are trying to secede from countries that literally have nuclear weapons. Your 3D printed guns aren't going to win against that. But, if you're fighting the local warlord or whatever, you probably have a chance.
Try My New AI Learning App – Sociask (Show HN)
Hey everyone, I'm Bilal and I'm excited to share that my AI learning app Sociask is now in early access!

I've been working really hard on Sociask for months - it uses advanced artificial intelligence to create completely personalized courses tailored exactly for each unique learner. No more one-size-fits-all education.

The app understands how you learn best based on your interactions. It then designs custom lessons and content to keep you optimally engaged and progressing at your own pace.

Even in this early stage, it's been amazing to see how well Sociask understands individual learners and creates such intuitively customized experiences. The results have far surpassed my expectations.

That's why I'm opening it up to friends and family in this early access phase. I want to get feedback from real users to continue improving Sociask before the full public launch.

If any of you want to be among the first to experience the future of personalized education, here is the link https://play.google.com/store/apps/details?id=com.sociask.ap.... I'd love for you to check it out and let me know what you think of the AI-generated courses. Your input will help me take Sociask to the next level.

I'm proud of what I've created so far but also very excited to see where Sociask can go from here. Thank you in advance for your support and feedback during this early access period!
So are you just drunk all the time instead?
The study is based on self-reported responses to “How many days do you generally consume breakfast in a typical week?” (in Chinese) ... it's an interesting question that clearly must have a customary/social component. As an annoying pedant I'd be compelled to answer "every day" based on the definition of breakfast as the first meal of the day. I don't know how the term or the custom translates to coal miners of eastern Tangshan province, though.
Yes. I posted in it yesterday, in my own "threads" I see the posts' age reflecting that, when I look at this thread they are now only a few hours old.
It seems to me, having observed other's retirements, that you still need to have a purpose, and a community of people to be with. This can mean many different things but having a compelling 'why' for what your are doing is the root of motivation. Ideally the community of people are also in a similar situation and working toward the same purpose. It often takes people a while to find such a thing.

It seems that you already know this but perhaps spelling it out is helpful.
You can equally say that git is for when you want to track changes. And then it's a failing of git.

Besides, what's the difference? It's a file. The contents changed. Git doesn't say anything at all along the lines of "30% or more different means it's not a good fit for git".

People had to deal with local language file names since Windows 3.1 at least and it became very common with Windows 95. Good luck if you wanted to deal with files named in more than 1 non-ASCII language (very common in Europe or the Middle East).

> It is possible to genetically engineer Streptococcus mutans, the dominant human mouth bacteria, to produce ethanol instead of cavity-causing lactic acid

I hope it's in such small quantities that it wouldn't cause any alcoholic effects?

Nonetheless, such a simple website with short and concise copy. Wasn't expecting that for a biotech startup. Hope it works, cavities suck!
Tangentially related, there's this copper mining museum in BC (1) in what used to be one of these corporate towns where you lived and died. They do a quick demo of the equipments they used back in the day, in a pre cut hole. Even with your hands on your hears it's painful, teeth chattering - and they don't even really hit the rock.

People working in there weren't wearing any sort of hearing protection and became deaf within months. And after introducing pressured air driven equipment, they were all dying in a few years from silicosis. Until someone added water spraying to precipitate the dust into mud (wherein their issue became to fiddle caked in mud all day long in the dark, which I guess is an improvement over certain death). Which happened years later.

Thinking about the kind of life they had terrorizes me. I don't get how, for the longest time, people were fine with that. I mean no judgement on the workers, they probably didn't have a choice - but the people sending them in probably saw them as kettle.

Makes you think about the sort of progress in worker protection that was made since then. But also this kind of story reveals how people are still ready to profiteer from such deadly practices, if given the opportunity.

Linux and MacOS use UTF-8. Qt, Windows itself, Java, Javascript, and (on Windows) C# will all use UTF-16.

Most computers run Windows, by a rather big margin. Even more computers use Javascript. Are you running KDE? Don't be surprised if half the text in your screen is secretly UTF-16!

UTF-8 is definitely better, but if you're on Windows, you're making your own life harder by using UTF-8. Microsoft is migrating APIs to UTF-8 but it'll take years before that's finished. Just look at all the conversion code you need according to the page you linked.

Now, if you're writing a cross platform library, you'll have to decide what encoding(s) you use. I personally don't really see why you wouldn't make your library encoding agnostic, but if you want to stick to one single encoding, you'll have to decide.

If you're writing a program for Windows, technical superiority is a mediocre argument for making your own life that much harder. There are tons of formats and design decisions that may be technologically superior, but just end up wasting programmers' time, and this is one of them.
Exactly. I have reviewed a few articles for Nature Medicine, Nature Communications, and twice for Nature.

In many cases, I found really absurd causal claims, plus a total ignorance of confounding and causal inference techniques.

It is shocking that many researchers in biology and medicine have never heard about many of the topics surveyed in e.g. Chapter 36 of Kevin Murphy's second book [1].

It's pretty unlikely to cause an intoxicating effect: it's surrounded by the mouth, so it'll be taken up almost instantly. It never gets to accumulate, so I'd expect the impact is far less than even something like kombucha.

I wonder what the religious implications might be.
If so, I'm coming about to your point of view
Yeah, sure. A milliliter of etanol a month versus pain and drop of quality of life. Who would choose that!

It would certainly be a game changer for lower income families.

You are right that I was talking about delivering a first working version, not about tuning performance. It could be argued that optimizing for memory (de)allocation so early in the development is a case of premature optimization. Sadly, I don't know a (good) path from gc-based development to safe manual memory management, so I'll keep that counter-argument for the day I see one such path :)
There is this website, nngroup.com that used to be a popular reference on UX matters. They wrote lots of articles about how they tested using computers by mouse instead of keyboard and that mousing was loads better and had wide-ranging conclusions about UX from this. But the studies turned out to have actually been things like ‘replace all letter ‘e’s in this sentence with ‘|’ symbols’ and using the keyboard meant arrow keys and backspace rather than using a find-and-replace function. So sure, mice are better than cursor keys at selecting lots of letter ‘e’s and editing them, but one would hope that such a description is not representative of actual computer use and so not a good foundation on which to base general UX conclusions.

It is in this sense that I worry about the test scenario described being unrealistic. If one is measuring (and so implicitly optimising for) things that don’t matter, one is potentially rejecting solutions that would improve things that do matter without helping things that don’t.

More realistic scenarios could be:

- successfully format 10 lines or so of haskell into a hacker news comment. Obviously this is not relevant to most people but I give it as a more realistic scenario where typical mobile text-input mechanisms struggle.

- edit a misspelled name in an email of a few paragraphs.

- reorder two paragraphs in an email then edit for clarity.

- add full stops to a bulleted list (struggling with this right now).

I am sad that text editing on mobile is hard. But it does seem that efforts to make it better were not appreciated. My reading of the 3d-touch thing and other comments on this article is that the problem was appreciated by Apple but people didn’t particularly care[1] when Apple then dropped 3d-touch, for which improved text editing was its ‘killer app’.

[1] I have seen people complain about the loss of this online but I think the complaint is quite niche.
It seems that the synthetic stone is not the cause, but highlighting the problem: poor enforcement of safety standards and inadequate PPE provided to workers.

Just because there's more silica doesn't mean that it's suddenly unsafe whereas cutting granite is safe. Even drywall or cutting concrete you're supposed to wear PPE.

Medicare for the elderly, but we also have Medicaid for people in poverty (< $15k/yr income for a single person w/o a family) which covers most basic medical/dental/ vision needs and is taxpayer funded.

Someone taken out of the workforce may qualify for that if they don’t already qualify for disability insurance or similar payments (although I’m not 100% clear if those are funded via private disability insurance or public programs)

I think current course is to let IT companies set up presence in Liberland (for low taxes / less bureaucracy). I'm not sure how viable is that, given other governments are unlikely to recognize Liberland-registered legal entities at this point, thus disabling them from doing any actual business.

What's would be the purpose of such liberal experiment? I don't see what is there to learn about it. Allowing some entity to establish a government in your lands just to see what happens doesn't seem like a wise move to me. This would only legitimize their claims to the land and legitimize them as a sovereign state. It's a good way to end up losing this land and creating yet another microstate.

False dichotomy. Fasting does not mean you have to eat up until your final waking moments.

I do not consider my lifestyle fasting, though I rarely eat breakfast and typically have dinner 6-7pm. Which is ~6 hours before I go to bed.
