I see this even with adults. You can certainly toughen up and work long hours and maybe even efficiently. Most people will probably do a better job with less than ~ 6 hours per day at least on intellectual work or learning. If you try to do more you will not be able to sustain it long term with your other obligations in life while staying healthy and happy. As with anything, there are exceptions but they tend to confirm the experience.
I have worked more than 12 hours more days in a row on very hard stuff during e.g. infrastructure migrations that didn't exactly follow a plan for unforeseen reasons and I did an exam the next day after the return from this business trip. I had more similar experiences. I am able to script/ program multiple hours without much in terms of break if I am "in the flow". I also like long walks or just sitting down with people drinking tea and having a conversation even about somewhat deep topics. This is a kind of offset of the peak concentration and performance.

The question about energy and motivation is in my opinion also related to tools and methods and not just long hours and early wake up. At OrgPad.com we learn about new approaches to education in conversations with our users and friends all the time since our 2000+ users are mostly students at elementary schools, high schools and universities. We also have a small but very active community of academics using OrgPad to pursue research and personal development. E.g. a teacher created a large OrgPage with many topics related to chocolate. These are roughly: activities, knowledge gathering tasks or experiments and information. Using this approach you can motivate children and their due to COVID-19 involuntary home schooling parents to discover e.g. whether chocolatey burns: https://www.orgpad.com/s/9l8igw
The teacher who made all that shares her experiences (in Czech) on https://www.youtube.com/watch?v=nyM6l4FHtb0&list=PLs5kSDmhaz...
It seems, the children (and their parents hopefully too) like her approach to digital education a lot. I sincerely think OrgPad.com can help many people with organizing their thoughts and other information and related materials while not sucking their mental energy as other tools and methods do. If you want a short (< 3 minute, in English) taste of what is possible with OrgPad, please have a look here: https://www.youtube.com/watch?v=FtqFWSJT9yw
> In answer, maybe no harm is actually done. But even so, people will perceive that they have been harmed.

Maybe cows can fly. Maybe a lot of things. But it does cause harm. So your idea about people's perceptions seems condescending
Agreed, the difference between "real" CO2 meters and consumer CO2 meters is really stark. Given that you can get nitrogen and CO2 in tanks, I expect one could build a calibration setup with a fixed volume tank, two metered gas ports, and some software. Start by purging the tank with nitrogen, then add CO2 for the 400ppm baseline. Calibrate there, then add increments of 100ppm (or 50ppm) CO2 and record the readings up to say 1500ppm total. Then you have a calibration table for that meter that will let you translate from its indicated ppm to the real ppm.

I felt I was progressing your point. You can't answer if a program is portable based solely on the language.
One could alternatively describe it more as a rebranding of thunderbolt multiplexing layer.

For those unfamiliar: USB4 does not specify how to interface with specific non-host devices like USB 3 and older did.

Instead it is a multi-protocol tunneling (think multiplexing with routing) system, that allows tunneling USB3.2, Display Port, and optionally PCI-E (i.e. what thunderbolt is known for). It also specifies a requirement of support for different alternate modes, like display-port alternate mode (non-tunneled), and optionally thunderbolt 3 alternate mode. (Thunderbolt 3 runs at a different rate than USB4, among a small list of other differences, not counting the additional features specified in USB4).

Hubs are required to support the otherwise optional thunderbolt 3 alternate mode and USB4 tunneled PCI-E, thereby making every USB4 hub a valid Thunderbolt hub, both for classic thunderbolt (TB3), and for USB4-based thunderbolt (i.e. using PCI-E tunneling in USB4, which I assume part of the updates made in TB4)

Hubs will also support plain USB 3.X from a host, since USB4 is just a negotiated alternate mode over USB3. Thus USB3 can be used unencapsulated if only the hub supports USB4; Fully encapsulated if Host, hub, and device all support USB4; or partially encapsulated, like if the host and hub support USB4, but one of the downstream devices only supports USB3. The hub becomes responsible for encapsulating/unencapulating the tunneled USB3.

In a similar way, a hub can support connecting a classic thunderbolt (TB3) device to a hypothetical host that only supports USB4 PCI-E encapsulation. The upstream port and downstream ports are independent, so one can use the TB3 data rate while the other can use USB4, and the hubs are required to pass the PCI-E data through a PCI-E switch, so everything just works. (Especially since talking TB3 is deliberately nearly the same as talking USB4, other than link speed).

Obviously, USB2 is of course supported as well, in parallel to all other modes since it has separate data lines.

But USB4 is not all perfect. For example every USB4 port on a host must support display-port output. That is not really a huge problem on say a laptop, but it is a pain on enthusiast PC building, since it means motherboards will need a display-port passthrough socket in order to support that requirement. And undoubtedly there are or will be many non-compliant devices out there that break the whole intended it-just-works approach.
I think that there are two tests. First there is a non invasive test that can be done to evaluate if the foetus is "at risk" of Downs. Then there is a sampling one that is very specific. Basically counting the chromosomes. But the catch is that the specific test carries a risk to the pregnancy - so it's not applied without cause. As well as the sensitivity issue in the article there is also a specificity issue.

My daughter was tested (non invasively) as at high risk of downs (the doctor said 50/50) we decided we didn't care... lo and behold: she doesn't have downs. I don't know enough about the area to make judgements, but I am definitely concerned that it's not a slamdunk that the doctors are getting this right.

There is a huge agenda of control around pregnancy in the UK - our consultant was so arsey about us not doing the follow-up that I had to get him changed out (it later turned out that he was struck off 2 years later for more or less murdering a woman and child, but that's another story).
My habit, when I'm playing with a new language, or other command-line-friendly gadget, is to spin up a new GNU/Linux VM on a cloud somewhere, dabble on there, then delete the VM once I'm done. If I've got any files worth keeping I put them on GitHub.

Don't have to worry about filling my own machine with rubbish, I can load the VM without it impacting my own machine, and I can generally be fearless (and incautious) in the knowledge the machine is of no real consequence. It's also a good way to try out an unfamiliar distro, or an unfamiliar Unix.

And also with cloud computing. It's a good excuse to play about with EC2 firewalls, for instance.
> You make good points and I've learned something about PWA's, thanks. You also acknowledge that it's in Apple's interest to push native, which is absolutely true. The only thing I would disagree with is that you think "Apple just needs to give PWA developers [...]" when Apple does not "need" to do such a thing at all.

Your whole comment is predicated on the interpretation of one word. Apple just needs to support push notifications for PWAs if they want to make PWAs useful and competitive, and it would be helpful for Apple in the antitrust battles that they seem to be facing. That's what I meant by "need". Previously, Apple also needed to add offline support, but they eventually did... so now that isn't a "need" for PWAs to be useful and competitive, even if Apple's offline support for PWAs is limited.

Apple doesn't "need" to implement it from whatever abstract interpretation of the word "need" that you're using... I'm not saying Apple will starve to death if they don't implement it -- it isn't a fundamental business "need" that they currently have.

They should do it, and I really want them to do it.
NK is barely surviving. They don’t have enough ammunition and fuel for a full blown war. They don’t care about religion or doctrine. They are not trying to spread communism. They have no delusions they can take the Korean Peninsula.

Without anything motivating themselves besides just trying to survive, the motivation of everyone to fight is very low. That doesn’t make for a good dedicated army. Most NK soldiers would surrender as soon as they could.
I'm afraid a lot of what you've said here is simply not true - it's either wofully outdated, or pure disinformation. Attitudes to Down's have changed a lot in recent decades, and children now get access to education and assistance, instead of being stuck in an institution to rot. As such, life outcomes are vastly different to what they used to be.

I have a daughter with Down's, so I probably know more about it that most.

> You will never surpass the cognitive capacity of a young child

This is just completely untrue.

> you will have impaired vision and hearing

There is certainly a higher incidence of vision and hearing problems in people with Down's, but it's far from guaranteed. Further more, glasses and hearing aids are a thing.

> if you ever manage to speak at all

I'm struggling to take you seriously now - this is utterly absurd.

> You will have a myriad other chronic and painful health problems

There is a higher incidence of some physical and mental illnesses in people with Down's, but again, it's far from guaranteed, and again need not have a large impact. For example, a lot of those born with Down's have a small hole in their heart, but nowadays it's fairly easily rectified. Not sure what "painful" health problems you could be referring to.
I'm not obligated to do many things. I do however wear a mask because it is the right thing to do. This isn't a moral dilemma.
It's much, much, less likely. Half of women with down syndrome are infertile. If they do get pregnant they usually end with a miscarriage and there is a 50% chance the syndrome won't be passed down.

Homosapiens are a result of chromosomal fusion, so I would approach the claim of "accruing defects" with great skepticism. Nature is still selecting as evidence by inflicting a high miscarriage & infertility rate.

If bringing down processing costs is the issue, Apple just did that.

Allowing multiple stores would increase costs doe small developers, because of the overhead of dealing with many stores and many sets of rules.

Any cost saving would disappear into one or two levels of middlemen, otherwise known as publishing companies.
Maybe subconsciously. I wish I could give my brain credit for it.
Apple already has a huge gaming platform with iDevices and the app store. Mobile games are a huge business and Apple takes 30% of that revenue.

So why would an energy efficient ARM chip suddenly make a gaming console of interest to Apple? Both Playstation and Xbox are X86 PC hardware. Apple could have just used x86 years earlier, but they didn't. Why? Because that's not their market.

Sales of consoles are driven by price, and the game portfolio. I have yet to meet a consumer who will be excited for a energy efficient console which costs more than the competitors and have almost no big titles.
The Usability of Ownership
You're right; but all too often companies turn to government to pass laws weakening unions, rather than continue to negotiate in good faith.
Google search has dropped so much in quality, that it's almost down to where it was before I switched to it. Altavista, Dogpile, InktoMe are no more, alas... I guess I'm going to have to use Bing or Yandex fairly soon if the trend continues.
I am not seeing the benefit of this vs. a traditional internship. If there is someone is pitched as a potential hire, I have higher expectations vs. someone who is pitched as an intern. I know we will need to train up interns - that is the whole point. But to fill an open role on the team, these folks will be compared with every other applicant, and odds are we will choose someone who we know can hit the ground running and contribute.

The term "Fellow" also reminds me of the title given to the top engineers in large established companies - it implies they are the cream of the crop from the entire industry, not a recent bootcamp grad.

In short, I'd just call this an internship to avoid setting incorrect expectations.
You can’t? What if there is a measurable economical advantage for you? If you’re super inexperienced these four weeks unpaid internship might be way more valuable long term than four weeks sitting on a couch writing job applications with a near-empty CV.
Seriously.

I've seen several families destroyed by the challenges involved in raising children with special needs, or rare diseases.

Having a nuero/genetically-typical child is a challenging full time job. Add in the prospect of it being a full triple-time job for their entire life, whether that's six years or 130 years and it's not likely to be remotely possible for the vast majority of families to sustain. Between the mandatory extra time commitments, lost pay, increased expenses, and the conversation changes. How could it not?
The families that I know that have chosen to abort a fetus with Down's syndrome have all gone on to have additional children. Although we can't say for sure, had those families chosen not to abort, those additional children may not have been conceived or born. It seems somewhat contradictory to put a huge value on the potential life of an unborn fetus with Down's while not recognizing the second-order effects on those potential lives.
Ask HN: What are some small, internet products/services that you wish existed?
The title is fairly self-explanatory. What are some small, internet products/services that you wish existed? Could be a website, app, or even a library/framework.
I've started using an equivalent pattern and my implementation has generally been a success, so I'll share:

My email body has everything the "optimal" reader (i.e., someone who is already familiar with the topic item) needs to |action_verb| regarding what I've written.

Then I "conclude" with my usual sign-off (e.g., Cheers, [CRLF] "/Aceyman").

BELOW that—but above my default signature/contact info block—I place all the deeper-dive / expository / rationalization narrative which provides that level of detail for anyone who needs more than my main body provides.

I've been using this pattern for about a year or so with good results.

/Acey

At the start of the supplementary section—and depending on the topic & audience—I'll sometimes use the 'section title' Extra-credit reading, because everyone loves a chance for some extra-credit, right? That's my little psych ploy to entice readers to take a look at the nominally 'optional' expository stuff.
There are non-public-domain ebooks out there without DRM. Kobo sells some, for example, though you have to check the format before purchasing since they aren't all DRM-free. Libreture has an extensive list of DRM-free ebook shops[1].

It depends entirely on the person what sort of effects Downs Syndrome will have on their life. Some people born with Downs Syndrome have fairly mild intellectual disability and so are capable of basic life independence and holding down menial jobs, however many people will have moderate to severe intellectual disability and be completely incapable of living independently at any point in their life.

I think many people don't understand the depth of that statement, "living independently" isn't just a matter of financial independence. Certainly there is a place where society could help to fund the living expenses of the severely disabled. What I mean is that many people with Downs Syndrome are unable to perform basic tasks of life without assistance, such as maintaining their living space, cooking for themselves, being able to get to a doctor's appointment on time, being able to pay bills. Note, I don't mean forgetting to pay bills, which can be resolved through assistive technology, I mean being unable to follow the process to actually make a payment.

The life expectancy of people with Downs Syndrome has become quite good, and is around 60 years of age now, and yet for many of these people they will never know a moment of true independence and agency in their entire lives. They will need a permanent, likely live-in, caretaker from birth until death, long after their parents have passed away.

One unfortunate reality is a prenatal test can't tell you how severe the disorder might be. Your child-to-be could end up being one of the kids with Downs Syndrome who effectively has some physical abnormalities which can be accommodated and is a little slower at learning, but could otherwise graduate college and live a normal life. Or they could end up being one of the many children with Downs Syndrome that suffers from a deeper intellectual disability. IQ is one of those things that's mostly meaningless, but on the extremes it matters. The average IQ for adults with Downs Syndrome is 50, meaning that for most people with this disorder they will never get beyond the intellectual capacities of a small child. Some, unfortunately, are mostly non-verbal and unable to carry on conversation.

I don't think I should be any more specific than that, because it wouldn't be fair to the privacy of the people I've volunteered with. If you're legitimately curious, I'd encourage you to just search online. There's a lot of information about Downs Syndrome care out there.
You couldn't assume that before.

Some black people don't care about this kind of thing. Some do.

I don't think this answered the OP's question. I get that you're arguing that the student is the primary beneficiary of the free labor they are giving to the company - but I'd be suspicious that a court would allow this interpretation.

At worst this allows for negative cost labor where an employee pays/borrows money in order to provide value to an employer.

To the direct question - do you provide appropriate indemnity clauses protecting employers should the legality of the arrangement be called into question?

I've seen the exact same scenario play out with an e-commerce site using MySQL.
Did you come here to just poke fun at "old" people or is there actually an issue because if there is an issue you seem much more focused on how "old" and "unsavvy" these people rather are than on resolving the issue.

If there actually is an issue and a meeting I'm beginning to think that they are actually just looking for a pretext to fire you, likely because they can tell you think they are old luddites.
I'm Polish, for the entirety of my childhood and teenage years the man was revered more than Jesus himself. In Poland he's beyond Saint, you can't speak ill of him. And yes, I'm aware of his contribution to the fall of communism and fall of communism in Poland in particular - his election as a Pole was specifically designed to achieve that goal after all, communist government really didn't know what to do about it and it strengthened the Polish church to such an incredible force they became completely untouchable and yes, could be seen as the leading reason for the eventual fall of communism.

However.

Despite the early life reverence, I feel that as a grown adult I do now see him in a completely different light - as a man put into a certain role which he has played correctly, and ultimately he has protected an institution that sheltered abusers, corruption, wealth and which ultimately is a cancer spreading over Poland right now, destroying the society from within.

Also not everything is about US - look what's happening in Poland with cardinal Dziwisz, the closest confidant of the pope - I always suspected he was a piece of shit after disobeying the direct testament of JP2 and making money off of it, but now it's been confirmed he's much much worse than just profiteering off a dead pope.
Specifically, whether it's locked in any way, preventing alternative operating systems.

Upon second reading it appears I have misunderstood your comment. My bad!
You are probably not aware of the fact that majority of Down sufferers cannot procreate. There is only a few recorded instances of Down sufferers having children.

That said, you can have mosaic aneuploidy (just some cells are affected), in that case, your life is likely to be more typical.
Show HN: I made an app that lets you trade your books with anyone in the USA
I made this app called Biblo. Here's the problem I solved for myself and hopefully for others:

Problem:
After going down the rabbit hole of personal development a few years back, I found myself picking up hundreds of self-help/business books in hopes of becoming a better version of myself. One book after the other my bookshelf became overwhelmed. I wanted to read more, but I couldn't fit another book.

Solution:
I started to notice that books I've already read just sat on my shelves collecting dust for months. I could donate them to a local thrift store, but what if I could exchange them for books that I wanted to read. That's when the idea for Biblo came to mind. I knew I most likely won't ever read them again so why not trade my book with another reader for a book that I want to read. This way, I won't exceed my book limit and I could continue to read topics I'm interested in. A classic win-win situation .

Why Use Biblo:
- It's simple to get started. Just swipe left or right on available books
- Never buy another book again. Books can cost up to $25 which add up to large amounts overtime. By using Biblo, the cost of acquiring a new book is about ~$4 (the cost to ship your book). That means that for every new book you could have bought at your local book store, you can trade 6+ books on Biblo
- Save money on books
- Save the trees
