>I also saw people continue babysitting or au pair arrangements

I mean what I said. Where I live (Wales, UK), it was illegal to have people in your house (and obviously, that meant you also couldn't go into anyone else's house) until mid-2021. Obviously, we did not follow that law, as it was absurd and would have caused significant harm to me and those close to me.

Do not patronise me, by suggesting I should have "planned better" or "adjusted quicker". Saying such things is incredibly demeaning to the effort we did have to go to, to do our best as a family. Trust me, once I realised that no-one else was looking out for us, I did plenty to ensure that those closest to me would be ok (and mostly, that consisted of breaking newly-passed Covid laws, including the one I already mentioned. It was also illegal for me to go to our nearby woodland, because we were not allowed to leave the county we live in and I live in a city that is its own county.). I am proud to say that my two young kids will probably have no memory of Covid, and am very proud to say that we have also not succumbed to the new parenting norm of allowing kids of almost any age to spend as much time as they like staring at screens. In doing so, selfish pursuits like my cycling and other hobbies have had to take a back seat.
In my experience, if there's one thing missing in math pedagogy, it's that none of the math classes teach you how to think through and write proofs. I was personally fortunate that my high school math teachers made an effort, but that's not that common.

It'd be like if the first time you encountered the concept of an "essay" was when you took a history course in college. You'd have a rough time just understanding how to do the homework.
I can't solve your mystery, but your PC didn't get a slack notification while you hadn't yet booted the OS.

It's something else. That's too big of a conspiracy to be the answer.
Well it all depends on how much writing one does. OP estimates they have 1 year before they use too much of their drive’s endurance.

Be aware that on-disk hardware encryption should generally not be trusted. It is not auditable or trivially verifiable. Some years back there were some revelations that some drive firmware encryption was woefully deficient. So much so that whereas Windows previously would treat on-disk encryption as sufficient, Microsoft stopped relying on it entirely.
What. The. F
Another UChicago student here (former math major). I think the UChicago math department took education seriously in a unique way that I wish they got more credit for; the Inquiry-Based Learning classes, the summer classes for Chicago public school teachers, and the Research Experience for Undergraduates were all pretty special, I think.

Also, the math classes all had a shared policy of "you can work with anyone you like on a problem set, as long as everyone's name is listed on there when you hand it in." I loved that, and I did all my problem sets in groups while I was there, and I think I learned more because we were always explaining things to each other and arguing about solutions. I heard a rumor at one point that this policy was the direct product of Peter May's bad experience at Princeton, which required students to work alone when he was there.

TFA does seem like a pretty stinging indictment of Princeton's math department.
What was the most repressive aspect of being a Quaker? The Puritans were throwing people in jail, and they had that whole Rhode Island thing. (Did Rhode Island flounder?) The Dutch, I'm ignorant of.

Let's say you're a Quaker and you come over as an indentured servant in southeast Pennsylvania in the William Penn era. After your servitude is up, you get 50 acres and another 50 acres from William Penn and become a farmer. How much less repressive would your environment or your children's environment be if you weren't a Quaker? You're still a farmer, farming, who crossed the ocean to a new world to be an indentured servant. Did the non-Quakers slack off?
This wasn't the case for the company I worked at. It applied to everyone of every rank. Not as a title, but just a general descriptor used in place of "employee" or "personnel".

> In the end it seems to come down to one question everyone has to answer for themselves: Do you agree that advertising on the Internet should exist?

There are other questions. What is the evidence Facebook won't track as much as possible no matter how much browsers give them? Did advertising exist before this kind of tracking?
This left/right dichotomy has always been broken. How about a teleological spectrum assessment? I have beliefs that lie at the extremes of both ends, I've never been represented by either progressives or conservatives. It's such an obscenity that such polar thinking has persisted for so long. And especially considering the wide gamut of controversies we're capable of undertaking with the complications that science, economics, and the embrace of moral relativism on all scales has introduced into the organizational weave of our society, and the implications that the US has on the globe as the de facto world sovereign. At an individual level we're all morally culpable for the wrongs our society commits, and the first step to engaging that is allowing people to give meaning to politics to reawaken political consciousness, and the way to do it is to give people a higher degree of autonomy over their environment, and attribute them with the responsibility of determining the direction we had ought to take.

Another gripe I have is academia. You ship the bulk of "educated" people from one institution to the next, and they're wholly clueless as to how the world actually works when they finally get out, but they have all the pretensions that they've got a clue. My friend, a Pharm.D., chatting about business exposed his naivety to me and another friend, whinging about how some minutiae got its corners cut, and general incompetence. This is stuff me and my partner had been exposed to since we exited high school. Whats worse is this pattern is almost certainly occurring inside the institutions themselves, where kids never having been met with the real world are shoehorned through programs and eventually given license to teach. It comes to mind that a large proportion of these people are living inside a bubble where theory is practice. Yes, it's a generalization, but from my own first-hand I think it does possess a kernel of truth.

"it is important that those who are not vaccinated get their vaccine immediately."

Sounds like another biased article to promote experimental vaccines. Curiously right after so many studies about increased hear failures, myocarditis and pericarditis in healthy population and dying athletes in front of the cameras.

Absolutely we do!
For example, garbage collectors are complex beasts that are hard to tune and tough to scale. But of course some OOP languages have started using GC anyway, in which case, I honestly believe they might as well be functional programmers :)
Donations are pretty heavily concentrated in New York City and they have a hard time collecting from other areas.

As for cord blood banking, anyone who can get a kit (which should be everyone because we ship nationally) should be able to bank, but in the rare cases that doctors push back, you can request that they put in your medical record that they are refusing, and usually they will reconsider because - inversely -they don't want to take on the liability of not banking haha
Funny you mention that. From my earlier comment, I run a lit zine, and we get tons of that stuff.

Our journal explicitly rejects 99% of those submissions, just to stand out from the pack.
In the past I'd eyeroll at $100 for some index cards, as something for the 20s/single/300k programmer crowd. But these look great I have to admit its tempting. I like 2 or 3 things on my desk MAX and it does matter those things are pleasing to look at 14 hours a day.

Computer programming is applied formal logic. No, really, it is. I'm completely serious.
I think there is a lot of leverage in the crypto space, I don't think there is much contagion to the other financial system, yet.
I'm not sure that's the lesson, based on this post, it sounds like the institutions were vital to the prosperity more than the growth. In a sense, growth is prosperity, but both were the result of institutions, and I'm not sure that growth was necessary for the maintenance of the institutions. I think the big takeaway is that people thought of the institutions are sort of an immutable fact of the world, when in reality, they were very break-able. Though that is also a sobering thought exercise as well.

> They’re actually both right-wing by global standards

The center-right wing of the Democratic Party is. The leftmost wing, the AOC side, is center left.

> Furthermore the binary status quo appears as manufactured tribalism to keep the American masses busy with minute shades of policy difference

This is a very popular take right now, has been for decades among young people, and it is absolutely wrong. Ask any woman or person of color or LGBT+ person. Ask those of us who lived through the 2000 election and 9/11.

Also, the Republican Party's official policy position at this point is whatever Trump says, so even assigning them a place on the right/left spectrum is probably a category error. They want the USA ruled by a weak, incompetent dictator.

I'm curious about the actual volume of literary work being produced compared to days past. For those who still partake: is the work still being produced? Is it harder or easier to find? Is the quality changing?

There is no lack of work being produced. My wife (a writer) subscribes to several literary magazines, none of which are associated with a college or university. These journals seem to be doing just fine, between subscriptions and grants. And she is always receiving information about newer journals, or journals that we've not come across before.

Randomness plays a large role. That's why the FAQ says a small number of reposts is ok if a story hasn't had significant attention yet (https://news.ycombinator.com/newsfaq.html. We want good stories to get multiple cracks at the bat.

For best results, it's important not to just post and repost your own stuff though. If you do that, our software will start interpreting your account history as promotional and will start enforcing this guideline: "Please don't use HN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity." (https://news.ycombinator.com/newsguidelines.html)

It's best to build up a track record of interesting submissions from unrelated sources, and to intersperse your own articles with those. If you dig up interesting things from a variety of places, things people haven't run into before, then you'll be perceived as a community contributor rather than someone trying to market something. Particularly good are stories on out-of-the-way topics that rarely or never get attention. The best submissions are the ones that can't be predicted from any existing sequence (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...).
I also like that I can prioritize things by sticking them to my laptop next to the trackpad. Important notes that need to follow me away from the desk often get stuck there.
Just to clarify - ublock origin is going to continue working the same way... right?
Sibling comments have effectively pointed this out, but obviously it could be optimal per tag, and also given we already have Find My Friends access to each other it’s a completely meaningless objection.

Point is it should be at minimum opt-in possible because without it it clearly misses the obvious connection to a selling point of Apple (family sharing).

The multiple packets on deposit is actually a marketing tactic haha. There's a lot of chatter about using 2 vs. 5 compartments (our lab uses 5), but in reality, they are 2 large compartments or 5 small ones and people will generally use as many stem cells as they can if an emergency health situation comes about.

We're different because 1. pricing - we offer monthly payments (we have offered annual upon request). When you add up all banks' costs to cover 20 years, we are the cheapest option. 2. We process stem cells manually (by hand), which can yield up to 25% more stem cells than if they are processed with a machine/automatically. Our brand is built around evidence-based personalization. 3. We offer placenta banking, which requires a more advanced lab that we have access to. 4. We have a brand and community behind us. Many parents tell us that they choose us over other banks because we have such personal customer service where everyone feels educated walking into the process of banking and they feel comfort walking out of the process of banking.
I will put this opinion here, as my political affiliation can best be described as "Mean Tweets Nostalgia."

For two decades, the complaint from "the right" has not been media bias, but media agenda. This terminology has been widespread in circles that most here would never have considered, and I believe it is telling this distinction is not made in the article.

There is a distinct difference between even editorializing vs reporting and that of media control of "narrative," a term anyone who has a liberal arts degree knows is something distinct from the idyllic "just the facts" view of journalism.

Post-Woodward & Bernstein and the mythos surrounding that event, the journalistic class took it upon themselves to be agents of social change. This idea that neutrality shouldn't be approached, and that journalism as a class were supposed to be agents of change, created the forcing function for the rise of Fox News in the first place. And that's where we are now: a world where Dan Rather can make Times New Roman printed pages and act like it was historical documents, Journolist can induce "epistemic closure" amongst hundreds of journalists, and where an entire social class can feel empowered to shut down speech of which they are critical. (The publication that broke the Journolist scandal was founded by someone who is now quite famous, and it mirrors the reaction indicated in the article.)

Narrative, a euphemism for agenda, is the core distinction driving this conflict. It is also deeply imbued in the soft postmodernist philosophy encountered by the (well-off) journalist and tech class now in power. Until narrative goes, the brief period of respect for facts will not recover, and we'll have the norm that has been American press for most time: yellow journalism.

That’s true, but the alternative is no vote at all.
> I will not specifically call out names, but the some of the largest and most well known consultancies do this as a matter of practice after they overbook themselves for projects for which they do not have staff on the bench to fill.

Infosys, TCS & Accenture comes up immediately to my mind.

There are hardworking people in these companies no doubt. Many times it gives an opportunity to the less fortunate as well. In general, however their workforces are poorly trained & business practices borderline unethical (The good ones quickly leave). These companies pay peanuts to their employees, and most of the latter are sticking for the promise of an onsite deployment. There are horrid tales of client having to lock horns with the TCS/Infosys service manager to get the contracted job done.

Case in point: managers at a Japanese giant are shaking their head in frustration since they are locked-in to a Infosys contract. No way they can shake them off due to poor project documentation & shaky installations which require heavy service & maintenance. Choosing an alternative would bring in a tidal wave of expenses, so keeping the status quo. It is deeply unfortunate that they bill their clients higher for the same shoddy work culture as the number of years roll-by. I assume this will continue as long as the cost of renegotiated contracts are lesser than switching to a different firm, or the tech stack is rewritten for a newer project.
I definitely did things as a teenager that were dangerous, unnecessary, detrimental to my physical or mental health, etc. etc. I don't have kids, but I would probably make some effort to dissuade my kids from doing the same things I did. How do you approach that, without heavy surveillance? Did you just get lucky with good kids? Is having conversations about it enough?
Anti-fingerprinting will never be bulletproof. Legislation definitely needs to be part of the solution.

More generally, though, I have to ask: do we want an ever-escalating arms race or a negotiated peace?
1. Might be also nice to handle 0-0 case separately and grey out all those letters both in the guesses on the board and perhaps in a separate keyboard as well.

2. Can go one step further, e.g. if a guess has X-0 and all there's only X cells that are not greyed out (see above), mark them as green in all correct guesses on board.

3. After these two steps, step 1 can be applied again since there will be more such cases where it can be applied.

You might argue that it steals from the game, but I'd disagree - it leaves the high level strategy to the player while saving them from dealing with the boilerplate. A very good example of that is Good Sudoku game (app), where they've tried to innovate on classic sudoku interface for similar purposes - I highly recommend checking it out since it's somewhat close to this game in some regards.

I agree that that appears to be bullshit. When I think back to my courses, I had one in ‘vectors and matrices’ which is roughly equivalent to early courses in what American universities call ‘Linear Algebra’. I think it included:

- a refresher on matrix multiplication and eigenvectors/eigenvalues for those who hadn’t learned them in high school

- inverting arbitrary matricies (done with the horrific formalism and rigour that first year undergraduates sometimes like to see)

- basis transformations

- special matrices (orthogonal, unitary, hermitian, etc)

- suffix notation (by far the best bit)

- bilinear/quadratic/sesquilinear forms

- tensor products/contractions/basis changes (but without using tensor notation—it was all done with suffix notation thankfully)

And an exam question might be like:

- invert or diagonalise a 3x3 matrix of nice numbers. Or do Gaussian elimination to a 4x4. (These would be warm-up/small questions). If you get eigenvalues, maybe make a geometric interpretation.

- do some algebra with some variables known to be some kind of special matrix to prove something. (I.e. apply a property of the special kind of matrix to do the algebra)

- do some suffix notation algebra (in particular using some kronecker deltas or antisymmetric tensors and associated identities)

- something about bilinear/quadratic/sesquilinear forms/algebra

They mostly tried to avoid bullshit exam questions that were just computation. There were some other opportunities to do a bit of matrix computation like solving/linearising/sketching certain ODE systems, or computing Jacobians.

In second year we had a course that was actually called ‘Linear Algebra’ which touched on (numeric) vectors and matrices but mostly talked about linear maps, had lines of juxtaposed symbols with juxtapositions having different meanings between different symbols, and mostly involved statements like ‘let V be a vector space over F and let e_1,e_2,…,e_n be a basis for V’. I think the exams did not involve any computation and maybe involved producing some of the proofs from the course or applying them to something.
It's something you learn in middle school or high school math. Pretty good bet that a college freshman would be familiar with it.
My mind exploded. I played that game on my first computer, a 286. I think it was the first game I owned, it came in a pack with Silent Hunter I think, maybe Panzer General and another game I don't remember...
I think that low downside could be a useful company-screening mechanism. Any company who takes that as a negative would probably be somewhere with a poor engineering culture that I wouldn't want to work at. Could certainly be neutral or an eyeroll at some good places, but I'd guess anyone who counts it against an applicant probably isn't a great place to work.

They could focus on user needs. Having an ad-blocker by default would be a good start. Figuring out how to remove advertisers and the incentive to advertise (and thus SEO spam etc.) from the internet is a goal I would support.
It's really interesting when you look at the UK system. Here we have former polytechnic universities that are equivalent to US community colleges and are more teaching focussed. Then you have your red brick and Russell group universities that are research focussed and where the teaching is often a bit shoddy as the academics see it as a distraction. Finally you have Oxford and Cambridge, which are very research focussed, the two most prestigious universities in the country, and also have a very intensive form of 2 or 3 to 1 tutorial teaching that is generally highly regarded, even if it does come perilously close to spoon feeding sometimes. So you can have high quality teaching at research focussed universities, but it certainly doesn't seem to be the norm.
I'm more and more convinced that the research and teaching sides of a university should be separated out at this point for most subjects, at least for undergrads.
