Thank you so much! Agree with you that the direct question answering on mobile fits nicely. We appreciate the feedback on adding a feature to limit the results based on a time range, it's a good idea and I can see a lot of use cases for that.
> Sure, nuclear will run out much faster than the sun. But that "much faster" is still on the order of magnitude as the age of human civilization.

Not with what we actually know how to economically recover, AFAIK, though sources vary widely on such figures.

And yes, pumped storage takes a long time to build, but that is not a disadvantage compared to nuclear plants, as you note. Expanding transmission infrastructure also falls under the line of boring things we know how to do, if the political will is there. I am mostly just pointing out that while both require massive infrastructure investments, making nuclear truly sustainable relies essentially on speculative research in a way that solar + pumped storage does not. Plus, nuclear has other advantages (like being usable in deep space, under the ocean, etc.), which makes it feel a little wasteful to use for power generation on a planet bathed in sunlight. So I don't really understand the strong preference for nuclear that a lot of people seem to espouse.
In general an algebraic (polynomial) functor which is also a monad is called an operad (non-sigma operad for the algebraic topologists). They are plenty and have a lot of interesting structure.
*-T1 Ethernet was designed by Broadcom and the car manufacturers to implement single pair ethernet for automotive applications. Specifically for things like backup cameras, ADAS, etc. The standard is less than 10 years old and has nothing to do with 10base-T.

https://en.wikipedia.org/wiki/BroadR-Reach

100Base-T1 has more in common with 1000BASE-T than the legacy standards, imagine if you took a single pair from the 4 needed to do Gigabit.
Seems like there's a few options. It could all be a bluff, or Russia might already know, or they know part and some part is fake to cause them to overreact, or some part of it is cover for some other way they're getting info. Or it's a double-bluff and it really is mostly or completely true and the intent is to get Russia to disregard it.
Slightly disingenuous to say I spent thousands on Halo specifically, but I used to run LANs/tournaments, so at one point or another I've owned multiple copies of every installation in the series, bought multiple of the same consoles for the sole purpose of those events, combined with controllers, etc.
The man is functionally illiterate so it's likely someone else did it in his name.
> this is part of why I live in Europe where university students in general are seen as an investment by the state and not so much a business to be optimised

In this specific case, though, I don't think these two things are in conflict at all. By selecting the best candidates on the basis of merit, MIT is doing what's best for both MIT as well as the broader society.

We all benefit from living in a country that produces top-tier scientists and engineers, and MIT benefits from being a place that is known for producing top-tier scientists and engineers.
I don't disagree, but I'd more specifically say "society has democratically agreed to upvote news they want to hear and downvote news they don't, with little to no concern/consideration for how accurate or true it is."

HN community is among the better at this IMHO, but it still happens here quite a bit true. The good news is, over the course of a few hours to a day or so it usually balances/corrects itself and ends up in a good state, but sometimes not before true but hard truth comments are killed and resurrected by vouches.

As I think about it, maybe the correlation is more with reaction time? The rapid downvotes tend to early and often, so it could be that people who vote on feelings are also the ones to react very quickly? Interesting to think about
>it follows that social mobility is pretty much dead. It is a bleak vision.

I have always found the idea of social mobility depressing. It assumes that we will always have a hierarchy, with some people who are powerful and prestigious and others who are poor and always feel inadequate. It assumes that we will always have an underclass but at least people can leave it.
Thank you very much for your participation and your feedback.

Question 7 and 8 "only" help us to know which practices and/or methods are in use in software development. The remaining questionnaire is independent of any buzzwords or if you are using a practice exactly right out of the textbook.

Thank you again for your participation. If you haven't finished yet you can continue where left by opening the link again.
Did the price of meat double over the past year? You have a source for this? All my googling of "meat price over time" suggests the price of meat did not double in the last year. Or even the last 10 years.
In these discussions about ADTs, often I see Maybe and Either identified as an ADT rather than an ADT constructor. Am I just missing something other folks 'just know'? If so, what's the intuition I should be looking for?
I finished the SAT early, and used the extra time to go back to the beginning and verify each answer. More time wouldn't have done much. If you can answer the questions, there's enough time to complete the test.
this should probably have been pitched to health insurance orgs.
> So much for that common, popular notion that standardized tests do not predict anything of value.

To people with a particular agenda -- that society will be improved if equal outcomes are mandated -- I suppose standardized tests aren't "valuable" to them.

I am very grateful for the SAT. I wasn't a good student. I was unable to do any work outside of school because of a bad home (my brother did hours long "hand-clapping/stimming" and chanting rituals, my mother drank, and my father was violent). But I did well on the SAT -- enough to get a national merit scholarship and a scholarship from Hofstra University where I got my BA in Math in the early 80s.

If it wasn't for the SAT I don't know what I would have done. Standardized tests are the only answer, and I was very upset when I read of schools getting rid of using them for admission.

SATs are also a great predictor of a person's ability to complete college. That was one of their original uses. So without SATs, you'll get more people doing poorly, and more people with no degrees and a lot of debt. And if these people are members of what's considered an "under-represented minority" then there will be even more remedial action required elsewhere to fix the problem of the high failure rate (like giving them degrees anyway, etc).
They're missing because everyone was poor and miserable back then.
Bankers where ultimately using other peoples money to issue loans so they didn’t care if the information was accurate and therefore not only didn’t check but actively falsified the information themselves.

That’s how you get this kind of crap: “How much do you make? It varies, I made 50k last year. That’s going to be a little tough, hmm let’s say next year went well, how much could you make? I don’t know 60-70k. Great 70k is going to make this all very smooth.”

The applicant assumes he’s being clear when getting a loan from the company he’s talking to. Meanwhile the company is only interested in selling Fake AAA bonds and just needs warm bodies to sign some paperwork.
There are other groups too. Like Big Rich Daddy who wants his kid to go to Yale as a legacy but he only has a 26 ACT and has only donated like $1m. When test scores are required, top schools basically have a “budget” of 25% of their student body they can admit with any score without it adversely affecting college rankings. Making tests optional makes it easier to admit more students that don’t “meet the bar” otherwise, since they don’t count against the 25% quota.
> high-level math students have very few opportunities to demonstrate their knowledge using a standardized metric.

AP math and physics exams? Or IB?

True that these are not accessible to everyone though..
That's a good example actually. I've never seen a Chipotle restaurant in my life but still know about them.
Can we somehow blame this on oppression?
The gotchas are answers that match common student mistakes.

What I'd do is solve the problem without looking at the answers so they wouldn't bias me. Then look for a match of mine with one of the answers.
> Doesn't most of Europe also rely on standardized testing for university admissions?

They sure do. So does India. In fact, a lot of other countries rely on testing a whole lot more than the U.S. which has interviews, essays, sports, teacher recommendations, etc.
My instant moral judgement on your having taken tests for others dissipated fully upon learning that they paid you in beer.

I will smile all day thinking about this.
I think the biggest issue there would be financing. Most fertilizer terms are COD but you don't realize any cash in farming until you deliver the crop (and for some crops, payment terms aren't great).

I think there could be a situation where individual farmers just can't finance enough fertilizer. The whole business runs on cash flow and it's tough in normal times.
Your switches and all client devices would have to have 10Gbps+ NICs/be 10Gbps+ capable.

"Are you talking about the notion that OO is about making an ontology, and that recapitulating a poorly-thought-out subset of the Dewey Decimal System in your codebase will somehow make it easier to reason about and extend?"

I'm referring to the origin of OO in Simula, a language for writing simulations. From that early OO had an extremely strong bias in favor of modelling "domain objects". In that model of OO, having an "iterator" class is actively wrong, because there's no physical corresponding to an object. That's where the Car/Engine/Tires example comes from, and to a lesser extent the Animal/Mammal/Cow etc. examples.

It's been 25 years or so, but I think when I took my software engineering class I was actively told my OO should model real things.

The irony is that I think OO shines most brightly in the abstract machinery of programming like iterators and other machinery like that. It has problems when you try to connect it to the real world by "exporting" the purely internal state changes out to something real. This is a general problem in software and it's not like I have perfect solution, but the OO tools tend to not be anywhere near as helpful here. (By that I mean, yes, we write the code that does this in an OO context, but inheritance/private/public/etc. isn't really that helpful in terms of keeping a particular variable in your object in sync with the database value it's supposed to reflect, for instance.) Simula somewhat deceived the early practitioners, because in Simula, state changes within the object are the desired outcome; when your Engine object flips its On flag from false to true, the object's job is done. This does not necessarily translate into the real world anywhere near as well.

And yes, goto is definitely another one of those things were you can't understand the old criticisms through a modern language lens, because the goto we have today has been tamed and brought to heel under structured program's constraints. However, unlike alephnan's objection that he doesn't see the point of the RPC criticisms which I think is the common case, the goto criticisms continue to live on as zombies long after the thing being criticized is actually dead and buried, injuring the more modern version.
Why are you conflating being informed or following one particular event with being obsessed with the news?
If Covid restrictions are so malleable in your city then you should find avenues that keep you updated, but once it's over you should also quit with the updates.
Knowing what happens in Ukraine every single minute is useless. If you see all those hints around you about a conflict you are unaware of, why can't you just ask around or at most read a recap article or two? Why would this event entail being glued to your screen 24/7? Just like with other people in this discussion it feels as though exceptional events somehow justify the constant consumption of the news.
We have the biggest independent European seed manufacturer as client and they shipped more this year than ever before and see no stagnation in orders even after the war started this is all anecdotal evidence and jumping to conclusion in the twitter thread.
IQ is quite heritible. This is especially so when upbringing is not neglectful. People who land very high paying tech roles are probably average higher in IQ than the general population.

Your daughter likely has the benefit of strong academic genetics. A child like that who puts in effort (i.e. works through a book) is going to do amazingly well. I'd also argue that families who value academics are also more likely to buy the books to do a couple hours per week in.
Do you have any suggestions for bitmap fonts?
I’m interested to see what happens if schools become truly race blind. I’ve heard that top schools may be >50% Asian. What would that mean for these schools? Would being predominantly Asian mean Harvard isn’t Harvard anymore? Would lopsided racial makeup make these schools less pretigious? Would they produce even more value with the top minds and nothing else?
App store taxes are good, actually
I played Dota for more than 10 years.

Besides the fact that I now have RSI (maybe not just due to Dota, possibly due to time spent in front of screen, overall), I realized after a while that I was a sort of people manager for 12-18 year olds and maybe I could just do the same thing at $DAYJOB and end up getting paid better :-)
Wind generators aren't free. Solar cells aren't free. And (even more importantly) backing storage for when the sun isn't shining and the wind isn't blowing is most definitely not free.
What's a better alternative in your view?
I have 2600 hours in Rocket League. It's a fair bit for a "casual" player, but it's got nothing on pros (who are mostly up over 15k hours these days). I have some friends I play fairly regularly with, but we don't usually play against each other we play with each other.

The main reason I still play is to continue improving, and I don't think I could ever do that effectively if I was limited to only playing against people in my local sphere. My rank typically puts me somewhere in the top 1% of players (and honestly, I'm not even that good. The skill ceiling is insanely high), online match making may be frustrating sometimes but it's the easiest way to find opponents who will push those boundaries.

Would a hosted server work well for people who are much lower ranks who are primarily playing to just mess around with friends? Probably. I would quit tomorrow if online matchmaking went away though.
If you imagine a curve of the light from a star, the dip in the curve from a planet passing in between us and the star is actually relatively small. They don't block that much light (and what they do block heats the planet, which in turn will radiate lower energy light)
It's weird that he's talking about this entirely in terms of fertilizer prices and not the fact that Ukraine and Russia are both export large amounts of food.
That “some famous mathematician” was David Hilbert. When he heard that one of his students had dropped out to study poetry, he said, “Good, he did not have enough imagination to become a mathematician.”
It's already on the Nest Hub Max, so they are already in the vicinity of end-goal.
I have a hard time believing this will be as severe as what we saw during Covid.

If you are expecting shortages, it should be in your interest to spend more now to capitalize on them. Especially if you expect inflation!

Unless a) you are worried about price controls in the future, b) you are a small-time farmer and averse or unable to take on debt.
Ukraine is the fifth largest producer of wheat and has reduced crop sizes due to the war. This is being offset by other producers like Egypt increasing production because there's a market incentive to do so. Will this result in a food shortage? Technically, yes. Will this result in some sort of noticeable food shortage? Probably not, unless people start talking about it and causes people to buy an unusually high amount of food resulting in a self-fulfilled prophecy. Will that be catastrophic? Almost certainly not, it'll be like Covid again when preppers buy all the pasta for a few weeks - an inconvenience.

What is the absolute worst advice to give? To tell people to go out and prepare. That will cause issues.
Glad you mentioned this. I went to a strong wealthy public high school with a high asian population (~50%?). When I was there, a lot of my friends were 2nd generation immigrants and their parents still spoke their native language at home. Their kids (my friends) were perfectly fluent/native in English but didn't do as well in the "edge vocabulary" parts of the SAT and I always figured that was why (in comparison to me and my english-at-home parents).
No, the US can simply create more USD and use it to pay off bond debt. Creation of USD doesn't incur more debt, but does expand the USD monetary base and inject more USD liquidity into global markets. The US doesn't actually need to borrow more to pay off old debt.

To restate: bonds and other loans are literally a policy tool to take in USD from or inject USD into circulation, in order to intentionally change the size of the money supply: "Open market operations (OMO) refers to a central bank buying or selling short-term Treasuries and other securities in the open market in order to influence the money supply." It's not like the central bank actually needs to borrow USD from the money supply; it's literally the issuer of USD and could create more at any time (or take it in and destroy it).

Why can the US do this? Because its bonds are denominated in its own currency, which world investors use. The demand for USD-denominated debt is a major benefit of the USD being the world's main reserve currency.
I remember an analogy question that required knowledge of alcoholic drink formulations. I was way under drinking age, and had no idea what went into a martini.
> and more troublingly some of the soundtrack behind payed DLC. How would it be if a movie charged you extra for listening to its score?

Why is it problematic that they include extra music in expansions? They're not leaving out an essential part of the game you bought, just adding more of it when you buy DLC. The base game soundtrack is so good that there are times I just pause the game and listen to the music.
I also pay more for pasture raised chicken eggs as well, but the regular eggs by me are almost always on sale for $1.50 for dozen if you're willing to jump between a few brands. That's a pretty massive difference, especially for someone with a family who probably goes through a couple dozen eggs per week.

I'm aware that making a software-engineer salary I can easily afford more humanely raised eggs, but I'd never judge my friends who are, say, schoolteachers, for not being able to justify eggs that are 6x more expensive.

inb4 the inevitable comment of "pasture raised doesn't mean anything, the chickens can still...." Yes I researched the specific farm my eggs come from to make sure it's humane.
Probably commercial baker's yeast.

Otherwise, pizza sour dough does not contain yeast other than what's naturally present in the flour. It's grown and multiplied during the process though.
ah yes, tried and tested C/C++ which has tons of memory-safety bugs leading to RCEs and more.
Good point. I interpret “nothing as worthless” to mean “extremely low worth, but not necessarily nil” and indeed instead of “worth” I could say “worth in aggregate”

Clearly there things worth knowing and not all of them were by Aristotle, Bach, Newton or Wittgenstein:-). The low pass filter screens put the froth; the selection of sources, the dross.

Not that I even read every article in The Economist, but I do read about things I wouldn’t notice or bother to were I reading from the firehose.

Side point: great thing about HN is that someone can say “here’s a clarification or contradiction in what you said” and have it often not be hairsplitting, so can spark a conversation rather than shut one down.
For fun, canonical religious texts call for, and celebrate, violence as well. This sits at the intersection of different concerns. How should those be handled?

> Nuclear will run out much, much faster, though, particularly when it comes to uranium we actually know how to extract economically.

With breeder reactors there is enough economically usable fuel to last billions-with-a-b of years.
Same thing for airlines. I hate the argument "consumers decided they wanted smaller seats, no free food or drinks, etc by buying the cheapest tickets." People just tried to get the best deal possible in the market, they aren't analyzing which airline has the best seats and amenities and making their decision from there.
I have personally encountered bugs on it. Not minor ones, but the page is giving a random php error.

This seems to undercut the "doing it ethically would significantly increase prices" argument for why it doesn't happen. Does this mean we could legislate the worst kinds of egg production out of existence and, once things settled down, only pay single-digit-percentages more for a dozen eggs, because most of the difference now is just middlemen gouging price-insensitive buyers? $5 more per dozen is a shock and would have people up in arms (probably literally), $0.20 more per dozen seems... not so bad.
Today’s creator economy was built on subscribers and patrons – what comes next?
The SAT, ACT, and even IQ tests, were originally created in part to help identity promising students who weren't from upscale backgrounds.

I'm not 100% sure that the tests can't be coached, but certainly not like the "leadership", etc.

And even if they can't be raised by coaching, the scores can certainly be lowered by poor education and a chaotic living situation.

EDIT: Most people who can pay for coaching are already sending their kids to the kind of high schools that serve to get them ready, so they are close to their peak already.

Even things like summer public service, there are consultants who can tell you, based on your target school, the best one for that school, like is it better to work on a clinic project in Honduras, or teach basic literacy in Burkina Faso.

Never mind that the plane fare to get your youth group to Burkina Faso would pay the school fees for an entire village, with enough left over to pay 1/2 the teacher's salary for a year.
This wasn’t my path, but many of my peers where I went to college had a similar type of story. They came from very poor areas like rural Texas or rural Georgia, and they got into engineering after getting into things like Lego sets and video games. They got great at math because it intrigued them even in their subpar schools. Aced the math SAT and then doors opened for them. I’d hate to see that door close.
