Their contributor network thing exists primarily because of the value of the branding confusion.

Oh hey a lack of empathy, do you teach at Princeton perhaps?
I agree, but it's also worth noting sometimes the opposite can be true and it's more helpful for some people who don't want to smoke to drop the "ex-smoker" "quit" and similar language and start saying things like "I am not smoking at the moment" instead. It takes the pressure off and makes it seem like less of an all-or-nothing thing. And also means if you do mess up and have a cigarette, you've not failed, you've just had a cigarette and now you can go back to not smoking.

Not posting this to be contrarian, just on the off chance there's anyone reading this whose trying to quit and is looking for a new angle to try. If you can't quit, don't quit. Just don't smoke. This is what finally worked for me.

If we didn't do a stimulus we would probably have a huge recession and slow af recovery, just like 2009. That would be terrible for real wages.

If we did do something about inflation, what would it be? How would it it effect those poor whose real wage had been going up?

Ask HN: How do you work with holding companies?
We’ve had success as a startup working with privately held companies, but our encountering things we’ve never dealt with before working with new clients that are owned by a holding company.

A few example challenges:

* an exec said they “didn’t understand what we do” but won’t take their team’s word on approving a project their team really wants

* we’ve demonstrated that we could save the business a significant amount of money, but there isn’t a pre-approved budget for them to spend so they don’t seem able to find budget

* when we introduce new tools, even established ones like Google Sheets, the IT dept at the holding company is almost hostile about allowing it

As a team, we’re familiar with helping companies identify problems, create budget to solve it, getting IT’s buy-in and then deliver great results.

That doesn’t seem to be the way to win the support from holding companies.

Questions we have are:

how do we get into a productive conversation with the people at holding companies?

How do we help team members at our client feel safe when the holding company is involved (they often do everything they can to avoid interacting with them)?

Is there some other way to approach these kinds of clients we aren’t seeing?

Or is this a kind of client we should simply avoid?

Would love to hear your stories, challenges, and advice. We’re interested in learning all we can!
Wind doesn't pulse at exactly 1Hz for weeks, it also doesn't carry the same frequency over tens of kilometers. [0]

It's easy to handle anything for a while, like a crying child during a 30 minute bus ride. But when the same noise is extended over a 14 hour flight with no way to escape, you'll start to feel it.

Some people handle auditory interruptions better than others. Infrasound, to my knowledge, hasn't been really studied in a cross-field type of way. It's always just engineers doing measurements with meters and drawing graphs. There are very few studies on the psychological effects of man-made infrasound.

I don't know if she specifies it but, did she track it along the way? Also, it's just an airtag, why would it be sent to the constitution protection office directly and not to another department of the interior ministry (i.e EOD or any other place). Everything about this sounds weird tbh

And to wit: speculative fiction, fantasy, and horror periodicals are doing quite well. Asimov's, Analog, Clarkesworld, Lightspeed...

Perhaps worth noting is that these failing literary magazines are tied to colleges? Perhaps without readily available student volunteers the magazines can't afford to operate.
One thing that bothered me a lot in that book was the trio hiding out in the wilderness scrounging for food. They could do magic! How hard was it to sneak into a muggle supermarket and steal some food?! Or lie low at some pre-arranged safe houses? Could have had Dobby bring supplies.

I don't know how effective Taboo ambush tactics would be in the long run but not finishing off death eaters and letting them respawn was definitely a bad move tactically. Should have atleast dumped them all in a fidelius charmed warehouse or something in a Stunned state.

I'm not following. Yes, cryptocurrency mining and the buying of it with dollars has effects on the world, but "generate" dollars?? Economic activity doesn't generate dollars. Do you mean the standard metaphorical "make money" which really means "get paid"?

If a single dollar gets pushed around a small economy a thousand times in a day, it is facilitating economic activity, but that doesn't increase or decrease the money supply.
The Telegram bot is an amazing idea/feature! Especially because I noticed that a lot of how much I use these apps depends on how little friction there is to using them. I'd love to organise the random notes I take throughout the day better but always end up writing random google keep notes because it's just so fast and convenient.

God I hope they're not teaching one of them is correct and one of them is incorrect.
Lots of the very worst software was on odd mainframe OSes, like Univac's really alien operating system. It's dead, we'll never have the frustration of coaxing answers out of it.
For sure: Cloudflare is increasingly feeling like a better alternative to the 'bare cloud' providers, for most of my projects and I suspect also for the 99% of companies who are just building generic CRUD web/mobile app backends.

Customisability is AWS/GCP's strong suit, but as a corollary they don't make it nearly as easy to 'paint within the lines' - which is an odd UX stance to take when, by definition, 99% of your customers fall within the 99%. Personally I would have designed it to be 'simple by default, configurable if you need it', but far be it from me to say what's best.
I picked up this trick intuitively as a very young kid, perhaps 7-8

I break multiplication and division up into chunks of 1's, 5's, and 10's so that it's mostly just adding a zero to the end, or doing that and then cutting it in half.

I never learned multiplication tables, long division, lattice multiplication or anything else. just did this in my head.

So say you want to find 86 * 32

86 * 10 = 860

860 * 3 = (2400 + 180 = 2580)

2580 + (86 * 2) = 2752

It starts to break down for bigger numbers depending on how "uneven" they are but it's been pretty useful in general
I was responding to your straw man ("if you think that sometimes people can be influenced into having different genuine desires, then you must think this is true any time someone is manipulated, even in the case of spousal abuse") with another to demonstrate that there's a spectrum and more subtlety here than your initial response was acknowledging.

> especially when the manipulator has a conflict of interest

I think the conflict of interest argument is a good one for why advertising is generally dangerous.

> it's ethically dangerous to cloud that over with a philosophical fog.

Eh, fuck that noise. "Advertising is definitely bad so we shouldn't ever try to be clear about why exactly it's bad, since that might involve discussing some ways in which advertising is not bad, and we know it is bad."
For most maths, at least the stuff you'd learn before or during an undergrad degree the interesting maths is the journey. The teacher is attempting to teach you to ride a bike, and the student is like "this is stupid, I already walked to the end of the road".

The teaching of different ways of making the journey is (often) the destination.
I have struggled with this for the longest time. My field is nowhere close to Feynman's, but still, quite frequently I have found myself wondering "why", "why does this thing work this way?", "why is this, but not that?", leading invariably down a deep rabbit hole.

Sometimes it's not a complete waste of time, as I learnt about the innards of the systems I interact with. Most of the time it kind of is.
Right, but at the pace that many of these courses go, and with how the material continually builds throughout the semester, not getting answers until a week after the quiz, and hence two weeks after the lecture taught the material, is setting up a lot of people for failure.

By having access to multiple worked examples of problems, students at least have a fighting chance of learning how to solve problems _in parallel_ with the course material, rather than having to wait days or weeks to even know what they did wrong, while getting more and more lost.

Remember, these are Princeton students, some of the most brilliant and motivated minds of their generation, and the averages are _abysmal_. That indicates there's a greater systemic issue.
"mathematical maturity" would be a combination of "not smart enough" and "haven't studied enough". Highly talented people can reach high levels of maturity very quickly, people who are just a bit above average can reach a reasonable maturity through hard study, and below average talent means it is very unlikely that the person will be able to comprehend university level theoretical math.

A teacher who doesn't know you will not know if you're not smart enough or just didnt study hard enough, and probably doesn't care much, especially for an undergrad. For a phd student, they may care if they think they've identified a "diamond in the rough" that can be turned into a gem with some work, but that is quite a bit beyond basic linear algebra.
I have a reflexive aversion to reading anything from Forbes. I absolutely hated that "Forbes Welcome" page and it was so difficult to get around in the past.
The title "College algebra" in the US indicates material that is well pre-groups/rings/etc.; it is about the basic skills of computations involving manipulation of variables, often involving such topics as solving linear and quadratic equations, and perhaps inequalities.

At least at my university, the reason that such classes have a high failure rate is that the university is incentivized to have high enrollment numbers by admitting students who do not have the background to succeed at college mathematics at the level of calculus or above, and so need some pre-calculus courses; but someone who does not have a solid grounding in pre-calculus mathematics will often struggle to learn it when it is taught at a rapid pace at the college level—especially by professors most of whose teaching experience is with college-level math.
(It's the Princeton student newspaper, so the target audience pretty much knows that.)
Only a matter of time before we start seeing news of couples fixing their marriage by sharing AirTags with each other. I say this with sarcasm but recent years have made me wonder what is reality anymore.
Read the EO, it isn't secret, and doesn't seem to directly impinge on liberties, it is just the vague charter of what various agencies should be doing. I don't see any problem with the intent.

https://www.archives.gov/federal-register/codification/execu...

The problem is when you have a bureaucracy directed to "go collect intelligence" there is going to be a large grey area where there needs to be oversight, and there will always be people in a large org that need to be reigned in.

Anyway, the EO isn't the problem, it is the more boring challenge of oversight and managing large orgs.
"Binance today has announced that that it knows lobbying has to happen in public opinion as well as back-room deal making"
Finding alternative proofs is not a valid way to confirm the original proof; so... no?

You appear to be absolutely correct that no one has taught you what mathematics is. There's definitely a failing here in mathematics education; unfortunately this is not a surprise at all.

Validating the proof requires understanding what it is you're trying to prove, understanding what are valid proof techniques, and understanding the premises. You then check every step against this knowledge. It isn't easy, and tbh I usually couldn't be bothered after spending hours on a problem, but this is where results are obtained in proportion to effort.
My 2 cents: The author presumably goes to Princeton - the ivy league is in general a tough place to "start learning" things, especially STEM. Few of the staff would teach you the basics of anything, mostly because you are attending a research college, where teaching is the professors' side gig.

I went to an ivy league school, and a large portion of the people in the CS program did competitive programming/knew number theory and discrete math from high school etc. All the problems we got as homework were really intense - I'd consistently do more than 60-70 hours of studying outside of classes to keep up. Mind you, for me CS was/is like crack - I feel like I'd have put in even more time if I didn't need to sleep or want to hang out with my friends.

There are some intro classes, of course, but the quality of those varies a lot.

Edit: I don't mean to discourage people with this post. I was actually one of the few people who didn't have much of a CS/quanty background in my CS classes. My advisor told me to have a backup major in case I fail the tougher required classes, but I made it through.
Young Adult and Speculative Fiction are experiencing similar bubbles, I think. Not quite at the point that they're writing to their peers exclusively, but that does seem to increasingly be the case.
The article is from the Princeton university student newspaper, so I assume the author meant "Why won't anyone teach me math at Princeton?". It's specifically about the experience of liberal arts majors at Princeton, not some general thing.

You might have a point, and clearly are more experienced than I am about the inner workings of the german gov but, if they redirected what might be a dangerous letter, shouldn't they have sent it to another less bureaucratic institution instead of a random office where people would be affected for whatever dangerous stuff that's in there?
People like Bill Gates, Jeff Bezos, Warren Buffett, Satya Nadella, Sundar Pichai etc... are not physically intimidating at all. Even if you look at hedge fund managers, a lot of them aren't physically imposing at all. Even looking at world leaders like hitler, stalin, putin, Churchill all of them are short or average height. Modern power isn't about physicality, one person cannot take down even 2 people at once, rather modern notions of power is about control through the exertion of will.

Disclaimer: I do not understand enough of the code and of the domain.

The code itself looks slow and barely readable. A lot of for loops, few named functions. It needs a very strong refactoring to work properly with numpy. That should be done first, instead of pulling up the RuStIsFast card. It is not surprising that the results were not so great as expected.

In general, the article is too long to be properly understood...
> I didn't find any value

Not to be crude, but that seems like a personal deficiency, not a demerit of the article. The "commenters here" who "made better discussion than I found in the article," are discussing the implications of the article's information and presenting interesting perspectives. If you didn't find anything of value, perhaps you could try thinking a bit harder or for a bit longer. Others have done so successfully.

Re: #3, there isn't really a meaningful oracle problem now that there are reliable oracles.

You can make synthetic assets which track prices of e.g. stocks. There are a few different protocols in this space, such as https://synthetix.io/. The biggest hurdle, I think, is regulatory -- is it legal to make and trade derivatives of $synthIBM and trade it like derivatives of $IBM?

The author appears to have a framing problem. Her education is not somebody else's responsibility - it's hers. If she legitimately wants to learn, she already has access to the sum of human knowledge at her fingertips - for free in many cases.

It seems to me that her quarrel is rather with the structure and delivery of one particular course she chose to take. This may not be obvious to a lot of young people whose only life experience has been tied to the education system, but you don't need a formal course to learn a subject.
There's duckdb which seems very similar. I haven't actually used it for anything yet so YMMV.
In some universities (my experience is with European state funded universities) the effective goal might not even be to teach at all. Rather, the effective purpose is to function as a filter so that individuals with beneficial circumstances (whether it be talent, time, or being well prepared) can get good grades/credentials and others simply fail. Generally, there is little unstructured interaction between students and instructors.

One point in defence of this is, the skill/knowledge that is effectively trained is "how to learn", rather than specific courses and subjects.

For anyone not familiar, Roslyn is the language server for compilation, analysis and refactoring of code.

I don't understand the premise of your post but I would like to.

How does having these advanced features at the code compilation stage which is used by compiler and visual studio plugin programmers, have any affect on the complexity of application developers? The application developer doesn't have to think about Roslyn/language server at all, they just consume it's features. The application developer is concerned with the complexity/magic in the code, not how the code was compiled?

The need to rebrand is unfortunate. High framerate is not nearly as important as low standard deviation in the framerate. Naughty dog has blogged on the topic, but it was well known decades earlier in the demo scene. Getting smooth animations on old hardware was not trivial, but people discovered that the way the brain and eye work in conjunction, you could create marquees that looked flawlessly smooth at 8 fps provided you always redrew the pixels with very precise timing.

I’ve sort of known this for a while, but I got to see a demo a few years ago. A friend set up an old amiga demo on a modern fpga, and I saw him get all the timings right for it to finally look smooth as silk on the monitor he had. Then he attached the original signal to a second monitor and the difference was night and day side by side. One was smooth, the other jerky. Both the same fps.

> I continue to think Apple should have never released AirTags to the public, and should discontinue it. It's a very limited income stream, with limited use cases, and significantly increases the average person's risk of stalking.

You sure have a lot of strong opinions on what apple "should" do.

Don't like it? It's a free market. Don't buy it and if you're afraid of being stalked, check out the app they released.

I wonder how come all you people come out of the woodwork now that Apple released this thing, yet when Tile did there was no such forced concerned anywhere.
Slightly off topic, but when I noticed that there was sort of a market for prior exams for the CS courses I was teaching, I made it my policy to provide students with all prior exams. I'd have preferred that no-one had them (easier on me), but given how much an advantage having a prior exam is, I can't find it justifiable to favor those with the social connections that gave them access to such exams, over those who didn't-people with friends, people who belong to fraternities and sororities, etc. etc. etc.
