It's worth pointing out that Mathematics is a "purist" scientific pursuit - it focuses on the theory for people for whom the theory is the point. The practical applications are for the engineers.

Arguably even computer science suffers from the same problem. Keeping your domain as an example, it will go one level higher - and teach you why this math is useful for i don't know rotating a 3d object in space - but not actually teach you any of the libraries (OpenGL, Direct3D, Unity, Unreal) to actually get it done.

In either case you come out with a degree with a lot of theoretical understanding, but you are useless to practical applications without further training.

This is by design, but it's debatable if it's a good design. Humanities does a better job of welcoming laypersons and giving them SOME basic awareness of history/politics/philosophy/psychology to survive in the world. Math and Computer Science do no such thing, and so we have people who have no idea how to do their taxes, or automate a basic repeatable process on their computer. Maybe we should fix this.

With how easy it is to lose an umbrella, and how difficult it is to retrieve most of the time, I prefer to think of umbrella as disposable items. Depending on where you live, your need for umbrellas might be different, but a significant amount of time, say ~20%, i need an umbrella and don't have one, so I end up buying some disposable version anyway.

I'm not sure why you're proudly displaying your repetitiveness.
You're missing the plot twist: The exact point she (I think deliberately) left out: The letter didn't end up at some "random office" - it ended up exactly where such letters would be expected to end up.

"Such a letter" meaning, a letter which had a "to" address of an allegedly existing sinister government org, contained a tracking device and looked like it was put together by a mentally unstable person.

Of course, whoever actually received this letter would get the impression that it was sent by a person or group worth looking into by employees of the BfV - the exact, correct organisation, based in Cologne, that watches these types of fringe groups.

Nothing surprising happened here. She probably knows it and that's why she is making an effort to have it appear like the place her letter ended up at was "random". But it wasn't random whatsoever. It was the logical place her and similar letters will end up.

My experience, also from an ivy league college, was that the beginner classes were taught well but often lacked rigor. But if you were looking for the level of rigor that introductory courses for dedicated majors would provide, you were going to have a bad time because those were often quite unforgiving.

For example, the 100 level math classes mostly did not touch proofs, just calculation. The 200 level math classes were almost exclusively proof based, but they didn't teach you how to write them. Either already knew how or you were going to have to teach yourself the mental framework on the fly. Contrast that with 100 vs. 200 level humanities courses in my college, where there really was a focus on teaching you how to argue points in writing.

How often do proofs come up in industry though?

Usually I find proofs are what you bring in the consultant for.

I'm not going to hand on heart vouch for anything like that as a generalist.

Combinatrics, Big O and set theory absolutely. Everyone is far better off with those.

In the end, it's all about sun-provided energy input. Coins or treasury, or freshly plundered lands really represent the means by which to convert energy into goods that can be consumed whether that's food.

But you can't get more slaves if you don't have more lands, but more lands means administration difficulty increases, which means you need more soldiers and bureaucrats, who are not directly producing food.

The ability to make methane on Mars is pretty huge, though. If you're mining the asteroid belt and need to refuel your ships, it's a lot easier to ferry fuel from Mars to the belt than haul it all the way from Earth. And methane/oxygen production is likely to be one of the first things we get going on Mars because we'll want our rockets to be able to make return trips back to Earth and we really don't want to haul the extra fuel and oxygen we need all that way.

Most of the economic incentives I suggest don't really start paying off until you have at least some decent infrastructure and a population of semi-permanent residents, though. It might not happen in our lifetimes, but you never know. Once the technology exists, it's just a matter of whether someone has deep enough pockets to make human settlement of Mars a reality. Once someone has a foothold, it gets easier for others to expand on that.

The world of literary journals is truly thriving -- there are endless literary journals available for free, online, and run by passionate teams of volunteers. Many of them, despite being free, are still able to pay contributors.

The demise of some university funded literary journals is a different issue; costly staffing, print, and management costs are not necessary, and remnants of a different era. Yes, they can provide a lot of value, meaning, and career payoff, but they are not as necessary as they used to be, as the proliferation of online journals has only accelerated.

Of note, Ycombinator funded company Submittable used literary journals to fuel their successful start, by providing a service for literary journals to manage submissions. I really hate the role of money that Submittable has injected into the literary journal world, though. They've made the practice of "submission fees" incredibly easy to implement, and encouraged literary journals to charge submission fees to writers. A practice that, unfortunately, has proliferated under their influence.
That's not an accurate reflection of HN. It would be more accurate to say that the topic is divisive and so has blocks of strongly-feeling users on all sides of the topic. That's true of every divisive topic and it would be unreasonable to expect otherwise.

Radar Interference Tracker: Open-Source Tool to Find Active Military Radar
This is a great question, and it gets to the heart of practical privacy online.

DeGoogled Chromium does actually have less telemetry problems than Firefox, so it's really easy for DeGoogled Chromium proponents to say that it's the most private. The issue is that DeGoogled Chromium is Chromium, and Chromium is a less privacy-capable browser engine than Firefox.

That could be a longer conversation, but the short versions:

- Chromium lacks a number of privacy features that Firefox has, including some anti-fingerprinting options that can be enabled through `about:config`, and container support, which is a really big deal for isolating site data and avoiding correlating user sessions on websites like Github/Youtube/etc... with incidental visits to those sites.

- Chromium's extension API is hobbled, particularly in a couple of areas that Ublock Origin cares about. The wiki goes into more detail on this[0].

----

The mistake is in looking at the small amount of (admittedly bad) data-leakage that Firefox does have and being so worried about that information being sent to Google/Cloudflare that you pick a browser that is less good at keeping you private on every other site you visit, including visits to Google/Cloudflare pages.

Thinking practically about this stuff is just a really hard thing to learn to do, at least it is for me. Maybe other people are magically good at it. But I regularly find that it's helpful for me to sit down and think through my privacy goals more tangibly in the form of "how much data is X actually leaking, what should my priorities be based on the volume/nature?" A lot of people worry about privacy problems in the wrong order.

DeGoogled Chromium does have better defaults than Firefox in multiple areas. It's just that the privacy benefits from those changes don't outweigh a crippled Ublock Origin install.

One thing people don't really have an intuition for is just how chaotic the ancient world generally was. Banditry was basically normal, murder was a 'personal matter', civic infrastructure investment was generally not a thing, etc.

Empires like the Romans made some basic inroads into these problems (although in Rome, murder was still a personal matter, banditry was still the norm, etc). Building an aqueduct or a road is a massive quality-of-life achievement for everybody.
I don't follow why you think anything about this is weird. I tried to explain that what happened here was what anyone with a little knowledge about Germany and its government agency would expect to happen. She either feigns ignorance in order to make this look like huge story, or she's really so ignorant as to not know that not all government agencies in Germany are seated in Berlin. She should have done more research.

> The way you frame it is only a problem if civil servants are not part of society and that people don't have an influence about what the government spends money on, that is: you don't live in some form a representative democracy.

I mean, we don't live in a representative democracy. Not in the sense you're describing.

(Assuming you, like me, live in the U.S.) Civil servants are not elected, are not directly accountable to elected officials, and are certainly not drawn from a representative cross section of the public. You may feel like they represent you, but that is (to be frank) little more than an expression of your own place in society. Civil servants form a discrete and powerful class, with their own interests, unions, and lobbying groups. Ignoring this is, optimistically, naive.

After years of trying to be productive with to-do apps, I've found that nothing beats the flexibility of plain old pen and paper. Even analog systems like Analog or Bullet Journal impose rules of varying inflexibility, and that made them very unappealing, for me at least.

I guess this is because people have different ways of thinking about goals, tasks and timeframes. For me what works best is a 'week todo' that contains coarser/larger tasks and a daily todo that contains more granular tasks, often sub-tasks of the weekly ones. Adopting this method has made me more productive than I've been in years.
Math is math, not programming.

No it's not about react or ror.

It's about solving actual real life problems. 99% people don't do CS to do academical research, but to work on life change products(and that's more likely to come from user research and fast prototyping, than from theoretically perfect fundamental research).

Some people build millions dollars software products, solving real life problems, without having a clue what big-O, quadratic functions, or even a lot of actual theoretical programming concepts are. And I personally know a bunch of those people. Some people know almost everything there is know about CS theory and never build anything useful to anyone.

Physics have literally nothing to do with CS or SWE.
I think this is just pointless elitism.
My wife and I had our first child last October, and we wanted to collect the cord blood to donate, but the hospital said they didn't do cord blood collection. I know you can't speak for our specific hospital, but would that be a problem for other customers? Hospitals preventing nurses from collecting blood because of safety or liability concerns?
"The way the course was run did not at all set up students to succeed — or even learn math. For example, though we were provided with practice problems to prepare for our exams, we were never given solutions. My class consistently begged my professor for these, yet all he could say was that not providing them was departmental policy, and it was out of his control."

The calculus courses when I was in college (not at Princeton, in 1986-1990) were taught by assigned reading and problem sets in the text book, which were graded by TAs, and a run through the proof that a given technique worked in the lectures.

It is what it is.

I’m wondering why the title got changed myself. Based on the comment at the top I have to assume YC, and therefore this entire board, has an investment in selling it (web3) to others. So, they changed the title and defined how it should be discussed before nerfing it off the front page.

I don’t think that there have been “flame wars” here about it either, nor do I think it lowers the quality of the content here. The idea of NFTs holding value is debatable and naturally polarizing because of how humans form trust channels.

Some are OK in believing a brand new corporation, with little or no oversight, will always do the right thing when it comes to maintaining their records of things tokenized (such as providing legal guidance to courts in proving ownership status according to the software they wrote to color the object with a coin). Some don’t think that’s a thing, now or ever. When there is repeating behaviors from the discourse that tells us something about the divisiveness of the subject itself. When there are repeating behaviors from management about a particular topic, that’s something else entirely.
Me too, but some banks/payment services don't allow that – ostensibly for security reasons...

Even when I did get a "real phone number" (that concept irritates me to no end), one of these first required me to send a phone bill as a "proof of me owning that number" before they would let me set it for 2FA.

I guess that's just what happens when blending/confusing the three distinct concerns of spam/fraud protection, 2FA, and user identification (for inbound P2P payments) into a single identifier.
Maybe - it depends on how much that bit is weighted.

>Like if you were pushing out liberal arts majors without any grammar courses.

I would expect very few liberal arts majors (who aren't majoring in linguistics) would take a grammar course.

Linear algebra is actually sort of interesting. Before computers were commonplace I'm not sure how widely taught linear algebra was. I certainly never took it but was admittedly not a CS/EE major. I do remember a robotics course I took in grad school that involved doing these ugly matrix operations by hand. (No Matlab.)
