Spivak’s Calculus is hands down an excellent book for a first course in real analysis, and I’ll die on that hill(it’s only real competition is Analysis 1 by Tao, in my opinion).

Anyone that says “it’s just a calculus book; it’s not good for introductory real analysis” is invited to go solve every problem in, for example, the chapter which defines integration, and compare the difficulty with problems in “traditional” analysis books.
I’d have more sympathy if this were someone from the inner city or rural America. But they’re in Princeton crying about not getting answers to problem sets. As if the first time they’re not spoon fed something, it’s time to trash the department. If you can afford Princeton, buy a linear algebra book with solutions. It’s as if a Math major said, “Oh I would love to read Hemingway but there is nobody in the English department to tell me what questions are on the test. How can a Math major learn to read? Where in the world might I find a clue about Hemingway?”

Yes - math education can be awful, but this snowflake needs to lose the entitlement.
She wasn't talking about solutions to the exams. Sounds like they didn't give solutions to the practice problems.
This looks like a situation where Numba would be very useful.

I've made it a hobby of reading beginner Calculus texts. I believe it to be a fascinating thing to explain and teach. Recently, the Teach Yourself series re-released their 1992, Calculus: A Complete Introduction. It isn't clever like Things Better Explained, with the visualizations, but does share excellent examples you already understand as unusual and then provides a pathway to using the integral. Like most good Calc books, just bring algebra!
They really need to dismantle their old turbines, that's for sure.

Re-powering can probably give much more power output but with a fraction of the current number of turbines. I'm not sure how large and modern turbines fare against older and smaller ones, I sadly get a feeling that they're not much better or maybe even worse. I think blade tip speed needs to be high for high efficiency and that sounds like it can be noisy.
I disagree. word definitions are not handed to us by god; we get to choose useful ones. to me, the "negative consequences" bit is what makes "addiction" more specific than "habit", which can be of bad, neutral, or even good quality.

maybe exercise would have been a better example. there are people who damage themselves through compulsive overtraining, but there is often a compulsive element to moderate exercise. a person with a solid 5x1hr/week regimen will often feel bad if they miss a day and be very reluctant to do so. but this is not a bad thing at all; it is a very healthy habit.

For me, a well-established habit can be different than addiction, but they're definitely related. What I look for is a) whether I'm using X to avoid discomfort, and b) whether using X helps create or sustain that discomfort.

As an example, I play casual computer games to take breaks. So popping open my current favorite can be a habit. But I've had friends addicted to WoW, such that they were spending enough time in it that it was making their lives worse. The more they played, the worse their personal problems got, causing them to seek more relief through WoW.
Have you experienced this personally? I ask because this hasn't been my experience as a parent of a K-12 student. They are expected to show and be able to explain their work, and the teachers use that work to gauge the student's understanding of the material.
I wouldn’t attribute this to progress. iOS and macOS have always heavily prioritized accessibility. For Google, you can see in this example and in the flutter example that accessibility is an after thought.

>why isn't there more talk of curtailing what the President is allowed to do unilaterally?

Because the Presidents job is to distract from - and take the heat for - the crimes of the nation.

The nation has crimes it is keeping secret. These are national secrets, the revealing of which would harm the security of the nation.

Whether you think these national secrets being revealed would be a catastrophe, or indeed a badly needed justice for the inhumanities being committed in your name - it is the Presidents job to make sure the nation stays safe during the discussion.

Which is why CIA powers are not discussed until the weight of public opinion itself, threatens the 'security' of the secret-keepers/nation.
People are downvoting this because something like 2-4 weeks ago The Science said this was disinformation. It takes time for the reverse in course to propagate.
I was puzzled at why IBM would be designing fonts of all things. Then I remembered they started out as a typewriter company and it somehow all just made sense.
No, only some of those. The CIA is well known for having burned/destroyed documents so they couldn't be declassified, so no one will ever tell.
If they know how to do (rigorous) proofs, then Spivak would be good. Otherwise it would be far too advanced. It's essentially an introduction to analysis.
So the author took one class that was unnecessarily difficult. That’s unfortunate and worth following up with the Math department on. But expanding that into a full-length article with the thesis of “Why won’t anyone teach me math?” seems like a stretch.
100% agree. I can't stand pages like this. It adds nothing but jankiness and confusion.
There are multiple entry points, depending on your goals.

However, if your goal is to learn mathematics for the sake of art, I recommend Kolmogorov's Elements of the Theory of Functions and Functional Analysis.
Atlassian's problem isn't a lack of essential features, it's the flood of completely non-essential features that make it impossible to configure correctly without years of experience. It's essentially the opposite of the Unix philosophy of doing one thing well, each Atlassian app tries to do 150,000 things and does 149,998 of them extremely poorly.
I've been terrible at math in hs and then I started doing programming and realized that math ain't hard and actually liked doing it

I managed to improve and then I had math at higher edu institution

and oh boi, I instantly had no interest in doing it 4fun, just learn, pass and move on.

idk, I feel like there's too much stuff to be done (a lot of courses + you gotta learn other stuff like "real world" computer's related stuff) and there's lack of time for 4lulz messing with fancy topics like maths, but on the other hand I've been working + studying, so maybe that's why
I think there are shades of correctness to your answer (at the upper echelons of math study, as it were, there will be no answer book for you to check), but the act of confirming your answers should be transitioned in and taught; which from this author's perspective hasn't happened. Further, there should be education, refinement, and strengthening of learning to validate one's own answers before leaving them to flounder in a 200 level STEM-focused course.

(Honestly, I'd probably have a better relationship with math if it were taught to me in the method you seem to require as "actual math".)
That's a lot of scrolling to github link..
> Attempting to learn mathematics as some sort of pattern matching, which is where having large sets of questions and answers to study is useful, does not work

This is actually a really good point, but unfortunately this is actually how public education through high school tried to teach math. I remember the agony I experienced as a 3rd grader for not being able to memorize "multiplication tables". Instead I took the approach of trying to understand what the mathematical meaning of multiplication is. This was to my extreme academic & mental detriment as we were not graded on understanding, but instead graded on how fast we could answer math questions.

I felt like a total failure. It's much faster to memorize vast multiplication tables and recall them from memory than trying to understand first principles.

Obviously, my concern over this was totally pointless as I've never been in a career environment where I was told "just memorize the answer, don't bother trying to understand anything".
This is useful. As tailwind team is very active, I won't be surprised if they decide to embed an official tool like this one.

It's highly likely that there is a large pool of exam questions, and every year, they are split into "practice" and "actual test". Providing a gold standard answer would lead to memorizing solutions in a way that providing all the questions does not.

It's likely the point is to talk to the professor about the ones you're having trouble with, or where your study group disagrees.
There isn't any supporting material in the article (the links to course review comments are behind an authentication wall) so it's hard to be sure, but it sounds like the answer is "because you had abusive teachers". By that I mean psychologically abusive people who derive pleasure from seeing students struggle in pain. It makes them feel better about themselves.
What exactly is being rationalized? I've had opportunities and I've chosen not to take them because I didn't think they were aligned with my moral structure.
If you want an addiction that no one ever talks about, addiction to money would be a big one. That's seen more or less as a virtue in our society though.
I’m not sure how to answer that. I fail to see how it could bother someone.

With these kinds of protests you always have to worry about infiltrators --like the Greek austerity protests where confederates committed violence while dressed as protesters to make the movement look violent for the news audience.
It's very simple to disagree. The CIA just goes out and burns classified documents it's not okay with being eventually declassified, for example https://www.nytimes.com/1997/05/29/us/cia-destroyed-files-on...
There's an argument to be made that some of the current largest market cap companies in the world are analogous to royal families, in terms of centralization of capital vs freedom of decision making.

My mother was a professor of one of my college STEM subjects, and had used my textbook in my introductory class. My teacher was horrible, and she agreed. So she gave me her teachers answer guide, which not only provided answers to chapter questions but explanations (some including comments about where students might go astray, and why, and why that was wrong).

I gave up on lecture, and taught myself the subject by doing problems out of the back of our chapters. Aced the class, changed my prof next semester, changed my major to the subject the semester after that, and graduated with honors.

To this day, I am dumbfounded by an approach to STEM education that would withhold a critical tool to iteratively learn via problem solving.

It would be like XP without writing tests. You ship your knowledge to the exam, and pray it doesn't break. Seems ridiculous.

The time saved on the commute was an excellent deal, for me it was about 2 hours saved per day where I could work and get paid and as soon as I clocked out I'd be instantly on my own time. But since I couldn't afford a separate room like a home office, using my bedroom for work made it feel like I was always on call and it added some psychological toll. I also noticed that during the cold months I'd have fewer days of stepping out of the house as well as less physical activity. That that made me feel a bit lethargic but I understand it is my own fault for not planning better a schedule to include enough workouts. Now that I am back in the office I miss working from home quite a bit. I am planning to WFH in the future but better prepare for it in advance.

> It made me realize that myself, along with many students, mask their points with language because they have nothing to say, or are afraid to say it clearly

You're right about high schoolers using needlessly complicated writing, but this isn't why. A high schooler would use needlessly complicated writing even if he was eager to share his ideas about a topic.

The reason is that K-12 schools teach this style of writing as an aesthetic. Other parts of the aesthetic include scattering your stories with "symbols," so that they mean something other than they appear to, and exaggerating your and your characters' emotions.

A student who grows up immersed in this aesthetic would not secretly prefer a more simplistic writing style, any more than a person who grows up eating American food would secretly prefer Indian food.

Your friend was inducting you into the aesthetic of modern journalists and bloggers, but if he was instead reading the academic humanities, or if he was a time traveller from the 1950s, he would have been perfectly happy with "utilize."

Of course, plain language is better at conveying information, so I'm fully on that train myself--now that I've spent some time out of high school. But it's normal to adopt the aesthetics of your surroundings, and it's not a sign of masking anything or being afraid.
I don't know if it's true of all schools, but I had a very similar experience at another Ivy League school. Took the first semester of linear algebra, got a very respectable grade, but really didn't learn much because the class wasn't structured to do that. It was there to make STEM majors prove they were good enough. I wasn't a STEM major, so didn't need to keep going with that kind of hazing.
Professional triathlete Lucy Charles-Barclay had Covid in November 2020 and then won the Ironman 70.3 world championship 10 months later. Everyone is different.
This. It's farcical to believe that the hard part of getting around tens (hundreds?) of millions spent on lobbying for regulations, plus managing the constantly evolving tax code and all the legal and financial liability surrounding that, is writing the actual code. That's the easiest part by a factor of 20.

FOSS tax prep software exists, most of it is ok, some of it is pretty good, but it's really a legal and regulatory problem that is not going to be solved by developers.
Sadly, in my experience, these was the case in introductory STEM courses. They could care less whether you understood or not. There were plenty of people in line behind you, so your personal experience didn't matter.
This is a big reason why I encourage people to take as much STEM as possible at community college instead of public university. Faculty are focused on teaching, not research and publishing. You have a better chance of actually learning something.
My partner and I make music. It’s a nice low-stakes unwind from software jobs but also kind of feels like it uses a lot of similar muscles in a nice way. Since Covid we’ve gotten back into recording and have started doing electronic stuff (previously all guitar based).

Yep, the cheap dedicated servers I have are with Kimsufi and SoYouStart (both OVH brands), though the lines are limited to 100mbit and 250mbit respectively and IIRC neither is guaranteed (something like X servers sharing a gbit+ connection, where Xrate > TotalLineRate) so I can usually* but not always get 100mbit out of kimsufi. I've not really pushed the SYS machine's resources yet, it is a recent addition to my dominion.

A search engine pulling data from /dev/urandom as in the post that started this discussion is likely to impact other uses of the 100mbit link from Kimsufi. Worse if bad luck means multiple hits of that sort at the same time.

I have rules for this after about a billion years of experiencing it.

1. minimize dependencies - batteries included is best unless it will take forever to write, keeping a local copy (like Linus' idea of static linking) is next best
-- a certain amount of reinventing the wheel is tolerable if you are optimizing for mimimal rot.

1a. ORMs and testing packages rot because what is popular today becomes unsupported when the next flavor of the month comes along. Ask yourself whether select Customer, ID from Invoices really needs that layer of abstraction. Ask yourself if that test is really so complex it needs a framework.

2. Mocks sounds great until you have a rush feature or incident to manage, and get busy. Use integration tests for things that would need mocking. Insist on green across the board or it doesn't ship as a cultural value.

2. use neutral (https REST) APIs to segregate logical components. The analogue of this in single-binary programs are pimpl idiom type things, depending on the language. This acts as a firebreak so you can replace code behind an API without the consumers caring.

3. version all apis and all data. Further provides firebreaks and lets you manage users by degrading QOS for older versions till they upgrade.
I think part of the problem is that it became a bubble. Literary authors weren’t primarily writing for the general audience, but rather their specialized peers.

As this bubble became more separated from the mainstream, interest in these literary magazines shriveled.

> I've always said that there's no such thing as an ex-smoker; they're smokers who haven't smoked in a long time.

This kind of absolutism may end up discouraging present-day smokers from trying to quit at all. It's also not necessarily true. Some people do go from being smokers to hating the sight/smell/thought of smoking.

I'd like to augment request one step further: Is there anything that kinda goes through the fundamentals all over again, but is programming aware?

I have studied this and as yet I am unable to find any evidence that Truman thought Japans surrender was imminent. All evidence I have found seems to point to Truman actually believing that dropping the bomb would save lives- both American and Japanese.

> The approach of creating an accessibility tree can take extra work from developers instead of it just working.

Because this isn’t true unless you’re using a nonnative framework like Flutter. If you write your apps in HTML or native frameworks, the tree is built automatically. You only have to fiddle with it if you’re doing really custom stuff (which almost no one is).
The point is, instead of giving investors risk free returns, inflation is effectively a tax on the people and entities hoarding wealth with no productive purpose, and it benefits debtors.

We’ve had a carnival ride of cheap debt forever, which has powered and established many really dumb businesses. IMO, we’d benefit from a few years of 5-10% inflation.
