The course is "Linear Algebra with Applications" - and the OP explicitly wanted a course to learn linear algebra for non-math majors. It's not about "doing mathematics" in the sense of doing novel math, it's about learning basic linear algebra and being able to apply it to a non-math field.

IMHO for everyone who wants or needs to "learn actual mathematics" there are at least ten people who need "applied mathematics" in the sense of being able to apply well-known theorems from a well developed field (like linear algebra) and with zero need to ever prove anything novel, even trivial things; they need to understand the concepts and know how and where to look up the appropriate formulas to do the linear algebra calculations they need for their non-math domain. This OP wanted a course for the latter need and this course failed at this goal.

For a random example I heard recently; there's applications of differential equations in pharmacokinetics, so people studying pharmacokinetics need a sufficient math background for that. However, the appropriate math background for these students involves the general concept of differential equations and being able to understand a couple specific equations which characterize their physical domain, and do calculations involving them. For that use case there is no need for a skill in "doing math" - all the mathematical properties of those particular equations are known and they can and should look them up instead of learning how to derive them from first principles, much less making any new assertions.
At this point the lesson will be an expensive one for those still bag holding. It’s the retail investors who have their $5k holdings that will be most hurt. Not the guys running the exchanges. They figured out how to sell picks and shovels.
A Python library that treats filepaths as objects.

This was made redundant when the standard library introduced the same thing.

I’m still convinced mine is better, and offers a lot functionality the standard lib doesn’t.

It can be extended to add functionality based on file type (it abstracts the blob, not just the path).

It’s also a lot faster.

It also has limitations the standard lib doesn’t. For example, it doesn’t go to great lengths to support every file system under the sun.

So it’s going to lose eventually.

I’m not going to link to it because there are a ton of libraries doing the same thing. They might be even better.

But they’re all in maintenance-only mode.
> Given my situation, how would you try to convince me that I should learn math

Learning math has been the only time that I have ever been truly humbled by the aesthetic beauty of an idea. I didn't intend on studying math, I wanted to be an english major, but the woman I was dating at the time was somewhat of a math prodigy and I wanted to understand her world more // impress her. This may seem silly to some of the more mathematically mature people here, but the moment I fully understood Cantor's theorem it felt like my mind was dunked into this sublime understanding that left me in a daze for a week. Russell sums this up pretty well,

"""
Mathematics, rightly viewed, possesses not only truth, but supreme beauty—a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as poetry.
"""

> how would I teach myself the actually interesting parts without getting bogged down by doing lengthy calculations that a computer could do. The standard curriculum is so heavy on the latter and mostly absent of the former.

This wont be much of a problem if you're interested in pure math as numbers bigger than 10 are rare in that domain. I would recommend picking up an intro to proofs type book like [1]. The reviews are mixed but I would take that with a grain of salt as I suspect many of them were written by bitter students.

I believe agpl is one such license to identify competitors from using your open source code to compete with you.
Agree with your summary, but I am not impressed by the use of "stupid". Maybe "being willing to appear stupid", or "having beginner's mind" or "not making assumptions". But "stupid" is just click-bait. For that matter "laziness" too. Author says "work hard, but not all the time".

But the others (Arrogance, Carefreeness, Beauty, Rebellion, Humor) all seem right to me.

Yeah so our sense of up and down has everything to do with gravity but not vice versa.

Again, lessons to be learned…
Research and teaching are both important, and a smart university tries to use its professors' talents most effectively.

I studied at the VU, where Andy Tanenbaum, writer of a ton of famous CS books teaches. Of course I followed his classes. His books are excellent, but his classes are basically him reciting his books from memory. The jokes are literally identical.

At some point, more and more of his classes would be taught by Maarten van Steen instead; he's an excellent teacher who really knows how to engage the students and make them think about problems, instead of merely telling them the answer.

There was another professor who, as far as I know, didn't do any research at all; he just taught a ton of classes.

A professor who is great at one thing is not necessarily good at something else.

My biggest fear is a 1997 Albania situation but on a global scale. MLMs locked up 50% of their GDP, and it led to a civil war killing thousands. [1] It was all fun and games until war were declared. Then, well, war were declared.

When the schemes collapsed, there was uncontained rioting, the government fell, and the country descended into anarchy and a near civil war in which some 2,000 people were killed.

>you're not interested in it anyway, why bother?

I don't know enough to know why I should be interested.

>So you need to decide whether a vague conceptual overview is enough for you, or whether you want to really understand it.

That sounds like a much better way to start than by going back to calculating polynomial equations. How do I find materials geared for self consumption at a beginner level that teach concept and application first?
If you understand the basic English meaning of "maturity", the intended meaning of "mathematical maturity" should be perfectly clear.

Ask HN: Browser Extensions for Migrainers?
My wife is a migrainer and complains frequently about web pages with dynamic content. She is using an ad blocker (Adblock Plus on Safari) which does help with popups and advertising content but this often isn't enough. Any kind of motion on the page, while usually not enough to trigger a migraine, can be very distracting and frustrating for her.

Any suggestions on what she can try next? Willing to switch browsers if necessary. Thanks!
I would assume that class that is described as:

"4 hours a night 6 days of week and I got a C. Less the 25% made it to end. Don’t think many of remaining passed.

Got a lot out of it though."

Actually is abstract algebra and not highschool level. Nobody teaches remedial classes in such a way that only 25% make it to the end.
It doesn't always get a ton of notice when addiction is brought up but addiction to anabolics is an interesting phenomena in itself.

I started using anabolics years ago and slowly added more compounds over time. It eventually got to the point where I started to experience increasingly negative sides that I had trouble managing so would add further pharmaceuticals to the stack to mitigate the side effects of the anabolics.

What is interesting about anabolic use is that if abused for long enough or heavily enough (blast and cruise) going back to a state of non anabolics is actually difficult and can come with months/years of hormone / neurosteroid deficiency as you attempt to restart your HPTA. This is why most people are on replacement doses of testosterone for life after dabbling in this area which is interesting in terms of your typical reformed addict = quitting sense.
> “mathematical maturity” is something of a term of art in the field

Fascinating, it sounds like "MM" is tacit knowledge, which begs the question why it isn't explicitly taught.

In mathematics, mathematical maturity is an informal term often used to refer to the quality of having a general understanding and mastery of the way mathematicians operate and communicate. It pertains to a mixture of mathematical experience and insight that cannot be directly taught. Instead, it comes from repeated exposure to mathematical concepts. It is a gauge of mathematics students' erudition in mathematical structures and methods, and can overlap with other related concepts such as mathematical intuition and mathematical competence. The topic is occasionally also addressed in literature in its own right.

https://en.wikipedia.org/wiki/Mathematical_maturity
My university certainly didn't in most cases.
I used chroots, too, and it was useful but much harder to maintain than a container. Automation wasn't impossible, of course, but that was also complicated by concerns about bloating each chroot with copies of all of the system libraries & config files.

I used PHP in that era. It could be faster but then you're in the classic developer productivity tradeoff between, say, hand-coded SQL calls versus using an ORM, etc. The PHP frameworks which were comparable productivity-wise to Rails were also a lot closer to Rails performance-wise since they also had heavy abstractions, and they tended to have even more creative ways to create security holes. (I am feeling very old remembering arguing against enabling register_globals circa 1998)
For a book around this, I would recommend Scout Mindset by Julia Galef, which close to a self-help-type book but still highly informative while still being digestible. From the ACX review [1]:

> Of the fifty-odd biases discovered by Kahneman, Tversky, and their successors, forty-nine are cute quirks, and one is destroying civilization. This last one is confirmation bias - our tendency to interpret evidence as confirming our pre-existing beliefs instead of changing our minds.

I certainly agree with the premise that there is a deep epistemic flaw in the nature of our reasoning that we can counteract with conscious intervention, such as your suggestion.

My advice is to take the same course at a community college. In my locale the CCs are solely focused on teaching. The teachers are unionized, so it's a real career for them, and they're really dedicated.
I'm confused by your comment. You ask for one thing in one sentence, and then you say the complete opposite in the next.

This is absolutely, objectively, incorrect.

You might as well argue that you can build a self-sustaining base on Antarctica.

Of course you can't, because Antarctica can't support life. No amount of shouting into a bullhorn about adventure will change that.

It might be possible with an absolutely epic effort to airlift soil, nuclear reactors, nuclear and other fuels, machinery for every eventually (including chip fabs), raw materials that aren't locally available (which means almost all of them), and habitable structures.

At the end of that epic effort you'll have something that will barely have a toe-hold on long-term survivability. Possibly. If you're lucky.

Not only is Mars far colder, it also doesn't have air. Or surface water. So all the challenges are at least an order of magnitude harder.

And it's much much further away.

Rhetoric and wishful thinking are not going to give you a better life if you can't deal with the reality of the challenges.
I wasn't referring to just OCR stuff (or even just web stuff) though, my point was that there is enough information in the screen to make out detail - computer vision is more a broad subject than just scanning text. ~12 years ago i was working on getting a computer figure out where 2D boxes were in a feed from a camera (for augmented reality, not accessibility) and my algorithm was quite naive and primitive, but also the source was some awful web camera, not something "pristine" like a screen's content.

Of course i don't know that it is possible, it could be impossible, i'm just having the impression that there hasn't been much effort towards that approach. And TBH it kinda feels like it'd be much better to have a solution that works with "everything" without that "everything" knowing about it (or at least with very little participation from that).

Also FWIW i often use a "simple" web browser like Dillo or Elinks to read articles since it bypasses all the cruft and the usual suspect for making things unreadable isn't CSS but JavaScript.
map() is great in most languages but JS manages to WTF it:

> ['1', '2', '3'].map(parseInt)
[1, NaN, NaN]

> ['3', '2', '1'].map(parseInt)
[3, NaN, 1]

Somehow that doesn't seem like something a credible psychologist would say. And a skim through their other stories is in the same vein.
I felt this in Spain. In my little local university it seemed like they were gatekeepers. Some professors were hostile and treated you like if you were dumb.

It didn't help that I went to uni at 24 IIRC while I was working my ass off, so I wasn't that happy to put up with the BS.
This seems a little less severe than the floods. Whole factories were never fully recovered from those floods.

I think you're confusing two different things:

2) Wild ideas ABOUT a given work of literature
I wasn't referring to just OCR, check my other comment.
I'm building a method to use Twitter (via API) as a configuration management repository, storing encrypted configuration files in twitter, then using API calls from new network clients to grab the role-appropriate configuration files for a given service. So, "puppet, but with Twitter as the storage component".

It initially grew out of a test to build a shell-based encrypted method for posting and reading tweets, compounded by an underlying desire to figure out how to make twitter "useful" for me somehow. Discovering that stego data does not get stripped was an eye opener on the size of data chunks that could then be stored as tweets, which allowed me to push larger configuration files, while still having them be largely useless to random viewers.
The secret trick is proving theorems. Prove the Pythagoras theorem or prove that quick sort is indeed a NlogN algorithm (the latter needs some real math skills). A proof counts only when you can explain even the most boring detail in the proof. Books on math only tell what proofs and in what order you need to learn. I'd compare math proofs to functions, and understanding of math is a lot like understanding how complex functions work down to assembly level.

>"I will vote you out if you support this bill. End of story. "

I wish this threat would work on Senators who don't represent purple states. Come hell or high water, my home state will re-elect the same Democrats until the day they die or retire.

Edit: Yes, we can try to vote for a different Democrat in the primary but that rarely ever succeeds, especially against a tenured incumbent. I wish there was a runoff system so the vote isn't split amongst ~6 competitors and the incumbent.

You can get a tutor? TAs are pretty money hungry so almost any of them will do it for 25 an hour.

I had a Prof say "no matter how I clown around up here, you're going to have to teach yourself these things".

My perspective is that classes provide the motivation, then each student does what they do with it.

I don't think departments are financially incentivized to create happy customers, and I do still think this is a good thing after my own multi-year "sufferings."
> Yeah. I've been writing code as a job for a decade now and have never needed to factor a quadratic equation.

A lot of people never touch algebra again.

Some of us end up touching it a lot.

This is a bit of a tricky thing, in that:

- A whole lot of practitioners have very limited continuous math and deep CS needs, so some of these requirements are artificial barriers to some extent for many jobs.

- But is it reasonable to give them CS degrees without at least basic competence?

- Plus, part of the point of a university education is to round-out students and expose them to many things...
A tech company focused on logistics has at least one boss or founder who really likes factorio, the game for and by programmers who like logistics? Who could have guessed^^ It is cool if they let people expense it though, but motivating the 20$ per employee cost is pretty trivial. Compared to similar expenses like a yearly fruit basket, Id wager giving programmers/logistics workers a free factorio probably has a better impact on work performance. I think op is underestimating how much people learn from games, but it is also not exactly a high bar to pass, and Id wager factorio teaches more than most.

I am trying to solve for decentralization using file systems cross-OS as the primary design target. I chose the file system because it has a lot of complexity built in. If I can nail this I can decentralize anything.

I am passionate about this, because decentralization is the most liberating online experience. Share anything, in any way, to anybody of your choosing without third party restrictions, their privacy violations, and no weaponizing of your data/content for any purpose.

You are building a straw man from your misunderstanding of the OOP technique. As 'dragonwriter' tried to explain it to you that mathematical model of a square being a kind of a rectangle has nothing to do with OOP modeling. Liskov substitution principle tells you that a rectangle cannot be a super class of a square.
I'm honestly not sure (I haven't played with modems much), but I do know that doing a clean wipe of the eMMC or an SD card is way easier than a clean wipe of your modem. It's also a fair bit harder to check for anomalous activity, although with easier shell access, maybe that mitigates both problems?

To be clear, I think it's a lose/lose situation, because I want access to the modem in my pinephone, but I'd rather shell access require some kind of physical attestation (serial connection over the pogopins or something), instead of ... this.
hey man -

i don't think you really listened to the other guy.

i think he's saying that there's no need for break/continue with FP

because you simply approach the problem from a different angle

it's a different paradigm

that's probably why he asked for an example (not to belittle you)

i might do a filter before a map to recreate a lot of the functionality of a continue or break

and when I wrote/write OOP I might avoid break/continue because these things can be leaky
Maybe try different maths. I majored in math in college and even though I have a degree I would say I am pretty terrible at it. Some areas I understood almost immediately at least at the lower levels I took them such as algebra and combinatorics, but real analysis after like basic limits completely eludes me.
Someone who is tone deaf will never be proficient with a violin, or a theremin.

No amount of hard work would have allowed Stephen Hawking to succeed at sports.

Some pursuits are simply unavailable to those without the requisite immutable attributes. This is not politically comfortable, but it is true. I think the only legitimate question is whether mathematics is such a pursuit, and I'd like to be proved wrong on that point, but trying to convince me that anyone can do anything they put their mind to is wasted effort as it is so plainly contradicted by the available evidence.
Holy crap - I guess the days of just going online and making an account are over.
