I'm afraid I don't know that info - I worked with the compiler toolchain and associated libraries so strictly speaking it probably wasn't even necessary to know the basics of signal processing. However it gets -complicated- interesting enough to be challenging, and whatever the next steps are this will at least put the necessary groundwork in place :-)
Here's my personal opinion about how you should approach this.

It's all well and good to want to cover undergraduate math courses. When you are actually enrolled in a university, you will have enough inertia and motivation to complete the courses.

However, when you are self-studying you are doing it all on your own. It's hard to be as thorough and cover everything.

And so I ask, what really is your goal here? You don't have to learn everything about mathematics, because that is in fact impossible.

My advice is to FIRST construct a bunch of projects, tasks or goals that require knowledge.

It could be something like
(a) implement a machine learning algorithm to do X from scratch
(b) implement a simple physics engine
(c) try to verify a number theory conjecture
(d) be able to solve all the exercises in a book
(e) be able to write up a compelling description/theorem/problem in math
(d) numerically solve the quantum mechanics equations of a certain system

Spend some time on material that will inspire you first to help get these goals. Numberphile on YouTube, or any of Brady Haran's videos, is a good place to start. But make the goals your own and make them personal.

Math is not a spectator's sport. Make sure to DO mathematics, not just LEARN mathematics.
That sounds like an awesome path dude, keep at it.

"Cuba does have a very low infant mortality rate, but pregnant women are treated with very authoritarian tactics to maintain these favorable statistics," said Tassie Katherine Hirschfeld, the chair of the department of anthropology at the University of Oklahoma who spent nine months living in Cuba to study the nation's health system. "They are pressured to undergo abortions that they may not want if prenatal screening detects fetal abnormalities. If pregnant women develop complications, they are placed in ‘Casas de Maternidad’ for monitoring, even if they would prefer to be at home. Individual doctors are pressured by their superiors to reach certain statistical targets. If there is a spike in infant mortality in a certain district, doctors may be fired. There is pressure to falsify statistics."

I wonder why the author does not include Cloud services in his analysis. Cloud is just getting started, has massive potential (business IT spending), can be delivered online (duh) and can be shown to be done effectively. Which is why you see lots of big tech co's investing massively there.

To borrow author's words, I believe for the next round, profitable tech companies will be Cloud providers (along with a Mall too), which will justify rich premiums.
The Congress of the New Urbanism is famous for advocating that our current built environment is not Goldilocks, and that the scales are tipped heavily towards sprawl and away from good urbanism. So it’s weird to see it publish the viewpoint it essentially formed to oppose (urban agglomerations are social problems to be solved by decentralizing and spreading out). It has a slightly different view of the nature of that social problem, but is overall aligned with the original postwar purveyors of sprawl.

More to the point, it doesn’t make any argument that the current level of growth is the Goldilocks zone. A YIMBY may read all this and agree that there’s such a thing as too much, while still thinking of the optimum as much higher than the status quo.

As russh says, part of this is that new mattresses are overpriced.

When I first investigated these things, I had asked them how, since they're only keeping the wood and wire, they can sell them at a discount. What they told me was that first, the beds they're refurbushing were originally donated to them, so cost them nothing. Also, since they employ people who are otherwise unemployable, they pay minimum wage, which keeps labor costs down. And thirdly, the government considers them a nonprofit work creation program and provides a certain amount of subsidy for the wages.

It's interesting to read a blog post that I guess caters to some audience that is "in the know" with whatever this guy is doing because all I got was the message "Being an influencer is not the answer" where I am still left with "..to what?"

I am pretty sure I agree with the sentiment that he is reaching for but I have no idea what he was trying to achieve with his profile. But if he did indeed spend over $100k building it up, I guess it's a good thing that he finally decided to stop if it wasn't working!

>> I'm much more likely to cut off my subscription due to a lack of satisfying content than distraction by other sources of entertainment.

I think their viewpoint is that "amount of satisfying content" is a metric that is purely relative to everything else out there. A complete global monopoly on all passive viewing content wouldn't help them if the entire world has moved on to Fortnite and video games in general for their entertainment.

> If he is smart he generates a different address for every single email.

1) I don't think it's one person, I've received multiple of these with different wording. At the least I think there are a bunch of copycats out there.

2) I received an initial batch of six to a few different mail addresses, and across about six different emails there was one bitcoin address used in four of them. I took a look on blockchain.info and a couple of payments of about the asked amount had gone through it in the previous few days.

What bugs me is that this is actual, criminal extortion on a large scale. Where are law enforcement?
I would also add that a paperwork heavy culture around discipline, can lead to all kinds of unwanted behaviors, especially when combined with exception creep. An example from the article was the reference that numerous events occurred that dictated contacting the CO, were the CIC did not. Administrative/Promotion fear is real and can effect behavior.

While I understand the need to honestly record and fit-rep staff. If leaders are not also teachers and if ALL failure has dire consequence, then how do people learn?

You end up with qualification programs and skill sets like there were on this ship. That culture created an environment where questions were taboo.

Plenty of money is being made by influencers, it may not last but it's not nothing. Maybe traditional business doesn't benefit as much, but if you're an attractive young lady, or an engaging funny gamer with a few collaborations it seems the sky is the limit. You won't build the next Apple, but it's a decent living if you can parlay your social media popularity into other businesses or revenue streams that generate money.
There's no [X] there to hide the section or even dismiss unwanted suggestions. That's the only place on the dashboard that is not mine, and which is only controlled by others/GitHub's algorithms, not by me.

> i have seen many people spill their guts on-line, and i did so myself until, at last, i began to see that i had commodified myself. commodification means that you turn something into a product which has a money-value. in the nineteenth century, commodities were made in factories, which karl marx called “the means of production.” capitalists were people who owned the means of production, and the commodities were made by workers who were mostly exploited. i created my interior thoughts as a means of production for the corporation that owned the board i was posting to, and that commodity was being sold to other commodity/consumer entities as entertainment. that means that i sold my soul like a tennis shoe and i derived no profit from the sale of my soul. people who post frequently on boards appear to know that they are factory equipment and tennis shoes, and sometimes trade sends and email about how their contributions are not appreciated by management.

Regardless of reliability it's important to mention that mortality rates isn't the be all end all of healthcare quality. Many people contrasting Cuban mortality and life expectancy statistics against the US have a political axd to grind, and they fail to mention key nuances. Chief among them, the fact that it's drastically easier to curb obesity when the government rations food.
This sounds really good. If one rather likes to stick with Apple's ecosystem, an exchangable or external battery could help much, too.
Suskind actually has a whole lecture on Youtube devoted to addressing the paradox of falling into a black hole from the perspective of the person falling in versus an outside observer. The outside observer sees the falling observer catastrophically turned into high-entropy soup smeared across the horizon, while the one falling feels nothing particularly special as they cross the event horizon.

I'm not sure Amazon really squashed Sears, any more than they squashed Toys R Us (which was operating with a gross profit despite their bankruptcy.)

In these cases, perhaps, in time, Amazon would have continued to eat away at their market share, but there's also the chance the they might have pivoted to offer a different unique value proposition that didn't require competing on price. The problem is that both fell prey to some of the perverse failure modes of capitalism, where those in charge of the company opted for self-dealing and short term gains, personal wealth, etc., instead of the viability of the company.

I think brick-and-mortar stores still have legs in this economy, though examples like Sears & Toys R Us amount to an own-goal, handing market share to online retailers on a silver platter.
"Yet people continue to argue how communism doesn't work."

Perhaps because there's a long parade of examples of it not working, and Cuba is not an unqualified success story -- not now nor for the decades it was propped up by the Soviet Union.

All this [these prenatal home visits] is possible because Cuba overflows with doctors — it has three times as many per capita as the United States — and pays them very little.

The country has an unusually high rate of late fetal deaths, and skeptics contend that when a baby is born in distress and dies after a few hours, this is sometimes categorized as a stillbirth to avoid recording an infant death.
>Try it with a dictionary, the words are distributed pretty uniformly, does the dictionary have no information?

That is not true at all: the dictionary is highly concentrated in correctly-spelled English words. If the dictionary was evenly spread over the space of sequences of letters A-Z it would not be useful at all, because next to Cat would be Cas and Cau.

Grocery pickup is absurdly useful. You ever had a hiking pack to whoever is bagging or try and fill it while doing self-checkout? It's not bad in all honesty but it's still more annoying than just picking it up curbside. Plus the side benefit on not whipping some kid in the face with bag straps because I turned around too fast.

As a former fund manager, I found his description of current capitalism quite close to my own. Particularly the bit where he says markets are good at a lot of stuff, but not everything.

Has anyone else had that sort of intellectual journey, where you discover libertarianism, you learn all the tropes, you feel very confident, and then after a while you pull back a bit after finding a few issues? And I suppose on the other side of the spectrum as well?
I'm definitely interested. I got into 3D printers and CNC machines at about the same time last year. I figured out the 3D printer right away and quickly went from printing out things on thingiverse to doing my own designs and outgrowing my printer and getting a fancier one.

While I've done about 250 print jobs in just under a year on my 3D printers after 8 months with the CNC I've cut two things. I got an entry level CNC (Millright M3) that runs the same GRBL on Arduino software stack and I've just been stumped after setting it up and cutting a couple rectangles out. The amount of time you have to put into setting up a CNC job is exponentially more and the amount of reference material out there is way less and way more specific to particular work flows / machines / pieces being cut.

I know people who have done exactly this. You’re looking for grad students - they often know exactly the right amount, and are very willing to work for some extra cash, and some (not all, but some) are happy to teach.

One way to find them is to contact your nearest research university’s department of math/physics/whatever and they can help match you with someone, or just post a flyer in their department office.
And there are tons of people in capitalist countries who disagree with what goes on there too.
In the US there's a patchwork of programs that vary according to the state and even the city you live in. The tragedy of the situation is that prenatal care is literally a case of spending pennies and recouping many, many dollars down the line in health costs for both the mother and the child. When you ponder the situation, it's truly a WTF moment.

You seem to be arguing with anecdotal figures from your childhood. I'm sorry the people you grew up with were hypocrites, but if you want to claim that reflects on either Computer People for Peace or the peace movement in general, you'll need to give us more details.
How countries count infant mortality is not the same. So it's very hard to compare numbers.
I feel the same every time I get into Twitter, it's like everyone is trying to sell me something, their brand, an idea conveyed in the most twitter like superficial way, it's just empty.

I curated it a great deal and ended up with various accounts that focus on various interests where I follow accounts that provide real data.... but almost all of it I would just go to their website to find anyway and I found that even with those accounts I was just filtering a great deal of stuff that I wouldn't read on their site too, but now I have to scroll past each item individually.

The end result was a larger time sink, and even emptier experience than most social media sites.

I think it might help some people like artists, writers, etc, but in the long run, I think it will just create inflation, and in the US it will create higher home prices.

Any time more money is injected into an area, it creates inflation. For example, when women started to enter the work force starting in the 70/80s, it lead to a dramatic rise in prices. Of course, I'm not saying that women entering the workforce is bad, I'm saying that when households effectively started doubling their income, it didn't result in more saved money, it resulted in higher house prices.

The same goes with the income tax deduction for mortgage interest. The idea is that more money would go back to the mortgage payer, however, all it did is factor into the calculus of buying homes, so people could funnel that "savings" into a higher mortgage payment.

If the US decided to give everyone $1000/month for free, I'm pretty sure that would just make the house prices higher by the equivalent amount.
One thing that worked for me was to have a community of fellow mathematicians to study with. There's a lot of cultural stuff that is kind of hard to osmose from books, such as for example, how to pronounce things that you read.

Mathematical notation is meant to be read out loud. It's shorthand for English, or whatever your natural language is. You should be comfortable seeing a sigma sign and thinking in your head, "the sum as ehn goes from one to infinity of eff of ecks squared times ..."

That's just the basic part of it. There's lots of cultural shorthands that are just kind of osmosed, seldom overtly acknowledged (for example, the precise meaning of "without loss of generality"). Maybe you can acquire them by watching videos, but if you can find people that you can hang out with that can teach you the cultural aspects of mathematics, that would help a lot. Picking up a book and reading and working through it and understanding it gets a lot easier once you have the culture down.
