That’s a fair point. But still, the relationship between the root, 5th, and major third are very much connected to the fact that they are specific multiples of that root frequency, and are the loudest overtones typically audible when the note is played. The root is not totally different from chords built on it.

I meant to add more to my top comment. I think the author does fairly well at their mission despite potential nit picks like that. It is really cool to see somebody learning and being excited about putting all the pieces together. The beautiful thing about music is you can go deeper and deeper as much as you want, and there are various competing ideas about what it is and how to talk about. Programming has a similar kind of depth to it.

This ^. If you wonder, 'what complex numbers are all about', then chances are you can't give the universal property of the tensor product, or the definition of a Riemannian manifold, or a complex Lie group, either.

I suggest to look at the literature listings of any undergrad math curriculum to get suggestions on what to start with. There are reasons 'linear algebra' is usually taught before 'Applications of the representation theory of Lie groups in special relativity'.

Or maybe I'm too conservative in my view on math education?

I've had teachers separate languages (or styles, or paradigm) in 3 categories:

* Imperative languages describe how to perform the solution.

* Functional languages describe the solution.

* Logic languages describe the problem.

I'm not sure I actually agree with this categorisation, though.

Wishful thinking. The main issue with Model 3 is just that they can't make batteries fast enough. This is a solvable issue, and it would normally be considered a "good problem to have" (not being able to make products fast enough to meet demand).

The only reason this is seen so negatively right now is mainly because Musk has set such high standards for Tesla by trying to increase production by 5x within 12-18 months and hoping everything will go perfectly smooth.

I think there would be a general decline in life quality but with ups and downs so you'll never know if tomorrow will be better than today so there may be no clear point when you're sure you don't want anymore.

Once you've lost too much of your mind to really know what's going on, you're not someone who should be trusted to make that decision- just as we don't think mentally ill people should be trusted with that decision.

An AI Resident at work: Suhani Vora and her work on genomics
Maybe it works like that in Singapore. Personally, I think it's a pity. Ancient Greece was far from an utopia - even "enlighted" Athens used slave labor in nearby silver mines and regularly voted to declare wars on other peoples. But some solutions were thought-provoking.

By moving public matters to a website you move them out of sight. Out of sight, out of mind. People think less of common good, and how the city should work. Public matters become distant, abstract and impersonal.

Many people value restaurant not exclusively for the food - which can be a bit stale or cold if it's delivered to you - but also for the service, pleasant atmosphere and sometimes to meet interesting people. And to show off.

I don't know how it works in Singapore, but in a traditional shop you can examine goods you'd like to purchase, try them on, ask questions, or even negotiate a little bit. In my country it's rare that a shop's website has accurate and complete descriptions for all items, or even photos from all sides. A shop may have a contact form or a person answering questions through instant messages, but you can't know if he/she is active and not on a coffee break.
To make a perfect shop website you have to make special cases to emulate many kinds of service that you take for granted entering a physical shop.

Delivery works well for easily defined items like books that don't have many variants, such as books, and even then if you know precisely which book do you want. A recommendation system might or might not give you valuable suggestions. In a shop or library, you can browse a book or ask the librarian or clerk.

In some ways, delivery shops and shops in general are very inefficient. For example if you buy physical books, everyone must have their own book, whereas in a library one copy can be used by many people. In some ways it's much more efficient. Digital books are even more efficient, but publishers fight very hard to create artificial scarcity and disallow copying, which is next to free in cost.

But a digital version of a soldering iron, a hammer or climbing equipment won't suffice, and this could be handled similar to a library, even for a fee. These items are only needed occasionally in most homes - if you run your own workshop, it's another story.
Yeah this is absurdly and disgustingly bad. It would be like dividing all the money a company expenses for an employee (laptop, lunch, outings, trips) as "earned income".

Under this bill, someone who makes 30k stipend per year (and 41k tuition waiver) would go from paying 2k in federal taxes to 10k.

That means, before state taxes, they would go from living off of $2333 per month to $1666 per month, a difference of nearly $700.

For someone who is already barely breaking even as it is, this is enough to send them into debt for sure, and at $9.80 per hour is worse than most fast food jobs
You are testifying that it is great to live in an isolated cell, without any means of honest person-to-person communication.

If you'd prefer to communicate exclusively through Bill's system, you go for it. Just be very aware that you are surrendering anything you might have fought for. You become the most expensive and irrational gear in Bill's machine.

I'd much prefer if smart cities were smart about community, about coming together, about meeting likeminded people in fun social settings (such as cafe's).

There is a fundamental invalidity to digital communication. It lacks most the interaction, simply doesn't have the bandwidth. We're humans emulating intelligence, not intelligence itself. The difference can be subtle, and I suspect most smart city designers will have trouble wrapping their ratio's around what it means.

It is beautiful that if a lot of people are upset, the city seems upset. These smart cities will seem perfectly calm concrete. Your best move is to stay perfectly calm. Proceed into your autotransport. Proceed into your ideally suited job.

>The basic principle of decentralised search is an individual only needs a tiny fraction of all knowledge available,

That may be a reasonable assumption but it omits a major tradeoff: some types of "knowledge" require the search engine to "see" the entire index and synthesizing such knowledge cannot be delegated to decentralized nodes.

To reduce the search engine tradeoff to a simple math analogy: You can "decentralize" the calculation of a SUM to individual nodes. However, you can't decentralize the calculation of an AVERAGE. Divide-and-conquer strategy of calculating an average will give the wrong result.[1]

Some searches are like "SUMS", and some are like "AVERAGES". If a search is pure text retrieval without regards to relative weighting or ranking, decentralized nodes with each holding partial segment of the index will work. (E.g. you want to retrieve a chili recipe so your search query hits the decentralized node that has recipes starting with "C" or whatever hash algorithm.) That's a "SUM" type of problem. However, if you want to find the top 10 ranked recipes by links, the decentralized nodes can't answer that. That's a "calculate the AVERAGE" type of problem. Also, determining which webpages in the index are "fake news" or SEO "link farms" and other "bad actors" is also an "AVERAGE" type of problem. The machine learning algorithms need to see the whole index (or pedantically, a very large portion of it) to "learn" what "fake news" looks like.

Google's ability to comb their entire index in a centralized place lets them discover new insights to evolve the Pagerank algorithm from Panda->Penguin->Hummingbird->etc.[2]

Yes, you gain more privacy with decentralized or p2p search, but you also lose the ability to search on certain types of queries.

If the intellectual property of a bankrupt company would not be sold off to repay debtors, but instead, made public, it would be trivial to hire professionals to:

* Build you spare parts
* Perform repairs
* Enhance software

The latter needs to be enabled from the software side as well. Some security models etc might depend upon secrets. Those should be made illegal (false assumption that you can keep a secret anyway), and these releases should become mandatory.

This will hurt shareholders but greatly benefit all those that actually supported a company by buying their products. It greatly enhances the value of every product on the market.

Not working on a fintech but FWIW I work on trading platforms for a well-known investment bank. Getting in was not particularly difficult but even with some experience you may need to network with someone on the inside to get your resume in front of the right recruiter, simply submitting your resume via the usual channels appears to be a crapshoot (though I had never applied here because I wasn't aware they were in town)

My salary is quite average for the role/seniority level and AFAICT it's resented by many developers who work here because many will trade their "in" on their industry into more interesting fintech/banking work elsewhere somewhere down the line for higher compensation.

Knowledge of financial transactions is definitely highly specialized and I don't have nearly enough of it yet but it has started to sink in

Why do most/all electric and hybrid cars have regenerative braking while ICE cars don't? It's because, as the GP said, the battery would be quickly topped up and extra energy wasted. Only electric vehicles doing frequent stops/downhills can make productive use of regenerative braking.

Potential energy lost by a truck going 10 m (vertically) downhill: 40 000 kg * g * 10 m = 4e6 J.

Capacity of car starter battery: 40 Ah * 12V = 400 Wh = 1e6 J. Let's guess a truck battery has 4 times the capacity of a car battery, so 4e6 J to full charge.

That's just down one small hill and all subsequent braking energy for the entire trip is wasted.

At least some points he makes are true.

Battery tech

Tesla don't own any important battery technology or patents.

Main battery manufacturers are Panasonic, LG Chem and Samsung SDI. Panasonic is the leader and Tesla’s manufacturing partner, but LG Chem has made lots of progress and they are supplying to GM. Panasonic is rapidly expanding their own battery production is going to sell to other manufacturers also.

fixed cost and mass production

Tesla has no experience with large scale mass production (producing less than 100,000 cars annually is not big league). They have struggled with quality and delivery even with modest volumes for years, it will be harder when volumes grow.
They don't survive massive recalls if the quality is not improving.

They have to get Model 3 into mass production within a year or they will run out of money and investor's and customers patience. Nobody want's to wait years for a car. Roadster and Semi are just distractions. Tesla's future is on Model 3.

This will make debt more attractive for companies that produce something. At the moment the fact that leases are not visible drives productive companies to rent equipment instead of renting money. The big beneficiary were GE Capital and the like that in turn rented the money often at a discount. Leasing companies will continue to enjoy some economies of scale but have lost a strategic advantage. Any effect this rule change will have on companies will show up magnified in the leasing companies.
We are a culture obsessed by the how, not the why. A picture of people walking or biking to work does not fit our idea of the "future" as well as one where we ride around in slick glass pods. We have grown custom to doing even the simplest things orders of magnitude less efficient than they need to be.

We are also a culture obsessed by image and impression. Look at the image at the top of this article. Images of futurist cities like this drive me nuts, am I looking at a pimped up motherboard or a city where people actually live? What if a sustainable and livable city doesn't look very exciting on picture?

Cities are complex adaptive social systems that we are nowhere near fully understanding. Formulating a vision of a city with its base in a technological ideal ("smart") just shows how disconnected you are from reality and how setup you will be for complete failure.
If we wanted to make a low-maintenance, low-energy city, we'd use the LOWEST technology possible to get the job done. Round-a-bouts, not "smart traffic lights".

My personal view is that to see the cities of our near future, go to practically any big city in Asia today. High population density, everybody (whole families and and their farm animals) racing about on small motor scooters. Not a bad standard of living, but nothing like what we in thew west are used to (I'm in Australia).

Segways and flying cars are too expensive to make, too hard to fix, and too expensive to run. Ditto for maglev trains running in vacuum tunnels under cities.
> It’s basically a system for some filthy rich executive or other to show off, a virtue signalling of some kind.

That might be true in some cases. But the motive might be to provide epsilon demand to help develop a market for an embryonic product — in effect, making a small investment in which the hoped-for ROI in the long term is a "better" world — even though in the near term there might be less-costly options available.

That's why, for example, for years my household has bought our electricity under Green Mountain's wind-and-solar option, even though it costs a few dollars more per month (although the delta has been dropping). Our choice of electricity providers isn't visible to others, and it's not a subject of everyday conversation for us, so it's difficult to see how there's any virtue-signaling going on.

Ditto for why we bought a Prius years ago, even though economically a conventional vehicle made more sense notwithstanding the high gasoline prices back then. While we could be accused of virtue-signaling, I think it's more accurate to characterize it as signaling social acceptability, as in, "you won't be alone if you take the plunge and buy one of these cars instead of the usual [fill in the blank for your neighborhood]."

In math terms, you could think of this as trying to help the market to seek a long-term global maximum as opposed to a near-term local one.
My current one that I bought back in 2014 (or 13?) won't start up unless it thinks it has a network connection.

Otherwise it has an unskippable menu demanding to be given the wifi password (or hooked up over ethernet).

It is, mainly because people have very different ideas what "unique" actually is. At one time I had add the host of a page to their hash because people complained that if we hit the same content at two different hosts we filtered one out, which wasn't okay for political reasons.

The two first results in your example are "fun". That page returns different content with each call ... yay.
which is not by itself indicative of anything other than regard for your opinions on security? Really man? I get that you want to go to bat for dang here, but way to sidestep my point, I said quote "the proportion of the highest voted commentors that are pro labor or hostile to capital will be vanishingly small." There's a fair amount of semantics around what that could mean in practice, but one person, who themselves complains about HN social/political biases on twitter on the regular does not a majority make.

edit: not to mention I noted in my post to dang that there will be outliers, which, again, you clearly are at an internet forum originally and still largely dedicated to startups, a demographic slice not exactly well known for their love of labor rights.
