I don't have time to thoroughly read this before commenting, but upon scanning it, I echo the disdain of many of the other commenters. The lack of humility seems to reflect the lack of important prior work cited in the paper.

Most glaringly, the author assaults Helmholtz without acknowledging the fact that people who study this topic in academia are way past that. It's like if I were to tell you that I've got an amazing new theory of physics and justify it by referencing Newtonian mechanics -- every academic knew it to be incomplete a century ago. Pointing that out is not a novel idea.

If you're interested in understanding how music works on a psychological level, "music theory" is the wrong thing to search for. The fields you're interested in are psychoacoustics and music perception.

Music theory is the study of compositional practice. It's a field that collects a whole bunch of descriptive theories on how composers in different periods and genres tend to work. You can use it to help yourself compose pieces in a given paradigm.

Psychoacoustics and music perception are the study of how we actually understand sound and music. The theories therein are what gave us things like lossy compression (e.g. "exactly what raw sound data can we discard and still preserve a perceptually identical recording?"). This is an incredible achievement in that it only works if we have a thorough understanding of how the brain processes sound and music. Psychoacoustics has little to say about what makes something qualitatively musical, but that's where study of music perception picks up.

In the overlap between these two fields, there are a bunch of people working on unified theories of harmonic/Western/tonal music. The author fails to reference the most interesting work done in this area. The ones I've found most convincing are:

- Dmitri Tymoczko's Geometry of Music: http://dmitri.tymoczko.com/geometry-of-music.html

- Bill Sethares's Tuning Timbre Spectrum Scale approach: http://sethares.engr.wisc.edu/ttss.html

- Andrew Duncan's Combinatorial Music Theory: http://andrewduncan.net/cmt/

Some of this work is pretty old at this point. Granted, it's surprisingly difficult to do a full literature review in this area. I know from experience, because I studied this topic in grad school. Someone could probably earn a Ph.D. by properly synthesizing all of these idea into a music theory that combines the analytical power of Tymoczko's approach with the first-principle work of Setheres.
That sounds like a morally questionable attitude. Like people selling drugs or weapons. "I'm just selling the stuff, whether it's good or not for my customers is none of my business".
If they are targeted at the education sector, as in deployed in schools, they should be MORE repairable. Students wreck stuff they don't own.

For instance, latest (non-Pro) iPad went back to a more repairable chassis that educators are liking because the screen is much easier to replace. And Chromebooks are so cheap if they break it's not a huge loss.

I don't think the Surface is particularly targeted to edu enough to alter their hardware assembly decisions though.
Doesn't look like there is much of a choice. I wonder if this was a design or a business decision. I could imagine a lot of cost could be scrapped by not having staff and repair facilities.

This is such a frail argument in my opinion. Have a look at Dubai for an example of what humanity is capable of when we put our effort into something. If we truly wanted to, we could colonize any area of the planet. We just have no real motive to do so. Colonizing Mars is just the next step for our species. It's going to force us to tackle some really, really big engineering and civil problems, but we're going to eventually get there because that's what we do. We explore and we create new civilizations. Always have, always will.

It would be worthwhile to simply have an organization so that when shitty things happen, you don't have to try and form one while simultaneously dealing with shitty things. A union is like insurance in that way. You get it when you're healthy so that it'll be there for you when you're not.
Seems like the idea was "Whole Foods as a commune" i.e. viewed as a commune. In other words a conceptual lens through which you could view any organization. Amazon itself is a commune in some ways, and so is Whole Foods; therefore my two examples. in history. are Amazon and Whole Foods. So much for that.

And looky there, other commenters supplied a bunch more (actual) examples. I'll throw in: The Catholic Church. The nation of Yugoslavia. What the heck: the Hell's Angels. Far outstripping Amazon's "scale" in terms of heads smacked with wooden fenceposts, that's for sure, or maybe not.

Which is my next point - adjust the "scale" appropriately (and unfortunately you left no indication RE: scale of what, whether it be dollars in sales, people involved, people served, ham sandwiches set aflame, heads smacked, or dogs painted blue) in proportion to the amount of money/wealth existing in the world at that time. in history. or to the number of people alive at that time. in history. and that'll probably turn up a bunch more examples.

There's also the question of "successful at what"? At providing for its employees/members? At serving its customers? At enriching its shareholders? At painting dogs blue?

Also we should really make passing mention of the waxing and waning support for capitalistic enterprises vs. other types of communes in various places and times. in history. Is it a valid comparison between a company like Amazon, operating in one of the most capitalism-friendly sociopolitical environments (post-Reagan America) seen in some time, vs. another type of organization operating in the same environment that doesn't support that organization or even actively suppresses it?

One meta comment.

You've taken the usual approach of explaining matrix operations as an unmotivated "this is what we do" and then tried to layer linear transformations as a weird abstract thing which somehow relates. Most people do this, and it makes sense for people who don't want to actually understand.

If you want people to actually understand, the relationship goes the other way. Linear transformations are the thing we really care about, and matrices happen to be the most convenient way to write them.

More specifically if T is a linear transformation from V to W, with bases (v_1, ..., v_n) and (w_1, ..., w_n), then then we can write down M = (T(v_1) T(v_2) ... T(v_n)). So far that's just a rectangular array of numbers, uniquely defined for the linear transformation. Now if we have a vector v = a_1 v_1 + a_2 v_2 + ... + a_n v_n then just tracing through linearity, we get that T(v) is Mv with the regular matrix multiplication. Furthermore we can now prove that any rectangular matrix defines a unique linear function with that rule.

The result? When you have 2 vector spaces with a basis for each, each linear function gives a unique matrix, and each matrix gives a unique linear function. Matrices are just convenient ways of writing down linear transformations.

OK, now if S is a linear transformation from W to U, and we have a basis for U, then what about the function S o T defined by S o T(v) = S(T(v))? If you work it out, it is a linear function, and its matrix is the usual matrix multiplication. So matrix multiplication is the same as function composition for linear functions.

Here is something fun. You know the associative law? That magically just works after a ton of calculations for matrices? Well, here is why it works. For any three linear transformations R, S, and T which can be composed, and any vector v, by definition:

((R o S) o T)(v) = (R o S)(T(v)) = R(S(T(v)))
(R o (S o T))(v) = R((S o T)(v)) = R(S(T(v)))

Which means that functions under composition are associative. Since matrix multiplication is just a way of writing function composition, it must also be associative. QED!

As you move through things like change of basis matrices, it is all a lot easier to understand starting from the point of view of linear functions as being fundamental, and matrices just being a way to represent it with a given pair of bases.
Maliciousness probably costs money, and Amazon's looking to spend as little as possible on these warehouse resources.
At least in the UK, I've never been unable to sell or give away an old laptop, even if it's "broken". There's always someone willing to repair it, whether a student with plenty of time, or someone who runs a small repair shop and buys broken electronics from eBay to repair and sell.
The Surface laptops, perhaps with the exception of 2012's Surface RT, have earned generally positive reviews, with critics variously commending Microsoft (Microsoft!) for designing attractive-looking hardware that doubles as a reference point for its vision of what a modern Windows-based laptop should look like. Unfortunately for consumers, this seductive vision is apparently incompatible with being able to extend the laptop's useful lifespan on your own

This 'seductive vision' is also a direct assault on the consumers right and prerogative (once taken for granted) that he(she) own and do with as he deems fit, any item purchased with his money.
First, the abominable Windows 10 which is a brazen intrusion on users privacy; now the Surface. What else MS ?
I'm just saying they should still have something to do. There's plenty that needs to be done.
Yep, there's a lot of category error that gets introduced when using words like 'computer', likely far too much for legislation to handle correctly. We've got more form factors than ever, there's a lot of fluidity between them, and the traditional 'computer' market is stagnating anyways.
Surface and MacBook are not marketed to those people. They haven't been marketed to those people since the removable battery was killed off.

I remember getting a french breakfast in London and then eating what seemed like "black soggy bread". It was Boudin. Gotta translate those entrees BEFORE choosing them.
In all seriousness, would this be a good candidate for using as a sort of "dummy" travel laptop? I'm thinking of something along the lines of sealing off the ports too. That way, if intercepted or taken for "inspection", there's almost no chance that it could be hacked by physical access without leaving obvious clues.
I think nobody can deny that, all other things being equal, short-term occurring events tend to matter more than long-term ones.

Therefore, no matter how bad one can feel about the prospect of humanity being wiped out, that feeling can be made arbitrarily low by delaying the expectation of its occurrence.
So what? Upgradeable or replaceable devices prevent a LOAD of electronic waste.

Common stuff that breaks on phones: screens, USB jack (hi Samsung, I managed to break EVERY USB port on my 5 Samsung phones so far), 3.5mm jack (hello pants dirt, my old friend). Worst phones are these where the USB port is soldered directly to the motherboard and not a cheap daughter board - next to zero repair shops have a solder reflow oven or the necessary skill to operate one, and it certainly doesn't help that there seem to be thousands of different versions of a micro USB jack.

Common stuff that breaks on laptops: keyboard (hi coffee, hi fat cat), HDMI jack and especially power jacks.

Both get hit by batteries going bonkers - I had a couple of laptops with swollen batteries, and I'm happy I still have a phone with a replaceable battery, been through two batteries now.

Having to throw away a (possibly) 1500+ € device because COMMON parts, that cost CENTS, cannot be serviced, is beyond ridiculous.
You're missing the point. There's room for social programs to get these things done, but UBI for nothing isn't a good idea.
That's a very fair point. Maybe what those people need is a laptop that looks more like the ones we had 15 years ago that are larger, and easier to manipulate. However, the universe of people who will get rid of a laptop once it stops working is large enough, that a company can be very successful addressing just those people. Maybe the answer to your statement is someone needs to make low cost laptops that are thick, heavy, cheap, and maintainable? The problem is whatever company that is will not be marketing themselves as "cutting edge".

> a base living wage without work does not a happy life make

Makework doesn't cut it, though. You can hire a guy to dig a hole and another guy to fill it in, but both of them will be utterly demoralized. And I have trouble believing garbagemen wouldn't be happier staying home even though they know they're doing necessary work.
I mean the combination of format string + values.

Anyway, is that really true? "%-1s" should probably give you an error, for example.
Honestly, like 95% of people.

Practically, even if Microsoft did want to make the device disassemble friendly and was even willing to spend the engineering dollars to make that happen, I think they'd be turned away by the fact making a "polished" device that's easily disassembleable would increase failure rates. The bonded materials greatly increase strength over a set of spaced screws/latches into thin material.
I remember being a poor student in the 00s, looking for hosting providers and Linode was a new cool kid on the block (prohibitively expensive for me though). Now a lot of things changed, and I can easily afford a VPS now, but Linode is still around and still is one of the better options. DigitalOcean is basically twice as expensive.

Thanks for your detailed reply. You mentioned:

>"You can either map the whole kernel into every process's address space of you can map a small trampoline that switches to the real kernel's address space and flushes the TLB every time you enter the kernel"

Do you know what OS's employed the "trampoline" option instead of the more common mapping the kernel into every process address space? Were these commercial UNIX vendors maybe?
Walmart does something similar. I recently bought a generic desktop power cable from them, which when I checked online was listed at ~$5. In store, it rang up as $20. They price matched, but it's kind of ridiculous that they're preying on consumers like this.
They do in my case.

To answer your question about MacOS 9 comparisons, I meant technical limitations, like single threading issues, ui capabilities, you know. I may be wrong, though, I haven't paid attention to Emacs intervals for a while. Modern web-based platforms are far from perfect, but they are reacher.
You can't eat your cake and have it too. Sleeker, smaller, thinner, cheaper, MOAR BATTERY.

That's what the market wants. If the market wanted ClunkBox perpetual computer that was infinitely upgradeable, there would be an option out there.

They probably also use Outlook. That's what I do (4K employees). Used to use Mutt almost exclusively, but just became too hard and people complained about my emails turning everything to Courier. :)

I still use Mutt to quickly prune emails in the AM and for writing to mailing lists.

I've (sadly) gotten pretty used to Outlook and like it quite a bit. I do miss using vim to edit emails though...

As much as I kinda loathe this tendency, like the ways most people treat phones, these "luxury"-style laptops like the Surface and MacBook brands I kind of assume to be as-is.

Most of the people who can afford to spend that kind of money on a high-price laptop with mid-range specs are the sort to buy a new one in a year or two anyhow.

If someone's looking for a computer to last them a number of years, I generally wouldn't recommend a Surface product. A mid-range Acer or Dell is not as pretty or thin, but is going to be easier to repair and upgrade over time.
I thought it was relevant. Alcantara is a new material in computers, and we don't yet know how the wear will be.

The video describes the wear on a steering wheel, which seems comparable given its also something the user puts their hands on to interact with. As we know, hands are dirty & oily, and thats one of the biggest challenges in choosing what materials to build a computer out of. See ABS vs PBT vs other plastics in the mechanical keyboard world - people care about this.

The video at least gives us something we can look out for. There may be a wide variety of Alcantara types out there that wear differently, we don't know though.
