I agree with this sentiment. I'm currently pursuing a Bachelor's in Pure Mathematics (or called 'Theoretical Math', eventually I'd like to go far as a PhD in it). I think the ideas of Math could be taught in a condensed way. Maybe it's already done but...education needs to be disrupted in order to do this.

My current idea is that Math could be taught as a language and taught as a critical thinking class. A condensed class would like like 'this is an equation...here is what we can do with it (derivatives, areas/3D/4D, etc)...but...99.99% of you won't need to know it this way. You need to use math in a way that indirectly teaches you how to creatively look at problems in life.'

I'm not sure why everyone is forced to learn math without knowing WHY they are forced to know it. Creative problem solving is one of the best takeaways, imho, for the masses.

As for Adv. Math...I think it's not effective for most people's career paths and skillset they will require in the real world.

I wonder how much "proximity to a good hospital" changes it, as well. If I could zoom in far enough, and traffic can be assumed to be constant, would there be more fatalities on the remote parts of I-5?

Brunch is purely an asset build tool. Almost zero-config, very fast, older than Grunt, used for Elixir's Phoenix framework to deal with frontend so got a bit of traction recently.

Decentralized Ether Mixer (with a caveat)
Hi there! This thread makes me so happy. I posted the Quantum Supersampling video and then went on vacation for a week, and while I was out a colleague sent me this link. Thanks for your kind words; they made my day. The thoughtful smart discussion going on here is exactly what I was hoping would happen. I'll post answers (as well as I can) to the items here as time permits.

Regarding this one: You're exactly right that simulators can handle pretty complex circuits; my sim used in the video, QCEngine [1] will handle up to 28 qubits in a browser for full simulation, or many thousands for the subset of operations known as the "Clifford Group".

When I started scaling down things to run them, it was on actual hardware. Most hardware requires several 'physical' qubits to implement each 'logical' qubit. For example, the photonic chip I showed generated 4 entangled qubits, but the program I ran with it just has 2. It's using something called 'Measurement-based QC', whic destroys the working qubits as the program goes on. Anyway, the hardware's getting much better, and I expect to see photonic devices with many qubits in the near future.

Strilanc, your Quirk sim is amazing. It's fun and easy to use, and the tooltips on the instructions are awesome. The circle notation made me smile, as that's the way I visualize this stuff, even on graph paper.

A while ago I made some side-by-side notes on QCEngine and Liquid, as each is the right tool for a different job. You can see that here [2].

> As for quants not knowing VC - did they come from a dev background?

No, and that was the problem. The more you venture into this field, the more you realise how much of it is coding. New idea about how price series X relates to Y? No use unless you can pull the data, do the transformations yourself.

Another critical problem is that when you're unproductive, you make contortions to make your results "real". You make rationalizations that don't hold up, because OMG it's a lot of work to test some more ideas.
I meant Allwinner A64, not A20 (the A20 is Cortex A7 based).

Out laws are there for a reason: we want the state to run the intelligence service, not the other way around.

In single, extreme cases I can see occasional violations being tolerable. But here we're talking about systematic violations, which are not tolerable on any level.
>so that certain criminals that would never by caught playing by the book, do get caught.

we never get any evidence of this happening, so i'm going to say "citation needed". we also don't get any oversight regarding who they decide are criminals.

>Not all of us get to live in movie sets were the good guys always win at the end.

starting from the assumption that the intelligence agencies are the good guys is very much from a movie set... these agencies exist to effect the will of the state against arbitrary targets by way of power. there's no moral content there until they actually act.

Totally agree. But there is a difference between stable and dead. Bugfixes matter. Taking care of issues would mean that things like "FF 51 breaks the tooltips" (fictional example) gets discovered and fixed. And one or two improvements a years also don't hurt.
I would guess that it refers to someone who is a "true american", placing faith in a the military and a Christian God who blesses sex only within marriage. In short, someone who is more conservative.

Co-Founder of Renaissance Technologies Interview about Ensembling AI on Numerai
As someone that learned some math in university about 20 years ago, and probably have forgotten most of it, I have a hard time when reading something mathematical that interrests me today.

Maybe the authors of the papers that I read aren't always that pedagogical, and I get totally lost when someone tosses in a variable only to half-heartedly define what it is a page later.

I think it's mostly due to that I suck at math, and need to figure out obvious things on my own - but perhaps also due to my programmer-view of the world were you typically define things before you use them...

But learning on your own is probably hard. I got irritated once when I needed some not totally trivial transformations for a GIS application. I spent some evenings repeating from my old books, but it was unfathomably boring, so I gave up as soon as I got my transformation working :-)

Disagree.

First off, we now have Controllerism ( see: https://en.wikipedia.org/wiki/Controllerism ).

Controllerism can be vastly more complex than Turntablism, requiring custom software and several input controllers.

Second off, digging for digital tracks is just as hard ( if not harder ) then it use to be digging for vinyl tracks. There is so much new digital music available coming out everday, that being able to dig out a good not-very-well-known track is like finding a needle in the haystack.

Are some DJs simplying hit play on a Top 40 tracklist in Traktor? Sure. Does that mean the art form is dead or doesn't have room for vast improvement? Not at all.
Hah, I hear you! It's barely been 2 month that I got started with Webpack/React. Gave me a pretty hard time, learning all it's quirks... specially the way it handles CSS. And seems there's something new on the block already!
To clarify because I nearly skipped over this video thinking it's about those two:

The video actually explains what browserify/webpack do, as well as what rollup brings to the table. I don't think it covers brunch, however -- maybe I missed it.

One way this might be useful is in trying to communicate with whatever world is simulating us. I think in some circles this behavior is called "prayer". Of course, it could be that explicit communication (in a way we'd understand) is strictly forbidden, such that we would never receive objective confirmation or rejection of this theory. At best, we could prove the plausibility of the claim by doing our own simulation. How each chooses to spend their time is up to them.

Maybe it's like that where you work. But if I was the BA and was having to be personally responsible for something I would want to make sure that what I was specifying was actually correct by discussing it with the people who will be doing the work. Because that responsibility cuts both ways.
> DJing has always been about selection, and crowd reading.

Splitting hairs, but there's an assumption there that you're trying to react to the audience, often intending to please them. Coming from a background of DJ's playing "difficult" music, sometimes the audience's reaction is incidental.

How difficult are we talking? Breakcore? Free jazz? Sound art?

I reckon the trick is in pacing the set and planning your first two or three records to keep most of them on board. If people have paid to get into the venue they must be at least a little predisposed to like what you're playing, and ideally you should be able to keep people dancing against their better nature.

Of course clearing the floor and then drawing them back in is always good too.

If you really don't care what they think then IMO it's perhaps more into the realm of performance than DJing. It's a tricky one.

Sure, I've written a book "Social Architecture" on this, and many articles. You can read the book freely at https://www.gitbook.com/book/hintjens/social-architecture/de.... It's also in print and Kindle from Amazon.

The psychology of collaboration is (in my model, which is of course wrong, just accurate enough to be more useful than ignorance) based on emotions that we've evolved to work together. Most of what I tested and documented over the last decade came from study of failure (most projects fail and you can learn a lot by looking into why), and experience of how to make communities that could survive the kinds of conflict we see. Actually getting a full model for the emotions took a lot longer, finished that a year or so ago.

Not always. Also, there seems to be only one audio track per product, so e.g. "Mr Robot" and "Mr Robot [OV]" are two different products (you can't just switch half-way through an episode like you can with a DVD or Netflix). This is possibly infuriating if you actually rent/buy a TV show and find out you either can't keep up with the original voices or the dubbed audio is unbearable.
Even if anyone could be a DJ, which is doubtful, not everyone can be a good DJ, and certainly even more so some people would be better more creative dj's.
That's remarkable.

That's sounds typical for a graduate course in the US and atypical for an undergraduate, even an advanced undergraduate course. Most assign problems from texts and will have one or two texts that are required or possibly strongly suggested to have. On the other hand, many students don't really read the texts except for the questions. In graduate courses there are usually just a few suggested books you could use if you wanted to.

The title itself implies a kind of answer. If you boil the question down to art: "anyone" has been able to do art for a very long time, and art is not dead. So, for any particular art form the same might be true.

Seem to me when more people participate in an art form, the art form will evolve and become more diverse.

12 Tips for Building a Great Website – The Road to Business Success
DJ-ing with decks has died. DJ-ing lives on. 1210s are no longer made and although there is plenty of vinyl out there, it is not the same. Not the same? You cannot buy new stuff on a constant basis, you don't have friends that only know vinyl and times have moved on from the 90's. People have got older.

Incidentally CD came along earlier than the article states, standard equipment from the early 90's with lots of beatmatching gizmos.

DJ-ing was an analog skill. Original early dance music was analog production of digital instruments.

Kids today are using digital technology for the whole chain of music creation including DJ-ing.
The only argument that Rowe makes for the desirability of skilled-trade jobs, at least in this piece, is the job security they offer:

>> As long as Americans remain addicted to affordable electricity, smooth roads, indoor plumbing and climate control, the opportunities in the skilled trades will never go away. They’ll never be outsourced.

Of course "a whole category of good jobs have been relegated to some sort of 'vocational consolation prize'" - they're good jobs, not the best jobs. They don't pay the best, they don't offer the best working conditions, and they don't signal the highest levels of social prestige. That's simply a function of the other possible career choices that exist.

Ambitious people aspire to the best. Parents want their kids to have the best. The biggest problem I see is that society and the increasingly winner-take-all economy make it easy (and often economically rational) to feel like anything but the best is a failure.
Sure if we develop some kind of voracious habit of cracking processors open.
Ha! Thanks.

I re-read the author's paragraph. On first read, I thought he's using alight in the sense of "lighting." In that case, it's not a verb. I assumed this because even show DJ's who are "just pressing play" still touch the dials. It's just that the board isn't plugged in.

edit: it appears there's a non-OE meaning that I overlooked too [0] from mis-interpreting the text.

I should add, for a mathematical audience, I'd be careful, because of possible confusion, and insist on saying positive integers, and non-negative integers in the case of what I'd call the natural numbers.
Hah! Plain white bread is clearly where it's at!
I don't think that's quite true.

When I first started in the early 1990s, it was pretty expensive to get into as a hobby. I could have been fairly economically comfortable in my college years, but was constantly making myself broke by pouring every dollar I could spare into records.

The flipside of this was that the people who did take it up tended to be serious about it. From time to time there would be some rich kid who would blow a few grand of daddy's money on gear and music, declare himself a DJ, and then get bored a month later. For the most part, though, the financial burden meant that new arrivals would take it seriously and were interested in improving.

As CD decks and CD-Rs became common I thought we'd see a lot of fresh talent from people who wouldn't have been able to afford starting out when I did. Instead there was a flood of people who just wanted to call themselves a "DJ" but had negligible interest in learning much about their music genre or developing any technical skills. Instead of stronger wheat, we got buried in a ton of chaff.

The other underappreciated change was to how clubnight promotion works. In the olden days, the promoter would take care of making flyers and getting people in the door. They'd seek out DJs that they thought would keep this crowd happy. So as a newb DJ, if you would work yourself up the ladder by impressing the local promoters and developing a good reputation with them. They would provide the crowds that you'd make your name with.

Today, with effectively all promotion being done online the biggest thing that a rookie DJ can bring is a built-in audience. There is a huge advantage to the social butterflies of the world, who can now effectively self-promote their appearances to a wide circle of acquaintances, saving the club promoter work.

That might seem like a small shift (or just sound like sour grapes from an old geezer), but it has been a striking difference in who gets started. For a long time a lot of DJs fit a certain archetype of music nerds.. often the most introverted people at the nightclub. Once when I met rookie DJs I felt like I saw a younger version of myself in them. Now I don't get that feeling... it's just a different set of people who take it up.

It's certainly possible that there could be a renaissance. The technology available today lets DJs do live manipulation that the best turntabilists a generation ago couldn't have dreamt of. However, I'm not optimistic -- I think that realistically 95% of the people showing up simply don't care about what part of the process is being done live. I think increasingly clubs are just going to move to playing livestreams or pre-recorded sets and avoid the cost of an onsite DJ entirely. As long as people still show up and buy alcohol that works fine for them. I think ultimately the notion of a nightclub paying someone to haul in music, select what to play, and mix it live will be an anachronism.
Seems that would only be an issue during manufacturing and disposal. CPU manufacturing already deals with hazardous materials, so that should not be a huge hurdle. On the disposal side, the hazard could be reduced by stepping up efforts to recycle old parts.

Definitely something to be wary of.
