It turns out, though, that those few problems are pretty common.

FFT is O(d log d) classically, and O((log d)^2) Quantum mechanically.

Gaussian elimination (used to find eigenvectors and eigenvalues) is O(d^3) or O(s * d^2) for classical (non-sparse and sparse, respectively) versus O((log d)^2) for Quantum.

(And similar speed up for Matrix inversion.)

FFT? Matrix inversion? Gaussian elimination? Super common. And in the case of Gaussian elimination, it gets pretty hard pretty fast.

You're right that we still have to scale with proper error correction, but the fact that quantum error correction is possible is very good news for the future of quantum computing. And the best, ~50-bit quantum computers are approaching what is needed for a fully error corrected qubit, although proper connectivity needs some work.

So you're right to be wary of the current status of quantum computing, but I think you're wrong about Moore's Law, here. Qubits can be and are made with photolithographically scalable techniques today with error rates that approach what's needed for error correction, even taking into account some of the problems that integration causes for integration. And, in fact, error correction is what enables us to scale quantum computing (although there are still some calculations we can do without error correction).

I do think we're pretty close to a threshold, here, with quantum computing. We are probably under one or two years away from "quantum supremacy," if you accept having a quantum computer too sophisticated to reliably simulate classically.

We aren't 3 years away from breaking encryption using Shor's Algorithm. We're probably at least a decade away. But there ARE a bunch of uses for quantum computing that don't require as many qubits. A few hundred physical qubits is still enough to do things that wouldn't be feasible with classical computing.
That was my path as well. Pretty much every smart, working class or middle class student at my high school picked engineering or science routes. Unfortunately many of the science routes led to academia, which everyone I've talked to seems to hate from a financial perspective. Of about 5 people I know personally, all but one has dropped out and picked up a mostly unrelated jobs or research gig.

I went back and checked LinkedIn for some of my old HS people, and it's interesting how different that patterns are. The children of doctors are doctors or lawyers. Some of the really motivated children of first-generation immigrants ended up equally successful though. Both groups tended to go to private institutions though.

I wonder if the difference is how risk is evaluated. Middle classes see hard sciences and engineering as reliable, accessible, career paths that minimize risks of joblessness and allow them to leverage existing connections by staying in state while studying (since most working and middle class folks have a family support structure local to the area, also in-state discount) without burdening their family more by picking a field where paid internships are rare.

Meanwhile, richer folks are not worried about needing to work while studying, and they don't need to stay in any one place, especially if the careers of their parents gives them connections to in-demand places for jobs and study (or maybe money just makes connections unnecesary).

Every once in a while you read something where there's a statement that so epitomizes the content, and seems to resonate so closely with the author, that it's obvious that what they are doing is presenting one of their core beliefs. And not just core as in "I strongly agree" but core as in it's become integral to their way of life and how they perceive the world.

Those are interesting pieces, as whether you fully agree with them or not, they are generally well thought out, as the author can and has put quite a lot of time into thinking about the subject.

First, I was curious to know if Google ripped this guy off. I could only find his song (https://www.youtube.com/watch?v=wdM4zNN-PxU) not the Google ad. But, as a (amateur) musician myself, I don't think there is much to the chord progression. It sounds like a thousand other songs - the lyrics and delivery are what make this song unique and good.

Second, incredibly well-written. Very persuasive.

Third, it's been clear for a long time music was going to only get harder to succeed in, for the sole reason that as time goes on you are competing with the entirety of music history. Your recorded music is competing with everything ever recorded, Beatles, 80's glam rock, Mozart, and rain forest nature sounds. (Live music has magic, yes, but people are getting immune to it.)

Fourth, the 60's-00's was a golden era where technology made it just barely possible to record and distribute music, in a way that required a lot of labor. That labor made it more collaborative, and served as a kind of distributed gate-keeper to the market. Now, technology is too good, and unless an EMP pulse from a solar flare or nuke destroys all digital recordings of everything, it's not going to turn back.

Fifth, I think the solution is to embrace and extend the modern trends. Get people to collaborate with you on stage using their cell phones. As a performer, connect your phone to the PA, then run a webserver that people in the audience can access over the local subnet. They can then affect the sound in arbitrary ways (perhaps most simply by making beats).

we're just being good Strunk-and-Whiters and omitting needless words.

What if the title was 'The Greatest Show on Earth'?

The two titles have a slightly different flavour - calling one linkbait is silly (hyperbolic, even!), as is claiming this is being 'good Strunk-and-Whiters' (beside whether 'Strunk and White is really that great a writing standard to begin with).

HN editing leans strongly towards desaturating, flavour removal and tone flattening. That's fine, but it's a preference and you should own it as such - it's not some sort of stylistic virtue. Nothing awful would have happened if you just left in the original. You just didn't like it.

The US used to restrict branch banking across state lines. Before that, savings and loans were restricted from lending to projects more than some distance from an office, as they were expected to go out and look at construction. Now, the US has four big banks.

This is allowed by deregulation, and practical because of the Internet. Banks don't need lots of little branches. But their customers did.

Most of the little guys did not get in trouble in 2008. They did fine and didn't need bailouts.
It’s apparent that a lot of HN readers do not like my work on the basis that they see me as a shameless Apple shill, but it’s a shame the articles get deleted because I like reading the comments. I feel like it keeps me on my toes to read the comments from people who don’t like Daring Fireball.

"Why? To me this is no different than a person who is against mass murder being okay with multiplayer first person shooters."

I'm not sure it's an apple's to apple's comparison. Multiplayer first person shooting games are designed for mass killing. Minecraft players are playing a game to gather resources to build things. Alice is playing a economic simulation. Obviously she is going to win.

The equivalent analogy would be that Alice gets on to a Counter Strike server, and somehow manipulates the economy where she gets the best guns and all the other players get a knife. IMO, the game will not be fun for the vast majority of the players.

Obviously, the consequence is minimal compared to losing a meal. The only real consequence is that the perpetrator is a big bully and an ass. In real life, we (as a society) would look down on an adult who went to the playground and kicked out all the kids. There are no real consequences for kids to not play in one particular playground, but that's not the society we want.

It’s interesting to see the swing of the valley — from military-industrial tech to consumer tech.

You either need more people or less work. And having too much work may be because the organization has lost focus on what really matters, and is trying to do everything. You cannot hire enough people to solve that problem, because as you add people, management says "great, now we can do even more..."
> Football is a sport that is designed to really allow people to showcase the limits of the human body.

Not really; depending on dimension, gymnastics, ballet, marathon, short-distance sprinting, powerlifting, and any number of other sports and physical arts are far better at showcasing the extremes of what the body can do.

> The most impressive athletes in any sport in the world are in the NFL

Well, “impressive” is subjective, and all this really says is that you are particularly prone to being impressed by the kind of display that the NFL provides.

Couldn't you taint the crytocurrency?

It wouldn't be exactly something that can be done overnight, but it wouldn't be impossible. Depending upon how strongly they implement the laws, it would kill currencies that don't offer protection from being tainted.
On the other hand, if you feel you are a top performer and want to work with other top performers, you wouldn't want to work at a place with mediocre developers.

Marxism-Leninism is certainly not dead, although the fall of the USSR was a harsh blow. In my Western European country, the Communist Party still gets almost 10% of the votes, and while they no longer openly defend Stalin's legacy, Leninism is still very much at the core of their identity.
Yeah, would be interesting if you could somehow make it easy to figure out who would make a good fit.
Another thing - you could sell music (ie. records / CDs) at gigs. You can still just about do that but probably not for long, at least with most markets. A small independent band will likely make more profit on a single CD sale than they'll ever make in downloads.
>Weren't the Bolsheviks just a minor faction that ended up winning the civil war? Bolshevism became the party in the USSR.

Nope. It was a majority faction ("bolshevik" literally means "member of majority" as opposite to "menshevik", "member of minority") in the Russian Social-Democratic Worker Party (РСДРП). They took power during the October Revolution. Soon after the revolution the party was renamed into Russian Communist Party (of Bolsheviks). A year later the Communist International (Commintern) was created by Lenin's order and its first congress in 1919 was attended by delegates from 21 different countries.

So, it seems to me, it was not a minor faction in a single country but a member of the international Communist movement.
I wouldn't count on that. Battle-testedness can be a feature, and a new software package means new training for those tasked with maintaining the system. The old one is a known quantity.

It's not that bad if you don't need an exact answer. Just convert to metric, multiply it out, and convert back.
Because Web browsers originally operated under a document-focused paradigm rather than an application-focused paradigm. (The CSS box model spec makes much more sense if you dig through it with this in mind.) Even after Javascript came out, there wasn't really a notion of a Web application in the modern sense- if you wanted to deliver rich content, the primary way to do it was via Flash or Java applets. I would hazard to say this was the case from around 1995 to 2005?

Anyways, I think the demand for more sophisticated layout systems didn't emerge in earnest until browsers started to experience the paradigm shift from "dynamic text document renderer" to "application runtime environment". If I had to put a date on it, I'd say that this happened during the 2005-2007 period, during which we saw the first big wave of Javascript libraries (including Prototype, jQuery, and MooTools), as well as the launch of the original iPhone _without_ Flash support.

As for the length of time it's taken to release Grid, it looks like W3C has at least been aware of the problem for quite some time- the first "Advanced Layout" Working Draft was published in 2005, but it looks like it didn't stabilize into the current Grid layout until about 2015.
This is a copperhead.

Probably not this. 640k was actually the maximum amount of memory available for a user's DOS applications on an IBM PC or clone. There were many PC's sold that had only 64k of use-accessible RAM. It was only in later years, as memory got cheaper (and apps "ballooned") that machines maxed out at the 640k limit. With the 16-bit system the actual CPU-addressable limit was 1024kb (or 1MB), but the difference was reserved for use by the system for things like the ROM BIOS, graphic adapter bios, etc.

My memory is vague on this, but I believe the core DOS commands (e.g., copy) were part of the ROM BIOS (or maybe they were just always loaded into non-user-accessible RAM as part of boot). So they were always present and did not affect available user RAM. The non-core DOS commands (e.g., xcopy) had to be loaded into user RAM to run. What's more, if you had a diskette-based system (i.e., no hard drive), you would have to load the floppy diskette that had the particular extended DOS command you wanted to run, before you could run it (because it had to be read off the diskette).

You are right, it isn't a perfect metric, but it is the best one we have until further studies are done about sub-concussive hits. Measuring hits like that would change the relative rankings of the each sport (soccer probably becomes more dangerous while baseball less so), but the overall point still stands that most sports involve some risk of head trauma.
>It’s all different now. My own observation of the current music industry is colored by my history with the extinct model. I can’t begin to imagine what it must be like to come up in this world of SoundCloud rappers and Swedish hit factories churning out auto-tuned EDM or whatever. Believe me, I’m keenly aware that even these two meager examples must make me sound impossibly old. My point is that if I was a fourteen-year-old depressive nowadays, I’m not sure what would even draw me into the world of music to begin with.

Not much. And indeed, kids todays are much less invested in music than kids where in the 60s till the 80s or so.

For one thing, there are now tons of competing outlets that weren't around then: tons of movies of all eras available (and most current top-tier movies made for teenage sensibilities, less All ), great TV series with huge production values, Netflix and co, YouTube, Twitter, Snapchat, Facebook, the web at large, texting, computers, mobile apps, and games.

Besides, there's less mystery in music acts (total transparency and 24/7 social media exposure for any fan who cares who check), less exclusivity (all music available on online services), and less ubiquity (each act gets a much smaller of the attention pie, and can even have a top-10 hit nationwide that half the nation haven't even heard or knows -- something impossible when there was huge radio and only a few TV stations and outlets and hits were hammered constantly without other recourse to everybody).

A well aged wine is usually not a bad idea if you have some money.

In a deep crisis, cigarettes aren't a bad idea, they usually end up being a black market currency. In other regions of crisis bullets might also be a good idea.

For a proper financial market with money, a good store of value might just be a long term savings account in a bank, that's a very stable value store and usually those keep up with inflation pretty well. If you can have a bit more risk there are index fonds and ETFs but those are more money making than store of value.

In places with weak economies it usually doesn't make sense to establish much of a store of value, bartering is more common and people just live with what they have, the accumulation of wealth beyond the daily necessary can be rare in some african countries.

BTC is also a bad solution since it's rather expensive, weak economies have more people who can't afford the rather extreme transaction fees (which are laughably high compared to EU SEPA transactions even at comparable confirmation times)
> bitcoin is hardly easy to obtain in that situation either.

It's def. easier than getting US T-Bills. BTC is widely available in most countries and if not, you just go to a meetup and trade it in person (with higher fees but still easier than... US T-Bills). So, you still owe us after all this discussion a better alternative for an internationally available store of value than BTC.

I suspect the author is trying to persuade those who make 'very anxious responses from people in tech at anything which suggests that their “core skills” may be devalued' and the reason I feel the tone is disrespectful is because he shows very little empathy for them. On the other hand, perhaps instead the point of the article is to reassure those with the soft skills that they will soon be more valuable than they currently are.

I think what he was going for was that you shouldn't solve the overworked problem with hiring. It indicates you need more manpower, yes, but it's also indicative of planning and resource allocation problems that need to be solved first. Adding more people before you solve those problems will probably make things worse. Things need to be properly divided and conquered, some things may need to be put on the back burner. It often indicates that you haven't split up the workload into manageable pieces, and are instead trying to get it all done at one time.
