It has not been shown that it solves QUBO/NP hard problems any faster asymptotically.
That’s overly simplified and missing the point. You can buy a 880 home for 90k in Gilroy CA just 52 miles from Stanford. In much of the country you could travel that distance daily, but because the roads are so overcrowded it’s still cheap. I am saying the exact same thing happens just a little bit closer whenever you build higher density without building new infrastructure to support it.

Now sure like most things there is a density sweet spot. But nobody is building suburbs because their close to corn fields. It’s still the cities infrastructure that’s driving up land prices around it. Simply because that land happens to be near stuff people want.
I would prefer this to any cash back scheme they can cook up. I would rather the card company didn’t take a significant share of the purchase and run as lean as possible. I’m sure that I am in the minority viewpoint here though.
Yes. That is my point. I meant that it is not a general purpose quantum computer.

There is no general purpose quantum computer that has 5,000 qubits. The D-Wave machines use quantum annealing. My reference was to the probabalistic gpc algorithm for solving TSP using annealing.
They have a declining population, which I imagine helps.
My biggest issue with that is I don’t think it helps. Putting people in places they can’t compete doesn’t work.

I’d even claim it a national security threat in that its vital our smartest kids get the best advanced training as it should benefit us all. Letting average or above average kids into places meant for the best of the best doesn’t help.
Agreed. The cost for underwater tunnels will be much higher - especially initially. Let's say they are 100X higher cost at $100mil/mile - that is still 1/30th the cost of a current tunnel in San Francisco at $3bil/mile. But the Boring Company is already designing for air tight tunnels: 'vacuum-sealed'.

"TBC’s current tunnels are designed and built in preparation for their eventual transition to Hyperloop."

"Hyperloop is an ultra-high-speed underground public transportation system in which passengers are transported at 600+ mph within a vacuum-sealed tunnel. Whereas Loop is used for shorter intra-city routes, Hyperloop will be used for longer inter-city routes."

You can’t just buy the machine like any other COTS product. You typically need a team of PhD scientists to operate it as well.

I think D-Wave has also gone the way of providing it as a cloud product with their ‘Leap’ service.

It's something like $2k for an hour of processor time, which is a lot of submitted jobs. You can sign up for free, and I think they have credit card transactions, so no, it's a bit more direct than all that.
I believe in quantum computing in the long run, I took some graduate math classes on the subject in college; I'm at least passingly familiar with the principals, so the following isn't really coming from a totally un-informed perspective:

With regards to the D-Wave systems in particular, are these actually faster than solving the problems with a classical approach? There's no benchmarks, no numbers, nothing -- just a customer list. A customer list whose engineering offices want to look hip. I mean, VW, Accenture and Save-on-Foods? I can't help but feel like if it did anything even a hair better than classical computers, the customer list would include every FAANG.

D-Wave feels a bit like a blockchain company. Is it (better|faster)? Sir, it's got them magic of (qbits|blockchain)... I don't understand your question.
I work for a car company. I think automobiles have unlocked an almost unimaginable amount of economic activity. I also think that automobiles, if they were released now, would be considered unacceptably dangerous. It's not an easy set of thoughts to square up.
Anarcho-capitalism is a similar ideology to libertarianism, only more extreme. Proponents are called Anarcho-capitalists or "ancaps" for short. The idea seems to involve being able to start a private alternative to government (with your own private police force enforcing your own laws, etc.)
Wow, is that accurate.
> The very first school on the list [2] has funding of $14k per student.

The problem is that, according to the Gates Foundation, $14K is about the minimum point at which you start to have a functional classroom (and that study was about 10 years ago, now, so the number is higher)

Not a good point. A minimal point.

And the national average is below that.

And people then wonder why our schools suck.

In the vast majority of consumer-facing sectors, non-captive markets only exist in the pages of introductory economics textbooks.

Even in B2B, most commercial transactions are with an oligopoly, or monopsony, as one party to the transaction. Competition-driven customer service doesn't exist here. For instance, not even enterprise-level customers can get meaningful customer service out of the likes of Google.
Ah yes, that's that good ol' argentine bureaucracy.
The degree to which you are taken seriously when you announce that a thing should happen because you care that “it will make the world better” is tightly related to your credibility as a person who cares about making the world better. When you announce that the only causes you support are those that directly enrich you, you’ll find that people are more skeptical of that claim. Agree or disagree, but it’s why PR has existed for decades (centuries.)
I can’t think of a much less productive use of one’s time than masturbation.
In another comment I mention one piece of research indicating that overall our non-pharmaceutical interventions didn't do much of anything other than small short term effects. There's a fair bit of data showing that while people feel good about masks and social distancing, it doesn't appear to affect the pandemic. However, more focused efforts like protecting nursing homes could've saved half the lives lost in this pandemic (https://www.washingtonpost.com/local/baltimore-nursing-home-...). But it generally takes well trained professionals to do it consistently enough, IMHO.
First thing I thought is you can in effect put the support person on hold to wait for you ;<). It's using technology to give power back to the user and I like it.
> There are better ways, but they eat at the profit margin if you were only to maximize on profit, yield, and market value. If the goal, however, is towards the well-being of the community and the land in which things are farmed, then there are many methods with which we can accomplish that while still feeding people without requiring a huge amount of labor. But it comes from a different way of seeing the world.

These goals are compatible. They require a government body, representing the well-being of the community, willing to tax externalities and use the funds to invest in revitalization.

However, expecting government to be economically responsible is about as likely as expecting profit-maximizing corporate entities to be socially responsible.
Probably the poster defines a word as a buzzword if you don’t know why the underlying concept the word represents is of importance or relevance. And there is a lot of jargon and abstraction here. Without a “basic mathematical sophistication” = Bachelors in Pure Math, it would sound like abstract babble. Even with a Basic Mathematical Sophistication (BMS, I’m claiming the acronym), it’s pretty far out there. Fair enough.
There are smoke alarms for that.

This is exactly my point. They listed the top-line, total number of all PRs without any filtering, then when they calculated the "spam ratio" they filtered out "invalid repos" as well as "spam PRs". It's a misleading statistic.

Even if that was true, it's not true of adults, including the ones that work in schools, or the ones that have children in the household.

I was doing some programming language work last year for Facebook Horizon, and while not appropriate for that product it really made me interested in building a visual Forth or APL for programming in VR, mostly because the high amount of expressiveness with minimal symbols.

We are doing computational chemistry, simulating molecular structure and designing molecules, and we want to use thousands of cores and get as much performance as possible. If my AWS bills are any measure - then yes - the cost savings in electricity and computing resources are very significant.

Also, developing and maintaining Python/C++ bindings for complex libraries is very painful and frustrating. I wrote Python bindings for years using boost::python and earlier Swig and keeping bindings working and dealing with the different memory management approaches of Python and C++... bleh - it's a nightmare. At the same time Python changed from version 2 to 3.x and libraries I depended on and my own Python code was being broken and becoming outdated in ways that I had no control over. It was like trying to build a house out of sand.

I've only been using Common Lisp for the past 6 years - after three decades of writing in other languages including Basic, Pascal, Smalltalk, C, Fortran, Python, PHP, Forth, Prolog... Common Lisp feels great, it feels powerful and every function I write I know will compile and run in 20 years. Common Lisp has real macros (programs that write programs! implemented in one language), dynamic variables, generic functions, the Common Lisp Object System, conditions and restarts... There are many features that haven't made it into other languages. Common Lisp makes programming interesting again.
When I read about this, I expected a lot of unnecessary but positive PRs, or some grammar-nazi-ness, but actually it is really pure spam:

The changes are not even positive contributions, it literally breaks the documentations and adds some useless or unwanted meaningless SPAM.

> get left alone all day

This is called "benign neglect" and for me at least, it was an _essential_ part of my upbringing. I got to pursue stuff without interference. Nobody forced me to do sports, join clubs, study anything. After I came home from school I was completely on my own and did whatever the heck I wanted, from a very early age. Want to spend an afternoon soldering something? Fine. Fixing a moped? Go right ahead. Not doing anything at all? That's fine too.

> puts kids in contact with adults who can serve as role models

Do you have kids that attend public schools? God help us all if kids treat 80% of their teachers as "role models". One in five teachers my son is in contact with even remotely passes as a role model. Older guy, leads the school band. Everyone else couldn't give less of a shit even if they tried. And why give a shit? You can't be fired for not giving it anyway.
I disagree that political vs apolitical is purely semantics. Given an initial goal, there exists a policy to accomplish it that is truly apolitical. But I do broadly agree with your points on the status quo and dispersion of effect across political groups.

> But the better question is does a socially active company have a more positive impact on the world?

Your total impact tends to be greatest when all your effort is concentrated on a small surface area. An organization that optimizes for two things almost always has less total impact than it would if it optimized for either one alone. To maximize impact, you'd be better served starting a company that's 100% focused on solving the problem you wanted to solve in the first place.

> I doubt the cost of employee annoyance and loss of focus is more than the benefit of enacting minor policy and fund diversion that could positively impact millions.

Generally if you want to impact millions in a real and lasting way, it will cost you more than some minor annoyances and fund diversions — even at a company as big and successful as Coinbase. The tradeoffs here are real, and I strongly suspect Brian is speaking empirically when he talks about destruction of value.
I "independently invented" ULIDs for a past work project.

Not a criticism, but something to be aware of, is that SQL Server doesn't sort the uniqueidentifier data type as one would expect. Instead of being ordered by bytes 0-1-2-3-4-5-6-7-8-9-10-11-12-13-14-15, uniqueidentifier values are ordered by bytes 10-11-12-13-14-15-8-9-7-6-5-4-3-2-1. So you want the timestamp in the last 48 bits instead of the first 48 bits.
When I think of top public high schools, I include magnet schools, which are also only limited by travel time, as long as you gain admission.

Homeschooling doesn’t always make kids weird — parents of weird kids often pull them out of school because of bullying or fears of bullying.
“But we obtain the puzzling result that, when rewarded, volunteers work less. These findings are in line with a large literature in social psychology emphasizing that external rewards can undermine the intrinsic motivation for an activity.”

Be very careful assuming that a payment motivates open source developers. If you offered to help me do something for an hour for whatever internal motivation you might have, and afterwards I offer you $5 for your time, you would likely be demotivated.
I saw that, but... could they have optimized their classical code? Was it just a garbage batch script running single-threaded on a single-CPU machine backed by a MySQL SELECT * FROM query? Frequently these types of sweeping statements fall down with the slightest breeze.
> Teachers are not paid based on supply and demand.

Actually, they are. There's just lots of crappy supply.

Pennsylvania got wonderfully hosed by this. Back in the late 1990s(?) Pennsylvania put up a real teacher's test. The problem was that almost half the teachers and would-be teachers failed the test. When Pennsylvania was about to have to face the reality of supply and demand (lots of money to pull in teachers who could actually pass the test), they simply scrapped the testing plan instead.

People only care about education quality until they have to pay for it.
It performs computations; it does so using quantum effects; therefore it is a quantum computer.

Every single thread that discusses D-Wave ends up with this same talking point about "universal" quantum computing. Yes, it's not yet another vaporware gate-model QC toy like Rigetti or Google have; it's a very specific sort of accelerator, somewhat akin to a GPU or a vector processor - not in terms of what it does, but in terms of requiring specific programming to make it useful. It's simply a vastly different architecture than gate-model QC: in many ways, it's a descendant of the analogue computers of the 60s and 70s.

The key differentiator here is that they've been able to scale their model from a couple hundred qubits to >5000, in production for anyone to use online. If you're a mathematician and you can actually model your problems this way, they have a nice SDK and it's very usable. There's every reason to assume that they'll have 10k qubits with even more connectivity in a few years, and they have this hybrid solver thing which takes in 10k+ variables already, so it's clear they believe in the problem model itself.

I just wish I could make it do more - my layman's interest has only taken me far enough to get a basic idea of what's going on for curiosity's sake. I think you need to be a mathematician in order to be able to do anything serious with it, right now.
I think increasing the pool and bursting the "good schools" bubble may improve the overall level of students.

We won't know until we try: individual states provide an awesome sandbox for such experiments.
And a 3br house there is probably $1.4 million.
> Mostly it's driven by the teacher's unions. If we wanted to we could find ways to open the schools. It's just the people who feel the effects of the policy making are not the ones with a voice.

No, the problem you are complaining of here is that the people that feel the effects of the policy making have too much of a voice.

I mean, unless you are have a convincing argument that teachers are somehow unaffected by policy regarding the manner in which teaching is conducted.
Such a shame they didn't include LuaJIT.
In one part of LA theirs basically a small city completely surrounded by LA called Culver City. Culver City allowed for low income housing to be built , but then didn't allow those low income families to attend Culver City schools. Pretty overt classism( along with some other isms )
Asana up 37% and Palantir up 50% as both direct listings hit the public markets
Learning 'how to think' isn't exactly a goal for 6-8-year-olds. At this age, the focus should be on integration--learning to get the mind and body (and will or spirit) working together, being in the world. 'Thinking' isn't really the focus. Ages 6-8 also involve two separate developmental periods: a six-year-old is in a much different place than an 8-year-old.

I like how Waldorf approaches this: https://en.wikipedia.org/wiki/Waldorf_education#Developmenta...

Notice that 'thinking' isn't really a focus with Waldorf until around age 14.
So, I don't know that profit, extractive-value, market-value, capitalizing are really the right frame, here. Alternative systems like the Soviet Union had similar paradigms without necessarily relying on profit. These industrial processes are necessary for addressing quality of life (including quantity of labor required, lenghth of working day required, etc) regardless of whether that system is profit-seeking or not. The Soviet Union had cars, fertilizer, pesticides, plastic, lots of oil and gas, antibiotics, vaccines, sanitation, and appliances for the same reason they're profitable in the West: it actually helps people's quality of life.

That's why the essay is framed in terms of industry, not economic systems. Because that's somewhat orthogonal. (And I do think Chesterton's Fence would be a valuable point, here, too... Money and profit are tools for understanding and facilitating the efficiency of different activities, and to me the negative conditions of capitalism are a side effect of the efficiency it facilitates. If we're going to replace profit with something else, we must address how we're going to establish similar efficiencies. IMHO, a more established path than tearing down capitalism entirely would be to keep capitalism and profit, but just redistribute and rebalance, i.e. cut off the ends of the distribution to keep things from going crazy and eating itself.)
Teachers unions on COVID have not been shy about citing their members health and safety as a central concern.

Citation desperately needed. Having grown up in the suburbs and participated in the exodus along with everyone I knew that could, detached housing is an isolating personal hell (and a pain to clean and maintain on top of it).

Places where single family homes exist rarely even have the option for high density housing and, in the US at least, never have the public infrastructure to support it.

It's a learned excess not a requirement.

Ask HN: Import Common Lisp Code into Parenscript
I have trouble understanding what parenscript does and not does.

Am I "out on Mars" in the Lisp world with parenscript or can I also make use of other Common Lisp Code easily like trivia etc? What are people actually doing with parenscript, develop everything themselves from "the ground up"?

Thanks
It makes sense, they have very little to lose other than the glarimg issue that even with a non-free license it would inevitably end up being used to run Office on Linux via syscall or full emulation.
natural gradient descent is big in reinforcement learning -- proximal policy optimization (popular RL algorithm, most famously employed for OpenAI DotA bot) can be thought of as a cheap approximation to it. people also use something called KFAC, another approximation of natural gradient.

you can understand everything in those papers without understanding differential geometry, just basic linear algebra -- the core idea is just preconditioning gradients by the inverse of the Fisher information matrix.

the deeper theoretical stuff, i have no idea about, it seems like it must be fascinating though!
Wow I absolutely love this.
I’d be interested to know what the costs were if you just got sensible tires instead of those designed for speed.

For the vast majority of people 0-60, etc aren’t the most important part of a car. Going from A->B without losing traction at normal driving speeds are what matters.
You don't even need the temporary files:

...write, write, write some more...
:w !fossil wiki commit "The Foo Article" -

Wrapping all of that up into Vim macros would be a small matter for someone sufficiently interested.

I'd never heard of trijets being dangerous before and I can't find anything to support that claim. I thought the issue with them was the expenses around building and maintaining them.
