> make things which are bland and ugly and depressing

How you feel about art is a reflection of you, not society. If you think this art is "bland and ugly and depressing" then maybe you should examine yourself as to why you feel that way. Plenty of people find concrete art interesting, attractive, and stimulating.
Agreed, and, in addition, having every single student explain their program would be a significant burden on teaching resources.
> They charge by the GB and are not exactly super cheap so if the customer wants to store a big fat file of easily compressible zeros then whatever, they got their money.

That's not a good argument: they could lower their costs with compression, still charge the same, and make more profit.
It was 8th or 9th grade for me when the switch happened. We were still doing areas and perimeters.

A calculator actually helped me understand physics a lot better, especially things like slopes.
I think these are great ideas, with not much chance of passing. Imagine all the environmentalist groups screaming that they're going to silence legitimate criticism, shut off debate, push through poorly thought-out projects, destroy our environment, etc. etc.

I said "not much chance" rather than "no chance." Eventually, some watered-down version of a law like that might pass.
I don't see how a train could be creating confusion - it's just a vehicle (apparently, what a shit implementation).

I find it hard to believe that even the smallest light rail/tram deployment won't have higher capacity than your average bus deployment (not BRT). Can you name the system so that we can check the passengers per hour capacity?

Overhead power lines means electric propulsion, so lower noise and less pollution (electric buses are a rarity and only work on short routes).

The supreme court has never ruled on this issue and Florida is not in the 9th Circuit. Circuit courts are parallel to each other in the judiciary, and are not bound by each other's precedent. As a result of this, the supreme court will usually hear cases in which different circuit courts rule in conflicting ways, to set a national standard.
The books present "Pa" as a hero, but if you look at him with a critical eye (as Fraser's book does), it's pretty clear the family's woes were largely due to him. Their original farm was by all accounts the best of the lot, and if they had stayed at the second one in Kansas they might have done OK. But he abandoned that one too based on (incorrect) rumors that the land would be confiscated, and every move they made afterwards drove them further and further into penury.
> They should have gone down the 101 corridor in the central coast area.

You can't even put a decent speed freeway, much less high speed rail, on parts of the 101 corridor.

Of all the armchair alternative route planning for HSR I've heard—and there's been a lot—this is the worst.

> The weather is pleasant and I could see people living along route and commuting to SF or LA. Central Valley was a dumb move.

People do live along the planned alignment (which is why it was chosen) and do already commute to the Bay Area as far as that is practical (and a bit more than most people would think reasonable) with existing transportation options (same on the LA end), and both displacing expected growth in freeway trips from that and extending the viable commute radius along that existing route is part of what HSR is aiming to do.
Adding a bit more explanation...

4. Therefore, the linear function giving the values of the sum simplex is constant by #2. Since any point's value is a weighted average of vertex values, and all the vertex values are the same, every point's value must also be the same.

A rigorous proof could be developed by considering the standard simplex generated by the coordinate unit vectors, but scaled by a factor of n. For example, the equilateral triangle is the 2D simplex generated by connecting the vertices at (n,0,0), (0,n,0), (0,0,n). On this simplex, the integral points (x,y,z), where the coordinates x,y,z are integers, are the points assigned numbers in the blog post. The numbers are assigned based on the first coordinate: f(x,y,z) = x, and similarly in higher dimensions. "Rotations" are done by switching x with any other coordinate axis (actually a reflection), which maps the simplex to itself and maps integral points to integral points.

That is what they found in this study, but the OP said it was likely "noise" and had no scientific basis for saying that. My point; saying something is "noise" is a way to look cool on HN and dismiss any finding that does not fit your world view.
And they could probably upgrade the system to transmit both power and a modulated signal to let the bricks communicate.
- Who pays for the low latency high capacity data storage costs?
- The ad-model subsidizes almost all costs for the end user. I couldn't even DREAM of storing an arbitrary amount of photos and videos and text spanning years, highly available all the time, ability to search and communicate with anybody etc for free without this.
There are huge costs involved with this that the "data moat" subsidizes.

Note that I'm not referring to the "morals" of doing this, my question is pragmatic.

- Why will say, a Facebook do this with "decentralized data"?
- How do they pay their bills, what monetization structure do you envision?
- Will people pay for something they have always had for free? It won't be a nominal amount since they have to bear the costs of running the service, there's no subsidization.

yeah Copilot really changes nothing here, all these basic questions can be found with a quick Google search. The reason Copilot is so good at these types of questions is lazy professors assigning the same basic stuff so there is a ton of training data.

instead of writing an article crying about it, the professor could try making some unique questions to test knowledge of the underlying concepts
It also happened under the cover of an obscure promo program that was far less visible than a rival app store. I don’t believe it is a true precedent for the hypothetical people are worrying about here.

Another important factor is the consumer backlash it’d engender.

https://news.ycombinator.com/item?id=30808926

To do something as disruptive as to create a new App Store and force everyone to migrate is not easy. Users are sick of juggling as many user accounts as they do already. Not all existing iOS users will switch, there will be grassroots viral social media campaigns on other platforms warning people not to use it, and it will bring a lot of bad PR. It would not be a frictionless transition and Meta would quickly discover that it is more trouble than it is worth. (And as I’ve pointed out elsewhere, I don’t believe Facebook or Google have the gumption these days to create widely popular new products these days.)

Ultimately, I believe both the public in the form of democratic government, and in the form of consumers, can be counted on to do the right thing. We should not put ourselves in the position of simply relying on one corporation’s benevolent paternalism to check the power of other corporations.
Part of that missing atmosphere was that in D1 (and to a lesser extent D2), you were a weak human and death was around every corner. You might walk into a room and near-instantly die. You spent a lot of time running for your life.

Contrast that to D3, where I literally beat the game the first time without using a single health potion. You were a super-hero who could punch a skeleton and send the pieces flying at level 1. And while I can certainly see the allure of such experiences (hell, I enjoy them too in other games), it was not what I wanted from a Diablo experience.
Extra nitpick regarding generated code: the `quicksort_random_pivot` implementation isn't what people commonly mean by "quicksort", as in: it's not in-place. This means that some properties like space complexity are also going to be different than what's usually expected of quicksort.
I mentionned that Diablo 3 feels different. Its art style and gameplay loop are both going in a different direction. It's quality has nothing to do with it.

I'm just surprised there isn't a standard, even POSIX utility to run shared libs but by calling specific functions. It would avoid the need for executables that just wrap a few api's in the shared lib.
Not necessarily. The skills could become irrelevant just because the models advance and you need new and different skills to query them effectively.
> The goal was to destroy Polish state.

Are you sure? From your link:

"The reason for the massacre, according to the historian Gerhard Weinberg, was that Stalin wanted to deprive a potential future Polish military of a large portion of its talent".

Also, if they wanted to destroy the Polish state, they probably would have then as Poland had no way to defend itself at the time.

> Because Russia is waging a freaking war with Ukraine right now and threatening nuclear holocaust to Poland?!

> Like WTF?!

Exactly. If you believe Russia is threatening nuclear holocaust and has an agenda to destroy all Poles for whatever reason, I can see how you would be prepared to do anything in your power to destroy them, perhaps kill off every one in their country, because that would be justified if your aprehensions are true.

That makes me scared for the future of Europe because this sort of hatred is bound to, one day, blow up again, sooner than most think (as it's doing now in Ukraine).

That’s a good point I don’t have a rebuttal to.

The potential dystopia is that crypto can lead to something like a digital society that’s completely naked to the nation state and everyone knows what everyone else has done, forever, always. Every transaction, movement and digital app usage would be in a transparent public ledger with everyone’s IDs attached to it.

It’s not a good scenario and which is why I feel like any idea that CBDCs are a good idea seem delusional.

I would ask if throwing out unfounded opinions normally works well for you in society, but I suspect it probably does. For the record, I reserve rude comments for the internet.

I don't want to have a phone call with you about your boring, detrimental attitudes towards art and other people's appreciation of it. I go out of my way to inject myself into discussions exactly like this one because, as I said, I repeatedly see engineering-brained people (who have a lot of sway) going out of their way to deride Other People's Good Time, and I want you to stop doing it.

Let people enjoy things, it doesn't hurt you. Leave them alone.
>'Women Most Affected'

This is not my position. My position is "Some Women Affected". Some covers a very large group. I'm not making any quantitative or qualitative comparison to other groups; I think it's probably impossible.

I agree.

> inherent delusion of feminism

I don't think assertions about what is or isn't inherent to feminism are possible. It's a term that identifies different sets of (often contradictory or opposite) beliefs depending on who you talk to. Most frequently, it's just moral cover for a person's own beliefs about what constitutes fairness, dignity, and respect.

I also observe that most people I meet who identify as feminist (or progressive) use the term equality to mean "fairness, dignity, and respect" which is confusing to people who engage rhetorically with them.
At that point should we count grades at all, other than a basic evaluation for the student’s personal use?
Also, there’s a deep relationship between DL and symbolic reasoning:

The tensor networks in DL end up looking really similar to tensor representations of the diagrams equivalent to a type theory — down to convolutions being a way to “type” data in an input.

We’re just now exploring that, but this may be another case of “algebra-geometry equivalence” with DL giving us a differential/geometric interpretation and symbolic reasoning giving us an algebraic interpretation.
The delta in comparison to the timescale was extremely small, though. Stagnation does not necessarily mean "nothing ever changes at all", just a very small rate of change compared to the modern era.

A life of a person in 8000 BC was not that different from life of a person in 7000 BC. For a person from 1000 AD, the world of 2000 AD would be wholly unrecognizable.

Highly organized societies tend to transform their environment very thoroughly - just look at all the Roman buildings and facilities that still dot the landscape from Spain to the Levant. A rural society wouldn't be capable of building something like that.

> Eventually the computational capacity will reach the levels that virtually any app can be replicated inside of it, with a much lower fee for the developers/owners and having full open source code.

How do you figure? Skilled developers have struggled to efficiently scale an application from one to two rack servers connected with Infiniband, never mind a hodgepodge of heterogeneous hardware and WAN interconnects running a distributed VM. There is nothing in blockchain (nor immutability generally) that actually addresses the underlying issues here, and if anything I would expect the requirement to cryptographically validate all data committed to the chain to make inefficiencies related to synchronization orders of magnitude worse, not better.

> - Slack lets people subdivide the chat space into "virtual rooms" or "channels" as a 1st-class concept.

In my opinion this is very much a double-edged sword. At my organization we have one person (maybe self-appointed) who, when seeing a question asked on a more general channel, invariably responds with something along the lines of “have you checked #super-niche-channel-probably-only-useful-in-this-exact-case?” When I see one of those questions pop up, I usually try to guess the particular sub channel that he’ll try to redirect the asker to but am rarely successful.

But my org may just be using slack wrong. We do have thousands of channels and the same order of magnitude employees. Maybe guidelines about the granularity of channels would be helpful.

Or maybe Slack is just not for me: e-mail is my preferred method for asynchronous comms and I prefer phone calls for synchronous comms because I think the slight friction in having to pick up a phone to make a call helps limit throughout and improves quality of requests. And for info repositories I prefer a curated wiki page to discussion threads for both search and comprehension.
There is zero intuition about the Laplace Transform. It just is. Like English or Chinese.

Who’s idea was it? The problem is that there’s no credit given to a product manager at Lego for original thinking and delivery. So it’s DOA.

I’ve seen this as a bit over my career doing engineering. The decision maker for product innovation is not an engineer. Not to say engineers aren’t generally innovative, but a company is not set up for an engineer to take an idea and execute it, but rather to take a vision and build it.

When engineers, hungry to build, realize this, they end up building outside company boundaries - sometimes creating new companies.

To take these bricks to market, independent distribution (and a patent) would be worthwhile. I don’t generally believe in patents for software, but for hardware, it provides a counterbalance to the aforementioned culture of modern work.

True story. I got my CS degree pre-internet. I did well with programming. Some of my friends / peers were less talented. In one of my 300 level courses the assignment was more difficult than usual. I naturally figued it out. They struggled.

Evetually I gave a copy of my code / solution to Friends Group A and also to another Group B. They didn't know each other. I said, "Be careful! If you copy, disguise it."* Deadline comes. Everyone hands in their work.

The following week, we go to lecture. Prof walks in and writes a list of names on the board. I knew each name. I knew what was happening. I waited for the shoe to drop (i.e., my name on the list). The shoe never dropped**

* In retrospect, this was a stupid on my part. If they knew how to alter enough it's likely they'd be able to write it themselves. That is, I all but suggested they walk on water.

** Also in retrospect, the TAs + prof had to realize I was the source. The class was big but not that big. And if only some completed the assignment correctly, the source had to be not difficult to identify. I'm not sure why I was never pulled aside and spoken to. Thank gawd.
