I wouldn't call that example silly IMO.

I'd consider all the varieties of B-Tree to be real example, which goes to any DBMS. You can extend this out to any direction you want like logging for concrete examples.

GIS/Mapping/computer vision has tons of algorithms and data structures that all needed to do better than linear time as well.

Stream processing in general is another, but that ends up being probabilistic more often than not, so weak punt into that direction.

If you expand the use case out to sublinear space as well, I'd argue for compression of all kinds.
Ask HN: Is futurism Banned on HN?
I recently submitted an article from futurism dot com [0]. I later noticed that HN comments weren't available for it (something I'd never seen).

I then searched here for other articles from futurism dot com (just click the domain in the post) and realized that they were nearly all marked dead.

I haven't researched the site—the article just popped up in my feed. Is it banned here? If so, why?

Ah yes, the predictable “it’s propaganda” comment every time someone writes something that could be considered negative about China.

It's quite the opposite. It's only negative stories.

Ask yourself, when was the last time you read something genuinely good written about China in the mainstream western media? It must have been a rare event.
A lot of discuss here--sorry if my thoughts are a bit jumbled, but:

> The idea that you can have an economically sound career talking about historical colonialism is a bit far-fetched

I don't believe all careers need to have economic soundness as their pursuit.

> the idea that there can be survival and satisfaction for all

I feel that it's wrong to dispossess people of their lands and resources just because you can. I think that perspective is underrepresented in our society. I think there is usefulness in teaching "the other side" of history. I also believe a wealthy society should invest in jobs that are not "economically sound".

> practical concerns are ignored and the topic is judged under a lens of morality and dogma

What do you mean "practical concerns"? What other lens is there than morality? I don't believe morality can be dogma, but interested to hear your view.

> dogmatic and removed from reality

Present reality? No room for moral correctness or the study of it?

Correct me if I'm wrong, but it seems the thread of your comment is that everyone should have an "economically sustainable job". Why is that so important?
That's insane. The people you buy drugs from are dummies.

Good to see this attitude becoming increasingly prevalent. I'm used to being a Cassandra in IT world, and while I'd have greatly preferred being wrong in my 2019 research concerns about data sovereignty, cloud-repatriation, vendor lock-in, and a shifting geopolitical landscape, welp, here we are anyway. I cut my teeth in data center operations and defense contracting, and knew immediately the real cost of public cloud would be the forfeiture of sovereignty to whichever country (and companies) controlled the major providers - surprise surprise, I was right. The solution was never to outsource core government infrastructure to a third party, but to build it in house and recruit the talent needed to keep it running, something easily done on most developed governments' budgets; by outsourcing to public cloud service providers, they traded national sovereignty for empty promises.

Bookmark this comment, because my read is that in five years' time the question won't be whether or not public cloud providers can be trusted, but how to engineer infrastructure on cloud providers you cannot trust. How do you encrypt storage on a cloud platform when you can't trust the vendor's tooling to secure your keys? How do you orchestrate K8s clusters in a provider who knowingly gives a hostile foreign government access to your etcd or network layer? How do you handle data boundaries within your own org when multiple countries with competing standards demand residency of data and infrastructure? I worry it'll be the "Chinese Firewall" problem but on a global scale, as different regions carve out their own digital kingdoms and demand fealty or expulsion.
> A type is very easy to see localized on the function.

"You Keep Using That Word, I Do Not Think It Means What You Think It Means"...

When you say "types," can you please give a concrete example of what languages you're talking about? Whenever someone talks about Clojure from type theory talking points, they make it sound like it's completely untyped or weakly typed. Clojure has its own type systems, and you can express things in them that are far more difficult to do in some other languages, even with static types. It is also a strongly typed language, and in practice, I feel far more confident about our Clojure code than anything written in TS or Java.

Sure, static type systems have their value, and some of them are really nice. In practice though, whenever I have to jump in to deal with Java, Typescript, or even Rust code - there's so much seemingly unnecessary fluff, and I don't feel the practical worth of dealing with types - it almost always feels taxing. Haskell/OCaml is a different story - I can buy that one. But realistically, getting to the point of writing practical software in Haskell is an incredibly bumpy road, and (relatively) few programmers successfully achieve good milestones on it.
Short sweet and to the point. Why isn't this a button in the bios, naturally hidden behind a few levels of menus? "Defrag your NVRAM" Other than power failures what would other failure modes be? I guess if the NVRAM has bad cells? Guess it's easier to just reset the whole BIOS whenever there's a problem?
Sure, rhetoric matters for style points, but the act supersedes stylish rhetoric. I’ll take proper action with clumsy rhetoric over inaction or improper action backed up with eloquent rhetoric, which is what most politicians provide.
> They were going down for an entire decade. You can't remove an entire decade and then say "steadily rising".

I certainly can, over a century.

> The numbers also went down 5 years in a row in the wake of the 2008 spike.

Yes, that's how long it took to reduce spending and it still didn't bottom out at pre-2008 levels. This all contributes to the trend of increasing expenditure relative to GDP.

> And if you don't treat covid as an outlier, then the numbers went down massively from 2021 to 2022! Treating 2020-2021 as normal years works against your argument more than it works against mine.

No it doesn't. It still didn't drop to pre-covid levels.
I worked for a company where they seemed more concerned with tax liability than developing products and securing customers.
I'd be tempted to write up a list like

-Fixed 20 bugs
-Understood some requirement better
-Called 5 vendors
-Kicked a few tickets back
-Measured the size of some equipment
-Utilized a new static analyzer
-Stood up a new dev board
-Kinetic model updated with some new parameters
That's sad, not ironic
The problem with examples like robbing a bank, is that there are contexts where the information is harmless. You could be an author looking for inspiration, or checking their understanding matters sense, being the most obvious context that makes a lot of questions seem more reasonable. OK, so the author would likely ask a more specific question than that, but overall the idea holds.

Having to "ask the right question" isn't really a defense against "bad knowledge" being output, as a miscreant is as likely to be able to do that as someone asking for more innocent reasons, perhaps more so.
That's a great idea, thanks! I'll do that tomorrow or so.

As a preview, two specific cases I've seen:

1) In PRs, some companies like to have semi-structured metadata, like a link to a related ticket under a heading "Ticket". In mdq, you could find that using `# Ticket | [](^https://issues.acme.com/)`

2) Many projects ask people who submit bugs to check off whether they've searched for existing bugs. `- [x] I've looked in the bug tracker for existing bugs`
Let’s face it, if you guys pick up steam, you’ll be doing your own hardware. It’ll be amazing that if that happens, you’ll also sell that hardware so that other Oxides can bloom, but you won’t and your excuse will be economic.

The problem is none of these hardware vendors have enough customers for them to be open with their specs. Even if they did, the majority of their customers would not have the expertise that you’ve hired for to competently take advantage of that interface. Instead, they’ll lob some HAL code at the customer, and if their orders are big enough, give them support. Internally, these hardware vendors will have multiple sourcetrees for each customer, and one customer’s fix will not be reflected in anothers for fear that it’ll break whatever the other customer is doing with it.

:(

That said, I hope you guys are supremely successful and spark a change in culture.
Having kids used to be a peer status signal. Maybe an expensive dog is just as good now?

People are highly motivated to chase expensive status signals (expensive can be time or other resource commitments).

I reckon the better-house-upgrade-cycle drives a lot of the economy. Perhaps less so now, when many people can't afford the down-payment/mortgage. I watch friends working really hard to over-capitalise.
Back when I was using CodeWarrior to make a game for PlayStation 2, I found a compiler bug, but fortunately, it was one where it gave an error on valid code, rather than generating bad output. I can't remember the details, but I had some sort of equation that my co-workers agreed should have compiled with no problems. I was able to rewrite it a little to get the result I wanted without triggering any compiler errors.

Civ VII I actually think has a lot of new ideas. The game has civilizations transform into other ones. Ever since Civ VI they have made it so you need to spread improvements across tiles instead of building tall.

> perpetually aggregate money to manage as a tax exempt hedge fund

Yes. That's the grand purpose. To do exactly that so they can exist in perpetuity.

Do you also go around pointing at hearts as if it's all some grand revelation that that's the main reason we're all here, making it also very clear that you don't mean it in the loving, metaphorical sense, but simply referring to its function of pumping blood about?

Sure, if you want to reduce a university down to simply existing for money's sake, then go ahead, but then you might as well say that about literally everything. Horrifyingly cynical. Is our grand purpose, in your eyes, the accumulation of money as well, simply because we want to live with a roof over our heads that costs money?
So refreshing to read.

FWIW, this is what ChatGPT says:

Me: Has Elon Musk ever used the phrase "move fast and break things"?

ChatGPT: No, “Move fast and break things” is a phrase famously associated with Mark Zuckerberg, not Elon Musk. It was Facebook’s internal motto for many years, reflecting their approach to rapid innovation and iteration, even at the cost of breaking things along the way.

Elon Musk, on the other hand, has used phrases like:

• “The best part is no part” (referring to simplifying engineering designs)

• “Failure is an option here. If things are not failing, you are not innovating enough.”

• “Move fast and fix things” (sometimes attributed to Tesla/SpaceX as a counter to Zuckerberg’s phrase)

Musk does value speed and iteration, but he tends to focus on engineering precision and iterative improvements, rather than outright breaking things recklessly.

Show HN: HelixDB, Open-Source Hybrid Graph-Vector Database
Hey HN!

A friend and I have been working on HelixDB, a graph-vector database, part-time at university.

We're super excited to release the first version of our Graph Database!
Helix is being built to incorporate both graph and vector types for building RAG and other AI applications.

This release introduces our graph DB, our new query language, HelixQL, and our CLI tool to help run Helix.

You can install helix locally by running `curl -sSL https://install.helix-db.com | bash`

We'd love you guys to play around with it and hear what you think.

An optimizer produces a single optimized set of parameters. AI is a (usually parametrized) function mapping a collection of input states to a collection of output states. The function is the AI, not the optimizer. I'd suggest anyone who thinks otherwise go and do some basic reading.

Compilers are multimillion line programs, and they have an error rate which is commensurate with multimillion line programs.

That said, I think like half the bugs I see get filed against the compiler aren't actually compiler bugs but errors in user code--and this is already using the filter of "took the trouble to file a compiler bug." So it's a pretty good rule of thumb that it's not a compiler bug, unless you understand the compiler rules well enough to articulate why it can't be user error.
I've referenced this paper many times here; it's easily in my top 10 of papers I've ever read. It's one of those ones that, if you go into it blind, you have several "Oh no f'king way" moments.

The interesting thing to me now is... that research is very much a product of the right time. The specific Xilinx FPGA he was using was incredibly simple by today's standards and this is actually what allowed it to work so well. It was 5v, and from what I remember, the binary bitstream to program it was either completely documented, or he was able to easily generate the bitstreams by studying the output of the Xilinx router- in that era Xilinx had a manual PnR tool where you could physically draw how the blocks connected by hand if you wanted. All the blocks were the same and laid out physically how you'd expect. And the important part is that you couldn't brick the chip with an invalid binary bitstream programming. So if a generation made something wonky, it still configured the chip and ran it, no harm.

Most all, if not all modern FPGAs just cannot be programmed like this anymore. Just randomly mutating a bitstream would, at best, make an invalid binary that the chip just won't burn. Or, at worst, brick it.
