Imagine: you need a data structure which allows you to store vectors in memory and then say "here is a vector A, give me the 10 vectors which are closest to the same direction of this vector A, in n dimensional space".

One can imagine there is some optimal way to lay out the data in memory such that it would be relatively quick to do that. One can imagine a naive way to do it which probably wouldn't be fast. A vector DB does the first thing - lays out the data in a way which then enables it to do that fast.

And then it does all the other stuff a DB does - persisting to disk (which means data needs to be laid out in a sensible way on disk too), handling multiple queries, updates, and the 50 other complicated things databases tend to do. Users generally want to do other operations on vector as well so a vector DB does those too.

For a small number of vectors you can build a vector DB yourself. Write a list of vectors to a file, load them into memory in no particular order, then for your "n closest" function, just iterate through the list calculating the difference in direction one by one and keeping the top n. Your simple system will work just fine for a toy demo.
Not to mention risks!
I can see his point. I'm also perfectly fine with programming without a linter/formatter for personal projects or bigger projects where quality is more important than speed. The code doesn't look worse. In fact it might end up better.

But for corporate teams, doing web dev? It is definitely necessary, unless you want to spend days reviewing trivialities, or you're ok with the code looking like a patchwork quilt of styles.
My partner experienced the burps thing, but not so much me - I get a little bloating and weird poops.

I definitely agree it makes you regret over eating, but I also find it makes you not want to eat. Just enough of an edge to make weight loss a breeze

Who cares, you're dead.
Yes, that's one of our motivations to build this std!

The feature of generating go packages from C in `ffigen` still needs significant work to be done (mostly dealing with C calling conventions on different platforms), and the generated go package only works with dynamic libraries (as it uses the pragma `go:cgo_import_dynamic`).
Yes ;) Average Lichtensteiner is way better off than average American. Lichtenstein is a very bad target for similar comparison, exactly because they are what they are.

Your Carsurance source cites the National Law Review, which cites the Carsurance source for that statistic [1]. It’s important to consider from when they polled data and how they’re segregating by manufacturer.

EDIT: Found the study [2]. It’s for 2012 to 2015. Given these are decade-old data, I’m actually surprised the gap is only 2x while fatality and injury rates were already lower.

"Best" is a subjective term, especially when talking about a performance car.

However Mazda has started releasing PHEV designs as you design over the past few years, with the RX-9 being a performance optimized variant.

If you don’t do that, you get domestic passports and gesundheitpass schemes for restricting basic freedom of movement and association. You can’t advocate 15min cities and be ignorant of privacy or treat it as an externality without colluding with some very evil interests who are co-opting and fooling naive environmentalists. It’s banality of evil level stuff.
Its not necessarily good that they just losses happen and close up store.

I guess it gives room for small business owners, who are willing to shield themselves behind bullet barriers, willing to defend their own property with guns, and don't care whatsoever about bad PR.

You should avoid plastics in general if you (rightfully) worry about forever chemicals.
I believe the argument goes that you are getting molded into a dysfunctional / unnatural state under the label of sexual liberation which then makes you easier to control and influence. The former enabling the later. I could be off though, sorry if this turns out to be a derogatory summary / simplification, its not intended this way.

I am getting lost earlier so you or the parent might be able to help.

>Which should perhaps tell us something, especially given the disastrous sexual libertinism that characterized the early communist regime of the USSR.

How does that tell us the behavior by those three actors is motivated by him trying to subvert society through weaponized sexuality(to assume for arguments sake)?

Leaving out the US during McCarthy for a moment to reduce the risk of derailing, totalitarian / authoritarian regimes acting against people criticizing them (here in form of his "Mass Psychology of Fascism" in which he also criticized the communist party and later added his orgon stuff) doesnt tell me much about the author other that he isnt a good fit for such systems. Enforcing conformity is what they are all about and at the core of the dysfunctional error correction mechanism that plagues these systems.

And more confusing, how can the second part of that sentence work as a qualifier? Does that mean you would not expect him to get this treatment in the USSR since he showed ideological loyalty on this topic (again for arguments sake)? I would argue looking at the political purges at the time where even complete ideological loyalty and conformity didnt protect you from power considerations its not surprising either.

As some general feedback regarding the rest of the post, reconsidering the certainty about individual statements as well as conclusions might make the post more readable. It otherwise reads as constructing arguments for an already taken conclusion.
Agreed. Though I'm personally more in favour of adding the cost at the other end. I think companies should be taxed for the cost of restoring the damage their products cause to the environment, as this would encourage competition towards more sustainable practices
> It feels like it's implying that humans today are fundamentally different from humans in the past. In fact it feels dangerous to me that we often speak of ourselves as almost a different species from humans in history. From an evolutionary perspective humans from any moment in recorded history are basically indistinguishable. Our brain capacity hasn't changed. We're not kinder. We're not less selfish.

When people say this (myself included), I think it's a normative statement, not a positive one. Of course we're the same humans we have been for thousands of years. But the act of calling out our failings as a society can itself, sometimes, spur people to try to change it for the better.

In 2023, we are (positively) essentially the same as our ancestors. But also in 2023, we should (normatively) strive to be better than them, and to be conscious of our failings when we don't.
I'd rather these awesome engineering feats over webapps literally any second of the age of the universe.
Are you actually involved with real estate investing?

I'm asking because it really doesn't seem like you have much experience with it based on your comments.

Housing prices go through bubble-burst cycles regularly.

National trends are interesting, vaguely, but local markets are everything, and fluctuate wildly based on many factors.

We get into serious trouble when we have external forces skew the market, like in 2008.

Covid years + essentially free loans (nearly zero interest) are another example.

It caused a bubble that's going to cause a lot of pain as the market corrects.

I'll be part of the solution - I'll buy properties (most likely next year) that are in distress, rehab them, and then sell them later.

According to you, though, that's somehow wrong. I should just let foreclosures happen, let houses rot empty - because profit is wrong?
Plus if you have any issues, you’re already on the Stripe technical support page.
He's describing a particular kind of hybrid, where the ICE acts purely as a power generator. Most hybrids don't work this way. They tie the output shaft of the ICE into the powertrain directly, so it can operate the wheels by itself if needed.

This setup allows them to make the electric motors much smaller and let the triple-rotor engine lay down power for acceleration, while the small motors handle the cruising.

The MX-30 R-EV operates the way you describe (https://www.caranddriver.com/news/a42485033/mazda-mx-30-r-ev...)
The separation often makes sense with long lived data.

A lot of data is fleeting. For example when you construct a struct out of sub-pieces. Many of those probably just live on the stack or are otherwise temporary. This type of data is passed around, read, written to etc. until it has the right shape. It goes through a little pipeline and then often becomes part of a bigger, longer lived structure or at least has some impact on one.

Long lived data is different. It's often global or is at least seen by entire modules and so on. There it makes sense to think of commands and queries. A database is a typical example.

The core idea is to make mutations obvious.

This pattern emerges in different programming domains and has an influence on a lot of programming decisions: UIs, DBs, video games, paradigms, cloud architecture, managed caching, HTTP (safe vs unsafe methods) etc. under different names, so there's an universality to it.

But... I think if we learned anything from the paradigm craze(s) is that any pattern is useful until it isn't.

I wonder if they could use multiple rotors in series, like a gas turbine engine does with stages of compression/expansion, to improve efficiency.

A "compression" rotor, a "combustion" rotor and an "expansion rotor" perhaps? That would give more chance to extract useful work and a lower exhaust temperature.

Still have a lot of thermal losses though (lots of surface area in all those combustion chambers, and a long residence time of the hot gases allowing heat transfer to happen... not ideal)
Urgent Care is probably your best option. I think the name implies a bit more than what it actually is; it's basically a corporatized group practice for general/family docs who don't want the hassle of running their own thing. At least that's been my experience, and I've talked to some quite helpful docs in them.

And for my soap box to anyone reading this - remember it when someone tells you that free/public healthcare creates long waiting times. It may, but we don't seem to be doing great here either.

> the money is in an escrow and released as the construction progresses.

too.

The problem is it doesn't work: the fund release schedule can't be perfectly aligned with each stage of the constitution on a cost basis. There's a large amount of unfinished buildings (rather than not started at all) at a certain stage - it's the point when the_amount_of_fund_released - the_construction_cost_so_far is maxed.

I like the USA solution more - no mortgage for unfinished buildings. Developers can still sell it, but good luck.
Why is it “enshittification” to stop users from stealing your product?
It could be a MITM device between the flow sensor and the controller. It could adjust the flow reading to read much less than what is actually coming out or possibly zero. The controller doesn't have any way to verify the number and it's expected that the flow can change based on the condition of the pump and filters so a very slow reading isn't unreasonable. Add Bluetooth to the device and you can turn the hack on or off at will so it will go unnoticed. Clearly this guy took so much gas that someone did notice. Steal a candy bar from a 7/11 every week and no one will notice, steal the entire candy aisle once and they definitely will.
Just here to tell you - well done! I ve downloaded the app and it is user friendly and works smoothly. Especially if you know, that this is one man army job!

Over 10 years professional experience, primarily in backend roles but am well-rounded.
Enjoy wearing different hats. Practice agile/XP but guiding principle is being pragmatic.
Have worked in various industries and teams, including highly effective product focused and data-driven teams.
Good at seeing things from different perspectives and knowing when to challenge and when to disagree and commit.
Have held director positions in small companies, and consulting positions in medium companies.
Can zoom in and out for small/big picture views, know how to lead and work with stakeholders.
Mission-driven and proactive in my work, with an emphasis on clear communication and accountability.
Preference for part-time or reduced work week (with relevant pay cut) as I'm a new dad.
Less than 100hp from the electric motors? That might not be bad, but maybe that shouldn't have been the headline figure. More interesting would be the torque data.

I'm guessing that is fairly good, as it would solve the rotary's problems with lacking low end torque.

I still think they'd have been better off with a 100% BEV, though. I doubt this will do particularly well in the market.
"Any sufficiently advanced technology is indistinguishable from magic" - Arthur C. Clark.

The reason i'm convinced this can happen is because I think the [very fundamental - read early] building blocks seem to be already there. Will it happen? Depends if a well-enough funded group with the right talent and motivation choose to aim their sights at the consumer market rather than enterprise/studios. Meaning, it will probably not be Adobe, or any of the Streamers. Maybe could be Meta or Snap.
sudo /usr/sbin/$SSH_ORIGINAL_COMMAND

By the way: SSH_ORIGINAL_COMMAND is a command like you would give to sh -c, basically a tiny snippet of sh code. Its not an argument vector! You either need a shell to kind of eval it or parse it with wordexp(3) before you can reliably tell which executable name it refers to.

Mean people might send one starting with '$(' or another expansion. Remember this is valid:

I try not to link youtubers, but I'll make an exception for F9's Wankel video.

https://youtu.be/-3HBAvkc4a0?si=9NJd4B-VK1LxfXWy

Although he's basically a motorcycle blogger, the production values manage to pump a lot of great physics[1] / MechEng information into the entertainment. There's not many mediocre videos on his channel, but this is one of the better ones.

The gist of this video: the Wankel does have some[0] fundamental problems as a concept. There's workarounds (none of which I could find in the OP, although using a Wankel as an ePMU is probably ideal) but also a point of diminishing returns apart from specialized platforms like UAS.

Rotational, high-flow, high-rpm . . turns out you're already halfway to a gas turbine anyway.

It suggests the new plastics have the PFAS. Any that are fluorinated by Inhance. To your point, the recycled may have them too, as a consequence.
Interesting, it's been like a decade since I last used windows, but I had to go and check what layouts are available, since I remember having these combinations on my layout. Apparently those combinations are provided by windows in the "Finnish and Sami" layout, which provides a number of extra letters (not just ones used by the Sami languages) through AltGr+letter combinations. I must have selected that as my layout at some point while I was still using windows, possibly for the purpose of getting easier access to letters like ÆØÕ, and just forgotten it after some time.
I'm saying "man/male" is a gender, not a sex trait.

I think they are actually talking about a series hybrid (https://en.wikipedia.org/wiki/Hybrid_vehicle_drivetrain#Seri...), which is different than a plug-in hybrid (though it would be somewhat crazy to make a series hybrid that was not also a plug-in hybrid).

.. as to why those never caught on: I have no idea. Plug-in series hybrids seem like a brilliant solution to most issues with both ICE cars/parallel hybrids and electric cars. My honest theory is that Tesla started pushing all-electric cars much earlier than anyone else would have, and that caused most people to skip plug-in series hybrids.
Society actually works a lot better if every possible way to steal from your neighbor isn't considered fair game.
that's also would allow broader adoption in countries where charging infrastructure is not yet ready.
eg. in my country we have very little charging stations because there is just not enough demand, and we do not have much electric cars because not many people want to pay that much for car that you have no way to charge (especially when you do not have garage)
I like this idea, especially the flex fuel aspect. Something purpose designed to easily convert to run gasoline, natural gas, pure ethanol, you name it. Though it might have to have some sort of cycle to ensure you don't have 2 year old gas in your tank when you finally need to charge the batteries on the road.

Superimposing light waves at various frequencies—-similar to how some sound canceling headphones work with sound waves, where sounds cancel if of different phases—where the top of one wave starts at the same time the bottom of the second wave does. It does this by creating overtones when the light hits a gas. It’s not just turning on light and turning it off again like a switch. Maybe try superimposing your API calls.

My initial thought when opening your website was that this was a job queue, like BullMQ. Not a "link things together like IFTT/Zapier/N8N but in code" platform. I don't think I'd use "Background Jobs framework" to describe what you're building, as that term has very different associations. Am I right in saying this is like BullMQ, except with integrations? If so, I'd focus more on the integration part of your marketing.
Show HN: Resonant – discover and search high quality blogs
Hey! Me and my friend made a feed + search engine for high quality blogs.

We wanted to make it easy to discover new blogs / articles based on what you have liked before. To do this, we recursively crawl blogs and their outbound links. We use sentence-transformers to embed each page, which lets us show you other articles you might like.

The final goal is to make Resonant into a social platform where you and your friends can share, discuss, and discover new high quality articles.
