The US education system varies tremendously. I don't think you can credibly claim that this teaching method is "standard" in the US. At least my experience was much better than you described. Indeed it wasn't until university-level mathematics that I started to get into the "stop trying to understand how they work and just memorize these formulae". Fortunately my engineering classes provided a through-line for understanding how those formulae worked, and I was much stronger for it than my math-major contemporaries.
There was this wonderful podcast featuring Eich a few days ago:

"Whatabout Kaepernick" is not a denial that the left is doing this, or even that they're not the primary offenders.
Free speech and democratic equality go together. Censorship means that there is a select group of powerful people that get to decide what ideas are allowed.
Ah, I completely agree with what you have written here. My earlier post applied to using the if clause for matching to the variable value instead of capturing the value from the object.

I view pattern matching from a bit different angle - instead of viewing the case expression as answering "does the object match the pattern", I view it instead "can the object be deconstructed to a thing looking like the pattern".
That is, if you write the exactly same expression after matching on the right side, it should evaluate to the original object being matched. And I believe this holds in Python just as in other languages with pattern matching.

However, Python way of making it work is indeed a bit strange - because pattern matching is allowed to mutate variables from the outer scopes, while in some other languages I'm used to, capturing symbols just shadow the symbols in the outer scope, without changing them. This is a bit scary part of Python implementation.
You're thinking of this as some sort of ethical issue. It's just business.

What happens to businesses with fixed or declining demand? Consolidation.

The bigger players start scooping up the weaker ones. Bigger players have more regulatory muscle. There are a thousand examples... aircraft is probably a decent one. You used to have Lockheed, Boeing, McDonnell, Douglas, etc... Now you have Boeing as "Team USA", who has the political and market power to do things like ship airliners that crash for avoidable reasons.

I strongly believe that helping younger students gain strong intuition for these operators pays dividends towards their later success in maths.

I've always run into the following problem: I try to motivate multiplication as repeated addition, which does help with intuition, but then things totally fall apart when we move on from integers into fractional values.

1/2 * 1/2 -> 1/4.

Sure you can teach someone to simply multiple the numerator and denominator, but it doesn't necessarily help them make clear sense of what's going on.
Hi,

While I’ve seen that was the goal of the meat substitute co’s - I’m now seeing the fast food co’s goals aligning, which makes the plant meat business much less niche/quixotic.
Pffh, that's for lowly applied mathematicians. This is theory! /s
I have a controversial view.. (more than) enough mining will still happen even if there were no block reward AND no fees.

Why would somebody mine Bitcoin in that scenario? Because they hold Bitcoin.

I imagine the average investor would be willing to spend around 2% of their holdings a year to “protect” their investment, I.e. make sure the network is functional and immune to attack.

Which comes out to about the total amount spent now on mining (1.8% annual block reward =~ 1.8% spent on mining).
Disclaimer: I work for a competitor.

Multi-party computation (MPC) enables you to participate in public key cryptography with shares ("parts") of a private key divided between multiple participants from the get-go, i.e. without ever having the private key in memory at any point in time.

So for example, if you divide the shares between mobile devices and servers then all of them would need to communicate with one another to sign a message without any of them knowing the private key. There are variants (e.g. 2 out of N, etc.), but that's the gist of it.

Connecting it to cryptocurrency wallets, you can then use this scheme to create accounts where the control is shared between multiple devices and "mathematically" it doesn't matter then if one of the devices is compromised - it could never do anything on its own.
The problem with these busses is that each hand rolls its own security primitives and policies.

This sort of thing is better handled by the kernel, with filesystem device file permissions. As a bonus, you save context switching into the bus userspace process on the fast path. So, “the unix way” is simpler, faster and more secure.
Excited that Brave is playing a pioneering role here with leveraging cryptocurrencies and distributed tech (including Web3) who's time, it looks like, will come. It helps that a Browser is close to a perfect environment from which to challenge the incumbents heavily dependent on ad revenues.

> Brave Search's index there will be informed the activities of participating Brave users, in terms of the URLs they search for or click on, and adjacent web resources that don't require extensive crawling.

This is quite similar to Amazon's now-defunct A9.com which, iirc, had some form of hybrid search engine that was built on search / ad results from Google and the data Amazon collected via the Alexa toolbar.

> The Brave Search team has written a paper explaining its use of the term, titled "GOGGLES: Democracy dies in darkness, and so does the Web." The browser upstart aims to replace the tyranny of Google's inscrutable, authoritative index with a multiverse of indices defined by anyone with the inclination to do so.

Again, very similar to WAIS. Has Eich been speaking to Brewster Kahle? :)

The first-person view seems like it would be a total blast to try out-- basically every kid's dream toy. I would have given anything for something like that when I was 12 years old. But from a pragmatic standpoint of using the drone to capture video footage, I feel like having robust "self driving" capabilities (in particular, obstacle avoidance and smart target tracking) is more interesting. I was blown away recently watching footage of this new drone from a US based drone company, Skydio:

I also like that there finally seems to be a decent alternative to DJI in the market-- it was a bit worrisome how much better DJI has been than everyone else.
That's the point, in mathematics you can model the same object in many different ways save for trivial transformations.
Why Monstera toxic to cats?
The Swiss cheese plant or the monstera plant contains insoluble calcium oxalate crystals that penetrate the tissues of the cat’s mouth and cause high discomfort. Most cats will only take a bite of the plant and then will lose interest due to its bad taste. Although it takes only one bite, just one bite is enough to cause this condition.

I think this is one of the big things fuel cell proponents are missing: the heat and water that come out the other end are liabilities in most transportation contexts, but can be side benefits in a different setting.
The referenced argument rests on superluminal communication, not elegance. The quaternions are not even sufficient, unless we believe that superluminal signaling is physical.
Yes, and just to expand on what I meant with "thinking about the wrong things", they've got everyone thinking about killer robots and automated weapons systems and surveillance (by government entities). When in reality Google's AI is, and has long been, vastly deployed to understand human behavior for the express purpose of maximizing advertising revenue and modification of behavior through pervasive messaging, recommendations, addictive dark patterns, etc. They've basically built a completely automated real distortion system designed to trap people into spending their time staring at whatever the highest (fully automated) bidder thinks they should see. It's dystopian and all the local incentives are wrong now. They've got a crapton of money, computational power, and self-justification. The reality distortion field is powerful. We should be very wary.
This is my take on it, but I realize now that it’s going to vary a lot from person to person.

The workflow is all the jank that comes with HMR, or worse, reloading entire pages to see changes.

The port number isn’t a specific thing so much as an allusion to the workflow most people use. You’re focused on a single component quite often, but working with it in an entire page served through your entire app server. It’s overkill and slower than necessary, and sometimes comes with all kinds of state frustrations outside of the scope of your component.

Changing the port doesn’t inherently change the workflow, it’s just calling out which port most of us use for that workflow and suggesting to investigate what could be better than that workflow.

They’ve made some changes to the page now, so hopefully this isn’t a source of confusion anymore.
Show HN: Topmarq – Online Peer to Peer Vehicle Marketplace
Hey HN,

I’ve been flip flopping on whether to post this here as I know there have been some arguments about whether HN is too broad an audience, but ultimately decided it would be interesting to see what comes of it from the tech focused side.

I wanted to get some thoughts on my new (first for me) online marketplace. Topmarq (https://www.topmarq.com) is a peer-to-peer luxury vehicle marketplace striving to make the buying/selling process hassle free for even the most vehicle-ignorant users. We work with sellers to get pictures, videos and a mechanic inspection, and then present it online in a way that gives buyers full transparency. We shift the model from the current listings which are really just teasers to get you to see in person, to listings that provide every little detail of the car you would be buying. You can see some of our early listings up here (https://www.topmarq.com/listings/).

The entire transaction can then occur online via escrow which keeps both parties protected. By building a marketplace that buyers can trust, we aim to remove the dealer from the equation and give those savings back to the buyers and sellers.

We take a set fee from the transaction but are upfront about it. I think the trend on pricing is to move away from confusing fees and extras and just charge what your service costs and be done with it.

At this point I’d expect most people who watch TV to have at least heard of Carvana or Vroom and how they sell vehicles purely online. While it may seem that this is becoming the norm, there’s still only a very small percentage of cars (<10%) sold online in the US each year.

With the pandemic shutting everything down you would think that the number would skyrocket yet it hasn't. One of the main drivers are the dealers as their sales reps want people in the building to upsell (that’s how they make money).

Btw also looking for some additional tech talent should anyone else be a SWE with a passion for cars.
Out of curiosity, why 1/5 2/6 3/7 4/8 and not something like 1/8 2/7 3/6 4/5 where you just flip the entire stack over at the midpoint and read from the end of the stack back to the front? That would have the advantage of working even while stapled, and requiring less flipping overall.

Remember that there are people behind these decisions and they are largely rational actors. Someone at PayPal is getting a big promotion and bonus from pushing this deal. If crypto goes nowhere and they shut down this project, then it can be rationalized as "getting in too early" or some other "unforeseen externality" that happened, totally out of their control. But the promotion and risk taking executive will have solidified his/her position with headcount and other markers of success.

There are always things we don't know going on behind the scenes for these types of moves.

Remember when Marissa Mayer was poached from Google to run Yahoo, and the first big move she made in a series of bungles included buying Tumblr for $1.1bn. Then she termination the option for employees to wfh. Then was later revealed that she had consecutive bad performance reviews at Google and was not going to get further promotions there before she jumped ship.

Edit: I'm just bringing up Marissa Mayer as an example and maybe misremembering the specifics since this was 8 years ago at this point. There are plenty of other examples of executives doing weird stuff that seem nonsensical from the outside. Jamie Dimond proclaiming bitcoin is a fraud while consecutively JPM buys a hefty investment in bitcoin. Or Bill Ackmann crying on CNBC while financially positioned for the exact opposite.

SpaceX Starship SN10 flight and landing test
Yeah, the firing of Timnit Gebru strongly reminded me of the Michael Lynn saga: https://www.schneier.com/blog/archives/2005/07/cisco_harasse...

I think the analogy breaks down a little since hackers were generally outsiders to the companies (even Michael Lynn), and hiring them and starting programs around them was the thing Microsoft did to fix their relationship to the community, whereas the folks here were already insiders at Google, but maybe that was the problem, that they were explicitly hired as academics with the expectation that they would keep doing the same work, rather than internally focussed researchers working on improving the products and systems being created.
>Government regulation is needed.

Hopefully not the kind of regulation that puts a breaking burden on companies like Brave, while letting big tech do whatever they want after a token fine.

Bing search API terms of use do not allow caching [0].

"You must use results you obtain through the Services only in Internet Search Experiences (as defined in the use and display requirements) and must not cache or copy results. "

But they may have a special agreement in place due to the number of searches happening on DDG (100 million + daily [1]). They're larger than Bing in many countries.

Boundary will indeed give you a bearer token after authentication to present to take further actions in its API. So you'd authenticate to Boundary, get a bearer token, and use that to make one or more requests to connect to infrastructure or services. That bit is pretty much in line with most clouds, platforms, services, etc.

However, once authorized, the actual session uses a TLS stack generated for that individual session to establish a secure tunnel. It's explained at https://www.boundaryproject.io/docs/concepts/security/connec... if you're interested.

As for complexity, while Boundary overall is by no means a couple hundred lines, I will simply say that the vast majority of code (nearly the entire API) is related to user and resource management...how users are defined and authenticated, how infrastructure and services are described for access, RBAC, etc. The actual networking code performing the secure proxying is quite minimal because at least for the TCP tunnel it's more or less specifying the acceptable TLS parameters for that session and from there you're mostly in `io.Copy` land... it probably works out to a couple hundred lines :-D

What you're doing in Fly looks super cool and the stuff you're doing on gVisor (including the user-mode Wireguard stuff) is super cool too! Thanks for writing it up. And it sounds like the two solutions are more complementary than competing, so maybe at some point in the future you'll find that Boundary has a niche to fill in your setup as well!

Except this isn't a pedantic falsehood. Multiplication has nothing to do with addition and at some point we have to stop teaching students that it's related. Understanding ratio is key to understanding a lot of the physical sciences and you can build a really good intuitive understanding of a lot of simple physical concepts if you can just do dimensional analysis. But if you think of multiplication and division as a kind of addition then it all breaks down and you can't reason about much at all with those tools. In fact you can't even get over the hurdle of doing dimensional analysis in chemistry or physics in the first place. It doesn't make any sense. And you'll have been set up to fail by your teachers.

They're not saying "we should be teaching kindergarteners using Euclid" they're suggesting that focusing on the process of doing multiplication hides a lot of very useful insights about why someone would do multiplication in the first place.

The biggest problem with math as it was taught to me in grade school is that it was focused on rote memorization of a procedure. Which is fine if you need to calculate how long to cut 2x4s or stair stringers but it doesn't help you at all if you need to understand why that works the way it does. And god help you if nobody ever shows you the exact method of calculation for those two things in the first place. You're set up to fail if you only focus on process.

> "Yeast cannot produce B12, which is naturally produced only by some bacteria.[8] Some brands of nutritional yeast, though not all, are fortified with vitamin B12. When it is fortified, the vitamin B12 (commonly cyanocobalamin) is produced separately and then added to the yeast."

Furthermore, fortified all purpose flour is not the same as fortified nutritional yeast. In fact, what you are referring to is likely _enriched_ all purpose flour. This has vitamin B1, B2, B3, B9 and iron added to it. There is no addition of vitamin B12.

Bitcoin's value is not based on its technical ability or its usefulness. No one understands or care about PoW vs PoS. Its only practical worth is its name recognition driving more people to buy it as an investment. Bitcoin beat Ethereum and Bitcoin Cash and Ripple and Monero and every other coin because it was first, and people know the name "Bitcoin", and they've never heard of any altcoin.

No, I think there's a difference between undocumented bugs and professional documentation that very clearly documents behaviour that doesn't actually match what the system does.

As others have said, it's a problem that's particularly apparent with Microsoft - it feels disjointed. Like the documentation team read a different spec than the development team.
