Samsung TV's are known to do this kind of thing when they are within ear shot of people talking. If your phone has been set to allow access to its microphone for all the apps (or some other combination of unexpected apps), just as Android will activate the "location" permission from time to time on an update, then this kind of thing would not be surprising. Check your permissions.

My love is overflowing when I see open hardware! Your project is awesome!
Although I'm kind of worried about expensive solutions used in this project like curvy-shaped PCBs, and mad DPI sensors probably use amount of energy that is a bit higher than average which is a concern for laptop users. But this is a high-end product anyway. )

Also, seeing many HID enthusiasts in this thread, I'd really want to ask a question. Please forgive my selfishness )
All of my computer life I've been searching for ergonomic mouse that would have buttons clickable not by pressing down, but by pulling them towards the hand, like a trigger on a gun. By grabbing. I had a balled COM-port mouse once, shaped like a half sphere with 2 buttons and it was OUTSTANDING! It was ridiculously simple. Maybe it'll be reproducible with a 3D printer... Anyway, have anyone seen anything like this on the market? A wired grab-clickable mouse?
The headline is obvious (have you tried sleeping?), but the article is about a specific mechanism for vision, not the general idea.

I think if the IP is detected as used by one person the recommendation engines relies on it more heavily. For example in an office the same IP is used by many so its weight in the recommendation engine is relatively low. Additionally more and more ISPs are using longer lasting DHCP leases. I know my Comcast IP hasn't changed for over a year. This can better tie a person to the same IP.

Interesting speculation, and at least the author nods toward the very real problems:

"In addition, it’s worth noting that wallets are not very user friendly for non-technical folks. The potential to lose your ID—really and truly lose with no possible recovery, ever—exists. So, the emergence of the new kind of user described above is far from a foregone conclusion."
Ye gods an electrified bike with a 50-75 mile range, assist/etc would make this so much more accessible for people: you can tow more, get up hills, fight headwinds like a pro cyclist would. And you can recharge over lunch.

You could probably go 100 miles a day with the energy of a 20-30 mile ride, and hold 20mph if you needed to regardless of conditions. And carry all the serious rain gear too.

And the bikes are tougher, you can carry spares and tools...

The only issue is the asshole drivers of America, especially the roll coal pickup trucks. And it is tough, because rural America is conservative and full of very angry pickup truck drivers.
That was definitely a typo. Thanks for your response!
Thanks.... though note that Cf also includes things like the bidi directional-override code points, which you might still prefer to exclude.

My explanation would be fairly trivial: those videos were currently being pushed more broadly by the YT algorithm (propably based on some rough demographics that you two share - age, gender, location, broad interests...). You two probably saw a lot more of the same videos that you didn't talk about.

PS: my understanding is that a lot of social media sites use a strategy where they somewhat randomly push single posts by reliable creators, to make sure that those stay hooked as well. So that could be an explanation why you'd suddenly see something a bit more niche.
It would be fun, and possibly quite useful, to run Flex on the Raspberry Pi.
Then it's news. So what?
I have made very different experiences. The programmers don't care either. They just want to pump out features, no maintenance, no documentation, no long-term improvements.
This happened to me in 2018. We were chatting with an acquaintance about horse racing. I never showed an interest in that topic or visited the location. Just after 5 mins he left I received an ad from Instagram on Horse Racing competition which was happening in the same city.

My only assumption was Instagram/Facebook was somehow listening our conversation.
I’m sorry your wife quit and I hope she finds a job she likes.

I know many teachers nowadays too. They are friends and neighbors.

In my county, teachers get 10 weeks off and they go back a week early to prepare for school. They also have a few days at the end of the year to wrap up. So it’s actually only 8-9 weeks off where they don’t have to think about school. Of course many do. Just like I think about work on my vacation.

Pay in my state is $53k/year, slightly over the average salary of $51k. So teachers aren’t paid “so little” in my state. It’s not an amazing salary, but it’s ok.

It doesn’t take a “special kind of person” any more than countless other jobs. People fit into jobs and don’t fit into jobs.

I don’t doubt that teachers are stressed out, but I don’t know how much more stressed than other professions. Most jobs are stressful. At least teachers don’t have to worry about layoffs and they have a pension and they have summers off. So there’s pros and cons.
since it doesn't require a lot of money you simply quit your job if you want to do that for an extend period or take unpaid leave if you can arrange something w/ your employeer.
To say nothing about the differential between someone in their first year and their 30th year of teaching. (At least, I hope there's a differential! I haven't looked.)
In fictional universe of FF VI, there are magical creatures with magical abilities called espers.

What is interesting in this game, is that the evil faction in the game are not the espers, but humans that figured out how to enslave them, extract their life essence and turn it into power.

The empire does not care about the well-being of espers or their personality, they only care about their abilities.

There is a part of the game where you see all the espers in a scientific facility, being drained of their abilities and life, and then thrown into a dumpster when they have no magical power left.

That is the software industry.

The good faction are humans that decide to fight the empire, and discover that espers can voluntarily give their power to humans in a more effective way than what the empire can forcefully extract from espers. They use that power to defeat the empire.

Those guys are open source projects.

Show HN: Effortless Authentication for Your Web Application
Hey folks, Michael here.

I have been working in this project on and of for about a year and a half and I finally got it into a state where I can share it. I initially started this project to learn Rust and afterwards decided to make it useful for others.

Vulpo Auth is an authentication server that you can host yourself. The goal was to make it as easy as possible for you to get started and have a complete authentication solution without you having to configure anything. Project Website: https://auth.vulpo.dev

The Project contains:
- Auth Server (Rust)
- Admin Dashboard
- JS and react SDK
- Prebuilt Web UI (currently react) (https://auth.vulpo.dev/ui)
- rust SDK for rocket

Some of the features:
- Email and Password Auth
- Passwordless Auth
- Google Auth
- Translateable Email Templates
- Enable/Disable Sign In or Sign Up
- Password Reset Flow
- Update Email Flow

There is still a lot to do, the code base is full of experimental ideas and there a bunch of things to clean up, but first I want to focus on writing documentation and guides before adding more features.

Besides the missing documentation, what are you missing?
Interesting! So maybe there is a safe place to try it when I retire and have the time.
I'm a ex-Google SWE that's coached 300 through the FAANG interview process. AMA
My name's Darek Johnson and I run a company that's helped mentor over 300 to get FAANG-level SWE jobs for no upfront payment. I also used to work at Google.

Thought I'd reach out and answer any questions you have about software engineering in general, preparing for software engineering interviews, how to get a big-tech job, working at Google, or anything else interesting.

If you're interested you can check out my program - https://www.coachable.dev/

The problem if we have to guess then the process isn’t transparent
It's still easily twice as fast as trying to do the same route by car.
Well not exactly $5, it's in the same cluster, so.. hard to put a price on it. Plus a couple bucks for backups on B2. Oh plus the persisted volume.. I think I've got 25 GiB at 10c/GiB so $2.50 for 'hot' storage and maybe another $2.50 for 'cold' storage. And then it's running on like a $20 or maybe $40 node which I share with some other stuff. Anyway, not much!

For managed, I don't think I'd want to go lower than the $50 plan which would be roughly equivalent to what I have now.. would include storage but not backups I think.

But ya the data is valuable.. I'm running nightly backups. I want to do continuous backups someday or have some way to not lose up to 24 hours of data if something happens.
This is a complete lie.
> we don't factor in pollution externalities into costs

Suppose this is solved and it turns out your local electricity price literally doubles from $0.10/kW-hr to $0.20. Suppose your Electron app adds 10W to what you'd otherwise use, for 10 hours/day. Your power bill just went up by 1 cent per day, almost unnoticeable to an individual.

I actually agree that to understand why the software ecosystem is screwed up in the ways it is, we should be looking for the economic/legal/otherwise systemic incentives driving the patterns. But that's different from "I can think of a way the world is bad according to my politics, that must be it."
This is why I switched to $10+ tiers on Patreon, and later, Ko-fi. Less than that and you get a lot of impulse pledges. Most of them are fine, but it only takes one person who didn't read what was on the pledge page clearly to make trouble. At $10+, you get people who are mostly there for the journey and aren't troubled if you make big changes. The flexibility is worth not getting a few bucks from people who don't read before buying.
Thanks for explaining and creating the gist! Makes sense now that everything (* / + -) needs to be done modulo 61.
Hypothetically there is a common root source further back from your friend. IE a new book/documentary has people talking and the general buzz triggered both your friend to comment and Google independent of each other.
in new zealand men are practically not allowed to work as teachers for that reason.

this is a shame really. teaching is the one profession where gender parity should be enforced by law because kids need the rolemodels.

i spent a year in a US highschool, and the teachers i had there were fantastic. my teacher in US history was most enthusiastic, and i enjoyed the class despite failing it.

that was a few decades ago. and already then it was known that teachers don't get paid well. my conclusion then was that the one good thing that comes from low pay is that in order to become a teacher you have to really love it.
Yeah but it just kept happening so much with regular browsing I decided it was simply not worth it
Ask HN: Why are people still publishing bad math textbooks?
For those who only read through one book per topics, you are not the audience. Because at least you don't seem to be able to judge whether a book is good or bad. I dump any book as soon as I notice that it is bad, usually within 30 pages, and find another one.

I personally used 4 books to learn Linear Algebra last year, and ever since then I hated math textbook so much that I think I will never read any of them again, despite the fact that my HDD is full of math books. Because those authors usually leave blanks on somewhere maybe it is important, and I am so nervous to fill in any gap that may exist.

Some books are just objectively worst written. Like famous Strange's linear algebra textbook. That seems easy at the first glance, and then the learning curve is just skyrocketed to nowhere a beginner can make sense. I mean, how would someone teaching LU decomposition in the INTRODUTION part of the book???

And many recommends 3B1B's linear algebra series, but I don't think that is a great material. He is a great animator but definitely not even a good teacher. Those who experiencing the same frustration watching his videos may understand what I mean.

The problem of major math textbook is that notorious "leave it as an exercise" or "you should prove it yourself". I am here to learn, not "self-taught" self-taught. If I knew how to do that, then I don't need you. I need you (the book) because I want to know. But in order to learn a thing, first I need to learn how to prove. Then I need to learn how to prove a proof. Then again learn how to prove a proof of a proof...
You get the point, it is a dead loop that is so obvious to any programmer.

Yes, I even read logic and set theory book and it told me to prove everything myself. But somehow I don't know if it is a typo or what, the LOGIC BOOK is showing wrong thing to me. So bye-bye. Typo is fatal to a math textbook.

There are few books that I don't hate thus far.

One is the Mathematics of Quantum Computing from Springer written by a Dutch guy. He proved that yes we can have a book that is so comprehensive and "author-proof". There is none unproved theorem inside the 800 pages book. All steps are printed there explicitly.

And Stroud Engineering Mathematics is exceptionally best written for the narrative and educational approach.

And maybe the Openstax Calculus. Author provided all important proofs and for those omitted, I never feel any loss.

Especially in mathematics, books are written in Latex, mostly words. Only words are in the book. I wish they can draw more venn diagram and flow chart or something like that, to augment the intuition.

I think it is non sense to set up barricade against learners. Every non harmful knowledge should be accessible to anyone and this will aid the society and the world also reduce climate effect (no one ever need to spend 6 hours googling to find out the solution).

So IMO making math harder than what it is and what it should be is basically pointless and it is causing damage to the humanity. Those professors thinking the opposite should stop writting anything.
Wide-scale game piracy can be very profitable

Possibly but who is going to pay you $20k to realize these theoretical profits? They essentially mean un-networking your console, never updating it, only using physical media, likely losing your PSN account. There's a huge leap from step 1. 'an exploit exists', step N 'lots of hacked consoles and people buying pirated discs for them' and whatever step 'PROFIT' appears in. A latent market for free or cheap stuff is not the same thing as a market for this exploit.

If you dig into the actual data cited in the paper, the assertion that recovery was demonstrated at T3 is dodgy at best. The study authors may have put some reassuring language in their commentary to get past political roadblocks to publication. I would not have added the quotes myself, but they're not necessarily misplaced.

My mistake. When you responded to someone asking what teachers did all summer, you responded in a way that made me believe you thought they did. But now the question is, if you weren't saying that teachers work all summer, what was the point in itemizing the things they have to do each summer? Maybe you responded to the wrong comment? To make things easier, I'll bring back some context from earlier in the thread:

> Teachers are still required to plan and get ready for the next school year over the summer. . .

I thought this was more or less the entire topic of interest. That, and how much teachers work. What do you think the conversation is about? Pretty confused how you could think it's not relevant. You were needlessly combative earlier, so I guess I could chalk it up to that.
And they have an RSS feed. Nice. Added to my reader! Thx.
Shouldn't demand for teachers be roughly correlated with where everyone else is located? It's not like with tech where the employment is concentrated in particular areas.

And the big one - for me - it's noisy! Bikes are utterly silent so you don't spook wildlife and the locals tend to be a lot more friendly than if you disturb their neighborhood with your motorbike.
That’s not just supplies for me. It’s supplies for my team, for office activities, for user events, etc.

My point is that many people buy supplies for their work, it’s not unique to teaching. It’s surprising that it’s brought up as it it’s some unique factor.
Wait what the heck are they doing to books?
It's required very little maintenance so far, and it may even be a positive ROI because I'm using the same setup for development. Since it's part of the same Kubernetes config, it's easy to spin up the DB under Docker Desktop for home development. I don't know how I'd do that with a managed solution.
Yes, they do, they are. It sucks. Logitech is the worst. I've bought some of their (not cheapest) mice and they all started double-clicking in 6-12 months!!! And when I tried to resolder switches on my G100 the tracks started to peel off the PCB - and I'm an experienced engineer. I ended up switching switches with a cheap A4Tech lying in a closet. And these still work. Shame on Logitech. In the era of M-SBF96 they were making reliable products.
I still don't see how you can determine an object's attributes without type information. If you're inside the function, all you know is there's a parameter named item. How can you provide autocomplete there?

All of the examples you gave are from static languages, where the information is known at compile time (except for valgrind, which requires a runtime). The parent to my original post was claiming that you can have the same tooling for Ruby.

Also, you're wrong about Rust. Lifetimes are part of the type system.
I didn't know about wave collapse functions before stumbling about Townscaper. Still, I found them hard to understand until I found this video by Martin Donald: https://www.youtube.com/watch?v=2SuvO4Gi7uY

Now, I'm just looking for a use-case to implement them myself sometime.
> Specifically, when learning a new field of math, the proofs sometimes don't feel rigorous to me right away, but once I get used to the the basics and the linguistic conventions, I'm more able to fill in the holes in my head

the most complicated proofs i ever dabbled in were things like proofs of convergence for algorithms, but i encountered various types of proofs in several intro courses: computability and theory of computation, discrete math, introduction to higher math and then some upper div cs courses in ai/ml.

what you say here rings absolutely true to me. as someone coming in with a long time background in coding and computers, i always found myself wanting to apply the same unambiguousness and precision that one uses to express computations in a programming language in mathematical proofs. this was a huge stumbling block for me! proofs are written in shorthand (!) by humans for other humans who have the same base knowledge, obvious things are omitted. once you have that knowledge it makes sense, but before that it seems like giant leaps are being taken without a rigorous line of reasoning between them.

to answer op's question: "an introduction to mathematical reasoning" by peter eccles was helpful for me. it's basically an expanded version of what you'll find at the start of many intro cs/math courses. another option, if sets, number theory and such are confusing to you is the computability angle (cs theory, computation). personally i found this material a lot easier to reason about which then imputed confidence, which is really the magic ingredient for good proofs.
That's not what the programmers want. It's how they're incentivized. If you have to meet your "they're not deadlines but, really, they are" sprint targets, then what can you do but minimally complete the tickets assigned to you and hope not to step on anyone's toes?

It doesn't help that good programmers get flushed out of the industry due to conscience and age, only to be replaced with cheap, shitty ones.
There are 6 people using my ip regularly. We all get a mishmash of eachother's YouTube recommendations.

I'm frankly surprised to find some people in this thread don't already know that ip correlation is going on as a matter of course.
Regardless of which text you choose, I recommend writing proofs (full sentences and all) for the solutions that were harder to come by, or you feel difficulty expressing clearly. And if you can, get some feedback on the proofs. (Happy to take a look at a few if you DM me)

The process of writing will hopefully help you:

- build awareness of when your arguments are not airtight or when you make false assumptions
- modularize your thinking
- become more fluent with logical "vocabulary"

As for books, my personal favorites were Problem Solving Strategies (Engel) and Art and Craft of Problem Solving (Zeitz). They're both really approachable, have plenty of examples, and will give you a different perspective on what math can be about.
