When I was in school for my master's degree some years ago, several of my classes were heavily populated by teachers (New York State requires teachers to have or get a master's degree within 5 years of being certified). All were humanities teachers (English, Social Studies, ect - no STEM). At least half of them had great difficulty simply writing a one page essay. With one or two exceptions, reading comprehension was absolutely abysmal. At least two of them were functionally illiterate (in a master's program!). All were certified teachers who were actively working in schools.

The fact is that in many places school standards have been so low and social promotion has been going on for so long that we now have people coming out of high school and college that have never achieved anything academically. Many of these people go into teaching (even when schools were academically rigorous, majoring in education was always regarded as one of the least challenging areas of study).

That isn't to say that there aren't good teachers, or that there aren't smart teachers - there certainly are. It is to say that having an education degree or a teacher's certificate does not mean that one is qualified to do anything.

Does this mean every parent is smart enough or cut out to properly home school their child? Of course not! What it means is that (many) schools have effectively failed as institutions and until they are improved many people are going to look for alternatives.
Most FHE schemes are constructed out of SHE schemes. Also, there’s nothing preventing FHE from being practical, it’s just that existing constructions are not as fast we would like them to be
I have been looking at homeschooling because of the 2 Sigma Problem.

All known FHE schemes use bootstrapping
Great advice, especially in the second tab (how to deal with insurers).

I've always considered insurance false-economy and avoided it wherever possible, especially for events with losses <$20k. This is because the value of the three time-costs of insurance (time to find, time to monitor, and time to claim) generally exceed the expected value the claim.

For example, if my flight were cancelled, I might lose $1000. But all the hassle signing up for, monitoring (to ensure conditions don't change significantly in the insurer's favour; often conveyed by an email to a spam folder), and going through a stereotypically labyrinthine claims process is significantly worse than being out of pocket $1000. Or another way to put it, I'd pay $1000 just to avoid having to do all that. Or a third way to put it, if someone offered me $1000 to find them a suitable insurance policy, monitor it to make sure the company didn't spontaneously alter it, and make a claim on their behalf, I wouldn't do it, it's just not worth it.

I get why insurers are like this. If they can sneak you a letter/email(/fax) and on in a foot note on page 43 'notify' you of a reduction in your coverage (for unchanged premiums), they make money. And if they make lodging a claim as onerous as possible, some % of claimants will abandon the claim, making them even more money. So insurance companies are just doing what they're legally allowed to do to make as much money as possible.

Where possible (e.g. for events without enormous payouts [obviously not so helpful in the case of LA fires]) it can be better to DIY insurance, i.e. put a little savings aside for those events (just as one may pay insurance premiums), that way, you actually have it when you need it, unlike insurance payouts from insurers who generally try to make it as difficult as possible to obtain.
Ah, I wanted a setting explicitly. I'd like to preserve my watch history, i only want to disable the home and recommendations.
Meta to lay off 5% of 'lowest performers', plans to hire for impacted roles
It is one of the better paying jobs and Nepal makes a mint from the permits. They pimp themselves out for a buck defiling the mountain with their trash and corpses. And I don't blame them, it is what it is, a weird symbiosis of mountain exploiters all the way down. If the locals care about that they'd at least require sherpas for hire to haul out the corpses who signed their checks.
I ride and work on motorcycles a lot.

tl;dr: Front wheel fork angle causes uprightness, the overall cause of turning is due to tire shape and contact patch at lean. Countersteering is the input to start and maintain leaning.

Bicycle and motorcycle physics have a lot of different forces at play, but the main one for keeping the bike upright is the front wheel, causing corrective steering at lean.

When a bike starts to fall, the rake angle causes the wheel to "self correct" and steer the bike towards uprightness. With speed, the bike wants to stay upright and will self correct.

To steer at low speeds (most bicycle speeds), you actually turn the wheel in the direction you want to go very briefly, "fall" into a lean and switch quickly to counter steer in the other direction, keeping the bike upright.

At high speed it's a bit different. You don't need to initiate the turn. You can just skip straight to counter steering, which forces a lean and causes a turn. At speed you are constantly upright, so you need some input to tilt the bike.

The effect of leaning to the right with the wheel self-correcting left, is an overall arc to the right (vise versa).

As for gyroscopic forces, these are at play but the force is negligible for keeping the bike upright. Heavier wheels have higher angular momentum, making the bike a bit harder to force a counter steer. They also affect how quickly a bike can accelerate given a certain force.

Can this use a cloud browser API like browserless?
feels like i somehow only applied to the fake ones during my last job search. outside of the us for context, so should rule out the h1b explanation. seen many of them staying up for months on end, and getting reposted on job sites as if something just came up. many happen to send rejection mails when they finally bother closing them in their crm.

while i still worked on applying and writing custom cv/cover letters the "old-fashioned way", i don't envy the past where you'd do the same paperwork physically. but it is very draining and frustrating given how many more openings you end up applying for compared to the analogue yesteryears.

getting on the employment train is hard, but for most people you could then just rely on personal network and getting reached out for newer opportunities.

> To put it another way, the best side businesses -- and indeed the best jobs -- are getting paid for things that are like the things you would do if you did not get paid.

I feel the complete opposite.

The things I really really really enjoy doing with my time are not (realistically) for sale. They are for me.

If you said I could make $250k a year by reading 100 books a year (a bit less than what I read on my own), I’d think long and hard about accepting.

I probably would because it would be interesting to test my assumptions, but I’d imagine it’d be less fun that reading them for free.

Show HN: An Android app that scans your Obsidian notes to set reminders
I'm an on and off Obsidian user who recently came back to Obsidian again. As flexible as the app is, one thing it can't do is set notifications on mobile devices. The feature seemed to be in demand on forums, reddit, etc but it's not on the Obsidian roadmap. So I figured I'd create a free app to set notifications from your Obsidian notes!

It's called Notifian and it's a "companion app" for the Obsidian Android app. It scans your Obsidian vault folder and identifies reminder properties in your notes to set:

- An initial reminder date/time

- (optional) A recurring schedule for reminders

- (optional) A "stop on" date/time, to stop scheduling reminders

It runs these scans in the background on a recurring interval and, as a bonus, it also has support for the Obsidian "tasks" plugin's task format!

The app just got out of closed testing and onto the play store, so I'd love to get more feedback on it now that it's released!

Public and private schools don't take the same tests, so we don't have good days to compare the schools. Even if we did, it would be hard to disentangle the impact of selection bias.

You could look at college acceptances or similar, but those aren't unbiased either, as colleges look at estimates of class rank, not just absolute performance.
>In the other 127 schools, what percentage of students were proficient in math?

Citywide the number was 7%. Better than 0 I suppose but still awful.

>Just 7% of third through eighth graders tested proficient in math, which means 93% could not do math at grade level.

Resistive heating generates heat: thus, it cannot generate more than 100% of the energy put into the resistor, because of conservation of energy.

In contrast, heat pumps move heat, so they can move more than the energy put into them. Even cold air (around freezing) has a lot of heat in it to siphon off.

If you're going to run 1MWh worth of compute anyway, then selling the waste heat is still a good idea. But if you weren't, a heat pump will get you more heat energy than a bank of computers with the same energy budget.
> It's only recently that the average people have had the chance to become elites, rather than be born into it.

It still mostly depends on being born into it. In the US your odds of going from impoverished to wealthy are extremely slim and socioeconomic mobility is among the worst compared to other developed countries. The US falls behind South Korea, Lithuania, Estonia, Singapore, Malta, and Slovenia, while the Nordic countries top the list.

Depending on the study, socioeconomic mobility in the US has either stagnated since the 1970s or actually declined. Average people have little hope of substantially improving the situation they were born into while the percentage of people born into wealth (but not the 1%) who slide downward in socioeconomic status grows. Wealth inequality continues to accelerate at an insane pace. (https://en.wikipedia.org/wiki/File:1962-_Net_personal_wealth...)

Just about everyone would like to be one of the "elites" but most people would be happy with a fair chance to meaningfully improve their lifestyle.
The moment I read the title I knew exactly how the comment section was going to look like. I was not disappointed.

What do you consider the "proper education"?
If you are blindly relying on certified professionals in soft fields such as general medicine and law you are in for a bad time.

At a minimum you need to use your judgement to vet good from bad practitioners in those fields.

Also "disrespect our educators" is so funny. Sorry, they're not that serious, mostly dumb. And we're not the laughingstock of the developed world, we are the rulers of the developed and undeveloped world
Seems like the only billionaires you can name are the ones that made the news in the past week... How about the "silent majority" of Bill Gates, Jeff Bezos, Larry Ellison, Sergiey Brinn, Lary Page, Warren Buffet, Steve Ballmer, etc? Are they all "anti-woke" as well?

I guess my point here is: until recently "wokeness" was the mainstream ideology, basically the default setting for all the rich and powerful. Yes, recently half a dozen of billionaries switched sides, but that does not mean that wokeness doesn't still have trillions of dollars behind it.
It's about exposure to the way richer people think and access to the same community resources. Property taxes pay for schools. The best schools are in the richest communities.

That’s my general understanding as well, but it isn’t a large conceptual leap to go from real-time selection of pretrained “z-vectors” to real-time generation of the same. The larger conceptual breakthrough, with demonstration of its effectiveness, is the big success here.

There are some rotten incentives at work here, as well as constraints that aren’t obvious from a parent or student’s point of view.

For example, CA schools have to publish statistics on suspensions and expulsions. So there’s an incentive for administrators to minimize them. In practice, this means that expelling a student (short of some extreme situations) is a lengthy process of ass-covering. Even when administrators are doing the right thing, from the outside it can look like nothing is being done. Think HR putting you on a PIP.

Meanwhile, the “right thing” isn’t always so obvious. The “violent and disruptive” student is also a child with a right to an education. And for what it’s worth, usually a child in crisis. For school staff, your role as an adult is to teach the child to participate in society with whatever limited influence you have. As a parent or classmate, of course, you have no reason to give a shit about some asshole kid, but the teacher has to.

And then, what does “violent and disruptive” actually mean? How much violence? No tolerance? What about a bullying victim who sticks up for themselves? Playground scuffle? At what point does the dial turn from teaching a child not to hit, to teaching a child that they are bad and do not belong? What about non (physically) violent bullying? What about children who are disruptive, but not violent (surely including a lot of those posting here about how their ADHD was misunderstood)?

Sometimes expulsion is the answer, even keeping in mind that every student expelled before 16 is just going to school someplace else. But the problems are more complex than people often realize.

>Why can't it keep going?

Because an educated populace is harder for the ultrarich to control and abuse, because an educated populace with free time can revolt against those in power, and because as a consequence of those two things ultrarich conservatives have consolidated ownership of media and used it to defund education and convince the population that funding education is bad.
SHE vs FHE has nothing to do with security. Instead, it’s about how many operations (eg homomorphic multiplications and additions) can be performed before the correctness of the scheme fails due to too much noise accumulating in the ciphertext. Indeed all FHE schemes are also SHE schemes.

What typically makes FHE expensive computationally is a “bootstrapping” step for removing the noise that accumulated after X operations and threatening correctness. After bootstrapping you can do another X operations. Rinse and repeat until you finish the computation to you want to perform.
Dylan was definitely on the cans. The demographic that drinks Bud Light that likes Dylan was definitely a minority as the overwhelming majority of its loyal consumers rejected it overnight.

I think its lazy to blame politics for a failed marketing campaign by creating some vilifying your own consumer base. We see the same pattern playing out in all aspects of products that have gone woke, games serving as the most recent example.

We live in a capitalist society and consumers will vote with their money and they cannot be forced to buy a product because the media and special interest groups decide to vilify and defame them publicly. This might work in a communist country but even then the effects are short lived.
> I've had a staff SWE also claim to me that they generated colliding UUIDv4s, and a separate staff SWE who worked in GIS claim that circles only exist in map projections and they're always distorted, and that you cannot have a circle IRL, nor project it onto a projection.

The claim about circles I don't know. It depends on what exist means, and I don't know what it means to have a circle in real life, and likely don't care. I can only draw a rough approximation of a circle, and that's been fine for me.

Generating a colliding UUIDv4 seems pretty simple though; if you have a broken enough random generator setup and manage to run it without seeding, especially if it was in the times where it was pretty easy to run a virtual machine with totally broken random (virtio-random was developed for a reason), and spawned a bunch of virtual machines in very similar conditions. You can no true scotsman your way out of this by declaring that a broken system, but from inspection, I don't know how you can determine if a given UUIDv4 was generated with proper or broken random techniques. See also Debian Security Advisory 1571-1 [1], and similar issues where random values that were intended to be secure turn out to be predictable. It's a plausible claim. But that doesn't mean a claim by a 'staff engineer' is default plausible. It's just an appeal to authority of a title that doesn't mean a lot.

> It is to say that having an education degree or a teacher's certificate does not mean that one is qualified to do anything.

Backstory: I wanted my own SIEM (Security Incident Event Management) dashboard but everything that is worth using costs way too much money. Right now the SIEM market is catered towards large enterprises and hence they cost anywhere between 5 to 6 figures USD to run as a service. I wanted to make something that SMB's can use. It has flat pricing. It can stop brute force attacks on Windows 10/11 out of the box and can push security related events to the cloud. The Standalone Windows agent is free, in the future I want to make a local open source version that pairs with it like pi.hole (DNS sinkhole that sits on your network and blocks ads).

This project started in June and I have done a soft launch in late December, I will be doing a hard launch within the week.

This is where reasoning models come in. Train models on many logical statements then give them enough time to produce a chain of thoughts that’s indistinguishable from “understanding” and “thinking”.

I’m not sure why this leap is so hard for some people to make.
It compiles to SQL, so in since sense yes it is schema dependent. As mentioned in the article DBT itself has no understanding of semantics, so it’s not enforced by DBT directly but if it doesn’t compile to working SQL expressions it’s obviously not going to work.

I'm not quite sure what you're visualizing for compilers, if I understand correctly, what I'd say is:

tl;dr: there are general optimizations for "this function in a for loop is a constant expression, we dont need to call it 500 times"

or

"this obscure combination of asm instructions is optimal on pentium iii 350 mhz dual core"

not "we need to turn this unholy CS101 student spaghetti code where they do a 500 branch-if into a for loop"

comment over here is attempting to communicate that as well https://news.ycombinator.com/item?id=42705758

I've never, ever, heard the idea that compilers are burdened by the workload of maintaining thousands of type-specific optimizations for hilariously bad code, until today. I've been here since 2009, so it is puzzling to me to see it referred to off hand, in a "this is water" manner https://en.wikipedia.org/wiki/This_Is_Water
