skysight-inc/HackerNews huggingface dataset:
I was a public school teacher that worked in a district that attempted to measure teacher value add. There was limited pay for performance based on that metric. And the district I worked in was majority racial minority and majority living in poverty.

"Using the expiration of preexisting collective bargaining agreements as a source of exogenous variation in the timing of changes in pay, I show that the introduction of flexible pay raised salaries of high-quality teachers, increased teacher
quality (due to the arrival of high-quality teachers from other districts and increased effort), and improved student achievement."

"The main dataset contains information on the universe of Wisconsin teachers,
linked to student test scores to calculate teacher VA."

"Student Test Scores and Demographics.—Student-level data include math and
reading test scores in the Wisconsin Knowledge and Concepts Examination (WKCE
2007–2014) and the Badger test (2015–2016), for all students in grades 3 to 8, as well
as demographic characteristics such as gender, race and ethnicity, socioeconomic
(SES) status, migration status, English-learner status, and disability."

What this study is saying is that paying teachers more for improved performance by their students on standardized tests results in higher standardized test scores of their students. That does not surprise me. In my experience, this system encouraged teaching to the test (focusing the majority of instruction on test prep rather than traditional instruction) and widespread cheating. Both of these efforts raise standardized test scores. The study assumes that standardized test scores are a direct measure of teacher quality and student achievement. In my experience that is not true.

One thing I absolutely love about online discourse: shit all over someone, then block them. It is something that you don't see with in-person communications - because you really can't just "close off" the discussion to one way.

Anyway, I just think that people do things in online discussions that they wouldn't do to someone's face. And that tends to be a bad thing for reasonable discourse.

>And the places that get left behind…?

Think of it as government-performance based teaching quality variations.

>But in the short term, this scheme seems likely to redistribute talent in ways that reinforce existing patterns of inequality.

Only if disadvantaged districts are less likely to switch to performance-based pay. What is the basis for thinking this will happen?

Firstly, IRC is not a Product anyone is trying to sell, I am an IRC evangelist, advocating for an old but adequate technology that can be configured to add the functions that people demand. IRC is not a Product, we are not salesmen, we are Enthusiast. This distinction is meaningful enough to merit pointing out. Do you think when I came to IRC, I didn't notice that the UX was actually rather ugly?

It was readily apparent to me, I simply felt other things were more important. It wasn't the priority.

The same is true of money, being able to take part in the gift economy of the hacker under world is of more value to me than money.
The language is the easiest part. It's fairly simple, ergonomic, and actually pretty well made.

> let's not spread the myth that a heat pump will leave you freezing once outside temperatures drops below a certain threshold.

That is not a myth - I have a heatpump in my house and it will leave me freezing on the coldest days. The system is sized so that it cannot keep my house warm at -5C (the system can deliver heat, but the house will cool down). Worse, it did get below -25C here for a couple days which is as cold as any heat pump will work - I don't know of any house that is insulated so well as to be warm when the outside temperature is below -25C for a few days without some heat - but mine isn't one.

A correctly sized heat pump can keep your house warm to -25C, but if the installer doesn't give you a correctly sized system it will not. Most installers don't know how to size heat pumps.
The difference is that it's not a human, it's a machine designed to do that. There was a choice, that's the difference.

FWIW, my assumption here is that people who publish like this page are expecting users to use a "reader view" and they're trying not to introduce any styles at all, so as not to conflict with the styles that the reader view will apply.

Otherwise, ' "reasonable default" for lots of text ' is something that browsers provide, using the "system" fonts. Applying a font-family to the entire html or body tags will do the job, because system fonts don't need to download or load into the browser. And since you can even specify the specific system font you want to use, you have a few options like serif or sans-serif.

All of that aside, if I applied a system font and your screen reader applies a different one, what was the point of the extra css? So that's my guess as to why people do this because, like you, I find it very hard to read.

If you're curious, though, Firefox has a built-in reader mode and I think Safari does, too. Last I checked, Chrome's was behind a flag. And then, of course, there are extensions (but extensions to read plain HTML docs seems exactly backwards, so...)
Or you could simplify the whole thing and just host it yourself. It isn’t worth that level of complication.
I think it’s more reasonable to think about it in relative terms to the cost of living in an area. Yes, it’s healthy to have perspective, but a 2BR in NY can cost well over 1.5M, and the cost of just existing in a city makes a world-definition of wealthy somewhat less relevant for many.
Sadly members of my own family openly voted Brexit, despite my grandma, my sister and myself all being EU immigrants at the time.
According to Goldstein, The Theory and Practice of Oligarchical Collectivism (appearing in [Orwell49]), there are two possible governing coalitions in any society: Low+High (vs Middle) or Low+Middle (vs High).

If both Low and Middle were to agree the High ought be taxed, it would be to the High's advantage to stoke culture wars between Low and Middle in an effort to ensure the first coalition.

Sure, but if the gains in an experiment come from cannibalizing other districts, then it's not a good guide to what will happen when everyone's in the experiment. Do you attract more people to the profession? Or do people get discouraged by seeing variable outcomes they can't predict ahead of time?
The previous administration brought an enormous amount of pressure down on the Fed, and a new version of that administration will likely be much more focused. Combine that with major tax cuts in our current fiscal environment, the result is not likely to be pretty.
I did not know all of this about the org. The t-shirt situation is just unfathomably stupid, that last line about anonymity might convince me to cancel.

I still do like the product they offer, though. It'll be difficult to give up their bullshit result filtering. I also cancelled my ChatGPT plan because I could use GPT4 through Kagi. They also provide access to Gemeni, Mistral, and Claude. Probably actually an unsustainable value.
Neither Greece or Italy seem to be on the brink of a new civil war, nor do they have more owned guns than inhabitants (AFAIK). If anything, instability in these countries mostly means more opportunities for people with lots of money.

We moved to heat-pump a few years ago and disconnected from gas. It's been working great. Our biggest expense was insulating our house. It is an old house and the 2nd floor was very drafty. You could feel a breeze coming through cracks in the wall. When we opened the wall there were just a few newspapers in there and no insulation.

We had the 2nd floor siding removed, an extra layer of insulated wall added to the outside and then cladded with siding. It was like putting a big insulated hat on our house. Now the temperature is very consistent and absolute no drafts.

The architect said to me that we'll never fully recoup our costs of putting the hat on the house. To which I replied that we don't always to things for economic reasons, and just do them because they are the right thing to do.

My only regret was going with a Rheem heat-pump water heater in this mix. It does not perform well at all. With hindsight I would have looked for a way to perhaps have water heating integrated with our air heat-pump system. There is a company called Arctic that has those systems.

Also with regard to heat-pump water heater, out big problem is that a hydronic floor heating system (installed when we were on gas) is now constantly drawing off heat from our tank. I'd like to find a small standalone unit to handle floor hydronic heating separate from my main water heating.
I don't think that stability of a country is a simple function of tax rates.

France has the highest taxation in OECD and it is internally very messy. Switzerland much less so.
How would it reinforce existing patterns of inequality if low-income school districts move to a flexible pay model, thereby attracting better teachers?

An other more direct issue is Goodhart’s law: if teacher compensation is linked to a specific metric, then that metric is what you’ll get. If the metric is test scores, then you’ll see:

- teaching to the test rather than educating

- trying to get rid of left behind, slow, or difficult students (already an issue for generations in test-oriented private institutions — as opposed to the more remedial “last chance” ones)

- ignoring the groups which have the lowest odds of contributing to the metric (which groups it is depends on the weighting / averaging between pupils)
I'm suggesting that self owned companies are allowed to and often do spend absurd amounts of their spare money on pointless things like marketing or internal transformations.

The difference they don't tell you about their internal accounting so you don't join the dots.

Start ups burn money on silly things like offices way too nice for what they need all the time. That's much closer to unethical than a company with no real duty to outsiders throwing away money.

I was giving them the benefit of the doubt up until this. Wtf? I’d be happy to wear a brand t-shirt “Kagi” and that’s it.

What an own goal. I’m sure it made sense to them but I’m worried they don’t truly understand their customer base.
I really love using Kagi Search. It’s awesome. I think Arc is becoming very similar with all their AI features that are kind of boring, but that their team is obviously focusing on.

It is quite strange that they are doing all these other things that I basically don’t use at all though. Classic entrepreneur chase shiny objects and get bored with the core idea. In their defense though, people do believe that search is going towards an ai future.

But I do want to say that Kagi Search is really awesome and I hope it works and I won’t go back.
No clear answers? The world is teetering on the edge of world war, young people will never own a home or anything really, wealth inequality continues to get worse, social media is tearing apart the fabric of society, people are constantly inundated with negative news(yes I understand the irony here), among a million other issues. They are right I suppose. There are no clear answers because everything seems fucked.

Yep - The cost of housing, education, health care, and retirement require a different calculus than living in most other countries.
Hot take: you need to define performance and you can't without market feedback. So being about to freely chose a school and direct your money to it has to be the first prerequisite to even thinking about performance based pay. Some bureaucratic performance definition will just have people optimize for that.

My point was that the professional side of PHP developers at that time, decided that they want to have a strong type system.
A counter argument I've seen - with auction only IT companies will be able to hire H-1B workers and other industries like healthcare and pharma and even chip production will be out-priced. Different industries have different level of salaries. $200k/y salary may suppress SDE wages in Silicon Valley but it is well above market rate for an electrical or a chemical engineer.

Yes, this kind of behaviour is keeping people away from research, except for the ones who are fine with it which of course ends up encouraging the bad behaviour. I'm sorry to see the disappointment evident in your comment.
My fear as well. Is there a better way to assess teacher quality, especially in challenging student environments?
Is the statement "monetary rewards for performance improve overall performance" considered bias, or just common sense?

I'll take it a step further than this. It doesn't matter if the client wants unit tests or not. If the developer has been hired to do the job, it's going to be up to that developer whether or not they feel unit tests will make the code better. If they do, they should do them. If they don't, they shouldn't.

Caring about the client's opinions re: unit tests is a little like caring about their opinion re: the interior color of your vehicle. Sure we can talk about it if it comes up over a beer some Friday evening but we're certainly not going to change anything based on the conversation.

But, FWIU how this applies to line length and transmission time hadn't been tested until Veritasium's experimental video with CalTech with like a mile of cable: https://youtu.be/oI_X2cMHNe0

So, it doesn't need multiple length parameters.
The implication being that countries with more taxes can afford to waste money by paying bad teachers well?
I agree. Something that is emblematic of the problem: Nix has an implication operator. That's something that virtually no other language supports - it's normally something found in formal verification systems.

The Nix language is designed by people that think everyone is familiar with lambda calculus and function programming. That's fine. But it's crazy to use a language like that for something that everyone has to use.

I bet Nix would be way more popular if it used something like Starlark instead.
> and they have fully bought into AI being the future of search

Good, because as far as I can tell it is. I use their "Quick Answer" feature very often in my searches, to the point where it's the first thing I click when searching. It's fantastic on mobile so I don't have to go trawling through ad-ridden websites. I am a happy customer because of this feature.

> But the developers of Kagi fully believe that this is what search engines should be, a bunch of AI tools so that you don't even need to read primary sources anymore

At least with "Quick Answer" it links to their sources used. This is a non-issue.

> There was some demo where you could put someone's Twitter handle in and it would give you a summary of who that person was (nightmare shit)

Really? Providing a summary of someone who willingly posts publicly is the stuff of nightmares? This is not a serious person and their opinion should not be taken seriously.

> And he is very, very much the type that believes "not everything is political" and "we don't get into politics"

Because not everything is political. I have never met a stable or amicable person who has thought that everything is political. Every time they have had a coarse personality that has a warped perception of reality. If I had a discord channel for my product and people were going into it mucking it up by trying to make everything political, they would get a swift ban. Keep that shit on Twitter.

I see a lot of their extra features as just that, extra. I don't buy Amazon Prime because I want to use "Twitch Prime" and "Amazon Music" as well, I buy it because I want faster shipping times. The rest is just extra and is of no concern to me.

A third of their investment on free t-shirts aside (which ain't good AFAICT), most of what Vlad is talking about comes off as reasonable. The only thing I do take concern with is his stance on <100 people on earth who really need anonymity. That does not inspire confidence.

This is one thing I never understood about web development.

I would have thought the risks from 3rd party production dependencies would make devs do all in their power to minimize them. But IIUC it's a somewhat common practice.

Is there something about the market dynamics that make this a reasonable tradeoff? E.g., the problems are rare and this somehow allows faster time to market?

We frequently put the burden on teachers and “the system” for outcomes, but rarely do we talk about improving our cultural and societal attitudes towards education. If you come from a family and community that does not value education and views it as free child care, how good your teacher is does not matter very much.
