This seems erroneous "~50,000 DAU (1.4M MAU)". It can't be true that the average monthly user only interacts once per month (1.4M/50k). How do you explain the figure? Dividing MAU by 30 would not be a good approach.

> my balcony is facing east. This means it only receives direct sunlight from 16:00 onward during spring and summer.

I’m confused. The sun rises in the east. By late afternoon it would not be directly shining on an east-facing balcony, would it? The most sun would be in the morning on that east side, I would think.

It's not mentioned in the article but I think there's a big gender split as well. This is only anecdotal, but my sister was told all the way through school that she wasn't good at maths, despite being in a Grammar School (requires an exam to get in). She ended up doing well in her exams despite years of criticism, and is now a teacher, teaching maths among other things. Again, anecdotally, I more commonly see women laugh off terrible maths skills as "oh ha ha yes I'm not good with numbers".

It's just sexism. From teachers to exams to parents to pop culture, we've decided that women are worse at maths which is obviously both untrue and incredibly damaging. Maybe we should be tackling that.
To a large extent, this is already known. Propaganda is a thing because it's effective. They don't call it "programming" for nothing. Media headlines and coverage shape puplic opinion. Oldest secret in the book. This is actively exploited by media companies as well as intelligence agencies, both foreign and domestic.

I don't think AI is doing anything here that wasn't already there. The scary component of AI is that deep fakes will be used to shape public opinion. It could go one of two ways: either people are repeatedly duped by the fakes or they lose trust in media altogether and withdraw from it entirely, for better or worse.
I'm not sure that question has an answer; the regulators are fairly ad-hoc which is why reviews take multiple years instead of happening quickly and it the flux in requirements seems linked to the cost overruns (otherwise the planners would learn and the cost estimates would have error in line with any infrastructure project). Seems doubtful that there are 'some regulations' static enough to be targeted. I have read a lovely article somewhere describing how the regulators interpret nuclear being cost-effective as evidence that the standards need to be raised but I cannot lay my hands on it. However - amusingly - while considering what a reasonable answer would be I discovered that the current head of the NRC appears to have been trained as a priest:

He has a master's from Yale Divinity School and Yale School of Forestry and Environmental Studies, and a Bachelor of Arts degree in Religious Studies from Valparaiso University. [0]

And previous members have been actively opposed to nuclear power as a concept:

After leaving the NRC, Jaczko called for a global ban on nuclear power. [1]

This is not an environment where reasonable and supportive people are trying to make nuclear power work. The NRC is a high-risk arena where the companies involved have confidence only that their applications may be reviewed by people who range between under-educated about the issues and actively hostile to their success as commercial ventures. There is a reason that the industry is almost alone in the 21st century as a technology that is getting harder to implement. That reason is a cult-like group of anti-nuclear activists who are willing to see people starve and freeze before they will allow a Fukushima to happen every 50 years. This is a significant contributing factor to why it is getting harder and more expensive to build nuclear plants.

This is silly.

Learning maths was fine for me, up to university level.

However I would not make the mistake that this would work for everyone, people do have different strengths. I would not have coped with e.g. Art or Music to that level, and there is no point in forcing maths on people who have those strengths. It's not one-size fits all. Aptitudes do vary and education should lean into that.
> Most of what we hear of the Fediverse is rants about twitter and a few of the same subcultures over and over again.

I feel like this isn't true anymore. There's definitely a lot of chatter about Twitter of course and even more so now that there's regular Twitter related drama happening. But I have 7 federated instances on speed dial that range from general purpose, to infosec, to art, and to game development. They all talk about a lot of stuff, not just the things related purely to the server theme. I checked all of their local timelines just now and found only one post talking about Twitter and it was just a link to a news item where Elon talks about government access to Twitter.

Notably absent were any growth hack posts. Everything was just stream of consciousness stuff.
I like how their "only 2 left on our site" is their example of "well this is alerting but useful, when exactly that tactic has been shown (in general, not on booking or at least I don't have that example at hand) to be entirely fictional. There simply isn't any actual shortage.

The US holds no monopoly on the concept of a federation. Germany (Föderale Bundesrepublik) is one too, so is India or Russia.

It's floor(_) - as in, floor(1.999) = 0, but floor(2.001) = 2. If you look carefully the upper flange of the [] square brackets is missing, which makes it a floor.

I've always disliked how wasteful streaming is in respect bandwidth consumption. However, the "efficiency be damned, just make it fasterer" attitude towards bandwidth is, if not the biggest, then definitely among the biggest, drivers behind the ever increasing internet throughput.

Thinking about it, it seems like watching habits could make streaming be more or less "efficient" compared to downloading once and storing it locally (depends on how one chooses to calculate efficiency tbh).

People that have things they regularly re-watch are obviously gonna benefit from having a local copy they can access entirely on their own terms.

It hadn't occurred to me until recently, but the way I watch stuff has me going through a pretty large amount of data yet I'm also excessively unlikely I re-watch nearly anything that I've seen in the previous 2 years. Whether something is streamed or stored local, it has to be downloaded the first time it's watched. If it'll take 2 years before I re-watch something, it's a waste of time and money to keep a backlog of multiple disks worth of video

(Had to check the TeX code to figure that out, MathJax let you do that with a right click on the equation.)
To illustrate "build build steps" with an example: I used to work on a project that had 1000s of Javascript files, that we compiled into a dozen or so webpack bundles to deploy. Not every webpack bundle depended on every file however. We wanted incremental builds, i.e. so that if you changed one Javascript file, you wouldn't always have to rebuild all 12 bundles (which took like half an hour) -- if only one webpack bundle included the file you changed, you should only have to rebuild that one.

You can get webpack to output a list of all the Javascript files that it used in building a particular bundle, but the list wasn't fixed from one build to the next. You could add new files or add import statements to create new dependencies. This is the situation the paper calls "dynamic dependencies".

We used "Make" to run our builds, and the way that we had incremental builds was, we had one main Makefile, and one of the tasks in the Makefile would run webpack, parse webpack's output, and literally write a bunch of sub-Makefiles to disk, describing the dependencies between webpack bundles and javascript source files. These Makefiles would then be imported into the big Makefile when a change was made and the next build was run so that Make had the dependency information and could decide whether a particular webpack bundle was stale or not.

Wanted to describe this, just in case a specific example helps you conceptualize what endgame calls "build step that builds build steps".

Incidentally, Make really sucks and this some of the buggiest, hard-to-debug, code I've ever worked with.

After reading 'Build Systems a la Carte' I decided to try reimplementing our build with Shake to capture the dynamic dependencies. The proof of concept worked like a charm and was an absolute pleasure to write, though I left the team before actually deploying it, for real. I hope the poor folks that came after aren't still wrangling Make...
I agree with the idea that medical doctors are not scientists, not even engineers. Yet I think it's impossible to do medicine as if it was a science: Most person is different from the next because their life events, and biology and medicine are incredibly hard.

For example we do not have models of human physiology, even if it looks something that could be computerized (there are efforts: dr Guyton's heritage, BioGears, etc).

Another thing is that we only had recently tooling to interrogate what's going on in our body: MRI and ultrasound. Yet no medical doctors (GP/family doctor) use them. At best they use blood analysis which gives an indirect knowledge. But if the doctor does not ask for the right analysis, whole health developments stay unknown until it's too late.

And many family doctors work with feeling more than with medical standardized practices: It's common that old family doctors say that they know what brings a patient as soon as they enter into their office. This is because of these "gut feelings" that we still have half of cancer cases that are discovered when they are metastasized (too late to be treated by oncologists).

Ask HN: Crowdsourced Open LLM training data?
Please excuse me if I get any details incorrect, I am not a LLM or AI/ML expert.

To make large language models useful we fine tune them. The Alpaca project used an OpenAI model to create the fine tunes.

This appears to be fairly effective, costing a small amount as compared with hiring individuals to generate the data.

The shortcomings of this is the fact OpenAI have prohibitive clauses in their ToS with regards to models trained with outputs from their models.

A potential solution would be to have an (_actually_) open initiative where we anyone can submit training data.

There are challenges such as moderation and QA.

But in general is it worth attempting? Am I mistaking something here? And is there some project currently running that does this that I am unaware of?
The difference is colour rendering and the nature of the spectrum.

An incandescent bulb is, by definition, emitting black body radiation - it’s a nice curve encompassing a good chunk of the spectrum, but as you say biased towards the red end.

LEDs tend to emit discrete quantised frequencies of light, as a result both of the dopants in the LEDs and the phosphors used on bulbs.

They have got better, due to better phosphors, but they still don’t render colour as well as incandescent bulbs.

That said, I’m all LED here as I cannot afford within our energy budget to burn a kilowatt or more on lighting.

I worked for a sister company. These features were A/B tested, their effect on bookings measured, and the numbers affected the bonuses of POs. They were thus incentivized to try these kinds of annoying tricks, because ultimately they work, or at least they do when their effect is observed only in terms of bookings.

I asked several times if we somehow measured customer retention, as we kept adding stuff I thought would have a negative effect in the long term (a customer would go through the whole booking process, only to never return because the experience was too bad.) We didn't. I guess it's difficult, I have no idea how this kind of metric would be computed.

The checkbox is a nice idea, it could help retain customers on the verge of leaving. It wouldn't work for customers who visit once and get so annoyed they never come back.

Also: a good portion of the traffic was affiliate traffic, like from Google Maps. I guess people booking from a Google Map listing care less since they land on the hotel page ? They won't be looking for hotels through the site UI, so they get fewer annoying pop-ups and messages.

Maybe? The idea that "more formal education is better" is kind of silly when you dig into it. What value does it give society to have a huge percentage of people spend some of their most important years learning things which are completely perpendicular to whatever career they might do?

Education at this point feels like exploitation. We tell people that they can achieve greatness, they just have to pay huge amounts to a college to be educated, when the truth is that most of the value of college is networking and status signalling, and the value of those is pretty much directly related to how prestigious the institution is.

Yes, we should set up a system that allows all people, whatever their background, to pursue a liberal arts education if they're passionate about it. But a system that makes a pretty useless and very expensive degree a barrier for entry for completely unrelated jobs is just exploitative.
I once was on am outdoors film set where we used 1.5 kW HMIs from Arri to light a night scene. One of the Arris was a bit beaten up and after a while we saw smoke rise from the lamp. Of course we shut the thing off and went to investigate.

Turns out the UV filter of the lamp had a slight gap on one side, a reasonably sized pile of insects had gathered there and started burning in the heat. It must have had something to do with the UV because they were really just gathering in that one spot and all other lamps were more or less insect-free.
So an ideal bug zapper would have a central light & the zappers coming "out" at 90 degree angle like rocket fins.

A lot of the rants came from frustrated people migrating away from Twitter by the shenanigans of Musk. There has been a bit of a culture change due to the large influx. But now that these people get to be comfortable in their new 'home', these discussion also become less frequent. Of course it is also who you follow that determines how you are exposed to these rants. If you are in a Twitter exodus group there'll be plenty more ranting.

I'd stumbled across the fact a few years ago that the oldest ocean crust on Earth is near this region: the Mediterranean, dating back roughly 340 million years.

Most sea floor is (geologically) quite young, as oceans are constantly recycled and re-formed. The Med though is the remnant of a much larger sea, dubbed the Tethys, shrinking as the African, European, and Asian land-masses converge, and ironically it's one of the smallest seafloors (and as others in this thread have noted, occasionally largely dry), that is also the oldest.

The other fact that stands out is that the oil-rich regions of Baku and Romainia (both important objectives during WWII) probably owe their existence to the Paratethys / Tethys seas.

But 84Wh is still enough energy to drive a modern battery-electric vehicle around 500 meters. Kind of puts things into perspective.

I find these numbers really fascinating because it shows how efficient battery-electric vehicles are, especially when you think about things like incandescent bulbs, which easily will run at 50W just to light up a small room.

Don't get me started on cars that display usage in kWh/h per 100km. Yes, you read that right.
You have a strange definition of “facts”.

Your first point, “America is a single market” is a fact, and a pretty uncontroversial one.

America being “geographically isolated from war” is conjecture. Whether Mexico will invade, or whether Pearl Harbor is part of your definition of “America” is irrelevant, it’s not a fact.

America “being able to produce everything” is not a fact and much too vague to ever be a fact. To begin with there are 20 mineral commodities that the US fully relies on imports to acquire. Could these be found in the US? We don’t know, and this is only one example, regardless it’s not a fact.

Americans being “ambitious to a fault” is not a fact, it’s your opinion and generalization based on the americans and non-americans you have met and interacted with.

A fact means something, it doesn’t mean “like an opinion but a really strongly held opinion”.
Great post! It really drives home the point that understanding the core concepts in calculus is way more important than just memorising formulas and mechanically applying them. The example problem shows how visualising and breaking down a seemingly complex integral can actually reveal its simpler underlying structure.
This reminds me of the need to be adaptable and versatile when tackling math problems, since relying solely on known techniques can limit your ability to solve more complex or unfamiliar problems.
Educators should help students focus on developing a deep understanding of math concepts and honing problem-solving skills, rather than just bogging them down in calculations.
This. The last decade has been absolutely devastating to the UK. We were actually getting somewhere before that - good investment in infrastructure, in education, long term thinking about all the things that require long term thinking. And then the Daily Mail oldies kick in with Brexit b/s, Truss, Sunak. And now we're a dysfunctional and mostly irrelevant backwater. Sad times.
Perhaps these are underlying reasons, but the fact is that >90% of kids want to behave. And that >90% of parents want their kids to behave. But teachers just aren't on the side of parents. Reactions of teachers to my kids were always somewhere between disappointing and infuriating.

Also, as a rule, teachers do not know their subject matter these days. Whilst I do remember their knowledge being less than perfect in the past, it was not like this. I understand teacher pay is a factor, but I refuse to believe these people have even the capability of educating kids.

Luckily good teaching materials are more accessible than ever as well, it's just ... all of them are outside of school.
