> the benefit of immutability isn't what's happening in your own local scope, since it's typically quite easy to track what your immediate context is doing to a variable.

From my experience any sufficiently badly written code is hard to understand even in the local scope. The bar for hard to understand code isn't that high because the complexity of well written code is very close to zero.

Most code that avoids reassignment can be read from top to bottom. Code with local mutation can require backtracking and then the complexity can start exploding but that doesn't necessarily apply to code with mutation across functions. A simple list.add() doesn't cause anyone's brain to melt.

A classic is that someone writes a for loop like this: for(;i < 10; i++). You now need to go back and check what the start value of i is even though 99% of the time it is 0. Then you need to check if the counter is used for anything after the loop has exited because sometimes a loop is just trying to find the first element that matches a predicate. Now imagine if the i variable gets reused by a second loop. You now must check if the i variable is resuming the loop at the same position by backtracking. Every single line of code has the potential to amplify the complexity of the entire function.

All that meaningless complexity has no reason to exist. It doesn't provide any value and it doesn't cost anything to avoid it.
I thought similar. Four developers/full-stack, but then a customer support function that'd roughly 0.X scale with users, then marketing - could double-hat that, then certainly a legal/compliance team after some scale, also finance which probably doesn't need to scale linearly but should be a couple of people at least and no double-hatting on these at their size. So, thinking a bit, perhaps more than four.
> What really surprised me was the core principle at British unversities - "don't assume prior knowledge of anything".

The rationale is that you want to give 18 year olds the opportunity to pick a field of study that they're excited about now rather than forcing them to choose something based on what kind of education their parents thought proper for them six years ago. If a single "intro to programming" course and a slightly easier first math course can onboard smart students who otherwise would be hopelessly lost, and the only downside is that a couple of better-prepared students feel a bit bored, that's a small price to pay.
Just bought it and it looks great! One feature that Slack's video call has that would be nice to add is to have the possibility to auto-fade what you've drawn. Lets say if you haven't drawn something within 5 sec, what you've drawn slowly fades away.

Yeah, didn't know how to best translate "tocilar" into English, I guess it's a combination between geek and nerd? Couldn't tell.

> an unstylish, unattractive, or socially inept person

I was definitely unstylish, that's for sure, and I was no Adonis, that was also certain, but the good thing is that back in the day that didn't matter, how you looked and dressed as a kid didn't matter. I only had 2 pairs of jeans for my 4 years of high-school because that was all my parents could afford to buy me back then, but to be honest I wasn't aware of that back then. I'm afraid nowadays things are completely opposite.
I'm not sure what you mean by "never took it as a subject". In the UK you study Biologly, Chemistry and Physics up to and including year 11 (16 years old). I don't believe you can opt out of those, along with English and Mathematics.
I wouldn't be surprised, however, to hear that what we did learn in those years was behind a lot of Europe/USA.

That is what I am noticing with my son's maths lessons. He is in year 5 at a British curriculum international school. The word problems seem a bit too easy, in my opinion.
As an artist I battle with this everyday, curious people actively seeking for new music are really hard to find
"The Rite" may have been technically groundbreaking, but it sounds TERRIBLE. We've seen plenty of artistic experimentation over the centuries leading to new artistic genres, but early experiments like these are almost always awful. It takes someone with skill in aesthetics to turn the new into the beautiful, and it's rarely the inventor who does this.
I thought it would be an issue as well at first, but it has really rarely been an issue.

The performance degradation might not be even, but generally it approximates pretty well a slower system, without having to use a slower system in my experience. You can deal with the few edge cases individually.

If you really care about performance on slower computers, then at some point you'll need to use one for real.
But at least this way you have a fast feedback loop.
The system was absolutely flawed, still is, but still good enough to encourage the highly skilled.

Our (Romania's) education system was (is) the same, if you were GOOD at something there were plenty of paths that teachers would generally push you towards, special clubs for maths, languages, art (less common). Or schools who would try to group together highly skilled students.

System (after communism) has the same flaw, most rural areas have worse access to education, or better said, much worse quality of education.
The teachers too. We had one that could work out trig stuff in her head to a fair amount of decimals.
Interesting I see the other version has WiFi. Kind of curious if these become ubiquitous enough just having one would make you seem like "a bad person".

I suppose most people probably wouldn't know what this is.

Anyway looks really cool

When you're in such a school you can really feel what's up, especially in Soviet/post-Soviet case: the socioeconomical situation is exactly the same (because communism), and you usually know the families of other pupils. Then you see the ones who try hard but still can't get it, you also see the lazy smarts.
You don't get to choose different maths A-levels in Russia. There is one state standard that every school and every student has to stick to. You can have accelerated or deeper "special schools" but you can't evade the state standard on maths or you won't get you high school diploma.
As an aside, I've worked at Flora Holland, the company (a cooperative owned by a hundred and then some growers) that orchestrates a lot of the logistics; the clip in the article with the carts is a small part of their transit halls. They start in the early morning with the flowers and plants coming out of cold storage and auction them off early on; before midday, the halls are quiet and empty again, hundreds if not thousands of trucks full of carts and containers having been filled and sent off by then. Each and every day.

Besides the actual shipping of plants etc, one of their major logistical challenges is managing the hundreds of thousands of iron carts (pallet sized) and millions of plastic containers (where they put the actual flowers in), those all have codes and deposits to manage, and every day they have to calculate how many they need. (same with how many temps they need, they can vary the amount of people they employ by hundreds if not thousands per day. Highest amounts are around valentine's day and mother's day).

Software-wise it's also interesting. I can't mention much about their current day development, but one factoid is for example the auction hall itself. It's a Dutch auction (see wikipedia), so response times is crucial. It turns out that the exact position you're sitting in that hall already has an effect on the response time and whether you win or lose an auction. They tried to put it on the internet as well so the buyers could do it from home, but they couldn't solve the latency problem (at least not to the satisfaction of the buyers).

Nowadays though, less and less is sold via the auction, and less and less actually passes through the main venue; there's a lot more orders in advance (like shops ordering roses a year in advance for valentine's day), and there's a lot more direct grower-to-customer traffic.
I'm not sure this is specific to any particular school of mathematical education. There is bound to come a point at which you cannot understand everything and have to start winging it. If you can cope with that, that's good, you are prepared psychologically for research mathematics. And just having learned the patterns will hold you in good stead. But if (as I did) you find the whole thing an insult to your pride then you are only preparing yourself for failure.
For your European customers you should likely make it more clear what stripe.js does before urging them to install it on every page of their website. Using it as soon as a user has a probable interest to purchase a product (e.g. when he/she clicks on “Register” and chooses a plan) would very likely be acceptable as a legitimate interest under GDPR, tracking all users even if they don’t have a clear intent of purchasing something and e.g. only want to get information about the product will definitely not be acceptable as a legitimate interest and would therefore require clear consent first.

A carrot you eat and turn to literal shit.

Flowers like you say lasts a week for multiple people. Also unlike kitschy stuff you buy and just sits there forgotten, you appreciate them, you have to somewhat care for them, they add value to life.

To say they are "they are not essential" is saying life itself is not essential, just eat powder and sit in a room if this is the case.

I feel like what you are saying is you don't like flowers so no one else should.

And I really think it's callous for us to forget the "More than 150,000 people now toil on Kenyan flower farms, many of them women." These are the poorest of the poor, to take away what little they have is pretty thoughtless.
Thanks for letting us know. Weird. Just tested and it worked here. We just scaled up more resources, so maybe it should be better now if you hot reload. Are you logged in? :)
For a while my company was considering docker precisely to keep an old python app (described as python 1.5) running. The dependencies of that app haven't been maintained in a decade, will never be upgraded and will likely disappear soon as the hosts remove their mercurial repos. Having the base machine running something modern with the old python stuff in a docker image seemed like a promising solution but the stuck with RHEL7 instead.

Thankfully it's no longer my problem.
Yes, it is doable. Not sure if Apple has some policies restricting that. If not, then it is definitely doable.

May I ask why would one need a non-app store version? I thought users would trust the App Store more than other websites like gumroad, paddle, etc.
My (slightly more recent) US high school experience had nearly all students cover the calculus you described by the end of high school, and about 1/5 of the students got fast-tracked to the point that they studied linear algebra and multivariable calc by the end of high school.

I talked to a couple of friends about this, and about 1/2 had similar course offerings.

If a person is horrified by the idea that some children are superior learners due to genetics and yet this person sees their attempts to develop inferior learners fail, their only option to achieve equality is then to socially engineer the superior learners downwards to match their political viewpoint. And it's also great business in a deindustrialised nation to milk gullible students for tens of thousands of pounds every year to generate revenue for universities, landlords, drinking establishments, etc, in exchange for a not particularly useful piece of paper at the end.

Ask HN: Co-founders can't be convinced that we need investment
Our start-up has changed direction three times, but after more than 24 months we still do not have a saleable product or even a working prototype. Despite this situation, I can't convince my co-founders that we need external investment to shorten the time to market. Instead, they are only interested in government programs with lengthy application procedures or simply in making do with subpar equipment and tools, which also means that we constantly fail to meet deadlines. Besides, we are working without a salary, which I do not think is acceptable anymore, how should I proceed?

I always thought organized crime works in such a way that, at any given layer, a person could only provide evidence of criminal activity of their peers at the same layer, and maybe a bit of dirt on their bosses a layer above - but they couldn't bring enough legally admissible evidence to impact the higher layers. So if a random bottom-tier gangster starts to testify, everyone above them on the ladder just denies knowing them (and each other). The legal system can't proceed, and meanwhile someone from the gangster's family suffers a fatal "accident".

There are only two ways of realistically demonstrating encoding artifacts: decode the actual format client side or transmit a lossless encoding.

Do you have a powermeter on your CF bike? If not get one. Apart from being the ultimate training aid, you might find your gf is putting out more watts than bike's manual claims it is. Clipless pedals may help as well allowing faster acceleration by putting more power into the initial pedal stroke.

I would say the average commuter can put out 300w for 10 seconds. They would hate it but everytime you see a commuter straining up a hill, they are putting that kind of wattage. In practice they probably don't because they don't like the strain.

Odd if you're looking for the simplest way to prove that. Less odd, perhaps, if you're looking for something that can be proved simply using induction, in order to make students do their first proof by induction.

I don't remember precisely what it was we were asked to prove. It may have been the converse.
I find the article strangely void of content. If we are investigating funding of discoveries to find a formula to repeat, it seems to me the way to go is, to find the most relevant discoveries and see who funded them.

In the UK and probably the rest of Europe you can still buy borosilicate Pyrex made in France, but this single decision destroyed any trust I had in the brand. It's not even a new decision[0] and I am mostly unaffected by it but any discussion about Pyrex in person will invariably lead to me butting in with an emphasis on borosilicate making the glass temperature resistant and not the brand, it shouldn't even be necessary but occasionally import Pyrex makes its way onto places like Amazon.

This is one school of education. The other is the Finnish model, with no separation. I am yet to see some comprehensive multinational study that would suggest which is better. (Better for the students, or society as a whole?) It’s probably impossible to do objectively. I also feel there is probably quite a difference between these two systems in the effects on the, say, top 0.2%, 2%, and 20% of the students.

We have lots of Soviet teachers in Israel, they always said "it's better to solve something in 15 ways than solve 15 things the same way" and that resonated.

To be fair though, that approach is omnipresent in the math faculty in the Hebrew University - so it was not unique to the Soviet paradigm but it was interesting to see it in High School.

There is also a genuine sense of "let's try to do this!" that's very common in computer science but is more common in "soviet" math than "regular Israeli" math.

The most important distinction IMO was that these teachers were not _afraid_ of Math and could discuss higher level non-high-school concepts typically. Having a teacher that loves the subject is important.
(Author here) Even as a statistician, I can never remember which way round sensitivity and specificity are, and with the current situation, the public are being faced with terms like false-positive, predicitive value and prevalence more than before.

For my own amusement, I wrote a little game to allow people to encounter these concepts hopefully intuitively. The settings have all been set at unrealistic levels to make the game varied, and some of the wording might be a bit trite/patronising, but I'd really value any feedback. As with most biostatisticians right now, time for side-projects has all but vanished, but if there are things I could do to make it more useful it'd be great to hear.
This is one of the more famous results in political science: Duverger's Law. It's normally phrased as "in a first past the post system, the number of effective parties tends towards two".

It's... a useful model. It turns out not to work in practice everywhere, though, as there are complicating features with geography and ideology that tend to add parties. Canada, for example, has 2 and a half effective parties (Liberal, Conservative, NDP) in general, and more in Québec. The UK also has two and a half (Con, Lab, Lib Dem) plus powerful Scottish and Welsh nationalist parties, plus an entirely different party system in Northern Ireland. So 'tends towards' is going a lot of work.
