Sweden’s death toll among the lowest in Europe during the corona year
"Most countries in Europe have been hit much harder by the pandemic than Sweden, according to a recent compilation of excess mortality. But in the Nordic countries, Sweden is by far the highest. The pattern is reminiscent of previous pandemics."

Based on research by historian Fredrik Charpentier Ljungqvist.
Solo, technical founder here. I started a very niche EdTech company 5 years ago, non-venture funded, grew it (code+users) while having reasonably demanding full-time jobs, and now operate it FT.

In short: it's tough; you're never off. Our errors either surface by way of user emails or monitoring (shoutout to BugSnag), and to this day I still have anxiety going places without my laptop for fear of a critical error coming up and not being able to fix it. I can recall running out of conference talks, being at shopping mall with my wife, and SO many other incidents where I'd hop onto the floor of a hallway, pull out my laptop, and frantically try to figure out what's wrong (and fix it).

On the support side, we have a small number of large clients. In this regard, there's no such thing as completely disconnecting. I have a shortlist where if I get an email from _____, it doesn't matter what I'm doing, I'm responding within an hour. Outsourcing to "watch the shop" is quite difficult; I find that some businesses can do this more easily than others. For something highly niche, it's more challenging.

On the tech side, I use managed services wherever possible. Heroku is wonderful (IMO), BugSnag is fantastic, we recently switched to Postmark which helped with deliverability of emails.

I've loved building this business. Control over my time each day is a reasonable trade for having to occasionally (rarely now) drop everything. At the same time, I miss big tech and the community of being at a larger company.

Hope that helps :)
Ask HN: How to Make Edutainment Videos?
I am looking to improve my videos to kids different aspects of programming. Some people I have shown the videos to have said they are pretty boring to watch.

Can someone suggest any resources on how to make educational videos more entertaining?

Thank you

I have a theory that one of the reasons why M1 isn't particularly well documented (if at all) is because Apple themselves are still getting to grips with it.

The main convenience of it is when deriving formulas, rather than when applying them. With all the constants set to 1, they don't need to be tracked throughout the formula, and can be put back in at the very end by looking at the units. Sprinkle the appropriate (hbar*c) or (mu0*epsilon0) at the end, and then you get your constants back.

Macbook Air M1 doesn't have sd card reader. To 'save space' and for better comfort I believe.

After a deep research I have found that Raspberry Pi manages to boot from such device.

If Apple engineers only knew about such amazing feature of micro sd card reader.

If they could just figure out how booting from micro-sd cards works they could do amazing things like booting Mac without a need for 'Another Mac' when recovery partition doesn't work!.

Somebody, please tell Apple about this possibility. It's amazing technology !
It also supports another common sense observation, which is that mixed-age schooling results in much better behavioral outcomes. Kids don’t obsess over their place in the artificial Lord of the Flies hierarchy when there are younger and older kids around to provide frequent role reversals.

> I have noticed my M1 Mac Mini behaves a bit strangely when I have my external USB3 HDD plugged in. The mouse motion is stuttery, but unplug the drive and it is smooth as silk. There's evidently something low-level going on, probably USB error recovery.

I've had similar sounding issues with a keyboard, mouse, a couple of USB audio devices plugged in via a hub to USB 3 (nothing high bitrate like a USB drive). I need to unplug one of the USB sound devices to stop this if it happens. I think all these devices are USB 2.0 at best.

I have written code in my dreams. When facing a particular problem if I think about it obsessively all day long I can sometimes end up dreaming about it. If the dream comes towards the morning I can often times remember the code I wrote and go try it out when I wake up. It doesn’t make for good sleep but the code usually works even if it has some really weird convoluted quirk that I end up working out once awake.

I had similar things happen in high school. For example the first time the teacher explained integrals I had a rough time visualizing the geometry. Having a dream a few nights later of an integral being like an apple peeled into a long strip helped me wake up with a better intuitive understanding of integrals.
I don't understand why this should be hidden.

Perhaps part of the answer is that if you're a solo founder who is staying solo, try not to create a business where you have these kinds of dynamics.

Seems like this is an extension of the Curry-Howard-Lambek isomorphism [1] relating type theory, logic and category theory together. I find that to be one of the most beautiful results in computer science and have been working on a practical language built on the same principles for a while (A mix of Haskell, Prolog and APL in a python-like language)

That would be true if someone refused to use any form of sandboxing, however there are multiple sandboxing solutions available that the "door" works in combination with. That is the only real way to make this kind of security work on an ordinary Linux distribution, the approach used by Android where a new user is created for each application is not really feasible.

There are also ways to sandbox X11, it's a bit harder to do, but you do have some options on how you'd like to do things.

If that were true, people would still be buying pet supplies from Pets.com and books from Amazon.com. The fact everyone knows what is meant by 'FAANG' should demonstrate how few actual niches exist in the digital space.

Communication is difficult when worldviews are very different and you seem uninterested in meeting me halfway. I'd be happy to explore this area of dialogue further, but you'd need to agree to stop insulting me.
People have this instict that "silence is consent".

Which makes sense in some circumstances. Like, when the whole group is paying attention to the same speaker, the speaker says something, there is an opportunity to object, and no one objects... you could conclude that either everyone agrees, or perhaps the speaker has so much social power that no one dares to object. -- So the idea is backed by either consent or power.

This doesn't work on internet, where millions of people keep saying millions of things, and there is simply no time to respond to all of that. So you see something that was said, publicly, and no one objected... but that doesn't imply consent nor power.

On the other hand, you can have an idea that 99% of people agree with, and the 1% would think twice to oppose it under their real name, but with anonymity someone is going to write "lol, if you think this you are a moron", and it's their comment that will likely remain unopposed. And one such person can make such comments on thousand places each day, if they are sufficiently obsessed with the topic.

Our instincts are built of some assumptions that no longer work on internet. One possible approach is to learn new skills. Another possibility would be to design online interaction so that it better matches our instincts. (For example, any comment would disappear after one day, or after it was seen by 50 people.) This could potentially be interesting, but there is little financial incentive to explore this, because companies optimise for advertisements and virality, not user experience.

>Human wants and needs are unlimited.

Before someone gets the funny idea that they aren't. It's literally government policy to hit at least 2% CPI inflation. CPI inflation measures the ratio between demand of consumer goods and services versus its supply. 2% inflation means there a tiny bit more demand for economic activity than can actually be supported by the economy.

This means there is an incentive for companies to grow and try to max out the production capacity of the entire country. This is especially important since production capacity cannot be saved in the literal sense. Money is just a piece of paper that says someone owes you a certain share of their production capacity. If you don't make sure the production capacity exists by the time you retire your money is worthless, which is why deflation is generally considered a death sentence for economies. Low demand causes companies to reduce their production capacity, which reduces employment and lowers demand in a vicious circle.

Demand side inflation through government stimulus can be effective way of accelerating the recovery of an economy with high underemployment. By doing pointless busy work like investing into better internet, upgrading the electric grid, building out renewables or even building public housing you can make sure that there is a baseline of employment. Since this work is funded through government debt it is increasing the supply of money. As I already have said. Inflation is what happens when you exceed the production capacity of your nation it tends to accelerate during full employment. Once there is enough work for everyone people get to choose their employers and they obviously pick the highest paying ones. Governments raise interest rates to make sure that only the most productive companies get funding. Inflation goes down and hits the 2% target again.

The big question is why does the central bank engage in ineffective policy? Why would it keep dropping interest rates when most corporations are already well funded and their biggest problem is that there isn't enough demand for their products? You need to give money to people but if they aren't credit worthy how isn't this just a central bank driven pump and dump since you're only giving money to those who don't need it?

If you really care about this you must also pay attention to funds you hold, as (AFAIK) the vast majority of providers earn extra yield by lending out their holdings

> BlackRock, Inc. (BLK) managing director for securities lending Jason Strofs indicates that this is a significant business: "about $3 trillion of our assets we consider lendable, which consists of iShares ETFs, mutual funds, collective trusts, and separate accounts," he says. "Across that $3 trillion, roughly 9% of those securities are out on loan on any given day."

SLB is a double-edged sword, for example since it increases float it may also work to reduce spread, reducing transaction costs for everyone
It seems unlikely that there will be any profound insights from category theory on how to write code, similarly to how thousands of years of advances in the theory of numbers have had notably few implications for how to count things.

Category theory is likely to contribute by giving specialists a language they can use to communicate, and it seems likely to me that at some point general tools rooted in category theory will have some sort of interesting implication for testing and debugging. Taking Haskell for example; the language isn't anything to write home about but the type checking in the tooling enabled a big improvement in writing bug free code.

So there is a probably a lot on offer for the sort of people who write tooling, and less on offer for everyone else.

CBDCs are not cryptocurrencies. Central banks are simply running their money transfer servers 24/7. It’s insane they haven’t done this before. Major economies will not offer central bank accounts to individuals because it would raise funding costs for banks. And the central bank doesn’t want to deal with customers directly.
If you are a solo SAAS operator and have enough customers to generate hundreds of support tickets in 5 minutes, maybe hiring more help several years ago would have been a good idea?

"Engineering challenges can be solved, but the real menace is an unwillingness, expressed through politics, to pay for the greenhouse reductions we say we want.

Power lines are unwelcome. Solar arrays and wind farms are not everybody’s idea of pretty and so must be located in unpopulated areas. Batteries can’t yet cure an intermittency problem, leaving only conventional plants. Coal is the worst of greenhouse offenders, gas is better and yet still opposed by greens, and forget about nuclear.

...

But I doubt many people will be phlegmatic when Texas-like rolling blackouts come to the Northeast or New England one of these winters, as they almost did in the 2014 polar vortex. Falling trees won’t be the culprit. The guilty party will be our choice not to invest in pipelines and backup gas plants to support our desired renewables in the face of cold spells a lot more predictable than those that landed on Texas.

This outcome is all but guaranteed unless we get a better discussion than the one we’re having. Then something else will become manifest: When the design performance limitations of utility systems come into play, it will always be in the interest of politicians and utility executives to change the subject to global warming."

I went to an optometrist and got a prescription. I actually went to two different optometrists and one of them misdiagnosed me. My prescription is extremely minimal, +1.25 on one eye and -1.25 on the other or something like that but it makes all the difference. If your eyes are extremely strained you may need to ask for the extremely strong eye relaxant drops when you visit your optometrist.. and warn him or her that you may have minus eyes. Apparently it's hard to properly diagnose minus eyes without doubling up on the eye drops.

> Wiles's proof of Fermat's Last Theorem is not an idea but it finished product

I don't think that distinction is the relevant one. The point is that it extended existing thought, rather than overturning it.

> If he told someone about the idea behind the proof in the initial phase without anything concrete and was not able to finish the proof, do you think the idea would be perceived?

I'm not sure what you're asking here. There's a reason mathematics journals are only interested in finished theorems rather than idle speculation, but I don't see how that's relevant.
> But as humans I don't think our brains are wired in a way to understand "there was nothing before something", we will always ask ourselves "what is the cause of that?".

Parmenides would like a word:

* https://en.wikipedia.org/wiki/Nothing_comes_from_nothing

One also has to ask "what keeps reality/realities existing?". Why doesn't everything simply just go poof into non-existence?

Aristotle (and Thomas Aquinas, in this Second Way):

* https://en.wikipedia.org/wiki/Five_Ways_(Aquinas)#Secunda_Vi...

argue that there must be an Uncaused Cause. Not a "cause" in the temporal sense of a first domino knocking over a second, third, etc, starting with the Big Bang; but rather like Yo-Yo Ma playing his cello causing music. What is the cello player of reality that is causing the reality that we perceive?

Whatever said entity is, it itself cannot be caused by something else, as you get into an infinite regress.
Apple has traditionally had really good boot options.

I've been able to put the OS on a usb stick and boot/run from that. Just hold down option at boot time, and select the drive you like from the list.

You could also boot from network boot volumes if they were properly set up.

I think you could probably boot from an SD card if you put it in a usb reader.

But the best - by far - is target disk mode. You boot mac #1 hold down the T key and it turns into a disk.

Then you can cable it to mac #2 and it will show up as a drive. Additionally you can hold down option on mac #2 and choose the disk from mac #1 as the boot drive, and then boot from it. This is really good when say #1 has no display or has a display problem.

I don't know how well this works with the new M1 macs, and also with T2 and/or encrypted partitions.

I was confused by GP until I reread it and realised that the operative word is how.

I don't know anything about Swiss law or Google internal policy but I think what he's saying is that it's illegal in Switzerland to dictate how your employees socialise with each other outside of work (and perhaps to dictate anything else about how employees behave in their private lives?), not that it's illegal for employees to socialise at all.

Plenty of older window managers don't support it correctly or use non-standard properties. Plenty of newer window managers have non-standard internal properties for unstable features too.

I would not say that Sway is doing anything special here, what they have done is exactly what I was saying earlier: placed the unstable private APIs in the Wayland protocol, with all the problems that entails. Applications should probably not be consuming those APIs directly, they will likely want to go through an abstraction layer.

I think the real disagreement here is about how to effectively socialize children, not about whether they can be socialized at all. Hyperbolic arguments aside, we can agree that humans can be socialized to behave as good members of a community, but humans who are not socialized will frequently behave like animals.
