>Of course, that flies in the face of all efforts to make things green…which involve better insulation, sealing windows against leaks, more air filtration systems and etc.

If anyone has a half-hour of time to waste, you can look into the science of "countercurrent heat exchangers".

It's fascinating to see how 2 pipes of air current switch temperatures when they're in contact and moving in opposite directions.

So if you want to be green AND have fresh air constantly circulating through a building, then forcing the warm inside air to pass by the cold outside air as they leave/enter the building can lead to somewhere around 95% energy recovery.

Add in a humidifier to the incoming air, and you'll have a comfortable room with humidity that will attach to airborne droplets, prevent evaporative release of a raw airborne virus, and help pull the droplet down to the ground via gravity.

That's true, that's outside of the expected range. But confusion of authority is the same principle at this level or at a higher one it doesn't really matter. This particular context has a low expected value but the same principle in another context can cost very large amounts of money.

Recently a big dutch retailer got caught out by a small thing, a suppliers administrative email got hacked and the company as a result wired a couple of million to the wrong recipient.

The real problem in this case is that Google has a perverse incentive to allow these ads-as-serps. Personally I think Google should be named as a co-conspirator in fraud cases like these. That would get them to clear this up pronto.
Oh that's right. I had a mostly fun time with google stadia. My internet latency is just good enough, even for shooters. Some days it was playable, others it wasn't.

They do focus on AAA games though, which I don't want to afford as a casual player. I like multiplayer with friends so we usually play not to pricy or free things.

The only "single player" I'm hoping for would be MS flight sim, but even there I'd just sing a few hours, not more.

To me it feels like I should invest in a good machine with a GPU another time because:

- streaming games is just not ripe enough

- I'll keep the machine for >5 years. Good to have one bottleneck less and such long usage is worth some investment.

---

edit: maybe I should look in to https://shadow.tech/

Doing some math:
5 years * 12 month * 12$ or subscription = 720$

If I'm generous and say my gpu only stays up to date 3 years: 430$

So I have 430$ at least to spare for a local GPU and for the first 3 years will have the better performance (lag, compression, internet-dependence) and for the last 2 years I can still think about renting for another 300$.

I'd say if I keep my current computer it's worth it, if I buy a new one anyways I should get one with a gpu.

uh oh, monthly pricing is 15eur
It's definitely a scam. They do not "provide a service", they mislead you into thinking you are dealing with a government office and that you are paying an official fee.

This is not "better advertising", it's just a scam.
> You're aware that we vaccinate children for a lot of things, right?

Yes. So they don't get sick, i.e. it's for their own benefit.
With a controlled ventilation system you have better indoor air than with leaky old houses and it's also more energy efficient.
Thank you, I'll have to check that out.
> We do not allow traffic controllers to work full 40h work weeks because the job is taxing.

I suspect the proper reason is because they might endanger others.

Outside of France, the law generally doesn't protect you too much from taxing yourself on the job.

Moderators should look for a different job, if they don't like it.

If they've been vaccinated and still insist on wearing the masks, I kinda think you're proving OP's point here. What do you even mean with "waiting for this to be over"? You're vaccinated, it's over, are you now waiting for a super-vaccine or something?

Mars is a single easily avertable project, still actually free for discussion unlike profit-motivated matters like the ongoing deforestation here. Until there's a clear profit to be made from Mars, it's politically possible to make a "ok, let's not" pact.

Why not make it more sufferable here on Earth first, build all sorts of guardrails on existence, e.g. modify biology such that we all have a certain maximum to which the pain knob can be turned. And only then terraform other planets? Why be premature?
We don't need to trust Facebook. You need to 'trust' individual employees to look for a better job, or not sign up in the first place.
We also vaccinate them so they don't infect people who can't be vaccinated.

I'm just trying it out and it seems not, iOS doesn't expose the photos folder to the app.

My workaround for this has been to install iCloud on a Windows machine which then downloads all the photos from my phone, and Syncthing on Windows monitors the iCloud folder and shares it with a Linux machine that does my backups. A bit convoluted but it works.

That's interesting actually : isn't that more a philosophical question or just an interpretation ? That is, if 1+1 is just an alternatative representation of '2', you can postulate that the universe is fixed, predefined and timeless. But if you consider that '1 + 1' is not just a representation of '2' but has more information in it, that information could be the dynamic and evolution that we call time. Isn't that linked also to the usual question of the link to reality of Mathematics ?
We're locking down because of a single cluster. Slightly more lenient than the first, but our government is probably just being a bit paranoid here. With the vaccines round the corner though, that's not necessarily a bad thing.

We gave Zulip (and Mattermost, Element/Matrix, Rocket Chat etc) a try when our company was looking for self hosted alternatives to Slack. Zulip seemed like technically the most polished product. Smooth and easy get-running experience (Element was the polar opposite). Lightweight UI that doesn't feel buggy. I'd have liked to see a bit bigger font but what ended up being the showstopper was that new users were very confused about how to write in a channel (or stream how they call it). Everything needs to be in a second level "topic". In pretty much every other chat app one can just select a channel on the left and get a text input field where you can write your message. In Zulip though you don't get the text input. You have to either create a completely new topic which new users really don't understand or click on any of the past messages in the stream to create a reply to that topic (but not that specific message). I suppose it works well after you understand the messaging model but it represents such a high initial point of friction that we had to give up on it. Non-technical users had a really hard time and the switch from Slack was not high enough on the priority list to push through with it.

tabbot: if you happen to see this, please please consider some kind of easy-mode which:

- by default always shows the text input no matter if you clicked on a stream or topic
- doesn't put the cursor in the "topic" input but the actual message input
- allows sending a message by pressing enter
- scrolls the window down when sending a message
- scrolls the window all the way down when clicking on a stream
- has a slightly bigger font size
- maybe also some simplification of the UI. You don't need the name of the stream above every message (see https://i.imgur.com/oeBY5yk.png )

I'm convinced with a bit of work to make it easier for new users you'll have a big boost in growth.

Back in January 2020 for every medical authority saying that the virus is airborne there was at least one saying: We expect this to be similar to a harsh flu season at worst, at best the virus will burn out locally.

It takes time for knowledge to get formulated, broadly accepted, and turn into actual policy. It has to be like that. Most of the time, being prepared but doing nothing is the best thing to.

SARS, H1N1, Ebola + probably many others all burned out before they reached the west.
Insolvency is different from illiquidity.
People can spend their entire lives studying one tiny aspect of our immune system; there are so many interacting, irreducibly complex systems that the average layman can be overwhelmed.

But there are simple things that can be explained visually. See, for instance, this video of Japanese scientists illuminating airborne droplets with green lasers: https://www.youtube.com/watch?v=hyZm6dx9Hss

Now, the contention here isn't that there are important concepts that should be explained to layman; the contention here is that there are important concepts that actual scientists need to explain to the decision-makers at the CDC.

If their own health wouldn't justify a vaccination, we should stop that. They can still consent to get vaccinated out of altruism when they're adult.
I missed the original thread but just had a quick read through now. That situation is absolutely bizarre to me. Don't people have regular 1:1s with their direct reports? How common is it for bosses not to meet regularly with direct reports?

WAT. If they have no moving parts, why even have a motor at all?

As other commenters have already said, terrible, terrible article. I expected more from IEEE.
I think it is important to emphasize that there is actually an important difference.

Union types don't allow to model GADTs, so they are less powerful than what some other languages offer. But on the other side, they allow for much easier composition. E.g.:

type Citrus = "Orange" | "Lemon"
type Prunus = "Plum" | "Apricot"

Now in typescript you can just do:

type Fruit = Citrus | Prunus

But in many other languages it's not so easy and you have to jump through hoops and e.g. either redefine the types and/or refactor the code (if you can even do that - if the code is from 3rd party libraries you are out of luck).
It’s just that most people don’t really care about wearing a mask in a supermarket and those that do don’t really get bothered with it when they refuse. But it does polarize society between people who love pointing their fingers at others who don’t adhere to their favorite mitigation strategy (‘they’re killing grandma’, ‘If only they had done X’). And of course masks are a pretty visible virtue signal.

People are a lot more critical about the other rules, the curfews, the ban on outdoor dining and bars and the closure of sports facilities. And the ‘you can’t have more than one person over’ rule is generally ignored.

By the way the official Dutch position still is that surface transmission is significant and one of the three ‘main rules’ is to wash your hands a lot.

Wasn't Singapore supposed to be one of the few success stories for eliminating Covid-19 without using vaccination, one of the countries that supposedly proved Western countries like the US could've avoided the need for economy-destroying lockdowns if only their governments were competent? Not to mention that they were and still are one of the most aggressive about mandating mask wearing, and were pointed to as a demonstration of how effective that was as well. The idea that Singapore going into lockdown proves the US CDC was wrong to advise vaccinated people don't need to wear masks seems extremely dubious.
The inner-west of Sydney is crazy for jet-wash effect. Something about the Sydney basin geography means that, when the conditions are right, you can get multiple minutes between a plane going over (at very low altitude) to the weird jet-wash paint smear of sonic cavitation ripping the sky apart.

It's awesome. Apparently there are quite a few calls to various bodies either complaining about or reporting unidentifiable noises in the sky.

It's pretty much the only positive of having a busy international airport so close to the centre of the city (obviously it's been a lot quiter over the last 14-15 months).
I got into clojure as a hobby for more than one year I am not an expert yet by any means.

It took me a long time to become productive in Clojure. There were simply too many things to learn at once, from syntax, to tools, to, more important, change of paradigm. I did the mistake to also learn Emacs at the same time (love it, but it just took too much time that I didn't have).

I know feel very productive because everything is done in the same way and those dozens of functions you mention is all I have to use 95% of the time. It takes time to learn them and even more to become proficient, but once you are there everything is very simple and fast.

There are two misconceptions that took me way too much time to realize:

- Macros are unfortunately needed sometimes, but they should be avoided as much as possible. DSLs are better done with data structures.
- REPL driven development is messy and stateful (you keep modifying vars all the time). A test driven development is much better. Having the REPL is still valid and all what you need most of the time for simple things, though.

Clojure can be very productive, but it requires significant (in my particular case, very significant) investment to get there. In the process, I learnt a lot about FP and, more importantly, about how to model almost anything as immutable data. Once this clicked on me, working in languages without this support for easy manipulation of immutable data structures looks like going backwards.
Not quite a pyramid scheme.

The basic scheme is:

* Issue crypto pegged to the dollar

* Hold interest-generating reserves

* Collect interest

I externalize risk, but it's a relatively low risk. That's different from a pyramid scheme.

Low risk isn't the same as unimportant risk. The whole point of crypto is to mitigate very similar sorts of systemic risks. Cash works pretty well most of the time.
As far as I know, Scandinavia was absolutely a farming society to the same extent England and France were. It's not like they all up and went a-viking: the people that did were a small percentage of the population, and this is to be viewed as equivalent as Rome sending the army (a small percentage of Rome's population) to conquer Gaul. They aren't suddenly considered less of a farming society when they do this. It's just how farming societies fight each other.
biggest issue in the UK unlike many other EU countries is how deeply polarized their media is. Very difficult to reason and bring the camps together which means the only way to get better is if it first gets worse. A complete shame considering the UK joined the EU because it was the sick man of Europe back in the 70ies and it was welcomed especially by other partners who felt it provided a much needed liberal balance to the power duality of France & Germany. We're all at a loss that they left IMO.

As for vindication the people certainly deserve not what's coming and happening to them, the true villains sit in the news rooms pumping out racist and dividing shit calling itself "free media" but the truth is it's run by a bunch of oligarchs. Eat the rich and bring guillotines to these places so that the poor and brainwashed people who've been fed on a steady diet of divisive garbage and are the real victims in this sham won't get hurt. It's a really easy trolley problem this one. Sadly history shows that the trolley company is the one that tends to win.
> was the gradual shift from very symbolic, human friendly (one might say 'elegant') mathematics into more brute force, pure crunching techniques.

Conversely, in these days when anyone can go buy themselves a couple of teraflops at the shop round the corner, when you look at the way they solved problems back in day it feels very strange.

But then, they didn't have a choice of course.

However, when you look at modern physics courses (worst offender IMO is standard quantum mechanics courses), where huge swaths of times are expanded trying to find closed form solutions to Schrödinger's equation, it feels very bizarre (and a giant waste of time).

Against what, a pandemic that's over by then? For more than a year, children's interests have been largely ignored, their well-being and education sacrificed for the sake of scared adults. Now we start vaccinating them, which doesn't actually benefit them but does benefit aforementioned adults, to protect them just in case they catch Covid after the pandemic is over, but not until they're old enough that this is actually a problem? Because they're suddenly that important to us? I don't buy it.
Give it time. Almost no one knows what Tether is. It's also a really technical, and thus niche, topic, not a lot of people understand the scam. Eventually a regulator body will finally do something about it.
I don't see anyone saying Scaleway so far. It's a cool, simple cloud. New services are showing up all the time, but it's still VERY simple compared to AWS or Azure. Also I find their pricing invoicing very clear.

New services are often free for testing, sometimes even afterwards (their S3 is still first 75GB free).

I love documentation and web UI of Digital Ocean, but find their pricing a bit to high for tiny projects. Linode is also amazing.

Exactly, this misconception is being repeated everywhere. It often goes up with inflation, not because of it. An asset with shrinking circulating supply will go up in price. It's self reinforcing because hoarding reduces the circulating supply. This is deflation and it's self reinforcing nature is why it is considered bad in economics.

This happens completely independently of USD inflation. If USD inflation goes up then Bitcoin may go up by the same amount. However, inflation may affect hoarding instincts in either direction, which can wipe out the influence of inflation on the price of Bitcoin.

For example, people may liquidate Bitcoin to buy commodities that are going up in price. The gasoline pipeline incident causes a shortage of gasoline, people start hoarding gasoline because it goes up much faster than the CPI average but Bitcoin itself can only protect against the CPI because Bitcoin holders want to buy things other than gasoline. If you are a consumer that needs nothing except gasoline then you would believe your Bitcoin are worth "CPI Bitcoin price" * (1+gasoline inflation rate). E.g. 25% gasoline inflation means it is worth 25% more than market rate, because you need 25% extra just to stay where you are.

The obvious problem is that there are some goods that went down in price. Assuming 20% deflation, someone else is willing to accept 20% dollars less for his Bitcoin. The average of both is 5%, therefore the "CPI Bitcoin price" would go up 5%. However, since the gasoline guy wants the 25% gains, it makes more sense to liquidate Bitcoin and buy gasoline directly but the deflation guy remains, which paradoxically drags the price of Bitcoin below inflation because it no longer tracks CPI but rather the CPI without the things that went up.
I had a similar experience with Zulip when I tried to set up a chat tool for our research group. I liked the ideas of topics and such, but other people weren't so enthusiastic to learn about a whole new chat paradigm. In the end we switched to Mattermost and we are quite happy with it.
A doctor friend of mine told me, at the start of the pandemic, that they found it important to correctly follow Public Health advice whether or not they (an expert) agreed with all of it.

The importance of following the principles for public health is greater than the importance of the advice being unbiasedly perfect at every moment.
What about uncomputable numbers like Chaitin's constant? Since we are subject to time, it makes it impossible to constrain its value on real line.

But in timeless universe, it should be a known final quantity, similar to 1+1, no? Because all possible halting Turing machines are in halted state there and non-halting ones can't exist there(*). So if we could peek into such universe we could sample them and get Chaitin's approximation with any accuracy desired.

(*) or, all their states exist and form a graph with closed loop, which would also be observable
I guess that's not including mortgage/rent, food, automobiles, etc. If that's the only source of income for the household and there are children involved it rapidly downgrades to sufficient but not wow, insane profit.

It's still an order of magnitude or two more than what other people in other parts of the world make, so the point about it being a sweet income remains valid but on a broader, societal level.

(Also, the health insurance is up in the "what? is that serious" league and the provisions for retirement and sick leave also too high to sound reasonable, but I won't question the OP's sincerity or financial choices.)
