No music style appeared out of nowhere. So it will always be hard to pinpoint where things started. Maybe it is even impossible.

I always have a mixed feeling about music style classifications. It shifts focus from the music to discussions about what style a piece of music is.

Maybe techno originated from rhytmic tribe music. Who knows. Personally I don't care.

Lately I start to wonder if the symptoms of covid-19 are worse in areas with high air polution.

India is an example but in parts of the Netherlands where we have the worst air quality in Europe, we also see this.

It's hard to tell. But having a respiratory disease in an area of bad air quality won't help you.

It seems to be a mixture of clay, salt, rice fibers and lime.

So I guess the lime prevents erosion.

This is exactly the reason why I still have doubts about EVs (for now).

While hydrogen cars are less efficient I still think it will be a better option for the near future.

In a city like Stuttgart people have to park in double rows. Unless they can fully charge their EV in < 5 minutes those cars will never convert from combustion engines to a battery car. Hydrogen will solve this much faster than batteries.

Yes, but ACC does work well in a lot of cars.

Is this really the case? Maybe in the US, but here in the Netherlands people are not very positive about Tesla's self-driving capabilities. The main reason is that Teslas don't understand Dutch roads. Another is the list of broken promises made by Elon. But of course this can change in the future.

Right now Tesla is outperforming competition on three points:

  * 0-100km/h times
  * Range
  * Charging network

I believe most people don't care about the 0-100 speed. And most people can live with a little less range. So this leaves the network as a selling point. I believe it depends on the country how important this is. For example in the Netherlands you can cross the whole country on one charge. So you don't need a network.

Only recently competition is shifting focus to electric cars and more and more great EVs are being released. For example the new Hyundai Ioniq 5 is a car I personally would prefer over a Tesla.

So Tesla is doing great but I think they are becoming 'just another car brand'.

Haven't people been doing this in two lines already?

They are exactly like audio point samples.

Pixels are always interpolated, just like audio.

The fact that 1080 pixels exactly fit 1080 screen pixels don't give pixels a shape. And by the way, most modern display pixels are not squares. They come in all kinds of shapes. Triangles for example.

I once thought about building this, but it's much harder than you think.

The data has to be processed very quickly. I believe you should think in terms of 0.3m groove per second.

If you put a camera above the groove you also need something like a stepper motor to control the arm.

But I believe the biggest problem is dust. A needle will move small particles out of the way, but a camera does not.

This is also why laser turntables need 'clipping' filters. Dust will create all kinds of noise you don't want to hear.

In the Netherlands a lot of light polution is caused by greenhouses.

Now I am wondering: does something like a foil exists that keeps light in the greenhouse while letting sunlight pass through?

Ares is another gravity battery system. They run electric trains up a hill to store energy.

But looking at the size of the project, I have a hard time believing this is viable.

They can be.

For example you can lock them. This gives other opportunities than a tent.

They give better protection against the elements. So the body will have less stress giving the mind more focus on planning ahead.

Homeless people are in survival mode all the time. A tiny firm shelter can change that mode. This is also the reason why 'housing first' projects work. They take away the survival mode and make thinking about the future an option again.

Maybe it depends on the country. But after working with homeless people in the Netherlands I completely agree with you.

I helped homeless people who had a job but could not afford a house anymore for different reasons. Most were helped with housing after some time. But if that time is long the temptation to take more alcohol than you should is right around the corner.

As far as I know it does not detect DNA but RNA. RNA degrades slowly and it is estimated it can take 1 to 3 months to be completely gone.

True, but in most countries every year hospitals get overloaded around this time of year (2018 was also very bad world wide).

I believe testing works but only to see how many people came in contact with covid-19. It is not possible to tell how many people got sick from covid because the symptoms are the same.

I am not saying people don't get sick from covid. It's clear a new virus is going around the world. But it's a fact that we are unsure how many people really get sick from covid (alone).

And about the massive surge in India: my guess is that bad air quality in the big cities is not helping.

How I don't know. But it is estimated it can take 1 to 3 months before it is completely gone.

Aren't we too focused on PCR-test results? The article is talking about infections but most of the times this means positive results of PCR-tests.

A PCR-test only shows if you carry RNA of the virus. Not if you are sick of that virus, not if you are contagious.

The following scenario is true and happens often: Someone gets infected by Covid-19 but the body does break down the virus and the person does not get sick and was never contagious. A month later the same person is infected by the Rhino-virus and this time it is causing a cold. The person is tested and the PCR-test shows a positive result for covid-19. Which is true from a month earlier.

Since the article says that they estimate 50% of the population came in contact with the virus in Januari, it is to be expected that there are a lot positive tests. But the article is unclear about what this means for the healthcare system. Do a lot of people get sick, or is there just a lot of focus on positive tests?

As far as I know the only way to identify covid-19 with a PCR-test is a positive test and to know in wich order of symptoms occurred.

It's bad that this is happening, but from a developer standpoint it is also very easy to overlook things like this because most APIs are not aware of who the data is for.

When an API always returns the `last_seen` field regardless of who is querying the data, it's very easy to make the mistake to present the data to someone who should not see it.

That's also one of the reasons I think most CRUD APIs use bad practice because they always return all data on a READ and may always store all data on a CREATE or UPDATE.

But.. a company like Facebook should know better. It seems they just don't care.

While I agree Blazor is great, everytime I use it it feels unfinished.

For example binding select inputs to object is not possible while it has been working in other Javascript frameworks for years. Ofcourse you can use workarounds but it always feels like a step back.

And for some project that use custom auth it can be difficult to auth both Blazor and Controllers if you need some.

But overall it is a great experience. And I think frameworks like Blazor and Liveview are the future.

Yes, CoLD SToRAGE has a lot of nice links to tracks on his website: http://www.coldstorage.org.uk/

I believe the big difference is that the Carbon printers use a special bottom plate that lets air molecules passing through. That's why they can use chemical reactions to create better material properties. This also means the print doesn't stick to the bottom plate and they can print faster.
