dfgdghdf··on Israel may have achieved herd immunity against Covid-19
That's the plan yes, but unfortunately some schools have not been sent enough to deliver this.

Again, some schools are running this better than others.
dfgdghdf··on Israel may have achieved herd immunity against Covid-19
Different schools are running things differently. I am glad you used the tests, but they were strictly speaking optional. Lateral flow tests have a very high false negative rate, particularly when not administered by a trained professional.

I am not. This is first hand information for me. Nothing I have said contradicts your link either.

Depends if the lock-downs are at your doorstep or at the border. The UK had a few opportunities to pursue a zero covid strategy but squandered them all.

The mass testing story is not what you think it is. The tests are optional, self administered, self reported, only available to staff (not students) in many cases and have a 50% false negative rate.
dfgdghdf··on Cycling is more important than electric cars for reaching net-zero cities
They have been doing this in London. I think it makes a big difference! It also prevents people from parking in the bike lane.

Painted bike lanes do not feel safe enough to most potential cyclists so they don't lead to much modal shift.

We can't all drive though. There is not physically enough space in an urban environment. If you don't provide good alternatives - cycling is one, trains and buses are also key - then everyone will be stuck in traffic.

I listened to your source, but I'm afraid it wasn't very convincing.

The evidence they presented was an ambulance driver who had to go around a modal filter via side-streets to get to a patient who later died. We do not know if the patient died because of the LTN. I am aware of a case where Ealing council failed to delivery keys to an ambulance service - perhaps this was that? That error has now been rectified.

Needless to say, this is a tragedy. However, patients also die because emergency services get stuck in gridlock traffic. What needs to be show is that LTNs in general increase response times; but we were not presented with any data to support this. On the other side, there are examples of ambulances moving rapidly through LTNs, since they do not have to share the space with any other traffic. Remember, London's congestion is so bad that we have an air ambulance service. What we really need is data, and the limited amount we have so far is generally positive towards LTNs. One example we can look to is The Randstad, which is a huge urban area containing many connected LTNs, built from the 70s onwards. It doesn't seem to have problems with emergency service response times.

There's also the risk of missing the forest for the trees here. How many premature deaths occur from diseases of inactivity, toxic levels of air pollution and road accidents? Childhood obesity is around 20% in the UK and even higher in inner London boroughs. If you look at old photos of London, a striking difference to now is children playing safely on residential streets. Ambulance response times are not the only metric we need to keep an eye on.

The hosts like to make sweeping generalizations and talk about the "law of unintended consequences", but I wonder if they understand the law of induced demand?

True, but adults need around 30 mins exercise per day anyway so we can take the carbon budget from that.
dfgdghdf··on Cycling is more important than electric cars for reaching net-zero cities
It is very flat, but it's also quite wet and VERY windy. The Netherlands would not be the best place to cycle if it weren't for the infrastructure that they chose to build.
dfgdghdf··on Cycling is more important than electric cars for reaching net-zero cities
You are not alone. Transport for London found safety concerns as the biggest reason people do not cycle in London. Interestingly, many people who do cycle also considered it too dangerous.

For what it's worth, your risk from diseases of inactivity (diabetes, heart disease, etc) are far greater than the risk of cycling, even with poor infrastructure. Most people who take up cycling to work see an increase in life expectancy.

The solution is to separate cyclists from motor traffic on all major roads and introduce 30kmph limits on quiet roads. The Netherlands did this and has far lower accident rates, despite having more children and elderly people cycling. They don't wear helmets either!

* It's illegal in most countries

* It tends to be busy with pedestrians (not everywhere, as you mention)

* It's not safe when crossing side-roads

* It's inefficient if you walk at junctions

> Your commute is sufficiently short

Cities are usually quite small in area. USA is an exception to this but that is due to car dependency. We can't reverse care dependency if we continue to pander to it. In London, the average speed of traffic is much lower than a gentle cycle. For longer distances, municipalities should focus on rail infrastructure. You might also consider an e-bike, which can double or triple your range as a cyclist.

> You have facilities to shower and dress at work

Cycling at a moderate pace does not make you any sweatier than public transport . With adequate infrastructure, cycling in a city can be leisurely, rather than a battle against motor traffic. Riding a bike is not the same as racing a bike, much like how walking is not the same as running.

> You have sufficient time to shower and dress at work

Presumably you have to shower somewhere. What difference does it make if it is before or after your commute?

> You don't have to bring kids or sizable cargo

Cargo bikes are remarkably efficient and can carry two small children. They are cheaper than a car too. Older children can cycle. Did you know 75% of dutch teenagers cycle to school? However, we need infrastructure where people feel safe to do this. For occasional journeys a car may still be required, but that's fine, we are targeting the 90% case here.

> Weather is sufficiently good

Cycling away from traffic in the rain with fenders and a jacket is no worse than walking. Toughen up?

> You're sufficiently healthy

In The Netherlands, disabled and elderly people can use powered scooters and wheel chairs on the cycle paths. This gives them independence even after losing their driving license. In other countries, they would likely end up in a home. For those who must use a car, that is still an option. Traffic is actually reduced since cycle lanes have much greater carrying capacity in terms of _people_.

> My sister in particular is incensed about the road blocks put up all over London that have resulted in several local deaths as emergency vehicles can't get through to attend to heart attacks etc.

Source?

I'm guessing you are talking about LTNs (Low Traffic Neighbourhoods). For those outside the UK, these are schemes where through motor traffic is prevented from using residential roads. The idea has been around for decades, but they have seen a recent government push due to people switching away from public transport due to COVID. They are usually implemented by strategically placing modal filters (bollards, gates, enforcement cameras, etc). Emergency services are given keys to the gates and bollards. Walkers and cyclists can travel through unimpeded.

In a public Q&A, London Ambulance Service said they had no evidence of delays due to new LTNs. In fact, they are generally supportive of the schemes. By law, councils must consult with emergency services before implementation.

They have also been the subject of disinformation campaigns by right wing newspapers and taxi driver unions.

I don't approve of tax loopholes that large corporates abuse to pay an effective lower rate.

However, as an individual we can't change this. My (extremely cynical) advice is to hitch your wagon to theirs. Get some market exposure to these large companies and make their lobbying efforts work for you. It won't make society any more just, but at least you won't get left behind.

> What if it requires research and new types of engineering?

This is even more reason to do market research before sinking a bunch of cost into R&D!

The two cases where you can spend big on R&D without much in the way of market validation are:

1. The product is obviously useful, e.g. self-driving trucks

2. You are going for a patent / aqui-hire play

Point (1) is particularly dangerous when you get attached to your product idea.

Pretty sure Ethereum scaling as a currency is even worse that bitcoin.

Ethereum has some very interesting features, but performance is not one of them.

Good luck to them!

How does it work in terms of ownership? Can anyone buy a stake? Do you need to drive to earn shares? Can someone drive for a bit, then generate passive income from the shares? Will drivers get bought out by financial interests over time?

> For example, I believe the US government should offer people the cost to travel to any other country once.

Funny idea. An anarchist (left or right) would ask: why should I move? Why does the US government get priority here?

dfgdghdf··on Evolutionary biologist slays the beast of Individualism
Yeah, there's nuance here that so many miss. We can understand humans through a social lens when discussing psychology or anthropology. However, we might consider humans through another lens when discussing political theory. It would be entirely consistent to be an ardent individualist politically whilst also believing that humans are social animals who prefer close-knit units. I think the root of the problem is the naturalistic fallacy.
dfgdghdf··on Evolutionary biologist slays the beast of Individualism
I only got part way through the article because it makes grand claims, yet misunderstands Rand. Rand believed in individualist politics, and created these hero archetypes in her stories, but she also advocated for cooperation by free individuals. There's even a section in Atlas Shrugged where the protagonist tries to go it alone and finds it unfulfilling. Instead, the utopia in the book is one in which people voluntarily associate to form a society. The click-bait title doesn't help matters.
dfgdghdf··on Scala projects are difficult to maintain
But with the old GoF debates all of those patterns were built on a very small set of primitives. In fact, that's why the patterns were necessary! Scala combines (at least) 2 major paradigms into one language.
dfgdghdf··on Scala projects are difficult to maintain
Is the Scala language simply too big? I tried to learn it once (years ago) and quickly found myself overwhelmed by the number of concepts. I remember feeling like 80% of power of the language could have been achieved with 20% of the complexity. The latest Java releases are somewhat proving this with functional interfaces and records.
