- Comment on A new study found adaptive traffic signals powered by big data reduced peak-hour travel times by 11% in China’s 100 most congested cities – saving 31.73 million tonnes of CO₂ annually. 1 day ago:
Yes, if the induced demand results in similar levels of congestion - which it very often does - there would be more emissions in the end.
And you’re right, cars will exist for the forseeable future. I do not however want the government subsidizing car dependency since it is destructive to the environment and to everyone’s health and safety.
A couple of possibilities to drastically reduce traffic:
- turn all multi-lane streets within cities into single-lane streets for cars with exclusive bus and bike lanes to treat all forms of traffic equally
- reduce all speed limits to 30 km/h to reduce car noise, emissions and increase pedestrian safety
- traffic lights should prefer public transit, pedestrians and bicyclists instead of cars
- stop subsidizing parking spaces for cars with city money and drastically reduce on-street parking as cars take away massive amounts of space
- put toll roads onto highways as their cost is massively higher compared to fuel taxes. After all, trains have to pay a costly fee to use train tracks already - why should cars have this privilege?
There’s a lot more I could write here but you get the gist. Making car traffic more efficient does not reduce emissions in the long term in the slightest. Making car traffic less efficient reduces emissions instead because people will not use cars as frequently.
And keep in mind, I’m not talking about Bumfuck Nowhere (population: 725) when mentioning public transit. Cities have insane amounts of car traffic which can be massively reduced with just a couple of decisions. This would make car traffic less efficient as right now it enjoys many privileges over other forms of transportation.

And next year the congestion will be the same as before, except with even more cars and even more emissions.
This is equivalent to building another lane on a highway to increase throughput and decrease traffic jams. In the beginning, emissions will be reduced since traffic jams occur less frequently. And then, through induced demand, there’s congestion again.
Improving car throughput directly leads to increased emissions with a small delay.

Section 230 doesn’t apply to lemmy.world already because their instance is hosted in the EU and has to comply with laws that make them responsible for what’s posted already. Or rather, responsible if content isn’t removed quickly.
It’s also why comments supporting Luigi Mangione’s alleged murder are removed as they would make lemmy.world liable.

- Comment on How prevalent is the topic of mental health in America compared to Germany? 3 weeks ago:
not having enough therapists or having too many people who seek them
Neither actually. The health insurances are allowed to decide amongst themselves how many therapists are covered. And this number hasn’t been adjusted (much) since 1999 even though demand has skyrocketed since then.
Approximately 50% of therapists in Germany cannot accept public health insurance. Yet there is enough demand from the 10% of Germans with private health insurance ( + those who pay for therapy thenselves) to keep those therapists afloat.
In other words:
12.5% of Germans have been diagnosed with depression => 9.5 million people officially diagnosed which is certainly an underreported figure.
There are ~24,000 therapists in Germany.
As a result, there are 396 people with depression per therapist - meaning if every therapist worked 40 hours per week with 1 hour per client you’d have to wait 10 weeks between sessions.
Now add all other mental illnesses which would require therapy and you’d get an even larger number.
Sure, not everyone diagnosed with depression requires therapy. But this doesn’t excuse the obvious lack of paid therapists - which is openly acknowledged by the public health insurances but they are not legally required to change anything.

In my country (Germany)
Crossbows are legal to own and sell for adults. They are allowed to be shot at certified locations (i.e. shooting ranges) but not necessarily on your own property. You need a license for shooting them on your own property if the energy of the projectile exceeds 7.5 Joules. In comparison, a 9mm pistol shoots projectiles with 300-500 Joules.
Basically (for crossbows):
- 0 - 0.08 Joules: toy, freely available
- 0.08 - 0.5 Joules: toy, only available for children over 14
- 0.5 - 7.5 Joules: weapon, license free for adults, shooting on your own property is allowed
-
7.5 Joules: weapon, shooting on your own property is only permitted with a license
For comparison: a 9mm pistol shoots with 300-500 Joules.
Why would you want a crossbow though? Keep in mind that you are not allowed to use weapons for self-defense, even if you don’t need a license for them. Furthermore, I’m not sure whether you are allowed to publicly carry the crossbow at all.

Inspired, yes. But uber is still not a German word.
Imagine if I founded a company called “Tougt” and claimed this is an English word. Not inspired by, is. Who needs the letter ‘h’ anyways?
- Comment on Flohmarkt - a Fediverse replacement for Facebook Marketplace 3 weeks ago:
Removing the accent marks makes it such that the word isn’t German anymore, just German-inspired. It would have to be written “Ueber” instead.
You know, like a Mr. Böing founding the company Boeing.
- Comment on Flohmarkt - a Fediverse replacement for Facebook Marketplace 3 weeks ago:
Right, über is a word. “uber” is very much not. The points aren’t decoration or a pronunciation guide, they signify a different letter.
It’s like saying that Spanish people call their country Espana.
- Comment on What's the deal with male loneliness? 1 month ago:

I use public transit daily and hardly ever interact with anyone. Maybe there is one interaction every 100 days? I don’t frequently see two strangers interacting either, it’s unheard of except maybe for retirees with effectively infinite time.

There is significant proof of benefits:
Positive outcomes were decreased suicidality in adulthood, improved affect and psychological functioning, and improved social life. Adverse factors associated with use were changes in body composition, slow growth, decreased height velocity, decreased bone turnover, cost of drugs, and lack of insurance coverage.
I can’t vouch for the quality of this literature review (because I don’t care about taking an hour or more to read a paper for a Lemmy comment), but usually literarture reviews show a fuller picture than individual studies.
Also, this sentence is in the conclusion:
Although large long-term studies with diverse and multicultural populations have not been done, the evidence to date supports the finding of few serious adverse outcomes and several potential positive outcomes.
- Comment on Puberty blockers to be banned indefinitely for under-18s across UK 2 months ago:
Vaccines can have devastating permanent side effects. Should parents no longer vaccinate their children?
The answer for both is:
Whichever option does less harm should be taken. A delayed puberty, despite potential long-term risks does less harm than a trans child going through the “wrong” puberty.
Besides, due to the start of puberty having a pretty large range there should in theory be little harm until the age of 14 or so. And at that age children are much more capable of deciding on medical treatments than as preteens.

I’ve found a proper approximation after some time and some searching.
Since the binomial distribution has a very large n, we can use the central limit theorem and treat it as a normal distribution. The mean would be obviously 500 billion, the standard deviation is √(n * p * (1-p)) which results in 500,000.
You still cannot plug that into WA unfortunately so we have to use a workaround.
Since WA would calculate it through:
Φ(b) - Φ(a), with b = (510 billion - mean) / (standard deviation) = 20,000 and a = (490 billion - mean) / (standard deviation) = -20,000 and Φ(x) = 0.5 * (1 + erf(x/√2))
erf(x) is the error function which has one good property: erf(-x) = -erf(x)
Therefore:
Φ(20,000) - Φ(-20,000) = 0.5 * [ erf(20,000/√2) - erf(-20,000/√2) ] = erf(20,000/√2) ≈ erf(14,142)
WolframAlpha will unfortunately not calculate this either.
However, according to Wikipedia an approximation exists which shows that:
1 - erf(x) = [(1 - e^(-Ax))e^(-x²)] / (Bx√π)And apparently A = 1.98 and B = 1.135 give good approximations for all x≥0.
After failing to get a proper approximation from WA again and having to calculate every part by itself, the result is very roughly around 1 - 10^(-86,857,234).
So it is very safe to assume you will lose between 49% and 51% of your gut bacteria. For a more realistic 10 trillion you should replace a and b above with around ±63,200 but I don’t want to bother calculating the rest and having WolframAlpha tell me my intermediary steps are equal to zero.
- Comment on anyway, i started blastin' 3 months ago:
To expand a little:
For a much smaller sample size of just 1 million, the probability to lose just 1% is basically zero.
WolframAlpha doesn’t even bother to calculate the exact result and just rounds it:

- Comment on 7 years ago there were no billionaires worth more than $100 billion - today there are 18! 4 months ago:
That’s for the second one though, for the [verb] [noun] combination. The “[adjective]” [noun] combination implies spacefaring or similar, doesn’t it?
- Comment on 7 years ago there were no billionaires worth more than $100 billion - today there are 18! 4 months ago:
It’s not describing the noun, it’s part of the noun.
Quick analogy in German:
space billionaire = Weltraummilliärdär
spacefaring billionaire = weltraumreisender Milliärdär
In German, adjective + noun cannot be written together to form a new noun. To form one, only noun + noun can be used. And English is close enough to Germanic languages for that rule to remain the same, I think.
- Comment on 7 years ago there were no billionaires worth more than $100 billion - today there are 18! 4 months ago:
How is space an adjective in the first one? Shouldn’t it be a noun?
These Anglo-Saxons again, putting random spaces into compound words.
