wohlergehen··on We need to tell people ChatGPT will lie to them, not debate linguistics
To clear this up, because open Holocaust denial is never OK:

Thousands of jews were indeed murdered at Babi Yar, you can find their names online [0]. Paul Blobel [1] was executed at Nuremberg for this. No serious source disputes the killing of jews at Babi Yar, be it the US, Germany (where this matter went to court), Israel, Ukraine, or Russia.

wohlergehen··on Sweden has invented a word to encourage people not to fly
> It is not exactly clear whether passenger flights are less environmentally friendly than various other options. Driving for long distances can be worse for the environment than flying commercially[0].

There might be some question whether cars less efficient than planes, but I am not aware of any such doubt w.r.t. trains, which is what we are discussing here. Also note that few people would drive the long distances that a plane or train enable them to cover.

> but it is unclear how the method of calculation (ecopassenger.org) works, whether it considers that rail and road infrastructure requires far more energy

The methodology is available [0]. It considers direct emissions, so no maintenance or manufacture. Can you make an argument why these should be more than a low percentage of the direct emission? I mean sure, it might require 1000x more energy to maintain, but its not like that is a large part of the final emission per kilometer.

> since you cannot change the load of plane and train separately

Why would you need to? Of course people who take the train instead of the plane reduce demand for planes and increase demand for trains. So there are fewer plane trips and more rail trips. Assuming that rail trips are environmentally advantages, why would that be a bad idea?

> even though it is clear that flight operators often overbook planes, while trains often run with pretty low loads.

The model considers rail load factors based on real world data where available, substituting 35% as an approximation where no data is available. Do you have any reason to object to that?

wohlergehen··on Ask HN: What can be done to prevent a climate catastrophe?
At least in Germany, this exists [1]. Sorry, but the page is not in English. They target fossil energy, chemical and arms manufacturing industry mostly. You should check if this exists in your country (I can't believe it doesn't) and get involved. This approach does work.

wohlergehen··on After Five Years of Living in Trees, a Protest Community Is Being Evicted
The movement around the Hambach forest is incredibly diverse: it covers die-hard anarchists, protestant and catholic priests and everything in between. There is no need to not partake in a protest just because you suspect you might not do everything you can to further the cause. Any support is usually welcome.
wohlergehen··on After Five Years of Living in Trees, a Protest Community Is Being Evicted
I live about 50 minutes away from this location. In my opinion it is an absolute atrocity, especially given the recent tragic death. Our politicians are discussing about phasing out coal until December (there is a commission to find suggestions), and despite this, RWE (the owner of the mine) tries to evict the occupation. It is a pure provocation since it is absolutely unclear whether clearing the forest is ultimately necessary.
wohlergehen··on Discovery of Galileo’s lost letter shows he edited his ideas to fool Inquisition
I am very sorry, but not mention or discussion of Galileo on this site is complete without a mention of the great ptolemaic smackdown [1]. If you have about 4 hours worth of your time (even in installments) it is deeply recommended.

wohlergehen··on Modeled impact of large-scale wind and solar farms in the Sahara
In the same sense as your server has an "energy consumption" of 2000W, i.e. 1W <=> 356*24/1000 kWh/a.
wohlergehen··on Emirates Planes Could Be Going Windowless
IIRC it is mostly so that the passenger's eyes adapt to the outside light level in case of an evacuation.
wohlergehen··on Show HN: Blasjs – Pure Javascript implementation of BLAS
I would be curious if you've done any benchmarks. It would be interesting to know how close this gets to a "naive" and "expert" regular L3 BLAS.

If you want just the aesthetics, add just the tiniest bit of turmeric. It dyes like crazy and if you add little it adds nearly no taste.

wohlergehen··on Hosting Jupyter Notebooks for 100k Users [video]
Native Jupyter has the magic %%bash command, so a lot of this should just be possible, i.e. you start a cell with that, and it will invoke bash to execute it.

More generally, there is %%script <x>, which executes the cell using <x>.

It looks really cool, much more usable (IMO) than Inform7, which probably is the grandfather of all CYOA languages.
wohlergehen··on 'We're doomed': Mayer Hillman on the climate reality no one else dare mention
While population development historically is exponential, looking at current societies all over the world indicate that there are ways to significantly reduce the growth: economic development, women's rights and education.

In particular, population growth slows down where it matters, i.e. for those people that have the biggest carbon footprint.

wohlergehen··on EU copyright proposal could undermine the use of Creative Commons licenses
Agreed. In the past, media companies that tried to enforce a "link tax" (IIRC in Spain and Germany) were just unlisted from the news feed---and lost a lot of traffic, rendering the whole endeavor moot.

I guess they think that if everyone has to enforce the tax, they are protected from the threat of being unlisted.

AFAIK the official website is taler.net.

The bad english and the new domain suggest that one should be carefull for some more official confirmation.

EDIT: I reached someone from the project on IRC. This is a know scam.

Agreed, a "progressive" pricing based on salary would be a good way to address this, e.g. >50k -> 1%, >80k -> 3%, >100k -> 5%, >120k -> 7%.

wohlergehen··on Cloud companies consider Intel rivals after security flaws found
Section 6.4 of the Meltdown paper seems to indicate that the same flaw is present in AMD CPUs, but not easily exploitable.

Do you have a different source for that?

wohlergehen··on Game Engine Architecture Lectures
<Space> navigates through them linearly. The arrow keys navigate (in a way) through the "sections".
wohlergehen··on Power Prices Go Negative in Germany
1) Related to how the EEG is more a subsidy of energy-intense industry rather than regenerative energy, at the expense of the consumer.

2) "Die meisten Stromanbieter halten an ihren aktuellen Preisen fest, und 78 Versorger senken ihre Preise sogar im Schnitt um 2,2 Prozent. Zugleich aber heben 64 Versorger ihre Grundtarife im Schnitt um knapp drei Prozent an" --> Most utilities keep their prices fixed, 78 reduce prices by ~2.2%, 64 increase by ~3%.

3) More than France (nuclear), Spain (nuclear, wind), Sweden (nuclear, hydro) and Norway (hydro). It is unsurprising that countries heavily invested in nuclear and hydro produce less CO2.

Germany's energy policy is far from perfect, but probably one of the most future-proof in Europe (which costs money). France will have huge issues with decommissioning in the next decade; nuclear is not a silver bullet.

wohlergehen··on Don't Assume Your Data Scientist Is a Software Engineer. A Thread:
I agree that there is a big issue in the field w.r.t. "unknown unknowns", where more effort needs to be put into making useful knowledge available. However, I do not think that many of these technologies are hard for someone who understands data science, at least at the level neccessary to use them. Doing productive developement in these more systems or CS focused topics is a wholly different topic though...

I know I've come across a debugging story that ultimately ended up with the author loading binary data into audacity and hearing/seeing a pattern.

Does anyone know what I mean, and has a link, since I can't seem to find it...?

wohlergehen··on USPS ‘Informed Delivery’ Is Stalker’s Dream
This actually how it works in Germany. The postal service provides PostIdent [1]. E.g. when opening a bank account, you get a letter with which you go to a post office where you sign and your ID gets checked.

wohlergehen··on Blueborne – A new attack vector endangering major operating systems
Well, I've been meaning to root mine and flash crDroid... This is certainly the final push.

They state 10% of all Android devices are vulnerable and won't get patches, and since the vulnearbility is arguably wormable I can't see how these devices will stay clean.
