271828182846··on A brief history of gasoline: Searching for the magic bullet
Interesting topic. I recently got my first own car (have been driving for almost two decades, though) and started to learn about how it works in some detail. Regarding gasoline - I just found out that my car (as most cars since the 2000s) works just fine with E10 (up to 10% bio ethanol). In Germany, though, this is still a heated subject due to intentional misinformation around 2010 by oil lobby and associates (ADAC first and foremost).

Here's what I learned about E10:

It's likely about as energetic as regular fuel (the chemical energy reasoning falls short due to side effects).

Its Octane Number is higher than regular fuel due to ethanol's Octane Number.

It burns cleaner (less coking) and also has a cleaning effect - again due to the higher ethanol content.

It's hydrophile qualities are actually an advantage as that means it binds water which is entering the system.

Some gas stations sell regular as E10 (and then cheaper) because it isn't economic or possible for them to have yet another type of fuel in reserve.

The reason why oil industry hates E10 is because it is more expensive for them while by law (in EU) they are forced to sell it cheaper.

---

There's only one catch which I still didn't wrap my head around.

My Mazda brings 160k kms to the table and features a "maintenance free" in-tank fuel filter which is somewhat difficult to replace. Now I'm a bit worried that using E10 will release built up residue attached to the tank and clog the fuel filter. And I don't know how fast this would take place.

That's neat that there is a term (and even a Wikipedia page) for that behavior.

I experience this always when taking LSD - especially during the come up.

271828182846··on Why does my diet soda taste off? Aspartame hydrolysis
I don't get the concept of diet soda. If you consume something unhealthy - shouldn't it at least taste good? Or is it some sort of self-punishment?

> I think this is an interesting perspective, it's very "American", it's like it has been accepted by these commenters that rampant thievery is a perfectly natural part of life and so, must be worked around rather than solved.

what do you mean? death penalty ... solved!

I intentionally keep the metal stripe unbent to create two air gaps to both sides of my nose for more comfortable breathing.

271828182846··on The Humble Brilliance of Italy's Moka Coffee Pot (2018)
interesting - is that a french press but with a smaller pored filter so you need more force and get more creamy consistency?

having said that the design is remarkably ugly. almost like some medical device - or maybe even like a bathmate? :D

271828182846··on The Humble Brilliance of Italy's Moka Coffee Pot (2018)
that's an interesting design. never seen that anywhere. do they hold the patent but fail to scale beyond italy? I find usual espresso machines to be too complicated and technical - also too expensive.

Well, as a German I feel obligated to recommend those officials to read up on Josef Mengele and then reconsider throwing that name around so casually.

they wouldn't gain leverage if their force just wasn't that great and it all would be just a bluff. I mean, if someone on HN knows that the US government would know that, too. I think what they demonstrate is unpredictability and trigger happiness. people keep their hands of others if they might go off easily.
271828182846··on Firefox 94 has No Visible Border on unfocused tabs
I really like Firefox. But this Tab design decision is smelling like function follows form instead of the other way around. Seems to be the Zeitgeist that utilities are designed to look good instead of being as useful as possible.
271828182846··on The great executive-employee disconnect
It also seems to me that many of those who advertise for coming back to the office have a family at home and are fed up with being around them all day long. Let's be honest - most men are bored and annoyed by their wives and children. It's much more pleasant to feel im important at work, get raises and have maybe an affair or two going on.

(having an "own" family somewhat correlates with seniority and career level)

271828182846··on The great executive-employee disconnect
yes ... being a boss is for most bosses about being and feeling important. and you can only feel that in personal contact. also employees are less impressed by higher ups when they can hide behind a screen.

271828182846··on Life Improvements Since the 1990s
( "Not Rewinding VHS tapes before returning to the library or Blockbuster" ... how about going to some video store was kinda cool and added some social aspect to sitting on your couch alone and watching a movie? how can you even add crap like that on such a list with such a title and not realize how delusional this is?)

there are no material life improvements - only more efficient dopamine triggers. but that's not an improvement because before the 90s - guess what - they had their own triggers.

in that spirit you could add how access to more diverse pornography brought happiness to so many lonely men considering how especially a hundred years ago they were so starved they would get aroused at the sight of women's knees. poor bastards.

guess what, your mega-tittie-porn isn't really an improvement over some picture where a woman lifts her skirt you can see her ankles. it's just a fucking going round in circles what you all confuse with "improvement".

life for many people fucking sucks and most of those "improvements" only come at the expense of removing people further from any kind of meaningful spiritual fullfilment.

271828182846··on Activision Blizzard Sued Over ‘Frat Boy’ Culture, Harassment
how about reading the article?

"The suit also points to a female Activision employee who took her own life while on a company trip with her male supervisor. The employee had been subjected to intense sexual harassment prior to her death, including having nude photos passed around at a company holiday party, the complaint says."

those photos and them being passed around is a pretty substantial allegation.

271828182846··on Activision Blizzard Sued Over ‘Frat Boy’ Culture, Harassment
Maybe you should mention that your explanation refers to women ... I mean some men do enjoy harrassing women and those come and stay there maybe particularly for that specific reason.
271828182846··on Germany's national healthcare system adopts Matrix for communication
In some regions "[arsch] eng" might well be used ... funny thing is it means more or less the same as "ass tight" but [arsch] would be dialect for "arg" which can be roughly translated to "almost a bit too much".
271828182846··on Covid-19: India excess deaths cross four million, says study
Regular mortality in India is about 7.5 per 1000 inhabitants. That's about 9.8 million deaths per year in India.

Population of India is about 1.3 billion.

Just to bring numbers into perspective.

It actually just shows that Covid is far from as dangerous as it is made out to be.

Many people in India live under 3rd world conditions in extremely crowded slums and towns. They have barely any medical infrastructure. The air quality in the bigger towns is abysmal.

If the exponential growths panic would be justified we'd have to see a way higher excess morbidity!

The truth is there is no exponential growth in reality because any growth hits an upper limit at some point. The western media wants to make us believe that no such upper limit exists or is so high that we can just assume exp growth. In fact all countries show dynamics indicating a rather low upper limit at which point growth ceases to be exponential and instead starts to either stagnate or decrease.
