markvdb··on Jeff Bezos killed Washington Post endorsement of Kamala Harris
That is possible if their editorial staff honestly believe two things:

- The rule of law and the republic as a process are superior to anything else.

- One of the candidates does not subscribe to these sufficiently.

In that case, and given the political duopoly, they could still claim to be impartial towards candidates. Their only allegiance/partiality would lie with the rule of law and the republic as a process.

At least part of that might very well be illegal.
markvdb··on The Nazi of Oak Park
> The craziest detail about this story is that, in the early 1980s, there was an organized effort to pressure the White House and pass legislation to make it impossible to deport Nazis. The effort was led by a group of Baltic and Eastern European ethnic affinity groups, largely out of Chicago. They were called "Americans For Due Process", and their ambition was to pass legislation requiring something like an international Nuremberg Tribunal process in order to anyone deported.

Some Baltic emigres to the west were clearly guilty to crimes against humanity. https://en.wikipedia.org/wiki/Viktors_Ar%C4%81js comes to mind.

I do not share your surprise about the pressure on the White House though. This gets easier to understand through a personal histories lens. Imagine you were a young male adult Latvian in 1940:

- 1940: native country annexed by the USSR. Most upper class deported to Siberia.

- 1941: native country occupied by Nazi Germany.

- 1942: forcibly conscripted into the Latvian Legion of the Waffen SS

- 1944-1945: native country occupied by the USSR again. escape to western Europe.

- 1946-1950: native country still occupied, move to the Chicago area like so many Baltic refugees

- 198x: native country still USSR occupied, USSR still actively targeting US exiles.

I can perfectly imagine such a person to: - condemn nazi crimes, particulary anti-semitic ones - always have been respectful towards ever human - be scared of deportation to an occupied native country without an independent judiciary - be very supportive of rigorous due process for Baltic emigres

markvdb··on The Blue Collar Jobs of Philip Glass
I invite you to read the book or read one of the interviews with the author. It goes so much wider than FIRE. Rather than a guide, it's an invitation to build your strategy. That should workas an individual or a couple, with or without children.

Frameworks and examples now exist showing how to gain this freedom. Jacob Lund Fisker[0]'s ERE[1] in particular is an interesting system theory based approach .

markvdb··on The Social Recession: By the Numbers
Are cross-cultural and/or cross-national couples also part of this trend? I imagine there to be a growing number of cross-cultural couples with rising mobility. Hooking into traditional social life with one partner less aware of those traditions is less trivial.

Let me also speculate that living between countries especially takes a toll on social life due to the time invested in commuting.

markvdb··on Ask HN: Nuclear plants in war zones: A valid reason not to build more
A lot has happened since 2017. There's been enormous evolution in:

- solar and wind electricity generation: drastic cost reduction, massive scale-up

- interconnects: lower cost, strong growth, especially in the EU

- green hydrogen ecosystem: incredible cost reduction, massive scale-up

- battery storage: drastic cost reduction, massive scale-up

- pumped hydro storage: eking out the last bits

- other storage tech: liquid metal, compressed CO2, ...

- heat pumps: massive scale-up, incremental efficiency improvements, also large scale sea source like Helsinki

I'm especially hopeful when it comes to green hydrogen derivatives as energy carriers.

One of the more popular studies in this regard is https://doi.org/10.1016/j.renene.2021.11.067 .

markvdb··on Ask HN: Nuclear plants in war zones: A valid reason not to build more
There's a lot of reasons for optimism. Renewables plus storage are getting better than nuclear in so many ways. This alternative is faster to deploy, more resilient, (getting) less dependent on questionable imports, (getting) cheaper. The only structural disadvantage is space requirements, but even in that area, there is research on the benefits of symbiosis, like between agriculture and solar.

My experience tells me that no lobbyist will be able to fend off something intrinsically better in the long term.

markvdb··on Liz Truss resigns as UK prime minister
Her government proposed an unfunded budget that caused a gilt market panic. Part of the mortgage market dried up. Variable mortgage rates exploded. Pension funds had to resort to emergency measures. The Bank of England had to intervene.
markvdb··on Ammonia combustion engines: latest research (2021)
I see a certain elegance rather than absurdity in closed cycle green energy storage. Whether H2, NH3, CH4 or something else, chances are that will require high quality CO2 sources. Both CO2 based electric power plants and cement factories look like excellent candidates.

I find the simplicity of compressed CO2 energy storage [0] ten times more elegant, but I'll be happy with any progress towards scalable distributed abundant cheap energy storage.

markvdb··on Ammonia combustion engines: latest research (2021)
Thank you for your comment. I'm really looking for a more extensive overview, an extensively motivated educated guess.

For example, catching CO2 might be done much more cheaply when burning CH4 at a power station. This might change the equation or not. There also seems to be quite a bit of evolution in reducing the price of carbon capture. [0][1] I seem goals of $30/ton for carbon capture and wonder what factors will change the equation...

markvdb··on Ammonia combustion engines: latest research (2021)
I am trying to get a good overview of how NH3 would work at scale as an energy carrier versus H2 or CH4. Any reason to speculate that one of them will dominate? Have you read any good overview?
markvdb··on Retired U.S. generals, admirals take top jobs with Saudi crown prince
Working for the butcher prince. We don't need that kind of people near any NATO army. Let's hope they stay in Saudi Arabia.

In other news, this is just another symptom of a shrinking US empire. Pax americana is starting to crumble.

markvdb··on Sweden’s incoming cabinet says new nuclear reactors will be built
There is no such thing as a stable country on the time scale required for nuclear energy safety. That requires decades. Humanity cannot provide that.

Enerhodar is not the only example. World war two ended roughly 77 year ago. The US civil war was less than 160 years ago.

markvdb··on Vectis IP Announces Call for Patents Essential to the Opus codec
Vultures are mainly carrion-eaters, scavengers.

Hyenas mainly hunt actively, often in coordinated groups, and not just for the weakest animals.

Opus being a healthy codec, and the attempt at a coordinated attack make the hyena analogy seems more appropriate, to me at least.

markvdb··on Vectis IP Announces Call for Patents Essential to the Opus codec
Hyenas, not vultures. Vultures don't hunt themselves.

markvdb··on 2000-Watt Society
15 kWh of electricity for 100 km of car transportation is realistic for a defensively driven modest electric car. At 500W, that's about 80 km of car use per day. In an electric Hummer or similar, your car energy budget would be gone in 35 km. In a fossil fuel Hummer, getting to the bakery 10 km away might be possible, but only one way.

markvdb··on The absurdity of Europe burning wood for energy
Burning straw is a fairly common practice indeed. Don't confuse hay and straw.

Straw can't be used for feeding animals. It's low nitrogen, high carbon/cellulose. Some houses are built out of straw, not hay for a reason...

markvdb··on Stanley Druckenmiller warns the stock market will be ‘flat’ for an entire decade
Let me guess OP's reasoning.

Most of the HN audience is privileged class by courtesy of being tech savvy. Unlike many others, most of us can keep investing even in less fortunate times when others cannot. Exactly those investments might yield extra high long term returns.

markvdb··on Kevins got a bad rap in France
Low class names are very recognisable in Belgium too. Names ending in "y" in particular. Kenny, Kelly, Lindsay, Jordy, ... I teach and try to go beyond the subconscious biases that come with those names. Not easy.

For those who understand Dutch, "De komomaan" [0][1], by De Neveneffecten is a wonderful BBC animal documentary parody on the life of the common man, with some strong references to these naming stereotypes.
