hackandthink··on Trillions spent and big software projects are still failing
"The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina"

170 years ago is 1855.

hackandthink··on How a French judge was digitally cut off by the USA
Mearsheimer was right in 1993 (nukes).

He was right in 2014:

And he is still right:

This feels like 1979.

hackandthink··on AI isn't replacing jobs. AI spending is
"they're cutting jobs because they know AI spending will pay off."

They think they know.

hackandthink··on Ubios: China's Alternative to UEFI
"UBIOS will be further discussed and revealed by the Global Computing Consortium at the 2025 Global Computing Conference in Shenzhen this November. For a country looking to both bolster its own domestic computing ecosystem and step away from American systems that constrict non-standard hardware implementations, the development of UBIOS may prove to be a major win for China. However, whether UBIOS becomes widely adopted and championed like the open standard RISC-V, or widely abandoned like LoongArch, remains to be seen."

hackandthink··on German government comes out against Chat Control
There is a lot of censorship in Germany. People do not care.

hackandthink··on The Rising Sea: Foundations of Algebraic Geometry Notes
CHAPTER 27 The twenty-seven lines on a cubic surface

"You are now ready to be initiated into the secret fellowship of the twenty-seven lines."

hackandthink··on What Is the Fourier Transform?
Natura non facit saltus.

hackandthink··on Trade in War
I see different degrees of genocide and support.

I am generally against arms deliveries, especially to Israel and Russia.

Sanctions should above all be effective. Russia is difficult to sanction especially if China and India do not play along.

The energy sanctions hurt Germany more than Russia, so I don't support them.

Specifically, I heat with gas in winter and try to reduce my consumption.

hackandthink··on What are the real numbers, really? (2024)
Interestingly, constructive mathematics cannot prove that the Cauchy and Dedekind constructions are isomorphic:

"As often happens in an intuitionistic setting, classically equivalent notions fork. Dedekind reals give rise to several demonstrably different collections of reals when only intuitionistic logic is assumed"

https://arxiv.org/pdf/1510.00641

hackandthink··on Topological Kleene Field Theories: A new model of computation
"that allows the machine to transcend the classical limits of computation"

The Crackpot index is still low. Anyway it is a good read.

hackandthink··on The Roots of the Gaza Genocide
"How could they allow this to go on?"
hackandthink··on What will become of the CIA?
I read Tim Weiner's first CIA book and expect something similar. You learn a lot about the obvious and well-known mistakes and crimes.

But I lack the basic sympathy for these organizations, if they were abolished the world would be a better place.

hackandthink··on Episode with Stephen Kotkin, Stalin biographer and historian
The last minutes:

I find it disturbing that Stephen Kotkin is so afraid of a third world war (USA/China).

I hope it's not based on inside information.

hackandthink··on A List Is a Monad
Just for fun, monads as modalities is missing:

hackandthink··on Douglas Hofstadter on Loops, Beauty, Free Will, AI, God, Utopia and Gaza
A really likeable person. GEB was highly regarded in my peer group. I should have read it more naively myself. But this interview makes me want to read "I am a strange loop".

https://www.ams.org/notices/200707/tx070700852p.pdf

(too bad that I don't like the word "mysterian", otherwise I would join the club)

hackandthink··on Homotopy Equivalences
"Grothendieck conjectured that the infinity groupoid captures all information about a topological space up to weak homotopy equivalence"

The homotopy hypothesis has something mystical about it.

https://math.ucr.edu/home/baez/homotopy/homotopy.pdf

hackandthink··on Researchers using the same data and hypothesis arrive at different conclusions (2022)
Research Objective:

"Does Immigration Undermine Public Support for Social Policy?"

ISSP Data (immigration, welfare attitudes) for 17 countries.

73 independent research teams come to different conclusions, nobody knows why.

hackandthink··on Panjandrum: The ‘giant firework’ built to break Hitler's Atlantic Wall
"Having tried and failed to negotiate a suitable treaty of alliance with the British and French, and fearing an Anglo-French design of involving them in a war with Germany which they would have to fight alone, the Soviets turned to a deal with Hitler."

"The Soviet Union and the Origins of the Second World War" Russo-German Relations and the Road to War, 1933-1941

hackandthink··on Panjandrum: The ‘giant firework’ built to break Hitler's Atlantic Wall
This is a hornet nest.

I once read this from Alain Badiou:

"This separatism at certain moments reached extremes that no one could forget, particularly not the Russian people, knowing that the vast mass of the Nazi-armed and organised armies coming from Russian territory were Ukrainian. The Vlasov army was a Ukrainian army. Today we can even read the history of Ukrainians turning entire villages to blood and fire, including French ones. A good part of the repression of the maquis in central France was carried out by Ukrainians. "

Wikimedia presents Vaslov's army as Russian:

https://en.wikipedia.org/wiki/Russian_Liberation_Army

But Wikipedia about Vlasov (SS Division here):

"He (Himmler) oversaw the creation of the SS-Volunteer Division "Galicia" in October 1943 from Ukrainian volunteers, but that same month he said that Vlasov made him "genuinely anxious."

https://www.versobooks.com/blogs/news/1569-a-present-default... https://www.versobooks.com/blogs/news/1569-a-present-default...

--- Badiou is a strange guy but I trust him.

In general, I have the impression that the historiography of the Nazi collobaration in Central Europe has been politically influenced in recent years.

hackandthink··on Panjandrum: The ‘giant firework’ built to break Hitler's Atlantic Wall
This is Nazi talk.

That was the actual Nazi plan:

https://en.wikipedia.org/wiki/Hunger_Plan

The differentiation between Ukraine and Russia is interesting.

Ukrainian nationalists had also joined the Nazis.

hackandthink··on Panjandrum: The ‘giant firework’ built to break Hitler's Atlantic Wall
The political situation in the 1930s was thoroughly messed up. Britain and France may have had mainly good intentions, but their policies did not prevent the disasters.

Great Britain should have made a pact with the Soviet Union against Hitler much earlier.

Poland was in an extremely difficult situation. But the decision to invade Czechoslovakia with the Germans was certainly not a good idea.

hackandthink··on Death of Michael Ledeen, maker of the phony case for the invasion of Iraq
Jeff Stein smells like a spook.

I'm sure it's his real name, but it still sounds made up.

hackandthink··on India launches attack on 9 sites in Pakistan and Pakistani Jammu and Kashmir
"However, Pakistan was a valuable diplomatic partner, and its government helped the United States achieve a rapprochement with the People’s Republic of China in the early 1970s."

"U.S. prestige was damaged in both nations, in Pakistan for failing to help prevent the loss of East Pakistan and in India for supporting the brutality of the Pakistani regime’s actions"

hackandthink··on Show HN: Formalizing Principia Mathematica using Lean
I would add that there is/was a certain desire for categorical theories.

"In mathematical logic, a theory is categorical if it has exactly one model (up to isomorphism)."

(categorical is stronger than complete)

hackandthink··on Wikipedia’s nonprofit status questioned by D.C. U.S. attorney
The analysis there is not convincing.

It is obvious that Wikipedia admins communicate with each other. The fact that Aljazeera is referenced is also okay.

In fact, this is not the official Israeli narrative, it seems rather trustworthy.

hackandthink··on Show HN: Formalizing Principia Mathematica using Lean
I only see these very initial propositional theorems.

Am I missing something, or has the project only just begun?

hackandthink··on A Math Lesson From Hitler’s Germany (2017)
Mathematics at Göttingen under the Nazis

Saunders Mac Lane

"Now in retrospect, the whole development is a decisive demonstration of the damage done to academic and mathematical life by any subor- dination to populism, political pressure and pro- posed political principles."
