The idea of “theories of everything” may be fundamentally wrong All attempts at "unification" or "theories of everything" necessarily add new particles and new ingredients to the theory. Is this a fundamentally flawed approach? bigthink.com/starts-with-... #physics #fundamental #theoretical

#seminar alert! ⏰
Next Tuesday, Frank Hilker from the University of Osnabrück will give a talk in our Ecology Colloquium entitled
"To connect or not connect isolated patches: Total population abundance and failed rescue effects in fragmented landscapes".
Everyone welcome, either in person or via Zoom, the more the merrier! 😀

All young #CS and #IT practitioners should study, in-depth, at least the following #programming paradigms and pillar languages:
Imperative:
• Mechanical—Forth
• Procedural—C
• Objective—SmalltalkDeclarative:
• Functional—ML
• Relational—SQL
• Logical—PrologTheoretic:
• Computability—𝜆-Calculus
• Polymorphic—Hindley-Milner
• Dependent—Martin-LöfThe above is only "my" short-list. Every experienced programmer has "his" short-list of favourites. Regardless, dedicating oneself to the study of one such short-list would equip a young technologist with both practical and theoretical foundations for the rest of his career—provided he does not switch into the MBA lane, upon the first opportunity.
There is a caveat, though. Each of the above subjects stands atop decades of #theoretical research and #practical advances in #computing. For example, Forth, perhaps the simplest one of the lot, could be viewed as a programmer-readable summary of computing history, from von Neumann's seminal paper (1945) at least up to ANSI Forth (1994). And Martin-Löf intuitionistic type theory (1972), arguably the most complex of the lot, was created with the aim to serve as a new foundation of mathematics, possibly reaching back to Euclid. Dependent type theory, even after more than half-a-century, is still a vibrant (HoTT, as it were) research area.
It is plain to see that "mastery" of computing is an endeavour that demands more than life-and-a-half of dedication. So, none of us are true masters thereof. Indeed, for most of us, just to become barely competent in this field requires a careerlong dedication. Hence, the admonition against switching lanes.
Oh and, #practice maybe careerlong, but #learning is lifelong.

The review of an #esoteric tome on #continuations blunders on like an over-caffeinated grad student's fever dream 💤💻. The author can't decide if it's groundbreaking or a $100 paperweight 📚❓. Spoiler: it has no exercises - because who needs practice when you've got #theoretical #ramblings, right? 🤷♂️

🎉 Oh look, another article where someone writes a thesis on how they *totally* could have caught a #backdoor using their favorite niche OS—because #hindsight is 20/20 and #NixOS is the new superhero cape. 🦸♂️🔍 Meanwhile, the rest of the world continues using xz obliviously, because who needs practical #solutions when you have #theoretical ones? 🙄

The Amazing History of #Locality in #Theoretical #Physics#Philosopher #DavidAlbert rambles (his word) for ½ hour on the often gripping (and #funny) #saga of #nonlocality in #scientific #thought. Starting with #fish, he ushers us along to #Bell's #Theorem in the 1960s. It seems we are "inescapably" in the age of nonlocality. Perhaps an age of #TimeTravelers?

@djb (Daniel J. Bernstein) tooted about a new blog post[1] he published. It's here:
https://blog.cr.yp.to/20250118-flight.htmlIt's interesting. He's a #mathematician and software guy that in more recent years has been known mostly for his work in #cryptography, #theoretical and #practical. You're probably using his #Curve25519 every day in your #communications.
I'm not a mathematician (by a long shot), but it's written in a pretty accessible manner - it's not #formulae and #turgid academic #prose.
The central point he's getting at, by my possibly-mistaken understanding of it, is that current "common sense" about when attacks against pre-quantum cryptography like #RSA (and therefore when post-quantum cryptography becomes critical) are badly mistaken - based on bad assumptions about how attacks work, how they're implemented, and on badly #extrapolating from those bad assumptions using logic that doesn't actually represent the way attacks are developed and become practical.
TL;DR is something along the lines of "#quantum cryptographic attacks against RSA will be practical sooner than most people think, and you should be deploying quantum-resistant cryptography now, not later".
It's worth reading if you're at all interested in #crypto and #security stuff.
He also mentions a project he's involved in that has been discussed separately, transparent post-quantum tunnelling for unmodified #server and #client #software. Link in post.
[1] Written more like a conference presentation, FWIW.

@michaelvera's work is available on the #web and as a #PDF.Vera has been a gentle critic of The #KrononautMoon Project. We encourage all civil discourse. One's belief in Time Travel is not a prerequisite when attempting #contact with #TimeTravelers.
