33. Functional Quadtrees
A Quadtree is a tree data structure, which is useful for giving more focus/detail to certain regions of your data, while saving resources elsewhere. I could only find a couple tutorials/guides and both were imperative, so I figured it'd be fun to do a functional version in Clojure which runs in the browser.
34. Help, My Java Object Vanished (and the GC Is Not at Fault)
Today I’m going to talk about a recent journey as a HotSpot Java Virtual Machine developer working on the OpenJDK project. While running tests for a new feature, I realized my Java objects and classes were arbitrarily disappearing! What followed was probably the most interesting debugging and fixing experience of my life (so far), which I wanted to share with the world.
35. A lost Amazon world just reappeared in Bolivia
Researchers exploring Bolivia’s Great Tectonic Lakes discovered a landscape transformed over centuries by sophisticated engineering and diverse agricultural traditions. Excavations show how Indigenous societies adapted to dynamic wetlands through raised fields, canals, and mixed livelihoods. Today’s local communities preserve this biocultural continuity, guiding research and conservation.
36. Some models of reality are bolder than others
Some models of reality are bolder than others Digital physics is the body of mathematical and philosophical work treating the universe and the way it works as a giant digital computer. This is often associated with cellular automata, and names like Konrad Zuse, John Von Neumann, Stephen Wolfram, etc. What I find fascinating about this field is that the models it suggests are making very deep metaphysical claims: if they are true, it means that the underlying structure of the world is much different than we think, and radically simpler in a sense. Take the lattice gas automaton for instance. A version of it is an hexagonal cellular automata with very simple collision rules, not more complicated than the famous Rule 30 or 110, for 1D cellular automata. The impressive thing about it is that a simulation running this rule with many particles can be shown to approximate the Navier-Stokes equations, which are the classical complicated mathematics to describe the dynamics of fluids. Following Wolfram, I find it very appealing to consider the idea that the world is not somehow running “hidden mathematics”, somewhere and somehow, to solve some complicated equations in a seemingly magical way, but rather, that things are radically simpler, in that the world is simply implementing a set of trivially simple rules. The world is not concerned with, or made with mathematics, mathematics just emerges, with inherent and irreducible complexity, from extreme simplicity.
