A deep dive into Cron, the five-field scheduler that powers recurring tasks across multi-user systems. We trace its evolution from the brutal minute-by-minute polling of early Unix, through System V’s discrete-event scheduling, to modern standards like Vixie Cron and the OpenCron Patterns Specification—explaining how the leap from “is it time yet?” to “when is the next event?” made scalable, reliable infrastructure possible. Note: This podcast was AI-generated, and sometimes AI can make mist...

Hyaloclastite: Fire, Ice, and the Geological Time Capsule

On a black-sand beach, lava collides with ice or seawater to forge hyaloclastite —glass fragments instantly shattered by thermal shock and cemented into palagonite. In this episode we unravel how non-explosive quench fragmentation creates jigsaw-fit textures that freeze the exact moment of contact, how palagonitization turns loose debris into solid rock, and why these rocks preserve a record of past ice sheets. We’ll explore hyaloclastite layers under glaciers and at mid-ocean ridges, their r...

Threads as Code: Weaving, Recursion, and the Dawn of Computation

Take a journey into how ancient textiles function as living programs. We examine Andean backstrap weaving and Japanese ikat not just as art, but as sophisticated algorithmic systems: from on-the-fly debugging as a weaver adjusts a row, to pre-dyed patterns that compile into the fabric. We connect motifs as macro-operations, recursion in repeating motifs, and the idea that pattern grammars underpin both cosmology and modern CAD-driven looms. A reminder that computation isn't just electronics—i...

Zermelo's Theorem: The First Formal Game Theory Result

We explore Ernst Zermelo's 1913 theorem for two-player, perfect-information, deterministic games. It guarantees that such games are solvable: one side can force a win, or both can force at least a draw. We unpack the non-repetition argument, why it's finite, and how this foundational insight underpins modern game theory, AI, and formal verification—long before backward induction became standard.

Grosswald's Sum of Five Squares Formula

Jacobi’s exact four-square formula makes r4(n) elegant, but five squares lead to deeper territory with half-integral weight forms and L-functions. In this episode we trace Emil Grosswald’s clever reduction of r5(n) to a sum of r4(n), bypassing the circle method to yield a sharp asymptotic, and we unpack the main term, the role of L-series, the cusp-form error, and what this reveals about the boundary between exact formulas and structured approximations in number theory.

Recursive Language Models Beat Context Rot

A deep dive into recursive language models (RLMs) that avoid the context bottleneck by keeping massive context in an external symbolic workspace. The root LLM acts as an active researcher and manager, writing and running code in a REPL to interrogate the context, delegating subtasks to sub-LLMs, and using tools like searches and regex to prune data. We explore how this context-centric decomposition enables long-horizon reasoning, review dramatic gains on the OolongPairs benchmark (moving from...
