Researchers have identified a 10-state, 2-symbol Turing machine, dubbed n1, that halts on a blank tape and produces a number of 1s exceeding Graham's number. The machine's exact halting score and its placement at level ω+1 of the fast-growing hierarchy have been formally verified in Coq without relying on any axioms, surpassing the previous BB(10) champion, which sat at level ω.
Google announced that Sheets now preserves custom sort order in pivot tables imported from Excel, rather than reverting them to standard alphanumeric order. Users can also drag and drop rows or columns to reorder pivot table data, with nested child items moving along automatically, and these custom arrangements now persist across sessions and data refreshes. The rollout began today and may take up to 15 days to reach all users.
An Entrepreneur contributor argues that modern website design relies on the same principles used in manuscripts, maps and architecture long before the internet existed—hierarchy, imagery, patterns and spatial organization that help people find meaning quickly. The piece contends that clarity, familiar navigation patterns and purposeful imagery are structural necessities rather than stylistic choices.
New analysis argues that leadership should not be viewed as a hierarchy above followership, since attaining a position of authority does not guarantee competence in it. Studies cited show traits like narcissism often help people rise into leadership roles while doing little to make them effective once in charge.
Oxide Computer's engineering team published a technical explainer on how it structures cryptographic keys within its trust quorum system, describing how a rack secret reconstructed from K key shares is used to derive and protect all subsequent keys used after rack unlock. The piece compares key derivation and key wrapping as two complementary mechanisms for propagating that trust down the key hierarchy, each with different tradeoffs for storage and rotation.
A product management analysis describes how many teams keep every idea, from major platform overhauls to minor UI tweaks, in a single flat backlog list. One Head of Product described their 400-item backlog as a two-year-old 'graveyard with a search bar,' where sprint planning devolved into arguing over items with no shared context for comparison.
