Nov 1, 2024November 2024 monthly summary for scicloj/noj: Stabilized and modernized the codebase while laying groundwork for upcoming features. Key features delivered include extensive dependency and library upgrades across the ecosystem (test deps updated, clojure.java-time added; general bumps across Kindly, Hanami, Tableplot, Kind-pyplot, SCI; underlying_libraries refreshed; Metamorph.ml, scicloj.ml.xgboost, Tableplot updated), and release version bumps for the 2-alpha series (2-alpha10.1, 2-alpha11, 2-alpha12). Visualization and data science work advanced with Chicago-bike-times plotting improvements (WIP) using clojure.java-time for truncation and reorganized plots, and foundational work on fastmath_vector_geom2d3d (2D/3D geometry). Added Word2Vec examples data and Word Embeddings tutorial drafts to support NLP workflows. Documentation improvements included README updates, wording refinements, updated chapters, and a CHANGELOG entry for 2024-11, culminating in publishing the Echarts tutorial from draft. Core table processing (tablecloth_table_processing) progressed via WIP development, new printing and column-adding examples, and a group-by/aggregation example, complemented by a missing require fix and general cleanup.
