Andreas SchmidtSoll die PHP-Datenbank SQL ersetzen? Nein, das war von Anfang an nie das Ziel. Eher entlasten. Es ist kein Entweder-oder, sondern eine Ergänzung – um die SQL-DB von Analyse-Last zu befreien. Und wenn man schon dabei ist, kann man ja gleich auf DataFrames setzen – stark für Analysen.
Anfang des Jahres habe ich mir eine Frage gestellt: Kann man eine In-Process-DataFrame-Datenbank rein in PHP bauen, die auf den günstigsten Sharehostern läuft – für Webtraffic-Analyse und Sicherheitsanwendungen? Die Idee: Entwickler bringen ihre DB selbst mit, statt auf externe Datenbanken angewiesen zu sein.
Die ersten Tests sahen deutlich besser aus als gedacht. Und so reifte die Idee Stück für Stück, mittlerweile läuft das intensive Testing und Fixing.

What Category Theory Teaches Us About DataFrames
Every dataframe library ships with hundreds of operations. pandas alone has over 200 methods on a DataFrame. Is pivot different from melt? Is apply different from map? What about transform, agg, applymap, pipe? Some of these seem like the same operation wearing different hats. Others seem genuinely distinct. Without a framework for telling them apart, you end up memorizing APIs instead of understanding structure.

N-gated Hacker News✨ Behold the riveting saga of #MicroHaskell #dataframes, where the author heroically attempts to justify their love for obscure languages by rehashing basic concepts. 🤓 Who knew the secret to debating prowess was a countdown timer made in Haskell? Truly groundbreaking stuff! 💡

The beginner track is evolving! It's not enough to talk about NumPy anymore. Many beginners start right with #dataframes, because more & more #ScientificPython libraries support them out of the box.

Francois DionPicked up "Python Polars the definitive guide" by Jeroen Janssens and Thijs Nieuwdorp. The polar bear was already used on another O'Reilly book, but the Iberian lynx is cool.
Never sure how tech books will pan out, but Jeroen's book data science at the command line was a good one, so I am hopeful.
