✨ 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! 💡

🚀 Behold, the magical Buckaroo: because scrolling through #dataframes is apparently the pinnacle of #innovation in 2023! 🐎 Who knew that gluing basic data table functions onto #Jupyter was the revolution we’ve all been waiting for? 🤔 Maybe next, they’ll invent a way to view files in a file explorer. 🤷‍♂️

🧐 Behold, the "revolutionary" Polars Cloud! 🌩️ It's a dazzling breakthrough in making sure your #dataframes can finally do what SQL has been doing for decades. 🎉 Because who doesn't want a shiny new way to reinvent the wheel? 🚀

Playing around with nested #DataFrames and #vectors, and in the end need a #ForLoop to get out of it.

@rye Unfortunately, you've hit my exact areas of anti-#expertise. I've never used #Jupyter. So my suggestions are probably wrong or things you've already tried.

How are you storing the data? As plain Python objects, #numpy arrays, #Pandas #dataframes? If using native Python datatypes, it will use a ton more memory.

Have you looked at packages on PyPI? There are a bunch of hits for "sankey" - some of them use d3.js, but others don't, and might work better.

🐼📦 Do you have pandas dataframes stored in pickle/shelve files?
The new 2.0 version of pandas might break compatibility with previous versions. You might encounter errors when reading your old dataframes.

What an absolute pleasure to use #julialang #DataFrames has become, kudos to all the contributors!

i wanna play around with #nushell #dataframes a bit, anyone got some suggestions for nice and interesting open datasets to query and explore a bit?

If you're interested in #dataframes, seems like it starts to be many of us in Mastodon: @jorisvandenbossche @marcogorelli (#pandas) @maartenbreddels (#vaex) @ritchie46 (#polars) @andygrove (#datafusion) @bkamins (#JuliaLang)

And probably others (feel free to comment with anyone I missed).

Das Abenteuer Julia 👩‍🦰 geht weiter: Covid Explorer mit Pluto, Data Frames, Plots

Mindestens so lange die Corona-Isolation weitergeht, werde ich an meinem Vorhaben festhalten, Julia, die Sprache (nicht nur) für numerisches Rechnen zu lernen. Dazu habe ich passenderweise heute ein Video ausgegraben, in dem der Macher des Kanals Faris Digital einen »Covid Explorer« mit #Julia, #Pluto.jl, #DataFrames.jl und #Plots.jl programmiert http://blog.schockwellenreiter.de/2020/09/2020093001.html #JuliaLang #DataViz #Covid19 #Video-#Tutorial

Intro to Data Frames (with Julia 👩‍🦰)

Ich habe meine Versuche, die (mathematische) Programmiersprache Julia zu lernen, nicht aufgegeben. Daher gibt es am heutigen Freitag eine lehrreiche Playlist mit sechs Videos von Bogumił Kamiński, in der er versucht, Euch und mir die Arbeit mit #DataFrames in Julia beizubringen. Die Playlist ist brandneu (heute online gestellt) und hat eine Gesamtspieldauer von etwa zwei Stunden. http://blog.schockwellenreiter.de/2020/05/2020050802.html #JuliaLang #DataScience #Video-#Tutorial
