Analyze and modify your Anki collection with pandas.
Source on Github Language grade: Python gh actions Coveralls Documentation Status Pypi status Gitter License Black

Anki is one of the most popular flashcard system for spaced repetition learning, pandas is the most popular python package for data analysis and manipulation. So what could be better than to bring both together? With AnkiPandas you can use pandas to easily analyze or manipulate your Anki flashcards.

Sunburst

Package for matplotlib.
Source on Github gh actions pre-commit.ci status Documentation Status Pypi status PR welcome Black License
Sunburst is a module to create sunburst plots/Ring Charts/Hierarchical Pie Charts together with the matplotlib package. Quoting Wikipedia:
A ring chart, also known as a sunburst chart or a multilevel pie chart, is used to visualize hierarchical data, depicted by concentric circles. The circle in the center represents the root node, with the hierarchy moving outward from the center. A segment of the inner circle bears a hierarchical relationship to those segments of the outer circle which lie within the angular sweep of the parent segment.
More documentation is available on readthedocs.io and github.
sunburst plot generated with my package
Sunburst plot created with the sunburst package, similar to the diagrams shown by disk usage monitors. Each wedge corresponds to a folder, with the angle of the wedge proportional to its size. If a folder contains a subfolder, the latter is placed "on top" of the folder. Files that are in the folders therefore show up as "missing wedges". Wedges that are too small can be ignored.

ClusterKinG

Cluster sets of histograms in high energy physics phenomenology
Source on Github CI Pre-commit status Coveralls Documentation Pypi Binder Gitter License Black PR welcome
This package provides a flexible yet easy to use framework to cluster sets of histograms (or other higher dimensional data) and to select benchmark points representing each cluster. The package particularly focuses on use cases in high energy physics. A physics use case has been demonstrated in this paper.
Example plot produced by ClusterKinG
Example plot produced by ClusterKinG: clustering of a a three dimensional parameter space results in three distinct clusters. Benchmark points are highlighted with enlarged markers.

Piezo Puzzle

An interactive birthday puzzle
Source on Github gh actions pre-commit.ci status License
An interactive birthday puzzle with a piezo buzzer operated by an atmega8 MCU. Different values can be selected on a rotary dial. For each selected value, letter combinations are communicated with morse code. Once their meaning is understood, they can be brought in the right order to get a code. After this code has been entered, three dial values play different birthday songs.

Relationships between characters are visualized in an interactive network.

InspiderWeb

Visualize networks of citations.
Source on Github License Travis Build Status
InspiderWeb is a tool to analyze networks of papers referencing and citing each other. It automatically looks up the relationship of papers based on information from inspirehep (a large database for papers in high energy physics), then uses the dot language to describe the resulting network. The result can then be plotted by the Graphviz Package and similar programs. Example of a large network of papers. InspiderWeb comes with an easy to use command line interface, but can also be used as a python package to allow for further customization.
InspiderWeb rendering of a network of but a few papers.
Example with very few nodes. Every green node corresponds to a paper from inspirehep, labeled e.g. by the inspirehep citation keys. If saved as a pdf, the nodes are furthermore clickable and open the corresponding paper. Connection between the nodes correspond to citations. Papers can furthermore be ordered by years.

Anki Plug-ins

Plug-ins & Templates for learning (Japanese) with Anki
Anki is a spaced repetition flashcard program that boasts high customizability with Add-ons. Here are a few things I have been working on, while going through the various stages of trying to learn Japanese.
  • Template tester: The styling of Anki's flashcards is governed by templates written in HTML and CSS. This is a small tool to batch generate previews of templates for different user input cases, which comes in handy when maintaining multiple and complicated templates.
    Source on Github License Travis Build Status
  • Ignore duplicates: Customize how and when Anki flags cards as duplicates.
    Source on Github License
  • Sync fields: Add-on to synchronize information/field values between different cards/notes, e.g. including information/mnemonics about the kanji used in Japanese words also on the cards of Japanese words that use them (and add these as exemplary use cases to the kanji cards). Requires substantial configuration.

  • Merge notes: Plug-in to merge a set of notes (flashcards) into another set of notes. Rudimentary Add-on intended for one time use!

  • cbcImport: Adds a new toolbar to Anki's Add Card dialog to load .csv files and then cycle through them, adding cards/vocabulary items step by step.

  • Readings Audio: Add Kunyomi/Onyomi audio to kanji readings flashcards in Anki. Currently not completely functional.

  • Reset Fields: Adds a button to reset all fields in the editor window in Anki.

  • Templates: The styling of Anki's flashcards is governed by templates written in HTML and CSS. Here are the ones I am using to learn Japanese.

A new toolbar for Anki's 'Add Card' dialog (the three framed rows of buttons/labels/checkboxes at the bottom of the dialog) created by cbcImport, allowing to cycle through .csv files to speed up adding cards, while still being able to make changes case by case.

Other tools for learning Japanese

  • RTK Lookup: For people who learn kanji with the books from James Heisig (Remembering The Kanji). A little command line interface that allows to look up multiple kanji by keyword (or parts of it), by parts of the story/mnemonic or by frame number.
    Source on Github License
  • rtk-table-tools: Generates beautiful posters of all JLPT kanji! Also includes a web scraper to get additional information for that purpose.
