Lesson on Relationships in Spring Boot

This is an asynchronous "treasure map" style lesson I put together on the topic of how to implement relationships between entities in Spring Boot.

Check out the interactive lesson treasure map and the supporting GitHub repo.

Animations

I really enjoy making simple animations to explain concepts visually. They say a picture is worth a thousand words, so it follows that every animation frame adds 1,000 times the explanatory power.

Here's a quick example of one:

Check out this page to see some more animations I've made with custom python and matplotlib code to explain statistics and data science concepts.

cods

cods is a deployment tool that automates the setup of, and deployment to, a server with a MySQL database and virtual hosting through nginx which reverse proxies to node.js, python, php, or java web applications, or serves static sites.

Learn more about it.

hlre

hlre is a TUI app that shows the matches of a python flavored regular expression as you type it.

Learn more about it, or install it and play with it yourself!

python3 -m pip install hlre

Pandas Extensions

I built a python module that adds a bunch of additional methods that I frequently use to pandas' data frames and series objects.

import zgulde.extend_pandas

Check out the module itself or the repo that contains it for various other python data science goodies (like my data viz helper functions).

Others

Here are some other miscellaneous projects that I'm also fairly fond of:

• I made a pandoc filter that automatically converts graphviz or plantuml diagrams in markdown files into base64 encoded images in the HTML output. Check it out on GitHub.
• I made a simple blog application with a complicated technology stack. Unit tested clojurescript running with (now deprecated) lumo makeup the backend and react + redux code tested with enzyme makeup the frontend.
• I made blackjack game for the pebble smartwatch. While sadly the pebble is no longer produced, my code still lives on GitHub.
• I wrote an elisp script that lets you browse hacker news inside of emacs. (These days I spend more time in vim and jupyter notebooks though.)
• I made a python command line utility / library for converting a git repository log into a format more useful for data analysis.
