Below is a list of links and miscellanea with descriptions. Enjoy.

My open source repositories (https://github.com/rickecon). Here is a link to all of the open source repositories that I administer or contribute to on GitHub.
Policy Simulation Library (PSL) (https://pslmodels.org/). The Policy Simulation Library (PSL) is a community of open-source policy model maintainers and collection of the software repositories they maintain for public-policy decision making. PSL is developed by independent projects that meet standards for transparency and accessibility. The PSL community encourages collaborative contribution and makes the tools it develops accessible to a diverse group of users. The PSL code repositories can be accessed through the PSL GitHub organization (https://github.com/PSLmodels.
PSL Foundation (https://psl-foundation.org/) is the 501(c)(3) organization that supports the Policy Simulation Library and advances accessible and reproducible computing in the analysis of public policy. The research, development, maintenance, education, and outreach activities of the PSL Foundation focuses on promoting the application of open source and open science to public policy decision making that will result in a more evidence-based and transparent policy making process.
Open Source Economics Laboratory (OSE Lab) (https://www.oselab.org/) was founded by Richard Evans in January 2017 at the University of Chicago thanks to a generous three-year grant from the Charles Koch Foundation. The OSE Lab has a five-point mission that involves supporting open source, open access teaching, research, and policy tools: (i) create open access training material for computational economics, (ii) support open source research that is collaborative, transparent, and replicable, (iii) support policy-relevant open source applications, (iv) support open source dynamic visualization tools, (v) support web apps for economic models. The OSE Lab is the evolution of the BYU Macroeconomics and Computational Laboratory (MCL) (https://sites.google.com/site/macrocomplab/) that Kerk Phillips and I founded in March 2012 in the Department of Economics at Brigham Young University. The MCL was closed in the summer of 2016.
Quantitative Economics website by Thomas Sargent and John Stachurski (http://quant-econ.net/). This website provides a public source for a series of lectures on quantitative economic modeling with a macroeconomic focus and with computation using either of the two open source programming languages, Python or Julia. They also provide a nice page that describes the relative strengths and weaknesses of each programming language.
Project Euler (https://projecteuler.net/). A nice resource that hones mathematical, algorithmic, and coding skills is Project Euler. This is a web site with a collection of hundreds of difficult mathematical computational problems that are fun and challenging. You can give your Project Euler friend key to your friends, which allows you to track their progress and compete with them at completing problems.
