Although this is not really technical content, I have recently started a weekly newsletter with links and summaries of the most interesting stories and articles related to Ulcerative Colitis and Crohn's Disease.
Few years ago, I have written and published an open source generator that exports Countries data in various formats (MySQL, CSV, YAML, FireBird, XML, JSON).
Today, I have finally finished the process of rewriting that app into React.
I hope someone will find it useful.
