The Overflow #8: Minimal and Performant

The Overflow.

January 2020

New year, new-sletter! Welcome to ISSUE #8 of The Overflow, a newsletter by developers, for developers, written and curated by the Stack Overflow team and Cassidy Williams of React Training. You can read more about it here. This week, we talk to a Veteran Who Codes, wonder what the heck dark matter is, and calculate the math of knots.

From the blog

This veteran started a bootcamp for people who went to bootcamp
In 2014, Jerome Hardaway started Vets Who Code, a nonprofit organization dedicated to teaching US military veterans how to code within the JavaScript ecosystem: HTML, CSS, JavaScript, Git, CLI, node.js, webpack, React, Gatsby, and GraphQL. To date, 250 veterans have graduated from the program. This cohort has gone on to find jobs in the industry across 37 states in the US. It’s 100% free to the veterans admitted into the program, 100% remote run, and 100% supported by donations.

Podcast: The Director’s Cutts
This week, we have an interview with Matt Cutts, the administrator of the United States Digital Services. Cutts is a former Google engineer who led up the search giants webspam team. These days the work he and his team do impacts everything from veteran’s services to tax fraud prevention. Check out our conversation on how software developers can make a big impact on how well government works for its people.
