I'm a web engineer (aka. web developer) and I try my best to keep up with the latest and greatest in my field without minimal effort. I need good resources that pack a big bunch but doesn't take all day to digest.
Here are the newsletters I enjoy and almost depend on for my work (in no particular order):
"The free, weekly newsletter of the best AngularJS content on the web." Comes once a week with about 5 or so links to articles about AngularJS.
"Your weekly dose of all things Python!" A mix of recent new projects that have become available on PyPI or GitHub. Also always a nice list of 3-6 articles revolving around Python.
Web Development Reading List
The Changelog Weekly
"Open Source moves fast. Keep up." They have a podcast too which comes out, I think, once a week too. The topics here are highly technical but often more broader and rather "about the tech" as opposed to "how the tech". They have a crips separation of curated content and sponsored content.
"A weekly newsletter about the Go programming language" This one I'm quite new to. It's jampacked with links to projects and articles.
It's configurable. I have it sent to me on a weekly basis. I get two sections "Trending repositories this week" and "Starred by people you follow this week". It's basically just links to GitHub projects. No articles or curated content. I guess it's maybe not a newsletter but it's so useful that I just have to include it.
Which ones do you depend on/love that I should consider?
