Fewer than I thought:

- http://www.edge.org for long emails about interesting topics.

- A few Stack Exchange weekly newsletters (stackoverflow, programmers, workplace, superuser, stats, data science). The signal to noise ratio can be pretty low but they're easy to skim through.

- Local tech / machine learning groups.

- This week in swing NYC (http://thisweekinswingnyc.wordpress.com/).

I used to get a lot more through rss until Google killed its reader. After halfheartedly looking for alternatives, I decided it wasn't worth it and simply gave up.
