Here are the articles, videos, and tools that we’ve been excited about this March, and we have a few announcements, the first being about Interrupt’s first Quarterly Panel co-hosted with Phillip from Embedded Artistry, and a blurb about this year’s Embedded Online Conference

We hope you enjoy these links, and we look forward to hearing what you’ve been reading in the comments or on the Interrupt Slack.

Announcements

1. Interrupt and Phillip from Embedded Artistry will be co-hosting quarterly panels with people we enjoy talking to from the embedded space. Our first one is on April 21st at 8:30a PST.

   We’ll be talking to one of my ex-coworkers from Fitbit, Shiva Rajagopal, about essential device metrics to monitor while building & shipping millions of smartwatches! It’ll be a blast.

2. I’ll be presenting at the Embedded Online Conference again this year. This time it’s about Essential Device Metrics. I’m also excited for Dan Saks’ talk on C++ for Embedded and Alvaro’s talk on Debugging.

   If you register for the Embedded Online Conference and use the code MEMFAULT, you’ll receive $100 off the registration fee!
