issue 84

Long time no see fellow embedded systems lovers! After months of silence, Embedsys Weekly is back on track with the same concept. A hand-picked list of technical articles selected to be sent directly in your mailbox. The best of each week!

#84 is the new #1 It is historically the #84 but if we are completely honest, we can consider it as a new #1. No newsletter for months, and above that we lost all the list in an outage. Yes you heard it. We start over the newsletter from 0 this week! Anyway, we are already few new subscribers and I count on you to share this edition with your colleagues to help us to move the needle one subscriber at a time. Thank you very much!

On another news, we added to the family our new job board dedicated to embedded systems. It will be as well a new section for this newsletter but limited to 1 or 2 jobs not more than that. Posting is free currently. Yes, free! If a job is open at your company, we believe that our job board is a great opportunity to reach thousands of passionate people like you. And who doesn’t like to work with someone sharing a passion?

Please, contact us by email if you have any questions. Enjoy.

EMBA - The security analyzer for embedded device firmware
EMBA is a tool built around the idea that securing an embedded firmware is a complex task.
Penetration testing of embedded firmware is quite complex as we have to deal with different architectures, optimized operating systems and special protocols. EMBA is an Open-Source firmware analyzer with the goal to simplify and automate the complex task of firmware security analysis.” ~ Michael Messner, maintainer
