Case Study: Lethal Firmware Defects - Patriot Missile Failure
During the Gulf War, twenty-eight U.S. soldiers were killed and almost one hundred others were wounded when a nearby Patriot missile defense system failed to properly track a Scud missile launched from Iraq. The cause of the failure was later found to be a programming error in the computer embedded in the Patriot’s weapons control system.

Further Develop Your Embedded Programming Skills this Fall
The following opportunities to learn firmware development best practices remain open:
- Embedded Software Boot Camp® (Oct 21-24) <-- FINAL CHANCE
- Software Reverse Engineering and Security Analysis (Oct 28-30)
- Test-Driven Development (TDD) & Agile (Nov 4-6)
- Embedded Security Boot Camp® (Nov 12-15)
- Embedded Android® Boot Camp (Nov 18-21)
Consult the full course catalog for prices and other details. Beware that prices increase two weeks prior.
Alternatively, consider bringing an instructor to your office for an on-site training for your whole team. Teams of five or more usually find this is more cost effective than attending public courses.

Rule Changes in the 2018 Update of Embedded C Coding Standard
The book Embedded C Coding Standard began as the internal coding standard at a consulting company and was first published in 2008 by that company. In 2013, the book’s cover was given a new look and the standard became known as the Barr Group Embedded C Coding Standard. A 2018 update to the book was released last year with the first substantive changes in a decade.
The primary motivation for making updates was to better harmonize the rules with the MISRA-C Guidelines. The older Barr Group standard made reference to MISRA C:2004, which was superseded by MISRA C:2012. The few known direct conflicts between BARR-C:2013 and MISRA C (stemming from our earlier embrace of ISO C99) were effectively eliminated with their 2012 update. But we wanted to do more than just remove those noted conflicts and push even further in our embrace of harmonization.

ARM-based "Embedded Software Training in a Box"
For a limited time you can save $50 when you buy an Embedded Software Training in a Box kit.
Based on Barr Group’s Embedded Software Boot Camp®, this do-it-yourself training kit allows you to learn from the valuable content of this popular hands-on live training without the need to take a week away from the office and/or travel.
Featured in this kit are an ARM-Cortex microcontroller board from STMicro along with a full set of training materials that includes a series of exercise instructions and solutions. In brief, you get everything the live course attendees do except the instructor.
Use coupon code "KIT_SAVE_50" to receive your $50 discount. This offer ends December 31, 2019!
