A Cure For The Dreaded Heisenbug

A Heisenbug is a particularly nasty type of software problem named after renowned German theoretical physicist Werner Heisenberg.  A pioneer in the field of quantum mechanics, Heisenberg proposed in 1927 that the more precisely you measure the location of a particle, the less you can know about its momentum (mass times velocity).  The same proposition is […]

ARM64 Well-Cast For Future Embedded Apps

Over the past few years, ARM 64-bit processors have made their way into growing numbers of embedded devices from smart phones to gaming boxes. Although the industry has tried to confuse us with a variety of alias names such as AArch64, ARMv8-A, ARMv8 or just plain ARM64, we do get the message. The ARM 64-bit […]

I’m not a big fan of defining something using the same term you are trying to define, but one might also […]

Leveraging Real-Time Linux in Enterprise Applications

Concurrent is celebrating a big anniversary.

I began my own career at Concurrent before the first […]
