CODE QUALITY BLOG: Is code coverage analysis necessary? - Blog
October 20, 2014
CODE QUALITY BLOG: When programmers discuss testing, a question that often comes up is how much is enough? Do I need to get 100 percent coverage? Let’s first address the elephant in the room: it’s impossible to fully test a piece of software. Don’t believe me? A 100-line program described by Glennford Myers in the 1976 book "Software Reliability: Principles and Practices" had as many as 1018 unique paths. In reality when you realize that contemporary software often exceeds hundreds of thousands, if not millions of lines of code and you quickly realize how impractical it is to completely test a piece of software.

What's needed to ensure safety and security in UAV software - Story
July 31, 2013
UAVs are not like the remote control stunt plane you unwrapped on your 10th birthday. In their different guises they can be found in civil airspace or flying as integral players in military missions. That makes unmanned systems? safety and security very serious considerations. Accordingly, ISO 14508 and DO-178 could prove helpful in perpetuating safety and security for unmanned systems. Software tools that automate the processes required by these certification standards are easing the burden.

Code Quality: Dynamic & static analysis combined makes engineers & auditors happy - Blog
March 28, 2013
In the good old days, before writing software became “software engineering,” code development was a black art practiced by weird nerdy kids straight out of college. For them, coding was by no means a structured discipline. If you managed to get them to communicate, they might tell you that they were hacking code together and using ad hoc test data to see whether it did what it was supposed to do when they executed it.
