The so-called experts will tell you it can’t be done; it is not possible to create bug-free software, at least at low-cost for a non-trivial application. Now it seems, we have our first documented case of ostensibly zero-defect software. continue reading…

Until Agile, software processes in general focused on larger projects. When applied to smaller projects they can become cumbersome and inefficient. Agile has demonstrated its value on relatively small projects, but it does not scale up well, and in my opinion some of its core tenets are incompatible with safety-critical development. continue reading…

There are many tools available to developers of high-integrity software to enhance productivity and code quality. Today I will look at some of them in brief. Future articles will explore some of them in more depth. continue reading…

After my oh-so-recent review of Best Kept Secrets of Peer Code Review, I followed up with the author to inform him of the review. I also took the opportunity to tell him that I disagree with him on a few points, not the least of which is the concept that finding a larger number of defects is good. His reply was gracious, and I hope to have an opportunity to further discuss some of these points with him. Meanwhile, I was inspired to carry on my rant here on the home front.

I just finished reading the “Best Kept Secrets of Peer Code Review (Modern Approach. Practical Advice.)“, by Jason Cohen. While this book is available from resellers at Amazon.com, for the time being it is being offered free of charge from Smart Bear Software, a software tool company founded by the book’s author.

An article was brought to my attention recently. It contains an interview with Bjarne Stroustrop, of C++ fame, discussing the language to which he gave life. Aside from a few technical non sequiturs, such as referring to C++ as “the archetypal ‘high level’ computer language (that is, one that preserves the features of natural, human language)”, I found the article rather entertaining.

Most organizations today, and I would venture that all organizations involved in the production of high-integrity code use one or more development standards, in an attempt to improve the quality of the software produced. Among the common types of standards for development are Architecture Standards, Design Standards, and Coding Standards. Verification standards also exist, for the same reason. In this article, I will focus on coding standards, as that is where I have seen the bulk of issues. continue reading…

Prior to my experience in an avionics environment, I had never heard of MC/DC, now I awake in the night shaking. continue reading…

Okay, the news was broken months ago… and I’m still in awe.  The Sony Playstation 3 will be released with a more powerful CPU than is currently available in any computer in a PC format.  Currently, the only computer I know of that will eventually make use of this chip is IBM’s Blade line of servers. No home computing resource even comes close. continue reading…

I’ve read several articles and blog entries where experts argued over the semantics of “software construction” versus “software development”.  Personally, I see little value in the debate.  But I won’t let that stop me from contributing my 2 cents. continue reading…
