John Marzluff is an ornithologist and a professor of Wildlife Science at the University of Washington. In his new book Subirdia, he discusses his study of what happens to the suburban bird population as their landscape changes underneath them—for instance when a wooded area is cleared for new housing, shopping or golf courses. One surprising finding is that bird diversity actually increases in the new environment. Another finding is that the … [Read more...]

Mainframe Code as Intellectual Property

Much like DNA is central to an individual's identity, mainframe application logic is intrinsic to a company's identity.

Companies greatly value their intellectual property.  They devote considerable effort and money to protecting it.  They contractually obligate employees not to compromise it.  And if they discover that a competitor has usurped it, they pursue legal redress with the utmost intensity. Yet many companies neglect some of their most valuable IP: the business logic coded into their mainframe applications. Worse yet, if they’re not careful, the … [Read more...]

Some mainframe sites have already initiated projects to migrate to IBM COBOL 5.1 in hopes of reaping the millions of dollars in CPU savings that come along with the compiler, the first to truly exploit the System z architecture. Other sites are deep into research projects to scope both the effort and the benefits of this migration. For the practitioners charged with these migration tasks, this is one of those classic first-do-no-harm projects.  … [Read more...]

With the release of COBOL 5.1, IBM has finally delivered a compiler that fully exploits the advantages of System z architecture.  As a result, IT organizations recompiling their code in COBOL 5.1 can run their existing mainframe applications with 10-20% less CPU utilization.  That can save companies millions. These aren’t just short-term savings.  Most companies currently using mainframes will keep relying on them for another decade.  So the … [Read more...]

I was affected by the flooding that hit the Detroit area recently.  While cleaning out my basement I was struck by the amount of things I had—for no good reason. Let me explain. Many things I had, I had because they were given to me, or someone wanted me to have it, or it was free.  But I didn't seek them out. I didn't identify a need and then fill it.  I just had them.  Sure, some things I found I could use, but others... not so much. This made … [Read more...]
