Hey, guess what? There are no new Security Bulletins this week (at least as of when we are going to press) and there are no new known security vulnerabilities for any part of the software stack of the IBM i platform. We doubt very much that Windows Server can ever say the same thing, and even Linux, which is the only volume operating system that matters, usually has something going on because, like IBM i and Windows Server, it is more than a kernel but a complete set of thousands of programs and tens of millions of lines of code. …Read more

It is a fairly light week for PTF patches for the IBM i platform, so we are going to go off the board a little bit here in the IBM i PTF Guide this week. Winter is coming and while plenty of us love this season, or all four of them, some of us are not happy when the snow flies.
