  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. …

• Some Good Advice About Log4j Mitigation Gotchas

  January 24, 2022 Timothy Prickett Morgan

  The Apache Log4j logging utility written in Java and available since the end of the Dot Com Boom in early 2001, has been installed far and wide into many systems and systems software packages in the more than two decades it has been available. And that is why the zero-day security vulnerability discovered by Chinese computing giant Alibaba on November 24 last year and revealed on December 9 has caused so much concern.

  Log4j is everywhere and that means the Log4Shell vulnerability that Alibaba described makes it particularly scary. But before we get into some of the mitigation advice that …

  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.

  Well, after watching this video here, which you should do when you actually have 18 minutes and 49 seconds to really pay attention, you will never look at snowflakes quite the same way again. An amazing hobby from …
