  • Setting The Stage For The Next Decade Of Processing

    August 12, 2019 Timothy Prickett Morgan

    It is no secret that Moore’s Law is causing all kinds of grief with chip designers working in all parts of the IT stack. It was bad enough to run out of clock scaling when Dennard Scaling stopped, and the industry has done a great job in making processors more parallel and allowing for them to offload processing to various kinds of accelerators, either on the die, in the package, or in the chassis over high speed interconnects. But even this is running out of gas as processors keep pushing up against the reticle limits of lithography machines because the …

  • Is Authority Collection The Right Thing For IBM i Security?

    August 12, 2019 Alex Woodie

In this follow-on tip, I’ll continue the exploration of this tool with some additional details plus introduce you to an alternative way to run a Code Coverage session.

    It often seems like there aren’t any new ideas any more. Instead, newer versions of old ideas come back around every few decades (1980s fashion is one current example), or in the case of our first featured article this week, every few hundred centuries or so. For instance, the Trojan Horse was likely the inspiration for the most recent method of breaking into data, another idea that isn’t new but is a simple twist that can result in a frightening outcome for IT managers. You can read about “warshipping” as well as get a little taste of the IT news …
