I’ve been working out a minor idea involving the control of some household actions based on local time, but relative to sunrise and sunset rather than a naive time of day. Simon Kennedy’s Astral is a Python module that can compute these times, but its examples focus on retrieval of locations from major cities. Most places aren’t major cities in the module’s list, so I spent a little time to read the source to determine what other entry points were enabled.
Fifteen years ago, I initiated a time-honored tradition among my colleagues in kernel development at Sun: shortly after the first of every year, we would get together at our favorite local restaurant to form predictions for the coming year. We made one-year, three-year and six-year predictions for both our technologies and more broadly for the industry.
When looking back on 2014 from an infrastructure perspective, it’s hard not to have one word on the lips: Docker.
We built DTrace to solve problems; at the start, the problems we understood best were our own. In the Solaris Kernel Group we started by instrumenting the kernel and system calls, the user/kernel boundary. Early use required detailed knowledge of kernel internals. As DTrace use grew—within the team, in Sun and then beyond—we extended DTrace to turn every function and every instruction in user programs into probes. We added stable points of instrumentation both in the kernel and in user-land so that no deep knowledge of program or kernel internals would be required.

I have been looking at Derived Manifest recently so that I can have one manifest to control the installation of Oracle Solaris 11.2 FCS on our dual boot desktops.
A quick blog entry about getting Solaris PXE boot working with Microsoft Windows DHCP server. I was always told it was easy but I never managed to get it to working even though a lot of people I talked to had it working.
The problem was that our network was not correctly configured for PXEbooting. Problem was our network need PortFast enable (Good Ref: Spanning Tree Protocol (STP) and PortFast).
