Using Astral from a known location

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.

Get pid, user and command for the particular port in illumos

While the Solaris has the updated netstat with -u flag, illumos requires certain improvements in sockinfo, and possibly, rpcbind (tcpConnCreationProcess shows the old PID for rpcbind, until it did not become a demon). With help of pfiles is possible to obtain the desired information about pid for particular port, so I wrote a small pfiles-based utility which allows to determine the PID, user and command for the particular port:
# ./ptcpstat

Predicteria 2015

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.

2014 in review: Docker rising

When looking back on 2014 from an infrastructure perspective, it’s hard not to have one word on the lips: Docker.

DTrace OEL Dynamic Language Support

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.

Delphix Week of Giving

In the frenzied, insular world of a Silicon Valley startup it can be easy to lose perspective on the broader community in which we live and work.

Oracle Solaris 11 Derived Manifest with Automated Installation

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.


PXE booting for Oracle Solaris using Windows DHCP server

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).

A better illumos...

If you follow illumos very closely, you may already know some of this.

A New Fork

Several months ago, I forked illumos-gate (the primary source code repository for the kernel and system components of illumos) into illumos-core.
