DTrace OEL update
A few months ago I took DTrace on OEL for a spin after Oracle announced it. The results were ugly; as one of the authors of DTrace, I admit to being shocked by shoddiness of the effort. Yesterday, Oracle dropped an updated beta so I wanted to see how far they’ve come in the 4+ months [...]

Oracle’s port: this is not DTrace
After writing about Oracle’s port of DTrace to OEL, I wanted to take it for a spin. Following the directions that Wim Coekaerts spelled out, I installed and configured a VM to run OEL with Oracle’s nascent DTrace port. Setting up the system was relatively painless. Here’s my first DTrace invocation on OEL: [root@screven ~]# [...]

For a short while, I ran the flash memory strategy at Sun and then Oracle, so I still keep my ear to the ground regarding flash news. That news is often frustratingly light — journalists in the space who are fully capable of providing analysis end up brushing the surface. With a tip of the [...]

The future of Solaris
In 2005, Sun released the source code to Solaris, described then as the company’s crown jewel. Why do this? The simplest answer is that Solaris had been losing ground to an open source competitor in Linux. Losing ground was a symptom of economics. Students who had once been raised on Solaris were being inculcated with [...]

Leaving Oracle
I joined the Solaris Kernel Group in 2001 at what turned out to be a remarkable place and time for the industry. More by luck and intuition than by premonition, I found myself surrounded by superlative engineers working on revolutionary technologies that were the products of their own experience and imagination rather than managerial fiat.

Fishworks history of SSDs
This year’s flash memory summit got me thinking about our use of SSDs over the years at Fishworks. The picture of our left is a visual history of SSD evals in rough chronological order from the oldest at the bottom to the newest at the top (including some that have yet to see the light [...]
