Illumos in the Cloud: What is Joyent Up to? [24067]
Deirdré Straughan
For years - decades, even - Sun Microsystems held some of the worlds greatest engineering talent fast in its cozy embrace. Then, as so often happens, acquisition unleashed a storm of change. A year later, a good deal of Sun's top talent has moved on, including some well-known names from Solaris engineering. Im sure this tech diaspora will benefit the industry as a whole, as Sun talent spreads far and wide.
For three years at Sun, I worked closely with top Solaris engineers. Many became friends, so I have kept in touch with those who left, and kept an eye on where they went. A number of the best and brightest settled at a cloud computing company out of San Francisco, called Joyent.
Read on for more from Deirdré and a special offer from Joyent.

Hardware Activity Reporter (HAR) 2.0: Performance Monitoring Using Hardware Counters [23935]
Back in Favor with Application Programmers
The Openomics blog post "Performance monitoring using hardware counters: Releasing HAR 2.0" observes that, Hardware Activity Reporter (HAR) -- relatively little used since the release of Solaris 10 OS -- has returned to favor with version 2.0. HAR combines low-level counts into higher-level metrics more useful to application programmers, such as CPI, FLOPS, MIPS, address bus percentage utilization, cache miss rates, branch and branch miss rates, and stall rates. These metrics help in assessing the fair usage of available processing units, locating bottlenecks and guiding tuning efforts, when needed, notes blogger Frederic Pariente.

Chime Verion 1.5 Released [23835]
Graphical Tool for Visualizing DTrace Aggregations
The Observatory: A Closer Look at Using Oracle Solaris reports on the release of version 1.5 of the Chime Visualization Tool for DTrace. The OpenSolaris website defines Chime as " ... a graphical tool for visualizing DTrace aggregations. It provides an alternative to similar CLI-based tools (such as intrstat) that is more visually appealing and potentially more useful. In particular, its ability to sort columns arbitrarily and display data over time offers convenience and better visibility of system and application behavior." Among the improvements in 1.5 are the ability to include total rows in plots over time; to view sparklines on total rows; the ability to to make the aggregate sampling interval a saved preference independent of the DTrace aggregate option; the ability to scale plots over time with the sampling interval; and the ability to select or hide individual plot lines by clicking on the plot legend. Further the update removes all dependence on third party code.
