Modernizing "less"

I have just spent an all-nighter doing something I didn't expect to do.

I've "modernized" less(1).  (That link is to the changeset.)

Goodbye UW IMAP! Hello Dovecot! Oracle Solaris 11 setup guide for Dovecot

After many years of being faithful to UW IMAP it was time to move on. The move was required since UW IMAP was no longer being supported and I was having problems using it with latest version of Horde Webmail, so I decided to install Dovecot on our Oracle Solaris 11 systems.

I was surprised how easy the installation went to get Dovecot working on Solaris 11, which was pleasing.

Tuning the OpenZFS write throttle

In previous posts I discussed the problems with the legacy ZFS write throttle that cause degraded performance and wildly variable latencies.

Best Practices for Oracle Solaris Network Performance with Oracle VM Server for SPARC

A new document has been published on OTN: "How to Get the Best Performance from Oracle VM Server for SPARC"
by Jon Anderson, Pradhap Devarajan, Darrin Johnson, Narayana Janga, Raghuram Kothakota, Justin Hatch, Ravi Nallan, and Jeff Savit.

It's time already

(Sorry for the political/religious slant this post takes... I've been trying to stay focused on technology, but sometimes events are simply too large to ignore...)
The execution of John Foley is just the latest.  But for me, its the straw that broke the camel's back. 

kstat changes in illumos

One of the nice changes to the kstat (kernel statistics) command in illumos is its conversion to C from perl. There were several areas in the illumos (nee OpenSolaris) code where perl had been used. But these were too few to maintain critical mass and it is difficult for interpreted runtimes to change at the pace of an OS, so keeping the two in lockstep is simply not worthwhile.

ZIO Scheduling and Resilver Workloads

Latency and performance problems in storage subsystems can be tricky to understand and tune. If you've ever been stuck in a traffic jam or waited in line to get into a concert, you know that queues can be frustrating to understand and trying on your patience. In modern computing systems, there are many different queues and any time we must share a constrained resource, one or more queues will magically appear in the architecture.

Install Firefox 30 (latest version) onto Oracle Solaris 11

As you know Oracle Solaris 11 (11.1, 11.2) comes with Firefox 17 ESR and Mozilla 17 ESR, which is very good news. I have had no problems with this version until now when I upgrade our Oracle Database 12c to 12.1.0.2 and found out that I could no longer access the Enterprise Manager Database Express via the browser since you require Firefox 24+.

POSIX 2008 locale support integrated (illumos)

A year in the making... and finally the code is pushed.  Hooray!

I've just pushed 2964 into illumos, which adds support for a bunch of new libc calls for thread safe and thread-specific locales, as well as explicit locale_t objects.   Some of the interfaces added fall under the BSD/MacOS X "xlocale" class of functions.
