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.
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.
Google recently announced the beta release of the Chrome Remote Desktop for Linux. It allows you to remotely connect to a Linux machine from within the Chrome browser. Judging from the early comments in the Google product help forum, setting up the Chrome Remote Desktop on a Linux machine is still rather quirky for certain configurations.

Aspects of Oracle's recent ZS3-2 announcment made me realize this...." Mark Peters about ZS3
My 2012 instructions for building node.js on OpenIndiana still work on recent bits. Now to write some software.
In order to understand how to effectively manage NFS file systems within the Oracle VM Manager, we must first understand the underlying assumption that each NFS server being accessed by Oracle VM servers are for the exclusive use of Oracle VM. It is assumed that no non-Oracle file systems are being shared/exported from a storage array that is part of an Oracle VM environment.
If you are used to using Virtuozzo or OpenVZ containers and are looking to make the switch to the full virtualization solution KVM (Kernel-based Virtual Machine), you may find one very convenient feature missing: the ability to enter into a virtual environment from the parent node.
Of course, the most popular solution used to access KVM VM is simply connecting via SSH. But what if your key gets removed or the SSH service becomes inaccessible? Rest assured, you can use this little trick to gain access directly to a root shell and manage your VM:
