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.

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.
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).
Today we are announcing that we are open sourcing the two systems at the heart of our business: SmartDataCenter and the Manta object storage platform. SmartDataCenter is the container-based orchestration software that runs the Joyent public cloud; we have used it for the better half of a decade to run on-the-metal OS containers — securely and at scale.
I've decided that human languages suck. Some suck worse than others though, so I thought I'd write up a guide. You can take this as "your language sucks if...", or perhaps a better view might be "your program sucks if you make assumptions this breaks..."
I'm very pleased to announce a new white paper has been published: Oracle VM Server for SPARC Best Practices.
This paper shows how to configure to meet demanding performance and availability requirements.
As another writer said, 2014 has been a terrible year for women in tech. (Whether in the industry, or in gaming.) Arguably, this is not a new thing, but rather events are reaching a head. Women (some at any rate) are being more vocal, and awareness of women's issues is up. On the face of it, this should be a good thing.
