vtprint - blast from the past

I recently decided to have a look back at some old stuff I wrote.  Blast from the past stuff.  One of the things I decided to look at was the very first open source program I wrote -- something called vtprint.

Oracle VM Server for SPARC 3.2 - Enhanced Virtual Disk Multipathing

Last month, Oracle released Oracle VM Server for SPARC release 3.2 which includes numerous enhancements. One of these is improvement for virtual disk multipathing, which provides redundant paths to virtual disk so that disk access continues even if a path or service domain fails.

Multipath groups are arranged in an active/standby pair of connections to the same physical media. In case of a path or service domain failure, I/O activity continues on a surviving path.

Triton: Docker and the “best of all worlds”

When Docker first rocketed into the nerdosphere in 2013, some wondered how we at Joyent felt about its popularity. Having run OS containers in multi-tenant production for nearly a decade (and being one of the most vocal proponents of OS-based virtualization), did we somehow resent the relatively younger Docker?

Is Google server nodes the new Mainframe

A friend mentioned that small/middle companies are using mainframes, but I think an argument could be made that Google and Facebook and friends are really creating the new mainframe with there various server nodes that are often made up of custom tasked designed hardware/servers.

First new post after a long rest...

Well time to wake up this blog, will be posting stuff again, beware.

On Blogging (Briefly)

I gave a presentation today on the methods and reasons of blogging for Delphix Engineering.

One of my points was that presentations make for simple blog posts–practice what you preach!

IPv6 and IPv4 name resolution with Go

As part of a work-related project, I'm writing code that needs to resolve DNS names using Go, on illumos.

While doing this work, I noticed a very surprising thing.  When a host has both IPv6 and IPv4 addresses associated with a name (such as localhost), Go prefers to resolve to the IPv4 version of the name, unless one has asked specifically for v6 names.

Rise of mangos

What is mangos?

Those of you who follow me may have heard about this project I've created called mangos.

Mangos is a lightweight messaging system designed to be wire compatible with nanomsg, but is implemented entirely in Go.

There is a very nice write up of mangos by Tyler Treat, which might help explain some things.
