A New Challenge

About two years ago Joyent began offering Linux instances, running under KVM, stored on ZFS, and secured by Zones (“double hull virtualization”). Since then, I’ve been doing more and more work on Linux performance as customers deploy on these instances. It’s been fascinating to work on both the illumos and Linux kernels at the same time (a Linux guest in an illumos host), with full stack visibility of the guests, and hypervisor, down to metal.

Upcoming Classes

I look forward to seeing some of you at an upcoming class.

My class, "Technology Manager's Survival Guide" is on the Friday afternoon training schedule at LOPSA-East on May 2 in New Brunswick, NJ.

The Total Cost of Unmasked Data

Data breaches make headlines at a regular cadence. Each is a surprise, but they are not, as a whole, surprising.

Another 10 Performance Wins

Following on from my earlier 10 performance wins post, here is another group of 10 I have worked on.

The OpenZFS write throttle

In my last blog post, I wrote about the ZFS write throttle, and how we saw it lead to pathological latency variability on customer systems.

The Failed Promise

My dislike for C++ is well-known by those who know me.  As is my lack of fondness for Perl.

I have a new one though.  Java.  Oracle and Apple have conspired to kill it.
(I should say this much -- its been a long time, about a decade, since I developed any Java code.  Its entirely possible that I remember the language with more fondness than it truly warrants.  C++ was once beautiful too -- before ANSI went and mutated it beyond all hope back in 1990 or thereabouts.)

piCorePlayer

I learned that Logitech has brought the Squeezebox product line to end to life. I’m not prepared to replace (or research what might replace) our current audio infrastructure, so I’m experimenting with a piCorePlayer install to see if a low cost, Raspberry Pi solution can solve this problem, much like OpenSprinkler has addressed home irrigation.

Sorry for the interruption....

Some of you may have noticed that my email, or my blog, or website, was down.

I discontinued my hosting service with BlueHost, and when I did, I mistakenly thought that by keeping my domain registration with them, that I'd still have DNS services.  It was both a foolish mistake, and yet an easy one to make.  (I should have known better...)

Anyway, things are back to normal now, once the interweb's negative caches have timed out...

It does seem unfortunate that BlueHost:
