Two years ago, I had a blog entry describing falling in love with Rust . Of course, a relationship with a technology is like any other relationship: as novelty and infatuation wears off, it can get on a longer term (and often more realistic and subdued) footing – or it can begin to fray. So well one might ask: how is…
As had been rumored for a while, Oracle effectively killed Solaris on Friday . When I first saw this, I had assumed that this was merely a deep cut, but in talking to Solaris engineers still at Oracle, it is clearly much more than that. It is a cut so deep as to be fatal: the core Solaris engineering organization lost…
Let me preface this with an apology: this is a technology love story, and as such, it’s long, rambling, sentimental and personal. Also befitting a love story, it has a When Harry Met Sally feel to it, in that its origins are inauspicious…
My blog post on falling in love with Rust got quite a bit of attention – with many being surprised by what had surprised me as well: the high performance of my naive Rust versus my (putatively less naive?) C. However, others viewed it as irresponsible to report these performance differences, believing that these…
Prologue (2006) I attended my first WWDC in 2006 to participate in Apple’s launch of their DTrace port to the next version of Mac OS X (Leopard). Apple…
I liked Go right away. It was close enough to C and Java to be instantly familiar, the examples and tutorials were straightforward, and I was quickly writing…
Apple announced a new file system that will make its way into all of its OS variants (macOS, tvOS, iOS, watchOS) in the coming years. Media coverage to this…
Canonical announced a few weeks ago that ZFS will be included in the next release of Ubuntu Linux, on by default and fully supported. And it’s no exaggeration…
There was a tremendous amount of reaction to and discussion about my blog entry on the midlife crisis in open source . As part of this discussion on HN, Jay Kreps of Confluent took the time to write a detailed response – which he shortly thereafter elevated into a blog entry .
Long ago as an undergraduate, I found myself back home on a break from school, bored and with eyes wandering idly across a family bookshelf. At school, I had started to find a calling in computing systems, and now in the den, an old book suddenly caught my eye: Tracy Kidder’s The Soul of a New Machine . Taking it off…
Over the summer, I described preparing for my next expedition. I’m thrilled to announce that the expedition is now plotted, the funds are raised, and the bags are packed: together with Steve Tuck and Jess Frazelle , we have started Oxide Computer Company .
Midlife is tough: the idealism of youth has faded, as has inevitably some of its fitness and vigor. At the same time, the responsibilities of adulthood have grown: the kids that were such a fresh adventure when they were infants and toddlers are now grappling with their own transition into adulthood – and you try to…
I, like many people, have a complicated relationship with Twitter. As Adam and I regaled in a recent Twitter Space , it started when debugging the Twitter fail whale in the offices of Obvious in 2007, where I became thoroughly unimpressed with their self-important skipper, Jack Dorsey. In part because I thought he was…
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…
Compensation: the word alone is enough to trigger a fight-or-flight reaction in many. But we in technology have the good fortune of being in a well-compensated domain, so why does this issue induce such anxiety when our basic needs are clearly covered? If it needs to be said, it’s because compensation isn’t merely…
