Building big systems with remote hardware teams
The product we’re building, a rack-scale computer, is specifically designed to be a centralized, integrated product because that’s what our customers need. This requirement and the design choices we’ve made to meet this need create some daily efficiency challenges for our team. As a remote-first company, we’re…

How secure is merely discarding (TRIMing) all of a SSD's blocks?
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of.

ARM vs. Intel on Amazon’s Cloud: A URL Parsing Benchmark
Twitter user opdroid1234 remarked that they are getting more performance out of the ARM nodes than out of the Intel nodes on Amazon's cloud (AWS). I found previously that the Graviton 3 processors had less bandwidth than comparable Intel systems. However, I have not done much in terms of raw compute power. The Intel…

You cannot have exactly-once delivery (2015)
I’m often surprised that people continually have fundamental misconceptions about how distributed systems behave. I myself shared many of these misconceptions, so I try not to demean or dismiss but rather educate and enlighten, hopefully while sounding less preachy than that just did.

Haiku package management
I’ve long since been a die-hard BeOS fan and have been running the open-source recreation Haiku for many years. I think it’s interesting to explore the “alternative OS” world and consider some great ideas that for whatever reason never caught on elsewhere.
