A comparison of ideas behind Dynamo and Cassandra
When you invoke a function in an imperative programming language, you pass arguments to that function. But that function may also operate on global mutable state, meaning there are other factors in the operation of that function than merely the arguments you pass to it. To some extent this kind of contextual, implicit…
The Pixelbook and four other fairly new Chromebooks have the special flag to enable GPU acceleration, making these the first to get the new feature for Linux. This should bring the Android emulator and improved gaming capabilities to Project Crostini.
In this post, I’m going to go through the process of setting up Apple’s A/UX on a Quadra 610. It’s been a long time in the making - I think I had the hardware for nearly a year before I finally got A/UX running properly!

They say “performance is king’… It was true a decade ago and it certainly is now. With more and more data the world generates each day, we need more and more computing power to process it. It used to be the case that some SW vendors preferred to wait for a new generation of HW to speed up their application and did not…
It's no surprise that modern deep-learning libraries have production-level, highly-optimized implementations of most operations. But just what is the black magic that these libraries use that we mere mortals don't? What exactly does one do to "optimize" or accelerate neural networks operations?
I’m working on the Roc Toolkit open-source project, a development kit for realtime audio streaming over the network. You can read more about the project in these two articles: 1, 2. We decided to implement a set of PulseAudio modules that will allow PulseAudio to use Roc as a network transport. Many Linux distros…
