Non-uniform memory access (NUMA) systems have an architecture that attaches memory to "nodes" within the system. CPUs, too, belong to nodes; memory that is attached to the same node as a CPU will be faster to access (from that CPU) than memory on other nodes. This aspect of performance has important implications for programs running on NUMA systems, and the kernel offers a number of ways for user space to optimize their behavior. The NUMA abstraction is now being extended, though, and that is driving a need for new ways of influencing memory allocation; the multi-preference memory policy patch set is an attempt to meet that need.

r software engineers, constant learning comes with the territory. Here are some thoughts on the learning mindset that can help keep you sharp.

Of all the questions I get on Twitter the most common is this: “How do you build a town?” We know how it used to be done, but these last two centuries we have forgotten how to do it.

A few years ago, transportation planners with the state of Washington came up with a great idea: Let’s demolish all of the buildings in the middle of Seattle and build a giant freeway so suburban commuters can drive into the city instead of having to take gross public transit. And then they did it. Seattle existed before I-5 was built, and it’ll exist after it’s gone. But in the meantime, we’re going to have to...

Claiming that taxation is theft is an effective way to signal that you think of yourself as a libertarian of the more radical, uncompromising, and possibly more Rothbard-inspired sort. But are ther…

Year over year, Kubernetes consistently ranks among the most-loved platforms on Stack Overflow’s Developer Survey. It’s not hard to understand why. It offers easy scaling, great stability and reliability, works across many different environments. In short, it offers all the features that developers love. Where it starts to lose its luster, however, is in production.…

For almost 30 years, the number one reason Windows users have given for not running Linux is they couldn't run their programs on it. Now that Windows 365 Cloud PC is almost here that excuse has just been blown to bits.

Analyzing the complicated state of affairs, and the long goodbyes, that come when one TV network or cable channel replaces another. Here are 10 examples.

We, as humans, like to categorize. It makes the world easier to digest. We fit the people around us into labels: users, coworkers, competitors.

Suppose you have a function method that accepts a sized buffer in the form of a pointer plus a length. How defensive do you need to be about validating the parameters? A customer wanted to know, “How can I validate that caller passed a buffer of the declared size?

We've seen some weird cars where you enter through the front of the vehicle: The Microlino The Dodge Deora Now Pininfarina has unveiled a sexy new "virtual" electric concept car, the Teorema, with the opposite approach. You enter from the back. The roofline swings forward on hinges, raising

Cloud native tooling for authorization is an emerging trend poised to revolutionize the way we approach this oft-neglected part of our applications. Open Policy Agent (OPA) is the leading contender to become a de-facto standard for applying policies to many different systems, from workloads running on Kubernetes to requests passing through Istio. In this article…

Seattle is about 40% water, but not all of our bodies of water are created equal. Sixty years ago, Lake Washington was cleaned at the expense of the Duwamish River and the residents who rely on it. Decades of pollution have left a largely immigrant and Indigenous community to bear the environmental burden.

Legislators are spending $400 million to expand broadband, while opening up public internet options. But access for everyone is still a long way off.

What if log data could transform into graphic shapes and patterns? Visualization makes it easier and faster to decipher log data.

Data is beautiful. As a #CitizenScientist, I enjoy gathering data and trying to make sense of the world around me. At work, we use Prometheus to gather metric data from our clusters, and at home, I use Prometheus to gather data from my hobbies. This article explores how to take an application—a Python script that gathers temperature and humidity data from a sensor—and instrument it to provide data in a model that Prometheus can gather.
