System Architecture

Recently, we interviewed a USAF retired Colonel who was both a combat  veteran and test pilot, Robert “Juice” Newton, with regard to the strategic shift from the land wars to military competition and engagement with peer competitors. Juice has had extensive engagement in the Middle Eastern land wars, and is now focused on advanced technology […]

Two DARPA-developed technologies—a novel decision aid for mission commanders and a rapid software integration tool—played a critical role in the recent Air Force demonstration of the Advanced Battle Management System (ABMS).

WARFARE EVOLUTION BLOG: My last post outlined the strategic reviews and national defense priorities that sit on top of the kill chain. Defense planners at the Defense Advanced Research Projects Agency (DARPA) are now looking at transitioning to a concept they've dubbed the kill web.

On its surface, the BPF virtual machine resembles many other computer architectures; it has registers and instructions to perform the usual operations. But there is a key difference: BPF programs must pass the kernel's verifier before they can be run. The verifier imposes a long list of additional restrictions so that it can prove to itself that any given program is safe to run; getting past those checks can be a source of frustration for BPF developers. At the 2023 GNU Tools Cauldron, José Marchesi looked at the problem of compiling for verified architectures and how the compiler can generate code that will pass verification.

Over the past decade, the desire to share and collaborate has fueled the rise of multiplayer software across many markets and industries…

In 2020, it’s really easy to send money, but still hard to share it.

Like Zero Trust, Zero Data represents a paradigm that organizations can embrace to enhance their overall security posture. But the benefits go far beyond better security.

The eBPF in-kernel virtual machine is approaching its tenth anniversary as part of Linux; it has grown into a tool with many types of uses in the ecosystem. Alexei Starovoitov, who was the creator of eBPF and did much of the development of it, especially in the early going, gave the opening talk at Linux Security Summit Europe 2023 on the relationship between BPF and security. In it, he related some interesting history, from a somewhat different perspective than what is often described, he said. Among other things, it shows how BPF has been both a security problem and a security solution along the way.

When users encounter slow load times or delays in response from any web application or API, they are more likely to abandon it. Caching plays a crucial role in improving performance and efficiency. Here's how it works.

We have tools available to uncover the necessary data and context to support a sophisticated analytics model on cloud costs.

Cloud Native Buildpacks transform your application source code into images that can run on any cloud.

I enjoy how developing Spectral rules to govern an API slows us down to think about what matters. Really this is the biggest problem I see with people building APIs—-they are just moving too fast, and they refuse to slow down and think too deeply about things. I enjoy the frame rate in which Spectral rules attach themselves to the contracts we are producing for our APIs, and I figured I’d further expand on the opportunity to tell some stories around these machine-readable API policies we are applying, or often times not applying consistently across our API operations.
