Translating source code written in a high-level programming language into an executable binary typically involves a series of steps, namely compiling and assembling the code into object files, and then linking those object files into the final executable. However, there are certain scenarios where it can be useful to apply an alternate approach that involves executing object files directly, bypassing the linker. For example, we might use it for malware analysis or when part of the code requires an incompatible compiler. We’ll be focusing on the latter scenario: when one of our libraries needed to be compiled differently from the rest of the code. Learning how to execute an object file directly will give you a much better sense of how code is compiled and linked together.
To demonstrate how this was done, we have previously published a series of posts on executing an object file:
The initial posts are dedicated to the x86 architecture. Since then the fleet of our working machines has expanded to include a large and growing number of ARM CPUs. This Continue reading
In January 2016, I published the first-ever episode of the Full Stack Journey podcast. In October 2023, the last-ever episode of the Full Stack Journey podcast was published. After almost seven years and 83 episodes, it was time to end my quirky, eclectic, and unusual podcast that explored career journeys alongside various technologies, products, and open source projects. In this post, I wanted to share a few thoughts about saying goodbye to the Full Stack Journey.
First and foremost, let me say that I really enjoyed being the host of the Full Stack Journey podcast—far more than I expected I would, if I’m honest. While I didn’t love the logistics of producing a podcast, I did love getting to talk with folks, hear their stories, and learn about new things. So, while part of me is thankful to have a little less work to do, another part—a larger part—is sad to see it end.
That being said, some of you are probably wondering why it ended. I mentioned that I didn’t enjoy the logistics of producing a podcast; specifically, I didn’t enjoy audio editing. Some folks like it, but I didn’t. It was truly a chore for me. That was Continue reading
The previous BGP-related videos described how fat fingers and malicious actors cause Internet outages.
Today, we’ll focus on the impact of bugs in BGP implementations, from malformed AS paths to mishandled transitive attributes. The examples in the video are a few years old, but you can see similar things in the wild in 2023.

In a world where allocations of “Hopper” H100 GPUs coming out of Nvidia’s factories are going out well into 2024, and the allocations for the impending “Antares” MI300X and MI300A GPUs are probably long since spoken for, anyone trying to build a GPU cluster to power a large language model for training or inference has to think outside of the box. …

In this episode, Michael, Kristina, and Adriana Villela discuss the challenges and benefits of running Kubernetes on Nomad. Adriana shares her experience of using Nomad in a data center, highlighting its simplicity and ease of deployment compared to Kubernetes. The speakers also discuss the differences between the two platforms, the concept of vendor lock-in, and […]

The dashboard displays data gathered from open source Host sFlow agents installed on Data Transfer Nodes (DTNs) run by the Caltech High Energy Physics Department and used for handling transfer of large scientific data sets (for example, accessing experiment data from the CERN particle accelerator). Network performance monitoring describes how the Host sFlow agents augment standard sFlow telemetry with measurements that the Linux kernel maintains as part of the normal operation of the TCP protocol stack.
The dashboard shows 5 large flows (greater than 50 Gigabits per Second). For each large flow being tracked, additional TCP performance metrics are displayed:

Terry Slattery joins Tom and Russ to continue the conversation on network automation—and why networks are not as automated as they should be. This is part one of a two-part series; the second part will be published in two weeks as Hedge episode 204.
The basis of Zero Trust is defining granular controls and authorization policies per application, user, and device. Having a system with a sufficient level of granularity to do this is crucial to meet both regulatory and security requirements. But there is a potential downside to so many controls: in order to troubleshoot user issues, an administrator has to consider a complex combination of variables across applications, user identity, and device information, which may require painstakingly sifting through logs.
We think there’s a better way — which is why, starting today, administrators can easily audit all active user sessions and associated data used by their Cloudflare One policies. This enables the best of both worlds: extremely granular controls, while maintaining an improved ability to troubleshoot and diagnose Zero Trust deployments in a single, simple control panel. Information that previously lived in a user’s browser or changed dynamically is now available to administrators without the need to bother an end user or dig into logs.
Authentication and Authorization are the two components that a Zero Trust policy evaluates before allowing a user access to a resource.
Authentication is the process of verifying the identity Continue reading
Network engineers and architects considering IPv6 can benefit from the experiences of those who have gone before them by avoiding the problems that have bedeviled other deployments. On today's show, your hosts discuss three typical pitfalls and how to get over or around them without falling in.
