Many engineers just assume that secure hardware boot is, in fact, secure. How does this security work, and just how secure is it, though? David Brown joins Tom Ammon, Eyvonne Sharp, and Russ White on this episode of the Hedge to discuss the secure boot loader in some detail. For more information on the secure boot loader and IoT, see David’s presentation at the Open Source Summit.
Outside of the HPC market where there are a number of companies that have delivered or are working on Arm-based server processors, Ampere Computing is the main independent supplier of Arm-based server chips with its current 80-core Altra chips and its impending 128-core Altra Max chips, which are sampling now and will start shipping in the third quarter. …

With the introduction of Ansible Automation Platform 1.2 at AnsibleFest 2020, Ansible released private Automation Hub. This enables a means to deliver, manage and curate Ansible Automation Platform Certified Content via a central on-premises, self-hosted solution for use by internal automation communities.
This sparked my interest in digging deeper into what private Automation Hub is and how I could leverage it. My initial perception went from a mysterious black box to viewing it as the perfect Ansible Automation Platform sidecar.
I learned quite a bit on how I could optimize it for my environments and wanted to share my findings. Before we start, a brief history of Ansible content and Ansible Content Collections may be helpful.
"Following the light of the sun, we left the Old World." - Christopher Columbus on Ansible Collections
During 2017, the number of modules, roles and content under Ansible's GitHub repository surged. The backlog of issues started to increase as the inflow of new content for different platforms and network appliances/devices outpaced the growth of the Ansible Core team. Various YouTube videos and blog posts provided commentary and insights from the Ansible community. The rapid growth of Ansible content led to the birth Continue reading
In the previous blog post in this series, we explored some of the reasons IP uses per-interface (and not per-node) IP addresses. That model worked well when routers had few interfaces and mostly routed between a few LAN segments (often large subnets of a Class A network assigned to an academic institution) and a few WAN uplinks. In those days, the WAN networks were frequently implemented with non-IP technologies like Frame Relay or ATM (with an occasional pinch of X.25).
The first sign of troubles in paradise probably occurred when someone wanted to use a dial-up modem to connect to a LAN segment. What subnet (and IP address) do you assign to the dial-up connection, and how do you tell the other end what to use? Also, what do you do when you want to have a bank of modems and dozens of people dialing in?

The Greek philosopher Heraclitus is typically attributed as the creator of the well-known phrase “Change is the only constant.” Since I left VMware in 2018 to join Heptio, change has been my companion. First, there was the change of focus, moving to a focus on Kubernetes and related technologies. Then there was the acquisition of Heptio by VMware, and all the change that comes with an acquisition. Just when things were starting to settle down, along came the acquisition of Pivotal by VMware and several more rounds of changes as a result. Today, I mark the start of another change, as I begin a new role and take the next step in my career journey.
Last week, I announced via Twitter that I was leaving VMware to explore a new opportunity. Today, I start at Kong, Inc., as a Principal Field Engineer. Kong, if you aren’t already familiar, is a company focused on service connectivity for modern architectures, with products like their eponymous API gateway and the Envoy-powered Kuma service mesh. I’m really looking forward to getting much more familiar with Envoy, the Kong API gateway, Kuma, and related projects and technologies. I still get to be Continue reading
Covering developments in neuromorphic computing has been something of a piecemeal experience, as happens with all novel architectures. …

Over a decade ago, we entered the high speed switching market with our low latency switches. Our fastest switch then, the 7124, could forward L2/L3 traffic in 500ns, a big improvement over store and forward switches that had 10x higher latency. Combined with Arista EOS®, our products were well received by financial trading and HPC customers.

There are halls and corridors in Cloudflare engineering, dangerous places for innocent wanderers, filled with wild project ideas, experiments that we should do, and extremely convincing proponents. A couple of months ago, John Graham-Cumming, our CTO, bumped into me in one of those places and asked: "What if we ported Doom multiplayer to work with our edge network?". He fatally nerd-sniped me.
Aside by John: I nerd-sniped him because I wanted to show how Cloudflare Workers and Durable Objects are a new architectural paradigm where, rather than choosing between two places to write code (the client, the browser or app, and the server, perhaps in a cloud provider availability zone), there’s a third way: put code on the edge.
Writing code that runs on a client (such as JavaScript that runs in a browser or a native app on a phone) has advantages. Because the code runs close to the end-user it can be highly interactive, there’s almost no latency since it’s literally running on the device. But client-side code has security problems: it’s literally in the hands of the end-user and thus can be reverse engineered or modified. And client-side code can be slow to update as it Continue reading
Internet resilience is the ability of a network to maintain an acceptable level of service at all times. The Internet plays a critical role in society and the COVID-19 pandemic has reinforced the importance of reliable and stable Internet connectivity. However, not all countries have Internet infrastructure that is robust enough to provide an acceptable […]
