AMD Gives Nvidia Some Serious Heat In GPU Compute was written by Timothy Prickett Morgan at The Next Platform.
If you are looking to upgrade your X86 server fleet – and there is lots of chatter about how many enterprises as well as hyperscalers and cloud builders are in the financial mood to do that – then the good news is that both Intel and AMD have now rolled out the best serial compute engines they have ever fielded. …

How HPC Is Cooler – Literally was written by David Gordon at The Next Platform.
In late 2023, I added some Go code for use with Pulumi to stand up an Amazon Elastic Kubernetes Service (EKS) cluster “from scratch,” meaning without using any prebuilt Pulumi components (like the AWSX VPC component or the EKS component). The code is largely illustrative for newer users, written to show how to stitch together all the components needed for an EKS cluster. In this post, I’ll show you how to modify that code to use Bottlerocket OS as the node OS for your EKS cluster—and share some information on installing Cilium into (onto?) the cluster.
The example code can be found in the pulumi/eks-from-scratch folder in my “learning-tools” GitHub repository. As I mentioned, it’s written in Go, and the associated README file has full instructions for how to use that code in your own environment. Since the code was intended to be illustrative, I have tried to provide enough comments in the code for readers to be able to decode what’s happening without too much difficulty.
To use Bottlerocket OS on the EKS nodes in your cluster, you’ll have to modify the main.go file. Specifically, changes are needed in the section of code that creates a Continue reading

I am thrilled to embark on this journey to run Product and Engineering at Cloudflare, driving forward the mission of helping build a better Internet.
While I was a graduate student at University of Illinois, the university introduced the Mosaic web browser to students. In addition to being super easy to install and use, it displayed pictures next to text for the first time. This may not seem impressive today, but back then it felt like a magical step forward.
This simple but powerful upgrade opened up the once niche user base from academics to the masses, transforming the world wide web to become an Internet phenomenon. Since then, I’ve always sought to be part of teams that worked on transformational technologies, including Software-as-a-Service, cloud computing, and AI. Innovation is the life blood of every technology company. To this day, I’m inspired by building products and technology that get adopted at mass scale.
The world is in a very interesting moment for technological innovation: the AI landscape is uncharted and developing at an exponential rate; the urgency for enterprises to reduce tech debt and reliance on legacy applications is at an all Continue reading

In the first exercise in the IS-IS labs series, you configured IS-IS routing for IPv4. Before moving on to more complex topics, let’s explore the data structures IS-IS created to represent your network.
A key component of an ISE home lab is having Active Directory installed. In this post I’ll go through setting up basic AD for use with ISE. This post is not going to cover licensing. I’m assuming you are running the eval version, which is good for 180 days, or that you already have a valid license.
My server is running in an ESX environment based on the following specs:
I’m using more than the minimum requirements. Spec it as you like based on what capacity you have available.
The first step is installing the OS. This part is easy and pretty much only requires you to set an Administrator password.
When the server has booted, start by changing the name of the server. It’s better to do this before changing any roles. Go to System Settings -> Computer Name and click Change… Set the desired name. I’m using the name dc01 in my lab. Click OK.
Changing the name is going to trigger a restart. Choose Restart Now.
From Server Manager, click Add roles and features. Click Next until you get to Continue reading

Taiwan’s Fastest AI Supercomputer Goes To Foxconn was written by Timothy Prickett Morgan at The Next Platform.
Failure is an expected state in production systems, and no predictable failure of either software or hardware components should result in a negative experience for users. The exact failure mode may vary, but certain remediation steps must be taken after detection. A common example is when an error occurs on a server, rendering it unfit for production workloads, and requiring action to recover.
When operating at Cloudflare’s scale, it is important to ensure that our platform is able to recover from faults seamlessly. It can be tempting to rely on the expertise of world-class engineers to remediate these faults, but this would be manual, repetitive, unlikely to produce enduring value, and not scaling. In one word: toil; not a viable solution at our scale and rate of growth.
In this post we discuss how we built the foundations to enable a more scalable future, and what problems it has immediately allowed us to solve.
The Cloudflare Site Reliability Engineering (SRE) team builds and manages the platform that helps product teams deliver our extensive suite of offerings to customers. One important component of this platform is the collection of servers that power critical products such as Durable Objects, Workers, Continue reading
I just completed the Programming for Network Engineers (PRNE) learning path training on Cisco U and would like to share this with you: For a limited time, you have FREE…
The post Cisco U – Rev Up to Recert: Programming for Network Engineer appeared first on AboutNetworks.net.
One of the best ways of learning something is building a lab for it. Especially when it comes to complex topics like network authentication. When I started learning about network authentication and Cisco Identity Services Engine (ISE), I found that there wasn’t a lot of clear information on how you build a lab. Not in Cisco documentation and also not on blogs, etc. In this post I’ll explain how I built my lab using CML and ESX.
Having a lab with ISE only is not going to get you very far. At a minimum, I think the following devices are needed in a network authentication lab:
For my lab, I’m using only virtual devices. The focus is on learning network authentication and ISE which is why I’ve setup a very simple PKI, ignoring best practices such as offline root, intermediate CA, and so on. I might lab that at a later stage, but that’s not the current focus.
The topology of my lab is shown below:
Note that some VMs such as the virtual Catalyst Continue reading
This is a quick post to describe how to reclaim disk space being used by an old Windows install. Recently, I upgraded to Windows 11 from Windows 10. I noticed that I was starting to run a bit low on disk space on my SSD. I have a 512 GB SSD and had less than 100 GB available:
I noticed that there is a folder named Windows.old that is 40 GB in size:
The instructions to reclaim the space seemed clear. Go to Settings -> System -> Storage and reclaim the space labeled as Previous Windows installation. However, ther was no such category when I tried:
After some searching and a little bit of thinking, I realized that this is probably a privileges problem. I became local admin by using the PAM tool. Then I ran the disk cleanup util as administrator:
I can now see that there are previous Windows installations:
I select to delete Previous Windows installations:
You have to confirm that it’s OK to delete:
The deletion process starts:
This will take some time…
There is now more space available:
If you’re running low on disk, check if you have previous Windows installations that you can Continue reading
