If you're learning to interact with Infrastructure as Code (IaC), you'll need to get accustomed to structured data, which is different from formatted data you're likely accuomsted to with the CLI. Here's some examples of structured data to help you understand the difference.
The post Formatted CLI Data Is Not Good Enough For Automation appeared first on Packet Pushers.
We kick off this edition of the weekend reads with a few articles on security. Misconfigured cloud storage buckets and a failure to implement good password practices are, as always, a major source of security issues.

In late 2015, I was lucky enough to be part of a small crew of authors who launched a new book project targeting “next-generation network engineering skills.” That book, Network Programmability and Automation, was published by O’Reilly and has garnered praise and accolades for tackling head-on the topics that network engineers should consider mastering as the field of network engineering continues to grow and evolve. I was excited about that announcement, and I’m even more excited to announce that the early release of the second edition of Network Programmability and Automation is now available!
The original team of authors—Jason Edelman, Matt Oswalt, and myself—are joined this time around by Christian Adell. Christian works with Jason at Network to Code, and it has been a tremendous pleasure to get to know Christian (a little bit, at least!) as part of this project so far. I am impressed with his knowledge and experience, and I think it really adds to the book. Jason and Matt, of course, need no introductions; they are both industry leaders and are well-known in the network automation space.
Check out Jason and Christian’s announcement blog post here.
I am, once again, humbled and honored Continue reading
It’s been about nine months since Cloudflare announced support for Signed Exchanges (SXG), a web platform specification to deterministically verify the cached version of a website and enable third parties such as search engines and news aggregators to serve it much faster than the origin ever could.
Giving Internet users fast load times, even on slow connections in remote parts of the globe, is to help build a better Internet (our mission!) and we couldn’t be more excited about the potential of SXG.
Signed Exchanges drive quite impressive benefits in terms of performance improvements. Google’s experiments have shown an average 300ms to 400ms reduction in Largest Contentful Paint (LCP) from SXG-enabled prefetches. And speeding up your website usually results in a significant bounce rate reduction and improved SEO.
And if setting up and maintaining SXGs through the open source toolkit is a complex yet very valuable endeavor, with Cloudflare’s Automatic Signed Exchanges it becomes a no-brainer. Just enable it with one click and see for yourself.
Now that Signed Exchanges have been available on Chromium for Android for several months we dove into the change in performance Continue reading

As my career is mainly in Network Engineering, when some talks about Network performance my initial thoughts jump to increase network throughput, Port-Density, High speed and secure interconnect, I recently came across Systems Performance by Brendan Gregg. I have to say I have never ever imagined that the role is sought out, I went through the book (https://www.amazon.co.uk/Systems-Performance-Enterprise-Brendan-Gregg/dp/0133390098) and I was indeed mind blown by the granularity that one can look into an individual system.
I definitely would recommend anyone in Networking/Cloud/Systems Engineering to go through this book if you haven’t t already, it exposes a whole new level of Linux Kernel and E-BPF and Performance methodologies (Chapter 2) which I instantly fell in love with.
When I first saw the book I was under the initial impression that this was meant for Linux system Continue reading
In March, Nvidia introduced its GH100, the first GPU based on the new “Hopper” architecture, which is aimed at both HPC and AI workloads, and importantly for the latter, supports an eight-bit FP8 floating point processing format. …

Liposomal curcumin is a powerful anti-inflammatory that has been shown to be effective in a wide range of inflammatory diseases. It is also a potent antioxidant and has been shown to protect cells from damage caused by oxidative stress.
Liposomal curcumin is thought to be more effective than regular curcumin because it is better absorbed by the body. One study showed that liposomal curcumin was absorbed into the bloodstream four times better than regular curcumin.
Liposomal curcumin has been shown to be effective in treating inflammatory diseases such as arthritis, Crohn’s disease, and ulcerative colitis. It is also thought to be helpful in managing symptoms of Alzheimer’s disease and other forms of dementia.
Liposomal curcumin works by inhibiting the production of inflammatory molecules called cytokines. It is also a powerful antioxidant and protects cells from damage caused by oxidative stress.
There are many potential benefits of liposomal curcumin. Some of the most well-studied benefits include:
Liposomal curcumin has been shown to reduce inflammation in a wide range of inflammatory diseases, including arthritis, Crohn’s disease, and ulcerative colitis. It is thought to work by inhibiting the production of inflammatory molecules called Continue reading
Today, we are announcing experimental support for WASI (the WebAssembly System Interface) on Cloudflare Workers and support within wrangler2 to make it a joy to work with. We continue to be incredibly excited about the entire WebAssembly ecosystem and are eager to adopt the standards as they are developed.
So what is WASI anyway? To understand WASI, and why we’re excited about it, it’s worth a quick recap of WebAssembly, and the ecosystem around it.
WebAssembly promised us a future in which code written in compiled languages could be compiled to a common binary format and run in a secure sandbox, at near native speeds. While WebAssembly was designed with the browser in mind, the model rapidly extended to server-side platforms such as Cloudflare Workers (which has supported WebAssembly since 2017).
WebAssembly was originally designed to run alongside Javascript, and requires developers to interface directly with Javascript in order to access the world outside the sandbox. To put it another way, WebAssembly does not provide any standard interface for I/O tasks such as interacting with files, accessing the network, or reading the system clock. This means if you want to respond to an event from Continue reading
The people running Google Cloud can see the tides of HPC changing and know that, as we discussed only a few months ago, there is a fairly good chance that more HPC workloads will move to cloud builders over time as their sheer scale increasingly dictates future chip and system designs and the economics of processing. …

Cloudflare is expanding our WAF’s threat intelligence capabilities by adding four new managed IP lists that can be used as part of any custom firewall rule.
Managed lists are created and maintained by Cloudflare and are built based on threat intelligence feeds collected by analyzing patterns and trends observed across the Internet. Enterprise customers can already use the Open SOCKS Proxy list (launched in March 2021) and today we are adding four new IP lists: “VPNs”, “Botnets, Command and Control Servers”, “Malware” and “Anonymizers”.
Customers can reference these lists when creating a custom firewall rule or in Advanced Rate Limiting. For example, you can choose to block all traffic generated by IPs we categorize as VPNs, or rate limit traffic generated by all Anonymizers. You can simply incorporate managed IP lists in the powerful firewall rule builder. Of course, you can also use your own custom IP list.
These lists are based on Cloudflare-generated threat feeds which Continue reading
