In Emoi Services LLC v. Owners Insurance Company, the Ohio Supreme Court recently found software is an intangible item that cannot experience direct physical loss or damage and, therefore, the plaintiff’s inability to access or use its software during a ransomware attack was outside the scope of its “businessowners” policy.


Searching Google for downloads of popular software has always come with risks, but over the past few months, it has been downright dangerous, according to researchers and a pseudorandom collection of queries.


Here’s a provocative question: Is it possible, given the vast array of security threats today, to have too many security tools?


This debate has proved futile for two reasons. First, the characteristics of any specific application will dictate which venue is more expensive — there is no simple, unequivocal answer. Second — the question implies that a buyer would choose a cloud or on-premises data center primarily because it is cheaper. This is not necessarily the case


The RISC-V architecture looks set to become more prevalent in the high performance computing (HPC) sector, and could even become the dominant architecture, at least according to some technical experts in the field.


Major US carriers are exaggerating the availability Continue reading

Worth Reading: On ChatGPT

One of the best descriptions of what ChatGPT does and what it cannot do I found so far comes from an ancient and military historian. The what is ChatGPT and what is an essay parts are a must-read, the preparing to be disrupted conclusion is pure gold:

I do think there are classrooms that will be disrupted by ChatGPT, but those are classrooms where something is already broken.

I can’t help but think of the never-ending brouhaha about exam brain dumps.

Heavy Networking 666: Improving Quality Of Experience With LibreQoS

Welcome to Heavy Networking! In this episode we discuss LibreQoS, a free and open source software project to help ISPs improve network latency and responsiveness and improve the Quality of Experience (QoE) for their customers. That project is LibreQoS, and it's being used by ISPs and others to ensure stable latency across networks.

The Future Of DPUs In IT Infrastructure – Packet Pushers Livestream With Dell Technologies – Video

Data Processing Units (DPUs) describe the next generation of SmartNICs. They enhance the simple NIC with compute and memory and they have an operating system to host applications and APIs for system call offloads. DPUs can accelerate networking, security, and storage capabilities on servers while preserving CPU resources for applications. The Packet Pushers hosted a […]

What David Flanagan Learned Fixing Kubernetes Clusters

People are mean. That’s one of the first things David Flanagan learned by fixing 50+ deliberately broken Kubernetes clusters on his YouTube series, “Klustered.” In one case, the submitter substituted a ‘c’ character with a unicode doppleganger — it looked identical to a c on the terminal output — thus causing an error that led to Flanagan doubting himself and his ability to fix clusters. “I really hate that guy,” Flanagan confided at the Civo Navigate conference last week in Tampa. “That was a long episode, nearly two hours we spent trying to fix this. And what I love about that clip — because I promise you, I’m quite smart and I’m quite good with Kubernetes — but it had me doubting things that I know are not the fault. The fact that I thought a six digit number is going to cause any sort of overflow on a 64 bit system — of course not. But debugging is hard.” After that show, Klustered adopted a policy of no Unicode breaks. “You only learn when things go wrong,” Flanagan said. “This is why I really love doing Klustered. If you just have a cluster that just works, Continue reading

Technology Short Take 165

Welcome to Technology Short Take #165! Over the last few weeks, I’ve been collecting articles I wanted to share with readers on major areas in technology: networking, security, storage, virtualization, cloud computing, and OSes/applications. This particular Technology Short Take is a tad heavy on cloud computing, but there’s a decent mix of other articles as well. Enjoy!

Networking

  • For a deeper understanding of Kubernetes networking, and in particular the role played by kube-proxy, I highly recommend this post by Arthur Chiao. There is a ton of information here!
  • Denis Mulyalin shows how to use Nornir, Salt, and NetBox to template your network tests. Now if Denis’ site just had a discoverable RSS feed…

Security

  • Aeva Black and Gil Yehuda tackle the conundrum of open source security.
  • If you haven’t looked at Teri Radichel’s series of posts on automating cybersecurity metrics (ACM), you should. There’s quite a bit of good information there.
  • This post on Cedar—a new policy language developed by AWS—is an interesting read. I’m curious as to the constraints that led AWS to develop a new policy language versus using something like Rego (part of Open Policy Agent); this isn’t something the article touches upon.

API Gateway, Ingress Controller or Service Mesh: When to Use What and Why

In just about every conversation on ingress controllers and service meshes, we hear some variation of the questions, “How is this tool different from an API gateway?” or “Do I need both an API gateway and an ingress controller (or service mesh) in Kubernetes?” This confusion is understandable for two reasons: Ingress controllers and service meshes can fulfill many API gateway use cases. Some vendors position their API gateway tool as an alternative to using an ingress controller or service mesh — or they roll multiple capabilities into one tool. Here, we will tackle how these tools differ and which to use for Kubernetes-specific API gateway use cases. For a deeper dive, including demos, watch the webinar “API gateway routes API requests from a client to the appropriate services. But a big misunderstanding about this simple definition is the idea that an API gateway is a unique piece of technology. It’s not. Rather, “API gateway” describes a set Continue reading

Hedge 166: Oblivious DoH with Chris Wood

DNS over HTTPS, or DoH, is designed to protect the end user’s DNS queries from last mile providers—but recursive servers (or resolvers) also have full access to what a user is asking for. How can users preserve their privacy against data collection at recursive servers? ODoH provides one answer. Listen in as Tom Ammon, Chris Wood, and Russ White discuss how ODoH works, and what this means for user privacy.

To DNSSEC or Not?

OARC held a 2-day meeting in February, with a set of presentations on various DNS topics. Here’s some observations that I picked up from the presentations in that meeting.

Aryaka to build new points of presence as enterprises shift to SaaS

So long, and thanks for all the deployments: deprecating Wrangler v1

So long, and thanks for all the deployments: deprecating Wrangler v1
So long, and thanks for all the deployments: deprecating Wrangler v1

Cloudflare Workers allow developers to deploy code instantly across the globe. Wrangler is the CLI tool we build (and use!) to create, modify, and upload Workers. We recently announced a new version of Wrangler with a bunch of new features – including offline development, zero-config startup, and developer tools support. Since then, we’ve been working hard to make the developer experience with version 2 as smooth and enjoyable as possible. We’re confident in what we’ve built and are now planning to officially deprecate version 1.

What’s happening?

Version 1 of Wrangler (@cloudflare/wrangler on npm) is now deprecated, which means no new features or bug fixes will be published unless they’re critical. Beginning August 2023, no further updates will be provided and the Wrangler v1 GitHub repo will be archived. We strongly recommend you upgrade to version 2 (wrangler on npm) to receive continued support. We have a migration guide to make this process easy!

Why?

Our goal is to make development on the Cloudflare platform as smooth and enjoyable as possible. Whether that means simplifying common workflows, incorporating powerful tools into the Wrangler codebase, or opening up Wrangler for use as a library Continue reading
