Julia Evans published a long list of new(ish) Linux command line tools. For example, did you ever want to have directory listing in nicely formatted JSON? How about ls -l | jc --ls | jq .?
Quite a few of these tools also work on Mac and can be installed with HomeBrew. Some are written in a scripting language, so you could (in theory) also use them on Windows (without WSL).

Today's Heavy Networking, sponsored by Juniper, dives into the custom vs. merchant silicon debate. Juniper makes the case for its Trio 6 ASIC in MX routers. We get into the specifics of Trio 6 capabilities, examine the needs of the multi-service edge, and discuss the technology and business cases for custom hardware.

It’s not hard to see the world has moved away from discrete software releases to a model that favors recurring periodic revenue. Gone are the days of a bi-yearly office suite offering or a tentpole version of an operating system that might gain some features down the road. Instead we now pay a yearly fee to use the program or application and in return we get lots of new things on a somewhat stilted cadence.
There are a lot of things to decry about software subscription models. I’m not a huge fan of the way that popular features are put behind subscription tiers that practically force you to buy the highest, most expensive one because of one or two things you need that can only be found there. It’s a callback to the way that cable companies put their most popular channels together in separate packages to raise the amount you’re paying per month.
I’m also not a fan of the way that the subscription model is a huge driver for profits for investors. If your favorite software program doesn’t have a subscription model just yet you’d better hope they never take a big investment. Because those investors are hungry Continue reading
Welcome to Technology Short Take #153! My personal and professional life has kept me busy over the last couple of months, so things have been quiet here on the blog. I’ve still been collecting links to share with you, though, and here’s the latest collection. I hope you’re able to find something useful here!
kube-proxy, a key part of Kubernetes networking, a bit better? Start here. Arthur Chiao’s post on cracking kube-proxy is also an excellent resource—in fact, there’s so much information packed in there you may need to read it more than once.Michael Levan reviews different VPN options to connect to applications and services in Azure and AWS. You can subscribe to the Packet Pushers’ YouTube channel for more videos as they are published. It’s a diverse a mix of content from Ethan and Greg, plus selected videos from our events. It’s sort of like our podcasts, […]

As part of the recently passed Infrastructure Investment and Jobs Act (Infrastructure Act) in the United States, Congress asked the Federal Communications Commission (FCC) to finalize rules that would require broadband Internet access service providers (ISPs) display a “label” that provides consumers with a simple layout that discloses prices, introductory rates, data allowances, broadband performance, management practices, and more.
While the idea of a label is not new (the original design dates from 2016), its inclusion in the Infrastructure Act has reinvigorated the effort to provide consumers with information sufficient to enable them to make informed choices when purchasing broadband service. The FCC invited the public to submit comments on the existing label, and explain how the Internet has changed since 2016. We’re sharing Cloudflare’s comments here as well to call attention to this opportunity to make essential information accessible, accurate, and transparent to the consumer. We encourage you to read our full comments. (All comments, from Cloudflare and others, are available for public consumption on the FCC website.)
Six years can change a lot of things, and the Internet is Continue reading

When I published a link to the Is MPLS/VPN Too Complex? blog post to LinkedIn, someone asked whether I’m skeptical about service provider SD-WAN services due to lack of skills, and Kristijan Taskovski quickly identified the root cause in his reply:
The argument of a lack of skill is only one that is perpetuated by businesses. It’s not perpetuated by engineers. People that are trained, honed, and knowledgeable are expensive. Expense is the number one enemy for a business.
That’s exactly why I think most managed SD-WAN services will be a dismal failure.

In the first installment of our Community Spotlight series, I asked Geoff Burke from Tsunati to share his experience with Kubernetes and Calico Open Source. Geoff talks about how he got started with Kubernetes, the challenges that led him to search for a Container Network Interface (CNI), and why he has chosen Calico Open Source as his preferred CNI.
If you are just getting started with Kubernetes and curious about where other people start their journey, this blog post provides valuable insight and information.
Q: Please tell us a little bit about yourself, including where you currently work and what you do there.
I’m currently a senior cloud solutions architect at Tsunati. We are a data protection company and we focus on backup and recovery, mainly trying to help service providers enhance their services. We have a lot of virtualization expertise. In fact, I am a Veeam legend and a Veeam Vanguard. I also work quite intensely with Kasten by Veeam, which is a Kubernetes-native backup and recovery migration application.
Q: There are many people who are just getting started with Kubernetes and might have a lot of questions. Could you please talk a little bit about your own journey?
We start debating the nature of technical debt. What is it, how is it created before moving into solutions. Then we take an unexpected turn into operational debt, why its more important and how software defined has delivered solutions here. Also, we dunk on digital transformation.
