Review: Dune (2021)

One of the most important classic sci-fi stories is the book "Dune" from Frank Herbert. It was recently made into a movie. I thought I'd write a quick review.

The summary is this: just read the book. It's a classic for a good reason, and you'll be missing a lot by not reading it.

But the movie Dune (2021) movie is very good. The most important thing to know is see it in IMAX. IMAX is this huge screen technology that partly wraps around the viewer, and accompanied by huge speakers that overwhelm you with sound. If you watch it in some other format, what was visually stunning becomes merely very pretty.

This is Villeneuve's trademark, which you can see in his other works, like his sequel to Bladerunner. The purpose is to marvel at the visuals in every scene. The story telling is just enough to hold the visuals together. I mean, he also seems to do a good job with the story telling, but it's just not the reason to go see the movie. (I can't tell -- I've read the book, so see the story differently than those of you who haven't).

Beyond the story Continue reading

Infrastructure 3. Deploying High Performance Pure Virtual Linux Router – 6WIND

Hello my friend,

Network Function Virtualisation (NFV) is not a new topic. There are numerous blogpost and articles, even in our blog, which review this topic. Yet, there is much more we can cover.

Is Linux Suitable for Automation?

It absolutely is. In fact, Linux is the real home for automation systems, as in many cases it hosts the tools you create in Ansible, Python, Bash, Go or any other language. At the same time, in order to effectively work with Linux, you need to know how to automate management and operation of Linux operating system itself. And you will be absolutely capable to do that, once you attend our Continue reading

Mark Zuckerberg, unlike Einstein, did not dream up Facebook out of a sense of moral duty, or a zeal for world peace. This summer, the population of Zuckerberg’s supranational regime reached 2.9 billion monthly active users, more humans than live in the world’s two most populous nations—China and India—combined.


The greatest risk of monopolies is that they’ll obstruct the ideas that will make our homes truly smart. Our “Jetsons” future is on the line.


Given these concerns, it seems especially bizarre that Amazon was willing to reference the price of competing smart thermostats sold via its platform during the launch. Its smart thermostat is “less than half the average cost of a smart thermostat sold on Amazon.com,” the company’s senior vice president of devices and services, Dave Limp, said.


Apple’s co-founder changed how we view tech. A decade after his death, we’ve changed how we view the tech industry, too.


The U.S. government is secretly ordering Google to provide data on anyone typing in certain search terms, an accidentally unsealed court document shows. There are fears such “keyword warrants” threaten to implicate innocent Web users in serious crimes and are more common than previously thought.

What does it mean to cloud-connect the network? Simply put, it means connecting network equipment to the cloud and collecting telemetry, but this simple idea has far-reaching benefits that can up level the support experience for customers and vendors.


This post will focus on a key part of DNSSEC infrastructure — Root KSK ceremonies. These ceremonies exist to provide transparency to the Internet community around the creation, use, and storage of the Root KSK.


Despite 60% surge in dangerous third-party domain registrations, domain security is an underutilized security component to curb phishing and related ransomware attacks.


The term “code debt” in computer programming refers to the idea that certain decisions in writing computer code will lead to future consequences which have to be dealt with.

Worth Reading: Network Validation Evolution at Hostinger

Network validation is becoming another overhyped buzzword with many opinionated pundits talking about it and few environments using it in practice (why am I not surprised?)

As always, there are exceptions. They don’t have to be members of the FAANG club, and some of them get the job done with open-source tools regardless of what vendor marketers would like you to believe. For example, Donatas Abraitis described how the Hostinger networking team gradually implemented network validation using Cumulus VX, Vagrant, SuzieQ, PyTest and Test Kitchen. Enjoy!

Fast Friday Thoughts From Security Field Day

It’s a busy week for me thanks to Security Field Day but I didn’t want to leave you without some thoughts that have popped up this week from the discussions we’ve been having. Security is one of those topics that creates a lot of thought-provoking ideas and makes you seriously wonder if you’re doing it right all the time.

  • Never underestimate the value of having plumbing that connects all your systems. You may look at a solution and think to yourself “All this does is aggregate data from other sources”. Which raises the question: How do you do it now? Sure, antivirus fires alerts like a car alarm. But when you get breached and find out that those alerts caught it weeks ago you’re going to wish you had a better idea of what was going on. You need a way to send that data somewhere to be dealt with and cataloged properly. This is one of the biggest reasons why machine learning is being applied to the massive amount of data we gather in security. Having an algorithm working to find the important pieces means you don’t miss things that are important to you.
  • Not every solution is going Continue reading

Progressive Delivery on OpenShift

Hai Huang Hai is a research scientist at IBM T. J. Watson Research Center. He is a contributing member of Kubernetes, Istio, Iter8 and TPM. We are accustomed to having high expectations of our apps. We want a constant stream of new features and bug fixes, and yet, we don’t want these updates to affect our user experience adversely. As a result, these expectations put a tremendous amount of pressure on developers. This is where

Cloudflare for SaaS for All, now Generally Available!

Cloudflare for SaaS for All, now Generally Available!

During Developer Week a few months ago, we opened up the Beta for Cloudflare for SaaS: a one-stop shop for SaaS providers looking to provide fast load times, unparalleled redundancy, and the strongest security to their customers.

Since then, we’ve seen numerous developers integrate with our technology, allowing them to spend their time building out their solution instead of focusing on the burdens of running a fast, secure, and scalable infrastructure — after all, that’s what we’re here for.

Today, we are very excited to announce that Cloudflare for SaaS is generally available, so that every customer, big and small, can use Cloudflare for SaaS to continue scaling and building their SaaS business.

What is Cloudflare for SaaS?

If you’re running a SaaS company, you have customers that are fully reliant on you for your service. That means you’re responsible for keeping their domain fast, secure, and protected. But this isn’t simple. There’s a long checklist you need to get through to put a solution in your customers’ hands:

  • Set up an origin server
  • Encrypt your customers’ traffic
  • Keep your customers online
  • Boost the performance of global customers
  • Support vanity domains
  • Protect against attacks and bots
  • Scale for growth
  • Continue reading

Video: Introduction to AI/ML Hype

In May 2021, Javier Antich ran a great webinar explaining the principles of Artificial Intelligence and Machine learning and how they apply (or not) to networking.

He started with a brief overview of AI/ML hype that should help you understand why there’s a bit of a difference between self-driving cars (not that we got there) and self-driving networks.

Gartner: Top strategic predictions for 2022 and beyond

Expect the unexpected – that’s just one of the core premises IT leaders need to embrace in the next few years, according to Gartner's top strategic predictions for 2022 and beyond.IT leaders need to be able to move in multiple strategic directions at once, said Daryl Plummer, distinguished research vice president and Gartner Fellow, to the virtual audience at the firm’s IT Symposium/Xpo Americas, held this week.Network certs: Significant raises for the right ones “Resilience, opportunity and risk have always been components of good business strategy, but today these issues hold new meaning,” Plummer said. “This year’s predictions embody how resilience must be built in more non-traditional ways, from talent to business modularity, while opportunity and risk must be viewed with a greater sense of urgency.”To read this article in full, please click here
