Distributed Systems and the Butterfly Effect

The late science fiction author Ray Bradbury’s short story classic“Jurassic Park”film franchise by decades, the follies of technology innovation that allow, among other things, for humans to interact with dinosaurs, predictably goes awry. However, “A Sound of Thunder”’s main theme is not so much about the risks of appeasing humans’ archetypical curiosity about scary beasts as it is about how interconnected our actions are. Bradbury portrays, for example, how the mere accident of going back in time and stepping on a butterfly can set in motion a chain of reaction that eventually leads to cataclysmic events in the future. Subscribe: Fireside.fm | Stitcher | Overcast | TuneIn In today’s IT world of distributed systems built with Kubernetes and container orchestration technologies, it is beginning to emerge just how deep applications really are, as well as how deeply distributed they are. One of the effects this very distributed and connected infrastructure has is reflected in the famous

JavaScript Libraries Are Almost Never Updated Once Installed

JavaScript Libraries Are Almost Never Updated Once Installed

Cloudflare helps run CDNJS, a very popular way of including JavaScript and other frontend resources on web pages. With the CDNJS team’s permission we collect anonymized and aggregated data from CDNJS requests which we use to understand how people build on the Internet. Our analysis today is focused on one question: once installed on a site, do JavaScript libraries ever get updated?

Let’s consider jQuery, the most popular JavaScript library on Earth. This chart shows the number of requests made for a selected list of jQuery versions over the past 12 months:

JavaScript Libraries Are Almost Never Updated Once Installed


Spikes in the CDNJS data as you see with version 3.3.1 are not uncommon as very large sites add and remove CDNJS script tags.

We see a steady rise of version 3.4.1 following its release on May 2nd, 2019. What we don’t see is a substantial decline of old versions. Version 3.2.1 shows an average popularity of 36M requests at the beginning of our sample, and 29M at the end, a decline of approximately 20%. This aligns with a corpus of research which shows the average website lasts somewhere between two and four years. What we don’t see is a decline Continue reading

Testing in the Open

“Automation is not testing”

I recently attended a webinar where the speaker made this comment and it started me thinking about testing in general and what some of the challenges that can present.

We all know that we should be testing, but there are a lot of potential pit falls that one can fall into when starting down this journey. I’m going to jump into the deep end of the pool here and deal with one of the struggles that it took me a while to deal with.

Imagine the following:

  • You have a local device with a REST API
  • You write a library that accesses that REST API
  • You write tests for that library so that it runs against the local devices REST API
  • You push the library to GITHUB so that other people can leverage your work. ( You are a good person, right?)
  • You configure TravisCI or CircleCI for integration testing.
  • You realize all your tests fail because Travis/Circle doesn’t have access to your internal device.

And now your GITHUB badges all show red and no one trusts your code. Which brings us to vcrpy

What’s vcrpy?

Wow! So glad you asked! vcrpy is a REST Continue reading

The Week in Internet News: Apple Backs Away from Encryption Plan

Under pressure: Apple has scrapped plans to allow iPhone users to fully encrypt backups of their devices in iCloud after the U.S. FBI complained it would hinder investigations, Reuters reports. About two years ago, Apple told the FBI that it planned to offer users end-to-end encryption when storing their phone data on iCloud, but its plans seem to have changed. Meanwhile, U.S. Attorney General William Barr and President Donald Trump have continued their pressure for tech vendors to build backdoors in encrypted devices, Politico says.

One high-profile phone: Two United Nations rights experts have accused Saudi Arabia of hacking the phone owned by Jeff Bezos, founder of Amazon.com and owner of the Washington Post, the New York Times says. The hack appears to be an attempt to influence the Post’s coverage of the kingdom, the U.N. people say. The hack of Bezos’ phone appears to have bypassed encryption through spyware, adds a Fortune story.

If it’s good for smartphones: Swiss cryptography firm Teserakt has introduced E4, “a sort of cryptographic implant that Internet of Things manufacturers can integrate into their servers,” Wired reports. The open source tool aims to be a comprehensive encryption solution for IoT.

IBM Power-based cloud instances available… from Google

IBM and Google may be competitors in the cloud platform business, but that doesn't prevent them from working together. Google is partnering with IBM to offer "Power Systems as a service" on its Google Cloud platform.IBM’s Power processor line is the last man standing in the RISC/Unix war, surviving Sun Microsystems’ SPARC and HP’s PA-RISC. Along with mainframes it’s the last server hardware business IBM has, having divested its x86 server line in 2014.IBM already sells cloud instances of Power to its IBM Cloud customers, so this is just an expansion of existing offerings to a competitor with a considerable data center footprint. Google said that customers can run Power-based workloads on GCP on all of its operating systems save mainframes — AIX, IBM i, and Linux on IBM Power.To read this article in full, please click here

The Debate Over Regulating AI Ramps Up

Sundar Pichai, CEO of Google and parent company Alphabet, generated a lot of buzz recently with an op-ed he wrote for the The Financial Times calling for greater regulation of artificial intelligence (AI) technologies, adding a high-profile voice into a debate that has been simmering as innovation around AI, machine learning and deep learning have advanced rapidly. …

Community Collaboration on Notary v2

One of the most productive meetings I had KubeCon in San Diego last November was a meeting with Docker, Amazon and Microsoft to plan a collaboration around a new version of the CNCF project Notary. We held the Notary v2 kickoff meeting a few weeks later in Seattle in the Amazon offices.

Emphasising that this is a cross-industry collaboration, we had eighteen people in the room (with more dialed in) from Amazon, Microsoft, Docker, IBM, Google, Red Hat, Sylabs and JFrog. This represented all the container registry providers and developers, other than the VMware Harbor developers who could unfortunately not make it in person. Unfortunately, we forgot to take a picture of everyone!

The consensus and community are important because of the aims of Notary v2. But let’s go back a bit as some of you may not know what Notary is and what it is for.

The Notary project was originally started at Docker back in 2015 to provide a general signing Continue reading
