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:
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.
Fast Failover in SD-WAN Networks
It’s amazing how quickly you get “must have feature Y or it should not be called X” comments coming from vendor engineers the moment you mention something vaguely-defined like SD-WAN.
Here are just two of the claims I got as a response to “BGP with IP-SLA is SD-WAN” trolling I started on LinkedIn based on this blog post:
Key missing features [of your solution]:
- real time circuit failover (100ms is not real-time)
- traffic steering (again, 100ms is not real-time)
Let’s get the facts straight: it seems Cisco IOS evaluates route-map statements using track objects in periodic BGP table scan process, so the failover time is on order of 30 seconds plus however long it takes IP SLA to detect the decreased link quality.

ThinkPad X1 Carbon 2014: 5 years later
I have recently replaced my ThinkPad X1 Carbon 2014 (second generation). I have kept it for more than five years, using it every day and carrying it everywhere. The expected lifetime of a laptop is always an unknown. Let me share my feedback.
My configuration embeds an Intel vPro Core i7-4600U, 8 Gib of RAM, a 256 Gib SATA SSD, a matte WQHD display and a WWAN LTE card. I got it in June 2014. It has spent these years running Debian Sid, starting from Linux 3.14 to Linux 5.4.
This generation of ThinkPad X1 Carbon has been subject to a variety of experiences around the keyboard. We are still hunting the culprits. The layout is totally messed up, with many keys displaced.1 I have remapped most of them. It also lacks physical function keys: they have been replaced by a non-customizable touch bar. I do not like it due to absence of tactile feedback and it is quite easy to hit a key by mistake. I would recommend to Continue reading

In case you want to look beyond the Machine Learning curtain, you might find the Machine Learning Explained article highly interesting. Spoiler: it all started in 1960s with over 2000 matchboxes.
