Too Old To Rocket Load, Too Young To Die
Rocket Loader is in the news again. One of Cloudflare's earliest web performance products has been re-engineered for contemporary browsers and Web standards.
No longer a beta product, Rocket Loader controls the load and execution of your page JavaScript, ensuring useful and meaningful page content is unblocked and displayed sooner.
For a high-level discussion of Rocket Loader aims, please refer to our sister post, We have lift off - Rocket Loader GA is mobile!
Below, we offer a lower-level outline of how Rocket Loader actually achieves its goals.
Prehistory
Early humans looked upon Netscape 2.0, with its new ability to script HTML using LiveScript, and <BLINK>ed to ensure themselves they weren’t dreaming. They decided to use this technology, soon to be re-christened JavaScript (a story told often and elsewhere), for everything they didn’t know they needed: form input validation, image substitution, frameset manipulation, popup windows, and more. The sole requirement was a few interpreted commands enclosed in a <script> tag. The possibilities were endless.
Soon, the introduction of the src attribute allowed them to import a file full of JS into their pages. Little need to fiddle with the markup, when all the requisite JS for the page Continue reading
History Of Networking – Christian O’Flaherty – The Latin American Internet
In this episode of the History of Networking, we are joined by Christian O’Flaherty of the Internet Society to discuss the growth of the Internet in Latin America, including the unique role internet exchanges have played in the region, and the resulting connectivity patterns.

Montenegro: Learning Coding in Primary School
Although coding has yet to be upgraded from an extracurricular activity, a growing number of countries are introducing programming as part of the school syllabus. Coding is considered a new literacy that is becoming more-and-more important as technology innovation is impacting every field of human knowledge. Educators have a key role in teaching primary school children to be passionate about computer science and stimulating their imagination and spirit of competition to solve problems. Learning how to code starting in elementary school helps pupils acquire skills that will be relevant in tomorrow’s labour market and get the highest-paying entry level jobs as they become college graduates.
Motivated by a successful programming course held in 2017, the Internet Society Montenegro Chapter decided to organize a CodeWeek Java Programming and applied for the Beyond the Net Funding Programme Chapter Small Projects, an initiative intended to assist Internet Society Chapters with financial support to fund small projects such as events, learning opportunities, skill development, and networking with local entities.
“This was more than great. I had fun in every sense of that word. I would recommend this course to every friend. Can’t wait till next year!”
“I like this way of studying. Continue reading

How can web-scale networking improve your campus networks?
When you think of your ideal campus network, the term “web-scale” may not immediately come to mind. After all, the term web-scale is something you’re more likely to associate with the cloud than with your network. But you might be surprised to learn that your ideal campus network fits the definition of a web-scale network to a T.
Fundamentally, a web-scale network functions as a single unit that can grow and change on demand, without requiring hands-on reconfiguration of multiple switches or mass hardware replacement. And because it functions as a single unit, a web-scale network can also give you full visibility into the health of your network, end-to-end.
The primary way web-scale networks achieve this flexibility and visibility is by decoupling or disaggregating the hardware and the network operating system (NOS) that runs on the hardware. Since the advent of specialized hardware networking devices, the operating system and hardware have been tightly coupled together. Proprietary NOSes often have platform-independent code that runs only on specialized hardware. Because of that, upgrading to a new software version often means buying new hardware. In some cases, that may be as simple as buying additional RAM to support the new version. In more Continue reading

Is Network Automation Really Faster?
When you need to change the network configuration, the old cut-and-paste method can be quicker than automation via an API, but there are reasons networking pros need to adopt automation.

If IT and operations teams thought it was hard to contend with BYOD and Shadow IT, they must prepare for the latest siege on IT — the Internet of Things.
Where to Use a VRF
Very early in our careers, we learn about physical and logical network segmentation. Generally speaking, that understanding comes in the form represented by the diagrams below.
Depending on the work environment of an individual, it may take some time before they are exposed to the methods that provide segmentation to routed parts of the network. Looking at the diagram above, let’s think about what is being accomplished in each example. The physical segmentation provides full isolation between the two hosts. This article examines the construct used to extend segmentation into a routed network. We will not get into the configuration details but will share some links to additional content that can provide practical guidance on the configuration.
VLANs only provide segmentation at layer 2. This would provide isolation for things like ARP and other broadcasts. VLANs would also provide full segmentation if a router didn’t exist for a given VLAN. However, it is often necessary to extend this into the routed portions of our networks. In the above example, I would expect properly configured routers and switches to allow the two hosts on the right to communicate with one another. What if that is not the goal? We might consider Continue reading
