We’re going back to our roots here at Network Collective and that means we’re going to be spending more time chatting and less time with agendas. In this episode we discuss Russ’s impression of ONUG 2019 in Dallas, the team’s take on solving problems in a meeting, the value of meetings in general, and the slow but steady rise of SDN adoption in the enterprise.

In the past three years, the amount of image data on the median mobile webpage has doubled. Growing images translate directly to users hitting data transfer caps, experiencing slower websites, and even leaving if a website doesn’t load in a reasonable amount of time. The crime is many of these images are so slow because they are larger than they need to be, sending data over the wire which has absolutely no (positive) impact on the user’s experience.
To provide a concrete example, let’s consider this photo of Cloudflare’s Lava Lamp Wall:
On the left you see the photo, scaled to 300 pixels wide. On the right you see the same image delivered in its original high resolution, scaled in a desktop web browser. They both look exactly the same, yet the image on the right takes more than twenty times more data to load. Even for the best and most conscientious developers resizing every image to handle every possible device geometry consumes valuable time, and it’s exceptionally easy to forget to do this resizing altogether.
Today we are launching a new product, Image Resizing, to fix this problem once and for all.
With Image Resizing, Cloudflare Continue reading

Today's Heaving Networking episode delves into Web application firewalls (WAFs) with guest Scott Hogg. We examine how WAFs differ from typical firewalls, the security problems they're trying to solve, how attackers try to bypass them, operational challenges, WAFs and cloud applications, and more.

Russ White recently wrote an interesting blog post claiming how we should not ignore any particular technology just because it was invented by a hyperscaler illustrating his point with a half-dozen technologies that were first used by NASA.

On 13 May, more than a billion users saw the messaging application WhatsApp being updated. At the same time reports appeared that a vulnerability had been used in attacks that targeted an unknown but select number of users and was orchestrated by an advanced cyber actor.
Facebook, the owner of WhatsApp, reported it fixed a vulnerability – a buffer overflow, a fairly well known type of vulnerability – that was, according to media (see references below), used in the spyware product Pegasus from the NSO Group, an Israeli company that sells spyware to governments and intelligence agencies all around the world.
Two observations:

Progressive image rendering and HTTP/2 multiplexing technologies have existed for a while, but now we've combined them in a new way that makes them much more powerful. With Cloudflare progressive streaming images appear to load in half of the time, and browsers can start rendering pages sooner.
In HTTP/1.1 connections, servers didn't have any choice about the order in which resources were sent to the client; they had to send responses, as a whole, in the exact order they were requested by the web browser. HTTP/2 improved this by adding multiplexing and prioritization, which allows servers to decide exactly what data is sent and when. We’ve taken advantage of these new HTTP/2 capabilities to improve perceived speed of loading of progressive images by sending the most important fragments of image data sooner.
This feature is compatible with all major browsers, and doesn’t require any changes to page markup, so it’s very easy to adopt. Sign up for the Beta to enable it on your site!
Basic images load strictly from top to bottom. If a browser has received only half of an image file, it can show only the top Continue reading
