Wake up! It's HighScalability time: Curious how SpaceX's satellite constellation works? Here's some fancy FCC reverse engineering magic. ( Delay is Not an Option: Low Latency Routing in Space , Murat ). Do you like this sort of Stuff? Please support me on Patreon. I'd really appreciate it. Know anyone looking for a simple book explaining the cloud? Then please recommend my well reviewed (30 reviews on Amazon and 72 on Goodreads!
I was recently conducting some exploratory work for a potential client when I hit upon a pretty severe flaw in a design decision they’d made: They’d built a responsive image lazyloader in JavaScript which, by design, worked by: immediately applying display: none; to the ; waiting until the very last of the page’s images had arrived; once they’d arrived, removing the display: none; and gradually fading the page into visibility.
I was honored to write a preface to the great new book Master Apache JMeter. From load testing to DevOps. Here it is: An important event, directly related to this book, happened recently and probably went unnoticed. It appears that Apache JMeter became the most popular load testing tool. In 2014, I was preparing a presentation about load testing tools and criteria for their selection.
People often ask me if developing for the cloud is any different from developing on-premises software. It really is. In this post, I show some of the reasons why that's true, using the Amazon Redshift team and the approach they have taken to improve the performance of their data warehousing service as an example. The Amazon Redshift team has delivered remarkable gains using a few simple engineering techniques: Leveraging fleet telemetry.
Uber’s software architectures consists of thousands of microservices that empower teams to iterate quickly and support our company’s global growth. These microservices support a variety of solutions, such as mobile applications, internal and infrastructure services, and products along with complex … The post Observability at Scale: Building Uber’s Alerting Ecosystem appeared first on Uber Engineering Blog.
Improving the speed at which a web page is displayed often means making the browser’s life as easy as possible. When the browser receives an HTTP response, it actually receives text encoded in bytes, where each byte or sequence of bytes represents a given character.
I recently picked up a Yubico U2F hardware key and thought I’d try to create a web application that was protected with two-factor hardware-based authentication. Things were going smooth until I realized that it is mandatory to be using HTTPS within your application, even when testing locally. HTTPS is common, but I’d never actually set it up with Node.js because I had always been using services like Cloudflare that configure it for you.
With the rapid growth of online advertising, viewer attention is becoming increasingly scarce. In 2018 alone, total media ad spending will rise 7.4% to $638 billion. Digital media will account for 43.5% of this total ad spend (eMarketer 2018) and will surpass conventional advertising by 2021. With online browsers bombarded with more and more advertising the trick is to capture their limited attention with compelling ads.

In a previous post I showed a chart which plots concurrency [X-axis] against throughput (IOPS) on the Y-Axis. Here is that plot again: Experienced performance chart ogglers will notice the familiar pattern of Littles Law, whereby throughput (X) rises quickly as concurrency (N) is increased. As we follow the chart to the right, the slope flattens out and we achieve a lower increase in throughput , even as we increase concurrency by the same amount at each stage.

As the amount of devices connecting online continues to grow, so does our need for IP addresses. That’s why the Internet is currently in a transition period of migrating from IPv4 to the newest version of the Internet Protocol: IPv6. Today, we’re excited to announce that KeyCDN now fully supports IPv6! This new version of the Internet protocol has been automatically added to all Zones.
There was a great article over on The Conversation the other day about how poor scientific research is at considering people with different viewpoints and backgrounds. Specifically, the vast majority of what we know about human psychology and behavior comes from studies conducted with a narrow slice of humanity – college students, middle-class respondents living near universities and highly educated residents of wealthy, industrialized and democratic nations.
