During Katie and Addy’s Google I/O talk , they referred to an internal study that found that 40% of large brands regress on web performance within 6 months. That’s a large, discouraging number, but it’s not entirely surprising. In my experience, teams want to build fast sites. When given the opportunity, like a large organizational push, they relish it and can make tremendous progress.

CheriABI: enforcing valid pointer provenance and minimizing pointer privilege in the POSIX C run-time environment Davis et al., ASPLOS’19. Last week we saw the benefits of rethinking memory and pointer models at the hardware level when it came to object storage and compression ( Zippads ). CHERI also rethinks the way that pointers and memory work, but the goal here is memory protection.

Defining APM. Today's blog post is headed back to the basics. I've been using and talking about APM tools for so many years sometimes it's hard to remember that feeling of not knowing the associated terms and concepts. So for anyone who is looking to learn the basics of what is APM, this blog is for you. What Does APM Stand For? APM stands for Application Performance Management.

One of the quickest wins—and one of the first things I recommend my clients do—to make websites faster can at first seem counter-intuitive: you should self-host all of your static assets, forgoing others’ CDNs/infrastructure. In this short and hopefully very straightforward post, I want to outline the disadvantages of hosting your static assets ‘off-site’, and the overwhelming benefits of hosting them on your own origin.

I recently wrote a tutorial titled, Configuring Visual Studio Code for Arduino Development , because I’ve been exploring the Internet of Things (IoT). Up until recently I’ve only had hands on experience with Raspberry Pi , but I’ve been expanding my knowledge with Arduino. I have an Arduino Uno and a GPS module, so I thought it’d be a good idea to demonstrate how to use the two together.

It’s easy for modern, distributed, high-scale applications to hide database performance and efficiency problems. Optimizing performance of such complex systems at scale requires some skill, but more importantly it requires a sound strategy and good observability, because you can’t optimize what you can’t measure.

This post is intended to present a project that could help with testing the mediation sequences created in WSO2 ESB projects. Using tools like SOAP UI and Postman, we can test our APIs and Proxies by issuing requests to them and validate the response of the services. As this gives us a good start point for testing the integrations, it doesn’t allow us to test the individual pieces that compose the integration, the mediation sequences.

A case for lease-based, utilitarian resource management on mobile devices Hu et al., ASPLOS’19. I’ve chosen another energy-related paper to end the week, addressing a problem many people can relate to: apps that drain your battery. LeaseOS borrows the concept of a lease from distributed systems, but with a rather nice twist, and is able to reduce power wastage by 92% with no disruption to application experience and no changes required to the apps themselves.

Boosted race trees for low energy classification Tzimpragos et al., ASPLOS’19. We don’t talk about energy as often as we probably should on this blog, but it’s certainly true that our data centres and various IT systems consume an awful lot of it. So it’s interesting to see a paper using nano-Joules per prediction as an evaluation metric. The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data.

Slowness comes in two flavors. One flavor includes loading screens, waiting for UI to build up, etc. The other form of slowness involves the UX — such as buttons not being as responsive as expected, default gestures, actions and animations not happening when they are expected to be happening. Both contribute to a bad user experience. In this blog post, I'll dive into the primary causes for an app to feel slow and how you can prevent most of them with a focus on cross-platform app frameworks.

Big tech has historically been lightly regulated. True, both IBM and Microsoft were subject to regulation in 1956 and 2001, respectively, to limit their monopolistic powers. But neither suffered dents in their financial returns as a result (attorney fees notwithstanding), and the tech industry innovated in ways that made their respective monopolistic states very short lived.

If you are developing using Test-Driven Development (TDD), there is a chance that you are doing it the wrong way. The symptoms of this are very clear. If you have a huge test suite that breaks every time you insert a new feature or make a change to the code, and you end up having to rewrite tests to make it pass again, you are there. We've all been there, and sometimes we still are.

Visual testing is the automated process of detecting and reviewing visual UI changes.

The visuals and UI of applications are critical parts of how our users use software, but often teams are still relying on slow, error-prone manual testing processes.

End-to-end testing is done to make sure that the application behaves as expected and the flow of actions from starting to end is complete without any issue. To explain with an example, suppose you are the end user and you are using an app to book a flight. First, you will launch the app and click on the flight’s icon on the home page. Then you will enter the destination, date, and other required details.
