Introducing , Spotify’s free open source tool for converting audio into MIDI. Basic Pitch uses machine learning to transcribe the musical notes in a recording. Drop a recording of almost any instrument, including your voice, then get back a MIDI version, just like that. Unlike similar ML models, Basic Pitch is not only versatile and accurate, but also fast and computationally lightweight. It was b

Google collects performance information from millions of opted-in Chrome browsers around the world and uses this information as a performance ranking factor for its search engine. But it also makes this information freely available so that anyone can use it to check the real-world performance of individual websites. Even more significantly, it’s possible to segment this data according to the techn
At the end of 2021, the Chrome team shipped some functionality that has the ability to make or break sites meeting the Core Web Vitals. So, let’s learn a little bit more about the Back/Forward Cache (aka bfcache), and what you can do to test if your website is compatible with it. Barry Pollard strongly encourage sites to run the Back/Forward Cache test, understand any blockers leading to an unsucc
Building load test infrastructure is tricky and poses many questions. How can we identify performance regressions in newly deployed builds, given the overhead of spinning up test clients? To gather the most representative results, should we load test at our peak hours or when there’s a lull? How do we incentivize engineers to invest time…
Performance needs to be built in starting at the code level, and user-centric metrics like time to interactive (TTI), total blocking time (TBT), and first input delay (FID) help you gauge how fast a website is. But modern web pages are heavy and ever-growing in size Introducing Partytown, a lightweight open-source solution that reduces execution delays due to third-party JavaScript by offloading t

The history of pre-receive hooks, how we discovered that the performance was problematic, and how we went about safely replacing them.
There are a few navigation patterns that are often forgotten or dismissed. We can think of them as navigation shortcuts, helping users get where they want to go, faster — without having to use traditional navigation at all. As it turns out, sometimes they are much more effective, especially on large sites with thousands of pages, many of which have been gathering dust over the years. In UX, we can
Who doesn’t love a good timesaver? In this post, we compiled productivity tips and tools to help you in your day-to-day work. You’ll find shortcuts to speed up routine tasks, tools and cheatsheets to enhance your development workflow, as well as ideas and little helpers to stay organized and improve communication with your team.
How we sped up GitHub.com by moving slow, non-critical code into rack.after_reply.
Loading experience is crucial to the user’s first impression and overall usability, so Google defined Largest Contentful Paint (LCP) metric to measure how quickly the main content loads and is displayed to the user. This new attribute will enable us to fine-tune relative resource priority, improve LCP performance, deprioritize JavaScript fetch calls, and much more. Let’s check out fetchpriority an

We’ve spent a lot of time on performance tuning our Apache Flink application. We’ll walk you through key lessons for optimizing large stateful Apache Flink applications
At Shopify we run more than 170,000 tests in our core monolith. Naturally, we're constantly exploring ways to make this faster, and the Test Infrastructure team analyzed the feasibility of introducing a test budget: a fixed amount of time for tests to run. The goal is to speed up the continuous integration (CI) test running phase by accepting more risk. To achieve that goal we used prioritization
Using signals to deliver less, or different, content is a form of progressive enhancement (or graceful degradation depending on how you look at it), whereby extraneous content is only loaded when necessary, but the core functionality of the website still works. In this article, we’ll look at some of the signals that can be used for this.
V8 is Google’s open source high-performance JavaScript and WebAssembly engine written in C++. v8go is a library written in Go and C++ allowing users to execute JavaScript from Go using V8 isolates. Using Cgo bindings allows us to run JavaScript in Go at native performance. The v8go library, developed by Roger Chapman, aims to provide an idiomatic way for Go developers to interface with V8. As it t
I have a handful of good links to articles about performance that are burning a hole in my bookmarks folder, and wanna drop them here to share.
Maintaining a design system is a lot of work. In this article, we will have a look at what solutions fit inside the umbrella of a Design System, and a few important steps and checkpoints you need to keep an eye on throughout your projects. Here, Atila Fassina shares his lessons learned and how a platform such as Backlight can help put together a series of tools to speed up your architecture setup.
How would you measure performance? Unfortunately, there is no silver bullet for measuring performance. Different products will have different benchmarks and two apps may perform differently against the same metrics, but still rank quite similarly to our subjective “good” and “bad” verdicts. Web Vitals are the new gold standard in performance due to their direct correlation with the user’s experien
The ability to prebuild codespaces is entering public beta. Enable fast environment creation times, regardless of the size and complexity of your repositories.
By subsetting Font Awesome, we can remove any unused glyphs from the font files that it provides to reduce the overall file size.
