Folks attending @PerfNowConf , the Chrome DevTools team are looking for some volunteers to give feedback on the Performance Panel. Come meet us at the front door in the first break after Harry’s talk if that sounds interesting to you! #perfnow

Good morning @PerfNowConf ☀️ Make sure to come to my session right after lunch today (and feel free to chat to me in the halls!). It will be fun and a lot of unexpected context on #webperf you might not be aware of.

The @PerfNowConf conference begins tomorrow in Amsterdam. It is going to be great 👍 For the first time @pcwilliams & @Jason_williams will share the story of how the Bloomberg Terminal uses web tech & what this means for the wider web ecosystem 🎉 If you see us, come say hi 👋
Bloomberg Becomes Browser Over the years, the Bloomberg Terminal has evolved from one of the first computer-based desktop products running on custom hardware, through completely proprietary software running on Windows, to fully adopting the embedded web browser tech stack for the UI, and JavaScript/TypeScript for applications and infrastructure services. This talk will cover our approach to making Chromium and the V8 JavaScript engine the central core of the Bloomberg Terminal, and how we have been able to understand its architecture and performance characteristics in order to deliver the kind of near-real-time responsive UI the Financial Sector demands.
