Prioritizing performance when building our web apps improves the user experience and helps ensure they can be used by as many people as possible. In this article, Michelle Barker will walk you through some of the front-end optimization tips to keep our Vue apps as efficient as possible.
BEM. Like seemingly all techniques in the world of front-end development, writing CSS in a BEM format can be polarizing. But it is – at least in my Twitter
Chief Product Officer Yuhki Yamashita on how to embrace (and enjoy) endless iteration
Why and how I migrated from distributed postgres to distributed sqlite on kentcdodds.com
Meta is deploying a timing protocol, Precision Time Protocol (PTP), that will offer new levels of accuracy and precision to our networks and data centers. We believe PTP will become the global standard for keeping time in computer networks. PTP will benefit today’s products and services and will be a foundational technology behind the development […]
Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. PTP’s predecessor, Network Time Protocol (NTP), provided us with millisecond precision, but as we scale to more advanced systems on our way to building the next computing platform, the metaverse and AI, […]
