With millions of users, resulting in 75 billion package downloads per month, npm has undoubtedly been a huge success and npm 7 is now here (and will also come with Node.js 15.0 next week). Key features include workspaces, installation of peer dependencies, and support for yarn.lock.
Safari, Firefox, Edge and Chrome are removing support for TLS 1.0 and 1.1 in March of 2020. If you manage websites, this means there’s less than a year to enable TLS 1.2 (and, ideally, 1.3) on your servers, otherwise all major browsers will display error pages, rather than the content your users were expecting to find.

Some months ago a feature landed in Xamarin.Forms that seemed to truly polarize the Xamarin.Forms community: support for styling applications using CSS. Some argued that it was an unnecessary introduction to "Web" technology to the native development experience, and others that it simply isn't the right solution to the problem. While I sympathize with the latter opinion and think there's plenty of room for some good debate on the right path forward, I count myself as part of a third camp: I think that CSS is a powerful (and frequently maligned) solution to the problem of styling native mobile applications.
