Announcing Flutter 2: Google's Dart-Based Cross Platform App FrameworkFlutter is best associated with mobile app development but now lets you use the same codebase to ship native apps to five operating systems: iOS, Android, Windows, macOS, and Linux, as well as to the Web.

git clone Vulnerability Announced — It’s pretty rare you hear about a vulnerability in git itself. Upgrading is the best option here, but there are some simple mitigations you can apply even on older versions. There’s more details on the issue here but basically “Git could be fooled into running remote code during a clone” of malicious repos.

Google Cloud Introduces GKE AutopilotAutopilot is a new feature for Google’s managed Kubernetes service that aims to provide automated management of infrastructure or ‘true hands-free operations’ as they put it. While there are parallels with serverless ideas, I don’t really consider it such, but they do by quoting a customer who says “GKE Autopilot is the real serverless K8s platform that we’ve been waiting for.” So there you go.

In essence SST provides an environment where you can make changes to code live and stream real Lambda function invocations to this local code over WebSockets. This Hacker News thread provides more details from the creators.
