Be alert: targeted attacks on prominent Rustaceans
We believe that there is an ongoing campaign targeting rust-lang members and owners of popular crates that is attempting to compromise devices and accounts in order to use them to publish malware. A video call is set up for something positive — maybe for a job, maybe for a project, maybe for a contract opportunity — and then that's used as a vector to either get the target to install something on their computer (such as a purportedly missing audio codec) or execute another command (for example, via putting a command on the clipboard).

Executable Scripts with Dependencies
The Unix shell is great for supporting executable scripts via the shebang header, but I’ve always found scripting languages limiting, due to the inability to specify dependencies (other than the standard library). This has always been Python’s appeal with its “batteries included”, but I dislike Python, and its standard library isn’t enough either. And then, Scala CLI has spoiled me, now being my favorite way to build scripts.
