Zoom Sucks

• Zoom abuses the installer flow on MacOS to bypass permissions dialogs (source)
• Zoom sends identifying device info to Facebook, even when users don't have a Facebook account (source) (fixed)
• A bug in Zoom sent identifying information (including email addresses and profile pictures) of thousands of users to strangers (source)
• Zoom claims that meetings are end-to-end encrypted in their white paper and marketing materials, but meetings are only encrypted in transit, and are available in plaintext to Zoom servers and employees. (source)
• zoomAutenticationTool can be used to escalat

Common Lisp Scripting with Roswell

"Roswell Script" is implementation-independent Common Lisp scripting program which uses Roswell. Although Roswell itself is a unified interface to Common Lisp implementations, it also encourages writing scripts with it.

To start writing it, run ros init in your terminal:

$ ros init
Usage: ros init [template] name [options...]
