  3. Okta has been plagued by security issues [1], never heard of Ping Identity, Azure only makes sense if you get a sweetheart deal and are willing to deal with Azure's crap, and I'd never recommend anyone to use anything Google any more. [1] https://www.flyingpenguin.com/?p=54722

It's not so much that Copilot is a threat because it could produce tight, elegant code that handles all the edge cases and so on, but because employers still see coders as expensive keyboard jockeys whose code is not significantly better than what a Copilot user could cargo-cult into existence. Blaming Copilot feels a bit like the wrong target. Like the Luddites, the real question is the relationship between employe…

  17. The developer responsible for breaking the integrity of this commonly used software package is known as Brandon Nozaki Miller. It is public information that he is the maintainer. I think we will have to wait for him to announce if he personally did this or was hacked. TURN OFF AUTO UPDATES FOR DEPENDENCIES.
