An unknown person joined the core team of a popular library where the author burned out and then inserted a backdoor. And large corporations continue to ignore the problem of burnout of library maintainers, on whom their business depends.

Don’t think that xz case is a case when you just need to downgrade your dependency. It is a case when your company should start supporting open source libraries your business relies on. Talk to your manager, use this case as an example “why it is important for the business”.

I love micro-optimizations (especially as onboarding challenges). @Konfuze wrote a custom PostCSS plugin for the reader that merge :root rules. We often use them in components. Also, I love custom @PostCSS plugins for project specific tasks. github.com/hplush/slowreader…

I’m updating slides for the "How to Make Popular Open Source Project" talk for the #OSDAY24 in Florence. I love to put references that nobody will understand.
