   I built a tool for policy driven vetting of open source packages▲7

   Linux Foundation survey says 70-90% of modern software constitute OSS code. Yet we are stuck with tools that scan only for vulnerabilities in 3rd party libraries and that too with high degree of false positives. I built `vet` for policy and data driven analysis of 3rd party packages that goes beyond only vulnerability and allows codifying organisational policies related to OSS consumption. https://github.com/safedep/vet Looking forward to feedback and suggestions from HN :)

    Shouldiuse.dev – Software dependency health checker▲13

    As software engineers we are often confronted with the decision of whether to code something ourselves or to add an existing library that does it for us. Whether we like it or not – we are adding dependencies sooner or later. And it's arguably good practice to check a new dependency beforehand: Is it maintained? By whom? How many issues does it have and how many of those are bugs? Are they being fixed? What's on the roadmap? What's the release frequency and how often do APIs break? One of our favorite solutions that already exist to answer such questions is the OpenSSF Scorecard project…
