Excited to report my article "Digital Interdependence and Power Politics" has been published open access in @bjpols.bsky.social. I use internet measurements to understand how international security influences global data flows www.cambridge.org/core/journal...

Serials are useful for easy reference and disambiguating- that’s all it’s for. I serialize no matter the size or scope just for easy reference. Instead of saying “see report sent via email on 2 Feb 2025.” It doesn’t have to be anything more complicated than a +1 system: intel-1, intel-2, etc.

This was such a great conversation with @cyallianceprez.bsky.social and @intel.bsky.social - check it out. Information sharing has evolved - time for our policy to evolve, too.

Honestly, me right now. Pretty much exactly what I woke up thinking this morning.

You're right. But, practically speaking, given the size of any application's potential state graph, it's impossible to validate that hypothesis, and therefore, it's better to assume vulnerability than not.
