AuthN/Z is always a #security minefield & MCP adds even more complexity with agents, remote servers, and transitive trust.
This Teleport-sponsored deep dive breaks down attack vectors & why each authN/Z step is a potential trust boundary.

If anyone is friends with any Georgian air traffic controllers, buy them a nice bottle of wine. As guardians of pretty much the only narrow gap still available between Europe and Asia that avoids both Iran, the Gulf, Ukraine and Russia, they are under some substantial pressure.

I'm constantly trying (/failing) to get this point across.
If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers.
If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.

*very* striking to me that trump's two big losses at SCOUTS--first the fed, now tariffs--are both about core macroeconomic institutions, namely free trade and an independent central bank. "go nuts on culture, go nuts on immigration, but DO NOT TOUCH the neoliberal consensus"

1990s: you can inject code into data, but you need to learn assembly plus stack/heap management
2000s: you can inject code into data, and you only need to learn some Javascript

Absolutely unreal: I found a fifth bug in libcrux, this time in its PSQ implementation that would allow a denial of service via a malcrafted AES-GCM ciphertext.
I couldn't submit my PR: Cryspen blocked me after I submitted my first four PRs, which included a fix for a critical nonce reuse bug.

Looks like someone built a tool to check your LinkedIn network for names from the Epstein documents. Soon I expect other tools will follow to work with other social media platforms. This is what the beginning of what community accountability looks like. Just because the legal system is captured [β¦]

Economics of Orbital vs Terrestrial Data Centers
Interested in a rational discussion about the economics of orbital datacenters? Make some hypotheses (e.g.: launch cost, sunlight fraction, GPU degradation, etc.) and compare orbital vs terrestrial.
Code is public. Amazing work. Kudos.
