I can’t even keep up with this talk, they just showed two different(?) PoCs that spoof perfectly credible signatures from Satoshi and Angela Merkel.
The talk started with them booting a spoofed Fedora ISO after checking the signature.
14 vulns, 9 unpatched.

What's funny is you can tell exactly why it output this string.
When it stole literally all of Stack Overflow, it stole tons and tons of people's explanations of how to make a program that produces random character strings.
One of the easiest ways to do so, contains *this* ASCII string.

Every layer of the stack is getting faster. #Terraform isn't.

The Infrastructure Stack Is Getting Faster. Terraform Is Not.
Every part of the stack is accelerating except infrastructure. Terraform has the ecosystem but not the speed. That's fixable.

SemGrep has migrated to OCaml 5 with negligible performance impact.

They’ve had to do a bit of work to get a GC spacetime behaviour that matches OCaml 4. This feels like an issue with OCaml 5 GC scheduling. Needs investigation.
