how do airline PNRs get generated? there doesnt seem to be an obvious pattern so what stops two airlines generating the same PNR for unrelated bookings?

Supply chain attacks are here to stay. There is no easy tech mitigation - neither code signing nor reproducible builds solve it. Furthermore developers treat software like lego blocks and use more and more random dependencies (looking at you rust).

I thought @GTTCOMM filters RPKI invalids? I've come across an invalid they've been accepting for a couple of days: 45.42.246.0/24 (I own the prefix)

TIL that you can announce routes on IX route servers with communities set to further propagate routes only to specific ASs... this is quite dangerous since it opens the door to BGP hijacks that target traffic from specific ASs. I also hear that email spammers love this feature.

Investigating why an IP camera fell off my network... and it has changed its mac address while preserving all other configuration. Do I kill this thing with fire?

This is awesome and good for the IRR ecosystem before RPKI is more widely deployed. Let's end RADB next. arin.net/announcements/…

Is two factor auth transitive? i.e. I store a TOTP seed for a website in a password manager that is secured by 2FA with the seed on my phone. Is that just as secure as storing the the TOTP seed for the website directly on my phone?
