ever wondered how to design directed energy weapons with OTC components, cheap china parts? and a custom PCB that we let the MuskAI design & we verify. why not add industrial/rugged components, burst, AM, FM, freq hopping & a epaper status display?

there's yet another stupid proposal - this time for debugging not middle box vendors - in the TLS working group to standardize key export among other encrypted traffic details. please don't. cryptolibs provide these & we all know how to handle wireshark.

A Robust Variant of ChaCha20-Poly1305: ia.cr/2025/222

"We present a new nonce-misuse resistant and key-committing authenticated encryption scheme, called ChaCha20-Poly1305-PSIV, that is based on carefully combining the ChaCha20-Poly1305 [...] into the NSIV paradigm [...] without performance loss."

TIL: so many tuns, tons, tonnes!

"Recent specialized uses include the ton as a means of truck classification. It can also be used as a unit of energy, or in refrigeration as a unit of power, sometimes called a ton of refrigeration."

there's some newer firewall vendors that seem to have forgotten that ikev1 and aggressive mode is an option that most FW vendors disabled on purpose some years back. and then there's the really crappy ones that only let you do certain tunnel types in aggressive mode.
