I personally will continue to use "Gulf of Mexico" because our president is a wrathful felonious nincompoop with the intellect of paramecium and I do not consent to his cartographic buffoonery

EncyclopΓ¦dia Britannica will continue to use β€˜Gulf of Mexico’ for a few reasons:

-We serve an international audience, a majority of which is outside the U.S.

-The Gulf of Mexico is an international body of water, and the U.S.’s authority to rename it is ambiguous.

Analyzing ELF/Sshdinjector (IoT bot) with r2ai.

Really helpful and time save to use AI (with r2ai) for analysis *but* use it with a non-AI decompiler side by side:

1. To direct the AI
2. To spot more easily hallucinations or extrapolations.
